no. 1 Embodiment approach

[0031] figure 1 and figure 2 The jig 100 for tissue division according to the first embodiment of the present invention is shown. figure 1 is an exploded perspective view, figure 2 It is a perspective view showing the state of the jig 100 for tissue division when the needle biopsy tissue is divided. in addition, image 3 It is a partially enlarged cross-sectional view of the jig 100 for tissue division when the needle biopsy tissue S is divided. The jig 100 for tissue division has a base 101 for tissue division and a cutting blade set 103 . The base unit 101 for tissue division has a tissue mounting portion 102 on which a needle biopsy tissue is placed. The cutting blade set 103 includes a cutting blade member 105 and a guide 107 .

[0032] The tissue dividing base 101 and the cutting blade set 103 have a positioning mechanism for mutually fixing positions. The positioning mechanism in this embodiment is constituted by combining and fixing the cross-sectional shape of...

[0047] Image 6 A jig 200 for tissue division according to a second embodiment of the present invention is shown. Image 6 It is an exploded perspective view of the jig 200 for tissue division in a state where the needle biopsy tissue S is taken out from the biopsy needle 120 . The jig 200 for tissue division has a base 201 for tissue division and a cutting blade set 203 . The base unit 201 for tissue division has a tissue mounting portion 202 on which the needle biopsy tissue S is placed. In addition, in Image 6 In FIG. 2 , the state where the sheet member 209 having affinity with the needle biopsy tissue S is placed on the tissue placement portion 202 is shown. The cutting blade set 203 includes a cutting blade member 205 and a guide portion 207 . In the present embodiment, the guide portion 207 is integrally formed with the cutting blade member 205 .

[0056] Figure 9 A jig 300 for tissue division according to a third embodiment of the present invention is shown in . The jig 300 for tissue division has a base 301 for tissue division and a cutting blade set 303 . The base unit 301 for tissue division has a tissue mounting portion 302 on which the needle biopsy tissue S is placed. In addition, in Figure 9 In FIG. 2 , the state in which the sheet-like member 309 having affinity with the needle biopsy tissue S is placed on the tissue placement portion 302 is shown. The cutting blade set 303 includes a cutting blade member 305 and a hinge 307 .

[0057]The hinge 307 in this embodiment is the positioning mechanism and guide part in the present invention. In the present embodiment, the hinge 307 connects the cutting blade member 305 and the base for tissue division 301 to fix their positions with each other. Furthermore, the cutting blade member 305 is guided by the hinge 307 so that the cutting blade member 305 moves to the...

Abstract

Provided is a jig for tissue division capable of easily dividing a needle biopsy tissue for biopsy over its entire length. It has a base for tissue division and a cutting knife set. The base 301 for tissue division has a tissue placement part 302 on which a needle biopsy tissue S is placed, and the cutting knife set 303 has a cutting knife member 305 and a guide part 307 (hinge). The base 301 and the cutting blade set 303 have a positioning mechanism 307 (hinge) for mutually fixing positions, the cutting blade member 305 is provided with a cutting blade 306 in the longitudinal direction of the tissue placement portion 302, and the guide portion 307 guides the cutting blade member 305 In order to move the cutting blade member 305 to the fixed position of the base part 301 for tissue division, the cutting blade set 303 is arranged at a predetermined position on the base part 301 for tissue division by the positioning mechanism, and the cutting blade member 305 is moved using the guide part 307 , the cutting blade 306 is arranged at a position for dividing the needle biopsy tissue S placed on the tissue mounting part 302 in the longitudinal direction.

Description

technical field [0001] The present invention relates to a jig (English: jig) for tissue division. Background technique [0002] A biopsy is an indispensable means for accurate diagnosis of a disease. Biopsies are most commonly performed using a biopsy gun. In a biopsy gun, typically more than one needle is advanced into the target tissue under ultrasound or MRI guidance. Next, the tissue piece (core (English: core)) is taken out together with the biopsy needle. The tissue pieces are either immersed in a fixative (formalin fixation) or frozen after removal from the needle. Next, the tissue piece is embedded in paraffin, cut, frozen and differentiated, and mounted on a microscope slide for staining, nucleic acid analysis, or other analysis. The processing steps for visual analysis of tissue slices (fixative, paraffin embedding, and staining, etc.) and molecular biological analysis (in situ PCR, fluorescence in situ hybridization, etc.) of tissue slices do not coexist in mo...
