Description

Fingernail nail bed defects deck disappearance restoration and protection device

Technical field

This utility model relates to medical device; refer in particular to a kind of finger (toe) first nail bed defects deck disappearance restoration and protection device of fingernail technology, impaired nail matrix and the newborn smooth propagation in finger (toe) first deck and growth under protection nail body can be impelled.

Background technology

Deck is the important feature of finger tip, and have protection finger tip skin and support finger fatty tissue, strengthening refers to the effect that abdomen is felt, and assisted gripping, scratched, the specific function such as bullet pulls out.The defect on deck, not only destroy the attractive in appearance and complete of finger, also make finger tip lose stable holding and pinch function, the onychostroma of nail matrix and the complete of first template are depended in the tissue repair after nail matrix damage and the good growth on deck, therefore nail bed defects should be repaired perfect as far as possible.Traumatic nail bed defects Primary repair is the crux obtaining good efficacy, and second phase process increases difficulty, poor effect.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art; a kind of structure is simple, easy to operate, therapeutic effect is good finger (toe) first nail bed defects deck disappearance restoration and protection device is provided, impaired nail matrix and the newborn smooth propagation in finger (toe) first deck and growth under protection nail body can be impelled.

For achieving the above object, technical scheme provided by the utility model is: fingernail nail bed defects deck disappearance restoration and protection device, it includes nail body, nail body surface is curved, its radian matches with the radian of two fingernail or two toenails, nail body front end is arc, and its radian matches with two finger fingertips or two toe finger tips; Nail body surface is provided with several open-works run through up and down.

Described open-work is square, circular, oval, triangle or polygon.

Described nail body adopts the material such as medical silica-gel or medical resin to make molding.

Described nail body is multiple, and its shape matches with two corresponding fingernail or two toenails respectively.

Described nail body four diagonal positions are provided with fixing hole.

Operation method of the present utility model and deck cover free tomography nail matrix and repair therapeutic outcome no significant difference compared with nail bed defects, have again following advantage with covering without deck to use instead compared with traditional method that kpetrolatum gauze directly wraps up nail matrix wound surface:

(1) nail body covers compressing nail matrix, can make impaired nail matrix and newborn deck smooth propagation and growth under the protection of deck substitute (nail body).

(2) because the pain that the adhesion of nail matrix wound surface causes directly wrapped up by kpetrolatum gauze when avoiding traditional approach to change dressings, and sew up and closely do not cause free nail matrix of sewing up by kpetrolatum gauze avulsion.

(3) avoid wound that modes such as adopting cripetura phalanges causes and refer to profile, changing function affect attractive in appearance, and the nail growth obstacle that causes of nail bed defects or serious first deformity.

(4) nail matrix after traditional approach reparation without the protection on newborn deck, easily again damages between healing stage, deck or the protection of deck substitute (nail body) suture in situ is avoided the generation of this type of thing.

This law is applicable to deck disappearance, and nail bed defects district is less than the case of hindering lactulum unguis 50%.Hinder lactulum unguis 50% as nail bed defects district is greater than, desirable big toe dissociate tomography nail matrix lobe transplant cover, as wound fingernail complete, after can directly cleaning punching with method cover hinder lactulum unguis.Clinical practice proves: the nail body that the material such as deck or medical silica-gel makes covers the Therapeutic Method that free tomography nail matrix repairs nail bed defects, all meet nail matrix and deck to grow and repair rule, operation method is simple, operating time is short, drain congestion is unobstructed, decrease postoperative infection chance, improve postoperative deck recovery effects.Worth situation of all-level hospitals is extensively promoted.

Accompanying drawing explanation

Detailed description of the invention

Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1, finger (toe) first nail bed defects deck disappearance restoration and protection device described in the present embodiment includes nail body 1, nail body 1 adopts the material such as medical silica-gel or medical resin to make molding, nail body 1 surface is curved, its radian matches with the radian of two fingernail or two toenails, and nail body 1 front end is arc, and its radian matches with two finger fingertips or two toe finger tips; Nail body 1 surface is provided with several open-works 2 run through up and down, and open-work 2 is square, circular, oval, triangle or polygon.During production, nail body 1 is multiple, and its shape matches with two corresponding fingernail or two toenails respectively.If needed, fixing hole can also be provided with at nail body 1 four diagonal positions, be convenient to fix.

The operation method of above-mentioned nail body is: first trouble is referred to conventional cleaning, sterile drape, adopt and refer to root infiltration anesthesia, refer to that root rubber compression cord stops blooding, strict debridement.Complete for impaired deck starting is pulled out (noting protection germinal matrix); with Kirschner wire fixation fracture end after the person's debridement that there is Phalangeal fracture; prune nail matrix edge of wound; nail bed defects wound surface is made to be similar to regular quadrilateral, rectangle or triangle wound surface; prohibit sth. made by twisting and pinch nail matrix; retain periosteum above phalanges as far as possible, as periosteum disappearance, then portray matsurface so that nail matrix better adheres to survival with scalpel on phalanges surface.Double-layer safety blade or general surgery blade drive in the wrong direction cut residual nail matrix smooth in thick nail matrix lobe (thickness is no more than normal nail matrix 50%), be covered in nail bed defects district, the scope that cuts is avoided first quarter moon as far as possible and is made sure to keep in mind.Also after the nail matrix of avulsion (grinding stranding severe patient to abandon) can being pruned cleaning, suture in situ lacks district to nail matrix.Adopt 2.5mm ~ 3mm interval needle gage, 5-0 admires silk thread or 3-0 line rotator cuff suturing with thread management nail matrix, and make every effort to soft during stitching, avoid overtension, operations all follows noinvasive principle, in order to avoid reproduce into laceration in sewing process.As distal phalanx exposes a little, give suitably stinging and remove.Selecting the materials such as medical silica-gel to make the nail body of size corresponding to hindering nail plate as deck substitute, fixing corner in nail matrix edge skin with 1-0 suturing with thread management.Use Petroleum gauze pressure dressing after sewing up, pressure is moderate.

Postoperative care: postoperative Conventional antibiotic prevention infection 1 ~ 2d, continue heat lamp and irradiate or infrared physiotherapy, lifting affected limb eliminates swelling.Postoperative 2d more change dressings, note when changing dressings keeping without hematocele under nail body, nail body conduction hole is unobstructed, and after 2 weeks, suture on the substitutes of deck is fixed in dismounting.

Clinical effectiveness: adopt said method to treat 10 example 11 lactulum unguis defect deck disappearance wound repairinies and take out stitches at 14 ~ 16d, 2 point out that existing nail margin is dark-coloured, recover gradually after changing dressings, all the other all survive well, Follow-up After 6 ~ 12 months, curative effect is with reference to deck regeneration criterions of therapeutical effect such as Li Baoshan: outstanding 3 refer to, good 5 refer to, general 2 refer to, poor 1 refers to.Repair deck, the equal well-grown of nail matrix, wound refers to Fingertip feeling and the ability that grips recovers good, and it is obviously lopsided that nail matrix grows smooth nothing, obtains expected effect.
