Abstract
A method for removing tissues may comprise disposing a tissue resection device at a target tissue site, causing the tissue resection device to resect a core of tissue from the target tissue site, removing the core of tissue from the body, wherein the removing the core of tissue from the body creates a core cavity at the target tissue site.
Claims43
A surgical instrument system for coring tissue from a target tissue site, the system comprising:
- a tissue resection device configured for coring tissue, wherein the device comprises:
- a first clamping element comprising a helical coil, the helical coil including first electrode,
- a second clamping element comprising a second electrode, the second clamping element being positioned to oppose at least a portion of the first clamping element;
- a cutting element configured for the transection of tissue;
- and
- a handle assembly configured to facilitate interaction between tissue and at least one of the first clamping element, the second clamping element, or the cutting element, the handle assembly comprising:
- a rotational control assembly configured to rotate to cause rotation of the helical coil into the tissue;
- a linear actuator, the linear actuator including actuator arms configured to be translated to cause a portion of the tissue to be clamped between the helical coil and the second electrode, the first electrode and the second electrode configured to deliver energy to seal the portion of the tissue clamped between the helical coil and the second electrode,
- the linear actuator configured to be deactivated, after the first electrode and the second electrode deliver the energy, to unclamp the portion of the tissue from between the first clamping element and the second clamping element.
