Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a digestive endoscope auxiliary traction device. Background Art
[0002] With the development of medical technology and the improvement of social health literacy, people are paying more and more attention to health issues, and more and more people are beginning to undergo digestive endoscopy. Digestive endoscopy can detect early lesions through high-definition magnification, staining and other technologies, and can also perform precise endoscopic resection of lesions. After years of development, endoscopic resection technology has evolved from the simple endoscopic mucosal resection (EMR) of the past to endoscopic submucosal dissection (ESD), endoscopic submucosal tumor excision (ESE) and endoscopic full-thickness resection (EFTR), etc., especially ESD surgery has become the standard surgical method for early gastrointestinal tumors. Traditional ESD and its derivative surgeries require the use of a transparent cap at the front end of the endoscope to expose the submucosal layer or tumor capsule, but the transparent cap cannot clear the difficult areas that cannot be approached by the inner diameter. Therefore, traction technology can solve these problems to a certain extent. With the help of external forces, traction technology can fully expose the lesions and overcome the adverse effects of gravity. The patient does not need to change position. Currently, lesions are often exposed by pulling or pushing dental floss, but during use, it will be found that dental floss is sharp and can easily cause cuts to soft tissues, making deep operations impossible, which affects its applicability. Utility Model Content
[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the utility model is to provide a digestive endoscope auxiliary traction device, which avoids cutting during traction by setting a protective cover on the outside of the dental floss, thereby ensuring safe operation.
[0004] In order to solve the above technical problems, the technical solution provided by the utility model is: a digestive endoscope auxiliary traction device, comprising:
[0005] A handle assembly, the handle assembly comprising a grip, a connection seat and an outer tube, the grip is a hollow tube, one end of which is rotatably connected to the connection seat, the outer tube is plugged into a side of the connection seat away from the grip and communicated with the hollow portion of the grip, and a through groove communicating with the hollow portion is provided on the side wall of the grip;
[0006] A traction assembly, the traction assembly includes dental floss, a sheath and a pull ring, the dental floss is movably inserted in the outer tube, and one side of the dental floss extends to the outside of the handle through the through groove, the dental floss is provided with a protective sheath, and the protective sheath is connected to the pull ring at one end of the handle.
[0007] Preferably, the protective sleeve and the dental floss are configured to be interference fit.
[0008] Preferably, the length of the protective sleeve is equal to the length of the dental floss.
[0009] Preferably, the dental floss is cylindrical or flat.
[0010] After adopting the above structure, the utility model has the following advantages:
[0011] The present application arranges a protective sleeve on the side of the dental floss so that when it is put on the diseased tissue, the contact area with the diseased tissue can be increased, thereby avoiding the occurrence of dental floss cuts and ensuring the traction effect. The structure is simple and can be used with the harmony clamp to perform multi-angle traction, thereby facilitating full exposure of the lesion.
[0012] The above summary is for the purpose of description only and is not intended to be limiting in any way.
