Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a uretero-nephroscope.
In order to solve the technical problems, the technical scheme provided by the invention is that the uretero-nephroscope comprises the following components: the device comprises a lens tube, optical fiber channels symmetrically arranged at two sides below the lens tube, an operation channel arranged below the lens tube, a target tube sleeved outside the lens tube, the optical fiber channels and the operation channel, and a target body arranged at one end of the target tube; a water inlet channel is arranged among the target tube, the lens tube, the optical fiber channel and the operation channel, a handle is arranged at the opposite outer end of the target body, a water inlet interface communicated with the water inlet channel is arranged at the upper part of the handle, a water outlet interface communicated with the operation channel is arranged at the bottom of the target body, a pressing adjusting button is arranged at the forefinger holding part of the handle, a rotating adjusting button is arranged on the side surface of the handle, and the pressing adjusting button and the rotating adjusting button control the water pressure; the opening of the target tube far away from the handle end is an oblique opening, and the operation channel and the optical fiber channel are arranged in a triangular shape.
As an improvement, the lens tube comprises an optical fiber channel arranged on the outer side, a light source interface communicated with the optical fiber channel is arranged on the target body, and an eyepiece sleeve communicated with the lens tube is arranged on the target body.
As an improvement, the tail end of the operation channel is provided with a rubber plug.
Compared with the prior art, the invention has the advantages that: the insertion end of the invention is an oblique port, which is convenient for the target tube to be inserted into the urinary tract and to smoothly advance in the urinary tract, thereby avoiding the pain and injury of the patient caused by the insertion process, the water inlet and outlet can keep constant pressure in a closed space, the triangular design can ensure that the objects entering the water outlet channel can smoothly pass through the operation channel, the invention is provided with a handle and an adjusting device which are convenient for holding and adjusting the water pressure, the adjusting button is rotated to enable the water inlet and the water outlet to be equivalent and synchronously relieve the fatigue of the operator, the instant negative pressure suction and removal of foreign matters such as blood clots near the visual field can be realized by pressing the adjusting button, and the broken stone discharging efficiency of the broken stones.
