[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1-4, an embodiment provided by the present utility model: a pressure relief screw for medical orthopedics, including a fixing block 1, a pressure relief screw 2 and two fixing screws 3. The two fixing screws 3 are arranged at the top end of the fixing block 1, and the pressure relief screw 2 is arranged at the bottom end of the fixing block 1. The fixing block 1 includes an adjusting block 102. An adjusting hole 105 is opened in the middle of the top end of the adjusting block 102, and mounting holes 106 are respectively opened on both sides of the top end of the adjusting block 102. The inner side walls of the two mounting holes 106 are respectively rotatably connected with the fixing screws 3. The bottom end of the adjusting block 102 is fixedly connected with a sleeve 101. The middle of the inner side wall of the top end of the sleeve 101 is fixedly connected with a slider 104, and limiting plates 103 are respectively fixedly connected on both sides of the slider 104. By providing the fixing block 1, the slider 104 and the limiting plates 103 are arranged at the bottom end of the fixing block 1. Through the mutual adaptation of the slider 104 and the limiting plates 103 with the pressure relief screw 2, the adjusting hole 105 is rotated to fix the pressure relief screw 2, which is convenient for the installation of the screw.

[0033] The pressure relief screw 2 includes two threaded blocks 201. Chute grooves 202 are respectively opened at the top ends of the two threaded blocks 201, threaded holes 203 are respectively opened at one side of the top ends of the two threaded blocks 201, and two limiting grooves 204 are respectively arranged between the two threaded blocks 201. Two mounting holes 106 are arranged on the fixing block 1. By screwing the fixing screws 3 into the threaded holes 203 on the threaded blocks 201, the whole pressure relief screw 2 is fixed, which effectively facilitates the good stability of the screw when treating patients. When the device needs to be disassembled, the doctor first fixes the adjusting block 102. By rotating the two fixing screws 3, after the fixing screws 3 are removed, the fixing block 1 is removed. At this time, the gap between the limiting grooves 204 formed between the two threaded blocks 201 effectively removes the threaded blocks 201 directly, effectively alleviating the pain of the patient when removing the screw.

[0034] Both sides of the slider 104 are respectively slidably connected with the inner side walls of the two chute grooves 202, and the cross-sectional areas of the two chute grooves 202 and the slider 104 are equal. The inner diameter of the inner side wall of the sleeve 101 is equal to the diameters of the two threaded blocks 201. The two fixing screws 3 respectively penetrate through the adjusting hole 105 and are threadedly connected with the inner side walls of the two threaded holes 203. The two limiting grooves 204 respectively match with the two limiting plates 103. Threads are respectively arranged on the side walls of the two threaded blocks 201, and the two threaded blocks 201 match with each other. The adjusting block 102 is a hexagonal prism three-dimensional structure.

[0035] Working principle: By setting the fixed block 1, a slider 104 and a limit plate 103 are arranged at the bottom end of the fixed block 1. Through the mutual adaptation of the slider 104 and the limit plate 103 with the pressure relief screw 2, the rotation adjustment hole 105 is used to fix the pressure relief screw 2, which is convenient for the installation of the screw. Two mounting holes 106 are arranged on the fixed block 1. By screwing the fixing screw 3 into the threaded hole 203 on the threaded block 201, the whole pressure relief screw 2 is fixed, effectively facilitating the good stability of the screw when treating the patient. When the device needs to be disassembled, the doctor first fixes the adjustment block 102. By rotating the two fixing screws 3, after the fixing screws 3 are removed, the fixed block 1 is removed. At this time, the gap between the limiting grooves 204 formed between the two threaded blocks 201 is used to effectively remove the threaded block 201 directly, effectively alleviating the pain of the patient when removing the screw.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
