一种组合式接骨板

Abstract

本实用新型公开了一种组合式接骨板，属于接骨板技术领域，包括：若干接骨块，所述接骨块一端对称设置有两个活动连接块，两个所述活动连接块与接骨块间装配有第一活动连接机构，所述接骨块上等间距开设有若干圆形骨钉孔，所述接骨块另一端设置有转动块，所述转动块与接骨块间装配有第一转动连接机构，所述转动块上设置有双头螺杆，所述双头螺杆与转动块间装配有第二转动连接机构，两个活动连接块与双头螺杆螺纹连接；本实用新型接骨块上设置转动结构，使组合式接骨板上的每个相邻接骨块间均能够根据待固定骨骼的弧度进行转动，以贴合受损骨骼的弧度，对受损骨骼弧度的位置不做要求，解决了现有技术存在的使用范围受限问题。

Claims

1. A combination bone plate, characterized in that include: A plurality of bone blocks (1), wherein two movable connecting blocks (2) are symmetrically arranged at one end of the bone block (1), and a first movable connecting mechanism is assembled between the two movable connecting blocks (2) and the bone block (1), and a plurality of circular bone screw holes (3) are equally spaced on the bone block (1), and a rotating block (5) is arranged at the other end of the bone block (1), and a first rotating connecting mechanism is assembled between the rotating block (5) and the bone block (1), and a double-ended screw (4) is arranged on the rotating block (5), and a second rotating connecting mechanism is assembled between the double-ended screw (4) and the rotating block (5), and the two movable connecting blocks (2) are threadedly connected to the double-ended screw (4); The first rotating connection mechanism includes two fixed seats (102) symmetrically fixed on the end wall of the bone block (1), and a rotating shaft (101) is connected between the two fixed seats (102) through a bearing. The rotating block (5) is fixedly sleeved on the rotating shaft (101) with an opening.

2. The combination bone plate of claim 1, wherein: The first movable connection mechanism includes a movable groove (201) opened inside the end wall of the bone block (1), a connecting seat (202) fixedly connected in the middle of the movable groove (201), a movable rod (203) fixedly connected inside the connecting seat (202), the two ends of the movable rod (203) being fixedly connected to the inner wall of the movable groove (201), and the movable connecting block (2) being movably sleeved on the movable rod (203) through an opening.

3. The combination bone plate of claim 2, wherein: The second rotating connection mechanism includes a through groove opened on the side wall of the rotating block (5) away from the rotating shaft (101). A double-headed screw (4) is set in the through groove and extends through the rotating block (5) to the outside of the rotating block (5) at both ends. The double-headed screw (4) is connected to the through section of the rotating block (5) through a bearing. The double-headed screw (4) is shorter than the movable rod (203) and the difference between the two is greater than the length of the movable connection block (2). The double-headed screw (4) is fixedly sleeved with a rotating handle (301) in the through groove.

4. The combination bone plate of claim 1, wherein: Two clamping blocks (7) are symmetrically arranged near the bone setting side of the bone block (1), and a second movable connecting mechanism is assembled between the two clamping blocks (7) and the bone block (1).

5. The combination bone plate of claim 4, wherein: The second movable connection mechanism includes a movable opening (402) inside the bone block (1) and a movable frame (401) fixed to the clamping block (7) near the side wall of the bone block (1). The movable opening (402) communicates with the corresponding circular bone screw hole (3). The two movable frames (401) extend into the movable opening (402) and are arranged in an upper and lower stacked structure. The movable frame (401) is provided with a waist-shaped bone screw hole (403) inside the movable opening (402). The two waist-shaped bone screw holes (403) overlap and communicate with the corresponding circular bone screw hole (3).

6. The combination bone plate of claim 1, wherein: The bone-setting block (1) and the clamping block (7) near the bone-setting side are respectively provided with arc-shaped grooves (6).
