Skin wound stiching instrument and stiching method thereof

Abstract

The invention discloses a skin wound suturing machine and a suturing method thereof. The suturing machine is formed by two substrates and each substrate of the suturing machine includes a rubberized fabric, a reinforcing rib and lock catches. The rubberized fabric is a ventilating soft material and the reinforcing rib is arranged along the length direction of the rubberized fabric. The rubberized fabric comprises an upper rubberized fabric layer, a lower rubberized fabric layer and a protection layer. The reinforcing rib is arranged between the upper rubberized fabric layer and the lower rubberized fabric layer. The reinforcing rib is provided with a ventilating hole and a plurality of lock catches with same intervals. The lock catch is L-shaped and consists of a locking strip and a lock bracket. The locking strip is provided with a lock gear and a clearance area. The lock bracket is provided with a lock plunger. The two substrates of the invention are connected mutually by penetrating the lock bracket of each other through the locking strip of each own so as to apply a force at two sides of the wound by simultaneously drawing the corresponding locking strip at two sides of the wound when suturing. The invention rotates one of the two substrates by 180 degrees according to a clockwise or anticlockwise direction and the structures of the two substrates are completely consistent and only one substrate is needed manufacturing during production. The invention has the advantages of novel structure, simple operation, convenient use and low manufacture cost.

Description

Background technique [0002] In the prior art, after the operation of the patient, the wound is sutured with thread, which not only consumes the energy of the doctor, but also increases the pain of the patient, leaving obvious scars for suturing; the new wireless suture technology has attracted wide attention in the medical field, and the Chinese patent ZL 03117364.0 discloses a "Skin Wound Locker". Its structure is two base belts, on which keyholes are respectively set, and a two-way or one-way ratchet is used to cooperate with the keyhole to lock the wound to achieve the purpose of locking ; The problem with this structure is: for the two-way spine, when pulling one end of the spine, a reaction force needs to be applied to the keyhole ...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, after the operation of the patient, the wound is sutured with thread, which not only consumes the energy of the doctor, but also increases the pain of the patient, leaving obvious scars for suturing; the new wireless suture technology has attracted wide attention in the medical field, and the Chinese patent ZL 03117364.0 discloses a "Skin Wound Locker". Its structure is two base belts, on which keyholes are respectively set, and a two-way or one-way ratchet is used to cooperate with the keyhole to lock the wound to achieve the purpose of locking ; The problem with this structure is: for the two-way spine, when pulling one end of the spine, a reaction force needs to be applied to the keyhole on the adhesive sticker at this end, and it is the same when pulling the other end of the spine. It is inconvenient to operate in the actual application process to achieve bidirectional force uniformity; while the one-way spines first have substrates with different positive and negative structures to be used together, which brings inconvenience to use; in addition, when pulling one end of the spines, it is necessary A reaction force is applied on the keyhole of the keyhole, and the action force and the reaction force are required to be equal in size and opposite in direction as much as possible. , another force is applied to the keyhole, and the shape of the object and the way of force are different. In actual operation, it will easily lead to excessive local extrusion of the lock near the wound, and it is even more difficult to achieve the equivalent and opposite of the two tensions. , balanced, complicated and difficult to operate

In addition, according to the structure in the Chinese patent ZL 03117364.0, there is no gap area in the spine so that the substrates on both sides cannot be completely close together. In clinical practice, it cannot ensure that the wound is exposed to the stapler, which may cause wound healing and dressing change. bring difficulties

Chinese patent ZL 2006 2 0012078.6 discloses an "adjustable seam-free suturing device", which is similar in structure to the above-mentioned patent, but there are also problems such as difficulty in realizing the equivalent, reverse, and balance of the two acting forces, and complex and difficult operations.
