Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a push-pull sliding neuroendoscopic aspirator system. Background Technology

[0002] Current neuroendoscopic procedures require the coordinated operation of a neuroendoscope (1), a suction device (2), and an electrocoagulator. The surgeon needs an assistant to hold the endoscope, and complex surgeries may require two people with four hands. Poor coordination, obstructed surgical field, frequent instrument switching between suction and electrocoagulation, prolonged surgery time, and increased risk of tissue damage are all problems. The separation of the endoscope and instruments results in low positioning accuracy, making precise close observation and synchronous operation difficult, affecting minimally invasive outcomes and surgical safety. Furthermore, in traditional neuroendoscopic procedures, the suction device (2) and endoscope are independent instruments. During suction, the operating space is increased, requiring an assistant to hold the suction device (2) and insert it into the surgical field from outside or at the edge of the endoscope's view. This not only easily leads to obstruction of the surgeon's field of vision due to mutual instrument blockage, affecting precise observation of the lesion area, but also may cause unnecessary contact or traction on surrounding normal tissue due to improper force or angle of the assistant's operation. Meanwhile, because the suction device 2 is separate from the endoscope, it is difficult to achieve completely synchronized positional adjustments. When suction is needed for a specific area, the position of the tip of the suction device 2 often needs to be repeatedly adjusted to align with the target, prolonging the operation time and increasing the interference with the stability of the surgical field due to frequent instrument movement. In addition, the traditional suction device 2 has a single function, only capable of suction. If dissection, exploration, or other operations are required during the surgery, the surgeon must stop the suction operation and change the corresponding instrument. This process not only interrupts the continuity of the surgery but also further increases the surgical risk and patient trauma. The assistant must hold the suction device 2 alone, which not only consumes surgical personnel resources but also makes it difficult to effectively coordinate the suction operation with endoscopic observation. When bleeding occurs in the surgical field or tissue debris needs to be removed, the assistant must precisely control the suction device 2 to align with the target area, while the surgeon must simultaneously adjust the endoscopic field of view to coordinate with the suction. During this process, the rhythm and positional coordination of the two operations are often difficult, which can easily lead to untimely suction or suction position deviation, thus affecting the rapid recovery of surgical field clarity.

[0003] The disadvantages of existing technologies include: Poor operational coordination: The surgical field is easily obstructed, and the need to frequently switch between neuroendoscopy, suction and electrocoagulation prolongs the operation time and increases the risk of tissue damage. The separate operation requires a higher degree of tacit understanding between the assistant and the surgeon. Once the coordination is deviated, it will not only affect the efficiency of the operation, but may also cause unnecessary damage to the surrounding normal tissues due to misoperation, which is not conducive to the precise implementation of the operation. This places certain requirements on the operator's skills and experience.

[0004] The suction device 2 is separated from the endoscope: The endoscope is easily contaminated, and repeated wiping of the lens makes it difficult to achieve completely synchronized positional adjustments between the two. When suction is needed for a specific area, the position of the tip of suction device 2 often needs to be repeatedly adjusted to align with the target, prolonging the operation time and increasing the interference of frequent instrument movement on the stability of the surgical field. A deeper problem is that this separate structure disrupts the natural surgical logic chain of "observation-judgment-intervention".

[0005] Increased operating space: The increased operating space in the combined operation path of neuroendoscopy 1 and suction device 2 can easily lead to mutual interference or collision between instruments. This is especially true in deep and narrow surgical fields, where the spatial limitations of multi-instrument collaborative operation are more pronounced, further exacerbating the difficulty of operation and surgical risks.

[0006] Limited functionality: Traditional suction device 2 only has suction function. If dissection, exploration or other operations are required, the surgeon must interrupt the suction action to change the device. This not only disrupts the continuity of the operation and prolongs the operation time, but also increases the interference to the surgical field and surgical risks that may be caused during the device change process.

[0007] Human resource consumption: The assistant must hold the suction device 2 alone, which not only consumes valuable surgical personnel resources but also makes it difficult to achieve a high degree of coordination between suction and endoscopic observation. When bleeding occurs in the surgical field or tissue debris needs to be removed, the assistant must precisely control the suction device 2 to aim at the target area, while the surgeon must simultaneously adjust the endoscopic field of view to coordinate with the suction. During this process, the rhythm and position coordination of the two operations are often difficult, which can easily lead to untimely suction or suction position deviation, thus affecting the rapid recovery of surgical field clarity.

