Detailed Description
In order that the above-described aspects may be better understood, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Example 1
As shown in fig. 1-4, the present embodiment provides an incision closure appliance. The incision closer comprises two clamping bodies 1 which are oppositely arranged, wherein the two clamping bodies 1 are movably connected and can be switched between an opening state and a closing state, one end of one clamping body 1 is provided with a plurality of stitching parts 11 which are transversely spaced, wherein 'transverse' refers to the length direction of an incision to be closed, as shown in fig. 1, one end of the other clamping body is provided with a matching part 14 matched with the stitching parts, and the matching part 14 is connected to tissue to be stitched so as to match the stitching parts to pass through the tissue to be stitched to enable the incision to be closed. The suturing portion 11 has a cylindrical structure, such as a suturing needle or a suturing tooth, and the length of the suturing portion 11 is greater than the thickness of one side of the tissue to be sutured, so that the suturing portion 11 can cause a connection between two stacked layers of tissue to be sutured, thereby providing conditions for healing of the incision. In this embodiment, in order to facilitate the manufacturing of the incision closer and to increase the closing effect, the engaging portion 14 has the same structure as the suture portion as shown in fig. 2.
When the two clamping bodies 1 are in the open state, an open space is formed between the suture part 11 and the matching part 14 so as to be capable of accommodating tissues to be sutured containing incisions to be sutured, when the two clamping bodies 1 are in the closed state, the matching part 14 is connected to the tissues to be sutured so that the matching suture part 11 can penetrate through the tissues to be sutured to close the incisions, and at the moment, the distance between the root parts of the matching part 14 and the root parts of the suture part 11 is 60% -80% of the thickness of the tissues to be sutured. Preferably 75% of the thickness of the tissue to be sutured during actual use. It should be noted that the thickness of the tissue to be sutured is the thickness of the tissue to be sutured after the two sides of the incision are overlapped, the thickness of the tissue to be sutured is double the wall thickness of the small intestine when suturing the small intestine, and double the wall thickness of the stomach when suturing the stomach, therefore, in the practical application process, the thickness of the tissue to be sutured is determined according to the specific clamping position, namely, different types of incision closers are needed to be used for suturing different positions.
According to the incision closer provided by the embodiment, as the two clamping bodies 1 are movably connected and can be switched between the opening state and the closing state, when the two clamping bodies 1 are in the opening state, the opening space is formed between the matching part 14 and the stitching part 11, so that the tissue to be stitched containing the incision to be closed can be contained, when the two clamping bodies 1 are in the closing state, the matching part 14 is connected to the tissue to be stitched so that the stitching part 11 can penetrate through the tissue to be stitched to enable the incision to be closed, and further rapid stitching of the incision can be realized, and the stitching time is saved. In addition, in the process of suturing, the incision closer does not need to clamp the tissues to be sutured of a certain length of incision to be closed, and only needs to suture a row of tissues to be sutured through the suturing part 11 after the tissues to be sutured are overlapped, so that the problem of stenosis after incision suturing is avoided.
Moreover, in the closed state, the distance between the root of the matching part 14 and the root of the suturing part 11 is 60% -80% of the thickness of the tissue to be sutured, so that the reliability after suturing is improved under the condition of ensuring blood supply, and the situation that when the distance between the root of the matching part 14 and the root of the suturing part 11 is too large, the incision after suturing opens to cause leakage when passing through an object, and when the distance between the root of the matching part 14 and the root of the suturing part 11 is too small, the tissue to be sutured is sutured too tightly to cause blood flow in the tissue to be sutured to be dead is avoided.
As shown in fig. 2, each clamping body 1 includes a connecting portion 13 and a plurality of connecting rods 12, the connecting portions 13 of two clamping bodies 1 are connected in a relatively rotatable manner, the connecting rods 12 are arranged transversely at equal intervals, one ends of the connecting rods 12 are connected with the connecting portions 13, the other ends of the connecting rods 12 on one clamping body 1 are connected with the sewing portions 11 in a one-to-one correspondence manner, and the other ends of the connecting rods 12 on the other clamping body 1 are connected with the matching portions 14 in a one-to-one correspondence manner. Specifically, the stitching 11 in one clamping body 1 is alternately arranged with the mating 14 in the other clamping body 1, avoiding interference when the stitching 11 and the mating 14 are closed.
