Abstract

The utility model provides a novel arthroscopic surgery suture grasping forceps, which comprises a forceps head, a hollow forceps rod, a control front handle and a control rear handle, wherein the forceps head can precisely and efficiently grasp a needed suture in vivo, draw out the suture from the body, tie a knot, and draw back the suture in vivo; the binding clip comprises a slender binding clip in an arc shape. The utility model discloses an arc binding clip is more long and thin than the square wire binding clip of grabbing of tradition, and the wire pincers of grabbing through the modified only can lead to anchor line and two bone lines, then carry out the tractive and go out to tie a knot outward and go back to lead to if internal sewing up and tie a knot, improve operation effect and time greatly grabbing these two lines.

Description

Novel wire grasping forceps for arthroscopic surgery

Technical Field

The utility model belongs to the technical field of the medical treatment, especially, relate to a novel arthroscopic surgery grabs line pincers.

Background

The common field of the wire grasping forceps comprises knee arthroscopic tibia intercondylar spine fracture fixation, the cutting of a suture can cause the suture to be cut off and tissues can not be completely attached due to the unsmooth traction process of the suture grasping wire woven by a ligament under the condition that normal saline in a joint cavity is saturated in the operation, the free tissues in the joint cavity can be more easily wound, and the problem of passing through a tibia tunnel is also solved.

At present, the arthroscopic surgery is advocated with precise minimally invasive surgery, the 4.5mm tunnel can not meet the clinical requirements at present, and the 2.4mm tunnel adopted at present can meet the fixing mode of smooth line grabbing and traction only by using thinner line grabbing pincers. At present, in the existing wire grabbing clamp, the position can be accurately found for carrying out accurate minimally invasive operation only by repeatedly grabbing, threading and knotting wires for many times in the using process, so that the expected operation time effect cannot be achieved.

In addition, the existing wire grasping forceps in the shoulder sleeve tearing operation of the shoulder arthroscope also have various problems, after the anchoring nail is fixed, the double bone wires need to be matched with the wire grasping forceps when passing through the suture hook, one double bone wire and one anchoring nail wire are grasped, wound, pulled out of the body, knotted and pulled back. The joint internal suture has more sutures and is difficult to accurately grab the required anchor wires, and other anchor wires can be substituted, so that the aims of high efficiency and accuracy of the operation are contradicted.

SUMMERY OF THE UTILITY MODEL

To the current situation of the prior art, the utility model provides a novel arthroscopic surgery wire grasping forceps, which solves the defects existing in the prior art.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: a novel arthroscopic surgery wire grasping forceps comprises a forceps head, a hollow forceps rod, a front control handle and a rear control handle, wherein the forceps head can precisely and efficiently grasp a needed suture in a body, pull the suture out of the body to be knotted and then pull the suture back into the body to be sutured nearby; the binding clip comprises a slender binding clip in an arc shape.

Preferably, the forceps mouth is provided with fine teeth for preventing slipping during pulling.

Preferably, the front control handle and the rear control handle are connected by adopting a mortise and tenon structure.

Preferably, the space between the front control handle and the rear control handle is designed by adopting human engineering conforming to the medium and small hand shape of Chinese.

Has the advantages that:

the arc-shaped binding clip of the utility model is thinner and thinner than the traditional square thread-grasping binding clip, the improved thread-grasping binding clip can only lead in the anchor thread and the double bone thread, then the two threads are grasped, pulled out, knotted outside the body and pulled back, and the suture and knot are made inside the body, thus greatly improving the operation effect and time; meanwhile, the forceps mouth is designed with thin teeth to prevent slipping during traction; the front and rear handles are controlled to adopt a more durable mortise-tenon joint structure; the distance between the front handle and the rear handle is smaller, the human engineering conforming to the middle and small hand shapes of Chinese people is adopted, and the fatigue feeling can be better reduced under the condition of long operation time.

Detailed Description

In order to further understand and appreciate the structural features and advantages of the present invention, preferred embodiments and the accompanying drawings are described in detail as follows:

a novel arthroscopic surgery thread grasping forceps comprises a forceps head 1, a hollow forceps rod 2, a control front handle 3 and a control rear handle 4, wherein the forceps head 1 can precisely and efficiently grasp a needed suture in vivo, draw out the suture from the body, tie a knot and then draw back the suture into the body nearby; the binding clip 1 comprises an arc-shaped elongated binding clip 5. Further concretely, the arc-shaped forceps head is thinner and thinner than the traditional square wire grasping forceps head, the improved wire grasping forceps can only guide in the anchor wire and the double bone wires, then the two wires are grasped, pulled out, knotted outside the body and pulled back, and the suture and knotting are carried out in the body, so that the operation effect and the time are greatly improved

Further, the jaw 5 of the present embodiment is provided with serrations for preventing slipping off during pulling.

Further, in the embodiment, the front control handle 3 and the rear control handle 4 are connected by a mortise and tenon structure, and are reliable and durable.

Further, in the embodiment, the space between the front control handle 3 and the rear control handle 4 is designed according to the ergonomics of the middle and small hand of Chinese people, and compared with the traditional wire grasping forceps, the space between the front and rear handles is smaller, so that the fatigue feeling can be better reduced under the condition of long operation time.
