Suturing device for implant and suturing method thereof

Abstract

The invention discloses a suturing device and method for an implant. The suturing device comprises a double-head needle, a control part, a first machine needle driving assembly, a second machine needle driving assembly and a feeding assembly, wherein the first machine needle driving assembly, the second machine needle driving assembly and the feeding assembly are in communication connection with the control part, and the control part is used for controlling the first machine needle driving assembly, the second machine needle driving assembly and the feeding assembly to move; the double-head needle is provided with a needle hole used for allowing a suture line to penetrate through; the first machine needle driving assembly and the second machine needle driving assembly are arranged on the two opposite sides of the double-head needle respectively, and a suture gap for a to-be-sutured piece to pass through is formed between the first machine needle driving assembly and the second machineneedle driving assembly; the first machine needle driving assembly and the second machine needle driving assembly can be used for clamping and releasing the double-head needle, and can drive the double-head needle to do reciprocating motion along a first path so as to suture the to-be-sutured piece. The suturing device can reduce the labor cost and improve the production efficiency.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a suturing device for implants and a suturing method thereof. Background technique [0002] Implants are commonly used in minimally invasive interventional medical devices to treat certain diseases of human organs, such as the use of covered stents to treat diseases such as thoracic / abdominal aortic aneurysms. The implant generally includes a bare stent and a reinforcement layer at least partially covering the bare stent, and the reinforcement layer and the bare stent need to be stitched into shape. [0003] Due to the limitations of the stitching process of the reinforcement layer and the bare bracket, which requires precise positioning, small needle holes, three-dimensional stitching, and special and firm thread node knotting methods, the current manual stitching method is mainly used, which will lead to difficulties in product quality consistency. Guaranteed, and manual sewing ...

Problems solved by technology

[0003] Due to the limitations of the stitching process of the reinforcement layer and the bare bracket, such as precise positioning, small needle holes, three-dimensional stitching, and special and firm thread node knotting methods, the current manual stitching method is mainly used, which will lead to difficulty in product quality consistency. Guaranteed, and manual sewing makes the labor input cost higher and the production efficiency lower

On the other hand, due to the structural characteristics and quality requirements of the covered stent, as well as its roughly tubular shape, the automatic suture equipment in the traditional industrial sewing machine system cannot meet the suture requirements of the reinforcement layer and the bare stent
