Description

Anus speculum and using method thereof

Technical Field

The invention relates to the technical field of medical instruments, in particular to an anoscope and a using method thereof.

Background

At present, the known anoscope structure mainly comprises an endoscope tube and an inner core, wherein the cylindrical head of the inner core is provided with a bulge, the outer diameter of the inner core is (slightly) smaller than the inner diameter of the endoscope tube, so that the inner core can be just sleeved into the endoscope tube, and the bulge part at the front end of the inner core just extends out of the endoscope tube. In the operation of anorectal surgery, the operator uses the anoscope that will overlap there is the inner core to insert the anus, and is fixed with the mirror tube on the skin of anus through sewing up the mirror edge afterwards, mirror tube alright with prop open the anal canal sphincter that constitutes the anal canal, pull out the inner core this moment, see through mirror tube alright with seeing the tissue condition of anal canal depths, make things convenient for in the operation. The length of the anal canal of a person is about 4 cm generally, but the length of the anal canal of each person is not completely the same due to individual difference of patients, the length of the anal canal of a patient with short stature is about 3-4 cm generally, and the length of the anal canal of a patient with high stature is 4-6 cm generally.

If the authorization notice number CN106256311B discloses an anoscope, the structure is simple, the use is convenient, and the observation tube matched with the lens cone is used, and the illuminating optical fiber is embedded on the inner wall of the observation tube, so that enough illumination can be conveniently provided for a doctor to observe the focus of a patient. However, this solution also has the following problems: when the endoscope core is inserted into the anus, the anus is not smooth enough, and the endoscope tube is inserted into the anus, so that the anus is possibly damaged due to too dry and too large friction force.

When the anus speculum is inserted, the anus speculum is inserted according to the scales of the scale marks, the defect that the length of the speculum tube is fixed in the prior art can be overcome, and in addition, the speculum edge and the fixed rubber sleeve are arranged, so that the speculum tube can be fixed and the speculum edge can be prevented from falling off. Although the scheme considers that the inside of the anus is not smooth enough and the insertion may cause damage in the anus, the lubricating liquid is discharged from the discharge hole at the top of the inner core, and under the condition that the lubricating liquid is added through the discharge hole, a large part of the lubricating liquid enters the anus and flows into the tail end of the rectum, so that the lubricating effect is small, the observation is influenced, the condition that the outflow of the lubricating liquid causes pollution is not considered, and the lubricating liquid flowing out in the operation is not cleaned in time.
