Abstract

The utility model discloses a rectum and sigmoid intra-cavity surgical operation microscope, which comprises a microscope tube composed of three arc lenses, wherein an expanding arm is horizontally and respectively fixed at the corresponding position of the upper ends of two lenses, and each expanding arm is provided with an upward expanding bar; an expanding plate bar is horizontally fixed at the upper end of the other lens, and the front end of an expanding tension bar is connected with the front lower part of the expanding plate bar by a shaft; a fulcrum shaft of a scissor handle is sheathed in a sliding groove of the expanding tension bar, and the straight end of the expanding arm is inserted into a bore of the head of the scissor handle. The utility model has the advantages that the lenses can expand simultaneously, the expanding distance of the head end can exceed that of the tail end, the operation field and space is large, the utility model can reach to the sigmoid colon with enough length, and the use is convenient.

Description

Rectum, sigmoid colon intracavity operation mirror

This utility model relates to a kind of usefulness visual or the take pictures chamber of inspection human body or the instrument of pipe, is a kind of endoscope, a kind of specifically rectum, sigmoid colon intracavity operation mirror.

Existing rectoscope, romanoscope are elongated tubular, not expansible mirror chamber, and an end has ring flange, and during use, the visual field is little, with the inconvenience that operates.A kind of three pages of anoscopes are also arranged, can three pages expansion simultaneously, but expansion distance equates up and down, owing to be subjected to the restriction of anus diameter, impossible expansion is very big, and often the enteric cavity expansion is dissatisfied, can only be used for the simple operation of distal rectal and anus, be difficult to use in the deep and complicated operation.

The purpose of this utility model is: provide a kind of three pages of eyeglasses to expand simultaneously, and the head end expansion distance can surpass rectum easy to use, the sigmoid colon intracavity operation mirror of tail end distance.

The technical solution of the utility model is: rectum, sigmoid colon intracavity operation mirror comprises the mirror pipe that three pages of Arc lenses are formed, wherein on the correspondence position of two pages of eyeglasses upper end respectively level to fixing an expansion arm, each fixes an expanding bar that makes progress on the expansion arm, another page eyeglass upper end level of mirror pipe is to fixing an expanding plate bar, the front end of expansion pull bar is below the front portion that spool is connected the expanding plate bar, the front portion of expansion pull bar has two layers up and down, go up sliding tray should be arranged for two layers up and down, the fulcrum shaft of scissors handle is contained in the sliding tray, the both sides of scissors handle all flexibly connect with connecting rod with the tail of expansion pull bar, the straight end of above-mentioned two expansion arm inserts respectively in the hole of two haircuts of scissors handle front end, and rotatable.Expanding plate bar and the scissors handle both sides of said fixing on another page eyeglass flexibly connect with connecting rod.Scissors handle afterbody has laterally relative hole, and wherein there is female thread in 1 hole, and adjusting screw(rod) is through in two holes, and an end has block, and the other end has the handle piece.Two expansion arm that are fixed on two pages of eyeglass upper ends are G shape.The top that is separately fixed at two expanding bars on the expansion arm connects with bearing pin.The structure that the binding of expansion pull bar front end and expanding plate bar is adopted is: the front portion of expanding plate bar has two earholes downwards, and two earholes insert in the groove of expansion pull bar front end, and link with bearing pin.Be used for fixing the square fixed block of light guide bundles on the expanding plate bar in addition.

The utility model has the advantages that: three eyeglasses of operation mirror can expand simultaneously and the head end expansion distance can substantially exceed tail end, be not subjected to the restriction of anus diameter during use, the visual field and operation technique space are big, also can do longlyer, can reach sigmoid colon, thereby can do complicated operation at rectum, sigmoid colon intracavity, easy to use.

Further narrate the technical solution of the utility model below in conjunction with drawings and Examples:

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 3 is expansion pull bar and handle arrangement sketch map.

Embodiment 1:

Referring to accompanying

drawing

1,2,3, rectum, sigmoid colon intracavity operation mirror comprise 1,2,3, three eyeglasses of Arc lens to close up the back blunt for complete pipe, head circle.Two G shape expansion arm 4 are level to the upper end that is symmetrically welded at mirror page or

leaf

1,2, and it is directly held and is turning cylinder 5, and expander bar 24 is upwards welded at the turning of expansion arm 4 respectively, and expander bar 24 tops are porose to be connected with bearing pin, movable.Expansion sheet bar 23 is level to the upper end that is welded on mirror page or leaf 3, is welded with two downward metal ears 22 near symmetry below expansion sheet bar 23 head ends, relative hole about the ear middle part is drilled with, and pair of straight angled metal piece 10, fixedly light guide bundles are upwards welded in sheet bar 23 middle parts.Two metal ears that make progress 14 of afterbody welding of expansion sheet bar 23, the middle part of ear is jagged, and respectively there is forward and backward vertical aperture at the proximal edge place, and the slightly curved also foraminous connecting rod 13 of an end is connected with ear 14 usefulness pins.The head end of the expansion pull bar 15 of mirror page or leaf 3 has groove 7, and relative hole about having, be fixed in metal ear 22 insertion grooves 7 below the expansion sheet bar 23 and and connect with bearing pin, two layers up and down of the forward part of expansion pull bar 15, on the levels to sliding tray 8 should be arranged, the fulcrum shaft 9 of scissors handle 18 just in time is contained in the sliding tray, and connecting rod 16 usefulness bearing pins and screw are connected both sides mider hole 12 places and expansion 20 places, pull bar afterbody hole of scissors handle.The straight end turning cylinder 5 of G shape expansion arm inserts in the hole 6 of two haircuts of handle 18 front ends.Inboard, handle 18 middle part is welded with the relative metal ear of level 11 respectively, and ear 11 middle parts are jagged, and vertical aperture before and after having, and connecting rod 13 other ends are connected this with pin.Scissors handle 18 both sides afterbodys have laterally

relative hole

17,21, and there is female thread in hole 21, and adjusting screw(rod) 19 is through in two holes, and an end has block, and the other end has the handle piece, and bar 19 is rotatable in the hole, but can not extract out.

Above-mentioned G shape expansion arm also can be straight shape.
