METHODS FOR DELIVERING ENERGY INTO A TARGET TISSUE OF A BODY
An instrument and method for tissue thermotherapy including an inductive heating means to generate a vapor phase media that is used for interstitial, intraluminal, intracavity or topical tissue treatment. In one method, the vapor phase media is propagated from a probe outlet to provide a controlled vapor-to-liquid phase change in an interface with tissue to thereby apply ablative thermal energy delivery.
SURGICAL FORCEPS AND METHODS OF USE
Provided herein are systems, methods and apparatuses for surgical forceps for an easier and safer retrieval of foreign bodies in passages for better quality of care for patients.
Combined distraction and compression clamp for surgical operations
A dual compression and distraction tool for surgical operations, the tool including a first arm having a first pivot axis, a second pivot axis, a first lever, and a first dual purpose jaw, a second arm having a third pivot axis, a fourth pivot axis, a second lever, and a second dual purpose jaw, wherein, in a first position, the first arm is pivotably connected to the second arm such that the first pivot axis is merged with the third pivot axis, to form an distraction tool, and wherein, in a second position, the first arm is pivotably connected to the second arm such that the second pivot axis is merged with the fourth pivot axis, to form a compression tool.
A SURGICAL CLAMP FOR CLAMPING AN ORGAN
A surgical clamp for clamping an organ comprising: a first clamping member and a second clamping member each having a distal end and a proximal end; the first clamping member and second clamping member being connected to each other at their respective proximal ends and pivotally movable relative to each other between an open configuration and a closed configuration of the clamp; each of the first and second clamping members having one or more regions of curvature along its length; the first clamping member comprising a first tissue engaging portion having a first tissue engaging surface and the second clamping member comprising a second tissue engaging portion having a second tissue engaging surface; each of the first and second tissue engaging portions comprising an arrangement of teeth for engaging with the organ; wherein the first tissue engaging surface and the second tissue engaging surface are concave and oppose each other such that in the closed configuration, a gap is defined between the first and the second tissue engaging portions at an intermediate location along the respective first and second clamping members between their respective proximal and distal ends.
Microsurgical tool for robotic applications
The disclosed technology includes improved microsurgical tools providing multiple degrees of freedom at the wrist level, including roll, pitch, and grasp DOFs, a tight articulation bending radius, low radial offset, and improved stiffness. Some implementations include an end effector platform moveable along a fixed trajectory on a fictional axle so as not to interfere with a central-axis aligned working channel; a crossed-arm mechanical linkage for articulating an end-effector platform throughout a pitch DOF with an amplified pitch angle; and a partial pulley system to articulate the arms while maximizing pulley radius to shaft diameter, and permitting a constant transmission efficiency to the arms throughout the range of articulation. In some implementations, a tool shaft outer diameter may be smaller than 3 mm; a pitch DOF range may be 90, a roll DOF range may be 180, and a grasp DOF range may be 30.
Electrosurgical forceps for video assisted thoracoscopic surgery and other surgical procedures
A surgical instrument includes a shaft defining an axis, an end effector coupled to a distal portion thereof, a fixed handle coupled to a proximal portion thereof, a drive bar, a movable handle, and a linkage. The drive bar is disposed within the shaft and operably coupled to the end effector. The movable handle is movable relative to the fixed handle between open and closed positions and is coupled to the drive bar via a first pin on the axis. The linkage includes a first end portion coupled to the movable handle via a second pin and a second end portion coupled to the shaft via a third pin on the axis. In the closed position of the movable handle, the second pin is disposed in a near-over-center position relative to the axis to reduce a force necessary to maintain the movable handle in the closed position.
Combination medical device
A combination medical includes a first arm and a second arm interconnected to the first arm. The first arm and the second arm are biased towards each other by a closing force. A biasing member is disposed between the first arm and the second arm. The biasing member has a first position that biases the first arm and the second arm away from each other against the closing force and a second position that does not oppose the closing force. The combination medical device may be an electrosurgical device with a mono-polar and bi-polar configuration.
Electrosurgical device with disposable shaft having clamshell coupling
A surgical device for operating on tissue comprises an end effector, a disposable shaft assembly, and an interface assembly. The shaft assembly comprises an articulation section operable to provide deflection of the end effector relative to the longitudinal axis of the shaft. The interface assembly comprises a plurality of pivotable base sections. The interface assembly comprises a plurality of drive components associated with drive shafts driven by an external system and each drive component is associated with a section of the base. The drive components are operable to cause rotation of one or both of the shaft or end effector and movement of components of the end effector. The drive components are further operable to cause articulation of the articulation section. The base sections are pivotable toward each other to couple with the shaft assembly or away from each other to disengage the shaft assembly.

An instrument and method for tissue thermotherapy including an inductive heating means to generate a vapor phase media that is used for interstitial, intraluminal, intracavity or topical tissue treatment. In one method, the vapor phase media is propagated from a probe outlet to provide a controlled vapor-to-liquid phase change in an interface with tissue to thereby apply ablative thermal energy delivery.
Forceps drive shaft control
Surgical tool can include an outer shaft, a guide, an end effector, and a drive shaft. The outer shaft can extend along a longitudinal axis. The guide can be connected to the outer shaft. The end effector can include a first jaw connected to the outer shaft distal of the guide and a second jaw pivotably connected to the outer shaft distal of the guide. The drive shaft can be located within the outer shaft and can extend along the longitudinal axis. The drive shaft can be connected to the end effector and the drive shaft can be engageable with the guide to limit movement of the drive shaft with respect to the outer shaft in a direction not parallel with the guide. The drive shaft can be translatable along the outer shaft to operate the end effector.
