[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 7 As shown, this embodiment discloses a surgical instrument handle, including a handle 1, a push rod 2, a first spring 3, a second spring 4, and a handle portion 5.

[0018] The handle portion 5 includes a handle body 51, a gripper 52, and a rod portion 53. The gripper 52 includes two spaced-apart elastic claws 54, which are connected to the rod portion 53, and the rod portion 53 is connected to the handle body 51. The handle portion is integrally molded and made of metal.

[0019] In the specific structure, the handle body 51 is provided with a first mounting hole 511 and a second mounting hole 512. The first mounting hole 511 is connected to the second mounting hole 512. The rear end of the handle body 51 is provided with an end cap 513 (connected to the handle body 51 by thread or interference fit) to close the second mounting hole 512. The second spring 4 is placed in the second mounting hole 512.

[0020] The central hole of the rod 53 connects to the gap between the two elastic claws 54, and the central hole of the rod 53 also connects to the first mounting hole; the push rod 2 is placed in the central hole of the rod 53, and a boss 21 is provided at the end of the push rod 2 away from the claw 52. The boss 21 is located in the second mounting hole 512 and abuts against the second spring 4. A push block 6 is sleeved on the part of the push rod 2 located in the first mounting hole 511. The first spring 3 is sleeved on the push rod 2 and its two ends abut against the push block 6 and the boss 21 respectively. Openings are provided on both sides of the handle 51, and the push block 6 partially protrudes from the openings on both sides of the handle 51.

[0021] The handle 1 includes a hinge part 11 and a pressing part 12. The hinge part 11 and the pressing part 12 are connected in an L-shape. The hinge part 11 is provided with an opening groove 13. The handle 1 is fitted onto the handle body 51 through the opening groove 13. A rotating shaft 7 is installed at the bottom of the handle body 51. The axial direction of the rotating shaft 7 is perpendicular to the length direction of the handle body 51. The two groove walls of the opening groove 13 of the handle 1 are respectively connected to the two ends of the rotating shaft 7. The two groove walls of the opening groove 13 abut against the part of the push block 6 exposed outside the handle body 51. The pressing part 12 is opposite to the handle body 51.

[0022] Preferably, the handle 1 is ergonomically designed. The pressing part 12 has a protrusion 8 on the side opposite to the handle body 51 near the hinge part 11. The protrusion 8 can block the user's hand, increase grip strength, and prevent slippage. In addition, the surface of the handle 1 is rounded to avoid hand discomfort and increase grip strength.

[0023] Preferably, the diameter of the rod 53 is smaller than the diameter of the handle 51, and the rod 53 is a small elongated cylindrical shape. The miniaturized design of the gripper 52 and the reduced diameter of the rod 53 relative to the diameter of the handle 51 eliminate obstruction of the field of vision during surgery.

[0024] Under normal conditions, the second spring 4 pushes the push rod 2 forward. The push rod 2, through the thrust of the boss 21 against the first spring 3, forces the push block 6 against the handle 1, causing the handle 1 to tilt relative to the handle portion 5. At this time, the front end of the push rod 2 inserts between the two elastic claws 54, forcing the gripper 52 to open. When it is necessary to clamp the surgical instrument, press the handle 1 to a stationary state. The handle 1 pushes the push block 6, which, by squeezing the first spring 3, moves the push rod 2 backward. The front end of the push rod 2 moves away from the gripper 52, reducing the gap between the two elastic claws 54, thereby clamping the surgical instrument.

[0025] When assembling the handle part 5, the push block 6 is inserted into the handle body 51 through the opening on the side of the handle body 51. Then, the push rod 2, which is fitted with the first spring 3, is inserted into the second mounting hole 512. The push rod 2 passes through the push block 6 (the push block 6 has a hole for the push rod 2 to pass through). Next, the second spring 4 is installed into the second mounting hole 512, and then the end cover 513 is put on. After removing the end cover 513, the push rod 2, push block 6, first spring 3, and second spring 4 can all be removed for cleaning. The central hole of the rod part 53 is connected to the gripper 52 and the inner hole of the handle body. That is to say, the handle part 5 adopts a through-type integrated design, which ensures that the push rod 2 can be smoothly inserted into the gripper 52 to open the gripper 52. At the same time, it can be used to thoroughly clean and disinfect the inside of the handle part 5 after surgery.

[0026] The surgical instrument handle provided in this embodiment has the following characteristics: 1. The design of the small, elongated cylindrical rod 53 at the front end of the handle part 5, combined with the miniaturized design of the functional area gripper 52, eliminates the problem of obstructed vision during the operation and avoids the problem of dryness of the micro-incision during unicompartmental knee surgery. 2. The handle 1 is ergonomically designed to increase grip strength; 3. Utilizing the elasticity of the metal grippers 52, the matching surgical instruments can be quickly installed and removed; 4. In clinical surgical procedures, the kit is designed to be compatible with various surgical instruments, meaning it can be used with all clampable instruments in the kit.

[0027] The above description is only a preferred embodiment of the present utility model. It should be understood that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
