w w NAUTH INCISION OPENER Filed July 6 1925 Patented Sept. 28, 1926.

INCISION OPENER.

Application filed July 6,

The present invention relates to a clamp or forceps to fasten. a towel over the edge of an incision during an operation to insure a covering of the skin and protect the incision and its contents from contamination.

The clamp or forceps ordinarily used for this purpose consists of pivotally connected members having aw and handle ends with ratchet means intermediate the handles operative to hold the jaws in a desired degree of compression to grip the skin and towel. With this construction the handles move in the same plane as the jaws, so that it is impossible to grip the edge of the incision without the instrument lying parallel to and close to the edge of the incision, or having the handles stand at right angles to the plane of the body, thus interfering with the operators work. 7

Among the objects of the present inven tion is to provide a construction which 1n use will lie at right angles to the edge of the incision and with the entire instrument, including the handles, lying in the plane of the body of the patient, so as not to interfere with the operator.

A further object of my invention is to provide a construction in which the towel will be turned under the edge of the incision and smoothly held insuch covering position.

' Another object is to provide a construc-' tion in which the parts can be very easily taken apart for the purpose of cleaning and sterilizing. p

The above and other advantages of the invention will be apparent from the accompanying specification and the following drawings, wherein Figure 1, is a view in isometric perspective of a device made in accordancewith the present invention, the'h'and of an operator being indicated in dotted lines.

' Figure2, is a view in bottom elevation of the device illustrated in Figure 1.

Figure 3, is a view also in bottom elevation of one of the clamp members of the device. V

Figure 4, is a view in side elevation of a spring stop and locking lug; and 7 Figures '5 and 6, are sectional views through a portion of flesh having an incision therein showing 'a method by which the device is used to grasp an edge of an incision.

Referring to the drawings in detail. the device comprises four principal elements as follows: a denticulated clamp member A, a

1925. serial No. 41,572.

pointed lower clamp member B, a spring stop and locking member C, and a sliding clasp D. The structure of the upper clamp member A, as clearly shown in Figure 3, comprises a downwardly and inwardly curved outer end 1 having teeth 2 therein, the edges of the teeth being ground to somewhat less than a cutting edge. A cut-away portion 3 is provided in each side of the upper clamp member to permit the removal therethrough of the sliding clasp D, This structure permits the device to be readilv assembled or taken down for cleaning.- ittached to one side of the upper clamp member A is a rearwardly extending spring The spring at is provided with a hooked outer end 5 to engage a ratchet 6 in the side of the inner clampmember B to hold the parts in a required degree of compression. in aperture 7 in the upper clamp member A permits the insertion therein of a locking lug to he later described.

The lower clamp member B is constructed of a flat piece of metal, the inner end thereof being curved downward and outward and being brought to a point 8, a transverse stop member 9 being provided rearwardlv of the point to limit the penetration of the point. One side of the lower clamp member B is notched to form a ratchet 6 with which the hooked outer end of the spring 4: enga e The lower clamp member is provided with a longitudinal slot 10 in which alocking lug .11, carried by the spring stop member C is slidably mounted. The spring stop member is'a flat sheet of spring steel having the end 12 thereof upturned to form a stop for the slidable clasp D. Thelocking lug 11 is integrally connected to the lower face of the spring stop member C and is provided with a rounded upper portion and a flattened lower portion. The lower portion of the locking lug is of a width to be insertable in the slot 10 in the'innerclamp member B, when the spring stop member C is turned to lie at right angles with the clamp members A and B, the rounded upper portion of the locking lug 11 on the spring stop member C being of a sue to be insertable in the opening '4' in the upper clamp member. A small stud 13 on the lower face of the spring stop member C seats in a ClGPIGSSlOH, not shown, in

the top of upper clamp memberA to hold member C in position thereon. The slidable clasp D is of a sue to receive the upper and lower clamp members in the manner shown in Figures 1 and 2. The inner end It of the upper clamp member A is upturned to serve a stop to limit the movement oi? theslidaole clasp D (lining a compressive operation of the device, while the upturned end 12st the spring stop member C serves to limit the inoveir of the sliding clasp D during a separa e operation of the device.

It will be noted that the sliding clasp D encloses the spring 1' carried by upper clamp nlier A. Therefore, when the sliding clasp D is moved inwardly along the spring extension during a separative movement of the device. the spring extension is thereby released from engagen'ient with the ratchet. During a compressive operation ol the device, the slidable clasp D is moved outwardly toward the thumb of the operator until it comes in engagement with the stop l-l formed by the upturned end of upper clamp member A. This forces the hooked outer end of spring 1 into engagement with the ratchet G on the lower clamp member B. The parts may be then drawn to a required degree of compression, the spring 4: moving from tooth to tooth along the ratchet to hold the clamp members in any desired degree of compression.

To take the device apart, as for cleaning. the outer end of the leaf spring C is raised to release the small stud 13 from engagement with the depression in upper clamp member A. The spring stop member C is then turned with the locking lug 11 as a pivot to lie at right angles to the clamp n abers. This brings the flattened lower POlLlOIl of the locking lug 11 into register with the longitudinal slot 10 in the inner clamp member. The locking lug may then be withdrawn. The sliding clasp D is then moved along the upper clamp member until the inward extensions of the clasp D are in register with the depressions 3 in the sides of upper clamp member A. The upper clamp member A may then be removed leaving the sliding clasp on the inner clamp member B. The sliding clasp D may be removed from the inner clamp member B by removing the ring 15 which is threadedly connected to the end of the inner clamp member B. This permits the sliding clasp to be withdrawn from the inner clamp member. To assemble the parts the process is reversed.

The method of use of the device is shown in Figures 5 and 6, wherein an incision 16 through the skin of the patient is indicated. A linen towel or napkin 17 is first laid over the incision, as shown in Figure 5, and the clamping device is positioned with the pointed end of the lower clamp member adjacent an edge of the incision, sufiicient downward pressure being exerted to bring the point 8 of the lower clamp member below the edge of the incision and the toothed end of the ill upper clamp member inside the incision and below the upper edge thereof. The parts are then drawn to a compressed position, as shown in Figure 6, causing the toothed end of the upper clamp member to roll the towel underneath the skin. As the parts are drawn together the point 8 penetrates the skin for its full length until stopped by the cross member 9. It will be noticed in Figure 1, especially, that the point 8 curves upwardly above the line of the teeth 2 so that when the parts are drawn to the closed position as shown in Figure 6, the point 3 is slightly above the plane of the ends oi the teeth 2, causing the towel to be rolled under the edge oi the incision. This rolling or the towel under the edge of the incision holds the towel closely to the edge of the incision between clamps, preventing the towel "from looping up between the chimps, as t'n ,lIQllllf. happens when the edge of the towel lies flat upon the edge of the incision, thereby permitting exposure of the edge 01 the incision. The towel or napkin is then folded back over the outer end of the clamp and back over the entire instrument, with the instrument itself extending outwardly from the incision and lying upon the body of the patient at right angles to the edge of the incision. shown by the drawings the handle and all the operative parts of the device will lie [hit upon the body of the patient, insuring the minimum of interference with the operator. The straight line operation of the parts. as indicated in Figure 1, it will be evident. greatly increases the ease of manipulation of the device.
