[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specific examples are given below.

[0025] like Figure 1-4As shown, a spinal posterior nail rod surgical instrument package processing and grinding device comprises a driving body 1; a grinding body 11 is installed in the middle of the driving body 1; a placement frame 12 is fixedly connected to the outer wall of the driving body 1; a clamping hole 13 is opened in the middle of the placement frame 12; the grinding body 11 is slidably arranged on the inner wall of the clamping hole 13; a double-axis motor 14 is installed in the middle of the placement frame 12; a fan blade 15 is fixedly connected to the bottom output end of the double-axis motor 14; a catheter 16 is provided in the middle of the placement frame 12; the end of the catheter 16 is fixedly connected to a cleaning The cleaning cylinder 17 is arranged near the output end of the grinding body 11; a plurality of exhaust holes 18 are arranged in the middle of the cleaning cylinder 17; the conduit 16 and the cleaning cylinder 17 are connected; when working, the staff needs to install the driving body 1 at the designated position, place the instrument to be polished in the working area, and hold the middle of the grinding body 11 to polish the instrument. By setting a placement rack 12 on the outer wall of the driving body 1, the staff can align the output end of the grinding body 11 with the card hole 13 in a straight line , and is placed inside the placement frame 12 for support and fixation, and the output end of the grinding body 11 will be close to the cleaning barrel 17. At this time, the switch of the dual-axis motor 14 can be turned on, so that the output end of the dual-axis motor 14 drives the fan blades 15 to rotate, and the fan blades 15 will generate wind after the rotation, and the wind will be discharged downward, so that the wind passes through the duct 16 and the cleaning barrel 17, and is discharged from the middle of the multiple exhaust holes 18, so as to clean the grinding head position at the output end of the grinding body 11. This step is performed by driving the main A placement rack 12 is provided on the outer wall of the body 1, which can be used to store the entire grinding body 11, thereby reducing the problem of directly placing the grinding body 11 on the desktop, which leads to the attachment of more impurities to the grinding head position of the grinding body 11. The wind force discharged from the end of the exhaust hole 18 can improve the cleanliness of the grinding head position of the grinding body 11, reduce the accumulation of more dust or metal chips on the surface of the grinding head after long-term use, thereby affecting the quality of the instrument product after processing, and reduce the need for staff to frequently replace the grinding head in the middle part of the grinding body 11.

[0026] like Figure 2 and 3As shown, the top output end of the dual-axis motor 14 is fixedly connected with a reciprocating screw 2; the middle part of the reciprocating screw 2 is threaded; a slider 21 is connected; a slide groove 22 is opened in the middle of the placement frame 12; the end of the slider 21 is fixedly connected with a limiting rod 23, and the limiting rod 23 is slidably arranged on the inner wall of the slide groove 22; the other end of the limiting rod 23 is fixedly connected to the middle part of the guide tube 16; the guide tube 16 is slidably arranged on the inner wall of the placement frame 12; when working, a reciprocating screw 2 is arranged at the top output end of the dual-axis motor 14, so that when the dual-axis motor 14 is performing normal work, it will synchronously drive the reciprocating screw 2 to rotate, While the reciprocating screw 2 is rotating, the slider 21, under the action of the limiting rod 23, will reciprocate up and down in the middle of the reciprocating screw 2, so that the guide tube 16 slides on the inner wall of the placement frame 12 and increases the area of ​​the cleaning cylinder 17 for cleaning the grinding head. This step, in conjunction with the slider 21, can improve the flexibility of the cleaning cylinder 17 when cleaning the grinding head, reduce the problem that the working position of the original cleaning cylinder 17 is usually fixed, resulting in a part of the grinding head area being difficult to be cleaned by the wind discharged from the end of the exhaust hole 18 when cleaning the grinding head, and reduce the time for cleaning the grinding head.

[0027] like Figure 2 and 4 As shown, a reinforcing member 3 is fixedly connected to the bottom of the conduit 16; a spring 31 is fixedly connected to the bottom of the reinforcing member 3; a connecting rod 32 is fixedly connected to the bottom of the spring 31; a storage box 33 is fixedly connected to the end of the connecting rod 32, and the inner wall of the storage box 33 is concave. During operation, by arranging a spring 31 in the middle of the conduit 16, when the exhaust hole 18 cleans away the impurities attached to the grinding head, most of the impurities will fall on the top of the storage box 33 and be collected on its inner wall. Under the action of the inertia of the up and down movement of the conduit 16 and the shaking force generated by the spring 31, the impurities accumulated inside the storage box 33 can be shaken and flattened. The storage box 33 arranged in this step can collect most of the fallen impurities, reducing the problem of some impurities falling directly to the outside and causing secondary cleaning. The elastic storage box 33 can make the impurities accumulate faster inside the storage box 33 after being collected inside the storage box 33 due to the existence of more gaps between the impurities, thereby increasing the storage space of the storage box 33.

