Description

一种股骨截骨辅助器 A femoral osteotomy aid

技术领域 FIELD

[0001]本发明涉及医疗器械技术领域,尤其涉及一种为DDH (即developmental dysplasia of the hip,中文名称为“发育性髋关节脱位”)患儿实施股骨矫正手术的股骨截骨辅助器。 [0001] The present invention relates to the technical field of medical devices, and particularly to one for the DDH (i.e. developmental dysplasia of the hip, Chinese name "developmental dislocation of the hip") embodiment of the femur in children femoral osteotomy corrective surgery aid.

背景技术 Background technique

[0002]发育性髋关节脱位,其特点是股骨干4与髋臼8失去正常的对位关系,如图1所示, 大多数表现为股骨头部分或全部脱出髋臼,致使病变股骨相对正常股骨表现过长,而且病变常累及髋白、股骨头、关节囊和髋关节周围的軔带和肌肉。 [0002] developmental dislocation of the hip, femoral shaft 4 which is characterized by the loss of the normal acetabulum 8 para relationship, shown in Figure 1, most of the performance part or all of the femoral head acetabulum prolapse, resulting in lesions relative to normal femur the femur performance is too long, and white lesions often involving the hip, femoral head and hip joint capsule around the joint and muscle with firmware. 发育性髋关节脱位是常见的儿童骨骼发育性疾病,常常合并股骨前倾角增大,同时股骨前倾角增大也是导致继发髋臼发育不良的原因之一。 Developmental dislocation of the hip bone development of children is a common disease, often combined femoral anteversion increases, while increasing the angle of the front of the femur is one of the causes of secondary acetabular dysplasia. 一般来说,正常的股骨颈前倾角(即股骨颈轴线与股骨干冠状面所成的夹角)的大小在10〜30°之间,而脱位后的股骨颈前倾角通常在40〜60°之间,所以人体通常的拟矫前倾角的度数为10〜35 °。 In general, before the normal angle of the femoral neck (i.e., the axis of the femoral neck formed by the coronal plane angle) between the size of 10~30 °, the angle dislocation of the femoral neck is typically at 40~60 ° between, the front body usually pseudo correction angle in degrees 10~35 °.

[0003] 而发育性髋关节脱位的治疗原则为根据患儿的不同年龄和髋关节发育病理特点进行个性化的选择。 [0003] The principle of treating developmental dislocation of the hip is selected depending on the age of the individual children and pathological features of the hip joint development. 对大部分低龄患儿来说,闭合复位和石膏固定是非常有效的措施,但年龄较大的患儿往往需要手术治疗,例如对于年龄大于18个月的患儿,通常需要采用克氏针法进行治疗,通过切开复位加股骨旋转短缩截骨的方式来缩短病变过长的股骨和矫正角度过大的前倾角以作为治疗该病的主要手术治疗方法,该方法具体过程如下: For most young children, the closed reduction and cast immobilization is very effective measure, but older children often require surgery, for example for children older than 18 months, usually employed method Kirschner treatment, to shorten the long femoral lesion and the correct angle of anteversion too large by reduction with rotation of the femoral shortening osteotomy manner as the primary treatment for surgical treatment of the disease, which procedure is as follows:

[0004] 第1步,如图2所示,先确定拟矫正前倾角的具体度数,并且在股骨干4上找出位于股骨干远端41与股骨干近端42之间的股骨干截骨位43,所述的股骨千截骨位43具体是指在股骨干软骨面上缘至髋臼顶之间的距离,通常为1〜2cm。 [0004] Step 1, 2, to determine the specific degree prior to the intended correction angle, and find femoral osteotomy 42 located between the distal femoral and proximal femoral shaft 41 in the femur 4 43 bits, one thousand of the femoral osteotomy site 43 specifically refers to the edge surface of the femoral cartilage distance between the top of the acetabulum, typically 1~2cm. 然后在股骨干近端42的大转子上, 以垂直于股骨干近端42侧表面的方式插入一根作为导针7的克氏针,并且在目测拟矫正倾角度数后,以垂直于股骨干远端41侧表面的方式插入另一根作为导针7的克氏针,此时两根克氏针之间的夹角即为拟矫正前倾角的度数。 Then on the greater trochanter of the proximal femoral shaft 42, perpendicular to the embodiment is inserted proximal femoral shaft 42 as a side surface of the Kirschner guide pin 7, and the degree of the visual angle after correction intended to be perpendicular to the femoral shaft embodiment of the distal end surface 41 side as the insertion guide pin 7 of the other Kirschner, before this time is the angle between the two K-wires attempted correction angle degrees.

[0005] 第2步,如图3所示,采用截骨器裁掉股骨干截骨位43上的股骨以达到短缩病变过长的股骨;然后沿顺时针方向旋转股骨干远端41,直到股骨干远端41上的克氏针平行于股骨千近端42上的克氏针为止,从而达到矫正股骨颈前倾角度数的目的。 [0005] Step 2, 3 using an osteotomy cut on the femur 43 femoral femoral shortening osteotomy site in order to achieve long lesions; distal femoral shaft 41 is then rotated in the clockwise direction, Kirschner wire until the distal end of the femoral shaft 41 parallel to the Kirschner wire 42 until the proximal femur one thousand, so as to achieve the purpose of correcting the number of anteversion angle of the femoral neck.

[0006] 第3步,如图4所示,采用钢板5和螺钉6重新实现股骨干近端42与股骨干远端41间的衔接,拔除两根克氏针即可完成手术。 [0006] Step 3., using screw adapter plate 5 and 4 6 to re-implement the proximal femoral shaft 42 distal femoral shaft in FIG. 41, to complete the removal of two Kirschner surgery.

[0007] 然而,截骨长度及旋骨角度的准确性往往是直接影响能否获得良好预后的关键因素。 [0007] However, osteotomy bone length and accuracy of the angle of rotation is often the key factors that directly affect the availability of good prognosis. 而传统克氏针手术治疗过程中,由于手术医生只能通过目测法去确定股骨远端的旋转角度(即拟矫正前倾角的度数),然后在股骨上插刺所述两根克氏针,不但对手术医生的经验要求十分高,而且极易产生偏差,旋转角度不足和过大的发生率分别高达15%和44%,导致难以根治病根或者引发股骨干后脱位。 And Kirschner conventional surgical treatment, since only the surgeon to determine the rotation angle of the distal end of the femur (i.e., before the intended correction angle degrees) by visual observation, and the two stab Kirschner wire inserted in the femur, Not only the experience of the surgeon's requirements very high, and easy to produce bias, inadequate and excessive rotation angle of incidence as high as 15% and 44%, respectively, making it difficult to cure the root cause or lead to dislocation of the femoral shaft. 同时,在截骨的时候由于没有借助限位部件来准确控制截骨长度,容易导致截骨过短或过长现象,大大地影响了患者的健康。 Meanwhile, in the absence of the osteotomy time to accurately control the length of the osteotomy by means of a stopper member, easily lead osteotomy is too short or too long phenomenon, greatly affect the patient's health.
