Special cutter head for departments of otolaryngology and preparation method thereof

Abstract

The invention discloses a special cutter head for departments of otolaryngology and a preparation method thereof. The cutter head includes a sphere (1) and a shaft body (2) in mutual connection; the axis of the shaft body (2) passes through the center of the sphere (1); the outer wall of the sphere (1) is provided with multiple opening slots (3), and multiple circumferential flow channels (4) are arranged at the bottom of each of the opening slots (3); the multiple circumferential flow channels (4) in the respective opening slots (3) are in mutually parallel arrangement, and a main flow channel (5) is arranged on the sphere (1) and the shaft body (2); one ends of the circumferential flow channels (4) communicate with the main flow channel (5), and the other ends of the circumferential flow channels penetrate the outer wall of the sphere (1); the circumferential flow channels (4) and the main flow channel (5) are in inclined arrangement; and the openings of the opening slots (3) are provided with blades (6). Therefore, the special cutter head for departments of otolaryngology capable of rapidly and effectively excise and discharge foreign matters and a preparation method thereof are provided.

Description

technical field [0001] The invention relates to the field of otolaryngology, in particular to a special cutter head for otolaryngology and a preparation method thereof. Background technique [0002] When there are foreign bodies attached to the inner walls of narrow passages such as the nasal cavity, ear canal, and throat, doctors usually need to use special instruments to clean them up; the common method in the prior art is to use scissors or a cutting tool with a blade to remove foreign bodies from the passages. The inner wall is detached, and then the sheared foreign matter is removed from the channel with a clamping tool such as tweezers. However, using these tools and methods to clean foreign bodies in the nasal cavity, ear canal, throat and other passages is easy to cause the foreign bodies to fall away from the inner wall of the passage for the first time and fall to a deeper position, which affects the effect of cleaning. Specifically, when the foreign body in the t...

Problems solved by technology

However, using these tools and methods to clean foreign bodies in the nasal cavity, ear canal, throat and other passages can easily cause foreign bodies to fall away from the inner wall of the passage for the first time and fall to a deeper position, affecting the cleaning effect

Specifically, when the foreign body in the throat is cut by the cutting tool, it is not removed by the clamping tool in time and falls to a deeper position in the throat; or in other words, the foreign body in the ear canal is not clamped in time after being cut The tool is removed and dropped to a deeper position, it is more difficult to remove

Generally speaking, there is a problem that the cleaning tools and methods of otolaryngology in the prior art are not timely and effective in cleaning foreign bodies, and the cut foreign bodies cannot be quickly and effectively discharged
