Description
Technical field
The utility model is related to a kind of medical instruments, and in particular to a kind of department of general surgery's cutaneous punch.
Background technology
Skin biopsy is a kind of common pathologic finding means of dept. of dermatology, passes through excision or the skin at a certain position of trepan
Skin or mucous membrane tissue come clearly or prompt a certain diagnosis.For diagnose skin neoplasin, virus dermatopathy, bleb class skin disease,
Psoriasis, lichen planus and the skin disease leprosy of pathogen, deep mycosis etc. can be found.Biopsy drill due to its operation letter
It is single quick, it is easy to grasp, sample rule, complete, cosmetic result is good, is widely used by clinician.
Existing cutaneous punch pierces skin in rotation and exits after drill up to certain depth, it is necessary to using tooth tweezer, carefully
Tissue is extracted, substrate is cut with scissors.Operating procedure is complicated, fragile entire pathological tissues structure.
Utility model content
The purpose of this utility model is to provide a kind of extraction tissue simplicity, the complete department of general surgery's skin of sample cut bores
Hole device.
The utility model is realized using following technical solution：
Department of general surgery's cutaneous punch, including sleeve, cutter head, swing arm, guide rod, connecting rod, the sleeve bottom end is hinged with cutter head,
Described connecting rod one end is fixedly connected with cutter head inner wall, and the other end is hinged with guide rod bottom, and the guide rod top, which is fixedly connected, blocks, institute
The setting of swing arm bottom and matched inner fovea part of blocking are stated, described to block in inner fovea part, the sleeve passes through screw thread with swing arm
Flexible connection, swing arm can be moved back along sleeve precession with rotation.
Described, cutter head is cambered surface triangle shape；
Described, cutter head bottom is to face the rectangle edge of a knife directly；
Described, there are the cutter heads that at least two are uniformly distributed in sleeve bottom end；
Described, connecting rod quantity matches with cutter head quantity.
The beneficial effects of the utility model are：
(1) department of general surgery's cutaneous punch described in the utility model, is provided with and blocks, precession or rotation the derotation bar when, can protect
It is radially motionless to hold guide rod, moves up and down vertically；
(2) department of general surgery's cutaneous punch described in the utility model, is provided with connecting rod, controllable by moving up and down for guide rod
The opening and closure of cutter head processed；
(3) department of general surgery's cutaneous punch described in the utility model by the cooperation of all parts, can directly take out skin
Tissue, extraction is easy, and tissue is complete.
Description of the drawings
Fig. 1 is department of general surgery's cutaneous punch structure diagram；
In figure：1st, sleeve；2nd, cutter head；3rd, swing arm；4th, guide rod；5th, connecting rod；6th, block.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, department of general surgery's cutaneous punch described in the utility model, including sleeve 1, cutter head 2, swing arm 3, guide rod
4th, connecting rod 5,1 bottom of sleeve is hinged with cutter head 2, and described 5 one end of connecting rod is fixedly connected with 2 inner wall of cutter head, the other end and guide rod 4
Bottom is hinged, and 4 top of guide rod, which is fixedly connected, blocks 6,3 bottom of swing arm set with 6 matched inner fovea parts of blocking, it is described
6 are blocked in inner fovea part, the sleeve 1 is flexibly connected with swing arm 3 by screw thread, and swing arm 3 can be moved back along 1 precession of sleeve with rotation；
The cutter head 2 is cambered surface triangle shape；2 bottom of cutter head is to face the rectangle edge of a knife directly；There are four to be uniformly distributed in 1 bottom of sleeve
Cutter head 2；5 quantity of connecting rod matches with 2 quantity of cutter head.
When precession or rotation derotation bar 3, blocking 6 can keep guide rod 4 radially motionless, move up and down vertically, 5 one end of connecting rod
2 inner wall of cutter head is fixedly connected with, the other end is hinged with 4 bottom of guide rod, passes through the opening for moving up and down controllable cutter head 2 of guide rod 4
With closure, the extraction that skin histology is not completed by other instruments is realized.
The use process of the utility model is as described below：By precession or rotation derotation bar, adjust cutter head make cutter head parallel to
Sleeve is axial, and left hand fixes materials skin, and right hand-held drilling pierces skin up to a depthkeeping perpendicular to surface, rotation swing arm
Degree keeps drill rotation derotation bar, collapses cutter head, skin histology is isolated in by cutter head in cutter head, completes carrying for skin histology
It takes.
Certainly, the above is only the preferred embodiment of the utility model, it is impossible to is construed as limiting new to this practicality
The scope of embodiments of type.The utility model is also not limited to the example above, and those skilled in the art are in this reality
With all the changes and improvements made in new essential scope etc., the patent covering scope of the utility model should all be belonged to
It is interior.
