Minimally invasive adenoid ablation device

Abstract

The minimally invasive adenoid eliminating device can solve the problem that the size is limited when the device enters the nasopharyngeal cavity; the whole structure of the device can be contracted; the device enters the nasopharyngeal cavity after being contracted and is unfolded in the operation process; the size problem of instruments in the process of entering the nasopharyngeal cavity is effectively solved; the adenoid excision instrument can be unfolded in the operation process; then adenoid excision is carried out after a Eustachian tube round pillow is protected; fine adjustment can be carried out on adenoid in the excision process; damage to surrounding tissue is prevented, meanwhile; the image of the excision part can be seen in real time in the excision process; excision is more accurate; and the operation efficiency is improved. According to the technical scheme, the adenoid body eliminating device comprises an adenoid body eliminating plate, the eliminating plate is arranged in a protective shell, the protective shell is driven by a driving connecting device, and meanwhile the protective shell is adjusted through a posture adjusting device. And a surgical instrument can extend into a nasopharyngeal cavity in a space as small as possible in a surgical process.

Description

technical field [0001] The invention relates to a medical device, in particular to a minimally invasive adenoid elimination device. Background technique [0002] Adenoids, also called pharyngeal tonsils, are located at the top of the nasopharynx and the posterior wall of the pharynx. Adenoids, like tonsils, grow gradually with age after birth, proliferate vigorously at the age of 2-6, reach the maximum at the age of 8, and gradually shrink after the age of 11. Adult adenoids basically shrink. No trace. [0003] What are the dangers of adenoid hypertrophy [0004] Adenoids are an important part of the pharyngeal lymphatic ring. Under normal physiological conditions, they are the largest at the age of 6 to 7, and gradually shrink after puberty. However, under certain incentives, such as repeated stimulation of adenoids, nasopharynx and adjacent parts of inflammation, adenoids can still hyperplasia and hypertrophy, which will block the choana and block the eustachian tube, r...

AI Technical Summary

Problems solved by technology

[0014] However, it is impossible to fine-tune the ablation site accurately during the ablation process, and at the same time, the volume is limited in the process of extending into the patient's nasopharyngeal cavity, and real-time fine-tuning is often required during the operation to achieve the goal of completely eliminating adenoids , to prevent recurrence, and in the process of adjusting the angle, it is necessary to adjust the part to be eliminated first, and then fine-tune the position of the ablation electrode needle to achieve the purpose of reducing accidental injury
