A mechanical arm for urinary surgery operation

Abstract

The invention provides a mechanical arm for urinary surgery operation. The mechanical arm comprises a pedestal, a mechanical arm rotating mechanism, a rotating arm mechanism, a thick tube feeding mechanism, a thick tube rotating mechanism and a thin tube feeding mechanism. The mechanical arm rotating mechanism is fixed on the pedestal and is provided with a rotating boss; the rotating arm mechanism comprises a first rotating arm, a first motor, a second rotating arm and a second motor; the rear end of the first rotating arm is hinged to the rotating boss and a hinge joint shaft is fixedly connected with an output shaft of the first motor; the rear end of the second rotating arm is hinged to the front end of the first rotating arm, and a hinge joint shaft is fixedly connected with an output shaft of the second motor; the front end of the second rotating arm is in hinged joint with the thick tube feeding mechanism; the thick tube feeding mechanism is connected with the thick tube rotating mechanism; the thick tube rotating mechanism is connected with the thin tube feeding mechanism. The mechanical arm for urinary surgery operation has the advantages that the mechanisms can output specific movements to replace surgery tool operation of arms of surgery doctors, so that the labor intensity of doctors is reduced and accurate and standard surgery is achieved.

Description

technical field [0001] The invention relates to a surgical robot operating device, in particular to a mechanical arm for urological surgery. Background technique [0002] Urological diseases have become one of the most common diseases affecting human health in modern society. In the treatment of urological diseases, transurethral operations account for a large proportion, such as the treatment of benign prostatic hyperplasia (BPH), a common disease in men. BPH operation is one of the most common operations in urology. According to statistics, about 30-60% of the operations in urology in the country are benign prostatic hyperplasia operations. Prostate surgery is mainly minimally invasive, and transurethral resection of the prostate or laser vaporization is currently the most effective method for the treatment of BPH. At present, such operations mainly rely on doctors to perform operations manually. [0003] Since the surgical tool usually needs to achieve more than five d...

Problems solved by technology

In addition, due to the large amount of surgery, doctors are prone to fatigue after long-term surgery, which makes it difficult to guarantee the accuracy of surgery, and manual operation is not conducive to standardization of surgery and remote operation

On the other hand, although there are currently clinical surgical robots on the market, the existing surgical robots have comprehensive functions, complex structures, and high maintenance costs, resulting in high surgical costs and complicated operating procedures, requiring special training before they can be operated.

It can be seen that the existing surgical robots are not very pertinent to urological surgery. It is necessary to develop a robot mechanism specially used for urological surgery to imitate the doctor's arm to perform various actions required in the surgical process.
