Claims22
A trocar system comprising:
- a handle having a first end and a second end;
- a trocar disposed adjacent the second end of the handle;
- a plurality of cannulas disposed on the trocar simultaneously;
- and
- a drive system disposed for forward movement of the cannulas in a longitudinal direction away from the first end of the handle.
A trocar system comprising:
- a handle having a first end and a second end;
- a trocar disposed adjacent the second end of the handle;
- at least one cannula disposed on the trocar;
- and
- a drive system disposed for forward movement of the at least one cannula in a longitudinal direction away from the first end of the handle, the drive system including a drive member and a biasing member connected to the drive member to bias the drive member against forward movement in the longitudinal direction.
A method of using a trocar system to insert a cannula into an incision formed in a portion of a patient's body, the trocar system comprising a handle, a drive member, an actuating member, a trocar, and a plurality of cannulas disposed on the trocar simultaneously, the method comprising:
- inserting the trocar into an incision in a portion of the patient's body;
- inserting a first cannula of the plurality of cannulas into the incision such that the first cannula is disposed between the incision and the trocar;
- and
- actuating the actuating member, wherein actuation of the actuating member engages a tooth on the drive member and moves the drive member forward in a longitudinal direction, wherein forward movement of the drive member results in forward movement of a second cannula of the plurality of cannulas to a position adjacent an end of the handle.
