Integrated multi-degree-of-freedom unipolar electric hook

Abstract

The invention relates to the technical field of medical instruments, in particular to an integrated multi-degree-of-freedom unipolar electric hook. The integrated multi-degree-of-freedom unipolar electric hook comprises an instrument box, an instrument rod and an end effector, the end effector comprises a connecting base, a pitching ring, an electric hook support, an electric hook and a wire, and the connecting base comprises a connecting pipe and a connecting lug; the pitching ring comprises connecting rings and a connecting block, and the connecting block is hinged to the connecting lug corresponding to the connecting block in position; the electric hook support is of an inverted-U-shaped structure, the upper end of the electric hook support is connected with an electric hook, and the lower end of the electric hook support is inserted into inner cavities of the connecting rings at the two ends of the connecting block and hinged to the connecting rings; the upper end of the wire is connected with the electric hook, and the lower end of the wire penetrates through the electric hook support, the deflection pin shaft, the connecting base and the instrument rod and then is connected with parts in the instrument box; and the pitching ring is connected with the pitching steel wire assembly, and the electric hook support is connected with the deflection steel wire assembly. The integrated multi-degree-of-freedom unipolar electric hook is convenient to assemble, high in use safety and reliability and capable of flexibly rotating, pitching and deflecting.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an integrated multi-degree-of-freedom monopolar electric hook. Background technique [0002] In minimally invasive surgery, surgical robots put forward high requirements for the use of surgical instruments in contact with the human body. In minimally invasive surgery, monopolar electric hooks can significantly improve the efficiency of surgical operations and increase the safety of surgery, especially in the treatment Bleeding has a very high application value. Therefore, it is of great significance to provide a safe and efficient monopolar electric hook minimally invasive surgical instrument for performing operations such as cutting and stripping in robotic minimally invasive surgery. [0003] There are still many deficiencies in the manufacturing and clinical application of the existing unipolar electric hooks, for example: (1) the front end effector mostly uses surfac...

Problems solved by technology

[0003] There are still many deficiencies in the manufacturing and clinical application of the existing unipolar electric hooks, for example: (1) the front end effector mostly uses surface spraying or adds ceramic isolation devices to achieve leakage protection, and its processing and assembly processes are complicated; (2) The front end of the single-pole electric hook cannot have the functions of rotation, pitch and deflection, or the structure for realizing rotation, pitch and deflection is complex and inconvenient to operate; (3) The design of the internal wire routing is unreasonable