[0008] Disadvantages of existing neuroendoscopic surgical techniques

[0009] Poor coordination leads to low surgical efficiency and high risk. The surgery requires the use of multiple instruments, including a neuroendoscopy unit, suction device, and electrocoagulator. The surgeon needs an assistant to hold the endoscope, and complex surgeries require two surgeons with four hands, demanding high levels of team coordination. The surgical field is easily obstructed by instruments, and suction and electrocoagulation require frequent instrument changes, significantly prolonging the operation time. Furthermore, frequent instrument insertion and switching increases the risk of damage to normal tissues, requiring a high level of experience and close teamwork from the surgeons. Deviations in coordination can easily lead to errors, hindering precise surgical execution.

[0010] The separation of the endoscope and aspirator leads to poor positioning and synchronization. As independent instruments, their positions are difficult to adjust synchronously. When aspirating the target area, the aspirator tip needs repeated calibration, further prolonging the operation time and interfering with surgical field stability. Furthermore, the separate structure easily causes endoscope contamination, requiring repeated wiping and disrupting the surgical rhythm. More importantly, this structure breaks the surgical logic chain of "observation-judgment-intervention," making precise close observation and synchronous operation difficult, directly reducing the effectiveness of minimally invasive procedures and surgical safety.

[0011] Occupying operating space and causing significant instrument interference: Independent suction devices need to be extended into the surgical field from outside or at the edge of the endoscopic field, taking up additional operating space, which is particularly prominent in deep and narrow surgical field environments. Parallel operation of multiple instruments is prone to collisions and obstruction, which not only limits the surgeon's field of vision and affects the accurate observation of the lesion area, but may also increase the difficulty of operation and surgical risks due to instrument interference.

[0012] Traditional suction devices have a single function and disrupt the continuity of surgery. They only have a simple suction function. When surgery requires procedures such as tissue dissection or lesion exploration, suction must be interrupted and the device changed. This process disrupts the continuity of the surgical procedure, prolongs the total operation time, and the device change process can easily disturb the surgical field, further increasing surgical trauma and risks.

[0013] It consumes human resources and is difficult to coordinate, affecting emergency treatment. Suctioning requires an assistant to hold the instrument alone, which requires additional surgical manpower. Moreover, the suction action and endoscopic observation are difficult to coordinate efficiently. When there is sudden bleeding in the surgical field or tissue debris removal, the operating rhythm and position adjustment of the surgeon and assistant are prone to deviation, which can lead to problems such as untimely suction and inaccurate positioning. It is impossible to quickly restore the clarity of the surgical field, which affects the emergency treatment and surgical safety during the operation. Summary of the Invention

[0014] Purpose of the invention: To provide a more effective push-pull sliding neuroendoscopic aspirator system, the specific purpose of which is described in the detailed implementation section for several substantial technical effects.

[0015] To achieve the above objectives, the present invention adopts the following technical solution: A push-pull sliding neuroendoscopic aspirator system, characterized in that, One or more guiding auxiliary structures are arranged on the body of the neuroendoscopy 1. The guiding auxiliary structure includes multiple sets of guiding rings, through which a suction device 2 passes. A hollow soft dissection structure 3 is arranged at the end of the suction device 2. The suction device 2 can be relatively positioned and pumped within the guide ring.

[0016] A further technical solution of the present invention is that the guide ring includes a semi-closed guide ring 5 and a closed guide ring 4; wherein the closed guide ring 4 is used for bottom positioning.

[0017] A further technical solution of the present invention is that the suction device 2 includes a suction control switch 6.

[0018] A further technical solution of the present invention is that the rubber ring 10 is elastically fitted onto the body of the neuroendoscope; the sleeve 9 is used to pass through the semi-closed clamping structure 5, which is made of plastic with clamping force.

[0019] A further technical solution of the present invention is that the suction control switch 6 is integrated into the handheld part of the neuroendoscope 1, which is convenient for one-handed operation.

[0020] A further technical solution of the present invention is that the clamping force of the semi-enclosed clamping structure 5 is insufficient to block the push-pull sliding of the suction device.

