Minimally invasive scalpel for urinary surgery and control method thereof

Abstract

The invention belongs to the technical field of medical instruments, and discloses a minimally invasive scalpel for urinary surgery and a control method thereof. A hollow supporting rod is welded to the right end of a telescopic handle, a supporting rod is welded to the right end of the hollow supporting rod, an oval stirring protruding point is fixed to the upper end of the supporting rod througha screw, a camera is embedded in the oval stirring protruding point, and the lower end of the supporting rod is connected to a cutting disc through a connecting rod; and the telescopic handle is provided with a telescopic outer cylinder, a telescopic inner rod is sleeved by the telescopic outer cylinder, a through hole is formed in the telescopic outer cylinder, a groove is formed in the telescopic inner rod, the bottom of the groove is connected to a clamping block through a spring, and the clamping block is clamped in the through hole. The scalpel is provided with the telescopic handle, sothat the length of the telescopic handle can be adjusted according to the size of the palm of a doctor, the handle is convenient to grasp, and the operation stability is improved; and the scalpel is provided with a current sensor, so that the current on electric wires is detected in the burning and cutting process of focus tissues, and reliable data reference is provided for burning and cutting the focus tissues.

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...
