Description

A collecting device for multiple tissue,

The present invention relates to an apparatus and method for increasing the efficiency of inspection by collecting a plurality of tissues at a time through a plurality of tissue collecting sections through a plurality of connecting members having mutually different lengths.

Biopsy (biopsy) refers to a type of examination in which a hollow needle is inserted into an organ in vivo without cutting the skin, and a portion of the tissue is taken for histopathological examination.

Kidneys, liver, and the like. However, the endoscopes and tissue-sampling devices are then combined to perform organ organs such as the digestive tract, urinary tract, and airways, organs with tubal glands widely.

In histopathologic examination for removing tissue from a patient for examination and treatment of a cell tissue, when a tissue is sampled using a microspike, a tissue sample is minutely invaded. Therefore, a tissue is sampled using a forceps type biopsy tool It can give the patient less pain than the case. At this time, the collected tissue can be formed into a paraffin block through processes such as fixation, dehydration, transparency, paraffin penetration, embedding and the like.

However, in the conventional tissue sampling apparatus, a plurality of procedures must be performed by collecting tissues individually, and the problem of amplifying the burden of the patient over a long period of time is required.

The biopsy is a test to check whether the living body is in a normal state by analyzing a part of the living tissue, and to check whether or not the subject of the tissue is diseased.

When the tissue is collected, the state of the tissue cell is checked through a microscope, and a tissue test is performed by administering a reagent or the like necessary for histological examination to the tissue.

For example, in obstetrics and gynecology endometrial endometrial biopsy is often performed.

In particular, when there is a tumor of the uterine myoma or pelvis, a simple test such as ultrasound, simple abdominal radiography, or both pelvic examination is used to diagnose the tumor.

If the tumor is found in the uterus or the pelvis, it will be examined for cervical or abdominal examination for more accurate diagnosis.

If a bleeding or mass is found in the test result, biopsy is taken to obtain a more precise examination. In order to collect tissue for precise examination, a biopsy is taken through a syringe and an injection needle which can enter the uterus do.

At this time, the lengths of the first connection pipe 110a, the second connection pipe 110b and the third connection pipe 110c exposed to the outside of the tube 200 may be different from each other.

Although not shown in the figure, the first sampling unit 100a, the second sampling unit 100b and the third sampling unit 100c or the first connection pipe 110a, the second connection pipe 110b, and the third connection pipe 110c may further include an auxiliary mechanism which can easily support each other.

5 (a), the first connection pipe 110a is exposed to the outside longer than the second connection pipe 110b and the third connection pipe 110c. As a result, The first sampling unit 100a combined with the first fixing unit 120a includes a second sampling unit 100b coupled with the second fixing unit 120b and a third sampling unit 100b coupled with the third fixing unit 120c. 100c. ≪ / RTI >

Here, the first sampling unit 100a, which is exposed to the outside for a longer time, collects the target tissue through the blind and can be closed, and the first fixing unit 120a As shown in Fig. 5 (b).

At this time, when the first sampling unit 100a falls down, the distal end of the second sampling unit 100b can be protruded forward from the first sampling unit 100a.

Therefore, the second sampling unit 100b can also collect other tissue through the blind and can be in a closed state, and can be separated from the second fixing unit 120b through the operation of the knob 300, (b) of FIG. 5 through the same process as shown in FIG. 5 (c).

In addition, when the second sampling unit 100b falls down, the distal end of the third sampling unit 100c can be protruded forward from the second sampling unit 100c.

Therefore, the third collecting unit 100c can also collect other tissues through the blind and can be in a closed state, and can be separated from the third fixing unit 120c through the operation of the handle 300, 5 (d) through the same process as that of FIG. 5 (b).

Accordingly, the user can acquire a plurality of tissues through the plurality of collecting units 100a, 100b, and 100c, and simultaneously collect the plurality of collecting units 100a, 100b, and 100c.

Also, considering the positions of the plurality of sampling units 100a, 100b, and 100c spaced downward, it is possible to easily distinguish the tissue collected at any site.

In the meantime, in the present invention, a concrete embodiment has been described on the assumption that there are two harvesting units and three harvesting units. However, such a configuration is merely one example for applying the present invention, It is obvious that a configuration using a plurality of sampling units 100 can be used.

When the above-described configuration of the present invention is applied, it is possible to increase the inspection efficiency by collecting a plurality of tissues at a time through a plurality of tissue collecting sections through a plurality of connecting members having mutually different lengths.

In addition, since the exposed positions of the plurality of sampling units apart from each other are different from each other, it is possible to easily distinguish the collected tissue from any site.
