A method for adjusting the operation of a surgical suturing instrument using machine learning in a surgical suite is disclosed. The method comprises gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical suturing instrument comprising a suturing needle configured to be mechanically advanced through a suturing stroke, analyzing the gathered data to determine an appropriate operational adjustment of the surgical suturing instrument, and adjusting the operation of the surgical suturing instrument to improve the operation of the surgical suturing instrument.

A treatment device for treating a target tissue includes a drive source having a transducer configured to convert electrical energy to mechanical vibrations, an instrument having a blade connected to the drive source and configured to apply the mechanical vibrations to the target tissue, and a control unit configured to control a supply of electrical energy to the drive source. The control unit is configured to automatically adjust the supply of electrical energy to the drive source in response to a detection of a change in a resonance frequency of the blade. The change in resonance frequency of the blade occurs after the target tissue has been completely cut by the blade.

An ultrasonic instrument includes a body, a shaft assembly, and an end effector. The shaft assembly extends distally from the body. The shaft assembly includes an acoustic waveguide configured to acoustically couple with an ultrasonic transducer. The end effector includes an ultrasonic blade, a clamp arm and a clamp pad. The ultrasonic blade is in acoustic communication with the waveguide. The clamp arm is pivotally coupled with the shaft assembly. The clamp pad is configured to removably couple with the clamp arm while the clamp arm is pivotally coupled to the shaft assembly.

A vibration transmission member includes a main body, a treatment portion that is provided at the distal end of the main body, a first covering formed of a material that has an electrical insulating property and has a thermal conductivity lower than a thermal conductivity of the main body, which covers a part of a surface of the treatment portion, and a second covering formed of a material that has an electrical insulating property and has a thermal conductivity lower than the thermal conductivity of the main body. The second covering is integrally formed with at least a part of the first covering and varies in thickness in a circumferential direction of the main body. The second covering includes a first area and a second area in the circumferential direction, such that a thickness dimension of the first area is smaller than a thickness dimension of the second area.

A treatment tool includes a first grasper and a second grasper. The first grasper includes a treatment portion that includes a treatment surface and an opposing surface, and a holder portion that is mounted on the opposing surface. The holder portion is formed of an elastically deformable material, and includes a first region having a first contact surface, a second region having a second contact surface, and a connection region that is arranged between the first contact surface and the second contact surface and that includes a concave portion. The holder portion is mounted on the opposing surface in an elastically deformed state such that the first contact surface and the second contact surface are in contact with the opposing surface and such that a depth of the concave portion is smaller than a depth of the concave portion is a non-elastically deformed state.

An end effector assembly of a forceps includes a first jaw with a tissue sealing surface and an electrode on the sealing surface, and a second jaw with a tissue sealing surface and an electrode on the sealing surface. The first jaw and the second jaw move between an open position and a closed position. The sealing surface of at least one of the first jaw and the second jaw has a rigid medial section and flexible lateral sections.

A surgical instrument includes a housing, an end effector, a movable handle, and a drive assembly. The movable handle includes first and second cantilever spring arms and is movable relative to the housing between a spaced-apart position and an approximated position. The first cantilever spring arm is flexed upon movement of the movable handle from the spaced-apart position towards the approximated position to bias the movable handle towards the spaced-apart position. The drive assembly is operably coupled between the movable handle and the end effector such that movement of the movable handle from the spaced-apart position towards the approximated position moves the end effector from an open position towards a clamping position for clamping tissue. The second cantilever spring arm is flexed upon application of a threshold pressure to tissue clamped by the end effector to control an amount of pressure applied to tissue clamped by the end effector.

A surgical instrument includes an end effector assembly including first and second grasping components each defining a tissue-contacting portion. One or both of the first or second grasping components is movable relative to the other between an open position and a closed position. In the closed position, the first and second tissue-contacting portions cooperate to define a grasping area therebetween. One or both of the first or second grasping components is configured to apply energy from the tissue-contacting portion thereof to tissue disposed within the grasping area to treat tissue. The tissue-contacting portion of the first grasping component defines a first opening therethrough. The first opening is disposed within the grasping area and in communication with a first lumen defined at least partially through the first grasping component. The first lumen is adapted to connect to a source of vacuum to enable aspiration through the first opening.

A jaw member for use with a surgical instrument includes a support base, a jaw liner, and a jaw overmold. The support base has a proximal portion configured to be pivotably coupled to a surgical instrument, and a distal portion. The support base defines a channel that extends longitudinally between the proximal and distal portions and an aperture disposed in communication with the channel. The jaw liner includes an elongate body configured for receipt in the channel of the support base, and a projection extending from the elongate body and configured for receipt in the aperture of the support base. The jaw overmold overlaps at least a portion of the support base and the jaw liner to fix the jaw liner to the support base.

Devices, systems and methods are provided for stabilizing and grasping tissues such as valve leaflets, assessing the grasp of these tissues, approximating and fixating the tissues, and assessing the fixation of the tissues to treat cardiac valve regurgitation, particularly mitral valve regurgitation.
