A medical intervention device may include a distal end comprising a pair of jaws and a handle operably coupled to the distal end. The handle may include a pair of pivoting finger arms each having at least one finger loop, the pivoting finger arms being configured for opening and closing the pair of jaws at the distal end. The handle may also include at least one actuation interface arranged on the handle and in a position distal to the pair of finger arms.

An endoscopic portal protective shield assembly has an elongate portal shaft and an elongated protective shield. The elongate portal shaft has a viewing portal. The shaft has a slotted tubular body with interior surfaces. The shaft has a distal end and a proximal end and a slotted opening at the distal end extending partially along the slotted tubular body toward the proximal end. The elongated protective shield has a longitudinal shield body, a proximal end and a distal end. The protective shield is configured to be slid into the slotted opening of the tubular body with an interior portion of the longitudinal shield body being inserted inside the tubular body while maintaining the viewing portal open.

A cutting guide for a robotic surgical system can include a cutting block defining a guide surface to guide a cutting instrument along a trajectory, an arm connected to the cutting block to couple the cutting guide to the robotic surgical system, and a first retractable shield configured to extend from a first retracted position dear of the trajectory to a second deployed position within the trajectory.

A surgical stapler is provided that includes a first jaw and a second jaw. The first jaw includes a proximal end portion and a distal end portion. The second jaw includes a proximal end portion and a distal end portion. The proximal end portion of the first jaw is pivotally mounted to the proximal end portion of the second jaw. A flexible guide is secured to the distal end portion of the first jaw.

According to an aspect of the present disclosure, an end effector for use with a surgical device is provided. The end effector includes a drive assembly, a driver, a needle assembly and a biasing element. The driver is disposed in mechanical cooperation with the drive assembly. Rotation of the drive assembly in a first direction causes distal translation of the driver with respect to the drive assembly. The needle assembly is disposed in mechanical cooperation with the driver. Distal translation of the driver causes a corresponding distal translation of the needle assembly. The biasing element is disposed in mechanical cooperation with the needle assembly and is configured to bias the needle assembly proximally.

A cutting device for surgical threads comprises a guide body that has an internal axial cavity and a first cutting area defined by an abutment surface; a cutting body that has a central portion that extends along a longitudinal axis and a second cutting area defined by an abutment surface, wherein the second cutting area abuts the second first cutting area when the cutting body is received in a housing portion of the guide body; and an actuator element capable of causing the cutting body to rotate relative to the guide body about the longitudinal axis between a first position, in which the first and second cutting areas, define a passageway that communicates with the internal axial cavity, and a second position, in which said passageway is at least partially obstructed by a counter-rotating movement of the abutment surfaces, which intersect tangentially so as to cut the surgical thread therebetween.

Methods of cutting bone using a robotic cutting system are provided. The robotic cutting system includes one or more controllers, a robotic manipulator, and one or more cutting tools, such as those including a bur or a saw blade, that can be coupled to the robotic manipulator. An initial cut, such as a notch, is made into the bone with the bur or the saw blade. This notch is then used to constrain the saw blade for limiting skiving of the saw blade during cutting along a cutting plane.

Medical devices and related methods for transforming bone, other tissue, or other material are disclosed herein. According to an aspect, a cutting device includes a static casing that defines a sheathing slot and an opening. The sheathing slot extends to the opening and has a first height at an end of the opening. Further, the bone cutting device includes a horn including a first end and a second end. The first end is configured to operatively connect to a source of movement. Further, the second end includes a cutting component having a second height. The first height is greater than the second height.

Methods for selectively attaching a shaft assembly to a handle of a surgical instrument and an arm of a surgical robot are disclosed.

Provided is an epidural device configured to inhibit or substantially or completely prevent further progression of an epidural needle upon entry of the needle into the epidural space. When the needle is inserted into the ligamentum of the patient's back, the device may be pressurized with fluid using the resistance of the dense ligament to maintain pressure. This pressurization may lock a pushing mechanism in place relative to the needle such that the pushing mechanism can be used to advance the needle. Once the epidural space is reached, the fluid (e.g., saline or air) enters the epidural space, and the release of pressure may cause the trigger mechanism to disengage from the sliding pusher, allowing the pusher to slide along the body of the construct. The device thus may provide the ability to detect the epidural space using pressure loss while preventing the needle from advancing into the dura once the space is reached. In a preferred aspect, the device may prevent premature triggering when there is a slow flow of fluid from the epidural needle into the surrounding tissue.
