Single-hole surgical device and medical equipment system

Abstract

The invention discloses a single-hole surgical device and a medical equipment system. The single-hole surgical device comprises a shell and at least one sheathing canal; the shell is tubular and comprises a horn mouth at the top and a shrink mouth at the bottom; one end of the sheathing canal extends into the shell and is communicated with the shrink mouth of the shell, and the other end of the sheathing canal extends out of the shell from the horn mouth; the sheathing canal comprises an inner sheathing canal section and an outer sheathing canal section; the inner sheathing canal section is located in the shell; the outer sheathing canal section is located outside the shell; and the outer sheathing canal section can deform; and deformation comprises deformation in the radial direction and / or the axial direction of the sheathing canal. The problem that the positioning precision of a moving arm is not enough due to machine control precision or other reasons is solved through partial structural improvement, higher permissibility is achieved for the position and angle of at least part of a medical tool entering a preset surgical site through the single-hole surgical device, and the production cost change is small.

Description

technical field [0001] The invention relates to a single-hole surgical device and a medical equipment system, belonging to the technical field of medical equipment. Background technique [0002] Single-port laparoscopic surgery is a form of surgery that has been gradually developed and widely used in recent years. It has the advantages of small wounds. In the past two years, a group of surgical robot products led by American Da Vinci Company have optimized the surgical form through computer remote control technology. , to achieve higher stability and precision surgical operations through the robotic arm. During the operation, the robotic arm is inserted into the human body by poking the card, and surgical operations on different parts are realized by controlling the joints of the surgical arm and surgical instruments. [0003] At present, the use of surgical robots to realize the surgical process mainly includes three processes: preoperative preparation, surgical operation,...

Problems solved by technology

[0003] At present, the use of surgical robots to realize the surgical process mainly includes three processes: preoperative preparation, surgical operation, and postoperative finishing. Among them, there will be a surgical assistant (usually an assistant doctor or nurse) before the operation. The mechanical arm is in a suitable position, fixedly connected with the mechanical arm and the poking card, and a medical tool with a surgical operation instrument at the end is set on the mechanical arm, so that the surgical operation instrument can enter the corresponding position in the human body through the poking card; however, due to Due to the limitation of the motion control accuracy of the robotic arm itself, when the user finally positions the robotic arm module so that the surgical instrument enters the human body through the poking card, it may not be able to achieve the relative and absolute position of the poking card design, resulting in the need for the user to readjust the mechanical arm. The angle of each degree of freedom of the arm so that the surgical instrument can enter the poking card smoothly
