Abstract

A surgical tool assembly includes a pair of opposing jaws pivotally connected to each other. Further, at least one viewing opening may be provided in at least one of the opposing jaws. In this regard, the at least one viewing opening may extend from an upper to a lower surface of the opposing jaw in which the viewing opening is provided. Additionally, the at least one viewing opening may include a material retainer provided proximate the lower surface of the opposing jaw in which the at least one viewing opening is provided. Further, the material retainer may include an inclined surface inclined towards a central axis of the at least one viewing opening. Further, a grasping insert may be molded onto a lower surface of the opposing jaw in which the viewing opening is provided and an elastomeric material of the grasping inserts may within the at least one viewing opening, the material of the grasping inserts covering the inclined surface of the first material retainer.

Claims

1. A surgical tool assembly comprising:

a pair of opposing jaws pivotally connected to each other;

at least one viewing opening provided in at least one of the opposing jaws, the at least one viewing opening penetrating through an upper and lower surface of the opposing jaw in which the viewing opening is provided, the at least one viewing opening having a material retainer provided at the lower surface of the opposing jaw in which the at least one viewing opening is provided, the material retainer comprising an inclined surface inclined towards the at least one viewing opening, and the material retainer being positioned at an inner periphery of the at least one viewing opening; and

an elastomeric grasping insert molded onto the lower surface of the opposing jaw in which the viewing opening is provided, wherein a material of the grasping inserts extends within the at least one viewing opening and covers the inclined surface of the material retainer,

wherein the opposing jaw in which the at least one viewing opening is provided comprises;

a first channel axially extending at a distal end of the at least one viewing opening;

a second channel axially extending at a proximal end of the at least one viewing opening; and

wherein the material of the grasping insert extends within the first and second channels.

2. The surgical tool assembly according to claim 1, wherein the at least one viewing opening further comprises a lower surface defined by the at least one viewing opening, wherein at least a portion of the inclined surface of the material retainer generally extend about the lower surface.

3. The surgical tool assembly according to claim 2, wherein the at least one viewing opening comprises first and second viewing openings, the first viewing opening being provided in one of the opposing jaws and the second viewing opening being provided in the other of the opposing jaws.

4. The surgical tool assembly according to claim 1, wherein the at least one viewing opening comprises first and second viewing openings, the first viewing opening being provided in one of the opposing jaws and the second viewing opening being provided in the other of the opposing jaws.

5. The surgical tool assembly according to claim 1, wherein the material retainer is a first material retainer, the surgical tool assembly further comprising a second material retainer provided at a distal end of the opposing jaw in which the at least one viewing opening is provided, the second material retainer comprising a generally curved arcuate surface and a sloped surface extending from the arcuate surface towards a lower surface of the opposing jaw in which the at least one viewing opening is provided, the material of the grasping insert covering the sloped surface of the second material retainer.

6. The surgical tool assembly according to claim 1, wherein the inclined surface is roughened.

7. The surgical tool assembly according to claim 1, wherein an inner circumferential surface of the at least one viewing opening is roughened.

8. The surgical tool assembly according to claim 1, wherein corresponding surfaces of the first and second channels are roughened.

9. The surgical tool assembly according to claim 1 wherein a lower surface of the grasping insert comprises a plurality of teeth.

10. The surgical tool assembly according to claim 1, wherein the first channel has a first end, a second end, and a bottom surface, the bottom surface of the first channel being inclined and extending between the first and second ends of the first channel such that a depth of the first channel increases towards the first end of the first channel.

11. The surgical tool assembly according to claim 10, wherein the second channel has a first end, a second end, and a bottom surface, the bottom surface of the second channel being inclined and extending between the first and second ends of the second channel such that a depth of the second channel increases towards the second end of the second channel.

12. The surgical tool assembly according to claim 1, wherein the second channel has a first end, a second end, and a bottom surface, the bottom surface of the second channel being inclined and extending between the first and second ends of the second channel such that a depth of the second channel increases towards the second end of the second channel.

13. A surgical tool assembly comprising:

a pair of opposing jaws pivotally connected to each other;

at least one viewing opening provided in at least one of the opposing jaws, the at least one viewing opening extending through an upper to a lower surface of the opposing jaw in which the viewing opening is provided, the at least one viewing opening having a material retainer provided at the lower surface of the opposing jaw in which the at least one viewing opening is provided, the material retainer comprising an inclined surface inclined towards the at least one viewing opening;

a first channel recessed upwardly from the lower surface of the opposing jaw in which the at least one viewing opening is provided and provided at a front end of the at least one viewing opening;

a second channel recessed upwardly from the lower surface of the opposing jaw in which the at least one viewing opening is provided and provided at a rear end of the at least one viewing opening;

an elastomeric grasping insert molded onto the lower surface of the opposing jaw in which the viewing opening is provided; and

the at least one viewing opening, the first channel, and the second channel defining a continuous path, and a material of the grasping insert extending within the continuous path.

14. The surgical tool assembly according to claim 13, the at least one viewing opening comprising first and second viewing openings, the first viewing opening being provided in one of the opposing jaws and the second viewing opening being provided in the other of the opposing jaws.

15. The surgical tool assembly according to claim 13, wherein the at least one viewing opening further comprises a lower surface defined by the at least one viewing, and wherein the inclined surface generally extends about the lower opening.

16. The surgical tool assembly according to claim 13, wherein the first channel has a first end, a second end, and a bottom surface, the bottom surface of the first channel being sloped and extending between the first and second ends of the first channel such that a depth of the first channel increases towards the first end of the first channel.

17. A surgical tool assembly comprising:
