Description
Technical field
The present invention relates to a kind of soft tissue external fixing rack, belong to soft tissue technique for fixing field.
Background technology
The method for the treatment of large area skin wounds has a variety of such as the healing of skin grafting, local skin flap's transplantation, Tissne expousd, free flap art and secondary at present.Some of which method is attended by higher pathogenicity rate and method is complicated, risk is higher, treatment cycle is long；Above-mentioned methods for the treatment of is the most expensive but also affect attractive in appearance compared with PC's surface of a wound.
The mechanical performance of soft tissue has been done numerous studies by present stage.Tension force is the main power that skin bears, if amplitude and waveform are suitable, tension force contributes to growth and the expansion of the surface of a wound in early days.Extracellular matrix and the [amorphous of scalable connective tissue (such as skin, blood vessel, manadesma) are contained within collagenous fibres, elastomer, and it is affected by mechanical force.Changes in biomechanical properties of pig skin especially mechanical creep and stress relaxation ability make skin can obtain overlength elongation at short notice.After so-called mechanical creep i.e. power effect a period of time, skin can stretch elongation.Stress relaxation can cause skin expansion to certain distance, and skin tension is gradually reduced.
Stretching skin promotes that the principle of surface of a wound PC has been widely used for treating various skin injury, to assist wound healing.But sometimes with complication and overtension situation easily occurs in wound.In order to solve these problems, have employed different methods such as Distraction Apparatus or tissue expander clinically.The previously design of Skin stretching device can cause the huge incidence of disease.Because they are rigid in essence, unknowable local organization tension force can be produced, frequently result in the necrosis of surface of a wound edge tissue, damage or tear.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of soft tissue external fixing rack.
The present invention solves its technical problem and is adopted the technical scheme that:
This soft tissue external fixing rack, its structure includes: handwheel, spring, slide block, screw mandrel, guide rod, crochet hook can kirschner pinhocks；Its architectural feature is: described slide block is provided with two, described right side slide block is provided with the screwed hole matched with screw mandrel, left slider is provided with the manhole accommodating screw mandrel, wherein described slide block and the described screw mandrel in left side is run through by through hole and is connected, the described slide block on right side is fixed in one end of described screw mandrel with described screw mandrel after being connected via screwed hole, described screw mandrel top is provided with handwheel described in, a described spring being sleeved on described screw mandrel it is provided with between described handwheel and left slider, described slide block medial surface is provided with multiple pin hole, described slide block upright position is provided with kirschner pinhock, described crochet hook shape is all in hook-type.
Described screw mandrel specifically uses pressurization screw mandrel.
Described crochet hook specifically uses stainless steel or titanium alloy material to make.
Distance between described slide block lateral surface is less than the length of described screw mandrel, and described screw mandrel length is less than the length of described guide rod.
Described shoe surface is oxidation-treated.
Described spring specifically uses 304H stainless steel spring silk to make, described spring surface Passivation Treatment.
Compared with prior art, the present invention has the beneficial effect that:
Soft tissue external fixing rack the most of the present invention is either used in preoperative art or the postoperative tension force that can reduce surface of a wound edge, in use without any obvious complication and side effect.
Soft tissue external fixing rack the most of the present invention treats large-area skin or skin tissue defects by loosening skin or hypodermis, thus avoids skin graft and skin flap grafting transposition of skin flap, postoperative skin drawing and stretching closer can be used under low tension to beautify the surface of a wound.
3. the present invention can unidirectional pressurize, elastic pressurized, and double-rod guides, and various threads a needle, and reaches surface of a wound Guan Bi with less tension force, reduces surface of a wound damage.
4. when the present invention sews up, the Impact direction of skin is flexible, fixed form is various both can use that hook method is fixing be may be used without Kirschner wire mattress suture method and fix, by the most multidirectional stretching skin closure surface of a wound of flexibility about spring, it is to avoid produce unknowable local organization stress and the necrosis of surface of a wound edge tissues, damage or tear.
Accompanying drawing explanation
Fig. 1 is plan structure figure of the present invention.
Fig. 2 is that the present invention faces structure chart.
In figure: 1 handwheel, 2 springs, 3 slide blocks, 4 screw mandrels, 5 guide rods, 6 crochet hooks, 7 kirschner pinhocks.
Detailed description of the invention
As shown in Figure 1, 2: a kind of soft tissue external fixing rack, structure includes: handwheel 1, spring 2, slide block 3, screw mandrel 4, guide rod 5, crochet hook 6 and kirschner pinhock 7；nullIts architectural feature is: described slide block 3 is provided with two，Described right side slide block 3 is provided with the screwed hole matched with screw mandrel 4，Left slider 3 is provided with the manhole accommodating screw mandrel 4，Wherein left slider 3 and described screw mandrel 4 are run through by through hole and are connected，Right side slide block 3 is fixed in one end of described screw mandrel 4 with described screw mandrel 4 after being connected via screwed hole，Described screw mandrel 4 top is provided with handwheel 1 described in，A described spring 2 being sleeved on described screw mandrel 4 it is provided with between described handwheel 1 and left slider 3，Described slide block 3 medial surface is provided with multiple pin hole，Described slide block 3 upright position is provided with kirschner pinhock 7，Described crochet hook 6 shape is all in hook-type，Screw mandrel 4 specifically uses pressurization screw mandrel，Crochet hook 6 specifically uses stainless steel material to make，Distance between two slide blocks 3 is less than the length of screw mandrel 4，Screw mandrel 4 length is less than the length of guide rod 5，Slide block 3 surface is through preservative treatment of spraying paint，Color as required depending on，Spring 2 specifically uses 304H stainless steel spring silk to make，At spring 2 plating zinc on surface post-passivation.
