11 Claims.

This invention relates to improvements in needles, particularly tubular needles of the artery or vein injector type.

One of the objects of the invention is to provide a tubular needle having improved means for facilitating its insertion within an end of a flexible, collapsible tube, for example, a vein or artery.

Another object of the invention is to provide a needle having improved means for binding around the outer wall of the needle, the end of the tube into which the needle is inserted.

Another object of the invention is to provide a tubular needle in which the clamping means may be fixedly adjusted longitudinally of the needle.

Other objects of the invention will be apparent from the description and claims which follow.

United States patents, No. 1,951,436 and No. 2,084,864, to Levi Scott Paddock, disclose methods of curing meats in which curing pickle is pumped under pressure through the circulatory system of the meat. Illustrative of the present invention, the device will be exemplified for curing meats according to the methods disclosed in the aforementioned patents. However, the device is equally adaptable as a surgical instrument as well as an instrument for the professional care of the dead. Other uses of the device will be apparent also.

In the drawing, like characters of reference are used to designate similar elements.

Figure 1 is a perspective view illustrating the device constructed in accordance with the present invention.

Figure 2 is another perspective View of the device.

Figure 3 is a side view showing the clamping jaws in locked position.

Figure 4 is another side view showing the needle about to be inserted within a vein of a cut of meat.

Needle I comprises enlarged nipple shank 2, the passage of which communicates with the passage of needle shank 3. Needle shank 3 is angularly ground at its free end to facilitate its insertion within the end of a collapsed tube. Shanks 2 and 3 may be machined as a unit, or as shown in the drawing, shank 3 may be pressed fitwithin shank 2.

Member 5 is substantially H-shaped. It comprises cross member 6 provided with central opening I and corresponding side members 8. Side members 8 at one each of their corresponding ends, as at 9, are provided with angularly extended wings Ill. Member 5 is mounted through opening I on needle I. It may be rigidly affixed on needle I or, as shown in the drawing, it may be removably mounted for adjustment longitudinally of needle I, but fixed against free movement, as by set screw II.

Opposed clamping jaws I2 are pivoted, as at I3, within suitable openings provided in side pieces 8. Jaws I2 are pivoted for lateral movement from and toward the outer walls or periphery of needle I and engage needle I adjacent the free end of needle shank 3.

Jaws I2 are provided with integral arms I4 which extend rearwardly of pivot points I3. Toggle link I5 is secured intermediate arms I4 and adjacent the free ends thereof. Toggle link I5 comprises links l6 and I1 pivoted to one another at one each of their ends, as at l8, the link I6, at its opposite end, being pivoted to one of the arms I4, as at I9, and the link IT, at its opposite end, being pivoted to the other of the arms I4, as at 2i]. Obviously, one such link I5 is all that is required. However, as shown in the drawing, similar links may be employed to either side of arms I4.

Substantially T-shaped finger grip M is pivoted, as at 22, to wings It, and, as at I8, to toggle link I5. When grip 2| is depressed, as at end 23, as shown in Figures 1 and 2, toggle link I5 is centrally drawn inwardly toward member 5 and simultaneously clamping jaws I2 are caused to spread to their outermost open position relative to needle I. Concomitantly, when grip 2| is depressed, as at end 24, as shown in Figure 3, toggle link I5 is centrally moved outwardly away from member 5 and simultaneously jaws I2 are caused to close firmly against needle I.

Jaws I2 are made of relatively rigid spring steel or other suitable material, and are made to positively engage the outer Walls of needle I slightly ahead of toggle link I5 being moved to its straight line, outermost spreading position between arms It. However, it will be noted that when grip 2| is depressed at end 24, movement of toggle link I5 is continued outwardly to a point slightly beyond the straight line position between arms I4, and also that further movement of toggle link I5 is prevented by abutment of end 24 against member 5. Thus, toggle link I5 serves to firmly and positively lock jaws I2 relative to the outer walls of needle I.

'Ioo, it will be seen that when end 23 is depressed, toggle link I5 in conjunction with pivots I3, serves to equally and positively maintain jaws I2, away from the walls of needle I.

Movement of member 5, longitudinally of needle I, previously described, provides similar movement of jaws l2 and thus, readjustment of jaws [2 relative to the end of needle l, following sharpening or regrinding of the end of needle I.

Figure 4, shows the jaws l2 in open position, and needle I in the course of being inserted within the end 25 of vein 26, which previously has been dissected, by an operator not shown, out of meat cut 21. This figure shows also, flexible tube 28 firmly afiiXed, as by collar 29, to free end 30 of nipple shank 2, for the carriage of fluid to needle I.

I claim:

1. In combination with a hollow needle, clamping jaws and means including a toggle link operatively associated with the jaws and adapted for positively locking the jaws against the outer walls of the needle.

2. In combination with a hollow needle, clamp-- ing jaws and means including a toggle link operable between the jaws to positively lock the jaws against the outer Walls of the needle.

3. In combination with a hollow needle, clamping jaws provided with toggle link locking means.

4. In combination with a tubular needle, clamping jaws and a toggle link operable between the jaws to positively lock the jaws against the outer periphery of the needle.

5. In combination with a tubular needle, a pair of clamping jaws pivotally connected with the needle, each of the jaws having a rigid arm extended rearwardly of its pivot point, a toggle link connecting the pair of arms and means controlling the toggle link to open and close the jaws relative to the needle.

6. In combination with a tubular needle, a pair of clamping jaws pivotally connected with the needle, each of the jaws having a rigid arm extended rearwardly of its pivot point, a toggle link connecting the pair of arms and means controlling the toggle link to open and close the jaws relative to the needle and to positively lock the jaws substantially against the outer periphery of the needle.

'7. In combination with a tubular needle, a pair of clamping jaws pivotally connected with the needle, each of the jaws having an integral arm extended rearwardly of its pivot point, a separate link pivotally connected with each of the arms and with each other and means controlling the links to open and close the jaws relative to the needle and to positively lock the jaws substantially against the outer periphery of the needle.

8. In combination with a tubular needle, a member removably aiifixed on the needle for longitudinal adjustment and providing a pair of lateral pivot points equally spaced from the needle, a clamping jaw pivotally connected with the member at each of the pivot points, each of the jaws having an integral arm extended rearwardly of its pivot point, a toggle link connecting the arms and means functionally engaging the member and toggle link and operable to control the toggle link to open and close the jaws relative to the needle and to positively lock the jaws substantially against the outer periphery of the needle.

9. In combination with a tubular needle, pivoted clamping jaws provided with integral rearwardly extending arms, a toggle link spreadable between the arms to close the jaws relative to the needle, and means operable to move and to hold the toggle link slightly past its straight line position to positively lock the jaws substantially against the outer wall of the needle.

10. In combination with a tubular needle, pivoted clamping jaws provided with integral rearwardly extending arms, a toggle link spreadable between the arms to close the jaws relative to the needle, and means operable to move and to hold the toggle link slightly past its straight line position to positively lock the jaws substantially against the outer wall of the needle, the needle at its free end being beveled to facilitate its insertion into the end of a tube.

11. In a tubular needle including clamping jaws movable laterally relative to the outer wall of the needle, said jaws being mounted upon means removably affixed for longitudinal adjustment longitudinally on the handle.
