Description

Memory self-returning suturing nail

Technical Field

The utility model relates to the technical field of medical tools, concretely relates to memory is from power of returning and sews up nail.

Background

In a surgical operation, a designated part of a designated human body needs to be cut, and the cut part needs to be sutured, and the existing methods include the following steps: firstly, the traditional suture is slow in suture speed, the suture cannot be performed in a part of narrow space, the suture time is too long, and the wound is slow to heal; the vascular clip has large volume, is easy to slip frequently and cannot suture the sheet tissue; thirdly, glue is used for bonding and sewing, the application surface is narrow, the glue is only suitable for body surface application, and a plurality of tissues in the body cannot be used; fourth, sew up the cut part through the anastomat cooperation nail, it is firm to sew up, but because the section shape of nail foot and tie-beam is generally rectangle, to the unit area pressure of tissue too big, it is hard and destroy the tissue to pierce through the tissue, still often appear because of the uneven not in-place circumstances of sewing up that the dynamics of manual operation leads to, when sewing up not in-place the cut part can the hemorrhage phenomenon, in addition, in the physical suture of carrying out human or other animal internal operations, for example internal blood vessel suture, the suture of lung edge, wound suture after tumour excision, the suture of small intestine edge, when the suture of large intestine edge etc. was used, still can appear the medical accident that the nail drops and injures other tissues.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, a memory self-resilience stitching nail is provided, and the purpose is as follows: alleviate the unit area pressure to the tissue, avoid destroying the tissue, ensure to pierce through the tissue more laborsavingly, avoid because of the sewing off-position condition that the dynamics of manual operation is inhomogeneous leads to, avoid impaling the medical malpractice of other tissues after droing.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

a memory self-return suturing nail comprises a suturing nail back rod and at least two suturing nail feet, wherein the at least two suturing nail feet are arranged on the same side face of the suturing nail back rod, a nail shoulder is arranged between each suturing nail foot and the suturing nail back rod, and the shape of the nail shoulder is arc-shaped;

the cross sections of the suturing nail back rod, the at least two suturing nail feet and the at least two nail shoulders are all arc-shaped;

the suturing nail back rod, the at least two suturing nail feet and the at least two nail shoulders are made of memory alloy;

the end faces of the tail ends of at least two suture nail feet are inclined planes, and the included angle between each inclined plane and the side face of each suture nail foot is thirty degrees to sixty degrees.

Preferably, the angle between the inclined surface and the side surface of the foot of the staple is forty-five degrees.

Preferably, the number of the suture nail foot and the nail shoulder are two

Through the technical scheme, the cross sections of the suturing nail back rod, the at least two suturing nail feet and the at least two nail shoulders are all arc-shaped, and the arc-shaped cross sections can reduce the pressure of the memory self-returning suturing nail on the unit area of the tissue, so that the tissue is prevented from being damaged; the end surfaces of the tail ends of the at least two suture nail feet are inclined planes (namely the tail ends of the two suture nail feet are inclined feet), and the suture nail feet with the inclined end surfaces can ensure that the tissue can be penetrated more easily; the suturing nail back rod, the at least two suturing nail feet and the at least two nail shoulders are made of memory alloy, the memory automatic reset function can unify standard suturing thickness, and the condition that suturing cannot be achieved due to uneven force of manual operation is avoided; the automatic reset avoids the medical accident that the memorized self-restoring suturing nail pierces other tissues after falling off.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The following describes the embodiments of the present invention in further detail with reference to the schematic drawings.

As shown in fig. 1, 2, 3 and 4, the memory self-returning suturing nail comprises a suturing nail back rod 1 and two suturing nail feet 2, wherein the two suturing nail feet 2 are arranged on the same side face of the suturing nail back rod 1, a nail shoulder 3 is arranged between each suturing nail foot 2 and the suturing nail back rod 1, and the nail shoulder 3 is in the shape of a circular arc.

The cross sections of the suturing nail back rod 1, the two suturing nail feet 2 and the two nail shoulders 3 are arc-shaped, the pressure of the memory self-returning suturing nail on the unit area of the tissue can be relieved through the arc-shaped cross section design, and the tissue damage is avoided.

The suturing nail back rod 1, the two suturing nail feet 2 and the two nail shoulders 3 are made of memory alloy, the memory automatic reset function can unify standard suturing thickness, the condition that suturing cannot be achieved due to non-uniform force caused by manual operation is avoided, the medical accidents that the memory self-reset suturing nail penetrates other tissues after falling are avoided by automatic reset, in addition, the memory alloy is specifically NiTi shape memory alloy, and the NiTi shape memory alloy has the characteristics of high specific strength, wear resistance, corrosion resistance, no magnetism, good biocompatibility and the like, and also has peculiar shape memory performance and super-elasticity performance, so that the automatic reset capability and the biocompatibility of the memory self-reset suturing nail are further ensured.

The end surfaces of the tail ends of the two suture nail feet 2 are the inclined surfaces 21, namely the tail ends of the two suture nail feet are the inclined surfaces, the suture nail feet with the end surfaces of the inclined surfaces can ensure that the suture nail can penetrate through tissues more easily, and the included angle between the inclined surfaces 21 and the side surfaces of the suture nail feet 2 is forty-five degrees, so that the penetrating power of the memory self-return suture nail is further ensured.

Above be exactly a structural feature and the effect of memory self-power of returning and sew up nail, its advantage: the pressure to the unit area of tissue is reduced, the tissue is prevented from being damaged, more labor is saved when the tissue is penetrated, the condition that the suture cannot be in place due to the uneven force of manual operation is avoided, and the medical accident that other tissues are pierced after falling off is avoided.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
