Provided are a cartridge, and a treatment device for an endoscope comprising same. The present invention includes a straight guide path in which a clip connector and a moving tube separation bar are arranged in a straight line, and arranges a front moving tube, which is inserted in and arranged on the tip of a clip facing the moving tube separation bar and temporarily restrains a pair of forceps in a retracted state, and arranges a rear moving tube, which is assembled on the outer surface of the clip connector, so as to be slidably movable along the straight guide path toward the moving tube separation bar, wherein the clip is restrained in a retracted state inside an insertion tube entering internally along the straight guide path.

A method for downloading data from a surgical hub to a surgical instrument is disclosed. The method comprises assembling a first shaft assembly to a handle and downloading a first set of operational data from the surgical hub to the handle once the first shaft assembly is attached to the handle. The method further comprises assembling a second shaft assembly to the handle and downloading a second set of operational data from the surgical hub to the handle once the second shaft assembly is attached to the handle, wherein the second set of operational data is different than the first set of operational data.

A surgical instrument, such as an endoscopic or laparoscopic instrument. The surgical instrument may comprise an end effector comprising at least one sensor. The surgical instrument may also comprise an electrically conductive shaft having a distal end connected to the end effector wherein the sensor is electrically insulated from the shaft. The surgical instrument may also comprise a handle connected to a proximate end of the shaft. The handle may comprise a control unit electrically coupled to the shaft such that the shaft radiates signals as an antenna from the control unit to the sensor and receives radiated signals from the sensor. Other components electrically coupled to the shaft may also radiate the signals.

A medical device forming method, an applier for manipulating clips, and a cartridge for holding clips are disclosed herein.

A medical instrument has a capsule; an arm member disposed to protrude from the capsule; an operation wire connected to the arm member; a sheath configured to accommodate the operation wire; and a link configured to connect the sheath with the capsule, wherein the link has an engaging portion including a first surface intersecting with the longitudinal axis; and an engaged portion movable to an opposite position opposite to the first surface and a position spaced away from the first surface in spite of a relative position of the capsule with respect to the sheath, and configured to restrict a separation of the capsule with respect to the sheath when the engaged portion is disposed at the opposition position to contact the first surface, and wherein the capsule is rotatable in response to a rotation force from the sheath when the engaged portion is disposed at the opposition position.

A clip-cartridge assembly and a clip applicator are provided. The clip-cartridge assembly includes a clip-cartridge, a clip delivery device, and a clip jaw provided on a side of the clip-cartridge. The clip-cartridge includes an accommodation cavity for placing a ligation clip and the clip delivery device; the clip delivery device includes an elastic member and a clip pushing block for pushing the ligation clip within the accommodation cavity to move; and if the clip jaw is closed, the elastic member, by an elastic force of the elastic member, drives the clip pushing block to move in a movement direction toward the clip jaw.

A medical device includes a clip having an arm member and a pressing tube configured to receive the arm member; an applicator having an operation wire configured to advance and retract to open and close the arm member and a sheath configured to accommodate the operation wire; and a link configured to engage the operation wire with the clip and transition between an engagement configuration in which the clip and the operation wire is engaged with each other and a release configuration in which the engagement of the clip and the operation wire is released.

A ligation device includes a first arm, a second arm, a holding tube, an operation wire, a sheath, and a link mechanism having a first link and a second link which are connected to each other and engage the holding tube with the sheath, wherein the link mechanism is configured to be switch between a disengaged configuration in which engagement between the holding tube and the sheath is released and an engaged configuration in which the holding tube is engaged with the sheath due to the operation wire.

A surgical device for clipping tissue is disclosed. The surgical device comprises a clip magazine comprising a plurality of clips, an end effector movable between an open position and a closed position, and a jaw actuator operably responsive to a first rotatable input. The jaw actuator is configured to move the end effector between the open position and the closed position. The surgical device further comprises a reciprocating feeder drive and a controller. The reciprocating feeder drive is operably responsive to a second rotatable input. The controller is configured to advance a clip from the clip magazine into the end effector by way of the feeder drive when the end effector is in the open configuration. The controller is further configured to actuate the jaw actuator to move the first jaw and the second jaw toward the closed position without advancing a clip into the end effector.

A powered surgical instrument comprising an end effector, a sensor configured to output a signal, an elongate shaft, and a handle is disclosed. The end effector comprises a first jaw, a second jaw movable relative to the first jaw, a channel, a staple cartridge, an anvil, and a firing member configured to be driven during a firing stroke. The firing member experiences a pushing force during the firing stroke and comprises a knife portion, a first camming member configured to engage the first jaw, a second camming member configured to engage and position the second jaw. The handle comprises a motor, a battery, means for detecting the pushing force of the firing member, and a control unit configured to receive the signal from the sensor. The control unit includes a microprocessor which utilizes a pulse width modulation circuit to control the motor based on the signal received from the sensor.
