Operation auxiliary device for hepatobiliary surgery

Abstract

The invention discloses an operation auxiliary device for hepatobiliary surgery, belonging to the field of medical equipment. The operation auxiliary device comprise a device body, wherein a driving bin is arranged in the device body; an opening is formed in one side wall, corresponding to the driving bin, of the device body; a driving mechanism is arranged in the driving bin; two expanding and supporting assemblies are arranged on one side of the driving mechanism; one ends of the two expanding and supporting assemblies are driven by the driving mechanism; and the other ends of the two expanding and supporting assemblies penetrate through the opening, extend out of the device body and act on a sternum incision. According to the invention, a pull rod drives a rack to move forwards; at themoment, the rack is meshed with a first bevel gear when moving; the first bevel gear rotates to drive a second bevel gear to rotate; the second bevel gear drives a lead screw to rotate; two opposite external threads on the outer wall of the lead screw drive two sliding blocks to move towards two sides at the same time; so sternum expansion is achieved. The pull rod is adopted for driving the wholedevice to conduct expansion work; and compared with the conventional mode of expansion adjustment, expansion operation and expansion simulation in a rotating manner, the device of the invention is more convenient and smoother to use.

Description

technical field [0001] The embodiment of the present invention relates to the field of medical equipment, in particular to a surgical assisting device for hepatobiliary surgery. Background technique [0002] Hepatobiliary Surgery mainly studies hepatocellular carcinoma, hepatolithiasis, post-hepatitic cirrhosis and acute liver failure caused by severe hepatitis, which are major diseases that seriously threaten the health of Chinese people. Usually clinically, when performing hepatobiliary surgery on a patient, an open cavity operation is generally used. After the cavity is opened, the epidermal tissue or other tissues of the cavity need to be pulled apart to open the chest cavity of the human body to facilitate the operation. [0003] At present, it is generally assisted by several medical assistants to open the human body's chest cavity to facilitate the operation. Not only is the operation time-consuming and laborious, but the patient's pressure is increased. People add t...

Problems solved by technology

[0003] At present, it is generally assisted by several medical assistants to open the human body's chest cavity to facilitate the operation. Not only is the operation time-consuming and laborious, but the patient's pressure is increased. People add to the difficulty of the job

[0004] Therefore, surgical retractors have been used to assist surgery. When using surgical retractors for support and fixation, the adjustment is not only inconvenient, the operation is not smooth, and the adjustment accuracy is not high. Doctors need to operate according to the patient's condition.
