技术领域technical field
本实用新型涉及颌面整形医疗器械技术领域，具体涉及一种下颌骨牵引成骨手术导板。The utility model relates to the technical field of medical instruments for maxillofacial plastic surgery, in particular to a guide plate for mandibular traction osteogenesis.
背景技术Background technique
下颌骨牵引成骨手术是一种临床最常用的矫正颌骨畸形的术式，传统的术式是手术医生在截断下颌骨后，将骨段移动到设计好的位置，然后采用成品的钛合金接骨板进行固定，从而达到改善患者的骨骼畸形的目的。目前市场上成品的钛板虽然具有多种规格，但由于下颌骨是一种形态结构复杂的不规则骨，因此在手术固定过程中，需要外科医师采用手法进行钛板的弯制，以尽量贴合上颌骨表面，达到固定作用。但无论外科技巧如何，都不可能做到钛合金接骨板完全贴合骨骼表面形态，因此在固定过程中，由于内植物与骨骼之间的间隙，在螺丝固定过程中可能导致应力形变作用，使得离断的上颌骨位置产生移动，导致手术效果不精确。Mandibular distraction osteogenesis is the most commonly used surgical method for correcting jaw deformity. The traditional surgical method is that after amputating the mandible, the surgeon moves the bone segment to the designed position, and then uses the finished titanium alloy The bone plate is fixed to achieve the purpose of improving the patient's bone deformity. Although the finished titanium plates on the market have a variety of specifications, since the mandible is an irregular bone with a complex shape and structure, it is necessary for the surgeon to bend the titanium plate by hand during the surgical fixation process so as to fit as closely as possible. Close the surface of the maxilla to achieve fixation. However, no matter what the surgical skills are, it is impossible to make the titanium alloy bone plate fit the surface shape of the bone completely. Therefore, during the fixation process, due to the gap between the implant and the bone, stress and deformation may occur during screw fixation, making The position of the severed maxilla moves, resulting in imprecise surgical results.
