Anti-leakage device and installation method of anti-leakage device

Abstract

The invention discloses an anti-leakage device and an installation method of the anti-leakage device; the anti-leakage device comprises a telescopic part, a sponge, a medical pasting film and a drainage tube; the sponge comprises an installation surface, an operation area surface and a side surface; an installation hole is formed in the installation surface; the operation area surface is used for being installed in an operation area in an attached mode; the telescopic part comprises an elastic adjusting part, a fixing part and an elastic telescopic part, and is provided with a through hole for installing a working channel; the fixing part comprises a lap joint surface and an attaching surface; the attaching surface is installed on the installation surface; the telescopic part can stretch out and draw back in the direction perpendicular to the installation surface and is installed in the installation hole; the medical pasting film comprises a lap joint part and an attaching part; the lap joint part is in lap joint with the lap joint surface in a sealed mode; the attaching part is attached to the side surface and the installation surface in a sealed mode; the first end of the drainage tube is inserted into the sponge through the side surface; and the second end of the drainage tube is used for being communicated with a negative pressure tube. According to the anti-leakage device and the installation method of the anti-leakage device provided by the invention, flushing water is prevented from entering an operation area; dryness of the operation area is guaranteed; and the probability of wound infection of a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of medical operations, and more particularly, to an anti-leakage device and an installation method for the anti-leakage device. Background technique [0002] With the development of minimally invasive spinal surgery in recent years, various minimally invasive techniques emerge in an endless stream. Minimally invasive surgical methods represented by transforaminal endoscopic technology are also developing rapidly. The preparations before the operation are as follows: First, spread the disinfection sheet on the operation area (the operation area is exposed); then, directly cover the operation area with an orthopedic film; finally, cover the outer layer of the orthopedic film with the brain film, so that The operation area is closed, thus forming double protection for the operation area. After the operation starts, the flushing water used continuously (the water inlet of the intervertebral foramina mirror wil...

Problems solved by technology

[0003] In the prior art, during intraoperative operation, the membrane around the wound is placed on the working channel (a metal channel inserted into the body, which penetrates into the surgical area from the skin to ensure that the instrument will not be affected by the surrounding tissue during the operation). When the surgical instrument is repeatedly operated, The above-mentioned patch is easy to be lifted, which leads to a decrease in the sealing of the operation area, and then causes the flushing water to seep into the operation area along the lifted film, causing pollution to the surrounding operation field and the operator
