Description
Technical field
This utility model relates to a kind of operating theater instruments, particularly relates to a kind of portable medical electron mirror.
Background technology
Most section office of this applicable hospital of present fujinon electronic video endoscope use.As department of eye can be made into portable electronic nasopharyngolarygnoscope, for clinical to nasal sinuses, can swallow, the respiratory tract disease such as esophagus checks, Diagnosis and Treat.As checked vocal cords sounding state, to take out in esophagus foreign body etc.Portable electronic bronchoscope is can be made into, for checking gas house steward, bronchus and treat at Pneumology Department.Can be made into electronic cystoscope at Urology Surgery, for checking urethra, prostate, bladder and ureter and treating, as bladder biopsies, insert double J pipe and seal wire etc. to ureter.Endoscope all needs illumination and sterilization.Present endoscope is all generally that the light that cold light source exports guides to endoscope by same about 2 meters of long light guide bundleses, this structure electrical source consumption is large, a cold light source complete machine power comprises bulb power, heat radiation power, Power convert power etc., general general power is at more than 300w, and complex structure cost is high, luminous flux utilization rate is low, the existence of various interface loss, transmission loss, make luminous flux utilization rate less than 3%, and use inconvenience.The light guide bundles of an external diameter 8 ~ 12mm hangs between endoscope and cold light source, makes troubles to operation.In addition, bulb life is not long, easily damages, and general cold light source is all designed with Huan Deng mechanism, requires doctor's self-changeable bulb.If operation runs into bulb malfunction in way, danger can be brought to patient.
Summary of the invention
It is simple that this utility model provides a kind of structure, and the heating of light source is little, good heat dissipation, makes the caliber of endoscope thinner, a kind of portable medical electron mirror of convenient sterilizing; The overall volume solving the electron mirror existed in prior art is large, and illumination caloric value is large, dispels the heat good not, the technical problem of inconvenient immersion sterilization.
Above-mentioned technical problem of the present utility model is solved by following technical proposals: a kind of portable medical electron mirror, comprise operating portion, operating portion is connected with insertion section, one end of operating portion is connected with operating main body, operating main body is connected with display by multicore interface structure is dismountable, the other end of operating portion is connected with insertion section, insertion section is connected with bending section and first end in turn, in operating main body, cold light source is installed, cold light source is connected with light guide bundles by light cone parts, and light guide bundles extends to first end by insertion section.Multicore interface can meet operating main body and is separated fast with display and engages, and can meet the sealing requirements of mirror body, insertion section can be allowed to meet the requirements such as plasma gas sterilization, soaked with liquid sterilization simultaneously.As medical mirror, designer focuses on head end size very much, sometimes in order to reduce 0.1mm head end diameter, often needs Amending design scheme repeatedly.Therefore, the illumination scheme of Portable industrial fujinon electronic video endoscope, inapplicable on medical mirror.As industrial mirror, LED being placed directly in front end, is not merely that head end diameter becomes large problem, and more fatal is that LED heat can make head end temperature raise, and scalds human body mucosal tissue.National Specification, medical mirror inserts any position of human body, and surface temperature must not be greater than 41 DEG C.The present invention adopts small-power, high brightness, light-focusing type LED as light source, is arranged on operating grip inside, hardware heat radiation close to the inner portion.And after adopting the further optically focused of recessed end light cone, by optical transport to optical fibers, guide to endoscope's tip.
As preferably, described light cone parts comprise the metal base plate being positioned at operating portion, and metal base plate is provided with light cone cover, and in light cone cover, be provided with light cone, one end of light cone is connected to LED, and the other end of light cone is connected to light guide bundles.Low-power LED and the large end concave surface of light cone are close to, and after reflective surface outside light cone is assembled, light concentrates on light cone small end, send the light guide bundles be close to and export.Like this, luminous flux loss is little, and efficiency of transmission is high, and unit are intensity of illumination is suitable with high-power cold light source, can meet operation needs.The heat that LED sends, by metal base plate, in transmission of heat by contact mode, passes to the inner original hardware of endoscope handle, finally by handle casing air heat radiation towards periphery.Set up heat balance time about 15 minutes.Because power is little, heat itself is little, and by this natural heat dissipation mode enough, actually to record, after continuous operation 2 hours (reaching thermal equilibrium state already), the temperature rise of endoscopic procedure handle casing is not more than 3 DEG C.
As preferably, described multicore interface structure comprises display stiff end and operating main body stiff end, display stiff end and display one-body molded, operating main body stiff end and operating main body one-body molded, described display stiff end comprises active pointer, operating main body stiff end comprises locking pin, spring is socketed with outside active pointer, locking pin is positioned at the collets of display stiff end, active pointer is positioned at the collets of operating main body stiff end, two insulating surfaces end face laminatings when operating main body is connected with display, locking pin docks with active pointer to be formed and is electrically connected.Active pointer under external force can play up and down, when display is separated with operating main body, active pointer is under spring force effect, its circular arc end face protrudes the about 0.5 ~ 2mm of collets slightly, in conjunction with time, locking pin aligns with active pointer conducting, two collets are bonded to each other, end face keeps concordant, facilitates user's wiping, ensures that gilding does not corrode and is not oxidized.Locking pin glue is installed, and ensures mirror side good seal performance, meets routine disinfection sterilizing requirement.
As preferably, the end of described display stiff end is provided with female thread and forms hold-down nut, and be provided with external screw thread at the plinth of the end of described operating main body, plinth and hold-down nut are connected to be formed and are mechanically connected.Structure is simple, and mounting or dismounting are convenient.
As preferably, the caliber of described insertion section is 3 ~ 8mm, and active length is 100 ~ 800mm.The diameter of the logical optical cross-section of described light guide bundles is 0.2 ~ 3mm, and the power of described cold light source is 0.2 ~ 3w.Traditional cold light source Halogen light, xenon lamp, great power LED etc. do luminous source, and bulb power is at about 40 ~ 200 watts.Be made generally in independent casing, a cold light source complete machine power comprises bulb power, heat radiation power, Power convert consumed power etc., and general general power is more than 300 watts.Cold light source power of the present utility model is low, and heat dissipation capacity is little, loses little.Easy to operate.
Therefore, a kind of portable medical electron mirror of the present utility model possesses following advantage:
By low power LED cold light source as luminous source, caloric value is little, and is mounted in the operating main body of endoscope, and what the caliber of insertion section can be made to do is thinner, good illumination effect, and the overall volume of electron mirror is little.
Multicore interface structure, can realize machinery and electric dual connection, display screen and operating main body separately be carried out disinfection.Machinery engages fast, and docking intensity is high, and multicore electrical engagement, contact resistance is little.
Caliber is thin, and the misery caused patient is little, and little to the infringement of human body natural's tract mucosal tissue, patient's post-operative recovery is fast.
