[0034] The following is combined with Figure 1-5 This application is described in further detail.

[0035] The present application embodiment discloses a wire take-up device for a medical suture braiding machine. Figure 1A wire-receiving device of a medical suture braiding machine comprises a braiding machine frame 1 and a support rod 2 vertically mounted on the braiding machine frame 1, a wire-passing mechanism 3, a wiring mechanism 5 and a wire-receiving mechanism 4 are arranged on the support rod 2, a braiding unit (not shown in the drawings) for braiding the suture into shape is arranged on the braiding machine frame 1, after the braiding unit braids the suture into shape, the suture passes through the wire-passing mechanism 3 and the wiring mechanism 5 in sequence, and is finally wound up on the wire-receiving mechanism 4, wherein the wiring mechanism 5 is used to make the suture evenly distributed on the wire-receiving mechanism 4.

[0036] Reference Figure 1 The wire passing mechanism 3 is arranged above the braiding machine frame 1, and is used to guide the suture thread to the wiring mechanism 5. The wire passing mechanism 3 includes a wire passing wheel 31 and a wire passing plate 32, wherein the wire passing plate 32 is provided with a wire passing hole 33, the wire passing hole 33 and the wire passing wheel 31 are in the same vertical plane, and the wire passing wheel 31 is located above the wire passing plate 32. When the suture thread is led out from the braiding unit, it first passes through the wire passing hole 33, and then bypasses the wire passing wheel 31 to extend to the wiring mechanism 5.

[0037] A height adjustment block 7 is installed on the support rod 2, and an adjustment hole is provided on the height adjustment block 7, and an adjustment rod 8 is inserted in the adjustment hole. The adjustment rod 8 can slide up and down relative to the height adjustment block 7. A horizontal adjustment block 9 is installed at one end of the adjustment rod 8 facing the braiding machine frame 1, and the horizontal adjustment block 9 is also provided with an adjustment hole, so as to be able to adjust the height, i.e., the left and right position, of the wire passing mechanism 3. How to make the adjustment rod 8 / horizontal adjustment block 9 slide relative to the height adjustment block 7 / adjustment rod 8, and how to fix the position of the adjustment rod 8 and the horizontal adjustment block 9 after the adjustment is completed, this part belongs to conventional technology and is not limited here.

[0038] On the path where the suture line passes around the wire wheel 31 and extends to the wiring mechanism 5, a winding wheel group 10 is also provided. The winding wheel group 10 is composed of two winding wheel bodies 101, and wire grooves are provided on the two winding wheel bodies 101. A gear transmission assembly 11 is provided on the support rod 2 to drive the two winding wheel bodies 101 to rotate. The suture line passing through the wire passing mechanism 3 is wound between the two winding wheel bodies 101, and finally leads upward through one of the winding wheel bodies 101 to the wiring mechanism 5. The above-mentioned gear transmission assembly 11 is common knowledge and will not be described in detail. Of course, those skilled in the art can also use other components that can achieve the same effect, which is not limited here.

[0039] Reference Figure 1 and Figure 2The wiring mechanism 5 includes a linear moving component 51 and a wiring plate 52 installed on the driving end of the linear moving component 51. The wiring plate 52 is provided with a wiring hole 53. The suture thread drawn from the winding wheel group 10 passes through the wiring hole 53 and is finally wound on the wire-receiving mechanism 4. When the linear moving component 51 drives the wiring plate 52 to move, the winding position of the suture thread on the wire-receiving mechanism 4 can be adjusted. The linear moving component 51 can be a screw transmission structure, which is composed of a screw, a slide bar and a slider. The screw and the slide bar are parallel to each other. The slider is provided with a screw nut hole and a slide hole to match the screw and the slide bar. A forward and reverse motor is installed at one end of the screw. The forward and reverse motor drives the screw to rotate, so that the slider moves linearly. The wiring plate 52 is fixed on the slider. The moving direction of the slider is controlled by controlling the rotation direction of the forward and reverse motor.

[0040] Reference Figure 1 The wire-receiving mechanism 4 is arranged at the top of the support rod 2. The wire-receiving mechanism 4 includes a rotating shaft 41 rotatably mounted on the support rod 2. The straight line where the rotating shaft 41 is located is perpendicular to the support rod 2. A wire-receiving drum 42 is sleeved on the rotating shaft 41. The wire-receiving drum 42 is used to wind the suture. It can be understood that in order for the wiring mechanism 5 to evenly wind the suture on the wire-receiving drum 42, the moving direction of the wiring board 52 should be parallel to the axis of the wire-receiving drum 42. The wire-receiving mechanism 4 also includes a second motor 43 connected to the rotating shaft 41. The second motor 43 is used to drive the rotating shaft 41 and the wire-receiving drum 42 to rotate. During the rotation of the wire-receiving drum 42, the suture is wound on the wire-receiving drum 42. Preferably, the moving path of the wiring board 52 is slightly larger than the length of the wire-receiving drum 42. When the linear moving component 51 drives the wiring board 52 to move, it moves from one end of the wire-receiving drum 42 to the other end. Then, the linear moving component 51 drives the wiring board 52 to move in the opposite direction, so that the suture is evenly wound on the surface of the wire-receiving drum 42.

