In the present embodiment, fluted 31 are set on graduated scale 3, accommodates and is provided with position and groove on the inner surface of pipe 2
Tongue corresponding to 31, a track that can be relatively moved is formed, while graduated scale convenient telescopic moving is ensured,
Effectively lock it not rotate in the axial direction, be convenient for measuring and calibrate.In the present embodiment, only set in the side of graduated scale 3
A groove 31 is put, one corresponding tongue is set in the inner side for accommodating pipe 2, but the invention is not restricted to this, in other embodiment
In, one tongue can also be set in the side of graduated scale 3, correspondingly, one corresponding groove is set in the inner side for accommodating pipe 2
31.In addition, the quantity in groove 31 and tongue is also not necessarily limited to one group, can be two groups or more.
In the present embodiment, limited location obstruction piece 7 is set on graduated scale 3, spacing obstruction piece 7 include continuous convex portion with it is recessed
Portion, form position limiting structure, can limit the relative movement accommodated between pipe 2 and graduated scale 3, two adjacent convex portions or recess it
Between spacing distance it is equal.But the invention is not restricted to this, spacing obstruction piece 7 can also be laciniation, or have dipping and heaving
The structure of shape, etc..
Further, in the present embodiment, the spacing distance between two adjacent convex portions or recess is 1 millimeter, or
Spacing distance of the spacing distance between 1 millimeter, or each group of relief fabric between adjacent sawtooth is 1 millimeter.Meanwhile
Scale unit on graduated scale 3 is also 1 millimeter, in this case, a recess or convex portion is often moved, equivalent on graduated scale
Corresponding least unit size, which thereby enhances the convenience accurately measured.But the invention is not restricted to this, in other embodiment
In, spacing distance can be adjusted flexibly as needed, as long as example, spacing distance between two adjacent recesses or convex portion with
Least unit on graduated scale is identical, etc..
In the present embodiment, the inner side for accommodating pipe 2 is provided with the position fastener corresponding with spacing obstruction piece 7, and fastener is used
Screens is carried out in the position limiting structure formed to spacing obstruction piece 7.More specifically, when receiving pipe 2 moves along graduated scale 3
When, the continuous recess in spacing obstruction piece 7 moves with convex portion on fastener, and fastener produces screens effect to it, operator's
During thrust increase, relative movement is produced, when thrust is decreased below fastener to the clamping resistance of position limiting structure, stops relative moving
It is dynamic.Thus, the movement of receiving pipe 2 is more easily carried out fine control and adjustment, prevent accommodate pipe 2 along graduated scale 3 with
Meaning ground is mobile, influences the accuracy of measurement.This screens is designed to make more easily to position, adjust and survey in measurement process
Amount, so as to reduce number of degrees error.
In the present embodiment, the outside for accommodating pipe 2 is provided with locked component 6, for accommodating pipe 2 relative to graduated scale 3
Position locked.
In particular, locking key 6 includes neck 62 and position on ＆ off switch 61 corresponding with neck 62, wherein, neck
62 include locked；On ＆ off switch 61 locks in latched position and graduated scale 3, in unlocked position and graduated scale 3
Unblock.
In the present embodiment, one end of graduated scale 3 includes the first male member 5, and the one end for accommodating pipe 2 includes the second male member 4, and
And first male member 5 and the second male member 4 form 2 structures, for measurement distance.Further, in the present embodiment, second is convex
Part 5 is 2.5 millimeters relative to the protrusion distance of graduated scale 3, suitable for the measuring environment of arthroscope.But the invention is not restricted to this,
In other embodiments, protrusion distance can be adjusted flexibly as needed.Due to the setting of 2 structures, make measurement more straight
See, more convenient, measurement result is also more accurate.

When holding handle 1, thumb is just supported in position-regulation portion 9.In this case, by handle and position conciliation portion 9
Mutual alignment structure, while by the relatively slidable structure accommodated between pipe 2 and graduated scale 3 of slide rule component 8, Ke Yifang
Just by the motion of thumb, one-handed performance is realized,
Further, in the present embodiment, position-regulation portion 9 is recess, is offseted for the thumb with operator
Effect.But the invention is not restricted to this, and in other embodiments, position conciliation portion 9 can also be a protuberance, or a table
The larger position of face coefficient of friction, as long as the effect to offset can be produced with operator's thumb, enable thumb smooth
Ground regulation accommodates the relative movement between pipe 2 and graduated scale 3.
In the present embodiment, handle 1 is the plastic cylinder of a diameter of 20-30 millimeters, and one end connects with slide rule component 8
Connect, the other end is in circular arc, and this handle design is advantageous to one-handed performance.
In the present embodiment, the scale unit on graduated scale 3 be 1 millimeter, the scale unit just with spacing obstruction piece 7
Adjacent recess or convex portion spacing distance it is equal, in this case, advantageously in operator to accommodate pipe 2 enter line slip
While it is easily spacing, improve the precision of measurement.But the invention is not restricted to this, and in other embodiments, scale unit can be with
Flexibly set as needed, correspondingly, the spacing distance between adjacent recess or convex portion in spacing obstruction piece 7 is also correspondingly
It is configured.Certainly, in other embodiments, above-mentioned recess and the spacing distance of convex portion can also more be flexibly set, example
Such as, it is 2 times of scale unit of graduated scale 3, or other, slide spacing effect as long as can realize.
In the present embodiment, the length of graduated scale 3 is 120-150 millimeters, preferably 136 millimeters, in such case
Under, effective measured value, i.e. maximum effectively scale value is 50 millimeters.Correspondingly, the length for accommodating pipe 2 is 75-85 millimeters, preferably
Be 80 millimeters, correspondingly, arthroscope measuring scale entire length is 230-240 millimeters, it is preferred that 236 millimeters.
The advantages of above-mentioned embodiment, is as follows：
1. error is small, the degree of accuracy is high.
2. intra-articular distance between two points can be measured accurately, accurate judgement is provided for operative doctor, reduces operation error.
3. one-handed performance, easy to operate can be realized.
It is 4. simple in construction, easily fabricated, manufacturing cost is low.
Working process and principle
According to the present invention, the handle 1 to interfix and graduated scale 3, receiving pipe 2 and graduated scale 3, the Yi Jishe of relative movement
Put on accommodating pipe 2 for operator's gripping handle 1 when thumb the position conciliation portion 9 of the point of application is provided, structure in conjunction with each other
Into a kind of degree of accuracy height and it is capable of the arthroscope measuring scale of one-handed performance.Further, spacing obstruction piece 7 and fastener shape are passed through
Into screens effect, the spacing distance between two adjacent recesses or convex portion is identical with the least unit on graduated scale, makes survey
Scale can be more easily adjusted, positions and determined during amount.Further, when operator's gripping handle 1, it is arranged on
Accommodating the position conciliation portion 9 on pipe 2, exactly thumb provides impetus, so as to conveniently by one-handed performance, adjust
Section accommodates position of the pipe 2 relative to graduated scale 3, easy to operate.
