Each embodiment of the speech disorder treatment tool of the present invention will be described below with reference to the drawings.

First, the first embodiment of the present invention will be described.

As shown in Figures 1 and 2, the voice disorder treatment tool (hereinafter referred to as "the treatment tool") 6 according to the first embodiment of the present invention has a front piece 1b and a back piece 1c, and includes: The thyroid cartilage 11 shown in Fig. 3 has a plurality of (in this embodiment, a pair) clamping parts 1, 1, and a plurality of clamping parts in which the cutting ends 12, 12 facing each other are fitted. 1. The bridging section of 1.

The front sheet 1b is formed in a substantially short strip shape in plan view. The base end side of the front sheet 1b in the longitudinal direction x is bent and formed with an end surface portion 1a to which the cut end surface 12a of the thyroid cartilage 11 shown in FIG. 3 abuts. On the front end side of the end surface portion 1a of the front sheet 1b, a surface contact portion 1d to which the front surface 11a of the thyroid cartilage 11 abuts is formed.

In the front sheet 1b, a plurality of holes 3 (two holes in this embodiment) are formed at intervals in the longitudinal direction x.

These holes 3 and 3 are formed so that a suture thread (not shown in the figure, the same applies hereinafter) can pass through, and the suture needle can pass through to have a size of 1.0 mm to 2.0 mm.

The front sheet 1b, as shown in FIG. 2, has a deformable bending area 15 centered on an imaginary line K extending in the width direction y of the front sheet 1b. The setting position of the imaginary line K is determined in accordance with the shape of the cut end 12 of each patient in such a way that it can be closely attached to the cut end 12 of the patient (please refer to FIG. 3). The range set as the virtual line K is the bending area 15. Specifically, the bending area 15 is generally set in a range of 1.0 mm to 6.0 mm from the base end of the surface contact portion 1d.

In this embodiment, the bending region 15 has a reinforcing structure S formed by implementing the hole 3 to extend in a direction intersecting the width direction y, that is, implementing the elongated hole 3 extending substantially in the longitudinal direction x .

Specifically, the hole 3 is formed in an oval shape. In addition, the elongated hole 3 is not limited to the elliptical shape, as long as it has a portion that is formed as parallel to the side edge 20 of the front sheet 1b as possible, in other words, as long as it is a perfect circle than the hole 3 It may be formed to be longer in the longitudinal direction x, or it may be substantially rectangular, or as shown in Fig. 4, the long sides may be parallel to each other and the short sides may be embodied in a semicircular shape. In addition, when the hole 3 is formed as shown in FIG. 4, a concave portion 9 (illustrated by a two-dot dashed line in the same figure) for tying and fixing the suture may be formed.

As shown in Figs. 1 and 3, the back sheet 1c is a portion bent from the end face 1a of the front sheet 1b toward the rear face 11b side of the thyroid cartilage 11 shown in Fig. 3.

The front sheet 1b and the rear sheet 1c are integrally formed to constitute a clamping part 1, and the clamping part 1 is formed in a substantially J-shape (inverted J-shape) as a whole.

In the clamping part 1, the length of the front sheet 1b is sufficient as long as it has a length necessary to clamp the thyroid cartilage 11 along the shape of the thyroid cartilage. Specifically, it is set to be about 8mm~12mm. good. Furthermore, the length of the back sheet 1c is preferably a length from the end edge of the cut end 12 of the thyroid cartilage 11 to the end edge of the soft tissue 40 located below the thyroid cartilage 11, specifically It is preferably about 1.5mm~5.5mm.

As shown in Figs. 1 to 3, the gripping portion 1 has a front sheet 1b arranged on the front surface 11a side and a cut end surface 12a of the thyroid cartilage 11, and its rear sheet 1c is arranged on the back surface of the thyroid cartilage 11 The 11b side is arranged symmetrically on the side 11b so as to be fitted with the cut ends 12 and 12 of the thyroid cartilage 11 facing each other, and is connected by the bridging part 2.

The bridging part 2 is a part for connecting the clamping part 1, and connects the clamping part 1 in the middle part of the extension direction of the end surface part 1a. The length (d) of the bridging part 2, that is, the distance D between the two clamping parts 1, 1 is equivalent to the distance between the cut ends 12, 12 of the thyroid cartilage 11 after expansion. Symptoms, body shape, and vocal state of patients with phonation disorders are different, but it is generally set in the range of 2mm~6mm.

The clamping part 1 and the bridging part 2 are both made of titanium.

The titanium metal used in the present invention is not limited to pure titanium metal, and may include titanium alloys that are also used in artificial bones, artificial joints, and artificial tooth roots as metal materials for living organisms. Specifically, as long as it does not contain nickel (Ni), which is indicated as a cause of carcinogenicity or allergies, Ti-6Al-4V, etc., a titanium alloy known for its excellent adaptability to the living body, can be used. Titanium or titanium alloy, in order to prevent its wear or dissociation, you can also use nitrogen (N) or carbon (C) ion implantation to modify the surface, or anodize to give the desired color .

The distance between the surface contact portion 1d and the back sheet 1c shown in Figure 1 (the width dimension of the end face portion 1a) t is preferably slightly larger than the thickness dimension of the thyroid cartilage 11. Specifically, it is approximately 2 mm to 4 mm good. If the interval t is smaller than the thickness dimension of the thyroid cartilage 11 shown in Fig. 3, and the thyroid cartilage 11 is tightened, the gripping portion 1 will continue to press the thyroid cartilage 11 for a long period of time, which may cause the thyroid cartilage 11 11. The risk of wear or damage. On the other hand, if the distance t between the surface abutting portion 1d and the back sheet 1c is too large compared to the thickness of the thyroid cartilage 11, it is substantially difficult to clamp the thyroid cartilage 11. This is the difference between the clamping portion 1 and the thyroid cartilage 11 The thyroid cartilage 11 tends to cause relative positional deviation (sliding).

