Abstract
The utility model belongs to a nasal endoscope with adjustable visible range, belongs to medical instruments, and particularly discloses a nasal endoscope for extending into a nasal cavity for probing a nose with a refractor. The nasal endoscope comprises a mirror pipe and the refractor; the inner end, extending into the nose, of the mirror pipe is a probing end while the other end of the mirror pipe is an operation end; the refractor is arranged at the probing end of the mirror pipe; the basal endoscope is characterized by further comprising an outer sleeve pipe of which one end is a slope opening end; the outer sleeve pipe is sleeved at the outside of the mirror pipe; the probing end of the mirror pipe is adjacent to the slope opening end; the refractor has two connecting points; one connecting point is connected with the probing end; and the other connecting point is connected with the slope opening end. The nasal endoscope with the adjustable visible range has the advantages that the nasal cavity can be observed form multiple angles by only one nasal endoscope, and a doctor can operate from any angle to observe the nasal cavity after the nasal endoscope is inserted into the nasal cavity once. The nasal cavity can be observed from multiple angles without multiple nasal endoscopes, and the nasal endoscope does not need to be inserted into the nasal cavity of a patient by multiple times, so the pain of the patient is reduced and a nasal passage is prevented from being damaged.
Description
Technical field
This utility model belongs to the nose medical apparatus and instruments, particularly stretches into nasal cavity and enters the intranasal mirror of surveying intranasal with refracting telescope.
Background technology
Refracting telescope and the mirror pipe of existing intranasal mirror are fixed, and are detection intranasal different parts, can only select the intranasal mirror of refracting telescope and the different bevel angles of mirror pipe.When practical operation, for surveying the intranasal different parts, will take out the bevel angle intranasal mirror of using, again inserting again intranasal with bevel angle intranasal mirror, multiple different bevel angle intranasal mirrors are inserted in nasal cavity so repeatedly, make patient very painful, also may damage nasal meatus.
Summary of the invention
The purpose of this utility model is to provide once to be inserted in nasal cavity, the intranasal mirror that can observe multi-angle in nasal cavity.
Structure of the present utility model is:
A kind of intranasal mirror of scalable visual range, comprise mirror pipe 1 and refracting telescope 2, the intranasal end that stretches into of mirror pipe 1 is end of probe 3, the other end is operating side 10, the end of probe 3 of mirror pipe 1 is provided with refracting telescope 2, it is characterized in that: also comprise a trocar sheath 4, the end that has of trocar sheath 4 is inclined-plane opening 5, trocar sheath 4 is enclosed within the outside of mirror pipe 1, the end of probe 3 of mirror pipe 1 and 5 neighbours of inclined-plane opening of trocar sheath 4, refracting telescope 2 has two junction points 6, and one of them junction point 6 is connected with end of probe 3, and another junction point 6 is connected with inclined-plane opening 5.
Trocar sheath 4 is enclosed within the outside of mirror pipe 1, makes the trocar sheath 4 generation displacement of reciprocally sliding in mirror pipe 1 outside.2 two junction points 6 of refracting telescope are connected in respectively on trocar sheath 4 and mirror pipe 1, when trocar sheath 4 and mirror pipe 1 have displacement, the bevel angle of refracting telescope 2 has and can change thereupon, insert it into that intranasal mirror in nasal cavity does not take out, do not change, same intranasal mirror just can be observed multi-angle in nasal cavity, reduce patient's misery, prevent from damaging nasal meatus.
That end that trocar sheath 4 connects refracting telescope 2 is inclined-plane, purpose is when an end of refracting telescope 2 is pulled to trocar sheath 4 the inside direction by mirror pipe 1, can not move trocar sheath 4 the insides to, and a part that prevents refracting telescope 2 is in trocar sheath 4 the insides, trocar sheath 4 blocks refracting telescope 2, reduces the observable scope of refracting telescope 2.The inclined-plane that is trocar sheath 4 is for when refracting telescope 2 changes inclination angle, makes refracting telescope 2 maintain maximum observable scope.
