Description
SCALPEL FOR DENTAL SURGERY
TECHNICAL FIELD
The present invention relates to a scalpel for a dental surgery, and in
particular to a scalpel for a dental surgery which is capable of effectively pulling out
a tooth by cutting a certain portion in a gum along a circumference of a tooth when
performing a dental surgical operation in a dental surgery.
BACKGROUND ART
Generally, a scalpel for a dental surgery among various devices used for a
dental surgical operation is adapted to cut a certain tissue like a gum. As shown in
Figure 1 , a conventional scalpel for a dental surgery will be described.
The conventional scalpel for a dental surgery includes a holder B formed
of various kinds of blades A or in combination with the above blades A. An
assembling groove "a" is formed in each blade. A protrusion portion "b" is formed
in the holder B. When a certain blade is assembled to the holder B, the protrusion
portion "b" and the assembling groove "a" are integrally engaged each other.
In addition, in the above conventional scalpel for a dental surgery, the
shapes of the blades are different depending on the form of lateral face. Namely,
the blades are basically shaped in a straight line blade A1 , a hatched shape blade
A2, and a curve shape blade A3. The above various shapes of the blades are
selectively used based on whether the portions to be operated are externally
exposed to a line of teeth or the potions or internally exposed to a line of teeth and
based on the shapes of teeth to be operated.
In the above conventional blades, the blades A are different in the shapes
like a straight line blade A1 , a hatched shape blade A2, and a curve shape blade
A3 depending on the contour when laterally viewing the same. However, when
viewing the above blades on the plane, the blades are all straight line shapes.
Namely, in the conventional blades, the edges are fabricated in a flat
shape, and then the edges are further processed in a straight shape, hatched
shape and curve shape thereby forming a certain shaped blade. Namely, a blade
is formed in a straight line portion, hatched portion and curve portion.
In a conventional method for pulling out a tooth, after putting a patient
under anesthesia, a certain tooth is pulled out, since the portion from which the
tooth is pulled-out is large, it takes a long time for recovery of the above portion.
In addition, the tooth is generally formed in a column shape. In the case
that an operation is performed for cutting a gum along a circumference of a tooth,
when a conventional scalpel is used, as shown in Figure 2, the holder B held by a
hand becomes an operation point, and the tooth portion becomes a support point.
Therefore, an end portion of the blade A penetrating into a gum broadens the cut
portion, so that a cut portion is heavily formed in the gum.
DETAILED DESCRIPTION OF THE PRESENT INVENTION
Accordingly, it is an object of the present invention to provide a scalpel for
a dental surgery which overcomes the problems encountered in the conventional
art.
It is another object of the present invention to provide a scalpel for a dental
surgery which is capable of implementing a proper cutting operation by cutting a
gum along column shaped teeth by forming a blade in a concave shape in an end
portion of the same.
It is further another object of the present invention to provide pulling out a
tooth by simply cutting a gum using the above blade when pulling out a certain
tooth thereby minimizing the size of a cut portion.
In order to achieve the above objects, there is provided a scalpel for a
dental surgery in which a blade is formed in such a manner that a holder is
connected to a rear portion, and a front end and lower end are formed of an edge
of a blade, and in the blade 10, a holder assembly portion 12 is formed in a flat
shape, and an end portion 13 of the same is formed in a semicircular concave
shape in a longitudinal direction of the same, and an end portion of the
semicircular concave shaped portion is formed in an arc shape, and all
circumferences of the arc portion are formed of an edge of blade, so that it is
possible to easily cut a circumference portion of a certain tooth based on a
semicircular concave portion of the blade.

PREFERRED EMBODIMENTS OF THE PRESENT INVENTION
The preferred embodiments of the present invention will be described with
reference to the accompanying drawings.
Figure 3 is a perspective view illustrating a blade according to the present
invention, and figure 4 is a cross-sectional view of Figure 3.
As shown therein, in a blade 10 according to the present invention, the
construction that a holder B is connected to an end portion is same as the
conventional art. In the present invention, an edge is improved.
In the above blade 10, a holder assembling portion 12 is formed in a flat
shape in the same manner as the conventional art. The peripheral portions of the
edges of the end portion 13 are formed in a semicircular concave shape along a
longitudinal portion as shown in the front and plane views of Figure 4. An end
portion of the semicircular concave portion is formed in an arc shape for thereby
implementing an easier cutting operation in a circumference of a corresponding
tooth.
In addition, in another embodiment of the present invention, an end portion
of the blade may be formed in an arc shape, and then an arc shaped protrusion 11
may be further formed in the center portion of the same. Therefore, when cutting a
circumference of the tooth by processing the edges of the blade, the semicircular
protrusion portion 11 comes to a root portion of a tooth for thereby implementing
an effective operation.
In the above scalpel for a dental surgery according to the present
invention, when cutting a circumference of a tooth, as shown in Figure 6, it is
possible to perform a surgical operation without broadening the cut portions.
Namely, since the edge portions of the blade 10 are formed in a concave
cylindrical shape, when using the blade 10 in an upright shape, the concave
portion is closely contacted with a circumference of a column shaped tooth. In the
above state, a cutting operation is performed in the left and right directions, so that
it is possible to effectively perform a cutting operation in a state that the blade is
closely contacted with the tooth.
In the blade 10 according to the present invention, the operation direction
of the edges of the blade which is formed in a circular shape is defined in a
direction that the blade is closely contacted with a circumference of the tooth when
the cutting operation is performed in the left and right directions, so that the size of
the cut portion is minimized.
In addition, in the case that a semicircular shaped protrusion 11 is formed
in an end portion of the blade, when cutting a circumference of a certain tooth, the
semicircular protrusion 11 comes to a root portion of the tooth. Therefore, when
performing a cutting operation up to the root of the tooth, it is possible to
automatically pull out a certain tooth based on a simple cutting operation.
The scalpel for a dental surgery according to the present invention is not
limited to only a straight line shaped blade. The scalpel for a dental surgery
according to the present invention may be adapted to a hatched line shape blade
and a curve shaped blade.
As described above, in the blade according to the present invention, when
a cutting operation is performed along a circumference of a tooth, the cutting
operation is performed along a portion most near a corresponding tooth based on
a concave shaped end portion of the blade for thereby minimizing the size of a cut
portion. In addition, in the present invention, an end portion of the arc portion of
the blade is capable of cutting at a certain depth, and the cutting operation is
performed up to a circumference of a root of a tooth by a semicircular protrusion
portion. Therefore, it is possible to effectively perform a tooth pulling-out operation.
Therefore, the operator is capable of more easily performing a tooth
pulling-out operation. The patient has a smaller size of cut portion for thereby
decreasing the bleeding amount of blood. The pain is minimized, and the recovery
time is significantly decreased.
As the present invention may be embodied in several forms without
departing from the spirit or essential characteristics thereof, it should also be
understood that the above-described examples are not limited by any of the details
of the foregoing description, unless otherwise specified, but rather should be
construed broadly within its spirit and scope as defined in the appended claims,
and therefore all changes and modifications that fall within the meets and bounds
of the claims, or equivalences of such meets and bounds are therefore intended to
be embraced by the appended claims.
