Abstract
The present invention relates to a medical three-dimensional endoscope which is characterized in that the medical three-dimensional endoscope comprises two lenses, wherein through a soft image rod, the back part of each of the lenses is connected with an eye lens, the head parts of the lenses can be separated and can also be combined together, the outer parts of two soft image rods are coated with hoses, and the back parts of cold light sources are connected with optical fiber of which the periphery is arranged in the directions of the lenses in the hoses through the soft image rods. The back part of each of the eye lenses is connected with an image made into a television format by a television camera, and the back part of each of the television cameras is connected with one or a plurality of LCD visual television glasses. The present invention can provide a feeling like that left and right eyes are used for observing destination workspaces to users, the distance perception exists, and the stereo perception is strong. When the users observe, the angle is favorable, and tiredness is not easy to generate if the present invention is used for a long time.
Description
The present invention relates to a kind of medical endoscope.
Medical endoscope comprises peritoneoscope, thoracoscope, arthroscope etc., is the surgical operation apparatus, and by endoscopic surgery, it is little to have wound, and patient recovers advantage such as fast, so apply extremely rapid in the whole world.But because present endoscope is two dimensional image, can not show stereo image, have following shortcoming in the use:
(1) no third dimension does not have distance perspective to target organ.Operator reach custom by rule of thumb and estimate its distance, and this is very inaccurate.More be difficult to grasp the not too abundant or abecedarian for experience, so often owing to misoperation causes complication, do not clamp fully as blood vessel and to produce hemorrhagely, bile duct is not clamped fully and is produced bile and outflow biliary peritonitis etc.Many for this reason hospitals are only fixing by one or several doctor's operation that is rich in operating experience, and like this, this doctor does not exist, and then can't use.
(2) because the doctor sees is TV monitor, it is placed in the some places of operating room, and eyes were seen to a direction, an angle when doctor operated, the long fatigue that is easy to generate of time.More not good for the doctor that cervical spondylosis is arranged.In addition, the assistant is arranged when operating on, monitor is usually over against operating doctor, and is then very poor for the assistant visual angle, and the assistant sees uncomfortablely especially.
Purpose of the present invention is exactly can show stereo-picture in order to overcome the shortcoming that present medical endoscope can not show stereo-picture, to provide a kind of, exist distance perspective, doctor to see the three-dimensional medical endoscope of no sticky feeling for a long time.
The present invention realizes like this.Structure of the present invention is:
1, twin-lens bracing type stereo endoscope, its structure are two camera lenses, and each camera lens is all by connecing an eyepiece behind the soft image rod, the camera lens head can separate, and also may be incorporated in together, during into and out of splanchnocoel, be in closed condition, enter the purpose working area, change into out state.Two soft image rods are outer to be connected on the optical fiber of arranging to lens direction in the flexible pipe by flexible pipe parcel around soft image rod before one cold light source, make cold light source pass through the optical fiber direct irradiation to Target organ.Connect television camera behind each eyepiece and take the photograph into the image of TV format.
The present invention can install a shelf or a clip on flexible pipe, this shelf frame on the operation table or this clip by the shelf frame on operation table.
The head of camera lens of the present invention can pass through the mutual repulsion of the identical polar of electric magnet, makes and separates when entering the purpose working area; On also can the soft image rod between two camera lenses or horizontal screw is installed after the camera lens by turning separately two camera lenses of screw.
Two camera lenses of the present invention are installed in the inboard of soft image rod, make camera lens separately after, two camera lenses are seen to same Target organ.
2, the visual Television glasses of liquid crystal display is the commercially available prod, and its eyes are two television screens.The television camera output that the signal of each television screen connects after by eyepiece.Can connect one or several glasses behind each video camera, use jointly for operator person and assistant.
The present invention is owing to there are two camera lenses that separate to observe the purpose working area, and respectively signal transferred on each television screen of the visual Television glasses of liquid crystal display, observes the purpose working area for people's the similar people's images of left and right eyes of feeling, has distance perspective, and third dimension is strong.And angle was good when the doctor observed, and long-time the use is difficult for producing fatigue.
The present invention also can adopt the image-forming principle of stereoscopic television, connect television camera behind each eyepiece, the light angle of the shooting of two video cameras is vertical each other, imaging on same stereoscopic display screen jointly, adopt the glasses (being that left eyeglass lens is vertical each other with the light that the right eye eyeglass enters) of polarized light to observe display screen, what each user was seen all is stereoeffect, in order to replace the visual Television glasses of liquid crystal display.
The invention will be further described below in conjunction with drawings and Examples.
Embodiment 1:
Fig. 1 is an open mode sketch map of the present invention;
Fig. 2 is the present invention's view of closing.
Among the figure, (1) camera lens, (2) soft image rod, (3) flexible pipe, (4) optical fiber, (5) cold light source, (6) eyepiece, (7) television camera, the visual Television glasses of (8) liquid crystal display, (9) are screw laterally, (10) lens cap, (11) target organ pipe.
As shown in Figure 2, camera lens (1) is in turnover during splanchnocoel, lens cap (10) Gai Zaijing On the head, camera lens (1) is in closure state. Each camera lens (1) is all by soft image rod (2) After connect an eyepiece (6), two soft image rods (2) are outer by a flexible pipe (3) parcel, one is cold Light source (5) by optical fiber (4) in flexible pipe (3) soft image rod (2) all around to camera lens The direction irradiation. Connect television camera (7) behind each eyepiece (6), after to connect liquid crystal display visual Television glasses (8) is for showing. As shown in Figure 1, enter the purpose workspace after, turn screw (9), two camera lenses (1) separate, and lens cap (10) can be installed on thereafter by pressing Such as the controller opens on the soft image rod (2). Controller can adopt Electromagnetic Control or machinery Control. Open cold light source (5) and television camera (7), the visual Television glasses of liquid crystal display (8) the upper form that gets final product display-object organ (11) is for doctor's operation.
The diameter of two camera lenses of the present invention is 3～5 millimeters.
Embodiment 2:
The accompanying drawing of present embodiment is similar to embodiment 1, but with commercially available need not power supply and the polarised light glasses of holding wire replace the visual Television glasses of liquid crystal display (8), connect stereoscopic display screen behind two video cameras, this display screen receives the signal of two video cameras from two orthogonal angles, and demonstrates simultaneously.
