Abstract

Consistent with an aspect of the present disclosure, a mesh or other surgical material is wrapped about one or more shafts, and inserted into a body cavity where it is unfurled and placed over a tissue site, such as a hernia. The mesh, for example, is secured to the shaft in order to prevent crimping or crumpling thereof during deployment over the tissue site.

Claims

1. A surgical tool comprising:

a sheath having an opening, the opening extending along a length of the sheath, the sheath having an inner surface defining a cavity; and

a shaft, the cavity of the sheath being adapted to receive the shaft and a material disposed about the shaft, the shaft having surface; and

a plurality of protrusions extending from the surface of the shaft, the plurality of protrusions being provided at a plurality of locations along a length of the shaft, the plurality of protrusions being configured to grip a first portion of the material, wherein, upon rotation of the shaft within the cavity, a second portion of the material is output from the opening for application to a biological tissue.

2. A surgical tool in accordance with claim 1, wherein the each of the plurality of protrusions has a rounded shape.

3. A surgical tool in accordance with claim 1, wherein each of the plurality of protrusions has a conical shape.

4. A surgical tool in accordance with claim 1, further including a handle attached to an end portion of the shaft, the handle being configured to be gripped by a user to facilitate said rotation of the shaft with the cavity.

5. A surgical tool in accordance with claim 1, wherein the shaft includes metal.

6. A surgical tool in accordance with claim 1, wherein the shaft includes plastic.

9. A surgical tool in accordance with claim 1, wherein the material constitutes a mesh.

10. A surgical tool in accordance with claim 1, wherein first ones of the plurality of protrusions are linearly arranged in a first row provided on a first side of the shaft and second ones of the plurality of protrusions are linearly arranged in a second row provided on a second side of the shaft.

11. A surgical tool in accordance with claim 10, wherein the first side of the shaft is opposite the second side of the shaft.

12. A surgical tool in accordance with claim 1, further including a trocar, the trocar having an opening configured to receive at least a portion of the sheath and a portion of the shaft.

7. A surgical tool in accordance with 4, wherein the end portion is a first end portion, the shaft having a second end portion provided opposite the first end portion, the second portion having a rounded shape that protrudes in a direction away from the first end portion.

8. A surgical tool in accordance with 4, wherein the end portion is a first end portion, the shaft having a second end portion provided opposite the first end portion, the second portion having a conical shape that protrudes in a direction away from the first end portion.

13. A surgical tool comprising:

a first shaft;

a second shaft spaced from the first shaft by a gap, the gap being configured to receive a first portion of a material;

a first member having first and second recessed portions, the first recessed portion configured to receive a first end portion of the first shaft, and the second recessed portion configured to receive a first end portion of the second shaft;

a second member having first and second recessed portions, the first recessed portion of the second member being configured to receive a second end portion of the first shaft, and the second recessed portion of the second member being configured to receive a second end portion of the second shaft, the first end portion of the first shaft being opposite the second end portion of the first shaft, and the first end portion of the second shaft being opposite the second end portion of the second shaft; and

a sheath having an opening, the opening extending along a length of the sheath, the sheath having an inner surface defining a cavity, the first and second shafts being provided in the cavity,

wherein, upon rotation of the first shaft, a second portion of the material is provided through the gap between the first and second shafts for application to a biological tissue.

14. A surgical tool in accordance with claim 13, further including a handle attached to an end portion of the shaft, the handle being configured to be gripped by a user to facilitate said rotation of the first and second shafts within the cavity.

15. A surgical tool in accordance with claim 13, wherein the shaft includes metal.

16. A surgical tool in accordance with claim 13, wherein the shaft includes plastic.

19. A surgical tool in accordance with claim 13, wherein the material constitutes a mesh.

20. A surgical tool in accordance with claim 13, further including a trocar, the trocar having an opening configured to receive at least a portion of the sheath and a portion of the shaft.

31. A surgical tool in accordance with claim 13, wherein the first shaft extends along a first longitudinal axis and the second shaft extends along a second longitudinal axis, the first shaft having a first cross-sectional area which is transverse to the first longitudinal axis and the second shaft having a second cross-sectional area which is transverse to the second longitudinal axis, the first cross-sectional area being greater than the second cross-sectional area.

17. A surgical tool in accordance with 14, wherein the end portion is a first end portion, the shaft having a second end portion provided opposite the first end portion, the second portion having a rounded shape that protrudes in a direction away from the first end portion.

18. A surgical tool in accordance with 14, wherein the end portion is a first end portion, the shaft having a second end portion provided opposite the first end portion, the second portion having a conical shape that protrudes in a direction away from the first end portion.

21. A surgical tool comprising:

a sheath having an opening, the opening extending along a length of the sheath, the sheath having an inner surface defining a cavity; and

a shaft, the cavity of the sheath being adapted to receive the shaft and a material disposed about the shaft, the shaft having surface; and

a plurality of bristles extending from the surface of the shaft, the plurality of bristles being configured to grip a first portion of the material, wherein, upon rotation of the shaft within the cavity, the material is output from the opening for application to a biological tissue.

22. A surgical tool in accordance with claim 21, further including a handle attached to an end portion of the shaft, the handle being configured to be gripped by a user to facilitate said rotation of the shaft with the cavity.

23. A surgical tool in accordance with claim 21, wherein the shaft includes metal.

24. A surgical tool in accordance with claim 21, wherein the shaft includes plastic.

27. A surgical tool in accordance with claim 21, wherein the material constitutes a mesh.

28. A surgical tool in accordance with claim 21, wherein first ones of the plurality of bristles are linearly arranged in a first row provided on a first side of the shaft and second ones of the plurality of bristles are linearly arranged in a second row provided on a second side of the shaft.
