Abstract
The utility model relates to an inserted joint structure to link an endoscope and an operating part. A plug and a telescope are coaxially connected with a guide pipe, which can not generate the bending moment; compared with the current plugs of the inserted joint endoscopes, the utility model has the advantages of reasonable structural design, long service life, no water leakage, more convenient leakage, stability, reliability and so on.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments draw bail, specifically is the connected structure of a kind of endoscope and operation part.
Background technology
Endoscope is that a kind of viewing system in the therapeutic device is hindered by Wicresoft, is widely used in each section office by hospital.The connecting mode of current endoscope and operation part has two kinds, and a kind of is plug-in type, and another kind is a twist lock type.Advantages such as it is simple that plug-in type has connection, convenient.Endoscope of the prior art plug as shown in Figure 1, it is by mirror pipe 1`, microscope base 2`, inserted link 3` and guide pipe 4` form, inserted link 3` is a little bar that is contained on the microscope base 2`, with mirror pipe 1` and guide pipe 4` disalignment.When the bigger and heavier video camera of volume (CCD) optical interface is associated in eyepiece hood 5` and goes up, be easy to generate and connect unstablely, to leak during operation, phenomenon such as mirror pipe 1` is flexible influence operation technique, and service life is short.Plug-in type endoscope all adopts this plug form both at home and abroad at present.
Summary of the invention:
In order to overcome the deficiency that above-mentioned endoscope plug exists, this utility model provides a kind of long service life, connects more convenient, more stable endoscope's connected structure.
The technical solution adopted in the utility model is: plug is fixed on the microscope base, and is connected with mirror pipe and guide pipe are coaxial, can not produce moment of flexure; It is characterized in that: guide pipe is contained in plug head, play the guiding role, and seals with the O type circle that is contained on the socket, prevents to leak; O type circle compresses with trim ring, prevents play.Plug is made flat type and groove is arranged; Flat type lateral symmetry respectively has a facet and a big plane; Big plane control plug rotates; Facet control plug can only insert along a direction.The ball that is contained on the socket is stuck in the plug slot, and the control plug moves forward and backward; The ball spring compression prevents to become flexible; Jackscrew regulating spring elastic force size.

Fig. 3 is a plug A-A profile.
Fig. 4 is endoscope's plug and socket coupling arrangements sketch map.
The specific embodiment
As Fig. 2～shown in Figure 4, plug 3 and guide pipe 4 and 1 coaxial connection of mirror pipe, and fixing with microscope base 2.Guide pipe 4 is contained in plug 3 front ends, play the guiding role, and seals with the O type circle 10 that is contained on the socket 5, prevents to leak; O type circle 10 usefulness trim rings 9 compress.Plug 3 is made flat type and is had groove 3a, and flat type lateral symmetry respectively has a facet 3b and a big plane 3c, and big plane 3c control plug 3 rotates; Facet 3b control plug 3 can only insert along a direction.The ball 6 that is contained on the socket 5 is stuck among the plug slot 3a, compresses with spring 7, prevents to become flexible.And then control plug 3 moves forward and backward; With the elastic force size that is contained in jackscrew 8 regulating springs 7 on the socket 5.Socket 5 is connected with operation part.
This utility model compared with prior art has reasonable in design, and long service life is water-tight, connects advantages such as more convenient, reliable and stable.
