EDW'IN L. BURTON, OF MCKINNEY, TEXAS.

COMPRESS.

SPECIFICATION forming part of Letters Patent No. 575,103, dated January 12, 1897.

Application filed-December 28, 1895- Renewed November 16, 1896. Serial No. 612,386. (No model.)

- I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable Others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in surgical instruments, and more especially to that class of surgical instruments which are used for stopping the flow of blood during an amputation or other similar operation.

My invention will be understood by reference to the accompanying drawings, wherein the same parts are indicated by the same letters throughout the several views.

Figure 1 is a side elevation of my instrument, the needle being shown in full lines in the approximate position it will occupy when in use, and being shown in dotted lines as straight, which form it will assume when not in use. Fig. 2'is a top plan View of instrument as shown in Fig. 1. Fig. 3 is a detail plan view of the needle used with my instrument. Fig. t is a similar view to Fig. l of a slightly-modified form of instrument. Fig. 5 is a view similar to Fig. 3 of a slightlymodified form of needle, and Fig. 6 is adet-ail View of the gripping device for engaging and holding the end of the needle, as seen from the right in Figs. 1 and 4.

A represents the body or frame of the instrument, which is made of any suitable material, preferably of metal, and to which the needle B is pivoted, as at b. This needle is preferably made of the best steel, and is pro vided at its free end with a sharp fine point I) to enable the same to be easily inserted into the flesh of the limb or other part being operated upon by the surgeon. This needle is normally straight, and is bent upward at its point and clamped in the position shown in full lines in Figs. 1 and 4 after being inserted into the flesh, as will be hereinafter more fully described.

0 represents the device for gripping and holding the end of the needle when in use. This gripping device is attached to the end of the body or frame A by means of a screw 0 or the like passing through the opening 0 in the said gripping device. The jaws O O of coming slightly bent.

this device, provided on their inner faces with teeth or catches c, are adapted to be opened and closed by means of the arms 0 and C and thus grip the point of the needle and hold the same. The arm 0 is in the form of a segmental rack, as shown in Fig. 6, and is normally pressed away from the arm C by means of a spring 0 thus tending to hold the said arms apart and the jaws 0 open. (2 is pivotally attached to the arm 0 and incloses the end of the arm 0 and may be moved up or down thereon to release or grip the needle.

D represents a lever-arm which is pivoted at a to thebody or frame of the instrument. This lever-arm is flattened and broadened at its free end D to form a better thumb-rest for depressing the lever. The said lever is provided with an opening D therethrough, which fits over a curved arm A, provided with ratchet-teeth a on its convex side, as shown, and may be moved up and down over said arm. A thumb-catch D is pivoted, as at cl, to the lever-arm D, and is adapted to engage the ratchet-teeth a on the arm A. This thumb-catch is normally held in engagement with one of said teeth by means of the spring (1 but may be disengaged by a simple pressure of the thumb, as will be obvious.

E represents a stem which is pivoted at one end, as at (l, to the lever-arm D and works in an opening or guideway A in the frame A. The opposite end of this stem E is pivotally attached, as at d to the shoe or block F, which should preferably be covered or padded with some soft material to form a cushion, so as to prevent the bruising of the flesh when in use.

The body A is provided with an opening A to admit the finger of the operator and thus form a grip, while the thumb presses down on the plate D, hereinbefore described.

The operation of my device is as follows: The point of the needle 13, which is normally straight, as shown in dotted lines in Figs. 1 and 4, is inserted into the flesh at one side of the blood-vessel ,to be closed, and is pushed through beneath the blood-vessel until the point comes out on the opposite side. The free end of the needle is then caught between the jaws C of the gripping device 0, where it is clamped and held firmly, the needle becushioned block F is in its raised position.

A link In the meantime the The needle having been inserted and clamped, the operator then inserts a finger into the opening A of the frame A, and with his thumb presses down upon the thumb-plate D on the end of the lever-arm D. This pressure of the thumb will bear the lever-arm D downward, and the stem E, carrying the cushioned block F, will press the said cushioned block down upon the flesh above the blood-vessel, and by closing the same will prevent the flow of blood during the operation.

A guard-cap b (shown in dotted lines) may be provided to fit over the point of the needle when the instrument is in use and prevent the accidental injury of the operator. This cap should be provided with a short chain by which itis attached to the body or frame A of the instrument, as shown in Fig. 1.

My instrument may be made, either in whole or in part, of any suitable material desired, but should preferably be of metal throughout, except for the covering of the pressure-block F, which should be Chamois-leather or some similar soft material.

The frame or body of the instrument may be made eitherstraight or arched, as desired, and the size of the instrument may be varied to meet requirements.

In Fig. 5 is shown a needle having a spearpoint. I may use this form of needle, if desired, and it is preferable where a great amount of pressure is necessary to close the blood-vessel, in order that the point of the needle may be more firmly held by the gripping device.

Many modifications of my device might be made which could be used without departing from the spirit of my invention, and I therefore do not wish to limit. myself to the exact details described herein.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. I11 a surgicalinstrument of the character described, the combination with a body or frame, of a resilient needle hinged to one end of said frame; a pair of pivoted jaws mounted upon the opposite end of said frame for engaging and holding the pointed end of said needle; a block or shoe, and means mounted on said frame for depressing said block or shoe, substantially as described.

2. In a surgical instrument of the character described, the combination with a body or frame, of a resilient needle hinged to one end of said frame; a pair of toothed jaws, arms for opening and closing said jaws, and means for holding said jaws closed, mounted upon the opposite end of said frame for engaging and holding the pointed end of said needle; a block or shoe, and means mounted on said frame for depressing said block or shoe, substantially as described.
