本发明涉及医疗器械技术领域，具体涉及一种寰枢侧块关节撑开复位装置。The invention relates to the technical field of medical devices, in particular to an atlantoaxial mass joint retraction device.
背景技术Background technique
对于颅底凹陷，由于齿突上移陷入颅腔，对延脊髓造成压迫，导致四肢无力甚至瘫痪。临床上常通过在寰枢椎侧块间进行松解后，利用不同高度的模具试模逐次撑开寰枢椎侧块关节使得齿突逐渐下移，以便置入相应高度的融合器或植骨块，再辅以后路枕颈固定或前路寰枢固定纠正颅底凹陷。For skull basilar depression, the odontoid process moves up and sinks into the cranial cavity, causing compression on the spinal cord, resulting in weakness or even paralysis of the limbs. Clinically, after releasing the lateral mass of the atlantoaxial vertebrae, the atlantoaxial lateral mass joints are gradually stretched by using molds of different heights to gradually move the odontoid process down, so that fusion cages or bone grafts of corresponding heights can be placed. block, supplemented by posterior occipitocervical fixation or anterior atlantoaxial fixation to correct skull base depression.
对于寰枢椎脱位，多为寰椎向前下方脱位，寰枢椎之间不仅存在前后水平方向的脱位，也存在头尾垂直方向的脱位。此前对于头尾方向的脱位，当麻醉后颅骨牵引无法复位时，往往需要寰枢椎侧块关节间的松解，松解时需要利用不同高度的模具试模逐次撑开寰枢椎侧块关节使得垂直方向获得复位，以便置入相应高度的融合器或植骨块，再辅以后路或前路寰枢固定纠正前后方向的脱位以获得寰枢椎完全复位。For atlantoaxial dislocation, most of the atlantoaxial dislocations are forward and downward, and there are not only front-to-back horizontal dislocations, but also head-to-tail vertical dislocations between the atlantoaxial vertebrae. Previously, for dislocations in the craniocaudal direction, when the skull traction could not be reset after anesthesia, the atlantoaxial lateral mass joints often needed to be released. During the release, it was necessary to use different height molds to test the atlantoaxial lateral mass joints successively. The vertical direction is reduced so that fusion cages or bone grafts of the corresponding height can be placed, and the posterior or anterior atlantoaxial fixation can be used to correct the dislocation in the anteroposterior direction to obtain a complete reduction of the atlantoaxial spine.
上述在寰枢椎侧块间利用模具逐次松解撑开的方法，既有助于颅底凹陷的纠正也有利于寰枢椎脱位的复位，但是，由于模具的内侧为脊髓，外侧为椎动脉，上方为第二颈神经，这种反复多次插入和拔出模具的操作不仅操作繁复和撑开距离可控性差，导致手术效率低，而且增加了神经血管损伤的可能。The above-mentioned method of loosening and stretching the lateral masses of the atlantoaxial vertebrae by using the mold successively helps to correct the depression of the skull base and the reduction of the dislocation of the atlantoaxial vertebrae. However, since the inner side of the mold is the spinal cord and the outer side is the vertebral artery , above is the second cervical nerve. This operation of repeatedly inserting and pulling out the mold is not only complicated in operation and poor in controllability of the distraction distance, but also leads to low operation efficiency and increases the possibility of neurovascular injury.

推块4呈锥台形。The push block 4 is in the shape of a truncated cone.
使用时，旋转操作杆5，操作杆5的外螺纹与连接筒6的内螺纹配合实现操作杆5的移动，使推块4向开口方向推进，并行经两条连接条2之间，最后到达两块插入片3之间，两块插入片3被推块4撑开(撑开状态参见图6和图7)，由于推块4呈锥台形，推块4插入插入片3之间的部分越多，插入片3之间的间隙越大，若需要调节插入片3之间的间隙，可通过操作杆5推进或者推出推块4来调节。When in use, rotate the operating rod 5, and the external thread of the operating rod 5 cooperates with the internal thread of the connecting cylinder 6 to realize the movement of the operating rod 5, so that the push block 4 is pushed toward the opening direction, passes between the two connecting bars 2 in parallel, and finally reaches Between the two inserting pieces 3, the two inserting pieces 3 are stretched by the pushing block 4 (see Figure 6 and Figure 7 for the stretched state). Since the pushing block 4 is in the shape of a truncated cone, the pushing block 4 is inserted into the part between the inserting pieces 3 The more there are, the larger the gap between the insert pieces 3 will be. If the gap between the insert pieces 3 needs to be adjusted, it can be adjusted by pushing or pushing out the push block 4 through the operating rod 5 .
