Abstract
The invention provides a cutting device for a standard wound of fingertip skin of a primate. The cutting device for the standard wound of the fingertip skin of the primate aims at forming the cutting device on the basis of a primate animal bleeding time measuring model (wound cutting on fingertip skin), the cutting device can effectively, fixedly and accurately cut off the fingertip skin to form into a fingertip standard wound with relative fixed thickness, force and accuracy, accordingly accurate and effective testing data can be obtained and meanwhile an uncertain result and uncomfortable visual feelings caused by an unarmed operating behavior by directly cutting the fingertip through the surgical knife. According to the cutting device for the standard wound of the fingertip skin of the primate, a hollow pipe-shaped object with a suitable size is sleeved on a finger to fix the finger and flatly unfold the finger, a protruding position inside the pipe is used to fix a fingernail position (the front edge of a white line of the fingernail is served as the criterion for the length of the finger) of the finger, a cutter pressure device with a spring is arranged right above the protruding, the thickness of the exposed finger portion is relatively consistent when the finger is abutted,, then the upper cutter with the spring is pressed to cut off the fingertip skin, and the device is taken out conveniently, and the bleeding time is recorded.
Description
Technical field
The invention belongs to the biomedical devices field, be specifically related to a kind of primate finger tip skin standard wound and cut instrument.
Background technology
Bleeding time be clinically with zoopery in an index commonly used, for assessment of coagulation function, relevant disease and the anticoagulation of body and the effect of antithrombotic reagent etc.In primate (as people, monkey etc.) bleeding time is implemented, generally take at upper limb arm incision of skin standard otch, thereby measure the hemorrhage time to blood coagulation.Experiment showed, that utilizing finger tip end incision of skin is a simple and effective assay method, usually can, by operator with on the other hand the animal finger being fixed on cutting plate relatively, take scalpel to carry out otch with the another hands.The method that this hand operation forms otch has many shortcomings, for example: skin slides in the process of cutting, incision site is difficult for fixing and repetition, the size of the more difficult control of cutting dynamics, otch and thickness is wayward, the primate fingernail refers to that interventral distance is inconsistent, thereby causes the error of measurement result larger.Simultaneously, the risk that hand operation also exists operator to accidentally injure, visually easily cause sense of discomfort etc.The present invention staff has invented the device that a set of primates finger tip skin standard wound cuts, and can make up above deficiency.
Summary of the invention
The invention provides a kind of primates finger tip skin standard wound and cut device, this device can be more precisely, high duplication, fast and effeciently cut primates animal subject finger tip end skin, forms the standard wound, thereby the hemorrhage time to blood coagulation is measured.
The present invention is achieved by the following technical solutions.
A kind of finger tip skin standard wound cuts device, comprises finger sleeve 1, spring fitting device 2, thickness control device 3, blade pusher 4, spring 5, blade 6, described finger sleeve 1 is the hollow tube-shape thing, fluting 7 is arranged on the barrel position corresponding with blade 6, spring fitting device 2 is fixedly mounted on finger sleeve 1 top, thickness control device 3 is positioned at the inner lower cartridge corresponding with fluting 7 of finger sleeve 1, spring 5 is placed in spring fitting device 2, one is fixedly connected with finger sleeve 1, other end is fixed on blade pusher 4, the outstanding part in blade pusher 4 bottoms is stuck in spring fitting device 2, blade 6 is equipped with in described blade pusher 4 belows, whole blade pusher 4 and blade 5 can be up and down with spring 5.
Described finger tip skin standard wound cuts device preferably, and the finger sleeve is hollow cylinder.
Described finger tip skin standard wound cuts device preferably, and described spring fitting device is square, and 2 springs are installed in the inside.
Described finger tip skin standard wound cuts device preferably, described thickness control device capable of regulating institute incised wound thickness.
Described finger tip skin standard wound cuts device preferably, and described blade can be changed.
Described finger tip skin standard wound cuts device preferably, the finger sleeve inner corresponding with blade under make plane.
Described finger tip skin standard wound cuts device preferably, and both sides, finger tip position tube wall has ridge, and the distance between the projection of both sides is wider than cutting knife.
Described finger tip skin standard wound cuts device finger sleeve inner and can be different-diameter or size.
The blade placing direction that described finger tip skin standard wound cuts device can be horizontal or vertical.
The blade pusher that described finger tip skin standard wound cuts device can be designed to trigger mechanism as required.
The standard wound that described finger tip skin standard wound cuts device can be designed to different sizes values as required.
Described finger tip skin standard wound cuts device can add pressure control device or other control systems on the finger sleeve.
Described finger tip skin standard wound cuts device can use the material polyethylene, can disposablely use.
Described finger tip skin standard wound cuts device can use material metal, can be repeatedly used.
During use, the experimenter puts into the finger sleeve by the finger of primate, when fingernail is encountered thickness control device, stop, the had projection of both sides, finger tip position tube wall is to help fixed finger, and while making cutting knife cut, the soft tissue of finger tip does not extend out.At this moment point in sleeve relatively fixingly, the experimenter presses blade pusher, and the skin that is exposed to the outer fingertip end part of fingernail namely is cut open, and forms the wound of a normal size.After finger is exited, the hemorrhage time to blood coagulation of finger tip wound is measured.
The invention has the advantages that: this device can be fixed easily and effectively to the finger of primate, and the incision of skin process is quick, easy, and wound is smooth and big or small controlled and accurate, and the safety in energy Protection personnel experimental implementation process.
