It relates to an anal surgical device.

In general, in the case of a conventional open surgery for treating a patient, a large incision site and a large amount of bleeding generated during surgery are slow to recover the patient after surgery, and a large scar remains after the operation, which affects a patient's later life. Recently, new surgical techniques such as Minimal Invasive Surgery (MIS) and Natural Orifice Transluminal Endoscopic Surgery (NOTES) have been developed to overcome the shortcomings of such open incision surgery.

Minimally Invasive Surgery is a surgical technique that involves cutting only the smallest part of the patient's body using an elongated surgical tool specially designed to minimize the incision needed for surgery. Surgical procedure that inserts surgical instruments through natural holes (esophagus, anus, vagina, etc.) in human body to transfer surgical instruments to the procedure site without incision of patient's body to transfer surgical instruments Technique. Since minimal minimally invasive surgery and scarless surgery require fewer incisions and significantly less bleeding compared to laparotomy, the patient's recovery period is fast after surgery and the scars that appear externally are small. The number of procedures is increasing significantly.

As an example of the scarless surgical technique described above, a surgical device for transanal endoscopic microsurgery (TEM) is used.
