Medical stitching pulling buckle

Abstract

The invention discloses a medical stitching pulling buckle. The medical stitching pulling buckle comprises two substrates which are respectively adhered to the two sides of a skin wound and adopt the same structures; a pulling strip, a locking buckle and a bonding layer are arranged on each substrate, wherein each bonding layer is adhered to the bottom of the corresponding locking buckle, each locking buckle is arranged at the head of the corresponding pulling strip, and a downwards-inclined concave area is arranged on the side, facing the corresponding pulling strip, of each locking buckle. During use, the two substrates are adhered to the two sides of the wound through the bonding layers, the pulling strips of the substrates penetrates the locking buckles thereof mutually, and pulling forces are applied at the same time to lock the two substrates, so that the skin wound adhered to the lower parts of the substrates is stitched. As the two substrates adopt the same structures, and the forces applied to the two sides are equal, the stresses on the two sides of the skin wound are balanced; meanwhile, through the concave areas on the outer sides of the locking buckles, a gap area is formed between the contact surfaces of the two locking buckles, so that the wound below the locking buckles is prevented from being covered. According to the size of the wound, an appropriate number of the medical stitching pulling buckles provided by the invention are operated sequentially according to the steps, so that the wound stitching for a patient can be completed.

Description

Technical field [0001] The invention relates to a medical appliance applied to skin wounds, in particular to a medical suture pull buckle. Background technique [0002] In the prior art, stitches are usually used to suture patients' wounds after surgery. This method will leave obvious scars after the wound has healed, and will cause secondary trauma during stitch removal, which will increase the patient's pain. The new wireless suture technology has attracted wide attention from the medical community. Chinese patent CN03117364.0 discloses a "skin wound locker". Its structure is two base bands with keyholes set on them, using a two-way or The unidirectional ratchet is matched with the lock hole to lock the wound and achieve the purpose of locking; the problem with this structure is: for the two-way ratchet, when one end of the ratchet is pulled, the lock hole needs to be glued on that end Applying a reaction force, it is difficult to achieve uniform force in both directions, and ...

[0002] In the prior art, sutures are usually used to suture patients' wounds after surgery. This method will leave obvious scars after the wound heals, and will cause secondary trauma during the stitch removal process, which will increase the pain of the patient.

The new wireless suturing technology has attracted wide attention in the medical field. Chinese patent CN03117364.0 discloses a "skin wound locker". The one-way ratchet and the keyhole cooperate to lock the wound to achieve the purpose of locking; the problem with this structure is: for the two-way ratchet, when one end of the ratchet is pulled, the lockhole that needs to be glued on this end Apply a reaction force, so it is difficult to achieve uniform force in two directions, and it is inconvenient to operate in the actual application process; while the one-way spines first have positive and negative substrates with different structures to be used together, which brings inconvenience to use; in addition, when pulling At one end of the spine, it is necessary to apply a reaction force on the keyhole corresponding to the base belt, and the action force and the reaction force are required to be as equal in size and opposite in direction as possible, acting on the two base belts and applying them in a balanced manner in the direction of wound closure. Due to the fact that one force is applied to the spine and the other 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, making it more difficult to achieve The two pulling forces are equivalent, opposite, and balanced, and the operation is complicated and difficult

In addition, according to the structure in the Chinese patent CN03117364.0, 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 hinder wound healing and replacement. medicine makes it difficult