[0021] A further technical solution of the present invention is that the soft peeling structure 3 is a hollow tube made of medical-grade silicone.

[0022] The present invention, employing the above technical solution, offers the following advantages over existing technologies: This patent addresses numerous shortcomings of current neuroendoscopic surgeries, including poor coordination, low efficiency, high risk, poor positioning synchronization due to the separation of the endoscope and aspirator, large instrument space requirements leading to mutual interference, limited aspirator functionality, high labor costs, and difficulties in emergency handling. It proposes an integrated innovative design. This solution integrates the neuroendoscope and aspirator into one unit. The endoscope body features multiple guide rings for the aspirator to pass through, position, and move. The aspiration control switch is integrated into the handheld part, allowing the surgeon to independently perform observation and aspiration operations with one hand, eliminating the need for traditional two-person collaboration. The aspiration channel runs parallel to the endoscope body, with the aspiration port close to the surgical field and capable of synchronous sliding adjustment. The angle and size of the front aspiration port are adjustable, enabling precise removal of accumulated blood and debris, avoiding lens contamination, and eliminating the need for frequent wiping. The integrated structure reduces the space occupied during operation, and the guide structure standardizes the aspirator's movement path, preventing instrument collisions and obstructions. The aspirator end features a medical-grade silicone soft dissection structure, combining aspiration and gentle dissection functions, reducing tissue damage and instrument replacement. The overall solution simplifies the operation process, improves surgical coordination, accuracy and continuity, saves manpower, enhances intraoperative emergency response capabilities, and significantly reduces surgical trauma and risks.

[0026] This patent provides multiple parallel solutions; the different descriptions represent improved solutions or parallel solutions based on the basic solution. Each solution has its own unique characteristics. Furthermore, the technical features involved in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other. Fixing methods not described herein can be any type of fixing, such as threaded fixing, bolt fixing, or adhesive bonding.

[0027] The choice of materials used in an invention does not limit the scope of protection.

[0028] Example 1: Referring to all the accompanying drawings; A push-pull sliding neuroendoscopic aspirator system, characterized in that, One or more guiding aid structures are arranged on the body of the neuroendoscope 1. Each guiding aid structure includes multiple sets of guide coils, through which a suction device 2 passes. The end of the suction device 2 is provided with a hollow, soft dissection structure 3. The suction device 2 can be relatively positioned and pulled within the guide coils. The guide coils include a semi-closed guide coil 5 and a closed guide coil 4; the closed guide coil 4 is used for bottom positioning. The suction device 2 includes a suction control switch 6. The suction control switch 6 is integrated into the handheld part of the neuroendoscope 1 for convenient one-handed operation.

[0029] 1. Addressing the shortcomings of existing technologies, such as poor operational coordination, low surgical efficiency, and high risk, this patent innovatively and non-obviously integrates the neuroendoscope 1 and the suction device 2 into a single structural design. Multiple guide rings are arranged within the neuroendoscope 1, with the suction device 2 inserted within these rings for relative positioning and movement. Simultaneously, the suction control switch 6 is integrated into the handheld portion of the neuroendoscope 1, allowing the surgeon to simultaneously operate the neuroendoscope 1 for observation and the suction device 2 with a single hand, eliminating the need for an assistant to hold the endoscope and abandoning the traditional two-person, four-handed operation mode. This design allows suction and electrocoagulation to be performed simultaneously under the neuroendoscope 1, eliminating the need for frequent instrument switching, significantly reducing the coordination difficulty of team operations, minimizing the risk of tissue damage from frequent instrument insertion and removal, improving the coordination and precision of surgical operations, shortening surgical time, and reducing the possibility of errors caused by coordination deviations.

