Abstract
The utility model relates to a simple swift myeloid biopsy needle is used for clinically, and its technical scheme is: form including upper cover, dabber, spring, interior trocar, handle, outer trocar. Interior trocar upper end is equipped with upper cover, dabber, spring, screens ware, and the lower extreme is equipped with interior needle. Handle one side is equipped with the cavity, the middle part is equipped with clamping hole, trigger point, and the lower extreme is equipped with outer trocar. Do you during the use, confirm 5 does the broken bone cortex of interior spicula get into the ossis, 6 does outer trocar card press 8 in bone cortex the trigger point, this moment 7 does the screens ware return and contracts 2 does spring release elasticity drive 5 interior needle and 1 the cap is upwards bounce, 5 does interior needle break away from bone cortex, 7 is screens ware card 9 upper hole. Control 65 jiaos of swings 4 the handle, does the inserting needle make 6 once more does outer trocar get into ossis 10 does 20mm get required sample, then 65 jiaos of swings 4 once more is the handle with 6 outer trocar is extracted. Press 1 does the cap utilize 5 marrow live body tissue is released to interior needle, inspects by ready samples in putting into the test tube that contains 95% ethanol or 10% formaldehyde.
Description
Technical field
The utility model is related to a kind of simple and fast myeloid biopsy needle.
Background technology
At present, on the market biopsy needle used is cumbersome, and sampling amount is few, and clinical biopsy efficiency is low.My company for this
To cater to, the market demand is special to research and develop this product.
The content of the invention
It is to improve prior art in problem present on Clinical practice that the purpose of this utility model is, there is provided one kind is grasped
Make the simple Medical myeloid puncture needle that can improve bone marrow biopsy puncture success rate again.Greatly reduce the workload of medical personnel.
Technical scheme is：A kind of new simple and fast myeloid biopsy needle, be by upper lid, mandrel, spring, interior trocar,
Handle, outer casing needle composition.The interior trocar upper end is provided with lid, mandrel, spring, screens device, and lower end is provided with interior pin.The handle
Side is provided with cavity, middle part and is provided with screens hole, trigger point, and lower end is provided with outer pin and is provided with scale.The interior pin, outer casing needle are all
Three face cone shapes.
The utility model compared with the prior art, with advantages below：1. body mechanics's handle design can make clinical manipulation
Personnel are more comfortable in the middle of using process；2. interior pin is exited without the need for whole process in operating process；3. need not install that conversion catches additional can
Complete sampling；4. needle point is all three face cone shapes inside and outside.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：Pin, 6- outer casing needles, 7- screens devices, 8- trigger points, 9- in 1- caps, 2- springs, 3- mandrels, 4- handles, 5-
Upper hole, 10- bottoms hole.
Specific embodiment
Below in conjunction with the accompanying drawings 1 pair of the utility model puncture needle is further elaborated：
This product original state is that 1- caps are in closure state with 4- handle upper ends, and 2- springs are in elastic compression shape
State, 7- screens devices are stuck in 10- bottoms hole, while spicula is for about 2.5 millimeters of 6- outer casing needles in 5-.When using, pin in 5- is confirmed
Break through cortex of bone and enter ossis, 6- outer casing needles are stuck in cortex of bone, press 8- trigger points, now 7- screens device retraction, 2- bullets
Spring release elastic force drives pin and 1- caps in 5- to pop up, and pin departs from cortex of bone in 5-, and 7- screens devices are stuck in the upper holes of 9-.It is left
Right 65 ° of angular oscillatory motion 4- handles, again inserting needle make 6- outer casing needles take required sample into ossis 10-20mm, then left and right again
65 ° of angular oscillatory motion 4- handles extract 6- outer casing needles.Pressing 1- caps, using pin in 5- marrow biological tissue is released, and is inserted and is filled
Censorship in the test tube of 95% ethanol or 10% formaldehyde.
