Reusable electrode and disposable sheath
First Claim
1. An electrical ablation device, comprising:
- a first elongate body, the first elongate body comprising an insert having a proximal end and a distal end;
a second elongate body, the second elongate body comprising;
a proximal portion comprising an electrically insulative sheath having a proximal end and a distal end, wherein the sheath defines a first bore configured to receive at least a portion of the insert;
two or more rotatable guides located within the first bore of the sheath and rotably fixed relative to the sheath defining a cross-section within the first bore configured to rotably receive the insert, wherein the two or more rotatable guides define a cross-section within the first bore configured to rotably receive the insert, and when the insert translates through the cross-section, the two or more rotatable guides rotate relative to a surface of the insert;
an electrically conductive portion configured to receive electrical energy from the first elongate body; and
a distal portion comprising an electrode having an energy delivery surface configured to contact tissue and apply electrical energy, wherein the electrode is configured to receive electrical energy from the electrically conductive portion; and
a mating element configured to mate the first and second elongate bodies when the at least a portion of the insert is inserted through the proximal end of the sheath and received within the first bore.

Abstract
A surgical instrument, such as an electrical ablation device, including a first elongate body having an insert and a second elongate body having an electrically insulative sheath that defines a bore. A mating element mates the elongate bodies when at least a portion of the insert is received within the bore. The second elongate body is configured to receive electrical energy from the first elongate body and transmit the electrical energy to an electrode. In certain embodiments, the electrical ablation device may include first and second elongate bodies. The first includes an electrically conductive insert configured to electrically couple to an energy source and apply the electrical energy to tissue, and the second includes an electrically insulative sheath defining a bore configured to receive the insert therethrough and move proximally or distally relative to the insert.
