The present invention is adjustable Pericardiopuncture needle, and it includes being pierced into part, adjusts part；It is pierced into wherein described adjustment portion point comprising connection on the outside of the inner tube of part, regulation part inner tube and adjustment structure is set, adjustment structure includes a moving structure moved up and down；Scale is set in the adjustment structure, and adjustment structure is adjusted by upper and lower displacement to being pierced into partial-length；The adjustment structure includes being located at screw structural on the outside of inner tube and includes the moving structure of correspondence screw structural, and screw nut structure section sets one to include scale flat segments；Or it is to be arranged on the circular ring structure on the outside of inner tube and the moving structure on the outside of annulus to reconcile structure, scale is arranged on circular ring structure；Also delay comprising the less extension of a size moving structure front end.The present invention reaches that regulation is pierced into the purpose of partial-length by moving up and down moving structure, can meet the demand of different patients, rational in infrastructure, is convenient to using regulation.
Description
Technical field
The invention belongs to a kind of puncture needle that department of cardiac surgery's apparatus, particularly pericardicentesis are used, and in particular to be
Adjustable Pericardiopuncture needle.
Background technology
Hydropericardium is a kind of more typical clinical manifestation, is one of vital sign of pericardial disease, and hydropericardium is visible
In exudative pericarditis and other non-inflammation pericardium lesions, it can generally be determined through physical examination and x-ray inspection.For pericardium product
The clinical manifestation of liquid using Pericardiopuncture needle progress liquid drain or acquirement hydropericardium, it is necessary to be checked；Current pericardium
Need to detect by x-ray before puncture and determine to puncture the length being needled into, then drawn according to the Pericardiopuncture needle of length-specific model
Enter.
Because the fat or thin degree difference of patient is very big, it is necessary to the length penetrated also has very big difference in specific clinical process, and
The length of current puncture needle is all certain, and different length models, but type are set in order to meet the demand needs of different patients
Number limitednumber, and when specifically used selection get up it is very cumbersome；The setting of different model is difficult the need for meeting different patients
Will；And the length that penetrates of paracentesis pericardii must be accurate, the problem of otherwise easily occurring not reaching pericardium or wear out pericardium,
In turn result in some harm；Therefore it is in use to need medical personnel rule of thumb to be operated more, which increases
The operation difficulty of operator.
Therefore a kind of Pericardiopuncture needle for needing to carry out being pierced into length adjustment according to particular patient is needed, pericardium of the present invention is worn
There is provided adjustable Pericardiopuncture needle for the problem of pricker exists according to prior art.
The content of the invention
The problem of patient demand can not being met for the setting for the length model for overcoming prior art Pericardiopuncture needle, this hair
It is bright that adjustable Pericardiopuncture needle is provided.
Adjustable Pericardiopuncture needle, it includes being pierced into part, adjusts part；Connection thorn is included in wherein described adjustment portion point
Enter and adjustment structure is set on the outside of the inner tube of part, regulation part inner tube, adjustment structure includes a mobile knot moved up and down
Structure；Scale is set in the adjustment structure, and adjustment structure is adjusted by upper and lower displacement to being pierced into partial-length.The present invention is worn
The length for being pierced into part can be adjusted by entering length-adjustable Pericardiopuncture needle, be set according to the size of patient oneself, very
Accurately, the work difficulty of medical worker can effectively be reduced.
Further, the adjustment structure includes being arranged on screw structural section on the outside of inner tube and comprising correspondence screw structural
Comprising the flat segments without screw one in moving structure, screw structural section, scale is set in flat segments.The setting of flat segments
Effective observation to scale can be ensured, and screw structural setting can effectively realize the regulation to being pierced into partial-length.
Further, the adjustment structure includes the larger-size circular ring structure of circle being arranged on the outside of inner tube, annulus knot
Scale is set on structure, and the moving structure is arranged on the loop configuration on the outside of circular ring structure, moved up and down along circular ring structure.It is such a
Setting can facilitate the setting of scale, and the setting relative movement of two cyclic structures is also easier.Further, the movement
The raised structures for assisting moving structure to move up and down are set in structure.The convenient manipulation to moving structure of setting of raised structures.
Further, the material of the moving structure is foam or elastomeric material.Such a material is readily available, and can be with internal layer annulus
Close structure is contacted, and does not influence to move up and down.
Further, a bit of size is also set up below the moving structure slightly larger than the extension for being pierced into segment outer radius.
The setting of extension can be prevented effectively because top adjustment structure external diameter is larger and influences operation.
Further, the length range of the piercing part is 12-14cm, and the length range of the moving structure is 4-6cm.
It is such a to set the piercing length range that make piercing part by regulation in 8-14cm, substantially meet the demand of all patients.
Further, the linear module of the minimum dimension of the scale is mm.
Further, the length range of the piercing part is 12-14cm, and the length range of the moving structure is 4-6cm,
The length of the extension is 0.4-0.8cm.
Further, the scale is from distal-to-proximal insertion end, and scale value is tapered into, such a to set the quarter for ensureing to spill
Degree display is exactly the length that front end is pierced into part.
Further, the extension sets mark structure foremost.The setting of mark structure can realize the mark to front end
Note, carries out color mark on path during by moving down, top will be moved on to after being paused after specified location by reaching on moving structure, this
Sample can just understand the situation for being pierced into depth by the color of mark, it is possible to prevente effectively from the adjustment structure size of change is to being pierced into
The influence being partially penetrated into.Further, the mark structure is the sponge structure with dyestuff on the inside of extension.
Further, said inner tube opposite side connects a Y tube, and one is used to draw heart hydrops, and the other end is used for medicine
Thing is injected in vivo.
In use, regulation moving structure understands what is be pierced into the distalmost end of regulation part according to ultrasound diagnosis result first
After length, at mobile moving structure to suitable dimension, the length situation of front end is understood by observing the size in adjustment structure, is arrived
Stop after up to correct position, carry out penetrating for puncture needle.Apparatus to tagged architecture is, it is necessary to which road specific bit in road is postponed and retracted
To distalmost end.
Compared with prior art, adjustable Pericardiopuncture needle of the invention realizes the accurate adjustment for penetrating part, again can be right
Non-entry part is marked.
