Anti-skid surgical instrument for use in preparing holes in bone tissue
Described herein is an anti-skid surgical instrument for use in preparing holes in bone tissue. The disclosed surgical instrument provides the ability to prepare a precise hole in bone tissue during surgery (e.g., spinal surgeries and pedicle screw placement, intramedullary screw placement). The disclosed surgical instrument accomplishes precise hole placement regardless of whether the angle between the drill axis and surface of the bone tissue is perpendicular. The disclosed technology includes a flat drilling surface which is perpendicular to the surface of the body of the surgical instrument. This reduces the likelihood of the surgical instrument skidding on the surface of the bone tissue and thereby increases the precision of the hole.
Universal instrument guide for robotic surgical systems, surgical instrument systems, and methods of their use
Described herein are systems and apparatus of surgical instruments engineered for integration with robotic surgical systems to enhance precision in surgical procedures. Also described herein are methods of using such surgical instruments in performing surgical procedures. The use of such surgical instruments reduce complications arising from misalignment during surgery. The disclosed technology assists in stages of a surgical procedure that require a precise trajectory to be followed. Surgical instrument guides are attached to a universal surgical instrument guide, which is engineered to attach directly or indirectly with a robotic arm of a robotic surgical system. Surgical instruments can then be precisely guided along an axis defined by the universal surgical instrument guide. Individual instruments are easily inserted and removed from the channel of the universal surgical instrument guide, thus allowing a range of instruments to be used throughout a procedure while maintaining the surgical trajectory.
Apparatus and method for minimally invasive osteosynthesis of sacroiliac luxations/fractures
The disclosure relates to a surgical system and related methods to facilitate reduction and fixation of sacro-iliac luxations/fractures (SIL/F) in small animals, for example dogs and cats. In another aspect, the disclosure relates to an aiming device and related methods providing accurate, reliable, and safe fixation of SIL/F in such small animals. The surgical system includes a work surface, an articulatable and lockable reduction arm mounted to the work surface, a reduction handle mounted to the reduction arm; an articulatable and lockable fixation arm mounted to the work surface, a fixation drill guide mounted to the fixation arm, and an image acquisition unit directed toward the work surface. The surgical system provides enhanced safety to surgical personnel using the system in terms of reduced exposure to harmful radiation form the image acquisition unit.
Interlaminar lumbar interbody fusion implants, intradiscal implants, instruments, and methods
Orthopedic implants, systems, instruments, and methods. A bi-portal lumbar interbody fusion system may include an expandable interbody implant and minimally invasive pedicle-based intradiscal fixation implants. The interbody and intradiscal implants may be installed with intelligent instrumentation capable of repeatably providing precision placement of the implants. The bi-portal system may be robotically-enabled to guide the instruments and implants along desired access trajectories to the surgical area.
Surgical access instrument
In one embodiment, an access instrument for creating a surgical working portal includes a body having a first end and a body length, a first slot having a first slot length running along the length of the body from the first end, and a second slot having a second slot length running along the length of the body from the first end, wherein the first slot length and the second slot length are less than the body length.
Percutaneous discectomy kit and method
A method for performing an efficient and thorough percutaneous discectomy includes making into the patient a percutaneous incision, which is a small stab wound, no more than approximately 10 mm in length. A stimulated combination neuro-monitoring dilating probe is passed through an approximately 10 mm or less skin incision and into a patient's disc space to establish a safe path and trajectory through Kambin's Triangle. Once a neuro-monitoring dilating probe is in the disc space, a second dilator is placed over the neuro-monitoring dilating probe and impacted into the disc space. Neuro-monitoring dilating probe may then be removed. An access portal optionally combined with a force dissipation device may then be placed over the second dilator and into the disc space. The second dilator is removed and then discectomy instruments may be placed through the access portal to perform the discectomy.
DETERMINING RELATIVE 3D POSITIONS AND ORIENTATIONS BETWEEN OBJECTS IN 2D MEDICAL IMAGES
Systems and methods are provided for processing X-ray images, wherein the methods are implemented as a software program product executable on a processing unit of the systems. Generally, an X-ray image is received by the system, the X-ray image being a projection image of a first object and a second object. The first and second objects are classified and a respective 3D model of the objects is received. At the first object, a geometrical aspect like an axis or a line is determined, and at the second object, another geometrical aspect like a point is determined. Finally, a spatial relation between the first object and the second object is determined based on a 3D model of the first object, a 3D model of the second object, and the information that the point of the second object is located on the geometrical aspect of the first object.
Spinal plate system and related methods
Implementations of devices for use in cervical spinal operations. Implementations may include a template including a central hole therethrough and two or more screw holes therethrough. The central hole may be configured to be inserted over a handle of a trial. The template may be configured to place a first of the two or more screw holes over a rostral vertebra and to place a second of the two or more screw holes over a caudal vertebra. Implementations may also include a template including a central hole therethrough and two or more screw holes therethrough. The central hole may be configured to couple over an inserter. The template may be configured to place a first of the two or more screw holes over a rostral vertebra and to place a second of the two or more screw holes over a caudal vertebra.
Interfixated vertebral body replacement and insertion methods
Implants and instruments for providing an ideal trajectory for the insertion of instruments and screws during implantation of an interbody implant in a spinal surgery are disclosed.
Patient-specific navigation guide
A patient-specific navigation guide for use in spinal surgery including a first and a second guide member, both integral with a supporting frame and extending along a respective longitudinal development axis from a proximal opening to a distal opening for guiding surgical instruments on a first vertebra of a patient. The guide also includes contact members designed to match with a corresponding plurality of contact areas on a first and on a second vertebra of the patient to define a single coupling configuration of the patient-specific navigation guide on the patient's vertebrae. The first and second guide members are substantially opposite with respect to a median plane orthogonal to a straight line joining the longitudinal axes of the first and second guide members. The navigation guide also comprises a single additional third guide member that is integral with the frame and is adapted to abut on a second vertebra.
