Description

  The present invention relates to an improvement in the needle shape of a suture needle with a needle, particularly a cosmetic surgery, for example, a suture thread with a needle suitable for plication surgery.

  2. Description of the Related Art Conventionally, a method of burying heavy iron for forming heavy iron, for example, double iron is widely known. In this burial method, the upper epidermis and the skin plate in the skin tissue are sewn together with a suture, and the epidermis part pulled to the side of the skin by this suture is buried inside and lined, For example, a double fold is formed.

  FIG. 3 is a diagram showing a process example of a conventional heavy padding method.

  Generally, a double-ended needle-attached suture in which needles are fixed to both ends of the suture is used in the double burial method. In order to reduce tissue damage, a round needle having a circular cross section is used as the needle, and the proximal end side of the round needle is formed flat so as to be held by a needle holder. For example, when performing double scissors treatment, the suture point (the insertion point) is determined by the design of the double scissors, and as shown in FIGS. 3A and 3B, the suture points A and B are provided on the skin side and the scalp side. Mark. After the local anesthesia, as shown in FIG. 3 (A), after the operation, in order to embed the suture thread and the ligature portion subcutaneously, the suture point A is incised 1 to 2 mm with a scalpel 30 and further expanded with a detailed scissors or the like. An incision 32 is formed. Next, as shown in FIG. 3 (B), the eyelid is inverted, the corneal protection plate 34 is inserted between the eyelid and the eyeball, and one of the round needles 40 of the suture thread 38 with both ends is held by the needle holder 36. The pinching part 40a is pinched, and the round needle 40 is pierced from the stitching point A on the side of the base plate to the stitching point A on the skin side. Similarly, the other round needle 42 is pierced from the suture point B on the side of the base plate to the suture point B on the skin side (FIG. 3C). FIG. 3D shows a state in which the suture thread 44 has passed through the sewing points A and B. FIG. Next, the round needle 42 is passed through the shallow skin from the outer skin from the stitching point B, and is pierced through the stitching point A (FIG. 3E). Thereafter, the suture thread 44 is cut at an appropriate length indicated by a dotted line, and the round needles 40 and 42 are removed (FIG. 3F). The bougie 46 is placed at the stitching point A, tied 3 to 4 times, and separated from the ligature 48 leaving about 1 mm (FIG. 3G). The ligation part 48 is embedded in the incision part 32, and the treatment is finished (FIG. 3 (H)).

  As described above, in the above-described heavy cage embedding method, the incision portion 32 must be formed in advance with a scalpel and a scissors in order to embed the suture 44 and the ligation portion 48 under the skin after the operation. That is, there is a problem that an operation of incision with a scalpel or the like is required before suturing, and the operation work of the heavy burial method is complicated.

  Moreover, the flatness ratio of the width with respect to the thickness of the pinching portions 40a and 42a of the round needle is generally 1: 1.8 to 2.0. Therefore, the tissue cannot be pushed out to a size corresponding to the incision portion 32 with the flat clamping portion at the time of piercing.

  Accordingly, the present invention has been made to solve the above-described problems, and provides a suture thread with a needle that can embed a suture thread and a ligation portion of a suture thread without requiring an incision with a scalpel or the like. With the goal.

The suture with a needle according to the present invention is a suture with a needle in which a round needle is fixed to one end or both ends of the suture, and the maximum flatness ratio of the thickness and width of the holding portion of at least one round needle is 1: 3. .5 to 4.0.
The suture needle with a needle according to the present invention is a suture with a needle that is used in a method of burying a chisel to form a chisel, and has a round needle fixed to one or both ends of the suture. The diameter of the round needle is 0.3 to 0.7 mm, and the clamping portion formed by flattening the proximal end side of the round needle gradually increases the flatness ratio of the width with respect to the thickness of the clamping portion. The ridge line is formed in a taper shape so that the tissue can be gradually expanded at the time of puncture, and the maximum flatness ratio of the thickness and width of the pinching portion of the round needle is 1: 3.5 to 4.0. The width of the piercing hole expanded by the width of the holding portion having a ratio has a width for embedding the ligation portion of the suture thread.
The needle of the present invention is a needle in which a suture is fixed to a proximal end portion, and has a maximum flatness ratio of the thickness and width of a holding portion of the needle of 1: 3.5 to 4.0. .
Further, the needle of the present invention is a needle used in a heavy padding method for forming a heavy pad, and a suture is fixed to a proximal end part, and the diameter of at least one needle is 0.3 to The pinching portion formed by flattening the proximal end side of the needle is 0.7 mm, and the flattening ratio of the width with respect to the thickness of the pinching portion gradually increases, and the ridge line gradually pushes the tissue during piercing. It is formed in a taper shape so as to be spread, and the maximum flatness ratio of the thickness and width of the pinching portion of the needle is 1: 3.5 to 4.0, and is pushed and widened by the width of the pinching portion having the maximum flatness ratio The width of the piercing hole is characterized by having a width for embedding the ligation portion of the suture thread.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments (hereinafter referred to as embodiments) of the invention will be described with reference to the drawings.

  In the present embodiment, a double-ended needle-attached suture in which round needles are fixed to both ends of the suture will be described. FIG. 1 is a diagram illustrating the overall configuration of a suture with double-ended needles according to the present embodiment.

  As shown in FIG. 1, the suture thread 1 with double-ended needles of the present embodiment includes a suture thread 10 and round needles 12 and 14 fixed to both ends of the suture thread 10.

