Embodiment Construction

[0028] Next, preferred embodiments of the biopsy device of the present invention will be described with reference to the drawings.

[0029] refer to Figure 4 to Figure 6 , A biopsy device 100 according to an embodiment of the present invention includes an outer part 10 , an inner part 20 , a rotation drive device 40 , and a cover part 30 .

[0030] The outer member 10 includes a cylindrical outer body portion 11 . A part of the outer member 11 is cut to form a cutout portion 12 so that the inner side and the outer side communicate. When the outer main body part 11 is inserted into the human body, human tissue in contact with the outer surface of the outer main body part 11 can enter the inner side of the outer main body part 11 through the outer incision part 12 .

[0031] One side edge of the outer cutout portion 12 forms an outer blade portion 13 having a sharp blade surface 13a. Such as Figure 7 As shown, the angle θ1 formed by the inner surface of the outer body port...

Abstract

The present invention discloses a biopsy device for insertion into a human body and dissection of tissue. The invention includes an outer member, an inner member and a rotary drive. The outer part has a cylindrical outer body part, a part of the outer body part is cut and formed so that tissues in contact with the outer surface of the body part can enter the inner side of the outer body part, and One side edge is sharply formed at an acute angle, and the cutting blade is provided at the end of the outer main body to cut off human tissue so that the outer main body enters the human body. The inner member has a cylindrical inner body part inserted into the outer member, an inner incision part formed by cutting a part of the inner body part to extend in a direction oblique to the longitudinal direction of the inner body part, and an inner An inner blade portion sharply formed at an acute angle on one side edge of the incision portion. The rotation driving device rotates the inner member relative to the outer member so that the inner blade portion moves in a direction crossing the outer blade portion with the human tissue entering through the outer incision portion located in the middle.

Description

technical field [0001] The present invention relates to a biopsy device for incising and examining internal tissues of a human body, and more specifically, to a biopsy device having a structure capable of improving the performance of dissecting tissue and reducing discomfort of a patient during surgery . Background technique [0002] In general, a biopsy device is used to insert a needle-shaped device into a portion of tissue to be examined and to incise the tissue. This biopsy device is used on soft tissue other than bone, to cut through the tissue. Recently, the histological examination of breast tissue by dissecting tissue using a biopsy device has been increasing. Although breast tissue has soft tissue, it has the characteristics of very tough or hard tissue due to the high amount of fibrous tissue. Therefore, it is important for a biopsy device for breast tissue to have excellent incision performance capable of effectively incising tough tissue. [0003] figure 1 w...
