Description

Disposable cystoscope tube-drawing foreign body forceps

Technical Field

The invention relates to the technical field of medical instruments, in particular to a pair of disposable cystoscope tube drawing foreign body forceps.

Background

The double J-tube is also called a pigtail catheter, is suitable for the upper urinary tract operation such as kidney stone, ureteral stone, hydronephrosis, kidney transplantation, benign tumor of kidney and ureter and the like, and the treatment process such as lithotripter lithotripsy, ureter stenosis expansion, vesicoureteral reimplantation and the like, is implanted into a patient body during the operation, is generally made of silicon rubber or polyurethane high polymer material which cannot be degraded and absorbed in the human body, when in the operation, elbows at two ends of the double J-tube are respectively placed in a renal pelvis and a urinary bladder of the human body, and the middle part of the double J-tube is placed in the ureter connecting the renal pelvis and the urinary bladder, so as to play important roles of draining urine, preventing ureter stenosis and adhesion blockage, and is generally taken out after being implanted into the human body for 1 month, at present, the taking out of the double J-tube needs invasive operation, for example, a cystoscope and a foreign body taking-out clamp are used for taking out the double J-tube through a urethra, but the using effect of the traditional instrument is poor, be the stereoplasm structure, the price is higher, and stretch into the urethra back simultaneously, and is bulky, and the cooperation operation is complicated, and the foreign matter is taken out pincers clamp and is got two J pipe difficulties, and partial patient needs to operate under the anesthesia, leads to this process to cause patient's very big misery, arouses patient's urethral tissue damage even, takes place to infect and hydroncus, for this reason, we propose disposable cystoscope extubation foreign matter pincers.

Disclosure of Invention

The invention aims to provide disposable cystoscope tube drawing foreign matter forceps which have the advantage of good use effect and solve the problems that the traditional instruments are poor in use effect, are of hard structures, are high in price, are large in size and complex in matching operation after extending into a urethra, are difficult to clamp double J tubes when the foreign matter is taken out of the forceps, and are partially needed to be anesthetized to operate, so that great pain is caused to a patient in the process, and even the urethral tissue of the patient is damaged, and infection and edema occur.
