Figure 7 is a cross-sectional view showing another example of use of pen-type ultrasound cell suction and central biopsy combined biopsy according to an embodiment of the present invention.

As illustrated in FIG. 7, the pen-type ultrasound cell suction and central biopsy combined tissue tester 100 according to an embodiment of the present invention further includes a rotation guide unit 220 that is replaced with the linear guide unit 130. can do.

The rotation guide unit 220 is installed to be rotatable in front of the sliding unit 120 by being replaced with a straight guide unit 130 detachably coupled by a method such as fitting to the front of the sliding unit 120, the syringe 140 is mounted, the rotation guide portion 221 forming a spiral on the outer circumferential surface is formed in the form of a spiral protrusion, for example, is coupled to the guide means 150, so that when moving back and forth to rotate with the syringe 140.

On the other hand, the syringe 140 may be a screw portion 145 having a screw shape on the needle 142 to increase the efficiency of the collection of tissue or cells when rotating with the rotation guide unit 220.

In addition, the guide means 150 is coupled to the rotation guide portion 221 by the pressing of the head 160 or by the elastic force of the elastic members 211 and 212 to guide the rotation guide unit 220 to rotate when moving back and forth, the body ( Guide protrusion 151, such as a ball provided along the inner circumferential surface of the 110, and may further include a rotary ring 152, the rotary ring 152 is rotatable on the outer peripheral surface of the body (110) A plurality of protrusions 153 are coupled to the inner circumferential surface to be coupled to the rotation guide part 221, and may guide the front and rear movement of the rotation guide unit 220 according to the rotation direction. Here, rotating ring 152 can be coupled being provided on the side which is split in the body 110, so as to be rotated in the both ends of which the nutrient release suppressing state on both sides of the body 110.

The operation of the pen-type ultrasonic microneedle cell and tissue tester according to the present invention will be described.

As shown in FIG. 5, the head 160 is pulled out of the body 110 by turning the head 160 from the sliding part 120, whereby the number of times the head 160 is turned or the sliding part 120 is rotated. The display portion 161 (shown in FIG. 2) appears on the display sphere 113 (shown in FIG. 2) by the distance traveled from.

In addition, as shown in FIG. 3 without the head 160 being pushed, the needle 142 of the syringe 140 may be aligned with the end line of the cap 114, and the sliding part may be pushed by pushing the head 160. When the 120 is advanced, for example, 10 mm, the needle 142 of the syringe 140 protrudes 10 mm from the needle passage hole 111. At this time, when the linear guide unit 130 is guided by the guide unit 150, specifically, the guide protrusion 151 to push the head 160, the linear guide unit 130 is provided via the sliding unit 120. The linear movement with the syringe 140 so that rotation is suppressed. This minimizes tissue damage when the needle 142 enters the lesion site.

When the hand is released from the head 160, the needle 142 may be stopped by the rotary knock module 180 in a state of protruding by 10 mm. Accordingly, when the needle 142 is removed from the head 160 in the stationary state when the needle 142 is inserted into the lesion site, the needle 142 stops in the protruding state so that the finger is less tired, and the ultrasound image is stopped in the stationary state. The entry into the lesion site can be confirmed again. At this time, the wire 173 is released from the pulley 172 so that the syringe 140 is advanced without any pressure change therein.

And, as shown in Figure 6, press the head 160 to proceed further 10mm, the end of the needle 142 exactly enters the lesion site, by pressing the button 171 using the third or fourth finger By moving the piston 143 backward, a negative pressure is generated in the syringe 140, and the negative pressure of the syringe 140 enables the collection of cells and tissues to the lesion site.

On the other hand, if the negative pressure is continuously applied to the syringe 140, the blood is sucked too much, which interferes with the cell reading, thereby minimizing blood intake, and when the finger is released from the button 171 to operate only when necessary, the return spring 175 (Fig. 4). The pulley 172 is returned to its original position by the elastic force shown in FIG.

In addition, when the front end portion 117 of the body 110 is removed and the linear guide unit 130 is replaced with the rotation guide unit 220, by pressing the head 160 to rotate through the sliding unit 120 as a medium. When the guide unit 220 is moved forward by the guide protrusion 151 of the guide means 150, the rotary guide unit 220 is rotated with the syringe 140, which causes the needle 142 or cells inside the lesion Maximize tissue harvesting.

On the other hand, when the syringe 140 is mounted on the linear guide unit 130 or the rotary guide unit 220, using the needle 142 having a cutting groove 144 or a needle having a screw portion 145 according to the lesion site 142 may be used. The tissue collecting needle 142 is inside the smooth guide needle 116 in order to minimize tissue damage until the lesion is reached, after reaching the lesion, the head 160 having a depth control function By pressing it is inserted into the lesion at a defined depth and tissue is collected. In this case, the needle 142 having the cutting groove 144 reciprocates linear motion with the linear guide unit 130 for efficient tissue collection, and the needle 142 having the screw portion 145 is the rotary guide unit 220. To reciprocate the rotary motion. Here, the guide needle 116 is inserted into the actual body to be near the lesion site, and inserted into the vicinity of the lesion is inserted into the lesion is a cutting needle 142 or a tissue picking needle 142 with a screw unit 145 is inserted. . After the tissue collection is completed, the needle 142 enters the guide needle 116 again and pulls the guide needle 116 out of the body in the inserted state to minimize tissue damage.

In addition, replacement of the cap 114 with the guide needle 116 enables hygienic use. On the other hand, the lid 190 may be mounted to the front end of the body 110 in a state in which the cap 114 and the syringe 140 is separated.

According to the pen-type ultrasound cell suction and central biopsy combined biopsy device according to the present invention, not only easy to operate and carry, but also to accurately collect the cells or tissues on the lesion site, the linear movement of the syringe and In addition to easily changing the rotational movement, it is possible to easily select the needle shape of the syringe, it is possible to increase the efficiency of the collection according to the cell or tissue for the lesion site.

To this end, under the ultrasound, the depth and shape of the lesion can be accurately determined, and cell aspiration and central biopsy can be performed at the same time, and the depth of the lesion can be adjusted to maximize stability. This makes it possible to harvest enough tissues and cells simply and easily while maximizing stability with minimal invasion of the lesion site.

Although the present invention has been described with reference to the accompanying drawings, it is to be understood that various changes and modifications may be made without departing from the spirit of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the following claims.
