A minimally invasive scalpel for urology and its control method

Abstract

The invention belongs to the technical field of medical devices, and discloses a minimally invasive scalpel for urology and a control method thereof. The right end of the telescopic handle is welded with a hollow strut, the right end of the hollow strut is welded with a support rod, and the upper end of the support rod is fixed with an ellipse Toggle bumps, ellipse toggle bumps are embedded with a camera, the lower end of the support rod is connected to the disc knife through a connecting rod; the telescopic handle is provided with a telescopic outer cylinder, and the telescopic outer cylinder is sleeved with a telescopic inner rod, and the telescopic outer cylinder A through hole is opened on the top, a groove is arranged on the telescopic inner rod, the bottom of the groove is connected with the clamping block through a spring, and the clamping block is clamped in the through hole. The present invention is equipped with a telescopic handle, which can adjust the length of the telescopic handle according to the size of the doctor's palm, which is convenient for grasping the handle and improves the stability of operation; , to detect the magnitude of the current on the wire, and provide reliable data reference for burning and cutting lesion tissue.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a minimally invasive scalpel for urology and a control method thereof. Background technique [0002] Currently, the closest prior art: [0003] In clinical urological surgery, minimally invasive surgery is often performed, and advanced resectoscope minimally invasive scalpels are generally used to remove tumors. However, the length of the existing minimally invasive scalpel for urology is fixed and cannot be adjusted according to the size of the doctor's palm, which reduces the stability of the minimally invasive scalpel. At the same time, the existing minimally invasive scalpel for urology cannot obtain the position of the scalpel for detection during the operation, which reduces the accuracy of lesion tissue excision, and it is easy to excise the tissue around the lesion. [0004] In summary, the problems in the prior art are: [0005] (1) The length of t...
