Adapters for surgical drilling systems, and methods of use, are provided for performing surgical procedures, such as surgical drilling into bony structures, while guided by a conductivity sensing system. The adapters may be configured to be coupled to a surgical drilling tool such as a conventional surgical drill and a drill bit having conductivity sensing capabilities, or a surgical hand tool having conductivity sensing capabilities. The adapters further include a controller configured to receive one or more signal indicative of measured electrical conductivity and/or penetration depth measurement, detect a condition associated with a change of measured electrical conductivity based on the signal, and arrest advancement of the surgical drilling tool responsive to detection of the condition.

A method may be provided to operate a medical system. First data may be provided for a first 3-dimensional (3D) image scan of an anatomical volume, with the first data identifying a blood vessel node in a first coordinate system for the first 3D image scan. Second data may be provided for a second 3D image scan of the anatomical volume, with the second data identifying the blood vessel node in a second coordinate system for the second 3D image scan. The first and second coordinate systems for the first and second 3D image scans of the anatomical volume may be co-registered using the blood vessel node identified in the first data and in the second data as a fiducial.

A navigation method for a medical operation and implemented by a robotic system is provided. The method includes the steps of: receiving, at a processor of the robotic system, at least one set of navigation data; receiving or generating at least one three-dimensional model of the virtual object in the navigation data; calculating the navigation data to generate a virtual environment and at least one navigation instruction; and presenting, at a user interface associated with the robotic system, the virtual environment and/or the navigation instruction to a user of the robotic system for the user to refer to during the medical operation.

The present disclosure provides methods for forming or enlarging holes in objects. Objects may include bone tissue and methods for fixing matched medical plates to bodies. The movable trocar with toroidal interface is adjustable relative to the surface. The present disclosure also provides for products produced by the methods of the present disclosure and for apparatuses used to perform the methods of the present disclosure.

A bone screw fixation system includes a bone screw body having a screw head at one end of the screw and a screw tip at an opposite end of the screw, the screw head having an internal complex geometric shaped drive and internal threads within the screw head; and a screw inserter compatible with the screw head and having a complex geometric shaped drive configured to matingly engage the internal complex geometric shaped drive of the screw head and a threaded tip configured to thread into the internal threads of the screw head.

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.

Devices and methods for placing an implant between two bone portions are disclosed. In some embodiments, a method comprises disposing a portion of a flexible member through a first bone portion, through an aperture in a trial implant, and through a second bone portion. The trial implant can be withdrawn to enable an implant to be coupled to the flexible member. The method includes applying tension to the flexible member to urge the implant into the space between two bone portions. In some embodiments, the two bone portions are facets.

The present disclosure relates generally to a surgical system. The surgical system comprises one or more surgical instrument assemblies and a surgical navigation system. The surgical instrument assemblies comprises a tracking device capable of being tracked by the surgical navigation system. The surgical system is also configured to allow the user to define one or more alert zones relative to anatomical structures of the patient and/or a surgical pathway. The surgical system further comprises an alert device in communication with the surgical navigation system, such that the alert device is configured to provide a user-perceptible alert to the surgeon or medical professional based on the position of the surgical instrument, as determined by the surgical navigation system, relative to the defined alert zones and/or surgical pathway.

Medical devices for creating or expanding a cavity within bone of a patient are disclosed. In some circumstances, a medical device, such as an osteotome is designed to facilitate simultaneous advancement and articulation of a distal portion of the osteotome. Simultaneous advancement and articulation of the distal portion may reduce one or more forces on the distal portion of the osteotome relative to other methods in which advancement and articulation are separated in time, thereby decreasing the risk of breakage or other damage to the osteotome.

A fixed angle instrument includes an elongate guide extending from a proximal end to a distal end, the guide having a proximal portion extending along a longitudinal axis and a distal portion extending transverse to the longitudinal axis. The instrument further includes a shaft disposed within the guide extending through the proximal portion of the guide along the longitudinal axis. The instrument further includes an intermediate element coupled to the shaft, the intermediate element having at least one bulbous link. The instrument further includes a distal element coupled to a distal end of the intermediate element.
