Description

TECHNICAL FIELD [0001] The present invention relates to a syringe control device for fine needle inspection,

The present invention relates to a needle control apparatus for fine needle inspection, and more particularly, to a needle control apparatus for fine needle inspection that moves a piston of a needle in a needle examination to inhale and extract body tissue through a vacuum pressure of the needle.

Typically, the fine needle (aspiration) test is a test to diagnose the presence of a disease by sucking cells through a syringe, making an important contribution to the early diagnosis of malignant tumors, mainly performed in the thyroid and breast.

This fine needle test inspects the cells of the syringe by inserting the needle of the syringe into the lesion of the syringe and sucking the cells of the lesion through the vacuum of the syringe or moving the coarse needle back and forth within the lesion.

The diagnosis of thyroid carcinoma is based on the fact that the number of cells to be aspirated is important, and whether or not the aspirated cells are exactly aspirated from the tumor plays an important role. Especially, And the metastatic lymph nodes are most likely to be aspirated. In addition, accurate targeting of the tumor is a very important process because of the existence of the body organs around the thyroid that can cause fatal problems in the airways, nerves, and vascular structures (carotid, jugular vein) can do.

However, when performing the fine needle inspection, the practitioner must hold the probe of the ultrasound examiner with one hand while checking the position of the procedure, and manipulate the syringe with the other hand, which is not only inconvenient but also the operation of the syringe is unstable, There is a risk of misinformation due to difficulty in targeting, damage of nearby important organs may occur, and there is a troublesome problem that an assistant for holding the probe of the ultrasonic scanner must be present.

On the other hand, the prior art prior to the present invention is a cytological examination inhaler proposed in Korean Utility Model Registration No. 20-0443099.

The inhaler of the prior art consists of a syringe holder to which a cylinder of the syringe is fixed and a pulling bundle having a handle and a piston fixing part. The piston of the syringe is retracted while pulling the pulling bundle and the handle through the grip of the operator, .

This prior art inhaler is advantageous in that the operator can control the ultrasonic probe with the other hand by allowing the syringe to be operated with one hand.

However, since the inhaler of the prior art pulls the pull bundle through the grip of the operator to move the piston of the syringe, the hand swings while pulling the pull bundle, so that the injection needle swings and stable inhaling of the lesion tissue is performed And can cause fatal complications in patients due to the induction of peripheral tissue damage due to shaking of the needles.

As another prior art, there is an extractor for extracting a bio-texture, which is proposed in Korean Utility Model Publication No. 20-2012-0006364, but this is also a technique of moving the cylinder rod through the hands of a practitioner, which is unstable.

Korean Utility Model Registration No. 20-0443099 Korean Utility Model Publication No. Hei 20-2012-0006364

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art as described above, and it is an object of the present invention to provide a syringe which can easily control a syringe by one hand of a practitioner, The present invention has been made to solve the above problems, and it is an object of the present invention to provide a syringe control device for a fine needle test capable of stably extracting a lesion tissue without swaying the syringe.

In accordance with another aspect of the present invention, there is provided a syringe control device for fine needle inspection comprising: a syringe of a fine needle inspection device; a suction needle for sucking the body tissue through a needle of the syringe; Wherein the cylinder of the syringe is fixed in a detachably mounted state and has a drawing space for drawing the piston of the syringe from the cylinder; And a piston driver provided in the housing to draw the piston from the cylinder or draw the piston into the cylinder while providing a driving force to the piston.

For example, the piston driver includes a piston holder movably provided in a lead-out space of the housing and detachably coupled to an end of the piston; A drive motor to which the housing is fixed to provide a rotational force; And a transfer mechanism for transferring the rotational force of the drive motor to the piston holder and moving the piston holder back and forth in accordance with the drive of the drive motor.

For example, the transfer may include: a male screw protruding in the longitudinal direction of the piston while being identical with the piston holder; And a female screw threadedly coupled to the male screw in a state of being connected to a rotary shaft of the drive motor, to rotate the male screw back and forth by the drive motor.

Alternatively, the transfer may include, for example, a rack gear formed along the longitudinal direction of the piston holder; And a pinion gear rotated by the driving motor in a state of being engaged with the rack gear.

The piston driver may further include a slider slidably coupling the piston holder to the housing and guiding the piston holder forward and backward according to the operation of the transfer.

For example, the slider includes a guide rail formed in a groove shape along a side wall of the drawing space formed in the housing; And a guide protrusion protruding from the piston holder and moving in a state sandwiched by the guide rail.

For example, the housing includes a housing main body in which a cylinder slot is formed in a groove shape in which the cylinder is inserted, the housing space in which the pullout space is formed at one side of the cylinder slot, and the piston actuator is installed; And a housing cover which is openably and closably coupled to the housing main body.

The housing may further include an adapter provided according to the size of the cylinder and coupled to the cylinder and engaged with the cylinder while being coupled with the cylinder to couple the cylinder to the cylinder slot. .

In addition, since accurate needle aspiration due to the shaking of the injection needle caused by fine needle aspiration of the tumor is prevented, it is possible to accurately target the injection needle, thereby improving the reliability of the examination.

Specifically, since the piston holder coupled to the end of the piston is moved forward and backward by the rotational force of the drive motor transmitted through the transfer, the piston can automatically move through the mechanical configuration.

Further, as the movement of the piston holder is guided by the slider, the piston of the syringe can move more stably.

In addition, since the cylinder of the syringe is fitted into the cylinder slot of the housing by the adapter, the syringe can be mounted on the housing, regardless of the size of the cylinder.
