COMBINATION HENosTAT AND INTRAVENoUs NEEDLE Feb. 6, 1962 Filed July l5, 19650 INVENTon ROBERT J. M\L.|TANA 3,019,790 1 COMBINATION HEMGSTAT AND INTRAVENODS NEEDLE Robert J. Militaria, 87 NE. 88th St., Miami, Fla. Filed July 15, 1960, Ser. No. 43,184 4 Claims. (Cl. 12S-322) This invention relates generally to surgical instruments and is more particularly directed to such an instrument which automatically positions an intravenous needle in a vein or artery.

In general this invention consists of a scissor type clamp such as a hemostat upon which is mounted a holder for a hypodermic needle, which holder operates in unison with the hemostat so that when the jaws of the hemostat have engaged the walls of the vein to block on" the ow of blood therethrough, the hypodermic needle is simultaneously and automatically thrust forwardly into the vein to permit the ilow of intravenous therein. When the hemostat is manipulated to release the vein of the jaws of the hemostat the hypodermic needle is quickly and gently withdrawn from its position in the vein.

Therefore it is a principal object of the present invention to provide a surgical instrument which permits a hypodermie or intravenous needle to be easily and properly inserted into a vein, artery and the` like.

Another object of the present invention is to provide a scissor-type clamp such as a hemostat with a toggle joint support for an intravenous needle operatively connected thereto, whereby upon the clamping of a vein or artery, the support thrusts the needle forwardly into the vein or artery beyond the position at which the vein is clamped by the instrument.

Another object of the present invention is to provide a scissor-type clamp such as a hemostat with a holder for an intravenous needle mounted thereon whereby Vthe device need not be surgically sterile since the manner of receiving the intravenous needle is such that the needle which must be surgically sterile is not caused to become unsterile.

A still further object of the present invention is to provide a scissor-type surgical clamp with a holder for intravenous needles, lwhich device will receive needles of various sizes in length and cross section.

With these and other objects in view, the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modiiied so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

FIGURE 9 is a fragmentary perspective view of an intestinal clamp embodying my invention.

Referring to the drawing wherein like numerals are used to designate similar parts throughout the several views, thenumeral 10 refers generally to my surgical instrument consisting of a scissor-typey clamp commonly known as a hemostat or intravenous clamp having a pair of handle members 11 and 12 withnger receiving members 13 and 14 at one end and opposed facingjaws 15 and 16 at the other end. The handle members 11 and 12 are pivoted together adjacent theirjaws 15 and 16 by apivot pin 17, the handle member 11 being slotted as at 18 to form bifurcatedmembers 19 for receiving aleg member 20 of the handle 12 therebeteen. Secured to the top of thepivot pin 17 is asleeve 21 for receiving telescopically the body portion of ahypodermic needle 22.

Adjacent thelinger engaging members 13 and 14 at their inner portions are a pair of ropposedclamp members 24 and 25 which are adapted to' become interengaged to lock the jaws .15 and 16 in a closed position. This occurs when the handlemembers 11 and 12have been pivoted about thepivot pin 17 in the direction toward each other. Carried by the handle members 11 and 12 are a pair oftoggle arms 26 and 27 whose inner ends are pivoted together by thepivot pin 28 and their outer ends pivoted by pivot pins v29 and 30 to the handle members 11 and 12 respectively. On the top portion of thepivot pin 28, there is mounted an open endedbracket 31 provided with acap 32 pivoted at one side as at 33 for retaining therein thebase member 34 of thehypodermic needle 22. Thebase member 34 which is tapered at both its ends is prevented from sliding within thebracket 32 by the ends of the'bracket which taper likewise and engage thebase member 34 at both ends. Attached to thebase member 34 is arubber hose 35 which conducts the llow of blood, plasma, medicinal iluids, etc. fron'ra bottle to theneedle 22 and into a vein orartery 35, the latter being indicated by dotted line.

In the normal operation ofthefsurgical instrument 10, a person will take the device Itl'by lthe nger engagingmembers 13 and 14 with one hand and thehypodermic needle 22 at itsbase portion 34 to which thehose 35 had been attached, all of which had been previously of ansterilized. The operator will insert theneedle 22 through the sleeve 2l and slide it Vtherethrough until thebase member 34 can be slipped into thebracket 31 and thecap 32 swung to its closed position. Now the handle members 11 and 12 are made to swing in a direction away from each other pivoting about thepivot pin 17 to cause thejaws 15 and 16 to arrive at an open position. Simultaneously with the handle members 11 and 12 moving away from each other, thetoggle members 26 and 27 will pivot about thepivot pin 28 and swing from a sideby-side folded position to an open and almost aligned position as shown by FIGURE l. The swinging movement of thetoggle members 26 and 27 causes theneedle 15 to slide in thesleeve 21 away from ends of thejaW members 15 and 16. Now, the operator will place thejaws 15 and 16 astride the vein orartery 36 with the end of the needle in close proximity to theartery 36. Force is applied by the operators lingers on thefinger pieces 13 and 14 to cause the handle members 11 and 12 to pivot about thepivot pin 17 in a direction towards each other. This causesV thejaws 15 and 16 to come toward a closed position, whereby the side walls of the'artery 36 are engaged and squeezed together. Simultaneously therewith, theVtoggle members 26 and 27 pivoting about theirpivot pins 28, 29 and 30 will swing'toward each other and cause the inner ends of thetoggle members 26 and 27 as well asthepivot pin 28 andbracket 31 to slide in a direction toward the sleeve'21. Thebase member 31 as Well as thehypodermic needle 22 is made to slide for- Wardly to cause the free end of theneedle 22 to slide in the ,direction of theartery 36 which is now being gripped by the jaws and 16.V Thehypodermic needle 22 slides suiciently to cause the end of theneedle 22 to pierce the upper wall of theartery 36 and move inwardly thereof, a relatively short distance. Theclamps 24 and 25 now engage each other to hold the device 11B closed. The device Y1G is now vin position topermit the intravenous medicinal fluids to ow into theartery 36 while the ow of blood in the artery is stopped by the tight gripping action of thejaws 15 and 16. I, When the operator has decided to stop the intravenous flow of iiuid into theartery 36, he again grasps the finger pieces `13 and14, presses them together slightly to release theclamps 24 and 25 and then forces theiinger pieces 13 and 14 in a direction away from each other.y

