Description

本願発明は、口腔外科領域において手術の際に用いられ、患者の口腔を開けた状態を維持する為の口腔開口維持装置に関するものである。 The present invention relates to an oral opening maintenance device used at the time of surgery in the field of oral surgery and for maintaining an open state of a patient's oral cavity.

口腔外科領域における全身麻酔下での手術は、口腔内に疾患がある場合、口を開いた状態を手術中に保持して行うことが一般的である。また、狭い口腔内の手術では繊細な操作が求められるため手術操作に伴い術野が動かないよう術中は頭頸部を固定する必要がある。現在、口腔外科領域の手術においては、手術中に患者の口腔を開けた状態で頭頸部を保持または固定する機器はなく、人手に頼るしかないという現状がある。 Surgery under general anesthesia in the field of oral surgery is generally performed by keeping the mouth open during surgery when there is a disease in the oral cavity. In addition, since delicate operation is required in the operation in the narrow oral cavity, it is necessary to fix the head and neck during the operation so that the surgical field does not move with the operation. Currently, in surgery in the field of oral surgery, there is no device for holding or fixing the head and neck with the patient's mouth open during surgery, and the current situation is that there is no choice but to rely on human hands.

日本において厚生労働省が行った平成２５年度の医療施設調査において、日本国内には８０００近くの病院が存在する中、口腔外科を併設している病院は約１８％である１１００程度と非常に少ない。さらに大学病院の口腔外科を除けば、その医局員は２〜３人と非常に少数で診療を行っている施設が多い。そして、全身麻酔下での手術においては、執刀医の他に補助を含めて２〜３人で行うことが多く、そのため手術を行っている最中はほとんどの場合、外来診療を止めて行うのが現状である。 According to a 2013 medical facility survey conducted by the Ministry of Health, Labor and Welfare in Japan, there are nearly 8,000 hospitals in Japan, but the number of hospitals with oral surgery is very small, about 1100, which is about 18%. Furthermore, except for the oral surgery of university hospitals, there are many facilities where the number of medical staff is very small, which is very small. And, in the operation under general anesthesia, it is often performed by 2 to 3 people including the assistant in addition to the surgeon, so in most cases during the operation, the outpatient clinic is stopped. Is the current situation.

そこで、人手に頼ることなく安全かつ確実に患者の口腔を開いた状態を維持する器具を開発することは、手術に必要な人数の削減につながり、手術中でも外来診療や入院患者の対応などをすることが可能となる。そのため医師や患者に必要とされる口腔外科専用の口腔開口維持装置が求められている。
従来から歯科用の口腔開口補助具として、特許文献１、特許文献２、特許文献３が知られている。
また、特許文献４には、歯科用器具を所定の位置及び所定の姿勢に設定可能とする歯科用器具保持装置が開示されている。 Therefore, developing a device that keeps the patient's oral cavity open safely and reliably without relying on human hands will lead to a reduction in the number of people required for surgery, and will provide outpatient treatment and inpatient care even during surgery. It becomes possible. Therefore, there is a demand for an oral opening maintenance device dedicated to oral surgery required by doctors and patients.
Patent Document 1, Patent Document 2, and Patent Document 3 have been conventionally known as dental oral opening aids.
Further, Patent Document 4 discloses a dental instrument holding device capable of setting a dental instrument in a predetermined position and a predetermined posture.

本願発明の口腔開口維持装置の構成について、図１（ａ）（ｂ）に基づいて、説明する。図１（ａ）は、複数の処置器具１として、筋鈎、へら、ホックが、支持部５に装着されている。支持部５は、患者の頭部を囲むＵ字状の枠で２分割されており、中央部にて矢印Ａに示す様に左右にスライドさせることによって、患者に応じて口腔開口維持装置の幅を変えることができる。尚、支持部５は、必ずしも左右両側に設ける必要はなく、施術に応じて片側だけでも構わないし、Ｕ字状の全体が一つの部材であっても構わない。 The configuration of the oral opening maintenance device of the present invention will be described with reference to FIGS. 1 (a) and 1 (b). In FIG. 1A, a muscle hook, a spatula, and a hook are attached to the support portion 5 as a plurality of treatment instruments 1. The support portion 5 is divided into two by a U-shaped frame surrounding the patient's head, and by sliding the support portion 5 left and right as shown by arrow A at the central portion, the width of the oral opening maintenance device is adjusted according to the patient. Can be changed. The support portions 5 do not necessarily have to be provided on both the left and right sides, and may be provided on only one side depending on the treatment, or the entire U-shape may be a single member.

