Description

Replaceable Clinic Device for Dentist

The present invention relates to a replaceable dental clinical instrument, and more particularly, a clinical instrument for inhaling and discharging a substance in the oral cavity during a dental procedure, the elongated hollow cylinder for moving the substance sucked through the suction unit Structure, the front end of which is bent downward at a predetermined angle, a main body having a protruding fastening portion formed at an end of the front end, and a suction part which is mechanically coupled to the protruding fastening portion and sucks substances in the oral cavity It relates to a dental clinical instrument comprising an end tip formed, wherein the body and the end tip are made of a corrosion resistant metal.

In general, during a dental procedure, an inhalation device such as a suction tip is used to remove saliva, blood, and other foreign substances generated in the treatment area and the mouth of the patient.

The suction tip is a structure in which a wire is bonded to a plastic tube having a length of about 12 to 13 cm, and a single injection-molded plastic tip is uniformly used at the end of a freely bent or deformable body, or brass or Use a metal tip made of brass plating.

In the case of using a conventional metal suction tip during a dental procedure, since it contacts the patient's saliva and blood inside the oral cavity, pathogens such as viruses, bacteria, etc., which may exist in the patient, remain in the suction tip. In order to solve this problem, it is necessary to use a disposable plastic tip that uses a conventional metal suction tip and then cleans and sterilizes it, or uses and discards it only once.

However, the disposable plastic tip has a problem of increasing the dental treatment cost because the unit price is relatively high, and hygienic or safety problems occur when the disposable tip is disinfected and reused several times to reduce the cost. In addition, the suction tip of which the body is made of a plastic tube is easily deformed even with a small force, so it is inconvenient to pay close attention to positioning it in the desired suction area, and in the case of brass plated metal suction tips, autoclaving and In the same sterilization process, there is a problem that the brass plating is peeled off.

Therefore, there is a high need for a technology capable of solving the problems of conventional suction tips such as disposable suction tips or metal suction tips made of brass or brass plated by using a disposable synthetic resin material tip in a plastic tube.

The present invention aims to solve the problems of the prior art as described above and the technical problems that have been requested from the past.

That is, an object of the present invention, when using a clinical device such as suction to inhale and discharge the material in the oral cavity during the dental procedure, to suppress the rise of dental treatment costs by the use of disposable suction tips, and is convenient to use, manage and store To provide a dental clinical instrument consisting of a structure.

Dental clinical apparatus according to the present invention for achieving this object is a clinical apparatus for inhaling and discharging substances in the oral cavity during the dental procedure,

(A) is made of an elongated hollow cylindrical structure for moving the material sucked through the suction part, the front end portion thereof is bent downward at a predetermined angle, and the protruding fastening portion is formed at the end of the front end portion main body; And

(b) an end tip mechanically coupled to the protruding fastening portion and having an intake portion for sucking the substance in the oral cavity;

The body and the end tip are made of a corrosion resistant metal.

Therefore, the dental clinical apparatus according to the present invention is easily positioned at the suction site where the end tip is desired by using the front end of the body which is bent downward at a predetermined angle when the saliva and the blood are sucked in the oral cavity of the patient. It is easy to use because it can be used, and after use, the end tip, which is mechanically coupled to the clinical instrument body, can be removed and sterilized and reused, thus reducing the dental treatment cost compared to the high-cost disposable suction tip. It can solve the problem of pollution caused by the disposal of the disposable tip. In addition, since the body and the end tip is made of a corrosion-resistant metal, it can be easily managed because no deformation occurs during use or sterilization.

The end tip is not particularly limited so long as it is easily coupled with the protruding fastening portion of the main body, the dental clinical apparatus of the present invention can be used regardless of the type of dental treatment or the type of suction. It can be made of).

In particular, the structure of the clinical instrument is able to exchange end tips with diameters that are partially suitable for the purpose of the treatment while maintaining disinfection, and remarkably secure the field of vision of the operator by inhaling what is caused by bleeding during the procedure. Can be improved.

The structure for fastening the protruding fastening portion and the end tip of the main body is not particularly limited as long as it facilitates mechanical fastening with each other. For example, a thread is formed on the outer circumferential surface of the protruding fastening portion and an inner circumferential surface of the rear end of the end tip. It may be made of a structure.

When the clinical device is sterilized or disinfecting or replacing the end tip, since the frequency of separating or combining the main body and the end tip occurs frequently, it is easy to separate and combine with each other, and a fastening method that can maintain a stable coupling force during the coupling. It is preferable to apply. Therefore, by forming a thread corresponding to each other on the outer peripheral surface of the protruding fastening portion and the inner peripheral surface of the rear end of the end tip, it is possible to combine or detach the main body and the end tip in a simple and easy manner.

