Description

Suture structure and suture assembly

Technical Field

The invention relates to the technical field of surgical sutures, in particular to a suture structure and a suture knot component.

Background

Clinically, surgical operation sutures are special threads for ligation hemostasis and suture hemostasis and tissue suture, and are mainly divided into two types, one is a non-absorbable thread, and the other is an absorbable thread. Non-absorbable sutures are sutures that are not absorbable by the tissue, which require removal of the suture after suturing. And absorbable suture is the suture that can be absorbed by the tissue, so need not take out stitches, divide into again according to material and absorption degree difference: catgut suture, chemically synthesized suture and pure natural collagen suture.

The catgut is made of the sheep intestines of animal sheep, contains collagen components, can be absorbed and degraded, does not need to be removed after being sewn, and is characterized by being hard, needing to be soaked by saline water when in use, and needing to be preserved by a protective solution within the period of validity, otherwise, once the protection of the protective solution is lost, the tension of the catgut cannot be effectively guaranteed, the absorption time is uncertain after being implanted into a human body, and the catgut has serious tissue rejection reaction. Modern medical catgut is divided into chromium-made catgut and plain-made catgut, the chromium-made catgut is prepared by soaking raw material catgut casing in chromide solution, and the plain-made catgut is prepared by treating raw material catgut casing without chromide because of the green color.

The chemical synthetic thread is a high molecular material prepared by adopting the existing chemical technology, is polymerized by artificial metabolites (glycolic acid and lactic acid), is prepared by the production process of spinning, stretching, coating and other procedures, has the absorption mode of hydrolysis, and has the advantages of convenient operation and predictable absorption time; the absorption time of the suture is closely related to the water content of the suture, the absorption time is short when the water content is high, and the absorption time is long when the water content is low, so the requirements on production and storage environments are high; until now, because the main component is chemical substances and contains chemical coatings, incomplete absorption still exists, and slight tissue rejection reaction exists.

The pure natural collagen suture is a natural forming material and is prepared by adopting a biological principle, wherein the collagen accounts for 93 percent, the elastin accounts for 3 percent and the fat accounts for 4 percent, and no additional chemical components are doped in the production process, so that the pure natural collagen suture is an original ecological protein material. The main component is type I collagen, so that the collagen can provide sufficient nutrition for wound healing after being used for wound suturing, and has the excellent characteristics of complete absorption, no scar, convenient use, good biocompatibility, no tissue rejection reaction and proper absorption time through clinical tests and scientific detection.

However, in surgical operation, there are many needles for suturing wounds at intervals regardless of the absorbable or non-absorbable thread, and in order to ensure the consistency and tightness of the suture, in general, when performing multi-needle intermittent suture, a plurality of sutures are sequentially sewed along the wound to be sutured, and after all the sutures are sewed, the wounds are sequentially and respectively tied. However, in the actual suture operation, it is found that it is difficult to distinguish whether two knotted ends are the same suture due to more suture threads, and when the two knotted ends are not the same suture, secondary suture is required, which results in prolonged operation time, increased operation risk, and the tissue is easily subjected to secondary cutting of the suture, especially for the tissue with fragile texture, and further affects subsequent wound healing.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 to 2, the present embodiment provides a suture assembly, which includes a plate body 1, a suture needle 2 and a suture structure 3, and there are two embodiments: the first embodiment is a single-plate eight-needle eight-thread, and referring to fig. 1 in particular, the suture structure includes a plate 1, at least two stitches 2 and a suture structure 3, the suture structure 3 includes at least two sutures 31, the at least two sutures 31 may be present independently, and the sutures 31 of the suture structure 3 are uniformly and correspondingly connected to multiple ends of one of the stitches 2; it is easy to understand that the present embodiment is not limited to a single board eight-pin and eight-wire manner, but a single board three-pin and three-wire manner, or a single board one-pin and multiple-wire manner may also be adopted. Referring to fig. 2, the suture structure 3 includes a plate body 1, a needle 2 and a suture structure 3, in this embodiment, the suture structure 3 includes at least two sutures 31 connected to each other in sequence and connected to the end of the needle 2. It will be appreciated that the plate 1 in this embodiment is only intended to carry the needle 2 and the suture arrangement 3, and that this is not essential.

As shown in fig. 3 to 5, the present embodiment is an improvement of the suture structure 3, in which at least two ends of each suture 31 of the suture structure 3 are provided with knotting marks 31a, and the knotting marks 31a on a part of the at least two sutures 31 are different from the knotting marks 31a on another part of the sutures 31, and by providing the knotting marks 31a on at least two ends of each suture 31 of the suture structure 3, when the suture 31 is sequentially passed through tissues on both sides of a wound, the knotting marks 31a on both ends thereof can protrude from the tissues to be sutured so that a medical staff can observe whether the knotting marks 31a on both ends of the suture to be knotted are consistent, and if they are consistent, it is indicated that the suture 31 belongs to the same suture 31, and the wound is sutured after being knotted. In this embodiment, the knotting marks 31a on some of the sutures 31 may be the same, the knotting marks 31a on some of the sutures 31 may be different, or the knotting marks 31a on any two of the sutures 31 may be different, when only some of the sutures 31 have different knotting marks 31a, the sutures 31 with different knotting marks 31a may be alternately sutured, for example, a suture 31 with a first knotting mark 31a at a first suturing point, a suture 31 with a second knotting mark 31a at a second suturing point, a suture 31 with a first knotting mark 31a at a third suturing point, a suture 31 with a second knotting mark 31a at a fourth suturing point, and so on, two adjacent sutures 31 may be effectively distinguished by the knotting marks 31a, thereby avoiding two adjacent sutures 31 that are most likely to have a knotting error. This is most effective when the knotting indicators 31a on any two of all the sutures 31 are different, which facilitates the differentiation of multiple sutures 31 at any suture point, and this is preferred in this embodiment.

