Abstract

The utility model discloses an anus and rectum endoscope formed with an endoscope coat and a guiding core bar. The endoscope coat is formed with a taper pipe and a handle fixed on the taper pipe. The front end of the guiding core bar is a spherical guiding head of which back end is a taper body. The taper of the taper body matches with the inner diameter of the front end of the endoscope coat and the back end of the taper body is fixed on the middle of the guiding core bar. A button is arranged on the back end of the middle of the guiding core bar. The utility model is easy to be inserted into the anus and rectum, can reduce the examiners' suffering and pain. The endoscope coat is taper shaped and the hole that is on the back of the endoscope coat is big, is convenient for the examinee to observe and treat. The utility model is used only once and can reduce cross-infection.

Description

A kind of Anoscope and proctoscope

This utility model relates to a kind of Anoscope and proctoscope.

Chinese patent " rectal speculum " (patent No. 94203782.0) provides a kind of rectum to detect the specula scheme of using, it is made up of specula main body and guiding mandrel, the specula main body is a hollow pipe, this pipe middle part is straight pipe design, its shortcoming is that pipe diameter like this is too thick, then is difficult for inserting in the anorectal; It is too little to leave the space that medical operator spies on and operate for as detailed rules and regulations too, is difficult for seeing clearly or operating.In addition, with the lug on forefinger and the horn mouth edge, middle finger clamping hollow pipe rear end, operation is convenient inadequately, can influence and observe and operation.

The purpose of this utility model be to improve the shortcoming of prior art and provide a kind of observe clear, easy to operate, hold firm Anoscope and proctoscope.

For achieving the above object, this utility model is taked following design: this Anoscope and proctoscope is dimerous by specula overcoat and guiding core bar, so the specula overcoat is to be made of a conical pipe and a lever fixed thereon, the bus of described conical pipe is a straight line, to constitute the conical pipe of taper mutation not; The bus of described conical pipe is a broken line, to constitute the conical pipe that becomes taper mutation along the conical pipe axis direction.Described taper mutation is that from front to back tapering becomes big; The bus of described conical pipe is a curve also, and constituting the conical pipe that becomes taper mutation along the conical pipe axis direction, described taper mutation is that from front to back tapering becomes big.Described lever is and conical pipe all-in-one-piece plate body; The profile body that has reinforcement that described lever also fuses with conical pipe.The front end of described guiding core bar is the sphere guide head, the rear end of this sphere guide head is a cone, its tapering and specula overcoat conical pipe front inner diameter are complementary, and its cone rear end is fixed with guiding core bar stage casing, and head is pressed in rear end, described guiding core bar stage casing, so that in manipulating, hold the Anoscope and proctoscope lever, thumb is pressed the residence and is stated and press head, and Anoscope and proctoscope is inserted anorectal slowly, and then, carry out anorectal inspection or treatment the taking-up of guiding core bar.Described guiding core bar can design like this, the front end of guiding core bar is the sphere guide head, the rear end of this sphere guide head is the cone that is complementary with specula overcoat conical pipe front inner diameter, it is criss-cross or annular guiding core bar stage casing that its cone rear end is fixed with a section, described guiding core bar rear end is fixed with a disk that has groove and does and press head, pushes away for using middle finger to press.

During this utility model used, the examiner held lever, and thumb is pressed the guiding core bar, this specula is inserted from anus slowly, extract the guiding core bar then, the specula overcoat struts rectum, the examiner just can check pathological change of anorectal from the bigger horn mouth of rear portion conical pipe, and checking finishes extracts the specula overcoat again out.

This utility model front portion is designed to sphere, is easy to insert anorectal, and specula overcoat front portion is less, can reduce feeling bad with painful of examinate; But because of specula overcoat taper mutation, lateral opening thereafter big, be convenient to the examiner and observe and treatment.This product is by the plastic production of nontoxic pair of effect, and disposable use can reduce cross infection.

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment 1

See also Fig. 1, Fig. 2, Fig. 3, this utility model partly is made up of for 2 liang specula overcoat 1 and guiding core bar.Described specula overcoat 1 is made up of a conical pipe 11 and one and its lever that is solidly fixed 12; The bus of described conical pipe is a broken line, and to constitute the conical pipe 11 that becomes taper mutation along the conical pipe axis, described taper mutation is to become big from front end tapering to the back-end.The section bar that the described lever 12 that is solidly fixed with conical pipe 11 is made up of surface plate 121 and reinforcement 122.The front end of described guiding core bar 2 is hollow sphere guide head 21, and the rear end of this sphere guide head is a taper, and its tapering and conical pipe 11 front inner diameter are complementary.One section is that the front end of criss-cross guiding core bar 22 has one to be the plectane 221 of one with it, and its rear end has one to press 222 with it for one.This guiding core bar 22 cements in sphere guide head 21 by the plectane 221 of its front end.

In the use, guiding core bar 2 is packed in the specula overcoat 1, the operator holds lever 12, and thumb presses 222, and this specula is inserted anorectal slowly, extracts the guiding core bar then out, and the operator can check or treat anal and intestinal disease.Treat inspection and finish, extract specula overcoat 1, this Anoscope and proctoscope is collected destroyed.

Embodiment 2

See also shown in Figure 4ly, be disclosed as another kind of specula jacket structure sketch map among the figure, the bus of its conical pipe 3 is a curve, and all the other are identical with embodiment 1.
