Description

Technical Field

[0001] The utility model relates to the technical field of needle holders, in particular to a spinal endoscope needle holder. Background Technique

[0002] During the process of treating patients with spinal endoscope surgery, a needle holder is needed for intracavitary suture.

[0003] In the prior art, a Chinese patent with the publication number CN219557423U discloses a needle holder for use under a digestive endoscope, which adopts the scheme of "including: a traction wire, a clamping part, a traction rod, and a clamping sleeve; the traction rod is inserted into the clamping sleeve, and the traction rod and the clamping sleeve can be clamped and limited; the traction wire is inserted into the clamping sleeve; one end of the traction wire is connected to the traction rod, and the other end is connected to the clamping part; the traction rod can pull the traction wire to drive the clamping part to clamp or release, so as to clamp or release an internal medicine suture needle by the clamping part". With this scheme, by setting the traction rod, the doctor can hold the clamping sleeve in one hand and drive the traction rod to slide with the thumb. After the suture needle is clamped by the clamping part, the traction rod is clamped and limited on the clamping sleeve. At this time, the doctor does not need to apply force, which reduces the burden of the doctor's surgery on the one hand, and is simple and convenient to operate on the other hand, improving the doctor's operation efficiency.

[0004] However, the above scheme still has some deficiencies. For example, during the actual use of this needle holder, when clamping and suturing the needle tip, it is necessary to frequently use the thumb to pull the traction rod to achieve repeated clamping and suturing of the needle tip, which makes the thumb of the operator bear a heavy load and is prone to soreness and fatigue after a long time, resulting in unstable clamping of the needle tip by the clamping part and affecting normal suturing.

[0005] In view of this, the utility model proposes a spinal endoscope needle holder. Content of the Utility Model

[0006] The purpose of the utility model is to provide a spinal endoscope needle holder to solve the defect of heavy operation load of the operator proposed in the above background technique.

[0039] Hollow cylinder 100

[0040] Clamping part 200, which is used to clamp the needle. The clamping part 200 includes a semi-cylindrical fixed block 201 fixed at the end of the hollow cylinder 100, and a semi-cylindrical clamping block 202 rotatably arranged at the end of the hollow cylinder 100. Corresponding tooth grooves 203 are provided on the opposite surfaces of the semi-cylindrical fixed block 201 and the semi-cylindrical clamping block 202. An L-shaped rod 204 is fixed at the end of the semi-cylindrical clamping block 202, and a rotation opening 205 for the L-shaped rod 204 to rotate is provided at the end of the hollow cylinder 100. A rotating shaft 206 is rotatably arranged on the inner wall of the rotation opening 205, and the L-shaped rod 204 is fixed on the surface of the rotating shaft 206

[0041] Operating part 300, the operating part 300 includes an operating sleeve 301 rotatably arranged on the outer surface of the end of the hollow cylinder 100 through two bearings, and an installation box 302 is fixed at the end of the operating sleeve 301

[0042] A rubber sleeve 303 is sleeved on the outer surface of the operating sleeve 301, effectively improving the comfort of the hand during long-term use by personnel. And a controller 304 is arranged on the outer surface of the operating sleeve 301, facilitating the automatic control of the needle holder

[0043] A driving assembly 400 for driving the semi-cylindrical clamping block 202 to open and close automatically. The driving assembly 400 includes a pulling rope 401 fixed on the end surface of the L-shaped rod 204, and a first motor 402 for driving the pulling rope 401 to be pulled.

[0044] An installation plate is fixed on the inner wall of the installation box 302, and the first motor 402 is fixed on the surface of the installation plate. A charging power supply 600 is also fixed on the surface of the installation plate, which can provide power for the charged device.

[0045] A pulling spring 403 is fixed on the inner wall of the end of the hollow cylinder 100. The other end of the pulling spring 403 is fixedly connected to the surface of the L-shaped rod 204. A guiding roller 404 for guiding the pulling rope 401 is arranged on the inner wall of the hollow cylinder 100. An elastic sealing cloth 405 is fixed on the inner wall of the rotating opening 205, and a sealing hole fixedly connected to the outer surface of the L-shaped rod 204 is formed on the surface of the elastic sealing cloth 405, preventing body fluid from entering the hollow cylinder 100.

[0046] A fixing column 406 is fixed on the inner wall of the installation box 302, and a connecting column 407 is slidably arranged on the outer surface of the fixing column 406. A cylindrical cavity for the fixing column 406 to slide is formed at the end of the connecting column 407, and the end of the pulling rope 401 away from the L-shaped rod 204 is rotatably connected to the end of the connecting column 407.

[0047] A flat cut is formed on the surface of the connecting column 407, and a straight rack 408 is arranged on the surface of the flat cut. A transmission gear roller 409 meshing with the straight rack 408 is fixed on the output end of the first motor 402.

[0048] In this embodiment, by setting the driving assembly 400, during the actual use of the needle holder, the hollow cylinder 100 can be passed through the spinal endoscope for use. When in use, when it is necessary to clamp the needle, the first motor 402 can be started through the controller 304 to drive the transmission gear roller 409 to rotate. The rotation of the transmission gear roller 409 drives the connecting column 407 to move to the right under the action of the straight rack 408, thereby driving the pulling rope 401 to pull the L-shaped rod 204, causing the L-shaped rod 204 to rotate counterclockwise around the rotating shaft 206, making the semi-cylindrical clamping block 202 rotate and abut against the semi-cylindrical fixing block 201, realizing effective clamping of the needle. At the same time, during the suture process, when it is necessary to loosen the needle, the first motor 402 can be started to reverse through the controller 304, so that the L-shaped rod 204 can rotate clockwise around the rotating shaft 206 under the action of the pulling spring 403, realizing the separation of the semi-cylindrical clamping block 202 from the semi-cylindrical fixing block 201, achieving the purpose of loosening the needle. Thus, the needle holder can automatically clamp and loosen the needle through the controller 304, providing great convenience for the operator and ensuring the stability when clamping the needle.

[0049] Example Two

[0050] Based on Example One, and different from Example One,

[0051] A spinal endoscope needle holder further includes,

[0052] A rotating assembly 500, which is used to drive the clamping portion 200 to rotate automatically. The rotating assembly 500 includes a second motor 501 fixedly arranged on the inner wall of the installation box 302 for driving the hollow cylinder 100 to rotate.

[0053] A driving gear disk 502 is fixedly arranged at the output end of the second motor 501, and a driven gear disk 503 meshing with the driving gear disk 502 is fixedly arranged on the outer surface of the end of the hollow cylinder 100

[0054] In this embodiment, by setting the rotating assembly 500, when the needle holder is actually in use and the clamped needle needs to be rotated, the second motor 501 can be started through the controller 304 to drive the driving gear disk 502 to rotate. The rotation of the driving gear disk 502 drives the driven gear disk 503 to rotate, drives the hollow cylinder 100 to rotate, and thus drives the clamping portion 200 to rotate, achieving the purpose of automatic needle rotation, avoiding the need to rely on the wrist force of the operator's hand, further reducing the burden on the operator, and having strong practicability.
