SYSTEMS AND METHODS FOR ALIGNING SURGICAL DEVICES
A system for targeting a feature on a surgical device, includes a shape sensing element coupled to an interrogator and operable to provide information to related to said portion's position in a reference frame in communication with the targeted feature. The interrogator is operable to poll the shape sensing element for information related to said portion's position in the reference frame. A surgical tool is coupled to the targeting system in communication with the shape sensing element. The data processor is operable to communicate with the interrogator to output position information of the portion of the shape sensing element with respect to a calibrated position, defined as the position of the portion of the shape sensing element in the reference frame when the guide axis is aligned to the targeted feature. A display provides the user visual information comparing the position of the tool to the targeted feature.
IMPLANT FOR FUSING AT LEAST TWO BONE COMPONENTS AND METHOD OF FUSING BONE COMPONENTS USING THE IMPLANT
An implant for fusing at least two bone components and method of using the implant. The implant has a body with first and second anchoring portions. The first anchoring portion has a stem configured to be directed to within a first bone component and is further configured to cooperate with at least a first fastener usable to fix the stem in an operative position relative to the first bone component. The second anchoring portion is configured to overlie at least a second bone component at a placement location at which bone has been strategically removed and is further configured to cooperate with at least a second fastener usable to fix a part of the second anchoring portion to the second bone component with the second anchoring portion in an operative position.
Surgical instrument mounted display system
A surgical instrument assembly may include a processor, a surgical instrument configured to operate on an anatomical structure, and a display coupled to the processor and attached to the surgical instrument. The processor can be configured to determine a position of the medical imaging device, from which the medical imaging device can generate an X-ray image that includes holes of an intramedullary nail shown as circles, for instance perfect circles. In an example, the processor identifies the intramedullary nail, so as to determine an intramedullary nail identity, and determines the position of the medical imaging device based on a portion of at least two locking holes of the intramedullary nail and based on the intramedullary nail identity.
APPARATUS AND METHODS FOR TREATMENT OF A BONE
Apparatus and methods for treatment of a bone. The apparatus may include an implant. The implant may include an implant tail and an implant head configured to expand, inside the bone, from a collapsed state to an expanded state. The apparatus may include an intramedullary rod defining a central longitudinal rod axis. The intramedullary rod may include a guide segment configured to guide the implant head into the bone and support the implant tail. The intramedullary rod may include an elongated extension member spaced radially apart from the central longitudinal axis. The extension member may be configured to provide clearance for the implant head as the implant head is advanced, in the collapsed state, into the bone. The extension member may be configured to provide clearance for the implant head in the expanded state.
A DEVICE AND METHOD FOR FIXATION OF BONE FRAGMENTS IN AN OSTEOTOMY PROCEDURE
The present disclosure relates to a device and method for the fixation of bone fragments in an osteotomy procedure. The device includes a first screw including a shank and an external thread for cortical fixation in the bone body fragment and an opening extending transversely through the shank. The device also includes a second screw including a shank and an external thread for cortical fixation in the bone head fragment for relative fixation of the bone body fragment and the bone head fragment. The shank of the second screw being locatable within the transverse opening of the first screw. The disclosure also relates to a jig mountable to the first screw and including one or more guides to align with the one or more transverse openings through the first screw.
Systems and methods for intramedullary nail implantation
Intramedullary nails, aiming guide assemblies, and methods. The aiming guide assembly can include an aiming guide having a collet and a connection bolt configured to engage a connection bolt driver. The connection bolt may be self-retaining and engage with the connection bolt driver in a manner to prevent unintentional disengagement.
Flexible guide for application of bone plates
Embodiments herein employ a flexible orthopedic alignment guide for surgical implantation of flexible bone plates. Specifically, the alignment guide is designed to be used in conjunction with flexible bone plates whereby flexible sections of the alignment guide aid in alignment of drill bits and fasteners with the fastener holes of the bone plate. The flexible guide is designed to flex in a similar manner to the bone plate, thus maintaining positive engagement without compromising hole alignment.
Cannulated nail extractor
A cannulated nail extractor including an extractor having a proximal end for connecting to an extraction device, a distal end opposite the proximal end, and a connector extending from the distal end. The cannulated nail extractor further includes an engagement wire having an enlarged proximal end configured to engage the extractor and an enlarged distal end configured to engage a distal end of the cannulated nail. The cannulated nail extractor further includes a positioning wire for insertion into the cannulated nail for urging the enlarged distal end of the engagement wire into engagement with the distal end of the cannulated nail, whereby exerting an extraction force on the extractor produces extraction force by engagement of the enlarged distal end of the engagement wire on the distally facing end of the cannulated nail.
INTEROPERATIVE AIMING ARM
In one embodiment, a targeting guide is formed by aligning an axis of a cutting instrument with a bone-anchor fixation hole of an intramedullary nail. The cutting instrument is inserted through the bone-anchor fixation hole such that the cutting instrument is in contact with a guide body of a targeting guide, where the targeting guide is supported relative to the intramedullary nail such that the guide body is spaced outwardly from at least a portion of the intramedullary nail along a radial direction. The cutting instrument is then driven through the guide body so as to form an alignment aperture in the targeting guide. The alignment aperture has a central axis that is aligned with the bone-anchor fixation hole.
2D-IMAGE GUIDED ROBOTIC DISTAL LOCKING SYSTEM
A 2D image-guided surgical robot system for distal locking operations includes surgical image acquisition equipment, a robot arm, a robot end effector attached to the robot arm, and a remote operation workstation. To perform a distal locking operation, the position of the image acquisition device is adjusted to obtain a round outline of a lockhole in the image. A distortion correction is performed. The position of the target lockhole is assigned by a user through the GUI of the remote operation workstation, and the remote operation workstation calculates a robot motion quantity using image feedback control law and moves the robot accordingly. The “image-and-move” procedure is repeated several times until the drill guide is accurately aligned to the lockhole, then the distal locking operation is accomplished by first drilling a guide hole using a guide wire through the drill guide, and then screwing a locking screw through the guide hole.
