Nook closing member and needle guard are together pricked into position to be sampled by needle point one, nook closing member is released afterwards in needle guard, portion of tissue is placed in sampling groove, afterwards can by needle guard be promoted towards nook closing member, utilize needle point two and nook closing member outer wall to coordinate the tissue be breaking in sampling groove, because sampling groove is located on the nook closing member axis side of needle point two correspondence, therefore needle point two directly can cut off tissue, make sampling convenient, also can alleviate patient suffering simultaneously.
In above-mentioned a kind of Novel biopsy needle, described nook closing member outer wall and endoporus hole wall are respectively equipped with the point-like positioning convex and bar shaped detent that cooperatively interact, and detent is arranged along nook closing member axis, described positioning convex is placed in detent and also can moves along detent length direction, and when positioning convex is positioned at detent one end, described sampling groove is placed in endoporus, and when positioning convex is placed in the detent other end, described sampling groove entirety stretches out endoporus.
Coordinated by positioning convex and detent and play positioning action, avoid needle point one and needle point two dislocation.
In above-mentioned a kind of Novel biopsy needle, described sampling groove bottom land and nook closing member axis being parallel, and sampling groove both sides cell wall is provided with pointed barbs.
Conveniently fixing organization is caught on by barb.
In above-mentioned a kind of Novel biopsy needle, described nook closing member outer wall and the seamless applying setting of endoporus hole wall.
In above-mentioned a kind of Novel biopsy needle, described sampling groove bottom land is matsurface.
Compared with prior art, this utility model tool has the following advantages:
Nook closing member and needle guard are together pricked into position to be sampled by needle point one, nook closing member is released afterwards in needle guard, portion of tissue is placed in sampling groove, afterwards can by needle guard be promoted towards nook closing member, utilize needle point two and nook closing member outer wall to coordinate the tissue be breaking in sampling groove, because sampling groove is located on the nook closing member axis side of needle point two correspondence, therefore needle point two directly can cut off tissue, make sampling convenient, also can alleviate patient suffering simultaneously.
