Nephroscope capable of being operated by one hand

Abstract

The invention provides a nephroscope capable of being operated by one hand, and belongs to the field of medical instruments. The nephroscope comprises a nephroscope body, and the nephroscope body is provided with a handheld part; the handheld part is provided with a control groove used for controlling advancing and retreating of a laser optical fiber, the handheld part is further obliquely provided with an eyepiece, and the eyepiece inclines towards the direction of the control groove so as to achieve one-hand operation; a water stop cap used for preventing water leakage is detachably arranged on the tail portion of the handheld portion, and the control groove is formed in the water stop cap. The nephroscope can realize the simultaneous control of advancing and retreating of the laser lithotripsy optical fiber and the lens body by a single hand, and the other hand can regulate and control the operation sheath at any time to achieve the effect of continuous stone chasing and hitting, so that the lithotripsy efficiency is remarkably improved, the learning curve is shortened, and the mistaken hitting of the laser optical fiber on kidney mucosa is reduced.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a nephroscope which can be operated with one hand. Background technique [0002] Percutaneous nephrolithotomy (PCNL) is the first choice for clinical treatment of renal calculi and upper ureteral calculi. Rigid percutaneous nephroscope is a medical device used in percutaneous nephroscopic surgery. Rigid percutaneous nephroscope passes through the waist The back skin is punctured to reach the renal calyx and renal pelvis, and a channel from the skin to the kidney is established at the waist through puncture expansion, and an operating sheath is placed. The rigid percutaneous nephroscope reaches the target renal pelvis or renal calyx through the operating sheath; it is inserted from the operating channel of the nephroscope Lithotripsy tools such as laser fiber optics or ultrasonic probes crush and remove the stones. Percutaneous nephroscopic surgery is widely used beca...

AI Technical Summary

Problems solved by technology

[0005] Currently, when performing percutaneous nephrolithotomy, doctors operate with both hands, that is, one hand holds a nephroscope, and the other hand holds a laser optical fiber and other lithotripsy tools. Since the left and right hands are controlled by the right and left hemispheres of the brain, respectively; Among them, the two-handed operation, especially the fine lithotripsy in the kidney, has problems of running-in and co...
