Description

本発明は、アンビルとハンドピースの端部を覆うようにカバーを設けた超音波溶着器に関するものである。   The present invention relates to an ultrasonic welder provided with a cover so as to cover ends of an anvil and a handpiece.

従来、図３及び図４に示すように、ハンドピース１の一端に超音波振動子２のホーン２ａの端部が突出され、ハンドピース１の側部にアンビル部３の摺動部材３ａが摺動可能に装着され、摺動部材３ａからアンビル３ｂがほぼ垂直に形成され、アンビル３ｂの端部は超音波振動子２のホーン２ａの端部と接触するように構成され、ハンドピース１の両側面に装着された回動軸４で回動部材５の三角部材５ａの頂点部分が支持され、又、回動部材５は三角部材５ａからハンドピース１の下方に斜めにレバー５ｂが形成され、さらに、回動部材５の三角部材５ａの底部近傍に駆動軸６が固着され、又、アンビル部３の摺動部材３ａを貫通して支持軸７が摺動部材３ａに固着され、駆動軸６と支持軸７の間にＵ字状のバネ８が装着され、又、ハンドピース１の側部に発振スイッチ９が装着され、レバー３ｂに装着した突出部５ｃで発振スイッチ９を押すようにした超音波溶着器が提案されている。   Conventionally, as shown in FIGS. 3 and 4, the end of the horn 2 a of the ultrasonic transducer 2 protrudes from one end of the hand piece 1, and the sliding member 3 a of the anvil portion 3 slides on the side of the hand piece 1. The anvil 3b is mounted so as to be movable, and the anvil 3b is formed substantially vertically from the sliding member 3a. The end of the anvil 3b is configured to come into contact with the end of the horn 2a of the ultrasonic vibrator 2, and The rotating shaft 4 mounted on the surface supports the apex portion of the triangular member 5a of the rotating member 5, and the rotating member 5 is formed with a lever 5b obliquely below the handpiece 1 from the triangular member 5a. Further, the drive shaft 6 is fixed to the vicinity of the bottom of the triangular member 5 a of the rotating member 5, and the support shaft 7 is fixed to the slide member 3 a through the sliding member 3 a of the anvil portion 3. A U-shaped spring 8 is mounted between the support shaft 7 and the hand. Over side to the oscillation switch 9 of the scan 1 is mounted, ultrasonic welding instrument which has to press the oscillation switch 9 protruding portion 5c attached to the lever 3b are proposed.

しかしながら、この超音波溶着器では、被溶着物１０の内部に血液や人体に有害な物質が封入されている場合には、アンビル３ｂと超音波振動子２のホーン２ａとの間に被溶着物１０を挟持して溶着する時、被溶着物１０が破損すると、被溶着物１０の内部の血液や有害な液体が飛び散り、人体に害を及ぼす恐れがあるという問題がある。
特願２００４−２５２２２６ However, in this ultrasonic welder, when a substance harmful to blood or the human body is sealed inside the object to be welded 10, the object to be welded is interposed between the anvil 3 b and the horn 2 a of the ultrasonic vibrator 2. When the object 10 is sandwiched and welded, if the object 10 is damaged, there is a problem that blood or harmful liquid inside the object 10 may be scattered, which may cause harm to the human body.
Japanese Patent Application No. 2004-252226

解決しようとする問題点は、従来の超音波溶着器では、被溶着物の内部に血液や人体に有害な物質が封入されている場合には、溶着時に被溶着物１０が破損すると、被溶着物１０の内部の血液や有害な液体が飛び散り、人体に害を及ぼす恐れがあるという問題がある。   The problem to be solved is that, in the conventional ultrasonic welder, if a substance harmful to blood or the human body is sealed inside the object to be welded, if the object to be welded 10 is damaged at the time of welding, the object to be welded is welded. There is a problem that blood and harmful liquid inside the object 10 may scatter and cause harm to the human body.

本発明では、ハンドピースは超音波振動子を内蔵し、該超音波振動子のホーンの先端が端部に突出され、アンビル部はハンドピースの側部に摺動部材を装着し、摺動部材から突出するアンビルの接触部が前記超音波振動子のホーンと対向するように装着され、カバーはアンビル部のアンビルの先端部を覆い、被溶着物をセットする切り込みガイドをアンビルの先端部から超音波振動子のホーンの端部の間に設け、被溶着物を溶着する時に、アンビルと超音波のホーンで被溶着物を溶着するとともに、カバーで被溶着物と前記ハンドピースの端部を覆うように設けるものである。   In the present invention, the handpiece has a built-in ultrasonic transducer, the tip of the horn of the ultrasonic transducer is protruded at the end, the anvil portion has a sliding member mounted on the side of the handpiece, and the sliding member The anvil contact part protruding from the ultrasonic transducer horn is mounted so as to face the horn of the ultrasonic vibrator, the cover covers the anvil tip of the anvil part, and a cutting guide for setting the object to be welded is placed from the tip of the anvil. Provided between the horn ends of the sonic vibrator, and when welding the welded object, the welded object is welded with an anvil and an ultrasonic horn, and the welded object and the end of the handpiece are covered with a cover. It is provided as follows.

