Description
Technical field
The present invention relates to a kind of medicine equipment, and in particular to a kind of device for closing skin wound.
Background technology
Skin wounds, such as the wound of wound or surgical site infections are handled, traditional mode is closed using medical needle linear slit.
But needlework are sewed with many defects, additional pin hole wound is such as caused, suture easily causes foreign body rejection, can stayed at Wound healing
Under ugly scar.
Existing technology such as US3926193, CN1524507A, CN103690207A, CN104755033A provide some can
The selective technical scheme for solving these problems.For relatively regular straight line wound, these technical schemes can be well
Reply, also have to not very regular curve wound and consider to some extent.For the wound of joint part, such as knee and ancon,
Local skin is inevitably generated large range of flexible during due to limb activity, and the adaptability of Wound closing device is proposed
Challenge.CN104755033A forms with closing assembly snakelike by elastic base plate, by axial support or power distribution mechanism
Arrangement largely solves response of the Wound closing device to wound skin longitudinal extension, and adapts to curved shape
Wound.But its is snakelike be arranged in response wound skin longitudinal extension during, the skin dilatation of wound both sides is not right
Claim and uneven.At Wound healing initial stage, this uneven and asymmetric shearing force for being likely to form edge of wound longitudinal direction or even vertical
To relative shift, so as to influence Wound healing and cause local pain.
The content of the invention
The present invention provides some otherwise varied solutions, its emphasis for the weak point of above-mentioned prior art
It is to improve the mode that closing device applies wound skin active force so that active force is more uniformly reasonably distributed, and
The symmetry of active force is remained closed during wound skin longitudinal extension.Further improve then is embodied in wound closure dress
Put response wound skin longitudinal extension during compensation as caused by edge of wound skin deformation closure function power reduce trend.
The opportunity that this Wound closing device uses has been completed for operation in vivo, hypodermis and following anatomical layer
Wound closed, or the natively shallow wound of comparison sheet, be only used for closing skin layer.
Concrete technical scheme is：
A kind of Wound closing device, including can respectively with skin firm attachment near edge of wound both sides two basic change piece,
It is divided into the first bonding pad and the second bonding pad, at least one closing assembly for adjusting edge of wound distance or clossing pressure.With reference to
The primary structure of piece be by can not significantly stretch can only flexural deformation sheet stent knot made of there is the material of certain flexibility
Structure, closing assembly are directly fixedly connected with the first bonding pad and the second bonding pad respectively.
This structure needs to meet following functions requirement：
1) wound when edge and the telescopic variation of wound vertical direction occurs because limbs posture changes for skin near wound
Closing device can make skin at edge of wound avoid that telescopic variation occurs.
2) the first knot when edge and the telescopic variation of wound parallel direction occurs because limbs posture changes for skin near wound
Close piece and the second bonding pad with can making its both sides edge of wound skin uniformity covered sync response telescopic variation.
Here " edge of wound " refers to the both sides of the edge of scalpel edge or wound breakage mouth.
Here it is " edge of wound distance " " to adjust edge of wound distance or clossing pressure " specifically when the preceding adjustment of wound closure, works as wound
What is then adjusted after mouth closure is the pressure between " clossing pressure " i.e. both sides wound margin tissues.
Here " can not significantly stretch can only flexural deformation have it is certain flexible " concrete meaning be in the applied field
In the normal reasonable scope of scape, when bonding pad and human skin tissue are accordingly to be regarded as into elastomer, the bullet of bonding pad manufacture material
Property modulus be noticeably greater than skin histology, for example more than ten times, i.e., both by equivalence active force when with reference to sheet material shape
Variable can be ignored relative to the deformation quantity of skin histology.But because bonding pad is flake structure, with regard to the mechanics of its structure
It is easily deformable when being bent power by lateral folding and irreplaceable flexibility can be shown for characteristic.
