Abstract
The utility model relates to a skin crusher for medical treatment, which can cut up skin. Before operation for transplantation microparticle skin treatment extensive burn, the utility model can cut skin into detritus which is smaller than 1*1 mm+[2], doesn't wreck skin organization, and the shearing efficiency ratio increases by 3-5 times than that of the manually operation by means of scissors. The utility model comprises a cartridges 1, a tube seat 2, a piston 4, a fixed blade 5, a cutting blade 6, etc., which has the advantages of simple structure, low cost and convenient operation.
Description
This utility model relates to the reciprocating chopping apparatus of a kind of cutter.
In plastic surgery operations medically, a kind of usefulness " transplant microgranule skin treating large-area burns " technology is arranged, this is that with patient one shreds into microgranule from body skin or allograft skin, is transplanted to then on the large-area burns position of 80-90%.If with shears with a 20 * 20cm
2Manual being cut into of skin less than 1 * 1mm
2Microgranule, took time 30～50 minutes, waste time and energy, efficient is low, and may influence operation and carry out smoothly.
The purpose of this utility model just provides a kind of efficient, easy chopping apparatus-medical onal machine, and it can shred into microgranule with skin at short notice, does not destroy skin histology.
Explain detailedly below in conjunction with accompanying drawing (1)-(6).This medical onal machine is made up of parts such as barrel 1, barrel seat 2, casing 3, piston 4, ledger-plate 5, cutting blade 6, connecting rod 7, crank 8, axle 9, bearing block 10, gear 11, gear 12, leading screw 13, support 14, guide post 15, trace 16, fork 17, pin 18, gear 19, handles (or slowspeed machine) 20.
Be positioned on two barrel seats 2 at casing 3 tops, all have about one to through hole, these two through holes are concentric.In two through holes, inject a barrel 1 respectively, left barrel 1 and left barrel seat 2 equal in length, another then is longer than barrel seat 2.In two barrels 1, a piston 4 is arranged respectively, its afterbody all is equipped with a pin 18.Ledger-plate 5 and is fixed on the left barrel seat 2 between two barrel seats 2, and 1 of right barrel props up ledger-plate 5 from the right side.Ledger-plate 5 and cutting blade 6 shape that all is rectangle, all there is a circle hole shape edge of a knife center, and edge of a knife diameter is less than barrel 1 diameter, and nose angle is 25 °～75 °.The edge of a knife of ledger-plate 5 is concentric with barrel 1, and respectively there is a guider screw edge of a knife both sides, and they lay respectively at accordingly, in two gathering sills of cutting blade 6 edge of a knife both sides, play the guiding role.Cutting blade 6 is driven by connecting rod 7 and crank 8, pumps.Crank 8 passes through a bearing block 10 and axle 9 driven rotary by gear 11.Gear 12 and gear 11 engagements, and drive leading screw 13 rotations.One screw hole is arranged at support 14 bottoms, is connected with leading screw 13, and there is a through hole at the middle part, be enclosed within 13 that parallel with leading screw, be fixed on the guide post 15 in the casing 3.Support 14 stretches out from the rectangle spacing hole at casing 3 tops, is connected with trace 16.At trace 16 two ends one fork 17 is arranged respectively, the pin 18 of piston 4 afterbodys inserts respectively in the fork 17.Therefore, the positive and negative rotation of leading screw 13 can make support 14 do the reciprocating motion of horizontal direction, moves simultaneously thereby drive two pistons 4 by fork 17 and pin 18.What be meshed with gear 12 is gear 19, and it is by handle (or slowspeed machine) 20 driven rotary.
The operating process of this apparatus is as follows: need put in the barrel 1 by skin chopped, load onto piston 4 from barrel 1 two ends again, pin 18 is inserted fork 17, shake handle 20 then, make piston 4 under the driving of support 14, the skin that promotes in the barrel 1 slowly passes through the edge of a knife.Meanwhile, the cutting blade 6 that is driven by connecting rod 7 will be through the skin chopping of the edge of a knife.When support 14 arrives at an end of spacing hole, handle 20 is rotated round about, this apparatus just repeats above work process.Like this repeatable operation can obtain the broken foam of skin of intact tissue.In addition, an available slowspeed machine and a Dian Ji Change replace handle 20 operations to switch.This apparatus improves 3-5 doubly than artificial with the shears operating efficiency, shreds a 20 * 20cm
2Skin, only need 5～10 minutes.
The advantage of the medical onal machine of this utility model is: the cutting efficiency height, do not destroy skin histology, and can reduce operator's labor intensity greatly.This apparatus structure is simple, cost is low, easy to use.