[0030] 2. Addressing the shortcomings of existing technologies such as "separation of endoscope and suction device, resulting in poor positioning and synchronization," this patent innovatively and non-obviously sets the suction channel and the neuroendoscope 1 body in parallel, keeping the suction port of the suction device 2 and the lens of the neuroendoscope 1 in a similar surgical field area. Furthermore, the suction device 2 can slide and push within the guide coil, achieving synchronized positional adjustment between the suction device 2 and the neuroendoscope 1 without the need for repeated calibration of the suction device 2 tip position. Simultaneously, the device's front end features an adjustable suction port, the opening size and angle of which can be flexibly adjusted via a control device on the handle. This allows for precise targeting of bleeding points, areas of tissue debris accumulation, and other target locations, promptly removing contaminants and preventing contamination of the neuroendoscope 1 lens. This eliminates the need for repeated lens wiping, which disrupts the surgical rhythm, reconstructing the natural surgical logic chain of "observation-judgment-intervention," achieving precise close-range observation and synchronized operation, and improving minimally invasive outcomes and surgical safety.

[0031] 3. Addressing the shortcomings of existing technologies, such as "occupying operating space and significant instrument interference," this patent innovatively and non-obviously integrates the neuroendoscope 1 and the suction device 2 into one unit. This combines two instruments, which previously required independent operation, onto the same operating path, replacing the traditional method of extending the suction device 2 from outside or at the edge of the neuroendoscope 1's field of view. This effectively reduces the operating space occupied by the working channel. Simultaneously, the guide auxiliary structure, with its bottom positioning of the closed guide ring 4 and elastic clamping of the semi-closed guide ring 5, standardizes the movement path of the suction device 2, avoiding collisions and obstructions caused by parallel operation of multiple instruments. Even in narrow surgical fields such as those deep within the skull, instrument interference is reduced, the surgeon's effective field of view is expanded, the accuracy of observation of the lesion area is improved, and the operational difficulty and surgical risk are reduced.

[0032] 4. Addressing the shortcomings of existing technologies where "the suction device has a single function, disrupting the continuity of surgery," this patent innovatively and non-obviously incorporates a hollow, soft dissection structure 3 made of medical-grade silicone at the end of the suction device 2. This allows the suction device 2 to perform both suction and gentle tissue dissection, eliminating the need to interrupt suction to replace the dissection instrument. The soft dissection structure 3 can perform tissue dissection operations according to the needs of the surgical field with minimal tissue damage, avoiding the nerve and blood vessel traction and compression damage caused by traditional rigid instruments. It simultaneously performs dissection and exploration operations while performing suction, ensuring the continuity of the surgical procedure, reducing disturbance to the surgical field during instrument changes, and lowering surgical trauma and risks.

[0033] 5. Addressing the shortcomings of existing technologies that "consume significant manpower, are difficult to coordinate, and hinder emergency response," this patent innovatively and non-obviously incorporates an integrated structural design and a suction control switch 6 integrated into the handheld component. This allows the surgeon to perform the entire core procedure—observation with the neuroendoscopy 1, suction with the suction device 2, and dissection—with a single hand, eliminating the need for an assistant to hold the suction device 2 separately, thus saving valuable surgical personnel resources. Simultaneously, the synchronized movement and precise suction design of the suction device 2 and the neuroendoscopy 1 allow the surgeon to independently control the timing and position of suction, avoiding deviations in the surgeon's and assistant's operational rhythm and position adjustments. In the event of sudden bleeding or tissue debris accumulation in the surgical field, suction can be quickly and accurately activated and aligned with the target, promptly restoring clarity of the surgical field, improving intraoperative emergency response capabilities, and ensuring surgical safety.

[0034] 1. Neuroendoscopy 1 is a minimally invasive surgery with a small operating space. The coordinated operation of suction device 2 and neuroendoscopy 1 increases the operating space. The suction device 2 system, in conjunction with neuroendoscopy 1, further improves and optimizes the operating space limitation. 2. It solves the problem that neuroendoscopic surgery requires four hands, which increases the workload and the possibility of surgical errors. It eliminates the need for an assistant to hold the endoscope, allowing the surgeon to simultaneously perform suction and electrocoagulation under the neuroendoscopy, making neuroendoscopic surgery more flexible and precise.

[0035] 3. This system features a push-pull sliding design, showcasing the advantage of close-range observation with the neuroendoscope 1. As needed during the procedure, the suction device 2 continuously draws suction to maintain a clear surgical field, while the push-pull sliding system adjusts the neuroendoscope 1 to provide closer observation. This push-pull sliding structure also enables real-time intraoperative fine-tuning—dynamic adaptation of focal length and depth of field can be achieved without interrupting suction.

