Description

Needle-pricker with replaceable handle for thread burial

Technical Field

The present invention relates to a needle-punching device for thread burial, and more particularly, to a needle-punching device for thread burial having a replaceable handle, which is used by replacing a plurality of thread burial needles with one handle.

Background

Generally, a medical thread is embedded in a human body by embedding a biological thread soaked with a liquid medicine or a suture thread which can be dissolved and disappear after a certain period of time in the human body into a part to be operated in the subcutaneous part of the human body by using an injection needle, and during the period when the thread is dissolved and disappeared, the reaction of human body physiological tissues induces the smoothness and tissue generation of the embedded part of the medical thread, thereby promoting blood circulation and strengthening muscles.

In the thread embedding operation, a part of a medical thread is generally introduced into a needle by using an injection needle, and after the part embedded into a human body is exposed, the medical thread is parallelly penetrated into the hypodermis of the human body and then pulled out, the medical thread is left at the position of the needle, and the medical thread is embedded into the human body.

Therefore, the medical wire inserted into the human body can play a role in healing the human body.

However, when a thread is buried in a human body, a needle needs to be inserted into the human body, and pain is likely to occur due to the characteristics of the operation.

The above-described catgut embedding operation is generally performed in many cases, several tens or even several hundreds of catgut embedding operations, and the operation is directly grasped by the operator with the hand only by the needle, so that the hand is extremely fatigued, and it is difficult to perform a large number of catgut embedding operations for a long time. When the suture is buried in the human body, the operation angle and the skin layer are almost horizontal, but when the needle is grasped by a hand to perform the operation, the operation angle is increased according to the position of the hand, and therefore, the operation angle is difficult to be close to the horizontal.

The needle causes pain after penetrating a blood vessel or a muscle layer, and when a large amount of medical wires are embedded in a human body, the accuracy of embedding tends to decrease.

In order to solve the above problems, Korean laid-open patent No. 10-2003-0094665 (title of the invention: a thread inserter for muscle reinforcement, patent document 1) discloses a technique which has a handle and can grasp the handle to embed a thread into a human body.

However, in patent document 1, the thread burial needle body and the handle are integrated, and when the needle is discarded, the entire thread burial needle needs to be discarded due to a hygienic problem after one use, which causes some cost loss.

The handle of patent document 1 has a flat plate shape, and is poor in stability when held by a hand of a surgeon. Moreover, as described above, even several hundred lines need to be embedded during the operation, which tends to increase the fatigue feeling of the user.

Detailed Description

An embodiment of the present invention of a needle-pricker with a replaceable handle for catgut implantation will be described in detail below with reference to the accompanying drawings.

Fig. 1a is a perspective view showing a combined shape of a needle punch for thread burial according to an embodiment of the present invention, and fig. 1b is a perspective view showing an exploded shape of the needle punch for thread burial according to an embodiment of the present invention.

Referring to fig. 1a and 1b, in the case of performing an operation for embedding a medical thread into a human body, a thread burial needle body for embedding the thread into the human body can be detached from a handle, and the thread burial needle body can be used by merely replacing the thread burial needle body.

To this end, the thread burial needle punch with a replaceable handle according to an embodiment of the present invention is substantially composed of aneedle 10, a threadburial needle body 20, and ahandle 30.

Theneedle 10 is formed with athread fixing hole 11 penetrating theneedle 10 in the longitudinal direction.

Thethread fixing hole 11 fixes thethread 40 from being separated from theneedle 10 when a part of thethread 40 embedded in the human body is inserted into the inside and thethread 40 is inserted into the inside of the human body.

Thethread fixing hole 11 may also serve as a passage for injecting the medicine when the medicine is additionally injected on thethread 40 as needed.

Therefore, when the thread embedding operation is performed, thethread 40 can be accurately embedded in the position to be embedded, and the drug can be additionally injected as needed.

One end of theneedle 10 is sharp, and a cutting slope is formed along the longitudinal direction of theneedle 10, and the other end is integrally coupled to the threadburial needle body 20.

The cutting inclined surface 22 is formed in a direction opposite to a direction in which agrip wing 32 of ahandle 30 is extended when the buried needlemain body 20 integrated with theneedle 10 and thehandle 30 described later are combined.

Theinclined cutting surface 12 is formed to be sharp at the skin-piercing end portion and inclined downward in the longitudinal direction in order to reduce the resistance of the skin when theneedle 10 pierces the skin.

