Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Wherein like reference numerals refer to like parts throughout.

Example 1

As shown in fig. 1-4, the utility model provides a make things convenient for root canal therapy syringe of measurement, including syringe 1 and K file 2, syringe 1 mid-mounting has holds grip block 3, the mid-mounting of holding grip block 3 has needle tubing 4, handle 5 is installed to K file 2's bottom, K file 2's upside movable mounting has indicator plate 6, handle 5's bottom is provided with hole 7, surface one side of needle tubing 4 is provided with volume scale mark 8, the surface opposite side of needle tubing 4 is provided with length scale mark 9, hold grip block 3's surface one end and install and place recess 10, the both sides of placing recess 10 are provided with spout 11, spout 11 internally mounted has clip 12, the inboard of clip 12 is provided with slide rail 13, expanding spring 14 is installed to one side of slide rail 13.

Further, the slide rail 13 of spout 11 and clip 12 inboard is sliding connection, and spout 11 is the setting of protruding type structure, and its top surface inboard is provided with anti-drop buckle groove, and the number of spout 11 is two, and sets up for central symmetry, makes clip 12 slide from top to bottom through slide rail 13 in spout 11 inboard to through the fixed position of hole 7, make K file 2 and needle tubing 4 can keep the parallel state convenient observation.

Placing recess 10 and being circular groove structure, placing recess 10 and K file 2 and being connected for inlaying, making clip 12 behind the horizontal position of fixed K file 2, place recess 10 and with K file 2 inlay be connected and can realize the vertical position of fixed K file 2, the person of facilitating the use follows not equidirectional observation.

The clip 12 is a concave half-opening structure, the inner side of the clip 12 is fixedly provided with the extension spring 14, after the clip openings at the two sides of the top end of the clip 12 extend into the inner side of the hole 7, the extension spring 14 at the bottom end enables the clip opening at the top end to generate clamping force due to the elasticity of the extension spring, and therefore the effect of clamping and fixing the K file 2 is achieved.

The clip 12 is made of shape memory metal, the length and width of the cross section of the clip 12 are the same as the diameter of the hole 7, so that the clip 12 can be taken out or put into the chute 11 from the inner side after being bent through the clip opening, and when clamping is required, the clip 12 can be restored to a concave half-opening structure at the top end clip opening at different temperatures, so that the clip 12 can be repeatedly used with different syringes 1, and the effect of reducing garbage output is achieved.

The 0 line sign in bottom of length scale mark 9 is same horizontal plane setting with the top surface of handle 5, makes K file 2 and needle tubing 4 be parallel state after, the user can be simple subtract through the reading K file 2 top reading on the length scale mark 9 and the reading of instruction piece 6, reaches the effect of knowing working length.

The length scale markings 9 are dark red in colour, making the length scale markings 9 more brilliant in colour and able to be distinguished from the volume scale markings 8.

Specifically, after the K file 2 measures the working length, a user can slide the clip 12 in the chute 11, the clip opening through the clip opening 12 is inserted through the hole 7 at the bottom end of the handle 5, because the section length and width of the clip 12 are the same as the diameter of the hole 7, and the clip opening at the top end generates clamping force by matching with the elasticity of the expansion spring 14 at the inner side, thereby achieving the effect of clamping and fixing the K file 2, the semicircular structure at the bottom end of the K file 2 is embedded and placed with the placing groove 3 on the surface of the holding plate 3, thereby fixing the horizontal and vertical positions of the K file 2, at the moment, the length scale lines 9 at one side of the surface of the K file 2 and the needle tube 4 are in a parallel state for convenient observation, and the effect of knowing the working length is achieved by subtracting the reading of the reading number at the top end of the K2 on the length scale lines 9 and the reading number of the indicating sheet 6, and the clip 12 using the shape memory metal can, when the clamping action is required to be produced, the top end clamp opening of the clamp 12 can be reduced to be a concave half-opening structure through different temperatures, the clamp 12 can be repeatedly used with different injectors 1, the effect of reducing garbage output is achieved, the injector 1 breaks the situation that the traditional injector can only be used for liquid measurement, the length of an object can be measured, only an open slot is formed in a holding plate 3, length scale lines 9 are printed on the surface of a needle tube 4, the measurement effect can be achieved through the prefabricated clamp 12 in a matched mode, and the functionality of the injector is expanded while the mold of the injector 1 of an original manufacturer is not influenced.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
