Description

  The present invention relates to an acupuncture needle.

In acupuncture, the practitioner inserts an acupuncture needle (an acupuncture needle) into the patient by the following procedure.
In the case of the tube needle method, when the needle is inserted into the needle tube, the acupuncture needle is placed on the acupuncture point, and the tip of the needle is advanced from the skin surface into the subcutaneous tissue by the action of cutting, and then the needle tube is removed. In this case, the needle is supported with the left hand (presser) and the skin where the needle tip is inserted is pushed open, and the insertion is advanced with the right hand (singer).

  At this time, the thumb and index finger of the pusher touch the needle body. When inserting a disposable acupuncture needle for the first time, touching the needle body in this way risks risking contamination of the acupuncture needle with human proteins (shards of skin) and microorganisms attached to the finger. In the case of insertion after the second time, in addition to this, there is a risk that the operator's finger touches the needle part once entering the patient's body.

Therefore, it is an action that the operator's finger directly touches the needle body when inserting the acupuncture needle for safety against the operator and the patient. However, in practice, it is difficult to insert the needle accurately without adding a pusher.
Therefore, as a safety measure, Patent Document 1 describes that an outer cylinder (microtube) having a shorter length in the longitudinal direction than the needle body is attached to the needle tip side of the needle body in the needle needle. Yes. The outer cylinder can be smoothly moved from the needle tip side to the rear end side of the needle body at the time of insertion. By attaching a pusher through the outer cylinder when the practitioner inserts, the practitioner's finger can be prevented from touching the needle body.
JP 2006-026341 A

  However, in the acupuncture needle equipped with the outer cylinder described in Patent Document 1, a predetermined insertion depth (that is, when the length from the distal end of the needle handle to the skin matches the length in the longitudinal direction of the outer cylinder) ), One end of the outer cylinder comes into contact with the patient's skin and the other end comes into contact with the needle handle at the distal end of the needle handle, so that the outer cylinder serves as a stopper. The above insertion cannot be performed. Therefore, when the penetration depth desired by the practitioner exceeds the predetermined penetration depth, there is a problem that the penetration depth desired by the practitioner cannot be ensured.

  The present invention has been made in view of such a problem, and an object thereof is to provide an acupuncture needle that can ensure a desired insertion depth while preventing a practitioner from contacting the needle body.

  Therefore, in the present invention, a needle body having a needle tip formed at the tip, a cylindrical needle handle provided so as to cover the rear end side of the needle body, and a fixing portion for fixing the needle body and the needle handle And a tubular body that covers at least a part of the outer peripheral surface of the needle body exposed to the front end side from the end portion on the front end side of the needle handle and is slidably mounted on the outer peripheral surface of the needle body. Further, the fixing portion is arranged at a predetermined position on the rear end side from the distal end side end portion of the needle handle, and the inner diameter of the needle handle is made larger than the outer diameter of the tubular body from the fixing portion to the distal end side.

  Further, in the present invention, a needle body having a needle tip formed at the tip, a cylindrical needle handle provided so as to cover the rear end side of the needle body, and a fixing portion for fixing the needle body and the needle handle; A tubular body that is slidable with respect to the outer peripheral surface of the needle body is mounted and used. The fixing portion is disposed at a predetermined position on the rear end side from the tip side end portion of the needle handle, and an annular space is formed between the outer peripheral surface of the needle body and the inner peripheral surface of the needle handle on the tip side from the fixing portion. The rear end side of the tubular body can be accommodated in this annular space.

  According to the present invention, when inserting, the rear end side of the tubular body corresponding to the outer cylinder can be accommodated in the annular space formed between the outer peripheral surface of the needle body and the inner peripheral surface of the needle handle. Therefore, the insertion depth set by the practitioner can be made deeper than in the case where the fixing portion is disposed at the distal end side end portion of the needle handle.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a configuration diagram of an acupuncture needle according to a first embodiment of the present invention.
The scissors needle 1 fixes a needle body 2 having a needle tip 2a formed at the tip thereof, a cylindrical needle handle 3 provided on the rear end side of the needle body 2, and the needle body 2 and the needle handle 3. The fixing portion 4 is configured to include a tube (tubular body) 5 provided in the exposed portion 2 b of the needle body 2. In addition, in this embodiment, the fixing | fixed part 4 is arrange | positioned at the rear-end side edge part 3b of the needle handle 3. FIG.

Here, the exposed portion 2b of the needle body 2 refers to the outer peripheral surface of the needle body 2 from the distal end side end portion 3a of the needle handle 3 to the distal end (needle tip portion 2a) of the needle body 2.
In order to prevent the operator's finger from touching the exposed portion 2 b of the needle body 2, a tube 5 slidable with respect to the outer peripheral surface of the needle body 2 covers a part of the exposed portion 2 b of the needle body 2. . In the present embodiment, the tube 5 is made of resin, but other materials such as rubber and metal may be used.

On the other hand, the needle handle 3 is made of metal, and the fixing portion 4 fixes the needle body 2 and the needle handle 3 using soldering, laser welding, ultrasonic welding, or the like. Although not shown, in this embodiment, the material of the needle handle 3 is a metal, and the needle handle 3 can be pressed from the outside to the inside (that is, crimped) to form the fixed portion 4. is there.
In the present embodiment, the needle body 3 may be made of resin, and the fixing portion 4 may be adhesively fixed to the needle body 2 and the needle handle 3 by using an adhesive. Moreover, the material of the needle handle 3 may be resin, and the needle handle 3 and the fixed part 4 may be formed integrally. As an example of this, it is conceivable to form the needle handle 3 (and the fixing portion 4) by using insert molding, after the needle body 2 is loaded in the mold, and then injecting resin into the mold.

