Description
BACKGROUND OF THE
Generally, biopsy is a method of taking a part of a tissue from a living body and diagnosing it by histopathologically examining it, and it is also called a biopsy.
A biopsy is usually performed when a nodule or a mass in the body is suspected of cancer. In this case, a minimally invasive imaging technique such as ultrasound imaging or CT imaging, rather than a surgical biopsy, Biopsy has been performed recently.
Image - guided biopsy can be divided into aspiration biopsy to obtain only cells and core biopsy to obtain more tissue. Biopsy needle for biopsy has core biopsy needle and aspiration biopsy needle according to biopsy method.
In the course of conventional CT image-guided biopsy, first, an image of a region of interest is obtained through a photographing process for performing a CT scan on a subject to be biopsied, and then a biopsy needle And a needle is inserted into the needle insertion position indicated in accordance with the treatment plan, and then a CT scan is performed. When it is confirmed that the needle has reached the target, a suction gun or a syringe Thereby obtaining a tissue.
In the needle insertion process, the procedure assistant informs the operator of the direction angle of the needle using a goniometer, and inserts the needle in the most accurate position and direction. In such a needle insertion process, since the angle of the needle changes, There is one case, and there is also a disadvantage that an assistant must be present and the biopsy is not possible with the practitioner alone.
Therefore, a technique for solving the problems caused by the conventional needle insertion process is disclosed in Japanese Patent Publication No. 1511299.
The above-described patent document No. 1511299 discloses a biopsy needle guide device that guides a line guide beam to a biopsy object placed on a table so that a biopsy needle aligns with an object to be biopsy Wherein the guide module is configured to guide a linear guide beam to a surface located on a side opposite to the guide module with respect to the table so as to form a linear guide beam on a side of the biopsy needle when the biopsy needle is aligned at an entry angle A guide module positioned relative to the table; And a transfer module for adjusting the position of the guide module.
The conventional biopsy needle guide device as described above is intended to visually guide the approach angle of the needle through the beam. In the course of the needle entry by the practitioner, there is still room for error due to the position, skill, .
The conventional biopsy needle guide device configured as described above has a difficulty in handling and complicated structure due to the provision of a feed module and a power supply for positioning the guide module, leading to an increase in manufacturing cost and an increase in the cost of medical treatment due to an increase in the number of parts And the position of the beam is set differently each time depending on the body shape of the patient, so that the setting time is long.
Therefore, there is a need for research and development of a device that can solve the problem of generating an error in the needle entry process and that can be handled at a lower cost and more easily.
It is an object of the present invention to provide a needle guide apparatus for inspection of a tissue which is simple in structure and easy to handle and which can minimize flow when a needle is inserted.
The present invention provides a needle guide device for tissue inspection comprising a body having a hole formed at its center through which a needle hole is passed, a leveling instrument provided on one side of the body, a needle guide groove for guiding movement of the needle for tissue inspection, A guide member formed to extend across the guide shaft and protruding from a center shaft which is assembled to the yoke at the rear side, and an angle setting unit installed to set the rotation angle of the guide member at a predetermined angle.
At least one of the body and the guide member is formed with an angle display unit for displaying a rotation angle of the guide member.
The leveling system consists of a water leveling system.
The angle setting portion includes a male screw formed on an outer peripheral surface of a central axis of the guide member, and a nut coupled to the male screw and closely contacting or disengaging the body from the guide member.
Wherein the angle setting portion includes a first friction surface formed by alternately arranging grooves and projections along the periphery of the shaft of the body and a second friction surface formed symmetrically with the first friction surface on the guide member It is also possible to include it.
The grooves and the protrusions formed on the first friction surface and the second friction surface are formed in a triangular shape.
Further, the present invention may further comprise a needle support for holding the needle for tissue inspection inserted into the needle guide groove.
According to the needle inspection apparatus for tissue inspection according to the embodiment of the present invention, it is possible to insert the needle at an accurate angle and to minimize the flow of the needle, thereby minimizing the need for repeated insertion of the needle, It is possible to shorten the inspection time and improve the satisfaction of the subject to be examined.
In addition, according to the needle guide apparatus for tissue inspection according to the embodiment of the present invention, since the manipulation such as angle adjustment is simple, easy and compact, it is possible to shorten inspection time, improve portability, and reduce the purchase cost.
