Description

Stay wire device convenient for taking out double J-tubes

Technical Field

The utility model relates to the technical field of urology surgical tools, in particular to a stay wire device convenient for taking out double J tubes.

Background

The double J-tube is a ureteral stent tube, is a medical instrument, and is an elongated hose in appearance. One end of the double J tube is connected with the bladder, and the other end is connected with the kidney. When the ureter is obstructed by stones, scar stenosis, tumors, etc., the ureter can be supported by implanting double J-tubes into the patient, thereby allowing urine to drain from the kidneys to the bladder. Meanwhile, ureteral procedures (including ureteroscopy, lithotripsy, and ureteral patency) and renal pelvis procedures (e.g., a pyelotomy, a lithotripsy, a nephroplasty, etc.) routinely require placement of double J-tubes. There is no dual J-tube that can be permanently left in the body, and after a period of use, it is necessary to remove the dual J-tube by invasive procedures, typically cystoscopic procedures. Clinically, a mode of reserving a thread end on the urethral head and then pulling out the double J-tube by utilizing the thread end is also adopted. However, the thread ends are required to be kept outside the body, so that the problems of easy infection and discomfort of the urinary tract are caused, and the use feeling of patients is poor.

Chinese patent document CN 102580224A describes a catheter and a ureteral stent device comprising the same, but the device still has the problem of inaccurate locking due to limited force when the pull wire is taken out; chinese patent document CN 102579171A describes a ureteral stent device, which has the problem that the fixation of the iron ring is unstable, and the contact part may be scratched. Chinese patent CN 201210055494.4 describes a design of wrapping a pull wire with a degradable coating. In the actual operation process, since the traction wire is discharged out of the body along with urine after the degradable coating is decomposed, however, if the condition of taking out the ureteral stent tube is not achieved, the ureteral stent tube is not suitable to be implanted into the patient again from the aspects of bringing new pain to the patient and economic cost. The free end of the traction wire which is discharged out of the patient is suspended at the urethral orifice, firstly, the exposed wire head is easy to be stained with dirt from the perspective of sanitation, and the dirt is easy to cause infection if entering the patient through the traction wire; secondly, the exposed thread ends of the traction thread are liable to cause discomfort to the person. Chinese patent document CN 212308143U describes a memory metal controlled self-draining ureteral stent, which is controlled by external heating to release a pull wire in order to pull the ureteral stent out of the body. However, none of these methods is simple and easy to implement.
