Novel two-blade anus expander for NOSES operation

Technical Field

The utility model belongs to the technical field of medical equipment, concretely relates to a novel two-leaf anus expander for NOSES operation.

Background

With the development of surgical technology and the progress of minimally invasive concept, colorectal tumor sampling surgery (NOSES) through natural orifice develops rapidly in China. NOSES refers to abdominal wall non-auxiliary incision operation which uses laparoscope and other instruments to complete various conventional operation operations (excision and reconstruction) in abdominal and pelvic cavities and takes specimens through natural cavities (rectum, vagina or oral cavity) of a human body, wherein the anus is the most common specimen taking way for colorectal NOSES application, and the full anus expansion is required before specimen taking.

It is common practice for a doctor to insert a finger into the anus of a patient and then force the two hands to spread outward. Due to the control of strength and the individual constitution of the patient, anal sphincter muscle of the patient is often damaged by the instantaneous excessive strength, and anal fissure is caused. Meanwhile, as the anus dilatation needs to be continued for a long time, the hands of the doctor can feel sore quickly, which has certain influence on the operation process, the patient and the health of the doctor.

In view of the above, some proposals have been made in the prior art, such as a two-blade anus dilator disclosed in chinese patent application No. 89206428.5, in which a two-blade forceps with a detent is designed to replace manual anus dilator operation. However, in the structure, the anus expanding part adopts the straight plate-shaped blade, and the contact between the structure and the anus in actual use can be concentrated on the upper end and the lower end of the blade, so that the stress of the local part of the anus is more concentrated, and the risk of anal fissure is increased.
