Novel telescopic head structure for enteroscope

Abstract

A novel telescopic head structure for an enteroscope comprises a camera assembly and a light source used for providing illumination, and is further provided with a movable head, a micro air cylinder and a thin film sleeve; the camera assembly and the light source are arranged on the movable head; the micro air cylinder is arranged in a concave cavity in the end part of a hose; a telescopic rod ofthe micro air cylinder is connected with the movable head, and used for driving the movable head to do telescopic motion; the thin film sleeve is arranged on the outer wall of the hose in a sleeving mode; connecting wires are arranged at the two ends of the thin film sleeve respectively; the connecting wire close to one end of the movable head bypasses a gap between the movable head and the end part of the hose, and extends out of the hose through a wire containing cavity channel formed in the hose; a drug application cavity channel is also formed in the hose; and several drug application holes communicated with the drug application cavity channel are formed in the outer wall of the hose. According to the scheme in the invention, due to additional arrangement of the movable head, the thinfilm sleeve and the drug application cavity channel, the position of the camera assembly can be freely and finely adjusted under the condition that the hose does not need to be pulled; and meanwhile,inspection and drug application are synchronously carried out.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel retractable head structure for enteroscopes. Background technique [0002] As we all know, enteroscope is a kind of slender and bendable medical device, which mainly includes: image display part, handle part, hose, camera assembly, lighting assembly, etc. 1. The lighting component is sent into the intestinal tract to observe whether there is a lesion on the inner wall of the intestinal tract. At present, the use of colonoscopy is one of the main diagnostic methods used by doctors to check intestinal diseases. [0003] At present, except for the relatively expensive speculum capsule, the structure of the enteroscope used is relatively simple. Generally, a hose is used to drive the camera assembly and the lighting assembly to be inserted into the intestinal tract to check the patient's condition. Due to the imperfection of the existing design, There are also the fo...

Problems solved by technology

[0003] At present, except for the relatively expensive speculum capsule, the structure of the enteroscope used is relatively simple. Generally, a hose is used to drive the camera assembly and the lighting assembly to be inserted into the intestinal tract to check the patient's condition. Due to the imperfection of the existing design, There are also the following two problems: one, because the doctor will constantly adjust the position of the camera during the examination to find a suitable image acquisition angle so that the lesion image can be clearly taken, but due to the fixed connection between the camera and the lighting assembly and the hose , which leads to the need to constantly pull the hose for adjustment. Since the hose enters the body longer, the continuous adjustment of the hose will bring more pain and discomfort to the patient; After the situation, it needs to be pulled out in time, and then the doctor will administer the medicine according to the condition, and this process cannot be carried out synchronously
