Abstract: A surgical stapler includes a first elongate member having a distal portion that supports a plurality of staple-forming pockets, a second elongate member having a distal portion that supports a staple cartridge, and a clamp member movable from an open position to a closed position to releasably clamp the first and second elongate members together. A clamp lockout feature is supported by the first elongate member and is moveable between a lockout position in which the clamp lockout feature prevents closure of the clamp member, and a release position in which the clamp lockout feature permits closure of the clamp member. An actuating feature is supported by the second elongate member and is configured to actuate the clamp lockout feature from the lockout position to the release position in response to approximation of the distal portions of the first and second elongate members.

Each of the first and second contact members includes proximal and distal portions and an extension formed on the proximal portions. Each of the first and second elongated electrical conductors includes proximal and distal portions and a loop formed on the distal portion. The loop of each of the first and second elongated electrical conductors is received about the extension of the respective first and second contact members.

Abstract: A surgical instrument includes a body, a shaft assembly, a stapling head assembly, an anvil, an anvil adjustment assembly, a trigger, and a lockout assembly. The stapling head assembly is operable to drive an annular array of staples. The anvil is configured to couple with the stapling head assembly. The anvil adjustment assembly includes a translating member, which translates relative to the body to thereby adjust the longitudinal position of the anvil relative to the stapling head assembly. The trigger is operable to actuate the stapling head assembly to thereby drive the annular array of staples through a distal surface of the stapling head assembly toward the anvil. The lockout assembly includes an electrically powered braking feature. In a first state, the lockout assembly is configured to permit translation of the translating member. In a second state, the lockout assembly is configured to prevent translation of the translating member.

Abstract: A surgical stapler includes an anvil half having an anvil channel member and a cartridge half having a cartridge channel member. A latching lever is coupled to the cartridge channel member and is pivotable between a closed position in which the lever fixes the anvil channel member relative to the cartridge channel member, and an open position in which the lever permits relative movement between the channel members. A locking member coupled to a proximal portion of the cartridge half is movable between a locked position when the lever is in the closed position and an unlocked position when the lever is in the open position. In the locked position the locking member captures the projection and locks the anvil half proximal portion to the cartridge half proximal portion. In the unlocked position the locking member releases the projection and permits separation of the proximal portions.

Abstract: It is an object of the invention to provide a power tool capable of performing a control process for avoiding an operation of a protection function for protecting a motor against an overload, unlike the conventional power tool. The control unit detects current I flowing in the motor and determines whether current I exceeds I1 or not (S2). When current I exceeds I1 (S2: Yes), the control unit starts a duty ratio adjustment mode. When current I exceeds Imax (S4: Yes), the control unit accords a protection priority over the adjustment of the duty ratio and stops supplying power to the motor (S5). If current I does not exceed Imax (S4: No), the duty ratio is decreased (S7). When current I becomes lower than I2 (S8: Yes), the control unit increases the duty ratio (S10).

Abstract: A wound package construct includes a first wound strip of package material that establishes an inner liner layer, a second wound strip of material that establishes an intermediate bodystock layer, and a third wound strip of material or cover strip that covers a seam formed by the wound bodystock layer but that does not cover all of the outer surface area of the wound bodystock layer. Therefore, the width of the cover strip is less than the width of the bodystock strip. As a result, the cover strip is not wide enough to cover the entire outer surface of the wound bodystock layer such that, after the cover strip is wrapped to cover the spiral bodystock seam, areas of the bodystock layer remain exposed between the two opposed length-wise edges of the cover strip.

Abstract: A power tool includes a housing, an auxiliary handle, and a vibration damping assembly. The auxiliary handle includes a front end and a gripping portion. The vibration damping assembly includes a mass member and an elastic element. The auxiliary handle further includes an end cap arranged at a rear end of the gripping portion where the rear end is far away from the housing relative to a front end of the gripping portion. An accommodating cavity for accommodating the vibration damping assembly is formed around the gripping portion. The elastic element is arranged between a mass member and a cavity wall of the accommodating cavity. A ratio of a natural frequency W1 of the vibration damping assembly to a rotation frequency W2 of an output shaft in rotation is greater than or equal to 0.7 and less than or equal to 1.3.

Abstract: An adjunct material for use with an end effector in a surgical instrument is provided that has at least one projection configured to mate with a corresponding recess formed in at least one jaw, such as a cartridge or anvil, of the end effector. The at least one projection can be one or more discrete projections or longitudinal projection(s) extending between distal and proximal ends of the adjunct material. An applicator member can be used to apply force to the adjunct material to thus cause the adjunct material to mate with the jaw of the end effector. The applicator member can be configured told the adjunct material and can be clamped between the jaws of the end effector to release the adjunct material onto the jaw. Also, an applicator member can be used to push portions of an adjunct material into corresponding recesses in a jaw.

Abstract: In the method for transferring at least one item to be packaged into a container and for transporting the filled container onward, the container is arranged in a transfer area, which is arranged next to a linear motor transport device. The at least one item to be packaged is conveyed in a conveying direction to a transfer position by the linear motor transport device. After that, the at least one item to be packaged is moved from the transfer position to the transfer area, where the container is filled with the at least one item to be packaged.

Abstract: A hand-held machine tool for a striking tool has a motor, an impact mechanism, a spool valve, and a pneumatic chamber. The impact mechanism has an exciter piston moved by the motor, and a hammer coupled to the exciter piston via a pneumatic chamber between the exciter piston and the hammer, and a striker in front of the hammer in the striking direction. In a working position counter to the striking direction, the striker bears on a stop, in a starting position the striker is offset in the striking direction relative to the working position, and in a rest position the striker is offset in the striking direction relative to the starting position. In the starting position, the hammer bearing on the striker closes the spool valve and, in the rest position, the hammer bearing on the striker opens the spool valve.

Abstract: A gas spring fastener driving tool, having a cylinder filled with compressed gas that forces a piston/driver through a driving stroke movement; a rotary-to-linear lifter, then moves the piston/driver back to its ready position, preparing the tool for another driving stroke. The driver has protrusions (teeth) along its edges to contact extending pins of the lifter member, for lifting the driver during a return stroke. The driver's movements are detected by position sensors, and the information provided by those position sensors is used to prevent the lifter from impacting against the driver in situations where the driver did not finish its driving stroke in a correct (“in specification”) position. The use of two position sensors allows a Dry Fire diagnostic test to determine if gas pressure in the gas storage chamber is too high, or has become too low.
