[0036] As Figures 6 - 12 shown, this example can achieve the effect of conveniently passing the cylinder 101 accurately through the tympanic membrane through the tapered ring 105.
[0037] Since the tympanic membrane stent preparation device includes an inner block 307, the inner block 307 is cylindrical, the upper part of the inner block 307 is conical, and two jackets 401 are arranged on both sides of the inner block 307. The upper part of the jacket 401 is conical. The two jackets 401 form a complete sleeve, and a mold groove is formed between the sleeve and the inner block 307. Silicone can be poured into the mold groove to form a deformable cylinder 101 with elasticity. And a tapered ring 105 is arranged on the upper part of the cylinder 101. Through the tapered ring 105, the cylinder 101 can be conveniently passed through the tympanic membrane accurately to effectively support the tympanic membrane and facilitate the drainage of middle ear effusion.
[0038] As Figures 6 - 12 shown, this example can achieve the effect of conveniently fixing the inner block 307 and the two jackets 401.
[0039] Since a first lug 309 is welded to the lower side of the inner block 307, and second lugs 404 are welded to the lower sides of the two outer sleeves 401, the first lug 309 and the two second lugs 404 are inserted into the flat plate 301 with a clearance fit. The inner block 307 and the two outer sleeves 401 can be conveniently fixed by the first lug 309 and the two second lugs 404, and then the silica gel can be conveniently poured into the mold cavity.
[0040] As Figures 6 - 12 shown, this example can achieve the effect of preventing the first lug 309 and the two second lugs 404 from being pulled out.
[0041] Since legs 302 are welded to the four corners of the lower side of the flat plate 301, and the stop bar 308 passes horizontally through the first lug 309 and the two second lugs 404, the four legs 302 support the flat plate 301. When the stop bar 308 passes horizontally through the first lug 309 and the two second lugs 404, the first lug 309 and the two second lugs 404 can be prevented from being pulled out.
[0042] As Figures 9 - 10 shown, this example can achieve the effect of forming four hole strips 106 on the inner side of the cylinder 101.
[0043] Since four vertical grooves 304 are annularly arranged on the outer periphery of the inner block 307, and four round rods 303 are fixed to the upper side of the flat plate 301, the four round rods 303 are respectively inserted into the four vertical grooves 304. After the silica gel is poured into the mold cavity, it can enter the four vertical grooves 304, and hole strips 106 are formed at the four vertical grooves 304 and the four round rods 303, and then four hole strips 106 are formed on the inner side of the cylinder 101.
[0044] As Figures 11 - 12 shown, this example can achieve the effect of forming two circular rings 103 on the cylinder 101.
[0045] Since two annular grooves 402 are provided on the inner side of the outer sleeve 401, and a plurality of convex plates 403 are fixed on each annular groove 402. After the silica gel is poured into the mold cavity, it can enter the two annular grooves 402, and then two circular rings 103 are formed on the cylinder 101. Since a plurality of convex plates 403 are provided on the annular groove 402, a plurality of grooves 102 can be formed at the circular rings 103.
[0046] As Figures 6 - 12 shown, this example can achieve the effect of forming two leakage holes 104 at the tapered ring 105.
[0047] Since a square column 306 is inserted into the upper part of the inner block 307 with a horizontal clearance fit, the square column 306 is inserted into the two outer sleeves 401 with a clearance fit, and retaining pins 305 are inserted into the left and right ends of the square column 306 with a clearance fit. The retaining pins 305 can prevent the square column 306 from sliding randomly, and the square column 306 can fill the mold cavity, so that two leakage holes 104 are formed at the tapered ring 105.
[0048] As Figures 3 - 4 shown, this example can achieve the effect of preventing the cylinder 101 from moving randomly on the eardrum.
[0049] Since the eardrum bracket includes the cylinder 101, a conical ring 105 is provided at one end of the cylinder 101, and two circular rings 103 are provided on the cylinder 101. The conical ring 105 can facilitate the passage of the cylinder 101 on the eardrum bracket through the eardrum. The two circular rings 103 are respectively blocked on the inner and outer sides of the eardrum to prevent the cylinder 101 from moving randomly on the eardrum. The accumulated fluid in the tympanic cavity can be drained through the cylinder 101.
[0050] As Figures 3 - 4 shown, this example can achieve the effect of draining the accumulated fluid in the tympanic cavity faster.
[0051] Since two leakage holes 104 are provided at the conical ring 105, and a plurality of grooves 102 are annularly provided on the circular ring 103, the two leakage holes 104 can make it more convenient for the accumulated fluid in the tympanic cavity to flow into the cylinder 101 and drain the accumulated fluid in the tympanic cavity faster. The plurality of grooves 102 can prevent slipping between the circular ring 103 and the eardrum and avoid random rotation of the cylinder 101 on the eardrum.
[0052] As Figure 5 shown, this example can achieve the effect that the cylinder 101 is elastically reduced, and then after the cylinder 101 is inserted into the eardrum, the four support rods 208 expand, so that the cylinder 101 is elastically expanded and inserted on the eardrum.
[0053] Since there are four hole strips 106 provided on the inner side of the cylinder 101, four support rods 208 are respectively inserted at the four hole strips 106. Sliders 202 are welded to the ends of the four support rods 208. The four sliders 202 are respectively slidably connected to the four ends of the cross 201. A cross bar 206 is welded to the cross 201. A sliding sleeve 207 is slidably connected to the cross bar 206. Four hinge rods 203 are hinged to the sliding sleeve 207. The other ends of the four hinge rods 203 are respectively hinged to the four sliders 202. A connecting plate 205 is welded to the end of the cross bar 206. An electric telescopic rod 204 is fixed to the connecting plate 205. The movable end of the electric telescopic rod 204 is fixed to the sliding sleeve 207. The connecting plate 205 can be fixed to the robotic arm, thus facilitating the movement of the cross bar 206 and the cross 201 to the required positions. By means of the electric telescopic rod 204, the sliding sleeve 207 can be driven to slide on the cross bar 206, and then the four sliders 202 can be respectively driven by the four hinge rods 203 to slide and expand or converge on the cross 201, and further drive the four support rods 208 to expand or converge. Before inserting the cylinder 101 into the ear, the four support rods 208 are respectively inserted into the four hole strips 106 on the cylinder 101, and then the four support rods 208 are driven to converge, so that the cylinder 101 is elastically reduced. Then, after the cylinder 101 is inserted onto the eardrum, the four support rods 208 are expanded, so that the cylinder 101 is elastically expanded and inserted onto the eardrum.
