Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a minimally invasive fascia closer.
Background
For minimally invasive surgery, the perforation on the human body after the surgery is generally sutured on the outer skin, and because the caliber of the perforation is small, no way is provided for internal suturing, so that the perforation heals slowly and heals infirm;
In the prior art, the patent number is CN201611024846.4 (minimally invasive fascia closer), wherein a protective cover 5-1 and an elastic piece 5-2 connected with the protective cover are provided, and when a wire feeding needle 3 passes out of a wire feeding channel 4, the needle tip of the wire feeding needle is propped against the inner side surface of the protective cover 5-1, so that the puncture of the inner organ of a patient caused by the sharp puncture of the wire feeding needle 3 is avoided. However, when the needle tip of the wire feeding needle 3 is necessarily pushed against the inner side surface of the protective cover 5-1 in an inclined manner and the protective cover 5-1 is pushed obliquely downwards to deform the elastic piece 5-2, as the elastic piece 5-2 is an elastic sleeve, when the protective cover 5-1 is pulled obliquely downwards to the elastic piece 5-2, the deformation amount around the elastic piece 5-2 is inconsistent and the protective cover 5-1 is inevitably inclined due to uneven stress, so that the needle tip of the wire feeding needle 3 is not stably pushed against the protective cover 5-1 and even slides to enable the needle tip of the wire feeding needle 3 to deviate from the protective cover 5-1, thereby the risk of piercing the elastic piece 5-2 and injuring internal organs of a patient exists.
