Abstract
A medical self-focusing endoscope features that the optical fibre rod is used as image relay lens to simplify the structure of imaging tube, so reducing the diameter of endoscope and the bending of image rod makes the observation of observation window a certain angle to ensure the straight line of working channel to stretch out.
Description
This utility model belongs to the improvement of clinical operation with the self-focusing endoscope structure, relates to optical instrument manufacturing technology field.
At present, the endoscope that the neurosurgery clinical operation is used adopts conventional optical glass to constitute, and its complex structure makes that the sight glass diameter is thicker, is generally about 10mm, and the damage that causes in operation is bigger, and the recovery of adversary's postoperative body has certain influence; Again because the axis of sight glass inner vision tube passage and service aisle is parallel, make the inconvenient operation of operation, make the eyepiece end can not be crooked and look in the tube passage the conventional eyeglass that is provided with, this just forces the terminal bending of service aisle just can be convenient to operation, make the turnover of some operating theater instruments in service aisle just seem inconvenient like this, especially unyielding apparatus also just can not use; Use this sight glass when cranium is opened in operation, must adopt puncture needle to add the method for sheath cover, and in operation, keep the sheath cover, not only make operation technique inconvenience, also make the operating time lengthening.
The purpose of this utility model is to design a kind of medical self-focusing endoscope, to overcome the above-mentioned defective that exists.
The designed medical self-focusing endoscope of this utility model realizes in the following manner, it is made up of sight glass and mirror holder, eyepiece and mirror holder and cold light source system three parts of throwing light on, wherein sight glass is to be provided with imaging to look pipe, service aisle and lighting fiber in the sight glass sheath, at the terminal fixture sight glass of sight glass sheath mirror holder, mirror holder is provided with the lighting source interface, and the end of mirror holder is provided with the service aisle hold-down support; Eyepiece is in the eyepiece mirror holder eyepiece group to be set and to constitute; Luminous source system is to pick out the front end that optical fiber cable is delivered to illumination light by light source interface sight glass at the cold light source case; It is characterized in that, in the sight glass sheath, be provided with imaging and look the lighting fiber that scatter pipe, service aisle, waterflood path and gap, the sight glass front end is hemispherical structure, it is the self-focusing image-forming objective lens that the pipe front end is looked in described imaging, be close to object lens with the fibre optic image transmission rod as relay lens, the end that passes the picture rod stretches out and is 35 ° of-50 ° of bendings behind the sheath and is stretched out by the sight glass mirror holder; The terminal service aisle hold-down support that is provided with of sight glass mirror holder can make the service aisle straight line stretch out, and is set with waterflood path interface bearing on the sight glass mirror holder; Stretch out the place in the biography of sight glass mirror holder as rod and be set with eyepiece mirror holder holder, and the eyepiece mirror holder is inserted in pass the picture rod and can fixedly mounts thereon.
Because this utility model adopts optical fibre rod as passing as relay lens, makes imaging look the designs simplification of pipe, can not only dwindle the diameter of sight glass, and pass the terminal bending of picture rod and make the observation of observation window be certain angle, thereby the straight line that has guaranteed service aisle stretches out; Use this utility model after opening the cranium puncture, because of this sight glass termination is hemispherical, then need not the sheath cover and can directly insert intracranial, throw light on cold light source, image images in the self-focusing object lens in the body, again through fibre optic image transmission rod to the eyepiece group, its imaging can be spied on and not influence the operation of service aisle after amplifying by observation window; As can be seen, this utility model makes the operation of operation become simple and convenient, and it more meets the microinvasion principle of following in the neurosurgical treatment, also is beneficial to the recovery of patients after surgery body.It has the advantage that diameter is little, easy and simple to handle, simple in structure, cost of manufacture is low.
Accompanying drawing 1 is the structural representation of the designed endoscope of this utility model, and accompanying drawing 2 is the end view of sight glass among Fig. 1; 1 is the hemispherical termination of sight glass among the figure, and 2 are the self-focusing image-forming objective lens, and 3 is fibre optic image transmission rod (relay lens), 4 is the sight glass mirror holder, and 5 is the cold light source interface, and 6 is waterflood path interface bearing, 7 is the service aisle hold-down support, 8 is eyepiece mirror holder holder, and 9 is the eyepiece group, and 10 is the eyepiece mirror holder, 11 is service aisle, 12 look pipe for imaging, and 13 is lighting fiber, and 14 is waterflood path.
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
Referring to accompanying drawing, the designed medical self-focusing endoscope of this utility model is made up of sight glass and mirror holder, eyepiece and mirror holder and illumination cold light source system three parts, its assembling sequence is, earlier pipe being looked in service aisle, waterflood path and imaging is respectively charged in the sight glass sheath, look the pipe front end in imaging and insert the self-focusing image-forming objective lens, look the pipe rear end from imaging and insert the fibre optic image transmission rod, and will pass the terminal roasting soft bending of picture rod, preferably be 45, it is stretched out from the sight glass mirror holder; Again the gap of lighting fiber from the sight glass sheath inserted, stretch out by light source interface place on the sight glass mirror holder, connect waterflood path and interface bearing thereof, connect service aisle and hold-down support thereof again, cementation sight glass sheath is connected with the sight glass mirror holder, waterflood path interface bearing and service aisle hold-down support is fixedly installed again; Satisfactory light source interface is processed at the light source interface place, eyepiece mirror holder holder is inserted in biography to be bonded on the sight glass mirror holder as rod, can itself and sight glass mirror holder and passage bearing fixedly be connected as a single entity with screw, to pass again as rod and be inserted in eyepiece mirror holder front end, and the eyepiece mirror holder is spirally connected is fixed on the eyepiece mirror holder holder.Sight glass termination hemispherical can adopt the way of resin dropping point to make, and reserves each passage unimpeded; Also can adopt the bonding way of glass hemisphere to make, make the hole of each passage in advance; The way that also can adopt the rustless steel suitcase to connect is made, and because of stainless light tight, this method also need precast the duct of each lighting fiber except that the hole that is reserved with each passage; So can finish making.
The inventor makes endoscope's sample by above-mentioned requirements, and its parameter is as follows: sight glass diameter 5mm, service aisle diameter 2.1mm, pipe diameter 1.4mm is looked in imaging, waterflood path diameter 1.2mm, lighting fiber diameter 0.9mm, crooked 35 ° of eyepiece and mirror body axis direction.The optical parametric of camera lens is: the angle of visual field＞70 °, image-forming range 0.5-20mm, imaging resolution＜200 pair lines per millimeter.Fine through clinical trial result.
