Description

Jig for threading fiber wool

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a fiber wool penetrating jig.

Background

Coil embolization is the placement of metallic coils one by one to a target lesion in a blood vessel. By placing the spring ring, blood flow is blocked, blood gradually coagulates, and thrombus is formed, so that the purpose of blocking or embolizing a lesion part is achieved. Studies have shown that the presence of fiber hairs on the spring ring increases thrombosis and achieves a more rapid embolic effect. The presence of the fiber hairs can increase the interaction between the spring coil and blood, promote the aggregation of platelets and fibrin along the fiber hairs, and accelerate the aggregation of blood flow to form thrombus. This immediate embolic effect helps to rapidly block blood flow, reduce pressure and risk of rupture in the diseased area, and promote thrombosis. Meanwhile, due to the reduction of the embolic coil, not only the operation cost can be reduced, but also the operation time and the pain of a patient can be reduced.

The prior art coil fiber wool is shown in fig. 1, and in this process, in order to enable the fiber wool to be uniformly distributed on the spring, the prior art manufacturing method is shown in fig. 2: the spring 3 is straightened by winding one end of the spring 3 more than once around the holding element 5, then passing the other end of the spring 3 under the first upright 61 and winding more than once around the second upright 62, thereby fixing both ends of the spring. Next, by moving the anchoring means 6 to the right, the spring 3 continues to be straightened and eventually the anchoring means 6 is locked in the desired position, after which the fibre fleece 4 is hung up against the straightened spring 3 as desired. The method can adjust the position and locking state of the anchoring mechanism 6 according to the requirement and adapt to springs 3 with different lengths, thereby realizing stable and reliable fixing effect. However, this fixation has some drawbacks.

The requirement of a fixed length at both ends of the spring 3 during the fixing increases the complexity of the fixing. This requires precise control of the fixing position and length of both ends of the spring 3 at the time of fixing, which increases the difficulty of operation.
