The application sleeve can receive a rod-like film carrier onto which is wound the film-like adhesion prophylaxis. For this purpose an elongated, particularly axial reception area, such as a slot is provided in the front area of the sleeve in which the adhesion prophylaxis is received in interlocking or frictional manner. ## Claims ### Claim 1 An instrument for the application of an adhesion prophylaxis for endoscopic surgery, comprising a circular cylindrical application sleeve (10) for introduction into a trocar cannula or for direct introduction into a pneumoperitoneum, said sleeve (10) surrounding a rod-like film carrier (14) receiving a film-like adhesion prophylaxis (22), and an axially elongated reception area (20) at a forward end of the film carrier for receiving and winding up the adhesion prophylaxis (22). ### Claim 2 (depends on 1) An instrument according to claim 1, wherein said reception area (20) is adapted for interlocking and frictional reception of the adhesion prophylaxis (22). ### Claim 3 (depends on 1) An instrument according to claim 1, wherein the reception area (20) comprises an axially directed, elongated slot having a length of about 20 cm and a width of about 0.5 to 2 mm. ### Claim 4 (depends on 3) An instrument according to claim 3, wherein the width of the elongated slot is about 1 to 1.5 mm. ### Claim 5 (depends on 3) An instrument according to claim 3, wherein the application sleeve (10) and the elongated slot (20) are adapted for engaging together longitudinally. ### Claim 6 (depends on 3) An instrument according to claim 3, wherein the film carrier (14) comprises a rod having a total length greater than twice the length of the elongated slot (20). ### Claim 7 (depends on 1) An instrument according to claim 1, wherein a forward end of the film carrier (14) is rounded. ### Claim 8 (depends on 1) An instrument according to claim 1, wherein a seal is provided between the application sleeve (10) and the film carrier (14). ### Claim 9 (depends on 1) An instrument according to claim 1, wherein the film carrier (14) has a front and a rear area (16, 18), wherein the front area (16) is longitudinally slotted (20) and has a smaller external diameter than the rear area (18) and wherein the external diameter of the rear area (18) of the film carrier (14) substantially corresponds to the internal diameter of the application sleeve (10). ### Claim 10 (depends on 1) An instrument according to claim 1, further comprising a trocar cannula into which the instrument is introduced wherein the external diameter of the application sleeve (10) substantially corresponds to an internal diameter of the trocar cannula. ### Claim 11 (depends on 10) An instrument according to claim 10, wherein the application sleeve (10) has a radial, all-round stop region (12) for engagement on a main body of the trocar cannula. ### Claim 12 (depends on 1) An instrument according to claim 1, wherein the reception area comprises a slot. ### Claim 13 (depends on 1) An instrument according to claim 1, wherein bearing surfaces adjustable against one another are formed in the reception area. ### Claim 14 (depends on 13) An instrument according to claim 13, wherein the bearing surfaces comprise toughened surfaces for holding the adhesion prophylaxis.
