Slippery object extractor used in otolaryngology department

Abstract

The invention belongs to the technical field of medical apparatuses and instruments used in the otolaryngology department and particularly relates to a slippery object extractor used in the otolaryngology department. The slippery object extractor comprises a transparent cylinder and an elastic wire, wherein the transparent cylinder is in a shape of a transparent hollow tube, the elastic wire is made of a transparent material, the end, close to the elastic wire, of the transparent cylinder is provided with a hinge flare angle control tube, the end, away from the elastic wire, of the transparentcylinder is rotatably connected with a flare angle adjusting barrel. The front end of the transparent cylinder is provided with a flare angle control tube controlled through a flare angle control sleeve. When the slippery object extractor is used, the angle of the flare angle control tube can be changed by turning the flare angle adjusting barrel, flare angle change of the elastic wire can be achieved, the length of the elastic wire is changed through cooperation with a tightness adjusting nut, and certain support is provided through the flare angle control tube, so that the extractor is easyto control, the foreign matter taking reliability is improved, light for a treatment point is easy to supplement, outside light adjustment is not needed, and the treatment convenience and treatment accuracy are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments for ENT, and in particular relates to a slippery object remover for ENT. Background technique [0002] A common patient in otolaryngology is that there are foreign objects in the organs, and they cannot remove them by themselves. They can only go to the hospital to use a professional extractor to remove the foreign objects. Clinically, it is a common emergency case that foreign objects enter the nasal cavity and cause nasal cavity blockage. , usually with a cerumen hook to remove the foreign body. [0003] The cerumen hook is easy to cause damage to the nasal cavity wall, and the efficiency is low. For this reason, the invention patent application number CN201220588062.5 proposes a nasal cavity foreign body extractor, which includes a hollow handle bar. It is characterized in that: the front end of the handle bar is set There is a soft rubber head, the rear end is provided with a thre...

[0003] The cerumen hook is easy to cause damage to the nasal cavity wall, and the efficiency is low. For this reason, the invention patent of application number CN201220588062.5 proposes a nasal cavity foreign body extractor, which includes a hollow handle bar. It is characterized in that: the front end of the handle bar is set There is a soft rubber head, the rear end is provided with a threaded column that partially extends into the handle, and the threaded column is provided with a threaded adjustment sleeve; an elastic wire is placed in a U shape, and the two ends pass through the soft rubber head and enter the handle Inside, and both ends are fixedly connected to the lower end of the threaded column, but the scheme has the following problems:

[0004] 1. The opening angle of the elastic wire is not easy to control, and there is no support for the contact part with the handle, so it is not easy to accurately control when taking out the operation, which increases the working time and even increases the risk of treatment;

[0005] 2. An external lighting source is required to supplement the light. Not only the light irradiation point needs to be adjusted, but also the lighting during operation cannot be guaranteed, which brings great inconvenience to the patient's foreign body removal operation.
