Description

technical field [0001] The invention relates to a rectoscope with a light source and a camera, belonging to the technical field of anorectal surgical instruments. Background technique [0002] At present, the closed rectoscope and anoscope can only be used for inspection, and cannot perform surgical operations through the anus. The rectal retractor can only assist low rectal surgery. The operation of surgical instruments through the anus and the proctoscope port affects the surgical field of view. The surgical field of view is small and difficult to operate. Moreover, it is not suitable for high rectal lesion surgery; rectal surgery requires laparotomy, which not only causes postoperative pain, but also brings great trouble to postoperative recovery. Contents of the invention [0003] The object of the present invention is to provide a proctoscope with a light source and a camera, which can directly operate through the anus according to the rectal lesion position, has a la...
