Description

Technical Field

[0001] The present application relates to the technical field of medical suture processing, and in particular to a spindle for braiding medical suture. Background Art

[0002] The braiding machine is one of the main equipment required for the processing of medical sutures. The braiding machine includes a braiding unit and a wire-taking unit. The braiding unit includes a spindle, a track plate and a transmission assembly that drives the spindle to move on the track plate. The wire used to support the suture is wound on the spindle. The middle part of the track plate is provided with a winding rod. When the spindle is driven to move by the transmission assembly, the wire wound on the spindle begins to unwind and is wound on the winding rod. Different wires are woven together according to the changes in the position of each spindle, and the braided suture is then wound up by the wire-taking unit.

[0003] In the related art, the spindle is generally composed of a spindle frame and an axle rod. A bobbin is provided on the outer shell of the axle rod. The bobbin is used to wind the wire required for braiding the suture thread. The axle rod and the bobbin are detachably connected to the spindle frame so that when the spindle frame moves on the track plate with the transmission assembly, the axle rod and the bobbin can move accordingly.

[0004] The problem with the related technology is that during the suture thread weaving process, when the wire wrapped on the surface of the bobbin is about to be consumed, the bobbin needs to be replaced in time. However, it is inconvenient to remove the bobbin from the spindle frame, which affects work efficiency. Utility Model Content

[0005] In order to facilitate the disassembly and assembly of the thread barrel, the present application provides a spindle for braiding medical suture thread.

[0006] The medical suture weaving spindle provided in the present application adopts the following technical solution:

[0007] A spindle for braiding medical sutures comprises a spindle foot, wherein the spindle foot is provided with an axial hole, an axial rod is connected in the axial hole, a bobbin is sleeved on the outer side of the axial rod, a spindle rod is arranged on the spindle foot, the spindle rod extends upward in a direction parallel to the bobbin, a spindle frame is sleeved on the end of the spindle rod away from the spindle foot, a clamping and fixing mechanism is arranged on the side of the spindle frame facing the bobbin, a limited shaft seat is arranged at the end of the shaft rod away from the spindle foot, the limited shaft seat is cooperated with the clamping and fixing mechanism to fix the shaft rod to the bobbin, a wire passing assembly is also arranged on the spindle foot and the spindle frame, and a wire harness wound on the bobbin extends upward through the wire passing assembly.

[0008] By adopting the above technical solution, the bobbin is fixed on the shaft rod via the limiting shaft seat, and the clamping and fixing mechanism arranged on the spindle frame can further fix the limiting shaft seat on the spindle frame to ensure the stability of the bobbin and the shaft rod during the weaving process.

[0010] By adopting the above technical solution, when the clamping plate is rotated, the limit shaft seat is inserted into the limit hole, and the clamping plate and the limit shaft seat are clamped together to achieve fixation. When the clamping plate is rotated in the direction away from the shaft rod, the clamping plate is released and the limit shaft seat is separated from the clamping plate. Then, by removing the limit shaft seat from the shaft rod, the bobbin can be removed from the shaft rod to facilitate the disassembly and assembly of the bobbin.

[0011] Optionally, a clamping portion is provided in the middle part of the limiting shaft seat, and the diameter of the clamping portion is smaller than the diameter of the limiting shaft seat. The clamping portion is accommodated in a through groove, and a first groove body and a second groove body connected to each other are provided on the clamping plate. The diameter of the first groove body is larger than the diameter of the clamping portion and smaller than the diameter of the limiting hole, and the diameter of the second groove body is larger than the diameter of the limiting hole.

[0012] By adopting the above technical solution, when the first groove body corresponds to the limiting hole, the clamping plate is clamped with the limiting shaft seat. When the sliding clamping plate makes the second groove body correspond to the limiting hole, the fixing effect of the clamping plate and the limiting shaft seat can be released, and the operation is simple and convenient.

[0014] By adopting the above technical solution, when the first elastic member is in a naturally extended state, the first groove body corresponds to the limiting hole. At this time, the limiting shaft seat is clamped with the clamping plate. When the staff pushes the clamping plate to slide, the first elastic member is compressed, and the second groove body corresponds to the limiting hole. At this time, the clamping plate can be separated from the limiting shaft seat by rotating it.

[0018] By adopting the above technical solution, the spring reset mechanism, the lever and the lower wire mouth are arranged in coordination, the wire led out from the middle wire mouth first passes through the lower wire mouth, and then passes through the upper wire mouth to supply the wire to the outside. The setting of the spring reset mechanism can adapt to the changes in wire tension during the weaving process, thereby playing a role in wire breakage protection.

