Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a device for measuring gum thickness. Background Art

[0002] Gingival biotypes are generally divided into "thin" and "thick", and some people have proposed "medium", "extremely thin" and "extremely thick" classifications. They are key factors in evaluating the prognosis of crown lengthening, mucogingival surgery, guided tissue regeneration surgery and dental implant surgery. In the aesthetic area, the thickness of the gingiva plays a decisive role in the choice of treatment and the treatment results.

[0003] In the prior art, the gingival thickness can be measured by the Avanson measuring instrument, ultrasonic measurement, CBCT and CBCT combined with digital impression. The Avanson measuring instrument is used to clamp the gingival flap to be measured after the gingival flap is opened during surgery. The measurement value is relatively accurate, but the invasiveness of the gingival flap surgery affects the later recovery and aesthetics; the ultrasonic measurement method uses ultrasound to measure the gingival thickness, but the environment in the oral cavity is relatively complex and the measurement error is large; the CBCT method and the CBCT combined with digital impression method are too cumbersome to operate in the process of measuring gingival thickness. Utility Model Content

[0004] The main purpose of the utility model is to overcome the shortcomings of the prior art and provide a measuring device for measuring gum thickness by inserting a detection needle with an angle between the opening and closing part into the gums and measuring the gum thickness through an operating part and an opening ruler. The operation is simple and convenient and the measurement of gum thickness is accurate.

[0005] The utility model adopts the following technical solutions:

[0006] A device for measuring gum thickness comprises two detection needles, two operating handles and an opening scale, wherein the two operating handles are arranged crosswise so that there is a rotation fulcrum between the two operating handles, the two operating handles can rotate around the rotation fulcrum, the operating handles are divided into an opening and closing part and an operating part by the rotation fulcrum, the two detection needles are respectively arranged on the opening and closing parts of the two operating handles and an angle less than 180° is formed between the detection needles and the opening and closing parts, the opening scale is detachably arranged on the operating part of any one of the operating handles and the opening scale can move toward the other operating handle as the operating handles rotate, the opening scale is a fan-shaped structure and scale lines are arranged on the opening scale.

[0007] Furthermore, it also includes a rebound component, which includes a first spring sheet and a second spring sheet, the first spring sheet and the second spring sheet are respectively connected to the ends of the operating parts of the two operating handles, and the other ends of the first spring sheet and the second spring sheet are cross-connected. When the two operating handles are close to each other, the first spring sheet and the second spring sheet squeeze each other and apply a force to move the two operating handles away from each other.

[0008] Furthermore, an insertion hole is provided on the first spring sheet, and a limiting portion and an insertion head are formed on the second spring sheet, the limiting portion is arranged at an end of the second spring sheet away from the operating portion, and the insertion head is arranged on the limiting portion, and the width of the limiting portion is smaller than the insertion head and the second spring sheet, and the insertion head passes through the insertion hole so that the limiting portion is located in the insertion hole, so that the first spring sheet and the second spring sheet are detachably connected.

[0009] Furthermore, the operating handle includes a first operating handle and a second operating handle, the second operating handle is provided with an avoidance hole, one end of the opening scale is connected to the first operating handle, and the other end extends toward the second operating handle and passes through the avoidance hole, a reading rod is provided on the avoidance hole, and the reading rod is located on the side of the opening scale where the scale line is provided.

[0010] Furthermore, the upper and lower surfaces of the aperture ruler are provided with scale lines, the avoidance hole is provided with two reading rods, and the two reading rods are arranged in parallel and spaced apart to form a space between the two reading rods for the aperture ruler to move.

[0011] Furthermore, a mounting plate is formed at one end of the aperture gauge connected to the first operating handle, a through hole is formed on the mounting plate, a mounting groove is formed on the first operating handle, a screw hole corresponding to the through hole is formed in the mounting groove, a bolt is arranged in the through hole, the mounting plate is embedded in the mounting groove so that the through hole faces the screw hole, the bolt passes through the through hole and is threadedly connected to the screw hole, thereby connecting the aperture gauge to the first operating handle.

[0012] Furthermore, it also includes a limiting component, which includes a limiting bolt and a locking nut. A limiting screw hole is opened on the operating part of any of the operating handles. The limiting bolt is arranged in the limiting screw hole through a threaded connection and the threaded end of the limiting bolt at least partially protrudes from the limiting screw hole. The locking nut is arranged on the limiting bolt, and the locking nut is located between the limiting bolt and the operating part.

[0014] Furthermore, anti-slip patterns are formed on the operating portion.

[0015] Furthermore, the length of the opening and closing portion is shorter than the length of the operating portion.

[0016] From the above description of the utility model, it can be seen that compared with the prior art, the beneficial effects of the utility model are:

[0017] First, by using the detection needle that forms an angle with the opening and closing part, when measuring the gum thickness, there is no need to open the gum flap, and the needle can be directly inserted into the gum. The opening of the opening and closing part can be controlled by the operating part, and the detection can be performed by the opening ruler on the operating part. The operation is simple and convenient, and the measurement accuracy is high. At the same time, because an angle is formed between the detection needle and the opening and closing part, when measuring the gums deep in the oral cavity such as the posterior molars, the detection needle can be directly inserted into the gums to be measured after the opening and closing part is inserted deep into the oral cavity. There is no need to rotate the direction of the detection needle, which is convenient for detecting the gum thickness on the posterior molars.

[0018] Second, by setting up a rebound component, during the detection process, when the opening degree of the opening and closing part is controlled by the operating part, the rebound component can provide a certain resistance to prevent the medical staff from applying excessive force and causing discomfort to the patient, and after the detection is completed, the rebound component can reset the opening and closing part through elastic force.

[0019] Third, the insertion hole and the insertion head facilitate the disassembly and assembly of the rebound assembly, and the limiting portion ensures that the first spring sheet and the second spring sheet can squeeze each other to generate elastic force, so that the rebound assembly can be detachably arranged while ensuring the normal function of the rebound assembly.

[0020] Fourth, through the avoidance hole and the reading rod set on the avoidance hole, the opening ruler can pass through the avoidance hole and move at the avoidance hole. The reading rod on the avoidance hole can read the scale on the opening ruler to obtain the gingival thickness value. The setting of the double reading rod makes it possible to accurately read the reading on the opening ruler in either direction, thereby improving the measurement accuracy.

[0021] Fifth, the maximum swing amplitude of the operating part is limited by the limit component, thereby limiting the minimum spacing between the detection needles on the opening and closing part, to prevent the detection needles from squeezing the gums and causing discomfort to the person being tested due to excessive operation.

[0022] Sixth, the indented lines on the detection needle can be used to measure the gum thickness and the gum length at the same time. The spacing between the indented lines is equal, and the gum length can be converted by the number of inserted indented lines. The operating part is provided with anti-slip grooves to prevent the operating handle from rebounding due to hand slipping during operation, which affects the measurement process.
