The pressing operation desk comprises an oblique rod, a placing rod, a pressing rod and an upright rod, the bottom of the upright rod is perpendicularly connected to the placing rod, the bottom of the oblique rod is connected with one end of the placing rod, the middle of the oblique rod is fixedly connected with the upper portion of the upright rod, and a connecting end of the pressing rod is connected with the top of the upright rod; the biopsy knife comprises a ring cutting knife, a knife holder and a connecting seat, the ring cutting knife is arranged in the knife holder, and the knife holder is connected with one end of the hilt by the connecting seat; and the other end of the hilt is fixedly connected to the top of the oblique rod. The skin biopsy sampler has the advantages that depths can be controlled when specimens are collected, so that the sampling success rate is greatly increased, and collected samples are uniform and neat.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of skin biopsy sampler.
Background technology
There is important value in skin histopathology to dermopathic diagnosis, or even the goldstandard of some dermatosiss diagnosis, to the generation of understanding disease, develop, lapse to, body general body state and the selection of Therapeutic Method all had most important theories meaning and more practical value.Want to obtain desirable pathology picture, regular specimen must be arranged.
At present, the method for dermatological specimens collection has three kinds: operation cuts method, trepan method and cuts method.Wherein, operation cuts method and the method that cuts is directly the skin of morbidity to be cut down and directly obtains sample with scalpel, because of wound big, hemorrhage many, operative scar is bigger, in clinical practice, be restricted.The trepan method generally adopts at various big hospital at present, is specially adapted to less early stage skin lesion or is confined to show shallow place or operation cuts difficult person.Corneal trephine is that department of dermatologry is got one of the most frequently used instrument of pathology sample, and this trepan front end has circular cutter, after trepan is got into patient's subcutaneous tissue, takes off trepan, clamps sample with tweezers, cuts sample with knife or shears at fat deposit.The weak point of this trepan is: do not have scale on the Ring-shape cutter, makes the degree of depth of drawing materials wayward, and not enough as the degree of depth, can cause the failure of drawing materials; The manual spiral mode that enters skin is taked in drilling through of operation trepan, and greatly random, accuracy is not enough.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of simple in structure, easy to operate, the skin biopsy sampler that can precisely control the degree of depth of drawing materials is provided.
For achieving the above object, this utility model is taked following technical scheme.
A kind of skin biopsy sampler, comprise handle of a knife, biopsy cutter and pressing operation platform, wherein, described pressing operation platform comprises brace, places bar, depression bar and vertical rod, the bottom of described vertical rod is vertically connected at described placement bar, the bottom of described brace is connected with an end of described placement bar, fixedlys connected with the top of described vertical rod in the middle part of described brace, and the link of described depression bar is connected with the top of described vertical rod; Described biopsy cutter comprises Ring-shape cutter, tool rest and Connection Block, and described Ring-shape cutter is arranged in the tool rest, and described tool rest is connected with an end of described handle of a knife by Connection Block; The other end of described handle of a knife is fixed in the top of described brace.
Further, described vertical rod is provided with cylindrical spring.
Further, described Connection Block is connected by screw buckle with described handle of a knife.
The beneficial effects of the utility model are: skin biopsy sampler of the present utility model adopts Ring-shape cutter detachable, polytypic, can select the Ring-shape cutter of different model according to the sampling needs, and depth controlled, has improved the sampling success rate greatly.The pressing operation platform utilizes lever and cuts the principle that refers to cutter, and the pressing type operation Ring-shape cutter enters skin histology, reduces randomness, has improved accuracy.
Description of drawings
Fig. 1 is the structural representation of this utility model skin biopsy sampler.
Among the figure, the 1-brace, the 2-depression bar, 3-places bar, 4-vertical rod, 5-handle of a knife, 6-Connection Block, 7-tool rest, 8-Ring-shape cutter, 9-cylindrical spring.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
Skin biopsy sampler of the present utility model as shown in Figure 1, comprise handle of a knife 5, biopsy cutter and pressing operation platform, wherein, the pressing operation platform comprises brace 1, places bar 3, depression bar 2 and vertical rod 4, the bottom of vertical rod 4 is vertically connected at places bar 3, the bottom of brace 1 is connected with an end of placing bar 3, fixedlys connected with the top of vertical rod 4 in the middle part of brace 1, and the link of depression bar 2 is connected with the top of vertical rod 4; The biopsy cutter comprises Ring-shape cutter 8, tool rest 7 and Connection Block 6, and Ring-shape cutter 8 is arranged in the tool rest 7, and tool rest 7 is connected with an end of handle of a knife 5 by Connection Block 6; The other end of handle of a knife 5 is fixed in the top of brace 1.
As preferably, vertical rod 4 is provided with cylindrical spring 9.By cylindrical spring is set, can control the dynamics of pressing, make sampling more even, regular.
As further preferred, Connection Block 6 and handle of a knife 5 are connected by screw buckle.
When using skin biopsy sampler of the present utility model to take a sample, can be according to the skin biopsy needs of taking a sample, in tool rest, install be suitable for model make the Ring-shape cutter of disinfecting, free end by the manual pressing operation platform of doctor depression bar, allow Ring-shape cutter vertically enter skin histology, consider as required to enter the degree of depth, cut sample by shears again, finish the biopsy sampling operation.
Use skin biopsy sampler of the present utility model, the controlled degree of depth and the dynamics of producing sample improved the regularity of sampling success rate and sample greatly.This utility model is simple in structure, and convenience simple to operation is suitable for clinical application.
The above is preferred embodiment of the present invention only, is not to limit practical range of the present invention; If do not break away from the spirit and scope of the present invention, the present invention is made amendment or is equal to replacement, all should be encompassed in the middle of the protection domain of claim of the present invention.
