Description

scalpel blade remover {BLADE REMOVER FOR MES}

The present invention relates to a scalpel blade remover, and more particularly, to a scalpel blade remover capable of safely and conveniently removing a blade of a scalpel used for medical purposes.

The scalpel is used in a variety of ways, such as in medical institutions and research institutions. It is difficult to use the scalpel for incision of other biological tissues because the biological tissue is attached to the surface during the incision process of biological tissue, and it is used by replacing with a new blade every time due to contamination concerns.

1 (a) and (b) are diagrams showing the configuration of a general scalpel 10. As shown, the scalpel 10 connects a handle 11 held by the operator by hand, a blade coupling block 13 coupled to the front end of the handle 11, and the blade coupling block 13 and the handle 11. It includes a neck 15 and a blade 17 detachably coupled to the blade coupling block 13.

A guide groove 13a into which the blade 17 is inserted is formed in the blade coupling block 13, and a coupling hole 17a fitted into the guide groove 13a is formed inside the blade 17.

The operator inserts the blade coupling block 13 into the coupling hole 17a in an inclined direction and then pushes it in a horizontal direction so that the guide groove 13a fits into the coupling hole 17a as shown in (b) of FIG. and the blade 17 and the blade coupling block 13 are coupled.

However, a safety accident may occur when an operator presses the blade 17 with his or her hand to exchange the scalpel 10 to which the blade 17 is coupled. Accordingly, the blade 17 was separated using a tool such as tongs or pliers.

Accordingly, the blades were separated using a blade removal device such as “medical scalpel blade remover” registered in Patent No. 10-2190219.

In the disclosed conventional medical scalpel blade remover, when a blade is inserted horizontally into the inlet and then the scalpel is pressed against the handle support, the blade is lifted and hung by the principle of a lever, and the blade is separated from the blade coupling block.

When the blade coupling block 13 is inserted into the block insertion groove 132, the scalpel 10 is guided straight toward the center along the gradually narrowing path of the block insertion groove 132.

A blade insertion guide projection 133a forming a blade insertion groove 133 is provided above the lower inclined guide projection 132a. As shown in (b) of FIG. 4, the blade insertion guide jaw 133a is formed as an inclined cover surface that gradually increases from the front to the rear. Accordingly, when the operator inserts the scalpel 10, the blade 17 can be inclinedly inserted along the inclined cover surface of the blade insertion guide jaw 133a.

At the rear of the lower inclined guide jaw 132a, a rear horizontal support surface 133b is formed horizontally with a predetermined area. The rear horizontal support surface 133b supports the blade 17 so that the tip of the inclinedly inserted blade 17 does not droop downward so that the blade 17 can come into contact with the separation eaves 135 and be separated.

That is, as shown in (a) of FIG. 5, when the blade coupling block 13 and the blade 17 are inserted into the collection box 110, the lower inclined guide jaw 132a supports them so that they can be inserted obliquely. , When the handle 11 is lifted upward as shown in FIG. 5 (b) to separate the blade coupling block 13 and the blade 17 inserted into the interior, the rear horizontal support surface 133b is It contacts with (17) and holds the position of the blade.

As shown in FIG. 3, the separation eaves 135 protrude outwardly from the lower end of the cover 120 to cover the scalpel insertion port 131, and the blade 17 cannot be discharged to the outside of the scalpel insertion port 131 and is combined with the blade. The blade 17 is contacted and supported to be separated from the block 13.

As shown in FIG. It includes a vertical support jaw (135b) formed extending to.

The inclined cover surface 135a is provided to protrude outward by a predetermined length more than the protruding length of the scalpel insertion port 131. And, the vertical support jaw (135b) is positioned lower than the rear horizontal support surface (133b) a certain height (h).

Accordingly, when the scalpel blade remover 100 is viewed from the front from the outside, the blade insertion groove 133 is not completely exposed to the outside because it is covered by the vertical support jaw 135b. In addition, as shown in FIG. 5 (b) and FIG. 6 (b), the position of the blade coupling block 13 inserted into the collection box 110 and the blade 17 when the blade 17 is lifted The lower end of the vertical support jaw (135b) is located lower than.

As shown in (a) of FIG. 7, when the operator pulls the handle 11 backward, the rear 17-1 of the blade 17 comes into contact with the inner wall surface of the lower end of the vertical support jaw 135b, and the blade 17 prevent external discharge of

In this state, when the operator slightly lowers the handle 11 and pulls it outward as shown in (b) of FIG. 7, the blade 17 is caught on the vertical support jaw 135b. As a result, the blade coupling block 13 is separated from the coupling hole 17a of the blade 17.

Then, the handle 11 is discharged out of the scalpel insertion hole 131, and the waste blade 17' separated from the blade coupling block 13 is received at the bottom of the collection box 110.

The operating process of the scalpel blade remover 100 of the present invention having such a configuration will be described with reference to FIGS. 2 to 7.

When the operator desires to remove or replace the blade 17 of the used scalpel 10, as shown in FIG. 2, the operator holds the collection box 110 with one hand and the handle 11 with the other hand.

Then, the blade 17 is inclined downward at a predetermined angle θ1 toward the scalpel insertion hole 131, and the handle 11 is pushed so that the blade 17 is directed toward the blade insertion groove 133.

5(a) and 6(a), when the handle 11 is pushed in, both the blade 17 and the blade coupling block 13 are inserted into the collection box 110, and the neck ( 15) is mounted on the lower inclined guide jaw 132a.

In this state, the operator lifts the handle 11 upward as shown in FIG. 6(b). The blade 17 is moved along the inclined surface of the blade insertion guide jaw 133a and then positioned horizontally or inclined on the rear horizontal support surface 133b.

When the blade 17 touches the rear horizontal support surface 133b, the operator pulls the handle 11 outward from the collection box 110 as shown in FIG. 7(a). At this time, since the vertical supporting jaw (135b) extends below the rear horizontal supporting surface (133b), the rear (17-1) of the blade 17 collides with the vertical supporting jaw (135b) and the movement is prevented.

When the handle 11 is slightly rotated downward and pulled outward while the rear 17-1 of the blade 17 is in contact with the vertical support jaw 135b, the blade 17 is in a fixed state, so the blade 17 The blade coupling block 13 comes out of the coupling hole 17a and is separated.

The separated waste blades 17' fall on the bottom of the collection box 110 and are accommodated, and the scalpel 10 is discharged to the outside of the collection box 110.

As described above, the scalpel blade remover of the present invention has a simple structure of a collection box and a cover in which the blade removal unit is integrally formed, so that the operator inserts the scalpel obliquely into the scalpel insertion hole, lifts it upwards, and removes the blade with a simple operation of pulling it outward. can

Since the operator's hand or a separate tool is not required, safety accidents can be prevented, and the waste blade can be safely collected.

In addition, the scalpel insertion hole and the separation eaves are formed to protrude outside the collection box, so that when the user inserts the blade at an angle, the insertion angle can be increased, thereby reducing the probability of failure when separating the blade.

In addition, the blade removal operation can be performed regardless of the number of waste blades accommodated therein.

On the other hand, the scalpel blade remover of the preferred embodiment of the present invention described above can freely move the collection box. Accordingly, the user separates the blade by inserting it into the collection box while holding the collection box with one hand and holding the scalpel with the other hand.
