SURGICAL CLAMP Filed Sept. 19, 1963 MHZ/541V 6247/0/16 INVENTOR.

United States Patent 3,210,816 SURGICAL CLAMP Bette Jean Clemons, 1947 E. Earl] Drive, Phoenix, Ariz. Filed Sept. 19, 1963, Ser. No. 310,017 21 Claims. (CI. 24-73) This invention relates to a clamp for holding tubes or cords and more particularly relates to such a clamp for holding tubes and cords in place during a surgical operation.

In many surgical operations it is necessary to provide various tubings and electrical cords in the vicinity of the incision. For example, one or more suction tubes must often be provided to remove blood and other body fluids from the operating region. For this purpose, a sterile section of tubing and a special sterile metal suction tip are employed, the sterile suction tubing connecting with an unsterile length of tubing leading to the vacuum drawing machine somewhere below the sterile range of the sheets or drapes that cover the patient and the operating table. It is often also necessary to provide an electro-cautery cord for use in the operation.

The sterile suction tubing must be attached to the sheets in some manner to prevent the tubing from sliding off of the sterile field onto the floor. The device now commonly used to accomplish this end is known as a towel clip. A towel clip is similar to a pair of scissors but instead of cutting blades, the towel clip is provided with a pair of sharp teeth which puncture the sheet as they close around it. The finger holes of the towel clip are employed to hold the tubing by passing the tubing through the loops.

Since the teeth of a towel clip puncture the sheet, a sudden yank or the like often results in the tearing of the sheet. The puncturing of the sheet is itself a dangerous practice as it risks contamination of the sterile field. The manner in which the tube is passed through the loops also tend to cause kinking of the tubing with subsequent loss of pressure diiferential. Moreover, since each towel clip is only capable of handling one tube, if more than one are necessary the number of towel clips is multiplied and the operating field is somewhat cluttered.

According to the present invention, a single clamp is provided that is capable of holding a plurality of lengths of tubing or electrical cords which may be necessary during the performance of an operation. The clamp may be secured to the sheets or drapes without piercing them and thus does not present the problem of tearing the sheets or the risk of contaminating the field. The clamp is easily engaged and disengaged with the sheets, and the tubes or cords are easily engaged and disengaged with the clamp so that the clamp is extremely easy and convenient to use. Should the tubing have to be. changed during an operation for any reason, this may easily be accomplished without disturbing the clamp itself.

It is therefore an object of the present invention to provide a clamp for securing tubes or cords.

It is also an object of the present invention to provide such a clamp for securing the tubes and cords used during a" surgical operation.

It is another object of the presentinvention to provide such a clamp which may be easily attached to the sheets draped'over the patient .or operating table without piercing or tearingthe sheets.

These and. other objects and advantages of the present invention will become apparent upon reference to the accompanying description and drawings in which:

FIGURE 7 illustrates the clamping action of a clamp of FIGURE 5.

FIGURE 8' is a plan view' of a modification of the portion of the clamp common to all three embodiments.

Referring now to FIGURES 1 and 2, there is shown a first embodiment of a'surgic'al clamp according to the present invention; In this embodiment, the clamp is formed of a single strip ofresilient material 10 in which has been stamped a plurality ofholes 11, 12 and 13. Theholes 11 and 13 are shaped with generally,circular portions 14 and 15 at either end thereof and a connectingslot 16 joining thecircular portions 14 and 15, theslot 16 being considerably narrower than the diameter of thecircular portions 14 and 15. If desired, theslot 16 can be provided with a slightly enlargedportion 17 in its central region.

Thehole 12 is also provided withcircular end portions 18 and 19 and a connectingslot'20, the slot20 having a lateral dimension less than the diameter of thecircular portions 18 and 19.

After the strip ofmaterial 10 has'been stamped with the'holes 11, 12 and 13, it is folded to have abase member 23, anupper member 24, and connectingleg members 25 and 26: Theseleg members 25 and 26 are formed by folding the material along a line dividing the slots and 20, thus providing this portion of the strip with the shape of an inverted V. Theupper member 24 isprovided with a dependingflange 27 which is adapted to cooperate with a generally V-shaped trough 28 formed at the end of thebase member 23 thus forming apair of jaws. The bend or hinge 29 joining thebase member 23 andleg 26 is such that in the rest position theflange 27 is biased away from thetrough 28 so that the jaws are partially open. 7 p

Thebase member 23 is provided with a suitable opening through which extends abolt 32 having. athreadedupper portion 33. The-bolt 32 ispreferably weldedor otherwise bonded to thebase m'em ber 23. Theupper member 24 is also provided with a hole for receiving the threadedportion 33 of thebolt 32. Asuitable nut 34 is then threaded on to the threadedportion 33 of thebolt 32 and the end of the bolt-flattened so the nutcan not be removed. The cylindrical portions18 and 19 of the hole 12- are preferably provided witharcuate grommets 35 and 36 of a low friction materialsuch as-polytetrafluoroethylene. Similar grommets could be used in the other holes if desired, the sire of the interior diameter of the grommets being changeable to handle difierent size tubing.

