These tools include but are not limited to dissectors, aspirators, irrigators, and brain pressure plates. However, existing dissectors are usually integrally formed, and the one-piece design limits the adaptability to different anatomical structures and surgical needs during surgery. In order to cope with various surgical situations, hospitals need to prepare multiple sets of one-piece dissectors of different specifications. There is also no good structural combination between the corresponding aspirators, irrigators, and brain pressure plates to reduce the difficulty of surgical operations and improve the success rate and fault tolerance of the operation.

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Parts not described herein are all implemented by conventional technical means in the art, so they will not be described in detail. Embodiment 1

[0022] The hyperbolic left-bend stripper 2 can be replaced by strippers of other structural shapes, such as Figures 6 to 14The hyperbolic right-bend stripper 3, right-bend stripper 4, left-bend stripper 5, ball-head straight stripper 28, ball-head curved stripper 29, round stripper 30, round angle stripper 31, straight spade-shaped stripper 32, spade-shaped curved stripper 33, etc. are shown. Each shape has its applicable surgical environment, such as the hyperbolic left-bend stripper 2 is used for operations that need to bypass multiple obstacles or go deep into narrow spaces, and its left-bend feature enables it to more easily reach the deep structure on the left side. The hyperbolic right-bend stripper 3 is used for operations that need to bypass multiple obstacles or go deep into narrow spaces, and can help doctors obtain better angles and fields of view when dealing with deep structures on the right side.

[0023] Preferably, the outside of the stripping handle 1 is made of insulating material, such as plastic material, and the end where the stripping handle 1 is connected to the stripper is provided with an internal connecting thread. Correspondingly, different types of strippers are made of metal material, and different types of strippers are provided with external connecting threads on the outside of the end where the stripping handle is connected. In this way, the outer end of the stripping handle 1 can be connected to different types of strippers, which is convenient for repeated disinfection and use of the strippers.

[0024] On this basis, the stripping handle 1 is provided with an electrical connection socket at the end away from the stripper, and the electrical connection socket can be connected to the stripper made of metal material through the wire 34 passing through the stripping handle 1 to form an electrical connection. In this way, the stripping component can be used to connect with the neuroelectrophysiological device. The paired stripping components can be respectively connected to the positive and negative poles of the neuroelectrophysiological device, and can be used for intraoperative nerve monitoring during stripping to further ensure the safety of the operation (the neuroelectrophysiological device is a common device and is not shown).

[0025] like Figure 1 As shown, the specific suction assembly includes an aspirator 22 and a suction head with a flat end. The suction head with a flat end can provide a large contact area, can remove a large amount of liquid in a short time, and keep the surgical field clear.

[0026] You can also Figure 2 As shown, a hole is provided on the side of the flat suction head at the end for sucking the tumor tissue for pulling. The size of the hole provided on the side can be set according to the actual situation and is not specifically limited. Suction components of different sizes can be provided to meet the actual needs of the operation. Generally, the tool of the corresponding size is selected before the actual operation.

[0027] like Fig.19 As shown, the specific flushing part is shown as the flushing device 27.

[0028] As a preference, the flushing member can be combined with the stripping member, as shown in FIG. Fig.21As shown, the stripper can be fixed on one side of the independent irrigator cannula 23 to achieve self-closing use. The irrigator cannula 23 can also be made of flexible or semi-flexible materials to facilitate the adjustment of the angle for use with the stripper. Specifically, in order to facilitate the replacement of the stripper, a sleeve 35 is provided on one side of the irrigator cannula 23. When in use, the stripper is loaded into the sleeve 35 and used in combination with the irrigator cannula 23. The sleeve 35 can also be made of a flexible or semi-flexible material with a certain elasticity. After use, it can be removed to facilitate the replacement of different types of strippers.

[0029] like Fig.18 , Fig. 20 As shown, the brain pressure plate assembly includes a brain pressure plate 25, and a plug-in tube 26 for the suction head and the irrigator 27 of the suction assembly to pass through. The length of the suction head and the irrigator 27 extending out can be controlled according to actual needs. The plug-in tube 26 is made of flexible rubber, and the left and right angles of the extended parts of the suction head and the irrigator 27 can be adjusted within a certain angle.

