Problems solved by technology

[0003] There are two types of ureteroscopes currently used: rigid ureteroscopes and flexible ureteroscopes. Rigid ureteroscopes have the advantages of good directionality, easy operation, and insertion, but rigid catheters cannot be bent, and there are blind spots in vision and operation.
Although the flexible ureteroscope can eliminate the visual field and operation blind area, the catheter is soft, poorly controllable, difficult to operate, expensive, and easily damaged

Embodiment

[0038] like figure 1 As shown, it is a flexible tapered endoscopic catheter with a braided wire structure disclosed in the present invention, which includes a tube body 1, and the end of the tube body 1 close to the operator is defined as the tube body proximal end 2, and the tube body 1 extends into One end inside the human body is defined as the distal end 8 of the tube body.

[0039] like figure 2 and 3 As shown, the tube body 1 is sequentially provided with a bottom tube 5 , a braided silk wrapping layer 3 and a sleeve 4 from inside to outside. The tube body 1 includes at least two segments with different hardness, each segment is made of the same flexible and deformable material, and the hardness of multiple segments decreases sequentially from the proximal end 2 of the tube body to the distal end 8 of the tube body. Small.

[0040] Wherein, the bottom pipe 5 is made of a flexible and deformable material. In this embodiment, the flexible and deformable material is po...

Abstract

The invention discloses a flexible tapered endoscope catheter with a braided wire structure and belongs to the field of medical apparatuses and instruments. The endoscope catheter includes a catheterbody, the end, close to an operator, of the catheter body is regarded as the proximal end, and the end, stretching into the human body, of the catheter body is regarded as the distal end; the catheterbody includes bottom tubes and braided silk wrapping layers fitting the outer sides of the bottom tubes and comprises at least two segments different in hardness, wherein the bottom tubes are integrally formed, and the bottom tube in each segment is made of a same flexible deformable material. The endoscope catheter can not only meet the hardness requirement but also have high flexibility, and therefore operation view dead zones are avoided; moreover, the endoscope catheter is also high in controllability and unlikely to be broken.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a flexible tapered endoscopic catheter with a braided wire structure. Background technique [0002] Ureteroscopy is a kind of endoscope that uses special instruments to diagnose and treat diseases in the upper urinary tract of the urinary system. It does not need to make large incisions in the human body, which significantly reduces 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 in 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. [0003] There are two types of ureteroscopes currently used: rigid ureteroscopes and flexible ureteroscopes. Rigid ureteroscopes ...
