This is a hemostatic clip for clasping the flaps of a wound together and holding them together to prevent bleeding and to promote healing until the wound is healed and in closed position, whereupon it is released. It is made in a generally tubular body form with a longitudinal slit having cooperating teeth on the slit edges. It is made of a suitable resilient metal or plastic material. Opposite the elongate slit, the tubular body is provided with an inwardly extending longitudinal U-shape depression which, when pressure is applied to the sides of the U, will cause the slit and teeth to separate, whereby it can be applied to the wound flaps. When the pressure is released, the teeth will grasp and hold the wound flaps in contact. When the wound has healed sufficiently, the pressure is again applied to release the teeth from engagement with the flaps. Ridges, eyelets or apertures are provided in the tubular body to cooperate with a pair of plyers for applying suitable pressure.

BACKGROUND OF THIS INVENTION
Surgical clips, wound clasps, serrefins, etc. have been known for quite some time for holding the flaps or edges of a wound together to promote healing. They 10 were generally made of deformable metal, not resilient, some of them being provided with teeth to catch in the wound flaps and be bent by a suitable tool to deform the metal into wound flap clasping or holding condition, and then had to be bent or deformed again to release the 15 wound flaps. The amount of pressure they put on the wound flaps was a matter of personal skill and judgment on the part of the physician or operator in applying the clip to the wound edges, and, as such, could be overdone or underdone. > 20
SUMMARY OF THIS INVENTION
This hemostatic clip is made of suitable resilient metal or resilient plastic, capable of being sterilized in a conventional manner, and is generally a tubular body hav- 25 ing a longitudinal slit and has teeth extending from the slit edges. The tubular body is provided with an inverted U-shaped longitudinal portion directly opposite the longitudinal slit. This U-shaped portion is provided with pressure tool cooperating means so that when 30 pressure is applied, the tool holds the slip open for applying the teeth and the slit edges to the flaps of the wound and are self-engaging on the wound flaps when the pressure is released.
The pressure of the teeth and slit edges on the wound 35 flaps is predetermined by the material, size, etc. of the tubular body and is not dependent on the skill of the operator. Tool cooperating means are provided on the tubular body on opposite sides of the inverted U apex, and may be in the form of tool cooperating longitudinal 40 ridges, which, when squeezed together, separate the teeth and slit edges.
In another form, apertures are provided in the tubular body for receiving the plyers, tool fingers and opening the slit for application to the wound flaps. 45
In a third form, eyelets or pockets are provided on the tubular body to receive the plyer tool for opening the flaps.
OBJECTS OF THIS INVENTION 50
It is an object of this invention to provide a selfattaching hemostatic clip having wound flap-engaging teeth for holding the flaps together with a pressure predetermined by the resiliency of the material..
A further object of this invention is to provide a 55 hemostatic clip made of resilient material for applying a . predetermined pressure for holding the wound flaps together.
Yet a further object of this invention is to provide a sterilizable hemostatic clip which is resilient and not 60 deformed in operation or use.
A still further object of this invention is to provide a hemostatic clip which may be provided with different tool cooperating portions for holding it open for application to the wound flaps, the clip then being held in 65 flap holding position by its resiliency and not by being bent or deformed in accordance with the judgment of the particular operator.
Yet a further object of this invention is to provide a reusable hemostatic clip which is never deformed in operation, and which may be sterilized for re-use.
A further object of this invention is to provide a hemostatic clip which is made of suitable sterilizable resilient metal or plastic material which is reuseable, but which is so inexpensive that it may be readily discarded after use, if desired.
Yet a further object of this invention is to provide a hemostatic clip that is an improvement over the prior art, including U.S. Pat. Nos. 733,723; 1,728,316; 2,201,610; 3,068,870; 3,446,212, amongst others.

DETAILED DESCRIPTION OF THIS
There is shown at 10 one form of the elongate tubular body of the hemostatic clip of this invention. This clip 10 is made of suitable sterilizable resilient sheet metal or plastic material. This tubular body 10 is longitudinally slit at 12, and the slit edges 12 have opposed, slightly downwardly extending teeth 14 projecting therefrom, the resiliency of the material normally urging the teeth 14 into engaging contact. Opposite the slit edges 12, an inverted longitudinal U-shaped depression 16 is provided, having a somewhat deep apex 18. Longitudinal ridges 20 join the U-shaped portion 16 to the tubular portions 22, the apex 18 extending below the ridges 20.
These longitudinal ridges are for the purpose of cooperating with the elaws 24 of a pair of crossed arm plyers 26. Due to the position of the apex 18 being below the ridges 20 squeezing the plyers 26 together-with its claws 24 engaged about the ridges 20, it will cause the tubular portions 22 to move away from* each other, separating the teeth 14 and slit edges 12 from each other, permitting such teeth 14 to be applied to the flaps of a sound. Then the pressure on the plyers 26 is slowly lessened, permitting the teeth 14 to be resiliently urged into wound flap engaging position. Then, with the plyer pressure completely released, the teeth 14 remain in inserted contact in the wound flaps, and the slit edges 12 press and hold the wound flaps together in healing