[0036] 4. Equipped with a soft dissection structure at the tip 3, it can gently dissect tissue according to the needs of the surgical field, minimizing tissue damage. This avoids the risk of traction or compression damage to surrounding nerves, blood vessels, and other fragile structures caused by the tip of a traditional rigid suction device 2 during dissection operations. It is especially suitable for surgical scenarios requiring extremely high operational precision, such as deep brain surgeries and functional areas, further ensuring the safety of the surgery.

[0037] This device features an integrated design that combines a neuroendoscope (1) and a suction device (2), with the suction channels positioned parallel to the endoscope body to ensure the suction port and endoscope lens are located in close proximity within the surgical field. An adjustable suction port is located at the front of the device; its opening size and angle can be flexibly adjusted via a control device on the handle, ensuring precise targeting of the desired suction location, such as bleeding points or areas of tissue debris, without contamination of the endoscope. Simultaneously, a suction control switch (6) is integrated into the handle, allowing the surgeon to easily activate or deactivate the suction function or adjust the suction intensity with a simple operation using their thumb or forefinger, enabling simultaneous one-handed operation of endoscopic observation and suction.

[0038] It also features a push-pull sliding structure and a soft peeling structure.

[0039] The core idea of ​​this invention is to integrate the neuroendoscope 1 and the suction device 2 into a single design. By arranging multiple sets of guide rings on the neuroendoscope 1 body, the suction device 2 is positioned and moved relative to the guide rings. The end of the suction device 2 is provided with a hollow soft dissection structure 3. The core is to make the suction device 2 an organic part of the neuroendoscope 1, realizing the integrated synergy of synchronous movement, single-handed operation, and functional expansion. In contrast, CN204073062U, CN215192913U, and CN221692212U are all external combinations / bindings of the suction device and the endoscope, which do not achieve true structural integration. They only solve the basic problem of "instrument placement / synchronous movement" and do not address the reconstruction of the "observation-judgment-intervention" logic chain in surgical operation, nor do they expand the function of the suction device itself. The overall idea is still "external cooperation of independent instruments", which is completely different from the core idea of ​​"integrated fusion, functional integration, and single-handed operation" of this invention.

[0040] (a) Defects of CN204073062U The suction device 1, irrigation tube 2, and neuroendoscopy fixation tube 3 are externally integrated using an outer tube 4. The neuroendoscopy needs to be fixed inside the fixation tube by a positioning bolt 5. After fixation, the suction device and the neuroendoscopy cannot be pushed, pulled, and slid synchronously. Tightening / loosening the positioning bolt 5 will interrupt the surgical rhythm, and there is still a problem of poor positioning and synchronization. It only achieves the "same tube placement" of suction, irrigation and endoscope. The suction device has no additional functional expansion and still only has the simple suction function. During the operation, dissection and exploration still require changing instruments, which disrupts the continuity of the operation. The outer tube 4 is an integrated structure, which still occupies a large operating space. In addition, the design of multiple tube welding connections makes the instrument less flexible and unsuitable for deep and narrow surgical fields. Although rinsing and suction can be performed with one hand, the angle of view is limited after the neuroendoscopy is fixed, and it is still impossible to achieve real-time dynamic coordination between endoscopic observation and suction operation, thus not truly reducing the dependence on assistants.

[0041] (ii) Defects of CN215192913U The slide sleeve 2 is only set on the inner ear lens body 1 to allow the suction device 3 to move back and forth. The slide sleeve 2 is a fixed structure without precise guidance and positioning design. The movement path of the suction device 3 is easy to deviate, and the positioning accuracy in the surgical field is low. This design is only compatible with ear endoscopes and does not take into account the need for deep and narrow surgical fields in neuroendoscopic surgery. The thin structure of the sliding sleeve 2 lacks protection and restraint, which can easily cause instrument collision or tissue damage. The suction device 3 can only move back and forth without any functional expansion. It still only has the suction function and cannot perform operations such as dissection and exploration. Frequent instrument changes are still required during surgery. The cooperation between the sliding sleeve 2 and the suction device 3 only enables "the hand holding the mirror to control the suction". There is no integrated control switch design, and the suction function still requires additional operation to turn on and off, which is not convenient to operate.