Herein to relative orientations arc, direction is adjectival is especially defined as follows：Regulation is specific " with wound parallel direction "
Implication is that wound is considered as into straight line wound, and wound skin is considered as to the plane of zero thickness, then the skin junction after wound closure
It is considered as one " straightway "." with wound parallel direction ", direction i.e. parallel with the straightway, also can be described as " longitudinal direction ".
Direction parallel with skin plane and vertical with the straightway is that can also be described as " transverse direction " " with wound vertical direction ".With skin
Skin plane is vertical and the direction of sensing inside of human body is " lower section " or " following ", otherwise is " top " or " above ".Near wound
Its " nearside " is called in the position of relatively close wound, otherwise " distal side " of meaning.Point to and be interpreted as approximation side in above all of direction
To.
It can realize that the sheet-scaffolds constructs of above-mentioned function can be with specifically, the first bonding pad and the second bonding pad have edge
The zigzag sheet-scaffolds constructs of wound parallel direction extension, referred to as zig zag stent.Being scribbled below zig zag stent can
The adhesive combined closely with skin and conveniently freed when no longer needing, this kind of adhesive is in conventional Wound closing device
There is application more.The both ends of closing assembly for adjusting edge of wound distance or clossing pressure are combined with the first bonding pad and second respectively
Piece is fixedly connected.It is preferred that be fixedly connected with the summit of zig zag stent both sides, it is further preferably close with zig zag stent structure
The adjacent proximal vertex of wound side is fixedly connected.The flexible function of changing of local skin is adapted in order to improve, without influenceing to close
The uniformity and stability for the closing force that component applies to edge of wound skin, the first bonding pad and the second bonding pad can use hardness
The slightly higher weaker material of telescopic action.As compensation, set in the turning point of zig zag stent thickness increase and what width reduced
Notch features.
In order that obtaining the uniformity for the closing force that closing assembly applies to edge of wound skin further improves, can be in zigzag
The rhombus that the long axis direction of perforate is vertical with wound bearing of trend and is connected with zig zag stent is set in the middle neutral of support
The fine-structure mesh of mesh.
Zig zag stent and the fine-structure mesh of diamond-shaped meshes can use conventional medical plastic once compressing, and can be made
Continuous banding, appropriate length is cut into as needed.
Selectively, the primary structure of the first described bonding pad and the second bonding pad is it can also be provided that parallel along wound
The continuous rhombus sheet-scaffolds constructs of direction extension, referred to as diamond rack, the major axis of rhombus are vertical with wound bearing of trend.For
The notch features for improving zig zag stent extensional performance are also applied at crosspoint and the turning point of diamond rack structure.
Selectively, three kinds of modes are appointed below described sheet-scaffolds constructs, in above, middle neutral or more
The elastic film that meaning combination settings are connected with sheet-scaffolds constructs.The effect of elastic film and the effect phase of diamond-shaped meshes fine-structure mesh
Seemingly, preferably using the high molecule micropore film of good air permeability.
When wound is located at joint part such as knee or ancon, the deformation bent and skin may be caused to be up to 50% is stretched in joint.
The longitudinal stretching of skin near edge of wound, the horizontal compensatory contraction of skin can be caused, this can cause the wound closed just originally
The clossing pressure of edge skin, which reduces, even to ftracture.In this case, present invention employs following technical scheme to be tackled：
A kind of Wound closing device, including can respectively with skin firm attachment near edge of wound both sides two basic change piece,
It is divided into the first bonding pad and the second bonding pad, at least a set of closing assembly for adjusting edge of wound distance or clossing pressure.With reference to
The primary structure of piece be by can not significantly stretch can only flexural deformation sheet stent knot made of there is the material of certain flexibility
Structure.First bonding pad and the second bonding pad are separate with closing assembly, and closing assembly is by flexible connecting member respectively with
One bonding pad and the second bonding pad are fixedly connected indirectly.
