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

[0047] Such as figure 1 As shown, the isotonic contraction force device includes a supporting part and a fixing device, and the supporting part is composed of a connecting part, a sleeve 5, a push spring 10 and an inner rod 7, and the push spring is arranged on the sleeve 5, the inner rod 7 is nested into the sleeve 5, and the push spring 10 provided in the sleeve 5 elastically supports the inner rod 7, and the connecting part is fixed on the outside of the sleeve 5, The fixing means are connected to the inner rod 7 of the support 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...

Embodiment 2

[0049] Such as figure 2 , Figure 4 , Figure 5 As shown, the said rabbit masticatory muscle isotonic contraction experimental model with a force device, including a pair of supporting parts and a fixed collar 9, said supporting parts are made of stainless steel screw 1, connecting parts, casing 5, nickel titanium Push spring 10 and inner rod 7 are formed, and the length of described inner rod 7 is less than the length of casing 5, and the inner diameter of casing 5 is 1.4mm, and the outer diameter of inner rod 7 is 1.2mm, avoids the inner rod 7 and sleeve after nesting. Too much difference in diameter of the tube 5 causes the inner rod 7 to shake left and right in the casing 5, wherein,

[0050] 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 t...

Abstract

The invention provides an isotonic contraction forcing device which comprises a supporting component and a fixing device. The supporting component is composed of a connecting component, a sleeve, a pushing spring and an inner rod, the pushing spring is arranged inside the sleeve, the inner rod is nested into the sleeve, the pushing spring arranged in the sleeve has the elastic supporting effect on the inner rod, the supporting component is fixed on the outer side of the sleeve, and the fixing device is connected with the inner rod of the supporting component; the isotonic contraction forcing device is small in size, simple in structure, wide in application range and capable of being applied to tissues and organs such as skin, skeletal muscles and smooth muscles, isotonic contraction of the tissues and the organs is achieved through ingenious design, and applicable tools are provided for controllable growth of the tissues and the 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 isotonic 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 remode...