This causes thejaws 15 and 16 to swing to an open position and release their hold on theartery 36. At the same time, thetoggle members 26 and 27 pivot on thepivot pins 29 and 30 to swing the inner ends of thetoggle members 26 and 27 which support thebracket 31 and the-needle basel member 34, in a direction away from thesleeve 21. This effects the withdrawal of thehypodermic needle 22 from theartery 36, the instrument 10 -now being ready to be used again after being cleaned and sterilized.

4 In order to increase the versatility 4of thesurgical instrument 10 so thathypodermic needles 22 of various sizes may be accommodated by thedevice 10, there is vshown a modified structure of theneedle receiving sleeve 21. In FIGURES 6 and 7 there is shown acradle 40 havingresilient leg portions 41 which are arcuate in shape having outwardly extendinglip portions 42 for receiving aneedle 21. The remaining structure of the hemostat -10 is identical to thatdescribed hereinabove. Instead of 'sliding `a needle within therigid sleeve 21 as must be done in theinstrument 10 previously described, the hypodermic needle d3 is laid on thelips 42, 42 and forced downwardly, 'theleg portions 41 being resilient will ex outwardly and permit theneedle 43 to slip into position. Theflexible leg portions 43 will bear slightly on the side wall of theneedle 43 yet will permit different sized diametered needles to be accommodated by and 'slide within thecradle 40 when the hemostat '10 is actuated as aforesaid.

Referring now to FIGURE 8 there is shownholder 121 for thehypodermic needle 22 in lieu of theholder 21 previously described, whichholder 121 is removable so thatholders 121 of different sizes may be used as various sizes of needles are applied to the instrument 111. The remaining structure oftheinstrument 50 is identical in construction with that of the above describedsurgical instrument 10. Theleg members 19, 2t? of thehemostat 10 are pivotally secured by apivot pin 117 whose upper end is split or bifurcated as at 120 with aperipheral shoulder 118 formed at substantially its mid-portion which in cooperation with anut 122 threaded on the end of Vthepivot pin 117 secures themembers 19 and 20 together for pivotal movement. Theneedle holder 121 is provided With asleeve portion 123 whose inner diameter permits the use of an appropriately sizedhypodermic needle 22. Depending from the lower surface of thesleeve 123 is a socket 119 which tits tightly and iirmly over the bifurcated end 126 of thepivot pin 117. The socket 119 which frictionallyengages the bifurcatedend 120 can be removed from thepin 117 upon application of an upward force on the sleeve 12.3 whereby thehypodermic needle holder 121 becomes disengaged from thepin 117. If a diiferent sizedhypodermic needle 22 is needed, aneedle holder 121 having `asleeve portion 123 that will properly `accommodate thebody portion 22 of the desired hypodermic needle is selected and forced in place on the bifurcated end 12d of thepivot pin 117.

In FIGURE 9 there is shown another adaptation of my invention to a conventional surfaceintravenous clamp 50 having handleportions 53, 54' andjaw portions 51 and 52 terminating in iiat ring portions 55, S5. The clamp 5d is provided with a pivot means as described hereinabove and ahypodermic needle holder 21 mounted thereon. In this instrument Sil any of the holders 4t?, 121 may be used in lieu of theholder 21 though the latter is shown in position in order to explain the operation of the surgical instrument 5t). In the normal use of the surfaceintravenous clamp 50, the operato-r grasps the vein to be fed intravenously by the flat rings 55 and causes the jaws -51 and 52 to come to a closed position. As is eX- plained above in `connection with theinstruments 10, the handles S3, 54 are locked together. Now the operator takes the hypodermic needle'22 and slides it through theholder 21, or whatever other holder might be used, and directs the point of theneedle 22 at the vein that is being held by the rings 55. A furtherforward movement of the needle V22 will cause the vein to be pierced and theneedle 22 to be in position to permit the ilow of intravenous uids throughthe needle and into the Vein. In thissurgical clamp 50, the piercing of the vein by theneedle 22 is not done automatically as occurs in theintravenous clamps 10 as described hereinabove. After the vein Vis, grasped by the clamp `50, Vthe operator can use thesleeve 21 for guidance in sliding the needle toward the vein.` Thesleeve 21 as welllasrthe instrument 50 operates thereafter as a holder for theneedle 22. l n What I claim as new and desire to secure by Letters Patent of the United States is: l
