Abstract
The utility model relates to the field of medical equipment, concretely relates to department of general surgery is with skin tissue perforator, including handle of a knife and drill bit, its characterized in that: the circular cutter sword of drill bit for having two sawtooth, two sawtooth become symmetric design, the length of side of every sawtooth equals with the radius of circular cutter sword, and the design of the no matter blade of tip edge. The utility model discloses the beneficial effect who has is: pressure is mastered easily during the operation, and is sharper because of the edge of a knife becomes the cockscomb structure, and the rotation just can get into sample non -deformable, it can complete keeping in the perforator to operate when correct the sample, avoids using pincers and tissue to cut, and operating is simplified also can avoid the structural style of the whole pathological change of pincers destruction, the surface of a wound is little, may not sew up in case of necessity, and it is drawn materials and more accords with pathologic sampling's requirement, more has the clinical practice and is worth.
Description
Technical field
This utility model is related to a kind of medical apparatus and instruments and in particular to a kind of department of general surgery skin histology borer.
Background technology
Skin biopsy is a kind of pathologic finding means that department of dermatologry is commonly used, and refers to the skin at excision or a certain position of trepan
Skin or mucous membrane tissue, by tissue staining, with the clear and definite or a certain diagnosis of prompting.For diagnosing cutaneous tumor, viral skin
Disease, bulla class dermatosiss, psoriasises, lichen planuss and the dermatosiss leprosy of pathogen, deep mycosiies etc. can be found.Skin is lived
Inspection art plays conclusive effect for the diagnosis of disease.But biopsy is a kind of damaging operation, clinicist must take into
To the property of infringement, the accuracy rate of diagnosis of biopsy, if the position of impact beauty treatment and biopsy.Skin biopsy includes：Cut work
Inspection art, boring biopsy, Biopsy art, wedge excision biopsy.
Boring biopsy due to its simple and quick it is easy to grasp, specimen rule, complete, cosmetic result are good, clinical
Doctor widely uses.Apparatus used in boring biopsy is sawtooth cutaneous punch, is the circular pocket knife of diameter 3-6mm, is suitable for
In microlesion, or pathological changes are limited only to epidermis or corium, or the inconvenient case of surgical excision.According to different diseased regions
Choose suitable trepan device, left hand fixes skin of drawing materials, right hand-held drilling pierces skin and reaches necessarily perpendicular to surface, rotation
Depth, exits borer, carefully extracts tissue with toothed forcepss, cuts off substrate with shears, and gel sponge oppresses wound, and wraps up.
The usual knife edge of existing sawtooth cutaneous punch is not sharp, often takes less than pathological tissues when the located subcutaneously tissue of pathological changes, and is carrying
Take and toothed forcepss during tissue, will be used, be easily destroyed the version of whole pathological changes.
Utility model content
According to above the deficiencies in the prior art, this utility model provides a kind of department of general surgery skin histology borer, passes through
Structure optimization is carried out to the cutting edge of borer drill bit so as to cut quick, specimen more specification, and in operation can
Avoid the use of toothed forcepss.
A kind of department of general surgery described in the utility model skin histology borer, including handle of a knife and drill bit it is characterised in that：
Described drill bit is the circular blade with two sawtooth, and two described sawtooth become symmetric design, the length of side of each sawtooth with
The radius of circular blade is equal, and tip edge also becomes Cutting Edge Design.
Wherein, preferred version is as follows：
Described handle of a knife includes handling section and changeover portion, and described handling section is cylindrical structural, and surface is through annular knurl
Process, to increase coefficient of friction, be easy to hand-held；Described changeover portion is circular platform type structure, and the minor face position of circular platform type
Place is connected with drill bit.
It is to be flexibly connected between described changeover portion and drill bit, can adopt threaded, it would however also be possible to employ magnetic connects.
Therefore the drill bit of the different model specification that can change the outfit on same handle of a knife as needed, so that skin histology borer is operated more convenient.
Also include protective cap, described protective cap and changeover portion phase clamping.When not in use, protective cap can play right
The protective effect of drill bit, it is to avoid the interference of dust antibacterial.
This utility model is in operation：Before boring excision or biopsy, diameter is selected according to the size of skin lesion, property and position
Appropriate drill bit.Operation consent is more to be accurately positioned, and with methylene blue, operative site is marked.It should just determine after operation starts
Normal skin texture, launches skin with thumb and forefinger along skin texture vertical direction, postoperative unclamp skin, otch should be in ellipse
Shape, is so conducive to suturing in line of cut and no Canis familiaris L. ear is formed.Rotate clockwise along axle center, enter the rotation of respective depth rear-inclined
Circle, using the root of saw cut sample, what sample can be complete is saved in drill bit.With hook pin, tissue is taken after extracting
Go out.
This utility model is had an advantageous effect in that：(1) when operating, pressure is easily mastered, because the edge of a knife becomes zigzag, more
Plus sharp, rotation can enter, and specimen is unlikely to deform；(2) what when operation is correct, specimen can be complete is retained in borer, it is to avoid
Using toothed forcepss and tissue shear, simplify operation it is also possible to avoid toothed forcepss to destroy the version of whole pathological changes；(3) wound surface
Little it may be necessary to need not suture, it is drawn materials and more meets the requirement of pathologic sampling, with more clinical value；(4) handle of a knife and
Can be for being flexibly connected between drill bit, the drill bit of the different model specification that can change the outfit on same handle of a knife as needed, make skin group
Knit borer operation more convenient；(5) also there is protection cap, when not in use, protective cap can play the guarantor to drill bit
Shield acts on, it is to avoid the interference of dust antibacterial.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the side view of Fig. 1；
In figure：1st, handling section 2, changeover portion 3, drill bit 4, sawtooth 5, protective cap.
Specific embodiment
With accompanying drawing, this utility model is described further with reference to embodiments.
Embodiment 1：
A kind of department of general surgery skin histology borer, including handle of a knife and drill bit 3, described drill bit 3 is with two sawtooth 4
Circular blade, described 4 one-tenth symmetric designs of two sawtooth, the length of side of each sawtooth 4 is equal with the radius of circular blade, and tooth
Edge also becomes Cutting Edge Design.
Described handle of a knife includes handling section 1 and changeover portion 2, and described handling section 1 is cylindrical structural, and surface is through rolling
Flower is processed, and to increase coefficient of friction, is easy to hand-held；Described changeover portion 2 is circular platform type structure, and the minor face position of circular platform type
Put place to be connected with drill bit 3.
