Abstract
The present invention relates to a kind of kidney stoma and inserter, belong to technical field of medical instruments.Kidney stoma, comprise and have elastic isometrical body, 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 of such as shape as umbrella frame, stretch into kidney stoma inner, hard long strip shape object top is pressed in described catch, utilizes the elastic reaction of body to be stretched by body, keep extended state, stretch in the kidney of fistulation, then remove this state, resilient body replys deformation, and kidney stoma completes set.In the process, kidney stoma, by carefully thicker, just with the compressing of the tensioning state of expansion type on blood vessel, thus can have the function of hemostasis naturally.
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, as long as calculus is taken out during treatment.Can adopt laser lithotripsy method when calculus is less, can flow out external with urine after being broken into fritter, then lithiasis is recover for illness without medical help.If calculus is comparatively large, then laser lithotripsy method is ineffective.If open abdomen to cut open kidney, then very big to patient trauma.In existing medical skill, there is a kind of ultrasonic locatization, namely utilize ultrasound wave to search out calculus place.After knowing calculus place, the superb doctor of medical skill is then very easy to just calculus be taken out by the method for kidney fistulation.Right kidney fistulation not only has requirement for medical skill, and dangerous part is also postoperative hemorrhage.The kidney fistulation level height of a usual doctor, is not be calculus to be taken out by fistulation, and depends primarily on postoperative bleeding.In prior art, there is compression method, as Sengstaken-Blakemore tube for hemorrhage process.It adopts pouch inflation to carry out vascular compression, thus stopped by blood, but this method hemostasis after not being suitable for nephrostomy.
Summary of the invention
The present invention will solve the problems of the technologies described above, thus provides a kind of haemostatic kidney stoma.
The technical scheme that the present invention solves the problem is as follows:
Kidney stoma, comprise and have elastic isometrical body, 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 referred to as umbrella frame) of such as shape as umbrella frame, stretch into kidney stoma inner, umbrella frame top is pressed in described catch, utilizes the elastic reaction of body to be stretched by body, keep extended state, stretch in the kidney of fistulation, then remove this state, resilient body replys deformation, and kidney stoma completes set.In the process, kidney stoma, by carefully thicker, just with the compressing of the tensioning state of expansion type on blood vessel, thus can have the function of hemostasis naturally.Although the present invention seems simple, the appearance of the program is very not easily, and has obvious technique effect.The present inventor is urological associate chief physician, and in working at ordinary times, this scheme has been put into practice more than 10 times, postoperative do not have hemorrhage situation.
Preferred as technique scheme, described catch is to described body outer lug.
Preferred as technique scheme, has passage between described catch and described body.
Preferred as technique scheme, described passage has two, is symmetric relative to described body.
Preferred as technique scheme, the diameter of the width≤described body of described catch.
Preferred as technique scheme, if the diameter of body is r, then the length < 2 π r of π r≤described catch.
Preferred as technique scheme, 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, then when stretching, deformation mainly occurs in catch, and the deformation quantity of body is little, this dynamics of oppressing on blood vessel with the tensioning state of expansion type after may affecting body set, thus affect 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 single use latex " in operation at ordinary times, T-shaped part is cut off, and surplus next catch, has symmetrical passage between catch and body naturally.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 amount of elastic deformation summary > body of catch also can realize above-mentioned purpose.Therefore, during the amount of elastic deformation of the amount of elastic deformation > body of catch, above-mentioned disadvantageous situation may be there is, 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 necessity.
A further object of the invention is to provide a kind of instrument of being inserted by above-mentioned kidney stoma.
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 referred to as umbrella frame) of such as shape as umbrella frame, stretch into kidney stoma inner, umbrella frame top is pressed in described catch, utilizes the elastic reaction of body to be stretched by body, keep extended state, stretch in the kidney of fistulation, then remove this state, resilient body replys deformation, and kidney stoma completes set.In the process, kidney stoma, by carefully thicker, just with the compressing of the tensioning state of expansion type on blood vessel, thus can have the function of hemostasis naturally.Although the present invention seems simple, the appearance of the program is very not easily, 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.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed.
This detailed description of the invention is only explanation of the invention, is not limitation of the present invention.Any amendment that those skilled in the art are 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, and described body 1 one end has the catch 2 be connected with described body 1, is formed with passage 3 between described catch 2 and described body 1.The diameter of body 1 described in the width < of described catch 2.If the diameter of body 1 is r, then the length < 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.
