Device for dewatering of hollow organs

 

(57) Abstract:

The invention is used in medical equipment, namely to drain cavities in diseases of the biliary or urinary tract. The technical result of the invention is to provide a simple construction of the device with improved operating conditions. Device for dewatering of hollow organs contains a flexible tube serving with working part of smaller diameter. On insertion into a hollow organ end of the flexible tube has a longitudinal slot and the ability to move relative to the protruding part. Coaxially with the tube located stiletto with pointed end and the locking element. On the stiletto freely placed the adapter connected to the distal end of the flexible tube with one hand, and on the other with the housing locking element rigidly connected with the stiletto. Fixation was performed with a figure of the tracing of the groove made on the body of the locking element and the pin located on the adapter. The sharp end of the stiletto executed with a possibility of occurrence of an interference in working protruding part of the tube. 2 Il.

The invention relates to medical equipment, namely, devices for drainage of paloich bodies C.UK N 1463269, A 61 M 25/00, Appl. 15.11.74,, publ. 02.02.1977,

The device comprises two coaxially arranged flexible hollow tube rigidly connected to one another at the working end, and the outer tube has a longitudinal slot and the ability to move relative to the inner tube.

The device does not provide a secure fixing of the tubes, which leads to damage and leaks puncture holes.

As the prototype is set to "Device for drainage of hollow organs".with. USSR N 1537231, MCI: A 61 B 17/34, A 61 M 27/00, Appl. 30.12.86,, publ. 23.01.90, the Device comprises two coaxially arranged flexible hollow tube rigidly connected to one another at one end, and the outer tube has a longitudinal slot and the ability to move relative to the inner tube at the point of contact with the outer tube in the protruding portion, the latch relative position of the tubes, freely located on the outside end of the inner tube, with working part of the inner tube stands for the place of its rigid attachment to the outer tube. The device is equipped with auxiliary latch that is located on the outside of the tube. In the inner tube impose sharp metal article is PA:

- the presence of two tubes, two retainers of their mutual arrangement complicates the design of the device, and the stiletto out of the structure during operation inconvenience.

The present invention is to provide a simplified device for drainage of hollow organs with upgraded amenities operation.

To solve the problem in the device for drainage of hollow organs, containing a flexible tube serving with working part of smaller diameter, having a longitudinal slot for insertion into a hollow organ end and the ability to move relative to the protruding part, coaxially located with the tube stiletto with pointed end and the locking element according to the invention the inner diameter of serving the working part is less than the internal diameter of the tube, the stiletto on the non-working end rigidly connected to the housing of the locking element, and tapered end made with the possibility of entering into working protruding part of the tube with an interference fit when the locking element is equipped with an adapter, posted by the stiletto can travel to interact with non-working end of the flexible tube with one hand and fixation on the body with the other hand.

Rigid connection outside part of the stiletto with the housing locking element and the presence of adapter that communicates with the outside end of the flexible tube with one side housing the locking element on the other hand creates a monolithic design ensures simple, convenient operation with the introduction of the device into the hollow organ.

A search showed the absence of similar solutions and allowed to conclude that the claimed design is not clear from the investigated prior art, i.e., it meets the criterion of "novelty" and "inventive step".

The inventive device may find application in medicine for drainage of hollow organs in diseases of the biliary and urinary tracts, i.e., meets the criterion of "industrial applicability".

The essence of the claimed technical solution is illustrated by drawings, where Fig. 1 shows the device in the initial position; Fig.2 - the same, in working condition.

Ostrer working part 2 is less than the internal diameter of the flexible tube 1. To enter in the full body of the end of the flexible tube is made of longitudinal slots 3. Coaxially with the tube 1 is placed stiletto 4 with a pointed end, which is clamped installed in the protruding working piece, creating a hard contact against which in the initial position, the longitudinal stretching of the walls of the flexible tube in a smooth surface, and with the exception of the contact resulting from the removal of the tube stiletto in the area of the slots due to elastic deformations occur bulging walls and education "umbrella" - the release of the working part.

The non-working end of the stylet 4 is rigidly connected to the housing 5 of the locking element 6. The locking element 6 is supplied with the adapter 7, freely mounted on the stylet 4.

The adapter 7 with one side threaded for engagement with the connecting element 8 is placed on the outside end of the flexible tube 1. The other end of the adapter 7 is installed with the possibility of entering into the housing 5 of the fixed element 6: case 5 in the front part is made in the form of a sleeve, provided with cross-cutting curly tracing a groove 9 for engagement with a pin 10 mounted on the second end of the adapter 7. The rear end of the housing 5 of the locking element 6 vypolneniem at the point of the proposed injection device is a notch leather length 0.5 cm; under the control of the laparoscope or ultrasonic device the device is inserted into the abdominal cavity. Connecting the adapter 7 with the housing locking element 6, the stylet 4, rigidly connected with the latter being tightly fitted into the inner working part 2 of the flexible tube 1, pulls the longitudinal elastic tube wall in place of the longitudinal slots 3 in smooth, without protrusions surface. In this folded (initial) position of the device smoothly injected into the hole of the cavity, punctured coming out of the tube 1 the pointed end of the stylet 4.

After the end of the tube 1 with longitudinal slots 3 will be in the lumen of a hollow organ, form lock ("umbrella") of the working part. Stiletto 4 block 5 of the locking element 6 and the adapter 6 are derived from the flexible tube 1. In the region of the longitudinal slots 3 in the elastic deformation of the wall of the flexible tube going with the formation of the release of the working part. The distal end of the flexible tube 1 is stitched to the skin. Ensures free flow of bile.

To remove the flexible tube 1 from the hollow body of the device lead to the initial position: the adapter 7 is connected with a non-working end of the flexible tube 1. Stiletto to the housing 5 of the clamping element 6 is introduced into the flexible tntc") is formed and the device is easily removed from the body.

Introduction in the hollow body of the device by means of stiletto rigidly connected with the housing, the locking element and freely mounted on the stylet adapter that communicates with a flexible tube at its distal end and the housing locking element, provides a simple, convenient operation, monolithic structure.

The use of the proposed device allows drainage of hollow organs with reliable fixation and sealing.

Device for dewatering of hollow organs, containing a flexible tube serving with working part of smaller diameter, having a longitudinal slot for insertion into a hollow organ end and the ability to move relative to the protruding part, coaxially located in the tube stiletto with pointed end and the locking element, wherein the inner diameter serving the working part is less than the internal diameter of the tube, the stiletto on the non-working end rigidly connected to the housing of the locking element, and a pointed end made with the possibility of joining with tightness in working protruding part of the tube, while the locking element is equipped with an adapter, posted by the stiletto can travel for mutual
