Embodiment Construction

[0033] Such as Figure 1-4 As shown, an electronic flexible ureteroscope includes a hose-shaped flexible scope body 1 and a lens holder 2 arranged at the front end of the flexible scope body 1. The lens holder 2 can be a bracket with a cylindrical structure. In addition, the entire flexible scope body 1 It is a medical hose structure, and the end of the hose structure can be made into a straight tube or a curved shape. The lens holder 2 is located at the front end of the soft mirror body 1. The lens holder 2 is provided with a lens installation channel 10, and the lens installation channel 10 A lens 3 is arranged inside, and the lens 3 is connected with the electronic endoscope image processor 7 outside the soft mirror body 1 through a transmission line arranged in the soft mirror body 1. The lens holder 2 is provided with a lens mounting hole inside, and the lens can be Fix the inside of the lens holder 2 by adhesives such as glue, and the end face of the lens can be flush wi...

Abstract

The invention relates to the technical field of medical apparatus and instruments, and particularly discloses an electronic flexible ureteroscope, a system and a using method. The electronic flexibleureteroscope comprises a flexible ureteroscope body in a hose shape and a lens bracket arranged at the front end of the flexible ureteroscope body, wherein a lens is arranged in the lens bracket, an energy output channel is formed in the flexible ureteroscope body, an energy output part can be arranged in the energy output channel, a hydraulic pressure detection channel is arranged in the flexibleureteroscope body, the front end of the hydraulic pressure detection channel extends to the front end surface of the lens bracket, and a hydraulic pressure sensor is fixed in the hydraulic pressure detection channel. The system comprises a handle, an electronic endoscopy image processor, an energy instrument, a temperature measuring instrument, a pressure measuring instrument and an endoscope irrigation system. According to the using method, when pressure intensity, detected by the hydraulic pressure sensor, in a cavity is larger than a limiting value, alarm can be sent out, a user is reminded to change energy output of the energy instrument, and the conditions that urosepsis is caused and even the patient's life is endangered due to the fact that fluid flows reversely and substances containing bacteria, toxins and pyrogen are brought into blood under too high hydraulic pressure are avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an electronic flexible ureteroscope, a system and a use method. Background technique [0002] Laser surgery system or ultrasonic surgery system is a relatively common interventional medical urinary lithotripsy equipment. Interventional laser lithotripsy or ultrasonic lithotripsy can save patients the pain of surgery. [0003] High temperatures are a major factor in the risk of all thermal lasers. Thermal causative laser, the principle of lithotripsy is to transform the laser energy into high temperature to achieve the purpose of melting stones. Thermal causative lasers generate high temperatures. The wavelength of the thermal laser is within the optimum absorption range of water, and the energy is easily absorbed by the liquid in the official cavity. The liquid close to the boiling point can cause continuous damage to the lumen, causing serious complications such as ed...