Furthermore, as the cylindrical needle handle 3, in addition to the illustrated one, a covered cylindrical shape having a lid portion at the rear end side end portion of the needle handle 3 may be used.
Further, the diameter (inner diameter) D <b> 1 of the inner peripheral surface of the cylindrical needle handle 3 is made larger than the diameter (outer diameter) D <b> 2 of the outer peripheral surface of the tube 5 on the distal end side from the fixed portion 4. For this reason, the rear end side of the tube 5 can be accommodated in an annular space formed between the outer peripheral surface of the needle body 2 and the inner peripheral surface of the needle handle 3 on the front end side of the fixing portion 4.

Further, since the fixing portion 4 is disposed at the rear end side end portion 3b of the needle handle 3, the annular space is maximized, and the slidable range of the tube 5 with respect to the needle body 2 is maximized.

2A shows a method of filling the medical lubricant 6 between the inner peripheral surface of the tube (tubular body) 5 and the outer peripheral surface of the needle body 2. In this method, the tube 5 can be slid smoothly with respect to the outer peripheral surface of the needle body 2 by an external force. However, when no external force is applied, the tube 5 remains stationary with respect to the outer peripheral surface of the needle body 2. Hold. A medical silicone oil or the like is used as a medical lubricant.

  FIG. 2B shows that when the material of the tube 5 is resin, rubber, or the like (that is, when the tube 5 is molded by a flexible member), the cross-sectional shape of the inner peripheral surface of the tube 5 is elliptical (flat). The shape) method is shown. In this method, the tube 5 first has the shortest distance L1 between the facing surfaces on the inner peripheral surface of the tube 5 smaller than the outer diameter D3 of the needle body 2, and the longest distance L2 between the facing surfaces on the inner peripheral surface of the tube 5 is the needle. It shape | molds previously so that it may become larger than the outer diameter D3 of the body 2 ((1) of (B) of FIG. 2). Next, the tube 5 is attached to the outer peripheral surface of the needle body 2. Thereby, the shortest distance between the facing surfaces on the inner peripheral surface of the tube 5 becomes the outer diameter D3 of the needle body 2 ((2) in FIG. 2B). Therefore, the tube 5 has a restoring force that attempts to return the shortest distance between the facing surfaces on the inner peripheral surface of the tube 5 to the initial shortest distance L1 from the outer diameter D3 of the needle body 2. Due to the restoring force, the tube 5 remains stationary with respect to the outer peripheral surface of the needle body 2 when no external force is applied.

  FIG. 2C shows a flat polygonal cross-sectional shape of the inner peripheral surface of the tube 5 when the material of the tube 5 is resin, rubber, or the like (that is, when the tube 5 is molded by a flexible member). The method is shown. In this method, the tube 5 first has the shortest distance L4 between the facing surfaces on the inner peripheral surface of the tube 5 smaller than the outer diameter D3 of the needle body 2, and the longest distance L5 between the facing surfaces on the inner peripheral surface of the tube 5 is the needle. It shape | molds previously so that it may become larger than the outer diameter D3 of the body 2 ((1) of (C) of FIG. 2). Next, the tube 5 is attached to the outer peripheral surface of the needle body 2. Thereby, the shortest distance between the facing surfaces on the inner peripheral surface of the tube 5 becomes the outer diameter D3 of the needle body 2 ((2) in FIG. 2C). Therefore, the tube 5 has a restoring force that attempts to return the shortest distance between the facing surfaces on the inner peripheral surface of the tube 5 from the outer diameter D3 of the needle body 2 to the initial shortest distance L4. Due to the restoring force, the tube 5 remains stationary with respect to the outer peripheral surface of the needle body 2 when no external force is applied.

In addition to the cross-sectional shape of the inner peripheral surface of the tube 5 shown in FIGS. 2B and 2C, the flat shape may be an oval shape.
FIG. 3 shows a method in which the central axis in the longitudinal direction of the tube 5 is previously curved when the material of the tube 5 is resin, rubber, or the like (that is, when the tube 5 is molded by a flexible member). Yes. In this method, the tube 5 is first formed so that the central axis in the longitudinal direction of the tube 5 is a curve ((A) in FIG. 3). Next, the tube 5 is attached to the outer peripheral surface of the needle body 2 ((B) of FIG. 3). At this time, the curvature of the central axis in the longitudinal direction of the tube 5 decreases, and a restoring force is generated in the tube 5 by approaching the central axis in the longitudinal direction of the needle body 2 that is substantially straight. Due to the restoring force, the tube 5 remains stationary with respect to the outer peripheral surface of the needle body 2 when no external force is applied.

  FIG. 4 shows a method of using the tube 5 having a closed portion at one end when the material of the tube 5 is resin or rubber. First, the tube 5 is formed so that one end of the tube 5 is a closed portion and the other end is an opening to which the needle body 2 can be attached, and the tube 5 is attached to the outer peripheral surface of the needle body 2. ((A) of FIG. 4). Next, the penetrating portion 5a is formed by piercing the needle tip portion 2a of the needle body 2 into the closed portion of the tube 5 ((B) of FIG. 4). By bringing the tube 5 and the outer peripheral surface of the needle body 2 into contact with each other through the penetrating portion 5a, the tube 5 remains stationary with respect to the outer peripheral surface of the needle body 2 when no external force is applied. The timing for forming the penetrating portion 5a by piercing the needle tip portion 2a of the needle body 2 into the closed portion of the tube 5 is not only in the process of manufacturing the needle 1, but also immediately before the practitioner uses the needle 1 or described later. It may be at the time of cutting.

Therefore, by using at least one method of attaching the tube 5 to the outer peripheral surface of the needle body 2 shown in FIGS. 2 to 4, the tube 5 is prevented from easily falling off from the outer peripheral surface of the needle body 2. Can do.
