[0024] like Figure 1-Figure 4As shown, the technical solution adopted in this embodiment is as follows: a drilling auxiliary device for orthopedic surgery, comprising: a fixing frame 1, a binding assembly is fixedly arranged on the upper part of the fixing frame 1, a cardboard 5 is slidably arranged on the lower part of the fixing frame 1, multiple groups of slide grooves 9 are symmetrically arranged on both sides of the cardboard 5, a locking block 10 is slidably arranged in the slide groove 9, the end of the locking block 10 located outside the cardboard 5 is an inclined surface lowered to the outside, a first spring 11 is fixedly arranged on the end of the locking block 10 located in the slide groove 9, and the end of the first spring 11 away from the locking block 10 is fixedly connected to the inner wall of the slide groove 9. A circular hole is opened in the middle of the cardboard 5, a round rod 6 is movably arranged in the circular hole, and a handle 7 is fixedly arranged at the lower end of the round rod 6. Draw ropes 12 are symmetrically arranged on both sides of the round rod 6, and the end of the draw rope 12 away from the round rod 6 is fixedly connected to the corresponding locking block 10, and a rubber plate 8 is fixedly arranged on the upper part of the cardboard 5, and the rubber plate 8 is located below the binding assembly.

[0025] The device can be fixed on the bed by moving the card plate 5 to drive the rubber plate 8 to move up and down, so that the patient's limbs can be fixed through the binding assembly to facilitate drilling. Pushing the card plate 5 to move upward can make the locking block 10 contact with the fixing frame 1, and be pushed by the fixing frame 1 to move into the slide groove 9, so that the rubber plate 8 can move up quickly to quickly fix the drilling auxiliary device on the bed, increase the installation speed, and avoid adverse effects on the surgical process. When disassembly is required, it is only necessary to move the round rod 6, and the pull rope 12 can be driven by the round rod 6, so that the pull rope 12 pulls the locking block 10 to move into the slide groove 9, and the device can be quickly removed from the bed, which is more convenient to use.

[0026] The fixing frame 1 is L-shaped, the binding assembly is fixedly arranged at the upper part of the vertical section of the fixing frame 1, and the clamping plate 5 is slidably arranged at one end of the horizontal section of the fixing frame 1. The binding assembly includes a placement plate 2 and a strap 3. A fixing plate 4 is fixedly arranged at the upper part of the vertical section of the fixing frame 1, and the fixing plate 4 is located above the horizontal section of the fixing frame 1. The placement plate 2 is fixedly arranged at the upper part of the fixing plate 4, and a groove is provided in the middle part of the placement plate 2. Straps 3 are fixedly arranged on both sides of the placement plate 2. The device is clamped on the bed by the fixing plate 4 and the rubber plate 8, and the patient's limbs are placed in the grooves, and then the patient's limbs are fixed with the straps 3, and drilling can be performed.

[0027] The round rod 6 is slidably arranged in the round hole in the clamping plate 5, and a second spring 13 is fixedly arranged on the upper end of the round rod 6, and one end of the second spring 13 away from the round rod 6 is fixedly connected to the top of the round hole. The round rod 6 is pulled downward by the handle 7, and the second spring 13 is stretched. At the same time, the round rod 6 drives the pull rope 12, so that the pull rope 12 pulls the locking block 10 to slide into the slide groove 9, so that the locking block 10 is separated from the fixing frame 1, and the device can be quickly removed from the bed.

[0028] Working principle: When in use, first place the rubber plate 8 and the fixing plate 4 below and above the bed board respectively, then push the card plate 5 upward, the card plate 5 drives the locking block 10 to move upward, so that the inclined surface of the locking plate contacts the fixing frame 1, and is squeezed into the slide groove 9 by the fixing frame 1, so that the card plate 5 can move upward smoothly. When the rubber plate 8 contacts the lower part of the bed board, the card plate 5 is pushed upward again, so that the rubber plate 8 is squeezed and deformed. At this time, the locking block 10 passes over the horizontal section of the fixing frame 1 and moves outward under the action of the first spring 11, so that the locking plate extends above the fixing frame 1, preventing the card plate 5 from moving downward, so that the rubber plate 8 and the fixing plate 4 clamp the bed board, so that the device is quickly fixed to the bed, improving the installation speed, and avoiding the adverse effects on the drilling and surgical process due to slow installation.

[0029] Then, the patient's limb is placed in the groove on the placement plate 2 and fixed with a strap 3 to start drilling.

[0030] After the operation, the bandage 3 is loosened and the patient's limb is taken off the placement board 2. Then the handle 7 is pulled downward, and the handle 7 first drives the round rod 6 to move downward, so that the second spring 13 is stretched, and at the same time the round rod 6 drives the pull rope 12 to move downward, and the pull rope 12 drives the locking block 10 to move into the slide groove 9, thereby releasing the obstruction of the card plate 5, and the card plate 5 drives the rubber plate 8 to move downward to remove the device from the bed.

[0031] Embodiment 2

[0032] like Figure 5 As shown, the difference between this embodiment and the first embodiment lies in the connection method between the round rod 6 and the clamping plate 5, and the specific technical scheme adopted is as follows: the round rod 6 is rotatably set in the circular hole of the clamping plate 5, and a torsion spring 14 is movably sleeved on the outer peripheral surface of the upper end of the round rod 6, one end of the torsion spring 14 is fixedly connected to the round rod 6, and the other end of the torsion spring 14 is fixedly connected to the inner wall of the circular hole.

[0033] During the use of this embodiment, the installation steps are the same as those of the first embodiment. When it is necessary to dismantle, the handle 7 is rotated to make the gripper drive the round rod 6 to rotate, so that the round rod 6 is wound around the pull rope 12, and the locking block 10 is pulled into the slide groove 9 through the pull rope 12 to complete the dismantling of the device.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
