ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a ligating clip which is useful for various surgical procedures, particularly for clamping around tissues such as vessels, ducts and the like.
Ligating or ligation clips are well known in the surgical field for use in clamping and thereby ligating various vessels and ducts. This is done so as to control bleeding during surgical procedures.
A large number of disclosures and efforts have been made so to provide satisfactory ligating clips. Despite these efforts, continued problems remain in connection with the provision of ligating clips which are simple and reliable in use, which are easily positioned for proper application, which provide sufficient and reliable closing or ligating of tissues during use, and which can also be removed in a simple procedure.
It is therefore the primary object of the present invention to provide a ligating clip which is easily positioned for use in ligating desired tissues.
It is a further object of the present invention to provide a ligating clip which provides secure clamping of tissues so as to close and reliably stop bleeding of a particular vessel to which the clip is applied.
It is a still further object of the present invention to provide a ligating clip as above which is readily removed from tissues if desired.
Other objects and advantages of the present invention will appear hereinbelow.
SUMMARY OF THE INVENTION
In accordance with the present invention, the foregoing objects and advantages have been readily attained. According to the invention, a ligating clip is provided which comprises a substantially planar head portion; and at least two legs each extending away from said head portion, said head portion biasing said legs into a closed position and being resiliently flexible to allow said legs to be spread to an open position, said head portion having sides extending wider than said legs whereby said sides are engagable for positioning said clip.
The ligating clip of the present invention may be provided including a tissue stop segment for advantageously preventing tissue from passing into a loop of the head portion.
One or both legs of the ligating clip of the present invention can be provided having a plurality of spaced leg segments defining spaces therebetween. The leg segments of respective legs can also be positioned relative to the other legs so as to position opposing legs aligned with spaces. This advantageously allows for occlusion of tissues clamped between the legs of the clip device through compression and diversion or displacement.
The clip of the present invention can be made of resilient elastic wire formed so as to be biased to a closed position, so that legs of the clip can be tensioned to an open position, released to a clamped position, and again tensioned for removal if desired.
