The present invention relates to a medical forceps and a method of manufacturing the same, and more particularly, having a locking member and a guide member is convenient to use, and medical forceps that can be prevented from environmental pollution because it is easy to decompose by producing a biodegradable material and It relates to a manufacturing method.

In general, forceps (FORCEPS) is a device that is used to fix the tissue when closing the wound, or to build a blood vessel when bleeding small blood vessels.

Such forceps typically have a shape similar to a forceps, ie two arms joined together in a hingeable structure.

Therefore, when a doctor or a nurse performs a procedure using such a medical forceps in a hospital or the like, the arm is picked up with two arms by an external force and the wound is picked up or a cotton ball for disinfection is performed.

In addition, such medical forceps are generally manufactured by a forging method. In other words, the forging method is to grind the pin after the die forging, to adjust the dimensions through machining and grinding work, heat treatment, finishing with buffing, electropolishing and polishing.

However, the medical forceps having the structure as described above may affect the procedure because the user accumulates fatigue on the back of the hand because the user performs the procedure while holding the forceps by applying external force for a long time. There is a problem that can be.

In addition, since the medical forceps are made of iron, stainless steel, or synthetic resin, it is difficult to decompose during disposal, which may cause environmental pollution.

Accordingly, the present invention has been proposed to solve the above problems, and an object of the present invention is to provide a medical forceps that can prevent the accumulation of fatigue in the hand even when used for a long time.

Another object of the present invention is to provide a medical forceps that can be prevented from environmental pollution by being easily decomposed at the time of disposal by producing a biodegradable material.

In order to achieve the above object, the medical forceps according to the present invention are formed to branch and face each other with respect to one point and have elasticity; A pair of locking members provided inside the first and second arms and coupled to each other to integrally fix the first and second arms, wherein the first and second arms and the pair of locking members are biodegradable. 10 to 60% by weight of the active material and a binder in a ratio of 40 to 90% by weight, the inner side of the first and second arms are provided at a position away from the pair of locking members a predetermined distance from the first and second 2 When the arm is pressed inward further comprises a guide for guiding to be pressed into position.

Hereinafter, a medical forceps and a manufacturing method according to a preferred embodiment of the present invention with reference to the accompanying drawings will be described in detail.

1 to 3, the medical forceps proposed by the present invention includes first and second arms 1 and 3 arranged to be hingedly connected to each other with respect to one point.

In addition, the concave and convex portions 9 are formed at the end portions 5 and 7 of the first and second arms 1 and 3 so that they can be easily picked up by a constant frictional force when picking up wounds or cotton wool.

Thus, when the user grabs the two arms 1, 3 and exerts an external force, the two arms 1, 3 can be retracted inward or unfolded outwards to pick up the wound.

In addition, a pair of locking members 15 are provided inside the first and second arms 1 and 3, and the locking member 15 integrates the first and second arms 1 and 3. Function to fix it.

That is, as shown in FIG. 4, the pair of locking members 15 protrude inwardly from the first engaging bar 11 protruding inwardly from the first arm 1 and the second arm 3. It is formed of a first locking bar 11 and the second locking bar 13 is caught by each other by a screw thread.

In addition, threads 30 and 31 having a predetermined pitch are formed on the bottom surface of the first locking bar 11 and the top surface of the second locking bar 13.

In this case, the first and second engaging bars 11 and 13 are formed of a material having a predetermined elasticity. Accordingly, when the first and second arms 1 and 3 are pressed inward by applying an external force, the thread 30 of the first catching bar 11 meshes with the thread 31 of the second catching bar 13. As a result, the first and second arms 1, 3 can be fixed integrally.

In addition, the first and second guide parts 17 and 23 protrude from the pair of locking members 15 at a predetermined distance.

Therefore, when the first and second arms 1, 3 are pressed inwards, the locking members 15 are held in place without the two arms being displaced by the first and second guide parts 17 and 23. To be fixed to each other.

This first guide portion 17 is composed of a first protruding bar 19 protruding from the inner side of the first arm 1 and a second protruding bar 21 protruding from the inner side of the second arm 3.

An inclined surface 25 in an upper direction is formed at the tip of the first protrusion bar 19, and an inclined surface 27 in a lower direction is formed at the tip of the second protrusion bar 21.

Accordingly, when the first and second arms 1, 3 are pressed inward, the first protrusion bar 19 approaches the second protrusion bar 21, and the inclined surfaces 25, 27 are in contact with each other. The first and second arms 1, 3 are guided to each other in a fixed position.

