Description

Special clamp for interrupting educational paths in the human or animal organism.

The invention relates to a special clamp for interrupting Pathways in the human or animal organism.

The special clamp according to the invention is preferably made with special pliers held and locked.

For short-term interruption of pathways in the human or animal organism, such as blood vessels, are the most diverse clamping devices used, which are generally outside the body, e.g. during an operation, be attached or only remain inside the body for a short time.

The known clamping devices press the conductor paths to be interrupted together by elastic forces or by mechanical locking held in a position leading to the interruption of the line path in question.

It has now been found that one can get conduction pathways safely and without negative ones Side effects also persistent within the human or animal Can interrupt the organism if a special clamp is used, consisting of two rigid jaws 1 and 2 with parallel; clamping-acting inner surfaces 3 and 4, which at one end by a flexible web 5 and at their other End by a locking mechanism 6 and 7 to be kept on the men. Of the Distance between the inner surfaces 3 and 4 of the clamping jaws 1 and 2 when the clamp is closed is smaller than twice the average wall thickness of the line to be interrupted.

To further increase the safety of interrupting the line path have the inner surfaces 3 and 4 of the clamping jaws 1 and 2 advantageously in the longitudinal direction extending elevations 9 and depressions 8 merging into one another, preferably with when the clamp is closed, all opposing points on the inner surface have the same distances.

The length of the inner surfaces 3 and 4 of the two jaws 1 and 2 is at least as large as half the outer circumference of the line to be interrupted, preferably larger. The width of the inner surfaces 3 and 4 with a clamping effect is preferably as large as half to twice the outer diameter of the one to be interrupted Duct.

According to a preferred embodiment, the flexible web 5 has to connect the two jaws 1 and 2 an incision 10 so that the two cut surfaces touch each other with the clamp closed. Through this is a particularly precise compliance with the desired distance between the two clamping Causes inner surfaces.

The latching device advantageously consists of one over the whole Clamp width extending increased cylindrical part with approach 6 and one corresponding recess 7 in the other jaw.

All edges and corners are to avoid damaging the fabric rounded off the special clamp according to the invention.

The special clamp according to the invention preferably consists of one Corrosion-resistant metal that is stable in the organism, such as stainless steels from Type V2A and V4A. However, it can also be advantageous to use the special clamp after the Invention made of plastics such as polyamides, polycarbonate or other tough to produce biocompatible plastics.

To interrupt a line path 11 in the human or animal Organism is the special clamp in the slightly bent state (see Figure 4) pushed over the line to be interrupted until the middle of the line 11 comes to rest approximately in the middle of the clamp. Then the clamp is careful by pressing the two ends of the clamping jaws 1 and 2 together with the locking devices 6 and 7 closed (Figure 5). In general, the special clamp according to the invention for the permanent closure of pathways in humans or animals Organism used. But you can also have a time-limited closure of such Bring up conductor paths, using special clamps with shallow incisions and easier-to-open latching devices can be used.

For holding, inserting and closing the special clamp after the Invention is preferably a specially designed for this purpose tongs 12 (Figure 6) is used, the arms of which correspond to the outer surfaces of the special clamp, in particular the outer surfaces of the two jaws 1 and 2 are adapted.

Ducts in the human or animal organism, e.g. Fallopian tubes, or vas deferens, have so far been made permanent by cutting through and tying off the free ends of these conductor paths with those commonly used in surgery Threads tied. When the fallopian tubes are interrupted, the opening is the Abdominal cavity and thus a longer inpatient treatment is required. Particularly the healing of the wounds formed when cutting through must be controlled and monitored Post-bleeding in the abdominal cavity can be expected.

With the special terminal according to the invention, for example, the interruption the fallopian tube is brought about particularly easily and permanently without the disadvantages described will.

The special clamp according to the invention is advantageous here by the posterior vaginal vault is inserted with the help of specially designed forceps. In this case, the procedure can be practically painless under local anesthesia can be carried out in a matter of minutes. The main advantage is that there is no wound in the abdominal cavity itself and therefore no secondary bleeding in the fallopian tube must be feared. Compared to the electrical obliteration of fallopian tube sections the interruption of the fallopian tubes with the special clamp according to the invention is more permanent and safer.

The special clamp according to the invention can of course also be used in the course an operation after opening the abdominal cavity to interrupt fallopian tubes will. It is also in the course for the temporary interruption of conduction paths an operation until most of the wound has healed, etc. can be used.

The special advantage of the special clamp according to the invention consists in their small dimensions and their comparatively low weight, whereby the conduction pathways to be interrupted are subjected to as little stress as possible and the tissue in the environment is disturbed as little as possible.

An embodiment of the invention will be based on the following Figures 1 to 6 explained.

Figure 1 shows a longitudinal section through the special clamp; Figure 2 shows a plan view of the special clamp from above; Figure 3 shows a cross section by the special clamp at a --- b according to Figure 1; Figure 4 shows the special clamp in the open state immediately before being pushed over the one to be interrupted Deitungsbahn; Figure 5 shows the special clamp in the closed state with pinched line path; Figure 6 shows a special pair of pliers with inserted Special clamp in the open state.

In the figures, 1 and 2 mean the two rigid jaws of the Special clamp, 3 and 4 the two inner surfaces that have a clamping effect when closed the special clamp. 5 is the flexible web that connects the two clamping jaws 1 and 2. The two clamping jaws are closed by the latching mechanism 6 and 7 State permanently held in clamped position. 8 means running in the longitudinal direction Depressions in the clamping inner surfaces 3 and 4, 9 corresponding elevations, which together represent additional security for interrupting the line path.

The flexible web 5 advantageously has one on its inside Incision 10. 11 represents the one to be interrupted (FIG. 4) or the interrupted one that is clamped off Line path (Figure 5).
