1. A medical device, comprising:
an interspinous process device for maintaining a separation distance between two adjacent spinous processes in a spine of a human body, the interspinous process device comprising:
a main body having a cavity formed therein, the main body being configured to be disposed between the two adjacent spinous processes in the spine of the human body, and further comprising:
a base comprising a first spinous process contact portion, a fixing member, a side wall extending from the first spinous process contact portion, and a receiving slot formed on the side wall; and
a lid including a second spinous process contact portion and an interconnect member extending from the second spinous process contact portion towards the base, wherein:
the interconnect member is inserted in and moveably connected with the receiving slot in a spine direction of a longitudinal axis along the spine to form the main body and to adjust an engagement between the receiving slot and the interconnect member,
the engagement between the receiving slot and the interconnect member is adjusted for the main body to match the separation distance between the two adjacent spinous processes by adjusting a height of the cavity, and
the fixing member is arranged on the base along a lateral direction extending to left and right sides of the human body; and
a spacer configured to be arranged in the cavity of the main body and comprising a tool orienting slot for a tool to remove the spacer from the main body, wherein:
at least one of the lid and the base defines an orienting slot arranged thereon, the orienting slot extending parallel to a front-rear direction and perpendicular to the spine direction and the lateral direction to establish an orientation reference for the spacer,
the spacer is inserted in the cavity of the main body to fix the adjusted height of the cavity generated by the engagement between the receiving slot and the interconnect member, and
the spacer has a height selected from a plurality of appropriate lengths to be equal to the adjusted height of the cavity for the main body to match the separation distance between the two adjacent spinous processes, and
a stabilizing device for fixing the interspinous process device, the stabilizing device comprising:
a pair of wing structures, each wing structure configured to extend along the longitudinal axis of the spine, each of the pair of wing structures comprising:
a main body engaging portion located in a middle region of the wing structure, the main body engaging portion being configured to engage with the fixing member of the main body, wherein at least one of the pair of wing structures further comprises a fastener configured to be installed in a corresponding one of the main body engaging portions to fasten the main body and the stabilizing device together, and
an end portion configured to abut against one of the two adjacent spinous processes.
