Technical Field

The utility model relates to the field of medical equipment, in particular to ureteral stent remover.

Background

Urology often embeds ureteral stents in the ureter of a human body according to the needs of treatment, wherein the ureteral stents are also called double J tubes, DJ tubes or pigtail tubes. The ureteral stent needs to be pulled out of the human body through the urethra after being kept in place for a period of time. At present, the common practice in hospitals is to send a patient to an operating room, operate an endoscope by a doctor to insert from a urethra to a bladder, observe through an eyepiece and find a ureteral stent, then extend an operating forceps into a working channel of the endoscope, and then clamp the ureteral stent and pull out the ureteral stent to the outside of the body.

The traditional tube drawing method has the following problems: 1. the ureteral stent can be pulled out of a body by visual assistance of an endoscope, the structure is multiple, the operation is inconvenient, the operation environment is limited only in an operating room, the operating environment is limited, a patient who pulls out the ureteral stent usually needs to be queued for reservation because the operating room is nervous and a professional doctor is busy, and the cost for pulling out the ureter is high; 2. the endoscope is inserted from the urethra, and has a certain volume, so that the endoscope has a large influence on the urethra and is easy to injure the urethra, namely, the urethra is easy to be injured in the operation process, and a large psychological pressure or trauma is brought to a patient.

How to solve the above problems is a technical problem to be solved urgently.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple structure need not just can extract external ureteral stent remover with ureteral stent under the visual assistance of endoscope, does not receive the operating room to operate and it is less to the urethra influence when pulling out the operation when adopting this ureteral stent remover to pull out the operation.

In order to achieve the above object, the utility model provides a following technical scheme:

a ureteral stent remover comprises an elbow pipe and a removing structure which is used for being in plug-in fit with the elbow pipe; the utility model discloses a ureter bracket, including elbow pipe, pulling out structure, cover body, wherein, the elbow pipe front end of elbow pipe is the bending end, and, pull out the structure and include that the front end can pass the silk body of elbow pipe, install the cover body that is used for snatching ureter bracket at this silk body front end, install control handle at this silk body end.

Preferably, the cover is formed in a cover shape from at least two filaments.

Preferably, the front end of the filament body is a bendable end.

Preferably, the filament body is a metal wire with the length longer than that of the elbow pipe or a hard wire made of hard plastic.

Preferably, the elbow is a single-lumen tube, the elbow inlet is disposed at the elbow distal end of the elbow and the elbow outlet is disposed at the side or top of the elbow front end.

Preferably, the front end of the elbow pipe is provided with scales.

Preferably, the end of the elbow pipe is provided with a water injection joint for supplementing liquid to the bladder when urine is insufficient.

Due to the adoption of the structure, the utility model discloses the beneficial effect who has as follows:

the utility model discloses in, through the elbow pipe with pull out structure cooperation work, the elbow pipe inserts human bladder through the urethra, when the urine flows, inserts by the entry of elbow pipe and pulls out the structure and make the cover body stretch out the export of elbow pipe outside, the direction and the position of structure are pulled out in adjustment elbow pipe and through the control handle adjustment to make the cover body sheathe in ureteral stent and shift out the external ureteral stent that can realize pulling out ureteral stent together to the elbow pipe, pull out the structure and put in the area. Therefore, the utility model discloses it is external not need just to extract ureter support under the visual assistance of endoscope, can not need operate under the environment of operating room, at ward or nurse station, can pull out ureter support operation by the nurse, adopt promptly the utility model discloses do not be restricted to the operating room and operate when pulling out the operation. The utility model discloses thereby it is little to make the apparatus external diameter that gets into the urethra with the help of the endoscope not necessary, and is littleer to the urethra influence, can better protect the urethra, promptly the utility model discloses influence less to the urethra when pulling out the operation. Additionally, the utility model discloses simple structure, low in manufacturing cost, the utility model discloses reduced the cost of pulling out ureteral stent, alleviateed patient's economic burden, adopted the utility model discloses the operation of pulling out ureteral stent is equivalent to pulling out the catheter operation of inserting a small dimension, and the patient accepts relatively easily.

The invention will become more apparent from the following description when taken in conjunction with the accompanying drawings which illustrate embodiments of the invention.
