Further, as an optimization mode, the first thread-off slit 4 is formed, so that the structural strength and the structural stability are reduced, and therefore, the reinforcing ribs 5 are arranged on the outer wall of the internal stitching section 2, and the reinforcing ribs 5 transversely span the upper area and the lower area of the hole 3, so that the connection strength between the outer wall below the hole 3 and the outer wall above the hole 3 is increased.
Furthermore, as an optimization mode, the non-connecting end of the internal suture section 2 can be of an elbow structure, the elbow structure is of a J shape, wherein the connecting end of the internal suture section 2 and the external expansion section 1 is of an arc structure, smooth transition connection is realized, the structure between the connecting end and the non-connecting end of the internal suture section 2 is preferably of a straight cylinder structure, the structure can be of an arc structure with small curvature, abdominal wall tissues can enter the internal suture section 2 through the through holes 3, the number of the through holes 3 in the elbow structure can be 1 or 2, and of course, the number and the size of all the through holes 3 in the elbow structure are mainly based on the fact that the number and the size of human body puncture holes are not too large, and when the internal suture is used for suturing other large-volume biological tissues, the number and the size of the through holes 3 can be correspondingly increased or increased.
Further, as an optimization mode, when the elbow structure is used for suturing human tissues, the number of the through holes 3 is preferably 1, namely, the through holes 3 are arranged on the side wall of one side of the internal suturing section 2 in the invention. The suturing process at this time may be that the body suture section 2 is inserted into the abdominal puncture hole, the lower end of the body suture section 2 passes through the subcutaneous, fascia and peritoneum, the abdominal tissue at one side enters the interior of the body suture section 2 through the via hole 3 at one side on the body suture section 2 by pressing the abdominal wall or pressing the suture device, then the suture thread passes through the abdominal tissue at one side by the suture needle, and is placed in the abdominal tissue, the suture needle is pulled out, the suture thread is kept in a loose state, then the suture device is rotated, the abdominal tissue at the interior of the body suture section 2 is pulled out, the via hole 3 is rotated to the other side, the abdominal tissue at the other side enters the interior of the body suture section 2 through the via hole 3, then the suture needle passes through the abdominal tissue at the other side, then the suture device is rotated again, the abdominal tissue at the interior of the body suture section 2 is pulled out again, and the suture device is gradually pulled out, the suture thread between the abdominal tissues at both sides is pulled out through the via hole 3 in the process of pulling out the suture device, and the suture thread at both sides of the abdominal tissue is pulled out after the suture device is pulled out.
The straight-head structure and the elbow structure can be used interchangeably in their use, except for slight differences in the method of operation. Under the same diameter condition, the elbow structure can enable more abdominal wall tissues to enter the product than the straight head structure, after the part needing to be sutured is threaded through one side, the other part needing to be sutured is threaded through rotating, and finally suturing is achieved. One more method than the straight structure is to use the elbow structure, place the suture line to the position to be sutured through the channel in the middle of the product, then puncture the position to be sutured through the puncture needle, draw out the suture line, then rotate, puncture and lead the position to be sutured on the other side with the puncture needle after the rotation.
In the straight head structure, the elbow structure and other deformation structures, in order to facilitate the abdominal wall tissues to enter the internal suture section 2, the side wall of the internal suture section 2 provided with the via hole 3 is of an arc-shaped structure, the diameter of the arc-shaped structure gradually decreases from outside to inside, namely the upper end of the via hole 3 is closer to the abdominal wall tissues than the lower end, the coverage area of the via hole 3 is increased, more abdominal wall tissues can enter from outside to inside, and the suture work is facilitated. Furthermore, as an optimization mode, the through hole 3 is obliquely arranged on the side wall of the internal suturing section 2 towards the inside of the body, so that the tissue of the abdominal wall can enter the internal suturing section 2.
In order to facilitate the medical operator to accurately puncture the abdominal wall tissue, namely, to facilitate the suture work of the suture needle, the suture cavity is internally provided with a guide channel 6 for the suture needle to pass through, and the suture needle pierces the abdominal wall tissue positioned in the suture cavity after passing through the guide channel 6. The guide channels 6 can be integrally formed with the suture cavity, can be prefabricated and then installed on the suture cavity, the number of the guide channels 6 is the same as that of the through holes 3, and are positioned above the through holes 3, the outlet direction of the guide channels 6 faces the side wall of the inner suture section 2 opposite to the side wall of the guide channels 6, namely the problem that the outer wall of the suture device is damaged due to the fact that the needle tip of a sewing needle directly pierces the side wall of the suture device is avoided, particularly when the material hardness of the suture device is insufficient, the sewing needle easily pierces the outer wall, and at the moment, the internally-sutured suture device cannot achieve a good protection effect.
Further, as an optimization mode, in order to facilitate the thread-off, the guide channel 6 is provided with the second thread-off slit 7, the straight structure is provided with the first thread-off slit 4, the finger structure is not provided with the second thread-off slit 7 any more, the elbow structure is not provided with the first thread-off slit 4, in order to facilitate the thread-off operation in the elbow structure, the second thread-off slit 7 is preferably arranged on the guide channel 6 of the elbow structure, the suture abdominal cavity is sutured through the guide channel by using the puncture needle, the thread is separated from the slit at this time, the abdominal wall tissue is pierced by using the puncture needle after the suture device is rotated, the thread is led out to a proper length through the guide channel, and then the thread is separated from the slit.
Furthermore, as an optimization mode, the suture cavity and the guide channel 6 are made of medical transparent materials.
Further, as an optimization, for the convenience of hand-held operation, the end of the non-connecting end of the extracorporeal expansion section 1 is connected with the annular flange 8.
