Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of dress that aspiration biopsy is carried out by laser aiming
It sets.
Background technique
Referred to as " biopsy ", also known as surgical pathology inspection referred to as " is examined " outside for biopsy (biopsy)；Refer to and sees patients
Disconnected, treatment needs cut from patient's body, clamp to take or puncture etc. and take out pathological tissues, carry out the technology of pathological examination.It
It is most important part in Diagnosis pathology, specific histopathological diagnosis, quilt can be made to most inspection cases
As clinical final diagnosis.
Making a definite diagnosis for many diseases needs to make check pathological section, to obtain pathological tissue, is especially hidden in body interior
Pathological tissue, need to carry out puncture sampling, existing Aspiration method, is after puncture needle is punctured into mass, to utilize note at present
The principle of emitter negative pressure absorbing makes every effort to obtain a little pathological tissue or interstitial fluid body is diagnosed, but due to pathology living body group
It knits with tissue toughness, often because being difficult to be sucked out tissue, or the interstitial fluid body obtained not can be carried out pathological diagnosis, Er Qiexian
Some puncture process lack guidance, need medical worker by experience come localised puncture position, exist and puncture possibility devious
Property, and the depth punctured also can not accurately be held.For the beginner either insufficient medical worker of experience, using
It usually will appear the problem of puncturing deviation in journey, so that it is damaged to tissue, it is abnormally dangerous.
Summary of the invention
In order to solve the above problems existing in the present technology, it is carried out it is an object of that present invention to provide a kind of by laser aiming
The device of aspiration biopsy.
The technical scheme adopted by the invention is as follows: a kind of device carrying out aspiration biopsy by laser aiming, including promote
Device and aspiration biopsy device, the aspiration biopsy device are fixedly connected in propulsion device；
The propulsion device includes driving motor, drive rod and fixed plate, and the drive rod and driving motor are sequentially connected,
