-ing and wrapping hand tool devices.
Patented Dec. 7, 1948 "um-m) TESQPAT This invention relates to line tensioning;
This invention hasyutilityywhen incorporated in a pivoted member pair structure, especially adapted" to clamp engage ,awire, upon opposite sides of an intermediate portion tobe actedupon. This intermediate portionmay bea loop, say as a wrap about a bone fracture, in surgical, use. The wire portions as extending from the initial wrap, are clamped independently, one in each of the two relatively movable or spreadable jaw portions. The jaws may then be spread to put an opening tension on the crossed ends of the wire. With this position locked at the handle portion, the handles may then be turned to twist the wire into the more taut desired final holding position therefor.
Referring to the drawings: I Fig. 1 is a side elevation of an embodiment o the invention at assembled position for a wrap at a bone fracture;
Fig. 2 is an end elevation of one of the wire holder engaging members orjaws;
Fig. 3 is an enlarged view in side elevation of the tensioning or spread position of the wire end engaging portions as locked for the twisting stage to start; and
Fig. 4 is a fragmentary plan view of a Wire end holding clamp mounted on a wire end engaging arm of the tool.
Fractured bone sections I, 2, about marrow 3, have a line or wire 4 wrap with crossed diverging wire portions 5, 6, therefrom. The wire portion 6 enters a port I in a face 8 of a. wire engaging jaw or spread portion 9 as an arm of a member having a fulcrum at a pivotal connection I with a handle portion or grip II. Complementary to the portion 9 is a spreadportion I2 of the companion member of the tool extending past the common pivotal connection In to an additional handle portion I3, which with the portion I2 are assembled as a grip, adapted for twisting or turning in wrench-like action.
The wire end 6 as passing thru the port I passes along the outer sideof the portion'9 as away from the portion I2 as a taut straight section 14 having a bend or hump I to free end I6. Upstanding lugs or pins IT, IS, determine the sides for the bend I5 as an arc about a screw stem I9 in the member arm 9 midway between 1 mm. (011 123+ I twi The threaddirection bf thae I9, say as m de wisein Fig. 4, meansthat tensioning pull "of the section I4 toward the port I, is in theturning direction forthe stem I9 to more tightly'clamp and holdthe wire at the hump I5. The, spread arm portion ,I2, has thru its free endlport from the wire, portion 5 a straight, section 22, similar to the portion I I. The portion 22 ,extendstoa Wire clamp device 23,1similar to the devicehaving thehnurledhead 2I Likewisehere, clockwise turning of the device 23"is to efiect wire clamping, with a hump about astem 24, in its pull direction from the wire portion 5, eifecting more firm binding at the device 23.
The handle portion I3 near its free end has fixed therewith an arched spring strap 25 with its free end 26 to ride in a slideway 21 along the inner side of the handle portion II. There is thus provided yieldable means normally closing the jaws 9, I2. A pivot 29 in the handle portion I3 spaced from the hinge or pivot connection I0 away from the clamp devices 2|, 23, has rockable clearance 29 for a threaded stem 30 extending from the pivot 28 thru a slot 3I in the companion handle portion II, there to be engaged by a knurled nut 32. Setting of this nut 32 to flex the spring 25, acts to spread the jaws 9, I2, and thereby tension initially the cross reaches 5, 6, of the wire. As so locked by the nut 32, the handle pair unit II, I3, may be readily twirled in twisting the clamped-ended Wire in bending I the cross portions 5, 6, upon each other to the desired binding extent.
What is claimed and it is desired to secure by Letters Patent is:
1. For initiating and adjusting a line loop to a desired completion, a two member tool body, a pivot connection between the members for the members to provide diverging handle portions I portion remote from the connection and having the small posts or lugs I1, I9. The screw stern a bow portion therefrom to a free end having a slide connection with the adjacent side of the other handle portion and thereby to coact to spread the handle portions and cause the jaw edges to approach abutting relation, an adjusting device coacting between the handle sections to limit the effective spread action of the spring,
there being on each jawv spaced from the port,
a flat seat for a hump of a reach of the line from the loop to lodge flatwise thereagainst, and a clamp to pinch the flat portion of the hump toward the seat and thereby effecting each direction locking of the line.
2. A spread type surgical two member tool, a pivot connection between the members for the members to provideapair of opposing jaw portions one way from the connection and, the other way therefrom, a pair of diverging handle portions adapted as grasped to spread the jaw portions, each jaw having fixed therewith a line clamping seat, whereby grasping of thehandles to move them toward each other holds the line,
clamped portions taut, a handle-portion spreading spring coacting directly between the handle portions remote from the connection, and, toward.
the connection from the spring, adjusting means directly engaging the handle to limitthe spread extent of the spring and thereby determine. a held "spacing for the jaw portions, whereby the tool may be set to holdthe line tensioning for the line having opposite line portions engaged by the jaw portions.
'3. A hand tool for forming. a line loop, said tool comprising a pair of members, a. pivot connection between the members for the members to provide diverging handle. portions extending one way from the connection and jaw portions the other way from the connection, each jaw portion outer side near the connection having a pair of posts with a flat seat therebetween, and a clamp screw to press a line hump arced about the screw and within the posts to be pressed against said seat to lock the line against thrust and pull disturbance.
