Abstract
The invention discloses an assembled wing-reinforced repairing acetabular cup prosthesis. The prosthesis consists of an acetabulum 1, a reinforcing wing 2 and a connecting bolt 3. The reinforcing wing has multiple shapes and specifications for the clinical use, and is applicable for different types of bone defects. The reinforcing wing and the acetabulum are jointed and fixed in the following ways: 1, the reinforcing wing and the acetabulum are assembled through a dovetail groove or a T-shaped groove or a rectangular groove and fixed by the connecting bolt; 2, the reinforcing wing and the acetabulum are tightly pressed by taper fit and then fixed by the connecting bolt; and 3, the reinforcing wing and the acetabulum are connected and fixed through a plurality of connecting bolts. Granular bone can be implanted into a gap between the acetabular cup and the acetabular bone bed so as to enhance the stability of the side where a hip joint prosthesis replaces acetabulum through bone healing.
Description
Technical field
The present invention relates to a kind of acetabular cup prosthesis, be applicable to that specifically acetabular bone deformity or the bone that causes because of first hip replacement dissolve, the damaged acetabular cup prosthesis that need overhaul of bone.
Background technology
Artificial hip joint replacing has been a kind of very sophisticated operation at present, adds the fast development of China market economy in recent years, prosthetic replacement's amount for surgical cumulative year after year.Be subject to reason in many ways such as prosthetic material, prosthese fixed form, interface wearing and tearing, surgical technic, the artificial joint life-span was generally about 20 years.Must carry out twice replaced operation after the prosthese failure.This moment, patient's acetabular bone side often because of the prosthese wear particle causes the bone dissolving, caused segmental or volume bone damaged.Exist the multiple acetabular cup of overhauling on the market, but because the damaged multiformity of bone can not satisfy clinical needs fully.If there is not suitable prosthese, must strengthen the stability of acetabular bone in the operation by the mode of bulk allograph bone bone grafting, this has just increased allograph bone and has been absorbed risk with prosthetic loosening.
Summary of the invention
The assembly type wing that the purpose of this invention is to provide a kind of combining,, facilitating operation damaged applicable to dissimilar bones strengthens overhauling acetabular cup prosthesis.
For achieving the above object, the present invention adopts following design:
A kind of assembly type wing is strengthened overhauling acetabular cup prosthesis, and it forms (as Fig. 1) by acetabular bone 1, strengthening wing 2 and attachment screw 3.Strengthening wing is processed or the preparation of cobalt chrome molybdenum foundry goods by titanium alloy powder electron beam melting method or titanium alloy forging, and multiple shape, plurality of specifications is arranged for clinical use (as Fig. 7).There are some apertures on the surface of strengthening wing, and particulate cancellous bone 6 passes through when allowing impaction bone grafting, makes strengthening wing and particulate cancellous bone form interlocking.Strengthening wing combines fixed structure with acetabular bone have following 3 kinds:
1. as shown in Figure 4, with the bonded side of acetabular bone dovetail guide or T type guide rail or rectangular guideway are arranged on the strengthening wing.Design has some dovetail grooves or T type groove or rectangular channel on the acetabular bone, and is not groove, guarantees that strengthening wing can not skid off track.Fig. 2 is multiple-grooved distributed architecture figure, curved distribution and certain angle 8 is arranged.Fig. 3 is single cavity distributed architecture figure.Strengthening wing and acetabular cup are fixed by dovetail groove or T type groove or rectangular channel assembly and with attachment screw.
2. as shown in Figure 5, a conical bore is arranged on the strengthening wing, a circular cone is arranged on the acetabular bone, strengthening wing and acetabular bone compress by taper fit, and the reuse attachment screw is fixed.
3. as shown in Figure 6, strengthening wing and acetabular bone are connected and fixed by a plurality of attachment screws.
Have a closed pore to collude 7 on the acetabular cup, there are some screw holes on the surface, catches on the pelvis closed pore with closed pore earlier during installation, and reuse cancellous bone screw 5 is fixed on acetabular cup on the acetabular bone bone bed 4.Defect is implanted particulate cancellous bone, strengthens the stability of hip prosthesis displacement acetabular bone side by self sclerotin healing.(as Fig. 8, shown in Figure 9)
Advantage of the present invention is:
1. strengthening wing has plurality of specifications for clinical use, at utmost satisfies clinical demand;
2. strengthening wing and acetabular bone assembly are convenient and simple, simplify operation process.
3. than the bulk bone grafting, the invention provides better support, and do not have the absorbed risk of bulk bone grafting.

The specific embodiment
A kind of assembly type wing is as shown in Figure 1 strengthened overhauling acetabular cup prosthesis, and it is made up of acetabular bone 1, strengthening wing 2 and attachment screw 3.Strengthening wing 2 and acetabular bone 1 assembly in several ways, and fixing with attachment screw 3.Can select the strengthening wing of different size damaged in the operation to adapt to dissimilar bones.Collude 7 with closed pore and catch on the pelvis closed pore, reach some other defect between the strengthening wing and can implant particulate cancellous bone 6, with some cancellous bone screws 5 acetabular cup is fixed on the acetabular bone bone bed 4 at last by impaction bone grafting.