[0030] Through the above technical scheme, the hyperbolic left-bend stripper 2 is inserted into the slot 6, the connecting strip 21 is pulled and then the sliding column 15 and the sliding column 20 are pulled at the same time so that the block 11 and the block 2 17 slide into the limiting groove 14 and the limiting groove 2 19 respectively. At this time, one end of the hyperbolic left-bend stripper 2 pushes the slide plate 9 to squeeze the spring 18 inward until the limiting column 7 and one side of the slide plate 9 are against each other, and the connecting strip 21 is released. Under the reset action of the two springs 2 13 and the limiting action of the limiting plate 1 12 and the limiting plate 2 18, the block 11 is engaged with the slot 10, and the block 2 17 is engaged with the slot 2 16, thereby realizing the rapid assembly of the hyperbolic left-bend stripper 2 and the stripping handle 1, and facilitating the rapid disassembly and replacement of the hyperbolic left-bend stripper 2. The doctor can quickly replace the stripping heads of different shapes and sizes according to actual needs without frequently removing the entire tool, thereby reducing the time of surgical interruption and making the surgical process smoother.

[0031] Fix the brain pressure plate 25 to expose the surgical area, use the hyperbolic left-curved dissipator 2 to separate the tissue, pass the irrigator 27 through the insertion tube 26, provide sterile solution to the surgical area for flushing, remove the irrigator 27 from the insertion tube 26, pass the suction head on the aspirator 22 through the insertion tube 26, and bring the suction head on the aspirator 22 close to the surgical area to aspirate the fluid.

[0032] It should be noted that if Figure 1 , Figure 3 As shown, the suction device 22 is provided with a water drop-shaped operation port, and the doctor controls the suction force of the suction device 22 by the degree to which the thumb covers the operation port. Figure 4As shown, a suction force regulating slide is provided on the suction device 22, and the suction force is controlled by controlling the area covered by the regulating slide, thereby achieving quantitative and continuous suction, which facilitates the operation.

[0033] An operating method applicable to the above-mentioned brain surgery system comprises the following steps: S1, surgical preparation, sterilize the stripping handle 1, the stripper, the suction device 22 with a flat suction head end, the irrigator 27, the brain pressure plate 25, and the insertion tube 26 to a sterile state; S2, installing the brain pressure plate 25, connecting the brain pressure plate 25 to the metal arm on the head frame, and adjusting the position by the metal arm to expose the surgical area; S3, performing the stripping, installing the stripper 2 on the stripping handle 1, holding the stripping handle 1 and using the stripper to separate and remove the soft tissue; S4, perform suction, pass the suction device 22 through the insertion tube 26 and place the end of the suction device 22 close to the surgical area, suck out the liquid and loose tissue, and then remove the insertion tube 26; S5, perform flushing, insert the flusher 27 through the plug tube 26 and connect the flusher 27 to the flushing liquid hose, inject the flushing liquid into the surgical area, and remove the plug tube 26 after cleaning the surgical area; S6. Postoperative care: After the operation is completed, the peeling handle 1, the peeling element, the suction device 22 with a flat suction head end, the irrigator 27, the brain pressure plate 25, and the insertion tube 26 are cleaned and disinfected again to a sterile state.

[0034] The above steps, especially steps S3 to S5, do not have a corresponding order relationship, and the execution order can be adjusted according to actual needs. Among them, the stripper can adopt a variety of structural strippers, such as Figures 5 to 14 The hyperbolic left-curved stripper 2, the hyperbolic right-curved stripper 3, the right-curved stripper 4, the left-curved stripper 5, the ball-headed straight stripper 28, the ball-headed curved stripper 29, the round stripper 30, the round angle-curved stripper 31, the straight spade-shaped stripper 32, the spade-shaped curved stripper 33, etc. are shown. Each shape has its applicable surgical environment, such as the hyperbolic left-curved stripper 2 is used for operations that need to bypass multiple obstacles or go deep into narrow spaces, and its left-curved characteristics enable it to more conveniently reach the deep structures on the left side. The hyperbolic right-curved stripper 3 is used for operations that need to bypass multiple obstacles or go deep into narrow spaces, and can help doctors obtain better angles and fields of view when dealing with deep structures on the right side.

