DETAILED DESCRIPTION

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The cutting device for amniotic membrane pretreatment according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0033] like Figure 1 Figure 2 Figure 3 Figure 6As shown, the cutting device for amniotic membrane pretreatment according to an embodiment of the present invention may include: a supporting component 1, a transmission component 2, a loading component 3, a cutting component 4 and a cutting box 5.

[0034] It should be noted that the support assembly 1 includes: a support leg 11 and a support sleeve 12, wherein the two support sleeves 12 are respectively mirror-set to the top of the support leg 11.

[0035] It should be further explained that the support leg 11 is rotatably set at the bottom of the two support sleeves 12, and the support sleeve 12 includes: a support ring 121, a first baffle 122 and a second baffle 123, wherein the first baffle 122 and the second baffle 123 are respectively fixedly set in the support ring 121, and the first baffle 122 and the second baffle 123 are parallel to each other, the support ring 121 is sleeved on one side of the loading component 3, and the driving end of the loading component 3 extends to both sides and is rotatably set on the first baffle 122 and the second baffle 123, the first baffle 122 and the second baffle 123 are respectively mirrored with arc grooves 8, and a through-going make way groove 1211 is opened on the support ring 121, and the make way groove 1211 is located between the first baffle 122 and the second baffle 123.

[0036] It can be understood that the rotatable support leg 11 is mirror-set at the bottom of the support sleeve 12. When the support leg 11 is mirror-opened, the support leg 11 will be inclined to provide support force for its support sleeve 12. When the rotatable support leg 11 is retracted, it is convenient to move the present invention, and the support sleeve 12 can provide support force for its transmission component 2, loading component 3 and cutting component 4.

[0037] It can be further understood that the support ring 121 can provide support force for the cutting assembly 4 arranged on the top, and the first baffle 122 and the second baffle 123 arranged therein can provide support force for the feeding assembly 3 and the transmission assembly 2, and the arc groove 8 opened on the first baffle 122 and the second baffle 123 allows the second double gear 22 to move along the arc groove 8 when rotating, and the give way groove 1211 provides movement space for its bar teeth 24.

[0038] Specifically, the loading assembly 3 is rotatably arranged on the opposite surfaces of the two support sleeves 12, the two transmission assemblies 2 are respectively mirror-arranged in the two support sleeves 12, and the transmission assemblies 2 are respectively connected to the moving end of the cutting assembly 4 and the transmission end of the loading assembly 3, and the cutting assembly 4 is fixedly arranged on the top of the two support sleeves 12.

[0039] It should be noted that when the electric telescopic rod 43 is activated, the cutting box 5 inside the rectangular protective sleeve 44 will be limited through the limiting rod 453, and the rectangular cutting knife 45 will cut the amniotic membrane at the top of the cutting box 5.

[0040] It can be understood that when the amniotic membrane is laid flat on the top of the cutting box 5 and the cutting box 5 is placed on the top of the loading assembly 3, when the electric telescopic rod 43 is started, the loading assembly 3 will be driven to work through the transmission assembly 2, so that the cutting box 5 placed on the top of the loading assembly 3 is moved to the bottom of the cutting assembly 4, and the amniotic membrane laid flat on it is cut through the cutting assembly 4.

[0041] like Figure 8 Fig. 9 Fig.10 Fig.11 As shown, the cutting device for amniotic membrane pretreatment according to an embodiment of the present invention may include: a cutting assembly 4 including: a support frame 41, a lifting plate 42, an electric telescopic rod 43, a rectangular protective sleeve 44 and a rectangular cutting knife 45.

[0042] Among them, it should be noted that the support frame 41 is fixedly set on the top of the two support sleeves 12, the lifting plate 42 is movably set inside the support frame 41, and one end of the lifting plate 42 is connected to the moving end of the transmission assembly 2. When the lifting plate 42 moves, it will drive the loading assembly 3 to rotate through the transmission assembly 2. The rectangular protective sleeve 44 is movably set at the bottom of the lifting plate 42, and the rectangular protective sleeve 44 is directly above the loading assembly 3. The rectangular cutting knife 45 is movably set inside the rectangular protective sleeve 44, and one end of the rectangular cutting knife 45 is provided with a blade, and the other end is connected to the lifting plate 42 through a transmission rod 451. The electric telescopic rod 43 is fixedly set on the top of the support frame 41, and the moving end of the electric telescopic rod 43 passes through the support frame 41 and is connected to the top of the lifting plate 42.

