Description

Surgical guiding bone plate

The present invention relates to a surgical guiding bone plate, and more particularly to a surgical guiding bone plate device for dental, orthodontic and facial shaping surgery.

One of the conventional Orthognathic surgery is to correct the structural and developmental problems of the ankle and face or to improve sleep apnea, TMJ disorders, and skeletal problems. Improper, or other surgery that is not easily done with orthodontic dentition correction; usually this procedure is often used to treat patients with congenital cleft lip and palate. When the doctor performs a correct operation for the patient, the original osteophyte site needs to be cut and adjusted, and then the bone plate and the bone nail are used to join the bone and shape, and the doctor usually performs the surgery again to facilitate In order to fix the ankle or bone, it is often necessary to use medical metal plate, screws, bone nails, stainless steel wire and other materials to fix and shape the structure of the patient's ankle and face, but the conventional products do not have It is designed to completely conform to the surgical incision site guiding plate or fixing plate of the bone. Usually, when the surgeon performs the operation, it is often necessary to perform the cutting operation by hand with the doctor's experience value. This conventional surgery experience may be due to the doctor's operation time. When the length of the experience or the doctor's operating part is deviated or distorted, it is easy to cause the patient to follow a fixed When the bone plate corrects the bone, it will not be able to reach the correct bite position in the future or cause a lack of bite misalignment such as excessive bite.

A customary Taiwan patent 201313207 "for combination upper jaw correction a hinged fastening device comprising: a first foot plate comprising a plurality of first foot plate bodies configured to be attached to a first bone portion; a second foot plate comprising a set of second footboard portions configured to be attached to a second bone portion; and an engagement element coupled between the first and second footplate body portions, the engagement member including a defining one a hinge of the pivot axis, the first foot plate body being passively rotatable relative to the second foot plate body about the pivot axis in response to a force applied to the second foot plate body, the former patent system Rotating with a hinge to adjust the angle of engagement between the plate and the bone still fails to provide a correct guiding position and subsequent precise drilling of the fixed bone plate. The previous case does not really solve the problem of the accurate alignment of the bone plate and the human skeleton. Position and firmly combine bone features.

A customary Taiwan patent 201404364 "Gentium correction anchor module And the orthodontic plate and the surgical guiding device, comprising a two-nail nail and an orthotic plate, each of the bone nails having a bare segment and an implanting segment, wherein the bare segment of the bone nail is provided with a first twisting portion a locking portion and a second locking portion, the first locking portion is adjacent to the implanting portion of the bone nail, and the circumferential surface of the first locking portion is non-circular, and the fastening portion is located at the first portion Between a spinlock portion and a second spin lock portion; the correcting plate has a bridge portion connected thereto, a positioning segment and a turn buckle segment, the bridge segment being located between the positioning segment and the buckle segment, the bridge segment Having at least one hook portion, the The segment and the buckle segment are respectively fastened to the fastening portion of the two nails. The gingival correction anchoring module can guide the two bone nails into a proper position of the tibia through a surgical guiding device, so that the correcting plate overlaps the two nails, but the patented orthodontic plate and bone The nail is unable to adjust the position of the knife and does not provide a fixed angle of the bone plate and accurately engages the bone. It may still cause the patient to be unable to properly bite or excessively bite in the future.

Therefore, there is a need to propose a surgical guiding bone plate that can be used for Dental, orthodontic and facial surgery, the doctor can use the operation to guide the bone plate to accurately provide facial squat and bilateral cheek bone surgery in the guiding operation and accurate positioning of the hole to solve the problem of conventional sputum surgery only It is possible to confirm the cutting position and drill the calibration work with the doctor's experience value.
