Abstract
This utility model provides a kind of acetabular bone guide plate, it is characterized in that, guide plate comprises in the form of sheets and the body matched at least partially of inner surface and acetabular bone inner surface, body edges is consistent with acetabular labrum form with acetabular bone lower edge acetabular notch, body being provided with and being positioned at hip joint center and the guide pillar running through body, is a centre bore in the middle of guide pillar.This utility model is reasonable in design, and structure is simple, effectively can reduce operating difficulty.
Description
Technical field
This utility model relates to the acetabular bone guide plate used in a kind of operation on hip joint, particularly relates to a kind of application and the acetabular bone guide plate in the total hip replacement of acetabular dysplasia.
Background technology
Acetabular dysplasia can cause the symptom such as the hip arthralgia, dysfunction, now just need to carry out total hip replacement operation, and the factor of most important impact operation success or failure is exactly the accurate placement of prosthese in account in full joint replacement surgery, the particularly placement of mortar cup prosthesis, because acetabular bone position is dark, the shape of pelvis is irregular again, and the orientation of placing to postoperative acetabular component causes certain difficulty.Particularly for original just hypogenetic hip joint, the determination of mortar cup prosthesis position and control are exactly the key point of operation success or failure.
There are many acetabular bone positioners at present, majority is all utilize sour jujube and the osteoplastic plane of shame on ilium to position, but this kind of locate mode apparatus is complicated and doctor operates time be easy to because error makes operation unsuccessful, and hypogenetic hip joint, adopt during the method and more easily occur that location is inaccurate, therefore need the acetabular bone positioner that a kind of patient being more adapted to acetabular dysplasia uses.
Utility model content
The purpose of this utility model is for the problems referred to above, and provide a kind of reasonable in design, structure is simple, reduces the acetabular bone guide plate of operating difficulty.
For reaching above-mentioned mother's, this utility model provides a kind of acetabular bone guide plate, it is characterized in that, guide plate comprises in the form of sheets and the body matched at least partially of inner surface and acetabular bone inner surface, body being provided with and being positioned at hip joint center and the guide pillar running through body, is a centre bore in the middle of guide pillar.
Further, the inner surface of described guide plate is determined by the striograph of patient.
Further, the guide pillar position of described guide plate is determined by the center of rotation that computer is simulated.
Further, described body with acetabular bone lower edge acetabular notch and acetabular labrum for bone mark.
Further, the diameter of the centre bore of the guide pillar of described body is about 3mm.
Further, in the described centre bore of the guide pillar of described body, a metal guide pin bushing can be installed.
Further, described body and described guide pillar one-body molded.
Further, described body and guide pillar are prepared by 3D printing technique.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, acetabular bone guide plate comprises and presents lamellar, and the body 1 that inner surface and acetabular bone inner surface match, the shape of its inner surface confirms according to the CT image data of patient, under the edge of body 1 and human body acetabular bone, incisurae marginalis and acetabular labrum are to coupling, acetabular bone guide plate also has a guide pillar 2, and the position of this guide pillar 2 should be consistent with the center of rotation of human body acetabular bone.The determination of center of rotation relies on computer modeling technique, and by the CT image data of patient input computer, the hip joint center that computer is planned to implement, compares at the center of rotation with preoperative reality, calculates the center of rotation made new advances.The new center of rotation that guide pillar 2 position of guide plate and computer are simulated is coaxial.Guide pillar 2 has a centre bore 3, and the diameter of its centre bore is about 3mm.Centre bore has valgus angle and the top rake of setting, install in the process of guide pillar in order to reduce at centre bore 3, to the wearing and tearing of centre bore, at the central hole location of guide pillar, a metal guide pin bushing 4 can be installed, when metal guide pin bushing 4 is arranged on central hole location, the diameter of centre bore 3 is about 5mm, and guide pin bushing 4 external diameter is consistent with center-hole diameter is 5mm, and internal diameter is 3mm.
When manufacturing guide plate, adopt 3D rapid shaping technique, according to the body 1 of the guide plate set in computer and the shape of guide pillar 2, carry out one printing shaping, printed material is generally high molecular polymer.
When performing the operation, because body 1 is using incisurae marginalis under acetabular bone and acetabular labrum as bone mark, so incisurae marginalis and acetabular labrum under the lower edges of guide plate and acetabular bone are mated, can accurately locate, guide-localization is being followed closely the centre bore through guide pillar, namely determine the center of rotation of acetabular bone, carry out next step acetabular bone process and the installation of mortar cup prosthesis according to the direction of guide-localization nail.
In sum; although this utility model discloses as above with preferred embodiment; so itself and be not used to limit this utility model; the change that those skilled in the art do when should recognize the scope and spirit of the present utility model disclosed in the claim do not departed from appended by this utility model and retouching, within the protection domain all belonging to claim of the present utility model.