It should be noted that, in the actual suturing process, when the first embodiment of this embodiment is adopted, each suture 31 is only used for single-point suturing at the wound, and a plurality of sutures 31 are sequentially sutured at a plurality of points at the wound, and when the second embodiment of this embodiment is adopted, each suture 31 is still only used for single-point suturing, which is different from the first embodiment in that after each suture point is threaded with a suture 31, the suture 31 needs to be cut and then the second suture point is sutured, and the medical staff can accurately cut between two adjacent sutures 31, and in order to facilitate the cutting, a cutting mark can be designed at the connecting position of two sutures 31, for example, a specific color is marked at the cutting position. It should be understood that the present embodiment is not limited to only providing the knotting marks 31a at both ends of each suture 31, but may also provide the knotting marks 31a on the entire suture 31 or provide the knotting marks 31a only on the portion of the suture 31 to facilitate the medical staff to distinguish the head of the suture 31 to be knotted.

The knotting mark 31a in this embodiment can be realized by color, and if the color of any two knotting marks 31a on the suture 31 is different, in actual operation, two ends of the suture 31 having the same color are knotted. In order to improve the accuracy of the distinction, it is generally not preferable to use the knot mark 31a on the suture 31 in red color, which is intended to avoid color confusion with blood. It is easy to understand that in the present embodiment, the color of each suture 31 may be set differently in actual operation, or the color of part of the sutures 31 may be the same and the color of part of the sutures 31 may be different. When a color is used as the knotting indicator 31a, the entire suture 31 may be set to a specific color, or only a portion of the suture 31 may be set to a specific color, such as a plurality of marker rings arranged at intervals in sequence along the length of the suture 31, and the marker rings on different sutures 31 may have different colors.

In the actual sewing process, since the sewing thread 31 is easily contaminated by blood to increase the difficulty in distinguishing, as shown in fig. 3, in this embodiment, not only a plurality of marking rings are sequentially arranged at intervals along the length direction of the sewing thread 31, but also the widths of the marking rings on any two sewing threads 31 are different, and when knotting is performed, whether the sewing threads 31 are the same can be judged by the widths of the marking rings. As shown in fig. 4, in this embodiment, the distance between two adjacent marking rings on each suture 31 may be set to be different from the distance between two adjacent marking rings on another suture 31, and when knotting, whether the two adjacent marking rings are the same suture 31 may be determined by the distance between the marking rings. It is understood that the embodiment can use the marking rings with different widths on different sutures 31 to distinguish the sutures 31 or the marking rings with different distances on different sutures 31 to distinguish the risks, and can also use the marking rings with different widths and distances on different sutures 31. Moreover, when the marking ring of the above mode is adopted, the marking rings on different sutures 31 can adopt the same color or different colors, wherein, different colors are preferably adopted in the embodiment, so that medical personnel can distinguish through the colors or the widths and/or the intervals of the marking rings when knotting, and the accuracy and the rapidness of distinguishing are favorably improved.

Since the use of the marking ring necessarily introduces new components, such as pigments, which more or less have a certain effect on the recovery of the wound tissue, in order to minimize the above effect, the suture 31 of the present embodiment is woven from at least two strands, and one strand of each suture 31 forms the knotting mark 31a, which is advantageous for minimizing the effect of introducing the new components.

In order to further avoid introducing new components, as shown in fig. 5, the stitches 31 of the present embodiment include a woven portion woven by multiple strands as a whole and discrete portions located at both ends of the woven portion and formed by the multiple strands being separated independently, the discrete portions form the knot mark 31a, and the number of discrete portions on each of the stitches 31 is different from the number of discrete portions on the other of the stitches 31. In the present embodiment, the multiple strands at the two ends of the stitches 31 are set in a dispersed state, and the amount of dispersion is controlled, which can make the amount of dispersion of the multiple strands at the two ends of each stitch 31 the same, for example, the stitches 31 with non-dispersed multiple strands (the amount of dispersion of the multiple strands can be considered to be one) can be used at the first stitch point of the wound, the stitches 31 with dispersed multiple strands into two can be used at the second stitch point of the wound, the stitches 31 with dispersed multiple strands into three can be used at the third stitch point of the wound, and so on to distinguish the multiple stitches 31; in addition, different numbers of the stitches 31 may be alternately sewn on the plurality of sewing points in sequence, for example, the stitches 31 with the non-dispersed strands may be used at the first sewing point of the wound, the stitches 31 with the non-dispersed strands may be used at the second sewing point of the wound, the stitches 31 with the non-dispersed strands may be used at the third sewing point of the wound, the stitches 31 with the non-dispersed strands may be used at the fourth sewing point of the wound, and the stitches 31 with the dispersed strands may be used at the fourth sewing point of the wound.

According to the invention, the knotting marks 31a are arranged at the two ends of each suture 31, and the different marks of the sutures 31 of two adjacent sutures 31 are controlled in the suturing process, so that medical workers can judge whether two suture ends to be knotted are the same suture 31 according to the knotting marks 31a, the knotting error between two adjacent sutures 31 is avoided, the convenience for distinguishing the medical workers is improved, the suturing time is shortened, the surgical risk is reduced, and the secondary suturing caused by the knotting suture 31 error is also avoided.

The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
