Problems solved by technology

Suction ligation devices can be divided into two types: electric suction ligation devices and manual suction ligation devices. The former has strong suction and sufficient suction due to the negative pressure generated by the negative pressure pump, but its disadvantage requires a heavy load. Pressure pump, not only high equipment cost, but also inconvenient to use
Although the manual suction ligation device currently used does not require a negative pressure pump and is simple to install, the negative pressure generated by it is relatively small, and the suction effect is not as good as that of the electric suction ligation device, and the negative pressure value is not displayed

Abstract

The invention discloses a haemorrhoids loop ligature device. The haemorrhoids loop ligature device comprises a main system, a loop ligature operation system and a vacuum aspiration operation system. The three systems are ingeniously combined to form the haemorrhoids loop ligature device, negative pressure meeting clinical needs can be generated without a negative pressure pump, the negative pressure value can be displayed, more functions are realized, and using is more convenient.

Description

technical field [0001] The invention relates to a ligation device for treating hemorrhoids. Background technique [0002] Hemorrhoid ligation is a commonly used and effective method for the treatment of internal hemorrhoids. It has the characteristics of economy, simplicity and reliable curative effect. No hospitalization is required, and it can be performed in outpatient clinics and clinics. Hemorrhoid ligation devices are generally divided into two categories: traction ligation and suction ligation. At present, the most popular method is to attract ligation. Suction ligation devices can be divided into two types: electric suction ligation devices and manual suction ligation devices. The former has strong suction and sufficient suction due to the negative pressure generated by the negative pressure pump, but its disadvantage requires a heavy load. The pressure pump not only has high equipment cost, but also is inconvenient to use. Although the currently used manual suc...
