Description
Technical field
This utility model belongs to medical operating assistant product technical field, is 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, except hemophilia
Outer various hemopathic diagnosis, Differential Diagnosis and follow up.2, the erythrocyte of unknown cause, leukocyte, platelet counts increase
Many, reduce and paramorph diagnosis.3, the diagnosis of the heating of unknown cause and Differential Diagnosis.The most of many uses, no
Opinion hospital size size, have every day a lot of patient need to go this check.Therefore, bone marrow puncture is that clinical medical personnel is necessary
A kind of technology grasped, and the core of bone marrow puncture is the satisfaction drawn materials, but owe practician for operation, especially begin to learn
Person, satisfaction of drawing materials 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,
It is about 3cm and the screw of fixing stop thereof, is 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,
Practician is owed particularly with abecedarian and operation.And failure of drawing materials is modal two reasons: 1, because the most not, sclerotin
The reason such as the hardest or nervous makes marrow puncture needle not actually enter medullary cavity, thus causes the defective of bone marrow fluid matter and lead
The failure of cause bone marrow aspiration.2, due to reasons such as operating process are unskilled, nervous, enter extract after medullary cavity content too much or
Extracting the most in time after extracting nook closing member in piercing process and covering causes bone marrow fluid to overflow so that bone marrow fluid dilutes, and causes result not
The most even mistake, thus have to repeat extraction, not only take time and effort, and bring misery to patient.Mould card thus
Tradition marrow puncture needle has a disadvantage in that 1, personal error is relatively big, affects result；2, in piercing process, take time and effort, draw materials
Quality and quantity wayward, cause resultant error even mistake.
Utility model content
There is, mainly for traditional puncture needle, the problem that personal error is big, take time and effort in this utility model, it is provided that a kind of
Marrow puncture needle.
This utility model is that the technical scheme that solution the problems referred to above are taked is:
A kind of marrow puncture needle, including trocar sheath and nook closing member, described trocar sheath is body and by puncturing cylinder and being positioned at puncture
Trocar sheath connecting portion composition above Tong, the bottom puncturing cylinder is oblique needle point, and described nook closing member includes loosing core and nook closing member connecting portion, pin
The top of the bottom of core connecting portion and trocar sheath connecting portion with the use of, wherein: also include knob and sealing-plug, described knob with
The top of nook closing member connecting portion is threaded connection, and sealing-plug is arranged in loosing core, and connecting rod and knob are passed through in the top of sealing-plug
It is connected and drives sealing-plug in interior movement of loosing core by rotary knob, being provided with puncturing distance oblique needle point 0.5 centimeters on cylinder
Screw thread.
Further, this utility model is provided with limited block on the inner surface of described knob, at the top of nook closing member connecting portion
Being provided with three stopper slots, limited block mates use with stopper slot, is 0 when limited block mates with the stopper slot of lower section, when spacing
When block mates with middle stopper slot, knob drives sealing-plug to move up to drive 0.1 milliliter of bone marrow fluid of extraction of loosing core, and works as limit
When position block mates with the stopper slot of top, 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 described in the utility model.
Limited block described in the utility model is cylindrical, and described stopper slot is circular.
This utility model uses technique scheme, is provided with long 1 centimetre puncturing distance oblique needle point 0.5 centimeters on cylinder
Screw thread, makes puncture cylinder increase with the frictional force of sclerotin, even if sclerotin is hard again, also can enter medullary cavity more effortlessly.Taking out simultaneously
In-core arranges sealing-plug and constitutes airtight negative pressure device, and capacity is 0.2ml, is 0 when limited block mates with the stopper slot of lower section, when
When limited block mates with middle stopper slot, knob drives sealing-plug to move up to drive 0.1 milliliter of bone marrow fluid of extraction of loosing core,
When limited block mates with the stopper slot of top, knob drives sealing-plug to move up to drive 0.2 milliliter of bone marrow of extraction of loosing core
Liquid.After extraction, will loose core and extract, bone marrow fluid will be coated onto on microscope slide, direct smear.Compared with prior art, this reality
With novel having the advantages that 1, saving syringe, make puncture type of goods reduce, be more easy to operation；2, bone marrow extraction
The quality and quantity of liquid is easier to control, and provides great convenience for abecedarian；3, Novel marrow puncture needle uses simple, easily grasps.
