The present disclosure relates to a surgical aiming device 1 that prevents a sleeve from being pushed backward or shaken when a drill or a leg screw is implanted after a guide sleeve is mounted on an aiming device. The surgical aiming device includes: a body 20 having an aiming arm 21 and a barrel 22; a guide sleeve 30 disposed at an end of the aiming arm 21 and guiding a nail 10 and a leg screw 12; and a knob 40 for detachably attaching the guide sleeve 30, in which the guide sleeve 30 can be detachably attached in a one-touch type by a guide sleeve attachment/detachment unit 100 installed at an end of the aiming arm. The guide sleeve attachment/detachment unit 100 includes: an operation unit 21a installed at an end of the aiming arm 21; a button 110 installed at the operation unit 21a and partially exposed to the outside; an operation lever 120 being rotated on a rotary shaft by operation of the button 110; and a threaded portion 30a controlled by the operation lever 120 and formed on the guide sleeve 30a.

A hip/shoulder prosthesis includes: a head component; a metaphyseal component; a diaphyseal nail, and a locking device. The head component includes: a front face and rear face; with a bore, and first and second shaped recesses in the rear face. The metaphyseal component includes: a central transverse aperture at an angle to the metaphyseal component's axis; a first end configured for threaded engagement within the bore of the head component; and a longitudinal hole that begins at the second end, transects the transverse aperture and reaches the first end, to receive the locking device. The diaphyseal nail is inserted in the femoral or humeral canal, and includes: fastening apertures that receive corresponding screws for fastening the diaphyseal nail to the femur or humerus; a portion configured to he received within, and engage, the transverse aperture of the metaphyseal component, and a transverse hole configured to receive the locking device.

The invention is directed to a surgical device which is externally used as aiming device that permits accurate placement of surgical wire to mend a supracondylar fracture. The device of the invention decreases operative time, risks of the re-dislocation through continuous manipulation, radiology exposure for both the patient and operation room staff, and to decreases anesthesia duration. It is also directed to surgical use of the device for repair of a supracondylar fracture and to methods for making it.

A subtalar nail implant system, an apparatus and spacer for such a subtalar nail implant system and methods of fusing a subtalar joint of a patient allow for primary and revision arthrodesis of the subtalar joint. The system allows for a more stable fusion construct, compression at the fusion site and immediate weight-bearing.

An arthrodesis nail and nail adapter system having multiple coupling positions includes a bent arthrodesis nail and a nail adapter. The nail has multiple evenly spaced notches. The nail adapter has multiple evenly spaced protrusions corresponding to the notches. An arthrodesis nail adapter and target arm system having multiple coupling positions includes a nail adapter and a target arm. The nail adapter has a predetermined coupling orientation with a bent arthrodesis nail. The target arm has multiple coupling positions with the nail adapter. The arthrodesis nail and nail adapter system allows rotation of the bent nail for reduction of ankle deformity.

A guide sleeve for use in anchoring a fixation member to an intramedullary nail and to bone includes a sleeve body that is elongate along a central axis and has an internal surface that defines a bore extending along the central axis to a distal end of the sleeve body. The sleeve body also defines a plurality of guide channels that are each recessed radially outwardly from the internal surface and each include a helical proximal portion and a linear distal portion that extends from the helical proximal portion toward the distal end. The linear distal portion is parallel with the central axis. The guide channels are configured to receive respective complimentary followers of an instrument for driving the fixation member through the bore and subsequently through the intramedullary nail and into the bone.

Intramedullary nails, systems, and methods. The intramedullary nail may include a generally elongate body extending from a first, distal end to a second, proximal end. The distal end may include one or more openings configured to receive one or more bone anchors that extend transversely through the distal end intramedullary nail, and thereby configured to secure the distal end of the nail. The proximal end may also include one or more openings configured to receive one or more bone anchors that extend transversely through the proximal end of the intramedullary nail, and thereby configured to secure the proximal end of the nail. In some embodiments, the proximal opening may contain one or more relief cuts.

Fixation guide devices and methods for positioning and inserting an intramedullary nail are disclosed. The fixation guide devices include a frame with a first end and a second end, a compression device removably coupled to the first end of the frame, and the intramedullary nail secured to a nail attachment apparatus of the frame. An intramedullary nail including a body with a fastening end, a closed end, and at least two openings is also disclosed. A compression device includes a compression member, a knob, and a bolt secured in the knob and rotatably engaging the compression member is also disclosed. An alignment guide is disclosed and includes a base member, an alignment member, and a fixation guide. A method of inserting an intramedullary nail into two bones for fixation of the two bones is also disclosed.

Disclosed is a method for providing visual guidance in a medical surgery. The method comprises registering, within a virtual assistance device having a combination of a virtual medical implant, an Intra-Medullary (IM) nail model and a virtual insertion handle model, each of a physical IM nail implant and a physical insertion handle. Further, a physical drill gun is registered within the virtual assistance device having a drill gun model. Further, coordinates of the one or more holes on the physical IM nail implant are registered within the virtual assistance device. The physical IM nail is inserted into a target. The virtual impression of the physical drill gun is aligned over the one or more holes based on the coordinates. Further, one or more surgical steps are performed by the physical drill gun based on the aligning.

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.