When the skin penetrates into the dermis layer through the epidermis layer, the skin is gently passed over the uneven surface of the fat layer and the muscle layer at the lower part of the dermis layer by cutting theinclined surface 12 without being caught by the uneven surface.

Therefore, when the catgut embedding needle is inserted, the muscle layer inducing pain is not stimulated, and the pain feeling during operation can be reduced.

The threadburial needle body 20 is integrally coupled to theneedle 10 for burying themedical thread 40 in the human body at a front end portion thereof, and agrip groove 21 for detachably coupling the threadburial needle body 20 to thehandle 30 is formed at a rear end portion thereof.

Theclip groove 21 is formed by recessing the rear end portion of the buried needlemain body 20 toward the inside of the buried needlemain body 20, and is clipped at theclip portion 31 of thehandle 30.

Handle 30 and thebody 20 of the burial needle may then be replaced as desired.

The space inside theneedle body 20 is empty, and a medical solution is supplied from asyringe 50 described later.

Thehandle 30 is composed of agrip portion 31, agrip wing 32, and ahandle operation portion 33.

Theclip 31 is provided on the front surface of thehandle 30, is formed to correspond to theclip groove 21 of theneedle burial body 20, and is configured to clip or separate theneedle burial body 20 and to detachably attach theneedle burial body 20 and thehandle 30.

The holdingwings 32 are formed in a form of a pair of wings extending in an upper portion of thehandle 30 to form an acute angle in a V-shape. The operator can use fingers to hold the outer part of the V-shaped holdingwing 32 to perform the thread burial needle application.

At this time, when the angle of thegrip wing 32 is 45 ° to 46 °, the most ideal grip feeling and effective grip can be realized.

Thegrip wing 32 is made of a PE material having excellent flexibility, and can absorb slight hand vibration and exert a cushioning effect when thehandle 30 is gripped by a hand for operation.

Accordingly, the catgut embedding operation can be stably formed, the holding force is not too large, and the catgut embedding operation can be comfortably held even if the holding force is not constant, so that the fatigue of hands of an operator is reduced.

The holdingwings 32 are located in the opposite direction of the cutting inclinedsurface 12 of theneedle 10. Even if the user unintentionally holds thegrip wing 32 during the operation, the cuttinginclined surface 12 of theneedle 10 is always positioned in the direction facing the skin, which facilitates the operation.

Thehandle operation part 33 is configured to stick thethread 40 to the skin tissue after theneedle 10 inserted with thethread 40 is inserted into the human body when the thread is buried in the human body, so that the thread can be prevented from dropping together with theneedle 10 when theneedle 10 is separated.

Thehandle operation portion 33 will be described in detail with reference to fig. 2. Thehandle operation part 33 is provided at the rear side of thehandle 30, and is formed in a concave-convex shape around the entire circumference of the rear end outer circumferential surface of thehandle 30 by rotating the catgut embeddingneedle body 20 integrated with theneedle 10.

Thehandle operation part 33 enables themedical thread 40 to be firmly adhered to the inside of the human body in a state that theneedle 10 is inserted into the human body, and prevents themedical thread 40 from coming out together when theneedle 10 is pulled out from the human body.

Therefore, when thehandle operation part 33 is rotated in a state where theneedle 10 is inserted into the human body, themedical wire 40 is firmly adhered to the skin tissue, and thus themedical wire 40 is not dropped even if theneedle 10 is separated from the skin, and themedical wire 40 can be accurately positioned.

According to the above configuration, the present invention is configured to attach and detach thehandle 30 and theneedle body 20, and theneedle body 20 discarded after one use is used for hygiene, and theneedle body 20 is discarded without discarding thehandle 30 together, and thehandle 30 can be used semi-permanently, so that the operation of catgut implantation can be performed at a reduced cost.

In addition, the present invention can provide a device for injecting a drug solution by coupling thesyringe 50 when the drug solution is injected after the catgut embedding operation.

Referring to fig. 3, thehandle 30 is provided with asyringe receiving groove 34 and a medicalfluid supply passage 35.

Thesyringe accommodating groove 34 is provided in the opposite direction to the direction in which the buriedneedle body 20 is coupled, and aninlet 51 of asyringe 50 for accommodating a drug solution is inserted and accommodated.

The medicalfluid supply passage 35 is a passage for supplying medical fluid in thesyringe 50 to the buried needlemain body 20. The medicalfluid supply passage 35 is formed through thehandle 30 from the opposite end portion of the opening of thesyringe accommodation chamber 34 to the end portion of theclip portion 31.

