[0002] The blade elasticity tester is a precision instrument specifically used to test the elasticity of surgical blade materials. Its core function is to measure the bending and recovery ability of surgical blade materials under the action of force. When testing the elasticity of surgical blades, it is necessary to move the mold column downward so that the mold column and blade are in contact and maintained for ten seconds, and then observe the appearance of the surgical blade.

[0003] When testing surgical blades with existing blade elasticity testers, the surgical blades are usually placed directly inside the base for measurement. When the mold column is reset upward, the surgical blade will pop outward under its own elastic force, which may cause scratches to the operator and pose a safety hazard. Therefore, it is necessary to provide a device to prevent the surgical blade from popping outward after the mold column is reset, so as to protect the operator. Summary of the Invention

[0034] See also Figure 1-4 As shown, this embodiment is a surgical blade elasticity tester, comprising:

[0035] A tester assembly, the tester assembly includes a base 11;

[0036] The movable assembly includes a placement groove 21, a slide groove 22, a slider 23, a limiting column 24, a first telescopic spring 25, a second telescopic spring 26 and a top plate 27;

[0037] A placement slot 21 is provided at the upper end of the base 11, and slide slots 22 are provided at both sides of the upper end of the placement slot 21. A slider 23 is slidably connected to the inner position of the slide slot 22. A limiting post 24 extends upward through the inner portion of the upper end of the base 11. A first telescopic spring 25 is fixedly connected to the bottom position of the upper end of the limiting post 24. A second telescopic spring 26 is fixedly connected to both sides of the placement slot 21. A top plate 27 is fixedly connected to the top position of the second telescopic spring 26.

[0038] The placement groove 21 is used to place the surgical blade, the slide groove 22 is used to guide the slider 23, the slider 23 is used to limit the position of the surgical blade, the limiting post 24 is used to limit the position of the slider 23, the first telescopic spring 25 is used to reset the limiting post 24, and the second telescopic spring 26 is used to reset the top plate 27, and the top plate 27 is used to drive the surgical blade to move upward;

[0039] The tester assembly further includes a screw rod 12, a movable rod 13 and a mold column 14;

[0040] The screw rod 12 is rotatably connected to the inner position of the base 11, the movable rod 13 is threadedly connected to the outer surface position of the screw rod 12, and the mold column 14 is fixedly connected to the outer end position of the movable rod 13;

[0041] The base 11 is used to support the screw rod 12, the screw rod 12 is used to drive the movable rod 13 to move up and down, the movable rod 13 is used to support the mold column 14, and the mold column 14 is used to deform the surgical blade;

[0042] There are fixing holes at both ends of the slider 23 and the base 11, which are opened relative to the limit column 24, and the first telescopic spring 25 is fixedly connected to the upper end of the base 11;

[0043] When the lower end of the limiting post 24 passes through the slider 23 and enters the interior of the base 11, the limiting post 24 can fix the slider 23 inside the slide groove 22;

[0044] The top of the top plate 27 is flush with the bottom of the placement groove 21, and the sliders 23 are located on both sides below the mold column 14;

[0045] When the top of the top plate 27 and the bottom of the placement slot 21 are flush with each other, the surgical blade is placed at the top of the top plate 27 and the bottom of the placement slot 21 respectively;

[0046] Working principle: When conducting an elasticity test on a surgical blade, the surgical blade is placed inside the placement groove 21, and an upward pulling force is applied to the limiting post 24, so that the limiting post 24 drives the first telescopic spring 25 to stretch upward. When the limiting post 24 moves to the upper end of the base 11, a moving force is applied to the slider 23, so that the slider 23 moves along the slide groove 22. When the slider 23 moves to a position below the limiting post 24, the force applied to the limiting post 24 is stopped, so that the limiting post 24 moves downward under the elastic force of the first telescopic spring 25 and enters the interior of the two ends of the slider 23, so that the limiting post 24 fixes the slider 23 inside the slide groove 22. The slider 23 blocks the upper end of the surgical blade, thereby preventing the surgical blade from popping out after the mold post 14 is reset.

[0047] When the surgical blade needs to be taken out after testing, an upward force is applied to the upper limit post 24 so that the limit post 24 does not block the slider 23, and the slider 23 moves outward without blocking the surgical blade, so that the surgical blade and the top plate 27 move upward under the drive of the second telescopic spring 26. When the surgical blade and the top plate 27 move to above the placement slot 21, the surgical blade can be taken and placed.

[0048] See also Figure 5 and Figure 6 As shown, this embodiment is based on the above embodiment and also includes:

[0049] Detection assembly, which includes a fixed box 31, a guide column 32, a limit plate 33, a fixed disc 34, a screw 35, a rotating disc 36 and a movable plate 37;

[0050] The fixed box 31 is fixedly connected to one side of the base 11, the guide column 32 is fixedly connected to both sides of the upper end of the fixed box 31, the limit plate 33 is sleeved on the outer surface of the guide column 32, the fixed disc 34 is sleeved on the inner position of the limit plate 33, the screw 35 is fixedly connected to the outer position of the fixed disc 34, the rotating disk 36 is fixedly connected to the outer position of the screw 35, and the movable plate 37 is slidably connected to the bottom end of the fixed box 31;

[0051] The fixed box 31 is used to support the guide column 32 and the screw 35. The guide column 32 is used to guide the limit plate 33 and measure the distance between the limit plate 33 and the outer side of the base 11. The limit plate 33 is used to limit the outer side of the surgical blade. The fixed disk 34 is used to drive the limit plate 33 to move. The screw 35 is used to drive the fixed disk 34 to move. The rotating disk 36 is used to drive the screw 35 to rotate. The movable plate 37 is used to remove the surgical blade outward.

[0052] One end of the guide post 32 is fixedly connected to the two ends of one side of the base 11, and there are scale lines on the outer surface of the guide post 32;

[0053] The screw rod 35 extends outward through the fixing box 31, and a threaded structure is provided at the center of the fixing box 31 relative to the screw rod 35.

[0054] By rotating the turntable 36, the turntable 36 can drive the screw 35 to rotate. The screw 35 rotates and moves horizontally under the drive of the thread structure, and drives the fixed disc 34 to rotate and move horizontally.

[0055] Working principle: After the elasticity test of the surgical blade, in order to measure the elasticity of the surgical blade, a rotational force is applied to the turntable 36, so that the turntable 36 drives the screw 35 to rotate, and the screw 35 rotates and moves horizontally under the drive of the thread structure, and the screw 35 drives the fixed disc 34 to rotate and move horizontally. The fixed disc 34 rotates inside the limit plate 33 and drives the limit plate 33 to move horizontally along the guide column 32. According to the scale line on the outer surface of the guide column 32, the limit plate 33 and the outer side of the base 11 maintain a certain distance. At this time, The surgical blade is placed vertically between the limit plate 33 and the base 11. If the surgical blade is blocked by the upper end of the limit plate 33 and the upper end of the base 11 and cannot move downward to the upper end of the movable plate 37, it means that the elasticity of the surgical blade does not meet the requirements. When the surgical blade is not blocked by the upper end of the limit plate 33 and the upper end of the base 11 and moves directly downward to the upper end of the movable plate 37, it means that the elasticity of the surgical blade meets the requirements. By applying an outward pulling force to the movable plate 37, the movable plate 37 moves outward, driving the surgical blade outward, and the surgical blade can be taken out.
