Transurethral bendable surgical tool

Abstract

The invention relates to a transurethral bendable surgical tool. The transurethral bendable surgical tool includes a flexible continuum mechanical arm and a driving unit; the flexible continuum mechanical arm includes a first-section continuum and a second-section continuum. The first-section continuum includes four first structural bones, a plurality of first spaced disks and a first fixing plate, wherein the four first structural bones are arranged in parallel at equal intervals, the first spaced disks are arranged at equal intervals, the rear ends of the first structural bones are connected with the driving unit, and the front ends of the first structural bones pass through each first spaced disk in sequence and then are fixedly connected with the first fixing plate; the second-section continuum includes four second structural bones, a plurality of second spaced disks and a second fixing plate, wherein the four second structural bones are arranged in parallel at equal intervals, the second spaced disks are arranged at equal intervals, the rear ends of the second structural bones are connected with the driving unit, and the front ends of the second structural bones pass through each first spaced disk, the first fixing plate and each second spaced disk and then are fixedly connected with the second fixing plate.

Description

technical field [0001] The invention relates to a flexible transurethral surgical tool, 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 as clampin...

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.
