Description
Technical Field
The invention belongs to the field of animal experiment instruments, and particularly relates to a circular skin taking area outer contour cutting device.
Background
In experimental studies of skin defects in animals, it is often necessary to involve cutting the entire or upper skin of the appropriate area to form a model of the skin defect. In the process, the skin defect with the outline (such as circular shape and oval shape) of the smooth curve is a common skin-taking shape, so that the periphery of the skin defect area can be ensured to have a relatively consistent shape, the growth trend of each boundary skin can be conveniently and intuitively judged, and the healing condition can be evaluated.
In the repair of skin defects, it is also often necessary to remove the skin from a healthy skin area and to graft the skin sheet to the skin defect area. However, the repair of the skin defect area is focused on in the operation, and the degree of focus is insufficient after the healing of the skin removing area, which is obvious from the related skin removing procedure. The skin removing devices currently used in skin removing operations can be generally divided into two categories: (1) The traditional roller dermatome is characterized in that the dermatome is very large in the cut dermatome, the edges of the dermatome are quite irregular, the thickness of the cut dermatome is also uneven, and the influence of the pressure applied by the hand of a cutter holder is great; (2) The skin removing device is used for cutting the skin with the diameter of 0.5-5 mm, and the device usually needs to use a skin test needle to bulge a certain part of the body and then use a skin removing knife of the skin removing device to remove the skin. Although the device can cut the skin sheet with the outline of the smooth curve, for the microparticle skin with small diameter, the effect of slight difference of thickness on transplantation is small, and once the device is used for forming the skin defect wound surface for animal experiments, the difference of thickness can be amplified, so that the experiments are error.
Therefore, the existing skin removing equipment for removing skin to carry out transplanting repair cannot be used in experimental researches on skin defect animals, and the prior art is lack of equipment capable of simultaneously marking and positioning the outer contour of a skin removing area and then cutting the outer contour.
In the experimental research process of skin defect animals, most of the animal skin is manually drawn on the body part of the experimental animal in advance, and then the skin is cut by a skin cutter according to the drawn circular mark; or adopting a round article (such as a coin) as a medium, pressing the round medium on the peeling area, and then directly cutting the round medium by a blade around the periphery of the round medium to form the peeling boundary. These operations have the disadvantage that: (1) Because the skin taking range is smaller, the blade is improperly operated, and various problems such as the change of the size of an actual cutting area, uneven saw-tooth-shaped cutting surface edge, the cutting of the skin taking area by the blade and the like are easily caused by skin wrinkles; (2) Different experiments have different requirements on the skin taking depth of the skin taking area, no auxiliary positioning equipment is provided, and operators are easy to occur the condition of uneven skin thickness only by experience operation, so that experimental errors are increased.
Based on the above problems, it is necessary to develop a skin taking region outline cutting device specially used for experimental study of skin defect animals.
