Problems solved by technology

[0004] Although the animal models of different contraction modes of limb skeletal muscles have been developed relatively maturely, which can often be realized by loading equipment, however, for the establishment of the contraction model of masticatory muscles, due to the different sources of muscle tissue development, muscle fiber types, and composition, as well as the unique anatomy of the cranio-maxillofacial The influence of structure on the contraction mode of masticatory muscles cannot be summarized simply by the contraction mechanism of limb muscle fibers, and there is no special experimental device to establish animal muscle contraction models of masticatory muscles, and the special structure of masticatory muscles cannot pass through the existing limbs. Muscle modeling device to achieve

Embodiment 1

[0048] Such as figure 1 As shown, the isometric contraction force device includes a supporting part and a fixing device, the supporting part is composed of a connecting part, a sleeve 5 and an inner rod 7, and the inner rod 7 is nested inside the sleeve 5, so The connecting part is fixed on the outer side of the sleeve 5, and the fixing device is connected with the inner rod 7 of the supporting part. The fixing part fixes the inner rod 7 and the object to be connected. The fixing part can be freely selected according to different application tissues. For example, when applied to skeletal muscle, it can be a bone nail, and a hanging ring is set on the inner rod 7 After the bone nail is penetrated, the inner rod and the muscle tissue can be fixed, and the connecting part at the other end can also be fixed and connected with the muscle tissue to promote the rehabilitation and growth of skeletal muscle; when applied to smooth muscle, the Take the intestinal tract as an example, t...

Embodiment 2

[0050] Such as figure 2 , Figure 4 , Figure 5 As shown, the experimental model of isometric contraction of the rabbit masticatory muscles includes a pair of supporting parts and a fixed collar 9, and the supporting parts are made of stainless steel screws 1, connecting parts, sleeves 5 and inner rods. 7, the length of the inner rod 7 is less than the length of the sleeve 5, the inner diameter of the sleeve 5 is 1.4 mm, and the outer diameter of the inner rod 7 is 1.2 mm, so as to avoid too much difference in diameter between the inner rod 7 and the sleeve 5 after nesting Cause the inner rod 7 to shake left and right in the casing 5, wherein,

[0051] The connecting part is composed of a fixing plate 2 and a first hook 3, the first hook 3 is vertically fixed to the fixing plate 2, the fixing plate 2 is also provided with a through hole for setting the screw 1, and the screw 1 is vertically fixed to the connecting part through the through hole to play a retaining role. The...

Abstract

The invention provides an isometric contraction force-applying device which comprises a supporting component and a fixing device. The supporting component is composed of a connecting component, a sleeve and an inner rod. The inner rod is embedded inside the sleeve. The connecting component is fixed to the outer side of the sleeve. The fixing device is connected with the inner rod of the supporting component. The isometric contraction force-applying device is small in size, simple in structure and wide in application range; due to the ingenious design of the sleeve, the isometric contraction force-applying device can be applied to all tissue and organs such as skin, skeletal muscles and smooth muscles; isometric contraction of the tissue and organs is achieved through the ingenious design, and an applicable tool is provided for controlled growth of all the tissue and organs such as the skin, the skeletal muscles and the smooth muscles.

Description

technical field [0001] The invention relates to a force application device, in particular to an isometric contraction force application device. Background technique [0002] At this stage, the theoretical research on muscle contraction is very extensive. The forms of muscle contraction are mainly divided into three forms: shortening contraction, lengthening contraction and isometric contraction. Systematic research on muscle contraction is beneficial to solve a series of problems related to muscle contraction. disease prevention and treatment issues. [0003] In recent years, the important role of the craniomaxillofacial musculature in the treatment of various malocclusions has been widely recognized by scholars. Regarding the mechanism of craniomaxillofacial muscle remodeling, previous studies focused on the muscle strength and myoelectricity of the masticatory muscles before and after treatment, and less attention was paid to the physiological changes of muscle cell remod...
