A further preferred scheme, the anus segment is also provided with a detachable operation support table, and there are 3-6 open operation channels with a diameter of 3-12mm on the support table;

The use process is as follows: before the operation, remove the operating support table, put the inner core into the anoscope body and extend it into the patient's anus, so as to facilitate the entire anoscope body to be pushed into the patient's anorectum, and observe the anoscope body entering the patient's body through the observation mirror. When it is in place, take out the inner core, which can not only relieve the discomfort of the patient, but also ensure that the internal environment of the anoscope is good, and foreign objects in the intestine will not enter it; at this time, install the operating support table back into the support ring, according to The size of the lesion body to be resected can be controlled by rotating the control knob. If the lesion body is small, the expansion segment should be properly closed. If the lesion body is large, the expansion segment will be opened to complete the excision of the lesion body. After excision, the extension is closed, the anoscope is removed, and the operation is completed.

The beneficial effects of the present invention: compared with the prior art, the anus surgery platform of the present invention is easy to adjust, and the size of the anoscope can be adjusted according to the size of the actual lesion, thereby greatly reducing the difficulty of operation and improving the success rate of the operation. The anus surgery platform of the present invention does not need to be inflated into the intestinal cavity during use, which not only relieves the patient's own pain, but also stabilizes the surgeon's surgical field and further improves the success rate of surgery. Finally, the anus surgery platform of the present invention is suitable for different patients to perform minimally invasive procedures Surgery, without open surgery or laparoscopic surgery, reduces the patient's own physical trauma, worthy of clinical promotion.

Detailed ways

Example 1

As shown in Figures 1 and 5, an adjustable anus surgery platform includes an anoscope body and an inner core 12. The inner core 12 is placed in the mirror body to facilitate pushing into the patient's body. The inner core 12 is a transparent inner core. 12 is provided with a hollow channel in the middle, and the hollow channel is used to place the observation mirror; the mirror body includes the front section 1, the expansion section 2, and the anus section 3 that are set sequentially from front to back; the anus section 3 tail end is provided with a control knob 4; The control knob 4 is set at the tail end. According to the different positions of the lesion body in different patients, the expansion section 2 of different specifications is selected. The expansion section is 5-20 cm long, and the diameter of the expansion section 2 can be changed. The expansion section 2 includes a blade 5 and a control rod 6. Control One end of the rod 6 is connected to the blade 5, and the other end is connected to the control knob 4. The rotation of the control knob 4 drives the blade 5 to open and close, so as to realize the change of the diameter of the expansion section 2. Select the anoscope body of the U-shaped groove 7 with different opening sizes, and control the opening and closing angle with the U-shaped groove through the blade; the opening of the U-shaped groove 7 is 30-120 degrees, and the opening size of the blade and the U-shaped groove is 20-220 degrees; the anus segment 3 includes a support ring 9, a fixed piece 10 and a holding piece 11; the front end of the support ring 9 is connected to the expansion section 2, and the rear end is provided with at least two fixed pieces 10 and a piece of holding piece 11 along the circumference, One end of the fixing piece 10 is connected to the support ring 9, and the other end is opened to the outside of the ring.
