FUNIS CLAMP Filed June 2l, 1951 I ATTORNEY Patented Aug. 17, 1954 OFFICE FUNIS CLAMP Daniel G. Jarvis, Glen Ridge, and Irvin J. Gershen, Hillside, N. J.

Application June 21, 1951, Serial No. 232,839

1 Claim. 1

This invention relates, broadly, to surgical devices, and more particularly to a device for surgical clamping purposes, which will enable the physician or surgeon to rapidly apply clamping pressure to a cord or other organ and hold the same in that position for prolonged periods of time in a manner which will become apparent as the description progresses.

A further object of the invention is to provide a clamp of the character described, wherein a pair of jaw members are provided for clamping the organ and a link is secured to one of the jaw members for reception in a nosing on the other jaw member, said link having a closure cap mounted thereon for rotation into engagement with the nosing, the nosing being provided with a recessed seat to receive the tubular neck of the closure cap.

In the drawings:

Fig. 1 is a side elevational view of a funis clamp embodying the invention, shown in its open position.

Fig. 2 is a top plan view thereof, taken on line 2-2 of Fig. 1,

Fig. 3 is a side elevational view of the clamp with the jaws shown in closed position, the link being shown in open position,

Fig. 4 is a similar view, showing the link in initially closed position,

Fig. 5 is a fragmentary elevational view, showing the link in fully closed position,

Fig. 6 is a fragmentary plan view taken on line 6--6 of Fig. 7, and

Fig. 7 is a sectional elevational View taken on line 1 -'I of Fig. 6.

In the drawings, a funis clamp IU is shown to illustrate the invention, comprising a pair of coextensive, elongated jaw members II, I2, pivotally connected together at one end, as for example, their inner ends, as by providing one of the jaw members with a bearing I3 through which a pin I4 secured to the other jaw member is passed for movement of said members II, I2,

after superposed contacting relation (Fig. 3). A link I5 is pivotally connected, as at I6, to one of the jaw members, the other jaw member being provided with a U-shaped nosing I'I at the free end thereof to receive the shank I8 of the pin I5 when the latter is rotated on its pivot I6 (Fig. 4).

A closure cap I9 is movably positioned on the link I5, as, for example, by providing said cap and link with complementary threaded portions. In the initial position of the parts shown in Fig. 1, the jaw members may be moved together and (Cl. 12S-346) into clamping relation to a cord, then upon the link I8 being rotated into the nosing I'I, the cap IS may be rotated to engagement with the nosing I'I and further rotated for tightening to precisely the degree required. The physician or surgeon using the device will soon become accustomed to the locking, clamping action above referred to so that the device may be rapidly positioned upon a cord and the link rotated into the nosing I'I and then the cap I9 may be rotated to tighten the jaw members in that position.

The closure cap I9 is preferably provided with a tubular neck 2i) and the nosing l1 of the jaw member II with a planar face 2I offset axially from the inner face of the jaw on which said nosing is formed, said planar face having a circular recess or complementary recessed seat 2| (Fig. `6) with which said neck is adapted toengage when the closure cap is threaded on the link to close the clamp, as shown in Fig. 5. In that position of the parts, it will be apparent that the link I5 cannot be rotated out of the nosing II, for the neck 2D of the cap I9, engaging the recessed seat 2| of the nosing I'I, precludes such rotation of the link in the direction indicated by the arrow in Fig. 5.

The outer faces of the jaw members are preferably parallel longitudinally as indicated at 22, 23 of Fig. 3, so as to facilitate handling of the device. The inner faces of the jaw members are provided with serrations 25, 26 of triangular outline and of uniform transverse cross-section which mesh on closing, as shown in Fig. 3, so as to effectively clamp the cord or other organ positioned therebetween.

It will be apparent that the device may be secured to the organ and the closure cap rapidly rotated to clamp the jaw members on the organ. The physician using the device will soon become adept at it so that he will be able to apply and remove it with dexterity and rapidly. The cap I9 may be only partially threaded to the position at which the same is fully seated in the seat 2I, if so desired, initially, and then further threaded to further tighten the clamp upon the organ, if so desired. Such procedure may be desirable where, for example, there is a shrinkage in the organ. The clamp may be manufactured at low cost from relatively inexpensive plastic or other raw materials so that it may be purchased for one use only, if desired. The serrations 25, 26 are preferably of triangular outline as shown in Fig. 2 in the general contour of tetrahedrons to present relatively long apices.

Having thus described my invention, what I 3 claim as new and desire to secure by Letters Patent is:

A funis clamp comprising a pair of coextensive elongated jaw members of substantially uniform width longitudinally, means pivotally connecting said jaw members together at the inner ends for movement'I thereof into superposed contacting relation, the inner faces of said jaws being complementarily serrated to have binding intertting meshing engagement when the clamp is closed, an outwardly directed, open, U-shaped nosing at the outer end of one of said jaw members said nosing having a circular recess, a stem pivotally mounted on the outer end of the other jaw for swinging movement into theopemng of said nosing when the jaws are broughtktogether to contacting relation, a latch closure member having a lower end formed complementaiily to said recess and complementary means on said stem and closure member for moving the latter along said stem and against the recessed portion of the nosing, thereby latching and tightly clamping the inner faces of the jaws against each other.
