Embodiment Construction

[0050] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0051] The technical ideas of the present invention aim at the general technical defects of the traditional acetabular navigation template—the acetabular navigation template is first fixed in the acetabular fossa during the operation, then positioned and punched, and then the acetabular navigation template is removed, and finally the acetabular navigation template is targeted. Perform acetabular grinding.

[0052] Aiming at the defects of the existing technology, an acetabular navigation guide that does not require positioning, drilling, template removal and other procedures during the operation, and can effectively improve the efficiency of the operation and the accuracy of the installation of the prosthetic acetabulum.

[0053] The specific technical details of the technical solution of the present invention are as follows:

Abstract

The invention discloses an acetabulum navigation guiding plate designed by 3D printing. The plate comprises a navigation guiding plate, a navigation angle device and a Kirschner wire, wherein the navigation guiding plate is designed according to CT three-dimensional data of a patient to form a navigation guiding plate which can be clamped on an acetabulum rim; and meanwhile, the navigation guidingplate is fixed on the acetabulum rim through the Kirschner wire; and the navigation angle device is matched with the navigation guiding plate and an acetabulum polishing file to guide and correct theacetabulum grinding angle and realize accurate grinding of the acetabulum. The acetabulum navigation guiding plate does not need to be removed in the acetabulum polishing process, and the acetabulumcan be polished more accurately and easily through the navigation angle device, so that the placement angle accuracy of an acetabulum prosthesis is more accurate than that of the traditional technology; and compared with the traditional template, the operation time and the bleeding amount are effectively reduced due to omitting relevant links such as hole punching of a fixed point of the acetabulum, axis positioning hole punching, removal of the template and the like.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to an acetabular navigation guide designed by 3D printing, a preparation method and a use method. Background technique [0002] The total joint is composed of the socket and the femoral head. Total joint replacement surgery is to replace the diseased total joint with an artificial total joint. The acetabular debridement is required in total joint replacement surgery, and the debridement process includes soft tissue resection, osteophyte resection, and acetabular rasps. Mortar filing is to use the mortar file to deepen and enlarge the mortar to form a mortar bed that is easy to install the acetabular cup (artificial mortar), the depth, width of the mortar bed and the coincidence of the axis of the mortar bed and the patient's mortar axis Degree is an important factor affecting the stability of acetabular cup installation. Therefore, it is required to use the anteversion a...
