Abstract
Instrument for use at the applying of branching on vessel by means of anastomosis rings in order to prevent constrictions in the joint area, which is T-shaped, the vertical part of the T being constituted by an unyielding pipe (1) or hose whereas the upper part (3) of the T is elastic. The upper part of the T constitutes a closed space but for a connection with the vertical hose or pipe. The upper part of the instrument can in evacuated state be inserted through a cut in a vessel wall, then to be blown up to expand the vessel, before an anastomosis end to side is conducted by means of an anastomosis ring.
Description
Instrument for prevention of constrictions in the joint area at the appliance of branching on vessel
In the vessel surgery it has become increasingly useful with by-passes, i.e. for instance constricted vessel are replaced by healthier ones that are coupled in parallel or that vessels are connected at other places than originally. Up till now one has used the technique of sewing the vessels together by means of sutures. It has however been found that anastomosis rings can be used to make anastomosis "end to side". When this is done the vesse that is to be branched off is punctuated by a small cut tha is then flared and the vessel is placed over the pins of th anastomosis ring. In this way it is possible to make the branching or by-passing considerably faster than with a conventional sewing technique. In this way the resources are better used and the risks for the patient are di inshed Regretfully this way of conducting an end to side operation is not entirely without draw-backs. It has namely been found that the applying of the anastomosis ring so to say steals material from the vessel to which the branching is coupled and results in a constriction which definitely is undesirable since the by-pass is applied in order to improve the flow. In view of this problem the invention has as it's object to provide an instrument eliminating this draw-back.
In accordance with the invention these problems are solved by means of a T-shaped instrument where the upper part of the T in principal is constituted by an el-stically expandable part that in the most simple case can be""consti- tuted by a piece of a thin-walled hose,thevertical part of the T being constituted by another hose connected with a pressure source. This pressure source can for instant be a common injection syringe. By proλiding a medium under pressure to the elastic upper part of the T this can be expanded and by evacuating this part it can also be made
very thin and easy to handle. At use the upper parts of the T are each inserted in different directions in the vessel through the little cut w'here the branching is to be placed. When the parts of the T re well inserted into the vessel they are expanded and the vessel is expanded to about twice of it's original dia etre. The instrument is then evacuated and removed from the vessel and an anastomosis ring and the additional vessel end can be connected. Since the vessel is not entirely elastic it will retain it's expansion for sufficient time to secure that no constric¬ tion occure despite the use of an anastomosis ring for the connection. Tests have shown that no tendency whatever prevail for a rupture or a tearing of the cut in the vessel during the expansion of this. The reason for this may be the very uniforme stress that the vessel is subjected to in comparison with what would be the case if one tries to expand the vessel by means of pincettes or the like.
The invention is below to be described in connection with the drawing, where fig. 1 shows an embodiment in accor- dance with the invention seen from the side at rest and fig. 2 the same instrument seen from the side and fig. 3 shows the instrument in it's so to say working state.
The instrument shown in fig. 1 is constituted by a thick-wralled connection hose 1 of plastic, which has been welded to a side-opening 2 in. a thin-walled elastic plastic hose 5. This hose 3 is furthermore at it's ends 4 and 5 welded together. The hose 1 is very thin, and has preferably such a diameter that it fits on the tip,7of..an injection syringe. In fig. 3 finally the instrument has .been subjected to pressure resulting in that the thin-walled upper part of the instrument has been expanded.
On the drawing the instrument is of course
en¬ larged, in reality the diameter of the connection hose 1 is about 1 mm whereas "the balloonpart" has a diameter of about 2 mm and the length of this upper balloonpart is about 8 mm
in unaffected state. Finally it should be mentioned that the instrument is very hygenic and economic to produce.
