20170273737 · 2017-09-28 · ·

Provided is a connection structure for connecting a treatment component to an operating wire using a coupling member. The treatment component has a rod-shaped proximal end. The coupling member includes a first hole portion into which the proximal end is configured to be inserted on one end, and a second hole portion into which the operating wire is configured to be inserted on the other end. With the proximal end inserted into the first hole portion, the proximal end and the coupling member are joined by swaging and plastically deforming part of the first hole portion. With the operating wire inserted into the second hole portion, the operating wire and the coupling member are joined by swaging and plastically deforming part of the second hole portion. Joint strength between the proximal end and the coupling member is higher than joint strength between the operating wire and the coupling member.

ENDOSCOPIC TREATMENT TOOL

An endoscopic treatment tool includes: a tubular insertion part; a stopper having a through hole and provided at a distal end part of the insertion part; a manipulation wire inserted through the insertion part; a treatment part provided at a distal end part of the manipulation wire and inserted through the through hole; and a restriction member provided closer to a proximal end side than the stopper and connecting the treatment part and the manipulation wire. When the restriction member is pressed against the stopper, the treatment part is locked not to be rotated about an axis of the insertion part with respect to the insertion part, and an opening causing a fluid to flow from an inside of the insertion part to the through hole is formed on an outer peripheral surface of the restriction member.

20170224413 · 2017-08-10 ·

A surgical instrument probe or electrode including an longated cannula with a rod having an end effector on a distal end of the elongated cannula and a pencil hub on a proximal end of the elongated cannula. The end effector on the distal end of the elongated cannula may be a hook or a spatula, and the rod may be attached to an electrosurgical energy source to enable the end effector to perform a cauterizing function. The rod may be between about 100 mm to about 400 mm, and include a diameter of less than about 3 mm.

DEVICES, SYSTEMS, AND METHODS FOR CATARACT PROCEDURES

A cutting device comprising a curved cutting head and an oscillator for use in medical procedures, such as cataract surgery. The cutting head of the cutting device can be sized and shaped to improve precision and reproducibility of incisions made into biological tissue. In some embodiments, a cutting head of the cutting device can comprise a bent distal tip for making incisions into biological tissue, such as a capsule of an eye.

Medical device for cutting

A medical device including an elongate member having a proximal end and a distal end and an end-effector disposed at the distal end of the elongate member is disclosed. The end-effector further includes a plurality of arms, which may pivot or move relative to one another. Further, each arm includes an inner edge defining a cutting edge, and an outer edge having at least one geometric feature for manipulating tissue.

Deployment mechanisms for multi-function surgical instruments

A surgical instrument includes a housing, a shaft, an end effector assembly disposed at the distal end of the shaft, a deployable assembly movable relative to the end effector assembly between a storage position and a deployed position, and a selector assembly. The selector assembly includes a selector member extending from the housing. The selector member is translatable relative to the housing between a first position and a second position. In the second position of the selector member, the selector member is rotatable relative to the housing for transitioning the selector assembly between a first state, wherein the selector member is decoupled relative to the deployable assembly, and a second state, wherein the selector member is coupled to the deployable assembly such that movement of the selector member from the second position to the first position effects movement of the deployable assembly from the storage position to the deployed position.

Deployment mechanisms for multi-function surgical instruments

A surgical instrument includes an end effector assembly having first and second jaw members movable between a spaced-apart position and an approximated position. A trigger assembly is movable between an un-actuated position and an actuated position. An energizable member is selectively movable relative to the jaw members between a first storage position and a first deployed position. At least a portion of the energizable member extends distally from the jaw members in the first deployed position. A selector is operably associated with the trigger assembly and the energizable member. The selector is transitionable between a first state, wherein the energizable member is decoupled from the trigger assembly, and a second state, wherein the energizable member is coupled to the trigger assembly such that movement of the trigger assembly from the un-actuated position to the actuated position effects movement of the energizable member from the storage position to the deployed position.

ARTHROSCOPIC DEVICES AND METHODS

An electrosurgical probe can be detachably secured to a handpiece having a motor drive unit and an RF current contact. The electrosurgical probe includes an elongate shaft having a longitudinal axis, a distal dielectric tip, and a proximal hub which is detachably securable to the handpiece. A hook electrode is reciprocatably mounted in the distal dielectric tip, and an RF connector on the hub is couplable to the RF current contact in the handpiece when the hub is secured to the handpiece. A drive mechanism in the hub mechanically couples to the hook electrode, and drive mechanism engages a rotational component in the motor drive unit when the hub is secured to the handpiece. The drive mechanism converts rotational motion from the rotational component into axial reciprocation and transmits the axial reciprocation to the hook electrode to axially displace the hook electrode between a non-extended position and an extended position relative to the dielectric tip.
