Abstract

The invention discloses a full internal suturing device for tissue repairing, which can simply and rapidly achieve full internal suturing of injured tissues. The full internal suturing device includes7 parts comprising a first anchoring nail, a second anchoring nail, a suturing thread, an inner needle, an outer needle, a depth limiting pipe, and a handle; the handle includes a plurality of partssuch as a pushing rod; according to the full internal suturing device, the first anchoring nail, the second anchoring nail, and the suturing thread are pre-embedded in the outer needle, the outer needle carrying with the first anchoring nail, the second anchoring nail, and the suturing thread enters an interior of a tissue, and the depth limiting pipe can limit the depth that the outer needle is inserted into the tissue; the size of the anchoring nails is small, damage to a tissue surface due to the anchoring nails can be reduced during puncturing; the anchoring nails are fixedly positioned ina pipe cavity of the outer needle, and the risk that the anchoring nails are released during puncturing can be lowered; a doctor can position a suturing position twice; the center of the handle is ofa symmetrical structure, a 360-degree pushing operation can be achieved, and clinic operation of medical workers is facilitated.

Description

technical field

[0001] The patent of the present invention relates to a total internal suture device for tissue repair, which can easily and quickly realize the total internal suture of tissue damage. Background technique

[0002] Meniscus injury is a common knee joint sports injury, and its treatment methods vary according to the location, extent, and type of injury. Such as conservative treatment, partial resection, total resection, suture repair, meniscal prosthesis replacement, allogeneic meniscus transplantation, tissue engineering reconstruction, etc., each has its own application, and clinically, arthroscopy is usually used Lower meniscectomy and meniscus suture repair. Today, the importance of the biomechanical function of the meniscus is increasingly recognized, and increasing evidence supports the preservation of peripherally ruptured menisci, coupled with the importance of the meniscus in joint nutrition, lubrication, stability, load transfer, cushioning, proprio...

Examples

Embodiment 1

[0065] This implementation provides a full internal suture device for tissue repair. The suture device is composed of the first anchor, the second anchor, sutures, inner needles, outer needles, depth-limiting tubes and handles. Please refer to figure 1 . In this embodiment, the handle, the shape of the outer needle, the shape of the first anchor and the second anchor, and the number and size of the threading holes are only for illustration, and the shapes, numbers and sizes shown therein do not constitute patents for inventions. There are restrictions on the number and size of each component.

[0066] In this embodiment, the first anchor and the second anchor are different from the anchors of other staplers. The size of the anchor is smaller, and the shape is smoother, which is more suitable for penetrating tissue and positioning on the tissue surface. In this embodiment, a single anchor A total of two threading holes are set on the nail, and the positional relationship betwe...

Embodiment 2

[0077] This embodiment provides another total internal suture device for tissue repair. The difference between this embodiment and Embodiment 1 is that the curvature of the front end of the outer needle is different. Please refer to Figure 12 .

Embodiment 3

[0079] This embodiment provides another total internal suture device for tissue repair. The difference between this embodiment and Embodiment 1 is that the bending direction of the front end of the outer needle is different. Please refer to Figure 13 .
