Appl. No.:

09/472776

Assignee:

Sherwood Services AG - Schaffhausen

International Classification:

G01F 166

US Classification:

7386221

Abstract:

A torque apparatus for the installation and removal of threaded connecting device that employs a plurality of leaf spring elements engaging a plurality of asymmetrical drive teeth sides to establish preset torque values in a hermetically sealed configuration or a variable range of preset torque values in a second configuration. The preset torque values can be readily changed in the second configuration by employing different quantities of leaf springs, differing leaf spring designs, or varying the geometry of the rotor drive teeth. The leaf spring to rotor drive teeth interface provides a slip mechanism to prevent over-torquing when torque values for the installation of a threaded connecting type device is exceeded. While both torque wrench configurations are sterilizable, the torque wrench that is capable of full disassembly for sterilization and use thereafter in a sterilized environment, is reconfigurable for different torque applications without calibration. The wrench can be primarily constructed as disposable device.

International Classification:

A61B 18/14

US Classification:

606 41, 606 45, 606 49

Abstract:

A gas-enhanced electrosurgical instrument includes a hand-held applicator and a portable actuator assembly. The hand-held applicator has a gas delivery member adapted to deliver pressurized ionizable gas to the proximity of an electrode located adjacent a distal end of the applicator. The portable actuator assembly is capable of holding a source of pressurized ionizable gas, such as a cylinder or cartridge, and includes at least one controller to control the delivery of the gas from the source to the hand-held applicator and to control the delivery of electrosurgical energy to the hand-held applicator.

US Classification:

606 41

Abstract:

An electrosurgical apparatus for coagulating tissue includes an elongated housing and an electrode located adjacent the distal end of the housing. The electrode can be connected to a source of electrosurgical energy. At least one actuator is included which electrosurgically energizes the electrode. The apparatus also includes a relatively small gas cylinder which contains a pressurized gas consisting of inert gas and which is selectively seated in the housing. Upon actuation of the actuator, gas is dispersed under pressure from the gas cylinder to the electrode and is ionized prior to the distribution of the gas into the operating field.

International Classification:

A61B 18/00

US Classification:

606 41

Abstract:

A pressure safety system is provided for use with electrosurgical instruments providing pressurized ionized gas to a surgical site. The pressure safety system includes a series of three cascaded pressure change members to control the pressure of gas delivered to a patient. Pressure safety apparatus for use with electrosurgical instruments providing pressurized ionized gas to a surgical site are also provided. Electrosurgical instruments utilizing the pressure safety system and apparatus are also provided. The instruments include a hand-held applicator, a portable actuator assembly and the pressure safety system to control the pressure of gas delivered to a patient.

International Classification:

A61B 18/14

US Classification:

606 41

Abstract:

A ionizable gas system is provided and includes a surgical accessory and a corona start patient connector. The surgical accessory is adapted to receive electrosurgical energy from an electrosurgical energy source and is adapted to receive ionizable gas (e. g. , argon gas) from a portable ionizable gas source. The corona start patient connector is operatively connected to the electrosurgical energy source and the surgical accessory. The corona start patient connector includes an electrical interface that is configured to verify if the ionizable gas system is functioning properly prior to use on a patient.

International Classification:

A61B 18/00

US Classification:

606 41

Abstract:

An electrosurgical instrument for providing pressurized ionized gas to a surgical site includes a hand-held applicator having proximal and distal ends, a gas delivery member adapted to deliver pressurized ionizable gas to the proximity of an electrode located adjacent the distal end of the hand-held applicator. A portable actuator assembly is included that is capable of receiving a source of pressurized ionizable gas therein. The actuator controls the delivery of the gas and energy to the hand-held applicator. A pressure safety connects to the portable actuator and to the hand-held applicator. A pressure safety system having two or more cascaded pressure change members connects between the input port and the output port, the pressure change members are configured to regulate pressurized gas into the environment until the portable actuator assembly exceeds a predetermined threshold.
