摘要： Inserts and features to reduce or prevent spline crash in surgical staplers and/or to minimize damage resulting from spline crash in surgical staplers. An insert for a surgical stapler includes a body and spline covers. The body is configured to fit within a bore of a shell assembly and the spline covers extend inward from the body. Each of the spline covers are sized and dimensioned to cap a distal portion of splines of the shell assembly. A shell assembly for a surgical stapler includes shell splines that are disposed on an inner wall of an inner housing portion that defines a bore. The shell splines include a lead spline that has a leading end positioned distal of a leading end of each of the other shell splines.

摘要： A surgical device includes a handle assembly having a power source, a motor coupled to the power source, and a controller configured to control the motor. The device also includes an adapter assembly configured to selectively couple to the handle assembly, the adapter assembly including a stapling transmission assembly movable by the motor. The device also includes a reload configured to selectively couple to a distal portion of the adapter assembly, the reload including a plurality of staples ejectable from the reload by the stapling transmission assembly. The device also includes an anvil assembly selectively couplable to the distal portion of the adapter assembly, the anvil assembly being movable relative to the reload, where the controller may be further configured to control the motor to move the stapling transmission assembly to eject the staples while compensating for mechanical losses of the stapling transmission assembly.

摘要： According to one embodiment of the present disclosure, a surgical device is disclosed. The surgical device includes a motor and a transmission assembly movable by the motor. The surgical device also includes a force sensor configured to measure force imparted on the transmission assembly. The device may also include a controller configured to: control the motor to move the transmission assembly to a starting position, interrogate the force sensor to receive a sensor signal, compare the sensor signal to a threshold, and determine whether the force sensor is faulty based on the comparison of the sensor signal to the threshold.

摘要： A method of operating a surgical stapler includes advancing a knife assembly at a first velocity until a predetermined force is detected, advancing the knife assembly at a second velocity when the predetermined force is detected, the second velocity being less than the first velocity, and continuing to advance the knife assembly at the second velocity until the knife assembly travels a cutting stroke distance.

摘要： A surgical stapling device includes a tool assembly having an anvil assembly and a staple cartridge, the anvil assembly is movable in relation to the staple cartridge between spaced and clamped positions. The anvil assembly includes a housing defining a recess and a mesh material positioned within the recess. The staple cartridge includes a body defining a plurality of staple receiving slots. Each of the staple receiving slots supports a staple. The staple receiving slots are aligned with the recess when the anvil assembly and the staple cartridge are in the clamped position such that the plurality of staples are ejected and penetrate into the mesh material when the tool assembly is fired. Each of the plurality of staples includes a backspan and a leg extending from each end of the backspan. Each of the legs includes a locking structure that is configured to mesh or interlock with the mesh material of the anvil assembly upon penetration of the mesh material by the legs of the staples to obstruct withdrawal of the legs from the locking material.

摘要： A surgical stapling device includes an anvil assembly having a center rod and an anvil head that is pivotally coupled to the center rod. The anvil head supports a cut ring assembly that is movable between a pre-fired or retracted position in which the cut ring is positioned to retain the anvil head in an operative position and an advanced position in which the cut ring assembly is positioned to allow movement of the anvil head to a tilted position. The anvil assembly also includes at least one support member that is movable from a pre-fired position extending into the anvil head to an advanced position extending from the distal end of the anvil head to allow the cut ring assembly to move from the first position to the second position. The at least one support member can be returned to the pre-fired position after the stapling device is fired and the anvil head has tilted to reset the anvil head to the operative position
