The guide pillar is adjusted via the hollow eccentric adjusting screw to deviate from the position of a circle center, so that the purpose of cutting cellulocutaneous flaps from thin to thick smoothly and from thick to thin gradually or cutting cellulocutaneous flaps or corium tissue flaps with equal thicknesses is achieved, and the problems that an existing cellulocutaneous flap cutting machine only can cut large pieces of cellulocutaneous flaps with equal thicknesses, cannot cut cellulocutaneous flaps from thin to thick gradually smoothly, and either cannot cut corium tissue flaps from thin to thick gradually smoothly are resolved.
Description
One, technical field
This utility model relates to the medical surgical operating theater instruments, is specifically related to a kind of centering type skin graft and cuts machine.
Two, background technology
In skin graft transplant operation process, need cut sometimes from thin and be smoothly transitted into thick skin graft or dermal tissue sheet gradually, improve surgical effect; In addition, in order to study skin trauma regeneration and scar healing, need make from shallow being smoothly transitted into dark skin and excising wound at toys such as rabbit and rats, as study model.
Employed in the past dermatome mainly contains roller type dermatome, electric dermatome and drum dermatome.Like number of patent application is 201110095745.7, and name is called the patent of " a kind of electric dermatome mechanical driving device ", through in dermatome, adding mechanical driving device, thereby has realized electronic bark fetching; And for example number of patent application is 92224345.X, and name is called the patent of " negative pressure automatic cutisector ", through in dermatome, adding negative pressure control apparatus, not only can reduce skin graft shrinkage and extra wound, and realize automatic bark fetching.But no matter be manual or automatic (electronic) dermatome, can only cut the large stretch of skin graft of uniform thickness, can't cut from thin and be smoothly transitted into thick skin graft gradually, also can't cut from approaching and be smoothly transitted into thick dermal tissue sheet gradually.
Three, summary of the invention
The problem that the object of the invention exists to existing dermatome just; Provide a kind of novel eccentric formula skin graft to cut machine; This centering type skin graft machine of cutting can be used for cutting from thin thick skin graft or the dermal tissue sheet of being smoothly transitted into gradually; Can only cut large stretch of uniform thickness skin graft thereby overcome existing dermatome, can't cut from thin and be smoothly transitted into thick skin graft gradually, also can't cut from approaching the thick problems such as dermal tissue sheet that are smoothly transitted into gradually.
The present invention realizes through following technical scheme:
Like Fig. 1, shown in Figure 2; The centering type skin graft cuts machine; Comprise: circular arc drum face 1, toolframe 2, guide pillar 3, toolframe handle 4, toolframe are regulated hold-down nut 5, hollow eccentric adjusting screw 6 and are cut cleaner handgrip 7, and toolframe 2 is made up of blade retainer 21, toolframe bogie side frame 22 and adjustment hole 23.
Guide pillar 3 runs through the orbit hole 13 and adjustment hole 23 of 12 both sides, circular arc side, and there is external screw thread at guide pillar 3 two ends, and toolframe is regulated hold-down nut 5 and is fastenedly connected with guide pillar 3 two ends, and toolframe 2 is fixedly connected with guide pillar 3; Toolframe handle 4 is fixed on the bogie side frame 22 of toolframe.
Hollow eccentric adjusting screw 6 inner surfacies are smooth, are made up of spiral shell head 61, hollow bolt 62, nut 63 and screw 64, and spiral shell head 61 is positioned at hollow bolt 62 1 ends, and hollow bolt 62 other ends are provided with external screw thread, and nut 63 is fastenedly connected through female thread and hollow bolt 62; The orbit hole 13 that hollow bolt 62 runs through 12 both sides, circular arc side engages circular arc drum face 1 through nut 63 and spiral shell head 61, and guide pillar 3 passes hollow eccentric adjusting screw 6 simultaneously, and the screw 64 that cuts on cleaner handgrip 7 and the hollow bolt 62 is fastenedly connected.
