Description
Technical field
The utility model is a kind of Cardiological sting device, belongs to technical field of medical instruments.
Background technology
Hydropericardium is a kind of common Cardiological disease, and at present, the treatment method of hydropericardium is mainly uses puncture needle
Extracted out by paracentesis pericardii and by hydrops, but, existing puncture needle is when pericardium is punctured, it is difficult to grasp paracentesis depth, together
When ceaselessly beated due to heart, injury of myocardium is easy in extraction process.
Utility model content
In view of this, the utility model purpose is to provide a kind of Cardiological sting device, and simple structure can be adjusted and locked
Determine paracentesis depth, while extracting hydropericardium steadily, do not result in patient uncomfortable.
To achieve these goals, the utility model is realized by the following technical solutions：A kind of Cardiological punctures dress
Put, including puncture needle, also including the keeper, negative pressure suction device and the connecting puncture needle that are set on puncture needle and vacuum suction
The flexible pipe of device, the keeper includes the locating piece being slidably located on puncture needle and for carrying out slide lock to locating piece
Lock screw.
Further, the negative pressure suction device includes cylinder, fairlead, piston and piston rod, and described cylinder one end sets
There is the nipple connected with cylinder, the other end is coaxially provided with fairlead, and the nipple is connected with flexible pipe, the piston is located at cylinder
Interior, described piston rod one end is connected with piston, and the other end is stretched out in outside cylinder through fairlead, and piston rod is matched somebody with somebody with external threading is oriented to
Close.
Further, it is provided with valve on the nipple.
Further, the locating piece includes tapered portion and is arranged on the cylindrical portion of the tapered portion rear end, the locking
Screw is arranged in cylindrical portion.
The beneficial effects of the utility model：A kind of Cardiological sting device of the present utility model, including puncture needle, also include
The flexible pipe of the keeper, negative pressure suction device and connecting puncture needle and negative pressure suction device that are set on puncture needle, the positioning
Part includes the be slidably located in locating piece on puncture needle and the lock screw for carrying out slide lock to locating piece.The structure
Cardiological sting device, simple structure can adjust and lock paracentesis depth, while extracting hydropericardium steadily, not result in
Patient is uncomfortable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
For technological means, creation characteristic, reached purpose and effect for realizing the utility model are easy to understand, below
With reference to specific embodiment, the utility model is expanded on further.
Fig. 1 is referred to, the utility model provides a kind of technical scheme：A kind of Cardiological sting device, including puncture needle 1,
Also include the flexible pipe of keeper, negative pressure suction device 5 and connecting puncture needle 1 and the negative pressure suction device 5 being set on puncture needle 1
4, the keeper includes the be slidably located in locating piece 2 on puncture needle 1 and the locking for carrying out slide lock to locating piece 2
Screw 3.Scale is provided with puncture needle 1, when specifically used, locating piece 2 is pushed corresponding scale by the situation according to patient
Corresponding position, carries out puncture procedure, then by flexible pipe 4 and negative pressure after then locating piece 2 is locked by lock screw 3 again
Suction device 5 suctions out hydropericardium.Due to suctioning out when hydropericardium, both hands of medical personnel and not in contact with puncture needle 1,
So puncture needle 1 is beated with heart same frequency, and cardiac muscle is caused to damage so as to avoid.
Used as the further improvement of such scheme, the negative pressure suction device 5 includes cylinder 51, fairlead 54, piston 52
With piston rod 53, the one end of the cylinder 51 is provided with the nipple 511 connected with cylinder 51, and the other end is coaxially provided with fairlead 54, institute
State nipple 511 to be connected with flexible pipe 4, the piston 52 is located in cylinder 51, and the one end of the piston rod 53 is connected with piston 52, another
End is stretched out in outside cylinder 51 through fairlead 54, and piston rod 53 coordinates with the screw thread of fairlead 54.When extracting hydropericardium, rotate and live
Stopper rod 53, so that band piston 52 is moved along the axis direction of cylinder 51, this avoid directly along the pulling of the axis direction of cylinder 51
May be because pulling piston rod 53 too fast and the patient brings discomfort during piston rod 53.
As the further improvement of such scheme, valve 55 is provided with the nipple 511.Needs are installed when cylinder 51 is interior
After the hydropericardium of extraction, valve 55 is closed, then take negative pressure suction device 5 away, it is easy to operate.
Used as the further improvement of such scheme, the locating piece 2 includes tapered portion and is arranged on the tapered portion rear end
Cylindrical portion, the lock screw 3 is arranged in cylindrical portion.Punctured sometimes for certain angle is inclined due to puncture needle 1,
Tapered portion can be well adapted for the change of the angle of puncture needle 1, and cylindrical portion is easily installed lock screw 3.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above, for
For those skilled in the art, it is clear that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and without departing substantially from this
In the case of the spirit or essential attributes of utility model, the utility model can be in other specific forms realized.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is by institute
Attached claim is limited rather than described above, it is intended that will fall in the implication and scope of the equivalency of claim
All changes are included in the utility model.Any reference in claim should not be considered as the right involved by limitation
It is required that.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each implementation method is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Specification an as entirety, the technical scheme in each embodiment can also be formed into those skilled in the art through appropriately combined
May be appreciated other embodiment.
