[0034] Combine the following Figure 1-Figure 6 , describing a sterilization device for suture production according to an embodiment of the present invention.

[0035] The housing 100 may be in a box shape, and a sterilization chamber is arranged in the housing 100. A sterilization lamp 103 is arranged at the bottom of the sterilization chamber, and the light of the sterilization lamp 103 radiates from bottom to top into the sterilization chamber. The torsion mechanism 200, the suture clamp 202, the rotating block 210, the spring 230 and the regularization assembly 220 are all located in the sterilization chamber.

[0036] The suture clamp 202 includes two clamping members, which clamp two ends of the suture 203 respectively, so that the suture 203 remains straight. The clamping member is detachably connected to the housing 100 so that the suture 203 can be installed on the clamping member.

[0037] There are four rotating blocks 210 , which are rotatably connected to the housing 100 . The rotating blocks 210 are circumferentially provided with mating teeth 211 . Every two rotating blocks 210 form a group and are coaxially arranged, and the mating teeth 211 of the two groups of rotating blocks 210 mesh with each other.

[0038] The torsion drive assembly is used to drive one of the rotating blocks 210 to rotate in the opposite direction. In one embodiment, the torsion drive assembly includes two torsion motors 204 , which are fixed on the housing 100 and are in driving connection with the rotating blocks 210 .

[0039] There are two springs 230 ; the axial end of each spring 230 is axially movably connected to a set of rotating blocks 210 ; wherein the suture clamp 202 is located between the two springs 230 .

[0040] The structuring component 220 includes a connecting unit and at least two structuring heads 223; the connecting unit is movably connected to the housing 100 and can move axially and radially along the spring 230; every two structuring heads 223 are located on both sides of the axial direction of the suture 203 and are respectively slidably connected to a spring 230; a suture mating groove 2231 is provided on one side of the structuring head 223, and a spring mating groove 2232 connected to the suture mating groove 2231 is provided on the other side of the structuring head 223.

[0041] Working process of the sterilization device for suture production:

[0042] The suture clamp 202 is used to clamp the two ends of the suture 203 so that the suture 203 is straightened and located between the two regular heads 223; the torsion drive assembly drives one group of rotating blocks 210 to rotate in the opposite direction, and the other group of rotating blocks 210 is driven by the matching teeth 211 to rotate in the same way, and the two adjacent rotating blocks 210 turn in opposite directions. The same group of rotating blocks 210 drives the spring 230 to twist, and the twisted spring 230 can be shortened and in a compressed state, at which time the radial size of the spring 230 becomes larger; the twisted spring 230 can also be extended and in a stretched state, at which time the radial size of the spring 230 becomes smaller. The shortening or elongation of the spring 230 is related to the rotation direction of the rotating block 210 and the rotation direction of the spring 230. When the diameter of the suture 203 is smaller than the spacing between the two sizing heads 223, the suture 203 is first placed on the suture clamp 202, and the rotating block 210 is used to compress the two springs 230. The sizing heads 223 that cooperate with the springs 230 move closer to the suture 203. The sizing heads 223 drive the connecting unit to move axially and radially along the springs 230 relative to the housing 100. The two sizing heads 223 clamp the suture 203. Since the suture matching groove 2231 is connected to the spring matching groove 2232, the spring 230 is in contact with the suture 203 at this time, and the two springs 230 are twisted in the opposite direction so that the suture 203 is forced to spread out into the shape of multiple strands of sub-wires. When the diameter of the suture 203 is greater than the spacing between the two regularization heads 223, the rotating block 210 is used to drive the two springs 230 to stretch, and the regularization head 223 matched with the spring 230 is away from the suture 203. The regularization head 223 drives the connection unit to move axially and radially relative to the housing 100 along the spring 230, and the suture 203 is placed between the two regularization heads 223. Then, the spring 230 is naturally loosened by the torsion drive assembly. At this time, the two regularization heads 223 clamp the suture 203, and the two springs 230 are reversely twisted so that the suture 203 is forced to spread into the shape of multiple strands. The light emitted by the sterilization lamp 103 shines on the strands to sterilize the outside and inside of the suture 203, and the sterilization effect is good.

