For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] like Figure 1 As shown, the vertebral lamina rongeur handle strength testing device provided by the embodiment of the utility model comprises: a handle mounting seat 100, a pusher 200 and a dynamometer 300; the handle mounting seat 100 is used to mount the vertebral lamina rongeur handle 400; the dynamometer 300 is mounted on the movable end of the pusher 200, and the pusher 200 is used to drive the dynamometer 300 to push against the vertebral lamina rongeur handle 400.
[0030] Specifically, the vertebral laminae bone rongeur handle 400 can be fixedly mounted on the handle mounting seat 100, and one end of the vertebral laminae bone rongeur handle 400 can be fixed by the handle mounting seat 100. The pusher 200 can adopt a linear drive slide rail or a hydraulic telescopic cylinder and other devices to drive the dynamometer 300, and the dynamometer 300 is used to push the holding part of the vertebral laminae bone rongeur handle 400. Under a certain thrust, the vertebral laminae bone rongeur handle 400 is checked for deformation or deformation amplitude. When the vertebral laminae bone rongeur handle 400 is not deformed or the deformation amount is less than the allowable deformation size, it can be determined that the hardness of the vertebral laminae bone rongeur handle 400 is qualified, and the vertebral laminae bone rongeur handle 400 mounted on the handle mounting seat 100 is replaced. In this way, the next vertebral laminae bone rongeur handle 400 can be tested, which can replace manual labor to achieve efficient testing of the vertebral laminae bone rongeur handle 400.
[0031] like Figure 1 and Figure 2As shown, in an embodiment of the utility model, the vertebral lamina bone-gnawing forceps handle strength testing device also includes: a slide 500 and a slide rail 600; the slide rail 600 is parallel to the propulsion direction of the propeller 200, the slide 500 is slidably installed on the slide rail 600, and the dynamometer 300 is installed on the slide 500, and the slide 500 is guided by the slide rail 600, thereby ensuring that the thrust is applied to the vertebral lamina bone-gnawing forceps handle 400 along the extension direction of the slide rail 600.
[0032] Furthermore, a shaft frame 310 is installed at the head end of the dynamometer 300 , and a rotating shaft 320 is installed on the shaft frame 310 . The dynamometer 300 is pushed against the vertebral plate bone rongeur handle 400 through the rotating shaft 320 .
[0033] When the slide rail 600 and the vertebral rongeur handle 400 are both arranged horizontally, the dynamometer 300 is pushed against the middle of the vertebral rongeur handle 400. The rotating shaft 320 is rotatably connected to the shaft frame 310, and the axis of the rotating shaft 320 is arranged longitudinally. When the vertebral rongeur handle 400 is bent and deformed, the rotating shaft 320 slides relative to the vertebral rongeur handle 400, and the sliding resistance can be reduced by rotating the rotating shaft 320.
[0034] Furthermore, the handle mounting seat 100 includes a first bearing platform 110 , on which at least two pins 111 are mounted. The two pins 111 are spaced apart along the upper surface of the first bearing platform 110 , and the two pins 111 are respectively inserted into the lamina bone-holding forceps handle 400 .
[0035] It should be noted that the vertebral laminae bone-holding forceps handle 400 is provided with an articulated shaft hole and a slot hole, etc., and at least two pins 111 can be respectively inserted into the articulated shaft hole or the slot hole. The vertebral laminae bone-holding forceps handle 400 is fixed by at least two pins 111, and one of the pins 111 is used as a fulcrum. The other pins 111 can limit the swinging of the vertebral laminae bone-holding forceps handle 400.
[0036] Furthermore, the handle mounting seat 100 further includes a second bearing platform 120; the second bearing platform 120 is spaced apart from the first bearing platform 110, and carries the lamina rongeur handle 400 respectively, so as to prevent the lamina rongeur handle 400 from being deflected under the action of gravity. The dynamometer 300 is pushed against the area of the lamina rongeur handle 400 between the first bearing platform 110 and the second bearing platform 120, and by detecting the deflection and deformation of the lamina rongeur handle 400 relative to the first bearing platform 110, it can be determined whether the hardness of the lamina rongeur handle 400 is qualified.
[0037] In this embodiment, the handle mounting base 100 and the propeller 200 are both mounted on the base 700 , thereby ensuring that the propeller 200 is firmly positioned relative to the handle mounting base 100 .
[0038] In addition, a protective shell 800 is installed on the base 700, and the protective shell 800 covers the propeller 200 and the dynamometer 300. The protective shell 800 shields the moving parts of the propeller 200 and the dynamometer 300, thereby preventing the human body or foreign objects from contacting the moving parts and causing the propeller 200 and the dynamometer 300 to get stuck.
[0039] like Figure 1 As shown, the pusher 200 includes a pneumatic telescopic cylinder 210, and a dynamometer 300 is installed at the movable end of the pneumatic telescopic cylinder 210. The dynamometer 300 can be electrically driven by the pneumatic telescopic cylinder 210 to extend and retract. When the pneumatic telescopic cylinder 210 is extended, the dynamometer 300 can be pushed against the handle 400 of the vertebral plate bone rongeur.
[0040] Furthermore, a pressure regulating valve 220 is installed in the air inlet pipeline of the pneumatic telescopic cylinder 210, and the air inlet pressure of the pneumatic telescopic cylinder 210 can be adjusted through the pressure regulating valve 220, thereby adjusting the thrust value of the pneumatic telescopic cylinder 210. Under the condition that the force value of the dynamometer 300 is 350N, it can be checked whether the vertebral plate rongeur handle 400 is deformed, thereby judging whether the hardness of the vertebral plate rongeur handle 400 is qualified.
[0041] Furthermore, a reversing valve 230 is installed between the pneumatic telescopic cylinder 210 and the pressure regulating valve 220; the air outlet 221 of the pressure regulating valve 220 is fluidically connected to the air inlet 231 of the reversing valve 230, and the first interface 232 and the second interface 233 of the reversing valve 230 are respectively fluidically connected to the pneumatic telescopic cylinder 210, so as to change the direction of the airflow to enable the pneumatic telescopic cylinder 210 to telescope.
[0042] The opening and closing states of the first interface 232 and the second interface 233 can be switched by the reversing valve 230, so as to control the extension or contraction of the pneumatic telescopic cylinder 210. In addition, the excess gas in the reversing valve 230 can be discharged into the air through the silencer port provided in the reversing valve 230, which can not only avoid air pressure overload, but also reduce exhaust noise.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
