Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 5, a skin wound closure device comprises:

the first sticker 1 is provided with a ratchet strip 10, and the ratchet strip 10 is provided with a ratchet 100;

the second sticker 2 is provided with a clamping portion 20, the clamping portion 20 is provided with a movable cavity 200 and an inserting groove 201 which penetrates through the clamping portion 20 and is communicated with the movable cavity 200, and the ratchet 10 can penetrate through the inserting groove 201 and is connected in the inserting groove 201 in a sliding mode;

fastener 3, the first end slidable of fastener 3 sets up in

activity chamber

200, and 3 second ends of fastener penetrate joint portion 20 and stretch out to the external world to being equipped with latch 30 on the first end of fastener 3, latch 30 can stretch into and wear the setting in slot 201, and latch 30 still can with 100 joint of ratchet or separation.

Specifically, the ratchet 10 is made of plastic material and has a certain flexibility, the ratchet 100 has a certain inclination angle, and the latch 30 is also arranged in an inclined manner corresponding to the direction of the ratchet 100; an easy-pulling plate 3a is arranged at one end of the clamping piece 3 extending out of the clamping part 20, and in a normal state, the first end of the clamping piece 3 is propped against the bottom of the movable cavity 200, and the clamping tooth 30 extends into the slot 201. When in use, the first patch 1 and the second patch 2 are firstly attached to two sides of a wound of a patient, then the ratchet strip 10 on the first patch 1 passes through the slot 201, the ratchet 100 is clamped with the latch 30, and the first patch 1 and the second patch 2 are connected with each other; and the ratchet strip 10 is pulled continuously, because the ratchet strip 10 has flexibility, after the ratchet strip 10 is displaced, the subsequent ratchet 100 is still clamped with the latch 30, the first patch 1 and the second patch 2 are also close to each other, the locking force to the wound skin is improved, and the latch 30 and the ratchet 100 are continuously clamped by the reaction force generated by the skin of the patient. If the position between the first sticker 1 and the second sticker 2 needs to be adjusted, that is, the locking force needs to be adjusted, the clamping piece 3 can be pulled to separate the clamping teeth 30 from the ratchet 100, so that the ratchet bar 10 is unlocked, the position of the ratchet bar 10 and the corresponding applied locking force are convenient to adjust, the clamping piece 3 is reset after the adjustment is finished, the clamping teeth 30 clamp the ratchet 100 again, and the ratchet bar 10 is locked again.

In the present invention, the second end of the clip member 3 can protrude from the side or top of the clip portion 20, and the ratchet 100 can be correspondingly disposed on the upper, lower or side end of the ratchet bar 10. In the embodiment in which the second end of the card member 3 protrudes from the side of the catching portion 20, the card member 3 can slide laterally; in the embodiment in which the second end of the card member 3 protrudes from the top surface of the card-holding portion 20, the card member 3 can slide in the up-down direction. In both embodiments, the position and the direction of the latch 30 can be designed correspondingly according to the position of the ratchet 100 on the ratchet bar 10, and the latch 30 and the ratchet 100 can be clamped and unlocked.

Further, in the preferred embodiment, the ratchet 100 is disposed on the side of the ratchet bar 10, the clamping member 3 slides up and down in the movable cavity 200, and the latch 30 is disposed on the side end of the clamping member 3. When the locking device is used, the easy-pull plate 3a at the second end of the clamping piece 3 is pulled upwards, so that the clamping teeth 30 can be separated from the ratchet 100, the ratchet bar 10 is unlocked, and the arrangement is that a larger implementation space is reserved for pulling the easy-pull plate 3a, so that convenience is provided for modifying the locking force.

Furthermore, the first end and the second end of the clip 3 are connected through a sliding column 31, the skin wound closure further comprises an elastic member 4, the elastic member 4 is located in the movable cavity 200 and sleeved on the sliding column 31, one end of the elastic member 4 abuts against the first end of the clip 3, and the other end of the elastic member 4 abuts against the end of the movable cavity 200. Wherein, the elastic member 4 exerts an acting force continuously pressing towards the inner side of the movable cavity 200 on the clip 3, when the clip 3 is pulled and the latch 30 is caused to be separated from the ratchet 100, the elastic member 4 is compressed and stored energy, until the external force pulling the clip 3 disappears, the elastic member 4 releases energy and enables the clip 3 to automatically reset so as to re-lock the ratchet bar 10.

Further, the sliding direction of the clip 3 is opposite to and perpendicular to the sliding direction of the ratchet strip 10. The arrangement makes the stress of the clamping piece 3 and the ratchet strip 10 more uniform, and effectively reduces the possibility of breakage of the clamping teeth 30 or the ratchet 100.

Further, in this embodiment, the clip member 3 is cylindrical, the first end of the clip member 3 is provided with a guiding protrusion 32, the clamping portion 20 is further provided with a guiding groove 202 communicated with the movable cavity 200, and the guiding protrusion 32 is slidably disposed in the guiding groove 202 to prevent the clip member 3 from rotating in the movable cavity 200. Of course, in another embodiment of the present invention, the clip member 3 may also be of a rectangular design, and in this case, it is not necessary to design a guide protrusion and a guide groove.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. Although embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the claims and their equivalents.
