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
Technical field

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.
