This disclosure relates to drill guides and depth control apparatus for use with a variety of customized or standardized surgical instruments. In embodiments, the apparatus comprises at least a body portion and a collar portion, one or more of which are configured to be coupled to a cutting instrument, such as a drill bit, in a specified location and manner to prevent unwanted movement. In embodiments, the assembly of the body and collar portions may be incrementally adjusted to alter the desired depth of the cutting instrument. Methods for using the foregoing apparatus are also disclosed herein.

The combination of a marker system with binocular AR glasses to create a soft tissue procedure system used for surgery, biopsies, etc. A marker localization system is functionally integrated with augmented reality (AR) glasses. This soft tissue system can be applicable for AR surgeries in soft tissues involving mobile and static anatomies anywhere in the body, such as for example, breast, soft tissue, lungs, lymph nodes, liver surgeries, etc. By the placement of single or multiple markers and localizing the markers with a locator, such as a hand-held locator as a non-limiting example, the above-mentioned system provides a real-time intraoperative coordinate frame for the virtual projection of the markers (and the associated ROI) on/in the surgical field/biopsy field of view, using commercial off-the-shelf computer hardware (laptops, tablets, etc.) for the required image processing.

A variety of configurations of implant management devices are provided. The configurations provide different combinations of features for maintaining a location of an implant with respect to the device and managing filaments of the implant. One exemplary embodiment of a device includes a generally rectangular-shaped body having an implantable body retainer, an opening disposed a distance apart from the retainer and configured to receive a ligament graft therein, and a fold extending across the body and intersecting the opening. Folding one end of the body towards a bottom surface of the body along the fold can form a filament loop engaging region to hold in tension a filament loop extending from the implant. Additional filament(s) associated with the implant can be managed by various filament retention features. Methods for preparing a ligament graft for implantation by relying upon indicia formed on a surface of the device body are also provided.

An example catheter caliper according to the present disclosure includes a tube having a plurality of markers at predetermined intervals and a wire extending from the tube, wherein the catheter caliper is configured to be received into the vasculature of a patient. Other example catheter calipers and example methods of using the catheter caliper is also disclosed.

An ablation device for the treatment of an eye to lower intraocular pressure including a handle; and an array of rods projecting from a distal end region of the handle and electrically-connected to an energy delivery generator. Each rod of the array of rods is configured to create a cavity in a surface of the eye via ab externo tissue ablation to enhance drainage of aqueous humor from the eye. Related devices, systems, and methods are provided.

Systems and methods for image-guided medical procedures use fluoroscopic 3D reconstructions to plan and navigate a percutaneously-inserted device such as a biopsy tool from an entry point to a target.

A surgical system comprises a manipulator arm, configured to secure to a base, and an actuator assembly. The actuator assembly includes an instrument mounting bracket and a plurality of actuator disks supported on a first end of the instrument mounting bracket. The surgical system also includes a surgical instrument including a plurality of interface disks supported on a face of the surgical instrument. The plurality of interface disks is configured to mate with the plurality of actuator disks. The instrument also includes an attachment mechanism configured to removably attach the surgical instrument to the actuator assembly and an instrument body tube extending from the face of the surgical instrument. The instrument body tube is capable of passing by or passing through the instrument mounting bracket when the surgical instrument is attached to the instrument mounting bracket.

A composition and methods of making or use thereof include a plurality of fibers forming a shape for augmenting fixation of a bone screw, or the plurality of fibers form a shape having a peg portion and a sheet portion to augment tendon to bone repair. The physical presence of the plurality of fibers provides initial fixation, while the use of an osteoinductive material provides long term enhancement of bone formation around the site of the bone screw or the tendon to bone repair.

A method of assembling a measurement module used for bore depth determinations in tissue. The measurement module has a housing. A gear having a plurality of gear teeth is disposed within and rotatably coupled to the housing. The measurement module further includes a bushing and a depth extension member having a plurality of rack teeth extending along a depth extension axis. The depth extension member is disposed within a bore of the bushing and the housing. The rack teeth of the depth extension member are arranged to be engaged by the gear teeth of the gear. The depth extension member is urged toward the gear so that the rack teeth are in meshed engagement with the gear teeth. The bushing is fixed to the housing while the depth extension member is urged toward the gear.

In certain embodiments, an ophthalmic system includes an anamorphic depth gauge (ADG) device and a computer. The ADG device measures the z-location in the interior of an eye and includes a detector array arranged at an oblique angle with respect to the z-axis. The array generates a detector signal in response to detecting a light beam, which has a z-focus in the interior of the eye. A set of line focus optical elements focuses the light beam to form a line focus on the detector array, and a set of nominal focus optical elements focuses the light beam to form a nominal focus on the detector array. The computer: generates an image using the detector signal; determines the position of the nominal focus on the line focus according to the image; and determines the z-location of the z-focus from the position of the nominal focus on the line focus.
