Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of hematology marrow puncture needle.
Background technology
Bone marrow puncture is that the one gathering bone marrow fluid commonly uses diagnostic techniques, and bone marrow aspiration is also usually used in blood cell morphology inspection clinically, also can be used for hematopoietic stem cell collection, cultivation, CYTOGENETIC ANALYSIS OF ONE and Pathogen Biology inspection etc.
For gathering the sampling instrument of bone marrow fluid usually based on medullo-puncture needle, conventional medullo-puncture needle orientation when puncturing is inaccurate, and the syringe needle of medullo-puncture needle may slide into ilium side, can not enter medullary cavity, or passes medullary cavity again after penetrating medullary cavity; And require that marrow puncture needle provides larger puncture force, require great effort time-consuming.Along with the raising of people's lives condition, the increase of bone mineral density, especially between twenty and fifty patient, medical worker, when applying conventional marrow puncture needle and puncturing, needs great strength just can penetrate periosteum, is unfavorable for clinical manipulation.
Utility model content
The purpose of this utility model is the hematology's marrow puncture needle providing a kind of structure simple, easy to use, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of hematology marrow puncture needle, comprise puncture needle tubing and sleeve pipe, described puncture needle tubing is located at the inside of sleeve pipe, puncture needle tubing is connected with casing threads, the outside of sleeve pipe is provided with base plate, the outside of puncture needle tubing is also connected with limiting plate, the inside of puncture needle tubing offers cavity, the left end of puncture needle tubing is provided with piercing needle, puncture needle tubing is provided with some pin holes near the position of piercing needle, the right-hand member of puncture needle tubing is provided with needle tubing base, the right side of described needle tubing base is provided with cross recess, the right part of puncture needle tubing is also provided with the reservoir communicated with cavity, described reservoir is provided with graduation mark, reservoir is also provided with negative pressure sac.
As further program of the utility model: described pin hole is oval or circular.
As this utility model further scheme: described puncture needle tubing is peripherally provided with 3 pricking with needle holes, and often row is provided with 4 pin holes.
Compared with prior art, the beneficial effects of the utility model are: be provided with needle tubing base, the right side of described needle tubing base is provided with cross recess, the electric screw driver that can carry out mating the same specification connected is connected, by electric power, the rotation of puncture needle tubing is penetrated periosteum and enters bone marrow, change original artificial rotation piercing method, by electric power, puncture needle is worn out periosteum fast and enter bone marrow, reduce the artificial difference of operation, reduce patient suffering, be particularly useful for the between twenty and fifty patient that bone density is high, by employing base plate and the limiting plate facilitating adjusting position, medullo-puncture needle orientation when puncturing can be prevented inaccurate, the syringe needle of medullo-puncture needle may slide into ilium side, medullary cavity can not be entered, the problems such as medullary cavity are passed again after penetrating medullary cavity, achieve Needle localization accurately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of needle tubing base.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
