Endoscope forceps contains: a coil member having a distal end and a proximal end and including a lumen, the coil member made of a metal and having flexibility; a tubular member including a lumen and disposed in the lumen of the coil member; a pair of forceps members disposed on a distal side relative to the coil member, and openable and closable; connection members respectively connected to portions on a proximal side of the pair of forceps members; and a stranded wire inserted through the lumen of the tubular member and including a connection portion connected to proximal end portions of the connection members, wherein the distal end of the coil member is located between a distal end of the tubular member and the connection portion at which each connection member is connected to the stranded wire.

Apparatus for performing a minimally-invasive procedure, the apparatus comprising: a tool comprising: a shaft having a distal end and a proximal end; a handle attached to the proximal end of the shaft; and an end effector attached to the distal end of the shaft; wherein the shaft comprises a flexible portion extending distally from the proximal end of the shaft, and an articulating portion extending proximally from the distal end of the shaft, and wherein the articulating portion comprises a flexible spine; wherein a plurality of articulation cables extend through the shaft from the handle to the flexible spine, such that when tension is applied to at least one of the plurality of articulation cables, the flexible spine bends; wherein a rotatable element extends through the shaft from the handle to the end effector, such that when the rotatable element is rotated, the end effector rotates; and wherein an actuation element extends through the shaft from the handle to the end effector, such that when the actuation element is moved, the end effector is actuated.

A surgical instrument includes a housing and an elongated shaft operably coupled to an actuating mechanism moveable between an actuated position and an unactuated position. An end effector includes a pair of opposing first and second jaw members. One or more drive surfaces are disposed on the actuating mechanism and configured to compress a spring upon movement of the actuating mechanism to the actuated position. The spring imparts a spring force in a distal direction to bias the actuating mechanism to the unactuated position. An electrically conductive tissue sealing surface extends along a length of one or both of the jaw members and is adapted to connect to a source of electrosurgical energy.

Surgical instruments with rotation stop devices and related methods are disclosed herein, e.g., for providing limited rotation between first and second components of the surgical instrument in a range greater than 360 degrees. Exemplary rotation stop devices can have a low profile and can include various features to facilitate packaging of the device within a larger instrument.

A device comprising: (a) a first working arm; (b) a body; (c) a shuttle, and (d) a bias device; wherein the bias device biases the first working arm relative to the body when the shuttle is in a first position, and wherein the bias device is free of biasing the first working arm relative to the body when the shuttle is in a second position.

A surgical instrument comprising a shaft and an end effector is disclosed. The end effector is releasably attachable to the shaft by a lock biased into a locked condition to hold the end effector to the shaft.

A sensor system includes a first member extending along a rotational axis and having a surface disposed circumferentially about the axis. The sensor system further includes a conductive element fixed to the first member and disposed on the surface and about the rotational axis and a second member extending along the axis. A rotational position between the first member and the second member is adjustable. The sensor system further includes a target mounted to and rotatable with the second member and being movable relative to the second member between first and second positions. The target is spaced apart from the conductive element in both the first and second positions and is closer to the conductive element in the second position compared to the first position. The conductive element is configured to sense the target in the second position for any rotational position between the first member and the second member.

Surgical instruments with rotation stop devices and related methods are disclosed herein, e.g., for providing limited rotation between first and second components of the surgical instrument in a range greater than 360 degrees. Exemplary rotation stop devices can have a low profile and can include various features to facilitate packaging of the device within a larger instrument.

A surgical instrument includes a gripping assembly, a shaft assembly, an end effector, and a pivoting member. The gripping assembly defines a first opening for receiving a finger or a thumb of a user. The gripping assembly includes a first deformable feature that is configured to be moved in order to increase or decrease a cross-sectional area of the first opening. The shaft assembly extends distally from the gripping assembly. The end effector is positioned at a distal end of the shaft assembly and includes a first member. The pivoting member is pivotably coupled with the shaft assembly. The pivoting member is pivotable with respect to the first member of the end effector between an open position and a closed position to thereby clamp tissue between the first member and the pivoting member.

The present disclosure relates to surgical instruments and, more particularly, to a A surgical forceps is provided that is configured for treating and/or cutting tissue. The surgical forceps of the present invention is based on the so named ‘mosquito forceps’ and provides a new clamping configuration of the tip making it that is particularly useful for neuropathic skin surgery, such as in case of diabetes or other skin irregularities e.g. the callus or the like.