优选的，参见图3和图4，推块4的一端设有凹腔41，操作杆5靠近推块4的一端上设有与凹腔41相适配且用于卡入凹腔41的卡入端521，通过卡入端521与凹腔41的配合，将操作杆5与推块4活动连接。在旋转操作杆5时，由于操作杆5与推块4通过卡入端521与凹腔41活动连接，推块4会向开口11方向推进但不会随着操作杆5的旋转而旋转。Preferably, referring to FIG. 3 and FIG. 4 , one end of the push block 4 is provided with a concave cavity 41 , and the end of the operating rod 5 close to the push block 4 is provided with a card that is adapted to the concave cavity 41 and is used to snap into the concave cavity 41 The input end 521 movably connects the operating rod 5 and the push block 4 through the cooperation between the snap-in end 521 and the concave cavity 41 . When the operating rod 5 is rotated, since the operating rod 5 and the push block 4 are flexibly connected to the concave cavity 41 through the snap-in end 521 , the push block 4 will push toward the opening 11 but will not rotate with the rotation of the operating rod 5 .
进一步的，操作杆5包括螺杆51和连杆52，连杆52的一端与螺杆51的一端可拆卸连接，连杆52的另一端与推块4连接，螺杆51上具有外螺纹，螺杆51上的外螺纹与连接筒6的内螺纹配合实现整条操作杆5的移动，从而能够推动推块4向开口11方向行进；螺杆51和连杆52可拆卸连接，连杆52与推块4相连，当推块4的高度达不到复位高度要求时，可将连杆52连同推块4从螺杆51上拆下，更换不同高度的推块4。图5所示，实际使用时，寰枢侧块关节撑开复位装置应配套一组推块4和连杆52，一组推块4和连杆52内包括多个推块4和连杆52，连杆52的尺寸大小固定，与多个连杆52相连的多个推块4的高度有所不同，供不同的撑开复位高度使用。Further, the operating rod 5 includes a screw rod 51 and a connecting rod 52, one end of the connecting rod 52 is detachably connected to one end of the screw rod 51, and the other end of the connecting rod 52 is connected to the push block 4, the screw rod 51 has an external thread, and the screw rod 51 has an external thread. The external thread of the connecting cylinder 6 cooperates with the internal thread of the connecting cylinder 6 to realize the movement of the entire operation rod 5, thereby pushing the push block 4 to advance toward the opening 11; the screw rod 51 and the connecting rod 52 are detachably connected, and the connecting rod 52 is connected with the push block 4 , when the height of the push block 4 does not reach the reset height requirement, the connecting rod 52 can be removed from the screw rod 51 together with the push block 4, and the push block 4 of different heights can be replaced. As shown in Figure 5, in actual use, the atlantoaxial mass joint expansion reset device should be equipped with a set of push blocks 4 and connecting rods 52, and a set of push blocks 4 and connecting rods 52 includes multiple push blocks 4 and connecting rods 52 , the size of the connecting rod 52 is fixed, and the heights of the plurality of push blocks 4 connected with the plurality of connecting rods 52 are different, and are used for different retraction heights.
具体的，连杆52的一端与螺杆51的一端卡接，如图4所示，螺杆51的一端设有卡块511，连杆52的一端设有与卡块511相适配的卡槽522，通过块511和卡槽522实现连杆52与螺杆51的卡接，需要更换推块4时，可将连杆52拔出，更换更厚或者更薄的推块4。当然，连杆52的一端与螺杆51的一端也可以采用螺纹连接的方式，需要更换推块4时，可将连杆52旋出，相对于卡接，螺纹连接的方式更加稳固，但卡接连接的结构较易成型，制作工艺相对简单。Specifically, one end of the connecting rod 52 is engaged with one end of the screw rod 51. As shown in FIG. The connecting rod 52 and the screw rod 51 are connected through the block 511 and the locking groove 522. When the push block 4 needs to be replaced, the connecting rod 52 can be pulled out to replace the thicker or thinner push block 4. Of course, one end of the connecting rod 52 and one end of the screw rod 51 can also be threadedly connected. When the push block 4 needs to be replaced, the connecting rod 52 can be unscrewed. Compared with the clamping connection, the threaded connection is more stable, but the clamping The connected structure is easier to form, and the manufacturing process is relatively simple.
优选的，图8所示，推块4表面设置有凸条42，连接条2和插入片3表面均设有与凸条42相适配的导向槽9，凸条42滑动连接在导向槽9上，推块4通过凸条42能够沿着连接条2和插入片3表面的导向槽9行进，防止推块4行进时产生偏移，进而影响神经血管。Preferably, as shown in FIG. 8 , the surface of the push block 4 is provided with a convex strip 42 , and the surfaces of the connecting strip 2 and the insert piece 3 are provided with a guide groove 9 matching the convex strip 42 , and the convex strip 42 is slidably connected to the guide groove 9 Above, the push block 4 can travel along the guide groove 9 on the surface of the connecting bar 2 and the insertion piece 3 through the convex strip 42, so as to prevent the push block 4 from shifting when it travels, thereby affecting the nerve and blood vessels.
优选的，容纳框1的开口端呈锥形，方便推块4的推进。Preferably, the opening end of the receiving frame 1 is tapered to facilitate the pushing of the push block 4 .
优选的，操作杆5的另一端设置有把手7，旋转操作杆5时，可通过旋转把手7带动操作杆5旋转，操作更方便。Preferably, the other end of the operating rod 5 is provided with a handle 7. When the operating rod 5 is rotated, the rotating handle 7 can drive the operating rod 5 to rotate, which is more convenient to operate.
