[0024] During operation, the existing protective cover fixing structure of the ultrasonic handle for vaginal ultrasound is not convenient for rapid replacement of the protective cover, the operation is cumbersome, and the protective cover is easily damaged during use, which can easily cause cross infection. In this solution, in the initial state, the torsion spring 12 will always twist the rotating shaft 9, so that the rotating shaft 9 drives the end of the swing rod 10 equipped with the arc-shaped rubber clip 11 to approach the probe 1, thereby making the arc-shaped rubber clip 11 clamped in the clamping groove 16, and making the ends of the two swing rods 10 equipped with the connecting rod 17 tilted. In the initial state, the spring 7 will always push the sliding shell 3 toward the end opposite to the handle 2, so that the sliding shell 3 always remains on the outside of the two groups of clamping components, and the annular limit plate 5 and the No. 1 The fixing rings 6 fit together, so that the two hollow sleeves 14 are kept on the outside of the two swing rods 10, and the two hollow sleeves 14 are respectively located on the outside of the fixed hollow shafts 8 in the two groups of clamping assemblies. During normal operation, the medical staff holds the handle 2 for operation, and first moves the sliding shell 3 toward the side of the handle 2. When the sliding shell 3 moves, it squeezes the spring 7 toward the side of the No. 1 fixing ring 6 to make it contract. After the spring 7 contracts, the No. 1 sleeve 4 will drive the annular limit plate 5 to move into the cavity of the handle 2, and when the sliding shell 3 moves, it will drive the two hollow sleeves 14 through the two fixed shafts 13 to move from the middle sections of the two swing rods 10 in the two groups of clamping assemblies to the side of the connecting rod 17. At this time, since the swing rod 10 is arranged in an inclined manner. When the hollow sleeve 14 moves, it will gradually squeeze the tilted end of the swing rod 10 inwardly. After being squeezed, the tilted end of the swing rod 10 will rotate through the rotating shaft 9, thereby making the end of the swing rod 10 equipped with the arc-shaped rubber clip 11 tilted, and then the arc-shaped rubber clip 11 moves out of the card slot 16. At this time, the protective sleeve can be put on the probe 1, and the protective sleeve is put on the outside of the rubber fixing ring 15. After the protective sleeve is put on, the sliding shell 3 is released. At this time, under the action of the spring 7, the sliding shell 3 will be moved back to the outside of the two groups of clamping components, and the two hollow sleeves 14 will be moved back to the outside of the two fixed hollow shafts 8 in the two groups of clamping components, and at this time, the torsion spring 1 2, the arc-shaped rubber clip 11 will be re-clamped in the slot 16, and because the protective sleeve is now sleeved outside the rubber fixing ring 15, the arc-shaped rubber clips 11 in the two sets of clamping assemblies will fix the protective sleeve to the outside of the probe 1 under the action of the torsion spring 12, thereby fixing the protective sleeve. When replacement is needed, it is only necessary to pull the sliding shell 3 again to make the hollow sleeve 14 squeeze the raised end of the swing rod 10 inward again to remove the arc-shaped rubber clip 11 from the slot 16, and the protective sleeve can be removed for replacement. The cooperation achieves the effect of easy replacement, is more convenient to use than the traditional vaginal ultrasound handle, and effectively avoids cross infection caused by damage to the protective sleeve due to improper operation.

[0025] Working principle: in the initial state, the torsion spring 12 will always twist the rotating shaft 9, so that the rotating shaft 9 drives the end of the swing rod 10 equipped with the arc rubber clip 11 to approach the probe 1, so that the arc rubber clip 11 is clamped in the clamping groove 16, and the ends of the two swing rods 10 equipped with the connecting rod 17 are tilted. In the initial state, the spring 7 will always push the sliding shell 3 toward the end opposite to the handle 2, so that the sliding shell 3 is always maintained on the outside of the two groups of clamping components, and the annular limit plate 5 is fitted with the No. 1 fixing ring 6, so that the two hollow sleeves 14 are maintained on the outside of the two swing rods 10, and the two hollow sleeves 14 are respectively located at the two groups of clamping components. On the outside of the fixed hollow shaft 8 in the assembly, during normal operation, the medical staff holds the handle 2 to operate, first moves the sliding shell 3 toward the side of the handle 2, and when the sliding shell 3 moves, it will squeeze the spring 7 toward the side of the No. 1 fixed ring 6 to make it contract. After the spring 7 contracts, the No. 1 sleeve 4 will drive the annular limit plate 5 to move into the cavity of the handle 2, and when the sliding shell 3 moves, it will drive the two hollow sleeves 14 through the two fixed shafts 13 to move from the middle sections of the two swing rods 10 in the two groups of clamping assemblies to the side of the connecting rod 17. Since the swing rod 10 is tilted at this time, the swing rod 10 will be gradually squeezed inward during the movement of the hollow sleeve 14. The tilted end of the swing rod 10 is squeezed and rotated through the rotating shaft 9, so that the end of the swing rod 10 equipped with the arc-shaped rubber clip 11 is tilted, and the arc-shaped rubber clip 11 is moved out of the card slot 16. At this time, the protective sleeve can be put on the probe 1, and the protective sleeve is put on the outside of the rubber fixing ring 15. After the protective sleeve is put on, the sliding shell 3 is released. At this time, the sliding shell 3 will be moved back to the outside of the two groups of clamping components under the action of the spring 7, and the two hollow sleeves 14 will be moved back to the outside of the two fixed hollow shafts 8 in the two groups of clamping components. At this time, the arc-shaped rubber clip 11 will be clamped again under the action of the torsion spring 12 It is arranged in the slot 16, and because the protective sleeve is arranged outside the rubber fixing ring 15 at this time, the arc-shaped rubber clip 11 in the two sets of clamping assemblies will fix the protective sleeve on the outside of the probe 1 under the action of the torsion spring 12, and then fix the protective sleeve. When replacement is needed, it is only necessary to pull the sliding shell 3 again to make the hollow sleeve 14 squeeze the raised end of the swing rod 10 inward again to remove the arc-shaped rubber clip 11 from the slot 16, and the protective sleeve can be removed for replacement. The cooperation achieves the effect of easy replacement. Compared with the traditional vaginal ultrasound handle, it is more convenient to use and effectively avoids cross infection caused by damage to the protective sleeve due to improper operation.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
