Apex head of honeycomb structure, endoscope and manufacturing method of apex head

Abstract

The invention discloses an apex head of a honeycomb structure. The apex head is installed at the front end of a catheter of an endoscope and includes a multi-channel module base and a sleeve sleevingthe outer circumferential surface of the multi-channel module base, the multi-channel module base is of a cylindrical irregular body structure with multiple inward concave channels in outer circumferential surface, the sleeve is a hollow cylinder with the inner diameter matched with the outer diameter of the irregular body structure, when the sleeve sleeves the outer circumferential surface of themulti-channel module base, the inward concave channels and the sleeve form a plurality of closed channels with openings at both ends, and the closed channels with the openings at both ends at least comprise the instrument catheter installation channels for inserting instrument catheters and the camera module installation channels for installing camera modules. According to the apex head of the honeycomb structure, the processing technology of the apex head of the endoscope catheter is greatly simplified, the inner diameter of each closed channel with the openings at both ends is increased, the diameter of the front end surface of the apex head of the endoscope catheter can be greatly reduced at the same time, the water return performance of the endoscope can be greatly improved, and the apex head has high practical value.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a honeycomb structure tip head, an endoscope and a manufacturing method thereof. Background technique [0002] An endoscope is a medical detection device that integrates image sensors, optical lenses, light source lighting, and mechanical devices. It can enter the stomach through the mouth or enter the body through other natural channels for surgical treatment of lesions. The endoscope can be used to see lesions that cannot be seen on X-rays, so it is very useful for doctors. For example, with the help of an endoscope, doctors can observe ulcers or tumors in the stomach, observe the condition of stones in the ureter, etc., and formulate the best treatment plan accordingly. When in use, it is introduced into the organ to be detected, and the lesion site can be clearly imaged on the photosensitive element through a camera, etc., and the image is transmitted to the visual device ...

AI Technical Summary

Problems solved by technology

The present invention provides a device that can take both soft and hard parts into consideration, and can be assembled and disassembled quickly, so as to facilitate the disinfection of various parts, easy to insert the ureter, and can smoothly enter each renal calices, especially the lower calices, and can well observe the situation in the lower calices. A uretero-nephroscope with a bendable head end; it solves the problem that the ureteroscope in the prior art is difficult to insert into the ureter, cannot observe the situation in the lower cup well, and can effectively perform diagnosis and treatment, and at the same time, the components cannot be quickly assembled, disassembled and sterilized question

[0006] However, the apex head of the uretero-nephroscope of the prior art adopts integral molding to form holes such as a camera hole and a chip seat, and the prior art uses plastic (such as a polymer material) material to make the apex head, such The manufacturing process of the tip head is not only complicated, but also due to the need to ensure a certain wall thickness during processing, the inner size of the manufactured hole is limited, which affects the performance of the camera that can be placed, and the diameter of the front surface of the tip head also needs to meet certain requirements. Due to the size requirements of the uretero-nephroscope, the sheath ratio of the uretero-nephroscope is greatly reduced, which affects the water return performance of the uretero-nephroscope
