SURGICAL CLAMP
A surgical clamp including a pair of jaws, which may be used to ablate or create lesions in tissue. In an exemplary embodiment, the jaws are movable between an articulated position in which the jaws are separated and not parallel to one another, an opened position in which the jaws are separated and substantially parallel to one another, and a closed position in which the jaws are adjacent and substantially parallel to one another.
Modular battery powered handheld surgical instrument with motor drive
A surgical instrument includes a handle assembly; a shaft assembly and an end effector. The shaft assembly includes an exterior shaft, a first clutch positioned within the exterior shaft to drive a first function of the surgical instrument when engaged. A second clutch within the exterior shaft to drive a second function when engaged. A rotary driver is positioned within the exterior shaft and configured to rotate within the exterior shaft. The rotary driver includes a first clutch engagement mechanism to engage the first clutch and a second clutch engagement mechanism configured to engage the second clutch independent of the first clutch engagement mechanism engaging the first clutch, such that, at different times both the first clutch and the second clutch are engaged simultaneously only the first clutch is engaged only the second clutch is engaged and neither the first clutch nor the second clutch is engaged simultaneously.
Modular battery powered handheld surgical instrument with multiple magnetic position sensors
A system comprising a surgical instrument is disclosed. The surgical instrument includes a handle, a shaft, a plurality of magnets, a plurality of sensors configured to determine a distance away from one or more of the plurality of magnets, and a processor communicatively coupled to the plurality of sensors. The processor is configured to determine a three dimensional change in position of the shaft by computing a three dimensional change in position of the one or more magnets, using the change in the distances determined by the one or more plurality of sensors.
Matrix router for surgical ablation
A matrix router with frequency switching is provided having an energy source electrically connected to a plurality of interface ports. A switching device is provided between the energy source and the plurality of switches. One of the plurality of interface ports includes a paired electrode interface port for the connection of a paired electrode device thereto. The paired electrode device has a first pair of opposed electrodes and a second pair of opposed electrodes for clamping on tissue. When the paired electrode device is operably connected to the paired electrode interface port and actuated, the switching device alternates energy such as bipolar RF from the first pair of opposed electrodes to the second pair of opposed electrodes.
Surgical apparatus
A surgical apparatus includes a housing that supports a shaft assembly. The shaft assembly defines a longitudinal axis therethrough and includes coaxially aligned outer and inner shaft members. The inner shaft member is movable within the outer shaft member. An end effector includes a pair of jaw members disposed at a distal end of the outer shaft. At least one of the jaw members is pivotably coupled to the outer shaft and is movable between open and clamping configurations for grasping tissue. The inner shaft contacts a proximal end of the moveable jaw member to maintain the movable jaw member in the open configuration and is slidable against the movable jaw member to move the moveable jaw member between the open configuration and clamping configuration.
ENERGY TREATMENT TOOL AND TREATMENT SYSTEM
An energy treatment tool includes: a grip to be held by an operator; a lever that is provided in a state of being exposed to an outside of the grip, the lever being configured to move in response to a changing operation by an operator, the changing operation being for changing an output state of energy; an electric switch that is arranged inside the grip the electric switch being configured to generate a signal for changing an output state of the energy; and a driver that is installed inside the grip such that the driver is rotatable about an axis intersecting an axis along a longitudinal axis correspondingly to movement of the lever, the driver being configured to switch the electric switch between a contacting state and a noncontacting state.
SURGICAL TOOL
Disclosed is a surgical tool. The surgical tool comprises a surgical tool head (11) and a rod shaft (12). The surgical tool head (11) is connected with the shaft (12). The shaft (12) is a flexible shaft and comprises a flexible core and a flexible sleeve. The flexible sleeve has an inner cavity, and the flexible core is slidably disposed in the inner cavity. The surgical tool head (11) comprises two jaws (111, 112). The flexible core and the flexible sleeve are respectively connected with the two jaws (111, 112), and the flexible core is able to slide relatively to the flexible sleeve to drive the two jaws (111, 112) to make relative opening and closing movements. The shaft (12) of the surgical tool can be bent freely into any shape, and thus can be integrated into a flexible surgical tool and applied in a wider range.
Medical devices and methods incorporating frustrated total internal reflection for energy-efficient sealing and cutting of tissue using light energy
A medical instrument includes two jaw members, at least one of which creates conditions of frustrated total internal reflection at a tissue-contacting surface when tissue is grasped between the two jaw members. The first jaw member may include an optical element having a tissue-contacting surface. The medical instrument also includes a light source that provides a light beam for sealing tissue. The light source is positioned so that the light beam is totally internally reflected from an interface between the tissue-contacting surface and air when tissue is not grasped by the jaw members. When tissue is grasped by the jaw members, at least a portion of the light beam is transmitted through that portion of the tissue-contacting surface that is in contact with the tissue. The light source may be movably coupled to a jaw member to scan the light beam and/or to change the incident angle based on optical properties of the tissue.
Forceps motion transfer assemblies
Medical devices including a housing, an actuator, a body having a passageway extending through the body, a drive shaft extending through the passageway, and a clip coupled to the body and the drive shaft to fix the body relative to the drive shaft. The medical device further including features to couple the clip to at least one of the body and/or the drive shaft such that back out of the clip is inhibited.
ARTICULATION JOINT FEATURES FOR ARTICULATING SURGICAL DEVICE
An electrosurgical device comprises a body, an end effector, a cutting member, and a shaft. The end effector includes a pair of jaws that are operable to deliver RF energy to tissue that is clamped between the jaws. The cutting member is operable to sever tissue that is clamped between the jaws. The shaft extends between the body and the end effector. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. Some versions include a rotation section that is distal to the articulation section. The rotation section is operable to rotate the end effector relative to the articulation section.
