Specification

Description:FIELD OF THE INVENTION:
The present invention pertains to the field of neurosurgical instruments, specifically to probes designed for use in brain surgery. It focuses on enhancing precision and safety by incorporating a pressure sensitivity indicator, enabling real-time monitoring of applied pressure to minimize tissue damage during delicate neurosurgical procedures.

BACKGROUD OF THE INVENTION:
Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Neurosurgery is one of the most delicate and complex fields in modern medicine, requiring meticulous precision to ensure the safety and well-being of patients. The brain, being an intricate network of tissues, neurons, and blood vessels, is highly sensitive to external forces, making it particularly susceptible to damage during surgical interventions. Despite advancements in imaging technologies and surgical techniques, the risks associated with neurosurgery remain significant, primarily due to the inability to accurately monitor the amount of pressure applied by surgical instruments on delicate brain tissues. Excessive pressure during probing or manipulation can lead to irreversible damage, compromising the patient's neurological function and overall recovery. Consequently, the need for surgical tools that can provide real-time feedback during such procedures has become increasingly important.
Traditionally, neurosurgical probes have been passive instruments, serving as an extension of the surgeon's hand to explore, dissect, or manipulate brain tissue. While these tools have proven to be effective in many procedures, they lack the ability to provide quantitative data regarding the interaction between the probe and the tissues. Surgeons must rely on their tactile feedback and experience to gauge the force being applied, which introduces an element of subjectivity and variability to the process. In high-stakes scenarios, even slight deviations in pressure can result in complications such as tissue necrosis, vascular damage, or unintended brain edema. These challenges underscore the pressing need for innovative solutions that can bridge the gap between tactile perception and precise force measurement in neurosurgery.
Recent advancements in sensor technology and miniaturization have opened new avenues for the development of intelligent surgical instruments. Pressure sensors, in particular, have shown great potential in enabling real-time monitoring of applied force in various medical applications. However, integrating such sensors into neurosurgical tools poses unique challenges. The sensors must be small and lightweight to ensure the probe remains easy to handle and maneuver in confined spaces. Additionally, the materials used must be biocompatible and capable of withstanding sterilization processes to maintain the probe's safety and efficacy during repeated use. Furthermore, the pressure sensitivity range must be carefully calibrated to detect minute variations in force while avoiding false readings or oversensitivity, which could hinder the surgeon's workflow.
Despite these challenges, researchers have made progress in developing pressure-sensitive surgical instruments, though many remain in experimental stages or are limited to broader surgical applications. Instruments specifically tailored for neurosurgery, which demands unparalleled precision and sensitivity, are still rare. Existing neurosurgical tools equipped with advanced features often focus on navigation or imaging integration rather than force feedback. While these technologies enhance the surgeon's ability to visualize and plan the procedure, they do little to address the risk of physical damage caused by improper force application. This gap highlights an unmet need for tools that combine tactile functionality with advanced feedback mechanisms, enabling surgeons to make informed decisions in real-time.
The present invention seeks to address this need by introducing a neurosurgical probe with an integrated pressure sensitivity indicator. Unlike conventional probes, this instrument incorporates micro-scale pressure sensors embedded along its shaft or tip. These sensors are designed to detect the force exerted on tissues and relay this information to a connected display unit or wearable device. The feedback provided by the system enables surgeons to adjust their techniques dynamically, reducing the likelihood of accidental damage. The probe is also designed to be compatible with existing neurosurgical workflows, ensuring seamless integration into standard surgical setups without requiring significant retraining or procedural modifications.
One of the key innovations of this probe is its real-time feedback system, which utilizes visual or auditory cues to inform the surgeon of the applied pressure. For instance, the system could include a color-coded display that transitions from green to yellow to red as the force increases, providing an intuitive and immediate understanding of the pressure being exerted. Alternatively, it could emit auditory signals with varying frequencies to indicate the force level, allowing the surgeon to focus on the procedure without needing to glance at a monitor. This flexibility in feedback mechanisms ensures that the probe can accommodate the diverse preferences and working styles of neurosurgeons.

By mitigating the risk of tissue damage, the invention seeks to enhance the safety and efficacy of neurosurgical procedures, ultimately contributing to faster recovery times and better long-term prognoses.
Still another object of the invention is to offer a device that seamlessly integrates into existing neurosurgical workflows without requiring extensive modifications or retraining. The ergonomic and lightweight design ensures that the added functionality of the pressure sensitivity indicator does not compromise the usability of the probe during prolonged surgical procedures.
A further object of the invention is to support advancements in surgical education and training by providing a tool that can objectively measure and display force application. This capability allows aspiring neurosurgeons to develop refined pressure control skills, contributing to the standardization and improvement of surgical techniques.

