Abstract
The utility model relates to a colonoscopy lobulated anus eurynter for anus expanding so that the end of a colono-fiberscopy can be inserted in the anus. The utility model comprises a casing (1), an inner core (2) and a handle (3), wherein, the casing (1) is composed of a semicircular left lobe (4) and a semicircular right lobe (5); the handle comprises a left handle (6) and a right handle (7). The left handle (6) is connected with the left lobe (4), and the right handle is connected with the right lobe (5). The inner core (2) is composed of a core handle (8) and a sliding surface hammer (9) of the handle end. The core handle (8) is connected with the sliding surface hammer (9) of the handle end. The utility model can effectively lighten the pain and uncomfortable feeling of patients during colono-fiberscopy examination, and the damage degree of the colono-fiberscopy can be lightened.
Description
This utility model relates to and a kind ofly is used to expand anus so that the colonoscopy branch blade profile anal dilator that insert the fibro-colonoscope end belongs to medical apparatus and instruments.
The present optical system of hospital's fibro-colonoscope (being called for short fine mirror) commonly used, mainly light beam and the video beam of forming by lens and about 20,000 leaded light glass fiber.The crisp rapid wear of these glass fibre matter causes after the fracture stain occurring inevitably on reflection, and fine mirror can not use when surpassing 200 stains.In the prior art, do colonoscopy, most methods of directly the mirror end being inserted by anus that adopt.Because patient's psychentonia, the anus inflammatory stimulus causes the sphincterismus contraction in addition, makes and inserts the mirror difficulty; Can make the distortion of mirror end when firmly inserting, the glass optical waveguide fibre fracture, a bent rubber elongates damaged because of inserting mirror repeatedly; Usually check that 200 examples are inferior, about 30 of video beam fractures, a simultaneously bent rubber breaks.In addition, directly inserting mirror can stimulate anus to cause patient's pain discomfort.
The purpose of this utility model provides a kind of colonoscopy branch blade profile anal dilator, uses this dilator, is convenient to the insertion of colonoscope end, can alleviate patient's the pain sense of discomfort and the damaged condition of fine mirror.
The purpose of utility model realizes according to following technical proposals.
Colonoscopy divides the blade profile anal dilator, structure comprises housing, inner core and the handle that is connected with housing, housing is that semicircular lobus sinister and lobus dexter two parts constitute by the cross section, the structure of handle comprises left handle and right handle two parts, left side handle is connected with lobus sinister, and right handle is connected with lobus dexter, and inner core is connected to form by core handle and pommel sliding surface hammer two parts, the diameter of hammer increases gradually from its end to end, and the external diameter when its maximum gauge is roughly closed with housing is consistent.
When about housing during two leaf interlocks, promptly when housing was closed, the shape of housing was hollow cylindrical.During use, with inner core cover in housing.Have only when about two leaves when being separated, inner core could pass in housing.
The using method of dividing the blade profile anal dilator.At first with inner core cover in housing; After the dilator that scribbles lubricant inserted anus, manual handle separated housing two leaves, takes out inner core, again with fine mirror by inserting the rectum lower end in the housing; Withdraw from the dilator housing, manual handle makes housing two leaves separately then, and housing is taken off from shank.After dilator takes off, promptly do not influence the effective length of mirror body and check effect.The fibre mirror does not directly stimulate anus can alleviate patient's pain sense of discomfort, because dilator makes anal sphincter lax with the anus expansion, thereby the insertion of fine mirror just is easy to smooth.
The colonoscopy branch blade profile anal dilator that this utility model provides can alleviate the pain sense of discomfort of patient when fine spectroscopy effectively, and can alleviate the damaged condition of fine mirror effectively, prolongs the service life of fine mirror.It is inferior to use this dilator to make fine spectroscopy 2,000 examples, and video beam damages only 3-5 root, and a bent rubber is intact, and the patient does not have significant discomfort.This dilator structure is comparatively simple, safe and reliable, easy to operate.
Below in conjunction with accompanying drawing this utility model is elaborated.
Accompanying drawing 1 is the schematic appearance of the branch blade profile dilator that provides according to this utility model, and accompanying drawing 2 is structural representations of Fig. 1 middle shell and handle, and accompanying drawing 3 is structural representations of inner core among Fig. 1.
Colonoscopy divides the blade profile anal dilator as shown in drawings, its structure comprises housing (1), inner core (2) and the handle (3) that is connected with housing, housing (1) is that semicircular lobus sinister (4) and lobus dexter (5) two parts constitute by the cross section, the structure of handle (3) comprises left handle (6) and right handle (7) two parts, left side handle (6) is connected with lobus sinister (4), right handle (7) is connected with lobus dexter (5), inner core (2) is connected to form by core handle (8) and pommel sliding surface hammer (9) two parts, the diameter of hammer (9) increases gradually from its end to end, and the external diameter when its maximum gauge is roughly closed with housing is consistent.Shell end is hammered combining between (9) into shape with sliding surface and should be tried one's best continuously smooth.
As shown in Figure 3, dilator handle (3) is located at the end of housing (1), and left handle (6) and right handle (7) intersect, and at its infall axle (10) is set, and is provided with back-moving spring (11) between the handle of the left and right sides.Hold fixed handle and can make housing two leaves separately, release handle, under action of reset spring, housing two leaves are interlock, about the big I of two leaves unequal, can be as lobus sinister, but during two leaf interlocks, the shape of housing is cylinder greater than lobus dexter.
Housing, inner core and handle all adopt metal material to make.Usually the sliding surface hammer is long 2 centimetres, 1.5 centimetres of maximum gauges, and the long 5 lis of bodies of housing, long 15 centimetres of left and right sides handle, the internal diameter when housing at utmost opens is not less than 1.5 centimetres.
Claims (2)
1, a kind of colonoscopy divides the blade profile anal dilator, structure comprises housing (1), inner core (2) and the handle (3) that is connected with housing, it is characterized in that: housing (1) is that semicircular lobus sinister (4) and lobus dexter (5) two parts constitute by the cross section, the structure of handle (3) comprises left handle (6) and right handle (7) two parts, left side handle (6) is connected with lobus sinister (4), right handle (7) is connected with lobus dexter (5), inner core (2) is connected to form by core handle (8) and pommel sliding surface hammer (9) two parts, the diameter of hammer (9) increases gradually from its end to end, and the external diameter when its maximum gauge is roughly closed with housing is consistent.
