[0002] Minimally invasive surgery refers to a surgical method that uses minimally invasive surgical robots and related equipment to perform surgery inside the human body cavity. Compared with traditional surgical methods, minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery.

[0003] The surgical instrument is an important part of the surgical robot, including a transmission box, an instrument rod and a linkage joint. The first end of the instrument rod is in transmission cooperation with the transmission box, and the second end of the instrument rod is connected to the linkage joint. The transmission box can drive the instrument rod to move. The transmission box can be provided with a linkage rope, so that the linkage joint can be driven by the linkage rope to improve the flexibility of the surgical instrument.

[0004] However, during the assembly process of the surgical instrument, the linkage rope needs to be connected to the linkage joint and a certain pulling force is applied to the linkage rope. However, the assembly process of the linkage rope is cumbersome and the assembly efficiency of the surgical instrument is low. Summary of the invention

[0005] The embodiment of the present application provides a surgical instrument assembly tool to solve the problem that the assembly process of the linkage rope of the surgical instrument is complicated, resulting in low assembly efficiency of the surgical instrument.

[0006] The present application provides a surgical instrument assembly tool, comprising a base plate, a first fixing component, a second fixing component and a tensioning member;

[0007] The first fixing assembly is disposed on the base plate, and the first fixing assembly is used to fix at least one of the instrument rod and the transmission box;

[0008] The second fixing component is arranged on the base plate and is spaced apart from the first fixing component along the first direction, and the second fixing component is at least used to fix the snake bone connected to the instrument rod;

[0009] The tensioning member is at least used to be connected to one end of the linkage rope away from the linkage joint, so as to apply tension to the linkage rope.

[0010] By setting a base plate, a stable platform can be provided to ensure that the first fixed component and the second fixed component can operate on a fixed reference plane, thereby improving the stability of the assembly. The first fixed component and the second fixed component are both arranged on the base plate. By fixing the instrument rod, the transmission box and the snake bone respectively by the first fixed component and the second fixed component, it can be ensured that the key components of these surgical instruments maintain the correct positioning and direction during the assembly process, reduce assembly errors, and improve assembly accuracy. The tensioning member applies tension to the linkage rope to ensure that the linkage rope maintains appropriate tension during the assembly process, thereby improving the efficiency and accuracy of power transmission. It can be seen that the surgical instrument assembly tooling provided in the embodiment of the present application simplifies the assembly process through the synergistic effect of each component, helps to reduce the complexity and errors of manual operation, and improves assembly efficiency and the performance of surgical instruments.

[0011] As an optional implementation, at least one of the first fixing component and the second fixing component may be movably disposed on the substrate, so that the first fixing component and the second fixing component may be moved closer to or farther from each other along the first direction.

[0012] By setting at least one of the first fixing component and the second fixing component to be movable, the distance between the first fixing component and the second fixing component can be adjusted according to the specific installation requirements of the instrument to accommodate surgical instruments of different sizes and types. This adjustability improves the versatility and adaptability of assembly, reduces the need for special assembly tools, and saves production costs.

[0013] As an optional implementation, the substrate is provided with a sliding groove, and the sliding groove extends along the first direction;

[0014] The second fixing component is provided with a sliding block, and the sliding block can be movably arranged in the sliding groove. The second fixing component can approach or move away from the first fixing component along the first direction.

[0015] By setting a sliding groove and setting a sliding block on the second fixed component, the sliding groove can provide a clear guide path, and the cooperation between the sliding block and the sliding groove enables the second fixed component to move smoothly on the substrate. In this way, the friction and error during the movement of the second fixed component are reduced, and the accuracy and controllability of the movement are ensured. By allowing the second fixed component to move along the first direction, the assembly tooling can be adjusted according to the specific needs of the surgical instrument. This adjustment capability improves the versatility and flexibility of the assembly, can better support the assembly process of surgical instruments of different types and specifications, and reduces the dependence on special tooling.

[0016] As an optional implementation, the sliding block is provided with a locking piece, the locking piece is passed through the sliding block, and the sliding block is fixed to the base plate via the locking piece.

