Problems solved by technology

[0002] The biopsy cap of the traditional endoscope is manually operated by people. The biopsy channel is closed or opened by using the biopsy cap. Manual operation is time-consuming during the inspection operation, and it is easy to cause gas in the inflated gastric cavity and intestinal cavity to escape. impact observation
When the biopsy equipment is taken out after the inspection, if the biopsy channel is not closed in time, the digestive products in the human stomach and intestines will be sprayed out, contaminating the operation table or the clothes of the operator

Embodiment Construction

[0011] as attached figure 1 As shown, the valve body 5 of the one-way valve 2 of the biopsy cap of the present invention is connected to the biopsy cap 1 through the pin 3; When performing endoscopic examination, the one-way valve 2 in the biopsy cap 1 is in a closed state due to the pressure of the gas in the human body; 2 There is a downward pressure, and the one-way valve 2 opens downward; when the test equipment is drawn out from the biopsy channel 7, gas or liquid will be ejected along the biopsy channel 7, and the air flow will generate upward pressure on the one-way valve 2 , the one-way valve 2 automatically closes to the position where the block 4 is located under the action of the air flow pressure.

[0012] as attached figure 2 Shown is the biopsy cap 1 of the second embodiment of the present invention, which differs from the biopsy cap 2 of the first embodiment in that a spring 8 is provided on the pin 3 of the fixed check valve 2, and one end of the spring 8 i...

Abstract

The invention discloses a biopsy cap used for closing an endoscope biopsy channel. The one-way valve that is provided with in the biopsy cap. The valve body of the one-way valve is connected on the biopsy cap by pins. When the biopsy equipment is inserted into the biopsy cap, force will be applied to the one-way valve, and the one-way valve will open; when the biopsy equipment is withdrawn, the pressure of the gas in the human gastric cavity and intestinal cavity will automatically close the one-way valve. Thereby reducing human manual operations and effectively preventing gas or liquid splashing in the body cavity. A slender channel is attached to the inner edge of the biopsy cap. The upper end of the channel extends out of the biopsy cap, and the lower end of the channel is inserted into the biopsy channel and extends to its opening. Biopsy and drug or lotion can be injected at the same time, which solves the problem of the original biopsy and injection. Problems with medicines or lotions that don't work together.

Description

technical field [0001] The invention is a biopsy cap of an endoscope, which is used for closing the biopsy channel of the endoscope. Background technique [0002] The biopsy cap of the traditional endoscope is manually operated by humans. The biopsy channel is closed or opened by using the biopsy cap. Manual operation is time-consuming during the inspection operation, and it is easy to cause gas in the inflated gastric cavity and intestinal cavity to escape. Impact Observation. When the biopsy equipment is taken out after the inspection, once the biopsy channel is not closed in time, the digestive substances in the stomach and intestines of the human body will be ejected, polluting the operating table or the clothing of the operator. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a biopsy cap of an endoscope, which does not need to be manually opened when inserting biopsy equipment during biopsy; and can be aut...