As shown in fig. 2-4, the incision closer further comprises a connection and state maintaining device 2, in this embodiment, the connection and state maintaining device 2 comprises a pivot 21, a spring 22 and a hinge seat 23 arranged on the connection portion 13 of the clamping body 1, the hinge seat 23 is provided with a through hole for accommodating the pivot 21, after the hinge seat 23 on the connection portion 13 of the clamping body 1 is abutted, the pivot 21 passes through the through hole, the two clamping bodies 1 can rotate around the pivot 21, the spring 22 is sleeved on the pivot 21, and two ends of the spring 22 are respectively abutted on the connection portions 13 on the upper portions of the two clamping bodies 1. When the spring 22 is in a compressed state, the two clamping bodies 1 are in an open state, and an open space is formed between the matching part 14 and the suturing part 11 so as to be capable of accommodating tissues to be sutured including incisions to be closed; when the spring 22 is in the reset state, the two clamping bodies 1 are in the closed state, the matching part 14 and the stitching part 11 are crossed to penetrate through the overlapped tissues to be stitched, the stitching part 11 and the matching part 14 stitch the two edges of the tissues to be stitched together, and the incision edges are grown together after a period of time due to sufficient blood supply of the tissues, so that the incision is closed. Thereby, the spring 22 plays a role of maintaining the state of ensuring that the two clamp bodies 1 are in the closed state.
Specifically, the connecting portion 13 includes a first connecting plate 131 and a second connecting plate 132 that are connected, the hinge seat 23 is disposed on the first connecting plate 131, the pivot 21 passes through the hinge seat 23 to enable the two first connecting plates 131 to rotate around the pivot 21, two ends of the spring 22 respectively abut against the first connecting plates 131 of the two clamping bodies 1, so that the connecting portions 13 on the two clamping bodies 1 can be connected in a relatively rotatable manner between an open state and a closed state, and the plurality of connecting rods 12 are arranged at equal intervals along the second connecting plate 132. In order to ensure that the spring 22 is in a compressed state when the incision closer enters the body and further the closer is in an open state, the connecting and state holding device 2 further comprises a connecting wire 3, two ends of the connecting wire 3 are respectively connected with the first connecting plates 131 of the two clamping bodies 1 to ensure that the spring 22 is continuously in a compressed state, and when the incision closer is closed, only the connecting wire 3 is needed to be cut off to ensure that the spring 22 is in a reset state. Thereby, the connection wire 3 plays a role of holding the two clamp bodies 1 in an opened state.
Of course, in order to further ensure that the connecting portion 13 remains in the closed condition when the incision closure is in use, barbs are provided on each of the suturing portions 11 to prevent tissue from sliding off the suturing portions 11 to open the incision.
Of course, the connection and state holding device 2 of the present invention has at least the function of holding the two clamp bodies 1 in the closed state.
Example two
The difference between this embodiment and the first embodiment is that the structure of the connection and state holding device 2 is different, as shown in fig. 5-6, in this embodiment, the connection and state holding device 2 is a connection tube 24, the connection tube 24 is opened up and down, and the connection tube 24 is sleeved on the connection portions 13 of the two opposite clamping bodies 1 in a sliding manner, so that the connection portions 13 can be connected in a relatively rotatable manner between an opened state and a closed state. Wherein the sliding of the connecting tube 24 can adjust the distance between the connecting rods 12 on the two connecting parts 13, and further adjust the distance between the root parts of the stitching parts 11 connected with the connecting rods 12. In the practical application process, the connecting portion 13 is made of an elastic material.
In order to keep the connecting portion 13 in a closed state when the incision closer is in use, the connection and state holding device 2 further comprises a clamping structure arranged between the connecting cylinder 24 and the connecting portion 13 of the clamping body 1. The clamping structure is constructed as a bulge and a groove matched with the bulge, wherein when the bulge is arranged on the connecting part 13, the groove is arranged on the connecting cylinder 24; when the projection is provided on the connecting tube 24, the groove is provided on the connecting portion 13, and when the connecting portion 13 is in the closed state, the projection is engaged with the groove, so that the connecting portion 13 is maintained in the state.
In order to prevent the connecting tube 24 from sliding out when sliding on the connecting portion 13, the connecting and status holding device 2 further comprises a fixing member 25, wherein the fixing member 25 is disposed at the top end of the connecting portion 13 of the clamping body 1, and the lateral width of the fixing member 25 is larger than that of the connecting tube 24, so that the sliding out of the connecting tube 24 is avoided.
Of course, in order to further maintain the connecting portion 13 in a closed state when the incision closer is in use, barbs are provided on each of the suturing portions 11 to prevent tissue from sliding off the suturing portions 11 to open the incision.
Example III
As shown in fig. 7 to 8, the difference between the present embodiment and the first embodiment is that the connection and state maintaining device 2 includes a bendable connecting piece 26 and a barb 111, and the connection portions 13 of the two clamping bodies 1 are respectively connected to both sides of the connecting piece 26, so that the connection portions 13 can be connected in a relatively rotatable manner between an open state and a closed state. Wherein the incision closer is in an open state when it is entered into the body, and when it is desired to close, the bendable connecting pieces 26 are kneaded inward, so that the angle of the connecting pieces 26 is reduced. In order to maintain the attachment portion 13 in a closed position during use of the incision closure, preventing the attachment 26 from opening, barbs 111 are provided on each of the sutures 11 to prevent tissue from sliding off the sutures 11 to open the incision.
