Detailed Description

The present application is described in further detail below with reference to the accompanying drawings.

Referring to fig. 1-4, an embodiment of the application discloses a minimally invasive fascia suture apparatus, which comprises a guide 1 and a puncture needle 2, wherein a puncture channel 11 and a guide channel 12 are arranged in the guide 1. The puncture channel 11 is used for inserting the puncture needle 2, and the guide channel 12 is used for passing the suture thread 4; the lower end of the guide 1 is provided with a suture cavity 13, and the suture cavity 13 is positioned on the path of the puncture channel 11 and is used for filling the skin 5 tissue on the suture cavity 13. The lower end of the guide channel 12 passes through the puncture channel 11, and the guide channel 12 extends to the outer wall of the guide 1. The bottom of the puncture needle 2 is provided with a perforation 21, and when the lower end of the puncture needle 2 is abutted against the lower end of the puncture channel 11, the perforation 21 is positioned on the path of the guide channel 12.

The upper end of the puncture needle 2 is connected with a needle handle 22, a limit bar 23 is arranged on the side wall of the needle handle 22, and a limit groove 111 for the limit bar 23 to be clamped in is arranged on the inner wall of the guide channel 12 so that the puncture hole 21 is aligned with the path of the guide channel 12. The lower end of the guide channel 12 is an arc-shaped channel, namely, when the puncture needle 2 is inserted into the bottom of the puncture channel 11, the perforation 21 is positioned on the path of the arc-shaped channel. In this embodiment, the arc center of the arc channel faces upwards, that is, the guide wire 3 is tilted upwards under the action of the material of the guide wire 3 and the arc channel after passing through the guide channel 12.

The stapler also comprises a flexible guide wire 3, which may be a stainless steel wire. The end of the guide wire 3 is provided with a hole for the suture 4 to pass through and be connected to the guide wire 3 in a binding way. When the puncture needle 2 is lifted, the guide wire 3 can be lifted out of the puncture channel 11 after being bent, the suture thread 4 passes through skin tissues, and the end, far away from the suture cavity 13, of the guide 1 is provided with a connecting handle 14. In other embodiments, suture 4 may be passed directly from guide channel 12 through perforations 21 without the use of guide wire 3.

Referring to fig. 4-12, the method of use thereof:

step 1: the guide 1 is inserted into the wound, and the suture cavity 13 of the guide 1 is directed towards the skin 5 tissue on one side of the wound, so that the skin 5 tissue on the side is squeezed into the suture cavity 13;

step 2: the puncture needle 2 is inserted into the puncture channel 11, and at the same time, the puncture needle 2 penetrates through the skin 5 tissue positioned in the suture cavity 13 to reach the bottom of the puncture channel 11, and the puncture 21 is positioned on the path of the guide channel 12;

step 3: the guide wire 3 is inserted into the guide channel 12 such that one end of the guide wire 3 passes through the perforation 21 and protrudes into the abdominal cavity outside the guide 1;

step 4: the puncture needle 2 is pulled out upwards, the guide wire 3 and the suture thread 4 are penetrated out of the skin 5 tissue positioned in the suture cavity 13, and then the guide 1 is penetrated out of the puncture channel 11; the guide 1 is then removed and separated from the suture 4;

step 5: the guide 1 is inserted into the wound after being turned again, and the suture cavity 13 of the guide 1 faces the skin 5 tissue at the other side of the wound, so that the skin 5 tissue at the other side is extruded into the suture cavity 13;

step 6: repeating the steps 2-4;

step 7: the suture thread 4 on the skin 5 tissue at both sides of the wound is knotted to complete the suturing.

Through the cooperation of the guide device 1, the puncture needle 2 and the guide wire 3, the skin 5 tissues at two sides of the wound can be conveniently and sequentially punctured with the suture thread 4 respectively, and the ends of the two suture threads 4 are respectively knotted and cut to finish the suturing; avoiding damage to tissue and organs in the abdominal cavity; and the whole equipment of the stitching instrument has simple structure and convenient operation, and can improve the working efficiency.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
