SHAFT RETENTION FEATURES FOR SHAFT-BASED SURGICAL INSTRUMENTS
A surgical instrument includes a housing, a shaft having a proximal end portion disposed within the housing, and an end effector assembly supported at a distal end portion of the shaft distally-spaced from the housing. A bobbin includes a body, a proximal rim, and a distal cylinder. The bobbin is disposed about the shaft such that at least one protrusion of the shaft is captured within a track defined within the distal cylinder. The bobbin is configured for positioning within the housing such that the body extends through a shaft aperture of a partition of the housing with the proximal rim disposed on a proximal side of the partition and the distal cylinder disposed within an interior cavity defined between the partition and a distal end of the housing on a distal side of the partition, thereby rotatably supporting the proximal end portion of the shaft within the housing.
ULTRASOUND TREATMENT TOOL
An ultrasound treatment tool includes a handle 6, a vibration transmitting member 13 that is formed in an elongated shape, the vibration transmitting member being configured to transmit an ultrasound vibration generated by a vibration generation source, a holder 112 configured to hold the vibration transmitting portion 13, and a rotary knob 9 configured to rotate about a longitudinal axis Ax1 of the vibration transmitting portion 13 in accordance with a user operation. The holder 112 and the rotary knob 9 are integrally coupled with each other, and are positioned respectively in a radial direction about the longitudinal axis Ax1 with respect to the handle 6. One of the holder 112 and the rotary knob 9 is positioned in a direction along the longitudinal axis Ax1 with respect to the handle 6.
Staple instrument comprising a firing path display
A surgical stapling system for stapling the tissue of a patient is disclosed. The stapling system comprises a housing, a shaft extending from the housing, and an end effector extending from the shaft. The end effector comprises a plurality of staples removably stored therein and, also, an anvil configured to deform the staples. The stapling system further comprises a firing mechanism configured to deploy the staples along a staple firing path longer than 60 mm, a camera configured to capture an image of the patient tissue, a display, and a controller configured to generate an image of the staple firing path, wherein the images are displayed on the display.
Surgical instrument including different length camming members
A surgical instrument comprising a surgical end effector that comprises a first jaw and a second jaw that is movably supported relative to the first jaw for selective movement between an open position and closed positions. The surgical instrument further comprises a closure member that is axially movable in response to closing and opening motions. The closure member comprises at least one opening cam that protrudes therefrom to movably engage a corresponding cam surface on the second jaw such that upon application of the opening motion, the at least one opening cam movably engages the corresponding cam surface to move the second jaw to an open position, even when the jaws are under a load.
Surgical treatment instrument
A surgical treatment instrument includes an elongated member an end effector that is bendable with respect to the elongated member, a bending operator operable to bend the end effector, a rotor rotatable about a rotation axis in response to operation of the bending operator, and a transmitter that transmits a driving force to bend the end effector. The bending operator, the rotor, and the transmitter are rotatable about the longitudinal axis together with the elongated member and the end effector.
Surgical instruments, control assemblies, and surgical systems facilitating manipulation and visualization
A surgical instrument includes a housing, a shaft extending from the housing, an end effector assembly extending from the shaft and configured to rotate and/or articulate relative to the housing, a motor disposed within the housing and operably coupled to the end effector assembly to rotate and/or articulate of the end effector assembly relative to the housing, and a sensing assembly configured to sense movement of the housing relative to a reference position and to drive the motor to rotate and/or articulate of the end effector assembly relative to the housing based upon the sensed movement. The sensing assembly is configured to operate in each of a standard mode, wherein movement of the housing effects rotation and/or articulation of the end effector assembly in a similar direction, and a reversed mode, wherein movement of the housing effects rotation and/or articulation of the end effector assembly in an opposite direction.
Electrosurgical instruments with electrodes having variable energy densities
An electrosurgical instrument comprising an end effector is disclosed. The end effector comprises a first jaw and a second jaw. At least one of the first jaw and the second jaw is movable to transition the end effector from an open configuration to a closed configuration to grasp tissue therebetween. The second jaw comprises linear portions cooperating to form an angular profile and a treatment surface comprising segments extending along the angular profile. The segments comprise different geometries and different conductivities. The segments are configured to produce variable energy densities along the treatment surface.
Wireless force sensor on a distal portion of a surgical instrument and method
A surgical instrument includes a distal portion. A force sensor is operatively mounted on the distal portion. The force sensor includes a wireless package, which wirelessly provides (1) identification information of the surgical instrument and (2) strain data related to the distal portion. A surgical end effector includes a jaw and the distal portion is on a non-contact portion of the jaw. The wireless package includes a surface acoustic wave strain sensor with identification information. The wireless package also includes a small folded antenna electrically coupled to the surface acoustic wave strain sensor with identification information. The identification information includes an identification of a type of surgical instrument and unique identification of the specific surgical instrument in the type of surgical instrument.
Treatment instrument
A treatment instrument includes a rotating body and a housing. The rotating body includes a connecting portion including: a supported portion having a cylindrical outer peripheral surface, and an engaged portion that is adjacent to the supported surface. The housing includes a supporting portion that is configured to support the supported portion of the rotating body, the supporting portion being rotatable around a predetermined rotation axis; and an engaging portion that is configured to generate a frictional force larger than a frictional force between the supporting portion and the supported portion by coming into contact with the engaged portion.
Contactless circuitry for corded surgical devices
A surgical device (10) includes a handle (122) and a rotatable assembly (130) coupled and rotatable with respect to the handle (122). The surgical device (10) further includes a switch (126) coupled to the handle (122) and having a plurality of positions. A first inductor (1122) is coupled to the switch (126) and a second inductor (1102) is coupled to the rotatable assembly (130). A current signal propagating through the first inductor (1122) and/or a current signal propagating through the second inductor (1102) changes based on a position of the switch (126).
