(57) [Summary] [PROBLEMS] To provide a portable portable dental instrument that takes care of safety measures and prevents hospital-acquired infection caused by a tip blade contaminated with pathogenic bacteria. A female screw (2) is engraved on the inner periphery of one end, and a chip holder (4) with a slit for covering a holder cap (3) is protruded from the other end. The screw stopper 8 of the chip holder with slit 7 to be inserted with the non-rotating grip 51 and held by the holder cap 6 is screwed, and a plurality of spare blade tips 5 are stored in the hollow space of the storage holder body 1. In this way, the present invention is characterized in that the portable protection cap 9 is covered with the blade tip 5 held bare by the tip holder 7.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an instrument with a medical cap that protects the human body from injuries caused by the cutting edge, and safely protects and holds the cutting edge to make it portable.

[0002]

[Problems to be solved by the invention]

 In recent years, nosocomial infections such as hepatitis B, AIDS, and tuberculosis have become a problem in medical practice, but this was caused by stab accidents caused by scalpels or needles contaminated with blood containing pathogenic bacteria. It has been raised as one of the causes. In dental care, infections caused by the above-mentioned accidental stings are inevitable. Therefore, in dental technicians, disinfection of impressions, sterilization of plaster models, wearing of masks, gloves and goggles during work Although they are obliged and enforced to prevent infection, they are not always perfect.

[0003] That is, in the case of dental technicians, various types of chisel instruments have sharp cutting edges, but in general, they are used side by side with the sheathless cutting edges exposed. Therefore, doctors and dental technicians often injure their fingers, etc., especially when moving, they may be injured because they are carried with the blade edge up in the chest pocket or side pocket. In many cases, it cannot be denied that safety precautionary measures against the danger of biological factors (biohazard) have been overlooked.

[0004] The present invention provides a portable instrument which is convenient to carry with sufficient consideration of safety measures.

[0005]

[Means for Solving the Problems]

 According to the present invention, a female screw 2 is engraved on the inner circumference at one end, and a chip holder 4 with a slit for covering the holder cap 3 is protruded at the other end. A screw stopper 8 of a chip holder 7 with a slit to be inserted with a non-rotating grip 51 and held by a holder cap 6 is screwed in, and a plurality of spare blade tips 5 are stored in the hollow of the storage holder body 1. In this way, the present invention is characterized in that the portable protection cap 9 is covered with the blade tip 5 held bare by the chip holder 7.

[0006]

[Embodiment of the invention]

 In general, craftsmen who produce things use various tools in various ways, and there are many types of tools, but even dental technicians who make technical products have devised usability. I use tools. And the starting point of manufacturing is to start with the tools that make them, but it is the most important requirement that the tools first have safe specifications.

[0007] A chisel instrument, which is a representative tool used in various operations of a dental technician, is one of the most basic blades, and is used for adjusting a fine part of a plaster model and for various kinds of wax. It is an indispensable tool for the production of restorations that require precise fitting in the order of microns by performing delicate engraving work, but the cutting edge of the chisel is sharp or obtuse. It has a wide variety of shapes, such as those without a sheath, and in general, many of them have an exposed blade edge.When carrying several pieces together, for sharp objects, Great care must be taken for injuries such as fingers and arms. In fact, safety precautionary measures against the dangers of biological factors (biohazard) have been overlooked.

The present invention proposes an instrument of a chip storage type which is convenient to carry in consideration of this safety measure. When the instrument and the holder main body are made detachable, a spare tip is used. It is stored in the storage holder body, and the sharp edge tip is covered with a portable protective cap so that it can be carried safely.

That is, FIG. 1 shows a side cross section of the storage holder main body. A detent grip 51 of a blade tip 5 to be used is held by a holder cap 6 which is fitted into the tip holder 7 and screwed thereto. In this case, several types of cutting tips are stored in the storage holder body 1 as spares, and are screwed and stored with the screw plugs 8 of the tip holder 7. By changing the tip 5 to the tip holders 4 and 7 as needed, it is possible to immediately start various and complicated work anytime and anywhere. That is, the blade tip 5 can be efficiently held by being held on both sides of the storage holder main body 1 by type. When moving with carrying this, one of the blade tips 5 is turned over, housed in the chip holder 4, held by the holder cap 3, and the other is held bare. If the mobile phone protective cap 9 is fitted, the blade tip 5 of the tip holder 6 is covered, and it is attached to the breast pocket with a nail, the blade tip 5 is protected. Work can be handled efficiently, and it can be carried safely without injury and without damaging the tip. Therefore, it is possible to prevent injuries to the practitioner as well as to prevent the infection of bacteria-infected chips, especially to prevent accidents by medical students and inexperienced apprentices. It is also possible to strongly recognize where responsibility is attributed to the individual. The detent grip 51 of the blade tip 5 is fixed without turning when it is fitted into the tip holder 6 as a polygonal column.

[Effect of the invention]

 According to the present invention, it is possible to prevent a stabbing accident caused by the blade tip of the instrument tip, which has been a problem in the past, and to prevent hospital-acquired infection at a medical site due to pathogenic bacteria on the blade tip when contaminated, This has the effect of improving the working efficiency by easily carrying several types of spare chips while carrying them safely and conveniently.
