Tools and methods for tissue removal
The present invention is directed to material removal instrument for forming cavities in interior body regions, particularly cavities in intervertebral discs and vertebrae. The instrument includes a cannula and a rotation mechanism disposed at least partially within the cannula. A cutting element extends from the rotation mechanism and impacts and dislocates tissue as the rotation mechanism is rotated within the body. Dislocated tissue with withdrawn from the body via the cannula.
BROACH HANDLE FOR A RASP AND SURGICAL DEVICE COMPRISING SAID HANDLE
A broach handle for a rasp includes a proximal part extending along a first axis between a first portion of the handle and a second portion of the handle, and a proximal part extending partially along a second axis between a third portion of the handle, connected to the second portion, and a fourth portion of the handle, and partially along a third axis between a fifth portion of the handle, connected to the fourth portion, and a sixth portion of the handle connectable to a rasp. The sixth portion of the handle has a connection surface for connecting to the rasp having a normal extending along a normal axis defining a connection axis between the handle and the rasp. A first convex angle is defined between the first axis and the second axis, and a second convex angle is defined between the third axis and the normal axis.
TALAR IMPLANT
Provided is a prosthesis for ankle arthroplasty including a talar dome component configured to be attached to a talus bone. Also provided is a guide instrument for guiding a reamer to prepare a talus to receive the talar dome component.
Circular fixator system and method
A device comprises a base. A support is attached to the base. The support is shaped to receive a calf of a person and adapted to receive a wire or pin for securing a tibia of a person. A foot plate is attachable to the base. The foot plate has a plurality of attached members. The members are configured for receiving at least a first wire or pin to fix a foot of the person relative to the foot plate while the foot plate is oriented normal to a superior-inferior direction of the foot. The foot plate is rotatable relative to the base while the foot plate is attached to the base.
JOINT REPLACEMENT PROSTHESIS WITH TRANS-CORTICAL STEMS
Provided is a novel joint replacement prosthesis that includes a base component, and one or more modular stems. The base component includes a bone-facing surface including one or more stem connectors configured for receiving and forming connections with the one or more modular stems inserted from the bone-facing surface side.
Patient-specific guides for latarjet procedure
Patient-specific guides for the Latarjet procedure, as well as surgical systems and methods of performing the Latarjet procedure to treat glenohumeral instability using such patient-specific guides are disclosed. A patient-specific coracoid guide and a patient-specific glenoid guide may be configured based on preoperatively generated three-dimensional models of the patient's shoulder anatomy. Guides may be configured for coracoid graft preparation and glenoid decortication. The coracoid graft may be placed in the desired position based on three-dimensional (3D) preoperative planning.
ULTRASONIC SPINAL SURGERY METHOD AND ASSOCIATED SURGICAL INSTRUMENT
An elongate ultrasonic dissector-shaver probe has a laterally enlarged head extending distally and transversely from a distal end of a shaft and provided with sets of spiraling ribs. In a disc space preparation procedure, the probe is inserted into a spinal disc between two vertebral endplates, ultrasonic vibratory energy is conducted into the probe, and the probe is manipulated to move the laterally enlarged head in three spatial directions within the spinal disc to thereby disrupt and shred the spinal disc material into fragments extracted from the space, in part by suction and in part by using forceps to pull spinal disc fragments from the operative space or surgical site between the vertebral endplates.
Asymmetric clamp with ultrasonic tissue removal capability
An ultrasonically assisted clamping system and method for extending a spinal support rod system to additional vertebrae of the spine. A clamp assembly and a receptacle assembly securely couple an additional extension rod to an existing spinal support rod. Various embodiments further include an ultrasonic assist for cutting through tissue that may be present in the vicinity of the existing spinal support rods. In some embodiments, the clamp assembly is configured to augment the ultrasonic aspect of the system. The system cuts through and locally removes tissue from and proximate to the spinal support rods where the clamp assembly is to be mounted, without the need for a separate surgical procedure for removing the tissue prior to implantation, thereby providing a secure clamping of the newly implanted extension rod to the existing base spinal support rod.
SURGICAL INSTRUMENTS AND METHODS
A cement restrictor inserter instrument (130) comprises an inserter (131) having a handle (132) at a proximal end, a cement restrictor attachment formation (137) at a distal end for releasably attaching a cement restrictor (150), a shaft (136) extending from the proximal end to the distal end and a stop (138) on the shaft and between the proximal end and the distal end; and a body (140) having a shape corresponding to the shape of an orthopaedic prosthetic implant, a spacer (142), a visible depth guide feature (190) and a releasable attachment mechanism by which the body is releasably attachable to the shaft, and wherein the spacer is configured to position the visible depth guide feature at a fixed position relative to the inserter when the spacer abuts the stop corresponding to a target cement restrictor position when the visible depth guide feature is aligned with a feature of a bone of a patient in which the cement restrictor is to be inserted.
INSERTER WITH A TELESCOPING REFERENCE FOOT
Disclosed herein are reference feet for inserters and method of use thereof. The reference feet can include a body, a tine, a first arm, and a first base. The body can have a longitudinal axis and define an engagement fixture oriented parallel to the longitudinal axis and sized to receive a complementary fixture of an inserter. The tine can extend from the body along the longitudinal axis and including a protuberance sized to engage a stop of the inserter. The first arm can extend from the body. The first base can be attached to the first arm and have a planar surface arranged at an angle relative to the longitudinal axis.
