Patent number: 11389177Abstract: A method includes mapping a contoured surface of at least one bone onto a digital model of a resection guide locator using a processor to create a digital model of a customized resection guide locator and manufacturing the customized resection guide locator. The customized resection guide locator includes a complementary surface of the at least one bone and a wall having a shape that is complementary to an outer profile of a resection guide and defining a pocket. A first elongate slot and at least one first hole are positioned within the pocket such that the first elongate slot aligns with a second elongate slot defined by the resection guide and the at least one first hole aligns with at least one second hole defined by the resection guide when the resection guide is received within the pocket of the customized resection guide locator.Type: GrantFiled: May 25, 2020Date of Patent: July 19, 2022Assignee: MicroPort Orthopedics Holdings Inc.Inventors: Michael Carroll, Richard Obert, Paul Stemniski

Methods and tools for hip replacement with superscapsular percutaneously assisted total hip approach
Patent number: 11331204Abstract: 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.Type: GrantFiled: January 7, 2021Date of Patent: May 17, 2022Assignee: MicroPort Orthopedics Holdings Inc.Inventor: James Chow -

Patent number: 10390846Abstract: 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.Type: GrantFiled: May 20, 2014Date of Patent: August 27, 2019Assignee: MicroPort Orthopedics Holdings Inc.Inventor: Brad L.
