Abstract
The utility model discloses an anorectal dilator which can improve the operating efficiency and reduce pains of a patient. The technical scheme adopted by the utility model is that the anorectal dilator comprises a leading-in part (1) and an extension part (2) which form an integral structure, and is characterized in that an interlayer (3) and a baffle plate (4) are arranged inside the leading-in part (1); and the interlayer (3) is connected with the leading-in part (1) through a fixing point (5).
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of anorectal dilator that can improve operation efficient, reduce the patient suffering.
Background technology
STARR (Stapled Transanal Rectal Resection) operation is the new art formula that is used to treat encysted rectum that Italian scholar A.Longo proposes; This art formula adopts two PPH anastomats; Excise lower end antetheca in the rectum respectively and rear wall is tediously long, the mucosa and the Submucosa of prolapsus, the width and the degree of depth of having dwindled encysted rectum, anastomotic stoma make Submucosa and flesh layer cicatricial adhesion; Strengthened the strength of rectum front wall; Alleviated the degree of encysted rectum, thus the capsule bag shaped structure that forms when eliminating rectum lower end defecation, the internal rectum anatomical structure of lower end in the reconstruct rectum; Reach the dynamic function that recovers normal anatomical structures, can improve the various symptoms of encysted rectum.This art formula also can solve prolapsus in the rectal mucosa, internal hemorrhoid and mixed hemorrhoid simultaneously, thereby also can eliminate the clinical symptoms that above-mentioned disease causes, and improves curative effect, and clinical practice is extensive.
At present; People carry out STARR when operation usually by the anorectal dilator to enlarge surgical field of view; Prevent the operation of anus effect of contraction; Need before block non-operation side earlier at the anastomat excision mucosa of screwing with abdominal spatula, injury-free with the protection mucosa, be close to the rectal wall insertion and abdominal spatula is many along the dilator outside.Abdominal spatula is wooden, wastes time and energy during insertion, and damages mucous membrane of rectum easily, has brought a lot of unnecessary troubles to medical personnel, has prolonged operating time, has also brought very big misery to the patient simultaneously.
The utility model content
The purpose of this utility model is to overcome the shortcoming in the above-mentioned technology; Provide a kind of and in the anorectal dilator, be provided with interlayer, place plastics system baffle plate through interlayer, baffle edge is mellow and full smooth; Save trouble during placement and laborsaving; And do not damage mucosa, improved operation efficient, reduced patient suffering's anorectal dilator.
This utility model is to realize above-mentioned purpose like this:
A kind of anorectal dilator comprises lead-in portion (1) and epitaxial part (2) with integrative-structure, it is characterized in that: be provided with interlayer (3) and baffle plate (4) in the described lead-in portion (1).
Epitaxial part (2) is provided with 4 oval slotted holes (7), and said oval slotted hole is symmetrically distributed.
Three fixing points (5) linked to each other with lead-in portion (1) around interlayer (3) passed through.
Said baffle plate (4) is an arcuate structure, and plastic has external ear (6).
Said interlayer (3) and baffle plate (4) symmetric design.
In the operation process, put into Improvement type anorectal dilator, its lead-in portion (1) can fully be expanded anal canal, and open surgical field of view is through 4 oval slotted holes (7) the suture fixed expander on the epitaxial part (2), with anti-skidding.Before the anastomat excision mucosa of screwing, put into baffle plate (4) to protect non-field of operation mucosa through interlayer (3), save trouble and laborsaving, and do not damage mucosa around the rectum.
This utility model is simple and reasonable for structure, when lead-in portion inserts anus, can fully expand anal canal, open surgical field of view; In the STARR operation, place plastics system baffle plate, save trouble and laborsaving, and do not damage mucosa through interlayer; Improved operation efficient, reduced the patient suffering, be worthy of popularization.
Below in conjunction with accompanying drawing and embodiment this utility model is done further explanation.

The specific embodiment
Embodiment of accompanying drawings.Fig. 1, Fig. 2 are Improvement type anorectal dilator front elevation and side view; This Improvement type anorectal dilator comprises the lead-in portion 1 and epitaxial part 2 with integrative-structure; Be provided with interlayer 3 and baffle plate 4 in the described lead-in portion 1; Interlayer 3 links to each other with lead-in portion 1 through three fixing points 5, and epitaxial part 2 is provided with 4 oval slotted holes 7, and oval slotted hole is symmetrically distributed.Baffle plate 4 is an arcuate structure, and plastic has external ear 6, interlayer 3 and baffle plate 4 symmetric designs.(referring to Fig. 3, Fig. 4).
In the operation process; Put into Improvement type anorectal dilator; Its lead-in portion 1 can fully be expanded anal canal, and open surgical field of view is through 4 on the epitaxial part 2 oval slotted hole 7 suture fixed expanders; Before the anastomat excision mucosa of screwing, put into baffle plate 4 through interlayer 3 and can protect non-field of operation mucosa injury-free.