Next, the method of using the treatment tool 6 of the present invention will be described with reference to Figs. 1 to 3.

First, the middle portion of the thyroid cartilage 11 is incised, and the distance between the cut ends 12 and 12 that can produce sound is determined. After deciding the interval to expand, select the treatment tool 6 with the length d of the bridge 2 that matches the interval, so that the surface abutment portion 1d can contact the front face 11a of the thyroid cartilage 11, and the front piece 1b is bent The area 15 deforms the front sheet 1b as needed. Then, the clamping portion 1 is fitted to the cut end 12 such that the front sheet 1b contacts the front face 11a and the cut end face 12a of the thyroid cartilage 11 and the back face sheet 1c contacts the rear face 11b of the thyroid cartilage 11.

The treatment tool 6 is attached so that the clamping part 1 clamps only the thyroid cartilage 11, and the front end of the back sheet 1c is inserted between the thyroid cartilage 11 and the soft tissue 40 below it. In the treatment tool 6 of the present invention, since the back sheet 1c is formed of a titanium thin plate, the front end of the back sheet 1c can be inserted between the thyroid cartilage 11 and the soft tissue 40 relatively easily.

Since the distance t between the surface abutting portion 1d of the clamping portion 1 and the back sheet 1c is formed slightly larger than the thickness of the cartilage to be clamped, in order to fix the treatment tool 6 more firmly, the thread is passed through and close to The hole 3 of the end face 1a is preferably sutured to fix the gripping part 1 and the thyroid cartilage 11. In addition, if necessary, the thyroid cartilage 11 can be reinforced and sutured with the thread passing through the hole 3 on the front end side in the longitudinal direction x. Such suture operation can be performed by setting the clamping portion 1 of the treatment tool 6 to the cut end 12 of the thyroid cartilage 11 and temporarily fixing it, so it can be compared with the conventional silicone block. Proceed calmly.

Although the treatment tool 6 of the present invention can be installed at an appropriate position of the cutting end 12 as long as it can maintain the incision position of the thyroid cartilage 11, it can also be installed at two of the lower part and the upper part of the thyroid cartilage 11. position.

As implemented in the above manner, the treatment tool 6 installed in the thyroid cartilage 11 of the patient has the hole 3 formed in the bending area 15 formed as a long hole extending in the longitudinal direction x, so that the action of the thyroid cartilage 11 can be dispersed. The elastic restoring force in the closing direction or the stress applied to the plate portion around the hole 3 due to the vibration during sound and swallowing can prevent stress concentration.

Therefore, the effect of effectively preventing the previous face sheet 1b from breaking due to stress concentration in the bending area 15 can be achieved.

Next, the second embodiment of the present invention will be described using FIG. 5. In this embodiment, the description will be centered on the configuration that is different from the first embodiment, and the same configuration as the first embodiment will be denoted by the same reference numerals, and the description will be omitted.

The treatment tool 6 of the second embodiment constitutes the reinforcing structure S by bending the side edge 20 of the front sheet 1b to match the shape of the opening edge 3a of the hole 3.

Specifically, the shape of the side edge 20 of the front sheet 1b is substantially along the shape of the hole 3 formed in the bending area 15 and is formed in a smoothly curved and protruding manner outside the width direction y.

By forming the front sheet 1b in this way, the width P of the plate around the hole 3 formed in the bending area 15 is ensured. Therefore, in the bending area 15, the elastic restoring force acting in the closing direction by the thyroid cartilage 11 or the stress applied to the plate around the hole 3 by the vibration during vocalization and swallowing can be dispersed, and stress concentration can be prevented. .

Therefore, the effect of effectively preventing the previous face sheet 1b from breaking due to stress concentration in the bending area 15 can be achieved.

Next, the third embodiment of the present invention will be described using FIG. 6. In this embodiment, the description will be centered on the configuration that is different from the first embodiment, and the same configuration as the first embodiment will be denoted by the same reference numerals, and the description will be omitted.

In this embodiment, the description will be centered on the configuration that is different from the first embodiment, and the same configuration as the first embodiment will be denoted by the same reference numerals, and the description will be omitted.

The treatment tool 6 of the fifth embodiment constitutes a reinforcing structure S by providing concave strips 35, 35 capable of tying and fixing sutures on the plate surfaces 32, 32 of the front sheet 1b.

Specifically, the treatment tool 6 of the fifth embodiment is not formed in the bending area 15: it is caused by the vibration of the thyroid cartilage 11 or the stress caused by the elastic restoring force of the thyroid cartilage 11 acting in the closing direction. The hole 3 that breaks the front sheet 1b is formed with a groove 35 on at least one plate surface 32 of the front sheet 1b for tying and fixing the suture thread.

The groove 35 may have any cross-sectional shape as long as the stress is hard to concentrate, but it is preferably a shape such as a rectangular cross-section where the stress is hard to concentrate.

The treatment tool 6 has a width dimension of the front sheet 1b that can withstand the stress caused by the vibration of the thyroid cartilage 11 or the elastic restoring force of the thyroid cartilage 11 in the closing direction. In addition, the concave strip 35 has a cross-sectional shape in which stress is hard to concentrate. This constitutes the reinforcing structure S. Therefore, it is possible to achieve the effect of effectively preventing the front sheet 1b from breaking at the same time as the ligation fixing portion formed with the suture thread.
