A surgical robot retractor

Abstract

The invention discloses a surgical robot retractor and belongs to the field of medical devices. The surgical robot retractor comprises a bottom plate (1), a rotating rod (2) and two hook portions (4), a vertical plate distributed perpendicularly to the bottom plate is arranged on one side of the bottom plate, the bottom plate comprises a motor bottom plate (101), a passage for the rotating rod to pass is arranged on the vertical plate, the rotating rod penetrates the passage to be fixed on the vertical plate, the tail end of the rotating rod is connected with a motor (6) which is controlled through a remote-end control device, the hook portions cooperate to open a surgical part and are connected with the rotating rod (2) through a transmission rod component (3), and a hook head (401) is arranged at the tail end of each hook portion; the transmission rod component (3) comprises a nut member (302) in threaded connection with the rotating rod, and opening and closing of the hook portions are controlled through movement of the nut member.

Description

technical field [0001] The invention relates to the field of surgical robot medical equipment. Background technique [0002] Retractors, also known as retractors, are used to retract tissue to expose the area to be operated for easy exploration and operation. They can be divided into two types: hand-held retractors and automatic retractors. There are various specifications of different shapes and sizes, and the appropriate retractor can be selected according to the operation needs. [0003] Retractors are usually used for incision fixation in surgical operations, such as neurosurgery, cardiothoracic surgery, urology, anorectal surgery, hepatobiliary surgery, plastic surgery, microsurgery, etc. The current retractor is usually controlled by a pair of hooks. Open and close to fix the incision, and the end is controlled remotely by structures such as scissor handles. [0004] Medical robots have been increasingly used in surgery. Medical robots usually include ordinary medica...

AI Technical Summary

Problems solved by technology

[0006] Existing retractors usually need to extend the hook into the wound first, and then open the wound, which will not take advantage of subsequent recovery, and the wound is relatively large;

[0007] Existing retractors usually have a scissor handle structure and some screw drive, but they need to be fixed by one person all the time. In the case of long operation time, the size of the wound will change. Usually in some dead angle positions, manual retraction is very difficult. Difficult to operate
