外科手术，如矫形手术，往往需要利用手术工具对人体的骨头进行切割修整。现阶段医生和医疗技术员会根据切割修整的部位制作特别配合的支架，然后通过螺钉，定位针等将支架与待进行手术的部位进行固定，通过支架限定手术工具的操作方向及操作程度等等。因此支架的尺寸及支架的固定位置及角度等要求非常精确，以避免手术工具在操作是伤及神经线或韧带等等。Surgery, such as orthopedic surgery, often requires the use of surgical tools to cut and trim the bones of the human body. At the current stage, doctors and medical technicians will make specially matched stents according to the cut and trimmed parts, and then fix the stents to the part to be operated with screws, positioning pins, etc., and use the stents to limit the direction and degree of operation of the surgical tools. Therefore, the size of the stent and the fixed position and angle of the stent are required to be very accurate, so as to avoid injury to the nerve line or ligament during the operation of the surgical tool.
目前，医生所采用的支架一般都是使用塑料制作而成，主要考虑塑料成型相对方便。但是使用塑料支架也存在较多的问题，一方面固定支架时，医生只能通过目测观察塑料支架的摆放位置是否适当，其过程费时以致影响手术的进度。另一方面塑料的机械强度较差，受力后容易产生变形，尤其是采用手术锯刀进行操作时，锯刀与塑料支架摩擦产生高温，塑料在高温下会熔融和变形，由此在手术是就难以确保手术设计的效果并影响手术的精确度，甚至影响手术的成功率且需时较长，从而加重了医生及患者的身心负荷。At present, the stents used by doctors are generally made of plastic, mainly considering the relative convenience of plastic molding. However, there are also many problems with the use of plastic stents. On the one hand, when the stent is fixed, the doctor can only visually observe whether the placement of the plastic stent is appropriate. The process is time-consuming and affects the progress of the operation. On the other hand, the mechanical strength of plastic is poor, and it is easy to deform after being stressed. Especially when operating with a surgical saw, friction between the saw and the plastic bracket generates high temperature, and the plastic will melt and deform at high temperature. It is difficult to ensure the effect of the surgical design and affect the accuracy of the operation, and even affect the success rate of the operation and take a long time, thereby increasing the physical and mental load of the doctor and the patient.

实施例Examples
如图1至图3所示，手术用的刚性支架，至少设有与手术部分相贴合的贴合面1以及用于对手术工具进行操作定位的定位装置，所述刚性支架的贴合面1与手术部分贴合并固定，手术工具的操作部分限定在定位装置中。采用刚性的支架，由于其采用机械性能良好的物料制作而成，能够避免手术过程中操作手术工具导致刚性支架产生变形，保证了手术的精确度。而且刚性支架还设计了与手术部分相贴合的贴合面1，使得刚性支架的安装更加精确，进一步提高精确度。另外，整个刚性支架在X光下清楚可见,能让外科医生在手术期间能确认所述手术用金属支撑架的摆放位置，同样能够提高手术的精确度。As shown in FIG. 1 to FIG. 3, a rigid support for surgery is provided with at least a bonding surface 1 that is in conformity with a surgical part and a positioning device for operating and positioning a surgical tool. 1 It is attached and fixed to the surgical part, and the operating part of the surgical tool is limited to the positioning device. The use of a rigid stent, because it is made of materials with good mechanical properties, can prevent the rigid stent from being deformed due to the operation of surgical tools during the operation, and ensure the accuracy of the operation. In addition, the rigid support is also designed with a fitting surface 1 that fits the surgical part, which makes the installation of the rigid support more accurate and further improves the accuracy. In addition, the entire rigid support is clearly visible under X-rays, which allows the surgeon to confirm the placement position of the surgical metal support frame during the operation, and can also improve the accuracy of the operation.
骨科的外科手术，尤其是矫形手术，较为常见的是对骨头进行切削等操作，为此定位装置为锯刀槽2，其包括用于限定锯刀两侧的槽壁以及贯通整个刚性支架的锯刀槽2。手术操作时采用的手术工具一般是骨科锯刀，为了配合骨科锯刀的使用，一方面对骨科锯刀的操作方向进行控制，通过锯刀槽2两侧槽壁通过限定锯刀两侧，包括操作方向及操作范围等，以保证操作的精度；另一方面对骨科锯刀的操作程度进行控制，当锯刀的手柄与锯刀槽2的上表面接触时限制其操作的深度，以防止操作时伤及韧带或神经线等。Orthopaedic surgery, especially orthopedic surgery, is more common for cutting bones and other operations. For this purpose, the positioning device is a saw blade slot 2, which includes a slot wall for limiting the sides of the saw blade and a saw that penetrates the entire rigid support. Slot 2. The surgical tools used in surgical operations are generally orthopedic saws. In order to match the use of orthopedic saws, on the one hand, the operating direction of the orthopedic saw is controlled. The groove walls on both sides of the saw slot 2 pass through the sides of the saw blade, including Operating direction and operating range, etc., to ensure the accuracy of the operation; on the other hand, the degree of operation of the orthopedic saw is controlled, and the depth of operation is limited when the handle of the saw is in contact with the upper surface of the saw groove 2 to prevent operation Sometimes hurt ligaments or nerve lines.
