Abstract

The utility model relates to an auxiliary instrument in medical surgeries, specifically to a pigtail catheter, comprising two tips curling in opposite directions, with one tip being blind and one tip being open. The pigtail catheter is characterized in that the outer surface of the open tip is provided with a catheter body which is shaped as the letter L. The pigtail catheter facilitates positioning when the open tip is introduced into the urethral canal and enables the introduction angle to be better fixed, and thus solves the problems that it is different to find an inlet at the bleeding opening of the urethral canal and to fix the holding position during introduction of a conventional pigtail catheter even when the inlet is found.

Description

The pigtail conduit

Technical field

This utility model belongs to the assistive device in the medical operating, is specifically related to a kind of pigtail conduit.

Background technology

Pigtail type conduit is also claimed double J pipe, be applied in recent years clinical, mainly solve a variety of causes behind the hydronephrosis and renal pelvis plasty extremely, the kidney hydrops problem behind the operation on ureter and prevent that stricture of ureter from taking place.The structure of pigtail type conduit is that two ends is curled like the pigtail shape in the other direction, and a termination is cecum, and another termination is open, several apertures of sidewall band.The length of curling rear tube is 28-32cm.Because its length is longer; Can not be applicable to coincideing that ureter and wing take off in the kidney transfer operation; Present way is to introduce with a wire guide in the inside of pigtail pipe; But when pigtail was introduced patient's renal pelvis, bad searching intake was prone to elastic deformation take place and walk when introducing because pigtail tubing matter is soft.

The utility model content

This utility model provides a kind of convenient location and the fixing pigtail conduit of introducing angle when the pigtail pipe is introduced urethra, and this pigtail conduit is detachable, easy to operate, reasonable in design in addition.

In order to solve the problems of the technologies described above, this utility model provides following technical scheme: the pigtail conduit, comprise two reverse terminations of curling, and one is cecum, the other end is the open end, described open end outer surface socket conduit, conduit is L-shaped.Because comprise two reverse terminations of curling, one is cecum, the other end is the open end; Described open end outer surface socket conduit, conduit is L-shaped, so when urethra is introduced in the open end of pigtail pipe, conveniently locate; Better fixed the introducing angle of pigtail pipe; Because the opening part at urethra is badly mutilated, be difficult to find accurately inlet, even it is fixing always to have found inlet also to be difficult in when introducing the pigtail pipe holding position.

Further, described conduit and pigtail pipe flexibly connect, and conduit can be dismantled.Because conduit and pigtail pipe flexibly connect; So can be when introducing along with the open end is incorporated into renal pelvis in the open end of pigtail pipe; Handled easily is so again owing to conduit can be dismantled after the pigtail pipe imports renal pelvis and can conduit be taken apart, can alleviate patient's misery like this.

Further, the diameter of described conduit is 8～15mm.Because the diameter according to big young pathbreaker's conduit of the size of the urinary catheter of human body and pigtail pipe reasonably is made as 8～15mm.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done further detailed explanation:

Fig. 1 is the structural representation of this utility model pigtail conduit;

Fig. 2 is the cross sectional representation of this utility model pigtail conduit.

The specific embodiment

As shown in Figure 1: pigtail conduit 1, comprise two reverse terminations of curling, one is cecum 2; The other end is open end 3; Described open end 3 outer surface socket conduits 4, conduit 4 is L-shaped, and is as shown in Figure 2: conduit 4 flexibly connects with pigtail pipe 1; Conduit 4 can be dismantled, and the diameter of conduit 4 is 8～15mm.

During use, find the surgical openings place of urinary catheter earlier, the conduit 4 of the open end 3 of pigtail conduit 1 is inserted opening parts, more whole pigtail pipe 1 is introduced renal pelvis, then the conduit 4 of pigtail is extracted.

Above-described only is the preferred implementation of this utility model; Should be pointed out that for a person skilled in the art, under the prerequisite that does not break away from this utility model structure; Can also make some distortion and improvement; For example: change the diameter of conduit 4, the length of conduit 4, the degree of depth that conduit 4 inserts etc.These also should be regarded as the protection domain of this utility model, and these can not influence effect and practical applicability that this utility model is implemented.

Claims

1. the pigtail conduit comprises two reverse terminations of curling, and one is cecum, and the other end is the open end, it is characterized in that: open end outer surface socket conduit, conduit is L-shaped.

2. pigtail conduit according to claim 1 is characterized in that: described conduit and pigtail pipe flexibly connect, and conduit can be dismantled.

3. pigtail conduit according to claim 1 is characterized in that: the diameter of described conduit is 8～15mm.
