Description
Technical field
The invention belongs to medical operating assistant product technical field, be specifically related to a kind of marrow puncture needle.
Background technology
Bone marrow puncture is a kind of diagnostic techniques gathering bone marrow fluid, and it is usually used in three below aspect: 1, various in addition to hemophilia
Hemopathic diagnosis, Differential Diagnosis and follow up.2, the erythrocyte of unknown cause, leukocyte, platelet counts increase, subtract
Less and paramorph diagnosis.3, the diagnosis of the heating of unknown cause and Differential Diagnosis.The most of many uses, no matter hospital
Scale, have every day a lot of patient need to go this check.Therefore, bone marrow puncture is that clinical medical personnel must grasp
A kind of technology, and the core of bone marrow puncture is the satisfaction drawn materials, but owe practician, especially abecedarian for operation, take
Material satisfaction is the most optimistic.Marrow puncture needle conventional in bone marrow puncture at present is made up of following three parts: 1, needle handle,
Lower section is connected to be about the fine needle of 10cm, fluted on pin, middle for inhaling pulp cavity.2, the stop being installed on needle handle, long
About 3cm and the screw of fixing stop thereof, be connected with needle handle by groove.3, it is installed on the nook closing member inhaled in pulp cavity, is about 11cm.
During bone marrow aspiration, the quality and quantity taking bone marrow fluid is a very difficult assurance, is also a critically important link, especially
Practician is owed for abecedarian and operation.And failure of drawing materials is modal two reasons: 1, because the most not, sclerotin the hardest
Or the reasons such as anxiety make marrow puncture needle not actually enter medullary cavity, thus cause the defective of bone marrow fluid matter and cause bone marrow
Puncture failure.2, due to reasons such as operating process are unskilled, nervous, extract content after entering medullary cavity and too much or puncture through
Extracting the most in time after extracting nook closing member in journey and covering causes bone marrow fluid to overflow so that bone marrow fluid dilutes, and causes result inaccurate even
Mistake, thus have to repeat extraction, not only take time and effort, and bring misery to patient.Mould card tradition bone marrow thus
Puncture needle has a disadvantage in that 1, personal error is relatively big, affects result；2, in piercing process, take time and effort, the matter drawn materials
Wayward with amount, cause resultant error even mistake.
Summary of the invention
Present invention is generally directed to traditional puncture needle and there is the problem that personal error is big, take time and effort, it is provided that a kind of marrow puncture needle.
The present invention solves the problems referred to above and the technical scheme taked is:
A kind of marrow puncture needle, including trocar sheath and nook closing member, described trocar sheath is body and is punctured above cylinder with being positioned at by puncturing cylinder
Trocar sheath connecting portion composition, the bottom puncturing cylinder is oblique needle point, and described nook closing member includes loosing core and nook closing member connecting portion, and nook closing member connects
The top of the bottom in portion and trocar sheath connecting portion with the use of, wherein: also include knob and sealing-plug, described knob is with nook closing member even
The top meeting portion is threaded connection, in sealing-plug is arranged on and looses core, the top of sealing-plug be connected with knob by connecting rod and
Drive sealing-plug in interior movement of loosing core by rotary knob, be provided with screw thread puncturing distance oblique needle point 0.5 centimeters on cylinder.
Further, the present invention is provided with limited block on the inner surface of described knob, is provided with three limits at the top of nook closing member connecting portion
Position groove, limited block mates use with stopper slot, is 0 when limited block mates with the stopper slot of lower section, when limited block and centre
During stopper slot coupling, knob drives sealing-plug to move up to drive 0.1 milliliter of bone marrow fluid of extraction of loosing core, when limited block and top
During stopper slot coupling, knob drives sealing-plug to move up to drive 0.2 milliliter of bone marrow fluid of extraction of loosing core.
A length of 1 centimetre of screw thread of the present invention.
Limited block of the present invention is cylindrical, and described stopper slot is circular.
The present invention uses technique scheme, is provided with the screw thread of long 1 centimetre puncturing distance oblique needle point 0.5 centimeters on cylinder, makes
Puncture the frictional force increase of cylinder and sclerotin, even if sclerotin is hard again, also can enter medullary cavity more effortlessly.Simultaneously in interior setting of loosing core
Sealing-plug constitutes airtight negative pressure device, and capacity is 0.2ml, is 0 when limited block mates with the stopper slot of lower section, when limited block and
During middle stopper slot coupling, knob drives sealing-plug to move up to drive 0.1 milliliter of bone marrow fluid of extraction of loosing core, when limited block with
When the stopper slot of top mates, knob drives sealing-plug to move up to drive 0.2 milliliter of bone marrow fluid of extraction of loosing core.Complete Deng extraction
After, will loose core and extract, bone marrow fluid will be coated onto on microscope slide, direct smear.Compared with prior art, the present invention has following has
Benefit effect: 1, save syringe, make puncture type of goods reduce, is more easy to operation；2, the quality and quantity of bone marrow extraction liquid more holds
Easy to control, provide great convenience for abecedarian；3, Novel marrow puncture needle uses simple, easily grasps.
