An automated laser cutting station for the production of semi-finished components for prosthetic surgery instruments able, in use, to carry out tissue removal processes. Said automated station comprises at least a first automated operator, a laser cutting apparatus, and a control unit. The present invention also relates to a relative method for the production of such a semi-finished component, and to the semi-finished component thus obtained.

The invention relates to an automated punching station for the production of punched components for prosthetic surgery instruments, in particular for instruments able to mill/cut or otherwise carry out tissue removal processes in preparation for, or in the context of, prosthetic surgery operations. The invention also concerns a method to produce said punched components, and a punched component thus obtained.

The invention relates to a robotic working line for the production of cutting bodies for prosthetic surgery instruments, in particular cutting bodies able to milling/cutting or otherwise carrying out tissue removal processes in preparation for, or in the context of, prosthetic surgery interventions, in this case in the orthopaedic field, such as acetabular cutters, patellar cutters, glenoid cutters, rasps, broaches or similar tools, starting from hollow untreated components having at least one external surface and one opposing internal surface. The invention also relates to a working method for the production of cutting bodies for prosthetic surgery instruments and to a cutting body made by means of a robotic working line and in accordance with the method according to the invention.

A system and method for improving installation of a prosthesis which may include assembly of a modular prosthesis. Devices include prosthesis installation tools, prosthesis assembly tools, site preparation systems, and improved power tools used in implant site preparation, the tools including a secondary motion that preferably includes an ultrasonic vibration.

A method of treating a hip joint of a human patient using a pelvic drill comprising a driving member, a bone contacting and an operating device for operating said driving member. The method comprise the steps of cutting the skin of the human patient, dissecting an area of the pelvic bone on the opposite side from the acetabulum, creating a hole in said dissected area using said pelvic drill, said hole passing through the pelvic bone and into the hip joint of the human patient, and providing at least one hip joint surface to the hip joint, through said hole in the pelvic bone of the human patient. In one embodiment the method includes inserting a needle or tube like instrument into the patient's body for filling a part of the patient's body with gas and thereby expanding a cavity within the body.

A minimally invasive hip joint and a joint replacing method are provided. The minimally invasive hip joint includes a threaded rod and a joint body including a plurality of elastic sheets, with their top ends being all disposed at a top end position of the threaded rod, and bottom ends being all movably sleeved on the threaded rod and dispersedly distributed along the circumferential direction of the threaded rod; and the threaded rod is threadedly engaged with a locking component located at the below position of the elastic sheets. The joint replacing method comprises replacing a damaged or undamaged femoral head on a femur with the aforementioned minimally invasive hip joint. When replacing a damaged or undamaged femoral head with the minimally invasive hip joint, it is only necessary to drill at the outer side of the trochanter major and rotate the locking component.

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 end may further include a cross-locking feature, which includes a second bone anchor that interlocks with a first bone anchor, for example, for enhanced bone purchase and bony fixation.

An implantable medical device for implantation in a hip joint is provided. The medical device comprises: at least one artificial hip joint surface adapted to replace at least the surface of at least one of the caput femur and acetabulum. At least one artificial hip joint surface comprises: a positioning hole with at least one opening in said at least one artificial hip joint surface. The hole is adapted to be placed and dimensioned such that the medical device is adapted to be fitted using a positioning shaft and at least partly surround the shaft, for positioning the at least one artificial hip joint surface in a desired position in the hip joint. The hole is adapted to be fitted using the positioning shaft, when the shaft is stabilized and placed in at least one of the femoral bone and the pelvic bone for positioning said medical device inside the hip joint.

A method for implanting a medical device for lubricating a joint in a human body, said method comprising the steps of creating an opening reaching from outside of the human body into the joint, providing an artificial contacting surface to said joint, fixating the artificial contacting surface to the joint, implanting a reservoir in the human body, and lubricating said artificial contacting surface by pressurizing a lubricating fluid contained in said reservoir.

A minimally invasive surgical procedure for replacing a hip joint is provided. A main incision is initiated at a point being a projection of a tip of a greater trochanter and extends proximally about a distance in the range of from 1 cm to 8 cm in line with the femoral axis. An inline capsulotomy is performed, while keeping muscles and posterior capsule intact, to expose the hip joint capsule for accessing the hip joint. The femoral canal is prepared for receipt of a femoral implant. The femoral head is resected and removed out of the acetabulum. A step of acetabular preparation is performed using a retractor comprising two tip rails, each tip rail having a plurality of tines. Related tools, devices, systems and methods are also provided.
