本发明涉及骨科医疗器械领域，特别是一种便于定位的骨科钢板及定位方法。The invention relates to the field of orthopedic medical devices, in particular to an orthopedic steel plate and a positioning method for easy positioning.
背景技术Background technique
现有的骨科手术中，有需要用到骨科钢板，钢板形状多样，但是钢板螺孔形状比较固定，参见图4~6，在钢板上设有多个结合孔，如圆形、椭圆形、“8”字形等，用于在手术中穿入螺钉，以和骨骼固定连接。现有的手术步骤为：在皮肤上先开一小口，经过此小口置入长钢板，然后根据结合孔的位置，在皮肤上对应螺孔的位置开口，并用电钻在骨头上钻孔后穿入钢钉。当钢板置入皮下后，确定结合孔的位置是困难的。现有采用的方案是，在皮肤外利用辅助间接定位装置进行定位，由于钢板在皮下并不是平行的，且钢板本身很多也是复杂的三维曲面形状，采用测量样板定位的方案误差较大，而且此辅助间接定位装置使用多次后容易变形，导致定位不准，常需要增大创口，容易增加患者的痛苦。In the existing orthopedic surgery, it is necessary to use orthopedic steel plates. The shapes of the steel plates are various, but the shape of the screw holes of the steel plates is relatively fixed. See Figures 4-6. There are multiple bonding holes on the steel plates, such as circular, oval, " 8" shape, etc., used to penetrate screws during surgery to fix the connection with the bone. The existing surgical procedure is as follows: first open a small opening in the skin, insert a long steel plate through the small opening, and then according to the position of the joint hole, open an opening in the position corresponding to the screw hole on the skin, and use an electric drill to drill a hole in the bone and then penetrate into it. steel nails. When the plate is placed subcutaneously, it is difficult to determine the position of the binding hole. The existing solution is to use an auxiliary indirect positioning device for positioning outside the skin. Since the steel plates are not parallel under the skin, and many of the steel plates themselves are also complex three-dimensional curved surfaces, the positioning method using the measurement template has a large error, and this Auxiliary indirect positioning devices are easily deformed after being used many times, resulting in inaccurate positioning, often needing to enlarge the wound, and easily increasing the pain of the patient.

In the indicating and positioning device 3 , preferably, metal skeletons are provided on both sides of the longitudinal axis of the base belt 32 to provide support and maintain strength and elasticity. With this structure, it is convenient to accurately locate the position of the joint hole 2 by using the light emitted by the lamp bead 31 during the orthopedic operation, and facilitate subsequent operations of opening and installing steel nails. Lamp beads 31 are preferably low-energy lamp beads, such as LED lamps or OLED lamps
优选的方案中如图1~3中，基带32上与结合孔2相对应的位置设有凸台37，在凸台37内设有灯珠31，灯珠31与导线35连接，在凸台37的至少一侧设有倒钩部34，例如位于前侧，当放入骨科钢板时，倒钩部34用于勾住结合孔2的弯折部21，在取出时，拉动基带32后部即可使倒钩部34与弯折部21脱开，方便基带32的取出。优选的，在凸台37的两侧设有倒钩部34，倒钩部34用于勾住结合孔2的弯折部21。由此结构，便于指示定位装置3的安装和取下。通常结合孔2的结构，为具有一个弯折部21的“8”字形孔，倒钩部34正好卡在弯折部21的位置，从而使基带32与钢板1可靠连接，在送入皮下的过程中不会脱落。本例中的基带32优选采用医用硅胶，在凸台37的位置优选采用硬化处理。In the preferred solution, as shown in Figures 1 to 3, a boss 37 is provided on the base belt 32 at a position corresponding to the coupling hole 2, and a lamp bead 31 is arranged inside the boss 37, and the lamp bead 31 is connected to a wire 35, and the boss 37 is connected to the wire 35. At least one side of 37 is provided with a barb 34, for example, located on the front side. When the orthopedic steel plate is placed, the barb 34 is used to hook the bending part 21 of the joint hole 2. When taking it out, the rear part of the base belt 32 is pulled. That is, the barb portion 34 can be disengaged from the bending portion 21 to facilitate the removal of the base belt 32 . Preferably, barbs 34 are provided on both sides of the boss 37 , and the barbs 34 are used to hook the bent portion 21 of the coupling hole 2 . This structure facilitates the installation and removal of the indicating positioning device 3 . Usually, the structure of the combination hole 2 is an "8"-shaped hole with a bent part 21, and the barb part 34 is just stuck in the position of the bent part 21, so that the base belt 32 is reliably connected with the steel plate 1, and it is delivered subcutaneously. It will not fall off during the process. The base belt 32 in this example is preferably made of medical silicone, and the position of the boss 37 is preferably hardened.
