Urethral tractor

Abstract

The invention provides a urethral tractor which is used for being connected with the tail end of a balloon urethral catheter. The tractor comprises a casing, at least one coil pay-off and take-up mechanism arranged inside the casing, and a connecting part used for being connected with the tail end of the balloon urethral catheter, wherein the coil pay-off and take-up mechanism comprises a reel rotationally arranged on the casing, a pulling rope wound on the reel, and a volute spiral spring; the pulling rope is made of non-expansion material; a limiting chamber is formed on the reel; the volute spiral spring is limited in the limiting chamber; the volute spiral spring is provided with an inner end part and an outer end part; the inner end part of the volute spiral spring is fixed on the casing; the outer end part of the volute spiral spring is bent and is fixed on the reel; the pulling rope is provided with a fixed end fixed on the reel and a free end; the connecting part is fixed to the free end of the pulling rope. The urethral tractor is constant in pull force after operation and good in hemostatic effect, and ensures that lower limbs can freely move, so as to be possible for preventing complications, such as thrombus of lower extremity veins of patients and the like, after operation.

Description

technical field [0001] The invention relates to a urethral retractor, in particular to a urethral retractor used for urological related operations such as posterior urethral rupture, urethral reunion, open operation for benign prostatic hyperplasia, or transurethral resection of the prostate. Background technique [0002] At present, after urological surgical operations such as prostate resection, open prostatectomy, and urethral reunion, it is generally necessary to use a balloon catheter to pull and compress the hemostasis or to pull the catheter to facilitate the closure of the broken ends. The time usually lasts 12-24 hours after surgery, even several days. In the traditional technology, in order to complete the traction effect, it is necessary to paste the end of the balloon catheter on the inner side of one thigh or fix the balloon catheter with a bedside traction device (ie, the bedside traction method).

Problems solved by technology

In the traditional technology, in order to complete the traction effect, it is necessary to paste the end of the balloon catheter on the inner side of one thigh or fix the balloon catheter with a bedside traction device (ie, the bedside traction method). There are the following deficiencies in the rehabilitation of patients after resection of the prostate: 1. The urethra is pulled parallel to the coronal plane of the body for a long time, and urethral stricture is prone to occur in the long term; 2. The traction force cannot be quantified, and the traction force is too small to ensure the hemostatic effect ; If the traction force is too large, bladder neck contracture is likely to occur in the long term; 3. Some patients are prone to loosening when pasted on the inner thigh with adhesive tape, which cannot meet the effect of continuous traction; 4. Paste the catheter on one side of the thigh to restrict the patient's activities , prone to deep vein thrombosis, etc., and cause obvious discomfort to patients, and even cause pressure sores
