Description
Technical field
The utility model relates to hematology's appliance technology, especially a kind of New Blood section marrow puncture needle.
Background technique
Bone marrow puncture (bone marrow puncture) is a kind of common diagnostic techniques for taking bone marrow fluid, is checked
Content includes several aspects such as cytology, protozoon and bacteriology.Suitable for it is various it is hemopathic diagnosis, antidiastole and treatment with
It visits；Red blood cell, leucocyte, the platelet counts of unknown cause increase or reduce and morphological abnormalities；Unexplained fever is examined
Disconnected and antidiastole, can make marrow culture, bone marrow smear looks for helminth etc..
Current marrow puncture needle holds handle inserting needle when puncturing, and due to that need to penetrate sclerotin, therefore need to provide biggish puncture
Power can just penetrate periosteum, and operator is difficult to ensure vertical inserting needle when firmly, and larger due to puncturing dynamics, on puncture needle
Infinite place device easily punctures too deep, therefore dynamics bad assurance when puncturing, operate it is time-consuming and laborious, and in bone marrow extraction liquid,
The bad control of extraction dynamics such as overexerts and is easy to extract at syringe needle, and operation is inconvenient.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical disadvantages to provide a kind of New Blood section marrow puncture needle,
Can control paracentesis depth by the use of limit plate, handle and puncture tube are at T-shaped convenient for hand-held and control dynamics, push-pull ring in
Handle is used cooperatively, and suction action will not generate external broach degree to needle body is punctured, convenient for control extracting force.
The utility model solves the technical solution that technical problem uses are as follows: a kind of New Blood section marrow puncture needle, packet
It includes puncture tube, handle, puncture needle body, limit plate, telescopic rod, the puncture tube lower end is bolted and fixed with puncture needle body, puncture tube
Upper end is bolted and fixed with handle, and puncture tube lower half portion outer tube wall is equipped with graduation mark, and puncture tube top half two sides are symmetrically set
There is sliding groove, piston is equipped in puncture tube, is bolted and fixed with push rod at the center of piston upper surface, push rod upper end, which is bolted and fixed with, to push away
Handle, the both ends that push handle stretches out sliding groove are equipped with push-pull ring, and the limit plate is elliptical flat-plate, are equipped with limit at limit plate center
Hole is inserted with puncture needle body in limit hole, and limit board ends are symmetrically arranged with threaded hole, and the handle both ends, which are symmetrically bolted and fixed with, stretches
Contracting bar, telescopic rod front end, which is spirally connected, to be fixed in the threaded hole of limit plate, and clamping screw is equipped in the middle part of telescopic rod.The present apparatus is using
When, it can be adjusted according to the needs telescopic rod and stretch and be fixed by clamping screw, so that limit plate be made to be fixed on required length
On the puncture needle body of degree, handle is at T-shaped with puncture tube, is convenient for hand-held, will directly puncture needle body and firmly penetrates periosteum, limits
Plate can control paracentesis depth, when bone marrow extraction liquid, hold handle, index finger and middle finger protrude into push-pull ring, post-tensioning push handle
Bone marrow fluid is sucked out, the outer dynamics pulled out will not be generated to needle body is punctured in aspiration procedure, suction is stablized, and is convenient for control dynamics, is made
With conveniently.
Beneficial effect possessed by the utility model is: the structure design of the utility model is reasonable, passes through the use of limit plate
Can control paracentesis depth, handle and puncture tube it is at T-shaped convenient for hand-held and control dynamics, push-pull ring is used cooperatively in handle,
Suction action will not generate external broach degree to needle body is punctured, easy to use convenient for control extracting force, time saving and energy saving.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model.
Attached drawing 2 is the structural schematic diagram of the limit plate of the utility model.
Specific embodiment
With reference to the accompanying drawing 1, attached drawing 2 is described below the utility model.
As shown in Figure 1 and Figure 2, the utility model includes puncture tube 1, handle 3, punctures needle body 2, limit plate 12, telescopic rod 5,
1 lower end of puncture tube, which is bolted and fixed with, punctures needle body 2, and 1 upper end of puncture tube is bolted and fixed with handle 3,1 lower half portion of puncture tube
Outer tube wall is equipped with graduation mark 11, and 1 top half two sides of puncture tube are symmetrically arranged with sliding groove 14, are equipped with piston 7 in puncture tube 1,
Push rod 8 is bolted and fixed at 7 upper surface center of piston, 8 upper end of push rod is bolted and fixed with push handle 9, and push handle 9 stretches out sliding groove 14
Both ends are equipped with push-pull ring 10, and the limit plate 12 is elliptical flat-plate, are equipped with limit hole 4,4 interpolation of limit hole at 12 center of limit plate
Having and punctures needle body 2,12 both ends of limit plate are symmetrically arranged with threaded hole 13, and 3 both ends of handle are symmetrically bolted and fixed with telescopic rod 5,
5 front end of telescopic rod, which is spirally connected, to be fixed in the threaded hole 13 of limit plate 12, and clamping screw 6 is equipped in the middle part of telescopic rod 5.The present apparatus makes
Used time can be adjusted according to the needs telescopic rod 5 and stretch and be fixed by clamping screw 6, so that limit plate 12 be made to be fixed on
On the puncture needle body 2 of required length, handle 3 and puncture tube 1 are at T-shaped, are convenient for hand-held, will directly puncture needle body 2 and firmly wear
Deep film, limit plate 12 can control paracentesis depth, when bone marrow extraction liquid, hold handle 3, index finger and middle finger protrude into push-pull ring 10
In, bone marrow fluid can be sucked out for post-tensioning push handle 9, will not generate the dynamics pulled out outside to needle body 2 is punctured in aspiration procedure, suction is steady
It is fixed, it is convenient for control dynamics, it is easy to use.
