Problems solved by technology

The anal canal of a person is generally about 4 cm long, but due to individual differences in patients, the anal canal length of each person is not exactly the same. The anal canal of a short patient is generally about 3 to 4 cm, while the anal canal of a tall patient is usually 4 to 6 cm. Because the length of the common anoscope tube is fixed, it is difficult to adapt to these individual differences. Sometimes the anal canal sphincter cannot be fully opened, and sometimes it is inserted too deep beyond the length of the anal canal sphincter. These allow the surgeon to observe the deep tissue of the anal canal The structure poses difficulties, which is not conducive to the smooth operation of the operation

Embodiment 1

[0017] Such as figure 1 As shown, the present invention provides an anoscope, comprising a mirror tube 7, a mirror edge 6 and an inner core 2, the inner core 2 is inserted from one end of the mirror tube 7 and exposed at the other end, and the leaked end is spherical At the end, the outer wall of the mirror tube 7 is provided with a scale line indicating the length, and the outside of the mirror tube 7 is sleeved with a mirror edge 6. When in the inserted state, the left side of the mirror edge 6 is fixed by the fixing rubber sleeve 5.

[0018] The beneficial effects of the present invention are: provide an anoscope, including a mirror tube, a mirror edge and an inner core, the inner core is inserted from one end of the mirror tube and exposed at the other end, and the leaked end is a spherical end, so The outer wall of the mirror tube is provided with a scale line indicating the length, and the outside of the mirror tube is sleeved with a mirror edge. When in the inserted sta...

Embodiment 2

[0020] This embodiment is improved on the basis of Embodiment 1. Except for the following content, others are the same as Embodiment 1. The spherical end of the inner core 2 is provided with a discharge hole 1, and the inside of the inner core 2 is provided with a lubricating fluid. One end of the injection pipeline 4 communicates with the discharge hole at the spherical end, and the other end is threaded with the air bag 3 .

[0021] It should be noted that at present, because the inside of the anus is not smooth enough, when the mirror tube is inserted into the inside, it may be too dry and the friction force is too large, causing damage to the inside of the anus. Therefore, a structure that can inject lubricating fluid into the inside is provided. , can avoid the above defects.

Embodiment 3

[0023] This embodiment is improved on the basis of embodiment 1, except for the following content, others are the same as embodiment 1,

[0024] Wherein, the outer wall of the inner core 2 is provided with a protrusion, and the inner wall of the mirror tube is provided with a groove that cooperates with the protrusion.

[0025] The arrangement of the above-mentioned structure can make the inner core and the mirror tube more tightly combined, and the movement of the inner core can accurately drive the mirror tube to move, and the control is more precise.

Abstract

The invention discloses an anus speculum which comprises a mirror tube, a mirror edge and an inner core, wherein the inner core is inserted from one end of the mirror tube and exposed out of the other end of the mirror tube; the exposed end is a spherical end; scale lines which represent the length are set on the outer wall of the mirror tube; the mirror edge is connected to the exterior of the mirror tube in a sleeving manner; under an inserted state, the left side of the mirror edge is fixed by a fixing rubber sleeve. By the arrangement of the scale lines on the outer wall of the mirror tube, the mirror tube can be actually greater in the length, so that the inner core can be inserted into the mirror tube according to the scales of the scale lines; therefore, the defect that the length of the mirror tube is fixed in the prior art can be overcome; furthermore, by the arrangement of the mirror edge and the fixing rubber sleeve, the mirror tube can be fixed, and the mirror edge can be prevented from falling off.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an anoscope. Background technique [0002] At present, 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 cylindrical and has a protrusion on the head. The outer diameter of the inner core is slightly smaller than the mirror tube Therefore, the inner core can just fit into the mirror tube, and the raised part at the front end of the inner core just sticks out of the mirror tube. In anorectal surgery, the operator inserts an anoscope with an inner core into the anus, and then fixes the mirror tube by suturing the edge of the mirror to the perianal skin, so that the mirror tube can stretch the anal sphincter that makes up the anal canal, At this time, the inner core is pulled out, and the tissue condition in the deep anal...
