- This invention relates to clamping devices, and more particularly to devices of such type which may be used by the surgeon, as a funis clamp.
- a principal object of the invention is to provide a funis clamp which can be quickly and easily applied by the surgeon with one hand and which does not require the use of a tool for its application.
- Another object of the invention is to provide a funis clamp which is fabricated of a single piece so as to have no moving parts and which, therefore, can be quickly and effectively sterilized.
- a still further object of the invention is to provide a funis clamp of the type described, which is self-adjusting once operatively positioned and functions to automatically maintain a sufiicient pressure on the cord or other material being clamped even though the latter has shrunk or diminished in size.
- Another object of the invention is to provide a clamp which has incorporated therein a positive locking feature so that the clamp automatically locks itself once set in operative position thereby preventing accidental removal of the clamp before the expiration of a predetermined time.
- a still further object of the invention is to provide a funis clamp, of the type described which, due to its unique simplicity of design, can be manufactured inexpensively and therefore can be marketed as a disposable item.

- the device constituting this invention comprises a pair of arms 8 and 9 secured together at their one end by a hinge portion 10 which is arcuately shaped in order to equalize the stress imparted thereto.
- the arms 8 and 9 are each provided with thumb depressor surfaces 12 and 13, respectively.
- the arms 8 and 9 are further provided with a plurality of teeth 14 and 15, respectively, which are disposed so that the teeth 14 mesh with the teeth 15.
- the arm 9 has at its free end a flattened extension 16 having an oval-shaped hole 17 extending 3,294,636 Patented Sept. 7, 1965 therethrough in the form of a spiral configuration.
- the hole 17 has, therefore, an entrance 18 having a longitudinal axis angularly disposed relative to the longitudinal axis of its exit 19. It is preferable that the angular relation between the longitudinal axes be approximately 45 degrees.
- a tapered guide notch 20 is'provided in the inner surface of the extension 16 and communicates with the entrance 18.
- a recess 21 is provided on the outer surface of the extension 16 and communicates with the exit 19.
- a lateral projection 22 is formed at the free end of the arm 8 and terminates in an oval-shaped button 23 having tapered sides 24.
- the surgeon should, with the clamp in an open position, locate the cord so that it is positioned between the arms 3 and 9 and as near the hinge portion 10 as is practical. With the clamp in one hand the surgeon may then exert pressure by depressing the thumb depressor surfaces 12 and 13. This can best be accomplished by using the thumb and forefinger. The arms 8 and 9 are thereby moved into a closed position and the teeth 14 and 15 function to prevent any slippage between the cord and the arms 8 and 9.
- the compression exerted by the hand of the operator as above mentioned is suflicient to interlock the free ends of the arms 8 and 9. Since the oval-shaped button 23 is in substantial registration relative to the entrance 18 of the oval-shaped hole 17, it may freely enter the entrance 18 thereof and traverse the thickness of the flattened extension 16, finally emerging through the exit 19. In passing through the hole 17, the button 23 is caused to be rotated approximately 45 degrees due to the spiral configuration therein. Being that the exit 19 of the hole 17 is disposed so that its longitudinal axis is angularly related to the longitudinal axis of the entrance 18, the button 23 is locked in position and is prevented from returning back through the hole 17.
- the physical characteristics of the lateral projection 22 cause the latter to counter-rotate so that the button 23 assumes its normal position in substantial registration with the entrance 18.
- the size of the button 235 is preferably slightly smaller than the size of the hole 17.
- the tapered sides 24 of the button 23to function to facilitate the passage of the button 23 through the hole 17.
- the tapered notch 20 obviously functions to guide the passage of the button 23 toward the entrance 18 of the hole 17.
