Abstract

The invention discloses a rapid-fallen suturing nail, which is rapid to fall through a physiological reaction in a human body. The suturing nail comprises a connecting beam and nail pins, wherein the nail pins are connected to two sides of the connecting beam and extend downwards; and propelling piece, which extends downwards, is fixedly arranged on the front edge of the connecting beam. Compared with the prior art, the suturing nail disclosed by the invention has the advantages that 1. the propelling piece is driven by an edema effect generated after an operation on a human body, so that the suturing nail is driven to rapidly move away from the human body; 2. in coordination with the planar plate-shaped structure of the connecting beam, the suturing nail is prevented from sinking into skin of the human body, so that a phenomenon that the suturing nail is not easy to fall off is avoided; and 3. by virtue of blade-shaped structures matched on the nail pins, the suturing nail can better pierce tissues, so as to take an assisting effect on accelerating failing.

Description

Fast-falling formula suturing nail

Technical field

The present invention relates to a kind of suturing nail, more particularly, relate to a kind of fast-falling formula suturing nail.

Background technology

In surgical operation, needing to cut appointment human body appointed part, need to sew up the position of cutting, existing means simultaneously, is coordinate suturing nail to sew up cutting part by anastomat.Existing anastomat suturing nail, its overall structure is U-shaped, the cross sectional shape of nail foot and tie-beam is generally rectangle, postoperative suturing nail time that comes off is longer, and minority suturing nail not easily Automatic-falling, encounter the suturing nail that the long period do not come off, generally, hospital is needed to remove, increase time and the energy of patient, position due to suturing nail is positioned at body surface place, the long-time suturing nail do not come off, patient may entertain fluke mind, take off voluntarily, dismounting due to suturing nail has certain skill, patient is in unloading process, can drag down by force because of irritable psychology, and then cause infecting, application number is the patent of 201510546035X, disclose and a kind ofly follow closely the suturing nail that tape has bladed structure, the principle of foreign body is repelled by tissue self, coordinate the repulsion of bladed structure accelerating slit dowel.But this process according to the difference of different human body, can have different effects, that is may have more people after surgery the speed that comes off of suturing nail accelerate, but there is the speed that a minority comes off at suturing nail accelerates not obvious.

Summary of the invention

The object of the present invention is to provide a kind of fast-falling formula suturing nail being accelerated to come off by human physiological reaction.

Object of the present invention is achieved through the following technical solutions: it comprises tie-beam and is being connected the front of fine strain of millet along the projectile be installed with to downward-extension with the nail foot to downward-extension being connected to tie-beam both sides.

Compared to prior art, the invention has the advantages that: 1 by the edema effect of the postoperative generation of human body, drive projectile, and then drive suturing nail to accelerate to depart from human body, and the 2 plane tabular structures being connected beam, wall avoids suturing nail to be absorbed in skin, cause the situation of suturing nail difficult drop-off, 3 to arrange in pairs or groups bladed structure on nail foot, and suturing nail can better break and organize soon, auxiliary acceleration comes off.

Detailed description of the invention

Below in conjunction with Figure of description and embodiment, content of the present invention is described in detail:

As shown in figures 1-4: comprise tie-beam 1 and the nail foot 2 to downward-extension being connected to tie-beam 1 both sides, it is characterized in that: connecting the front of fine strain of millet along the projectile 3 be installed with to downward-extension.The nail foot 2 of tie-beam 1 both sides and tie-beam in conventional staple 1 and the position of following closely foot with act on substantially identical, difference is connecting the front of fine strain of millet along being provided with one piece of projectile 3 to downward-extension, the effect of projectile is set, in operation process, when using suturing nail, while suturing nail is fixing, skin edge is just close in the position of projectile, in general surgical operation is carried out, particularly after circumcision, skin edge there will be edema phenomenon, this process generally continues 3 ~ 7 days, projectile is by edema phenomenon, whole suturing nail is driven to move to skin edge, its acceleration is driven to come off.

As shown in Fig. 4,7 ~ 9: in general, described projectile 3 is platy structure or network structure or rod-like structure or hurdle grating structure.As long as can realize edematous tissue drive projectile motion structure can, wherein best with platy structure effect.

Described tie-beam 1 is platy structure.Because suturing nail entirety is less, general tie-beam is also more elongated structure, easily occur that tie-beam is embedded in skin, due under normal circumstances, suturing nail only has tie-beam to be exposed at skin surface, if tie-beam is also trapped in skin, and the general just bad position by perusal suturing nail and situation, and suturing nail also difficult drop-off, the later stage needs to coordinate operation to remove suturing nail.

Described platy structure is rectangle or oval or half elliptic.As long as generally can increase tie-beam 1 surface area structure can, wherein suitable with rectangle, be applicable to the connection of projectile on the one hand, processing also facilitates on the other hand.

In each nail foot 2, have at least a lateral edges to be bladed structure, make nail foot 2 in traveling process,

Lateral edges in bladed structure can cut and organize; Wherein, when the structure of two nail feet 2 is for only having a lateral edges to be bladed structure, the lateral edges in bladed structure 4 in two nail feet 2 is positioned at the same side.In order to reduce the resistance that suturing nail departs from, therefore nail foot is provided with bladed structure.

The cross section of described nail foot 2 is triangle or rhombus.This can adjust as the case may be, and such as cross section is olive-shapedly also to be fine.

The concrete case of structure is described effect of the present invention below

Here only contrast for suturing nail of the present invention and traditional structure suturing nail, because other surgical operations are less and more difficultly find volunteer, therefore carry out perform the operation (certain Wrapping annulus cuts operation result of use is also better) for Wrapping annulus cuts operation especially

In general, in order to ensure accuracy rate statistically, therefore respectively have selected 50 patient volunteers and carry out traditional operation, 30 patients use novel suturing nail to perform the operation, and add up respectively, and the suturing nail quantity of patient is roughly in 16 ~ 30 scopes.More than perform the operation and the structure of unexposed anastomosis staple

After 21 days, conventional staple and Novel suture are followed closely remaining suturing nail and are removed by formality, wherein in conventional staple, have 2 patient's statements to remove.

After 21 days, the conventional staple clean patient populations that do not come off is 12 people, and the Novel suture nail clean patient populations that comes off is 2 people.

Below for suturing nail described in conventional staple and the application is after 21 days, remaining situation:

	Surplus 1	Surplus 2	Surplus 3	Surplus 4	Surplus 5	Surplus more than 6
							Conventional staple	3	3	2	2	1	1
Novel suture is followed closely	0	0	0	0	0	0

In conventional staple, the patient that remaining suturing nail is maximum, leaves 8 suturing nails.

In sum, this product and conventional staple compare, have come off fast, hold caducous feature.

Although the present invention adopts specific embodiment and alternative thereof illustrate to the present invention and illustrate, only to should be appreciated that otherwise the variations and modifications deviated from scope of the present invention all can be implemented.Therefore, except being to be understood that the restriction of claim except being enclosed and condition of equivalent thereof, the present invention is not by the restriction of going up in all senses.
