Description
Technical field
The present invention relates to the medical instruments fields of wound repair, and especially a kind of medical instrument for skin expansion fills
It sets.
Background technique
In clinical position, the problem of orthopedist usually faces limb skin and soft tissue defects.By local dressing,
The means such as skin-grafting, local transfer flap, free flap transplantation are closed the surface of a wound, and the above method wants patient's microsurgical technique level
Ask higher, operation risk is relatively large, and often faces donor site cicatrization, the problems such as by area's anaesthesia, pigmentation.
Skin Deployment Technology theory, which refers to, has extensibility when skin is pulled by certain strength, be not necessarily to free skin the following group
In the case where knitting, edge of wound skin is pulled to center line by external force, distraction force is evenly spread on wound surrounding skin, benefit
The features such as with the intrinsic stretch characteristics of skin, stress relaxation characteristics, biological creep, mechanicalness creep, it is maximized to complete skin
Drawing, finally extends cutis laxa, the skin being pulled is extended, regenerated, and has achieved the purpose that closing wound.
Based on this technical know-how, clinically there are a variety of skin drawing and stretching devices, and finally development forms skin drawing and stretching art.
Existing skin dilator is locally directly pulled to skin edge, completes the expansion of skin, it is easy that this directly pulls method
Cause the tearing or necrosis of Pi Yuan.Expander crosses over defect of skin region, influences the dressing and wrapping of wound, easily causes infection.
The present invention discloses a kind of pair of reversed drawing skin dilator, using indirect drawing method, expansion drawing range, sufficiently excavation skin
Ductility, shorten patient's treatment cycle, reduce infection rate, and reduce patient suffering.
Summary of the invention
The present invention passes through double reversed pulling devices, so that symmetrically placed two arc wireropes generation is straightened close to each other
Trend produces a kind of double reversed traction forces.Wirerope is set in together with suturing anchor device, this double reversed traction force leads to again
Wirerope is crossed to act on two symmetrically placed suturing anchor devices.Suturing anchor device is again solid with the suture of the flap of wound two sides
It is scheduled on together.It in this way by double reversed indirect traction forces, evenly spreads on wound surrounding skin, realizes wound two sides skin
It is gradually expanded to center line, realizes that two flaps are slowly mutually drawn close, final closing wound.
Beneficial effects of the present invention
The present invention passes through double reversed pulling devices, and two symmetrically placed arc wireropes is made to generate to be straightened and close to each other become
Gesture produces a kind of double reversed traction forces.Wirerope is set in together with suturing anchor device, this double reversed traction force further through
Wirerope acts on two symmetrically placed suturing anchor devices.Suturing anchor device is sutured with the flap of wound two sides again and is fixed
Together.In this way by double reversed indirect traction forces, evenly spread on wound surrounding skin, realize wound two sides skin by
It gradually is expanded to center line, realizes that two flaps are slowly mutually drawn close, final closing wound.

Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the present invention is a kind of double reversed drawing skin dilators, comprising: double reversely to lead
Drawing device 1, suturing anchor device 2, wirerope 3, hook 4.Double reversed pulling devices 1, main part is a sleeve 11 and two
Screw rod 12,13, sleeve be hexagon hollow stud i.e.: outer-hexagonal, internal screw thread setting；First screw rod 12 and the second screw rod 13 are equipped with not
Equidirectional screw thread, i.e. the first screw rod 12 are equipped with left hand thread, and the second screw rod 13 is equipped with right-handed thread, and two screw rods pass through with sleeve
Matching thread connects together respectively.First screw rod 12 and 13 end of the second screw rod are equipped with vertical connecting rod 121,131, described
Connecting rod end is equipped with duct 122,132, and wirerope end can be inserted into duct, and tight by the first bolt 14 and the second bolt 15
Gu.Suturing anchor device 2 includes silica gel sheath 21 and silica gel piece 22, is set in together with wirerope 3, and silica gel sheath 21 is equipped with sewing hole
212, wirerope can be fixed on the skin around wound, silica gel sheath 21 is equipped with shackle 211, the hook 4 of different size
It is hooked on above.The silica gel piece 22 is the continuity of silica gel sheath 21, can be sutured on the skin by suture.The silica gel
Toughness of material is high, is not susceptible to elastic deformation, and not tearable.
The course of work of the invention
After selecting suitable anesthesia method, routine disinfection to spread list, defect of skin caused by wound need to remove edge of wound degeneration necrosis group
It knits, the surface of a wound carefully stops blooding, and first with the hands pushes edge of wound row Pinch test, after confirmation directly can not be closed the surface of a wound, installs double reversed
Pull the dilation therapy that skin dilator carries out skin.
Edge of wound length and wound defect area are measured first, select the wirerope 3 of appropriate length and sizeable suture solid
Determine device 2.Note: suturing anchor device 2 can suitably be trimmed with scissors.After the two is set with, along wound side, skin edge is put
It sets, suturing anchor device 2 is fixed on the skin around wound through on silica gel sheath 21 sewing hole 212 with suture 213.So
Silica gel piece 22 is done into appropriate trimming afterwards, makees to reinforce fixing on the skin with suture linear slit 221.
After the flap suture of completion wound side is fixed, the flap of the fixed other side is sutured with same method.
In wound diagonal angle, two sides wirerope comes together together respectively, ties up fixation respectively with wire loop 31.Two sides wirerope head
In the duct 122,132 of connection rod end on the double reversed pulling devices 1 of insertion, fastened with the first bolt 14 and the second bolt 15.
After being installed, the hollow stud sleeve 11 of double reversed pulling devices 1 is rotated, the first screw rod 12 and the second screw rod 13 prolong to both ends
It is long, double reversed traction forces are generated to wirerope 3, by the conduction of suturing anchor device 2, the flap of wound two sides is pulled indirectly
The trend mutually drawn close to center line occurs for power, to realize the slow expansion of skin.
After completing skin expansion, several pieces of sizeable hooks 4 are chosen, by it across wound, are hooked on the fixed dress of suture
On the circle hook 211 set, double reversed pulling devices are then removed.Before continuing drawing expansion skin next time, installation is double reversely to be led
Drawing device, reversed drawings first double to wirerope row, then remove hook.It operates repeatedly, the flap of wound two sides is slowly expanded, phase
It mutually draws close, is finally reached the purpose of closing wound.
