A smoke evacuation device is disclosed for use with a handheld surgical instrument, which includes an elongated tubular body having opposed proximal and distal end portions, wherein the proximal end portion of the tubular body is adapted and configured for communicating with a source of suction and the distal end portion of the tubular body is adapted and configured to intake smoke generated at a surgical site, and attachment means for attaching the tubular body to the handheld surgical instrument.

An arthroscopy system includes both a motorized handpiece and a detachable probe. The motorized handpiece includes a rotating driver which is configured to engage a rotatable drive coupling within a hub of the probe. The probe has a shaft with an articulating distal region, and the rotatable drive coupling is configured to convert the rotary motion of the rotating driver to an articulating motion within the articulating region of the probe.

A medical instrument sheath including an elongated hollow tube having a wall comprised of polymeric material; and at least one electrical lead embedded inside the wall, wherein the at least one electrical lead is configured to be connected with a respective electrode disposed in a member located inside the sheath and extending from a distal end of the sheath.

A method of treating tissue of a patient uses a device including a mother case, a belt, at least one treatment unit and at least two applicators. The treatment method may include attaching first and second applicators to the belt at a working distance to the patient's surface, and providing different treatment energy to the first applicator and the second applicator. A treatment pattern is created by the applicators providing the different treatment energies. The hardware pattern or positions of the applicators on the belt may be changed before and/or during the treatment. The hardware pattern may be based on selected treatment effect and body part.

An electrosurgical device with an electrode having a first portion whose exterior is electrically uninsulated, a second portion whose exterior is electrically insulated, and a third portion. The device includes an elongated hollow body formed by a first member and a second member. The second member is capable of rotating relative to the first member. The hollow body has an internal cavity, a front end, a rear end, an external surface, and an electrical wire arranged within the body. The hollow body is configured to reversibly receive the third portion of the electrode at the front end of the body such that electrical contact is made between the electrode and the electrical wire and the second portion of the electrode is not surrounded by the hollow body. A first button is provided for controlling a current flow at a first level to the electrode and is arranged on the external surface. A vacuum tube is slidably engaged by the body and has an inlet generally facing the front end and adjacent the electrode. A vacuum outlet port is arranged near the rear end of the body, and the outlet port, internal cavity, and vacuum inlet are in fluid communication with each other.

The disclosure provides a flexible cryoablation needle device resistant to a low temperature and a high pressure, a threaded part is arranged on the outer wall of a liner pipe to enhance a connection strength between the liner pipe and a flexible pipe structure. Since an annular protrusion portion is arranged on the outer wall of the liner pipe, further leakage of a gas coming from a pressure relief process is prevented and the connection strength is enhanced as well. Air tightness and connection strength are further guaranteed by radial extrusion of extruding pipes. And an inner cavity in a cutter head is directly subjected to pressure relief through a cutter head vent, a pressure relief intermediate cavity, a liner vent, a flexible pipe vent and a pressure relief gap.

An illuminated energy device comprising a handle, an illumination element coupled to the handle and disposed continuously and circumferentially about an electrosurgical tip, the electrosurgical tip at a distal end of the handle. The illumination element is preferably adjustably coupled to the handle, and adjustment of the illumination element moves a distal end of the illumination element closer to or further away from a target such as tissue in a surgical field.

A knife configured for use with an electrosurgical forceps having curved jaw members and a method of manufacturing the same. The knife includes a distal body having an inner side and an outer side, a first etching on the outer side of the distal body defining a distal cutting edge and a second etching on the outer side of the distal body extending along a portion of a length of the distal body to define relatively protruded and relatively recessed surfaces extending along a portion of the length of the distal body on the outer side thereof.

Disclosed herein are various embodiments of electrosurgical devices. In one embodiment a removable tip for use with an electrosurgical tool comprises a first tip member having a proximal end and a distal end; a second tip member having a proximal end and a distal end; an actuator coupled to the first tip member and the second tip member, the actuator for moving the first and second tip members between a closed position where the distal end of the first tip member and the distal end of the second tip member are proximate one another, and an open position where the distal end of the first tip member and the distal end of the second tip member are separated by a distance from one another; and an insertion member coupled with the proximal ends of the tip members for inserting the removable tip within an opening in the electrosurgical tool.

A method and apparatus or system are disclosed for a procedure with minimal or no fluoroscopy, for example an electrosurgical procedure, and which uses a three dimensional mapping system. The procedure typically involves electrical measurement of the electrode of a needle to determine its position. Some embodiments further include intracardiac echocardiography (ICE) for tracking devices. The apparatus includes a needle with a tip electrode, an electroanatomical mapping (EAM) system, and an electrical generator, wherein a switching device is used to restrictively electrically connect the needle to only one of the mapping system or generator at a given time.
