Description

Technical Field

[0001] The present invention relates to the field of suture crimping methods, and more particularly to a suture crimping method and a system thereof. Background Art

[0002] Surgical sutures are commonly used medical consumables, widely used in wound suturing, tissue apposition, lumen ligation and anastomosis, joint and implant fixation, wound and ligament repair and other processes. Sutures are generally used in conjunction with suture needles, and suture needles mainly play a traction role. In any operation, the needle and thread connection strength of the suture needle and suture is extremely important. If the needle and thread connection strength is poor, it is easy to cause the needle and thread to fall off during the suturing process, which may result in the removal of the sutures and re-suturing, or even life-threatening. In either case, it will cause great damage to the sutured part and cause secondary damage to the injured. Therefore, it is crucial to control the needle and thread connection strength.

[0003] Most of the crimping equipment used for medical suture needles and sutures in the medical industry is manually operated. It is necessary to pre-set the suture needle on one side of the equipment's crimping slot, hold it with your hand, and then insert the suture into the tail of the suture needle with the other hand. To ensure the crimping quality and loss rate, another person usually performs the crimping operation. The crimping operation requires crimping once when the suture is inserted, and then crimping once after rotating 30° and 60°, for a total of 3 operations. Traditional crimping equipment is inefficient and requires two people to operate. Because it is manual crimping, the crimping force of the three times is difficult to unify, and the needle tail is subjected to different degrees of force during crimping, and the appearance is prone to obvious defects such as obvious indentations, cracks, and crushing. In addition, the labor cost is high and the accuracy is difficult to control. Summary of the invention

[0004] To achieve the above-mentioned object, the present invention provides the following technical solutions: a suture crimping system, comprising a suture placement module, a first clamping portion that moves back and forth, a second clamping portion that moves back and forth, a suture needle placement module that moves back and forth, and a suture crimping module;

[0036] Wherein, the suture placement module 1 is used to store sutures 10;

[0037] The first clamping portion 3 moves on a fixed track, and is used to clamp and push the suture 10 output by the suture placement module 1, and solidify the front end of the suture 10;

[0038] The second clamping portion 4 moves on a fixed track to push the solidified suture 10 toward the needle placement module 6 and the suture crimping module 5 and cut the suture 10;

[0039] The suture needle placement module 6 is used to place the suture curved needle and drive the suture curved needle to move toward the suture crimping module 5 on a fixed track;

[0040] The suture crimping module 5 is located at the front end of the moving track of the first clamping part 3 and the second clamping part 4, and performs multi-angle crimping on the suture curved needle tail 7;

[0041] Furthermore, a traction module is provided on one side of the suture 10 placement module 1. The traction module is specifically a plurality of jaws for pulling the suture 10 to move. The suture 10 on the wire drum is pulled by the plurality of jaws. While the suture 10 is pulled, the portion that cooperates with the tail of the suture needle 7 is solidified. A suture needle placement module 1 is provided at the front end of the suture 10. The suture 10 is pulled by one of the jaws to insert the solidified portion at the front end into the tail of the suture needle 7. After being installed in place, the crimping module crimps the tail of the suture needle 7 at three angles.

[0042] The suture placement module 1 comprises a suture roller, on which a suture 10 is wound, and after being pulled by the pulling module, the front end of the suture 10 is inserted into the tail of the suture curved needle 7;

[0043] The suture needle placement module 6 is used to fix and transport the suture curved needle 7; when in use, the suture curved needle 7 is first placed in the positioning groove set on the suture needle placement module 6, and the suture needle placement module 6 moves to bring the suture curved needle 7 to the working position.

During the crimping process, the first crimping joints 81 on both sides of the suture curved needle 7 move toward each other to complete the crimping, and the movement directions of the two first crimping joints 81 are mutually horizontal.

[0047] like Figure 1-3 and Figure 5 As shown, a guide ring 2 is provided between the suture placement module 1 and the traction module, and the suture 10 on the suture placement module 1 passes through the guide ring 2 and is then installed in the traction module.

