The piston 802 is slidably connected to the inclined plate 804, and the inclined plate 804 is fixed to the fixed plate 5. The liquid inlet on the liquid box 801 is connected to the liquid replenishing box 805 through a conduit. The liquid replenishing box 805 is fixed to the liquid box 801, and the liquid outlet on the liquid box 801 is connected to the expansion cylinder 10 through a conduit. The liquid box 801 is connected to each other, and a sealing structure 9 is provided on the side of the liquid inlet of the liquid box 801. The sealing structure 9 includes a fixing frame 901, a sliding rod 902, a sealing ball 903 and a third spring 904. The fixing frame 901 is fixed in the liquid box 801, and the fixing frame 901 is slidably connected with the sliding rod 902. The sealing ball 903 is fixed on the sliding rod 902. The sealing ball 903 cooperates with the liquid inlet of the liquid box 801 to achieve sealing.

By adjusting the position of the piston 802, the amount of liquid injected into the expansion cylinder 10 can be adjusted. After the adjustment is completed, when testing is performed, the cylinder 4 is controlled to extend to drive the fixed plate 5 and the detection mechanism 6 to move downward, thereby driving the inclined plate 804 to move downward. When the inclined surface of the inclined plate 804 contacts and slides with the piston 802, the piston 802 is forced to move, so that the liquid in the liquid box 801 passes through the expansion cylinder 10. When the plane of the inclined plate 804 contacts and slides with the piston 802, the expansion cylinder 10 is completed. 0, so that the expansion cylinder 10 maintains a fixed hardness for subsequent testing. When the test is completed, the inclined plate 804 is driven upward by the contraction of the cylinder 4. When the inclined plate 804 is separated from the piston 802, the elastic effect of the second spring 803 can make the liquid in the expansion cylinder 10 flow back into the liquid box 801, so as to realize the reuse of the liquid. When part of the liquid remains in the expansion cylinder 10 and cannot flow back, the movement of the piston 802 forms a negative pressure in the liquid box 801. Under the action of negative pressure, the sealing ball 903 is separated from the liquid inlet on the liquid box 801, thereby releasing the sealing effect, so that the liquid in the liquid replenishing tank 805 enters the liquid box 801 through the liquid inlet on the catheter liquid box 801, and the liquid in the liquid box 801 is replenished, ensuring that the liquid in the liquid box 801 is always in a full state, so as to facilitate subsequent detection. After the liquid in the liquid box 801 is replenished, the sealing ball 903 can be reset to seal the liquid inlet on the liquid box 801 with the action of the third spring 904; Detection mechanism 6, mounting plate 601, pressure head 602, first spring 603, pressure sensor 604, vertical rod 605, limit plate 606, movable plate 607, guide rod 608 and high-precision laser rangefinder 609, mounting plate 601 is arranged below fixed plate 5, and pressure head 602 is fixed on the lower end surface of mounting plate 601, and one end of first spring 603 is fixed on mounting plate 601, and the other end of first spring 603 is fixed on pressure sensor 604, The pressure sensor 604 is fixed to the lower end surface of the fixed plate 5, the distance between the pressure head 602 and the expansion cylinder 10 is greater than the height of the inclined surface of the inclined plate 804, and the lower end surface of the pressure head 602 is flush with the lower end surface of the inclined plate 804; the mounting plate 601 is also symmetrically fixed with a vertical rod 605, and the vertical rod 605 is slidably connected to the fixed plate 5, and a limit plate 606 is fixed on the vertical rod 605, and the limit plate 606 contacts the fixed plate 5 to achieve positioning; the pressure head 602 and The movable plates 607 are connected in a sliding manner, and the lower end surface of the movable plate 607 is flush with the lower end surface of the pressure head 602; a guide rod 608 is fixed on the movable plate 607, and the guide rod 608 is connected in a sliding manner to the mounting plate 601; a high-precision laser rangefinder 609 is arranged directly above the guide rod 608, and the high-precision laser rangefinder 609 is fixed on the lower end surface of the fixed plate 5, and the high-precision laser rangefinder 609 and the guide rod 608 are distributed in a one-to-one correspondence; the adjustment mechanism 7 includes The threaded rod 701, the movable block 702, the movable platform 703 and the fixed rod 704, the threaded rod 701 is connected to the bottom plate 1 by a bearing, the threaded rod 701 is connected to the movable block 702 by a thread, the movable block 702 is fixed on the movable platform 703, and the liquid box 801 is fixed on the movable platform 703; the movable block 702 and the fixed rod 704 are slidably connected, and the fixed rod 704 is fixed on the bottom plate 1, and the length of the fixed rod 704 is less than the width of the inclined plate 804; During the testing process, if Figure 1-Figure 7As shown, when the plane of the inclined plate 804 contacts the piston 802, the pressure head 602 and the movable plate 607 just contact the expansion cylinder 10, and the cylinder 4 continues to extend to drive the fixed plate 5 to move downward, so that the pressure head 602 continues to move downward to apply pressure to the expansion cylinder 10, and with the elastic effect of the first spring 603, during the downward pressure detection process, when the pressure head 602 is blocked and cannot move downward, the fixed plate 5 will be forced to move relative to the mounting plate 601, and with the sliding guide effect between the vertical rod 605 and the fixed plate 5, the stability of the movement of the fixed plate 5 can be guaranteed until the fixed plate 5 contacts the limit plate 606. At this time, the cylinder 4 stops extending, and the first spring 603 is in a contracted state. The elastic effect of the first spring 603 can apply a force to the pressure head 602, so that the pressure head 602 applies pressure to the expansion cylinder 10, and because the contraction length of the first spring 603 is fixed, The pressure applied by the pressure head 602 to the expansion cylinder 10 is also fixed, so as to realize the constant pressure detection function. With the action of the pressure sensor 604, the pressure size can be determined. When the pressure head 602 applies pressure to the expansion cylinder 10 and causes the expansion cylinder 10 to be concave, the movable block 702 moves upward relative to the pressure head 602, so that the distance between the movable block 702 and the mounting plate 601 is reduced. With the sliding guide action between the guide rod 608 and the mounting plate 601, the stability of the movement of the movable block 702 can be guaranteed. When the guide rod 608 slides, with the action of the high-precision laser rangefinder 609, the moving distance of the guide rod 608 can be detected, so that the concave distance of the expansion cylinder 10 can be determined, and then the hardness of the expansion cylinder 10 can be calculated, thereby realizing the hardness detection function of the expansion cylinder 10. This is the working principle of the inflatable reproductive prosthesis and its hardness detection device.
