NEEDLE-HOLDER.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed October 12, 1905. $erial No. 2823376.

To a whom, it may concern:

Be it known that I, LUTHER O. McNEAL, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Needle-Holders and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of the specification, and to the reference-numerals marked thereon.

My present invention relates to surgical needle holders or forceps and it has for its object to provide an instrument adapted to securely hold-needles of various shapes and sizes in which the cooperating supporting or engaging members may be made small in size and are so operated relatively to each other that a needle may be employed in a deep wound or incision and easily grasped or disengaged therein.

My invention has for its further object to provide an improved means of detachably connecting the clamping members of the holder whereby a relatively large opening and closing movement may be obtained between their clamping ends and great force exerted to grasp a needle with but a minimum lateral movement of the members.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a side elevation of a needle holder constructed in accordance with my invention, the parts being shown in open position. Fig. 2 is a similar view showing the parts in the operative position. Fig. 3 is a side elevation of the needle holder, shown partly in section, illustrating the position of the arms when the parts are being assembled or disengaged. Fig. 4 is an enlarged sectional view on the line ac9c of Fig. 3. Fig. 5 is an enlarged sectional view on the line yyof Fig. 2. Fig. 6 is a detail plan View of the clamping members. Fig. 7 is a longitudinal sectional view on line z2 of Fig. 6. Fig. 8 is a view similar to Fig. 7 illustrating the operation of the clamping members up on the curved needle triangular in cross section.

Similar reference numerals in the several figures indicate similar parts.

The needle holder embodying my inven tion comprises two clamping members or arms having cooperating clamping surfaces or shoulders which are movable relatively longitudinally when the handle portions of the arms are operated toward or from each other. One of the members or arms, indicated by 1, is provided at its forward end with anoffset portion 2 having ahead 3, the inner edge of which forms a clampingshoulder 4. The adjacent side of theportion 2 forms aneedle supporting surface 5. Theoffset 2 is also provided with acylindrical aperture 6. The other clamping member or arm, indicated by 7, has its forwardly extendingend 8 rounded to fit within and be guided by the sides of theaperture 6 so that the surface orshoulder 9 is held in operative position in front of thesurface 4 and may cooperate therewith to clamp a needle. Theoffset portion 2 is also provided with aslot 10, connected to theaperture 6, in which travels aweb 15 on theend 8 of the otherclamping member. This web projecting beneath the needle supporting surfaces serves to strengthen the operating end of the arm 7 enabling the members to be fitted together loosely and needles having a small diameter to be clamped as securely as larger ones.

Many surgical needles are made triangular in cross section while others are triangular only at one end but as the method of stitching requires the operator to release the needle after it has been inserted and withdraw it, by grasping its projecting forward end, I have provided a smallangular notch 9 in theface 9, which. is above theneedle supporting surface 5 and is adapted to engage the edge of such a needle, as shown in Fig. 8.

Theclamping surface 4 extends outwardly from thesurface 5 at approximately a right angle at its lateral edges, indicated by 16 in Fig. 6, and its intermediate or central portion is rounded or curved outwardly forming anoverhanging lip 17. The lower edge of the clamping surface, adjacent the needle supporting surface, is straight permitting either a straight needle or one formed upon a curve of either a long or short radius to be firmly clamped thereon when engaged by the shoulder orsurface 9 on the other member. It will be seen that by making theclamping surface 4 broader than the cooperatingsur face 9 that a curved needle will be supported by the vertically extendingedges 16 and prevented from being either tilted on the holder or broken by the pressure of the clamping surfaces. Thecentralportion orlip 17 of the clamping surface projecting above the needle serves to seat the latter on the supportingsurface 5 and also prevent it from being wrenched or twisted from between the clamping surfaces.

In order to cause a relatively longitudinal movement of the clamping surfaces, through a distance great enough to permit the device to receive needles of various sizes, and with a minimum movement of the rear ends or handles 1 and 7 of thearms 1 and 7 respec tively, I employ a toggle connection between them comprising thelink 19. The latter is provided at each end with laterally extending pivot pins 20-25 j ournaled in apertures or perforations formed in the arms or in lugs orbosses 26 and 27 preferably arranged upon their inner sides. Each of the lugs is divided centrally into two halves or sections by a longitudinally extending slot, as indicated by dotted lines in Figs. 1, 2 and 3, and to facilitate the removal and insertion of the link the material at one side of one of the half sections of each of the bosses is cut away to form an open bearing. This provides each arm with alocking projection 28 which overlaps the side of the link, to prevent its removal, as shown in Figs. 1 and 2, andportions 29 which receive the thrust of the journal pins. The toggle connection between the arms enables their operating ends to be disengaged as shown in Fig. 3, when the parts may be further separated by moving the link laterally todisengage it from the arms. Extending rearwardly from the link is aspring finger 30 the end of which cooperates with the arm 7 and normally exerts a tendency to rotate the link in the direction to separate the handles. The end of the spring is provided with an elongated slot oraperture 31 into which extends ahook projection 32 which cooperates with the end of the slot to limit the movement ofthe link, as shown in Fig. 1, and normally prevents the disengagement of the parts of the holder. At their rear ends the handles are provided with the usual or any preferred form of interlocking retaining devices for securing them in operative position, which in the present instance comprises a plurality ofratchet teeth 33 on one handle with which engages the edge of alip 34 on the other. handle, as shown in Fig. 2.

In assembling a needle holder thelink 19 is first secured to one of the arms by inserting one of thepins 20 or 25' in therespective bosses 26 and 27 and it is then attached in a similar manner to the other arm. The parts are then in the position shown in Fig. 3 and by a relative tilting movement of the forward end of the arms theportion 8 may be brought into alinement with theaperture 6 and inserted therein by a relative longitudinal movement of the arms which cause the link to lie in the position shown in Fig. 1 when the end of thespring 30 may be readily engaged with thehook 32.

The means of clamping a needle which I employ comprising two relatively longitudinally movable members enables the forward ends of the arms to be made comparatively small in size and as there is no increase in the space occupied by them, when opened to release a needle, the holder may be employed in stitching deep wounds without materially interfering with the operators view of the needle. By employing a toggle connection between the arms a wide range of movement between the clamping members may be obtained and a great force exerted to clamp a needle between them with only a slight relative movement of the handles laterally of each other. Further, the link and the arrangement of its bearings, as I have shown and described them, provides a simple means of uniting the parts and locking them. in operative engagement which also facilitates their disengagement when it is desired to cleanse or asepticize the instrument.
