Problems solved by technology

[0007] The object of the present invention is to provide a laparoscopic extraperitoneal cavity visible balloon dilation device to solve the first problem proposed in the above-mentioned background technology. The currently used balloon dilation does not have a control component, and it cannot pass the control while inflating. Components observe and measure the expansion degree of the balloon; second, there is no component for rapid advancement to assist in passing through the tube, which is not conducive to the delivery of the tube; third, there is no component for detecting the integrity of the airbag, which is not conducive to safety protection

Abstract

The invention discloses an extraperitoneal cavity visible balloon dilatation device for a laparoscope, relates to the technical field of surgical auxiliary instruments, and solves the problems that currently used balloon dilatation is not provided with a control component, and the expansion degree of a balloon cannot be observed and measured through the control component during inflating. The extraperitoneal cavity visible balloon dilatation device for the laparoscope comprises a main penetrating pipe, an operation air bag is arranged outside the main penetrating pipe in a sealed and fused mode, and a through hole is formed in the main penetrating pipe and communicated with the operation air bag; a needle hole camera is arranged outside the main penetrating pipe and monitors the operation air bag, through the arrangement of a contrast air bag, a contrast display function is provided, when the operation air bag cannot be observed, the opening and closing degree of the operation air bag can be deduced according to the expansion degree of the installed contrast air bag, in the descending process of a lifting piece, a piston rod is pushed to input air in a piston cylinder into the operation air bag and the contrast air bag, the operation air bag and the contrast air bag are dilated in the same proportion, and the contrast accuracy can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of surgical auxiliary instruments, in particular to a laparoscopic extraperitoneal cavity visible balloon expansion device. Background technique [0002] Balloon dilatation is a surgical method. Laparoscopic surgery is to make several small incisions in different parts of the abdomen. Through these small incisions, tools such as a camera lens and a balloon are inserted, and the balloon is inflated by gas to operate inside organs such as blood vessels. Complete the surgery. [0003] After retrieval, for example, the patent with the publication number CN208625766U discloses an auxiliary instrument for abdominal surgery, specifically relates to a visual balloon dilator for separating the retroperitoneum, including a puncture tube, a tracheal tube, and an expansion balloon. The balloon dilator also includes a self-sealing device. One end of the puncture tube is connected to the self-sealing device, and the othe...
