Patent ID: 11931067

Abstract:
A tissue guard includes an elongated body having a proximal end and a distal end and defining a lumen therethrough. A plurality of torsion springs is included, each torsion spring having a first leg and a second leg and a spring defined therebetween. The first leg of each torsion spring is operably engaged to the distal end of the elongated body. Two or more petals extend from the distal end of the elongated body, each petal is operably engaged to the second leg of one of the torsion springs. The petals are movable between a first, compressed configuration wherein the petals are compressed relative to one another against the bias of the plurality of torsion springs to facilitate insertion of the tissue guard within an access device or natural orifice and a second, expanded configuration to facilitate engagement of the petals beneath the access device or within the natural orifical to secure the tissue guard therein.
