Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to bushing type conveyor for root canal paste medicine.
Background
When child deciduous teeth have pulpitis or periapical periodontitis, the root canals cannot be filled with solid matters such as gutta-percha after removal of the dental pulp, root canal preparation and disinfection under local anesthesia, but are filled with absorbable iodoform paste and the like, because the permanent teeth of the child are continuously stimulated to absorb the root of the deciduous teeth when erupting, and if the permanent teeth of the child are filled with the solid matters such as gutta-percha, the normal replacement of the deciduous teeth can be influenced.
At present, when the deciduous tooth root canal filling operation is carried out in clinical medicine, a screw conveyer is usually adopted to convey paste medicines into the root canal, the working end of the screw conveyer is a long spiral steel wire which is easy to bend and break, and if the steel wire breaks in some tiny root canals, the steel wire is not easy to take out; especially for the children with low degree of matching, the risk of breaking the screw conveyor is greatly increased; the spiral conveyor is easy to generate bubbles in the root canal, so that the root is not dense; the use of a screw conveyor also leads to an overfilling phenomenon, increasing the pain sensation of the child patient.
In order to solve the technical problem, the utility model provides a bushing type conveyor for root canal paste medicine.
Disclosure of Invention
The utility model aims at overcoming prior art's is not enough, provides a bushing type conveyor for root canal paste medicine, can improve the security of clinical diagnosis, guarantees the root canal filling effect, reduces the influence to the oral cavity is healthy, and easy operation reduces the clinical operation degree of difficulty, shortens operating time, raises the efficiency, promotes the infant comfort level of seeing a doctor, alleviates the fear rejection psychology of infant.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a sleeve type conveying device for root canal paste medicines comprises a sleeve, a nickel-titanium needle, a handle part and a cover body, wherein one end of the sleeve is provided with a small opening, and the other end of the sleeve is in a pen point shape; one end of the nickel-titanium needle is provided with a positive thorn which is arranged in the sleeve, and the other end of the nickel-titanium needle passes through the small opening to be connected with the handle part; the cover body is connected with the other end of the sleeve.
Preferably, the inclination angle of the positive burrs ranges from 10 to 80 degrees.
Preferably, the positive stabs are arranged at least one turn, and each turn has at least 2 stabs.
Preferably, the cap is threadedly connected to the sleeve.
Preferably, the handle is provided with a model mark.
Preferably, the sleeve is made of PVC materials, so that the sleeve is good in adaptability and strong in flexibility.
Preferably, the positive puncture of the nickel titanium needle has a shape memory function and can keep a positive puncture shape.
When the device is used, the cover body is unscrewed to expose the pen-point-shaped end of the sleeve, then the pen-point-shaped end of the sleeve is aligned with the root tip of a target root canal, and the nickel-titanium needle is lifted and pulled for multiple times by holding the handle part, so that the paste medicine can be smoothly put into the root canal.
The utility model discloses beneficial effect lies in:
the utility model discloses a set up the nickel titanium needle that has just stinging in the sleeve pipe, the nickel titanium needle has the memory function, can keep just stinging the form, through carrying draw the nickel titanium needle alright in the root pipe is gone into to paste medicine in the sleeve pipe.
Adopt above-mentioned scheme, the utility model discloses can realize the packing of paste medicine through carrying and drawing the nickel titanium needle, can improve the security of clinical diagnosis, guarantee root canal filling effect, reduce the influence healthy to the oral cavity, easy operation reduces the clinical operation degree of difficulty, shortens operating time, raises the efficiency, promotes the infant comfort level of seeing a doctor, alleviates infant's fear and rejection psychology.
