Description
Technical Field
The invention relates to a bone plate fixing device, in particular to a bone plate fixing device for dental, jaw correcting and facial cosmetic surgery.
Background
An orthodontics (orthodontics surgery) is known, which is performed to correct the structural and developmental problems of the jaw and face, or to improve malocclusions due to sleep apnea (sleep apnea), temporal mandibular joint dysfunction (TMJ disorders), skeletal problems, or other orthodontic problems that are not easily accomplished with dental appliances. This procedure is often used to treat patients with congenital cleft lips. When a surgeon performs a maxilla surgery on a patient, the original bone needs to be cut and adjusted, and then the bone is shaped by a bone plate and bone nails to join the bone. Usually, a doctor often needs to use medical metal bone plates, screws, bone nails, stainless steel wires, etc. to fix and shape the jaw and face of a patient during an operation. The known metal bone plate structure does not have a standard product which can be completely attached to bones, and when a doctor performs an operation, the locking bone plate is often processed by hands with experience to adjust the angle of the locking bone plate, so that the operation time is too long, and the operation difficulty is increased. The failure of the bone plate to lock the bone may cause problems such as improper occlusion, over-occlusion, and malocclusion at a later date.
One known taiwan patent 201313207, "hinged fixture for use in combination with upper jaw correction", includes: a first footplate including a first footplate body portion configured to be attached to a first bony portion; a second footplate including a second footplate body portion configured to be attached to a second bony portion; and a coupling assembly coupled between the first and second foot plate portions, the coupling assembly including a hinge defining a pivot axis about which the first foot plate portion is passively rotatable relative to the second foot plate portion in response to a force applied to the second foot plate portion. The prior patent is a rotating hinge and then adjusting the joint angle of the plate body and the skeleton, but still can not solve the problems of accurate alignment, stable combination and the like between the existing bone plate and the skeleton appearance characteristics.
One known taiwan patent 201404364, the die set for correcting and anchoring teeth and jaw, and the correction plate and surgical guiding device thereof, includes two bone nails and a correction plate, each of the bone nails has an exposed section and an implanted section connected, the exposed section of the bone nail is provided with a first twist-lock part, a fastening part and a second twist-lock part, the first twist-lock part is adjacent to the implanted section of the bone nail, the circumferential surface of the first twist-lock part is non-circular, the fastening part is located between the first twist-lock part and the second twist-lock part; the correcting plate has a bridging section, a positioning section and a screwing section connected with each other, the bridging section is located between the positioning section and the screwing section, the bridging section is provided with at least one hooking portion, and the positioning section and the screwing section are respectively buckled on the buckling portions of the two bone nails. The anchoring module for correcting the tooth jaw can lock the two bone nails at proper positions of the jaw bone through the operation guiding device, so that the correcting plate is lapped with the two bone nails. However, the correction plate and bone screw of the prior patent cannot adjust the angle of the bone plate so as to accurately engage with the bone, and may cause problems of incorrect occlusion, excessive occlusion, malocclusion, etc. of the patient in the future.
A known Taiwan patent I398241, a dental palatal jawbone micro-implant, comprises a plate body and a correction fitting, wherein the plate body is placed in the keratinized epithelial tissue of the upper palate of a corrected person, a first locking component and a second locking component respectively penetrate through a first locking hole and a second locking hole formed at two ends of the plate body to lock the plate body on the upper palate, and a third locking component penetrates through a fourth locking hole formed on the correction fitting and a third locking hole formed on the plate body to lock the correction fitting on the upper palate. However, the plate body of the prior patent still cannot solve the problems of accurate alignment and stable combination of the existing bone plate and the bone morphology characteristics.
Therefore, there is a need for a bone plate for dental surgery, maxilla surgery and facial surgery, which can be precisely positioned and stably combined with the bone features of human body, so as to solve the problems of the prior art that the bone plate needs to be manually processed or the locking angle needs to be adjusted by a doctor with bare hands.
