Ureteroscope

Abstract

The invention discloses a ureteroscope, comprising at least two parts of lenses and a lens body, wherein each part of the lenses are connected in sequence; the tail end of the rear part lens is connected with the lens body; communicated tube cavities are arranged in each part of the lenses and the lens body; the external wall of the front part lens is provided with a groove; a tube wall of the rear part lens is provided with a drainage channel; and the groove and the drainage channel are communicated with each other. By additionally arranged a water drainage channel, the invention can accelerate the water drainage speed during an operation, forms continuous water cycle, increases the water drainage amount during the operation on the premise of not influencing the execution in the operation, thus not only can keeping clear view during the operation process and improving operation efficiency, but also reducing water pressure in a kidney and an ureter, preventing occurrence of hyperpyrexia bacteremia after the operation and avoiding rise of the water pressure in a bladder.

Description

Technical field [0001] The invention relates to a medical device, in particular to a ureteroscope. Background technique [0002] A ureteroscope is an endoscope used for minimally invasive surgery in urology. During the operation, the ureteroscope is inserted into the bladder through the urethra, and then into the ureter from the opening of the ureter. The ureter is explored through the ureteroscope, and the stones in the ureter are broken by lithotripsy equipment. [0003] The ureteroscope includes a first mirror body, a second mirror body, a third mirror body, and a mirror body. The three mirror bodies are connected in sequence, and the tail end of the third mirror body is connected to the mirror body; the three mirror bodies are connected to the mirror body. The lumen; the mirror body is provided with a light source entrance and an observation port, and the light source entrance and the observation port are respectively communicated with the lumen. When in use, the first and se...

AI Technical Summary

Problems solved by technology

[0006] 1. Since the water injection and drainage can only be operated separately, the water cycle cannot be formed, so the vision is often unclear during the operation;

[0007] 2. Continuous water injection will make the water pressure in the tip of the mirror and the kidney too high. If the operation time is long, it may even cause the water pressure in the bladder to be too high. At this time, the ureteroscope must be pulled out to drain the water in the bladder, and then inserted into the ureteroscope Re-operate;

[0008] 3. Water injection and drainage are operated separately, which will also affect the efficiency of the operation and prolong the operation time
