Technical field

The present invention relates to a kind of visual Pericardiopuncture needle and its application methods, belong to the field of medical instrument technology.

Background technique

Paracentesis pericardii is the Clinics that cavum pericardiale is directly pierced by puncture needle.Paracentesis pericardii must be under asptic technique It carries out, the anesthesia of topical application procaine, site of puncture can not be too deep, makes in order to avoid puncturing atrium, ventricle or puncturing coronary artery At a large amount of hematoceles of cavum pericardiale.Paracentesis pericardii patient can understand the property of hydropericardium, and root by the liquid in chemical examination cavum pericardiale The cause of disease of pericarditis is found out according to the property of hydropericardium.It is mainly saturating by B ultrasound in current paracentesis pericardii surgical procedure Depending on thoracic cavity, then puncture needle is operated to perform the operation, but due to the limitation of B ultrasound, it is easy to cause to puncture atrium, ventricle or thorn Partially, success rate of operation is to be improved.

Summary of the invention

The technical problem to be solved in the present invention, is to provide a kind of visual Pericardiopuncture needle, which is equipped with mirror Sheath, by being equipped with miniature webcam in mirror sheath end, so that puncture process is in visualization, success rate of operation is greatly improved.

The present invention is realized by following proposal: a kind of visual Pericardiopuncture needle comprising mirror sheath, puncture needle, is led at puncture outfit Silk and indwelling tube, the mirror sheath are formula structure up and down, and the puncture outfit and the puncture needle activity insertion mirror are intrathecal, The puncture needle is cavity structure, and the seal wire activity is inserted into the puncture needle, and the indwelling tube is cavity up and down Structure, the indwelling tube are actively set on the outside of the seal wire.

Successively to be inserted into the mirror intrathecal for activity for the puncture outfit and the puncture needle, and does not coexist the mirror is intrathecal.

The side connection seal wire of the puncture needle upper end is inserted into head, and seal wire insertion head is also cavity structure, and with institute It states puncture needle to be connected, activity passes through the puncture needle after the seal wire activity passes through seal wire insertion head.

The seal wire insertion head is upward incline structure.

The left side lower end of the mirror sheath connects miniature webcam, and the miniature webcam is connected to display by connecting line Screen, the display screen are detachable and rotatable, left side side wall of the connecting line across the mirror sheath.

Cavity structure inside the mirror sheath is off-centre operation structure, and the cavity structure is close to the left side of the mirror sheath, institute The right side wall for stating mirror sheath is provided with sluice way, and upper end connects flow sub, the sluice way and the drainage on the right side of the mirror sheath Connector is connected.

The upper end of the puncture needle connects syringe adapter.

The puncture outfit is solid construction, has a diameter larger than the diameter of the puncture needle, and the puncture needle is tip.

A kind of application method of visual Pericardiopuncture needle, follows the steps below,

Step 1: mirror sheath is put into thoracic cavity, puncture outfit is intrathecal from upper end activity insertion mirror, and passes through mirror sheath, the puncture outfit Together with the mirror sheath deeply；

Step 2: the information of miniature webcam shooting is transmitted to display screen, judge whether mirror sheath reaches pericardium front end, reaches pericardium When front end, puncture outfit, activity insertion puncture needle are taken out；

Step 3: being penetrated in pericardium with puncture needle；

Step 4: by seal wire out of seal wire insertion head insertion puncture needle, and puncture needle is passed through, it is inserted into pericardium, seal wire reaches the heart Puncture needle is taken out after packet；

Step 5: by indwelling pipe sleeve on the outside of seal wire, and indwelling tube is imported into pericardium by seal wire, is finally taken out seal wire and is taken Appearance sheath completes the operation for placing indwelling tube.

It is described Step 1: Step 2: the blood generated during with step 3 is discharged from sluice way.

The invention has the benefit that

1, mirror sheath is first put into thoracic cavity by a kind of visual Pericardiopuncture needle of the present invention when in use, puncture outfit is being combined, so that mirror Sheath reaches pericardium front end, then takes out puncture outfit, then penetrated in pericardium with puncture needle, can use appearance sheath at this time, in puncture needle It is put into seal wire, seal wire takes out puncture needle after reaching pericardium, then indwelling tube is imported into pericardium along seal wire, finally takes out and leads Silk completes the operation for placing indwelling tube, due to being equipped with miniature webcam in mirror sheath end, so that whole process is in visual Change, success rate of operation greatly improves；

2, a kind of visual Pericardiopuncture needle mirror sheath of the present invention is equipped with sluice way, can will be generated in puncture process by sluice way Liquid is sucked out, and avoids superinfection.