[0043] In one embodiment, the connecting unit includes two mounting blocks 224 and at least two regularizing rods 222; the housing 100 is provided with a sliding groove 104, the mounting block 224 cooperates with the sliding groove 104 and can move radially along the spring 230; the mounting block 224 is provided with a movable groove 221 extending axially along the spring 230; one end of the regularizing rod 222 is slidably arranged in the movable groove 221, and the other end of the regularizing rod 222 is connected to the regularizing head 223.

[0044] The mounting block 224 can be in the shape of a long strip, and the long side of the mounting block 224 is parallel to the axial direction of the spring 230. When the mounting block 224 is matched with the sliding groove 104, the two ends of the mounting block 224 in the length direction abut against the groove wall of the sliding groove 104. The width direction of the mounting block 224 is the radial direction of the spring 230, and there is a gap between the two ends of the mounting block 224 in the width direction and the groove wall of the sliding groove 104, so that when the radial dimension of the spring 230 changes, the regularization head 223 can drive the mounting block 224 to slide in the sliding groove 104 through the regularization rod 222.

[0045] The long side of the movable groove 221 is parallel to the axial direction of the spring 230. When the regularizing rod 222 is matched with the movable groove 221, the regularizing rod 222 is restricted from moving radially along the spring 230 in the movable groove 221. When the axial dimension of the spring 230 changes, the regularizing head 223 can drive the regularizing rod 222 to slide along the movable groove 221.

[0046] The number of the regularizing rods 222 is the same as the number of the regularizing heads 223. The number of the regularizing heads 223 is an even number, for example, 16. Each mounting block 224 can be provided with 8 regularizing rods 222, and all regularizing heads 223 corresponding to the same mounting block 224 have the same orientation. There are two mounting blocks 224, and the long sides are parallel to the axial direction of the spring 230.

[0047] In one embodiment, a spring stopper 2233 is provided at a portion of the tidying head 223 close to the spring matching groove 2232 .

[0048] The tidying head 223 may be in the shape of a cuboid. After the tidying head 223 is connected to the tidying rod 222, the long side of the tidying head 223 is parallel to the length direction of the tidying rod 222. The extension direction of the spring matching groove 2232 is arranged at an angle with the long side of the tidying head 223, and the size of the angle is related to the helical angle of the spring 230. The suture matching groove 2231 runs through the tidying head 223, the axis of the suture matching groove 2231 is parallel to the axial direction of the spring 230, and the suture matching groove 2231 passes through the center of the tidying head 223.

[0049] When the spring 230 is twisted, some parts of the spring 230 slide in the spring matching groove 2232. The spring limit block 2233 is located at the end of the regular head 223 away from the suture matching groove 2231. The spring limit block 2233 spans the notch of the suture matching groove 2231 to prevent the spring 230 from detaching from the spring matching groove 2232.

[0050] In one embodiment, one end of the sizing head 223 away from the sizing rod 222 has a chamfer, and the chamfer slope faces the suture 203. When the suture 203 is installed, it is inserted between the two sizing heads 223 from bottom to top, and the sizing head 223 is chamfered to facilitate the suture 203 to be inserted between the two sizing heads 223. The chamfer can be an arc angle.

[0051] In one embodiment, both ends of the spring 230 are provided with a spring connector 231 extending axially along the spring 230; the rotating block 210 is provided with a first limiting groove 213 cooperating with the spring connector 231, and the spring connector 231 can move radially and axially along the first limiting groove 213.

[0052] The spring connector 231 may be a cylinder and extend along the axial direction of the spring 230. The first limiting groove 213 may be a rectangular groove. When the spring connector 231 is inserted into the first limiting groove 213, the rotation of the rotating block 210 will drive the spring connector 231 to rotate together, thereby driving the spring 230 to twist. In the radial direction, the spring connector 231 may be located in the middle of the first limiting groove 213. When the radial dimension of the spring 230 changes, the spring connector 231 may slide radially along the first limiting groove 213. In the axial direction, there is a gap between the end of the spring connector 231 and the bottom of the first limiting groove 213. When the axial dimension of the spring 230 changes, the spring connector 231 may slide axially along the first limiting groove 213.

[0053] It should be noted that when the spring 230 is shortened, the shortening amount of the spring 230 is limited, and the spring connector 231 will not be separated from the first limiting groove 213 .

