An important design 目标是,在不对来自装载程序的夹子进行任何压缩的情况下将手术夹子装在钳口之间。在装载过程中的夹子的这些弯曲或扭转经常会有许多意想不到的后果。在装载时的这种压缩可能会略微地改变夹子在钳口之间的对准。这会使外科医生将夹子从钳口之间移除以便丢弃夹子。另外,这种预载压缩可能会略微地压缩夹子的某些部分而改变其几何。这会使外科医生将夹子从钳口之间移除以便丢弃夹子。 The goal is carried out at any compression in the case where the surgical clip between the jaws in these bending or twisting of the clip during loading often has a number of unintended consequences from the clip does loader Upon loading such compression may alter slightly the alignment of the clip between the jaws. this will cause the surgeon to remove the clip from between the jaws for discarding the clip. Additionally such preloading compression may slight compress the clip some portion changes its geometry. this will cause the surgeon to remove the clip from between the jaws for discarding the clip.

[0008] 经常在远离切口的地方执行内窥镜或者腹腔镜程序。 [0008] The endoscopic or laparoscopic procedures are often performed remotely from the incision in. 因此,对于位于装置近端的用户而言,视野或者触觉反馈的减小可能使夹子的施加复杂化。 Thus, for a user device located at the proximal end of the field of view or reduced tactile feedback application of clips may be complicated. 因此希望通过向用户提供单个夹子被发射的指示、包含在装载单元中的夹子的损耗或者任何其它手术事件的指示来改善器械的操作。 It is therefore desirable to provide an indication by the clip to be transmitted to a single user, or loss of any indication of the clip other surgical event is contained in the loading unit to improve the operation of the instrument. 还希望提供这样一种手术施夹器:其促进了夹子的成功负载并且分开该手术施夹器的钳口,然后将夹子装在钳口之间以防止夹子的任何损坏或者过度压缩,并在发射前防止钳口压在夹子上。 It is also desirable to provide a surgical clip applier: clip which contributed to the success of the load and separated from the jaws of surgical clip applier, and then loads the clip between the jaws to prevent any damage or excessive compression of the clip, and before launch to prevent pressure on the clip jaws.

[0188] 继续参照图38和图39,当驱动组件120和驱动杆140处于缩回位置时,滑动接头180位于最近侧位置,并且因为驱动通道168的凸起168d布置在滑动接头180的窝眼182b中,所以驱动通道168也位于最近侧位置。 [0188] With continued reference to FIGS. 38 and 39, when drive assembly 120 and drive bar 140 are in the retracted position, slider joint 180 is located proximal-most position, and since the projections 168d of drive channel disposed in the pocket 168 of slider joint 180 in 182b, the drive channel 168 is also located proximal-most position. 如图38和图39所示,滑动接头180紧靠从下壳体152b突出的物理止挡152e (参见图30)。 Shown in FIGS. 38 and 39, slider joint 180 abuts against the projection 152b of the lower case physical stop 152e (see FIG. 30).

[0189] 如图40和图41所示,当驱动组件120和驱动杆140处于缩回位置时,楔形板锁190位于最近侧位置以使从其尾部190c延伸的齿190e布置在形成于下壳体152b中的倾斜凸耳152f的近侧(参见图30和图31)。 [0189] FIGS. 40 and 41, when drive assembly 120 and drive bar 140 are in the retracted position, wedge plate lock 190 is located proximal-most position such that tooth 190e extending from tail 190c formed in the lower case disposed ramped ledge 152f of the proximal body 152b (see FIG. 30 and FIG. 31). 如图41所示,楔形板锁190紧靠从下壳体152b突出的物理止挡152g。 As shown, wedge plate 190 abuts against lock 41 from lower housing 152b protrudes physical stop 152g. 同样如图41所示,楔形板释放装置194布置在第一位置处以便其齿194c突入到形成于驱动通道168的侧壁168b中的窗口168e中。 Shown, wedge plate release means also shown 41,194 at a first position disposed so that tooth 194c thereof projects into window 168e formed in side wall 168b of drive channel 168 in the middle.

[0190] 如图42和图43所示,当驱动组件120和驱动杆140处于缩回位置时,推杆156的推动器156c布置在保持在夹子载体164中的最远侧夹子“C”的后跨部的近侧。 [0190] As shown in FIG. 42 and 43, when drive assembly 120 and drive bar 140 are in the retracted position, pusher 156c of pusher bar 156 is disposed in the holding clip carrier 164 in a distal-most clip "C", after the inter-proximal portion. 最远侧夹子“C”通过其柄脚164b保持在夹子载体164的通道中。 Distal-most clip "C" by tangs 164b of clip carrier 164 held in the channels of. 并且,如上所述,在此位置处,楔形板172位于最近侧位置以便其远端172a位于钳口106的近侧。 Further, as described above, at this position, wedge plate 172 is located so that its distal-most position 172a is located proximal jaw 106.

