Abstract:
A surgical tool for minimally invasive surgery. The surgical tool in one embodiment includes a manipulator as a user interface, a proximal universal joint mounted to the manipulator, a hollow elongated member such as a tube mounted to the proximal universal joint, and a distal universal joint mounted to the other end of the elongated member. An end effector is mounted to the distal universal joint second end. Pivoting of the first end of the proximal universal joint causes the second end of the distal universal joint to move in a corresponding motion, and cabling operatively couples the proximal and distal universal joints. The proximal and distal universal joints may each include two yokes and a center block. Cabling may include four cables that each engage two round elements at the proximal and distal universal joints mounting locations to the center block.
Abstract:
A surgical instrument includes a handle assembly housing a wireless circuit board. The wireless circuit board transmits a signal to a set of safety glasses worn by a surgeon using the surgical instrument during a procedure. The signal is received by a wireless port on the safety glasses. One or more lighting devices on a front lens of the safety glasses change color, fade, or glow in response to the received signal to indicate information to the surgeon about the status of the surgical instrument. The lighting devices are disposable on peripheral edges of the front lens to not distract the direct line of vision of the surgeon.
Abstract:
The invention relates to a reduction forceps comprising a first rod and a second rod, which are supported on a swivel joint defining an axis of rotation such that they are pivotable relative to one another, the first rod comprising on one side of the swivel joint a first jaw and the second rod comprising, on the same side of the swivel joint, a second jaw provided for cooperation with the first jaw, both said jaws having defined thereon contact points for contacting a bone or a bone plate, said contact points being movable in a common pivoting plane, which comprises the swivel joint and in which the axis of rotation extends perpendicularly, and at least one of the jaws being sectionwise displaced in the direction of a plane extending parallel to the pivoting plane.
Abstract:
A surgical instrument may include a reusable body assembly, a reusable transducer and blade assembly, and a disposable end effector. The transducer and blade assembly may be latched into the body assembly. One version may include an electrical connector on the latch member to electrically couple the body assembly to the transducer. The end effector may include an outer sheath portion coupleable to an outer sheath of the body assembly via a bayonet connection and a clamp arm pivotably coupled to the outer sheath portion. In some versions, an inner tubular member of the body assembly may also couple to an inner tube portion via a bayonet connection. The inner tubular member may include a key to align with a slot on the transducer and blade assembly to align the clamp arm with the blade. The end effector may alternatively couple via threading or ratcheting teeth having a slip feature.
Abstract:
The invention relates to a medical instrument for removing tissue, in particular a shaver, drill, or morcellator, having a tool that can be set in rotation and a motorized drive for driving the tool, and having an elongate body and a handle that projects laterally from said elongate body. The handle is fastened in a detachable manner to the body.
Abstract:
Instrument handles are adjustable relative to an end effector of the instrument. The handles may be releasably locked in selected positions and/or orientations relative to the end effector. When the lock is released, the handles may be moved to a different position and/or orientation relative to the end effector, and locked in place. The handles may pivot relative to the end effector around one or more joints. The handles may pivot about an axis of a hinge joint or a point of a ball and socket joint. The axis of the hinge joint may be aligned parallel or perpendicular to a center longitudinal axis of the end effector, or of a shaft between the handles and the end effector.
Abstract:
A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened.
Abstract:
The present disclosure relates to hand held electromechanical powered surgical handle assemblies for use with surgical end effectors capable of clamping, cutting and/or stapling tissue and methods of use thereof. The surgical device includes a handle assembly and a drive unit assembly removably and selectively connectable to a selected first connecting feature and second connecting feature of the handle assembly. The drive unit assembly includes a motor and a drive shaft driven by the motor.
Abstract:
A surgical fastener system can comprise a plurality of fasteners which can be connected to each other by, one, a retention matrix which is assembled to the fasteners in order to capture tissue within the fasteners and, two, an alignment matrix configured to hold the fasteners together before the retention matrix is assembled thereto. In various embodiments, the retention matrix and the alignment matrix can each comprise a tissue-contacting surface configured to compress tissue therebetween.
Abstract:
A medical instrument with an elongate shank which, at a distal end, carries a spatula, and, in a proximal end area, has a shank head on which a laterally protruding handle is arranged. The shank is rotatable relative to the handle about a rotation axis parallel to a longitudinal axis of the shank.
