Claims10
A retractor for holding open skin, comprising:
- a. a unitary piece including movably connected members having points proximate longitudinal extremities of said members separating from each other upon relative movement of said members and means for retaining said members at a position of maximum point separation when said members are urged towards said position of maximum point separation;
- and
- b. resilient elastomeric means for urging said members to move about a position of moveable connection therebetween towards said position of maximum point separation.
A disposable self-retaining skin retractor permitting access to interior tissue, comprising:
- a. longitudinally elongated members moveable respecting one another about a position of connection therebetween, having tip portions remote from said connection position separating from each other upon relative rotary movement of said members;
- and
- b. means for biasing members respecting one another about said connection position towards a position at which said tip portions are maximally separated;
- wherein said connection position is a web and said longitudinally elongated members and said web are an integral single piece of plastic.
