Safety endovascular intervention treatment puncture channel expansion device

Abstract

The invention discloses a safety endovascular intervention treatment puncture channel expansion device. The safety endovascular intervention treatment puncture channel expansion device comprises rectangular frames, wherein rectangular air bags are fixedly connected to the bottoms of the rectangular frames; air boxes are fixedly connected to the opposite sides of the two rectangular frames; communicating pipes are fixedly connected to the opposite sides of the two air boxes; air pushing plates are slidably connected into the corresponding air boxes; a linkage rod is rotationally connected to the top of a deflection rod; a wind box is fixedly connected to the end, away from an air spring, of a ventilation pipe; an air blocking plate is arranged at the bottom of the ventilation pipe in a penetrating mode; an air leakage rod is arranged at the bottom of the ventilation pipe and located on the right side of the air blocking plate in a penetrating mode; a magnetic block is arranged below a force measuring rod; and a pressure rod is glidingly connected to the bottom of the magnetic block. According to the safety endovascular intervention treatment puncture channel expansion device, the air spring and the force measuring rod are used in cooperation, and therefore the effects of automatically adjusting the expansion force and preventing vascular injury during vasoconstriction are achieved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a safe puncture tract expansion device for intravascular interventional treatment. Background technique [0002] Interventional therapy comes from interventional radiology, using X-ray fluoroscopy, CT positioning, B-type ultrasound equipment and other medical imaging equipment as guidance, and passing special catheters or instruments through human arteries, veins, natural channels of the digestive system, biliary tract or after surgery. The drainage tube can reach the diseased area in the body to obtain tissue cells, bacteria or biochemical data, and can also perform imaging data to obtain imaging data, so as to achieve the purpose of diagnosing diseases and performing various special treatments at the same time. [0003] When performing blood vessel puncture treatment, it is necessary to use a vasodilator to build a puncture channel so that the catheter can pass through the blo...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a safe puncture tract expansion device for intravascular interventional therapy, which has the advantages of automatically adjusting the expansion force when the blood vessel contracts, preventing blood vessel damage, etc., and solving the problem of the existing expansion device in the blood vessel. The expansion force cannot be adjusted during contraction, which may cause damage to the contact surface between the blood vessel and the device, which is unfavorable to the healing of the blood vessel after puncture