[0017] By setting a locking piece, the sliding block can be fixed to the base plate after it moves to the desired position, ensuring that the sliding block can remain stable after adjustment, so that the relative position of the first fixed component and the second fixed component remains stable and will not move due to external force or vibration, thereby maintaining the accuracy of assembly. Such a setting enhances the stability and reliability of the assembly tooling, ensuring that during the assembly process, the various components of the surgical instrument can maintain their predetermined positions, and achieving high-precision and high-efficiency assembly operations.

[0018] As an optional implementation, at least one of the first fixing assembly and the second fixing assembly includes a base and a cover plate;

[0020] At least one of the base and the cover plate is provided with a receiving groove, the receiving groove extends along the first direction, and the receiving groove is at least used to receive the snake bone.

[0021] With such a configuration, the combination of the base and the cover plate can provide an openable and closable structure, which is convenient for placing and fixing the instrument parts during the assembly process. The mobility of the cover plate allows the operator to conveniently open the cover plate to place or adjust the instrument parts during the assembly process, and then close the cover plate to fix the parts, which helps to simplify the assembly operation and improve assembly efficiency. The receiving groove provides a special space to accommodate the snake bone or instrument rod of the surgical instrument, and the design of the receiving groove extending along the first direction matches the placement direction of the snake bone or instrument rod, which helps to ensure that the snake bone or instrument rod can be accurately positioned and fixed during the assembly process.

[0022] As an optional implementation, the receiving groove is located on the base;

[0023] The receiving groove is adapted to the snake-bone shape.

[0024] By setting the receiving groove on the base, a stable foundation is provided to ensure that the snake bone can be firmly supported during the assembly process. The receiving groove is adapted to the shape of the snake bone, and the bent snake bone can be automatically straightened when it is located in the receiving groove, and the snake bone can be kept in a predetermined direction during the straightening process, achieving a better fixing effect and improving the reliability of assembly.

[0025] As an optional embodiment, the cover plate is provided with an observation portion, the observation portion faces the receiving groove, and the observation portion is at least used to observe the snake bone in the receiving groove.

[0026] In this way, the observation part can provide a non-invasive observation method, allowing the operator to view the internal situation without affecting the assembly process. The observation part facing the receiving slot can ensure that the operator can directly observe the state of the snake bone inside the receiving slot, so as to make adjustments and corrections during the assembly process. By observing the state of the snake bone in real time, the operator can better control the assembly process and ensure that the various components of the surgical instrument maintain the correct positioning and tension, thereby ensuring the accuracy and final performance of the surgical instrument after assembly.

[0027] As an optional implementation, a connecting structure is further provided between the base and the cover plate;

[0028] The connecting structure includes a matching fixed hook and a movable part;

[0029] The fixing hook is fixedly connected to the cover plate, and the fixing hook is provided with a fixing groove away from the base;

[0030] The movable part is rotatably arranged on the base; the movable part includes a connecting rod, and when the connecting rod is located in the fixing groove, the base and the cover plate are fixed by the connecting structure.

[0031] By setting up a connecting structure, the cover can be firmly fixed on the base, ensuring that the cover will not be accidentally opened or moved during the assembly process, thereby improving the stability and safety of the assembly. The connecting structure consists of a fixed hook and a movable part, which cooperate with each other to achieve the connection. The cooperation between the fixed hook and the movable part provides a flexible and reliable connection method, which makes the cover easy to open when needed and can be firmly fixed when closed, thereby improving the flexibility and reliability of the assembly. The rotatable design of the movable part and the use of the connecting rod ensure the flexibility and reliability of the connection, and improve the convenience and stability of the assembly. Such a setting enhances the functionality and reliability of the assembly tooling, ensures efficient and accurate operation during the assembly of the surgical instrument, and improves the final performance and safety of the surgical instrument.

[0032] As an optional implementation, the movable member includes an elastic portion, a first end of the elastic portion is rotatably connected to the base, and a second end of the elastic portion is connected to the connecting rod;

[0033] When the connecting rod is located in the fixing groove, the elastic portion is in a stretched state, and the elastic portion is used to apply a pulling force to the connecting rod.

