Problems solved by technology

[0002] At present, when suturing patients in surgical operations, it is necessary to thread the suture thread into the suture needle, and then clamp the suture needle with needle holders for suture. Threading is required for each suture. Manual threading is inefficient and difficult to operate.
And due to the limitation of the surgical exposure space, it is difficult to successfully comp

Embodiment

[0028] Such as figure 1 Shown is a preferred embodiment of a facet joint suture threader of the present invention, which mainly includes a handle part, an extension part 4 and a clamping part connected in sequence. The handle part includes the shell 1 and the bionic ring 2 on the shell 1. The smooth design and layout of the ring conform to the bionic structure, and the grip is more comfortable, enabling long-term operation without fatigue.

[0029] The front end of the extension part 4 is provided with a clamping part for clamping soft tissue, and a threading needle 6 is pierced in the extension part 4, and a thread hook groove 7 is provided on the threading needle 6. There is a push needle mechanism for pushing out and pulling back the threading needle. When pushing out, the threading needle penetrates the soft tissue and hooks the suture into the hooking groove, and then hooks the suture back when pulling back.

[0030] Further, the handle part is provided with a clamping m...

specific Embodiment approach

[0050] When threading, first wrap the suture thread in the U-shaped harness groove 11 of the outer jaw 8, then hook the outer jaw 8 on the inside of the soft tissue (such as tendon, ligament) to be sutured, and place the inner jaw 9 on the outside of the soft tissue , and then press down on the near-end finger ring 3 to drive the inner jaw 9 to close to clamp the soft tissue, and at the same time drive the threading needle 6 to push out, pass through the waist hole 14 on the inner jaw 9 and the soft tissue into the U-shaped wire harness groove 11 for threading the needle into the hole 13, hook the suture in the U-shaped wire harness groove 11 into the thread hook groove 7, and finally loosen the proximal finger ring 3 (or actively pull it back), drive the threading needle 6 to retreat, and pull the suture thread from the soft tissue to the The side is pulled over (the belt thread passes through the soft tissue), and the inner jaw 9 is opened (relaxing the clamping) simultaneous...

Abstract

The invention discloses a small joint suture threader which comprises a handle part and an extending part on the front end of the handle part, a clamping part is arranged on the front end of the extending part and used for clamping soft tissue, a suture needle is arranged in the extending part, the suture needle is provided with a suture hooking groove, and a suture pushing mechanism is arranged on the handle part and used for pushing out and pulling back the suture needle, when the suture needle is pushed out, the suture needle penetrates through soft tissue and hooks a suture into the suturehooking groove, and then the suture is hooked back when the suture needle is pulled back. The suture threader of the invention is exquisite and smooth in overall structure, convenient to use and lowin cost, and due to the vertical thin extending structure, the incision is smaller, and suture is easier to operate. During threading, soft tissue is clamped through the clamping part, and then the soft tissue can be punctured and the suture can be hooked back through the push out and pull back of the suture needle, so that clamping of the soft tissue and suture threading can be operated synchronously and conveniently, and is very suitable for surgical threading operation with a very small space, and the surgical threading difficulty is greatly reduced.

Description

technical field [0001] The invention relates to a small joint suture threader, which belongs to the technical field of surgical instruments. Background technique [0002] At present, when suturing a patient in a surgical operation, it is necessary to thread the suture thread into the suture needle, and then clamp the suture needle with needle holders for suture. Threading is required for each suture, and manual threading is inefficient and difficult to operate. And due to the limitation of the surgical exposure space, it is difficult to successfully complete the threading process of the suture needle, especially in some small joints, which requires both soft tissue clamping and suture threading, which greatly increases the difficulty of the operation. Therefore, there have been many kinds of threaders to assist in the threading process, but the existing threaders still cannot be used in very small surgical sites for threading. Contents of the invention [0003] Purpose of...
