Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of vacuum Wicresoft myeloid biopsy needle.
Background technology
In clinical diagnosis technology operation, bone marrow aspiration inspection can be successful in most of patient, but if encounter " dry tap " phenomenon, when namely can not taking out bone marrow fluid, just cannot diagnose.This situation sees myelosclerosis, myelofibrosis (constitutional or Secondary cases), especially malignant tumor is (as breast carcinoma, pulmonary carcinoma, carcinoma of prostate and gastric cancer etc.) bone marrow neoplasms caused by myelofibrosis and some leukemia (such as hairy cell leukemia), Lymphoma bone marrow puncture Chang Buneng success.Adopt bone marrow biopsy art just can make up the deficiency of bone marrow puncture, bone marrow biopsy art abbreviation bone marrow biopsy, make pathological examination by the cylindrical bone myeloid tissue that about 0.5 ~ 1 centimeter length of a fritter got by a special puncture needle exactly.The material taken out maintains complete myeloid tissue structure, can make up the deficiency of bone marrow aspiration.Not only can understand composition and the germinal cell distribution situation of medullary cell, and energy observation of cell form, be convenient to make pathological diagnosis, significant to the diagnosis of aplastic anemia, myelodysplastisches disease.And biopsy extraction is large, not only can understand the cell component in bone marrow, and can keep bone marrow structure, malignant cell is more easily familiar with, and is convenient to pathological diagnosis.Also the diagnosis of some disease needs to understand myeloid tissue structure, such as aplastic anemia, myelodysplastic syndrome, and malignant tumor bone marrow transfer etc. just needs myelopathy Neo-Confucianism to check.Bone marrow biopsy art organizes how many understandings to have the certain significance to aplastic anemia bone marrow hematogenesis; In addition, the judgement of biopsy to BMN or fatty marrow is also meaningful.
But when carrying out bone marrow biopsy, usually because gathering undersampling, needing repeated sampling, causing unnecessary misery to patient, increase and infect probability, increase passage disease inspection tumor cell and remain.
Summary of the invention
The purpose of this utility model is to provide a kind of vacuum Wicresoft myeloid biopsy needle, to make up the deficiencies in the prior art.
A kind of vacuum Wicresoft myeloid biopsy needle, it is characterized in that comprising a root puncture pipe, this puncture tube is the reducer pipe that first half diameter is less than latter half of diameter, and the latter half of side of puncture tube is provided with negative-pressure suction pipe, the intersection of described negative-pressure suction pipe and puncture tube is provided with filter screen, and negative-pressure suction pipe end is provided with vacuum aspiration port; Also be provided with a sampling probe in described puncture tube, on described sampling probe, cover has baffle plate.
Above-mentioned baffle plate is sealedly connected on the end of puncture tube by buckle, and the diameter of baffle plate is 8mm.
The diameter of above-mentioned puncture tube leading section is 3mm, and latter half of diameter is 8mm.
Above-mentioned puncture tube front end is cambered surface acicular texture and is provided with perforate.
Above-mentioned sampling probe diameter is 2mm, and front end is provided with sampling syringe needle, tail end is provided with handle.
Above-mentioned vacuum aspiration port diameter is 8mm.
The utility model has the advantage of: structure is simple, and easy to use, cost is lower, economy and durability, effectively can shorten patient's biopsy time and reduce patient painful.Reduce and infect probability, reduce passage disease inspection tumor cell and remain, increase the security of surgical patient.The routine bone marrow biopsy needle of comparatively passing by is taked specimen method to compare and is eliminated many troubles, adds convenience, controllability.

Detailed description of the invention
A kind of vacuum Wicresoft myeloid biopsy needle, it is characterized in that comprising a root puncture pipe 1, this puncture tube 1 is less than the reducer pipe of latter half of diameter for first half diameter, consider the effect of puncture sampling, and the latter half of side of puncture tube 1 is provided with negative-pressure suction pipe 6, and avoid sampling to organize not lost by vacuum suction, described negative-pressure suction pipe 6 is provided with filter screen 9 with the intersection of puncture tube 1, and conveniently with vacuum suction equipment connection, negative-pressure suction pipe 6 end is provided with vacuum aspiration port 4; Also be provided with a sampling probe 3 in described puncture tube 1, in order to ensure that the specimen of puncture sampling is not easily polluted, on described sampling probe 3, cover has baffle plate 2.
For preventing sampling tissue because the effect of negative pressure recalls, above-mentioned baffle plate 2 is sealedly connected on the end of puncture tube 1 by buckle, and the diameter of baffle plate 2 is 8mm.
Consider and reduce the wound face of puncture to sufferer, the diameter of above-mentioned puncture tube 1 leading section is 3mm, and latter half of diameter is 8mm.
Consider the effect of puncture, above-mentioned puncture tube 1 front end is cambered surface acicular texture and is provided with perforate 5.
Consider accuracy and the operability of puncture, above-mentioned sampling probe 3 diameter is 2mm, and front end is provided with sampling syringe needle 7, tail end is provided with handle 8.
Consider the effect of vacuum suction, above-mentioned vacuum aspiration port 4 diameter is 8mm.
Consider that handled easily is installed, above-mentioned vacuum aspiration port 4 diameter is 8mm, and is provided with buckle.
When using this utility model, myeloid biopsy needle biopsy operational approach: have heparin saline (1mg=500ml) container in advance, organizes censorship with selection suspicious lesions for subsequent use.Determine biopsy site, cutting puncture orifice, puncture tube 1 is inserted, thrust with by sampling probe 3, multi-direction after entering bone marrow, multi-level have amplitude rotating needle fast, make the other tissue of syringe needle and cell detachment, by another termination vacuum aspiration port 4 of pvc pipe of band internal thread, while rotate negative pressure simultaneously, remove negative pressure after going out tissue, avoid blood pumpback, prevent specimen from inhaling in negtive-pressure implement, withdraw from sampling probe 3 to negative-pressure suction pipe 6 place subsequently, open baffle plate 2, suspicious lesions tissue has been inserted in heparin saline container.Prevent hematoma from being formed, as hemorrhage in soft tissue then with gelfoam filling if desired, osseous tissue then uses bone cement hemostasis with packs.This utility model structure is simple, processing ease.Effectively can shorten patient's biopsy time and reduce patient painful.Reduce and infect probability, reduce passage disease inspection tumor cell and remain, increase the security of surgical patient.The routine bone marrow biopsy needle of comparatively passing by is taked specimen method to compare and is eliminated many troubles, adds convenience, controllability.