[0043] It should be further explained that four slide grooves 441 are respectively opened perpendicularly to each other on the top of the rectangular protective cover 44, four connecting rods 452 are hingedly arranged on the top of the rectangular cutting knife 45, and the other ends of the four connecting rods 452 are respectively hingedly arranged on one side of the limit rod 453, one end of the limit rod 453 is respectively located in the slide groove 441, and the other end extends toward the upper material component 3, and a limit block 4531 is respectively arranged on the top of the limit rod 453, and two guide rods 6 are vertically arranged on the lifting plate 42, wherein one end of the two guide rods 6 is fixedly arranged on the top of the lifting plate 42, and the other end passes through the support frame 41 and extends outward, and the two guide rods 6 are respectively located on both sides of the electric telescopic rod 43, and an ultraviolet lamp 7 is arranged on the inner bottom side wall of the rectangular protective cover 44.

[0044] It can be understood that after the ultraviolet lamp 7 is started, the rectangular cutting knife 45 inside the rectangular protective cover 44 can be sterilized, and when the electric telescopic rod 43 is started, the telescopic end of the electric telescopic rod 43 will push the lifting plate 42 to descend, so that the rectangular protective cover 44 and the rectangular cutting knife 45 arranged at the bottom of the lifting plate 42 will descend together with the lifting plate 42, thereby cutting the amniotic membrane on the cutting box 5 below.

[0045] It can be further understood that when the lifting plate 42 descends, the rectangular protective sleeve 44 arranged on the outside first abuts against the top of the feeding component 3. At this time, the rectangular protective sleeve 44 cannot descend due to the support force provided by the feeding component 3. At this time, the lifting plate 42 will push the rectangular cutting knife 45 to descend through the transmission rod 451, and the descending rectangular cutting knife 45 will pull the four limit rods 453 along the slide groove 441 toward the rectangular cutting knife 45 through the connecting rod 452, and finally fit on the side wall of the rectangular cutting knife 45. The same is true when the lifting plate 42 rises. The connecting rod 452 in the rising rectangular cutting knife 45 is affected by the gravity of the rectangular protective sleeve 44 and will push the four limit rods 453 to move away from the rectangular cutting knife 45.

[0046] like Figure 3 Figure 4 As shown, the cutting device for amniotic membrane pretreatment according to an embodiment of the present invention may include: a transmission assembly 2 includes: a first double gear 21, a second double gear 22, transmission teeth 23 and bar teeth 24.

[0047] Among them, it should be noted that the first double gear 21 and the two ends of the transmission tooth 23 are respectively connected and arranged on the first baffle 122 and the second baffle 123 through the support rod shaft, the two ends of the second double gear 22 are respectively arranged in the two arc grooves 8 through the sliding rod 221, the bar tooth 24 is movably arranged in the give way groove 1211, the first double gear 21 is concentric with the arc groove 8, and the diameter of the first double gear 21 is smaller than the diameter of the arc groove 8.

[0048] It should be further explained that the small gear in the second double gear 22 is meshed with the large gear in the first double gear 21, and the large gear in the second double gear 22 is meshed with the tooth groove 3311 opened by the transmission column 331, the transmission teeth 23 are meshed with the small gear in the first double gear 21, and the bar teeth 24 are meshed with the transmission teeth 23, one end of the bar teeth 24 is fixedly set on one side of the bottom of the lifting plate 42, the center of the first double gear 21 and the center of the transmission column 331 are respectively on the same horizontal line, and the center of the second double gear 22 is obliquely above the center of the first double gear 21.

[0049] It can be understood that the descending lifting plate 42 will press the bar tooth 24 connected to it to move in the give way groove 1211, so that the moving bar tooth 24 drives the transmission tooth 23 to rotate counterclockwise, and the counterclockwise rotating transmission tooth 23 will drive the first double gear 21 to rotate clockwise, and the clockwise rotating first double gear 21 will drive the second double gear 22 to rotate counterclockwise, and the counterclockwise rotating second double gear 22 will move in the arc groove 8 away from the transmission end of the feeding component 3 through the slide rod 221, and when the lifting plate 42 rises, it will drive the second double gear 22 to rotate clockwise, and at this time the second double gear 22 will mesh with the transmission end of the feeding component 3, thereby driving the feeding component 3 to work.

[0050] It can be further understood that, because the transmission tooth 23 is meshed with the small gear of the first double gear 21, and the small gear of the second double gear 22 is meshed with the large gear of the first double gear 21, the force generated by the rotation of the transmission tooth 23 is accelerated, so that the large gear of the second double gear 22 has sufficient power to drive the feeding component 3 to work.

[0051] like Figure 5 As shown, the cutting device for amniotic membrane pretreatment according to an embodiment of the present invention may include: a loading component 3 includes: a conveyor belt 31, a synchronous belt 32, a driving tooth 33 and a driven tooth 34.

[0052] It should be noted that the conveyor belt 31 is located between the two first baffles 122, the outer sides of the two synchronous belts 32 are fixedly arranged on the inner side of the conveyor belt 31 and are located on both sides of the conveyor belt 31, the two driving teeth 33 and the two driven teeth 34 are located at the two ends of the two synchronous belts 32 and mesh with each other, and the opposite surfaces of the two driving teeth 33 and the two driven teeth 34 are connected to each other by fixing rods 9.