The medicalfluid supply passage 35 is formed to have a diameter smaller than that of thesyringe housing groove 34 for supplying the medical fluid and is not caught after theinjection port 51 of thesyringe 50 is caught by a certain section.

The operation of the catgut embedding needle punch according to an embodiment of the present invention will be described below.

Fig. 4a to 4d are operation state diagrams illustrating the operation process of the needle-punching device for catgut embedding according to the embodiment of the invention.

Referring to fig. 4a, a thread to be embedded in a human body is fixed to a threadinsertion fixing hole 11.

Thethread 40 for burial, which is inserted into theneedle 10 to be fixed, is partially inserted into thethread fixing hole 11 and fixed, thereby preventing thethread 40 from being separated from thethread 40 when theneedle 10 is inserted into the skin.

Referring to fig. 4b, theneedle 10 is inserted into the human body by holding the holdingwings 32 with hands.

The hand can now hold thehandle 30 stably by means of thegripping wings 32 and can thus penetrate theneedle 10 at an angle close to horizontal to the site of application.

Therefore, the catgut embedding operation can be accurately performed on the required operation position, and the pain caused by the deeper penetration than the operation position when the operation position and theneedle 10 are inserted in a state of a large angle is reduced.

According to fig. 4c, in a state where the needle is inserted into the skin, the operator cannot view the inside, and thus the needle is inserted into other skin layers than the skin layer. To prevent this, a cuttinginclined surface 12 is formed at the end portion of theneedle 10 penetrating the skin, and theneedle 10 penetrates the inside of the skin without penetrating into the uneven portion such as the subcutaneous fat layer or the muscle layer, and passes over the uneven portion by the cuttinginclined surface 12.

At this time, the inclined cuttingsurface 12 is formed on the opposite side of the handle from which thegrip wing 32 is extended in a state where thehandle 30 and the buried needlemain body 20 are coupled.

Therefore, theneedle 10 can be prevented from being caught at the uneven portion of the skin layer other than the operation portion to cause pain during the operation or the operation of deeply applying the skin layer to be operated.

According to fig. 4d, after the completion of the catgut implantation, the needle that has penetrated into the interior of the skin is separated from the skin.

After the needle for implanting the thread is inserted into the skin, theneedle 10 is rotated inside the skin by thehandle operation part 33 and then separated from the skin so that thethread 40 is firmly adhered to the inside of the skin.

Theneedle body 20 integrated with theneedle 10 is fixed and fixed by being inserted into thehandle 30, and rotates together with thehandle 30 by rotating thehandle operation part 33 provided in thehandle 30.

Thus, when theneedle 10 is separated from the skin, thethread 40 is firmly adhered to the inside of the human body and fixed, thereby completing the thread burial needle.

Fig. 5 is a view showing a state in which a syringe is coupled to a needle-penetrator for catgut embedding and a medicine is injected, according to an embodiment of the present invention.

Referring to fig. 5, after the completion of the catgut implantation procedure, a liquid medicine is additionally injected to further improve the therapeutic effect before the needle is separated from the skin.

For this purpose, asyringe 50 containing a medicinal solution is coupled to thesyringe storage groove 34 provided in thehandle 30, and the medicinal solution is injected into the skin of the embeddedthread 40.

At this time, the medical fluid is discharged from thesyringe 50 and injected into the needleburial needle body 20 through the medicalfluid supply path 35, and the needleburial needle body 20 is formed to be hollow inside and integrated with theneedle 10, and the medical fluid flows to theneedle 10 side through the needleburial needle body 20. Then, the drug solution is discharged to the side of thethread 40 embedded in the skin through thethread fixing hole 11 formed through the inside of theneedle 10, and the drug solution is directly filled into thethread 40 embedded in the skin.

As described above, when the medical thread is embedded in the human body, pain occurring during the operation can be reduced, and fatigue of the hand can be reduced even when the thread embedding needle is operated for a long time in a large amount.

Therefore, even if the holding power of the operator is not constant, the operation can be stably and accurately performed, and the thread burial needle body and the handle can be separated.

Accordingly, the cost waste caused by discarding the thread burial needle body and the handle after one-time use can be reduced.

In general, a thread and a needle for implanting thread having different lengths are used depending on the site to be operated and the purpose of operation, and the needle body for implanting thread having different lengths and different shapes can be easily replaced and used by attaching and detaching the handle and the needle body for implanting thread as needed.

Thus, the operation can be performed effectively according to the operation site and the purpose of the operation.
