Abstract
The utility model discloses a guide drainage tube of chute straightener, including the drainage tube interior needle file, outer needle file, outer needle tubing and interior needle, interior needle file and outer needle file threaded connection, interior needle is equipped with the drainage groove. The utility model discloses an ingenious cooperation of interior needle and outer needle utilizes the drainage groove that interior needle add for the doctor can be in not extracting can judge whether reach the focus under the condition of needle, has improved diagnosis efficiency, alleviates patient's burden moreover.
Description
Technical field
This utility model belongs to Medical Instruments, particularly a kind of band straightener drainage tube applied clinically
Background technology
One-step method (or step puncture) is the method for intubation of a kind of Fei Saidinggefa, and one-step method is mostly is be applied in PTCD, and conduit can be made under the assistance of ultrasonic image fast and accurately to arrive lesions position.Along with the development of this puncture technique, clinicing aspect has formed two kinds of conventional method of intubation gradually, that is: Sai Dingge and one-step method.One-step method is compared with Sai Dingge, and technical advantage is embodied in the step that can simplify the operation, and when shortening is put effective, coordinates ultrasonic image more can prepare to arrive lesions position, arrives better drainage effect.
One-step method drainage tube conventional on existing market, uses common straightener, needs, by after interior pin extraction, to re-use syringe pumpback to judge whether to arrive focus.This drainage tube not only efficiency is low, and doctor will repeat to implant drainage tube, adds manipulation strength, is unfavorable for patient treatment simultaneously.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of drainage tube once implanting just through focus.
The solution that this utility model solves its technical problem is: the drainage tube of band drainage trough straightener, comprise drainage tube, comprise interior needle stand, outer needle stand, outer needle tubing and interior pin, described interior needle stand is threaded with outer needle stand, and described interior pin is provided with drainage trough.
Conveniently interior pin inserts the use having facilitated drainage trough, the structure of internal pin will be further analyzed, will be described in detail in an embodiment below.
Simultaneously, the design of needle stand also will facilitate practical operation to use, as the further improvement of technique scheme, described interior needle stand is divided into front portion and rear portion, described front portion is provided with external screw thread, and described inside comprises cavity, and the inwall of described cavity is provided with female thread, the centre of cavity is provided with boss, and described interior pin is fixedly connected with boss.
The beneficial effects of the utility model are: this utility model is coordinated with the ingenious of outer pin by interior pin, the drainage trough that in utilizing, pin is set up, making doctor can judge whether when not extracting interior pin to reach focus, improve diagnosis efficiency, and alleviating the burden of patient.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in this utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, instead of whole embodiment, and those skilled in the art, under the prerequisite not paying creative work, can also obtain other designs and accompanying drawing according to these accompanying drawings.
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the amplification front elevation at A place.
Detailed description of the invention
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.Obviously; described embodiment is a part of embodiment of the present utility model, instead of whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite not paying creative work, all belong to the scope of this utility model protection.In addition, all connection/annexations mentioned in literary composition, not singly refer to that component directly connects, and refer to and according to concrete performance, can connect auxiliary by adding or reducing, and form more excellent draw bail.Each technical characteristic in the invention, can combination of interactions under the prerequisite of not conflicting conflict.
With reference to Fig. 1 ~ Fig. 2, the drainage tube of band drainage trough straightener, comprises drainage tube, and comprise interior needle stand 1, outer needle stand 2, outer needle tubing 3 and interior pin 4, described interior needle stand 1 is threaded with outer needle stand 2, and described interior pin 4 is provided with drainage trough 41.Interior pin and outer pin when in use, first combine by doctor, then are inserted in drainage tube and align, when arriving suspected abnormality, can pass through syringe pumpback, congestion flows out from the drainage trough of interior pin, and doctor can judge whether to arrive focus from the congestion of backflow, if do not arrive, then continue to insert, until in-position, whole appliance all will be extracted by the judgement each time avoided in the past, substantially increase therapeutic efficiency, alleviate the burden of patient simultaneously.
Be further used as preferred embodiment, the front end of described interior pin 4 is pointed.The interior pin of point conveniently inserts pumpback congestion.
Be further used as preferred embodiment, described drainage trough 41 is " U " shape.The drainage trough of " U " shape can facilitate the backflow of congestion, and congestion can not be caused to be trapped in groove.
Be further used as preferred embodiment, described interior needle stand 1 is divided into anterior 11 and rear portion 12, and described anterior 11 are provided with external screw thread, described rear portion 12 comprises cavity, the inwall of described cavity is provided with female thread, and the centre of cavity is provided with boss, and described interior pin 4 is fixedly connected with boss.
Be further used as preferred embodiment, the structure of described outer needle stand 2 is identical with the structure of interior needle stand 1.Making identical by interior needle stand with the result of outer needle stand, is conveniently produce, use, and reduces the die sinking cost of enterprise.
Above better embodiment of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite without prejudice to this utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