可选的方案中，所述的凸台37位于基带32的上方，在凸台37的周围均设有倒钩部34。为了与骨骼更好贴合，在钢板1的底部横截面通常有内凹的弧形，基带32能够位于弧形内，在取出的过程中，可以利用钢钉，依次将凸台37从结合孔2内顶出，然后将整个基带32抽出。In an optional solution, the boss 37 is located above the base belt 32 , and barbs 34 are provided around the boss 37 . In order to better fit the bone, the bottom cross section of the steel plate 1 usually has a concave arc, and the base belt 32 can be located in the arc.

实施例2：Example 2:
在实施例1的基础上，一种采用上述的骨科钢板进行定位的方法，包括以下步骤：On the basis of embodiment 1, a kind of method adopting above-mentioned orthopedic steel plate to carry out positioning, comprises the following steps:
一、将钢板1从皮肤的开口置于预定位置；1. Place the steel plate 1 at the predetermined position from the opening of the skin;
二、开启指示定位装置3的灯珠31；2. Turn on the lamp bead 31 indicating the positioning device 3;
三、根据灯珠31发光光源的指示，在皮肤上与灯珠31相对应的位置做出标记，以定位结合孔2的位置；3. According to the indication of the light source of the lamp bead 31, mark the position corresponding to the lamp bead 31 on the skin to locate the position of the combining hole 2;
四、取出指示定位装置3；根据指示定位装置3安装位置的不同，分为从钢板1上方取出，和从钢板下方取出；4. Take out the indicating and positioning device 3; according to the different installation positions of the indicating and positioning device 3, it can be divided into taking out from the top of the steel plate 1 and taking out from the bottom of the steel plate;
如图3中所示，从上方取出时，可以将指示定位装置3取出后再进行在皮肤上开口、钻孔和装入钢钉的操作。该方案主要用于普通的钢板1中，例如图4中的直的钢板。As shown in FIG. 3 , when taken out from above, the operation of opening, drilling and loading steel nails can be performed after taking out the indicating and positioning device 3 . This solution is mainly used in common steel plates 1 , such as the straight steel plate in FIG. 4 .
从下方取出时，则需要先在皮肤上开口，以钢钉将凸台37从结合孔2顶出后，然后将指示定位装置3抽出，再进行钻孔和装入钢钉的操作。该方案主要用于形状较为复杂的钢板，例如图5、6中的钢板。图5、6中的钢板为较复杂的三维形状，在钢板插入过程中，需要确保指示定位装置3与钢板之间的连接可靠，不易脱落。When taking out from below, you need to open an opening on the skin earlier, after the boss 37 is pushed out from the combination hole 2 with steel nails, then the indicating positioning device 3 is extracted, and then the operations of drilling and packing into steel nails are carried out. This solution is mainly used for steel plates with relatively complex shapes, such as the steel plates in Figures 5 and 6. The steel plates in Figures 5 and 6 are relatively complex three-dimensional shapes. During the insertion of the steel plate, it is necessary to ensure that the connection between the indicating positioning device 3 and the steel plate is reliable and not easy to fall off.
通过以上步骤，实现结合孔2位置的准确定位。Through the above steps, accurate positioning of the position of the binding hole 2 is realized.
