Embodiment 1

[0039] refer to Figure 1 to Figure 7 As shown, this embodiment provides a multi-chamber ligation head, which is suitable for anorectal ligation; including: a plurality of negative pressure suction ports 1 and a plurality of ferrules corresponding to the plurality of negative pressure suction ports 1 one by one A firing block, and a pushing block adapted to simultaneously push a plurality of ferrule firing blocks.

[0040] Next, an optional implementation will be described with reference to the accompanying drawings. In this embodiment, the case where the multi-chamber ligation head includes three negative pressure suction ports 1 and three ferrule firing blocks is taken as an example. For three negative pressure suction ports 1, example with a kind of preferred situation, three negative pressure suction ports 1 are distributed evenly along the circumference of the outer side wall of negative pressure suction pipe 7, like this, three negative pressure suction The included ang...

Embodiment 2

[0048] see Figure 1 to Figure 7 As shown, on the basis of the multi-chamber ligation head of embodiment 1, this embodiment provides an anorectal ligation device, comprising: the multi-chamber ligation head of embodiment 1, the vacuum suction tube 7 The firing push rod 17 adapted to push the push block on the outer wall, and the handle structure 11 is provided at the end of the firing push rod 17 away from the push block.

[0049] Considering that the anorectal ligation device of this embodiment can accurately grasp the firing time during use, the handle structure 11 is provided with a firing handle 12 that is suitable for firing the firing push rod 17 of this embodiment, and is connected with the negative pressure suction tube 7 A firing indication assembly connected at one end protruding into the handle structure 11. That is, the medical staff can know the progress of the vacuum suction of the vacuum suction tube 7 by triggering the indicating component.

Abstract

The invention relates to a multi-cavity ligation head and an anorectal ligation device using the multi-cavity ligation head; the multi-cavity ligation head comprises a plurality of negative pressure suction ports, a plurality of loop percussion blocks and a pushing block, and the plurality of negative pressure suction ports are all communicated with a negative pressure suction tube of the anorectal ligation device; the plurality of ferrule percussion blocks are arranged on the outer side walls of the plurality of negative pressure suction ports in a sleeving manner in a one-to-one correspondence manner; the pushing block is arranged on the outer side wall of the negative pressure suction tube in a sleeving mode and suitable for pushing the multiple ferrule percussion blocks at the same time. The multi-cavity ligation head can effectively improve the ligation efficiency in an operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-chamber ligation head and an anorectal ligation device using the multi-chamber ligation head. Background technique [0002] Anorectal hemorrhoids, commonly known as hemorrhoids, are common and frequently-occurring diseases unique to humans. According to relevant census data, the incidence rate of anorectal diseases is 59.1%, and hemorrhoids account for 87.25% of all anorectal diseases, and among them, internal hemorrhoids are the most common, accounting for 52.19% of all anorectal diseases. Both men and women can get the disease, the incidence rate of women is 67%, and the incidence rate of men is 53.9%. It can occur at any age, and it will gradually increase with age, so there is a saying of "nine hemorrhoids out of ten". General surgical treatment for hemorrhoids includes ligation, rubber band ligation, and hemorrhoidectomy. Among them, for the rubber ring lig...
