Detailed Description

In order to more clearly describe the present invention, the present invention will be further described with reference to the accompanying drawings.

As discussed in the background, in clinical practice, there is a varying degree of clearance between the casing bore and the casing, as the size of the casing bore is unlikely to be exactly the same as the outside diameter of the casing bore closure. The gap causes the needle to pass through only the edge of the side wall of the sleeve hole, the suturing effect is poor, and the barbed thread is easy to fall off from the part to be sutured. Based on the above, the utility model provides a sleeve hole suturing device with an air bag. Referring to fig. 1, 3 and 4, the opposite sides of the casing of the cannula obturator with air bag are provided with needle outlets, and an inflatable air bag 10 is arranged between the two needle outlets. During operation, the shell 2 is inserted into the sleeve hole, and then the air bag 10 is inflated. The air bag 10 expands to occupy the gap between the sleeve hole and the shell 2, the front end and the rear end of the sleeve hole are extruded, the sleeve hole deforms after being extruded, the distance between the front end and the rear end grows, and the width of the left end and the right end is narrowed and tightly attached to the needle outlet surface of the shell 2. The driving component drives the sewing needle 7 to penetrate out of the needle outlet hole to pierce the side wall of the sleeve hole, so that the sewing needle can pierce the middle part of the part to be sewn, the barbed wire can not fall off, and the sewing effect is good.

In the example, the front air bag and the rear air bag are communicated 101 through a communication part with the needle outlet holes with different heights, and the front air bag and the rear air bag can be expanded by inflating the inflating device 102 through a single air inlet hole; meanwhile, the sewing needle 7 cannot pierce the air bag 10 during the rotation process; the cross section of the front air bag and the cross section of the rear air bag after expansion are both semicircular and can be fully contacted with the side wall of the sleeve hole.
