Abstract
Provided is a medical regulation type wound suturing device. The medical regulation type wound suturing device comprises a first fixing block and a second fixing block, wherein the first fixing block and the second fixing block are arranged on the skin on the two sides of a wound. Suturing holes are formed in the first fixing block and the second fixing block respectively, a pull line is arranged on the first fixing block, the pull line is a medical line for operation, the second fixing block is of a hollow structure, a spring is arranged in the second fixing block, one end of the spring is connected with the second fixing block, the other end of the spring is connected with a push rod, a hole is formed in the push rod, pull line holes are formed in a pair of symmetrical side faces of the second fixing block, and the pull line is led in through the pull line holes in one side of the second fixing block in a threading mode, passes through the hole in the push rod and then is led out through the pull line holes in the other side of the second fixing block in a threading mode. According to the medical regulation type wound suturing device, the movable medial pull line for operation is used for continuously closing the edges of the wound in a drawing mode, and the round is made to be closed gradually. Every day, a doctor appropriately regulates the tension degree of the pull line according to the tissue swelling degree of a patient, if the tension is too high, the pull line is loosened; if the tension is reduced, the pull line is tensioned, and therefore the defect that in traditional relaxation suture or steel wire suture, the situation that only tensioning can be conducted, but loosening cannot be conducted is avoided.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of for relaxation incision, be difficult to the regulation type wound stiching instrument of the larger wound of tension force or the damaged wound of larger area skin histology of primary closure.
Background technology
Clinical when processing " relaxation incision ", " limb swelling otch ", " skin, tissue defect otch ", " the larger otch of tension force ", the degree of tightness of sewing up is very crucial, sew up tension, can impact organize blood supply, sewed up pine, deep tissue exposes and can not cover, and Chang Yi causes the early complications such as infection.During at present early time treatment because tension force is large, clinical normal employing tension suture method, but along with disappearing of swelling, the healing of wound, the tension force of wound reduces, and later stage skin injury needs again again the second stage of, even more phases stitchings of three phases, in the time of can not flap coverage, need surgery skin grafting, Vessel Skin Flap with wound closing face.So just not only to the wounded, bring secondary injury and misery even repeatedly, and often after tissue edema disappears, relaxation incision skin and subcutaneous tissue are combined closely, wound surface can not be drawn stitching over to one's side, need to adopt skin-grafting or flap operation flap coverage, the cicatrix of wound healing also clearly, increases working doctor amount, causes the increase that repeats injury and medical treatment cost.The method of tension suture adopts " 8 " word or mattress suture method often, adds with medical latex tube and avoided the compressing of excessive thread tension to local skin between suture and skin, causes skin ischemic necrosis, or suture slits de-.
Summary of the invention
Technical problem to be solved by this invention is for solving shortcoming in can not primary closure myometrial suture process compared with greatly of relaxation incision, tension force in prior art, to provide a kind of to reduce wound healing time and reduce the Medical adjustable wound stitching instrument that wound scar forms, the wounded's who tears for relaxation incision or wound surface and large area skin healing has alleviated misery, reduce operation number of times, Economy type medicine cost.
For solving technical problem of the present invention, adopt following technical scheme:
A kind of Medical adjustable wound stitching instrument, comprise the first fixed block and the second fixed block that are arranged on the skin of wound both sides, on described the first fixed block and the second fixed block, be equipped with sewing hole, on described the first fixed block, bracing wire is set, described bracing wire is the medical line of operation, described the second fixed block is hollow structure, a spring is established in the inside of described the second fixed block, described spring one end connects the second fixed block, the other end of described spring connects a push rod, on described push rod, hole is set, on described the second symmetrical side of fixed block one, be equipped with bracing wire hole, after penetrating, the bracing wire hole of described bracing wire by the second fixed block one side by the bracing wire hole of the second fixed block opposite side, pass again by the hole on push rod.
Described the first fixed block arranges two line holes, described line arranges bracing wire on hole, a spring is established in the inside of described the second fixed block, the two ends of described spring arrange push rod, on described two push rods, be equipped with hole, on described the second symmetrical side of fixed block one, be equipped with two bracing wire holes, after the bracing wire hole of described every bracing wire by the second fixed block one side penetrates, by the hole on push rod, by the bracing wire hole of the second fixed block opposite side, pass again.
Described the second fixed block inside arranges block, and described push rod and spring link arrange bead, and the first block is set on described push rod, and described block is arranged between bead and the first block, and described block and bead and the first block are adaptive.
On described the second fixed block, anchorage shoe is set.
Described bracing wire is the medical line of the operation of nonabsorable.
Described the first fixed block and the second fixed block be equipped with glue with wound skin contact.
The present invention adopts the medical bracing wire of mobilizable operation constantly to draw edge of wound over to one's side, makes wound closed gradually.Doctor suitably adjusts bracing wire tensity according to patient tissue swelling degree every day, and tension force is too high, unclamps bracing wire, and bracing wire is strained in hypotension.The defect that having avoided traditional tension suture or steel wire to sew up can only be tightly, can not pine, when drawing involutory edge of wound over to one's side, also avoided simultaneously traditional method every spend 2-3 days could tight shortcoming once, apply the present invention, can loosen, tighten at any time.Apply in addition the present invention, also can carry out degree of tightness according to patient's tolerance degree, do not need anesthesia, avoided traditional sewing method to sew up under narcotism, after anesthesia is disappeared, because overtension causes the not tolerant situation of patient's pain.Utilize the present invention, can not cause because of the suture operation of many phases the frightened obstacle syndrome of corrective surgery, for the later stage also need to pave the way in the sufferer of processing.Medical worker is in using process of the present invention, and workload is equivalent to routine changes dressings, and a people is free-hand just can be operated, and does not increase workload, also unlike traditional treatment, all needs to be equivalent to debridement and suturing at every turn, increases medical treatment cost.Application the present invention, most relaxation incisions all can primary healing, without second phase skin-grafting, flap, processes, and shortens the hospital stays, saves social cost.
