Problems solved by technology

The ligation device with this structure can only ligate one rubber ring at a time, and it needs to be reinstalled before the ligation is completed once, which is less efficient. It is necessary to carry out the pressure adsorption of hemorrhoids each time when installing the ring, which will cause certain discomfort to the patient

Abstract

The invention relates to a continuous emission mechanism of a haemorrhoids loop ligature device.The continuous emission mechanism is characterized by comprising a fixed pipe (1), a pushing pipe (2) and an emission trigger (3), the fixed pipe (1) is sleeved with the pushing pipe (2), the tail of the pushing pipe (2) is connected with the emission trigger (3) through a pushing rod (4), a compressed spring (5) is arranged on the pushing rod (4), and the pushing pipe (2) can move along the fixed pipe (1) back and forth by triggering the emission trigger (3); a fixed threaded rod (6) is arranged on the head of the fixed pipe (1), pushing threaded rods (7) are arranged on the head of the pushing rod (2), multiple slide grooves are uniformly formed in the fixed threaded rod (6), and the pushing threaded rods (7) are embedded into the slide grooves in the fixed threaded rod (6).The fixed threaded rod and the pushing threaded rods which are embedded inside and outside are adopted in the head of the loop ligature device to continuously emit rubber rings, and the haemorrhoids loop ligature device is suitable for treating different patients.

Description

technical field [0001] The invention relates to a hemorrhoid ligation device, in particular to a continuous firing mechanism of the hemorrhoid ligation device. It belongs to the technical field of medical devices. Background technique [0002] Hemorrhoid ligation is a common method for the treatment of hemorrhoids, and it has a good effect on ordinary hemorrhoids. However, the current clinical practice of hemorrhoid ligation is usually performed by the operator with bare hands under local anesthesia or other anesthesia, which is not only time-consuming, laborious, difficult to reveal, but also easy to cause bleeding and pain. In order to reduce the pain of patients and the difficulty of surgery, people have thought of a variety of methods for improvement, such as the negative pressure suction ligation method, which consists of a negative pressure suction head, a negative pressure generator and a connecting tube. The hemorrhoids are sucked into the negative pressure suction...
