A surgical tool for use with a robotic system that includes a tool drive assembly that is operatively coupled to a control unit of the robotic system that is operable by inputs from an operator and is configured to robotically-generate output motions. A drive system is configured to interface with a corresponding portion of the tool drive assembly for receiving the robotically-generated output motions and applying the output motions to a drive shaft assembly which is configured to apply control motions to a surgical end effector operably coupled thereto. A manually-actuatable control system operably interfaces with the drive shaft assembly to facilitate the selective application of manually-generated control motions to the drive shaft assembly.

In various embodiments, a surgical fastening apparatus comprising a motorized drive system and an end effector is disclosed. The end effector comprises a channel and a rotary drive shaft. The channel is configured to support a removable staple cartridge including staples that are ejected from the removable staple cartridge as an ejector therein is moved from a starting position to an ending position. The rotary drive shaft defines an axis and is supported by the channel for movement in directions transverse to the axis between an engaged position wherein the rotary drive shaft is rotatable by the motorized drive system and a disengaged position wherein said rotary drive shaft is not rotatable by the motorized drive system. The rotary end effector drive shaft is retained in the disengaged position unless the removable staple cartridge has been operably installed within the channel and the ejector is in the starting position.

A medical connector can include a body having a fluid path with an inlet port, an outlet port, a luer portion, and a post extending through a fluid path. An arm having a latch member is coupled to the body to engage a ridge or thread on an exterior surface of a reciprocal connector. The arm may also include an extension. When the connector is in an open position, the latch member restricts retraction of the reciprocal connector from the outlet port. A seal is coupled to the body and includes a flap extending across the outlet port or a bellows to compress along an axis. In a closed position, the post restricts flow through the luer portion. In an open position, the post permits flow through the luer portion.

A molded spike port including a first portion defining a first chamber, a plug disposed in the first chamber and configured to form a seal with the first portion, a second portion defining a second chamber, the second portion including a sealing ring configured to seal the spike port to a spike, a tip configured to be inserted into a fluid bag, the tip comprising a membrane, and a wall between the first portion and the second portion, wherein the wall is configured to break when the first portion is twisted relative to the second portion.

A closed male luer includes a first connector having an upper end portion defining an axial recess, an inner circumferential slide track and several first ratchet teeth; and a second connector having lower end portion received in the axial recess of the first connector, having several second ratchet teeth selectively meshed with the first ratchet teeth such that rotation of the first connector in a first direction drives the second connector to rotate simultaneously in the first direction, wherein, after an upper end portion of the second connector is connected with a second member, rotation of the first connector in the first direction or rotation of the second connector in a second direction opposite to the first direction can break up the second ratchet teeth into pieces by the first ratchet teeth, hence permitting the second connector to rotate freely in 360 relative to the first connector.

A frangible connector has a first side that forms a female luer when a second side is fractured at a predefined break line. The second side may be connected to a fluid circuit, for example, a source of medical treatment fluid such as dialysate.

A rotary drive arrangement for a surgical instrument that includes a surgical end effector. In one form, the rotary drive arrangement includes a drive shaft assembly that is selectively axially movable between a first position and a second position. A rotary transmission operably interfaces with the drive shaft assembly such that when the drive shaft assembly is in the first axial position, application of one of the rotary drive motions to the drive shaft assembly causes the rotary transmission to apply a first rotary control motion to the surgical end effector and when the drive shaft assembly is in the second axial position, application of the rotary drive motion to the drive shaft assembly causes the rotary transmission to apply a second rotary control motion to the surgical end effector.
