Abstract
The utility model discloses a multi-hole ring rotating type myeloid biopsy needle in the field of medical apparatus, which comprises a needle core and a needle tube that are matched. The need tube isfixed with a need tube seat provided with threads at the root part on the axial direction; the need tube seat is arranged on the centre of a wing-shape handle in a penetrating way; the need core is arranged on a needle core seat; the needle core seat is fixed at the centre of a rotary seat; when the need core is completely inserted into the need tube, the end part of the need core protrudes out ofthe need tube; the needle tube near the end part thereof is provided with a lateral hole. After the puncturing of the multi-hole ring rotating type myeloid biopsy needle, the needle core is taken out; then the tissue sample of the disease location is sucked by a syringe; as the existing of the lateral hole, the tissue sample surrounding the side direction hole can be sucked together; thus being capable of obtaining the tissue sample within a larger range for examining; even if the punctuation is not very accurate, a comparatively accurate examining result can also be obtained. The multi-holering rotating type myeloid biopsy needle is specially used for the sampling examining of disease location, in particular to marrow examining.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of utensil of the bone marrow that is used to puncture.
Background technology
In the prior art, the rotatable marrow puncture needle of a kind of ring is arranged, comprise the nook closing member and the needle tubing that match, the needle tubing seat that needle tubing and root are provided with screw thread axially fixes, the needle tubing seat runs through the handle center that is arranged on wing, described nook closing member is arranged on the needle core base, needle core base is fixed on the center of a rotating seat, the rotating seat periphery is arranged with two projections, handle is provided with the opening that can hold rotating seat, the edge of opening both sides is respectively equipped with the circumferential recess that matches with projection, and nook closing member axially passes the end that the needle tubing seat extend into needle tubing.During work, by rotation and push rotating seat, can realize the fixing of nook closing member and needle tubing and separate that when projection snapped in the circumferential recess, the axial relative fixed of nook closing member and needle tubing can not be moved, and can carry out bone marrow aspiration easily; By the backward rotation rotating seat, make projection withdraw from circumferential recess, needle tubing assembly and nook closing member assembly are separated, in piercing process, can take out nook closing member, be connected with aspirator such as syringe etc. by the screw thread on the needle tubing seat, can extract bone marrow, also can be in bone marrow liquid medicine injection.Its weak point is: in the process that this marrow puncture needle is taken a sample, can only be drawn into the tissue samples of needle tubing head position after puncture, because of its sampling scope is little, and usually can not obtain the accurate diagnostic result of patient part.
The utility model content
The purpose of this utility model provides the rotatable myeloid biopsy needle of porous ring, makes it can obtain more tissue samples, to check accurately.
The purpose of this utility model is achieved in that the rotatable myeloid biopsy needle of porous ring, comprise the nook closing member and the needle tubing that match, the needle tubing seat that needle tubing and root are provided with screw thread axially fixes, the needle tubing seat runs through the handle center that is arranged on wing, described nook closing member is arranged on the needle core base, and needle core base is fixed on the center of a rotating seat, when nook closing member inserts needle tubing fully, the end nipple of nook closing member is provided with at least one sidewise hole near its end for outside the needle tubing on the needle tubing.
Nook closing member is taken out in this utility model puncture back, again with the tissue samples of syringe pump patient part, because the existence of sidewise hole is arranged, tissue samples around the sidewise hole also can be extracted out together, like this, in larger scope tissue samples can be obtained for check,, also assay more accurately can be obtained even puncture is very inaccurate.This device is exclusively used in the pick test of various patient parts, is particularly useful for the bone marrow check.
As further improvement of the utility model, described nook closing member end is provided with arcual cutting blade.Because otch has tension force, the arc cutting blade can guarantee that the otch inboard is separated with cutting blade, makes more tissue samples can arrive syringe tip, so that check.
Description of drawings
Fig. 1 is this utility model structural representation.
Fig. 2 is that the A of middle nook closing member of Fig. 1 is to view.
Fig. 3 moves back to the interior structural representation of needle tubing for nook closing member among Fig. 1.
Wherein, 1 handle, 2 rotating seats, 3 needle core bases, 4 needle tubing seats, 5 nook closing members, 6 needle tubings, 7 sidewise holes, 8 cutting blades.
The specific embodiment
As figure, be the rotatable myeloid biopsy needle of porous ring, comprise the nook closing member 5 and the needle tubing 6 that match, needle tubing 6 axially fixes with the needle tubing seat 4 that root is provided with screw thread, and needle tubing seat 4 runs through handle 1 center that is arranged on wing, described nook closing member 5 is arranged on the needle core base 3, needle core base 3 is fixed on the center of a rotating seat 2, and when nook closing member 5 inserted needle tubing 6 fully, the end nipple of nook closing member 5 was for outside the needle tubing 6, enclose sidewise hole 7 near its end along being circumferentially with one on the needle tubing 6, this sidewise hole can be one at least.Nook closing member 5 ends are provided with arcual cutting blade 8.
During work, by rotation and push rotating seat 2, can realize the fixing of nook closing member 5 and needle tubing 6 and separate, can puncture easily; After the puncture, take out nook closing member 5, extract tissue samples with syringe and test, because the existence of sidewise hole 7 is arranged, the tissue samples that can be drawn into is in larger scope tested.
Claims (2)
1, the rotatable myeloid biopsy needle of porous ring, comprise the nook closing member and the needle tubing that match, the needle tubing seat that needle tubing and root are provided with screw thread axially fixes, the needle tubing seat runs through the handle center that is arranged on wing, described nook closing member is arranged on the needle core base, and needle core base is fixed on the center of a rotating seat, when nook closing member inserts needle tubing fully, the end nipple of nook closing member is characterized in that for outside the needle tubing: be provided with at least one sidewise hole near its end on the needle tubing.
