Quick change device for multi-channel endoscope accessories

Abstract

The invention discloses a quick change device for multi-channel endoscope accessories, and relates to the technical field of medical equipment, solving the technical problem of inconvenience in endoscope operation. The device comprises a base and an endoscope connector. The endoscope connector for being connected with an endoscope biopsy channel is mounted at the lower end of the base. The base isinternally provided with a main channel and a plurality of sub-channels, and a lower opening of the main channel is communicated with the endoscope connector. The upper end of each sub-channel is open. A lower opening of each sub-channel is connected to an upper opening of the main channel, so that the endoscope accessories can enter the main channel through the sub-channels. Two clamping wheelsare arranged in the base, and are symmetrically distributed on left and right sides of the main channel. Part of the body of each clamping wheel is extended into the main channel. The quick change device is used in combination with a digestive endoscope.

Description

technical field [0001] The invention relates to medical equipment technology, in particular to a technology of a fast exchange device for multi-channel endoscope accessories. Background technique [0002] Medical digestive endoscopes are used to observe the natural cavity of the digestive system. Complicated endoscopic treatment requires the use of endoscopic accessories such as biopsy forceps, injection needles, and high-frequency electric knife. These endoscopic accessories need to be biopsied by the endoscope The channel is pushed into the operating field of view. During the operation, it is often necessary to replace the accessories to complete operations such as hemostasis, stripping, and metal frame clamping. It often requires repeated in and out of the accessories and alternates. This operation requires one or two assistants to assist the surgeon to replace the accessories.

Problems solved by technology

[0002] Medical digestive endoscopes are used to observe the natural cavity of the digestive system. Complicated endoscopic treatment requires the use of endoscopic accessories such as biopsy forceps, injection needles, and high-frequency electric knife. These endoscopic accessories need to be biopsied by the endoscope The channel is pushed into the operating field of view. During the operation, it is often necessary to replace the accessories to complete operations such as hemostasis, stripping, and metal frame clamping. It often requires repeated in and out of the accessories and alternates. This operation requires one or two assistants to assist the surgeon to replace the accessories. The operation is time-consuming and labor-intensive, requiring high physical strength and technical proficiency of assistants, and often causes iatrogenic injury to the patient's mucosa caused by excessively pushing accessories

[0003] In addition, due to the poor sealing of the biopsy channel, when exchanging accessories, various body fluids and blood of the patient will flow out and splash through the biopsy channel, polluting the operating table, the skin of the operator, and even splashing into the eyes and mouth of the operator. Cause iatrogenic pollution and iatrogenic infection
