(A),(B)に示すように各鋏構成部材83,84のストッパー100,101間が当接する位置(最終閉操作位置)まで移動する。 (A), it is moved to a position between the stopper 100 and 101 abut each scissor constituting members 83 and 84 as shown in (B) (final closing operation position). このとき、ヒーター92,93 At this time, the heater 92 and 93
の接触面92a,93aの後端部間も当接し、ヒーター92,93の接触面92a,93a全体が閉じるように設定されている。 The contact surface 92a, between the rear end portion of 93a is also in contact with the contact surface 92a of the heater 92 and 93, it is set so that the entire 93a is closed. 【0053】次に、上記構成の作用について説明する。 Next, a description will be given of the operation of the above configuration.
本実施の形態では各鋏構成部材83,84の操作部91 In this embodiment the operation unit 91 of the scissor constituting members 83 and 84
による処置具本体82の各ジョー86,87の閉操作時には、まず図6(A),(B)に示す第1の閉操作位置に移動し、その後、図7(A),(B)に示す最終閉操作位置まで移動する。 During closing operation of the jaw 86, 87 of the instrument body 82 by, firstly FIG. 6 (A), the move to the first closing operation position shown in (B), then, FIG. 7 (A), the (B) to move to the final closing operation position shown. そして、第1の閉操作位置では各ジョー86,87のヒーター92,93の接触面92 Then, the first closing operation position the contact surface 92 of the heater 92 and 93 of each jaw 86 and 87
a,93aの先端部同士が当接した際に、ヒーター9 a, when the leading ends of 93a abuts, a heater 9
2,93の接触面92a,93aの後端部間には隙間1 2,93 of the contact surface 92a, a gap between the rear end portion of 93a 1
02が形成される。 02 is formed. このとき、各鋏構成部材83,84 At this time, the pincers members 83 and 84
のストッパー100,101間は当接しない状態で保持される。 During the stopper 100, 101 is held in a state without contact. 【0054】さらに、図6(A),(B)に示す各ジョー86,87の閉操作時の第1の閉操作位置から操作部91に更に強く閉鎖力を加えることにより、図7 [0054] Further, FIG. 6 (A), the by adding more strongly closing force to the operating part 91 from the first closing operation position at the time of closing operation of the jaw 86 and 87 (B), the 7
(A),(B)に示すように各鋏構成部材83,84のストッパー100,101間が当接する位置(最終閉操作位置)まで移動する。 (A), it is moved to a position between the stopper 100 and 101 abut each scissor constituting members 83 and 84 as shown in (B) (final closing operation position). このとき、各ジョー86,87 In this case, each jaw 86 and 87
の根元側部分103が弾性変形して、ヒーター92,9 Base side portion 103 are elastically deformed, the heater 92,9
3の接触面92a,93aの後端部間も当接し、ヒーター92,93の接触面92a,93a全体が接触する状態で閉じる。 3 of the contact surface 92a, between the rear end portion of 93a is also in contact with the contact surface 92a of the heater 92 and 93, it closed in a state in which the entire 93a is in contact. 【0055】なお、ヒーター92,93の接触面92 [0055] In addition, the contact surface 92 of the heater 92 and 93
a,93aの後端部間が当接した時、ジョー86,87 When a, between the rear end portion of 93a is in contact with the jaws 86 and 87
の先端部間には1kgf(9.8N)以上の荷重が加わっていることが望ましい。 It is preferable that the load is applied at least 1 kgf (9.8 N) is between the tip. 【0056】また、上下のストッパー100,101はヒーター92,93の接触面92a,93aの後端部間が当接した時に接触する状態に調整されている。 [0056] Also, the upper and lower stoppers 100, 101 is adjusted in a state of contact when the contact surface 92a of the heater 92 and 93, between the rear end portion of 93a is in contact. なお、 It should be noted that,
図示しない調節ネジなどで上下のストッパー100,1 Top and bottom of the stopper and the like (not shown) the adjustment screw 100,
