Surgery fixture clip applier

Abstract

A surgery fixture clip applier comprises: a body (10) which has a triggering device, the triggering device having an actuation state and a releasing state; a nippling lever (20) extending from the body and forming a twine hook (30) at the far end far away from the body; a track (23) being axially fixed at the inner cavity of the nippling lever along the nippling lever and extending to the twine hook; a bracket (21) sliding along the track, being capable of disposing at least one surgery fixture and being connected to the triggering device; a push plate (22) being arranged in the cavity formed between the bracket and the track and sliding matching the bracket, the push plate being abutted against the surgery fixture and being moving with the movement of the bracket and pushing the surgery fixture to the twine hook when being moving along the track to the twine hook, and when the bracket is returned to the body along the track, the push plate doing not return or return for a preset distance with the bracket and then stop returning. The surgery fixture clip applier is able to realize stable clip applying without deformation and stagnation, greatly reduce the technology requirement and reduce the cost.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a surgical clip applier. Background technique [0002] During the existing surgical operation, surgical clamps are used to ligate some blood vessels, catheters, and other channels that need to be ligated, as well as human tissues. This kind of surgical clip is fired by a special surgical clip applier. A common surgical clip applier includes a shell with a trigger device, a slender rod connected to the shell, and a jaw at the end of the rod. . When in use, align the mouth of the pliers with the blood vessels and other tissues to be ligated, control the surgical clip applier to push the surgical clips to the mouth of the pliers, and then close the mouth of the pliers to deform the outer shell clamp, so as to achieve the ligation effect. [0003] And existing most clamping mechanism adopts spring as driving mechanism more, because the reasoning size in the spring compression relea...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing clamping mechanisms use springs as the driving mechanism. Due to the uneven size, excessive speed and poor stability of the spring during the compression and release process

During the pushing process, surgical clips often fall off, become loose, and are squeezed into the machine during the pushing process, resulting in deformation, so that they cannot be clamped effectively or cannot be used

In the surgical operation process, the use of surgical clips needs to be accurate and timely. If the above problems occur, it will seriously affect the success of the operation.

Although surgical clip appliers with other precise structures can achieve the above-mentioned purpose, the internal mechanical structure of this type of clip feeding equipment is often extremely complicated. The push rod used for feeding is made of plastic, and its dimensional accuracy, durability The requirements for grinding performance and lubricating performance are extremely high, and the current technology is difficult to meet, resulting in high cost, so it cannot meet the needs of the market