[0034] By providing an elastic portion, and the first end of the elastic portion being rotatably connected to the base, this connection method allows the elastic portion to rotate freely within a certain range, thereby adapting to different assembly requirements and improving adaptability and ease of operation during the assembly process. By connecting the elastic portion to the connecting rod, the elastic portion can directly affect the movement and position of the connecting rod, helping to ensure that during the connection process, the elastic portion can effectively apply force to keep the connecting rod in the correct position. When the connecting rod is inserted into the fixing groove, the elastic portion is stretched, and the stretched state of the elastic portion provides a continuous pulling force for the connecting structure, helping to ensure that the connecting rod remains stable in the fixing groove, preventing the connecting rod from accidentally falling off during use, and improving the reliability of the connection between the cover plate and the base, thereby ensuring effective fixation of the snake bone and the instrument rod.

[0035] As an optional implementation, the tensioning member is provided with a hook portion;

[0036] The tensioning member is connected to the linkage rope through the hook portion so that the gravity of the tensioning member applies tension to the linkage rope.

[0037] By providing a hook portion, a simple and effective connection method is provided, so that the tensioning member can be firmly connected to the driving rope, ensuring that the tensioning member can effectively apply tension, and improving the stability and reliability of the connection.

This connection method simplifies the assembly process, facilitates the rapid connection and disassembly of the tensioning member, improves the convenience of operation, and ensures that the tensioning member can continuously apply tension. By utilizing the gravity of the tensioning member to apply tension, a tensioning mechanism that does not require additional power is provided. The tensioning mechanism utilizes the constancy of gravity to ensure that the driving rope always maintains appropriate tension, reduces the complexity of the assembly process, improves the operational convenience and reliability of the assembly tooling, and helps to ensure that efficient and precise operations can be achieved during the assembly of surgical instruments.

[0068] Unless otherwise stated, the term "plurality" means two or more.

[0069] As can be seen from the background technology, minimally invasive surgery refers to a surgical method that uses a minimally invasive surgical robot and related equipment to perform surgery inside a human body cavity.

[0070] Surgical instruments are an important part of surgical robots. Figure 1 As shown, the surgical instrument may include a transmission box 91, an instrument rod 92 and a linkage joint 94. The transmission box 91 is the power and control center of the surgical instrument. The transmission box 91 may be provided with a motor and a transmission mechanism, etc., for converting external input energy (such as electrical energy) into mechanical energy, thereby driving the movement of the entire surgical instrument.

[0071] The instrument rod 92 is a bridge connecting the transmission box 91 and the linkage joint 94, and is usually set to a slender structure so that it can shuttle in a narrow surgical space. The first end of the instrument rod 92 is in transmission cooperation with the transmission box 91 to ensure stable transmission of power. The second end of the instrument rod 92 is connected to the linkage joint 94, which can transmit the power and movement of the transmission box 91 to the surgical site.

[0072] The linkage joint 94 is the end effector of the surgical instrument and directly participates in the surgical operation. The linkage joint 94 can be used to clamp, cut or suture tissues through various surgical tools (such as forceps, scissors, tweezers, etc.).

[0073] A snake bone 95 may be connected between the second end of the instrument rod 92 and the linkage joint 94, and the snake bone 95 has a connecting and guiding function. The snake bone 95 is usually composed of a series of interconnected joints, which can bend and twist in multiple directions, thereby giving the surgical instrument higher flexibility and adaptability.

[0074] The transmission box 91 can be connected by a linkage rope 93 ( Figure 1 The linkage rope 93 is connected to the linkage joint 94. One end of the linkage rope 93 is connected to the transmission box 91, and the other end passes through the instrument rod 92 and the snake bone 95, and finally connected to the linkage joint 94. The transmission box 91 transmits power to the linkage joint 94 through the linkage rope 93. By controlling the tension and moving direction of the linkage rope 93, the linkage joint 94 can be accurately controlled.

[0075] When assembling the surgical instrument, aligning the snake bone 95 and pre-tensioning the linkage rope 93 inside the surgical instrument are important steps in the assembly process.

[0076] Among them, straightening the snake bone 95 can ensure that it can maintain stable bending and torsion performance in subsequent use, thereby improving the accuracy of surgical operations. The tight linkage rope 93 can more effectively transmit tension or thrust. Pre-tensioning the linkage rope 93 can tighten the linkage rope 93 to ensure the efficiency and accuracy of power transmission.

