Description

Disposable endoscope group and endoscope device

The present invention relates to a disposable device suitable for use in medical equipment such as a colonoscopy device or other endoscopy devices, and capable of reducing intestinal wall perforation and damage during operation, as well as avoiding repeated use of bacterial infections and viral infections. Endoscope group and endoscope device.

Endoscopy devices such as colonoscopes and gastroscopes are medical devices that are widely used in the examination of the digestive tract such as the stomach and intestines of the human body. Taking the colonoscope 70 with a more complicated structure as an example, as shown in FIG. 11, it includes a large colonoscope assembly 71 and an operation module 72. The colonoscope assembly 71 has an image capturing unit 711, a steering mechanism 712, and a wire 713 , A fluid conduit 714 and a solid outer covering 715 covering the aforementioned components, the operation module 72 is connected to the rear end of the colonoscope assembly 71, the operation module 72 has a processing unit, a steering control element 721 and a display 722, etc. The colonoscope 70 can be extended into the large intestine of the human body by the colonoscope assembly 71, wherein gas can be injected into the large intestine through the fluid conduit 714 to expand the large intestine, so that the colonoscope assembly 71 can be advanced in the large intestine. In addition, the image capturing unit 711 of the colonoscope assembly 71 captures the image of the inner surface of the wall of the large intestine. The image data obtained by the image capturing unit 711 can be displayed on the display 722 after being processed by the processing unit. Inject water into the large intestine to clean the intestinal wall to facilitate the capture of intestinal wall images.

During the aforementioned inspection of the human large intestine using the colonoscope 70, as shown in FIGS. 11 and 12, since the human large intestine 60 has many bending parts 61, 62, 63, 64, when the colonoscope assembly is extended into In the large intestine of the human body, since the image capturing unit 711, the steering mechanism 712, the wire 713, the fluid conduit 714, etc. in the colonoscopy assembly 71 are shaped with a solid outer covering 715, each unit length of the colonoscopy assembly 71 can The bending angle is too small and the flexibility is insufficient. During the operation of the colonoscope assembly 71 extending into the rectum from the anus of the human body and continuing to turn along the bowel of the large intestine, the colonoscope assembly 71 will produce the wall of the colon, especially when the physician operates the colonoscope assembly 71 to bend toward the colon When it is advanced at a deep position, the colonoscope assembly 71 can easily push and press the colon wall of the large intestine. Therefore, there are many technical difficulties in the operation of the colonoscope 70 and the perforation of the bowel wall. risk.

According to statistics, the use of colonoscopy for human colon examination procedures, the incidence of bowel wall perforation caused by colonoscopy is about 3 to 5 per 1,000. Due to the high incidence of perforation of the intestinal wall, how to operate an endoscope device such as a colonoscopy to smoothly turn along the bend of the gastrointestinal tract and reduce the pushing and compression of the gastrointestinal tract is important in the current technical field of endoscope devices One of the research and development projects.
