A medical device comprising a handle extending between a first end and a second end, a first actuator coupled to the first end of the handle, a first shaft coupled to the second end of the handle, and a second shaft extending from the first shaft, the second shaft including a first articulation section and a second articulation section, wherein an articulation of the first actuator relative to the handle is configured to articulate the first articulation section, an articulation of the handle relative to the first shaft is configured to articulate the second articulation section, and the first articulation section and the second articulation section are restricted to articulating only in a first plane.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.

Methods and devices for reprocessing a surgical instrument are disclosed. The surgical instrument includes a housing defining a cavity and at least one interior component disposed within the cavity. The housing is opened along a seam to access the cavity, the at least one interior component is serviced, and a mating member is applied to the housing. The housing is joined together with the mating member, and the housing is reopened along the seam to access the cavity.

A medical device includes a handle that includes a handle body longitudinally extending from a proximal end to a distal end; a distal connector configured to connect to a proximal end of an elongate outer member; a lumen longitudinally extending through the handle body, the lumen configured to have an elongate inner member movably disposed therein, and to permit the elongate inner member to distally extend past the distal end to within the elongate outer member and to proximally extend past the proximal end; and an inner member controller configured to longitudinally move relative to the handle body to control movement of the elongate inner member relative to the elongate outer member. The handle may be a distal handle of the medical device, which further includes a proximal handle. Both handles may control movement of the elongate inner and outer members.

A surgical instrument (10), comprising: a surgical execution component (100), a linkage part (200), and a manipulation component (300), the distal end of the linkage part (200) being connected to the surgical execution component (100) and the proximal end of the linkage part (200) being connected to the manipulation component (300). The surgical instrument (10) uses the linkage part (200) having two rotational degrees of freedom, such that when the manipulation component (300) drives, by means of the linkage part (200), the surgical execution component (100) to rotate at a fifth rotational degree of freedom (R5) and/or a sixth rotational degree of freedom (R6), the swing directions of the surgical execution component (100) and the manipulation component (300) at a first rotational degree of freedom (R1) and a second rotational degree of freedom (R2) are consistent. Therefore, the surgical instruction (10) implements technical effects of improving the moving direction accuracy of the surgical execution component (100), improving the accuracy of the action of the surgical instruction (10), and facilitating surgical operations.

A surgical apparatus comprising: a mechanism that is configured to perform an operational motion of the surgical apparatus; and at least one transformation member having an original shape and a deformed shape, the at least one transformation member connecting the mechanism together, when the at least one transformation member is in the deformed shape so that the mechanism is capable of performing the operational motion; and wherein after the transformation member is subject a transition temperature, the at least one transformation member changes from the deformed shape to the original shape and disengages a portion of the mechanism so that the mechanism is prevented from performing the operational motion.

A surgical system according to an embodiment may include a patient-side apparatus, an operator-side apparatus including an operation part to receive an operation for operating a surgical instrument attached to an arm of the patient-side apparatus, and a controller configured to control an operation of the surgical instrument based on the operation received by the operation part. The controller is configured to: control rotation amounts of first and second drive parts to drive first and second elongate elements for opening and closing first and second jaw members of the surgical instrument such that an opening angle between the first and second jaw members correspond to an operating angle received by the operation part; and correct, according to a rotation angle of a shaft of the surgical instrument about a rotation axis of the shaft, the rotation amounts of the first and second drive parts that correspond to the operating angle.

In various embodiments, a layer of material can comprise a body, a proximal end portion, and a distal end portion. The proximal end portion can be releasably secured to a staple cartridge of a surgical end effector, and the distal end portion can be releasably secured to an anvil of the surgical end effector. The layer of material can comprise a tissue thickness compensator.

A medical instrument includes a housing, a movable handle, and a spring. The movable handle is configured to move between a first position as an opened position and a second position as a closed position with respect to the housing. The spring is provided between the housing and the movable handle. The spring is configured to apply a biasing force to the housing or the movable handle. The spring is provided to alleviate an increase in the biasing force generated in the spring in response to the movable handle moving from the first position to the second position.
