AI Technical Summary

Technical Problem

When indwelling the traditional ureteral stent can easily cause symptoms such as bladder irritation, hematuria, low back pain, etc., and the removal process is complicated and requires special equipment and operating rooms to increase the pain and financial burden of the patient.

Method used

A ureteral stent tube and removal device including a stent tube, guidewire, push tube, catheter and grabber was designed. The stent tube was equipped with a tail wire and a suction cup. Through the cooperation of the guidewire and push tube, the kidney end of the stent tube forms a pig tail like a pig's tail, and the tail wire floats in the bladder and is captured through the suction cup, simplifying the extraction process.

Benefits of technology

The device makes the removal process of stent tubes easier, reducing the pain and financial burden on the patient, while reducing the need for use of special instruments and operating rooms.

Abstract

The utility model belongs to the technical field of medical instruments, in particular to a ureter stent tube and a pulling device, which comprises a stent tube, a guide wire, a pushing tube, a catheter and a catcher, a plurality of tail wires are arranged on the stent tube, a plurality of suckers are arranged on the tail wires at equal intervals, one end of the pushing tube wraps the tail wires and is sleeved at the outer end of the stent tube, and the other end of the pushing tube is sleeved at the outer end of the catheter. A first operation cavity, a second operation cavity, an air inflation cavity and a water injection cavity are formed in the catheter, the first operation cavity and the second operation cavity facilitate penetrating of the guide wire and the capturing device, the air inflation cavity facilitates air inflation into the air bag, the water injection cavity injects water into the bladder, a traction base, a mounting plate and a reset spring are arranged in the capturing device, and the traction base is connected with the mounting plate and a pull ring through a traction rope. By means of the device, a stent tube can be directly pulled out conveniently, pain and inconvenience caused by pulling out of special instruments such as a cystoscope and a ureteroscope can be avoided, and meanwhile the economic burden of a patient is reduced.