[0042] (III) Defects of CN221692212U The external binding of the aspirator and endoscope is achieved solely through the C-shaped structure of the endoscope clip 1 and the aspirator clip 2. The connection of the clips is a flexible binding without a rigid guide structure. The aspirator is prone to shaking and displacement during movement, resulting in extremely low positioning accuracy. Although the length of the suction device can be adjusted by sliding, it lacks a limiting and guiding design for synchronous movement, making it impossible to achieve precise synchronous adjustment of the suction device and endoscope. The position of the suction device tip needs to be repeatedly calibrated in the surgical field. This device is an "additional adjustment structure," which increases the overall volume of the instrument. In deep and narrow surgical fields, it will further increase the occupation of operating space and easily cause instrument interference. The solution only addresses the issue of "binding and moving" between the suction device and the endoscope, without expanding the suction device's functionality or designing an integrated control structure. The surgery still requires multiple people to cooperate and frequent instrument changes, thus failing to improve surgical efficiency.

[0043] (i) In response to the defect of CN204073062U that “it cannot be pushed, pulled and slid synchronously after fixation, and the operation interrupts the surgical rhythm”, this patent innovatively and non-obviously arranges multiple sets of guide rings (closed guide ring 4 and semi-closed guide ring 5) on the neuroendoscope 1 body, so that the suction device 2 is inserted in the guide ring to achieve relative positioning and free movement without fixation. It abandons the rigid fixation method of positioning bolts. The suction device 2 can be pushed, pulled and slid synchronously with the angle of the neuroendoscope 1 without additional operation to unlock / fix it. It realizes the dynamic synchronous position adjustment of the suction device 2 and the neuroendoscope 1, reconstructs the surgical logic chain of “observation-judgment-intervention”, and avoids the impact of operation interruption on the surgical rhythm.

[0044] (ii) In response to the shortcomings of CN204073062U, which states that "the suction device has a single function and requires replacement of instruments", this patent innovatively and non-obviously sets a hollow soft dissection structure 3 made of medical-grade silicone at the end of the suction device 2, so that the suction device 2 has the dual functions of suction and gentle dissection. During the operation, tissue dissection and exploration can be completed while continuously suctioning, without interrupting suction and replacing instruments, thus ensuring the continuity of the surgical procedure. At the same time, the soft material avoids the traction and compression damage to nerves and blood vessels caused by hard instruments.

[0045] (III) In response to the shortcomings of CN215192913U, namely "no precise guidance and positioning, and easy deviation of the suction device's movement path", this patent innovatively and non-obviously designs a combined guide structure of closed guide ring 4 and semi-closed guide ring 5. The closed guide ring 4 achieves bottom positioning of the suction device 2, and the semi-closed guide ring 5 constrains the path of the suction device 2 through elastic clamping. The two work together to standardize the movement path of the suction device 2, completely avoid the problem of deviation and shaking of the suction device 2, and greatly improve the positioning accuracy in the surgical field, adapting to the needs of deep and narrow surgical fields in neuroendoscopic surgery.

[0046] (iv) In response to the shortcomings of CN215192913U, which is "lacking an integrated control switch and lacking ease of operation", this patent innovatively integrates the suction control switch 6 into the handheld part of the neuroendoscope 1 in a non-obvious way. The surgeon can use his thumb / index finger to observe the neuroendoscope 1, turn the suction control switch 6 on and off, and adjust the suction intensity with one hand without additional hand operation. This achieves one-handed integrated control of "observation-suction", which greatly improves the convenience of surgical operation.

[0047] (v) In response to the defects of CN221692212U, which is that "external binding has no rigid guidance and the suction device is easy to shake and deviate", this patent innovatively and non-obviously places the guide ring directly on the body of the neuroendoscope 1, so that the suction device 2 and the neuroendoscope 1 form an organic integrated structure, rather than an externally attached binding structure. The rigid guidance design of the closed guide ring 4 and the semi-closed guide ring 5 ensures that the movement of the suction device 2 always follows the path of the endoscope body, completely solving the shaking and deviating problems caused by external binding, and realizing the precise synchronous movement of the suction device 2 and the neuroendoscope 1.

