Description

Medical oral cavity dilator with illuminating lamp

Technical field

This utility model relates to the medical apparatus and instruments that a kind of dental operation is used, and is a kind of Medical oral cavity dilator with illuminating lamp specifically.

Background technology

In operation on oral cavity and inspection, for ease of operation, need patient's mouth open up into a certain degree and keep the regular hour.Chinese patent 2010101762485 discloses a kind of < < integral-type initiative oral cavity mouth gag > >, another Chinese patent 2010101758935 discloses a kind of < < splitting active oral cavity mouth gag > >, both between maxillary plate and mandibular plate, torsion spring is set, utilizes the torsion of torsion spring to make maxillary plate and mandibular plate keep the strength necessarily expanding outwardly.During use, doctor or patient pinch maxillary plate and mandibular plate is put between the upper and lower facies occlusalis dentis in patient oral cavity, and after unclamping hands, the torsion of torsion spring is by patient's oral cavity expanding.Although this oral cavity mouth gag is easy to use, and can do the motion of independently remaining silent according to patient's wish, owing to having adopted two groups of torsion springs, lay respectively at the both sides of jaw plate, complex structure, has blocked the sight line of patient's mouth side, does not utilize operation technique; In addition, owing to there is no illuminator, more inconvenient in operation technique.

Summary of the invention

The purpose of this utility model is to provide the Medical oral cavity dilator with illuminating lamp of a kind of compact conformation, easy to use, convenient operation observation.

For reaching above object, the technical scheme that this utility model adopts is: should comprise the Lower jaw support that is sleeved on lower jaw tooth, be sleeved on the upper jaw holder on maxillary teeth with Medical oral cavity dilator of illuminating lamp, described Lower jaw support and upper jaw holder are the shape of a hoof, described Lower jaw support and upper jaw holder are hinged on respectively the two ends of torsion spring, in described Lower jaw support and upper jaw holder, be respectively equipped with ball-and-socket, in described ball-and-socket, coordinate spherical shell is installed, in the inner chamber of described spherical shell, illuminating lamp is installed, described illuminating lamp is electrically connected to the battery in the holder of embedding jaw by wire and power supply circuits; On described spherical shell, be fixedly connected with the conduit that is communicated with its inner chamber.

The two ends of described torsion spring are connected spiral and lower spiral by upper connecting rod respectively with lower link, described upper spiral and lower spiral are all the serpentine pipes that adopt elastomeric monofilaments to be coiled to form, upper spiral and lower spiral are arranged on respectively in the installing hole on upper jaw holder and Lower jaw support, and the end of described upper spiral and lower spiral is equipped with the stiff end embedding in jaw holder.

The beneficial effects of the utility model are: compact conformation, and easy to use, torsion spring is positioned in the middle of jaw holder, does not affect operation sight line, and the more convenient operation of illuminating lamp that carries capable of regulating direction of illumination is observed.

Fig. 1 is the structural representation of an embodiment of this utility model.

Fig. 2 is the plan structure schematic diagram of Fig. 1 embodiment.

The specific embodiment

As shown in Figure 1, Medical oral cavity dilator with illuminating lamp described in the utility model comprises the Lower jaw support 1 that is sleeved on lower jaw tooth, is sleeved on the upper jaw holder 2 on maxillary teeth, described Lower jaw support 1 is the shape of a hoof with upper jaw holder 2, is set on mandibular teeth and maxillary teeth during use.Described Lower jaw support 1 and upper jaw holder 2 are hinged on respectively the two ends of torsion spring 3, the state that the torsion of torsion spring 3 is kept away from two jaw holders, but two jaw holders can be pressed together with hand, be convenient to install in oral cavity.

As shown in Figure 1, Figure 3, in described Lower jaw support 1 and upper jaw holder 2, be respectively equipped with ball-and-socket, in described ball-and-socket, coordinate spherical shell 4 is installed, illuminating lamp 5 is installed in the inner chamber of described spherical shell 4, described illuminating lamp 5 is electrically connected to the battery 6 in the holder of embedding jaw by wire and power supply circuits; On described spherical shell 4, be fixedly connected with the conduit 41 that is communicated with its inner chamber.Conduit 41 can guiding illumination lamp 5 light point to specific direction, conduit 41 is also for spherical shell 4 rotates, swings the handle that the application of force is provided in ball-and-socket simultaneously, when need to change direction of illumination, can promote conduit 41 by operating theater instruments, make its deflection certain orientation.

As shown in Figure 1 and Figure 2, the two ends of described torsion spring 3 are connected spiral 33 and lower spiral 34 by upper connecting rod 31 respectively with lower link 32, described upper spiral 33 and lower spiral 34 are all the serpentine pipes that adopt elastomeric monofilaments to be coiled to form, upper spiral 33 and lower spiral 34 are arranged on respectively in the installing hole on upper jaw holder 2 and Lower jaw support 1, and the end of described upper spiral 33 and lower spiral 34 is equipped with the stiff end 35,36 embedding in jaw holder.Elasticity goes up the effect that spiral 33 and lower spiral 34 are born respectively the hinge between jaw holder and connecting rod preferably, except allowing circumferencial direction swings, can also to allow suitable swinging, avoids being subject to force unbalance to cause discomfort because of jaw holder both sides.

During use, patient or doctor pinch Lower jaw support 1 and upper jaw holder 2 with hands, send in patient's mouth, after unclamping hands, Lower jaw support 1 and upper jaw holder 2 natural separation, by patient's oral cavity expanding, the radiation direction of adjusting illuminating lamp 5 illuminates operative site and can carry out examination of mouth or operation.