With reference to FIG. 1,
The neurosurgical probe with a pressure sensitivity indicator (100) is a groundbreaking innovation aimed at improving the safety and precision of brain surgeries. This device comprises an ergonomic probe body (10), which is specifically configured for manual use during neurosurgical procedures. The ergonomic design of the probe body (10) ensures that surgeons can handle it comfortably and efficiently, even during extended surgical operations. The probe body (10) is shaped to fit naturally in the hand, reducing fatigue and allowing precise maneuverability in the confined and delicate spaces of the brain.
Embedded at the distal end (12) of the probe (11) are one or more micro-scale pressure sensors (20). These sensors (20) are strategically placed to detect the force exerted on brain tissues during surgical procedures. The sensors (20) operate with a high degree of sensitivity, capable of detecting minute variations in applied force ranging from 0.01 N to 10 N. This range is specifically chosen to suit the delicate nature of neurosurgical applications, where even slight deviations in pressure can have significant consequences on the integrity of the tissues. The precise placement of the sensors (20) ensures accurate force measurement at the critical point of interaction between the probe and the tissues.
The pressure sensors (20) are operatively connected to a feedback system (30) that provides real-time feedback to the surgeon. This feedback system (30) is a critical component of the probe (100), designed to translate the data collected by the sensors (20) into actionable information. The feedback system (30) includes a color-coded visual display (32) that transitions through different colors to indicate varying levels of pressure. For instance, the display (32) may show green for safe pressure levels, yellow for moderate pressure requiring caution, and red for excessive pressure that could potentially damage tissues. This intuitive visual feedback allows the surgeon to quickly interpret the applied force and adjust their technique as necessary.
In addition to the visual display (32), the feedback system (30) also includes an auditory signal generator (34). This auditory component emits sounds of varying frequencies that correspond to different pressure levels. The inclusion of an auditory signal generator (34) is particularly useful for surgeons who prefer not to divert their visual attention away from the surgical site. By listening to the frequency of the auditory signals, the surgeon can maintain focus on the procedure while still receiving real-time pressure feedback. This dual feedback mechanism ensures that the probe (100) accommodates diverse preferences and working styles of neurosurgeons.
The biocompatible and sterilizable casing (40) encloses all the internal components, including the pressure sensors (20) and the feedback system (30). The casing (40) is constructed from materials that are resistant to high-temperature sterilization processes, ensuring that the probe (100) remains safe for repeated use in surgical environments. The choice of materials for the casing (40) prioritizes both durability and biocompatibility, safeguarding against contamination and maintaining the integrity of the embedded sensors (20) and electronic components.
The probe (100) is further enhanced by the inclusion of a data interface that allows the transmission of pressure data to external devices such as monitors or wearable displays. This feature enables enhanced visualization and analysis of the force data during the procedure. Surgeons can utilize this data interface to observe trends and patterns in real-time, facilitating better decision-making during critical moments of the operation. The stored data can also be analyzed post-operatively for quality assurance and training purposes, contributing to the continuous improvement of surgical techniques.
Another significant feature of the neurosurgical probe (100) is the programmability of the feedback system (30). Surgeons can customize the pressure thresholds and feedback modes based on the specific requirements of the surgical procedure. For example, the pressure sensitivity range and feedback intensity can be adjusted for procedures involving particularly fragile tissues or areas with higher risks of vascular complications. This adaptability ensures that the probe (100) remains versatile and applicable across a wide range of neurosurgical scenarios.
The ergonomic design of the probe body (10) plays a vital role in enhancing its usability. The contoured grip and lightweight construction are meticulously designed to reduce hand fatigue during prolonged surgeries. This feature ensures that the added functionality of the pressure sensitivity indicator does not compromise the ease of use or maneuverability of the probe (100). The ergonomic enhancements make the probe (100) a practical tool for surgeons, combining advanced technology with user-centric design.
The method of using the neurosurgical probe (100) begins with positioning the probe at the surgical site. Once positioned, the embedded pressure sensors (20) detect the force exerted by the probe (11) on the target tissues. The data collected by the sensors (20) is transmitted to the feedback system (30), which provides real-time feedback through the visual display (32) and auditory signal generator (34). This immediate feedback allows the surgeon to dynamically adjust the applied force, ensuring optimal precision and minimizing the risk of tissue damage.
During the procedure, the pressure data can be continuously transmitted via the data interface to an external device for real-time analysis. This data provides valuable insights into the interaction between the probe (100) and the tissues, enabling the surgeon to refine their technique dynamically. Additionally, the collected data can be stored for post-operative analysis and training, offering a quantitative basis for improving surgical practices and educating aspiring neurosurgeons.
The neurosurgical probe (100) is not limited to neurosurgery alone. Its design and functionality make it adaptable for use in other delicate surgical fields, such as ophthalmology and microsurgery, where precise control of applied force is equally critical. Furthermore, the integration of pressure-sensitive technology into surgical tools has the potential to advance robotic-assisted surgeries, addressing the longstanding limitation of tactile feedback in such procedures. By providing quantitative feedback on force application, the probe (100) enhances the accuracy and safety of robotic-assisted surgeries, broadening its impact across the surgical spectrum.
In addition to its immediate benefits for surgeons, the neurosurgical probe (100) has significant implications for patient outcomes. By minimizing the risk of tissue damage, the probe (100) reduces the likelihood of post-operative complications and accelerates recovery times. The ability to provide objective data on force application also supports standardization of surgical techniques, contributing to consistent and improved patient care.
The neurosurgical probe with a pressure sensitivity indicator (100) represents a significant advancement in surgical instrumentation. By addressing the limitations of conventional probes and incorporating state-of-the-art sensor technology, this invention transforms the way neurosurgery is performed. Its combination of real-time feedback, ergonomic design, and adaptability makes it a valuable tool for enhancing precision, safety, and usability in delicate surgical procedures. As the field of surgery continues to embrace technological innovation, tools like the neurosurgical probe (100) will play a crucial role in shaping the future of surgical care.