[0191] 如图43所示,当驱动通道168位于最近侧位置时,其远端从钳口106的近侧凸轮表面106b脱离。 [0191] As shown in FIG 43, when drive channel 168 is located proximal-most position, its distal end from the proximal camming surface 106b of jaws 106 disengaged.

[0192] 现转到图44至图54,在初始行程的第一阶段中,随着扳机108从初始位置被挤压或致动,扳机108使得叉形连杆122向着远侧方向移动曲柄板124,而这将使得驱动连接器134和柱塞135向远侧移动并使得驱动杆140向远侧移动。 [0192] Turning now to FIGS. 44 to 54, in a first stage of the initial stroke, as the trigger 108 is squeezed or actuated from the initial position, trigger 108 causes wishbone link 122 to move crank plate in a distal direction 124, which will cause the drive connector 134 and plunger 135 is moved distally and drive bar 140 is moved distally. 当随着柱塞135向远侧移动,弹簧136被压缩初始量。 When the plunger 135 to move distally as the spring 136 is compressed an initial amount.

[0193] 与此同时,随着曲柄板124向远侧移动,齿条124a的齿与棘爪224的齿224a接合,棘爪224移出或旋转出曲柄板124的远侧凹槽124a。 [0193] Meanwhile, as crank plate 124 is moved distally the teeth of rack 124a and 224a pawl tooth 224 engages the pawl 224 to rotate out of or out of distal recess 124a of crank plate 124 is. 这样,在没有完成完整的远侧行程的情况下,曲柄板124不能回到最近侧位置。 Thus, in the case where there is no complete distal stroke complete, crank plate 124 can not return to a proximal-most position.

[0194] 如图44所示,随着扳机108被挤压初始量,臂127开始平移通过反馈构件126的滚道126a。 [0194] shown in Figure 44, as trigger 108 is squeezed an initial amount, arm 127 begins to translate through the feedback member 126 raceway 126a.

[0195] 如图46所示,随着驱动杆140向着远侧方向移动,驱动杆140向着远侧方向推动连接板174。 [0195] As shown in FIG. 46, as drive bar 140 is moved in a distal direction, drive bar 140 push connector plate 174 in a distal direction. 因为推杆156通过第二弹簧夹子157b选择性地连接于连接板174,推杆156被向着远侧方向推进或拉动。 Since pusher bar 156 is selectively connected to connector plate 174 via second snap clip 157b, pusher bar 156 is advanced or pulled in a distal direction. 并且,因为楔形板172通过第三弹簧夹子157c选择性地连接于连接板174,楔形板172也被向着远侧方向推进或拖动。 Also, since wedge plate 172 is selectively connected to the connecting plate 157c through the third spring clip 174, wedge plate 172 is also advanced or dragged in a distal direction.

[0196] 随着驱动杆140向着远侧方向移动,其细长狭槽140a也向着远侧方向移动以使滑动接头182的凸起182a在相对于其的近侧方向上平移。 [0196] As drive bar 140 is moved in a distal direction, elongate slot 140a thereof is also moved in a distal direction so that the projection 182a of slider joint 182 is translated in the proximal direction relative thereto.

[0197] 如图47至图49所示,随着楔形板172向着远侧方向移动,因为楔形板172的凸起172b保持在楔形板锁190的窝眼190d中,楔形板锁190被向着远侧方向移动或拖动,这使得其尾部190c的齿190e被用凸轮带动越过形成于下壳体152b中的倾斜凸耳152f,从而从倾斜凸耳152f的近侧位置移动到倾斜凸耳152f的远侧位置。 [0197] As shown in FIG. 47 to FIG. 49, as wedge plate 172 is moved in a distal direction, since the projection 172 of wedge plate 172b held in the pocket 190D wedge plate lock 190, a wedge plate lock 190 is toward the far side or drag direction, which teeth 190e 190c so that the tail is driven cam formed in lower housing 152b across the ramped ledge 152f, to move from a proximal ramped ledge 152f to a position inclined ledge 152f distal position. 随着楔形板锁190向着远侧方向移动,偏置构件192被压缩初始量。 As wedge plate lock 190 is moved in a distal direction, biasing member 192 is compressed an initial amount. 如图49所示,楔形板锁190向着远侧方向移动直至楔形板锁190紧靠形成于下壳体152b中的物理止挡。 As shown in FIG. 49, wedge plate lock 190 is moved in a distal direction until wedge plate lock 190 abuts against the lower housing 152b is formed in the physical stop.

