Description
Technical field
The utility model relates to the field of medical instrument technology, specially a kind of marrow puncture device.
Background technique
Bone marrow puncture is to acquire a kind of common diagnostic techniques of bone marrow fluid, and clinically bone marrow aspiration liquid is usually used in haemocyte
Morphological examination, it can also be used to candidate stem cell culture, CYTOGENETIC ANALYSIS OF ONE and Pathogen Biology inspection etc., to assist clinic
Diagnosis, observation curative effect and judging prognosis etc., have great importance in clinic.
Since human body bone is harder, when puncturing, medical staff often requires to use biggish strength, and traditional is similar to
The puncture needle of syringe needle is often unfavorable for medical staff's operation, and reliability is poor, operates time-consuming and laborious.Though
So also occur the puncture needle that part facilitates gripping on the market, but handgrip is usually all smaller, and fixes and connect with needle body
It connects, is not easy to subsequent sampling operation.
Utility model content
The purpose of this utility model be in view of the above shortcomings of the prior art, provide a kind of structure it is simple, it is easy to operate, save
Power, safety and stability, and conveniently remove the marrow puncture device of handgrip.
It is for technical solution used by realization the purpose of this utility model: a kind of marrow puncture device, including puncture needle
And holding mechanism, the puncture needle tail end have box structure, the holding mechanism has corresponding with the box structure
Card slot and the puncture needle are clamped.
At the top of the box structure and/or bottom margin has flange periphery, and the card slot side wall has and box structure
The corresponding chuck in side.
The holding mechanism generally ellipsoidal structure, is docked by the two parts being flexibly connected, is arranged between two parts
Tensioned spring and anticreep locating part, the card slot is between two-part faying face, box structure described in clamping when docking.
The two sides of the holding mechanism are laid with finger slot.
It is arranged with positioning sleeve on the puncture needle and is threaded with limit thumb wheel.
The side wall of the positioning sleeve is provided with non slip surface, and lower end is flange base portion, and the bottom surface in flange base portion is arranged
There is the medical silica-gel with certain viscosity.
The marrow puncture device of the utility model is by being arranged box structure and holding mechanism clamping, side in puncture needle tail end
Just unloading for holding mechanism takes, and greatly facilitates puncture and the sampling operation of medical staff.Holding mechanism is docked using two parts
Ellipsoidal structure, and realized under non-operating state by tension spring and anticreep locating part, protect open configuration, in use,
Only needing to hold with a firm grip can be by puncture needle clamping, after puncture, and hand one unclamps, and opens, can remove from puncture needle naturally, very simple
Just, meanwhile, holding mechanism two sides are laid with finger slot, facilitate gripping, human oriented design.When positioning sleeve is by being convenient for puncturing on the one hand
Positioning and control puncture direction, on the other hand keep stablizing convenient for puncture needle after puncture, and match with limit thumb wheel, and realization is worn
Thorn depth accurately controls.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing:
Fig. 1 is the overall structure diagram of the utility model embodiment；
Fig. 2 is the structural schematic diagram of the utility model holding mechanism；
Fig. 3 is the structural schematic diagram in Fig. 1 at A-A；
Fig. 4 is the enlarged structure schematic diagram of half of card slot in the utility model embodiment；
Fig. 5 is the top cross section structure schematic diagram of puncture needle.
Specific embodiment
It is as shown in Figs. 1-5: a kind of marrow puncture device, including puncture needle 8 and holding mechanism 4, the tail end of the puncture needle 8
With box structure 13, the pin hole of puncture needle 8 runs through the box structure 13, and the holding mechanism 4 has and the square knot
The corresponding card slot 2 of structure 13 and the box structure 13 of the puncture needle 8 are clamped.
Positioning sleeve 9 and limit thumb wheel 7 are arranged on the puncture needle 8, positioning sleeve 9 is located at the lower part of puncture needle 8, puncture needle
8 can slide axially in positioning sleeve 9 along it, the top of puncture needle 8, as shown in figure 5, there is planar structure, edge at planar structure
The axial direction of puncture needle 8 is provided with the graduation mark 6 of display paracentesis depth, while the top of puncture needle 8 has screw thread, limits thumb wheel 7
It is threadedly coupled with puncture needle 8, realizes that the adjusting to paracentesis depth controls by adjusting limit thumb wheel 7.The side wall of the positioning sleeve 9
It is provided with non slip surface 10, facilitates medical staff's grip, keeps stablizing, the lower end of positioning sleeve 9 is flange base portion 11, flange base
The bottom surface in portion 11 is provided with the medical silica-gel 12 with certain viscosity, convenient to keep being steadily contacted with patient skin.
Referring to Fig. 2, the holding mechanism 4 generally ellipsoidal structure, and be laid in its two sides and refer to slot 1, holding mechanism 4
It is docked, tension spring 16 is provided between two parts and prevented by the first half portion 14 and 17 two parts of the second half portion that are flexibly connected
De- locating part 15, tension spring 16 press against between the first half portion 14 and the second half portion 17 in corresponding spring indent, to first
Half portion 14 and the second half portion 17 form press opening trend, anticreep locating part 15 include the mast being arranged in the second half portion 17 and
Anticreep sliding slot corresponding with mast, mast is arranged in the first half portion 14 to be inserted in anticreep sliding slot, mast top has anti-
Off card platform.
The card slot 2 is between the first half portion 14 and the two-part faying face of the second half portion 17, respectively at the first half portion 14
With half of card slot is set in the second half portion 17, when docking, forms whole card slot, box structure 13 described in clamping.
Further, 13 top of box structure and/or bottom margin have flange periphery 5, and the present embodiment is using top
Flange periphery 5 is arranged in portion and bottom simultaneously, and the side wall of the card slot 2 has chuck 3 corresponding with 13 side of box structure, card
When connecing, chuck 3 is between upper and lower flange periphery 5.
When the utility model is used, paracentesis depth is set by adjusting limit thumb wheel 7, by the box structure of puncture needle 8
13 are connected in card slot 2, and medical staff holds holding mechanism 4 on the other hand, and another hand steered stable position set 9 firmly presses holding mechanism
4, the smooth puncture of puncture needle 2 can be realized, after puncture, unclamp holding mechanism 4, box structure 13 can be detached from card slot 2, then
Marrow sampling can be carried out by sampling injector.It is safe and simple, time saving, laborsaving.
The technical solution of the utility model is not restricted in the range of embodiment described in the utility model.This is practical new