01の当接位置を調節可能になっている。 It has become adjustable abutment position 01. 【0057】ここで、ストッパー100,101が無い場合には、図6(A),(B)の最終閉操作位置から更に閉鎖力を加えると、各ジョー86,87の根元側部分103がさらに弾性変形して各ジョー86,87のヒーター92,93の接触面92a,93aの先端部に隙間があく。 [0057] Here, when the stopper 100, 101 is not, FIG. 6 (A), the further the addition of closing force from the final closing operation position of (B), the base portion 103 of each jaw 86 and 87 is further the contact surface 92a of the elastically deformed heaters 92 and 93 of each jaw 86 and 87, a gap is drilled in the tip of the 93a. なお、ジョー86,87の弾性変形の範囲はヒーター92,93の取り付け方法により、たとえばジョー86,87に比較的ルーズに取り付けた場合等、図6 Incidentally, the method of attaching a range of elastic deformation of the jaws 86 and 87 the heater 92, for example, when such attached relatively loosely jaws 86 and 87, FIG. 6
(A)中に示すAの範囲を超える場合もある。 May exceed the range of A shown in (A). 【0058】そこで、上記構成のものにあっては次の効果を奏する。 [0058] Thus, the apparatus having the configuration described above produces the following effects. すなわち、本実施の形態では各鋏構成部材83,84の基端部側における手指挿入リング89,9 That is, in this embodiment the finger inserting ring at the proximal end side of the scissor constituting members 83, 84 89,9
0の近傍位置に操作部91の内側に向けて操作部91の閉鎖位置を規制するストッパー100,101をそれぞれ突設したので、操作部91に過度の閉鎖力を加えても、ストッパー100,101が当接して、各ジョー8 Since 0 in the vicinity of the stopper 100, 101 for regulating the closing position of the operating portion 91 toward the inside of the operating portion 91 projecting from each even apply excessive closing force to the operating unit 91, a stopper 100, 101 but in contact with, each jaw 8
6,87のヒーター92,93の接触面92a,93a The contact surface 92a of the heater 92 and 93 of 6,87, 93a
の先端部間に隙間ができることを防止することができる。 It is possible to prevent the gap is formed between the tip portion. 【0059】さらに、ストッパー100,101が当接して作動している状態ではヒーター92,93の接触面92a,93aの全面の広い範囲が閉じているとともに、ジョー86,87には1kgf以上の充分な閉鎖力が働いている。 [0059] Further, the contact surface 92a of the heater 92, 93 in a state where the stopper 100, 101 is operating in contact, with a wide range of 93a over the entire surface is closed, sufficiently above 1kgf the jaws 86 and 87 closing force is working Do not. そのため、ジョー86,87間で把持されている生体組織が充分圧縮され、凝固が良好となる効果がある。 Therefore, the living tissue being grasped between the jaws 86 and 87 are sufficiently compressed, solidification has the effect to be improved. 【0060】また、使用者もストッパー100,101 [0060] Also, the user stopper 100, 101
が作動するまで操作部91を握ればよいので、閉鎖力の調整を気にする必要が無い。 Since There should grasp the operation unit 91 to operate, there is no need to worry about the adjustment of the closing force. そのため、凝固処置具81 Therefore, the coagulation treatment instrument 81
の操作が一層、容易となる効果もある。 There further operation is also facilitated effect. 【0061】また、図7(C)は第5の実施の形態(図6(A),(B)および図7(A),(B)参照)の凝固処置具81の変形例を示すものである。 [0061] Further, FIG. 7 (C) is a fifth embodiment (FIG. 6 (A), (B) and FIG. 7 (A), (B) refer) shows a modification of the coagulation treatment instrument 81 it is. 本変形例はジョー86,87の途中にヒーター92,93を配置され、ジョー86,87の先端部分によって接触面92 This modification is arranged a heater 92, 93 in the middle of the jaws 86 and 87, the contact surface 92 by the tip portion of the jaws 86 and 87
a,93aの一部が形成されている。 a, a portion of 93a is formed. この場合も第5の実施の形態と同様の効果が得られる。 In this case the same effect as the fifth embodiment can be obtained. 【0062】また、図8(A)〜(F)は本発明の第6 [0062] Further, the sixth FIG 8 (A) ~ (F) the invention
