Abstract
The application relates to the technical field of medical equipment, especially, relate to a resistance to compression ureteral stent, including the pipe, be equipped with the plastics elastic support body that is used for supporting the pipe that wears to locate in the pipe. The utility model provides a resistance to compression ureteral stent is equipped with plastics elasticity supporter in the pipe for the pliability of pipe is better, still can keep switching on the form under the circumstances of extrusion or discount, simultaneously because the supporting spring in the ureteral stent is made by plastics, the whole weight of ureteral stent is light on the throne, makes difficult the droing when arranging in between kidney and the bladder, prevents the emergence of medical malpractice.
Description
[ technical field ] A method for producing a semiconductor device
The application relates to the technical field of medical equipment, especially, relate to a resistance to compression ureteral stent.
[ background of the invention ]
The ureteral stent is widely applied to various operations of the urinary system at present due to the internal supporting and internal drainage functions. The ureter bracket can effectively relieve temporary upper urinary tract obstruction caused by upper urinary tract calculus and ureter edema, prevent postoperative ureter stenosis and urine leakage, and is beneficial to the recovery of the function of the affected side kidney. In the minimally invasive operation of urinary calculus, calculus is broken by means of laser and other calculus breaking tools, large calculus fragments can be flushed out through water flow and taken out through a calculus covering basket, powdered calculus (less than 2mm) is always discharged out automatically after operation, calculus powder can be discharged out orderly along the wall of a support through the placement of a ureteral support, and the internal drainage function of the ureteral support keeps the urinary tract unobstructed.
However, in the actual use process, the patient can laterally press the catheter due to sitting down, lying down and other actions, so that the catheter is pressed to be narrowed or blocked, and in some types of ureteral stents, in order to solve the problem, a steel wire spring is used for supporting the inner wall of the stent, and because the supporting spring in the ureteral stent is made of steel wires, the whole weight of the ureteral stent is heavier, so that the ureteral stent arranged between the kidney and the bladder is easy to fall off, the risk is high, and medical accidents are easy to cause.
[ summary of the invention ]
To the not enough of prior art, this application provides a resistance to compression ureteral stent.
The technical scheme adopted for solving the technical problem is as follows:
the pressure-resistant ureteral stent comprises a catheter, wherein a plastic elastic support body which is arranged in the catheter in a penetrating manner and used for supporting the catheter is arranged in the catheter.
The pressure-resistant ureteral stent has a spiral structure.
The pressure-resistant ureteral stent is characterized in that the plastic elastic support body is formed by arranging a plurality of plastic wires in an overlapping mode.
The pressure-resistant ureteral stent is characterized in that the catheter is made of medical silica gel materials.
Compared with the prior art, the ureteral stent has the beneficial effects that the plastic elastic support body is arranged in the catheter, so that the flexibility of the catheter is better, the catheter can still keep a conduction state under the condition of extrusion or folding, and meanwhile, because the support spring in the ureteral stent is made of plastic, the whole weight of the ureteral stent is light, so that the ureteral stent is not easy to fall off when being placed between the kidney and the bladder, and medical accidents are prevented.
[ description of the drawings ]
Fig. 1 is a schematic structural view of a ureteral stent of the present application;
fig. 2 is a schematic cross-sectional view of a ureteral stent of the present application.
[ detailed description ] embodiments
The present application will be further described with reference to the following drawings and specific embodiments.
Referring to fig. 1 and 2, a pressure-resistant ureteral stent comprises a catheter 1, wherein a plastic elastic support body 2 for supporting the catheter is arranged in the catheter 1, and penetrates through the catheter, and the catheter 1 is made of a plastic material with shape memory, such as a medical silica gel material, so that the catheter can still keep a better original state after being bent for multiple times. Specifically, the plastic elastic support body 2 adopts a spiral structure, such as a structure formed by overlapping and arranging a plurality of plastic winding wires, can provide a certain supporting force for the wall of the catheter, can still keep the catheter in a conducting state under lateral pressure, can effectively prevent the catheter from being extruded and narrowed to block the catheter, and improves the safety of the catheter.
The utility model provides a resistance to compression ureteral stent is equipped with plastics elasticity supporter in the pipe for the pliability of pipe is better, still can keep switching on the form under the circumstances of extrusion or discount, simultaneously because the supporting spring in the ureteral stent is made by plastics, the whole weight of ureteral stent is light on the throne, makes difficult the droing when arranging in between kidney and the bladder, prevents the emergence of medical malpractice.
The above description is only for the purpose of illustrating the preferred embodiments of the present application and is not intended to limit the scope of the present application, which is within the scope of the present application, except that the same or similar principles and basic structures as the present application may be used.
