Cutting device for standard wound of fingertip skin of primate

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 [0001] The invention belongs to the field of biomedical devices, in particular to a standard incision tool for primate fingertip skin. Background technique [0002] Bleeding time is a commonly used index in clinical and animal experiments, and is used to evaluate the body's coagulation function, related diseases, and the effects of anticoagulant and antithrombotic drugs, etc. In the implementation of the measurement of bleeding time in primates (such as humans, monkeys, etc.), generally a standard incision is made in the skin of the arm of the upper limb to measure the time from bleeding to coagulation. Experiments have proved that skin incision at the tip of the finger is a simple and effective method for determination. Usually, the operator can use one hand to relatively fix the animal's finger on the cutting board, and use the other hand to make the incision with a scalpel. This method of making an incision by hand has many disadvantages, such as: the ski...

AI Technical Summary

Problems solved by technology

This method of making an incision by hand has many disadvantages, such as: the skin slides during the incision, the incision position is not easy to fix and repeat, the cutting force is difficult to control, the size and thickness of the incision are not easy to control, and the finger pulp of primate nails is difficult to control. The spacing is inconsistent, resulting in large errors in the measurement results

At the same time, there is also the risk of accidental injury of the operator when operating with bare hands, and it is easy to cause visual discomfort, etc.