Since the second guide part 23 has the same structure as the first guide part 17, a detailed description thereof will be omitted below.

In the above description, the guide part proposed by the present invention is not limited thereto. Only one guide part may be formed, or three or more guide parts may be formed.

On the other hand, Figure 5 shows a medical forceps having the shape bent its end as another preferred embodiment of the present invention. As shown, the two arms 41 and 43 are arranged to face each other about one point, and each end 45 and 47 is upwardly bent at a predetermined angle θ with respect to the horizontal plane. .

Therefore, the user can perform a medical procedure using the medical forceps of the above-described shape.

On the other hand, medical forceps having such a structure may be manufactured by biodegradable plastics. That is, the manufacturing material of the medical forceps proposed by the present invention consists of a biodegradable material and a binder mixed with the biodegradable material.

The biodegradable material is typically used for several months (1 to 2 years; in the case of general plastics) by simply landfilling the plastic used as a molded article, packaging agent, hygiene product, agricultural product, etc. It is a plastic that is completely decomposed into water, carbon dioxide, and methane gas within a few years.

The biodegradable resins currently developed are starch-based biodegradable plastics prepared by mixing nontoxic natural starch with general purpose plastics or developed biodegradable plastics, and ring opening reactions for chemical catalytic enzymes from lactic acid or lactide. It is divided into polylactide, epsilon-caprolactone, and other aliphatic polyester-based biodegradable plastics synthesized through. These biodegradable substances are classified as follows.

division Starch (starch) Aliphatic Polyester Biodegradable, photodegradable series Manufacturing method Add additives to corn and potatoes and process them with an extruder Chemical or microbial fermentation Additive Extraction from Soybeans-Extraction or Aerospace Processing characteristic Excellent tensile strength, moisture resistance and workability Low price, 100% biodegradation, tensile strength, excellent workability

In addition, the biodegradable material and the binder are mixed at a predetermined ratio, preferably 10 to 60% by weight of the biodegradable material and 40 to 90% by weight of the binder are mixed with each other.

In addition, if necessary, the biodegradable material and the binder may be mixed with each other, and then a preservative or bleach may be mixed.

In addition, the process of manufacturing a medical forceps using the biodegradable material comprises the steps of mixing the raw materials with each other, and injecting the mixed material into a mold having a shape of the medical forceps to compression molding.

In the step of mixing the raw materials, the biodegradable material and the binder and the like as described above are mixed with each other in a predetermined ratio. At this time, the mixing ratio may be appropriately changed.

In the compression molding step, the mixed biodegradable material is collected in a mold having a predetermined shape. The mold is preferably manufactured to have the same shape as the medical forceps.

Then, the biodegradable material is injected into such a mold and pressurized to a predetermined pressure or heated with heat.

Through this process, medical forceps of biodegradable materials can be prepared.

Hereinafter, a case of working using a medical forceps having the structure as described above is as follows.

When a user such as a doctor or a nurse wants to perform a medical procedure using a medical forceps, first, the first and second arms 1 and 3 are grasped and an external force is applied inwardly.

The first and second arms 1, 3 retract inward by an external force, and the first and second guide parts 17, 23 approach each other.

As the first and second guide parts 17 and 23 approach each other, the inclined surfaces 25 and 27 of the first and second protruding bars 19 and 21 come into contact with each other, thereby allowing the first and second arms 1, 3) is guided to the correct position without shifting each other.

When the first and second guide portions 17 and 23 come into contact with each other, the first and second locking bars 11 and 13 may then approach each other, and the threads 30 and 31 of each other may be caught.

Accordingly, the first and second arms 1 and 3 may be fixed while being engaged with each other, and the user may hold the forceps in the fixed state and perform a medical procedure without applying an external force.

On the contrary, when it is desired to release the fixed state of the medical forceps, the first and second arms 1 and 3 which are in engagement with each other are slightly pressed inward.

At this time, the screwing state of the first locking bar 11 and the second locking bar 13 is released by pressing the first and second arms 1 and 3 in the displaced directions.

Therefore, when the first and second engaging bars 11 and 13 are released, the first and second arms 1 and 3 are returned to their original positions in the open state by their elasticity.

As described above, the medical forceps according to the preferred embodiment of the present invention has an advantage of being able to perform the procedure for a long time without applying any external force during the medical procedure by applying the locking member.

In addition, there is an advantage that the arm can be pressed to the right position without deviating from each other when applying the guide portion to the arm of the medical forceps.

In addition, the biodegradable material is easily decomposed at the time of disposal, thereby preventing the occurrence of environmental pollution.