[0077] At present, during the assembly process of the surgical instrument, the snake bone 95 needs to be manually aligned, and the linkage rope 93 needs to be manually connected to the linkage joint 94, and a certain tension needs to be applied to the linkage rope 93. The operator needs to carefully align the various components to ensure the accurate connection between the linkage rope 93 and the linkage joint 94, and also needs to pay attention to controlling the tension of the linkage rope 93 and the alignment of the snake bone 95. These operation steps are cumbersome and complicated, resulting in low assembly efficiency of the surgical instrument, and prone to errors, which affect the performance of the surgical instrument.

[0078] Therefore, the embodiment of the present application provides a surgical instrument assembly tool, including a base plate 100, a first fixing component 200, a second fixing component 300 and a tensioning member 400. The first fixing component 200 and the second fixing component 300 respectively fix the instrument rod 92, the transmission box 91 and the snake bone 95, thereby ensuring that the key components of these surgical instruments maintain the correct positioning and direction during the assembly process, reducing assembly errors and improving assembly accuracy. The tensioning member 400 applies tension to the linkage rope 93 to ensure that the linkage rope 93 maintains appropriate tension during the assembly process, thereby improving the efficiency and accuracy of power transmission. In summary, the surgical instrument assembly tool provided in the embodiment of the present application simplifies the assembly process through the synergistic effect of each component, reduces the complexity and errors of manual operation, helps to improve assembly efficiency, and ensures the performance of surgical instruments.

[0079] The technical solution of the present application is described in detail below in conjunction with the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0080] Combination Figure 2 and Figure 3 As shown, an embodiment of the present application provides a surgical instrument assembly tool, including a base plate 100, a first fixing component 200, a second fixing component 300 and a tensioning member 400; the first fixing component 200 is arranged on the base plate 100, and the first fixing component 200 is used to fix at least one of the instrument rod 92 and the transmission box 91; the second fixing component 300 is arranged on the base plate 100, and is spaced apart from the first fixing component 200 along the first direction, and the second fixing component 300 is at least used to fix the snake bone 95 connected to the instrument rod 92; the tensioning member 400 is at least used to be connected to one end of the linkage rope 93 away from the linkage joint 94 to apply tension to the linkage rope 93.

[0081] It can be understood that the base plate 100 is the basic structure of the entire assembly tool, which is used to support and connect the first fixing component 200 and the second fixing component 300. The base plate 100 can provide a stable platform to ensure that the first fixing component 200 and the second fixing component 300 can operate on a fixed reference plane, thereby improving the stability of the assembly.

[0082] The first fixing component 200 is disposed on the base plate 100. By fixing the instrument rod 92 and the transmission box 91, the first fixing component 200 can ensure that these components maintain a stable positioning during the assembly process, reduce assembly errors caused by component movement, and improve assembly accuracy.

[0083] It should be noted that the first direction is Figure 2 The direction indicated by the middle arrow A is parallel. When the surgical instrument is placed on the surgical instrument assembly tool, the extension direction of the instrument rod 92 and the snake bone 95 is parallel to the first direction.

[0084] The second fixing assembly 300 is also disposed on the base plate 100 and is spaced apart from the first fixing assembly 200 along the first direction. The second fixing assembly 300 can fix the snake bone 95, which helps to straighten the snake bone 95 and promotes the snake bone 95 to be in a straight state, so as to ensure the stability and flexibility of the snake bone 95 during use.

[0085] During specific operations, the snake bone 95 can be set in the second fixing component 300, and the end of the instrument rod 92 away from the snake bone 95 can be set in the first fixing component 200. The instrument rod 92 and the snake bone 95 are fixed respectively by the first fixing component 200 and the second fixing component 300, which can ensure that the key components such as the instrument rod 92 and the snake bone 95 maintain the correct positioning and direction during the assembly process, which helps to reduce assembly errors and improve assembly accuracy.