[0020] By adopting the above technical solution, when the wire tension is too tight, it can drive the lever to move, and then drive the rotating seat to rotate, so that the movable end of the rotating seat rotates toward the wire to adapt to the tension change. At this time, the second elastic member is deformed. When the wire tension is over-sent, the second elastic member restores the deformation, and the movable end of the rotating seat rotates away from the wire to adapt to the tension change, so that the wire tension is well controlled.

[0021] Optionally, a sliding ring is provided on the sliding sleeve on the surface of the spindle rod, and the shift rod is fixedly connected to the slip ring.

[0022] By adopting the above technical solution, the setting of the slip ring is used to limit the moving direction of the lever and the lower wire passing nozzle, thereby improving the stability during the adjustment process.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] The present application embodiment discloses a spindle for braiding medical sutures. Figure 1 A spindle for braiding medical sutures includes a spindle foot 1, a spindle rod 4 and a spindle frame 5 which are sequentially distributed from bottom to top, wherein the spindle foot 1 is fixed on a track plate of a braiding machine, the spindle rod 4 is mounted on the spindle foot 1 and extends vertically upward, and the spindle frame 5 is mounted on one end of the spindle rod 4 away from the spindle foot 1. The spindle frame 5 can specifically adopt a structure in which the main body is a sleeve, which is sleeved on the outside of the spindle rod 4 to achieve connection. In order to improve the overall structural strength of the spindle, two spindle rods 4 can be provided, and the spindle frame 5 is correspondingly provided with two sleeves, and the two spindle rods 4 are respectively inserted into the two sleeves.

[0032] Reference Figure 2 An axial hole is opened in the spindle foot 1, and a shaft rod 2 is inserted in the axial hole. A bobbin 3 is arranged on the outer shell of the shaft rod 2. The bobbin 3 is used for winding the wire required for braiding the suture thread. A fixing structure is arranged on the shaft rod 2, which is used to fix the bobbin 3 on the shaft rod 2 to prevent the bobbin 3 from moving relative to the shaft rod 2.

[0033] Specifically, the solid structure can be composed of a limiting shaft seat 7 and a chuck respectively arranged at both ends of the bobbin 3, a protrusion is formed on the chuck, and a matching groove is correspondingly formed on the side of the bobbin 3 facing the chuck. Preferably, the chuck is arranged at the end of the bobbin 3 close to the spindle foot 1, that is, the bobbin 3 is placed above the chuck, so that the protrusion cooperates with the groove to limit the bobbin 3. The limiting shaft seat 7 is correspondingly arranged at the end of the bobbin 3 away from the chuck, and the shaft rod 2 is a hollow rod-shaped structure, and an internal thread is provided on the inner wall of the end close to the limiting shaft seat 7. The limiting shaft seat 7 has a threaded tube portion extending downward, and the limiting shaft seat 7 can be threadedly connected to the shaft rod 2 through the threaded tube portion. It can be understood that a pressure plate can be formed on the limiting shaft seat 7. When the limiting shaft seat 7 is threadedly connected to the shaft rod 2, the pressure plate abuts against one end face of the bobbin 3 to further limit the position of the bobbin 3.

[0034] Reference Figure 2 and Figure 3 A clamping and fixing mechanism 6 is provided on the spindle frame 5 for fixing the limiting shaft seat 7. The clamping and fixing mechanism 6 includes a clamping plate 61, which is rotatably mounted on the spindle frame 5 via a rotating shaft, and the rotation axis of the clamping plate 61 is perpendicular to the straight line where the shaft rod 2 is located. A limiting hole is provided on the clamping plate 61 that passes through the upper and lower parts. When the clamping plate 61 rotates toward the shaft rod 2, the limiting shaft seat 7 can be inserted into the limiting hole; when the clamping plate 61 rotates away from the shaft rod 2, the limiting shaft seat 7 can be separated from the limiting hole.

[0035] Furthermore, a through slot is provided in the middle of the clamping plate 61 and passes through one side thereof. The plane where the through slot is located is parallel to the plane where the clamping plate 61 is located. A clamping plate 62 is slidably connected in the through slot. One end of the clamping plate 62 passes through the through slot and extends to the outside of the clamping plate 61 to form a force-bearing end for the staff to drive. The clamping plate 62 is provided with a first slot body 621 and a second slot body 622 that are interconnected. The size of the first slot body 621 is slightly smaller than the size of the limiting hole, and the size of the second slot body 622 is larger than the size of the limiting hole.