医生在进行骨科手术前，首先需要将定位装置固定在相应的手术部位，一般采用螺钉或定位针等将定位装置锁定，为此刚性支架还设有用于将定位装置与手术部位固定的锁定槽3，有螺钉或定位针穿过锁定槽3并与手术部位连接固定。固定时锁定槽3同样可以限制螺钉过定位针插入的深度，防止操作时伤及韧带或神经线等。锁定槽3可根据使用的需要，设置于锯刀槽2的同一个槽壁的外侧或者分别设置于锯刀槽2的两侧。Before performing orthopedic surgery, the doctor first needs to fix the positioning device at the corresponding surgical site. Generally, the positioning device is locked by screws or positioning pins. For this purpose, the rigid bracket also has a locking groove for fixing the positioning device to the surgical site. There are screws or positioning pins that pass through the locking groove 3 and are connected and fixed with the surgical site. The locking groove 3 can also limit the depth of insertion of the screw through the positioning pin during fixing, and prevent injury to the ligaments or nerve wires during operation. The locking grooves 3 can be provided on the outside of the same groove wall of the saw blade groove 2 or respectively on both sides of the saw blade groove 2 according to the needs of use.
由于人体各个部位的骨骼结构不同且部分骨骼表面并不平整，如果只设置贴合面1难以将刚性支架精确定位到手术部位，为此还设置了辅助定位面，其与贴合面1相连并错开设置，辅助定位面也与手术部位贴合但是与贴合面1基本上在不同的平面，通过贴合面1及辅助定位面两者的配合，可以很好的将刚性支架与手术部位实现精确的定位并通过螺钉或定位针进行锁定，以人体手臂的桡骨靠近手腕位置为例，该处由于存在桡骨茎突，因此即便贴合面1能够与桡骨上表面相贴合，但是也难以精确定位，此时可以通过设置辅助定位面，该辅助定位面与桡骨侧面相贴合，这样就能能够将刚性支架对桡骨手术部位进行快速且精确的定位并进行固定。Because the skeletal structure of each part of the human body is different and part of the bone surface is not flat, it is difficult to accurately position the rigid bracket to the surgical site if only the fitting surface 1 is provided. For this purpose, an auxiliary positioning surface is also provided, which is connected to the fitting surface 1 and Staggered settings, the auxiliary positioning surface also fits with the surgical site but is basically on a different plane from the bonding surface 1. Through the cooperation of the fitting surface 1 and the auxiliary positioning surface, the rigid bracket and the surgical site can be well realized. Precise positioning and locking by screws or positioning pins. Taking the position of the radius of the human arm close to the wrist as an example, there is a radial styloid process, so even if the fitting surface 1 can fit the upper surface of the radius, it is difficult to be accurate. For positioning, at this time, an auxiliary positioning surface can be provided, and the auxiliary positioning surface is in contact with the side of the radius, so that the rigid stent can quickly and accurately locate and fix the radius surgery site.
为保证整体的强度，刚性支架采用金属或陶瓷制作而成，使其有足够强度作为切割手术的夹具且不易变形，另外即使在手术时切割产生高温的情况下也不变形。而且上述材料的密度较高，手术时刚性支架在X光下也能够清晰的显示出来，便于医生进行观察和判断。其制作可以采用3D打印方式制作，手术前先通过X光或核磁共振扫描的方式确定手术部位并获取手术部位的骨骼轮廓参数，依据这些参数建立刚性支架的3D模型，再通过3D打印机直接完成刚性支架的制造，这样可以保证贴合面1及辅助定位面能够与手术部位的骨骼充分贴合，保证了手术的精确度。In order to ensure the overall strength, the rigid support is made of metal or ceramic, which has sufficient strength as a fixture for cutting operation and is not easy to deform, and it is not deformed even when the cutting produces high temperature during the operation. In addition, the density of the above materials is high, and the rigid support can be clearly displayed under X-ray during surgery, which is convenient for doctors to observe and judge. The production can be made by 3D printing. Before surgery, the operation site is determined by X-ray or nuclear magnetic resonance scanning and the bone contour parameters of the operation site are obtained. Based on these parameters, a 3D model of the rigid scaffold is established, and then the rigidity is directly completed by a 3D printer. The manufacture of the stent can ensure that the fitting surface 1 and the auxiliary positioning surface can fully fit with the bones of the surgical site and ensure the accuracy of the surgery.
另外，刚性支架至贴合面1设有多处镂空，甚至可以形成网格形状，以便于医生能够通过镂空处观察刚性支架是否与手术部位的骨骼表面充分的贴合。In addition, the rigid support is provided with multiple cutouts to the fitting surface 1 and can even form a grid shape, so that the doctor can observe whether the rigid support fits the bone surface of the surgical site sufficiently through the cutout.
