Abstract

The invention discloses an anus expanding device, which is used for expanding the anus and the anal tube. The anus expanding device comprises a positioning piece, a rotating piece and a rotating device, wherein the rotating piece is matched with the positioning piece and can rotate along an inner wall of the positioning piece; the rotating device is used for making the rotating piece rotate along the inner wall or an outer wall of the positioning piece; the positioning piece comprises a first body and an outwards expanded first wide side which is connected with a near end of the first body; and the rotating piece comprises a second body and an outwards expanded second wide side which is connected with a near end of the second body. The anus expanding device has the advantages that: the anus and the anal tube of a patient can be gradually and controllably enlarged, and the anal sphincter adapts to an amplitude that an anus expanding device expands the anal sphincter before the anus expanding device base is inserted, so that the anal fissure phenomenon can be avoided, and the pain of the patient is alleviated. The anus expanding device can be widely applied to a surgical operation.

Description

Anus-expanding unit

Technical field

The present invention relates to the anus-expanding unit that a kind of surgical operation is used, belong to technical field of medical instruments.

Background technology

When anorectal surgical is done inspection, diagnosis or operative treatment, need first anus to be strutted, and then put into the surgical instruments that other are used for inspection or treatment.The surgical instruments that struts anus commonly used is anus dilator seat at present, comprise a columnar body and the application of force convex shoulder that is positioned at the body afterbody, the cylinder body of its rigidity can strut anus, and the hollow space in cylinder consists of other surgical instrumenties and enters the interior passage of patient body.During use, the body of anus dilator seat is slowly inserted anus by its front end until anal canal, due to the diameter of the cylinder body of anus dilator seat larger (generally reaching more than 30 millimeter) usually, so anus dilator seat is not easy to enter anus.Existing common way is that the doctor can first insert patient's anus with finger, and then two handss firmly outwards strut, then anus dilator seat is inserted anus.Due to the doctor with finger pre-expansion anus the time, often can the anal sphincter damage patient cause anal fissure because moment exerts oneself excessive, make patient be subject to unnecessary injury.

Summary of the invention

The specific embodiment

As shown in Fig. 1-7, a kind of anus-expanding unit of the present invention comprises keeper 1, matches with keeper 1, and can be along the revolving part 2 of the inwall rotation of keeper 1 and be used for making the revolving part 2 can be along the rotary apparatus of the inwall rotation of keeper 1; Keeper 1 comprises the first noumenon 11 and is connected in first broadside 12 that extends out of the first noumenon 11 near-ends; Revolving part 2 comprises the second body 21 and is connected in second broadside 22 that extends out of the second body 21 near-ends; The external diameter of revolving part 2 equals the internal diameter of keeper 1; Described a kind of anus-expanding unit optionally is in two states,

A) original state: revolving part 2 is close to the inwall of keeper 1, and revolving part 2 and keeper 1 fully overlapping, certainly, under original state, revolving part 2 and keeper 1 also can overlap;

B) expansion state: the outer rim of revolving part 2 is connected in keeper 1, and the first noumenon 11 and the second body 21 match and form the cylinder type of hollow.Certainly, also can coordinate the cone cylindrical structure that forms hollow.

Described rotary apparatus comprise the far-end that is arranged on the first broadside 12 arc the first groove 121 and be arranged on first projection 221 of arc of the far-end of the second broadside 22, the first projection 221 can be in the first interior rotation of groove 121, and the two ends of the first projection 221 all stretch out in outside the second broadside 22; Described rotary apparatus also comprise the near-end that is arranged on the first broadside 12 arc the second groove 122 and be arranged on second projection 222 of arc of the near-end of the second broadside 22, the second projection 222 can be in the second interior rotation of groove 122, and the two ends of the second projection 222 all stretch out in outside the second broadside 22; When described original state, the first projection 221 and the second projection 222 are positioned at respectively the first groove 121 and the second groove 122 fully; When described expansion state, the two ends that the first projection 221 is stretched out are connected in respectively the two ends of the first groove 121, the two ends that the second projection 222 is stretched out are connected in respectively the two ends of the second groove 122, form the columnar structured of hollow thereby make the first noumenon 11 and the second body 21 to match.

The two ends of the first groove 121 are respectively arranged with pin 224, position in the correspondence at the two ends of the first projection 121 is respectively arranged with hole clipping 223, when described expansion state, the pin 224 that all stretches out in the first broadside 12 is connected in respectively in hole clipping 223, thereby plays fixing described columnar structured effect.Certainly, can also establish a spring between the inwall of pin 224 and the first groove 121, when pin 224 alignd with hole clipping 223, the elastic force of spring can drive pin 224 from being advanced into described hole clipping 223, saves the action of doctor's manual actuation pin.

Respectively be provided with the opening 3 for perform the operation observation or operative treatment of a rectangle on the first noumenon 11 and the second body 21.Certainly, also can be provided with opening 3 on one of the first noumenon 11 and second body 21, opening 3 also can be set to shape trapezoidal or that other are suitable.

The below simply introduces use procedure of the present invention:

At first, the anus-expanding unit under described original state is inserted patient's anal; Then, fix keeper 1, rotate lentamente this revolving part 2, until the two ends that the first projection 221 is stretched out are connected in respectively the two ends of the first groove 121, the two ends that the second projection 222 is stretched out are connected in respectively the two ends of the second groove 122, and are more smooth in order to make rotation, can coat the smooth thin film of one deck at the outer wall of this apparatus, make apparatus can slip over smoothly mucosa in tissue, mucosa has not been produced damage; At last, pin 224 is connected in respectively the interior fixing described revolving part 2 of corresponding hole clipping 223 and keeper 1, thereby has formed the cylinder type of hollow, for follow-up operation technique is got ready.Due to when the original state, this anus-expanding unit only has half of original anus-expanding unit, so when entering in the patient body, its amplitude that struts patient's anal sphincter is also less, so reached purpose of the present invention.And then, when it is in expansion state, forming an anus-expanding unit same as the prior art, the doctor can carry out follow-up operation or medical observation with it, can not change doctor's operation custom, so have good practical value.

The present invention still has numerous embodiments, and for example: opposite with most preferred embodiment of the present invention, revolving part 2 is arranged on the outer wall of keeper 1, along the outer wall rotation of keeper 1.All employing equivalents or equivalent transformation and all technical schemes of forming are within all dropping on protection scope of the present invention.
