本发明涉及一种可调节弧形导轨式眼眶牵引器，适用于眼眶整复手术的医疗器械。The invention relates to an adjustable arc-shaped guide rail type orbital retractor, which is a medical instrument suitable for orbital reconstruction surgery.
背景技术Background technique
眼眶整复手术的难度大、风险高。目前临床上常用的整复技术有传统截骨骨块重组+自体骨修复和传统截骨骨块重组+人工材料修复。Orbital reconstruction surgery is difficult and risky. At present, the commonly used restoration techniques in clinic include traditional osteotomy bone reorganization + autogenous bone repair and traditional osteotomy bone reorganization + artificial material repair.
目前临床上常用的整复技术存在各自的缺点：⑴传统截骨骨块重组+自体骨修复：术中需多部位截骨，骨块重组固定，手术风险较大，骨块重组塑形欠佳；缺损采用自体肋骨、颅骨外板、髂骨等修复，自体肋骨供量较大，易成活，但吸收率 高，供区出现继发畸形；颅骨外板吸收量少，外形弧度良好，供区不出现继发畸形，但切取困难，骨片充填厚度不足；自体髂骨亦存在取材及塑形困难等缺点，上述自体材料的应用均增加了医源性创伤。⑵传统截骨骨块重组+人工材料修复：多部位截骨创伤较大，常用的人工材料如羟基磷灰石人工骨、多孔聚乙烯高分子合成材料和钛金属材料等，具有一定的生物相容性和可塑性，成形良好，但同时也存在排异反应、感染、囊肿形成和植入物移位等缺点。At present, the commonly used restoration techniques in clinical practice have their own shortcomings: (1) Traditional osteotomy and bone reorganization + autogenous bone repair: multi-site osteotomy is required during the operation, bone reorganization and fixation are required, the operation risk is high, and bone remodeling is not good ;The defect is repaired with autologous ribs, skull outer plate, iliac crest, etc. The autologous ribs have a large amount of supply and are easy to survive, but the absorption rate is high, and secondary deformities appear in the donor site; There was no secondary deformity, but it was difficult to cut out, and the thickness of the bone slice was insufficient. Autologous ilium also had disadvantages such as difficulty in obtaining materials and shaping, and the application of the above-mentioned autologous materials increased iatrogenic trauma. (2) Traditional osteotomy bone recombination + artificial material repair: multi-site osteotomy is more traumatic, commonly used artificial materials such as hydroxyapatite artificial bone, porous polyethylene polymer composite materials and titanium metal materials have certain biological characteristics. Compatibility and plasticity, well-formed, but at the same time, there are disadvantages such as rejection, infection, cyst formation and implant displacement.

Turning the threaded screw drives any one of the inner and outer orbital rim templates fixed with the traction screw to slide laterally.
本发明设计可调节额眶带方向和长度的模式导轨，并在此导轨上连接可用以牵引眼眶内、外侧形态和距离的分段眼眶内、外侧模板，应用牵引成骨技术达到重建眼眶间距离，或改善眼眶内、外侧缘形态以重建眼眶和眼球合适关系的技术效果。The present invention designs a model guide rail that can adjust the direction and length of the frontal orbital belt, and connects the segmented inner and outer orbital templates that can be used to pull the shape and distance of the inner and outer orbits on the guide rail, and uses the traction osteogenesis technology to reconstruct the distance between the orbits , or the technical effect of improving the shape of the inner and outer edges of the orbit to rebuild the proper relationship between the orbit and the eyeball.

Turning the threaded screw drives any one of the inner and outer orbital rim templates fixed with the traction screw to slide laterally.
本实施例中，所述的分段式眼眶缘模板分成4片，包括左、右内侧眼眶缘模板31、32和左右外侧眼眶缘模板41、42，每片眼眶缘模板上均设有牵引螺钉固定槽。In this embodiment, the segmented orbital rim template is divided into 4 pieces, including left and right inner orbital rim templates 31, 32 and left and right outer orbital rim templates 41, 42, each orbital rim template is provided with traction screws Fixed slot.

通常需要先进行手术截骨，将需要移动的眼眶缘和额部相关骨骼截开，根据手术者的设计确定需要移动的眶缘（如内眶缘、外眶缘；单侧或双侧）。Usually, surgical osteotomy is required first to dissect the orbital rim and forehead-related bones that need to be moved, and determine the orbital rim that needs to be moved (such as inner orbital rim, outer orbital rim; unilateral or bilateral) according to the operator's design.
步骤二：调节额眶带模式导轨的长度和弧度Step 2: Adjust the length and radian of the fronto-orbital belt pattern rail

在皮肤外进行。手术截骨后一般的不应期（休息期）为3-5天，其后即可开始进行骨牵引。其方法为：将导轨螺纹死杆中的牵引固定螺钉，依据手术者的设计，逐日移动0.2～0.25mm；移动方向依据术前设计而定。移动距离依据术前设计而定。Taken outside the skin. The general refractory period (rest period) after surgical osteotomy is 3-5 days, after which bone traction can be started. The method is: move the traction fixing screw in the threaded dead rod of the guide rail by 0.2-0.25 mm daily according to the operator's design; the moving direction is determined according to the preoperative design. The moving distance depends on the preoperative design.
步骤六：牵引固定Step 6: Traction and fixation
在皮肤外进行。眶缘的移动依据术前设计，当牵引后的内外眶缘到达理想位置后（单侧或双侧），停止牵引。上述牵引装置通常需要在最后的位置安放1～6个月（依据术者而定）。Taken outside the skin. The movement of the orbital rim is based on the preoperative design. When the inner and outer orbital rims after traction reach the ideal position (unilateral or bilateral), the traction is stopped. The above-mentioned traction device usually needs to be placed in the final position for 1 to 6 months (depending on the operator).
步骤七：取出牵引装置Step 7: Take out the traction device
牵引眼眶缘和固定眼眶缘结束后取出皮肤外的装置。牵引杆可以自皮肤外用旋转方式自皮肤下和眶缘骨板取出。After the orbital rim is retracted and the orbital rim is fixed, the extracutaneous device is removed. The traction rod can be removed from the subcutaneous and orbital rim plates in a rotational manner externally from the skin.
