  • Patent number: 10729558
    Abstract: Illustrative methods and systems for customizing a pre-manufactured acetabular shell to a specific patient are described herein. An illustrative method can include positioning a provisional shell at an acetabulum of the patient, the provisional shell having a plurality of selectable openings. The method further including marking, based on the assessing of the bone, a patient-matched hole location on a provisional liner that corresponds to one of the plurality of selectable openings in the provisional shell. With the provisional liner marked, the method can further include removing the provisional liner from the provisional shell and positioning the provisional liner in the pre-manufactured acetabular shell that is to be implanted in the patient. Using the provisional liner as a guide, the method can include forming a hole in the acetabular shell corresponding to the marked patient-matched hole location on the provisional liner.

  • Patent number: 10660658
    Abstract: The invention provides a surgical tool driver having a proximal end having a coupling and a distal end comprising a surgical tool connector having a release sleeve for disconnecting the surgical tool. The surgical tool connector further includes a locking member having a locking head adapted for coupling with at least one surgical tool. The locking member is slidingly disposed and at least substantially enclosed within the center of the driver and closely interfaces therewith so as to minimize seams, gaps or openings. The locking member has an axial range of motion which assures that between an unlock and lock position, the locking head is embedded in the driver in the unlock position and then extends axially outwardly, in snug juxtaposition with the driver, to a lock position which is capable of locking a surgical tool to the tool driver in a manner so as to avoid the exposure of a significant seam, gap or opening during activation and so helping prevent debris and/or bone chips from entering the driver.

  • Patent number: 8828008
    Abstract: Devices, systems and methods for performing arthroscopic evaluations and procedures in and near the hip joint are provided. An arthroscopic assisted arthroplasty system is useful in the treatment of arthritic hip conditions, conserving healthy tissue, and limiting iatrogenic injury associated with traditional surgical exposures. A guide wire system employing retrograde and antegrade reamers along the femoral neck is useful in anatomic placement of instrumentation without formal hip dislocation. Fluoroscopy and computer assisted navigation enhance the system, methods, and apparatus. Acetabular and femoral collapsible prosthetic forms are useful in arthroscopic assisted placement. The devices, systems, and methods are effective to assist an operating surgeon in the addressing mild to moderate arthritic conditions of the femoral head and acetabulum where tissue conservation and surgical exposure morbidities should be limited.

  • Patent number: 8740907
    Abstract: A short main incision and portal incisions at portal positions strategically displaced from the main incision are provided in a patient's hip. One portal incision (acetabular portal) provides for a disposition of reamers in the patient's acetabulum to shape the acetabulum. A cannula is inserted through the portal incision to the acetabulum and the successive reamers of progressive size are inserted into the acetabulum through the main incision to progressively size and shape the acetabulum. An approximately hemispherical acetabular component is then disposed in the prepared acetabulum to provide for hip rotation relative to the femoral component. The other portal incision (femoral portal) provides for insertion into the patient's hip of a member for driving the femoral stem into a cavity in the patient's femur. The provision of the short main incision and the portal incision minimizes the patient's loss of blood, tissue trauma, length of operating time and patient recovery time.

    Abstract: A hip replacement method in which includes making an anterior incision and a lateral incision proximate the hip joint. The method next includes preparing a femoral passage directed along an axis of the femoral neck of the femur. An acetabulum reamer coupled to a femoral elongate element installed in the femoral passage is used to ream the acetabulum. The femoral head is prepared using a tool coupled to a femoral elongate element installed in the femoral passage. An acetabular prosthesis is then installed using a femoral elongate element installed in the femoral passage. A femoral prosthesis is installed using a femoral elongate element installed in the femoral passage. All of the foregoing steps are performed without dislocating the hip joint.

  • Patent number: 8679125
    Abstract: A method of performing hip surgery with a robotic guided system on a patient with femoral acetabular impingement can include identifying the femoral acetabular impingement on the patient. Data related to a proximal femur and an acetabulum of the patient is acquired. A three-dimensional model of at least one of the patient's proximal femur and acetabulum is created based on the data acquired. A location and amount of bone to be removed is determined. Dynamic movement limits of a cutting tool associated with the robotic guided system is set based on the determination. The determined bone of at least one of the proximal femur and acetabulum is removed with the tool while being inhibited from moving the tool outside of the dynamic limit by the robotic guided system.