- the compression of the cord 25 is sufficient so as to produce hemostasis as is well known to those skilled in the art. Due to the flexible and somewhat elastic properties of the material from which the clamp is fabricated, it has the characteristic of being automatically compensating for any shrinkage in the cord 25. As the clamp is applied and compresses the cord as shown in FIGURE 4, the loop 10 becomes somewhat expanded because of the interposition of the cord between the arms. This exerts a constant clamping pressure on the cord. Thereafter, as the cord diminishes in size, the arms 8 and 9 move closer together and continue to maintain the required pressure on the cord 25. After the clamp has been in position on the cord for a predetermined period of time it may be easily removed by severing the projection 22 adjacent to the button 23, or by cutting through the substance of the hinge 10.
- the funis clamp described herein has been found extremely satisfactory when fabricated of plastic, it may, of course, be produced from other materials which have the physical characteristics of being relatively flexible, elastic, and of sufiicient strength. When fabricated of plastic the clamp may be produced by mass production techniques at an extremely low cost and, therefore, may be marketed as an inexpensive disposable item.
- a funis clamp has been provided which can be applied by the surgeon quickly With one hand and Without the necessity of utilizing other tools, such as a forceps. Furthermore, the operator does not require assistance from anyone else in its application. Since the device is a unitary piece and has no moving parts, it may be sterilized very simply. It should be noted that the interlocking mechanism incorporated in the device precludes the possibility of the arms 8 and 9 being accidentally disengaged, thereby releasing the pressure prematurely.

Smith, both of 1577 South Ave., Rochester, N. Continuation of application Ser. No. 722,516, Mar. 19, 1958. This application Aug. 30, 1961, 'Ser. No. 137,936 1'4Claims. ('Cl. 128-346) This application is a continuation of our copending application Serial No. 722,516, filed March 19, 1958, now abandoned.
This invention relates to clamping devices, and more particularly to devices of such type which may be used by the surgeon, as a funis clamp.
A principal object of the invention is to provide a funis clamp which can be quickly and easily applied by the surgeon with one hand and which does not require the use of a tool for its application.
Another object of the invention is to provide a funis clamp which is fabricated of a single piece so as to have no moving parts and which, therefore, can be quickly and effectively sterilized.
A still further object of the invention is to provide a funis clamp of the type described, which is self-adjusting once operatively positioned and functions to automatically maintain a sufiicient pressure on the cord or other material being clamped even though the latter has shrunk or diminished in size.
Another object of the invention is to provide a clamp which has incorporated therein a positive locking feature so that the clamp automatically locks itself once set in operative position thereby preventing accidental removal of the clamp before the expiration of a predetermined time.
A still further object of the invention is to provide a funis clamp, of the type described which, due to its unique simplicity of design, can be manufactured inexpensively and therefore can be marketed as a disposable item.
With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
The invention is illustrated in the accompanying drawing, wherein:
FIGURE 1 is a side elevational view of the novel clamp constituting this invention.
' FIGURE 2 is a top plan view of the device.
FIGURE 3 is an end view of the device.
FIGURE 4 is an elevational view of the device shown in operative position securing therein material to be clamped such as an umbilical cord.
FIGURE 5 is an enlarged fragmentary plan view of the free end of one arm of the device.
FIGURE 6 is an enlarged fragmentary elevational view of the free end of the other arm of the device.
FIGURE 7 is a sectional view taken along lines 77 of FIGURE 6.
The device constituting this invention comprises a pair of arms 8 and 9 secured together at their one end by a hinge portion 10 which is arcuately shaped in order to equalize the stress imparted thereto. The arms 8 and 9 are each provided with thumb depressor surfaces 12 and 13, respectively. The arms 8 and 9 are further provided with a plurality of teeth 14 and 15, respectively, which are disposed so that the teeth 14 mesh with the teeth 15. The arm 9 has at its free end a flattened extension 16 having an oval-shaped hole 17 extending 3,294,636 Patented Sept. 7, 1965 therethrough in the form of a spiral configuration. The hole 17 has, therefore, an entrance 18 having a longitudinal axis angularly disposed relative to the longitudinal axis of its exit 19. It is preferable that the angular relation between the longitudinal axes be approximately 45 degrees.
