Problems solved by technology

There are two types of ureteroscopes currently used: rigid ureteroscopes and flexible ureteroscopes. Rigid ureteroscopes have the advantages of good directionality and easy operation and insertion, but there are blind spots in vision and operation. Although soft ureteroscopes can eliminate vision and Operation blind zone, but the lens body is soft, poor controllability, difficult to operate, long learning curve, expensive, easy to damage

Embodiment Construction

[0013] When using the end-bendable ureteroscope of the present invention for diagnosis or treatment of upper urinary tract diseases, the insertion method is the same as that of a rigid ureteroscope, which needs to enter the bladder from the urethra, and can be directly inserted into the ureter without a ureteral expansion sheath, and reach the renal pelvis or calices. When inserted, the end of the flexible endoscope body is kept in line with the axis of the rigid endoscope body. When it is necessary to perform diagnosis and treatment operations, the direction of bending movement and Angle, eliminate observation and operation blind spots. Since most of the mirror body is a rigid structure, the loss of refraction and reflection during the transmission of the light source is reduced, so the vision under the mirror is also clearer.

[0014] The end-bendable ureteroscope is composed of a flexible endoscope body 2, a rigid laparoscopic lens body 1 and an operation key 3 on the rear...

Abstract

The invention discloses a mini-incision endoscope for diagnosis and treatment of upper urinary tract diseases, which is a novel ureter endoscope comprising an end flexible base 1, an operating grip 4, an operational key 3 for controlling the bending motion of the base end, since the main portion of the base of the end flexible ureter endoscope is of hard structure, whose end portion can be bent upwards or downwards by 180 degrees, the viewing field blind area and operation blind area of the hard ureter endoscope can be eliminated.

Description

technical field [0001] The invention belongs to the medical field and relates to a minimally invasive endoscope used for diagnosis and treatment of upper urinary tract diseases. Background technique [0002] Ureteroscopy is a kind of endoscope for diagnosis and treatment of diseases in the upper urinary tract of the urinary system with the help of special instruments. It does not need to make large incisions in the human body, significantly reducing damage to tissues, thereby speeding up the recovery of the body and shortening the course of treatment. Improving the curative effect is an important development of endoscopic technology. Its clinical application has changed the long-standing traditional concept that the ureter, renal pelvis and calyces are difficult to visually inspect and that upper urinary tract diseases must be treated with open surgery. There are two types of ureteroscopes currently used: rigid ureteroscopes and flexible ureteroscopes. Rigid ureteroscopes ha...
