Description
Technical field
This utility model relates to a kind of medical instruments field, particularly relates to a kind of intra-uterine dilator for gynecological's metreurysma.
Background technology
Gynecologial examination mainly comprises general physical checkup, abdomen examination and pelvioscopy, checks the situation of the other tissue in pudendum, vagina, cervix uteri and uterus, fallopian tube, ovary and palace and pelvic cavity inwall.Main Function makes early diagnosis, prevention and early treatment to some gynaecopathias.Need when generally carrying out Checking and diagnosis to uterus to expand palace, the medical apparatus and instruments expanding palace use is at present intra-uterine dilator.
The intra-uterine dilator that Present Domestic hospital generally adopts, be a kind of old-fashioned polytypic intra-uterine dilator, an intra-uterine dilator represents No. half, as No. 4,4.5 number, No. 5, No. 5.5 etc., each operation often will be changed and severally just can reach desirable expansion palace requirement to tens intra-uterine dilators, due to the pull back and forth of intra-uterine dilator, so operation receiveing person is very painful, easily cause infection again, and operating time is longer simultaneously.Patent Office of the People's Republic of China in the application number that December in 1992 is announced on the 23rd be 92209941.3 multiplex intra-uterine dilator for artificial abortion it by expansion palace, left and right leaf, scale adjusting knob is formed, it is intra-uterine dilator that key is that palace leaf leading portion is expanded in left and right, posterior segment uses as handle, under the control of scale adjusting knob, natural folding, expands No. 20 to from No. 4.But because this utility model only has left and right to expand palace blade, only play stretching dilating effect to cervix uteri mouth when expanding palace, can not carry out globally expanding to cervix uteri mouth, operation receiveing person still feels more painful, and easily shines into injury to cervix uteri mouth.Patent Office of the People's Republic of China is that the intra-uterine dilator for artificial abortion of 200320107294.5 is by four expansion palace blades in the application number that on November 22nd, 2003 announces, uterine-expanding rod, handle is formed, and its similar is in umbrella shape, strut and four blades evenly can be expanded, but because intra-uterine dilator will insert cervix uteri, determine that its diameter is smaller, be generally not more than 5mm, be difficult to make this structure in actual processing, even if can machine, its insufficient strength, is easily shunk the pressure conquassation produced by cervix uteri.
Another kind of water level intra-uterine dilator, be placed in advance in cervix uteri, expand by absorbing moisture the effect reaching and expand palace, but it needs intra-uterine dilator to be placed in cervix uteri to reach 0.5-1h, for patient and doctor's obvious time too very long, add operating time, add the misery of patient.
Summary of the invention
The purpose of this utility model is to provide one and quick and precisely can completes and reduce patient suffering and injury, and the intra-uterine dilator easily recovered.
This utility model is achieved by the following technical solution: a kind of intra-uterine dilator, comprise: uterine-expanding rod, handle, adjusting nut and mount pad, described mount pad and handle are hollow structure, mount pad is fixed on the front end of handle, described uterine-expanding rod is made up of push rod, multiple sub-uterine-expanding rod and elastic overcoat, described push rod is positioned at the center of sub-uterine-expanding rod, in sub-uterine-expanding rod and push rod are wrapped in by elastic overcoat, described push rod is connected with adjusting nut with bottom after handle through mount pad, is connected bottom described handle by screw thread with adjusting nut.
Further, described sub-uterine-expanding rod is fixed on mount pad by straight pin.
Further, spring is provided with between described push rod lower end and mount pad.
Further, described handle there is scale.
Further, described sub-uterine-expanding rod realizes expanding by the inclined-plane of push rod and sub-uterine-expanding rod inclined-plane.
Further, spring washer is had between described straight pin and mount pad.
This utility model compared to existing technology, has following beneficial effect:
1. intra-uterine dilator uterine-expanding rod of the present utility model is made up of four sub-uterine-expanding rod, so when opening, cervix uteri mouth uniform force, avoid cervix uteri mouth muscular injuries, institute operation receiveing person misery is little, and cervix uteri also easily recovers.
2. intra-uterine dilator handle of the present utility model there is scale, expand palace size by the visual control of adjusting nut doctor, realize accurately expanding palace.
3. intra-uterine dilator uterine-expanding rod peripheral hardware of the present utility model flexible overcoat protection muscle is to prevent Muscular injuries.
4. the sub-uterine-expanding rod of intra-uterine dilator of the present utility model realizes expanding by former and later two inclined-planes of push rod and sub-uterine-expanding rod inclined-plane, the support in all acceptor center push rod faces before and after sub-uterine-expanding rod, thus decreasing sub-uterine-expanding rod, to be out of shape the expansion palace size brought inaccurate.

Wherein: 1-push rod, 2-uterine-expanding rod, 3-mount pad, 4-straight pin, 5-spring, 6-handle, 7-adjusting nut, 8-spring washer, 9-elastic overcoat, 1a-uterine-expanding rod back bevel, 1b-uterine-expanding rod front bevel, 5a-push rod back bevel, 5b-push rod front bevel.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described.
As shown in the figure.A kind of intra-uterine dilator, comprise: uterine-expanding rod, handle, adjusting nut and mount pad, described mount pad and handle are hollow structure, mount pad is fixed on the front end of handle, described uterine-expanding rod is made up of push rod, four sub-uterine-expanding rod and elastic overcoat, push rod is positioned at the center of sub-uterine-expanding rod, in sub-uterine-expanding rod and push rod are wrapped in by elastic overcoat, thus four sub-uterine-expanding rod is evenly expanded outwardly.
Described push rod is connected with adjusting nut with bottom after handle through mount pad, is connected bottom described handle by screw thread with adjusting nut.
Further, described sub-uterine-expanding rod is fixed on mount pad by straight pin.
Further, spring is provided with between described push rod lower end and mount pad.
Further, described handle has scale, can be easy to by adjusting nut the size being expanded to needs, maximal regulated scope can reach push rod diameter dimension.
Further, described push rod realizes expanding by the inclined-plane that former and later two gradients are identical with sub-uterine-expanding rod, ensures the concordance of expanded dimension before and after uterine-expanding rod.
Further, spring washer is had between described straight pin and mount pad.
The work process of a kind of intra-uterine dilator of this utility model is as follows:
Uterine-expanding rod is made up of four sub-uterine-expanding rod 2 and push rod, when doctor uses this intra-uterine dilator, uterine-expanding rod is in closure state, now uterine-expanding rod is inserted cervix uteri, rotate the adjusting nut 7 bottom regulating handle 6, push rod 1 is moved forward, before and after before inclined-plane 5b, 5a move along inclined-plane 1b, 1a before and after sub-uterine-expanding rod 2, thus sub-uterine-expanding rod 2 is evenly expanded, sub-uterine-expanding rod 2 is fixed on mount pad 3 by straight pin 4, and making it possess pretightning force by spring washer 8, push rod 1 is under the elastic force of spring 5 simultaneously, possesses the pretightning force of reply.Handle 6 holds place for doctor, and adjusting nut 7 in connection, determines the size needing to expand palace by screw thread by the scale rotated on regulating handle 7.
