Dissect frame
Technical field
The present invention relates to dissection frame, be specifically related to a kind of dissection frame tied up pig, kill pig, dissect one.
Background technology
Dissection is a medical science, biology term, refers to special cutter, cuts a human body or animal and plant body is cut open.Anatomy (Human Anatomy) is the science of researching human body normal morphology structure.Belonging to the morphology category of bioscience, is an important core curriculum in medical science.
Dissecting frame is experimental facilities the most frequently used in laboratory, operating room or Medical Devices, no matter be human dissection, or zootomy generally all completes on dissection frame.Traditional dissection frame generally comprises the bed board supported by footpost, and structure is very simple.Carrying out when dissected, the remains of people or spoil are being placed on bed board, then carrying out dissecting, cutting remains for people or corpse provides carrier, bringing conveniently.There is a kind of senior dissection frame with flushing system in the market, can rinse at any time in anatomic course, brought conveniently for dissecting and observing.At present, no matter which kind of dissects frame, is all generally that remains or the spoil of dissection people uses, therefore to dissecting the too not high requirement of frame.For for the laboratory anatomy experiment pursuing real time data and True Data position target, necropsy can not obtain the most real institutional framework state, therefore under lab generally all selects vivisection to operate.But vivisection is also only limitted to animal, for human body vivisection not only to be legally binding, also unrealistic, therefore generally select the family pig similar with human tissue structure as vivisection object.Because family's pig build is comparatively large, wild nature remains, counteragent is very big, carry out vivisection and very easily come to harm, and adult family pig weight is generally at 400-500 jin, at least need 4 adults' ability lifts to move or control, therefore generally select family's pig cub or postanesthetic adult family pig to carry out vivisection.But so there is drawback, that is: the institutional framework of cub is not grown perfect yet, and postanesthetic body function is not normal condition, the experiment made on the living meaning of adult family pig therefore can not be replaced.Because experiment purpose is different, required experimental subjects is not identical yet.As in order to need selection average adult man pig when researching human body is organized, need research sex to need to select sow and boar, in order to the family pig then needing selection one to have to this disease during logist's pig disease with when growing.Therefore in order to best experimental subjects (family pig) can be obtained, pig farm must be arrived and select all satisfactory pigs such as age, build, health.
The normal way adopted is at present, a pig is chosen by researcher, then many people are employed to be pressed down by force by family pig, then the forehoof of family's pig body bilateral both sides and rear hoof iron wire are fixed, such family pig just can not be run, then its lift to move to be dissected on frame to tradition and is started bloodletting by many people, dissects after bloodletting from family's pig belly.Owing to there is no special to tie up pig, kill pig, dissecting integrated device, in whole process, particularly tie up pig and belly when dissected must by many people by force by household pig, otherwise the resistance of family pig can cause blood to flash, and therefore operates to bother very much, require great effort very much.Also there is following drawback in aforesaid operations, and 1, when bloodletting, forehoof and the rear hoof of family pig bundle, and therefore can cause thrombosis, easily form extravasated blood, be unfavorable for observation and analysis in the institutional framework after dissection; 2, at when dissected, need support staff to hold four hoofs of household pig, so that fully expose abdominal cavity, open dissection visual area, so just can be convenient to observation, study, analyze.