As long as trocar sheath 4 can be from the end of probe 3 of mirror pipe 1 to operating side 10, the doctor just can operate simultaneously in the operating side 10 of mirror pipe 1 trocar sheath 4 with from the 1 relative sliding displacement of mirror pipe, thereby change the inclination angle of refracting telescope 2, the range of observation of change refracting telescope 2.
Two junction points 6 of refracting telescope 2, lay respectively at this 90 ~ 180 round De Liangge positions, radian interval of two junction points, 6 places.Two junction points 6 that are refracting telescope 2 lay respectively at 90 ~ 180 round degree De Liangge positions, angle of these two junction points, 6 places.Between two junction points 6 of refracting telescope 2, at a distance of far away, refracting telescope 2 is better with the mechanical connection stability of trocar sheath 4 and mirror pipe 1.
Two junction points 6 of refracting telescope 2, lay respectively at this 180 round De Liangge positions, radian interval of two junction points, 6 places.Two junction points 6 of refracting telescope 2 lay respectively at 180 De Liangge positions, radian interval, and the mechanical connection of refracting telescope 2 and trocar sheath 4 and mirror pipe 1 is stablized best, is conducive to change the operation at refracting telescope 2 inclinations angle.
The bevel angle of trocar sheath 4 inclined-plane openings 5 is 30 ~ 60 degree, and namely the beveled tip 7 of inclined-plane opening 5 is 30 ~ 60 degree to the most advanced and sophisticated place of tube wall tube wall 9 angles of surface bottom 8 place diameters and beveled tip 7 place trocar sheaths 4; Trocar sheath 4 beveled tip 7 are provided with soft ball 12.Preferably trocar sheath 4 inclined-plane angles are 30 ~ 60 degree, make the inclined-plane of trocar sheath 4 not too sharp, are difficult for stabbing nasal cavity, the observation scope that makes again refracting telescope 2 have enough doctors to need.When preventing misoperation, the beveled tip 7 of trocar sheath 4 is stabbed nasal cavity, in beveled tip 7, soft ball 12 is set.
Two junction points 6 of refracting telescope 2, one of them junction point 6 is connected with the beveled tip 7 of trocar sheath 4 inclined-plane openings 5, and another junction point 6 is connected with corresponding mirror pipe 1 end of probe 3 of the surface bottom 8 of trocar sheath 4 inclined-plane openings 5.Two junction points 6 of refracting telescope 2 are located at respectively on the mirror pipe 1 of trocar sheath 4 beveled tip 7 and beveled tip 7 opposite faces, namely on the mirror pipe 1 of beveled tip 7180 degree positions.Be conducive to so most trocar sheath 4 is changed with mirror pipe 1 sliding transfer the inclination angle of refracting telescope 2.Also the Bao Yigen action bars 11, action bars 11 1 ends are connected with trocar sheath 4, action bars 11 other ends are positioned at 10 positions, operating side of mirror pipe 1, and the tube wall of mirror pipe 1 is provided with places restrictions on the cutting ferrule 12 that action bars 11 drops, and action bars 11 is through between the tube wall of cutting ferrule 12 and mirror pipe 1.The purpose of setting operation bar 11 is with action bars 11, to substitute the part of trocar sheath 4, reduces to insert the diameter of main pipe subdivision in nasal cavity, makes patient reduce misery.
Advantage of the present utility model: the multi-angle observation nasal cavity, as long as the intranasal mirror of a basic utility model once inserts in nasal cavity, the doctor is in the operating side of this intranasal mirror, and any angle that namely just can operate in outside nasal cavity in the certain angle scope is observed nasal cavity.Make the nasal cavity of its multi-angle observation need not a plurality of intranasal mirrors, also repeatedly the cue scope inserts patient's nasal cavity, reduces patient's misery, prevents from damaging nasal meatus.
