[0002] Allogeneic bone implants are a type of biomaterial used in orthopedic treatments. They originate from individuals of the same species as the recipient but are different from the recipient. They are primarily used in orthopedic surgeries, such as filling bone defects, supporting fracture healing, and filling bones in joint replacements. During surgical use, allogeneic bone is typically sterilized to reduce rejection and improve postoperative recovery.

The utility model has the advantage of increasing the adequacy of sterilization of allogeneic bone implant materials;

[0004] The above-mentioned existing technical solution has the following shortcomings: the device uses the rotation of the rotating roller to flip the heterotopic bone located on the rotating roller, thereby achieving uniform heating and sterilization of the heterotopic bone. However, in this structure, due to the structural characteristics of the bone shape, the contact angle between the bone surface and the rotating roller is different, and thus the stability of the bone during the flipping process cannot be guaranteed. Moreover, since the bone is thick at both ends and thin in the middle, the contact area between the heterotopic bone and the rotating roller is limited, so it cannot be guaranteed that the heterotopic bone will definitely flip, and it is difficult to ensure that the heterotopic bone and the steam discharged from the air vent can be evenly contacted and heated. Therefore, there is room for improvement. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) By utilizing the transpiration effect of the hot steam in the sterilization tank and cooperating with the steam circulation component A, the rotating shaft inside the circulation drum generates a high speed rotation to form a downward suction force, thereby sucking the hot steam into the circulation drum, and cooperating with the action of the steam circulation component B, the hot steam is discharged at high speed along the air guide pipe 2, thereby realizing the circulation flow of the hot steam from outside to inside and from right to bottom in the sterilization tank, while promoting the flow of the hot steam and enabling the hot steam to evenly heat the surface of the ectopic bone along the length direction of the ectopic bone;

[0019] Under the exhaust action of the second air guide pipe and the exhaust hood, the hot steam generates a driving force on the self-rotating fan blades, so that the self-rotating fan blades drive the limiting cylinder to rotate, thereby realizing the self-rotation of the heterotopic bone, thereby changing the relative position between the heterotopic bone and the exhaust hole, thereby further promoting the uniform heat sterilization effect on the surface of the heterotopic bone;

[0020] As the circulation drum rotates, it drives the multiple heterotopic bones to rotate horizontally, thereby further promoting the horizontal rotation of the hot steam in the sterilization tank. Combined with the flow effect of the hot steam, the hot steam forms a spiral rise outside the circulation drum, so that the spiral rising steam can easily move the fire-killing bacteria or stains on the heterotopic bones into the interior of the circulation drum, thereby improving the sterilization effect on the surface of the heterotopic bones.

[0021] (2) By cooperating with the limiting cylinder, the movable clamping block and the fixed clamping block, one end of the heterotopic bone of the same kind can be clamped and fixed to the left and right, thereby preventing the heterotopic bone from moving randomly during the rotation process. At the same time, the inert gas in the airbag sleeve is filled to increase the contact tightness between the limiting cylinder and one end of the heterotopic bone, thereby improving the fixation effect of the heterotopic bone;

[0022] The thermal conductivity of the limiting tube material is utilized to cause the airbag sleeve to expand to a certain extent when heated, which on the one hand improves the fixation effect, and on the other hand utilizes the heat conduction of the inert gas to facilitate high-temperature sterilization of the fixed end of the ectopic bone.

[0034] Example 1

[0035] In order to solve the problem that it is difficult to ensure uniform heat contact of steam on the allogeneic solid surface during sterilization of the existing allogeneic bone implant materials, the following solution is disclosed. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 、 Figure 5 As shown:

[0036] A sterilization device for producing allogeneic bone implant materials, comprising a sterilization box 1, a sterilization tank 2 is provided at the top of the sterilization box 1, and a sealing cover 4 is provided at the top of the sterilization box 1 above the sterilization tank 2, a cavity 3 is provided at the bottom end of the sterilization box 1, and a heat-insulating motor 15 is installed on one side of the bottom end of the cavity 3, a driving gear 16 is installed at the output end of the heat-insulating motor 15, the bottom end of the sterilization tank 2 is rotatably connected to a rotating seat 13, and the bottom end of the rotating seat 13 extends to the interior of the sterilization tank 2 and is installed with a driven gear 17, one side of the driven gear 17 is meshed with one side of the driving gear 16, and the diameter of the driven gear 17 is smaller than that of the driving gear 16. The diameter of the moving gear 16 is 0.13 mm. A circulation drum 10 is installed on the top of the rotating seat 13, and a steam circulation component A18 is provided inside the circulation drum 10, so that hot steam flows from the upper end to the lower end of the circulation drum 10. Four connecting blocks 22 are evenly spaced at the bottom end of the outer side of the circulation drum 10, and one end of each connecting block 22 is installed with a limiting drum 12. The interior of the limiting drum 12 is sleeved with an ectopic bone fixing mechanism, and the bottom end of the ectopic bone fixing mechanism is connected to the outer side of the circulation drum 10 with a steam circulation component B14. The inner wall of the sterilization tank 2 is provided with a steam pipe 5, and the steam pipe 5 is spiral. At the same time, exhaust holes 6 are evenly spaced on the inner side of the steam pipe 5;

[0037] An air inlet pipe 8 is installed at the top of the steam pipe 5, and an exhaust pipe 9 is installed at the bottom of the steam pipe 5. Both the exhaust pipe 9 and the air inlet pipe 8 extend to the outside of the sterilization box 1 and are installed with a control valve. A pressure equalizing pipe 7 is connected to one side of the sterilization box 1;

[0038] The steam circulation component B14 includes an air guide pipe 1401 installed on the outside of the circulation cylinder 10, and three air guide pipes 1402 are evenly installed on the outside of the air guide pipe 1401 away from one end of the circulation cylinder 10, and an exhaust hood 1403 is installed on the top of each air guide pipe 1402. Six rotating fan blades 1404 are evenly distributed in a ring at the bottom end of the outside of the ectopic bone fixation mechanism. The top of the exhaust hood 1403 faces directly below the rotating fan blades 1404. The diameter of the air guide pipe 1401 is larger than the diameter of the air guide pipe 1402, so as to accelerate the flow rate of the hot steam discharged upward and increase the impact force of the hot steam on the rotating fan blades 1404, so as to realize the self-rotation of the ectopic bone fixation mechanism.

[0039] The steam circulation assembly A18 includes a rotating shaft 1804 that passes through the interior of the circulation drum 10, and the bottom end of the rotating shaft 1804 extends to the interior of the sterilization tank 2. The rotating shaft 1804 is rotatably connected to the circulation drum 10. The bottom end of the rotating shaft 1804 is installed with a gear 2 1803. The bottom end of the driving gear 16 is coaxially installed with a gear 1 1801. The bottom end of the interior of the sterilization tank 2 is installed with a transmission gear 1802. One side of the transmission gear 1802 is meshed with one side of the gear 1 1801, and the other side of the transmission gear 1802 is meshed with one side of the gear 2 1803. The outer wall of the top end of the rotating shaft 1804 is evenly installed with suction fan blades 1805.

[0040] The diameter of gear 1 1801 is smaller than that of driving gear 16 , and gear 1 1801 , transmission gear 1802 , and gear 2 1803 have the same diameter, that is, the rotation speed of the suction fan blade 1805 is greater than the rotation speed of the circulation drum 10 ;

[0041] The length of the circulation cylinder 10 is smaller than the height of the sterilization tank 2 , and the suction fan blades 1805 are close to the top of the circulation cylinder 10 .