[0041] It should be noted that two mutually cooperating limit members 44 should be sleeved on the rotating shaft 41, wherein one limit member 44 is fixedly connected to the rotating shaft 41, and the other limit member 44 is detachably connected to the rotating shaft 41, and the limit member 44 detachably connected to the rotating shaft 41 is relatively arranged at the end of the rotating shaft 41 away from the support rod 2, and a space for fixing the position of the take-up reel 42 is formed between the two limit members 44.

[0042] Reference Figure 1 and 3The support rod 2 is specifically composed of a first part 21 and a second part 22, wherein one end of the first part 21 is fixed on the braiding machine frame 1, and the other end extends vertically upward, and the second part 22 is rotatably mounted on the upper end of the first part 21, and a rotation drive assembly 23 is provided at the rotation connection between the first part 21 and the second part 22, and the rotation drive assembly 23 is configured to drive the second part 22 to rotate a certain angle relative to the first part 21. Preferably, the maximum rotation angle of the second part 22 is 90°, that is, it has two extreme positions within its rotation range, one of which is parallel to the first part 21, and the other is perpendicular to the first part 21. The rotation drive assembly 23 is common knowledge and will not be described in detail here.

[0043] Furthermore, the wire passing mechanism 3 is arranged on the first part 21, and the wire taking-up mechanism 4 and the wiring mechanism 5 are arranged on the second part 22, that is, when the rotary drive assembly 23 drives the second part 22 to rotate, the wire taking-up mechanism 4 and the wiring mechanism 5 can rotate accordingly. It can be understood that when the second part 22 is in the first extreme position, the height of the wire taking-up mechanism 4 is the highest, and when the second part 22 is in the second extreme position, the height of the wire taking-up mechanism 4 is the lowest, so that the staff can remove the wire taking-up reel 42 full of suture thread and install a new wire taking-up reel 42 conveniently.

[0044] Reference Figure 1 , Figure 4 and Figure 5 A clamping assembly 6 is provided on the wiring mechanism 5, and the clamping assembly 6 is specifically arranged on the wiring plate 52 so as to be able to change with the change of the position of the suture thread passing through the wiring hole 53. When removing the take-up drum 42, the second part 22 can be driven to rotate to the second extreme position by the rotating drive assembly 23, and then the clamping assembly 6 clamps and fixes the suture thread, and then the staff cuts one end of the suture thread close to the take-up drum 42, and then the take-up drum 42 can be removed; after replacing the new take-up drum 42, the end of the suture thread is grasped again, so that the clamping assembly 6 prevents the suture thread from loosening, and the staff re-fixes the end of the suture thread on the take-up drum 42, and then the rotating drive assembly 23 drives the second part 22 to rotate to the first extreme position, and then the take-up work can be started.

[0045] Specifically, the clamping mechanism includes two movable rods 61 rotatably mounted on the wiring plate 52. The two movable rods 61 are symmetrically distributed along the central axis of the wiring hole 53. A first clamping head 62 and a second clamping head 63 are respectively arranged at one end of the two movable rods 61 close to the wiring hole 53. A sector-shaped toothed ring 611 meshing with each other is formed in the middle of the two movable rods 61. One of the movable rods 61 is connected to a first motor 64. The first motor 64 drives one of the movable rods 61 to rotate. The sector-shaped toothed ring 611 formed on the movable rod 61 drives the other sector-shaped toothed ring 611 to rotate, thereby rotating the other movable rod 61. According to the different rotation directions of the first motor 64, the first clamping head 62 and the second clamping head 63 are moved closer to or farther from each other. When the first clamping head 62 and the second clamping head 63 are in close contact with each other, the suture thread is clamped and fixed.

[0046] The first clamping head 62 and the second clamping head 63 can specifically adopt the following structure: a clamping groove 621 is provided on the side of the first clamping head 62 facing the second clamping head 63. When the first clamping head 62 and the second clamping head 63 are close to each other, the second clamping head 63 can be inserted into the clamping groove 621. During this process, the suture thread is clamped into the clamping groove 621 by the second clamping head 63. The use of this structure can further improve the fixing effect of the suture thread.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