In addition, since the fastening structure can be replaced with various types of end tips, it can be used for various purposes as well as suction during dental treatment.

The suction portion of the end tip is preferably formed of a structure that easily inhales liquids such as saliva and blood in the oral cavity of the patient and does not adsorb with the tongue or other skin tissue of the oral cavity due to the suction force. Accordingly, the suction part may have a through hole formed at a central portion of the end tip, and two or more grooves may extend to the side of the end tip on the outer circumferential surface of the end tip with respect to the through hole. .

That is, when the through-hole is adsorbed to the tongue and other skin tissues in the patient's mouth in the process of inhaling the saliva and blood of the patient, the air is partially sucked into the grooves extending laterally from the outer peripheral surface of the end tip. As the pressure inside the through hole becomes similar to atmospheric pressure, the adsorption force of the through hole decreases, thereby preventing the tongue or oral skin tissue from sticking to the through hole.

Specifically, grooves formed in a radial structure around the through hole can easily absorb a liquid such as saliva and blood, and can suppress a phenomenon in which the through hole and skin tissue in the oral cavity are adsorbed.

In another preferred embodiment, the shear outer peripheral surface of the tip is formed in a downward taper structure toward the main body, the diameter of the end tip may have a size of 200 to 400% based on the diameter of the through hole.

That is, since the outer peripheral surface of the front end of the end tip has a tapered structure toward the main body, it is easy to perform suction by being located at a specific site where foreign substances, saliva, blood, etc. are concentrated in the oral cavity. Further, by forming the diameter of the end tip front end portion smaller than the diameter of the rear end portion, the end tip can be easily positioned in a desired specific area in the oral cavity.

In this structure, by forming the diameter of the through hole 200 to 400% smaller than the diameter of the end tip, the empty space inside the end tip has a lower air pressure than the through hole, and this pressure difference can improve the suction force in the through hole. .

On the other hand, the front end portion of the body which is bent downward at a predetermined angle is preferably made of an angle that can be most conveniently used when the user performs the suction by holding the body by hand, for example, the front end portion is horizontal It may be bent downward at an angle of 30 to 60 degrees with respect to the cross section.

As another example, the front end of the main body may be of a structure that is bent in a semi-circular shape. For example, the shear portion bent in the direction of the patient's treatment site has a semi-circular shape, and thus performs a ring role. When the bent portion is inserted into the oral cavity during the dental procedure, clinical instruments are naturally placed on the lips of the patient. Since it can be fixed, the operator can be treated alone without an assistant.

In addition, at least a part of the outer surface of the end tip is composed of a gentle tapered structure that is smaller in diameter in the direction of the end of the tip, so that the tip can be easily positioned at the treatment site.

Preferably, the through-hole of the end tip is formed in the central portion of the end tip, the inside of the end tip is composed of a multi-stage structure in which the diameter increases in the direction from the front end to the rear end, so that the suction force during suction is the front end of the end tip It can increase gradually from wealth to the rear end.

For example, in such a multi-stage structure, the tip type can be divided into small diameter, medium diameter, and large diameter according to the size of the front end diameter of the end tip, and is suitable for various applications as follows according to the size of the diameter. Can be used.

That is, the small diameter end tip is used to remove the small root remaining after extraction, the medium diameter end tip is used for suction after neurotherapy, and the large diameter end tip is used to remove a large amount of blood generated during surgery of the gum. It can be used to inhale.

In some cases, the rear end of the main body may be further equipped with a connecting member for connecting pipes of different diameters. For example, an adapter may be mounted as a connecting member for connecting the rear end of the main body and each end of the other pipe, and by using such an adapter, the adapter may be simply connected to each other while preventing leakage of the connection site. In particular, when connecting the pipe having a different diameter from the rear end of the main body it is possible to simply and stably combine them by using an adapter having a coupling portion corresponding to each diameter.

In addition, the connecting member may be particularly preferably used to join a small diameter clinical instrument body to a pipe that is continuous and relatively large in diameter, in order to increase suction power.

In this structure, the connecting member may be formed of a front hollow portion inserted into and coupled to the rear end of the main body and a rear hollow portion inserted into and coupled to the pipe. Specifically, one or more grooves may be formed on the outer surface of the rear hollow portion of the connecting member in the circumferential direction to increase the coupling force with the inner surface of the pipe. In addition, the inner surface of the front hollow portion of the connecting member is further formed with a fine jaw for setting the mounting position of the rear end of the main body, the rear end of the main body is caught by the fine jaw, it is possible to stably couple the main body rear end and the connecting member.

The corrosion resistant metal is not particularly limited as long as it has a proper strength as a suction tip and has no deformation of physical properties during sterilization and use, and for example, stainless steel that is durable and does not change material during autoclaving sterilization may be used. Can be.
