US Patent:

7244256, Jul 17, 2007

Filed:

Jun 10, 2004

Appl. No.:

10/866371

Inventors:

Michael DeCesare - New Port Richey FL, US

Assignee:

Linvatec Corporation - Largo FL

International Classification:

A61B 18/14

US Classification:

606 41, 606 49

Abstract:

An electrosurgical device having an electrode and an insulating piece such as a ceramic insulator is disclosed. The electrode includes an active surface for ablating and/or coagulating tissue in an electrosurgical procedure. The insulating piece surrounds the active surface and provides a barrier for the intense heat created during ablation. The insulating piece is also electrically nonconductive to prevent unwanted discharge of energy. Electrode has a retaining ledge configured to engage a lip formed on the insulating ring. The insulating ring is secured to the electrosurgical device by connecting the electrode to an electrode seat and capturing the insulating piece in between. The electrode can be connected to the electrode seat by projection welding. The insulating piece is connected to the electrode without the use of an adhesive.

Assignee:

Linvatec Corporation - Largo FL

International Classification:

A61B 18/18

US Classification:

606 49, 606 41

Abstract:

An improved electrode for electrosurgery comprises at least one orifice in the active surface of the electrode connected to a lumen in the probe of larger cross-sectional area than the area of the orifice(s), the lumen being connected to a vacuum, such that a venturi is formed extending from the one or more orifices in the active surface of the electrode to the lumen, whereby flow of fluid, ablated tissue, and other debris in the vicinity of the surgical site is accelerated through the orifice(s), reducing clogging, whereby any particle passing through the orifice(s) is unlikely to become clogged downstream, and whereby the edges of the orifice(s) are ablative, tending to reduce any particles caught at the orifice(s) to a size small enough to pass therethrough.

Hugh West - Salt Lake City UT, US
James Logan - Largo FL, US
Michael Decesare - New Port Richey FL, US

International Classification:

A61B018/14

US Classification:

606041000

Abstract:

An electrode configuration for use with a standard electrosurgical generator suitable for performing tissue ablation at relatively low power levels. The electrode has at least one curved wire member at its distal tip, the exposed conductive area of the curved wire member being minimized to create high power densities sufficient for tissue ablation. The exposed conductive area of the wire member is partially surrounded by a ceramic insulating support member to enable ablation laterally of the electrode tip as well as proximally and distally. An insulating layer is applied to portions of the outer surfaces of the electrode and the ceramic insulating support member.

International Classification:

A61B018/14

US Classification:

606041000

Abstract:

Electrosurgical devices for ablating tissue and methods of making the same are disclosed. The electrosurgical devices include an electrode with a lumen for aspirating gasses and debris produced during surgery. The electrode also includes a plurality of upper active edges for ablating tissue in an electrosurgical procedure. The upper active electrodes are spaced apart to form a filter that filters out large tissue particles from being aspirated into the lumen. The upper active edges ablate the large particles to form particles that can pass into the lumen. A lower active edge is formed at the terminal end of the lumen for ablating tissue being aspirated into the lumen. The lower active edge prevent tissue particles from occluding the opening to the lumen.

Abstract:

A single cell power unit for a motorized surgical power tool includes a single cell power unit enclosure. A high temperature battery cell is mechanically supported within and disposed at about a center of the single cell power unit enclosure. An electrical connector having a plurality of connector pins is configured to couple to a mating electrical connector of a tool part having a motor. A motorized surgical handpiece tool which prevents the motor from operating when the power unit is removed, a method to start a multi-phase brushless sensorless motor of a surgical hand piece tool in a controlled manner, a power unit for a motorized surgical power tool with a battery insulated by a flexible circuit boards, and a safety switch system for a motorized surgical power tool with a lever magnet motor speed control are also described.