[0053] It should be further explained that, on the other side of the two active teeth 33, a transmission column 331 is concentrically arranged, one end of the transmission column 331 is fixedly arranged on the active tooth 33, and the other end passes through the first baffle 122 to extend toward the second baffle 123, and a circle of tooth grooves 3311 is provided at the extended end along the circumference, and on the other side of the two driven teeth 34, a support column 341 is concentrically arranged, one end of the support column 341 is fixedly arranged on the driven tooth 34, and the other end extends toward the second baffle 123, and passes through the first baffle 122 and the second baffle 123, respectively.

[0054] It is understandable that the rotation of the driving tooth 33 drives the synchronous belt 32 to rotate, thereby driving the driven tooth 34 to rotate through the synchronous belt 32. Since the conveyor belt 31 is arranged on two synchronous belts 32, the rotating synchronous belt 32 drives the conveyor belt 31 to rotate.

[0055] It can be further understood that the transmission column 331 and the support column 341 can provide support force for the synchronous belt 32 and the conveyor belt 31, and the transmission column 331 is provided with a tooth groove 3311 at one end close to the second double gear 22, and is meshed with the second double gear 22, so when the second double gear 22 rotates clockwise, it will drive the transmission column 331 to rotate, thereby causing the active tooth 33 to drive the synchronous belt 32 to rotate.

[0056] like Fig.12 As shown, the cutting device for amniotic membrane pretreatment according to the embodiment of the present invention may include: a cutting box 5 includes: a base 51 and a supporting platform 52 .

[0057] It should be noted that the support platform 52 is fixedly arranged on the top of the base 51 , the support platform 52 and the base 51 are respectively rectangular, and the diameter of the support platform 52 is smaller than the diameter of the rectangular cutting knife 45 , and the rectangular cutting knife 45 can cover the base 51 .

[0058] It can be understood that spreading the amniotic membrane flat on the top of the supporting platform 52 can prevent the amniotic membrane from shrinking due to tension, and when the base 51 is at the bottom of the rectangular cutting knife 45, the descending rectangular cutting knife 45 will move the base 51 to the bottom of the rectangular cutting knife 45 through the limiting rod 453, so that the rectangular cutting knife 45 can cut the amniotic membrane spread on the top of the supporting platform 52.

[0059] In order to better understand the present invention, the specific operation process of the present invention is as follows.

[0060] First, the staff spreads the amniotic membrane on the top of the supporting platform 52 in the cutting box 5, and places the cutting box 5 at the center line of the conveyor belt 31 close to the side of the bar teeth 24. At this time, starting the electric telescopic rod 43 will drive the lifting plate 42 to descend, and the descending lifting plate 42 will drive the bar teeth 24 to descend.

[0061] The descending bar teeth 24 will drive the transmission teeth 23 to rotate, and the transmission teeth 23 will drive the first double gear 21 and the second double gear 22 to rotate. At this time, the second double gear 22 rotates counterclockwise, so that it does not mesh with the transmission column 331, and the feeding assembly 3 does not work.

[0062] At this time, when the rectangular protective cover 44 abuts against the top of the conveyor belt 31, the ultraviolet lamp 7 is started to sterilize the rectangular cutting knife 45. When the sterilization is completed, the ultraviolet lamp 7 is turned off and the electric telescopic rod 43 is retracted. At this time, the lifting plate 42 rises, thereby driving the strip teeth 24 to rise.

[0063] The rising bar teeth 24 will drive the transmission teeth 23 to rotate, and the transmission teeth 23 will drive the first double gear 21 and the second double gear 22 to rotate. At this time, the second double gear 22 rotates clockwise, thereby meshing with the transmission column 331, so that its active teeth 33 rotate, thereby rotating the conveyor belt 31, and the cutting box 5 placed on the top of the conveyor belt 31 will move to the bottom of the rectangular protective cover 44 with the conveyor belt 31.

[0064] At this time, the electric telescopic rod 43 stops contracting and descends, and the rectangular protective cover 44 covers the outside of the cutting box 5. During the descent of the rectangular cutting knife 45, the limit rod 453 moving toward the direction of the rectangular cutting knife 45 will move the cutting box 5 to the bottom of the rectangular cutting knife 45. Finally, the descending rectangular cutting knife 45 will cut the amniotic membrane on the cutting box 5.

[0065] At this time, the electric telescopic rod 43 contracts, which drives the conveyor belt 31 to rotate, thereby removing the cut amnion and the cutting box 5 and moving the next amnion laid on the cutting box 5 to the bottom of the rectangular protective sleeve 44.

[0066] In summary, the cutting device for amniotic membrane pretreatment according to the embodiment of the present invention can cut irregular amniotic membrane, which facilitates the subsequent use and preservation of the amniotic membrane and has high efficiency and cutting accuracy.
