EXTRA JOINT STABILIZATION CONSTRUCT
The disclosure provides devices and methods of use pertaining to extra joint stabilization. Embodiments include a number of suture returning and locking anchors that feature both a suture return element and a suture locking feature that employs an interference fit between a flexible synthetic strand, a receiver of the anchor, and a set screw, where the receiver and the set screw each have a number of gradual, opposing tapers to facilitate gradual proximal-to-distal gripping and releasing of the flexible strand to achieve an optimal locking force while preventing severing of the flexible strand. Embodiments also include a counter-torque anchor driver configured to resist torsional forces generated during and translated to the anchor during set-screw insertion. Further embodiments include extra joint reinforcement, stabilization, and attachment constructs formed using the disclosed devices. Other embodiments are disclosed.
COMPRESSION AND TENSION INSTRUMENTS AND METHODS OF USE TO REINFORCE LIGAMENTS
The disclosure provides apparatus and methods of use pertaining to syndesmosis reinforcement. Embodiments include a clamp having two jaws that extend toward each other to clamp two bone portions therebetween. The clamp may include an angle gauge and an adjustment mechanism having a force gauge that combine to enable the compression of the two bone portions in an optimal direction or angle and at an optimal, measurable compression force. Embodiments also include a tension instrument configured to knotlessly lock a flexible strand construct between two anchors at the same optimal direction and tension applied by the clamp. Further embodiments include an exemplary syndesmosis reinforcement procedure that employs the clamp and the tension instrument to construct a ligament reinforcement construct that achieves optimal anatomic positioning in both directional alignment and the reduction force applied by the construct. Other embodiments are disclosed.
SURGICAL ROBOTIC AUTOMATION WITH TRACKING MARKERS
A surgical robot system includes a robot. The robot includes a robot base and a robot arm coupled to the robot base. The robot also includes an end-effector coupled to the robot arm. The robot is configured to control movement of the end-effector to perform a surgical procedure. The robot also includes an inertial measurement unit coupled to the robot arm. The surgical robot system also includes camera that is configured to capture one or more pictures or videos used to determine a location of the end-effector. The inertial measurement unit is configured to capture one or more measurements used to determine the location of the end-effector when a view of the camera is occluded.
Intra joint stabilization construct
The disclosure provides devices and methods of use pertaining to intra joint stabilization. Embodiments include a number of suture returning and suture locking anchors that feature elongated sleeves configured to protect the associated bone tunnels from suture wipering, which results in abrasion and enlargement of the bone tunnel and leads to migration of the suture anchors. Embodiments also include suture locking anchors that lock via an interference fit between the suture strand and a receiver of the anchor and a set screw, where the receiver and the set screw each feature a number of gradual, opposing tapers to facilitate gradual proximal-to-distal gripping and releasing of the suture strand to achieve an optimal locking force while preventing severing of the suture strand. Further embodiments include intra joint reinforcement and stabilization constructs formed using the disclosed devices. Other embodiments are disclosed.
SPINAL SPACING IMPLANT, SPINAL SPACER ASSEMBLY, EXPANDER AND INSERTION INSTRUMENT, KIT AND METHODS OF ASSEMBLY AND USE
Spinal spacing implants, spinal spacer assembly, expander and insertion instruments, kits and methods of assembly and use are disclosed. The spinal implant replacement instrument kit including a distraction instrument, a spacer inserter, and a spinal implant. A distraction instrument includes a first inserter member, a second inserter member, a first arm coupled to the first inserter member, a second arm coupled to the second inserter member, a distraction system coupled to the first arm and second arm, a first handle coupled to the first arm and the distraction system, and a second handle coupled to the second arm and the distraction system. Spinal spacing implants, spinal spacer assemblies, and methods of assembling and using the implants assemblies, and instruments are also disclosed.
DISTRACTION/COMPRESSION APPARATUS AND METHOD FOR BONE
Apparatus and methods for distracting and/or compressing bone. An exemplary apparatus may comprise a rod having a thread. The apparatus also may comprise a first assembly and a second assembly each coupled, or configured to be coupled, to the rod and each configured to be attached to a respective pin extending into bone. The apparatus further may comprise a nut engaged, or configured to be engaged, with the thread and configured to be turned to drive the second assembly along the rod. In some embodiments, at least one of the assemblies may have at least two degrees of rotational freedom that can be eliminated by manipulating a single graspable member. In some embodiments, the rod and the second assembly may have anti-rotation features configured to interact with one another to permit travel of the second assembly along the rod while preventing rotation of the second assembly about the rod.
ALIGNMENT APPARATUS FOR USE IN HIP ARTHROPLASTY
Hip arthroplasty apparatus and methods are described to determine an orientation of an acetabular cup impactor, the acetabular cup impactor being moveable to a desired orientation relative to a patient's pelvic region for implantation of an acetabular cup. In one embodiment an electronic orientation sensor is transitionable between a first location on the patient's pelvic region and a second location on the acetabular cup impactor. At the first location, the orientation sensor is adapted to record a reference orientation of the patient's pelvic region. At the second location the orientation sensor is adapted to determine an orientation of the acetabular cup impactor relative to the reference orientation.
Intramedullary implant and method of use
A bone implant includes a proximal end, a distal end, a first portion extending between the proximal and distal ends having a maximum and minimum portion height, and a second portion extending between the proximal and distal ends having a maximum and minimum portion height. The second portion is connected to the first portion at the proximal end and the distal end and at least one of the first portion and the second portion is moveable relative to the other of the first portion and the second portion so as to transition the bone implant between a relaxed state wherein the first and second portions are separated by a first distance and a contracted state wherein the first and second portions are separated by a second distance different from the first distance. At least one of the proximal end and the distal end have the minimum portion height.
Electronically assisted medical device
An electronically assisted artificial vertebral disc having an upper disc plate and a lower disc plate is disclosed. An actuator imparts movement to at least one of the upper and lower disc plates. A control device controls the actuator and the amount of movement between the disc plates. The actuator includes a plurality of either linear actuators or rotary actuators that are driven by electric motors in response to the control device. The control device includes at least a first sensor for detecting the position of the actuator and at least a second sensor for detecting the spatial orientation of at least one of the upper and lower disc plates. The control device also preferably includes a microprocessor that calculates the desired positions of the upper and lower disc plates and provides a control signal to the actuator to drive the upper and lower disc plates to their desired positions.
Alignment apparatus for use in hip arthroplasty
Hip arthroplasty apparatus and methods are described to determine an orientation of an acetabular cup impactor, the acetabular cup impactor being moveable to a desired orientation relative to a patient's pelvic region for implantation of an acetabular cup. In one embodiment, an electronic orientation sensor is transitionable between a first location on the patient's pelvic region and a second location on the acetabular cup impactor. In a second embodiment, an image capture device is locatable on the acetabular impactor or the patient's pelvic region to capture images including markers located on the other of the patient's pelvic region or the acetabular impactor.
