Description
Technical field
The utility model is related to skin surface wound suturing skill field, more particularly to a kind of pull fastening type stitching unstrument.
Background technology
Pull fastening type stitching unstrument（Also referred to as needleless stitching unstrument or needleless pull fastening type stitching unstrument）It is a kind of utilization skin itself
Power carries out skin surface wound the surface suture tool of noninvasive suture, and with hurtless measure scar, inflammatory reaction is light, healing is beautiful
The advantages that sight, has the trend of substitution needlework sewing-up cut completely.
If China Patent No. is a kind of connection structure of suture pulling buckle disclosed in " ZL 2015207840700 ", used
Two medical non-woven fabric adhesive tapes are first pasted the skin surface for being fixed on wound both sides by Cheng Zhong respectively；Then, by the bundle of two pulling buckles
What band was each passed through corresponding lock leads groove；Then the band for reversely pulling two pulling buckles, to pull skin to wound center
Line is drawn close, and makes the parallel close apposition of wound both sides skin edge, to complete the needleless suture of wound.
But the connection structure of this suture pulling buckle still has shortcoming, the reason is that, it is led groove and be set as level and runs through
Lock, and the corresponding thickness for leading recess region in lock top is larger, during band passes through, the amplitude of upward flexible deformation
It is minimum, thus, groove is led to enable band to pass through, the height of the ratchet of band need to be arranged smaller, and this can reduce spine
The clamping force of tooth and pawl to reduce pulling force between two substrates, and reduces sewing effect.It is opened up in addition, leading groove level, meeting
Making band that the bottom surface for the part for leading recessed trough be passed through to connect patch with substrate therefore, need to be first by band before the end of band is clamped
End and substrate separation, and this can influence to suture efficiency.
Utility model content
The main purpose of the utility model is to propose a kind of pull fastening type stitching unstrument, it is intended to improve suture quality.
To achieve the above object, the utility model proposes a kind of pull fastening type stitching unstruments, including are respectively used to be pasted onto wound
The first adhesive tape and the second adhesive tape of both sides skin surface, the first adhesive tape and the second adhesive tape are installed with outwardly extending
One lock and the second lock, the first adhesive tape and the second adhesive tape correspond to the second lock and the position of the first lock is installed with respectively
First spine bar and the second spine bar, the first lock and the second lock offer first passed through for the second spine bar and the first spine bar respectively
It opens in the region of guide groove and the second guide groove, the first lock the first guide groove corresponding with the top of the second lock and the second guide groove
Equipped with the first escape groove and the second escape groove for extending through the first guide groove and the opposite end face of the second guide groove, the first spine bar and
Second spine bar passes through the part of the second guide groove and the first guide groove to have outwardly extending first ratchet and the second ratchet, the first spine
Tooth and the second ratchet can distinguish the lock of hook second and first and latch opposite end face, to provide the first lock and the second lock
Opposite locking pulling force.
Technical solutions of the utility model are oriented in the first lock the first guide groove corresponding with the top of the second lock and second
The region of slot offers the first escape groove and the second escape groove through the first guide groove and the opposite end face of the second guide groove, can be
In the case of having substantially no effect on the first lock and the second lock overall construction intensity, reduces the first lock and the second lock is located at the
The thickness of one guide groove and the second guide groove upper area part, to improve the flexible deformation amplitude in the region, to ensure
On the basis of first spine bar and the second spine bar pass through, the height and length of the first ratchet and the second ratchet are done more,
And then the hook intensity of the first ratchet and the second ratchet and the opposite end face of second the first lock of lock is improved, finally improve first
Locking pulling force between lock and the second lock, and improve sewing effect.