図１（ｂ）は、図１（ａ）の一部の拡大図である。処置器具１であるホックは、その基端側が、着脱自在な手段によって引っ張り棒２に繋がり、引っ張り棒２は固定部３に固定される。固定部３は、矢印Ｂに示す様に引っ張り棒２の長さを調整し、矢印Ｂの向きに直交する軸を中心軸とした円弧状の矢印Ｃに示す様に引っ張り棒２の向きを調整し、斜め方向を向く矢印Ｄに示す様に引っ張り棒２の高さを調整する。夫々調整した位置で固定することができる。固定方法は、例えば、レバーロック機構により引っ張り棒２を固定する。更にレバーロック機構に加えて、引っ張り棒２を他の固定手段を追加することも可能である。例えば、針金等を巻いて固定するバネ固定機構にすることも出来る。施術中に処置器具を確実に固定することは、医療行為として重要事項である。 FIG. 1B is an enlarged view of a part of FIG. 1A. The base end side of the hook, which is the treatment instrument 1, is connected to the pull rod 2 by a detachable means, and the pull rod 2 is fixed to the fixing portion 3. The fixing portion 3 adjusts the length of the pull rod 2 as shown by the arrow B, and adjusts the direction of the pull rod 2 as shown by the arcuate arrow C centered on the axis orthogonal to the direction of the arrow B. Then, the height of the pull rod 2 is adjusted as shown by the arrow D pointing in the diagonal direction. It can be fixed at each adjusted position. As a fixing method, for example, the pull rod 2 is fixed by a lever lock mechanism. Further, in addition to the lever lock mechanism, it is also possible to add another fixing means for the pull rod 2. For example, a spring fixing mechanism for winding and fixing a wire or the like can be used. Reliably fixing the treatment instrument during the procedure is an important medical practice.

更に固定部３は、支え棒４によって支持部５へ支え台６を介して接続される。支え台６は、矢印Ｅに示す様に支持部５に沿って左右へスライドすることができる。又は、図に示す蝶ねじにより支持部５の自由な位置に設置することができる。 Further, the fixing portion 3 is connected to the support portion 5 by the support rod 4 via the support base 6. The support base 6 can slide left and right along the support portion 5 as shown by the arrow E. Alternatively, it can be installed at a free position of the support portion 5 by the thumbscrew shown in the figure.

以上のように矢印Ｂ、Ｃ、Ｄ、Ｅに沿ってその位置を自由に可変調整できることによって、処置器具１を患者の口腔開口状態を自由に変更し、その状態を固定することによって開口維持することが可能となる。支え台６は、支持部５の外側に取り付けられており、支え台６の上部は凡そ４５度傾いた平板となっている。この平板に支え棒４の下端が固定されることで、支え棒４の上端側が支持部５に対して外側斜め上方を向き、固定部３の矢印Ｂの調整量が広がり、処置器具１の自由度が大きくなる。処置器具１と、引っ張り棒２とは、容易に装着及び取り外しが可能で、そのような着脱手段としては、処置器具の端末形状によって異なるが、例えば、スプリング機能とオスメス勘合を用いた構造等が適用可能である（図示せず）。 As described above, the position can be freely variably adjusted along the arrows B, C, D, and E, so that the treatment instrument 1 can freely change the oral opening state of the patient and maintain the opening by fixing the state. It becomes possible. The support base 6 is attached to the outside of the support portion 5, and the upper portion of the support base 6 is a flat plate inclined by about 45 degrees. By fixing the lower end of the support rod 4 to this flat plate, the upper end side of the support rod 4 faces diagonally upward to the outside with respect to the support portion 5, the adjustment amount of the arrow B of the fixing portion 3 is widened, and the treatment instrument 1 is free. The degree increases. The treatment instrument 1 and the pull rod 2 can be easily attached and detached, and such attachment / detachment means may differ depending on the terminal shape of the treatment instrument, but for example, a structure using a spring function and male-female fitting may be used. Applicable (not shown).

本願発明の口腔開口維持装置をスタンド方式にした図２を説明する。処置器具１を備える支持部５は、基底部７から垂直に連結している支柱部８に接続される構成となっている。即ち、床面に固定される基底部７は、ストッパー部（ゴム床固定パット）、車輪部（キャスタ車輪）を有し、使用時は、床固定ペダルでストッパー部を床面に固定される。また、移動する際は、ストッパー部の固定を解除して車輪部で移動することが出来る。基底部７は、装置全体の重量バランスを保つ為に、必要に応じて重しを用いることも可能である。支柱部８は、支持部５の高さ調整を上下方向を向く矢印Ｆの方向にスライドすることによって可能となる。 FIG. 2 will be described in which the oral opening maintenance device of the present invention is a stand type. The support portion 5 provided with the treatment instrument 1 is configured to be connected to a support portion 8 which is vertically connected from the base portion 7. That is, the base portion 7 fixed to the floor surface has a stopper portion (rubber floor fixing pad) and a wheel portion (caster wheel), and when in use, the stopper portion is fixed to the floor surface with a floor fixing pedal. Further, when moving, the stopper portion can be released from being fixed and the wheel portion can be used for movement. The base portion 7 can also use a weight if necessary in order to maintain the weight balance of the entire device. The support portion 8 can be adjusted in height by sliding the support portion 5 in the direction of the arrow F pointing in the vertical direction.

