Abstract

An applicator for applying a hemostatic agent for use in achieving hemostasis in surgery comprises an absorbent material which has an attached removal string and radiopaque localizer, and a mass of hemostatic agent interengaged with the material on at least one side. In the disclosed embodiment, the applicator is used by applying the material and hemostatic agent against an open, broken, bone surface, which is oozing blood. The hemostatic agent on the material is forced into the porous, bleeding bone to stop the bleeding, and the material is then removed and discarded. Hemostatic agents applied in this manner allow hemostasis of various oozing tissues.

Claims

1. A method of achieving hemostasis of bone surfaces during surgery, comprising

a) integrally attaching a dry flexible absorbent member to a solid mass of bone was remote from said bone surface, said mass projecting from a surface of said absorbent member;

b) applying said bone wax to an open bone surface;

c) manipulating said flexible absorbent member to press said bone wax into the open bone surface to cover said surface; and

d) removing said flexible absorbent member from the situs of the bone while laving a quantity of the bone wax in contact with said surface.

2. The method of claim 1, further comprising wetting said absorbent member and mass of bone wax with liquid prior to step b).

3. A method of making a hemostatic agent applicator for surgery, comprising the steps of:

a) selecting a dry absorbent material having interstitial spaces and at least one surface;

b) applying a hemostatic agent in fluid form to a point below the surface of said material remote from oozing tissue;

c) allowing the fluid hemostatic agent to interengate the insterstices of said material and project from around the said surface outwardly;

d) allowing the hemostatic agent to solidify, wherein the step of applying a hemostatic agent comprises applying bone wax.

4. A method of making a bone wax applicator for surgery, comprising the steps of:

a) selecting an absorbent material having interstitial spaces and at least one surface;

b) applying bone wax to said absorbent material remote from an operating situs under pressure sufficient to soften the bone wax and force said bone wax into interengagement with the interstices of the absorbent material, said material projecting outwardly from around the said surface.

5. The method of claim 4, wherein the step of selecting an absorbent material comprises selecting a fibrous cotton sponge.