Wherein, oval or rectangle adjustment hole 23 both sides indicate scale on the toolframe bogie side frame 22, and scale range be " 0mm is to 4mm ", and near blade retainer 21 1 sides, and the distance of blade and arc surface 11 is 0 to " 0mm " scale at this moment at adjustment hole 23.Guide pillar 3 can and use toolframe to regulate hold-down nut 5 and fix along 23 slips of the adjustment hole on the toolframe bogie side frame 22, thereby change blade and circular arc rouse the distance of cambered surface on the face, reach the purpose that cuts the equal thickness skin graft.Because toolframe bogie side frame 22 is marked with scale, so can accurately control the distance of cambered surface on blade and the circular arc drum face.
As shown in Figures 2 and 3, about promote hollow eccentric adjusting screw 6 and guide pillar 3, and circular arc drum face 1 is fastened between spiral shell head 61 and the nut 63 through hollow eccentric adjusting screw 6, adopt above-mentioned regulative mode, can make toolframe 2 that whole moving taken place:
When 1, through adjusting hollow eccentric adjusting screw 6 guide pillar 3 being fixed on " 0mm " scale together with hollow eccentric adjusting screw 6, this skin graft machine of cutting can cut the uniform thickness skin graft, and skin graft thickness is the distance of blade and arc surface 11;
2, through regulating hollow eccentric adjusting screw 6 guide pillar 3 is fixed on (≠ 0) when departing from " 0mm " scale position together with hollow eccentric adjusting screw 6, can cut by thick to thin perhaps by being thinned to thick skin graft;
In addition, orbit hole 13 both sides indicate scale, and to 8mm, " 0mm " scale is on the center of circle of circular arc drum face 1, so operator can accurately control guide pillar 3 and depart from " 0mm " graduated degree together with hollow eccentric adjusting screw 6 from-8mm for scope.
Toolframe handle 4 is housed on the toolframe bogie side frame 22, spurs toolframe about being used for, thereby make blade horizontal movement on the skin that circular arc drum face 1 has glued, cut skin graft more easily.Toolframe bogie side frame 22 two ends all are provided with the screw of mounting cutter frame handle 4, therefore, get used to using left hand and get used to making right-handed operator to cut machine for this skin graft of handled easily.
On the arc surface 11 uniform fine line is arranged on the circular arc drum face 1, arc surface 11 is sticked on the skin with glue or double faced adhesive tape more easily.
Compare with existing equipment, the present invention has following advantage:
1, this skin graft machine of cutting can cut from thin and be smoothly transitted into thick gradually or be smoothly transitted into thin skin graft gradually from thick;
2, this skin graft machine of cutting can cut from thin and be smoothly transitted into thick gradually or be smoothly transitted into thin dermal tissue sheet gradually from thick;
3, this skin graft machine of cutting can cut skin graft or the dermal tissue sheet that is smoothly transitted into thin uniform thickness then (thickness is with thin consistent) gradually from thick;
4, this skin graft machine of cutting can cut from uniform thickness and be smoothly transitted into thin skin graft or dermal tissue sheet then gradually;
5, the thickness of the not uniform thickness skin graft that cuts of this skin graft machine of cutting or dermal tissue sheet is adjustable;
This utility model can be widely used in the bark fetching operation before the skin grafting, and the preceding sampling operation of bioassay (live body).Can cut the uniform thickness skin graft; More be applicable in skin grafting, cut from thin be smoothly transitted into gradually thick, from thick thin skin graft or the dermal tissue sheet of being smoothly transitted into gradually; And, make from shallow and be smoothly transitted into dark skin excision wound model in order to study skin trauma regeneration and scar healing.Through cutting experiment measuring, the skin graft that cuts is respectively uniform thickness (its scope is 0-12mm), is smoothly transitted into thick gradually and is smoothly transitted into thin skin graft gradually from thick from thin, has reached Expected Results.
