Description

Translated fromChinese
一种脊柱脱位复位装置A spinal dislocation reduction device

技术领域Technical Field

本发明属于医疗设备技术领域,具体涉及一种脊柱脱位复位装置。The invention belongs to the technical field of medical equipment, and in particular relates to a spinal dislocation reduction device.

背景技术Background technique

脊柱骨折(脱位)作为常见创伤性疾病,以胸腰椎骨折最为常见,除了少数稳定性好的轻微骨折外,大多数都需要进行手术治疗,达到脊髓神经减压、恢复脊柱正常序列以及稳定脊柱的目的,以促进患者康复及提高生活质量。Spinal fracture (dislocation) is a common traumatic disease, with thoracic and lumbar fractures being the most common. Except for a few minor fractures with good stability, most of them require surgical treatment to decompress the spinal cord nerves, restore the normal sequence of the spine, and stabilize the spine, so as to promote patient recovery and improve the quality of life.

一般对于移位不明显或易复位的骨折,往往通过后路椎弓根螺钉联合钛棒手术方式便能够快速达到手术目的;但是,对于严重骨折脱位的脊柱骨折,目前常规治疗方式存在以下缺点:Generally, for fractures that are not obviously displaced or easily repositioned, the surgical purpose can be quickly achieved through posterior pedicle screw combined with titanium rod surgery; however, for spinal fractures with severe fractures and dislocations, the current conventional treatment methods have the following disadvantages:

1、骨折脱位严重,骨折端移位明显,有时甚至伴有骨折端卡压,常规器械复位不方便施力,无法施加较大牵引力来矫正脊柱,骨折端复位困难,难以达到功能复位;1. The fracture dislocation is serious, the fracture ends are obviously displaced, and sometimes even accompanied by compression of the fracture ends. Conventional instruments are not convenient for applying force to reduce the fracture ends, and it is impossible to apply a large traction force to correct the spine. It is difficult to reduce the fracture ends and achieve functional reduction;

2、脊柱骨折严重时,往往伴有脊髓神经压迫损伤,手术过程中应尽量保护脊髓神经,以免二次损伤,而术中常规器械在复位过程中无法控制复位力度,脊髓神经由于复位力量的变化较大,容易产生震荡损伤,加重脊髓损伤的风险;2. Severe spinal fractures are often accompanied by compression and injury of the spinal nerves. During surgery, the spinal nerves should be protected as much as possible to avoid secondary injury. Conventional instruments cannot control the reduction force during the reduction process. The spinal nerves are prone to concussion injury due to the large changes in reduction force, which increases the risk of spinal cord injury.

3、严重骨折脱位复位困难,延长了手术时间,可能造成患者失血增多,增加手术风险。因此,发明一种便于施加较大牵引力的脊柱骨折脱位复位装置,是本领域技术人员亟待解决的技术问题。3. Severe fracture dislocations are difficult to reduce, which prolongs the operation time, may cause increased blood loss in patients, and increase the risk of surgery. Therefore, inventing a spinal fracture dislocation reduction device that is convenient for applying a large traction force is a technical problem that needs to be solved urgently by those skilled in the art.

实施例1Example 1

如图1至图4所示:As shown in Figures 1 to 4:

一种脊柱脱位复位装置,其包括中枢锁扣1以及两组固定卡爪2,参见图1;其中,A spinal dislocation reduction device comprises a central locking buckle 1 and two sets of fixing claws 2, see FIG1 ; wherein:

中枢锁扣1上设置有固定杆11,固定杆11远离中枢锁扣1的一端设置有钛棒A111,中枢锁扣1的内部设置有驱动组件12,驱动组件12的操作端延伸至中枢锁扣1的外部;A fixing rod 11 is provided on the central locking buckle 1, and a titanium rod A111 is provided at one end of the fixing rod 11 away from the central locking buckle 1. A driving assembly 12 is provided inside the central locking buckle 1, and an operating end of the driving assembly 12 extends to the outside of the central locking buckle 1;

固定卡爪2为“L”字形结构,两组固定卡爪2分别位于中枢锁扣1的两个相对侧,固定卡爪2的短边的端部设置有钛棒B23,固定卡爪2的长边滑动设置在中枢锁扣1中并与驱动组件12传动连接,两组固定卡爪2与中枢锁扣1连接形成“m”字形结构;通过操作驱动组件12的操作端便能够控制两组固定卡爪2的短边同步的向远离或者靠近固定杆11的方向移动。The fixed claws 2 are of an "L"-shaped structure. The two groups of fixed claws 2 are respectively located on two opposite sides of the central lock buckle 1. A titanium rod B23 is provided at the end of the short side of the fixed claws 2. The long side of the fixed claws 2 is slidably arranged in the central lock buckle 1 and is transmission-connected to the driving assembly 12. The two groups of fixed claws 2 are connected to the central lock buckle 1 to form an "m"-shaped structure. By operating the operating end of the driving assembly 12, the short sides of the two groups of fixed claws 2 can be controlled to move synchronously in a direction away from or close to the fixed rod 11.

