Abstract

The utility model relates to the technical field of medical instruments, belongs to a therapeutic tool in the department of stomatology, and provides a modified smooth broach. The modified smooth broach comprises a needle point, a needle body, a handle, a revolving ring, a hook, a chain ring and a finger ring, and is characterized in that the needle body bends to form an arc shape, the handle is provided with anti-skid screw threads, and the revolving ring is fixedly mounted at the tail end of the handle; the revolving ring is connected with a hook fixedly connected with the front end of the chain ring; and the tail end of the chain ring is fixedly connected with the finger ring. The utility model solves the problem that the angle of the smooth broach is required to be adjusted considerably during molar root canal therapy, reduces the probability of oral mucosal injury, improves the accuracy of the molar root canal therapy, effectively prevents the smooth broach from being swallowed into a digestive canal or directly dropping into a respiratory tract after slipping from hands, and has the advantages of simple operation, reasonable structure and convenient use.

Description

A kind of Improvement type smooth broach

Technical field

This utility model relates to technical field of medical instruments, belongs to department of stomatology therapeutic device, is a kind of Improvement type smooth broach.

Background technology

Pulpitis and apicitis are department of stomatology common diseases, are subjected to bacterial infection by the pulp tissue in the root pipe usually and cause degeneration necrosis to cause.Chang Yong Therapeutic Method is clinically: use dental therapeutic tool to open marrow, extract root pipe content and cleaning root pipe out, fill with root canal filling material then.Grind one's teeth in sleep position after dental arch leans on most, pulp chamber is bigger, has 3 root pipes at least, behind flushing cleaning root pipe, uses to be installed in the cotton that the aseptic absorbent cotton of employing on the smooth broach makes and to twist with the fingers, and blots in the root pipe moisture and envelope disinfecting drug temporarily.When normally used straight smooth broach dry root pipe and temporary envelope disinfecting drug, the angle that needs constantly to adjust smooth broach causes smooth broach to stab oral mucosa to comply with the direction of root pipe easily; Intraoral space is limited, and the angle of smooth broach is often adjusted not in place, influences the effect of molars root canals treatment; Because the smooth broach smooth surface, be infected with intraoral moisture of patient and saliva after, easily slippage is swallowed digestive tract by mistake or is directly fallen into respiratory tract when serious in the patient oral cavity, brings great misery to the patient.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of Improvement type smooth broach is provided.

The technical scheme that realizes this utility model purpose is such: a kind of Improvement type smooth broach, comprise needle point, needle body, handle, change, hook, chain link and Ring put around finger for massage of cavity of human body, it is characterized in that: needle body bending camber, handle have anti-skidding screw thread, and handle end is installed with change; The fixedly connected hook of change and the front end of chain link is connected the terminal fixedly connected Ring put around finger for massage of cavity of human body of chain link.

This utility model has avoided need adjusting significantly the angle of smooth broach in the molars root canals treatment, reduced probability to oral mucosa lesion, improved the degree of accuracy of molars root canals treatment, prevent effectively smooth broach from hands after the slippage mistake swallow digestive tract or directly fall into respiratory tract.Owing in this utility model change free to rotate is installed, can make chain link fast knot or button phenomenon occur during rotary manipulation; The chain link front end is installed with hook, and hook can make chain link be connected or break away from change easily, is convenient to change in root canal smooth broach.Has advantage simple to operate, rational in infrastructure, easy to use.

The specific embodiment

The technical scheme of embodiment of the present utility model is as follows: a kind of Improvement type smooth broach comprises needle point 1, needle body 2, handle 3, change 4, hook 5, chain link 6 and Ring put around finger for massage of cavity of human body 7.It is characterized in that: needle body 2 bends to arc, and handle 3 has anti-skidding screw thread, and handle 3 ends are installed with change 4; The fixedly connected hook 5 of change 4 and the front end of chain link 6 is connected the terminal fixedly connected Ring put around finger for massage of cavity of human body 7 of chain link 6.

During use, hook 5 is connected in change 4, and Ring put around finger for massage of cavity of human body 7 is placed in finger, and hand-held handle 3 allows needle body 2 be close to the pulp chamber sidewall of grinding one's teeth in sleep, and utilizes to be installed in cotton that the aseptic absorbent cotton of employing on the needle point 1 makes and to twist with the fingers the root pipe is carried out drying and seals disinfecting drug temporarily.When changing root canal, only need the slight handle 3 of adjusting to make needle point 1 comply with the root tube side to, complete operation smoothly.
