Portable device for removing ureteral stent through urethra

Abstract

Disclosed is a portable device for removing a ureteral stent through urethra. The portable device comprises a visible fiber optic endoscope sleeve and a visible fiber optic endoscope sleeved with thevisible fiber optic endoscope sleeve, wherein the fiber optic endoscope sleeve is provided with two independent channels including a fiber optic endoscope channel and a working channel; the visible fiber optic endoscope is arranged in the fiber optic endoscope channel; the front end of the optical fiber endoscope channel is a blind end and is transparent, sealed and capable of guiding light; the front end of the working channel and the front end of a ureteroscope are of the same structure; and a spring clamp is further arranged in the working channel, and the spring clamp can enter the bladderof a human body through the working channel. By means of the portable device, the visible optical fiber endoscope can be repeatedly used after an operation without sterilization treatment, on the premise that the optical fiber does not hinder the operation view field, the visible optical fiber endoscope does not make contact with human tissue at all, and therefore the portable device can meet thedisposable use requirement, is low in cost and price, does not generate pollution and facilitates continuous operation.

Description

technical field [0001] The invention relates to a medical instrument device, in particular to a portable device for pulling out a ureteral stent through the urethra. Background technique [0002] Clinically, after surgery for ureteral stricture and upper urinary tract stones, ureteral stents are routinely indwelled to play the role of expansion, support and drainage after surgery. Usually about 1-3 months, the foreign body forceps are pulled out under the cystoscope. The working channel of the foreign body forceps is on the cystoscope (integrated with the cystoscope). The foreign body forceps enters the bladder through this working channel to grab the ureteral stent tube. This instrument (cystoscope and foreign body forceps) is repetitive The instruments used need to be completely and effectively sterilized and aseptically packaged after each use, and this operation needs to be completed in the operating room or cystoscopy room, which is costly and has the possibility of cr...

Problems solved by technology

The working channel of the foreign body forceps is on the cystoscope (integrated with the cystoscope). The foreign body forceps enters the bladder through this working channel to grab the ureteral stent tube. This instrument (cystoscope and foreign body forceps) is repetitive The instruments used need to be completely and effectively sterilized and aseptically packaged after each use, and this operation needs to be completed in the operating room or cystoscopy room, which is costly and has the possibility of cross-infection. In addition, because After each use, there is a requirement for disinfection and sterilization, so surgery scheduling cannot be performed continuously, that is, a cystoscope can only be used once in a short period of time, especially in overcrowded large hospitals, patients may have to wait for the next day before removing the cystoscope, increasing the Patient's Financial Burden