在对患者进行脊柱复位时,医护人员可以先在患者需要矫正的脊柱上放置椎弓根螺钉,然后将该脊柱脱位复位装置中的两组固定卡爪2上的钛棒B23分别与骨折(脱位)的两个脊柱上的椎弓根螺钉连接固定,并将固定杆11上的钛棒A111与两组固定卡爪2之间的椎体上的椎弓根螺钉连接固定;When performing spinal reduction on a patient, the medical staff can first place pedicle screws on the spine that needs to be corrected, and then connect and fix the titanium rods B23 on the two sets of fixing jaws 2 in the spinal dislocation reduction device to the pedicle screws on the two fractured (dislocated) spines respectively, and connect and fix the titanium rod A111 on the fixing rod 11 to the pedicle screws on the vertebral body between the two sets of fixing jaws 2;

然后,通过控制驱动组件12的操作端便可以驱动两组固定卡爪2的短边同步的向远离或者靠近固定杆11的方向移动,以便于轻松的牵引骨折的脊柱进行复位。Then, by controlling the operating end of the driving assembly 12, the short sides of the two groups of fixing claws 2 can be driven to move synchronously in a direction away from or close to the fixing rod 11, so as to easily pull the fractured spine for reduction.

驱动组件12的设置使得骨折的脊柱在复位时施力更加的轻松,从而使手术过程更加的简单轻松,并缩短手术时间。The arrangement of the drive assembly 12 makes it easier to apply force when resetting the fractured spine, thereby making the surgical procedure simpler and easier and shortening the surgical time.

本实施例中,上述的驱动组件12包括驱动齿轮121,参见图2;其中,In this embodiment, the driving assembly 12 includes a driving gear 121, see FIG. 2 ; wherein,

在对患者骨折的脊柱进行复位的过程中,医护人员可以通过工具(扳手、手钳等)转动驱动齿轮121,以更好的向骨折的脊柱施力,以轻松的牵引骨折的脊柱,完成脊柱的复位;During the process of resetting the fractured spine of the patient, the medical staff can use tools (wrench, pliers, etc.) to rotate the driving gear 121 to better apply force to the fractured spine, so as to easily pull the fractured spine and complete the resetting of the spine;

同时,驱动齿轮121与卡齿A224的配合能够精确的控制骨折脊柱的位移量,以避免出现因位移量过大而对患者的脊柱造成震荡损伤或者是加重脊髓损伤的情况,从而使手术过程更加的安全。At the same time, the cooperation between the driving gear 121 and the latch A224 can accurately control the displacement of the fractured spine to avoid concussion injury to the patient's spine or aggravation of spinal cord injury due to excessive displacement, thereby making the operation safer.

优选的,上述的驱动组件12还包括调节螺母122,参见图3;其中,Preferably, the driving assembly 12 further includes an adjusting nut 122, see FIG. 3 ; wherein,

驱动齿轮121的端面设置有转动部1211,转动部1211延伸至中枢锁扣1的外侧顶部,调节螺母122上设置有与转动部1211匹配的卡槽1221,调节螺母122通过卡槽1221与转动部1211的配合套设在驱动齿轮121上;The end surface of the driving gear 121 is provided with a rotating portion 1211, and the rotating portion 1211 extends to the outer top of the central locking buckle 1. The adjusting nut 122 is provided with a slot 1221 matching the rotating portion 1211, and the adjusting nut 122 is sleeved on the driving gear 121 through the matching of the slot 1221 and the rotating portion 1211;

医护人员可以利用工具扳动调节螺母122来驱动上述的驱动齿轮121转动,以更好的向骨折的脊柱上施力,完成脊柱的复位。Medical personnel can use tools to turn the adjusting nut 122 to drive the driving gear 121 to rotate, so as to better apply force to the fractured spine and complete the reduction of the spine.

