Description
Technical field
The invention belongs to medical bio engineered tissue measured film thickness equipment technical field, relate in particular to a kind of medical film thickness measurement device.
?
Background technology
All kinds of cardiovascular and cerebrovascular diseases have become human common disease, medically use more and more widely at the insertion type operation of such disease, to the also increase year by year of demand of insertion type apparatus.A kind of as in the insertion type apparatus of medical support shown the curative effect with good restraining cardiovascular and cerebrovascular disease in clinical testing, be widely used in removing such sufferer.Medical support develops into today, and the material that is applied in the medical support has nonmetallic materials such as metals such as 316L, tweezer titanium alloy, cobalt-base alloys, pure iron, magnesium alloy and macromolecule.Studies show that according to up-to-date insertion type medical skill, insertion type operation success or not and insertion type product self and biological tissue of human body compatibility are closely related, the compatible time is faster, compatibility is better, and this depends on insertion type apparatus and biological tissue of human body compatibility, the success or failure of final decision insertion type operation.Just because of this, medical stent and biological tissue of human body consistency problem become the research focus.The conventional metals support generally all is to carry out surface treatment and be assembled into medical mounting system by Laser Processing and relevant postprocessing working procedures, thereby directly perform the operation from artery implant into body angiosis affected part by insertion type, and directly contact with the human vas wall at the sufferer place, after operation, observe this medical support in 3 ~ 6 months whether finally and the human vas tissue compatible, mutual exclusive problem can not take place and cause operative failure, experimental results show that this insertion type success rate of operation that directly medical metal stand is contacted with human body is not high.
In order further to improve the insertion type success rate of operation, a kind of braided support at metal support outside surface applying one deck bioengineered tissue film progressively is applied, this support is by being fitted in medical metal stand outside surface by the pressing technology with the bioengineered tissue of one deck similar heart film at the medical metal stand outside surface, make behind the implanted human body of this support, directly be to contact with the human vas wall by this bioengineered tissue, both can be directly compatible, can not produce the extra repulsive effect, greatly improve the insertion type success rate of operation.But in this braided support process, bioengineered tissue thickness evenness to the similar heart film that is fitted in the medical metal stand outside surface proposes high requirement, in case this skin depth homogeneity is bad, will cause the outer tension force unevenness of whole braided support, thereby make that this rack outer surface and vascular wall applying effect are inconsistent, and influence both compatibility, and finally cause the insertion type success rate of operation not have internal to improve.
At present, the unprofessional relevant device that is used for precision measurement medical bio engineered tissue film on the market, therefore, industry is badly in need of exploring a kind of scheme, is used for the measuring equipment of medical bio engineered tissue measured film thickness so that a kind of specialty to be provided.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of medical film thickness measurement device, to solve in the market the problem of the equipment that specialty not measures automatically at medical bio engineered tissue film thickness, and braided support that meet insertion type requirements of operation qualified for the quality of production provides hardware guarantee.
For achieving the above object, technical scheme of the present invention is:
A kind of medical film thickness measurement device includes base, is arranged at work stage on the base, is arranged at a closed-in construction on the work stage, is arranged at the double vertical gauge head on the upper and lower crossbeam of closed-in construction; Described double vertical gauge head includes gauge head and following gauge head, wherein go up gauge head and can adjust relative height automatically according to medical bio engineered tissue change in film thickness, and gauge head has adjustment and last gauge head light beam coaxiality function down; In the measuring process, the synchronous side-to-side movement of upper and lower gauge head, and tested medical bio engineered tissue film is fixed on the work stage in the middle of two gauge heads, and do with work stage and to seesaw.
Further, during measurement, adopt noncontact scanning survey mode, upper and lower gauge head does not contact with medical bio engineered tissue film in the measuring process.
Further, be fixed with the linear axis Y-axis on the described grouan platform, and be positioned at fixedly on gantry with the orthogonal linear axis X-axis of Y-axis.
Further, be fixed with the Z axle on the entablature of described closed-in construction.
Further, the described gauge head of going up is fixed on the Z axle that moves up and down, and gauge head is fixed on the precise 2-D angular setting platform on the sill of closed-in construction down; Adjust the measuring beam alignment that gauge head under platform adjustment is gone up gauge head relatively by this, guarantee to measure up and down gauge head in measuring process correlation on the same point of medical bio engineered tissue film.
Further, can descend gauge head to carry out Z axle relative height relatively on the described upward gauge head adjusts automatically.
Medical film thickness measurement device of the present invention adopts non-contact measurement mode, double vertical gauge head layout, automatically the medical bio engineered tissue film to whole breadth carries out the scan-type measurement, measuring process does not have any damage to medical bio engineered tissue film, measuring accuracy height, stable performance.
