摘要:
A surgical instrument assembly comprising an end effector, a shaft assembly, a closure drive system, and a firing drive system is disclosed. The surgical instrument assembly further comprises a dual lock configured to engage a closure member and a firing member to prevent the firing member from being advanced distally from a proximal firing stroke position before the closure member is in a distal closure stroke position. The dual lock is further configured to prevent the closure member from being retracted from the distal closure stroke position before the firing member is returned to the proximal firing stroke position after the firing stroke.

A shaft assembly is disclosed which is usable with a surgical system, such as a surgical robot and/or a handle of a surgical instrument, for example. The shaft assembly is configured to receive a rotary input motion from the surgical system and a transmission, or clutch, which is shiftable between a first operating mode and a second operating mode to selectively transmit the rotary input motion to a first drive system and a second drive system.

Coupling systems for removably coupling dual rotary drive shafts of a surgical instrument to corresponding driven shafts of a surgical end effector. The surgical instrument may include a first rotary drive shaft that includes a first drive shaft axis and a second rotary drive shaft that includes a second drive shaft axis. The second drive shaft axis may be offset from and parallel with the first drive shaft axis. The coupling systems may facilitate simultaneous operable attachment of the first and second drive shafts of the surgical instrument with corresponding first and second driven shafts of a surgical end effector such that rotation of the first drive shaft rotates the first driven shaft and rotation of the second drive shaft rotates the second driven shaft.

A deployment mechanism for selectively deploying and retracting an energizable member and/ an insulative member relative to an end effector assembly of a surgical instrument includes one or more actuators, a clutch assembly, and a drive assembly. The clutch assembly is configured to couple to the actuator(s) to provide rotational motion in the first direction in response to such rotation of the actuator(s) and to decouple from the actuator(s) in response to rotation thereof in the second direction. The drive assembly is operably coupled to the clutch assembly and is configured to convert the rotational motion provided by the clutch assembly into longitudinal motion to translate the energizable member and/or insulative member from a storage position to a deployed position and to translate the energizable member and/or the insulative member from the deployed position back to the storage position.

Methods and apparatus are provided for closing incisions within biological tissue. In one embodiment, a device and method are provided for suturing biological tissue, such as, for example, an organ or blood vessel. The suturing apparatus is particularly well suited for suturing an incision made in an artery, such as the femoral artery, following a catheterization procedure. The device eliminates the need to apply pressure to a patient's thigh for an extended period of time, and eliminates many of the complications and costs associated with the creation of a thrombus patch. In addition, the device comprises an improved handle portion which enables the physician to quickly and easily apply suture. The handle portion is very reliable and easy to manipulate. The suturing may be used in combination with existing catheter sheath introducers.

An end effector for use with a surgical fastening instrument is disclosed which comprises a staple cartridge and an anvil. The staple cartridge comprises a cartridge body including a deck and, in addition, fasteners removably stored in the cartridge body, wherein each fastener comprises a base and a leg extending from the base. The anvil comprises a tissue compression surface and forming pockets defined in the tissue compression surface. Each forming pocket comprises a first end configured to receive a staple leg, a second end, a central axis extending between the first end and the second end, a concave turning surface extending between the first end and the second end, and a channel defined in the concave turning surface, wherein the channel is laterally offset from the central axis.

A handle assembly for a surgical instrument is disclosed. In at least one form, the handle assembly comprises a primary housing portion that is configured to be operably coupled to a portion of a surgical tool assembly. At least one drive system is operably supported by the handle assembly and is configured to selectively apply at least one drive motion to the surgical tool assembly that is coupled thereto. A grip portion is movably coupled to the primary housing portion and is selectively movable to a plurality of grip positions relative to the primary housing portion. A grip locking system interfaces with the primary housing portion and the grip portion to selectively releasably retain the grip portion in any one of the plurality of grip positions.

The invention provides a surgical instrument and a bending control mechanism. The bending control mechanism comprises a turning power input mechanism A, a turning transmission mechanism B, a locking mechanism C and a linear power output mechanism D; further, the turning power input mechanism A and the turning transmission mechanism B which are coaxially arranged have a relative rotating angle range in the circumferential direction; the turning power input mechanism A sequentially rotates in an angle I, an angle range II and an angle III while rotating relative to the turning transmission mechanism B from one end angle to the other end angle within a relative rotating angle range, wherein the angle I or the angle III corresponds to turning; the angle range II corresponds to a locking state. With the adoption of the mechanism, the problem of turning and fixing of the surgical instrument in a human body during surgery can be solved, and the risk of surgery can be reduced.
