Abstract

The utility model provides a line operating device for the rotary peep of an endoscope probe, which aims at the phenomena that the probe is wobbled and rotated intermittently, the tail part rotates, but the head part does not rotate or the tap part does not rotate, but the head part continues to rotate, which are difficultly controlled due to resistance and twist in the prior endoscope of which the front end probe is driven by the rotation of the tail part to rotate, in addition, the line operating also solves the problems of complicated technology, accurate manufacture, high manufacture cost, difficult popularization and large size of a probe micro motor. The device comprises a rotor, two operating line fixed points, a stator arranged on the surface of the rotor, a penetrating hole which is arranged on the stator and penetrates through the stator, and an operating line, wherein the operating line fixed point on the rotor is connected with operating lines back to each other; the operating lines penetrate through the stator from the penetrating hole on the stator; and the rotor is circularly rotated in the stator by line operation. Because of simple structure, eyeshot enlarging function of a rotary probe, low cost of materials and whole manufacture, the utility model provides a new popular manufacture method and a use field for rotary endoscope for disposable medical treatment.

Description

A kind of line manipulation device that the endoscope probe rotation is spied on

Technical field

This utility model relates to a kind of device that the endoscope probe rotation is spied on, and specifically, is the device that makes the endoscope head rotation by the control wire tractive.

Background technology

Endoscope is the product of modern high technology.It can be deep in slit that the people is invisible to the naked eye, the tubule sees its inner situation clearly.In field extensive uses such as industry, science and technology and medical diagnosis and treatment.But no matter be using visible light, the infrared or endoscope of ultrasonic technique, because the limitation of its field-of-view angle has hindered in wider use.For this reason, people have invented the afterbody rotation with endoscope, and the method that drives the head rotation enlarges the angle of spying on.Such as, in blood vessel, in the intervene operation, observe the blood vessel wall situation of pathological changes all around with this method.But the afterbody rotation has its shortcoming, because of moment of torsion oversize (usually more than one meter), adds vascular bending, owing to the resistance incarceration, head is not changeed in the time of can causing the afterbody rotation; Or because of afterbody continues rotation, to torsion during greater than resistance, the torsion of accumulation discharged quickly in the past, and made head suddenly the commentaries on classics or at the uniform velocity unsettled phenomenons such as redirect, shake not occur more.In order to overcome these deficiencies, people have invented miniature rotation motor again, are loaded on probe portion, make it can stablize rotation evenly.But the complex manufacturing technology of micromotor, precision have hindered it and have done more tinyly.Now the thinnest blood vessel endoscope mirror diameter is below 1 millimeter, and micromotor adopts present manufacturing process not accomplish so tiny.In addition, involving great expense of micromotor do not possess on a large scale, popularizes once the condition of using.

Summary of the invention

This utility model promptly by the tractive control of control wire, makes the probe back and forth rotation back and forth indiscriminately ad. as one wishes of endoscope head at the above not enough device that adopts a kind of easy cheapness, perhaps forwards transfixion ground, a certain position to and observes.Thereby spy on for endoscope probe rotation and to broaden one's vision, especially on the expansion application of the popular disposable intervention endoscope that medical diagnosis and treatment are used, provide a new scheme.

In order to achieve the above object, this utility model has adopted following technical scheme:

Adorn a turning cylinder at the back location of endoscope probe, link to each other, can drive the probe rotation during rotation with probe.Control wire is wound in turning cylinder or it is extracted out from turning cylinder, make its rectilinear motion become axial rotation and drive probe and do the circumference rotation.So just can do rotation with line manipulation front-end probe in the endoscope rear end spies on.

Be specially: be nested with two-layer sleeve pipe, skin is a stator, maintains static.Nexine is the turning cylinder that rotor is promptly twined or extracts out by control wire.There is the lamellar spacing centre that stator and rotor are nested, and rotor can rotate in the stator sleeve pipe.A, B two control wires twine rotor from opposing both direction respectively from the clearance layer that stator and rotor are pierced in the hole that passes of stator, and end points is fixed on the rotor.Because direction is opposing, when extracting control wire A out, drive rotor towards extracting the direction rotation out, the control wire B of opposing direction is oppositely twined into.How many control wire A extracts out, and how many control wire B oppositely twined into, otherwise too.Like this, a line is extracted a reverse wire-wound out and is advanced, and again and again, the nexine rotor is just done circumference and come and gone rotation in the sleeve pipe of outer stator.

Can on stator, only open one and pass the hole, two control wires are pierced into from same hole.For fear of phase mutual friction and interference, two control wires can be opened on diverse location in the hole that passes on the stator, as straight line tandem or horizontal line and non-horizontal line dislocation arrangement up and down.Pass the hole not on same horizontal line or be not same hole as two control wires on the stator, as straight line tandem or non-horizontal line dislocation arrangement about being, then the fixing point of two control wires must corresponding with it respectively stator passes the hole and is positioned at same level on the rotor, avoids shaking up and down when line causes rotation because of taking out on the varying level line.Pass the hole on same horizontal line the time when what two control wires entered stator, two control wires can opposingly be fastened on same fixing point or same horizontal two different fixing points on the rotor.When two control wires enter stator to pass the hole be not with the hole or straight line tandem and epitrochanterian fixing point are not with point or up and down during the straight line tandem up and down, the angle that can form the rotor rotation be greater than or less than pass the hole be with the hole or up and down straight line tandem and epitrochanterian fixing point be with point or the angle of rotor rotation during the straight line tandem up and down, so can be according to need setting two control wires of reality the position that passes hole and rotor fixing point at stator.

Control wire is tractive by hand, also can external motor elevator, or by computer instruction motor elevator.

Outside the fujinon electronic video endoscope entities such as that the nexine rotor can be enclosed within is ultrasonic, infrared, CCD.When rotor rotates, drive endoscope's entity and rotate together.Also can be at the pre-installed one side of the probe of fibre opic endoscope inclination angle reflecting mirror, rotor is connected on the reflecting mirror.When rotor rotation, endoscope's entity is motionless, and reflecting mirror rotates with rotor, and the situation of sidewall around the reflection passes to the back by optical fiber again and observes.

The sleeve pipe that nexine is made rotor also can omit, and the fixing point of A, B two control wires directly is fixed on the entity of endoscope head section as rotor, can save the thickness of rotor sleeve like this, does integral body thinner.

The beneficial effects of the utility model are, line method of operating with easy cheapness, make endoscope probe can the circumference range internal rotation spy on, enlarged the visual field of endoscope, and on the expansion application of the popular disposable intervention endoscope that uses for medical diagnosis and treatment, provide a new scheme.