In operation, the so called sterile nurse or other attendant makes a horizontal fold in one of the sterile sheets and inserts the fold between theflange 27 and--trough 28. Thenut 34 is then-tightened on the bolt 32- until theflange 27 and trough-28 firmly grasp the fold of the sheet between them. The attendant then pinches the lengths of tubing at appropriate points with -1'espectto' the operating area andthe vacuum pump. The pinched slots 20 ofthehole 12 into the grommets-35 and-36-whereit will be held inplace without damage to itsinsulation.

Referring now to FIGURES 3 and 4, a second embodiment of the clamp of the present invention is illustrated. In this embodiment, two separate strips ofresilient material 40 and 41 are used. Thestrip 40 hasholes 42, 43 and 44 similar to theholes 11, 12 and 13 of FIG- URES 1 and 2 formed therein. One end of thestrip 40 is separated into threeportions 45, 46 and 47. Theflanking portions 45 and 47 are bent under thestrip 40 and have their ends bent backward at 48 to be roughly parallel to thestrip 40. The end of themiddle portion 46 is bent upward at 49. Thestrip 40 itself is bent along the center line of theholes 42, 43 and 44 to have the general shape of an inverted V.

Thesecond strip 41 has amain portion 50, and up standingflange 51 at one end of themain portion 50, and atongue 52 extending from the other end of themain portion 50. A pair ofdents 53 and 54 are formed in the underside of themain portion 50 on either side of thetongue 52. These dents 53 and 54 serve to receive theends 48 of theportions 45 and 47 of thefirst strip 40 while theupstanding flange 51 prevents movement of the rear leg of thestrip 40. This action causesportion 46 of thestrip 42 to firmly engage thetongue 52 of thestrip 41. Theportion 46 andtongue 52 can be forced apart to receive a fold of a sheet and then released to engage it firmly. The tubing and cords are inserted in the same manner as in FIGURES 1 and 2.

FIGURES and 6 show a third embodiment of the clamp of the present invent-ion. In this embodiment a first strip ofresilient material 58 hasholes 59, 60 and 61 formed therein in the same manner as in the previous embodiments. Thestrip 58 is folded to formlegs 62 and 63, theleg 62 having anextension 64 bent at a slight angle with theleg 62. Theextension 64 is provided with aslot 65 and has a plurality of bumps ordimples 66 formed near its outer end.

A second strip of resilient material 67 cooperates with thefirst member 58 and is provided withlegs 68 and 69, theleg 69 having anupstanding flange 70 which is preferably spot welded to theleg 63 of themember 58. Theleg 68 is provided with acurved portion 71 which extends through theslot 65 in theextension 64 and is provided at its outer end, which is approximately parallel with theextension 64, with a plurality ofindentations 72 which correspond to, and cooperate with, thedimples 66 on theextension 64. Alatch 73 is mounted on theleg 62 of themember 58 by means of a rivet or suitable fastening means 74 and is restrained from easy movement by a spring washer 75.

As can readily be seen, the clamp of FIGURES S and 6 is opened by turning thelatch 73 out of engagement with theportion 71 of the member 67. The fold of the sheet is then inserted between thisportion 71 and theextension 64 of themember 58. The latch is then turned to the locking position to firmly maintain the sheet between the two members. Thedimples 66 andindentations 72 cooperate to enhance this action. The action of this mechanism can be seen in FIGURE 7 which shows the latched position in solid lines and the unlatched position in dotted lines.

FIGURE 8 illustrates a modification that may be made to any of the clamps previously described. In this figure, each of theholes 11 and 13 have been modified to accommodate tubing of various different diameters. As can be seen, thecircular portions 14 and at either end of the hole are joined byslots 76, 77, 78 and 79 to furthercircular portions 80, 81, 82 and 83 respectively. After the strip is bent into shape, whatever size tubing is to be used can be inserted through the appropriate slots into the corraponding size circular portion. As an example, thecircular portions 14 and 15 may have diameters of /2 inch, thecircular portions 80 and 82 may have diameters of A inch and thecircular portions 81 and 83 may have diameters of /1 inch. The connecting slots would be correspondingly scaled, theslots 16 having a width of inch, theslots 76 and 78 having a 4 width of 7 inch and theslots 77 and 79 having a width of 7 inch. If desired, the various circular portions in each end of theholes 11 and 13 may be aligned in a straight line, either vertically, horizontally or at an angle rather than in the offset positions shown.

As can be seen from the foregoing description, a clamp has been provided which is capable of quick and easy engagement or disengagement with a sheet of the type used to cover patients or operating tables. The clamp is capable of holding a plurality of lengths of tubing of -any pliable wall material for suction or other purposes and is also capable of holding whatever electrical cords may be necessary in the performance of the operation. The provision of a single device for holding a plurality of tubes and cords permits the rapid removal of all this apparatus as a unit at the end of an operation, a time when speed may be vital. While each of the clamps illustrated is provided with means for holding tubes and one cord, it is obvious that the clamps may be modified to hold any number of tubes and cords. It should also be obvious that latching devices other than those shown may be used within the scope of the present invention.

The invention may be embodied in other specific forms not departing from the spirit or central characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
