具体实施方式 detailed description
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.
本实施例的精准定位锥间孔微创通道装置如图 1 所示，包括：定位通道管 2 、扩张管 1 和磨钻 3
，定位通道管 2 可插拔地套在扩张管 1 内。如图 2 所示，定位通道管 2 包括：定位杆 21 及位于定位杆 21 一侧的导向管 22 ，导向管 22
的轴线与定位杆 21 的轴线平行，定位杆 21 的定位头部 211 沿长度方向（即定位杆 21 或导向管 22 的轴线方向）伸出导向管 22 。磨钻 3
可插拔地套在导向管 22 内。 The precise positioning inter-cone hole minimally invasive channel device of this embodiment is shown in FIG. 1 and includes: positioning channel tube 2, dilation tube 1 and grinding drill 3
The positioning channel tube 2 is insertably inserted into the expansion tube 1. As shown in FIG. 2, the positioning channel tube 2 includes: a positioning rod 21 and a guiding tube 22 on one side of the positioning rod 21, and the guiding tube 22
The axis is parallel to the axis of the positioning rod 21, and the positioning head 211 of the positioning rod 21 projects out of the guide tube 22 in the longitudinal direction (i.e., the axis of the positioning rod 21 or the guide tube 22). Grinding drill 3
It is inserted in the guide tube 22 in a pluggable manner.
磨骨手术时，先将扩张管 1 沿切口插入，再将定位通道管 2 插入扩张管 1 中，并使定位头部 211
顶在患处旁边，使得磨钻 3 穿过导向管 2 后正好对准需磨削的部位，以实现定位。在将磨钻穿过导向管进行磨骨的过程中，由于定位头部 211
受外力顶住不动，避免了磨钻 3 产生滑脱，可保持磨钻 3 一直精准地进行磨骨。而且定位头部 211
定位后能按医生想法以定位点为支点旋转来磨削干涉部位，使得磨削更加方便。 In the case of bone surgery, the dilatation tube 1 is inserted along the incision, and the positioning channel tube 2 is inserted into the dilation tube 1 and the positioning head 211 is placed.
The top is next to the affected area, so that the grinding drill 3 passes through the guiding tube 2 and is just aligned with the part to be ground to achieve positioning. In the process of grinding the drill through the guide tube, since the positioning head 211
The external force can withstand the movement, avoiding the grinding of the drill 3 and the slippage, and keeping the grinding drill 3 accurately grinding the bone. And positioning the head 211
After positioning, the interference can be ground by using the positioning point as a fulcrum according to the doctor's idea, which makes grinding more convenient.
本实施例中，定位杆 21 与导向管 22 一体成型，增加了整个定位通道管 2 的稳定性。 In this embodiment, the positioning rod 21 is integrally formed with the guide tube 22, which increases the stability of the entire positioning channel tube 2.
导向管 22 靠近定位头部 211 的一端开口呈倾斜设置，开口端面垂直于导向管 22 的轴线和定位杆 21
的轴线确定的平面，且开口边缘上离定位杆 21 越远的点在长度方向上离定位头部 211 越远，即形成图 2 中导向管 22 靠近定位头部 211
的一端的倾斜开口。该倾斜开口设计使得定位通道管 2
插入后更加地充分避开患处脊凸的干涉区（此部位需磨削掉以充分暴露患处），以保证后续磨骨工作精准顺利地进行。 The opening of the guide tube 22 near the positioning head 211 is inclined, and the opening end surface is perpendicular to the axis of the guide tube 22 and the positioning rod 21
The axis defined by the axis, and the further the point on the edge of the opening from the positioning rod 21 is further away from the positioning head 211 in the longitudinal direction, that is, the guide tube 22 in Fig. 2 is formed close to the positioning head 211.
An inclined opening at one end. The inclined opening design makes the positioning channel tube 2
After the insertion, the interference area of the ridge of the affected area is more fully avoided (this part needs to be ground to fully expose the affected part) to ensure the accurate and smooth operation of the subsequent bone grinding work.
由于本设计中的定位通道管 2
为双通道，径向尺寸有长端和短端，若还采用与长端尺寸匹配的直径扩张管（即圆管）将使创口面增大，加大术后感染风险。因此，本实施例中，扩张管 1
的截面为椭圆形，椭圆的长轴与长端尺寸匹配，短轴与短端尺寸匹配，从而减小创口面积，便于术后恢复。 Due to the positioning channel tube 2 in this design
For the dual channel, the radial dimension has a long end and a short end. If a diameter dilatation tube (ie, a round tube) matching the long end dimension is also used, the wound surface is enlarged to increase the risk of postoperative infection. Therefore, in this embodiment, the expansion tube 1
The cross section is elliptical, the long axis of the ellipse matches the long end dimension, and the short axis matches the short end dimension, thereby reducing the wound area and facilitating postoperative recovery.
在磨骨时，通常是医生手持磨钻的手持端（与定位头部 211
相对的另一端）旋转，本实施例中还包括：手柄，而且定位杆 21 的手持端还设有与手柄可拆卸连接的连接部 31
。手柄使得握持更方便，更省力，尤其适合磨骨量大的情况。对于磨骨量小的精细磨骨，可以不加手柄，这样手感及磨骨时反馈更好。 When grinding bones, it is usually the hand held end of the doctor holding the grinding drill (with the positioning head 211
The opposite end of the rotation, the embodiment further includes: a handle, and the hand-held end of the positioning rod 21 is further provided with a connecting portion detachably connected to the handle.
. The handle makes it easier to hold and saves effort, especially for large bones. For the fine grinding bone with small amount of bone grinding, the handle can be omitted, so that the feedback is better when the hand feels and the bone is worn.

In the middle dashed box, the side wall is further provided with a limit stop 47, and the boss and the limit stop 47 are respectively located at the two ends of the protrusion to block the pin from moving away from the end of the spring 46.
如图 4 所示，为未按下按钮 45 时的初始状态，第一开口和第二开口相互错开，形成不规则的孔，磨钻 3
的连接部 31 无法插入，限位挡块 47 与凸出部配合将插销限制在中空外壳 44 内。当需要装上手柄时，如图 5 所示，按压按钮 45 ，弹簧 46
压缩，中空外壳 44 底部的凸台起到限位作用，使第一开口和第二开口形成容纳连接部 31 插入的开口。插入连接部 31 后松开按钮 45 ，由于弹簧 46
回弹，插销卡住磨钻 3 的连接部 31 的环形凹槽 311 ，从而卡紧磨钻 3 。 As shown in Fig. 4, in the initial state when the button 45 is not pressed, the first opening and the second opening are staggered from each other to form an irregular hole, and the grinding drill 3
The connection portion 31 cannot be inserted, and the limit stop 47 cooperates with the projection to restrain the pin in the hollow housing 44. When the handle needs to be attached, as shown in Figure 5, press button 45, spring 46
Compressed, the boss at the bottom of the hollow outer casing 44 acts as a stop so that the first opening and the second opening form an opening into which the receiving portion 31 is inserted. Insert the connector 31 and release the button 45 due to the spring 46
After rebounding, the latch catches the annular groove 311 of the connecting portion 31 of the grinding drill 3, thereby clamping the grinding drill 3 .