更优选的,上述的转动部1211的截面形状为正方形,卡槽1221的截面形状与转动部1211的截面形状相匹配,避免在转动驱动齿轮121的过程中,驱动齿轮121与调节螺母122产生相对位移的情况发生,以进一步提高该脊柱脱位复位装置在使用时的安全性;More preferably, the cross-sectional shape of the rotating portion 1211 is a square, and the cross-sectional shape of the slot 1221 matches the cross-sectional shape of the rotating portion 1211, so as to avoid the relative displacement between the driving gear 121 and the adjusting nut 122 during the rotation of the driving gear 121, so as to further improve the safety of the spinal dislocation reduction device during use;

上述的调节螺母122的外侧壁为正六边形,以更好的适配市面上现有的扳手等工具。The outer side wall of the adjusting nut 122 is a regular hexagon so as to better fit the existing tools such as wrenches on the market.

优化的,上述的固定卡爪2的长边背离驱动齿轮121的一面设置有卡齿B225,再次参见图2,中枢锁扣1对应卡齿B225的侧边设置有限位卡扣13;Optimally, a side of the long side of the fixed claw 2 facing away from the driving gear 121 is provided with a latch tooth B225. Referring again to FIG. 2 , a side of the central lock buckle 1 corresponding to the latch tooth B225 is provided with a limit latch 13;

在使用过程中,限位卡扣13能够限制所固定卡爪2的短边向靠近固定杆11的方向移动,避免医护人员放开调节螺母122时,两个固定卡爪2在骨折的脊柱拖拽下回到初始位置(骨折时的位置)处,导致患者出现二次伤害的情况发生。During use, the limit buckle 13 can limit the short side of the fixed claw 2 from moving towards the fixing rod 11, preventing the two fixing claws 2 from being dragged back to the initial position (the position at the time of fracture) by the fractured spine when the medical staff releases the adjusting nut 122, causing secondary injury to the patient.

当然,在医护人员需要将骨折的脊柱向中部拖拽时,可以按压限位卡扣13远离固定卡爪2的一端,使限位卡扣13与卡齿B225分离,此时,医护人员再转动驱动齿轮121,便可以轻松的将两组固定卡爪2向中部收拢,以实现将骨折的脊柱向中部拖拽的效果。Of course, when medical staff need to drag the fractured spine toward the middle, they can press the limit buckle 13 away from one end of the fixed claw 2 to separate the limit buckle 13 from the tooth B225. At this time, the medical staff can easily turn the driving gear 121 to bring the two sets of fixed claws 2 toward the middle to achieve the effect of dragging the fractured spine toward the middle.

优化的,上述的限位卡扣13的中部铰接在中枢锁扣1上,限位卡扣13的铰接处设置有限位弹簧,限位弹簧的两端分别抵设在限位卡扣13以及中枢锁扣1上,使得限位卡扣13的抵接端始终卡设在卡齿B225中;Optimally, the middle part of the above-mentioned limit buckle 13 is hinged on the central lock buckle 1, and a limit spring is arranged at the hinge of the limit buckle 13, and the two ends of the limit spring are respectively abutted on the limit buckle 13 and the central lock buckle 1, so that the abutting end of the limit buckle 13 is always clamped in the clamping tooth B225;

卡齿B225远离固定卡爪2的短边的一面为垂直面,固定卡爪2的长边的轴线垂直于垂直面;卡齿B225靠近固定卡爪2的短边的一面为斜面;The side of the tooth B225 away from the short side of the fixed claw 2 is a vertical surface, and the axis of the long side of the fixed claw 2 is perpendicular to the vertical surface; the side of the tooth B225 close to the short side of the fixed claw 2 is an inclined surface;

限位卡扣13的卡设端在限位弹簧的作用下始终抵设在卡齿B225的垂直面上;The clamping end of the limit buckle 13 is always against the vertical surface of the clamping tooth B225 under the action of the limit spring;

当医护人员利用驱动组件12增加两个固定卡爪2的短边的距离(将骨折的脊柱向远离固定杆11的方向牵拉)时,限位卡扣13的卡设端能够沿着卡齿B225的斜面滑动,直至限位卡扣13的卡设端移动至该卡齿B225的斜面与垂直面的交汇处,此时,医护人员再次转动驱动组件12,也即两组固定卡爪2的短边再次向远离固定杆11的方向移动,限位卡扣13的卡设端便会在限位弹簧的作用下移动至该卡齿的垂直面的位置处,也即相邻两个卡齿B225之间的位置处;When the medical staff uses the driving assembly 12 to increase the distance between the short sides of the two fixing claws 2 (to pull the fractured spine away from the fixing rod 11), the clamping end of the limiting buckle 13 can slide along the inclined surface of the clamping tooth B225 until the clamping end of the limiting buckle 13 moves to the intersection of the inclined surface of the clamping tooth B225 and the vertical surface. At this time, the medical staff rotates the driving assembly 12 again, that is, the short sides of the two groups of fixing claws 2 move away from the fixing rod 11 again, and the clamping end of the limiting buckle 13 will move to the position of the vertical surface of the clamping tooth under the action of the limiting spring, that is, the position between two adjacent clamping teeth B225.

