Description

Single-hand operated single-hole laparoscope

Technical Field

The utility model relates to the field of medical equipment, concretely relates to single-handed operation's haplopore inspection peritoneoscope.

Background

The existing single-hole laparoscope is provided with an axial tool channel for various surgical tools to pass through and an axial line channel for light-guide fibers and video signal transmission lines to pass through. The light guide fiber and the video signal conducting wire penetrate through a preset channel and are connected with a light source and a camera at the front end of the mirror body. In order to prevent the endoscope body from rotating due to the dead weight of a lead and the pulling action in the operation process so as to influence the diagnosis accuracy, the outer wall of the rear part of the endoscope body of the existing single-port laparoscope is provided with an L-shaped handle for an operator to hold in the operation process, so that the situation that the existing single-port laparoscope needs the operator to vacate one hand to hold the handle is determined, the weight of the laparoscope is increased, and other operation operations of the operator are limited.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: the single-hole examination laparoscope operated by a single hand is provided, so that the laparoscope can not rotate along with the traction and the dead weight of a guide wire during operation, an operator can complete laparoscope examination by the single hand, and the examination efficiency is greatly improved.

The utility model relates to a single-hand operated single-hole examination laparoscope, which comprises a laparoscope body, wherein an axial tool channel for various surgical tools to pass through and an axial line channel for light-guide fiber and video signal transmission line to pass through are arranged in the laparoscope body, a camera and a light source projection end for collecting images are arranged at the front end of the line channel, the front end of the light-guide fiber in the line channel is connected with the light source projection end, and the front end of the video signal transmission line in the line channel is connected with the camera; the method is characterized in that: the middle rear part in the mirror body is sequentially provided with a light guide fiber winder and a video signal conducting wire winder, wherein the light guide fiber penetrates from the side surface of the light guide fiber winder, the spiral is tightly wound on the surface of the light guide fiber winding rod, the light guide fiber winding rod is axially fixed in the light guide fiber winder through a first spiral spring, the other end of the light guide fiber penetrates out of the other side of the light guide fiber winder and then penetrates out of the mirror body to be connected with a light guide fiber switching port, the video signal conducting wire penetrates in from the side surface of the video signal conducting wire winder, the spiral is tightly wound on the surface of the video signal conducting wire winding rod, the video signal conducting wire winding rod is axially fixed in the video signal conducting wire winder through the spiral spring, the other end of the video signal conducting wire penetrates out of the other side of the video signal conducting wire winder and, is connected with the video signal transmission line adapter interface.

Through the proposal, the utility model provides a pair of one-hand operation's single-port inspection peritoneoscope has the advantage be: through the optical fiber winder and the video signal conduction line winder that are equipped with in the internal portion of mirror, make the tractive of outside wire in the operation process of diagnosis have very big allowance, the tractive action turns into the axial of optical fiber winding bar and video signal conduction line winding bar and rotates, and because volute spiral spring's setting, outside wire can be automatic withdrawal after being elongated, optical fiber, the video signal conduction line, the tractive to the wire when switching mouth dead weight and operator operate, can not make the mirror body twist reverse all, only can twist reverse inside winding bar, so the operator can this peritoneoscope of one-hand operation, and saved at mirror body externally mounted L shape handle, the physical demands of operator has been alleviateed, operator's efficiency of diagnosis has been improved, the degree of accuracy of the process of diagnosis has been guaranteed.

The utility model discloses the technology is subsidized by 2017 degree national science fund (serial number: 81770512, topic name: miR-145-lncRNA-ADD3 regulates and controls the mechanism research of network in biliary tract atresia fibrosis formation process) and 2018 degree Shenzhen Shanzhen Weishengjie "three projects" (serial number: SZSM201812055, topic name: university Louis Qiang professor infant department of general surgery clinical and basic team).
