Gelatin sponge (gelfoam®) has proved to be effective in controlling the bleeding from punch biopsy wells, but its application is sometimes clumsy and time consuming. When introducing the gelatin sponge into a biopsy well by the use of tissue forceps, the sponge is often pulled out as the forceps is withdrawn. Usually, when this happens a new sponge must be inserted, because the first sponge has become so saturated with blood that it no longer will pack sufficiently to accomplish hemostasis. In the meantime, the bleeding has continued, especially if the biopsy site happens to be a vascular one. The use of a glass injector, as shown in the accompanying photograph, permits the operator to apply the sponge directly into the well without loss of too much time or motion.
In the preparation for the taking of a biopsy specimen, the injector is sterilized by boiling and allowed to