本発明の超音波溶着器は、アンビルと被溶着物を覆うカバーを設け、又、カバーにアンビルの端部と超音波振動子のホーンとの間に被溶着物をセットする時にガイドとなる切り込みを設けることにより、被溶着物をセットする時に切り込みに被溶着物を押し当てることにより、被溶着物を所定の位置に簡単にセットすることができるとともに、溶着時に、被溶着物の溶着部分が破損して、被溶着物の内部に封入された有害な物質が飛び散らないように、カバーで被溶着物の溶着部分を覆うことができるという利点がある。   The ultrasonic welder of the present invention is provided with a cover that covers the anvil and the object to be welded, and a notch serving as a guide when the object to be welded is set between the end of the anvil and the horn of the ultrasonic vibrator on the cover. By setting the welding object, it is possible to easily set the welding object at a predetermined position by pressing the welding object to the notch when setting the welding object, and at the time of welding, the welding part of the welding object is There is an advantage that the welded portion of the object to be welded can be covered with the cover so that the harmful substance sealed inside the object to be welded is not scattered.

図１は本発明の実施例の超音波溶着器の側面図、図２は回動部材を動作した状態の側面図で、１はハンドピース、２は超音波振動子、３ｂはアンビル、４は回動軸、５は回動部材、６は駆動軸、７は支持軸、８はバネ、９はスイッチ、１０は被溶着物で、これらの構成は上記従来例と同じであるので、説明は省略するが、本実施例では、アンビル３の端部とハンドピース１の端部を覆うようにカバー１１を摺動部材３ａに装着し、カバー１１を押し付けることにより被溶着物１０をセットする切り込みガイド１１ａを形成する。   FIG. 1 is a side view of an ultrasonic welder according to an embodiment of the present invention, FIG. 2 is a side view of a state in which a rotating member is operated, 1 is a handpiece, 2 is an ultrasonic transducer, 3b is an anvil, Rotating shaft, 5 is a rotating member, 6 is a driving shaft, 7 is a supporting shaft, 8 is a spring, 9 is a switch, and 10 is a welded object. Although omitted, in this embodiment, the cover 11 is attached to the sliding member 3 a so as to cover the end of the anvil 3 and the end of the handpiece 1, and the weld 10 is set by pressing the cover 11. A guide 11a is formed.

このように構成された本実施例の超音波溶着器では、図１及び図２に示すように、被溶着物１０をカバー１１の切り込みガイド１１ａによってセットし、ハンドピース１の側面に回動可能に装着された回動部材５のレバー５ｂをハンドピース１の方向に押し付けると、回動部材５の三角部材５ａに固着された駆動軸６でＵ字状のバネ８がバネの力に抗して押され、バネ８が戻る力によって、アンビル部３の摺動部材３ａに固着された支持軸７が押されるので、支持軸７はバネ８の戻る力によって移動され、アンビル部３の摺動部材３ａと一体となったアンビル３ｂの端部が超音波振動子２のホーン２ａの方向に移動し、被溶着物１０がアンビル３ｂと超音波振動子２のホーン２ａで押圧されると、カバー１１は被溶着物１０の外側を覆い、さらに、ハンドピース１の端部を覆うので、被溶着物１０が破損しても、被溶着物１０の内部に封入されている物質が飛び散ることがないという利点がある。   In the ultrasonic welder of the present embodiment configured as described above, as shown in FIGS. 1 and 2, the object to be welded 10 is set by the cut guide 11 a of the cover 11 and can be rotated to the side surface of the handpiece 1. When the lever 5b of the rotating member 5 mounted on the head is pressed in the direction of the handpiece 1, the U-shaped spring 8 resists the spring force by the drive shaft 6 fixed to the triangular member 5a of the rotating member 5. The support shaft 7 fixed to the sliding member 3a of the anvil portion 3 is pushed by the force that the spring 8 returns and the support shaft 7 is moved by the return force of the spring 8 to slide the anvil portion 3. When the end of the anvil 3b integrated with the member 3a moves in the direction of the horn 2a of the ultrasonic vibrator 2, and the object to be welded 10 is pressed by the anvil 3b and the horn 2a of the ultrasonic vibrator 2, the cover 11 covers the outside of the object 10 to be welded. , Since covers the end portion of the handpiece 1, even if the weld deposit 10 is damaged, there is an advantage that scatters that no substances enclosed in the inside of the weld deposit 10.

なお、上記実施例では、カバー１１は被溶着物１０とハンドピース１の端部を覆うようにしたが、ハンドピース１のカバーと超音波振動子２の間に入るようにしてもよい。   In the above embodiment, the cover 11 covers the object to be welded 10 and the end of the handpiece 1, but it may be inserted between the cover of the handpiece 1 and the ultrasonic transducer 2.
