Problems solved by technology

However, due to the elastic limitation of the sealing cup, often, when the thorn bar passes through the sealing cup until it is pulled out from the sealing cup, the damage to the sealing cup is relatively large, and the original gap is greatly affected, so that The sealing cup cannot play the role of self-sealing well when it is inflated, causing air leakage, and cannot control the inflation pressure well, which will adversely affect the operation

Abstract

The invention relates to a disposable puncture importer which comprises an upper housing and a lower housing which enclose a cavity; a core is connected to the top of the upper housing and positioned in the cavity enclosed by the upper and the lower housings, a core outlet is formed at the bottom of the core, a movable plate is arranged in the cavity enclosed by the upper and the lower housings, one end of the movable plate is movably connected with the core, a first magnetic block and a second magnetic block which are attracted with each other are mounted on the movable plate and the core respectively, and the movable plate and the core outlet are sealed in a contacted manner through the adsorptive power between the first magnetic block and the second magnetic block. When the disposable puncture importer provided by the invention is in use, the core outlet of the disposable puncture importer can be well sealed, so that the inflation pressure is ensured, and the disposable puncture importer can not be damaged by a puncture rod.

Description

technical field [0001] The invention relates to the technical field of disposable medical devices, in particular to a disposable puncture introducer. Background technique [0002] In order to form a wound hole on the skin surface in the existing medical operation at present, pass through the core of the puncture introducer by using the thorn bar, pass through the piercing tube of the puncture introducer to reach the skin, and then pierce the skin to form a wound hole, and then pull out the thorn The rod inflates the wound to facilitate surgery. The outlet of the core of the common puncture introducer is usually set as a sealed cup with a cross or a zigzag gap. The natural elasticity of the sealing cup seals. However, due to the elastic limitation of the sealing cup, often, when the thorn bar passes through the sealing cup until it is pulled out from the sealing cup, the damage to the sealing cup is relatively large, and the original gap is greatly affected, so that Sealed...