[0086] One end of the linkage rope 93 away from the linkage joint 94 can be arranged on the transmission box 91 and extend to the outside of the transmission box 91. The tensioning member 400 is connected to the linkage rope 93 located outside the transmission box 91. During the assembly process of the surgical instrument, the tensioning member 400 applies tension to the linkage rope 93 to pre-tension the linkage rope 93, which can ensure the consistency of the pre-tightening of the linkage rope 93, so that the linkage rope 93 generates appropriate and consistent tension, avoids errors that may be caused by manual operation, helps to improve the efficiency and accuracy of power transmission of the surgical instrument, and ensures accurate control of the linkage joint 94.

[0087] It can be seen that the surgical instrument assembly tool provided in the embodiment of the present application can achieve efficient assembly of the linkage rope 93 through the coordinated action of the first fixing component 200, the second fixing component 300 and the tensioning member 400, while also achieving the straightening effect of the snake bone 95, thereby simplifying the assembly process, reducing the complexity and errors of manual operations, and improving the assembly efficiency and the performance of the surgical instrument.

[0088] In some embodiments, at least one of the first fixing assembly 200 and the second fixing assembly 300 may be movably disposed on the substrate 100 , so that the first fixing assembly 200 and the second fixing assembly 300 may move closer to or farther from each other along a first direction.

[0089] By setting at least one of the first fixing assembly 200 and the second fixing assembly 300 to be movable, the distance between the first fixing assembly 200 and the second fixing assembly 300 can be adjusted according to specific instrument requirements to accommodate surgical instruments of different sizes and types. This adjustability improves the versatility and adaptability of assembly, reduces the need for special assembly tools, and saves production costs.

[0090] In specific implementation, the user can adjust the distance between the first fixing assembly 200 and the second fixing assembly 300 according to the specific size of the instrument rod 92 and the snake bone 95, so that the second fixing assembly 300 always corresponds to the snake bone 95 of the surgical instrument, and the first fixing assembly 200 can correspond to the end of the instrument rod 92 away from the snake bone 95. In this way, a more effective fixing and supporting effect can be provided for the instrument rod 92 and the snake bone 95, so that the instrument rod 92 and the snake bone 95 can maintain proper positioning during the assembly process.

[0091] Combination Figure 2 and Figure 3 As shown, in some embodiments, the substrate 100 is provided with a sliding groove 110, which extends along a first direction; the second fixing component 300 is provided with a sliding block 310, which can be movably disposed in the sliding groove 110, and the second fixing component 300 can approach or move away from the first fixing component 200 along the first direction.

[0092] It can be understood that the sliding groove 110 can provide a clear guiding path, and the sliding block 310 is a structure connected to the second fixing component 300 and can move in the sliding groove 110 .

[0093] The cooperation between the sliding block 310 and the sliding groove 110 enables the second fixing component 300 to move smoothly on the substrate 100 , ensuring the accuracy and controllability of the movement, and facilitating the fine adjustment of the position of the second fixing component 300 .

[0094] By setting the second fixing component 300 as a movable part, when assembling the surgical instrument, it is only necessary to set the end of the instrument rod 92 away from the snake bone 95 on the first fixing component 200, and then adjust the position of the second fixing component 300 along the first direction based on the actual length of the instrument rod 92 so that the second fixing component 300 corresponds to the position of the snake bone 95. It has the characteristics of easy operation and can quickly fix the instrument rod 92 and the snake bone 95.

[0095] Combination Figure 4 As shown, in some embodiments, the sliding block 310 is provided with a locking member 320 , the locking member 320 is penetrated through the sliding block 310 , and the sliding block 310 is fixed to the substrate 100 via the locking member 320 .

[0096] A limiting portion 111 is provided at the bottom of the sliding groove 110 . The extending direction of the limiting portion 111 is consistent with the extending direction of the sliding groove 110 , and both are parallel to the first direction. The width of the limiting portion 111 is smaller than the slot width of the sliding groove 110 .

[0097] The locking member 320 includes a locking bolt 321 and a locking nut 322. The locking nut 322 is arranged in the limiting portion 111. The locking bolt 321 passes through the sliding block 310, and one end of the locking bolt 321 extends out of the sliding block 310 and extends into the limiting portion 111, and is connected to the locking nut 322 through threaded cooperation.

