The triangular-support-type skin slice cutter disclosed by the utility model can be used for cutting skin slices or derma tissue slices which are in gradually smooth transition from thinness to thickness, in gradual transition from thickness to thinness and are equal in thickness, thereby overcoming the defects that the traditional skin extractor can only cut large skin slices with equal thickness, is not capable of cutting the slices which is in gradually smooth transition from thinness to thickness and is also not capable of cutting derma tissue slices which are in gradually smooth transition from thinness to thickness.
Description
One, technical field
This utility model relates to the medical surgical operating theater instruments, is specifically related to a kind of triangle posture skin graft and cuts machine.
Two, background technology
In the skin graft operation process, need cut sometimes from thin thick skin graft or the dermal tissue sheet of being smoothly transitted into gradually; In addition, in order to study regeneration and scar healing behind the skin trauma, 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 " 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 " 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 drum dermatome just; Provide a kind of triangle posture skin graft to cut machine; This triangle posture 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; Thereby overcome the skin graft that existing dermatome can only cut large stretch of uniform thickness, can't cut from thin and be smoothly transitted into thick skin graft gradually, also can't cut from approaching problems such as being smoothly transitted into thick dermal tissue sheet gradually.
The present invention realizes through following technical scheme:
Like Fig. 1, shown in Figure 2, triangle posture skin graft cuts machine, comprising: drum body 1, guide pillar 2, toolframe 3, toolframe are regulated hold-down nut 4, toolframe handle 5, conduit 6 and are cut cleaner handgrip 7.
Toolframe 3 is made up of blade retainer 31 and toolframe bogie side frame 32.Conduit 6 run through bulging body 1 tripod summit, 11 both sides and with its welding, guide pillar 2 two ends are provided with external screw thread, guide pillar 2 passes the adjustment hole 33 on conduit 6 and the toolframe bogie side frame 32, toolframe is regulated hold-down nut 4 and is fastenedly connected at guide pillar 2 two ends.Blade is connected with toolframe 3 through blade retainer 31, cuts cleaner handgrip 7 and is fastenedly connected at conduit 6 middle parts.
Wherein, oval or rectangle adjustment hole 33 both sides on the toolframe bogie side frame 32 indicate scale, and scale range is 0mm-4mm, " 0mm " scale at adjustment hole 33 near blade retainer 31 1 sides.Toolframe is regulated hold-down nut 4 and can be slided along the adjustment hole on the toolframe bogie side frame 32 33, thereby changes the distance of cambered surface on blade and the circular arc drum face 12, reaches the purpose that cuts the different-thickness skin graft.Because toolframe bogie side frame 32 is marked with scale, so can accurately control the distance of cambered surface on blade and the circular arc drum face 12.
Wherein, Orbit hole 15 both sides of regulating on the stator 13 indicate scale; " 0mm " scale is at the end away from arc surface lower edge 16, and " 8mm " scale is 16 1 ends in the arc surface lower edge: when eccentric adjusting screw 14 was fixed " 0mm " scale, circular arc drum face 12 was 8mm with the spacing of tripod 11; When eccentric adjusting screw 14 was fixed on " 8mm " scale, circular arc drum face 12 was 0mm with the spacing of spider, and scale range is 0mm-8mm.So, scale directly shows the thickness that cuts skin graft: when circular arc drum face 12 when tripod 11 moves, the scale of regulating on the stator 13 becomes greatly gradually, arc surface and blade space become greatly simultaneously, cut the skin graft thickening.In view of the above, operator can accurately control the distance of tripod 11 and circular arc drum face 12.
As shown in Figures 2 and 3; Move up and down together with regulating stator 13 relative tripods 11 through promoting circular arc drum face 12; Be that eccentric adjusting screw 14 slides up and down in orbit hole 15; And through eccentric adjusting screw 14 circular arc drum face 12 and tripod 11 are fixed together, the height at circular arc drum face 12 two ends is changed:
1, regulating stator 13 high scales when identical when two ends eccentric adjusting screw 14, this skin graft machine of cutting can cut uniform thickness skin graft or dermal tissue sheet;
2, regulating stator 13 high scales at adjusting stator 13 high scales less than left side eccentric adjusting screw 14 when right side eccentric adjusting screw 14, when circular arc drum face 12 left sides begin to cut, can cut by thick to thin skin graft or dermal tissue sheet;
3, regulating stator 13 high scales at adjusting stator 13 high scales greater than left side eccentric adjusting screw 14 when right side eccentric adjusting screw 14, when circular arc drum face 12 left sides begin to cut, can cut by being thinned to thick skin graft or dermal tissue sheet.
Toolframe handle 5 is housed on the toolframe bogie side frame 32, is used to spur toolframe 3, thereby make blade horizontal movement on the skin that circular arc drum face 11 has glued, skin graft is cut more easily.Toolframe bogie side frame 32 two ends all are provided with the screw of mounting cutter frame handle 5, therefore, get used to using left hand and get used to making right-handed surgical staff to cut machine for this skin graft of handled easily.
On the cambered surface uniform fine line is arranged on the circular arc drum face 12, circular arc drum face 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 process before the skin grafting, and the preceding sampling process of bioassay (live body).Can cut the uniform thickness skin graft; More be applicable in skin graft transplant operation process, 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 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.