若此时医护人员不再转动驱动组件12,限位卡扣13的卡设端便能够抵设该卡齿B225的垂直面,以避免两组固定卡爪2的短边向靠近固定杆11的方向移动,而导致两个固定卡爪2在骨折的脊柱拖拽下回到初始位置(骨折时的位置)处,使得患者出现二次伤害的情况发生。If the medical staff no longer rotates the drive assembly 12 at this time, the locking end of the limit buckle 13 will be able to abut against the vertical surface of the locking tooth B225 to prevent the short sides of the two sets of fixing claws 2 from moving toward the fixing rod 11, causing the two fixing claws 2 to return to the initial position (the position at the time of fracture) under the dragging of the fractured spine, causing secondary injury to the patient.

需要说明的是,上述的限位卡扣13与卡齿B225的配合仅仅是为了对固定卡爪2进行单向限位,以提高该脊柱脱位复位装置的安全性;It should be noted that the cooperation between the above-mentioned limit buckle 13 and the latch tooth B225 is only for unidirectional limit of the fixed claw 2 to improve the safety of the spinal dislocation reduction device;

上述的限位弹簧为扭簧。The above-mentioned limit spring is a torsion spring.

优化的,上述的固定卡爪2包括爪体21和滑动杆22,参见图1和图4;其中,Optimally, the above-mentioned fixed claw 2 includes a claw body 21 and a sliding rod 22, see Figures 1 and 4; wherein,

爪体21的长度小于滑动杆22的长度,爪体21的固定端与滑动杆22的固定端连接形成“L”字形结构,也即,上述的固定卡爪2的长边为滑动杆22,固定卡爪2的短边为爪体21。The length of the claw body 21 is smaller than that of the sliding rod 22 , and the fixed end of the claw body 21 is connected to the fixed end of the sliding rod 22 to form an "L"-shaped structure, that is, the long side of the above-mentioned fixed claw 2 is the sliding rod 22 , and the short side of the fixed claw 2 is the claw body 21 .

优化的,上述的滑动杆22的固定端设置有穿孔222和两组限位块A221;Optimally, the fixed end of the sliding rod 22 is provided with a through hole 222 and two sets of limit blocks A221;

爪体21为矩形块状结构;The claw body 21 is a rectangular block structure;

两组限位块A221位于滑动杆22的下端面,两个限位块A221沿滑动杆22的长度方向排列设置,且两组限位块A221的间隙与爪体21的宽度相匹配,穿孔222位于两组限位块A221之间,穿孔222背离限位块A221的一面转动设置有旋转螺母A223;Two groups of limit blocks A221 are located on the lower end surface of the sliding rod 22. The two limit blocks A221 are arranged along the length direction of the sliding rod 22, and the gap between the two groups of limit blocks A221 matches the width of the claw body 21. The through hole 222 is located between the two groups of limit blocks A221. A rotating nut A223 is rotatably arranged on one side of the through hole 222 away from the limit block A221.

上述的爪体21的固定端设置有螺杆A211,爪体21滑动设置在两组限位块A221之间,螺杆A211穿过穿孔222与旋转螺母A223螺纹连接;The fixed end of the above-mentioned claw body 21 is provided with a screw rod A211, and the claw body 21 is slidably arranged between the two sets of limit blocks A221, and the screw rod A211 passes through the through hole 222 and is threadedly connected with the rotating nut A223;

当患者的脊柱骨折伴有前后(前胸后背方向)错位时,医护人员可以利用驱动组件12驱动两组固定卡爪2动作,实现对骨折脊柱的牵引/拖拽,然后再通过拧动旋转螺母A223来调整爪体21与滑动杆22之间的距离,利用爪体21拉动或推动错位的脊柱,以实现对脊柱前后错位的矫正。When the patient's spinal fracture is accompanied by anterior-posterior (front chest and back back direction) dislocation, medical staff can use the driving component 12 to drive the two sets of fixed claws 2 to achieve traction/dragging of the fractured spine, and then adjust the distance between the claw body 21 and the sliding rod 22 by turning the rotating nut A223, and use the claw body 21 to pull or push the dislocated spine to achieve correction of the anterior-posterior dislocation of the spine.

