Energy-based surgical device and system facilitating tissue removal
An energy-based surgical device includes an elongated outer tube having a distal overhang, a proximal hub, a distal cutting member, and a flat spring. The distal cutting member has a U-shaped cutting edge and defines a mouth with the distal overhang extending therethrough. The flat spring includes a first portion extending distally along an exterior surface of the elongated outer tube and the distal overhang, a second portion extending from the first portion and bent over a free distal end of the distal overhang, and a third portion extending from the second portion proximally through the mouth of the distal cutting member and into the lumen of the elongated outer tube and traverses a majority of a diameter thereof. The distal cutting member and flat spring are adapted to connect to a source for electrosurgical energy for conducting bipolar energy through tissue disposed therebetween to cut tissue.
Gear assembly and surgical instrument with a gear assembly
A gear arrangement including two drive units (210, 220, 310, 320, 410), and two translatory transmission elements (151, 152, 251, 252, 351, 352), to each of which a rotationally movable function unit (141, 142) of a distally arranged two-part end effector (140) can be coupled. The first drive unit (210, 310, 410) has at least one proximally arranged rotation element (311, 411) or a thrust element (210) for opening or closing the end effector (140) by rotation of at least one function unit (141, 142). The second drive unit (220, 320), with which the translatory transmission elements (151, 152, 251, 252, 351, 352) are movable in opposite directions, has at least one proximally arranged rotation element (224, 320, 421) for simultaneous and unidirectional pivoting of the function units (141, 142) of the end effector (140). A surgical instrument includes the gear arrangement (200, 300, 400) in the handle (180).
SENSOR ENCAPSULATING ASSEMBLY
A system includes a wiring harness and an encapsulation assembly for encapsulating a connection region between electronic components of the wiring harness. The wiring harness includes a force sensor electrically coupled to a flex cable at a connection region. The encapsulation assembly includes a mold having a first and second mold halves configured to retain the force sensor therein and define a cavity above the connection region of the wiring harness.
Surgical instrument
A surgical instrument comprises a shaft, wherein a deflectable articulation section is formed at the shaft, a proximal handling portion at a proximal end of the shaft, a distal effector at a distal end of the shaft, and a deflection mechanism for controlling a bending state of the articulation section. The deflection mechanism comprises a first pull element for a deflection movement and a second pull element for a return movement. The first pull element and the second pull element are jointly pretensioned during the movement of the articulation section. An interface is provided where the instrument is demountable into a distal shaft assembly and a proximal handle piece, wherein the effector is controlled via an actuation mechanism that passes through the interface in a mounted state. The actuation mechanism comprises a push piece having a distal end that is coupled with the effector and a proximal end that is actuable by a pushing movement.
Surgical tissue fusion instrument
Surgical tissue fusion instrument having two gripping structures which are movable relative to each other, are designed for gripping and bringing together biological tissue sections, and are assigned heat-generating means designed in such a way that tissue fusion takes place between the biological tissue sections by heat being supplied in the area of the gripping structures. At least one gripping structure is assigned a fluid-conducting system, which is designed to supply at least one liquid or flowable additive to the tissue sections during a tissue fusion process.
Surgical clamping device with parallel closure
A surgical clamping device includes a handgrip, an actuation assembly, an elongated body portion, an upper jaw assembly, and a lower jaw assembly. Each of the upper and lower jaw assemblies includes and an elongated jaw body and a distal clamping portion that is supported on a distal end of a respective elongated jaw body. Each of the elongated jaw bodies includes a proximal end that is pivotally connected to the actuation assembly by a pivot member located within the handgrip. The pivot member is spaced from the distal clamping portions of the upper and lower jaw assemblies such that the distal clamping portions of the upper and lower jaw assemblies remain substantially parallel as the upper and lower jaw assemblies are pivoted between open and clamped positions.
Orthopedic Clamps
An orthopedic clamp to assist in reducing the displacement between bone ends of a fracture, and to position a fixation device, during open fracture reduction surgery is described. The clamp includes a holder to hold the fixation device against the bone. The clamp may also swivel in relation to the holder while the position of the fixation device remains unchanged.
SURGICAL INSTRUMENT
A surgical instrument according to one or more embodiments may include: a base; an end effector; an elongated element to drive the end effector; a flexible shaft including a distal end coupled with the end effector; a winding member provided to the base rotatably about a rotational axis orthogonal to the second surface such that the elongated element from the flexible shaft is wound around the winding member; a drive receiving member rotatable about a rotational axis orthogonal to the second surface, to receive drive for rotating the winding member; a first guide pulley; and a second guide pulley. The first guide pulley guides the elongated element drawn from the shaft toward the second guide pulley along the rotational axis of the winding member, and the second guide pulley guides the elongated element from the first guide pulley toward the winding member in a direction intersecting the rotational axis.
SURGICAL CLAMP
Surgical devices and related methods are disclosed. An example end effector for a surgical device may include a first jaw, a second jaw, and an articulating mechanism operable to move the first jaw between an open position, an intermediate position, and a closed position. An example articulating mechanism may include a first jaw mount coupled to the first jaw so that movement of the first jaw mount along a path causes rotation and translation of the first jaw mount and the first jaw. A pivotably mounted crank may operably couple an actuator linkage to the first jaw mount so that moving the actuator linkage rotates the crank, and rotation of the crank may move the first jaw mount along the path.
CERVICAL TENACULUM DEVICE
A surgical device comprising a shaft comprised of a first end and a second end; a clamp configured to be locked or unlocked attached to the first end of the shaft; an actuator shaft that is removably coupled to the shaft and configured to open and close the clamp; and optionally an anchor.
