UNITED STATES PATENTS 13 Claims, Drawing Figures Kappmeier 128/1 63 Patented May 2, 1972 3,659,609
2 Sheets-Sheet 1 Patented May 2, 1972 2 Shoots-Shoot 2 HEMOSTATIC APPARATUS FOR OPERATIONS ON THE HEAD OF HUMAN BEINGS BRIEF SUMMARY OF THE INVENTION The present invention relates to hemostatic apparatus that can be used for operations on the head of human beings, and more particularly, but not exclusively, for scalp grafts.
l-lemostasia refers to a process of stopping hemorrhages, and is usually effected by applying a tourniquet on the limb in which blood circulation is to be stopped. The tourniquet consists of a band surrounding the limb for applying compression thereto. For the lips of a wound, mechanical hemostasia is effected by the use of clips or similar instruments.
However, when it is desired to remove scalp grafts from the occipital area of the head for transplantation on another denuded area of the skull, there is no convenient hemostatic apparatus, and the operation is carried out without hemostasia. This is very objectionable because of the resulting bleeding, which interferes with the action of the surgeon.
An object of the present invention is to overcome this deficiency and to provide haemostatic apparatus which can prevent blood flow through a predetermined area of a patients scalp.
The invention contemplates haemostatic apparatus for operations on the head of a human being, more particularly for scalp grafts, which includes a frame provided with means for mounting on a patients head, and including compression means on the frame forming a loop to delimit a predetermined area on the patients scalp to apply the required pressure to render it bloodless.
In a particular realization of the invention, the frame to be fixed on the patients head is a plate of a generally rectangular shape, slightly concave on the side facing the head, with an opening or window delimiting the operative field, the frame bearing a pneumatic closed circuit member to exert the necessary pressure.
According to another feature of the invention, the pneumatic member is constituted as a flexible tube having the same shape as the frame and mounted on the concave side thereof between the outer rim of the plate and the operative window.
According to another feature of the invention, the inner tube is connected to a pumping bulb coupled with a pressurecontrol manometer. It is thus possible to pressurize the inner tube at a pressure slightly higher than the patients arterial pressure, to intercept the blood circulation.
With the above hemostatic apparatus, the removal of scalp grafts and their transplantation, is greatly facilitated.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of the apparatus according to the invention;
FIG. 2 is a profile view of a patients head equipped with the apparatus;
FIG. 3 is a rear view of the patients head of FIG. 2;
FIG. 4 is a plan view of a plate of the apparatus;
FIG. 5 is a sectional view taken along line V-V of the plate shown in FIG. .4, and
FIG. 6 is a perspective view, on enlarged scale, of a part of the fixing device of the apparatus.
DETAILED DESCRIPTION Referring to the drawing, therein is shown the hemostatic apparatus which is made of a frame including a semi-rigid plate 1, of a rectangular shape but curved with respect to its two axes to conform to a generally convex area of a patients head 2. v
The plate 1 is advantageously constituted of a light aluminum base alloy having a certain elasticity in bending. The plate I has a central opening or window 3, also rectangular, and a tubular juncture 4 for connection with a flexible tube 5 terminating in a pumping bulb 6 and a manometer 7, both similar to those employed in customary sphygmomanometers for measuring blood pressure. A strap 8 serves for mounting the frame on the pateints head and the strap is fastened to hinge pins 9 and 10 on each side of the plate 1. A supple headband 1 l is joined to the strap 8 to protect the areas of the head encircled by the strap 8.
The plate 1, on its concave side facing the head, supports a flexible tube 12 (FIG. 5)'forming a rectangular loop between the rim of plate 1 and the window 3. The flexible tube 12 communicates with the tubular juncture 4 and, consequently, with the pumping bulb 6 and the manometer 7.
The fixingstrap is also of a semi-rigid material, it comprises two ribs 8a and 8b. Rib 8a is shorter than the rib 8b and bears at its free end a screw-jack l3 intended to receive the free end of rib 8b which bears notches l4 meshing with the jacks screw 13.
When removing scalp grafts for transplantation, the above described apparatus is placed on the occipital area as represented in FIGS. 2 and 3, and the strap 8 surrounding the forehead is tightly adjusted against the latter by means of the screw-jack 13.
Once the apparatus is adjusted in place, the inner tube 12 is pumped by means of bulb 6 to a pressure slightly higher than the blood pressure, as controlled by the manometer 7. Then the skin appearing in the interval circumscribed by the window 3 and which represents the operating field is bloodless and it is possible to operate with substantially no bleeding, which greatly facilitates the operation.
It is quite evident that the invention is not limited to the embodiment described nor to its particular application to scalp grafts. As a matter of fact, the apparatus can be used for other operations on the head of a human being necessitating a localized hemostasia.