  The suture thread 10 is made of nylon, for example, and has a length of about 25 cm to 40 cm. For example, the distal end of the suture thread 10 is inserted into a caulking hole at the base end portion of the round needles 12 and 14 and subjected to caulking processing, and the round needles 12 and 14 are fixed to both ends of the suture thread 10.

  The round needles 12 and 14 are made of, for example, stainless steel, have a length of about 15 to 25 mm, are formed in a circular cross section to reduce tissue damage, and have a diameter of 0.3 to 0.7 mm. In addition, the round needle of the present invention includes a round needle (tip pyramid shape) in which the tip portion of the round needle is formed into a flat surface, for example, a triangular shape in which the tip portion of the round needle is cut into three planes every 120 ° about the axis center A round needle with a (triangular pyramid shape) is also included. When the skin tissue is hard, it is better to use a round needle processed in this way.

  Further, the round needles 12 and 14 are formed in a curved shape so as to be suitable for a surgical operation. For example, as described in the background art, when the curvature is large in the process from the stitching point B to the stitching point A in FIG. If the curvature is small, the round needle that has passed through the skin may protrude to a point farther from the stitching point A. Accordingly, the length and the curved shape of the round needles 12 and 14 are selected depending on the distance between the stitch points A and B. It should be noted that the round needles 12 and 14 are not evenly curved, and gradually become smaller from the proximal end portion to the distal end portion of the needle. The curvature of the tip is preferably R3 / 8 to R1 / 2. According to this shape, there is an advantage that the suture points A and B on the skin side can be easily pierced from the suture points A and B on the side of the base plate.

  A characteristic point in this embodiment is that a part of at least one round needle of the suture with a double-ended needle is flattened, and preferably the maximum flatness of the width with respect to the thickness of the pinching portion held by the needle holder The ratio is 1: 3.5 to 4.0. Thereby, at the time of puncture of a round needle, a tissue can be spread and a suture thread and a ligation part can be buried after a treatment.

  2A and 2B are enlarged views of the round needle 12. FIG. 2A is a plan view, FIG. 2B is a front view, and FIG. 2C is a cross-sectional view taken along line AA in FIG. FIG.

  As shown in FIG. 2, a clamping portion 12 b is formed on the proximal end side of the round needle 12. In this embodiment, the clamping part 12b is formed in the cross-sectional flat shape, and the cutting edge is not formed in the ridgeline 12c of the clamping part 12b so that a structure | tissue may not be cut. Further, as shown in FIG. 2B, the ridge line 12c of the sandwiching portion 12b forms a gentle taper so as to gradually expand the tissue during piercing, and the flatness ratio of the width w to the thickness t gradually increases. It is configured to be large. The maximum flatness ratio is formed on the proximal end side at the end of the tapered shape. This maximum flatness ratio is preferably set such that it does not refract at the time of piercing and can expand the tissue to embed the ligature. In the present embodiment, the maximum flatness ratio of the width w with respect to the thickness t is in the range of 1: 3.5 to 4.0. Specifically, when the diameter of the round needle 12 is 0.55 mm, the thickness t is 0.25 to 0.35 mm, and the width w is 0.9 mm to 1.0 mm. Thereby, the tissue can be expanded when the round needle 12 is pierced, that is, the piercing hole can be expanded. In the present embodiment, the flat wide surface is formed in a direction perpendicular to the radius of curvature. Thereby, clamping by the needle holder 36 at the time of a treatment becomes easy, and workability | operativity can be improved.

  Next, the operation of the double burial method using the suture thread 1 with both ends of the present embodiment will be briefly described.

  The double-ended needle-attached suture thread 1 can be used for the operation of the heavy burial method described in the background art. A characteristic point is that, when the suture thread 1 with double-ended needles of the present embodiment is used, it is not necessary to incise the suture point A with a scalpel or a scissors after marking the suture points A and B. That is, after marking the suture points A and B, the round needle 12 of the suture thread 1 with double-ended needles is pierced from the suture point A on the base plate side to the suture point A on the skin side. Since the pinching portion 12b of the round needle 12 is configured such that the maximum flatness ratio of the width w to the thickness t is 1: 3.5 to 4.0, the tissue can be expanded during piercing. Thereby, after the treatment, the suture thread 10 and the ligated portion of the suture thread 10 can be easily embedded in the tissue once pushed and spread. In addition, the other piercing process of the heavy iron burying method can be performed similarly to the past.

  Note that the operation of the heavy burial embedding method described in this specification is an example, and the suture with a double-ended needle of this embodiment is suitably used in various variations of the heavy burial embedding method in which the heavy burial is formed by suturing. Can be applied.

  In the present embodiment, the holding portion of one round needle of the double-ended needle-attached suture thread 1 is configured to have a predetermined maximum flatness ratio, but both the round needles may have the same shape.

  Furthermore, it is also preferable that the holding part of the round needle of the single-needle suture thread having a round needle fixed to one end of the suture thread has a predetermined maximum flatness ratio. This single needle-attached suture can also be used in the heavy padding method described in the background art. In this case, in the step corresponding to FIGS. 3B and 3C, at the time of initial puncture, the suture point A on the skin side is pierced from the suture point A on the mortar plate side, and then the suture point B on the mortar plate side. It suffices to sequentially pierce the suture point B on the skin side.

It is a figure which shows the whole structure of the suture thread with both ends needle | hook of embodiment. 2A is an enlarged view of the round needle 12, FIG. 2A is a plan view, FIG. 2B is a front view, and FIG. 2C is a cross-sectional view taken along line AA of FIG. It is a figure which shows the process example of the conventional heavy burial method.