[0028] like Figure 2 and 4As shown, a baffle 4 is fixedly connected to the top of the cleaning cylinder 17, and the inner wall of the baffle 4 is inclined; a brush 41 is fixedly connected to the top of the baffle 4; the inner wall of the brush 41 is in contact with the grinding body 11; during operation, a baffle 4 is provided on the top of the exhaust hole 18, so that when the staff clamps the grinding body 11 on the inner wall of the clamping hole 13, the end of the grinding body 11 will contact the inner wall of the brush 41 first, and some impurities will be scraped and cleaned, and when the exhaust hole 18 is working, the inclined baffle 4 will reduce the problem of part of the wind force being transferred to the outside, and at the same time, some flying impurities can be blocked. This step, in conjunction with the baffle 4, can reduce the problem of dust generated in the exhaust hole 18 during use, and at the same time, in conjunction with the brush 41 in contact with the end of the grinding body 11, the cleanliness of the end of the grinding body 11 can be further improved.

[0029] like Figure 3 As shown, the inner wall of the placement rack 12 is provided with a guide groove 5, and the guide groove 5 is horn-shaped; the guide groove 5 is arranged at the bottom of the fan blade 15; when working, by arranging the guide groove 5 on the inner wall of the placement rack 12, after the fan blade 15 rotates and generates wind force, the wind force will first contact the inner wall of the guide groove 5 and be transferred to the inside of the duct 16 again. This step cooperates with the set guide groove 5 to increase the speed of air flow inside the duct 16, thereby increasing the accuracy of the exhaust hole 18 in cleaning the grinding head.

[0030] like Figure 4 As shown, two sets of counterweights 6 are fixedly connected to the top of the storage box 33, and the top of the counterweights 6 is arc-shaped; when working, the two sets of counterweights 6 are arranged in cooperation, so that when the storage box 33 is in use, the gravity of the two sets of counterweights 6 is used to press the top of the storage box 33. This step cooperates with the two sets of counterweights 6 to improve the stability of the storage box 33 when working, reduce the impurities accumulated on the inner wall of the connecting rod 32, and cause a large shaking amplitude under the action of the spring 31, thereby improving the stability of collecting impurities.

[0031] like Figure 2 and 4 As shown, the inner wall of the storage box 33 is fixedly connected with a friction pad 7; during operation, by providing the friction pad 7 on the inner wall of the storage box 33, when impurities fall on the inner wall of the connecting rod 32, they will contact the surface of the friction pad 7 first. This step cooperates with the provided friction pad 7 to reduce the problem of the wind discharged from the middle of the exhaust hole 18 directly contacting the connecting rod 32, so that the fine impurities accumulated on the inner wall of the connecting rod 32 are lifted up again.

[0032] Working principle: After the driving body 1 is installed at the designated position, the instrument to be polished is placed in the working area, and the middle part of the polishing body 11 is held by hand to polish the instrument. By providing a placement rack 12 on the outer wall of the driving body 1, the staff can align the output end of the polishing body 11 with the card hole 13 in a straight line, and place it inside the placement rack 12 for support and fixation, and the output end of the polishing body 11 will be close to the cleaning barrel 17. At this time, the switch of the dual-axis motor 14 can be turned on, so that the output end of the dual-axis motor 14 drives the fan blades 15 to rotate, and the fan blades 15 will generate wind after rotating, and the wind will be directed to The wind is discharged downward, so that the wind passes through the duct 16 and the cleaning cylinder 17, and is discharged from the middle of the multiple exhaust holes 18, thereby cleaning the grinding head position at the output end of the grinding body 11. A reciprocating screw 2 is provided at the top output end of the dual-axis motor 14, so that when the dual-axis motor 14 is performing normal work, it will synchronously drive the reciprocating screw 2 to rotate, and while the reciprocating screw 2 is rotating, the slider 21 will reciprocate up and down in the middle of the reciprocating screw 2 under the action of the limiting rod 23, thereby causing the duct 16 to slide on the inner wall of the placement frame 12, and increasing the cleaning area of ​​the cleaning cylinder 17 to clean the grinding head. By arranging a spring 31 in the middle of the conduit 16, when the exhaust hole 18 cleans away the impurities attached to the grinding head, most of the impurities will fall on the top of the storage box 33 and be collected on the inner wall thereof. Under the action of the inertia of the up and down movement of the conduit 16 and the shaking force generated by the spring 31, the impurities accumulated inside the storage box 33 can be shaken and flattened. By arranging a baffle 4 on the top of the exhaust hole 18, when the staff clamps the grinding body 11 on the inner wall of the clamping hole 13, the end of the grinding body 11 will contact the inner wall of the brush 41 first and scrape and clean some impurities. When working, the inclined baffle 4 will reduce the problem of transferring part of the wind force to the outside, and at the same time, it can block some flying impurities. By providing a guide groove 5 on the inner wall of the placement frame 12, after the fan blades 15 rotate and generate wind force, the wind force will first contact the inner wall of the guide groove 5 and be transferred to the inside of the duct 16 again. With the two sets of counterweights 6, when the storage box 33 is in use, the gravity of the two sets of counterweights 6 is used to press the top of the storage box 33. By providing a friction pad 7 on the inner wall of the storage box 33, when impurities fall on the inner wall of the connecting rod 32, they will first contact the surface of the friction pad 7.
