Problems solved by technology

like figure 1 The existing cone expander shown has a pointed end at one end and a suction cup at the other end, but its surface is smooth, which makes the resistance of the rubber ring when it moves on the expander very large. very inconvenient
Moreover, the rubber ring is very easy to slip off from the cone expander or fall into the gap between the suction cup and the cone expander, resulting in the failure of the upper rubber ring

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 and figure 2 As shown, the structure diagram and the use state diagram of the existing cone expander are provided respectively, which include the expansion cone body 14 and the connecting part 3. expansion. figure 2 The gap 5 of indefinite size will be formed between the cone expander shown in and the suction cup 6. In the process of using the existing cone expander, after the rubber ring 4 is set on the head position of the expander cone 14, due to the expansion The outer surface of the vertebral body 14 is a smooth surface. When the medical staff pushes the apron, if the hand of the medical personnel separates from the apron, the apron will easily fall to the ground. Along with the movement of the rubber ring 4 on the expanded cone body 14, the friction force between the rubber ring 4 and the outer surface of the expanded ...

Abstract

The invention relates to a reamer for a loop ligature rubber ring, comprising a tip part, a middle part and a connecting part. The middle part is connected with the tip part and has a gradually increased cross section radius, and the connecting part is used for matching a sucker. The reamer for the loop ligature rubber ring is characterized in that at least three main supporting ribs are arranged and uniformly distributed on the outer surface of the middle part along the axis direction, and auxiliary supporting ribs can be arranged at both sides of each main supporting rib. By arranging the main supporting ribs, the friction force between the rubber ring and the reamer is effectively reduced so that a medical staff can save time and labor when arranging the rubber ring on the middle part by utilizing the reamer, and the rubber ring and gloves are prevented from winding when the rubber ring is manually arranged. The reamer for the loop ligature rubber ring is also provided with an extending part which is connected with the main supporting ribs and the auxiliary supporting ribs and arranged above the connecting part to effectively prevent the rubber ring from falling into a gap between the reamer and the middle part.

Description

technical field [0001] The invention relates to a cone expander for a rubber ring, and more specifically, to a cone expander for a rubber ring in which a supporting rib is provided on the outer surface of the expander to support the rubber ring. Background technique [0002] The patent number is 200920030932.5, the invention name is "Medical multi-energy suction injection ligation device", and the patent number is 200520081522.5, the invention name is "Medical multi-energy suction injection ligation device", the above two The patents all disclose a suction-injection ligation device. In the process of using the suction-injection ligation device, firstly, the rubber ring used for treating internal and external hemorrhoids needs to be ligated on the outer surface of the suction cup, and then the suction-injection ligation device is used to bind the The rubber band is ligated over the hemorrhoid. Since the inner diameter of the existing medical rubber ring is very small, genera...
