Problems solved by technology

[0002] Most of the existing traditional puncture devices are composed of the following parts, namely, sheath, puncture needle, ventilation valve and integrated conversion sleeve retractable valve; it is not difficult for doctors to find in clinical use that when the puncture needle or other instruments repeatedly When moving on the retractable valve of the integrated conversion sleeve, the device will not move smoothly, causing certain troubles to the doctor's operation
In order to solve this similar phenomenon, it is necessary to increase the lubricating medical silicone oil or apply silicone oil on the valve in advance to achieve the lubricating effect, which will cause excessive redundant operations for production or doctor use.

Abstract

The invention relates to a self-lubricating disposable puncture device. The self-lubricating disposable puncture device comprises a puncture sleeve, a shell and a core rod, wherein the shell is connected with the upper end of the puncture sleeve, and the core rod is provided with a core rod seat at the upper end; the shell sequentially comprises a switching cap and a sleeve seat from top to bottom, the switching cap is matched with the sleeve seat in a sealed manner, the sleeve seat is arranged at the upper end of the puncture sleeve and integrally connected with the puncture sleeve, and the central axis of the puncture sleeve, the sleeve seat and the switching cap is provided with a working channel allowing a surgical instrument or the core rod to penetrate. The self-lubricating disposable puncture device further comprises a lubricating component arranged on the working channel. The lubricating component contacts with the surgical instrument or the core rod to lubricate the surgical instrument or the core rod. The self-lubricating disposable puncture device is simple in structure, convenient to operate and capable of fast lubricating the instrument.

Description

technical field [0001] The invention relates to a self-lubricating disposable puncture device. Background technique [0002] Most of the existing traditional puncture devices are composed of the following parts, namely, sheath, puncture needle, ventilation valve and integrated conversion sleeve retractable valve; it is not difficult for doctors to find in clinical use that when the puncture needle or other instruments repeatedly When moving on the retractable valve of the integrated conversion sleeve, the device will not move smoothly, which will cause certain troubles to the doctor's operation. In order to solve this similar phenomenon, it is necessary to increase the lubricating medical silicone oil or smear the silicone oil on the valve in advance to achieve the lubricating effect during use, which will cause too redundant operations for production or doctor use. Contents of the invention [0003] The object of the present invention is to provide a self-lubricating dis...
