Surgery operating arm and surgery robot

Abstract

The invention discloses a surgery operating arm. The surgery operating arm comprises a bracket assembly, at least one movement assembly, a bending drive assembly and an endoscope. The bracket assemblycomprises a front supporting seat, a rear supporting seat and a bending assembly connected to the front supporting seat through a supporting rod, wherein the bending assembly comprises a rear end member, an intermediate member and a front end member, the rear end member is connected to the supporting rod, and the intermediate member and the front end member are pivotally connected to the rear endmember in sequence; each movement assembly comprises a plurality of transmission assemblies arranged in parallel; elastic lead screws of the transmission assemblies can slidably run through first through holes form in the front end member, the intermediate member and the rear end member respectively; a drive rope of the bending drive assembly can slidably run through second through holes formed in the front end member and the intermediate member respectively and is fixedly connected to the rear end member; the drive rope is suitable for the relative rotation of the front end member, intermediate member and rear end member, thereby promoting the elastic lead screws to perform elastic deformation. The surgery operation arm has the advantages of being convenient to operate and high in precision.

Description

technical field [0001] The invention relates to the field of surgical medical instruments, in particular to a surgical operation arm and a surgical robot used in minimally invasive surgery of the larynx. Background technique [0002] Laryngeal diseases are common and frequently-occurring diseases that often require surgical treatment. The common treatment method is endoscopy with surgical instruments. Since the larynx is one of the most complicated areas in the human body structure, it has the characteristics of small cavity, deep position, dense nerve and blood vessels, etc., so it puts forward higher requirements for surgical operators. In addition to overcoming the problems of lack of depth sense in endoscopic two-dimensional images and insufficient flexibility of instruments, the throat surgery robot can also effectively reduce surgical trauma and bleeding, shorten operation time, and enable patients to recover faster after surgery. Wide application prospects. [0003]...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to provide a surgical operation arm based on transmission parts driven by multiple parallel elastic screw rods, aiming at the disadvantages of inconvenient operation and low precision of existing surgical robots, especially throat surgical robots, and a surgical robot employing the surgical manipulator, which is particularly suitable for assisting surgeons in laryngeal surgery
