Embodiment Construction

[0025] Fig. 1 is a schematic structural view of the present invention; Fig. 2 is a top view of Fig. 1; Fig. 3 is a right view of Fig. 1; Fig. 4 is an enlarged view of part A in Fig. 1; Fig. 5 is an enlarged view of part B in Fig. 2 .

[0026] as the picture shows:

[0027] The skin stretch fixing frame of this embodiment includes a bracket and a skin stretch fixing assembly. The bracket includes a strut 1 and a strut 2 arranged in parallel. and the fixed rod I3 and the fixed rod II4 between the rod 2; the fixed rod I slides and fits with the rod 1 and the rod 2 along the longitudinal direction of the rod in a lockable manner (of course, the fixed rod I and the fixed rod II are all in the In a lockable manner, it can be slidably matched with the two poles along the longitudinal direction of the pole, or the fixed pole II can be slidably matched with the two poles along the longitudinal direction of the pole in a lockable manner, which can realize the purpose of the present inve...

Abstract

The invention discloses a skin stretching and fixing frame which comprises a bracket and a skin stretching and fixing component, wherein the bracket comprises two supporting rods, and the skin stretching and fixing component comprises a fixing rod I and a fixing rod II; the fixing rod I and / or the fixing rod II are / is in sliding fit with the two supporting rods; and fixing buckles which are in one-to-one correspondence are arranged on the fixing rod I and the fixing rod II. When the skin stretching and fixing frame is used, the skin of an animal model is stretched through the skin fixing buckles, the limbs of the animal model are bound on the bracket through ropes, and the interval between the fixing rod I and the fixing rod II is adjusted by sliding the fixing rod I and / or the fixing rod II, thereby changing the stretching force born by the skin of the animal model; and when the interval reaches the required degree, the fixing rod I and / or the fixing rod II are locked and fixed to keep the skin stretching state stable. The whole device has the advantages of simple structure, easy manufacture and convenient operation, and is suitable for researching and observing the change of biological behaviors such as multiplication rates, growth states and the like of different cells under the condition of different stretching force and pathological and physiological processes and related mechanisms in the healing process of the wound surface of the animal model.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to a skin stretching fixture for observing changes in biological behavior of cells under different tension conditions and wound healing in living bodies under different pressure loads. Background technique [0002] Cell mechanics is one of the foundations of tissue engineering and cell engineering, and one of its most important contents is to study the influence of mechanical stimulation on the change and growth of the cytoskeleton system. The force outside the body, the interaction force (stretch, shear) between various tissues and cells in the body during life movement, and the intracellular tension generated when the cytoskeleton changes, constitute a mechanical system that regulates growth and development and cell differentiation. . Force can regulate cell function by affecting intracellular gene expression and protein synthesis, and plays an important role in the physiological and...
