TECHNICAL FIELD
[0001] The present application relates to a medical instrument, in particular to a cleaning device for a triangular knife of a digestive endoscope accessory. BACKGROUND
[0002] The triangular knife of a digestive endoscope accessory is a device used in super minimally invasive surgery under a digestive endoscope. The handle of the triangular knife is connected to an electrotome machine. When the triangular knife cuts tissues, the burnt tissue and mucus generated will stick to the triangular knife. When the burnt tissue and mucus on the triangular knife are too much, the cutting effect will be reduced. Therefore, the triangular knife is often pulled out of the biopsy channel of the endoscope for cleaning during the operation. The triangular knife includes a knife head and an elongated connecting rod. The knife head is perpendicularly installed at the end of the connecting rod. At present, there is a lack of special cleaning tools in clinical practice. The commonly used method is to scrape off the burnt tissue on the front and back of the knife head with a scalpel blade. Both the triangular knife and the scalpel blade are sharp and can easily injure the hand. In addition, the triangular knife is very small and the scraping speed is slow. CONTENT OF THE UTILITY MODEL
[0003] In view of the above problems, the present application aims to provide a cleaning device for a triangular knife of a digestive endoscope accessory, which can conveniently and quickly remove the burnt tissue on the triangular knife and is not easy to injure the operator's hand.
[0004] The cleaning device for a triangular knife of a digestive endoscope accessory of the present application comprises a pipe body.
[0005] The first end and the second end of the pipe body are both closed by end caps. A T-shaped groove is formed on the peripheral surface of the pipe body. The T-shaped groove includes a horizontal extension and a vertical extension. The horizontal extension penetrates the side wall of the pipe body, and the vertical extension penetrates the side wall of the pipe body and forms a notch on the end cap of the second end of the pipe body. The horizontal extension of the T-shaped groove is used to provide a channel for the knife head of the triangular knife to enter the pipe body, and the vertical extension of the T-shaped groove is used to provide a channel for the connecting rod of the triangular knife to enter the pipe body.
[0006] A plurality of first steel wires are densely arranged on the inner side of the end cap of the first end of the pipe body. The first end of the first steel wire is fixed on the inner side of the end cap of the first end of the pipe body, and the second end points to the end cap of the second end of the pipe body. A plurality of second steel wires are densely arranged on the inner peripheral surface of the pipe body. The first end of the second steel wire is fixed on the inner peripheral surface of the pipe body, and the second end obliquely points to the axis of the pipe body and extends to the vicinity of the axis of the pipe body. For the same second steel wire, the second end is closer to the first end of the pipe body than the first end.
[0007] The first steel wire is used to clean the first side of the tool head, and the second steel wire is used to clean the second side of the tool head and the circumferential surface of the connecting rod of the triangular knife.
[0008] Preferably, a handle is integrally formed on the outer side of the end cover of the first end of the pipe body, and the handle is formed in a cylindrical shape, and the circumferential surface thereof is formed rough.
[0009] Preferably, the transverse extension of the T-shaped groove is located at two-thirds of the axial height of the pipe body.
[0010] Preferably, the first steel wire is perpendicular to the end cover of the first end of the pipe body, and the second steel wire forms an angle of 45 degrees with the axis of the pipe body.
[0011] The cleaning device for the triangular knife of the digestive endoscope accessory of the present application can simultaneously brush off the debris and tissues on both sides of the triangular knife through the steel wires in the pipe body, and the triangular knife is accommodated in the pipe body and does not expose outside, so that the user can safely, quickly and conveniently clean the triangular knife.

DETAILED DESCRIPTION
[0015] The cleaning device for the triangular knife of the digestive endoscope accessory of the present application comprises a pipe body 10.
[0016] The first end and the second end of the pipe body 10 are closed by end covers; a T-shaped groove 11 is formed on the circumferential surface of the pipe body 10; the T-shaped groove 11 comprises a transverse extension and a longitudinal extension; the transverse extension penetrates the side wall of the pipe body, and the longitudinal extension penetrates the side wall of the pipe body and forms a notch on the end cover of the second end of the pipe body; the transverse extension of the T-shaped groove 11 is used to provide a channel for the tool head of the triangular knife to enter the pipe body, and the longitudinal extension of the T-shaped groove 11 is used to provide a channel for the connecting rod of the triangular knife to enter the pipe body.
[0017] The inner side of the end cover of the first end of the pipe body 10 is densely provided with a plurality of first steel wires 14; the first end of the first steel wire 14 is fixed on the inner side of the end cover of the first end of the pipe body, and the second end points to the end cover of the second end of the pipe body; a plurality of second steel wires 15 are densely provided on the inner circumferential surface of the pipe body 10 around the inner circumferential surface of the pipe body 10, the first end of the second steel wire 15 is fixed on the inner circumferential surface of the pipe body, the second end of the second steel wire 15 is obliquely directed to the axis of the pipe body and extends to the vicinity of the axis of the pipe body, and for the same second steel wire 15, the second end is closer to the first end of the pipe body than the first end.
[0018] The tool bit accommodating space 13 is formed between the plurality of first steel wires 14 and the plurality of second steel wires 15; the tool bit accommodating space 13 is opposite to the transversely extending part of the T-shaped groove; for the tool bit entering the tool bit accommodating space 13, the first steel wire 14 is used to clean the first side thereof, and the second steel wire 15 is used to clean the second side thereof and the circumferential surface of the connecting rod of the triangular knife.
