Abstract

A rod-shaped device for internal use in connection with operations in body cavities and comprising a non-elastically deformable, flexible member surrounded by a soft liquid absorbing material which optionally is enclosed in an overwrap.

Claims

1. A surgical device for holding internal body parts in place during surgical operations in body cavities and which, once bent into a desired shape, will retain the desired shape, the surgical device comprising

a rod-shaped member, said rod-shaped member being composed of a soft, liquid-absorbing material,

a non-elastically deformable, flexible member embedded in said rod-shaped member, and

an overwrap means surrounding said rod-shaped member.

2. The surgical device as defined in claim 1 wherein said rod-shaped member is composed of cotton wool.

3. The surgical device as defined in claim 1 wherein said rod-shaped member is composed of plastic foam.

4. The surgical device as defined in claim 3 wherein said plastic foam is polyether foam.

5. The surgical device as defined in claim 1 wherein said non-elastically deformable, flexible member is composed of a metallic material.

6. The surgical device as defined in claim 5 wherein said metallic material is aluminum.

7. The surgical device as defined in claim 1 wherein said non-elastically deformable, flexible member is strip shaped.

8. The surgical device as defined in claim 1 wherein a perforated tube is additionally embedded in said rod-shaped member.

9. The surgical device as defined in claim 8 wherein one end of said perforated tube extends outwardly of said rod-shaped member and through an opening in said overwrap means.

10. The surgical device as defined in claim 1 wherein said overwrap means is in the form of a woven nylon tube which is closed at its ends.
