Abstract

The utility model provides a cage-type speculum for a rectum and an anal tube, which adapts to the treatment of diseases of the rectum and the anal tube. The speculum is formed by the method that four fixed steel needles and twelve movable steel needles which are connected with a semi-spherical head and a ring-shaped tail part. The tail parts of the twelve movable steel needles bend into a ring shape towards one side When the utility model is used, all the parts of the rectum wall can be observed through a perspective cage-type perisporium, and the diseased parts can be intruded into the speculum by means of pumping and pulling movable steel needles. The elliptical head part of the speculum and the cylindrical body part determine that the speculum is easy to fix and not easy to slide out.

Description

Cage rectum anal tube specula

The specula that this utility model uses when relating to a kind of diagnosis and treatment rectum, anal canal disease.

Traditional anal canal, rectal speculum are two kinds of cartridge type, crane bill types, because being metal, the perisporium of traditional specula constitutes, can not have an X-rayed, can observe the whole of distal rectal and anal canal so need rotate or pump specula in use, and because the tension force effect of anus muscle, the specula majority all can skid off voluntarily, thereby needs that assistants help to control, fixing specula during diagnosis and treatment more, makes troubles to practical operation.

The purpose of this utility model aims to provide a kind of new cage rectum anal tube specula, and it can provide the complete broad visual field, a good operation to appear to clinician, and can prevent effectively that specula from skidding off voluntarily.

The purpose of this utility model is to realize like this, the cage specula is made of the afterbody that the fixed draw point of 12 active draw points and 4 connects a hemispheric head and a cast, and 4 fixed draw points are unified into the steel ring of hemispheric head and afterbody the main body of specula.12 active draw points constitute the perisporium of specula, and can extract out smoothly and insert, and its afterbody bends towards a side and becomes round, can conveniently control draw point and insert and extract out.

Advantage of the present utility model and effect are that diagnosis and treatment person need not rotate and pump specula, the cage type perine that can see through specula is intactly observed the whole of rectum and anal canal, and in case find pathological changes, can be by adjacent several of 12 movable draw points of pull, lesion portion is charged in the specula, be beneficial to diagnosis and treatment person pathological changes is imposed treatment.In addition, profile of the present utility model is the column of head like ellipse, so after inserting anal canal, can not deviate from voluntarily because of the tension force of muscle, a people can independently finish diagnosis and treatment.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1, be profile according to the cage rectum anal tube specula that the utility model proposes.

Fig. 2,3, the 4th, the plan view of afterbody steel ring and profile.

Fig. 5,6, be the profile and the plan view of head.

Describe details and working condition in detail in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

This specula comprises that the ring for fixing (2) of a hemispheric head (1), afterbody, 4 fixing heads and the draw point (3) of afterbody, 12 mobilizable tail ends become the draw point (4) of round to a lateral bending.4 fixed draw points (3) are concordant with the steel ring (2) of afterbody.

During diagnosis and treatment specula is inserted anal canal, by extraneous light, intestinal wall is observed in the slit that can see through draw point, and can diseased region be charged in the specula by the adjacent draw point of pull (4) when finding pathological changes, can implement to treat.

Claims

A kind of cage rectum anal tube specula that uses during 1, as rectum and anal canal disease treatment, this specula is characterised in that: by 4 fixedly draw point (3) and 12 active afterbodys steel ring from afterbody a to lateral bending that become the draw point (4) of round to connect hemispherical nose and form the perisporium of having an X-rayed of specula.
2, according to claim 1, described cage rectum anal tube specula, it is characterized in that: 12 movable draw points (4) can be along sliding extraction and insertion, and when adjacent draw point is divided in the withdrawing part, can make diseased region charge into specula.
3, according to claim 1,2, described cage rectum anal tube specula, it is characterized in that: the afterbody of 12 movable draw points (4) is beneficial to diagnosis and treatment person draw point is inserted and extracts out to a routine crooked lopping.
