Description
Technical field
The utility model belongs to medical puncture needle apparatus field.
Background technique
In the medical field, for example, taken to be made a definite diagnosis lesion anthropolith tissue or cell,
Or when accurately finding nerve, use puncture needle (biopsy needle, insulated electrode injection needle).At this time, it may be necessary to correctly hold
The position of the position of puncture needle, especially front end, thus diagnostic ultrasound equipment, such as biopsy needle are used, on one side in image
Lower ultrasonic echo of the confirmation from puncture needle front end is punctured on one side, correctly holds the portion of harvesting of tissue of puncture needle front end
Whether (needle point or notch section) reaches lesion.
But there is delay on a display screen in ultrasonic imaging, so bad grasp inserting needle amount when artificial puncture, is easy to wear
It pierces and too deep unnecessary pain is caused to patient.
Utility model content
The purpose of this utility model is to provide a kind of puncture needle holder with a scale, with solve the prior art cannot grasp into
The problem of needle amount.
In order to achieve the above object, the base case of the utility model provides a kind of puncture needle holder with a scale, including needle
Frame and guiding mechanism, guiding mechanism include upper leading truck, lower leading truck, the first friction roller and the second friction roller, and punch block is fixed to be connected
It connects on lower leading truck, upper leading truck is slidably connected with lower leading truck；First friction roller and the second friction roller are rotatablely connected respectively
On upper leading truck and lower leading truck, the first friction roller and the second friction roller are oppositely arranged, and upper leading truck is equipped with limit hole, the
Two friction wheel ends are fixedly connected with scale band, and scale band passes through the limit hole on upper saddle, is removably connected on scale band
Size is greater than the locating part of limit hole.
The principle of this base case is: when puncture needle moves between the first friction roller and the second friction roller, driving the
Scale band is wrapped in the end of the second friction roller by one friction roller and the rotation of the second friction roller, the second friction roller when rotating.Scale
The locating part taken moves, and when locating part encounters limit hole, locating part is moved down with upper leading truck.Second friction
Roller continues to rotate, and scale band continues to reduce the distance between the first friction roller and the second friction roller toward drop-down upper leading truck,
And then clamp puncture needle, prevent puncture needle from moving forward again.
The beneficial effect of this base case is: the present apparatus can observe puncture needle into intracorporal length by scale band
Degree.And can the volitional check inserting needle amount of puncture needle, to prevent inserting needle too deep bring unnecessary pain to patient.Separately
Outside, present apparatus structure is simple, and fast response time is easy to operate.
One: the first friction roller of prioritization scheme and the second friction roller are equipped with abrasive grain.The setting of abrasive grain increase friction roller with
Frictional force between puncture needle.
Prioritization scheme two: the abrasive grain is made of rubber.On the one hand rubber abrasive grain provides biggish frictional force, on the one hand
Prevent abrasive grain from causing to damage to wire surface is punctured.
Prioritization scheme three: the locating part is equipped with threaded hole, is equipped with puller bolt in threaded hole.The setting of puller bolt
Facilitate the position for adjusting locating part, and then achievees the purpose that adjust inserting needle amount.
Prioritization scheme four: further including third friction roller and the 4th friction roller, and third friction roller and the 4th friction roller turn respectively
It is dynamic to be connected on saddle and lower saddle.The setting of third friction roller and the 4th friction roller provides bigger for compression puncture needle
Frictional force keeps the present apparatus more reliable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment puncture needle holder with a scale.
Specific embodiment
The utility model is described in further detail below by specific embodiment:
Appended drawing reference in Figure of description includes: the second friction roller 1, puncture needle 2, scale band 3, the first friction roller 4, limit
Position part 5, limit hole 6, third friction roller 7, the 4th friction roller 8, upper leading truck 9, punch block 10, lower leading truck 11.
Embodiment: the puncture needle holder with a scale in this programme, including punch block 10 and guiding mechanism, guiding mechanism include upper
Leading truck 9, lower leading truck 11, the first friction roller 4, the second friction roller 1, third friction roller 7 and the 4th friction roller 8.Punch block 10 is in
2 guide sleeve of puncture needle of shell-like, 10 portion integral of punch block are molded over lower 11 top of leading truck.On upper leading truck 9 integrally formed with
Vertical sliding pin, integrally formed with sliding eye on lower leading truck 11.Upper leading truck 9 passes through sliding pin and cunning with lower leading truck 11
Dynamic hole is slidably connected.
First friction roller 4 and the second friction roller 1 are rotatably connected on upper leading truck 9 and lower leading truck 11 by axle sleeve respectively
Rotation hole in.Third friction roller 7 and the 4th friction roller 8 are rotatably connected on upper leading truck 9 and lower leading truck by axle sleeve respectively
In rotation hole on 11.First friction roller 4 and the second friction roller 1 are oppositely arranged, and third friction roller 7 and the 4th friction roller 8 are opposite
Setting.If the first friction roller 4, the second friction roller 1, third friction roller 7 and the 4th friction roller 8 Surface microwave be welded with dry rubber substance
Abrasive grain.
Integrally formed with limit hole 6 on upper leading truck 9, the second friction wheel end bind has scale band 3, and scale band 3 passes through
Limit hole 6 on upper saddle.Locating part 5 is in shaft-like, integrally formed with threaded hole on locating part 5, is threaded in threaded hole
Puller bolt, scale band 3 pass through threaded hole.
In use, puncture needle 2 is between the first friction roller 4 and the second friction roller 1, third friction roller 7 and the 4th friction roller 8
