Embodiment Construction
[0034] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0035] Such as figure 1 As shown, the present invention provides a jaw device, which can be applied to a clamping device for clamping electrode needles, especially for the clamping of cylindrical electrode needles. For the clamping member composed of different clamping parts, the angle between the intersection point of the clamping parts of different radians and the line connecting the center of the arc is greater than 60 degrees and less than 180 degrees, and the centers of the clamping parts of different radians are evenly distributed On the arc with the pivot as the center of the circle, therefore, when using the jaw device to clamp the component, each surface of the component can fit the arc surface of the clam...

The invention relates to a jaw apparatus for an acupuncture electrode wire, and a clamping device using the jaw apparatus. The jaw apparatus includes a pair of opposite first jaw member and second jaw member, wherein the first jaw member and the second jaw member are connected through a pivot; both the first jaw member and the second jaw member include successively connected first arc clamping part and second arc clamping part; and an included angle between the intersection point of the first arc clamping part and the second arc clamping part and a center connecting line where the two arcs are is greater than 60DEG and is less than 180DEG. The clamping device includes the above jaw apparatus, so that when a clamping member is a cylindrical member, each surface of the member can be tangent to the cambered surfaces of the clamping parts, thus realizing clamping with maximum strength and highest reliability, and greatly improving reliability and stability of clamping.
Description
technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a jaw device and a clamping device using the jaw device. Background technique [0002] The structure of the clamping device of existing acupuncture needles, such as Figure 4 , including a first clamping piece 6 and a second clamping piece 5, the clamping parts of the first clamping piece and the second clamping piece are set as wavy teeth, which are only suitable for clamping thin sheet objects, especially for clamping Acupuncture needles holding cylinder-shaped members have small and few clamping points, unstable clamping, asymmetry, and unreliability, and clamping is easy to loosen, shake, and fall off easily, which affects the effect of acupuncture and moxibustion. [0003] At the same time, a handle 7 is provided on the first clamping part 6. When the first clamping part 6 and the second clamping part 5 are in a closed state, a barb-shaped gap 8 is formed on the ...
