Abstract
The invention discloses an anus pre-dilator, comprising a ring and at least two dilation pieces symmetrically arranged on the outer edge of the ring, wherein the dilation pieces are hinged on the outer edge of the ring by a hinge device arranged on the ring; each dilation piece comprises a working part and an operating part which are connected and respectively arranged at the two sides of the hinge device; the top ends of the working parts draw close to each other in the working state and the space between the top ends is less than the diameter of the ring. The machine 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 anus dilator base before the anus dilator is inserted into the anus dilator base, thus avoiding anal fissure and alleviating the pains of the patient. The anus dilator can be widely applied to surgery.
Description
Technical field
The present invention relates to the anus that a kind of surgical operation uses and expand device in advance, belong to technical field of medical instruments.
Background technology
When anorectal surgical is done inspection, diagnosis or operative treatment, need earlier anus to be strutted, and then put into other and be used to the surgical instruments checking or treat.The surgical instruments that struts anus commonly used at present is an anus dilator seat; Comprise a columnar body and the application of force convex shoulder that is positioned at the body afterbody; Its inflexible cylinder body can strut anus, and the intravital hollow space of cylinder then constitutes other surgical instrumenties and gets into the intravital passage of patient.During use, the body of anus dilator seat is slowly inserted anus until anal canal by its front end, because the diameter of the cylinder body of anus dilator seat bigger (generally reaching more than 30 millimeter) usually, so anus dilator seat is not easy to get into anus.Existing common way is that the doctor can insert patient's anus with finger earlier, and two handss firmly outwards strut then, again anus dilator seat are inserted anus.Because when the doctor expanded anus in advance with finger, the anal sphincter damage patient caused anal fissure because moment exerts oneself excessive through regular meeting, makes patient receive 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 of anal fissure of can avoiding and expands device in advance.
The object of the invention will be achieved through following technical scheme:
A kind of anus expands device in advance, is used for the predilation of anus and anal canal, comprises an annulus and at least two expansion parts of being located at said annulus outer rim symmetrically, and said expansion part all is articulated in said annulus outer rim through the articulated mounting be located on the said annulus; Said expansion part comprises continuous operate portions and operating portion, is located at the both sides of said articulated mounting respectively; The top of said operate portions is drawn close down in working order each other, the diameter of spatial maximum linear distance less than said annulus that form.
Further, said operating portion comprises driving section that is connected in said operate portions and the grip part that is connected in said driving section, and the top of said grip part is outside divergent state each other, and the spacing between its grip part is greater than the maximum spacing between the corresponding driving section.
Further, be parallel to each other between the said driving section to form cylindric or expand outwardly and form the cone shape.
Further, said articulated mounting is pin-and-hole bindiny mechanism or ball holes mechanism.
Further, said operate portions is shaft-like or laminated structure.
Further, said operating portion is shaft-like or laminated structure.
Further, said anus expands device in advance and comprises four expansion parts that are articulated in said annulus outer rim symmetrically.
Further, the top of said grip part all be connected with one be used to insert finger finger ring.
Compared with prior art; Beneficial effect of the present invention is mainly reflected in: can be so that patient's anus and anal canal little by little, controllably increase; Before inserting anus dilator seat, can make anal sphincter adapt to the amplitude that can be strutted by anus dilator seat; Thereby can avoid the generation of anal fissure phenomenon, alleviate patient's misery.

Fig. 1 is the axonometric chart that anus of the present invention expands device in advance;
Fig. 2 is the front view that anus of the present invention expands device in advance;
Fig. 3 is the vertical view that anus of the present invention expands device in advance.
Among the figure:
1 annulus, 2 expansion parts, 21 operate portions
23 grip parts, 22 driving sections, 24 finger rings
25 articulated mountings
The specific embodiment
Shown in Fig. 1-3, anus of the present invention expands device in advance, comprises an annulus 1 and at least two expansion parts 2 of being located at annulus 1 outer rim symmetrically, and this expansion part 2 all is articulated in annulus 1 outer rim through the articulated mounting 25 be located on the annulus 1; Expansion part 2 comprises continuous operate portions 21 and operating portion, is located at the both sides of articulated mounting 25 respectively.The top of operate portions 21 is drawn close each other, and the circular space rectilineal interval of its formation is less than the diameter of annulus 1, and working as operate portions 21 like this needs insertion patient anus ratio to be easier to, and anus is pursued part expansion, not muscle injury.
Said operating portion comprises driving section 22 that is connected in operate portions 21 and the grip part 23 that is connected in driving section 22, and the top of grip part 23 is outside divergent state each other, forms horn-like space, and its distance each other is greater than the maximum spacing between the driving section 22.Preferably, be parallel to each other between the driving section 22, form cylindric space.
Among the present invention, articulated mounting 25 is pin-and-hole bindiny mechanism or ball holes mechanism.Because these mechanisms all are prior aries, therefore repeat no more at this.
In the present embodiment, said operate portions 21 and operating portion are rod-like structure.Certainly, operate portions 21 also can be laminated structure, and coats the slick thin film of one deck outside, during operate portions 21 expansion anuses, and the contact friction area of minimizing and skin, thus make preparatory expansion device get into the sense of discomfort that anus is easier and reduce friction and produce.
In the present embodiment, said anus expands device in advance and comprises four expansion parts 2 that are articulated in annulus 1 outer rim symmetrically, and this structural design meets the use habit of staff more, and simple in structure, is easy to make.
Preferably, the top of grip part 23 all be connected with one be used to insert finger finger ring 24, the medical worker can insert finger in the finger ring 24 in use, can freely control the amplitude of expanding, and is convenient to more operate.
Described expansion part is that elastomeric material is made, like elastic sheet metal, Metallic rod etc.
The use of the present invention once of following brief account:
At first, insert 4 finger rings of grip part with finger, hold preparatory expansion device and aim at anus, the operate portions 21 that anus is expanded in advance device gently is inserted into anal; Strut the grip part with finger, make its to around expansion, and then loosen, strut/loosen several times, adapted to the amplitude that can be strutted by anus dilator seat until anal sphincter; At last, take out anus and expand device in advance, insert anus dilator seat and carry out follow-up inspection or 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.
