Description
Technical field
This utility model relates to the medical device technical field, and particularly skin biopsy borer technical field specifically is meant a kind of single-use skin biopsy borer.
Background technology
Diagnosis is extremely important to the control of disease, and correct diagnosis has been arranged, and just can carry out effectively preventing.The diagnosis of department of dermatologry must be carried out analysis-by-synthesis according to medical history, physical examination and lab testing.The dermatologist usually diagnoses according to skin colour change, erythra form with the personal experience, takes skin histopathology to check for difficult dermatosis.At present, the indication at department of dermatologry execution skin biopsy has: 1, cutaneous tumor and precancerosis; 2, leprosy and tuberculosis of skin; 3, bullous dermatosis and allergic vasculitis; 4, the dermatosis that has pathogen; 5, the dermatosis that has relative specificity change in organization; 6, some the inflammatory skin disease that has certain specific lesions.
The dermal pathology inspection is that live body is gathered skin and made 3mm～5mm slab and be placed on the microscopically observation of cell and learn and change.At present Skin biopsy gets that apparatus must be sharp keen when adopting, and avoids damaged tissue as far as possible, in time puts into fixative.Method can be divided into two kinds of surgical method and boring methods.
Boring method is simple and easy to do, is applicable to that disease decreases little or the surgical method inconvenient case of drawing materials.Method is as follows: 1, routine disinfection skin, drew materials in several minutes after the local anaesthesia; 2, select the borer in suitable aperture according to the skin lesion size, left hand is skin fixedly, the right hand simultaneously rotates at the position of drawing materials with borer, one faces down firmly, (general requirement reaches subcutaneous tissue) takes out borer when getting into appropriate depth, picks up the specimen edge gently with tweezers, specimen is mentioned, specimen is cut off from the bottom with little shears; 3, specimen is put into formalin fixed liquid bottle immediately; 4, wound hemostasis by compression, pressure dressing.
Skin biopsy is to many dermopathic diagnosis, and classification is treated and judging prognosis has very significant values.But skin biopsy is drawn materials greatly now, stay cicatrix easily, owing to stay tangible operative scar behind the skin biopsy, patient's skin biopsy of usually being unwilling to accept, so just make skin biopsy can only be used for the diagnostic techniques of difficult disease, and can not become the diagnosis and treatment technology of dermatosis common disease; And existing do not have scale with borer, and operator is not easy to grasp the thickness of drawing materials; Be metal material now, use repeatedly, pollute easily with later sterile-processed with borer.
Therefore, need provide a kind of new skin biopsy borer, it is difficult for staying cicatrix, and is simple to operate, can not pollute.
The utility model content
The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, and a kind of single-use skin biopsy borer is provided, and this single-use skin biopsy borer design is ingenious, it is difficult for staying cicatrix, can be used for the skin routine examination, simple to operate, can not pollute.
To achieve these goals, single-use skin biopsy drilling tool of the present utility model has following formation:
This single-use skin biopsy borer comprises handle and the sampling head that is connected with described handle, is characterized in that the free-ended bore of described sampling head is 0.3mm～0.5mm.
Preferably, the free end of described sampling head is provided with the length graduation mark along its length.
Preferably, the free end of described sampling head is cylindrical.
Preferably, the described sampling head described handle that removably connects.
More preferably, described sampling head is connected with described handle by helicitic texture.
More preferably, described sampling head is the rustless steel sampling head.
Preferably, described single-use skin biopsy borer also comprises headgear, and described headgear has container cavity, and described headgear is socketed on the described handle, and described sampling head is positioned at described container cavity.
The beneficial effects of the utility model are:
1, the sampling head bore of single-use skin biopsy borer employing of the present utility model is little, design ingeniously, postoperative patient is difficult for staying the operation vestige, and skin biopsy can become department of dermatologry diagnostic method commonly used like this, no longer be that difficult patient uses, can be used as routine examination;
2, the free end of the sampling head of single-use skin biopsy borer of the present utility model has the length scale, is convenient to operator and grasps the thickness of drawing materials easily, and is easy to operate simple;
3, single-use skin biopsy borer of the present utility model is disposable, can not pollute, even can sampling head be disposable, so that when assurance can not pollute, saves material.

The specific embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.
See also shown in Fig. 1-2, what Fig. 1-2 showed is a specific embodiment of single-use skin biopsy borer of the present utility model, and it comprises handle 1 and the sampling head 2 that is connected with described handle 1, and the bore of the free end 3 of described sampling head 2 is 0.3mm～0.5mm.
Preferably, the free end 3 of described sampling head 2 is provided with the length graduation mark along its length.In this specific embodiment, the length graduation mark begins to be followed successively by 0.5cm, 1cm, 1.5cm and 2cm graduation mark to handle 1 direction from free end 3 ends, thereby makes operator grasp the thickness of drawing materials easily.Certainly, the free end 3 of sampling head 2 also can not be provided with the length graduation mark, at this moment needs sampling person to judge by rule of thumb, and the thickness of drawing materials is difficult for grasping.
In this specific embodiment, the free end 3 of described sampling head 2 is cylindrical.Certainly the free end 3 of sampling head 2 also can be other suitable shape, can be cylindricality, and its cross section can be a triangle, tetragon or other polygon; It also can be non-cylindrical shape.
