Abstract
The utility model relates to a non-traumatic negative-pressure anal tube dilator which uses negative pressure to fix and expand an anal tube and comprises an inner core of the anal tube dilator, a negative-pressure groove on a main body of the anal tube dilator, and a negative-pressure switch. The inner core is inserted in the main body and then is inserted in an anorectum to be tightly attached to anal skin before being connected with the negative pressure for absorbing gas in the negative-pressure groove, and the anal tube dilator can be automatically and tightly fixed on the anorectum in a negative-pressure state. After the anal tube dilator is used, the switch is switched on and the anal tube dilator taken out after the negative pressure is eliminated.
Description
Technical field
This use is novel to relate to a kind of anal canal dilator when treating hemorrhoid, rectal mucosa prolapsus in clinical medicine, cooperates PPH ring cutting apparatus to manipulate.
Background technology
1975, Thomson has proposed " anus pad " theory, has promoted people to the re-recognizing of hemorrhoid, and has also driven the change of the Therapeutic Method of hemorrhoid, protects the anus cushion function to build consensus as far as possible.In numerous methods of treatment hemorrhoid, the PPH tool revolutionary character of performing the operation.
The present defective that exists of the anal canal dilator of wide clinical application PPH anastomat: fixed anal canal dilator need sew on and close fixingly in the operation, and human body is had wound.
Summary of the invention
At defective to the dilator of use in the current PPH apparatus operation, this utility model provides a kind of noinvasive anal canal negative pressure dilator, this noinvasive anal canal negative pressure dilator not only can be expanded anal canal, and utilizes vacuum suction to replace suture needle to fix, and possesses AT advantage.
The technical scheme that its technical problem that solves this utility model adopts is: in subsides anorectal region, subsides anal skin lateral layout negative pressure groove and the individual event negative pressure switch of expander body and chimb formation central area negative pressure grooved area far away at the lateral surface of dilator main part, that the near-end design is slick and sly.The cone shape that dilator inner core insertion end is designed to slickness can insert new cone of formation in the expander body closely, 50 milliliters syringe cylinder or electric suction apparatus gas bleeding in the individual event negative pressure switch connection clinical medicine, the anal canal dilator is fixed on anorectal region, the perianal closely under negative pressure, reaches to replace the fixedly effect on the anal skin of present anal canal expansion purpose and suture needle.
The beneficial effects of the utility model are, have avoided the suture needle of use skin to fix, and remedy the skin trauma suture needle that the anesthesia of proctodeum enlargement of pipe device takes down and fix, and anesthesia back patient's anal skin is because of the defective of suture needle damage pain.

The specific embodiment
During use noinvasive anal canal negative pressure dilator inner core (5) is inserted the noinvasive anal canal negative pressure expander body outside, the inner (2).Be coated with lubricating oil on noinvasive anal canal negative pressure dilator inner core and body, after anal canal suitably expanded anus, suitable physiology direction was suitably firmly expanded anal canal and is inserted in the anal canal, makes noinvasive anal canal negative pressure dilator negative pressure trough outer end (1) be adjacent to anal skin.Connect negative pressure switch (4) with medical suction depressor tool, gas (3) in the sucking-off noinvasive anal canal negative pressure dilator negative pressure trough.Under negative pressure state, make noinvasive anal canal negative pressure dilator being fixed on the anorectal region tightly.Finish using, handle (7) is opened switch (6), eliminates negative pressure, and noinvasive anal canal negative pressure dilator can break away from human body and take out.
Claims (4)
1, a kind of noinvasive anal canal negative pressure dilator, form by negative pressure grooved area and negative pressure switch on anal canal dilator inner core and the anal canal dilator, it is characterized in that: form new cone after anal canal dilator inner core and the socket of anal canal dilator main part and insert in the anorectal region by the head end order.
2, according to right 1 described noinvasive anal canal negative pressure dilator, it is characterized in that: the lateral surface design chimb that negative pressure is far away, near-end is slick and sly at the dilator main part forms the negative pressure grooved area.
3, according to right 1 described noinvasive anal canal negative pressure dilator, it is characterized in that: design unidirectional negative pressure switch in the noinvasive anal canal negative pressure dilator negative pressure grooved area outside is extracted grooved area gas out.
4, according to right 1 described noinvasive anal canal negative pressure dilator, it is characterized in that: the anal canal dilator inner core insertion end of noinvasive anal canal negative pressure dilator is designed to the cone shape of slickness.
