Technical field
The utility model relates to the field of medical instrument technology, more particularly to one kind is easy to operate, wound face is small, is easy to heal
And cut the high skin biopsy knife of precision.
Background technique
Up to the present skin disease has more than 2,000 kinds, many diseases are with the naked eye different in terms of diagnosis surely distinguishes accurate,
Syringocystadenoma, trichoepithelioma, verruca plana of such as common generation in face, but this kind of disease is in a pathology on piece then mesh
So.There are similar pathological manifestations generally in terms for the treatment of, it can take identical therapeutic scheme.So the country carries forward vigorously
Skin biopsy is one and significantly works.Skin biopsy and skin biopsy histopathological examination, in examining for dermatology
Very important status is occupied in controlling, it for dermopathic diagnosis, treatment, judging prognosis, understand that the generation of disease all plays
Leading role is that dermatology is most practical, the most inspection of diagnostic value.Since the country carries out dermal pathology inspection lag, suffer from
Person sees a doctor the also not no habit of biopsy, is the inspection for having wound there are also biopsy, domestic skin biopsy specific purpose tool not yet,
So this most necessary inspection of biopsy does not apply to clinic but well.
Currently, there are mainly three types of the acquisition methods of skin histopathology's sample: operation and cuts method at harvesting, trepan method.
Wherein, operation harvesting and to cut method be directly to be cut down the skin of morbidity to obtain sample with scalpel, because being not easy
Operation, stability is poor, low efficiency, and wound face is big, cutting precision is not high and bleeding is more and is restricted in clinical application.
Trepan method is generallyd use in various big hospital at present, cuts difficult person, skin after materials especially suitable for smaller early stage skin lesion or operation
Skin defect is circle, is not easy to close linear slit, and easily form scar sample appearance after suturing.Therefore above method in clinical use all
It has some disadvantages.
Utility model content
The purpose of the utility model is to provide a kind of skin biopsy knife, makes it easy to operate and keep, realize fast accurate
Cutting；Meanwhile so that taking the wound face of skin small, notch is easy to heal, and is less prone to scar, to improve the safety of skin biopsy
Property.
For this purpose, the utility model provides a kind of skin biopsy knife, it to be used for skin biopsy and skin biopsy histopathology
It checks, the skin biopsy knife includes the blade and elastic mounts of integral structure, and the blade includes the cutting edge being oppositely arranged