当然,爪体21与滑动杆22之间的间距可调也是为了匹配患者的脊柱,因为,脊柱并非是笔直的柱状结构,其具有一定的弯曲弧度,患者的骨折处也不一定在同一平面的直线上;Of course, the adjustable distance between the claw body 21 and the sliding rod 22 is also to match the patient's spine, because the spine is not a straight columnar structure, it has a certain curvature, and the patient's fracture is not necessarily on the same plane;

所以,通过调整爪体21与滑动杆22之间的间距可以使该脊柱脱位复位装置更好的适配患者的脊柱,以完成脊柱复位工作。Therefore, by adjusting the distance between the claw body 21 and the sliding rod 22, the spinal dislocation reduction device can be better adapted to the patient's spine to complete the spinal reduction work.

需要说明的是,上述的限位块A221能够限制爪体21的动作方向(仅能向靠近/远离滑动杆22的方向移动),不会绕着螺杆A211的轴线转动,以使该脊柱脱位复位装置在使用时更加的安全、方便。It should be noted that the above-mentioned limit block A221 can limit the movement direction of the claw body 21 (can only move towards/away from the sliding rod 22) and will not rotate around the axis of the screw A211, so that the spinal dislocation reduction device is safer and more convenient when used.

优化的,上述的穿孔222为圆形通孔,穿孔222的内侧壁设置有限位槽2221,限位槽2221环绕穿孔222的圆周方向设置;Optimally, the above-mentioned through hole 222 is a circular through hole, and the inner side wall of the through hole 222 is provided with a limiting groove 2221, and the limiting groove 2221 is arranged around the circumferential direction of the through hole 222;

旋转螺母A223的外侧壁设置有与限位槽2221匹配的限位凸起2231,限位凸起2231环绕旋转螺母A223的旋转中心设置,旋转螺母A223通过限位凸起2231与限位槽2221的配合转动设置在穿孔222处,以避免旋转螺母A223沿螺杆A211的轴线方向移动,使得旋转螺母A223在转动时能够驱动爪体21向靠近/远离滑动杆22的方向移动,从而实现脊柱前后错位的矫正。The outer wall of the rotating nut A223 is provided with a limiting protrusion 2231 matching the limiting groove 2221. The limiting protrusion 2231 is arranged around the rotation center of the rotating nut A223. The rotating nut A223 is arranged at the through hole 222 through the coordinated rotation of the limiting protrusion 2231 and the limiting groove 2221 to prevent the rotating nut A223 from moving along the axial direction of the screw A211, so that the rotating nut A223 can drive the claw body 21 to move toward/away from the sliding rod 22 when rotating, thereby realizing the correction of the anterior-posterior misalignment of the spine.

实施例2Example 2

如图2、图5至图7所示:As shown in Figure 2, Figure 5 to Figure 7:

作为本发明的另一种实施方案,上述的中枢锁扣1的下端面设置有通孔14和两组限位块B15,参见图5至图7;As another embodiment of the present invention, the lower end surface of the central locking buckle 1 is provided with a through hole 14 and two sets of limit blocks B15, see FIGS. 5 to 7 ;

固定杆11为矩形块状结构;The fixing rod 11 is a rectangular block structure;

The through hole 14 is located between the two sets of limit blocks B15. The through hole 14 penetrates to the outer top of the central locking buckle 1. A rotating nut B16 is provided on the top of the central locking buckle 1.

固定杆11的固定端设置有螺杆B17,固定杆11滑动设置在两组限位块B15之间,螺杆B17穿过通孔14与旋转螺母B16螺纹连接;A screw rod B17 is provided at the fixed end of the fixed rod 11. The fixed rod 11 is slidably disposed between the two sets of limit blocks B15. The screw rod B17 passes through the through hole 14 and is threadedly connected to the rotating nut B16.

当患者的脊柱骨折伴有前后(前胸后背方向)错位时,医护人员可以拧动旋转螺母B16来调整固定杆11与中枢锁扣1之间的距离,利用固定杆11拉动或推动错位的脊柱,以实现对脊柱前后错位的矫正。When the patient's spinal fracture is accompanied by anterior-posterior (front chest and back back) dislocation, medical staff can turn the rotating nut B16 to adjust the distance between the fixing rod 11 and the central lock buckle 1, and use the fixing rod 11 to pull or push the dislocated spine to correct the anterior-posterior dislocation of the spine.

