A surgical stapling device includes a reload assembly that includes a locking member to retain a knife carrier of the reload assembly in a retracted position after the stapling device is fired. The locking member may be supported on an inner housing portion of the shell housing or on a staple pusher assembly of the reload assembly.

A surgical instrument includes a shaft and a probe that extends distally from a distal end of the shaft. The probe includes a distal tip configured to puncture a tissue surface to enter a nerve canal of a patient, and an ablation element operable to ablate a nerve located within the nerve canal. The surgical instrument further includes a stop element arranged proximally of the distal tip. The stop element is configured to abut the tissue surface punctured by the distal tip. In some examples, the ablation element may be in the form of an RF electrode operable to ablate the nerve with RF energy. The surgical instrument may further include a navigation sensor operable to generate a signal corresponding to a location of the probe within the patient.

A surgical suturing tracking system is disclosed. The surgical suturing tracking system is configured to detect and guide a suturing needle during a surgical suturing procedure. The surgical suturing track system comprises a control circuit configured to predict a path of a needle suturing stroke after receiving an input from a clinician, detect an embedded tissue structure, and assess proximity of the predicted path and the detected embedded tissue structure.

A system comprises a teleoperational manipulator configured to control operation of a medical instrument in a surgical environment. The system further comprises an operator input system including an input device and a processing unit including one or more processors. The processing unit is configured to display an image of a field of view of the surgical environment and display a menu including a set of directionally arranged menu options. The processing unit is further configured to transition the input device from a first constraint state for interaction with the medical instrument to a second constraint state for interaction with the menu. In the second constraint state, the input device is constrained to move in one or more directions based on the set of directionally arranged menu options.

An intravascular catheter device includes an expandable portion secured to a flexible catheter tube and configured for controllable movement between a first position where at least a portion of each of a plurality of struts is moved outward so as to extend beyond an outer surface of a sheath and a second position where the struts are compressed. A limiter for restricting expansion of the expandable portion is interposed between the expandable portion and a tip member located distal to the expandable portion. An incising element associated with one of the struts is configured to incise tissue located within a blood vessel when the expandable portion is placed in the first position and retracted axially along the blood vessel.

A video endoscope that includes a handle with a housing and an interface portion rotatably mounted relative to the housing, and an elongate shaft with one or more electronic image sensors, wherein a proximal end section of the shaft is detachably connected to the interface portion of the handle, where the interface portion includes a first connector element electrically connected to an electric transmission element of the interface portion and the shaft includes a second connector element electrically connected to the one or more electronic image sensors, the first and second connector elements co-operating to form a detachable electrical connection, and where the handle includes an electrical connection assembly arranged at an exterior of the interface portion forming an electrical connection to at least one stationary electric and/or electronic component of the handle in a multiplicity of rotational positions of the interface portion relative to the housing.

A guide assembly including a guide nose, a body supporting the guide nose, and a torque limiter having a configuration to connect the guide nose and the body to a separate structure. A method for negotiating a restriction in a borehole including running a guide assembly into the borehole, encountering a restriction with the guide nose, limiting torque on the guide nose while encountering the restriction, longitudinally unloading the guide nose, incrementing an incrementing feature of the guide assembly to thereby rotate the guide nose. A wellbore system including a borehole in a subsurface formation, a string in the borehole, a guide assembly disposed within or as a part of the string.

A telesurgical system operates in a first operating mode and in a second operating mode. In the first operating mode, a moveable component is driven within a first range of an operating parameter. In the second operating mode, the moveable component is driven with a second range of the operating parameter, less than the first range. Usable instrument life is increased by decreasing mechanical degradation of the moveable component as a result of operating in the second range. A surgeon may select either operating mode.

An arthroscopic cutting probe includes an outer sleeve having a longitudinal bore and an outer cutting window at its distal end. An inner sleeve is rotationally disposed in a bore of the outer sleeve, and the inner sleeve has a distal end, a proximal end, a longitudinal passageway, and an inner cutting window at its distal. An active electrode sleeve is disposed on an outer surface of the inner sleeve in a position opposed to the inner cutting window. Rotation of the inner sleeve relative to the outer sleeve causes the inner cutting window to rotate past the outer cutting window to resect tissue received through the cutting windows as they pass each other. Radiofrequency current can be applied to the active electrode to enhance tissue cutting then the cutting windows are being rotated or to able or cauterize tissue when the cutting windows are held stationary with the active electrode disposed through the outer cutting window.

In general, orthopedic instrument adapters and methods of using orthopedic instrument adapters are provided. In an exemplary embodiment, an adapter is configured to releasably attach to an end effector configured to impact bone. The end effector can be a broach, chisel, or other surgical implement. The adapter includes a spring-loaded hook that is configured to releasably seat in a cut-out formed in the end effector. The adapter is also configured to releasably attach to a surgical impacting tool, such as an orthopedic impactor, configured to drive impacting of the end effector relative to bone.
