A handle assembly for use with a surgical tack applier includes an actuation assembly and an articulation lever assembly configured to articulate an articulation portion of the surgical tack applier. The actuation assembly includes a motor, an actuation rod, and an actuation switch configured to actuate the motor. The actuation rod has a first end operatively coupled to an output shaft of the motor for concomitant rotation therewith, and a second end operatively coupled to a loading unit of the surgical tack applier such that rotation of the actuation rod ejects a surgical tack from the loading unit. The articulation lever assembly includes an articulation rod operatively coupled with an articulation portion of the surgical tack applier such that axial displacement of the articulation rod causes articulation of the articulation portion, and an articulation lever operatively coupled with the articulation rod.

A surgical stapling device that includes an adapter assembly that has a flexible outer tube, and a tool assembly that is supported on the flexible outer tube having an anvil assembly and a shell assembly that supports an annular staple cartridge. The shell assembly includes a mechanism for approximating the anvil assembly with the shell assembly over two clamping stages to minimize forces transferred to the flexible outer tube of the adapter assembly during clamping. The shell assembly also includes a mechanism for minimizing firing forces required to eject staples from the staple cartridge.

A surgical system includes an end effector, a handle assembly that operates the end effector, and an adapter assembly that connects the end effector to the handle assembly. The adapter assembly includes an adapter housing, an outer tube, at least one gear assembly, and a worm gear assembly. The adapter housing has a proximal end portion connected to a distal end portion of the handle assembly. The outer tube extends distally from the adapter housing and supports the end effector on a distal end portion of the outer tube. The worm gear assembly is engaged with the at least one gear assembly and rotatable with the at least one gear assembly in the adapter housing to operate the end effector.

A powered surgical tack applier is configured to deploy a surgical tack through tissue or a surgical mesh. The surgical tack applier is articulatable to facilitate placement of the surgical tack to a desired surgical location. The powered surgical tack applier includes a power module that includes a battery, a motor, and a gear box. The power module provides a high-speed/low-toque output and a low-speed/high-torque output.

A surgical instrument module for powering a plurality of discrete surgical end effectors includes a motor, a planetary gear box, a high-torque/low-speed output operably coupled to the motor, and a high-speed/low-torque output operably coupled to the motor. The high-torque/low-speed output is configured to be operably coupled to a driven member of a first type of surgical end effector, and the high-speed/low-torque output is configured to drive an operation of a second type of surgical end effector.

Hand-held surgical instruments

A hand-held surgical instrument includes a handle housing, a shaft portion extending distally from the handle housing, and an articulation shaft. The articulation shaft may be configured to axially move within the shaft portion to articulate an end effector via a manual activation or a motor activation.

A surgical device includes a power source and a motor coupled to the power source. The device also includes a drive shaft having a proximal drive shaft having a proximal end portion coupled to the motor and a distal end portion, a proximal index gear coupled to the distal end portion of the proximal drive shaft, a distal drive shaft having a proximal end portion and a distal end portion, a distal index gear coupled to the proximal end portion of the distal drive shaft, a spring member biasedly coupling the proximal index gear and the distal index gear. The device also includes a force measurement sensor configured to measure rotation of the proximal index gear and the distal index gear. The device further includes a controller coupled to the force measurement sensor and configured to determine a force applied to the drive shaft based on a difference between rotation of the proximal index gear and the distal index gear.

A surgical device includes an end effector and a handle assembly operably coupled to the end effector. The end effector includes an anvil assembly and a cartridge assembly pivotally coupled to one another. The cartridge assembly includes a staple cartridge, a cartridge carrier, and a strain gauge. The cartridge carrier includes an elongated support channel configured to receive the staple cartridge, the elongated support channel defined by an inner first surface and a pair of inner second surfaces. The inner first surface includes a recess defined therein, and the strain gauge is disposed within the recess. The handle assembly includes a power-pack configured to receive sensor data from the strain gauge of the end effector and to control a function of the end effector in response to the sensor data.

Powered surgical devices including strain gauges incorporated into flex circuits

A surgical device includes a tool assembly and a handle assembly. The tool assembly includes a distal portion including a plurality of staples and an anvil assembly movable relative to the distal portion from an open position to a clamped position. The handle assembly includes an approximation mechanism coupled to the anvil assembly and configured to move the anvil assembly from the open position to the clamped position, a force sensor disposed at a distal end of the surgical device, and a controller. The force sensor is configured to sense a change in resistance indicating a force imparted on compressed tissue and on the approximation mechanism. The controller is configured to receive a signal indicative of a force measured by the force sensor and provide an indication of the sensed force.

The present disclosure provides an improved scale inhibiting formulation that is effective, environmentally friendly, and does not add any organic compounds or traditional polymeric compounds to treated water. The scale inhibiting composition includes molecular clusters of polyammonium bisulfate (PABS), which can interact physically, chemically, or physio-chemically with one or more ions in the water or water-containing system being treated. That interaction inhibits scale accretion and/or removes previously formed scale.

Method for controlling accretion of scale

Disclosed herein are clusters compounds that include at least one substituted amine sulfate and at least one substituted amine bisulfate molecule. The substituted amine sulfate molecule and the substituted amine bisulfate molecule may each include an ammonium moiety with at least one alkyl substituent. Optionally, the alkyl substituent can include 1 to 20 carbon atoms, 1 to 10 carbon atoms, or 1 to 6 carbon atoms. For example, the alkyl substituent can be a methyl, ethyl, propyl, butyl, or pentyl group. In some examples, the substituted amine sulfate molecule and the substituted amine bisulfate molecule each include an ammonium moiety with at least two alkyl substituents. Optionally, the two alkyl substituents are the same. Alternatively, however, the two alkyl substituents can be different.

Cluster compounds and methods of making the same

The present disclosure relates to a surgical device including an adapter assembly for selectively interconnecting an end effector and the device housing. The adapter assembly includes at least one drive converter assembly that converts and transmits a rotation of the rotatable drive shaft to an axial translation of at least one axially translatable drive member of the end effector. A first drive converter assembly includes a first drive element, a nut, an articulation sleeve, an articulation bearing, and an articulation link. Rotation of the rotatable drive shaft results in rotation of the first drive element. Rotation of the first drive element results in axial translation of the nut, the articulation sleeve, the articulation bearing, the articulation link, and the at least one axially translatable drive member of the end effector.

Described herein are methods of applying metals to substrates, where the methods include contacting the substrate with an aqueous metal plating composition comprising polyammonium bisulfate ('PABS') and a dissolved metal or salt thereof. The methods allow application of metals to the substrate without need for electrical energy input or for an added chemical catalyst, chelating agent, complexing agent, reducing agent, stabilizer, or pH-modifying (or controlling) chemical compound.
