Problems solved by technology

The existing ureteroscope cannot monitor the temperature in the ureter during the process of holmium laser lithotripsy, especially when crushing larger stones, the holmium laser works continuously for a long time, which may cause thermal damage to the ureter

Abstract

The invention provides an ureteroscope with a temperature sensor and belongs to the field of medical apparatuses and instruments. The ureteroscope comprises a mirror of a handheld portion and a mirrorbody connected to the mirror, wherein a temperature sensor probe is arranged at the front end of the mirror body and is connected with a wiring post on the mirror through a wire, and the wiring postis connected with a temperature sensor processing unit through a connecting wire. The temperature sensor processing unit is connected with a displayer capable of displaying temperature at the probe inreal time. The temperature sensor processing unit is also connected with a relay, and the relay is serially connected between a holmium laser mainframe and a pedal switch. When the local temperaturein the ureter exceeds a set value in the laser lithotripsy process, the relay is disconnected, even if an operator still treads the pedal switch at the moment, holmium laser also does not work, the relay is turned on when the local temperature in the ureter is reduced to a normal range, and holmium laser can continue to work by treading the pedal switch. Therefore, complications such as postoperative ureterostenosis caused by local thermal injuries of the ureter can be prevented in the laser lithotripsy process.

Description

technical field [0001] The invention relates to a medical device, in particular to a ureteroscope with a temperature sensor. Background technique [0002] A ureteroscope is an endoscope used for minimally invasive surgery in urology, comprising a mirror body provided with an eyepiece, a cold light source interface, a water inlet and outlet, and a slender mirror body. During the operation, the ureteroscope enters the ureter through the urethra, bladder, and ureteral orifice. With the help of the TV monitoring system, lesions in the ureter, such as stones and tumors, can be clearly observed. Ureteroscopy is widely used in urological surgery, including lithotripsy under ureteroscopy, among which holmium laser lithotripsy under ureteroscopy is the most widely used at present. During the operation, the holmium laser fiber is put into the ureter through the working channel of the ureteroscope, and the operator controls the holmium laser host to emit the holmium laser through the ...
