commonly seen and instrument made up of hinged levers with apwith this type' of instrument needle in such responding to the skillful Patented Nov. 21, 1944 UNITED STATES PATENT OFFICE SURGICAL HOLDER William 0. Jones, Baltimore, Md. 'Application'Mam'olr 2, 1943, Serial No. 477,742

The present invention relates to that category or classification of hospital supplies and accessories embodying forceps and equivalent holdforceps and siriiilar holding tools on the market and in useby surgeons. However, the one most perhaps most used is an propriate grips and retaining devices, the same having curvatsuperunposed jaws whose inner surfaces" are formed with teeth or otherwise roughened to grasp the hight portion of the suture needle 'therebetween. But the difiiculty and many others in use is that the needle has to be grasped so tightly as to cause it to fra'c'ture and break, or where it is not sufilciently gripped, it rocks bodily backand forth and gets out of position only to delay expert and skilful handling by the user.

My aim is, therefore, to generally improve upon surgical-needle holders of types known to* me and in fact to provide what is believed to be a somewhat different style and form which overcomes. the aforementioned objection and which" is outstanding in that it will positively hold the position as to expedite and facilitatemanipulation thereof.

Another feature and advantage is predicated on the provision of a construction in which the parts are separable, whereby to provide for precision manufacturing but particularly to permit repair and replacement and frequent cleaning to render the same always in a reliable aseptic condition.

More specifically, the preferred embodiment of the invention is characterized by a body in which a spring-pressed retention rod or pin is slidably -mounted, the pin coasting atits worl -engagimg end with a hook-like keeper or adapter, there Being levers pivoted on the body and the meet- :ing. means between the levers and retention pin to promote a refined and delicate coaction susceptible or expedient operation, whereby to permit the levers to be manipulated readily while hands of the surgeon.

@tho'r features and advantages will become morerreadily apparent from' the followingdescription and .the accompanying illustrative drawings.

Figure 9 is a view similar to Figure 3 show- :ing'a: modified form or style of the invention.

Figure 10 is a view of the sleeve iike sheath and its associated plunger-like retaining pin or rod, this being the style shown" in Figure 9.

In carrying into'practice the ideas of the instant invention I found it expedient and practicable to adopt two difieren-t styles or forms wherein movement of the levers in a direction toward each other serves to exert an outward thrust upon the needle clamping or retaining pin, there being" a similar arrangement in which thereverse is true. In the latter, the pivoted lovers acttd move the pinin a direction toward the user in a marinertohe hereinafter more explicitly covered.

Attention is first invited to the form of the invention, the primary form, which is compreat i6 (see Figure 6), the opposite end being provided with a beveled notch I1 and an adapter hook or keeper 18. These features I! and 18 P ovide an ideal seat for the curved bight D01- .tion of the conventional surgical needle l9 as is obvious from the drawings. The flanged end l6 of the sheath rests against the threaded end of the guide socket l2 where a knurled swivelled nut 20 serves to join and assemble the parts as brought out to advantage in Figure 3. The plunger-like unit comprises a rod or pin 2| (see Figure 8) which is mounted for reciprocation in the bore of the adapter sheath Hi. The Outer end thereof projects into the beveled seat region l1 and the extremity presses into the crotch 22 whereby to properly engage the needle. The opposite end of the slide-pin is threaded as at 23 to accommodate the fitting 24. This comprises a block-like part having curvate surfaces 25 functionin as cams. In addition it has a socketed extension 26 receiving the threaded portion 23 and joining the two parts 2! and 24 together to function as illustrated.

The handles or levers 21 and 28 are duplicates and the corresponding inner ends are hingedly or pivotally mounted as at 23 between the furcations l4. Adjacent the pivots 29 are specially formed portions 30 which function as thrusting cams and engage the cam surfaces 25. There is a spring 3| in the socket of the part 12, this spring surrounding the pin or rod 2| and bearing against the shoulder provided by the tubular extension on the fitting 24. The spring is normally expansible in a longitudinal direction to disengage the clampin end of the pin 2i from the hook I8 and crotch 22. In practice, the outer ends of the handles are provided with ringlike finger grips 32 and 33 having the usual coacting resilient detents 34 and 35. These parts 34 and 35 are brought into overlapping relation and engage and hold the handles together when the needle is in use. A slight lateral movement of the handles in relation to each other serves to quickly engage or disengage the detents 34 and 35.

Referring to Figures 1 to 8, singly and collectively it is quite evident that by simply grasping and pressing the levers 21 and 23 toward each other, they swing on their pivots 29 (see Figure 3) and bring the thrust cams 33 into engagement with the coacting earns 25. This serves to press the rod 2! in a direction outward in relation to the surrounding sleeve or sheath l5. With the bight portion of the needle in the seat or crotch 22 it is evident that the rod comes into firm engagement therewith and presses it home. At the same time the detents 34 and 35 engage and hold the levers in this position during the manipulation of the needle. Now, in case the needle needs to be shifted bodily, that is. in an axial path, this can be done by loosening the knurled nut 20. Then the sheath and needle therein can be swun either to the right or left depending on the angle of manipulation or the access to the incision.

The needle can be just as easily released as gripped. That is say, by simply kicking" detents 34 and 35 apart in a well known manner, the levers swing apart and the spring 3| returns the retaining or retention pin 2| in an evident manner.

Now. while in the construction just described the bringing of the levers together forces the pin I against the anvil-like seat 22, it is sometimes advisable to slide the pin in an opposite direction, that is, in the direction toward rather than away from the user. This is brought out in the modification shown in Figures 9 and 10. The only difference here is in the outer end construction of certain parts and the inner end construction. All parts which are the same as already described will be referred to by the same numerals. That is to say, the body II has the socket-like threaded extension l2 to accommodate the knurled nut 20 which binds the flangelike end I6 in place, the flange being on the slightly different tube-like sheath l5a. In this form the levers 21a and 28a have their headed inner ends pivoted as at 29 between the furcations M. It is to be noted, however, that here the shoulders 30a differ slightly. That is to say. they are designed and constructed to engage the cam surfaces 36 of the actuator. The actuator is provided with a socket 26a to accommodate the threads 23 on the slide rod or pin 2i. In this instance, the pin is provided at its outer end with a circular head 31 or appropriate dimension engageable with the adjacent abutment or end 38 of the sleeve. This permits the bight portion of the needle to be engaged between the parts 31 and 38. Also, pushing the levers together exerts a movement against the cams 36 to slide the pin 22 in a direction toward the operator. So, in this instance, the spring 3la. exerts a stress on the shoulder 39 and surrounds the reduced portion 40. This, therefore, pushes the head 31 outwardly beyond the accommodation tube 15a. to normally disengage or separate the parts 31 and 38. In principle, however, both forms of the invention are approximately the same and the claims are. therefore. so worded.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size, and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.