[0036] Furthermore, a clamping portion 71 is formed in the middle of the limiting shaft seat 7. When the limiting shaft seat 7 is inserted into the limiting hole, the clamping portion 71 is correspondingly placed in the through groove. At this time, the first groove body 621 corresponds to the position of the limiting hole, so that the limiting shaft seat 7 is clamped and fixed by the clamping plate 62. When the staff pushes the clamping plate 62 into the through groove through the force-bearing end of the clamping plate 62, the second groove body 622 moves to the position corresponding to the limiting hole. At this time, the fixing effect of the clamping plate 62 and the limiting shaft seat 7 is released, and the clamping plate 61 can be rotated to separate the clamping plate 61 from the limiting shaft seat 7.

[0037] Furthermore, after the clamping plate 61 is separated from the limiting shaft seat 7, the limiting shaft seat 7 is rotated to remove it from the shaft rod 2, and then an upward external force is applied to the bobbin 3 to remove the bobbin 3.

[0038] It is understandable that, in order for the force-bearing end of the card plate 62 to be able to extend out of the through slot and return to its original position after the staff member contacts the external force on the card plate 62, a first elastic member 63 is fixedly installed in the through slot, and the card plate 62 is connected to the first elastic member 63. When the first elastic member 63 is in a naturally extended state, the force-bearing end of the card plate 62 is located outside the clamping plate 61, and when the staff member applies an external force to the card plate 62 to push the force-bearing end into the through slot, the first elastic member 63 is deformed. After the external force is removed, the first elastic member 63 recovers the deformation and pushes the card plate 62 out of the through slot, so that its force-bearing end can return to its original position.

[0039] Reference Figure 4 A wire passing assembly 8 is also provided on the spindle foot 1 and the spindle frame 5. The wire passing assembly 8 includes an upper wire passing nozzle 81, a middle wire passing nozzle 82 and a lower wire passing nozzle 83 which are sequentially distributed from top to bottom. The wire material drawn from the wire drum 3 first passes through the middle wire passing nozzle 82, then passes through the lower wire passing nozzle 83, and finally passes through the upper wire passing nozzle 81 for wire feeding. Preferably, the upper wire passing nozzle 81 and the middle wire passing nozzle 82 are respectively arranged at the upper end and the lower end of the spindle frame 5, and the lower wire passing nozzle 83 is arranged on the spindle foot 1.

[0040] Specifically, mounting portions 51 are formed at the upper and lower ends of the spindle frame 5, respectively. The mounting portions 51 are provided with clamping holes, and the upper thread passing nozzle 81 and the middle thread passing nozzle 82 are fixed in the clamping holes by clamping.

[0041] Reference Figure 2 and Figure 4 A spring return mechanism 9 is arranged on the spindle foot 1, and the spring return mechanism 9 includes a rotating seat 91 rotatably mounted on the spindle foot 1, and the rotating seat 91 has a rotating end 911 and a movable end 912, wherein the rotating end 911 is rotatably connected to the rotating seat 91 through a rotating shaft, and a lever 10 is connected to the movable end 912 of the rotating seat 91, and the lever 10 extends vertically upward, and the above-mentioned lower thread nozzle 83 is formed at the end of the lever 10 away from the spindle foot 1.

[0042] Furthermore, a mounting hole is opened in the spindle foot 1, and the spring return mechanism 9 also includes a second elastic member 93 installed in the mounting hole and distributed vertically. The bottom end of the second elastic member 93 is fixed in the mounting hole, and a driving rod 92 is installed on the top. A slide groove 94 is opened on the surface of the spindle foot 1, and the driving rod 92 extends into the slide groove 94.

[0043] Furthermore, a movable groove 913 is partially opened between the rotating end 911 and the movable end 912 of the rotating seat 91 . The movable groove 913 is matched with the sliding groove 94 , and the driving rod 92 further extends into the movable groove 913 .

[0044] With the above structure, when the spindle is feeding the wire outward, the second elastic member 93 is stretched and contracted to adapt to the change of the wire tension, so as to prevent the wire from being continuously fed and finally disconnected under the condition of excessive tension. Figure 4 Initially, the driving rod 92 is located at the bottom of the slide groove 94. At this time, the distance between the movable end 912 of the rotating seat 91 and the middle wire passing nozzle 82 is the largest. When the wire tension is too tight, the wire will pull the rotating seat 91 through the movable end 912 to make the rotating seat 91 rotate, and its movable end 912 moves in the direction close to the middle wire passing nozzle 82 to adapt to the change of wire tension. During the rotation of the rotating seat 91, the side wall of the movable groove 913 can be used to push the driving rod 92 to slide upward in the slide groove 94, thereby extending the second elastic member 93; when the wire tension is too loose, the second elastic member 93 will restore its deformation, and the driving rod 92 will move downward, thereby driving the rotating seat 91 to rotate, so that the movable end 912 of the rotating seat 91 moves in the direction away from the middle wire passing nozzle 82 to adapt to the change of wire tension.

[0045] 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.
