Abstract
The invention discloses an anus dilator base component, comprising an anus dilator base, wherein the an anus dilator base comprises a body and a wide edge dilating outwards; the wide edge is connected with the near end of the body; and the body comprises a group of anus dilating pieces which are arranged in a surrounding manner. The anus dilator base component also comprises a driving device, wherein the driving device comprises a drive rod and a tapered cap connected with the far end of the drive rod; and the bottom end of the tapered cap is provided with a furling slot. The component can gradually and controllably dilate the anus and the anal tube of the patient and can ensure the anal sphincter to adapt to the amplitude of spreading the anus by the body of the novel anus dilator, thus avoiding anal fissure and alleviating the pains of the patient. The component can be widely applied to surgery.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate in particular to the anus dilator seat assembly that a kind of surgical operation is used.
Background technology
When anorectal surgical is done inspection, diagnosis or operative treatment, need open anus earlier, and then put into other inspections or therapeutic device.The instrument of opening anus commonly used at present is an anus dilator seat, and its inflexible cylinder body is used for anus is strutted, and hollow space constitutes the passage that other apparatuses enter, and during use, inserts anus from cylindric end, because the diameter of anus dilator seat is bigger usually.Diameter reaches more than 30 millimeter, is not easy to enter anus, and the doctor can insert finger earlier usually, and two handss firmly outwards strut anus, and then anus dilator seat is inserted anus then.Because the doctor is with finger pre-expansion anus the time, through regular meeting because moment exerted oneself macrolesion patient's anal sphincter, make patient be subjected to unnecessary injury.
Summary of the invention
Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of anus dilator seat assembly that can avoid anal fissure.
Purpose of the present invention will be achieved by the following technical programs:
A kind of anus dilator seat assembly is used for the expansion of anus and anal canal, comprises anus dilator seat, and described anus dilator seat comprises body and the broadside that extends out, and described broadside is connected in the near-end of described body, and described body comprises one group around the expansion anus sheet of arranging; Described expansion anus holder assembly also comprises a driving device, and described driving device comprises a drive rod and be connected the tapered cap of the far-end of described drive rod that the bottom of described tapered cap is provided with one and draws the space in; Described anus dilator seat assembly optionally is in two states,
A) original state: described driving device is through described anus dilator seat, and the far-end of described expansion anus sheet draws in described gathering space, and the external diameter of the far-end of described body is less than the external diameter of its near-end;
B) expansion state: the external diameter of the near-end of described body equals the external diameter of its far-end.
Further, the inwall of the far-end of described body is provided with an annular groove in the same way, described anus dilator seat assembly comprises that also one can be arranged at the slip ring in the described groove in the same way, the height of described slip ring equals the height of described groove in the same way, and the internal diameter of the groove in the same way when its external diameter equals described body and is in expansion state, the internal diameter of described slip ring is equal to or greater than the external diameter of described tapered cap bottom surface.
Further, the near-end of described drive rod is provided with the handle of a collar plate shape.
Further, described body comprises that 8 are expanded the anus sheets, expands the anus sheet and is arranged on the body uniformly, and encompass one cylindric.
Compared with prior art, beneficial effect of the present invention is: can be so that patient's anus and anal canal little by little increase, make anal sphincter adapt to the amplitude that body strutted of novel anus dilator, thereby can avoid the generation of anal fissure phenomenon, alleviated patient's misery.
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.

The specific embodiment
Shown in Fig. 1-7, anus dilator seat assembly of the present invention comprises anus dilator seat 1, the broadside 11 that anus dilator seat 1 comprises body 12 and extends out, and broadside 11 is connected in the near-end of described body; Body 12 comprises that 8 are expanded anus sheets 123, expands the anus sheet and is arranged on the body equably, and encompass one cylindricly, and the distance between the adjacent expansion anus sheet 123 is the 1-5 millimeter, preferred 2mm; Described expansion anus holder assembly also comprises a driving device 2, driving device 2 comprises a drive rod 22, be connected drive rod 22 far-end tapered cap 21 and be connected the handle 23 of collar plate shape of the near-end of drive rod 22, the bottom of tapered cap 21 is provided with one and draws the space in; Described anus dilator seat assembly optionally is in two states,
A) original state: described driving device is through anus dilator seat 1, and the far-end that expands anus sheet 123 draws in described gathering space, and the external diameter of the far-end 121 of body 12 is less than the external diameter of its near-end 122, thereby makes the far-end 121 of body 12 play the effect of guiding;
B) expansion state: the external diameter of the near-end 122 of body 12 equals the external diameter of its far-end 121, and at this moment, it is big that the external diameter of far-end 121 becomes, thereby plays the effect of expansion anus or anal canal.
Described far-end is meant in use, from operator's end far away; Described near-end is meant in use, from the nearer end of operator.
The inwall of the far-end 121 of body 12 is provided with an annular groove in the same way 124, described anus dilator seat assembly comprises that also one can be arranged at the slip ring 3 in the groove in the same way 124, the height of slip ring 3 equals the height of groove 124 in the same way, and the internal diameter of the groove in the same way 124 when its external diameter equals body 12 and is in expansion state, the internal diameter of slip ring 3 is equal to or greater than the external diameter of tapered cap 21 bottom surfaces.When reality was used, slip ring 3 was enclosed within on the drive rod 22, push in the same way groove 124 along drive rod 22 in.When expanding ability that anus sheet 123 recovers deformation when being enough to offset the contractility of anal sphincter, slip ring 3 can be placed in the same way in the groove 124, thereby address this problem well.
The operation principle of anus dilator seat assembly of the present invention is: at first, the anus dilator seat 1 that will be under the original state inserts in the patient's anus; Then, fix body 12, promote drive rod 22 lentamente forward and break away from described gathering space up to the far-end that expands anus sheet 123; At last, slowly push in the same way in the groove 124, take out driving device 3 being enclosed within slip ring 3 on the drive rod 22.Because during original state, the far-end that expands anus sheet 123 draws in described gathering space, make the body 12 that enters the intravital anus dilator seat 1 of patient when initial roughly be conical; And himself flicks or strutted by slip ring 3 after, roughly cylindrical, so just can get ready for follow-up operation.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within protection scope of the present invention.