A tapered guide notch 20 is'provided in the inner surface of the extension 16 and communicates with the entrance 18. A recess 21 is provided on the outer surface of the extension 16 and communicates with the exit 19.
A lateral projection 22 is formed at the free end of the arm 8 and terminates in an oval-shaped button 23 having tapered sides 24.
In using this novel device to clamp an umbilical cord, such as the cord 25 as is illustrated in FIGURE 4, the surgeon should, with the clamp in an open position, locate the cord so that it is positioned between the arms 3 and 9 and as near the hinge portion 10 as is practical. With the clamp in one hand the surgeon may then exert pressure by depressing the thumb depressor surfaces 12 and 13. This can best be accomplished by using the thumb and forefinger. The arms 8 and 9 are thereby moved into a closed position and the teeth 14 and 15 function to prevent any slippage between the cord and the arms 8 and 9.
The compression exerted by the hand of the operator as above mentioned is suflicient to interlock the free ends of the arms 8 and 9. Since the oval-shaped button 23 is in substantial registration relative to the entrance 18 of the oval-shaped hole 17, it may freely enter the entrance 18 thereof and traverse the thickness of the flattened extension 16, finally emerging through the exit 19. In passing through the hole 17, the button 23 is caused to be rotated approximately 45 degrees due to the spiral configuration therein. Being that the exit 19 of the hole 17 is disposed so that its longitudinal axis is angularly related to the longitudinal axis of the entrance 18, the button 23 is locked in position and is prevented from returning back through the hole 17. It should be obvious, of course, that the physical characteristics of the lateral projection 22 cause the latter to counter-rotate so that the button 23 assumes its normal position in substantial registration with the entrance 18. The size of the button 235 is preferably slightly smaller than the size of the hole 17. Furthermore, it should be noted that the tapered sides 24 of the button 23to function to facilitate the passage of the button 23 through the hole 17. The tapered notch 20 obviously functions to guide the passage of the button 23 toward the entrance 18 of the hole 17. When the clamp is in its closed position, as can be best seen in FIGURE 4, the button 23 is accommodated within the recess 21 so that a substantially flush relationship exists between the surface of the button 23 and the outer surface of the extension 16.
The compression of the cord 25 is sufficient so as to produce hemostasis as is well known to those skilled in the art. Due to the flexible and somewhat elastic properties of the material from which the clamp is fabricated, it has the characteristic of being automatically compensating for any shrinkage in the cord 25. As the clamp is applied and compresses the cord as shown in FIGURE 4, the loop 10 becomes somewhat expanded because of the interposition of the cord between the arms. This exerts a constant clamping pressure on the cord. Thereafter, as the cord diminishes in size, the arms 8 and 9 move closer together and continue to maintain the required pressure on the cord 25. After the clamp has been in position on the cord for a predetermined period of time it may be easily removed by severing the projection 22 adjacent to the button 23, or by cutting through the substance of the hinge 10.
Although the funis clamp described herein has been found extremely satisfactory when fabricated of plastic, it may, of course, be produced from other materials which have the physical characteristics of being relatively flexible, elastic, and of sufiicient strength. When fabricated of plastic the clamp may be produced by mass production techniques at an extremely low cost and, therefore, may be marketed as an inexpensive disposable item.
Thus, a funis clamp has been provided which can be applied by the surgeon quickly With one hand and Without the necessity of utilizing other tools, such as a forceps. Furthermore, the operator does not require assistance from anyone else in its application. Since the device is a unitary piece and has no moving parts, it may be sterilized very simply. It should be noted that the interlocking mechanism incorporated in the device precludes the possibility of the arms 8 and 9 being accidentally disengaged, thereby releasing the pressure prematurely.
Although the funis clamp constituting this invention has been described herein in reference to its use as a means for clamping an umbilical cord, its scope and application is sutficiently diversified to include the clamping of other organs or materials which may require a positive action clamping device.
