Abstract

The invention discloses a disposable hard electronic endoscope which comprises a handle and a hard working sheath, wherein a four-way joint is fixed in the handle; a joint hole is formed in each of the front and rear ends of the four-way joint; the rear end of the hard working sheath is fixed in the joint hole in the front end of the four-way joint; a probe guide seat is fixed at the rear end of the handle; the probe guide seat, the four-way joint and the hard working sheath are coaxial; and a reciprocating motion sealing seat which is coaxial with the four-way joint, is used for guiding an ultrasonic probe into an inner cavity of the four-way joint and is in close fit with the surface of the ultrasonic probe is fixed in the joint hole in the rear end of the four-way joint in a close fit manner. The endoscope is simple in structure and convenient to use; a large ring of the reciprocating motion sealing seat sleeves a mechanical hole of the four-way joint to prevent water pumped from a water inlet hole of the four-way joint from flowing out from the mechanical hole; the reciprocating motion sealing seat accurately guides the ultrasonic probe into the hard sheath, so that the space part for accommodating the probe in the hard sheath can be made small as much as possible; and therefore, the inner diameter of the hard sheath is decreased, and damage of a puncture hole to organs in a body is reduced.

Description

A kind of disposable hard fujinon electronic video endoscope
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, human engineering, precision optical machinery, hyundai electronicses, mathematics, software etc. in one Detecting instrument, quite varied medically applying.It can be entered by little otch or natural cavity sees X-ray not in vivo The pathological changes that can show, and operating theater instruments can be coordinated to carry out in vivo visualizing operative treatment.Internal inspection clinically and can Need the endoscope of image clearly to help doctor to improve the accuracy of diagnosis depending on changing operative treatment, therefore generally select in electronics Sight glass.When treating the diseases such as renal calculuss, the working sheath of endoscope is needed to vibrate to impact knot while observing in-vivo image Stone, PCN operation (PCNL) success rate of current clinical treatment renal calculuss is high, and calculus clearance rate is high, but under normal circumstances , all in more than 18F, puncturing hole is big to kidney injury greatly for the endoscope's working sheath using, and therefore how to design one kind and has outside small Footpath working sheath, the fujinon electronic video endoscope structure simultaneously meeting Treatment need are current problems faced.
Content of the invention
Present invention aim to solving the deficiency of above-mentioned background technology, providing a kind of structure simple, can avoid intersecting The disposable hard fujinon electronic video endoscope of infection risk.
For realizing this purpose, disposable hard fujinon electronic video endoscope designed by the present invention, including handle and hard working sheath, It is fixed with four-way connection, the rear and front end of described four-way connection has a nipple orifice, described hard work in described handle The front tab in the hole of four-way connection is fixed in the rear end making sheath, and the rear end of described handle is fixed with feeler lever guide holder, described spy Bar guide holder, four-way connection and hard working sheath three are coaxial, and the rear tab in the hole of described four-way connection is fitted close fixes Have be coaxial therewith, the reciprocating motion for ultrasonic feeler lever being imported the inner chamber of four-way connection and fit tightly with ultrasonic feeler lever surface Seal receptacle.
Further, the rear end face of described four-way connection is fixed with the locating ring being coaxial therewith, described reciprocating motion is close Envelope seat includes close-fitting little lasso and the big lasso coaxial with little lasso, described big set with the rear tab hole of four-way connection The bottom inside anchor ring of circle is fixedly connected with transition rings, the circumferential bottom margin of described little lasso and the inner circumferential ring of transition rings It is fixedly connected with taper ring between side;Described taper ring, transition rings and big lasso form the locating slot with locating ring cooperation.
Specifically, described hard work intrathecal is provided with instrument channel, photographic head passage and illumination channel, described four-way connection Sidepiece have cable connector hole and water supply joint hole, be fixed with minisize pick-up head inside the front end of described photographic head passage, institute State minisize pick-up head and be connected with photographic head cable, the rear end of described photographic head cable sequentially passes through cable connector hole and handle;Institute State and in illumination channel, be fixed with light source cable, in described light source cable, be fixed with light-conductive optic fibre, the rear end of described light source cable according to Secondary through cable connector hole, light-conductive joint, light source and handle;Described water supply joint in the hole is fixed with entering of connecting with instrument channel Water pipe, the side of described handle has water filling via corresponding with water inlet pipe.
Further, it is fixed with cable guide seat at described cable connector hole, described cable guide seat has two lines Cable pilot hole, described light source cable and photographic head cable are each passed through two cable guide holes.
Further, described handle is provided with the shooting connector being connected with photographic head cable, in described shooting connector It is fixed with photographic head plug, described photographic head plug is fixed with full-view camera.
Further, described handle is made up of lid and handle lower cover on two pieces of detachable handles that cooperate.
The invention has the beneficial effects 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 the water thrown into from four-way connection inlet opening from flowing out 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 gum elastic, because reciprocating movement sealing seat is one Ultrasonic feeler levers different for diameter can closely be waled by elastic component, make ringlet and ultrasonic feeler lever gapless, prevent leak.Will be reciprocal The cone circle that the ringlet of motion seal seat and great circle connect is thin-walled rubber, when ultrasonic feeler lever works, drives ringlet freely Ground high-frequent reciprocating motion, makes non-resistance in ultrasonic feeler lever vibration processes, and it is disconnected to ensure that ultrasonic feeler lever is difficult to be shaken.Reciprocal fortune Dynamic sealing seat can accurately import ultrasonic feeler lever in hard sheath, therefore can do the space segment accommodating feeler lever in hard sheath little as far as possible, Thus reducing the internal diameter of hard sheath, to reduce the damage to intracorporeal organ for the puncturing hole.
