Problems solved by technology
Ordinary anoscope is difficult to adapt to these individual differences due to the fixed length of the mirror tube. Sometimes the anal sphincter cannot be fully opened to expose the lesion, and sometimes it is inserted too deep beyond the length of the anal sphincter and the lower edge of the tumor. Exposing the anorectal tissue structure makes it difficult to observe the tumor and the surgical field, which is not conducive to the smooth operation

The invention discloses a telescopic anoscope. The telescopic anoscope is characterized by comprising an anoscope tube and an anoscope core, wherein the anoscope tube comprises an outer anoscope tubebody and an inner anoscope tube body, an anoscope tube flange is integrally arranged at one end of the outer anoscope tube body and comprises an arc-shaped flange and a sliding flange, the arc-shapedflange and the sliding flange are folded into the outer anoscope tube body, outer anoscope threads are arranged on the outer anoscope tube body, the endoscope tube body comprises an insertion end inserted into the sliding flange and an external connection end capable of being connected with the outer endoscope tube in a threaded mode, the external connection end is provided with endoscope threadsmatched with the outer endoscope threads, and in the process that the endoscope tube is screwed into the outer endoscope tube, when the endoscope threads abut against the arc flange, the maximum screwing-in stroke of the endoscope tube is achieved. The length of the anoscope tube can be conveniently adjusted in the rotating process of the endoscope tube in the outer endoscope tube body through theendoscope thread and the outer endoscope thread which are in threaded connection, so that the length of the anoscope tube is matched with the length of an anal tube of a patient and the position of atumor, the tissue condition of the near end of the anorectum can be seen clearly, the tumor operation field is better reserved, and smooth operation is facilitated.
Description
technical field [0001] The invention relates to a device capable of stretching the anal sphincter in anorectal surgery, more specifically, it relates to a retractable anoscope. Background technique [0002] At present, the clinical treatment of rectal and anal cancer with tumors located within 5cm from the anus is relatively difficult. When performing anus-preserving surgery, due to poor exposure of the operative field, it is impossible to perform precise operations. anus and affect the patient's quality of life. The known anoscope structure is composed of a mirror edge, a mirror tube and an inner core, the mirror edge and the mirror tube are fixedly connected to form an integrated structure, the inner core is a cylindrical head with a protrusion, and the outer diameter of the inner core is slightly smaller than that of the mirror tube inner diameter, so the inner core can just fit into the mirror tube, and the raised part of the front end of the inner core just sticks out ...
