Problems solved by technology

There are two types of implants in the prior art, one is the use of simple threaded implants, but because the support only depends on the implants, the stability is poor, and it takes a long time (6 months to 1 year) to wait after the operation. Put the artificial organ on, otherwise it will loosen and even cause the operation to fail
Another type of planting device uses a quincunx-shaped reinforcing plate, and a mounting hole is set at each protruding end of the reinforcing plate, which is fixed with bone screws. This kind of connection cannot form a relatively firm osseointegration, and the reliability is poor.

Abstract

The present invention relates to a kind of cranio-maxillo facial planting system and ccorollary surgical equipment. The present invention features that the planting system includes one implant with external thread in the root part and neck part, cut cone in the end of the root, positioning cone in the top and spanner step with central screw hole; one reinforcing board with installing holes and one ring for tissue to penetrate, notch corresponding to the spanner step and flanges; one tissue penetrating screw; one base stage with notch and flanges; one base stage screw penetrating the flange in the base stage for connecting to the screw hole in the tissue penetrating screw; and one rod with one end welded to the inner hole of the base stage and the other end connected to other base stage. The present invention has fast growth and combination of bone in the implanted position, high surgical operation safety, wide application range, and short time from operation to wearing artificial organ.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a craniomaxillofacial implant system and its matching surgical instruments. Background technique [0002] Cranio-maxillofacial implant is an implant surgery to repair and reconstruct craniofacial defects (such as ears, nose, teeth, upper and lower jaws, craniofacial organs) caused by congenital, accident, war injury and tumor. In addition to using conventional surgical instruments, a special implant system and surgical instruments used with the implant are also required. There are two types of implants in the prior art, one is the use of simple threaded implants, but because the support only depends on the implants, the stability is poor, and it takes a long time (6 months to 1 year) to wait after the operation. Put the artificial organ on, otherwise it will loosen and even cause the operation to fail. Another kind of planting device is to adopt a kind of quincunx-shaped reinforcing plat...