[0098] When the second fixing component 300 moves to a suitable position along the sliding groove 110, by rotating the locking bolt 321, the locking bolt 321 moves toward the locking nut 322 under the action of threaded cooperation, and the bolt head of the locking bolt 321 abuts against the surface of the sliding block 310, and the bolt head of the locking bolt 321 and the bottom wall of the sliding groove 110 clamp the sliding block 310 from the opposite side of the sliding block 310, thereby fixing the sliding block 310 and the substrate 100, thereby fixing the position of the second fixing component 300.

[0099] Specifically, the surgical instrument assembly tool provided in the embodiment of the present application provides a reliable fixing mechanism by setting a locking piece 320, so that the second fixing component 300 can be firmly fixed after adjustment, thereby reducing the assembly error caused by accidental movement of the second fixing component 300, and improving the stability and reliability of the surgical instrument assembly tool.

[0100] Combination Figure 5 and Figure 6As shown, in some embodiments, at least one of the first fixing component 200 and the second fixing component 300 includes a base 330 and a cover plate 340; the cover plate 340 is movably disposed on the base 330; at least one of the base 330 and the cover plate 340 is provided with a receiving groove 301, and the receiving groove 301 extends along the first direction, and the receiving groove 301 is at least used to accommodate the snake bone 95.

[0101] In some embodiments, the second fixing assembly 300 may include a base 330 and a cover plate 340. The combination of the base 330 and the cover plate 340 provides an openable and closable structure, which facilitates the placement and fixing of the snake bone 95 during the assembly process.

[0102] The receiving groove 301 provides a special space to accommodate the snake bone 95, and the extension direction of the receiving groove 301 matches the placement direction of the snake bone 95, ensuring that the snake bone 95 can be accurately positioned and fixed during the assembly process.

[0103] Exemplarily, the base 330 and the cover plate 340 may be provided with a receiving groove 301 on opposite sides. When the base 330 and the cover plate 340 are closed, the two receiving grooves 301 are located opposite to each other and are jointly surrounded to form a through hole capable of receiving the snake bone 95.

[0104] In specific implementation, the snake bone 95 can be placed in the receiving groove 301 on the base 330, and then the cover 340 is closed so that the receiving groove 301 on the cover 340 corresponds to the snake bone 95. At this time, the inner walls of the two receiving grooves 301 can press the snake bone 95, so that the bent snake bone 95 can be automatically straightened and restricted from moving.

[0105] In some embodiments, the first fixing assembly 200 may include a base 330 and a cover 340. The combination of the base 330 and the cover 340 provides an openable and closable structure, which facilitates the placement and fixing of the instrument rod 92 during the assembly process.

[0106] Exemplarily, the base 330 and the cover 340 are both provided with a receiving groove 301 on the opposite sides. When the base 330 and the cover 340 are closed, the two receiving grooves 301 are located opposite to each other and are jointly surrounded to form a through hole capable of receiving the instrument rod 92.

[0107] In a specific implementation, the instrument rod 92 can be placed in the receiving groove 301 on the base 330, and then the cover 340 is closed so that the receiving groove 301 on the cover 340 corresponds to the instrument rod 92. At this time, the through hole formed by the two receiving grooves 301 can limit the position of the instrument rod 92, thereby achieving a fixing effect on the instrument rod 92.

[0108] Combination Figure 5As shown, in some embodiments, the receiving groove 301 is located at the base 330; the receiving groove 301 is adapted to the shape of the snake bone 95.

[0109] The receiving groove 301 may be located on the base 330 of the second fixing assembly 300 and disposed on a side of the base 330 facing the cover plate 340 .

[0110] Exemplarily, the receiving groove 301 may have two side walls that are arranged opposite to each other, and the side walls extend along the first direction; in the direction away from the bottom surface of the receiving groove 301, the distance between the two side walls gradually increases.

[0111] The two side walls of the receiving groove 301 provide lateral support for the snake bone 95, ensuring that the snake bone 95 can be maintained in a predetermined direction during the straightening process.

[0112] In the direction away from the bottom surface of the receiving groove 301, the distance between the two side walls gradually increases, and the receiving groove 301 forms a conical or trapezoidal notch, so that the snake bone 95 is easier to put into the receiving groove 301 and is better fixed in the groove.