[0048] A trumpet-shaped guide hole 21 is provided in the guide ring 2, and a first rounded corner 22 and a second rounded corner 23 are provided at both ends of the guide hole 21. The first rounded corner 22 and the second rounded corner 23 can prevent the suture 10 from rubbing against it and causing failure.

[0049] The portion of the suture 10 inserted into the tail of the suture needle 7 is provided with a curing section, and the curing section can be heated; providing the curing section can facilitate the insertion of the suture 10 into the tail of the suture needle 7, while ensuring its integrity to avoid burrs during crimping.

[0050] Furthermore, the first clamping part 3 includes a second module bracket 31, and the second module bracket 31 is provided with a rear clamping claw 32 for clamping the suture 10.

The front end of the adjustment column 941 is installed in the space cam 952, so that the crimping slider 94 can be driven by the rotation of the crimping adjustment disk 95 to cooperate with the space cam 952.

[0057] Based on the above, when the adjustment column 941 is located within the cam high point 953, its crimping slider 94 moves toward the center, so that when the crimping adjustment disk 95 rotates one circle, the crimping of three groups of crimping heads can be completed. The stability of the spatial cam can be used to simplify the structure and avoid excessive control and driving costs.

[0058] The crimping adjustment disk 95 can be driven by a rotating cylinder, a motor, a gear, a connecting rod, etc., and the driving power source can be set on the module mounting block 91.

[0059] Furthermore, an adjustment through hole 924 is provided on the bottom surface of the pressing block installation slot 922, and an adjustment column 941 is provided on the crimping slider 94. The adjustment column 941 is movably installed in the adjustment through hole 924. A crimping adjustment disk 95 is provided on the side of the pressing block installation slot 922. The crimping adjustment disk 95 is provided with a space cam 952. The space cam 952 is provided with two mutually symmetrical cam high points 953. The front end of the adjustment column 941 is installed in the space cam 952, so that the crimping slider 94 can be driven by the rotation of the crimping adjustment disk 95 to cooperate with the space cam 952.

[0060] Based on the above, when the adjustment column 941 is located within the cam high point 953, its crimping slider 94 moves toward the center, so that when the crimping adjustment disk 95 rotates one circle, the crimping of three groups of crimping heads can be completed. The stability of the spatial cam can be used to simplify the structure and avoid excessive control and driving costs.

[0061] Furthermore, the crimping adjustment disk 95 can be driven by a rotating cylinder, a motor, a gear, a connecting rod, etc., and the driving power source can be set on the module mounting block 91.

[0062] Furthermore, an inner fixing plate and an outer fixing plate are respectively provided at both ends of the crimping ring, and the inner fixing plate and the outer fixing plate are fixedly installed by bolts, so that the crimping adjustment plate and the crimping slider can be fixed.

[0064] Example 3

[0065] The suture crimping method comprises the following steps:

[0066] Step 1: Lead the suture 10 from the bottom of the suture placement module 1, pass through the guide ring 2, and then clamp and fix it through the first clamping part 3 and the second clamping part 4;

[0067] Step 2: When the second clamping part 4 clamps the suture 10, the front end is exposed to the solidified section;

[0068] Step 3: Place the suture curved needle 7 into the suture needle placement module 6, the suture needle placement module 6 transports the suture curved needle 7 to the crimping position, the first clamping part 3 releases the suture 10, the second clamping part 4 clamps the suture 10 and moves forward to insert the front end solidified part of the suture 10 into the mounting hole at the tail end of the suture curved needle 7, and at the same time drives the rolling release of the suture placement module 1;

[0069] Step 4: The sewing needle crimping module 5 moves downward to crimp the sewing needle three times, and after each crimping, it rotates 30-120 degrees and crimps again. After all three times are completed, the sewing needle crimping module 5 returns to its original position;

[0070] Step 5: The first clamping part 3 moves to clamp the position that needs to be cured next time for clamping and curing, and releases after curing is completed, and the second clamping part 4 moves backward to clamp the rear end position of the curing;

[0071] Step 6: The front end of the solidified section of the suture 10 is cut off by the thread cutter 42, and the suture needle placement module 6 returns to its original position, completing a crimping.
