A kind of ureteral stent taking catheter

Abstract

The present invention relates to the technical field of medical devices, in particular to a catheter for taking a ureteral stent, including a catheter, an elbow part, an end part, a protective sealing plate, a perfusion channel, grasping forceps, a main pipe, a perfusion tube, an optical fiber access tube and a bladder Mirror, the right end of the catheter is fixedly connected to the left side of the elbow part, the right side of the elbow part is fixedly connected with the left side of the end part, and a working channel is opened in the middle of the lower part of the end part , a fiber channel is opened in the middle of the upper half of the end part. The present invention achieves the purpose of reusable use of the fiberscope in the postoperative shell, without any contact with human tissue without hindering the operation field of view generated by the optical fiber, so it can meet the requirement of one-time use, with low cost and price, no Pollution is generated, so after the operation, the fiberscope does not need to be sterilized and can be operated continuously.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a ureteral stent taking catheter. Background technique [0002] Clinically, after surgery for ureteral stenosis, blockage, and stones (including kidney stones, etc.), a ureteral stent will be placed. One end of the stent is placed in the bladder, passing through the ureter, and the other end is placed in the renal pelvis. It plays the role of expansion support and drainage after operation. However, the ureteral stent placed in the human body needs to be taken out after a certain period of time. The general time is about 1-3 weeks. The doctor will judge and decide the time to take it out according to the specific situation. A minor operation, under the action of a cystoscope, the ureteral stent is captured by grasping forceps. [0003] The working channel of the grasping forceps is on the cystoscope (integrated with the cystoscope), and the grasping forceps enter the bla...

AI Technical Summary

Problems solved by technology

[0003] The working channel of the grasping forceps is on the cystoscope (integrated with the cystoscope), and the grasping forceps enter the bladder through this working channel to grasp and remove the ureteral stent, and this instrument (cystoscope and grasping forceps) is repetitive The instruments used need to be completely and effectively sterilized and aseptically packaged after each use, and the operation can only be performed in the operating room, which is expensive. In addition, there are requirements for disinfection and sterilization after each use , so the operation schedule cannot be carried out continuously, that is, a cystoscope can only perform one operation in a short period of time, and there is also a one-time flexible cystoscope, but the cost is very expensive