[0113] Correspondingly, the receiving groove 301 is also arranged on the cover plate 340 of the second fixing assembly 300 , and the receiving grooves 301 on the base 330 and the cover plate 340 are arranged relatively to each other to fix and align the snake bone 95 together.

[0114] Combination Figure 6 As shown, in some embodiments, the receiving groove 301 is located on the base 330 and the cover 340 of the first fixing component 200, the receiving grooves 301 on the base 330 and the cover 340 are arranged opposite to each other, and the cross-section of the receiving groove 301 perpendicular to the first direction is arc-shaped.

[0115] The arc-shaped receiving groove 301 can be well matched with the instrument rod 92, so that the fixing rod can be firmly placed and fixed during the assembly process.

[0116] In some embodiments, the cover plate 340 is provided with an observation portion, which faces the receiving groove 301 and is at least used to observe the snake bone 95 in the receiving groove 301 .

[0117] By setting up the observation part, a non-invasive observation method can be provided, so that the operator can view the internal situation of the receiving groove 301 without affecting the assembly process, ensuring that the snake bone 95 remains correctly positioned, thereby achieving efficient and precise operation during the assembly process of the surgical instrument and improving the final performance and reliability of the surgical instrument.

[0118] Exemplarily, the cover 340 can be made of a transparent acrylic material, and the cover 340 as a whole forms an observation portion. The operator can observe the state of the snake bone 95 in the receiving groove 301 through the transparent cover 340 to ensure that the snake bone 95 is in a straight state in the installed surgical instrument.

[0119] In other embodiments, the cover plate 340 may be provided with an observation port communicating with the receiving groove 301 , and the observation port forms an observation portion through which an operator can directly observe the state of the snake bone 95 in the receiving groove 301 .

[0120] A transparent mounting piece may also be provided in the observation port, and the mounting piece forms an observation portion. The operator may observe the state of the snake bone 95 in the receiving groove 301 through the transparent mounting piece.

[0121] Combination Figure 5 and Figure 6 As shown, in some embodiments, a connecting structure 350 is further provided between the base 330 and the cover 340; the connecting structure 350 includes a matching fixed hook 351 and a movable part 352; the fixed hook 351 is fixedly connected to the cover 340, and the fixed hook 351 is provided with a fixed groove 3511 away from the base 330; the movable part 352 is rotatably provided on the base 330; the movable part 352 includes a connecting rod 3521, and when the connecting rod 3521 is located in the fixed groove 3511, the base 330 and the cover 340 are fixed by the connecting structure 350.

[0122] Exemplarily, one side of the base 330 and the cover 340 can be rotatably connected by a hinge or hinge mechanism, and the other side of the base 330 and the cover 340 are connected by a connecting structure 350. By setting one side of the base 330 and the cover 340 to be rotatably connected, a flexible movement method can be provided to facilitate the opening and closing of the base 330 and the cover 340. The connecting structure 350 provides a stable connection method so that the cover 340 can be firmly fixed on the base 330. This design ensures that the cover 340 will not be accidentally opened or moved during the assembly process.

[0123] The fixing hook 351 is firmly connected to the cover 340 , and through the cooperation between the fixing slot 3511 and the movable member 352 , a simple and effective fixing mechanism is provided to ensure that the cover 340 can be firmly fixed to the base 330 when closed.

[0124] The connection structure 350 further includes a mounting seat 353, through which the movable member 352 is connected to the base 330, and the movable member 352 can rotate relative to the mounting seat 353. The rotatable design of the movable member 352 allows it to be adjusted during the assembly process so as to align with the fixing groove 3511 of the fixing hook 351. This design improves the flexibility of the connection and ensures that the base 330 and the cover plate 340 can be connected and fixed quickly and accurately.

[0125] After the connecting rod 3521 is inserted into the fixing groove 3511, a stable connection is formed to ensure a secure fixation between the cover 340 and the base 330. This design provides a simple and effective locking mechanism to ensure that the cover 340 will not be accidentally opened during the assembly process.