[0054] In one embodiment, the torsion mechanism 200 further includes a limiting tube 212; the limiting tube 212 is sleeved on the outside of the rotating block 210, and the limiting tube 212 is used to limit the spring connector 231 from radially disengaging from the first limiting groove 213. When the radial dimension of the spring 230 increases, the spring connector 231 may radially disengage from the first limiting groove 213, so the limiting tube 212 is sleeved on the outside of the rotating block 210, and the length of the limiting tube 212 may be equal to the length of the first limiting groove 213 along the axial direction of the spring 230.

[0055] In one embodiment, the housing 100 is provided with a mounting plate 201, and the mounting plate 201 is provided with a mounting hole matched with the rotating block 210; a limit block is provided on the rotating block 210, and the outer diameter of the limit block and the outer diameter of the matching tooth 211 are both larger than the outer diameter of the rotating block 210, and a second limit groove 214 for clamping the mounting plate 201 is formed between the limit block and the matching tooth 211. The mounting plate 201 supports and positions the rotating block 210, and the number of the mounting plates 201 can be two and they are respectively located at both ends of the spring 230. The second limit groove 214 can limit the movement of the rotating block 210.

[0056] In one embodiment, the mounting plate 201 divides the sterilization chamber into a first chamber and a second chamber; the sterilization lamp 103 is located in the first chamber; the torsion drive assembly is located in the second chamber; and the housing 100 is provided with a heat dissipation hole 102 connected to the second chamber.

[0057] There are two second chambers, which are located on both sides of the first chamber. The torsion drive assembly includes two torsion motors 204, which are used to drive two coaxial rotating blocks 210. The torsion motors 204 can be fixed to the housing 100 through a bracket (not shown in the figure), and the rotating shaft of the torsion motor 204 passes through the mounting plate 201 and is connected to the rotating block 210. The torsion motor 204 may generate heat during operation, and the heat dissipation hole 102 can facilitate the heat of the torsion motor 204 to be discharged from the second chamber.

[0058] In one embodiment, the sterilization chamber has a discharge port for placing the suture 203; the mounting plate 201 is provided with a placement groove 2011 that cooperates with the suture clamp 202, the placement groove 2011 is L-shaped and the opening of the placement groove 2011 is connected to the discharge port, and the end of the placement groove 2011 is located between the two springs 230.

[0059] The housing 100 is provided with a door body 101 for sealing the discharge port. One end of the door body 101 is rotatably connected to the housing 100, and the other end of the door body 101 is a free end and is detachably connected to the housing 100. The connection method can be but is not limited to a snap connection method.

[0060] The suture clamp 202 includes a clamping member, and the placement groove 2011 cooperates with the clamping member. The clamping member may be L-shaped, and one end of the clamping member cooperates with the placement groove 2011, and the other end of the clamping member is used to clamp the suture 203. The clamping member can be slid along the placement groove 2011 to facilitate moving the suture 203 between the two springs 230 or taking it out from between the two springs 230, and the operation is simple and convenient.

[0061] In one embodiment, the spring 230 includes a telescopic portion and two mounting portions; the two mounting portions are located at two ends of the telescopic portion; and the cross-sectional area of ​​the mounting portion is greater than the cross-sectional area of ​​the telescopic portion.

[0062] The cross-sectional area of ​​the mounting portion refers to the cross-sectional area of ​​the spring wire corresponding to the mounting portion, and the cross-sectional area of ​​the telescopic portion refers to the cross-sectional area of ​​the spring wire corresponding to the telescopic portion. The cross-sectional area of ​​the mounting portion is larger than the cross-sectional area of ​​the telescopic portion, so that the spring wires at both ends of the spring 230 are thicker, and the spring wires in the middle section of the spring 230 are thinner. When the spring 230 is twisted, the two ends of the spring 230 are relatively stable and the deformation generated is small, and the deformation generated in the middle section of the spring 230 is large. The synchronization of the deformation at both ends of the spring 230 can also be ensured, so that the deformation of the middle section of the spring 230 is relatively uniform, so that the degree of expansion of each axial part of the suture 203 is relatively consistent, which is convenient for uniform ultraviolet irradiation.

[0063] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-described embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present application.