当然,固定杆11与中枢锁扣1之间的间距可调也是为了匹配患者的脊柱,因为,脊柱并非是笔直的柱状结构,其具有一定的弯曲弧度,患者的骨折处也不一定在同一平面的直线上;Of course, the adjustable distance between the fixing rod 11 and the central locking buckle 1 is also to match the patient's spine, because the spine is not a straight columnar structure, it has a certain curvature, and the patient's fracture is not necessarily on the same plane;

所以,通过固定杆11与中枢锁扣1之间的间距可以使该脊柱脱位复位装置更好的适配患者的脊柱,以完成脊柱复位工作。Therefore, the distance between the fixing rod 11 and the central locking buckle 1 can make the spinal dislocation reduction device better adapt to the patient's spine to complete the spinal reduction work.

需要说明的是,上述的限位块B15能够限制固定杆11的动作方向(仅能向靠近/远离中枢锁扣1的方向移动),不会绕着螺杆B17的轴线转动,以使该脊柱脱位复位装置在使用时更加的安全、方便。It should be noted that the above-mentioned limit block B15 can limit the movement direction of the fixing rod 11 (it can only move towards/away from the central locking buckle 1) and will not rotate around the axis of the screw B17, so that the spinal dislocation reduction device is safer and more convenient when used.

优化的,上述的通孔14为圆形通孔,在驱动组件12上设置有便于螺杆B17穿过的贯穿孔,参见图7,驱动组件12的顶部设置有截面形状为圆形的沉槽,沉槽的侧壁上设置有限位卡槽,限位卡槽环绕沉槽的圆周方向设置;Optimally, the through hole 14 is a circular through hole, and a through hole is provided on the driving assembly 12 for the screw B17 to pass through. Referring to FIG. 7 , a sink with a circular cross-section is provided on the top of the driving assembly 12, and a limit groove is provided on the side wall of the sink, and the limit groove is provided around the circumferential direction of the sink;

旋转螺母B16的外侧壁设置有与限位卡槽匹配的卡块,卡块环绕旋转螺母B16的旋转中心设置,旋转螺母B16通过卡块与限位卡槽(与实施例一中的限位凸起2231与限位槽2221结构相同)的配合转动设置在沉槽处,以避免旋转螺母B16沿螺杆B17的轴线方向移动,使得旋转螺母B16在转动时能够驱动固定杆11向靠近/远离中枢锁扣1的方向移动,从而实现脊柱前后错位的矫正。The outer wall of the rotating nut B16 is provided with a block matching the limiting slot, and the block is arranged around the rotation center of the rotating nut B16. The rotating nut B16 is arranged in the recessed groove through the coordinated rotation of the block and the limiting slot (the same structure as the limiting protrusion 2231 and the limiting slot 2221 in Example 1) to prevent the rotating nut B16 from moving along the axial direction of the screw rod B17, so that the rotating nut B16 can drive the fixing rod 11 to move in the direction close to/away from the central lock buckle 1 when rotating, thereby realizing the correction of the anterior-posterior misalignment of the spine.

需要说明的是,上述的旋转螺母B16与驱动组件12为活动配合,也即旋转驱动组件12时,旋转螺母B16不会随着驱动组件12一同动作;而在旋转旋转螺母B16时,驱动组件12不会随着驱动组件12一同动作,以使该脊柱脱位复位装置的使用更加的安全、方便。It should be noted that the above-mentioned rotating nut B16 and the driving component 12 are movably matched, that is, when the driving component 12 is rotated, the rotating nut B16 will not move together with the driving component 12; and when the rotating nut B16 is rotated, the driving component 12 will not move together with the driving component 12, so as to make the use of the spinal dislocation reduction device safer and more convenient.

本实施例中,固定卡爪2为固定结构,其爪体21与滑动杆22为固定连接,爪体21与滑动杆22之间的间距无法进行调节;此外,本实施例中的其他结构与实施例一中记载的脊柱脱位复位装置的结构完全相同,此处便不再重复赘述,具体可以参考实施例一中的内容。In this embodiment, the fixed claw 2 is a fixed structure, and its claw body 21 and the sliding rod 22 are fixedly connected, and the distance between the claw body 21 and the sliding rod 22 cannot be adjusted; in addition, the other structures in this embodiment are exactly the same as the structure of the spinal dislocation reduction device recorded in Example 1, and will not be repeated here. For details, please refer to the contents of Example 1.
