Abstract

The utility model relates to a nephrostomy tube and an implantation device, and belongs to the technical field of medical instruments. The nephrostomy tube comprises an elastic equal-diameter tube body, and a blocking sheet for partially blocking a tube opening of the tube body is arranged at one end of the tube body. When the nephrostomy tube is used, a hard strip-shaped object in an umbrella rib shape is stretched into the nephrostomy tube, the hard strip-shaped object is made to abut against the blocking sheet, the tube body is stretched through the elastic function of the tube body, the stretched state is kept, the tube body is stretched into the fistulization kidney, then the stretched state is removed, the elastic tube body resets and is deformed, and the nephrostomy tube is fixed. In the process, the nephrostomy tube becomes thick from thin, the nephrostomy tube can be naturally compressed on the blood vessel in a tensioned state, and therefore the function of stopping bleeding is achieved.

Description

Kidney stoma and inserter

Technical field

This utility model relates to a kind of kidney stoma and inserter, belongs to technical field of medical instruments.

Background technology

Renal calculus is a kind of common disease, when treatment, needs only calculus is taken out.When calculus hour can adopt laser lithotripsy method, be broken into and can flow out with urine after fritter externally, lithiasis is recover for illness without medical help.If calculus is larger, laser lithotripsy method is ineffective.Cut open kidney if open abdomen, very big to patient trauma.In existing medical skill, there is a kind of ultrasonic locatization, utilize ultrasound wave to search out calculus place.Know behind calculus place, medical skill superb doctor be very easy to just can calculus be taken out by the method for kidney fistulation.So kidney fistulation not only has requirement for medical skill, and dangerous part is also postoperative hemorrhage.A common doctor's kidney fistulation level height, is not to be calculus to be taken out by fistulation, and depends primarily on postoperative bleeding.In prior art, there is compression method for hemorrhage processing, as Sengstaken-Blakemore tube.It is to adopt pouch to inflate vascular compression, thereby blood is stopped, but this method be not suitable for the hemostasis after nephrostomy.

Utility model content

This utility model will solve the problems of the technologies described above, thereby a kind of haemostatic kidney stoma is provided.

The technical scheme that this utility model addresses the above problem is as follows:

Kidney stoma, comprises and has elastic isometrical body, and described body one end is provided with the catch of tube mouth described in partial occlusion.

This utility model in use, by the hard long strip shape object (hereinafter to be referred as umbrella frame) of shape as umbrella frame, stretch into kidney stoma inside, umbrella frame top is pressed in to described catch, utilizes the elastic reaction of body that body is stretched, keep extended state, stretch in the kidney of fistulation, then remove this state, resilient body is replied deformation, and kidney stoma completes set.In this process, kidney stoma, by thin chap, just can be oppressed on blood vessel with the tensioning state of expansion type naturally, thereby has the function of hemostasis.Although this utility model seems simply, the appearance of this scheme is to be very difficult for, and has obvious technique effect.The inventor is urological associate chief physician, this scheme has been put into practice in working at ordinary times for more than 10 times, and postoperative do not have a hemorrhage situation.

As technique scheme preferably, described catch is to described body outer lug.

As technique scheme preferably, between described catch and described body, there is passage.

As technique scheme preferably, described passage has two, is symmetric with respect to described body.

As technique scheme preferably, the diameter of the width≤described body of described catch.

As technique scheme preferably, if the diameter of body is r, the length L EssT.LTssT.LT 2 π r of π r≤described catch.

As technique scheme preferably, when described catch is stressed, the amount of elastic deformation of body described in the amount of elastic deformation < of catch.If the amount of elastic deformation of the amount of elastic deformation > body of catch, in the time stretching, deformation mainly occurs in catch, and the deformation quantity of body is little, this oppresses the dynamics on blood vessel with the tensioning state of expansion type after may affecting body set, thereby affects haemostatic effect.But the amount of elastic deformation of body described in the amount of elastic deformation < of catch, be not say state phenomenon be bound to occur.Inventor adopts " the T-shaped T-type drainage tube of disposable use latex " in operation at ordinary times, and T-shaped part is cut off, and surplus next catch, has symmetrical passage naturally between catch and body.In this technical scheme, catch is consistent with the elasticity of body, but does not hinder postoperation hemostatic completely.Therefore, those skilled in the art have reason to believe, the amount of elastic deformation of the catch slightly amount of elastic deformation of > body also can realize above-mentioned purpose.Therefore, when the amount of elastic deformation of the amount of elastic deformation > body of catch, may there is above-mentioned disadvantageous situation, instead of the situation that must occur.Therefore, the amount of elastic deformation of body described in the amount of elastic deformation < of catch, should be considered as preferably a kind of, instead of necessary.

This utility model also has an object to be to provide a kind of instrument that above-mentioned kidney stoma is inserted.

This utility model technique scheme is as follows:

Kidney stoma inserter, described inserter is the long strip shape object of a diameter < kidney stoma pipe diameter, the length of the length > kidney stoma body of described inserter.

The utlity model has following beneficial effect:

This utility model in use, by the hard long strip shape object (hereinafter to be referred as umbrella frame) of shape as umbrella frame, stretch into kidney stoma inside, umbrella frame top is pressed in to described catch, utilizes the elastic reaction of body that body is stretched, keep extended state, stretch in the kidney of fistulation, then remove this state, resilient body is replied deformation, and kidney stoma completes set.In this process, kidney stoma, by thin chap, just can be oppressed on blood vessel with the tensioning state of expansion type naturally, thereby has the function of hemostasis.Although this utility model seems simply, the appearance of this scheme is to be very difficult for, and has obvious technique effect.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is further detailed.

This detailed description of the invention is only to explanation of the present utility model, is not to restriction of the present utility model.Any amendment that those skilled in the art have done after having read description of the present utility model, as long as in the protection domain of claim, all will be subject to the protection of Patent Law.

As shown in Figure 1, kidney stoma, comprises and has elastic body 1, described body 1 one end has the catch 2 being connected with described body 1, between described catch 2 and described body 1, is formed with passage 3.The diameter of body 1 described in the width < of described catch 2.If the diameter of body 1 is r, the length L EssT.LTssT.LT 2 π r of π r≤described catch 2.The elasticity of the elasticity=catch 2 of body 1.
