Rotating mechanism and medical paranasal sinus suction cutter

Abstract

The invention discloses a rotating mechanism and a medical paranasal sinus suction cutter. The base body is installed at the upper end of a table top, wherein a bevel gear A for adjustment is rotatably installed on the inner surface of the base body, a fixing shaft for rotation positioning is fixedly installed at the lower end of the inner surface of the base body, a bevel gear B meshed with the bevel gear A is fixedly installed at the upper end of the outer surface of the base body, and a bevel gear C is mounted on the outer surface of the bevel gear B. According to the rotating mechanism and the medical paranasal sinus suction cutter, the base body with the adjusting rotation function is arranged, and the rotating mechanism rotates through the bevel gear A installed in the base body; the angle of the middle rod is adjusted through meshing rotation, so that cutting use at different angles is met; by installing a positioning block, the stability of the device is improved, and falling off and breakage are prevented; besides, through cooperative use of the installed connecting block and the adjusting block, the angle of the cutting supporting rod can be effectively adjusted.

Description

Technical field [0001] The present invention relates to the field of medical technology, in particular a rotating mechanism and a medical sinus adduct cutter. Background technique [0002] When the sinus surgery, the lesion is required to remove the lesion using a cutting device, and the sinus adduct cutter is required to operate, but the existing cutter still has certain defects, such as: [0003] The authorization notice number is CN202426643U, the authorized announcement date 20120912 "Soul sinus cutting tool with electric knife function", a sinus cutting tool head with electric knife function, including knife, cutting tube and electric head, ...; The new type provides a sinus cutting tool that can be cut while cutting the side electric knife while performing sinus surgery, so that the surgical bleeding is less, safe, and effectively saves the sinus cutting cutter head of the electric knife function of the surgical time; [0004] However, the above prior art solution has the f...
