[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] This utility model provides a spring-loaded scissors for neurosurgery. Please refer to [link / reference]. Figures 1-4It includes a first scissor arm 1 and a second scissor arm 2. The ends of the first scissor arm 1 and the second scissor arm 2 are respectively equipped with a first finger ring 13 and a second finger ring 21. The first scissor arm 1 and the second scissor arm 2 are hinged together by a pin. An auxiliary mechanism is installed on the second scissor arm 2. Under the action of the auxiliary mechanism, the tissue to be cut can be driven between the first scissor arm 1 and the second scissor arm 2, so that the tissue to be cut can be pulled up without the need for another hand to hold pliers or clamps.

[0024] The auxiliary mechanism includes a sliding rod 10 slidably connected to the second scissor arm 2. A steel wire rope 5 is fixedly connected to the end of the sliding rod 10. A support rod 3 is slidably connected to the steel wire rope 5. The end of the support rod 3 is welded to the first scissor arm 1. A ring 4 is fixedly connected to the end of the steel wire rope 5. A support block 111 is welded to the end of the sliding rod 10. A hook 11 is fixedly connected to the top of the support block 111. The hook 11 is located on the outside of the first scissor arm 1.

[0025] The second scissor arm 2 is welded with a stabilizing guide block 8. The stabilizing guide block 8 has a through hole for the sliding rod 10 to pass through. The sliding rod 10 passes through the through hole on the stabilizing guide block 8, and the inner wall of the stabilizing guide block 8 and the sliding rod 10 are slidably connected.

[0026] The second scissor arm 2 is fitted with a drive ring 12 and a spring 9. The drive ring 12 is welded to the sliding rod 10, and the spring 9 is located between the drive ring 12 and the stabilizing guide block 8. The elastic force of the spring 9 can drive the hook 11 to reset.

[0027] A connecting ring 7 is welded to the end of the sliding rod 10, and the connecting ring 7 is fixedly connected to one end of the wire rope 5.

[0028] It also includes a guide block 6 welded to the bottom of the second scissor arm 2. The guide block 6 has a through hole for the wire rope 5 to pass through, and the through hole on the guide block 6 is coaxially distributed with the sliding rod 10. The wire rope 5 passes through the through hole on the guide block 6. The guide block 6 ensures that the part of the wire rope 5 near the stable guide block 8 is coaxially distributed with the sliding rod 10, thereby making the movement of the sliding rod 10 smoother.

[0029] In practical use, the thumb and middle finger are passed through the second ring 21 and the first ring 13, and the hook 11 is used to hang the cut tissue (blood vessels, nerves, etc.).

[0030] Insert your index finger through the ring 4 and control the ring 4 to move it. This will drive the sliding rod 10 to move via the wire rope 5, which in turn moves the hook 11 until the tissue to be cut is moved between the first scissor arm 1 and the second scissor arm 2, where the cutting operation will be performed.

[0031] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
