Multifunctional telescopic root canal measuring instrument

Abstract

The invention discloses a multifunctional telescopic root canal measuring instrument, and belongs to the technical field of medical instruments. One end of a measuring instrument body is fixedly connected with radially symmetrical fixing plates, the side faces of the fixing plates are sleeved with short rods, the surface of one end of each short rod is in threaded connection with a threaded sleeve, the surface of each short rod is sleeved with a fixing gear, the surface of the fixed gear is fixedly connected with a connecting pipe, one end of the connecting pipe is provided with a storage hole, and the inner wall of the storage hole is connected with a threaded block through threads. According to the multifunctional telescopic root canal measuring instrument, through arrangement of the clamping block and the fixing gear, the root canal expanding needle has the function of adjusting the inclination angle, and the root canal expanding needle has the telescopic function, so great use convenience and comfort are brought to a user; the use safety is improved through the arranged oral cavity hanging piece; and the electrical conductivity is ensured through the arranged conductive strip, meanwhile, the detachable and combined functions are achieved, and assembly and later independent replacement are facilitated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multifunctional telescopic root canal measuring instrument. Background technique [0002] Root canal length is a parameter often measured by dentists. In the modern medical industry, especially in the field of stomatology, high requirements are placed on the performance and size of auxiliary tools. [0003] But most of the root canal expansion needles of the existing multifunctional root canal measuring instruments are fixedly connected with the measuring instrument. During use, the user's hand needs to be bent to facilitate its use, but the hand remains bent for a long time, not only It is laborious, and it is not convenient to operate the root canal expansion needle, which brings great discomfort to the user, and the length of the existing root canal expansion needle is mostly fixed, without the function of adjusting its telescopic length. It brings some inconven...

Problems solved by technology

[0003] But most of the root canal expansion needles of the existing multifunctional root canal measuring instruments are fixedly connected with the measuring instrument. During use, the user's hand needs to be bent to facilitate its use, but the hand remains bent for a long time, not only It is laborious, and it is not convenient to operate the root canal expansion needle, which brings great discomfort to the user, and the length of the existing root canal expansion needle is mostly fixed, without the function of adjusting its telescopic length. It brings some inconvenience to the user during actual use. At the same time, the wires of the existing multifunctional root canal measuring instruments are mostly fixed to the patient's lip by stainless steel hooks. The stainless steel hooks not only have poor electrical conductivity, but also easily scratch the patient's mouth. For this reason, we have designed a multifunctional telescopic root canal measuring instrument to solve the above problems