[0126] In some embodiments, the movable part 352 includes an elastic part 3522, a first end of the elastic part 3522 is rotatably connected to the base 330, and a second end of the elastic part 3522 is connected to the connecting rod 3521; when the connecting rod 3521 is located in the fixed groove 3511, the elastic part 3522 is in a stretched state, and the elastic part 3522 is used to apply pulling force to the connecting rod 3521.

[0127] The first section of the elastic portion 3522 is rotatably connected to the mounting seat 353 , and the second end of the elastic portion 3522 is connected to the connecting rod 3521 .

[0128] Exemplarily, there may be two groups of movable members 352, and the two groups of movable members 352 may be symmetrically distributed at both ends of the connecting rod 3521. The elastic portion 3522 may be a spring or an elastic sleeve.

[0129] In specific implementation, the snake bone 95 or the instrument rod 92 is arranged in the receiving groove 301, the cover plate 340 is closed and the connecting rod 3521 is located in the fixing groove 3511, at which time the elastic part 3522 is extended, and a rebound force is stored inside, and the rebound force has a tendency to pull the connecting rod 3521 away from the fixing hook 351. Under the action of the rebound force, the connecting rod 3521 abuts against the fixing hook 351, so that the base 330 and the cover plate 340 have a tendency to approach each other, and the base 330 and the cover plate 340 can respectively abut against the side wall of the snake bone 95 or the instrument rod 92, and exert a certain pressure on the snake bone 95 or the instrument rod 92, so as to limit the movement of the snake bone 95 or the instrument rod 92 relative to the fixing assembly.

[0130] In addition, the resilience of the elastic portion 3522 can also promote the close connection between the connecting rod 3521 and the fixing hook 351 , thereby improving the connection stability between the base 330 and the cover plate 340 .

[0131] When the base 330 and the cover plate 340 are fixed by the connection structure 350, there may be a gap between the base 330 and the cover plate 340. Such a configuration allows the first fixing assembly 200 and the second fixing assembly 300 to be adapted to the snake bones 95 or instrument rods 92 of different outer diameters, thereby improving applicability.

[0132] Combination Figure 2 As shown, in some embodiments, the tensioning member 400 is provided with a hook portion 410 ; the tensioning member 400 is connected to the linkage rope 93 via the hook portion 410 so as to apply tension to the linkage rope 93 through the gravity of the tensioning member 400 .

[0133] The hook portion 410 provides a simple and effective connection method, so that the tensioning member 400 can be firmly connected to the linkage rope 93, ensuring that the tensioning member 400 can effectively apply tension.

[0134] The tensioning member 400 is connected to the linkage rope 93 via the hook portion 410 . This connection method simplifies the assembly process and facilitates quick connection and disassembly.

[0135] Using the gravity of the tensioning member 400 to apply tension to the linkage rope 93 is a passive tensioning method that does not require an additional power source. The constancy of gravity can be used to ensure that the linkage rope 93 always maintains appropriate tension, thereby improving assembly efficiency and reliability.

[0136] Exemplarily, the tensioning member 400 may be a weight. A weight of appropriate weight may be selected in combination with the pre-tightening force required by the linkage rope 93, so as to pre-tighten the tensioning member 400 in the surgical instrument by relying on the weight of the weight itself, so that the tensioning member 400 obtains a consistent and stable pre-tightening force.

[0137] In summary, the surgical instrument assembly tool provided in the embodiment of the present application can ensure that the key components of the surgical instrument maintain the correct positioning and direction during the assembly process, reduce assembly errors, and improve assembly accuracy by fixing the instrument rod 92, the transmission box 91, and the snake bone 95 respectively through the first fixing component 200 and the second fixing component 300. Through the design of the movable fixing component and the sliding groove 110, the surgical instrument assembly tool can adapt to surgical instruments of different sizes and types, reduce the demand for special assembly tools, and reduce production costs. By applying tension to the linkage rope 93 through the tensioning member 400, the appropriate tension of the linkage rope 93 can be maintained without the need for additional power, thereby improving the efficiency and accuracy of power transmission. The various components of the surgical instrument assembly tool work together to simplify the assembly process, reduce the complexity and errors of manual operation, and improve assembly efficiency and the performance and accuracy of surgical instruments.
