A surgical instrument includes a body having a proximal end and a distal end and defining a lumen extending from the proximal end to the distal end along an axis, the distal end configured to abut an implant, and an anchor rod disposable within the lumen of the body for contacting the implant to secure the implant at the distal end of the body. When the anchor rod is disposed within the lumen of the body in a working configuration, the anchor rod is connected to the body at the proximal end of the body and at the distal end of the body to substantially fix the anchor rod from moving along the axis of the lumen. The body includes a handle, a shaft extending distally from the handle, and a torque limiting mechanism.

A bone cement delivery system including a mixer, a reservoir for holding bone cement, a cannula that is connected to the reservoir and through which the bone cement is delivered into living tissue. A plunger that is advanced by a drive assembly, pushes the bone cement out of the delivery tube into the cannula for discharge from the cannula. A valve is located upstream of the cannula. A control unit regulates both drive assembly and the setting of the valve. The control unit is configured to, when deactivating the valve so as to stop the advancement of the plunger, close the valve. The closing of the valve reduces the extent to which the bone cement, which is under pressure continues to flow into and be discharged out of the cannula.

A method of treating a hip joint of a human patient is disclosed. The method comprises the steps of: inserting a needle or a tube like instrument into the patient's body, using the needle or tube like instrument to fill a part of the patient's body with gas and thereby expanding a cavity within said body, placing at least two laparoscopic/arthroscopic trocars in said cavity, inserting a camera through one of the laparoscopic/arthroscopic trocars into said cavity, inserting at least one dissecting tool through one of said at least two laparoscopic/arthroscopic trocars, dissecting an area of the pelvic bone on the opposite side from the acetabulum, creating a hole in said dissected area, said hole passing through the pelvic bone and into said hip joint of the patient, and providing said medical device to the hip joint, through said hole in the pelvic bone of the patient.

A mould adapted to be introduced into a joint of a human patient for resurfacing at least one carrying contacting surface of said joint is provided. The mould is adapted to receive material for resurfacing at least one carrying contacting surface of said joint. The mould is further adapted to be resorbed by the human body or melt after having served its purpose.

Devices and methods for tissue and graft procedures are provided that are designed to fail under a certain amount of force, providing sensory feedback that a particular activity may be providing too much stress on a surgical implant. For example, a surgical implant can include a sacrificial element in the form of a filament designed to break when a certain threshold value of force is met or exceeded, while a second filament that has the ability to withstand higher values of force, is able to maintain the repair after the first filament fails. In other embodiments, the sacrificial element includes a filament engagement mechanism associated with a suture anchor configured to fail at a threshold value of force, and a second filament engagement mechanism of the anchor can maintain the repair after the first one fails. Many implants configurations are provided, as are various surgical methods incorporating sacrificial elements.

A magnetic impactor assembly is described herein. The magnetic impactor assembly generally includes a guide receptacle, and an impactor guide magnetically coupled to the guide receptacle to form a magnetic interface therebetween. The guide receptacle is attachable to a surgical device such as a surgical robotic manipulator arm. The impactor guide receives and guides an impactor to permit a user to impact a prosthesis into a bone of a patient in a planned position and orientation. The magnetic impactor assembly reduces the transmission of excessive forces to a patient or the surgical device if an off-axis impaction force is generated on the impactor through the decoupling of the impactor guide from the guide receptacle.

A surgical or arthroscopic method for resurfacing at least one surface of a hip joint of a human patient using a medical device comprising a first sealing member. The hip joint has an acetabulum surface and a caput femur surface and the method comprises the steps of creating at least one hole passing into the hip joint, placing the first sealing member between the acetabulum surface and the caput femur surface, thereby creating a sealed hollow space between the acetabulum and the caput femur using the first sealing member, and injecting a material into the sealed hollow space, and thereby creating an artificial hip joint surface.

A bone fusion method, system and device for insertion between bones that are to be fused together in order to replace degenerated discs and/or bones, for example, the vertebrae of a spinal column. The bone fusion device includes a frame and one or more extendable plates. The bone fusion device is able to be inserted between or replace the vertebrae by using a minimally invasive procedure wherein the dimensions and/or other characteristics of the bone fusion device are selectable based on the type of minimally invasive procedure.

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.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a central ramp, a first endplate, and a second endplate, the central ramp capable of being moved in a first direction to move the first and second endplates outwardly and into an expanded configuration. The fusion device is capable of being deployed down an endoscopic tube.
