Abstract

The utility model discloses a prostate traction fixing catheter device, comprising a catheter [1], an urethral catheterization hole [2] in the front end of the catheter [1] and a gas bag [3], which is characterized in that: the catheter [1] is provided with an elastic ring[4] which can slide along the external wall of the catheter [1] and be in interference fit with external wall of the catheter [1]. The utility model has the advantage that the movement of the elastic ring can adjust the distance between the elastic ring and the gas bag [3] and thus can effectively drag a fixed gas bag which stresses bladder neck and prostate gland fossa in order to stop bleeding.

Description

A kind of prostate traction and fixation pipe guide

Technical field this utility model belongs to prostate traction and fixation pipe guide medical apparatus and instruments, especially for fixing and effective a kind of prostate traction and fixation of the hemostatic pipe guide of prostatectomy rear haulage.

Background technology is at present in urological operative treatment; run into the traction and fixation that the prostatic hyperplasia patient is carried out the prostatectomy postoperative through regular meeting and carry out the hemostatic problem; and this operation generally all is to adopt catheter as basic apparatus; then; fasten with gauze thereon, shift radix penis part onto with traction and fixation catheter air bag.Though this method is simple and convenient, in case gauze has been fastened, can cause that catheter is obstructed, can't drainage of urine or flushing, and the gauze pine no traction and fixation effect, and trouble is bothersome when removing gauze.For addressing this problem, technical solution of the present utility model has been proposed.Goal of the invention of the present utility model is in order to provide a kind of the patient to be carried out the neck of bladder traction, makes catheter unobstructed again simultaneously, carries out effective hemostatic device.A kind of prostate traction and fixation pipe guide promptly is provided.

Summary of the invention has proposed goal of the invention of the present utility model for solving the problem of above-mentioned existence.The technical solution of the present utility model purpose is in order to provide a kind of the patient to be carried out the neck of bladder traction, makes catheter unobstructed again simultaneously, carries out effective hemostatic device.Be that goal of the invention of the present utility model provides a kind of prostate traction and fixation pipe guide.

This kind prostate traction and fixation pipe guide, it has conduit [1], the urethral catheterization hole [2] of conduit [1] front end and air bag [3], it is characterized in that on conduit [1], having one can be that slide and the elastic ring [4] of outer wall interference fit conduit [1] along the outer wall of conduit [1].

The utility model has the advantages that by moving of elastic ring can adjust its with air bag [3] between distance, thereby can draw effectively and fixation balloon, stop blooding to oppress the prostate nest.The mechanism of action of the beneficial effects of the utility model is, because the cooperation between elastic ring and the catheter is an interference fit, have bigger interference fit power and frictional force between the two, these two power are enough to overcome the muscle resilience force at corrective surgery position, thereby can fix the position effectively.In addition, although be interference fit between elastic ring and the rubber urinary catheter, its interference restraining forces is that the circumferential catheter that therefore can not cause that is distributed on catheter produces tension or loose excessively phenomenon because of being fixed.

Appended drawings 1 is a topology view of the present utility model, and accompanying drawing 2 is the cutaway views at the elastic ring place of accompanying drawing 1, and the sequence number in the accompanying drawing is: 1, conduit, 2, catheterizing port, 3, air bag, 4, elastic ring.

The specific embodiment is with reference to accompanying drawing, prostate traction and fixation pipe guide of the present utility model, it has conduit [1], the urethral catheterization hole [2] of conduit [1] front end and air bag [3], it is characterized in that on conduit [1], having one can be that slide and the elastic ring [4] of outer wall interference fit conduit [1] along the outer wall of conduit [1].According to routine catheter is inserted into intravesical during use, injecting gas or liquid in air bag fill air bag, with urinary catheter in bladder and urethra.When needs draw the prostate nest, will move to air bag one end with the elastic ring of catheter interference fit, can carry out suitable traction compressing to the prostate nest really up to it and both can.Its mechanism of action is, because the cooperation between elastic ring and the catheter is an interference fit, has bigger interference fit power and frictional force between the two, and these two power are enough to overcome the muscle resilience force at corrective surgery position, thereby can fix the position effectively.In addition, although be interference fit between elastic ring and the rubber urinary catheter, its interference restraining forces is that the circumferential catheter that therefore can not cause that is distributed on catheter produces tension or loose excessively phenomenon because of being fixed.When removing traction, elastic ring moved in the opposite direction get final product, elastic ring can use and the catheter identical materials, perhaps the elastomeric material that hardness is higher or other elastomeric materials.

Claims

1, a kind of prostate traction and fixation pipe guide, it has conduit [1], the urethral catheterization hole [2] of conduit [1] front end and air bag [3], it is characterized in that on conduit [1], having one can be that slide and the elastic ring [4] of outer wall interference fit conduit [1] along the outer wall of conduit [1].
