Abstract
The utility model discloses a bone marrow puncture biopsy needle which comprises a needle tube, a base connected to one end of the needle tube, and a spiral cutting edge arranged at the other end of the needle tube; the bone marrow puncture biopsy needle is characterized in that a first needle core and a second needle core which are matched with the inner wall of the needle tube respectively are further included, wherein the second needle core is shorter than the first needle core; and a polished rod is arranged at the part, which is adjacent to the spiral cutting edge, of the needle tube, threads are arranged at the part, which is adjacent to the base, of the needle tube, and a locking nut is matched with a limit threaded sleeve matched with the threads on the needle tube. In the bone marrow puncture biopsy needle, the operation method is simple, the depth of insertion of the needle is easily controlled, the success ratio of puncture is high, the time for sampling of puncture diagnosis and for treatment is shortened, the problem of frequent and repeated puncture is avoided, the pain of patients is relieved, meanwhile, the synchronous sampling at the same part of the bone marrow smear and the bone marrow biopsy tissue is ensured, and the bone marrow puncture biopsy needle is used for puncture and biopsy of other aspects besides bone marrow and biopsy.
Description
Technical field
This utility model belongs to medical apparatus and instruments, is specifically related to a kind of bone marrow needle biopsy pin.
Background technology
The marrow puncture needle that uses can only be used as marrow aspiration liquid at present, does examination of bone marrow smear, and can not be used as the bone marrow biopsy tissue examination.When needs are done bone marrow biopsy, just need to use myeloid biopsy needle, like this, need do secondary puncture when doing bone marrow smear and bone marrow biopsy, bring misery to the patient.And the myeloid biopsy needle that uses at present is made up of sleeve pipe, pin stamen and joint pin three parts.Three parts of this biopsy needle are separated from each other, and in operating process, joint pin wherein need connect and take off, use inconvenient, the fixing not firm slippage that easily causes of joint pin causes the failure of drawing materials, and lacks adjusting knob and labelling on the sleeve pipe, be difficult for grasping depth of needle, punctured and simple and easyly stopped up, punctured and deeply easily pass the bone marrow injury internal organs, and cause puncture failure by cortical bone, thereby puncture brings misery to the patient so that need once more, and can not guarantee it is to draw materials at same position.
Summary of the invention
The purpose of this utility model provides a kind of bone marrow needle biopsy pin, a kind of simple to operation, easily grasp depth of needle, be difficult for causing slippage, prevent puncture failure, improve the bone marrow biopsy success rate, can finish bone marrow smear, can carry out the myeloid tissue biopsy simultaneously again.
A kind of bone marrow needle biopsy pin described in the utility model, comprise needle tubing (3), be connected the base (3-1) of needle tubing one end, the other end of needle tubing is the spiral blade, it is characterized in that: also comprise first nook closing member and second nook closing member that can cooperate with needle interior wall respectively, and second nook closing member is shorter than first nook closing member;
Needle tubing near one section of the spiral blade for polished rod, be provided with screw thread near a section of base, a locking nut and a spacing swivel nut cooperate with needle tubing on threaded engagement.
Further, the shank of described first nook closing member is provided with first rectangular boss, this first rectangular boss and the rectangular recess corresponding matching that is located on the base; The end of described first nook closing member is tapered syringe needle, and first nook closing member passes its tapered syringe needle of needle tubing and stretches out from the spiral blade end of needle tubing.
Further, the shank of described second nook closing member is provided with second rectangular boss, this second rectangular boss and the rectangular recess corresponding matching that is located on the base; The end of described second nook closing member is a forward type, and second nook closing member passes that its end of needle tubing is positioned at needle tubing and apart from spiral blade end 1.5-2cm.
Further, described spacing swivel nut is provided with a disk near an end of spiral blade.
This utility model operational approach is simple, grasp depth of needle easily, the success rate height of puncture, shortened the time that the puncture diagnosis is drawn materials and treated, avoided repeatedly, repeated localised puncture, alleviated patient's misery, guaranteed that simultaneously bone marrow smear and bone marrow biopsy tissue draw materials synchronously with the position, this utility model can also be used for the puncture and the biopsy of others except being used for bone marrow aspiration and biopsy.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is elaborated:
, comprise needle tubing 3, be connected the base 3-1 of needle tubing one end, the other end of needle tubing is spiral blade 3-2 to a kind of bone marrow needle biopsy pin shown in Figure 5 referring to Fig. 1; Also comprise first nook closing member 1 and second nook closing member 2 that can cooperate with needle tubing 3 inwalls respectively, and second nook closing member, 2 to the first nook closing members 1 are short; Needle tubing 3 near one section of spiral blade 3-2 for polished rod, be provided with screw thread 3-3 near a section of base 3-1, a locking nut 4 and a spacing swivel nut 5 cooperate with screw thread 3-3 on the needle tubing 3 and cooperate.
The shank of described first nook closing member 1 is provided with the first rectangular boss 1-1, this first rectangular boss and the rectangular recess corresponding matching that is located on the base 3-1; The end of described first nook closing member 1 is tapered syringe needle, and first nook closing member 1 passes needle tubing 3 its tapered syringe needles and stretches out from the spiral blade 3-2 of needle tubing end.
The shank of described second nook closing member 2 is provided with the second rectangular boss 2-1, this second rectangular boss and the rectangular recess corresponding matching that is located on the base 3-1; The end of described second nook closing member 2 is a forward type, and second nook closing member 2 passes needle tubing 3 its ends and is positioned at needle tubing and holds 1.5-2cm apart from spiral blade 3-2.
Described spacing swivel nut 5 is provided with a disk 5-1 near the end of spiral blade 3-2.
Carry out bone marrow aspiration referring to Fig. 5 with the bone marrow needle biopsy pin, regulate the position of spacing swivel nut earlier, determine the degree of depth of puncture, be locked with locking nut then.Need to determine to puncture behind the puncture position, first nook closing member is passed sclerotin slowly after, the sensation resistance takes out first nook closing member when weakening then, by the through hole of needle tubing syringe pump bone marrow, just can make bone marrow smear.When carrying out bone marrow biopsy with the bone marrow needle biopsy pin, second nook closing member is being inserted needle tubing, locking nut is regulated 1.5-2 cm to handle orientations, spacing swivel nut is fitted to handle orientations rotation and locking nut simultaneously, the clockwise direction turning handle, make the disk and the skin attachement of the end face of spacing swivel nut, and utilize the spiral blade of needle tubing to cut the bone marrow group and go in needle tubing.Continue rotation in a clockwise direction and withdraw from the bone marrow needle biopsy pin, take out second nook closing member, first nook closing member is turned back to needle tubing, myeloid tissue is released outside the pin, be used for biopsy.
