Puncture outfit for laparoscope

Abstract

The invention discloses a puncture outfit for a laparoscope. The puncture outfit comprises a cap, a cannula seat, a puncture cannula, a limiting block, a rotary fixing device, a clamping block and an adjusting ring, the bottom of the cap is fixedly connected with the top end of the puncture rod, a first mounting groove is formed in the top end of the cannula seat, and the left side of the limiting block is fixedly connected with the left side in the first mounting groove; a sleeve sealing cap is fixedly connected with the sleeve seat in a clamped mode through the clamping block, the cover cap penetrates through the sleeve seat and the puncture sleeve through the puncture rod to be installed at the top end of the sleeve seat. According to the invention, the puncture outfit for the laparoscope is provided with the limiting block, wherein the clamping block is limited through the limiting block; therefore, the invention solves the problems that when the clamping block is mounted in the first mounting groove, the clamping groove cannot be quickly and accurately clamped and fixed with a clamping rod, so that the mounting trouble between the sleeve sealing cap and the sleeve seat is increased, the sleeve sealing cap and the sleeve seat cannot be mounted, the psychological pressure of an operator is increased, and the whole operation progress is influenced.

Description

technical field [0001] The invention relates to the technical field of trocars, in particular to a trocar for laparoscopy. Background technique [0002] The laparoscopic puncture device is a minimally invasive abdominal and pelvic surgery, which can be used in various minimally invasive surgical procedures. The ergonomic grip handle is comfortable to handle and excellent puncture controllability. It is used as an instrument or camera through a single incision access to the abdominal cavity to perform minimally invasive laparoscopic surgery, but when the existing laparoscopic trocar needs to take out a large sample, the large sample can only be taken out by rotating the sealing cap of the sleeve. During the rotation process, due to the operator's hand Sweat or water will cause slippage between the hand and the cannula sealing cap, which will cause the cannula to swing and shake, and cause instability to the operation. The surgical machinery is operated and processed, so that...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a laparoscopic puncture device for the deficiencies of the prior art, to solve the problem that the existing laparoscopic puncture device proposed in the above background technology needs to take out a larger specimen, and the Larger specimens can be taken out only when the sealing cap is used. During the rotation process, due to sweat or water on the operator's hand, the hand and the sealing cap of the cannula will slip, which will cause the cannula to swing and shake, and cause inconvenience to the operation. Stability, and the existing laparoscopic puncture device needs to be operated by different surgical machinery during the operation, so that the machinery with different diameter ranges penetrates the sealing pad, resulting in a decrease in the resilience of the sealing pad, which in turn causes external dust and Bacteria enter the human body through the sealing gasket, thereby increasing the problem of human wound infection
