Description
本考案は、手術用器具の鈎に係り、特に、吸引機能を有する吸引鈎に関するものである。 The present invention relates to a scissors for a surgical instrument, and more particularly to a suction scissors having a suction function.
一般に、外科手術は生体組織や臓器等を切開、剥離しながら進められ、目標とする部位に対する術野を確保することが重要な作業と位置づけられる。こうした術野の確保には、鈎と呼ばれる手術器具が多く用いられる。鈎は、組織や臓器等を牽引し、保持する手術器具である。 In general, a surgical operation is performed while incising and peeling a living tissue, an organ, and the like, and securing an operative field for a target site is regarded as an important operation. In order to secure such a surgical field, a surgical instrument called a sputum is often used. A sputum is a surgical instrument that pulls and holds tissues and organs.
鈎を使用する際には、体腔内に溜まった血液や体液、生理食塩水等の洗浄液を吸引するための吸引具が同時に用いられるが、術野の確保及び作業スペース確保の観点から、同時に使用する手術器具は出来るだけ少ない方が望ましい。そこで、鈎と吸引具の両方の機能を有する手術器具、いわゆる吸引鈎が提案されている（特許文献１）。 When using a sputum, a suction tool for aspirating cleaning fluid such as blood, body fluid, and physiological saline collected in the body cavity is used at the same time, but it is used at the same time from the viewpoint of securing the surgical field and working space. It is desirable to use as few surgical instruments as possible. Therefore, a surgical instrument having both functions of a scissors and a suction tool, a so-called suction scissor has been proposed (Patent Document 1).
特許文献１に開示された吸引鈎は、鈎及び除去子の全体を中空構造にして先端に設けられた孔から吸引できるようにした鈎である。しかし、鈎は器具の性質上、必ず組織や臓器等に密着した状態で使用するために、吸引孔に組織等が付着して吸引の効率が落ち、場合によっては吸引孔が詰まって吸引ができなくなるという不具合があった。 The suction rod disclosed in Patent Document 1 is a rod that has a hollow structure for the entire flange and remover and can be sucked from a hole provided at the tip. However, due to the nature of the device, the sputum must be used in close contact with tissues and organs. There was a problem of disappearing.
上記不具合は吸引鈎に限定されるものではなく、吸引具としての不具合でもある。例えば特許文献２には、吸引プローブの開口部先端に複数の吸引孔を有するキャップを設けることにより、吸引プローブの開口部が直接閉塞されるという事態を防止する吸引プローブが開示されている。
しかしながら、特許文献２に開示された吸引プローブにあっては、吸引孔はキャップの外周縁上に設けられているため、組織等がキャップの外周面を覆ってしまうと、結果的に吸引孔が閉塞することとなり、上記不具合を解消するには至っていない。
The above problem is not limited to the suction rod, but is also a problem as a suction tool. For example, Patent Document 2 discloses a suction probe that prevents a situation in which the opening of the suction probe is directly blocked by providing a cap having a plurality of suction holes at the tip of the opening of the suction probe.
However, in the suction probe disclosed in Patent Document 2, since the suction hole is provided on the outer peripheral edge of the cap, when the tissue or the like covers the outer peripheral surface of the cap, the suction hole is consequently formed. It will be blocked and the above problems have not been solved.
また、特許文献３には、吸引効率を改善するために先端部近傍の側面に複数の吸引孔を設けた吸引チューブが開示されている。しかしながら、吸引孔は先端部の外周縁上に設けられているため、組織等が先端部を覆ってしまった場合には、上記不具合を解消するに至っていない。
本考案は、以上のような従来からの不具合を解決するためのものであって、その課題は、生体組織や臓器等が吸引孔部に密着した際にも、確実に血液や洗浄液を吸引しながら鈎として使用することができる吸引鈎を提供することにある。 The present invention is intended to solve the above-mentioned conventional problems, and the problem is that blood and cleaning fluid can be reliably sucked even when a living tissue or organ is in close contact with the suction hole.

A certain gap is ensured between 17 and the organ, tissue or the like. Therefore, even when a living tissue, an organ, or the like adheres in any direction of the suction hole 18, the blood or the cleaning liquid can be reliably sucked.
In particular, in the suction rod 10, a certain gap is secured between the projecting portion 19 and both side surface portions 27 in the width direction of the suction hole body 25. Accordingly, even when the axial tip portion 22 and the radial tip portion 24 of the suction hole main body 25 provided with the suction holes 17 are covered with organs, tissues, etc., the liquid is discharged from the both side surfaces 27 in the width direction. The suctioned liquid is guided to the suction hole 17 formed in the radial tip end 24 of the suction hole body 25 by the gap and can be efficiently sucked.
本実施の形態に係る吸引鈎１０は、上記本体管部１１及び上記吸引孔部１８が湾曲形成されている場合を例に説明したが、上記構成に限定されない。
また、本実施の形態に係る吸引孔部１８は、上記軸方向先端部２２及び径方向先端部２４に上記吸引孔１７が開設された細長直方体状の吸引孔部本体２５と、平面略長方形状であって、上記吸引孔部本体２５の幅方向両端部２６に設けられた上記係止面部２１を有する臓器係止部２０を備え、上記張り出し部１９は上記吸引孔部本体２５の長さ方向の略全域に設けられていると共に、上記吸引孔部本体２５の幅方向両側面部２７は、上記張り出し部１９よりも幅方向内方に設けられている場合を例に説明したが、上記構成に限定されず、上記吸引孔１７が設けられた部位において上記本体管部１１の外方へ延出する張り出し部１９を有する臓器係止部２０を有するように構成されていればよい。
