[0016] 本发明的有益效果如下: [0016] Advantageous effects of the present invention are as follows:

[0017] 1、本发明可依照治疗需要进行多种形状截骨手术,方便手术操作,增加了器械的适用范围。 [0017] 1, the present invention may be carried out in accordance with a variety of shapes osteotomy treatment requires convenient surgical procedure, increases the scope of the instrument. 例如:当本发明用于斜形截骨手术时,可增大骨愈合面积,保证骨折端的稳定,加快骨愈合速度。 For example: When the present invention is used for oblique osteotomy, bone healing area can be increased, to ensure the stability of the fracture, bone healing accelerated speed. 本发明用于Z形裁骨手术时,可适合于km以下的骨缺损的手术,而不需要植骨或异体移骨的治疗。 The invention is used a Z-cut bone surgery, it may be adapted to km or less surgical bone defects, without the need for allogeneic bone or treating bone shift. 本发明用于楔形截骨进行畸形骨整型时,可按适合角度进行楔形截骨,便于调整骨愈合角度达到正常力线。 When the present invention is used for osteotomy bone deformity integer, it may be suitable angle wedge osteotomy, bone healing easy to adjust the angle to normal line of force. 本发明还可以进行弧形截骨,按治疗要求将术骨进行水平旋转,有利于畸形骨矫形治疗。 The present invention may also be curved osteotomy, bone surgery according to the treatment required to rotate horizontally, facilitate orthopedic treatment of bone deformity.

[0018] 2、采用本发明进行的截骨手术属于微创手术,手术时先将软组织切开一小口,放入定位截骨端套管,再用截骨钻头钻孔,将截骨端定位针插入孔中,截骨端定位针和截骨钻头在截骨端套管内部相互转换位置进行定位截骨。 [0018] 2, the present invention belongs to the osteotomy minimally invasive surgery, soft tissue surgery first cut a small hole, into the positioning sleeve osteotomy, the osteotomy and then drill the borehole, positioning the osteotomy the needle insertion hole, osteotomy osteotomy positioning pins and the drill end of the sleeve inside the osteotomy positioning position conversion osteotomy. 截骨手术中,截骨端套管可拨开钻孔周围的神经和血管、软组织和骨膜,从而避免了钻头与软组织接触,造成组织损伤。 Osteotomy, the osteotomy end of the sleeve can be peeled nerves and blood vessels, periosteum and the soft tissue surrounding the borehole, the drill bit so as to avoid contact with soft tissue, causing tissue damage. 截骨产生微创切口,有利于促进骨重建、愈合。 Generating a minimally invasive incision osteotomy, bone remodeling and promoting healing.

[0019] 3、本发明在手术时可防止骨意外粉碎,减少缺损。 [0019] 3, the present invention can prevent accidental crushing bone during surgery, reduced defects. 已往在术骨的边缘处钻孔时,因钻头靠近外侧,极易造成侧骨粉碎、缺损。 In conventional drilling of bone at the edge of the surgery, due to the drill closer to the outside, easily cause side pulverized bone, defect. 本发明的在截骨端套管的下侧带有挡板,手术时挡板可贴紧术骨,起到护板的作用,防止骨侧面钻孔时引起的骨裂、粉碎和缺损。 Osteotomy lower side end of the sleeve of the present invention is provided with baffles which may be in close contact when the bone surgical procedures, functions as a shield to prevent bone fractures due to drilling side, pulverization and defects.

[0020] 4、截骨精确,定位调整导轨上带有刻度标尺,可精准定位术骨曲线、弧形等截骨线。 [0020] 4, osteotomy precise positioning ruler with a scale on the guide rail adjustment, precise positioning operation can be bone curves, arcs, etc. osteotomy. 参照术前X-ray片,可精准的将术骨按术前设计比例(角度)截下。 Referring preoperative X-ray film, can be precise bone surgery designed according to the preoperative ratio (angle) of the cut. 截骨钻头上的刻度标尺也便于确定术骨钻孔深度,防止造成下面骨侧软组织和神经的损伤,手术的准确率高达99%以上,截骨手术的安全性和准确性方面取得了实质性的突破。 Scale ruler on the osteotomy surgical bone drill is also easy to determine the drilling depth, prevent damage to the soft tissue and bone side below nerves, surgical accuracy as high as 99%, in safety and accuracy of the osteotomy surgery has made substantial breakthrough.

[0021] 5、本发明在弧形截骨时,能以定位针为圆心,自由转动调整定位导轨角度和纵向尺寸,方便医务人员操作,缩短手术时间,手术效果有保障。 [0021] 5, when the present invention is curved osteotomy, capable of positioning pins of a circle, rotatably adjusting the angle of the positioning guide and longitudinal dimensions, to facilitate medical personnel operate, to shorten the operation time, the effect is guaranteed.

[0022] 6、本发明具备多种功能,在进行斜形、Z形、楔形截骨手术时,截骨端套管可以单独使用。 [0022] 6, the present invention includes a variety of functions, performing oblique shaped, Z-shaped, the wedge osteotomy, the osteotomy end of the sleeve may be used alone. 在对术骨的边缘处钻孔时,也可以置换为带有挡板的截骨套管。 When the edge of the bone at the surgical drill, the sleeve may be replaced with a baffle osteotomy.

[0023] 本发明可广泛应用于干骨、畸型矫正的截骨手术,还可用于颅脑外科、颂面外科等的截骨手术。 [0023] The present invention can be widely used bone dry malformation correction osteotomy, may also be used for brain surgery, surgery, Chung surface of osteotomy.
