- 1030 G-30. 06. 2000 Surgical insert bag

The invention relates to an inflatable surgical insert bag for deployment in the human body, which is inserted after an operation with a lactoscope and preferably counteracts the adhesions of internal organs.

To date, DE 196 00 095 has disclosed a solution in which lactide polymers are used for adhesion prophylaxis. This invention therefore relates to the use of resorbable, physiologically harmless films made of copolymers to prevent postoperative adhesions after surgical interventions. These films made of copolymers are used at a stage in which the operation has taken place and the organs inside the body are completely exposed. The film to be used is then unfolded outside the body and subsequently applied to the

-2-

Surgical wounds are applied to protect them from adhesions.

However, this solution has the disadvantage that, due to its single-layer design, it is not able to adequately prevent adhesions after operations using a laparoscope. The introduction of the single-layer film also requires an additional trocar with instruments and spreading out the film takes a relatively long time, which is why this solution is generally not implemented. In practice, this film cannot unfold to the necessary extent when introduced into the surgical wounds using the laparoscope as a rigid special endoscope.

The invention therefore has the task of creating an effective way of preventing postoperative adhesions after surgical interventions with the laparoscope by means of a surgical insert bag which consists of a two-day surgical insert film. In accordance with the task, no additional working trocar should be required. The surgical insert bag is inserted quickly and without placing any great additional strain on the surgical wound, while still achieving optimal success in preventing postoperative adhesions.
The object of the invention is achieved by the technical features set out in the characterizing part of claim 1.

The invention essentially consists of a two-day surgical insert bag made of preferably copolymers, which is welded or glued on all sides on its outer edges and is equipped with a nozzle provided with a ring in the middle of one of its sides for inflating air. This surgical insert bag equipped in this way

It has a specific fold with subsequent rolling, which takes place from the outside to the inside. The insert bag is rolled up on two sides and is then secured against rolling up by a retaining tab on the top. In this rolled-up state, it is then inserted into the body after the operation has been carried out using a working trocar. Air is then blown into the inflatable insert bag through the air inlet nozzle described above on the upper broad side of the bag using devices known per se, which causes the insert bag to unfold both lengthways and sideways and, when spread out, safely performs its function of preventing post-operative adhesion.

The invention will be explained in more detail below using an exemplary embodiment. The accompanying drawings show:

A single-layer film 1 made of resorbable material, preferably copolymers, is provided with a nozzle 2 in the middle of one of its long sides and is welded or alternatively glued to a second layer of the above-described film 1 on all sides at the edge. However, the nozzle 2 for introducing air into the now formed insert bag as a container is excluded from the welding or gluing. In this way, the single-layer film 1 becomes a flexible container from which all air is removed. A
Fold 3 is made by folding a part of the film 1 in its

long side in the direction of the nozzle 2. The fold 3 is repeated until it has reached the end of the film 1, i.e. the entire body of the insert bag is folded.
The folds 3 to the right and left of the nozzle 2 are then rolled up evenly from both sides towards the nozzle 2 to the middle, i.e. the nozzle 2. The resulting shape of a double roll lying next to each other is pressed together until its cross-section appears circular and reaches a diameter of no more than 9 mm. A holding tab 6 is then applied to the top in the middle, which now keeps both circularly rolled folds 3 in their shape. Finally, after removing the holding tab 6, this insert bag is introduced into the operation area using a working trocar 7 and inflated over the nozzle 2 so that the insert bag, which is made of two identical single-layer films 1, unfolds and in this way reliably prevents adhesions inside the body due to adhesion of the surgical wounds. For the final step in using the insert bag, namely inflating it inside the body, the nozzle 2 is provided with a ring 5 at its end for stabilization and safe handling.

Claims (7)

1. Surgical insert bag, characterized in that it consists of two single-layer resorbable films ( 1 ) which are preferably welded at their longitudinal edges to form an insert bag which is equipped on one of its long sides with a nozzle ( 2 ) for introducing air, the nozzle ( 2 ) having a ring ( 5 ) at its end for safe handling and stabilization. 2. Surgical insert bag according to item 1 , characterized in that the insert bag formed from two single-layer films ( 1 ) has a fold ( 3 ) which is designed with the transverse direction of the insert bag from above in several folds in the direction of the nozzle ( 2 ) and thus runs downwards. 3. Surgical insert bag according to item 2 , characterized in that the insert bag provided with folds ( 3 ) has rolls ( 4 ) which are executed from the outer narrow sides towards the middle in the direction of the nozzle ( 2 ). 4. Surgical insert bag according to items 1 and 3 , characterized in that the two rolls ( 4 ) ultimately have a circular cross-section and are held together at their upper side with a retaining tab ( 6 ) until use. 5. Surgical insert bag according to items 1 and 4 , characterized in that the insert bag is introduced into the body by means of a working troika ( 7 ) after removal of the retaining tab ( 6 ) and is subsequently inflated via the nozzle ( 2 ) and thereby unfolded. 6. Surgical insert bag according to item 1 , characterized in that preferably resorbable and physiologically harmless films made of copolymers are used as the single-layer film ( 1 ) for forming the insert bag. 7. Surgical insert bag according to item 1 , characterized in that the folded and rolled insert bag with a circular cross-section has a maximum diameter of 9 mm.