矢印Ｆに沿った高さ調整及び矢印Ａに沿った幅調整は、施術前に事前に患者毎にセッティングされ、施術中に調整することはない。従って所謂、殺菌処理等の対応は不要である。
この様に、スタンド方式による本願発明により、施術者は患者の椅子、ベッド等に対応でき、基底部７の車輪部により、何処にでも移動でき、何処にでも処置が可能となる。 The height adjustment along the arrow F and the width adjustment along the arrow A are set for each patient in advance before the treatment and are not adjusted during the treatment. Therefore, it is not necessary to take measures such as so-called sterilization treatment.
As described above, according to the present invention based on the stand method, the practitioner can correspond to the chair, bed, etc. of the patient, and the wheel portion of the base portion 7 allows the practitioner to move anywhere and perform treatment anywhere.

本願発明の口腔開口維持装置を患者に適応しているのが図３に示す。図の様に、処置器具１（ここでは、ホックと筋鈎）で患者の口角を引っ張った状態で固定できるので、患者の口腔開口状態を維持できる。処置器具としてへらは、患者の舌を押さえる際に有効である。処置器具の数、種類は、特に限定はされず、施術の内容に応じて設定すれば良い。また、図示していないが、支持部５には、吸引管等を掛ける台を設けることも可能で、その位置も支え台６と同様に、左右にスライドして、又は蝶ねじにより自由に設定できる。支持部５を患者に応じて、図１（ａ）の矢印Ａの様に幅が調整できるのは前述の通りである。患者は、口腔が固定されているので、頭頸部も同時に固定されることとなる。 FIG. 3 shows that the oral opening maintenance device of the present invention is applied to a patient. As shown in the figure, since the patient's mouth corner can be fixed in a pulled state with the treatment instrument 1 (here, the hook and the muscle hook), the patient's oral opening state can be maintained. A spatula as a treatment device is effective in holding down the patient's tongue. The number and types of treatment instruments are not particularly limited, and may be set according to the content of the treatment. Further, although not shown, the support portion 5 can be provided with a base on which a suction pipe or the like is hung, and the position thereof can be freely set by sliding left and right or by using a thumbscrew as in the support base 6. it can. As described above, the width of the support portion 5 can be adjusted according to the patient as shown by the arrow A in FIG. 1 (a). Since the oral cavity is fixed in the patient, the head and neck will be fixed at the same time.

一定の開口状態での施術が終了すれば、例えば別の箇所の処置の為、別の術野確保に応じた口腔開口状態を、新たに処置器具１を引っ張り棒２と共に固定部３によって位置調整することで、別の開口形状を容易に確保できる。この様に施術の内容に応じて、処置器具１の種類、数量、位置、方向を自由に変更することによって、患者の口腔形状を大きく自由に変更し、術野を確保できる。
処置器具１、引っ張り棒２、固定部３、支え棒４、支え台６のこれらは、施術中に動かすので、殺菌処理が必要となる。これらの材料は殺菌処理にも問題なく対応できる材料を使用する。 When the treatment in a certain opening state is completed, for example, for the treatment of another place, the position of the oral opening state corresponding to the securing of another surgical field is newly adjusted by the fixing part 3 together with the pulling rod 2. By doing so, another opening shape can be easily secured. In this way, by freely changing the type, quantity, position, and direction of the treatment instrument 1 according to the content of the treatment, the oral shape of the patient can be largely freely changed and the surgical field can be secured.
Since these of the treatment instrument 1, the pull rod 2, the fixing portion 3, the support rod 4, and the support base 6 are moved during the treatment, sterilization treatment is required. For these materials, use materials that can be sterilized without any problem.

以上のような本願発明の口腔開口維持装置によれば、施術者は患者を図４のような位置関係において、施術者一人で患者の口腔開口状態を維持しながら処置が可能となり、更に施術者の意思通り術野を変更できるので、手術時間の短縮も期待できる。従来の図５の様に複数の助手による方法と比べて、格段に省力化が可能となり、前述の課題が解決できる。 According to the oral opening maintenance device of the present invention as described above, the practitioner can treat the patient in the positional relationship as shown in FIG. 4 while maintaining the oral opening state of the patient by the practitioner. Since the surgical field can be changed according to the wishes of the patient, the operation time can be expected to be shortened. Compared with the conventional method using a plurality of assistants as shown in FIG. 5, labor saving can be significantly achieved, and the above-mentioned problems can be solved.
