Description

Can bent endoscope

This utility model relates to medical apparatus and instruments, especially the upper respiratory tract surgical medical equipment.

When making tracheal intubation, often adopt following instrument at present, the one, the intubate laryngoscope, this laryngoscope is difficult to observe glottis, in order to see glottis clearly, often uses force sometimes, easily make patient's odontoseisis, fracture or come off, the tooth that comes off is fallen into air flue easily, causes and stops up trouble.The 2nd, the branchofiberoscope induction and tracheal intubation, this equipment is very expensive, in addition since the patient can swallow and be in the active state branchofiberoscope and will enter glottis certain difficulty is arranged.

The purpose of this utility model is a kind of flexible endoscope of design, directly inserts throat and observes throat and glottis, need not violence, also can utilize it that local infiltration anesthesia, minor operation and suction expectorant etc. are carried out in the position that can not look at straight.

This utility model is to realize like this, in a gum sleeve, place lens barrel, sputum aspirator tube passage, local anaesthesia (or slotting tool) tube passage, lens barrel is to be formed by connecting by some mirror sections, the mirror section is a trapezium structure, upper base is short eyeglass, go to the bottom and be long eyeglass, side is a support plate, short eyeglass and long eyeglass are installed in opposite directions, the long eyeglass of mirror section is coupled together with active coupling, in the middle of short eyeglass one side, backguy is installed, allow backguy run through all mirror sections, the effect of backguy is the flexibility of regulating lens barrel, on the distal edge of lens barrel electric light source is housed.

One end of gum sleeve is equipped with wide-angle lens, wide-angle lens is installed in the wide-angle lens, wide-angle lens is installed the seesaw shower nozzle outward, the seesaw shower nozzle can play anesthesia and fixing can the pharynx, outlet of local anaesthesia tube passage and sputum aspirator tube channel outlet are arranged on the wide-angle lens, scraper plate is housed on the wide-angle lens, scraper plate cleans wide-angle lens, scraper plate can drive or spur with line with micro machine, the other end of gum sleeve is installed enlarging lens, magnifier is installed in the enlarging lens, on enlarging lens, open the backguy hole, local anaesthesia tube passage inlet, wire hole, the sputum aspirator tube feeder connection, scrape the printed line hole, gum sleeve leans on the outside cover one of magnifier head end to have the metal canula of bush support, and metal canula overcoat cushion has handle hole and places battery case on the bush support.

Gum sleeve of the present utility model and lens barrel are bendable structure, regulating its flexibility with backguy can be easily reach light source and lens barrel and can not look at the position straight, the scene of far-end passes to the magnifier of near-end by the reflection of eyeglass in the lens barrel, when observing, can implement local anaesthesia art and slotting tool operation by the local anaesthesia tube passage, with expectorant or dope sucking-off, carry out other operations such as tracheal intubation by the sputum aspirator tube passage by handle hole.

The example of contrast accompanying drawing is further described below:

Accompanying drawing 1 can bent endoscope outline drawing

Accompanying drawing 2 lens barrel structure figure

Accompanying drawing 3 scraper plate schematic diagrams

In a gum sleeve 12, place lens barrel (structure as shown in Figure 2), sputum aspirator tube passage, local anaesthesia tube passage, lens barrel is formed by connecting by some (this example is 5) mirror sections, the mirror section is a trapezium structure, upper base is short eyeglass 3, go to the bottom and be long eyeglass 1, side is a support plate 2, short eyeglass 3 and long eyeglass 1 are installed in opposite directions, the long eyeglass 1 usefulness active coupling 5 of mirror section is coupled together, one backguy 4 is installed in the middle of short eyeglass one side of lens barrel runs through all mirror sections, electric light source 7 is installed on the distal edge of lens barrel, electric light source 7 is connected with the mains with electric wire 6.

One end of gum sleeve 12 is equipped with wide-angle lens 13, seesaw shower nozzle 14 is installed in wide-angle lens 13 outsides, wide-angle lens 27 is installed in the wide-angle lens 13, tube passage outlet 15 of beginning fiber crops and sputum aspirator tube channel outlet 16 on the wide-angle lens 13, the other end of gum sleeve 12 is installed enlarging lens 22, magnifier 28 is installed in the enlarging lens 22, on enlarging lens 22, open backguy hole 17, local anaesthesia tube passage inlet 18, power line hole 19, sputum aspirator tube feeder connection 20 and scrape printed line hole 23, gum sleeve 12 is by the metal canula 11 of a band of the outside cover bush support 8 of enlarging lens 22 ends, metal canula 11 overcoat cushions 10, have handle hole 9 on the bush support 8 and place battery case 21, the backguy 4 of lens barrel is drawn from backguy hole 17, and electric wire 6 is drawn and received on the battery case 21 from wire hole 19.One backguy scraper plate (as shown in Figure 3) is installed on the wide-angle lens 13, be used for wide-angle lens 27 is cleaned, clear to guarantee observation, the backguy scraper plate is formed by scraping flat spring 24, scraper plate 25 and scraper plate backguy 26, and scraper plate backguy 26 is drawn from scraping printed line hole 23 by gum sleeve 12.

During use, flexibility with backguy 4 adjusting gum sleeves 12, and will extend into the position that to observe with an end of wide-angle lens 13, the scene of far-end passes to near-end by the reflection of long eyeglass 1 and short eyeglass 3 in the lens barrel and can be clear that from magnifier 28, at this moment if look-out station is implemented local anesthesia or operation, can penetrate anesthesia bobbin or slotting tool from local anaesthesia tube passage inlet 18, at this moment if expectorant or other dope of look-out station are removed, can penetrate sputum aspirator tube with expectorant or dope sucking-off from sputum aspirator tube feeder connection 20, operating period is made dirty as wide-angle lens 27, can spur scraper plate backguy 26 scraper plate 25 move left and right are scraped off dirt.

Also can earlier the anesthesia pipe be installed in the local anaesthesia tube passage and with anesthetic needle and be fixed on the seesaw shower nozzle 14, sputum aspirator tube is installed in the sputum aspirator tube passage and will inhales the expectorant end be fixed on the sputum aspirator tube channel outlet 16, gum sleeve 12 is stretched into want look-out station (simultaneously with backguy 4 adjusting flexibility) again.

After gum sleeve is extend into correct position, can allow the patient sting on the tight metal-coating tube cushion to help the location, more help operation.Can stretch into other instrument simultaneously from handle hole 9 and carry out operations such as tracheal intubation.