This structure needs to meet following functions requirement：
Wound closes when edge and the telescopic variation of wound vertical direction occur because limbs posture changes for skin near wound
Device can make skin at edge of wound avoid that telescopic variation occurs.
Skin occurs to be combined along with during the telescopic variation of wound parallel direction first because limbs posture changes near wound
Piece and the second bonding pad with can making both sides edge of wound skin uniformity sync response telescopic variation, and the closure of edge of wound skin
Significant changes do not occur for active force.
The concrete meaning of " uniformity sync response " here be skin histology receive power it is flexible when bonding pad and institute
Attachment skin histology substantially synchronously deform and it is non-significant prevent its deform.The implication of " uniformity " focuses on emphasizing thin slice branch
Frame structure it is continuous consistent.Due to the difference of bonding pad and the mechanical characteristic of skin histology, " uniform ", " consistent " and " synchronization " exists
It is necessarily relative in theory.
Here " significant changes do not occur " can also be expressed as " generally remaining constant size ".
The first bonding pad and the second bonding pad can use in the technical scheme is combined with foregoing first bonding pad and second
The technical scheme identical technical characteristic that piece is fixedly connected with closing assembly, it is specially：
The primary structure of first bonding pad and the second bonding pad is the zig zag stent extended along wound parallel direction.
In the middle neutral of zig zag stent set mesh long axis direction it is vertical with wound direction simultaneously and zig zag stent
The diamond-shaped meshes fine-structure mesh of connection.
The primary structure of first bonding pad and the second bonding pad is the continuous diamond rack knot extended along wound parallel direction
Structure, the major axis of rhombus are vertical with wound bearing of trend.
Below sheet-scaffolds constructs, in above, middle neutral or more any combination of three kinds of modes set with it is thin
The elastic film of plate rack structure connection.
Closing assembly in the technical scheme of above-mentioned two series can use the tune commonly used in existing Wound closing device
Section mode, such as frenulum, VELCRO adhesive tape, pull bar, pulling buckle, bracing wire, it is preferential using by screw rod, internal threaded base and through hole base
Seat composition screw thread adjusting means.
Make, each closing assembly and the drag-line of both sides can be passed through as a set of component, drag-line for the ease of shaping
Chimeric deck is realized to be fixedly connected with the first bonding pad and the second bonding pad.
When wound is located at limbs flexing side , such as popliteal nest, throat, belly etc., the flexing of limbs can cause closing assembly
Wound skin is left, and causes edge of wound skin closure active force to reduce.
Solve this problem, can be in the internal threaded base and through hole pedestal of spiral closing assembly and below the pedestal
Zig zag stent structure or diamond rack structure and proximal vertex between set allow between pedestal and supporting structure with skin
The parallel plane interior edge of skin is slided with wound vertical direction and limits the part of the above two in the phase on skin plane direction
The pair that is slidably connected mutually departed from.
The technical essential of sheet-scaffolds constructs is that the arm for forming support will have certain rigidity so that support is put down by direction
Row arm shape when the active force of own layer itself does not significantly change.And the junction between arm will have enough soft
Property so that the structural relation between arm can respond the active force for being oriented parallel to supporting structure plane and change.Support
Flexibility realized by " thin slice " structure of support, be mainly used in responding skin histology perpendicular to upward curved of side skin surface
Song deformation.Generally speaking, sheet-scaffolds constructs are mainly by the mechanical structure of itself, rather than are realized mainly by the characteristic of material
Respectively to different force-responsive characteristics.These principles are followed, except using in addition to above structure, technology that also much can be flexible
Scheme, all it is common technical knowledge for the those skilled in the art of mechanical design field.
The advantages of this structure, is that the mechanical characteristic requirement of the material to manufacturing the device greatly reduces, and is designed so as to allow
Scheme has more selections in face of the biological characteristics and material cost of material, improves properties of product, reduces product cost, makes
Obtaining production technology can also greatly simplify.
