Abstract
The invention relates to a nephrostomy tube and an imbedding device, and belongs to the technical field of medical instruments. The nephrostomy tube comprises an isometric tube body with elasticity, and a blocking piece which can locally block a tube opening of the tube body is arranged at one end of the tube body. When the tube is used, a rib-shaped hard long-strip-shaped object stretches into the nephrostomy tube, the hard long-strip-shaped object presses the blocking piece, the elastic action of the tube body is utilized for stretching the tube body and keeping the stretching state, the tube body is stretched into a fistulization kidney, then the stretching state is removed, the elastic tube body restores to deformation, and the fixation of the nephrostomy tube is completed. In the process, the nephrostomy tube becomes thick from thin, therefore, the nephrostomy tube can be naturally compressed on a blood vessel in the expanding type tensioning state, and therefore the hemostasis function is achieved.
Description
Technical field
The present invention relates to a kind of kidney stoma and inserter, belong 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.
Summary of the invention
The present invention will solve the problems of the technologies described above, thereby a kind of haemostatic kidney stoma is provided.
The technical scheme that the present invention 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.
The present invention 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 the present invention 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, rather than 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, rather than necessary.
A further object of the invention is to provide a kind of instrument that above-mentioned kidney stoma is inserted.
Technique scheme of the present invention 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 present invention has following beneficial effect:
The present invention 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 the present invention seems simply, the appearance of this scheme is to be very difficult for, and has obvious technique effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1-body, 2-catch, 3-passage, 4-kidney stoma inserter.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed.
This specific embodiment is only explanation of the invention, is not limitation of the present invention.Any modification that those skilled in the art have done after having read description of the present invention, 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.
Kidney stoma inserter 4 is the long strip shape object of body 1 diameter described in a diameter <, the length of body 1 described in the length > of kidney stoma inserter 4.
