In accordance with an exemplary embodiment, a surgical instrument comprises a shaft and an actuation member extending through a bore of the shaft and operably coupled to an end effector. A sleeve is disposed around the actuation member and within the bore of the shaft. A flux conduit configured to transmit a surgical flux to the end effector is at least partially received within a negative feature of the sleeve. In accordance with another exemplary embodiment, a surgical instrument comprises a shaft, a wrist mechanism coupling an end effector to the shaft, and an actuation member operably coupled to the end effector. A sleeve surrounds the actuation member and has a straight passage. A flux conduit operably coupled to the end effector is received within the straight passage. A portion of the flux conduit is slack in a region of the shaft through which the sleeve does not extend.

Routing mechanisms for surgical instruments, and related devices, systems, and methods

A sheath for a surgical instrument may include a sleeve having a distal end and proximal end, and a retention mechanism at a proximal end portion of the sleeve. The retention mechanism may comprise a sleeve attachment portion configured to be attached to the sleeve at the proximal end portion, and a locking collar extending from the sleeve attachment portion, wherein the locking collar is configured to receive a connector portion of a surgical instrument. The locking collar further may include a locking feature movable between a first configuration, in which the sheath is moveable relative to the surgical instrument, and a second configuration, in which the locking feature is configured to engage with the connector portion to retain the sheath in position on the surgical instrument.

Sheathes for surgical instruments, and related devices and methods

A surgical instrument includes a reusable instrument portion and a disposable tip assembly. The disposable tip assembly includes an end effector assembly that in turn includes an end effector. The disposable tip assembly also includes a locking tip cover that locks the disposable tip assembly to a lock interface element of a tip interface of the reusable instrument portion. To facilitate mounting the disposable tip assembly on the tip interface of the reusable instrument portion, the disposable tip assembly includes a first quick connect/disconnect element and the tip interface includes a second quick connect/disconnect element. The second quick connect/disconnect element is coupled to a tendon. The tendon is also coupled to an actuator assembly that provides forces that push and pull (push/pull) the tendon.

Reusable surgical instrument with single-use tip and integrated tip cover

A cannula seal is presented. The cannula seal includes a cross-slit seal that can include a side wall that includes folded sidewalls; slits that are formed by the folded sidewalls when the cross-slit seal is in a closed position; and a concave end surface at the slits. The cross-slit seal can include energizing ribs formed to close the seal. The instrument guide includes a pyramidal shaped seal that seals against doors when no instrument is inserted and seals against an instrument when the instrument is inserted.

Sealing multiple surgical instruments

In accordance with at least one exemplary embodiment, a surgical instrument comprises a shaft comprising a distal end, a proximal end, and a wall extending from the distal end to the proximal end, the wall surrounding an interior of the shaft. A transmission housing is located at the proximal end of the shaft and the shaft is rotatably coupled to the transmission housing. An actuator in the transmission housing is operably coupled to actuate rotation of the shaft. A port accessible from an exterior of the transmission housing is configured to be fluidically coupled to a fluid supply. A manifold in the transmission housing comprises an inlet and an outlet, the inlet being in fluid communication with the port, the outlet being in fluid communication with the interior of the shaft at the proximal end of the shaft.

Surgical instruments and methods of cleaning surgical instruments

A bag includes a main compartment configured to accommodate equipment, and a foldable chair compartment disposed adjacent to the main compartment. The foldable chair compartment is configured to accommodate a foldable chair in a folded configuration.

Bag with foldable chair compartment

A surgical instrument component for coupling an end effector to a shaft of a surgical instrument may comprise a distal portion made of an electrically conductive first material, a proximal portion made of an electrically conductive second material, and an intermediate portion made of an electrically insulating third material. The intermediate portion is disposed between and integrally connected to the proximal portion and to the distal portion.

Instruments with electrically isolated components, related systems and methods

A cannula cap is disclosed. A cannula cap according to some embodiments of the invention includes an instrument guide attachment; a cannula attachment; and a seal captured between the instrument guide attachment and the cannula attachment. In some embodiments, a cannula cap can include a lid; a locking ring; a base; and a cannula seal captured between the lid and the base.

A surgical apparatus comprises an instrument shaft having a proximal end and a distal end, an end effector coupled to the distal end of the shaft, and a sheath disposed on an external surface of the instrument shaft. The sheath has a first section made of ePTFE and a second section made of a second material, wherein the second section provides a friction seal with the shaft, and wherein the ePTFE is gas-permeable.

Sheath for surgical instrument

In accordance with aspects of the present invention, a door mechanism is provided. A door mechanism according to some embodiments of the present invention includes a door that includes a sealing part, an arm connected to the sealing part, and a pivot part connected to the arm, the door rotating around a pivot axis at the pivot part; and a lever, the lever engaging the door at the pivot part such that the lever opens the door when engaged but is not affected when the door is opened without the lever.

An articulatable member includes a distal end, a proximal end, an actuation member, and a constraint member. The actuation member extends from the proximal end to the distal end. The actuation member transmits force to bend the articulatable member from a neutral position. The constraint member extends from the proximal end to the distal end. The constraint member may have opposite ends that are fixed to the distal end and the proximal end. In one embodiment, the constraint member follows a helical path along at least a portion of the articulatable member from the proximal end to the distal end. In another embodiment, the actuation member follows a helical path along at least a portion of the articulatable member.

Articulatable members having constrained motion and related devices and methods
