Abstract
A vein harvesting device is disclosed. The vein harvesting device includes a handle assembly, an elongated portion extending distally from the handle assembly and defining a longitudinal axis, an end effector, and a retractor. The end effector is disposed adjacent a distal portion of the elongated portion, and includes a first jaw member and a second jaw member. At least one jaw member is movable toward the other jaw member. The retractor is disposed in mechanical cooperation with the elongated portion, and includes a shaft and a pair of legs. The retractor is movable from a non-deployed position where the shaft is aligned with the longitudinal axis, to a deployed position where the shaft is disposed at an angle with respect to the longitudinal axis.

A vein harvesting device, comprising:
- a handle assembly;
- an elongated portion extending distally from the handle assembly and defining a longitudinal axis;
- an end effector disposed adjacent a distal portion of the elongated portion, the end effector including a first jaw member and a second jaw member, at least one jaw member movable toward the other jaw member;
- and
- a retractor disposed in mechanical cooperation with the elongated portion, the retractor including a shaft and a pair of legs, the retractor movable from a non-deployed position where the shaft is aligned with the longitudinal axis, to a deployed position where the shaft is disposed at an angle with respect to the longitudinal axis.
A method of endoscopically harvesting the saphenous vein and surrounding pedicle, the method comprising:
- using a vein harvesting device including:
- a handle assembly;
- an elongated portion extending distally from the handle assembly and defining a longitudinal axis;
- an end effector disposed adjacent a distal portion of the elongated portion, the end effector including a first jaw member and a second jaw member, at least one jaw member movable toward the other jaw member;
- and
- a retractor disposed in mechanical cooperation with the elongated portion, the retractor including a shaft and a pair of legs;
- endoscopically inserting at least a portion of the vein harvesting device adjacent the saphenous vein of a patient;
- at least one of sealing and cutting tissue with the end effector of the vein harvesting device;
- deploying the retractor of the vein harvesting device from a non-deployed position where the shaft is aligned with the longitudinal axis, to a deployed position where the shaft is disposed at an angle with respect to the longitudinal axis;
- positioning the legs of the retractor into contact with at least one the saphenous vein and pedicle to be removed;
- and
- removing at least a portion of the saphenous vein and pedicle from the patient.
