Abstract:
A medical device system for implantation in a hip joint for providing at least one artificial hip joint surface for a patient, the medical device system comprising an artificial caput femur surface (45); or an artificial acetabulum surface (65) being at least partly bowl-shaped. The system has a largest cross-sectional distance being variable such that the medical device system can be inserted through a hole (18) in the pelvic bone (9), from the abdominal side of the pelvic bone, the hole having a diameter smaller than said largest cross-sectional distance. Further the artificial acetabulum surface (65) comprises at least two parts (45', 45", 46, 53a, 53b, 54b, 56, 63, 64a,) which are adapted to be interconnected to form an interconnected medical device when in use.

Abstract:
Milling device for prosthetic surgery comprising a milling tool (11) rotating about a milling axis (R), and a handling body (14). The handling body (14) is provided with a drive rotating rod (22) which develops along a longitudinal axis (Z) of linear rotation and is connected to the milling tool (11) in order to make the milling tool (11) rotate about the milling axis (R).
Abstract:
A flat reamer (200) has a reamer shaft (270) and two opposite blade wings (220, 221). The blade wings have a proximal reamer area (202) with first cutting areas (240-241) and second cutting areas (250-252) intermittently separated by first recesses (245-246) and second recesses (255-256), respectively. The cutting areas have variable sharpness with the highest sharpness at the center and decreasing to the outside.
Abstract:
The invention concerns a cranial drill system (100, 200, 300, 400) comprising one or more surgical drill elements (102, 202, 302, 402) for drilling into the brain. The invention also concerns a cranial drilling system (1200, 1300) comprising a surgical drill element for drilling into the skull (110, 210, 310, 410, 1210, 1310) and an element (102, 202, 302, 402, 1202, 1302) for penetrating the dura. The surgical drill element (310, 1310) may comprise a profile that forms an opening (153, 1153) in the skull (151, 1151) having a narrower diameter portion (153a, 1153a) and a wider diameter portion and the piercing element (302, 1302) may be arranged to be a close fit in the narrower diameter portion (153a, 1153a) of the opening. The invention also concerns a cranial drill system comprising a guiding element (210, 1210) to be located in a hole (153, 1153) formed through the skull (151, 1151) and a piercing element (202, 1202) for piercing the dura. The guiding element (210, 1210) may have a passageway or channel (220, 1220) therein for receiving the piercing element (202, 1202) such that the piercing element (202, 1202) is movable relative to the guide element (210, 1210) to pierce the dura.
Abstract:
Surgical instruments and procedures are disclosed that enable the injection of an optimal amount of curable resin and/or the placement of an internal fixation device in an intramedullary canal of a fractured bone. The disclosed instruments and procedures enable a surgeon to clear a portion of the canal of cancellous bone and marrow across the fracture site without damaging the cortical wall.
Abstract:
A surgical trabecular tool for manipulating or removing bone tissue is disclosed which comprises a tool body, at least one cutting element provided on said tool body, said cutting element comprising a number of cutting edges arranged on said cutting element, wherein said tool body is formed at least in part by a trabecular internal structure including a plurality of material struts forming a regular or irregular lattice structure which supports and connects the cutting elements.
Abstract:
Provided herein is an adaptor for modifying the operation of a surgical bone-tool, comprising: a housing having a distal end and a proximal end coupled between a chuck and an operating bit of said tool, such that force generated by a motor of the tool is delivered to the operating bit through the adaptor; a clutch, contained in the housing, having an engaged and a disengaged configurations, respectively interconnecting and disconnecting the chuck to the operating bit; the clutch automatically disengages in response to an electric current, causing a cutoff of the force delivery; wherein the housing comprises a proximal fastener, sized and shaped to connect with the operating bit and a distal fastener, sized and shaped to connect with the chuck.
