SURGI CAL APPARATUS Filed Feb. 10. 1950 2 Sheets-Sheet 2 INVENTOR.

E. E. YUUNBREN Patented Aug. 2, 1932 UNITED STATES EARL E. YOUNGREN, OF SAN FRANCISCO, CALIFORNIA SURGICAL APPARATUS Application filed February 10, 1930. Serial No. 427,331

This invention relates to improvements in surgical apparatus and hasparticular ref erence to a device for use in the setting of broken bones.

The principal object is to produce a device wherein the ends of a broken hone may be accurately brought into alignment with each other and then held in this adjusted potion until the fracture has entirely knit together.

Another object is to produce a device of this character which is readily adjustable. and one wherein the parts may be quickly manipulated in accordance with the wishes of the user.

A further object is to produce a device" which is relatively strong and one which will not be easily deranged when placed.

A still further object is to produce a device which is economical to manufacture and one which may .be easily cleaned so that a sanitary condition would exist.

Other objects and advantages will be apparent during the course of the following description. 1

In the accompanying drawings formin a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure I is a top plan view of my device as the same would appear in use on a broken bone,

Figure II is a side elevation of Figure I,

Figure III is a fragmentary detail perspective view on an enlarged scale of one of the center needle holders,

Figure IV is a cross sectional view on an enlarged scale taken on the line 4-4:, and

Figure V is a similar perspective View showing one of the end needle holder clamps.

In the setting of fractured bones itoften occurs that the bone is broken diagonally and as a consequence the pulling of the ligaments causes the broken ends of the bones to slip past each other even after the fracture has been set and as a result many shortened limbs occur or other-deformities and as a consequence it is sometimes necessary to rebreak the fracture and reset the same. In some instances it is necessary to hang a weight so that a pull is constantly maintained in a direction to counteract the pull ing of the ligaments. This pulling is exceedingly hard on the patients and neces'si tates lying in a fixed position for a long 55 time.

Applicant has therefore devised a device wherein a series of needles are extended through the bone, one needle on each side of the fracture and one needle spaced a short as distance away from each side of the fracture and by connecting these needles with suit-- able clamping device and through the medium of certain adjustments the ends of the fractured bone may be caused to move into alignment with each other and after being secured against further movement will be held in this position until the device is repioved after the fracture has completely nit.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the letters A and B refer to the two halves of a broken bone, the fracture being shown at C. In order to accomplish my purpose I bore through the bone, spaced holes which accommodate needles 5, 6, 7 and 8. The needles 6 and 7 will hereafter be termed the center needles and the needles 5 and 8 will be hereafter termed the end needles. The end needles 5 and '8 are moved to and away from each other through the medium of turnbuckle arrangements spaced on opposite sides of the bone. As these turn-buckle arrange- 8t ments are identical but one will be described.

Referring to Figures I and II the numeral 9 refers to a tubular element, interiorly threaded so as to accommodate threaded offset arms 11 and 1:2. These arms 11 and 12 each have pivoted to their free ends, a needle clamp as shown at 13 and 14 respectively These clamps each carry a set screw shown at 16 and 17 respectively, which engage the end of? the needle as it passesthrough an opening 18, (see Figure V) formed through the clamp. By th's arrangement when a turning tool is inserted in the opening 19 in the tubular element it will be readily understood that by rotating the tubular element the needles 5 and 8 will be moved toward or away from each other depending upon the direction of rotation of the tubular element. This will serve to bring the ends of'the fracture toward or away from each other so as to get the proper end to end relation.

In order to keep the ends of the bone from pivoting upon the needles 5 and 8 and thus dropping out of alignment, I provide clamps for the needles 6 and 7 which clamps consist of blocks 21 slidable upon the tubular element 9 and provided with vertically adjustable center needle holders having a threaded shank 22 which passes through the block 21 and has wing nuts 23 and 24 screwed thereon for the purpose of adjusting the vertical movement of the needle holder with relation to the blocks 21. This center needle holder carries a set screw 26 wh ch engages the end of the needle thus locking the needle in an adjusting position.

It will thus be seen that by the proper adjusting of the center needle holders and by manipulating the wing nuts 23 and 24 the ends of the bone may be adjusted so that their horizontal alignment is correct. It will thus be seen that by this arrangement I have produced a device which will not only hold the ends of the bone spaced from each other the proper distance and one which will elimi nate the use of weight to accomplish this object also one which will permit certain movement of the body without movement taking place in the fracture and one which will permit the ends of the bone to be brought into axial alignment as well. It is obvious that a certain amount of horizontal movement of the ends of the bone may be accom- 'plished by lengthening the turn-buckles on Having thus described my invention, I

claim:

1. In a device of the character described, comprising a pair of needles adapted to be passed through a fractured bone at a point adjacent the fracture, a second pair of needles adapted to be positioned through a bone at a point remote from said first mentioned needles, pivoted needle clamps secured tosaid second mentioned needles, ofiset arms pivotally secured to said clamps, turn-buckles adjustably connected with the offset arms,

blocks laterally movable on said turnbuckles, vertically adjustable needle holders positioned in said blocks and adapted to engage said first mentioned needles for the purpose specified.

2. In a device of the character described comprising a pair of needles adapted to be positioned thru a fractured bone at a point adjacent the fracture, a second set of needles adapted to be positioned thru the bone at a point rem te from said first mentioned needles, pivoted clamps for retaining the second set of needles, off-set arms pivoted to said clamps and turnbuckles adjustably secured to said offset arms whereby the actuation of said turn buckles will move the fractured ends of said bone, blocks slidable on said turn buckles, vert cally adjustable needle holders carried by said blocks and engaging said first mentioned needles whereby adjustment of said needle holders will cause the ends of said bone to be brought into axial alignment.

In testimony whereof I aflix my signature.

EARL E. YOUNGREN.
