Drainage

 

(57) Abstract:

The invention relates to medicine, namely to purulent surgery. The technical result of the invention is improving the efficiency of the sealed drainage of abscesses. The drainage consists of suction and multiple irrigation tube with side holes located in different planes relative to the longitudinal axis of the suction tube. One end of each of the irrigation tube is plugged and fixed to the working end of the suction tube, and the opposite is placed on its outer surface with the possibility of reciprocation and the formation of a loop variable area on its working end. Positional stability of the drainage system is achieved by shunting one or more loops formed irrigation tubes commensurate with them flexible core. 3 Il.

The invention relates to medicine, namely to purulent surgery.

Known drainage device containing the irrigation and suction tube with side holes, and the irrigation tube in the middle segment forms a loop before the working end of the suction tube, and its available capacity mutual reciprocating movement of the suction and irrigation tubes /SU A. C. N 1410990, A 61 M 27/00 - similar, he is the prototype/.

The described device has the disadvantage of low positional stability, nepozvoljaet securely fix the drainage in a tightly closed abscess, preventing its spontaneous or unplanned migration, for example, when the forced change of the area of the loop of the irrigation tube. In addition, the location of the segments of the irrigation tube in the lumen of the suction reduce the useful working the last section, which reduces the efficiency at the "closed" drainage secuestradores zones of destruction, such as pancreatic character.

The objective of the invention is improving the efficiency of the sealed drainage of abscesses.

The problem is solved by the fact that the irrigation tube drainage performed in multiple different planes along the longitudinal axis of the suction tube, each one plugged end rigidly fixed to the working end of the suction tube and free - placed coaxially in a semi-closed slots on the outer surface of the latter with the possibility of reciprocation and the formation of the working end of the suction tube reset system is achieved by introducing into one or more irrigation tubes throughout their length commensurate with flexible mobile core.

In Fig. 1 shows a General view of the proposed drainage:

1 - suction tube with side holes;

2 - irrigation tube with side holes;

3 - "muted" the end of the irrigation tube;

4 - the free end of the irrigation tube;

5 - the loop variable area irrigation tube;

6 - semi-closed slot of the suction tube;

7 - flexible movable core;

8 - retainer clip.

In Fig. 2 is a longitudinal section of the proposed drainage along the irrigation hinges with locking flexible movable core.

In Fig. 3 - stages of installation of drainage into the cavity of the abscess:

9 - initial position, the irrigation pipe as drawn in semi-closed slots of the suction tube;

10 - working position in one of the formed irrigation loops introduced a flexible movable core.

The device is used as follows.

In the cavity revealed abscess surgery or using minimally invasive technologies /for example, under control of the ultrasonic scan/ create access, commensurate with applicable drainage. Through the access cavity destruction introduces the proposed drainage louvetot the provisions of the drainage of purulent cavity is controlled by sonography and /or/ radiographically. Then, creating a force on the free end of the irrigation tube 2, is injected into the drained cavity, creating raznovozrastnye irrigation loop 5 before working end of the suction tube 1. After that, one or two irrigation tube 2 are inserted flexible cores 7, splinting a selected irrigation loops 5, which creates a customized according to the size and geometry of the drained area of destruction of the system of fixing, stabilizing suction tube 1 in the selected position. Mutual mobility of the core 7 and the irrigation tube 2 is fixed retainer clip. When this flow of flushing fluid into the cavity of the destruction is carried out through the remaining free irrigation tube 2 and the outflow through the suction tube 1. In the process of treatment according to the results of sonography and x-ray examinations are changing the area of retention and leaching irrigation loops 5, and if necessary change them together.

An example of a specific application.

Patient M., 49, history N 10281, was admitted to the Department of purulent surgery Bureau N1 23.06.98 with a diagnosis of Nobiliary pancreonecrosis, left-sided retroperitoneal abscess. Ultrasonography revealed accuzone exudation, usual semi-rigid J-conductor, dilatational system bogey and created percutaneous access with a diameter of 11 mm. wound channel in the cavity of destruction initiated the proposed device in the assembled state is maximally retracted irrigation tubes. Under sonographic control the selected optimum position of the drainage cavity destruction. After that, making the effort consistently for all three irrigation pipes of the drainage system, were formed raznovozrastnye irrigation loops in the area of the working end of the suction tube. Then in one of the tubes has introduced flexible proportionate to the core to stiffen the drainage system, while the core has executed a selected irrigation loop, and at the free end of the irrigation tube it was fixed with a clip. Drainage was slightly improved for the suction tube to the feeling of elastic resistance through the locking loop and attached to the skin. Wash liquid is introduced through the free ends of the two nesinervink irrigation tubes, and was utekala through the side holes on the suction pipe of the drainage system. When this drainage is freely leave not only the liquid pus, and tissue sequesters. Long trenirovka the stable position the entire period of drainage.

The drainage containing the irrigation and suction tube with side holes, and the irrigation tube forms a loop variable square in front of the working end of the aspiration tube, wherein the irrigation tube drainage performed in multiple different planes along the longitudinal axis of the suction tube, each one plugged end rigidly fixed to the working end of the suction tube and freely - placed coaxially on the outer surface of the latter with the possibility of reciprocation, and the positional stability of the system is achieved by introducing into one or more formed irrigation tubing loops over the entire length commensurate with flexible mobile core.
