Abstract

The invention relates to a device for intracorporeal application of auxiliary medical material, in particular for bio-materials and wound applications, having a hollow application tube for inserting the auxiliary medical material into the surgical area. To create a device for intracorporeal application of auxiliary medical material that ensures simple handling and a secure application of the auxiliary medical material in the surgical area, the invention is characterized by a winding insert that can be inserted into the hollow application tube and can be slid in the longitudinal direction of the application tube and on which it is possible to wind the auxiliary medical material that is to be applied.

Claims

1. A device for intracorporeal application of an auxiliary medical material, the device comprising:

a hollow application tube for inserting the auxiliary medical material into a surgical area, the application tube having at least one window thereon, wherein the at least one window is spaced away from a distal opening of the application tube; and

a winding insert configured to be inserted into the application tube, the winding insert having a distal portion onto which the auxiliary medical material is wound and a proximal portion that comprises a various catch steps, the various catch steps being spaced apart from each other in an axial direction of the winding insert such that each catch step marks a corresponding working step and a particular insertion depth of the winding insert inside the hollow application tube;

wherein the application tube and the winding insert are configured such that;

i) at a first catch step and a first corresponding working step, the auxiliary medical material can be inserted through the at least one window to wind onto the winding insert while the distal portion is completely inside the application tube;

ii) at a second catch step and a second corresponding working step, the distal portion is inserted distally farther into the application tube than at the first catch step and the auxiliary medical material cannot be unwound through the at least one window; and

iii) at a third catch step and a third corresponding working step, the distal portion and the auxiliary medical material extend through the distal opening of the application tube.

2. The device according to claim 1, wherein the application tube defines a longitudinal axis and wherein the winding insert, when inserted into the application tube, can be rotated within the application tube about the longitudinal axis.

3. The device according to claim 2, wherein the auxiliary medical material can be affixed onto the winding insert.

4. The device according to claim 1, wherein the auxiliary medical material can be affixed onto the winding insert.

5. The device according to claim 4, wherein a slit is configured in the winding insert for receiving one end of the auxiliary medical material.

6. The device according to claim 4, wherein a slit is configured to traverse entirely through the winding insert for receiving the auxiliary medical material.

7. The device according to claim 1, wherein the winding insert, at least in the distal portion, is configured as a wire pin that can be inserted into the application tube.

8. The device according to claim 1, wherein the at least one window extends in an axial direction on the application tube.

9. The device according to claim 8 wherein the at least one window comprises two axially-extending windows on diametrically opposite sides of the application tube.

10. The device according to claim 1, further comprising a handle positioned on the proximal end of the application tube and of the winding insert.

11. The device according to claim 1, wherein the auxiliary medical material consists of a mesh bio-material for a hernia operation.

12. The device according to claim 1, wherein the auxiliary medical material that is to be applied comprises bio-materials or wound applications.

13. The device according to claim 1, further comprising a handle positioned on the proximal end of the application tube or of the winding insert.
