ABSTRACT:
The hemostatic surgical instrument comprises a scalpel provided at its anterior end with an upwardly directed surgical blade. A unique guidance means, or plow-like structure, is connected to the anterior end of the scalpel, immediately beneath the surgical blade. The plow-like structure allows the scalpel to be positioned at an appropriate depth and location with respect to individual tissue layers during formation of an incision. The instrument further comprises a stapling device with curved edges that may be used in conjunction with the scalpel to provide for placement of rows of surgical staples on either side of an incision as the incision is formed, thereby minimizing bleeding. The stapling device preferably is composed of wheels pivotally connected with the scalpel, the wheels being rollable along the surface of the tissue and capable of sequentially ejecting staples on either side of an incision as the incision is formed by the scalpel. The curved edges of the stapling device allow the instrument to be readily used for making incisions in tissues with complex curvature, such as would be encountered with pericranial incisions.