[0048] (vi) In response to the shortcomings of CN221692212U, which states that "additional structures increase the space occupied by the operating channel and aggravate instrument interference", this patent innovatively and non-obviously sets the suction channel of the suction device 2 and the body of the neuroendoscopy 1 in parallel, replacing the external combination / binding method of the prior art. The integrated structure greatly reduces the space occupied by the operating channel, and the guide structure standardizes the movement path of the suction device 2, avoiding the collision and obstruction problems of multiple instruments operating in parallel. Even in deep and narrow surgical fields such as the intracranial cavity, instrument interference can be effectively reduced.

[0049] (vii) In response to the shortcomings of all the prior art documents that "only achieve basic cooperation and do not truly reduce reliance on manpower", this patent innovatively and non-obviously expands the functionality of the integrated structural design and the integrated suction control switch 6 and soft dissection structure 3 in the hand-held part, allowing the surgeon to complete the whole set of core operations of neuroendoscopy 1 observation, suction 2 suction and tissue dissection with one hand. It completely abandons the traditional two-person four-hand operation mode, and does not require an assistant to hold the suction device alone or cooperate in adjusting the instruments, saving surgical manpower. At the same time, the surgeon can independently control the timing and position of suction, avoid the rhythm deviation of multiple people cooperating, and improve the ability to handle emergencies during the operation.

[0050] (viii) In response to the defects of all prior art, namely "asynchronous suction port and endoscope lens, easy contamination of lens", this patent innovatively and non-obviously sets the suction port of suction device 2 and the lens of neuroendoscopy 1 in a similar surgical field area. Suction device 2 can be pushed, pulled and slid to adjust its position synchronously, which can accurately target bleeding points and tissue debris accumulation areas, remove contaminants in time, avoid contamination of neuroendoscopy 1 lens, eliminate the need to repeatedly wipe the lens to interrupt the operation rhythm, and ensure the clarity and stability of the surgical field.

[0051] This push-pull sliding neuroendoscopy 1 and suction device 2 system achieves advantages such as lens protection from contamination, reduced operating space, smooth close-up observation, and no need for an assistant through the fusion of endoscope and suction device 2, push-pull system, and soft dissection structure 3. Its innovative integrated structural design places the suction channel and endoscope body in parallel, ensuring that the suction port and endoscope lens are in a similar surgical field area, enabling coordinated observation and suction. The adjustable suction port at the front end can be flexibly adjusted in size and angle via the handle control device to ensure precise suction target. The suction control switch 6 integrated in the handle supports one-handed operation by the surgeon, simultaneously enabling the opening and closing of endoscopic observation and suction functions and intensity adjustment. At the same time, the push-pull sliding structure facilitates smooth movement of instruments within the body, while the soft dissection structure 3 reduces damage to surrounding nerves during tissue dissection.

[0052] First, the lens is protected from contamination. Because the suction port is precisely aligned with the target, bleeding points and tissue debris can be promptly removed, preventing contamination of the endoscope lens and ensuring a clear and stable surgical field, reducing operational delays or errors caused by blurred vision. Second, it effectively reduces the space required for operation. The integrated design combines the endoscope and suction device, which previously required separate operations, into one, reducing the space needed for the surgical passage. This is particularly suitable for areas with limited operating space, such as the intracranial region, improving the convenience and safety of the surgery. Third, it enables smooth and close-range observation. The push-pull sliding structure, combined with the soft dissection structure, allows instruments to more flexibly penetrate the surgical area. Surgeons can observe the lesion at closer distances and from multiple angles, providing strong support for precise operation. Most importantly, no assistant is needed. The surgeon can complete endoscopic observation and suction operations with one hand, reducing reliance on assistants, avoiding coordination errors that may occur with multiple surgeons, improving surgical efficiency, and reducing surgical risks caused by personnel coordination issues.

[0053] A rubber ring 10 is elastically fitted onto the body of the neuroendoscope; a sleeve 9 is used to pass through a semi-closed clamping structure 5, which is made of plastic with clamping force. A further technical solution of the present invention is that the clamping force of the semi-closed clamping structure 5 is insufficient to prevent the suction device from sliding. The soft dissection structure 3 is a hollow tube made of medical-grade silicone. Of course, the semi-closed clamping structure 5 can also be made of other materials, and it can also be integrally cast onto the body of the neuroendoscope.