[0042] In this embodiment, when in use, the sealing cover 4 is opened, the heterotopic bone of the same kind is inserted into the interior of the limiting cylinder 12 and fixed, the control valve of the air inlet pipe 8 is started, the hot steam flows along the steam pipe 5, and is discharged into the sterilization tank 2 along the exhaust hole 6. The distribution of the exhaust hole 6 is utilized to evenly distribute the hot steam inside the sterilization tank 2, and at the same time, the heat-insulating motor 15 is started to rotate the driving gear 16 and drive the driven gear 17 to rotate, so that the rotating seat 13 drives the circulation cylinder 10 to rotate, so that the heterotopic bone rotates, so as to change the relative position between the heterotopic bone and the exhaust hole 6, and improve the heating uniformity of the surface of the heterotopic bone. At the same time, the rotation of the driving gear 16 is utilized to rotate the gear 1 1801, and under the meshing of the transmission gear 1802 and the gear 2 1803, the rotating shaft 18 04 drives the suction fan blades 1805 to rotate at high speed, thereby increasing the air flow speed at the top of the circulation cylinder 10 to form a negative pressure, thereby absorbing the hot air evaporating upward, and then discharging the hot air outward through the air guide tube 1401. At the same time, the change in the diameter of the air guide tube 1401 and the air guide tube 2 1402 is used to increase the rate of hot air discharge. By using this circulation method, the flow of hot steam inside the sterilization tank 2 is increased, thereby promoting the uniform contact between the hot steam and the surface of the ectopic bone, and improving the comprehensiveness of the sterilization. At the same time, due to the upward jet of the exhaust hood 1403, the rotating fan blades 1404 rotate under the action of the air flow, causing the limiting cylinder 12 to rotate while rotating, thereby further promoting the uniform heating of the surface of the ectopic bone and improving the comprehensiveness and efficiency of the sterilization.

[0043] Example 2

[0044] This embodiment is different from the first embodiment in that an ectopic bone fixing mechanism is used to prevent the ectopic bone from moving during rotation and improve the stability of the ectopic bone. Figure 1 、 Figure 4 、 Figure 6 and Figure 7 、 Figure 8 As shown:

[0045] The ectopic bone fixation mechanism includes a sliding ring 21 sleeved inside the fixed guide ring 11, and the interior of the sliding ring 21 passes through the limiting cylinder 12, the bottom end of the limiting cylinder 12 is installed with an airbag sleeve 20, and the inner wall of the limiting cylinder 12 above the airbag sleeve 20 is provided with a clamping assembly 19;

[0046] The limiting cylinder 12 forms a rotating structure with the fixed guide ring 11 through the cooperation of the sliding ring 21. The outer side of the bottom end of the limiting cylinder 12 is welded to the inner side of the rotating fan blade 1404. The diameter of the limiting cylinder 12 is larger than the maximum diameter of the ectopic bone.

[0047] The limiting cylinder 12 is made of copper, and the surface of the limiting cylinder 12 is provided with a waterproof coating, and the interior of the airbag cover 20 is filled with an inert gas;

[0048] The clamping assembly 19 includes a fixed clamping block 1904 mounted on the top of one side of the inner limit tube 12. An adjusting rod 1902 is inserted through the inner wall of the limit tube 12 opposite the fixed clamping block 1904. A movable clamping block 1901 is mounted on the inner end of the adjusting rod 1902, and a butterfly block 1903 is mounted on the outer end of the adjusting rod 1902.

[0049] The opposite sides of the fixed clamping block 1904 and the movable clamping block 1901 are both in an inwardly concave V-shaped structure, and the adjustment rod 1902 is threadedly connected to the limiting cylinder 12 through a thread.

[0050] In this embodiment, when in use, one end of the heterotopic bone is inserted into the limiting cylinder 12, so that the one end of the heterotopic bone squeezes the airbag sleeve 20. Due to the irregular shape of the end structure of the heterotopic bone, the inert gas inside the airbag sleeve 20 is fully distributed to ensure that the inner side of the airbag sleeve 20 is in close contact with the surface of the heterotopic bone. Then, the butterfly block 1903 is screwed to make the adjustment rod 1902 drive the movable clamping block 1901 close to the fixed clamping block 1904, thereby achieving the left and right clamping and fixing effect of one end of the heterotopic bone to ensure that the heterotopic bone is in a stable state during rotation. During the steam sterilization process, the exhaust hood 1403 sprays upward, and the limiting cylinder 12 is made of copper, which can absorb heat and cause the inert gas in the airbag sleeve 20 to expand when heated, so as to further promote the contact tightness between the airbag sleeve 20 and the ectopic bone. At the same time, the heat absorption effect of the inert gas is utilized to facilitate the heating of the clamping end of the ectopic bone, thereby ensuring the sterilization effect of the clamping end.

[0051] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
