[0015] The embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0016] Embodiment 1

[0017] like Figure 1 and Figure 2 As shown, this embodiment proposes an efficient and stable ultrasonic loop welding device for absorbable sutures, which integrates key components such as a loop ejector 1, a rotating handle 2, a loop base 3, an adjustable mold groove 4, a movable ejector 5, a displacement module 6, an ejector cylinder 7, and a mold base 8, which work together to achieve precise welding of sutures. The rotating handle 2, the loop ejector 1, the ejector cylinder 7, and the movable ejector 5 are all arranged on the mold base 8. The suture is cleverly placed in the adjustable mold groove 4. The suture passes through the adjustable mold groove 4 and rests on the loop ejector 1. The movable ejector 5 extends out under the action of the ejector cylinder 7 and cooperates with the loop ejector 1 to clamp the suture. The user gently operates the rotating handle to drive the loop ejector 1 to work accurately, so that the suture quickly forms a ring knot.

[0018] The device also has Figure 1 and Figure 2The ultrasonic welding machine, the fusion joint installation fixture and the linear guide lifting motion assembly not shown in the figure, the fusion joint installation fixture is installed on the frame through the linear guide lifting motion assembly, the linear guide lifting motion assembly is used to adjust the position of the fusion joint installation fixture in the vertical direction, and the fusion joint of the ultrasonic welding machine is installed in the fusion joint installation fixture. Specifically, the linear guide lifting motion assembly can realize the lifting motion control through the slider, servo motor and screw rod arranged on the frame. The ejector cylinder and the ultrasonic welding machine are respectively provided with a foot switch for controlling the on-off of the air circuit or the opening or closing of the welding work.

[0019] Before the device of the utility model works, the operator can select a mold of appropriate specifications for installation according to the specifications of the line to be looped, so as to ensure the matching degree between the mold and the suture line. Then, the suture line is laid flat in the adjustable mold groove to ensure the stability of the suture line during the welding process.

[0020] The operator controls the action of the ejector cylinder through the foot switch, so that the movable ejector extends and cooperates with the ring ejector to clamp the suture. At this time, the operator turns the rotating handle, and the flexible operation of the rotating handle will drive the ring ejector to work accurately, so that the suture quickly forms a ring knot.

[0021] After the loop is completed, step on the foot switch of the ultrasonic welding machine, the welding head will drop and start welding. The ultrasonic energy emitted by the ultrasonic equipment will accurately act on the loop knot to achieve the welding of the suture line. During the welding process, the position of the welding head in the welding method changes as follows Figure 3 As shown, during the looping process, the ejector cylinder 7 provides a stable clamping force to ensure that the suture remains stable during the welding process, and the looping ejector 1 completes the looping action to form a firm ring knot. After completing a loop welding, the movable ejector 5 is retracted under the drive of the ejector cylinder 7.
