The working principle is as follows: the scraper 6 is inserted into an operation incision of the chest of a patient, the rotary sleeve 1 is rotated and the driving rod 2 is kept still, the thin layer 62 on the scraper 6 scrapes the necrotic part in the chest of the patient, due to the relative rotation between the rotary sleeve 1 and the driving rod 2, the helical blade 21 on the driving rod 2 enables the interior of the rotary sleeve 1 to form a negative pressure state, and the rotary sleeve 1 absorbs pus through the hollow circular plate 3, the hollow rod 4 and the absorption hole I51 on the hollow sphere 5; meanwhile, as the scraper 6 rotates, under the action of centrifugal force, the counterweight solid ball 8 in the attached drawing 4 rises, partial air pressure at the bottom of the first elastic sheet 9 pulls the first elastic sheet 9 downwards, air pressure at the top of the first elastic sheet 9 pushes the first elastic sheet 9 downwards, thereby leading the first elastic sheet 9, the connecting rod 10 and the cutter 11 to descend, the cutter 11 is separated from the thin layer 62 on the scraper 6, and because the distance between the two walls attached to the counterweight solid balls 8 is greater than the distance between the two walls attached to the elastic sheet one 9, therefore, one part of gas pushed by the counterweight solid ball 8 pushes the first elastic sheet 9 to move, the other part of gas enters the connecting rod 10 through the vent hole 101 and then enters the cutter 11 through the connecting rod 10, the air pressure inside the cutter 11 is increased, the second elastic sheet 1111 deforms and pushes the transmission rod 12 to move, and the transmission rod 12 drives the cutting wheel 13 to rotate for a certain angle.

After the scraper 6 finishes scraping, the rotating sleeve 1 stops rotating, the driving rod 2 is rotated, so that the driving rod 2 and the rotating sleeve 1 are still in a relative rotating state to maintain a negative pressure state in the rotating sleeve 1, the centrifugal force applied to the counterweight solid ball 8 disappears due to the fact that the scraper 6 stops rotating, the first elastic sheet 9 in the attached drawing 4 rises and resets, the counterweight solid ball 8 descends and resets, so that the first elastic sheet 9 drives the connecting rod 10 and the cutter 11 to descend, under the action of the air pressure in the cutter 11 and the connecting rod 10, the air resets to the inside of the cavity 631 through the cutter 11, the connecting rod 10 and the vent hole 101, the second elastic sheet 1111 automatically resets and pulls the driving rod 12 to move, the driving rod 12 pulls the cutting wheel 13 to rotate again, and the rotating directions of every two adjacent cutting wheels 13 are opposite, the fan-shaped grooves 131 in the cutting wheel 13 cut off necrotic body tissues adhered to and wound on the thin layer, and the cut necrotic body tissue enters the hollow circular plate 3 and the inside of the rotating sleeve 1 through the second absorption hole 64, preventing the necrotic body tissue adhered and entangled to the spatula 6 during the process of removing the spatula 6 from pulling out healthy body tissue.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
