Transurethral bendable manual cystoscope

Abstract

The invention relates to a transurethral bendable manual cystoscope, comprising a cystoscope body and a three-degree-freedom driving unit; the cystoscope comprises a high definition camera with a lighting module, a fixing disk, two first structure bones, a second structure bone, a supporting component and a thin wall pipe with a circular section, wherein two first structure bones and one second structure bone are evenly distributed in the form of triangle, and front ends of the three are commonly and tightly connected to one side of the fixing disk; the other side of the fixing disk is fixedly connected with the high definition camera, the lighting module of the high definition camera is located on an extension line of the second structural bone; the supporting component is a slender body structure, and the back end of the supporting component is connected with the three-degree-freedom driving unit; a channel for making cables of the first structure bone, the second structure bone and the high definition camera cross through are arranged on the supporting component; two first structure bones and the back end of the second structure bone are connected with the three-degree-freedom driving unit after crossing through the supporting component; the thin wall pipe is sleeved at the outer part of the supporting component.

Description

technical field [0001] The invention relates to a flexible manual cystoscope through the urethra, which belongs to the field of medical instruments. Background technique [0002] In the modern medical field, minimally invasive surgery has achieved success in reducing patients' postoperative pain and complications, shortening hospital stay, and improving postoperative scar conditions. In this field, the da Vinci porous laparoscopic surgical robot developed by Intuitive Surgical, which has been successfully commercialized, can meet the requirements of various minimally invasive surgeries. However, with the maturity of medical technology and the higher and higher requirements of patients, there has been naturalorifice trans-luminal endoscopic surgery (NOTES), which is characterized by the fact that no incision is required, and surgical instruments need to pass through a long and narrow cavity. The complex human cavity then arrives at the surgery department for operations such ...

AI Technical Summary

Problems solved by technology

At present, most of the existing surgical robots, including da Vinci, are difficult to meet the technical requirements of surgery through the natural orifice of the human body due to the limitations of rigid structure, appearance size, and degree of freedom configuration, especially for urinary tract surgery performed through the urethra.
