The present disclosure includes apparatuses for a surgical handle assembly. An example apparatus includes a reloadable cartridge assembly and a surgical handle assembly including an articulation assembly configured to maintain the reloadable cartridge assembly in a first operation position, the articulation assembly comprising a knob in a first position, a lock core coupled to the knob, a housing, a first roller and a second roller, and a first spring, wherein the first roller is positioned on a first end of the first spring and the second roller is positioned on a second end of the first spring, and wherein the first spring is configured to bias the first roller and the second roller between the lock core and the housing to maintain the knob in the first position.

The present invention aims to provide a staple reinforcement for a surgical stapler that can be used in surgical staplers of various sizes, is easily passed through ports, and is less likely to shift during operation of the surgical stapler. Provided is a staple reinforcement for a surgical stapler, including a fabric layer containing a bioabsorbable material and a sponge layer containing a water-soluble polymer, the fabric layer and the sponge layer being integrally laminated.

A surgical stapling device includes a tool assembly that includes an anvil assembly and a cartridge assembly. The cartridge assembly includes a channel member that includes structure for releasably engaging the anvil assembly to allow for separation of the entire cartridge assembly from the anvil assembly after each use of the stapling device.

Apparatus and methods are provided for performing a medical procedure, such as a laparoscopic appendectomy using a stapler apparatus including a reusable handle portion including a shaft include proximal and distal ends, a disposable end effector attached to the distal end of the shaft of the reusable handle carrying one or more staples. For example, the end effector may include first and second jaws movable relative to one another between open and closed positions, the first jaw carrying a cartridge which includes the one or more staples. A Doppler sensor, a cutting element, and, optionally, a thermal element are also provided on the end effector. The end effector is introduced into a patient's body, tissue is positioned/locked between the jaws, and a plurality of staples are deployed into the tissue. The Doppler sensor is used to confirm that blood flow has discontinued in the stapled tissue, and the cutting element is actuated to sever the stapled tissue.

A surgical instrument, such as a surgical fastener applying apparatus, includes a tool assembly, an endoscopic body portion, and an articulation mechanism. The articulation mechanism articulates the tool assembly in relation to the endoscopic body portion over large arc segments while providing simple operating components. Thus, the range of operation of the surgical instrument and the types of surgical activities that can be performed by the surgeon can be expanded without at the same time requiring complex operating components.

A surgical cutting and fastening instrument. The instrument comprises a handle and an end effector connected to the handle. The end effector comprises upper and lower opposing jaw members, wherein the upper jaw member comprises a plurality of co-linear, separately actuatable, RF electrodes.

According to one embodiment, an apparatus comprising a portable monitoring device to be affixed to a user. The portable monitoring device including: 1) a set of one or more sensors to generate sensor data indicative of physical activity of a user when the portable monitoring device is affixed to the user; and 2) processing circuitry coupled with the set of sensors, to detect that the user has been sedentary for a period of time, and cause the portable monitoring device to alert the user responsive to the detection to encourage the user to move.
