Description

Oral cavity needle

Technical Field

The utility model belongs to the field of medical equipment, in particular to oral needle.

Background

The oral cavity is an intraoral cavity and comprises two lips, two cheeks, a hard palate, a soft palate and the like; the oral cavity has organs such as teeth, tongue, salivary gland, etc. The oral diseases include halitosis, toothache, caries, oral ulcer powder, and skin flap repair.

The oral cavity needle is a common medical instrument for treating oral cavity diseases, and comprises a needle head and a handle, wherein the handle and the needle head are integrally formed, and the handle is thick and mainly bears the force of the needle head during working. Therefore, after the oral cavity needle is used for a period of time, the needle head is easily passivated or damaged, and then the whole oral cavity needle cannot be used, so that the oral cavity needle is easily wasted.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an oral cavity needle to reduce the waste of oral cavity needle handle.

An oral cavity needle in this scheme, includes handle and syringe needle, is equipped with two on the handle and is used for threaded connection the screw hole of syringe needle, two screw hole mutually perpendicular just is close to each other, one of them the screw hole is located the one end of handle, another the screw hole is located the lateral wall of handle.

The working principle and the beneficial effects of the scheme are as follows: when in use, the needle head is in threaded connection with the handle to be normally used, and the needle head can be replaced when damaged; the problem that the whole oral cavity needle cannot be used is avoided. In addition, in the use process, the handle and the needle head are required to be kept in a straight line sometimes and are required to be kept perpendicular sometimes, and the needle head is in threaded connection with the threaded hole at the end part of the handle when the handle and the needle head are required to be kept in a straight line by arranging two threaded holes which are perpendicular and close to each other; when the handle is required to be vertical to the needle head, the needle head is connected with the threaded hole in the side wall of the handle. The oral cavity needle in this scheme passes through the handle and the syringe needle can dismantle the connection, has reduced the waste of handle, simultaneously through setting up two mutually perpendicular's screw hole, has realized being connected of syringe needle and the different angles of handle, has improved the range of application of oral cavity needle greatly, further reduces the use quantity of handle.

Further, the threaded hole at the end of the handle is coaxial with the handle. When the threaded hole is connected with the needle, the balance between the needle and the handle is kept, and the use is more convenient.

Furthermore, a placing cavity is arranged in the handle, a battery and a lamp control mechanism are arranged in the placing cavity, and the lamp control mechanism comprises a light emitting diode, a touch switch, a supporting plate, a spring, a sliding plate and a push rod fixedly connected to the sliding plate; the support plate is positioned between the touch switch and the sliding plate, one end of the spring is fixedly connected to the support plate, the other end of the spring abuts against the sliding plate, and the support plate is provided with a limiting hole for a push rod to pass through; one end of the push rod, which is far away from the sliding plate, is over against the touch switch; the light emitting diode is connected with the battery through the touch switch; the light emitting diode is positioned at the end part of the handle and is positioned at the same side of the threaded hole. Through the arrangement of a battery and a lamp control mechanism; after the screw hole that is located handle axis direction is connected to the syringe needle, continue to rotate the syringe needle, the tail end of syringe needle promotes the slide and removes to touch switch one side, after push rod contact touch switch, with emitting diode and battery intercommunication, and then for the syringe needle illumination to avoided the doctor to need the problem of exclusive use lighting device when carrying out oral disease treatment for the patient.

Furthermore, a groove is formed in the wall body of the handle, the extending direction of the groove is perpendicular to the axial direction of the handle, a lamp control mechanism is also arranged in the groove, and a sliding plate of the lamp control mechanism is over against a threaded hole in the side wall of the handle; the touch switch of the lamp control mechanism is positioned on one side of the groove far away from the threaded hole; and the light emitting diode of the light control mechanism is positioned on the side wall of the handle and is connected with the battery through the touch switch. Through setting up two accuse lamp mechanisms for no matter connect which screw hole can all realize rather than the LED circular telegram that corresponds, and then realize the illumination.

Furthermore, a transparent isolation plate is arranged on the periphery of the light emitting diode. The isolation board is arranged by enclosing, so that the direct contact between a human body and the light-emitting diode can be effectively avoided, and the use is safer.

Furthermore, the placing cavity and the groove penetrate through the handle, and a blocking block used for blocking the placing cavity and the groove is detachably connected to the handle. Through the setting of sprue, be favorable to guaranteeing the holistic seal of oral cavity needle, be favorable to the installation of handle inner part again simultaneously.
