Description
Technical field
The present invention relates to endoscopic technique field, in particular to a kind of disposable hard fujinon electronic video endoscope.
Background technology
Endoscope is to have concentrated traditional optical, ergonomics, precision optical machinery, hyundai electronicses, mathematics, software etc. in one
Detecting instrument, medically using quite varied.It can be entered by small otch or natural cavity sees X ray not in vivo
The lesion that can be shown, and operating theater instruments can be coordinated to carry out visualization operative treatment in vivo.Inside clinically check and can
The endoscope of image clearly is needed to help doctor to improve the accuracy of diagnosis, therefore generally from electronics depending on changing operative treatment
Sight glass.When treating the diseases such as kidney stone, the working sheath of endoscope is needed to vibrate to impact knot while in-vivo image is observed
Stone, percutaneous nephrolithy operation (PCNL) success rate of clinical treatment kidney stone is high at present, and calculus clearance rate is high, but under normal circumstances
For the endoscope working sheath used all in more than 18F, puncturing hole is big to kidney injury greatly, therefore how to design a kind of with small outer
Footpath working sheath while meet that the fujinon electronic video endoscope structure of Treatment need is current problems faced.
The content of the invention
Present invention aim to solve the deficiency of above-mentioned background technology, there is provided and it is a kind of simple in construction, it can avoid intersecting
The disposable hard fujinon electronic video endoscope of infection risk.
In order to achieve this, the disposable hard fujinon electronic video endoscope designed by the present invention, including handle and hard working sheath,
Four-way connection is fixed with the handle, the rear and front end of the four-way connection has a nipple orifice, the hard work
The rear end for making sheath is fixed in the front tab hole of four-way connection, and the rear end of the handle is fixed with feeler lever guide holder, the spy
Bar guide holder, four-way connection and hard working sheath three are coaxial, are fitted close and fix in the rear tab hole of the four-way connection
Have and be coaxial therewith, for ultrasonic feeler lever to be imported to the inner chamber of four-way connection and the reciprocating motion that is brought into close contact with ultrasonic feeler lever surface
Seal receptacle.
Further, the locating ring being coaxial therewith is fixed with the rear end face of the four-way connection, the reciprocating motion is close
Sealing seat includes and the close-fitting small lasso in rear tab hole of four-way connection and the big lasso coaxial with small lasso, the big set
The bottom inside anchor ring of circle is fixedly connected with transition rings, the circumferential bottom margin of the small lasso and the inner circumferential ring of transition rings
Taper ring is fixedly connected between side；The taper ring, transition rings and big lasso form the locating slot coordinated with locating ring.
Specifically, instrument channel, camera passage and illumination passage, the four-way connection are provided with the hard working sheath
Sidepiece be provided with cable connector hole and water supply joint hole, be fixed with minisize pick-up head inside the front end of the camera passage, institute
State minisize pick-up head and be connected with camera cable, the rear end of the camera cable sequentially passes through cable connector hole and handle；Institute
State in illumination passage and be fixed with light source cable, be fixed with light-conductive optic fibre in the light source cable, the rear end of the light source cable according to
It is secondary to pass through cable connector hole, light-conductive joint, light source and handle；Entering of being connected with instrument channel is fixed with the water supply joint hole
Water pipe, the side of the handle are provided with water filling via corresponding with water inlet pipe.
Further, cable guide seat is fixed with the cable connector hole, two lines are provided with the cable guide seat
Cable pilot hole, the light source cable and camera cable are each passed through two cable guide holes.
Further, the handle is provided with the shooting connector being connected with camera cable, described to image in connector
Camera plug is fixed with, full-view camera is fixed with the camera plug.
Further, the handle is formed by being covered on two pieces of mutual cooperation detachable handles with handle lower cover.
The beneficial effects of the invention are as follows：Endoscope structure is simple, easy to use；Avoid medical cross infection；Back and forth
Motion seal seat ensure that the straight reciprocating motion of ultrasonic feeler lever, and the great circle of reciprocating movement sealing seat entangles the apparatus of four-way connection
Hole prevents from flowing out from the water that four-way connection inlet opening is thrown into from instrument hole.When the ultrasonic feeler lever using high rubble rate and clear stone rate
When, ultrasonic feeler lever passes through the ringlet of reciprocating movement sealing seat, and ringlet material is elastic caoutchouc, because reciprocating movement sealing seat is one
Elastic component, the different ultrasonic feeler lever of diameter can closely be waled, make ringlet and ultrasonic feeler lever gapless, prevent leak.Will be reciprocal
The cone circle that the ringlet and great circle of motion seal seat connect is thin-walled rubber, when ultrasonic feeler lever works, drives ringlet freely
The motion of ground high-frequent reciprocating, makes non-resistance in ultrasonic feeler lever vibration processes, and it is disconnected to ensure that ultrasonic feeler lever is not easy to be shaken.Reciprocal fortune
Dynamic sealing seat can accurately import ultrasonic feeler lever in hard sheath, thus can by hard sheath accommodate feeler lever space segment as far as possible do it is small,
So as to reduce the internal diameter of hard sheath, to reduce damage of the puncturing hole to intracorporeal organ.