The neurosurgical probe with a pressure sensitivity indicator works by integrating advanced sensing and feedback mechanisms to provide real-time information about the pressure exerted on delicate brain tissues during neurosurgery. The working of the invention is described in the following steps:
1. Probe Positioning and Handling: The ergonomic probe body is designed for easy handling and precise maneuvering. The neurosurgeon holds the probe, positioning its distal end at the surgical site. The contoured grip of the probe minimizes hand fatigue and ensures a steady hold during the procedure, enabling the surgeon to navigate the intricate areas of the brain with precision.
2. Force Detection via Pressure Sensors: The micro-scale pressure sensors embedded at the distal end of the probe continuously measure the force exerted on the tissues. These sensors are designed to detect minute variations in applied pressure within a range of 0.01 N to 10 N. The high sensitivity of the sensors ensures accurate detection of even the slightest changes in pressure, which is crucial for avoiding tissue damage during neurosurgical procedures.
3. Data Processing: The detected pressure data is immediately transmitted to the feedback system integrated within the probe. This data is processed in real-time to evaluate whether the applied force falls within the safe range for the specific surgical procedure being performed. The processing system interprets the sensor signals and converts them into actionable feedback for the surgeon.
4. Feedback Mechanism: The feedback system provides real-time alerts to the surgeon through two primary modes:
i. Visual Feedback: A color-coded display transitions between colors (e.g., green for safe pressure, yellow for moderate pressure, and red for excessive pressure). This visual representation offers an intuitive understanding of the applied force, allowing the surgeon to adjust their actions accordingly.
ii. Auditory Feedback: An auditory signal generator emits sounds of varying frequencies corresponding to different pressure levels. This auditory feedback enables the surgeon to receive alerts without needing to glance away from the surgical site, ensuring continuous focus on the procedure.
5. Dynamic Adjustments by the Surgeon: Based on the real-time feedback, the surgeon dynamically adjusts the applied force during the procedure. If the feedback indicates excessive pressure, the surgeon can immediately reduce the force to prevent potential damage to the tissues. This closed-loop interaction between the probe and the surgeon enhances precision and minimizes risks.
6. Data Transmission and Analysis: The processed pressure data can be transmitted to an external device, such as a monitor or wearable display, through a data interface. This feature allows for enhanced visualization of the applied force in graphical or numerical formats, aiding in better decision-making during the surgery. The data can also be stored for post-operative analysis, enabling detailed reviews of the procedure and contributing to surgical training and quality assurance.
7. Programmability of Feedback System: The feedback system can be programmed to customize pressure thresholds and feedback modes according to the specific requirements of the surgical procedure. For instance, in surgeries involving particularly fragile tissues, the thresholds can be set to alert the surgeon at lower pressure levels, ensuring maximum caution. This customization enhances the probe's versatility across different neurosurgical applications.
8. Sterilization and Reusability: After the surgical procedure, the probe is sterilized using standard high-temperature methods. The biocompatible and sterilization-resistant materials used in the probe's casing ensure that its components, including the pressure sensors and feedback system, remain intact and functional after repeated sterilizations. This durability ensures the probe's long-term usability in various surgical environments.
9. Applications Beyond Neurosurgery: The probe's functionality is adaptable for other surgical fields, such as ophthalmology, microsurgery, and robotic-assisted surgeries. Its ability to measure and provide feedback on applied force enhances precision in these fields as well. For robotic-assisted procedures, the probe can transmit force data to robotic systems, enabling more controlled and accurate operations.
The working of the neurosurgical probe is designed to enhance the surgeon's ability to perform delicate procedures with greater precision and safety. By providing real-time feedback on applied pressure, the invention significantly reduces the risks of unintended tissue damage, improving patient outcomes and advancing surgical practices.
