Description

骶髂关节骨折脱位复位器 Sacroiliac joint fracture dislocation is

本实用新型涉及一种骶髂关节骨折脱位复位器。 The present invention relates to a sacroiliac joint fracture dislocation device.

对于严重的不稳定性骨盆骨折,如早期处理不当,常可导致晚期因骨盆的不稳定而并发双下肢的不等长,骶髂关节痛和下腰部退行性病变。 For severe unstable pelvic fracture, such as improper early treatment can often lead late due to the instability of the pelvis and lower limbs of unequal length concurrent, sacroiliac joint pain and lower back degenerative diseases. 因而近年来在不稳定性骨盆骨折的治疗原则上有了新的观点,主张早期切开复位内固定。 Principle which in recent years in the treatment of unstable pelvic fracture a new perspective, cut advocate early internal fixation. 因而在治疗骶髂关节骨折进行内固定时,必须先进行复位,才能进行内固定。 Thus in the treatment of sacroiliac joint fracture internal fixation must be reset to be fixed. 如不能较好地复位,则无法进行内固定。 The reset is not better, it can not be fixed. 目前国内外尚无此复位器的研制。 This reset is currently no development at home and abroad. 传统的复位方法是在切开复位前进行单侧下肢或双侧下肢骨牵引或外固定架复位。 The conventional reset method resets unilateral or bilateral lower extremities or the lower extremities traction open reduction prior external fixator. 而目前国内外所研制的外固定架对其骶髂关节向上的脱位则不能复位,因而只能采用长时间骨牵引复位,这种复位的方法缺点是:第一,延长了切开复位内固定的时间,牵引复位往往达不到满意的对位,增加了手术难度和出血量,延长了病人住院时间,增加病人经济负担;第二,长时间牵引,易出现长期卧床而引起的肺部、泌尿系感染、结石形成和静脉血栓形成、脱落,严重者可出现生命危险。 At present, domestic and external fixation developed its dislocation direction is the sacroiliac joint can not be reset, which can only use a long bone traction, reset disadvantage of this method is: first, to extend within the internal fixation time, often less than satisfactory traction on the bit, increase the difficulty of operation and the amount of bleeding, prolong the patient's hospital stay, increasing the financial burden of patients; second, long traction, prone to lung caused by prolonged bed rest, urinary tract infections, stone formation and venous thrombosis, loss, severe cases can be life-threatening.

本发明的目的是为了提供一种可便于骶髂关节骨折早期手术、不需术前长时间肢体骨牵引和外固定架复位、复位方法简单、复位后可作暂时性固定的骶髂关节骨折脱位复位器。 Object of the present invention is to provide a facilitating early operation of the sacroiliac joint fracture, long before the body without surgery and external fixation of bone distraction reset which method is simple, can be reset temporarily fixed sacroiliac joint fracture and dislocation restorer.

本发明的目的可通过如下措施来实施:一种骶髂关节骨折脱位复位器,含有活动臂等;两活动臂呈剪刀状联接,在每一活动臂上设有一对复位爪,两对复位爪相向均向内弯成斜S形,其顶端向内弯与爪体成80°-90°夹角,两活动臂上的复位爪的下端相互成130°-150°的夹角;另在活动臂的绞接处连有锯齿形定位块,在定位块设有调节螺钉:每一活动臂上的两复位爪之间相互成30°-55°夹角。 The object of the present invention can be implemented by the following measures: one kind sacroiliac joint fracture dislocation, a movable arm comprising the like; two movable arms are coupled like scissors, a pair of pawls in each active reset arm, two claws reset obliquely bent inwards toward S-shaped, and the claw tip end thereof bent inwardly to -90 ° angle 80 °, the lower end of the mobile arm resets the pawl of two mutually an angle of 130 ° -150 °; other activities splices arm connected serrated positioning block, an adjusting screw positioning block: each other to form an angle 30 ° -55 ° between the two jaws of each active reset arm.

本发明相比现有技术具有如下优点:1、本实用新型根据骶髂关节的形状结构及生物力学的原理而设计为活动臂成剪状绞接,在每一活动臂上设有两个顶端向内弯成90°的复位爪;可便于复位爪刺入髂骨耳状关节,使复位方便、简单;另在活动臂的绞接处设有锯齿形定位块,并在其内设有调节螺钉,可便于调节复位爪之间的开口角,以便于适应不同型号的要求及夹持、扭曲力的要求,其夹持力可达40-50kg,旋转扭曲力可达50-70Kg;且将调节螺钉拧紧可定位,便于复位后作暂时性的稳定固定。 Compared with the prior art the present invention has the following advantages: 1, according to principles of the present invention, the shape of the structure and biomechanics of the sacroiliac joint is designed as a scissor arm is hinged, with two events in each top arm 90 ° inwardly bent pawl resetting; a return prong may facilitate piercing ears iliac joint, the reset convenient and simple; the other is provided with a zigzag positioning block splices moveable arm, and an adjustment features thereof screws, may facilitate adjusting the opening angle between the jaws reset to requirements and require clamping, twisting force to adapt to different models, the clamping force of up to 40-50kg, rotational twisting force of up to 50-70 kg; and the tighten the set screw may be positioned to facilitate the reset made after temporary stably fixed.

2、本实用新型可便于骶髂关节早期手术,而不需术前长时间肢体骨牵引和外固定架复位,从而缩短了病人的住院时间,可最大限度地减轻患者的痛苦及经济负担。 2, the present invention may facilitate the early operation of the sacroiliac joint, the long limb before surgery without external fixation and bone distraction reset, thereby shortening the patient's hospital stay, can minimize the pain and economic burden of patients.

3、本实用新型不需长时间牵引,因而消除了长时间卧床牵引所致的诸多严重合并症;且复位完全,术后功能恢复好。 3, the present invention does not need a long time traction, thus eliminating prolonged bed rest traction due to many serious complications; and reset completely, postoperative function recovery.