The hyperbolic right-bend stripper 3 is used for operations that need to bypass multiple obstacles or go deep into narrow spaces, and can help doctors obtain better angles and fields of view when dealing with deep structures on the right side.

[0038] Preferably, the outside of the stripping handle 1 is made of insulating material, such as plastic material, and the end where the stripping handle 1 is connected to the stripper is provided with an internal connecting thread.

[0040] like Fig.19 As shown, the specific flushing member is shown as a flushing device 27. As an example, the flushing member can be combined with a stripper, as shown in FIG. Fig.21 As shown, the stripper can be fixed on one side of the independent irrigator cannula 23 to achieve self-closing use. The irrigator cannula 23 can also be made of flexible or semi-flexible materials to facilitate the adjustment of the angle for use with the stripper.

[0045] Fix the brain pressure plate 25 to expose the surgical area, use the hyperbolic left-curved dissipator 2 to separate the tissue, pass the irrigator 27 through the irrigator cannula 23, provide sterile solution to the surgical area, and bring the suction head on the aspirator 22 close to the surgical area to efficiently aspirate the liquid through the suction hole 24 to achieve simultaneous flushing and aspiration, which can not only keep the field of view of the surgical area clear, but also maintain the moistness of the tissue, thereby improving the safety and effectiveness of the operation.

[0046] It should be noted that if Figure 1 , Figure 3 As shown, the suction device 22 is provided with a water drop-shaped operation port, and the doctor controls the suction force of the suction device 22 by the degree to which the thumb covers the operation port. Figure 4 As shown, a suction force regulating slide is provided on the suction device 22, and the suction force is controlled by controlling the area covered by the regulating slide, thereby achieving quantitative and continuous suction, which facilitates the operation.

[0047] An operating method applicable to the above-mentioned brain surgery system comprises the following steps: S1, surgical preparation, sterilize the peeling handle 1, the peeling piece, the aspirator 22 with a rounded end of the suction head, the irrigator 27, the brain pressure plate 25, and the plug tube 26 to a sterile state; S2, installing the brain pressure plate 25, connecting the brain pressure plate 25 to the metal arm on the head frame, and adjusting the position by the metal arm to expose the surgical area; S3, performing stripping, installing the stripper on the stripping handle 1, holding the stripping handle 1 and using the stripper to separate and remove the soft tissue; S4, perform suction, bring the suction hole 24 on the side wall of the end of the suction device 22 close to the surgical area, and suck out the liquid and loose tissue; S5, perform flushing, insert the flusher 27 through the flusher cannula 23 on the aspirator 22 and connect the flusher 27 to a flushing liquid hose, inject flushing liquid into the surgical area, and clean the surgical area; S6. Postoperative care: After the operation is completed, the peeling handle 1, the peeling piece, the suction device 22 with a flat suction head end, the irrigator cannula 23, the irrigator 27, the brain pressure plate 25, and the insertion tube 26 are cleaned and disinfected again to a sterile state.

[0048] The above steps, especially steps S3 to S5, do not have a corresponding order relationship, and the execution order can be adjusted according to actual needs. Among them, the stripper can adopt a variety of structural strippers, such as Figures 5 to 14 The hyperbolic left-curved stripper 2, the hyperbolic right-curved stripper 3, the right-curved stripper 4, the left-curved stripper 5, the ball-headed straight stripper 28, the ball-headed curved stripper 29, the round stripper 30, the round angle-curved stripper 31, the straight spade-shaped stripper 32, the spade-shaped curved stripper 33, etc. are shown. Each shape has its applicable surgical environment, such as the hyperbolic left-curved stripper 2 is used for operations that need to bypass multiple obstacles or go deep into narrow spaces, and its left-curved characteristics enable it to more conveniently reach the deep structures on the left side. The hyperbolic right-curved stripper 3 is used for operations that need to bypass multiple obstacles or go deep into narrow spaces, and can help doctors obtain better angles and fields of view when dealing with deep structures on the right side.
