A fixing device and an installation tool and a fixing method of the cranial flap, wherein the installation tool comprises a driving part, a loading part and an over torque protection mechanism disposed between the driving part and the loading part, the driving part drives the loading part to rotate by the over torque protection mechanism, the loading part is used for tightening the cranial flap fixation device, when the torque of the driving part acting on the over torque protection mechanism is larger than the threshold value, the over torque protection mechanism will be separated from the driving part and/or the loading part. The present invention not only effectively improves the installation and disassembly efficiency of the installation tool, but also eliminates hidden safety hazards caused by uncertainties caused by human factors in the tightening process, significantly improves the safety of the installation process.

A knife limit for a surgical instrument includes a housing having a shaft extending therefrom configured to support an end effector at a distal end thereof, the end effector including first and second jaw members. One or both of the jaw members including a knife channel defined therein and extending therealong to a distal portion thereof. A knife assembly is disposed within the housing and cooperates with a trigger to translate a knife within the knife channel to the distal portion of the jaw member upon actuation thereof. A knife limit button is disposed within the housing and is configured to limit the distal translation of the knife within the knife channel upon selective actuation thereof. The knife limit button is movable between a first position allowing full translation of the knife within the knife channel and a second position limiting distal translation of the knife within the knife channel.

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.

A surgical instrument comprising a jaw assembly is disclosed. The surgical instrument further comprises a motor-driven drive system configured to open the jaw assembly. The surgical instrument also comprises a control system configured to control the drive system and, also, control a power supply system configured to supply electrical power to electrodes defined in the outer surface, or outer surfaces, of the jaw assembly. In use, the surgical instrument can be used to apply mechanical energy and electrical energy to the tissue of a patient at the same time, or at different times. In certain embodiments, the user controls when the mechanical and electrical energies are applied. In some embodiments, the control system controls when the mechanical and electrical energies are applied.

A system for robotic surgery makes use of an end-effector which has been configured so that a drill connected thereto is guided in its trajectory and limited in its advancement into an associated anatomical feature by a drill guide. The drill guide may be adjusted manually to engage a corresponding surface of the drill after its advancement by a pre-selected amount. The drill guide likewise includes features to guide the drill during trajectories having oblique angles relative to the surface of the anatomical feature associated with the medical procedure.

A spinal construct comprises at least one member that defines a first implant cavity and a second implant cavity oriented transverse to the first implant cavity. The at least one member has a surface that includes a lock disposed with the first implant cavity. Systems, implants, surgical instruments and methods of use are disclosed.

A treatment tool includes: a pair of grippers configured to grip living tissue, at least one of the pair of grippers being configured in an openable and closable manner; a transmission portion connected to the at least one of the pair of grippers, the transmission portion being configured to move forward and backward along a first direction to open and close the pair of grippers; an operating portion configured to receive user operation for gripping the living tissue; an elastic body configured to transmit, to the transmission portion, an operating force applied to the operating portion by the user operation while being compressively deformed in accordance with the operating force; and an adjustment mechanism configured to adjust an amount of compressive deformation of the elastic body when the user operation is performed on the operating portion, to thereby adjust a gripping force of the pair of grippers.

Certain aspects relate to systems and techniques for surgical robotic arm setup. In one aspect, there is provided a system including a first robotic arm configured to manipulate a medical instrument, a processor, and a memory. The processor may be configured to: determine a minimum stroke length of the first robotic arm that allows advancing of the medical instrument by the first robotic arm to reach a target region from an access point via a path, determine a boundary for an initial pose of the first robotic arm based on the minimum stroke length and a mapping stored in the memory, and during an arm setup phase prior to performing a procedure, provide an indication of the boundary during movement of the first robotic arm.

A fastener cartridge can include, one, a cartridge body comprising a deck and a plurality of fastener cavities and, two, a plurality of fasteners positioned in the fastener cavities. The cartridge body can further comprise extensions extending from the deck having different sizes and/or configurations. The extensions can control the flow of tissue relative to the deck and/or support the fasteners as they are ejected from the fastener cavities.

Systems and methods for minimally invasive tele-surgery are described. For example, the disclosure describes methods for independently controlling motions of the robotic manipulator, cannula, and surgical instrument in various surgical contexts.
