Ultrasonic percutaneous nephroscope integrated lithotripsy device and application thereof

Abstract

The invention provides an ultrasonic percutaneous nephroscope integrated lithotripsy device. The device comprises an operation tube and a control mechanism, wherein the operation tube is provided with an endoscope channel and an operation channel, a plurality of connectors are arranged on the control mechanism, a handle, a pull ring and a pull ring protection ring are arranged below the control mechanism, an arc groove, a clamping handle and a water outlet connector are arranged on the surface of the front end of the control mechanism, a chute block in an operation chamber of the control mechanism is in sliding connection with a rack, the rack is in meshed connection with a gear, a ratchet wheel is arranged on one side of the surface of the front end of the gear, a pawl is arranged on a shifting rod, a first connecting rod at the rear end of the gear is in shaft connection with a second connecting rod, and the second connecting rod is movably connected with a fixing sleeve. The handle can be held by a single hand to fix the insertion position and angle, meanwhile, the pull ring is matched with the position of the clamping handle, the extension length of a lithotripsy rod is adjusted, and the percutaneous nephroscope is connected with an ultrasonic lithotripsy device, so that the device can be operated by a single hand during an operation, other operations can be performed by the other hand, meanwhile, the device is detached at any time according to intraoperative operation, and therefore, the device has wide popularization and application values in the field of urinary calculus treatment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an ultrasonic percutaneous nephroscope integrated lithotripsy device and its application. Background technique [0002] The total incidence of urinary calculi in my country is 1%-5%. Urinary tract stones are more common in middle-aged men, with a male-to-female ratio of about (2-3):1. The high-incidence age for men is 30-50 years old, and there are two peaks for women, 35 and 55 years old. In recent years, the incidence of urinary calculi in women has a tendency to increase. Ultrasonic lithotripsy is mostly used at present. Ultrasonic lithotripsy has little damage to the kidney cortex. Ultrasonic lithotripsy does not require surgery. Usually, it is aimed at the position of the stone under the positioning of the X-ray machine and sent ultrasonic waves. Play the effect of shock wave gravel. [0003] The minimally invasive percutaneous nephrolithotomy is commonly known as...

Problems solved by technology

[0005] In view of the inconvenient operation when using ultrasonic percutaneous nephroscope or ureteroscope for lithotripsy in the prior art, it is impossible to control the extension length of the ultrasonic probe or the pneumatic ballistic lithotripsy rod, resulting in accidental injury to the surrounding soft tissues, poor lithotripsy effect and affecting the treatment effect To solve the problem, the present invention provides a lithotripsy device integrated with an ultrasonic percutaneous nephroscope, which can hold the handle with one hand to fix the insertion position and angle. The percutaneous nephroscope is connected to the lithotripsy rod of the ultrasonic lithotripsy device, which is convenient for operation with one hand, and other operations can be performed with the other hand. At the same time, it can be disassembled at any time according to the intraoperative operation. It has a wide range of popularization and application value in the treatment of urinary system stones
