The present disclosure relates to a lateral sleeve pipe drill and a operating method, belong to the field of surgical instrument technologies, and solves the problems that a bone passage cannot be effectively corrected and is liable to be corrected excessively, and correction is time-consuming and damages important functional bone tissue morphology. The lateral sleeve pipe drill is of a hollow cylindrical shape and includes a first end and a second end. An outer wall of the first end is provided with a correction portion for correcting the bone passage. The first end is arranged in a human body and is of a particular shape adapted to different surgical methods, a surgical approach direction, and a human body internal structure.

A computer-assisted surgery system allows a user to control movements of a surgical tool by providing, to a control unit, inputs in the form of measured displacements via a movable part of a handle while treating a region of interest with the tool. The control unit is configured to enable motion of the tool with respect to an anatomical structure only if a user moves the movable part, receive the measured displacement of the movable part, receive from a localization unit the relative position and orientation of the tool relative to the anatomical structure, based on the measured displacement, on the surgical plan and on the relative position and orientation of the tool relative to the anatomical structure, compute an instruction to send to a motorized joint to move a robotic arm to operate the tool according to an optimal trajectory, and send the computed instruction to the motorized joint.

The present technology relates to surgical drilling devices, and associated systems and methods. In some embodiments, a surgical drilling device includes a drill bit and a retraction mechanism. The retraction mechanism can include a housing, a slide assembly within the housing and operably coupled to the drill bit, a spring element engaging the slide assembly, and a locking element coupled to the slide assembly. The locking element can be movable between a locked configuration and an unlocked configuration based on an amount of force applied by the drill bit to the slide assembly. When in the locked configuration, the locking element can secure the slide assembly to the housing. When in the unlocked configuration, the locking element can allow the spring element to displace the slide assembly proximally within the housing to retract the drill bit.

Systems and methods for treating cellulite including an apparatus that applies or a method involving separating septa to eliminate or reduce the appearance of cellulite. In one approach, an interventional tool is placed between tissue layers to engage and treat septa connecting tissue layers between which fat deposits are contained.

A system and method for cutting soft tissue with a retractable surgical cutting device (10). The device (10) includes a handle (12) having a first channel (24) extending therethrough and a switch (18) located thereon. The switch (18) is movable between a retracted position and an extended position. An actuator (26) with a blade (16) extends through the first channel (24) and connects to the switch (18) within the handle (12). An outer sheath (14) is connected to the handle (12) and surrounds the actuator (26) and at least a portion of the blade (16). A drive mechanism (28) is connected to the switch (18) within the handle (12) such that when the switch (18) moves from the retracted position to the extended position, the actuator (26) moves from a retracted position to an extended position. In the retracted position, the blade (16) can be entirely within the outer sheath (14) and in the extended position, at least a portion of the blade (16) is positioned outside of the outer sheath (14).

A surgical instrument end effector includes a first jaw configured to receive a staple cartridge and a second jaw that includes an anvil having a plurality of staple forming pockets. The first and second jaws are operable to clamp and staple tissue positioned therebetween. A tip member is movably disposed at a distal end of the anvil and is configured to toggle relative to the anvil between a first discrete position and a second discrete position. The tip member in the first discrete position is oriented angularly toward the first jaw, and the tip member in the second discrete position is oriented angularly away from the first discrete position.

An atherectomy system includes a drive mechanism that is adapted to rotatably actuate an atherectomy burr and a controller that is adapted to regulate operation of the drive mechanism. In some cases, the drive mechanism includes a drive cable that is coupled with the atherectomy burr and a drive motor that is adapted to rotate the drive cable. The controller is adapted to receive an indication of an increase in torque experienced at the atherectomy burr and is further adapted to, in response, regulate operation of the drive mechanism such that the increase in torque results in a noticeable reduction in speed of the drive mechanism such that a user of the atherectomy system notices the reduction in speed and is alerted to the increase in torque.

A surgical instrument including one or both of a shield on a distal end portion of a shaft and a counterweight in a handle for enhanced functionality, efficiency and/or efficacy. The shield covers portions of a linkage that extend beyond outer dimensions of the shaft during operation of the instrument. The counterweight is proximal to a hand grip and configured to locate a center of gravity of the instrument within the hand grip. The instrument may be configured as a video-assisted thoracoscopic (VATS) and/or minimally invasive cardiac surgery (MICS) device.

The disclosure relates to an ingress-egress apparatus for protection of a surgical work site during removal of a surgical implant therefrom. The apparatus includes an inverted frustum surface having a sidewall defining: a bottom open area at a base portion of the frustum surface sidewall, and an opposing top open area at a top portion of the frustum surface sidewall. The top open area has a larger area than the bottom open area. The apparatus includes an ingress port located at the base portion of the frustum surface sidewall and an egress port located at the base portion of the frustum surface sidewall. During surgical removal of the surgical implant using a surgical burr, the apparatus can be used to irrigate the work site, thereby cooling it and protecting it from damage, and further removing metal implant particles generated during burring.