[0198] 如图47A所示,随着推杆156向着远侧方向移动,推进板162的翼片162b在推杆156的侧凹槽156f中平移预定距离,直到翼片162b接触或接合推杆156的侧凹槽156f的近端。 [0198] FIG 47A, as pusher bar 156 is moved in a distal direction, fins advancer plate 162 translate 162b a predetermined distance in side recesses 156f of pusher bar 156 until fins 162b contact with or engage the plunger side recesses 156f of the proximal end 156.

[0199] 如图47B和图47C所示,随着楔形板172向着远侧方向移动,由于连接板174的第二杆174c与第三弹簧夹子157c的连接,通过保护装置防止了连接板174的第二杆174c过早地从第三夹钳157c脱离。 [0199] As shown in FIG. 47B and 47C, as wedge plate 172 is moved in a distal direction, since the second stem 174c of connector plate 174 with third snap clip 157c is connected through the protective means prevents the connection plate 174 second stem 174c 157c prematurely disengaged from the third clamp. 特别地,随着连接板174向着远侧方向移动,保护装置198作用于第三弹簧夹子157c的尖头的尖端以防止尖头由于第二杆174c所产生的远侧力作用于其上的力而向外张开。 In particular, as the connector plate 174 in a distal direction, the protective means 198 acting on the tip of third snap clip 157c to prevent the tines distally force since the tip 174c of the second lever to a force generated thereon The flare outward.

[0200] 如图50所示,随着推杆156向着远侧方向移动,其推动器156c接合最远侧夹子“C”的后跨部并开始向着远侧方式推动最远侧夹子“C”。 [0200] As shown in FIG. 50, as pusher bar 156 is moved in a distal direction pusher 156c thereof engages the distal-most clip "C" cross-section and starts pushing a distal manner distal most clip "C" . 随着推杆156向着远侧方向移动最远侧夹子“C”,最远侧夹子“C”从夹子载体164的柄脚164b的后方脱离并开始进入到钳口106的通道106a中。 With the plunger 156 in a distal direction moves distal-most clip "C", distal-most clip "C" disengaged from the rear tangs 164 of clip carrier 164b and the jaws 106a entered into the passage 106.

[0201] 如图51所示,随着楔形板172向着远侧方向移动,其远端172a进入钳口106之间,使得钳口106向外张开。 [0201] As shown in FIG 51, as wedge plate 172 is moved in a distal direction, distal end 172a thereof enters between jaws 106 causing jaws 106 to open outwardly.

[0202] 如图52至图54所示,一旦楔形板锁190紧靠形成于下壳体152b中的物理止挡,则防止了楔形板172向着远侧方向进一步移动。 [0202] As shown in FIG. 54 to FIG. 52, once wedge plate lock 190 abuts against the lower housing 152b is formed in the physical stop, wedge plate 172 is prevented from further movement in the distal direction. 然而,驱动杆140继续向着远侧方向移动连接板174。 However, drive bar 140 continues to move connector plate 174 in a distal direction. 因为连接板174被继续向远侧推动,所以一旦第三弹簧夹子157c的尖头的尖端向远侧移动到超过保护装置198,则作用于第二杆174c上的力足够使得第三弹簧夹子157c的尖头向外张开并使得第二杆174c从其间脱开,从而使得连接板174继续向着远侧方向移动。 Since connector plate 174 to continue to be pushed distally, once the third snap clip 157c of the pointed tip beyond guard 198, the action is moved distally on the second stem 174c of sufficient force such that the third snap clip 157c and such that the outwardly flared prongs 174c is disengaged from the second rod therebetween, so that the connector plate 174 to continue to move in a distal direction.

[0203] 现转到图55至图69,随着扳机108从初始行程的第一阶段被进一步挤压或致动通过初始行程的第二阶段,扳机108使得叉形连杆122进一步向着远侧方向移动曲柄板124,而这使得驱动连接器134并随后使得柱塞135进一步向远侧移动且进一步向着远侧移动驱动杆140。 [0203] Turning now to FIGS. 55 to 69, as trigger 108 is further squeezed from the first stage of the initial stroke through a second stage or actuation of the initial stroke, trigger 108 causes wishbone link 122 to further distally direction crank plate 124, causes drive connector 134 and subsequently plunger 135 so that further distal movement and further drive bar 140 is moved distally. 随着柱塞135向远侧移动,弹簧136被压缩进一步的量。 As the plunger 135 is moved distally, spring 136 is compressed a further amount.

[0204] 与此同时,随着曲柄板124向着远侧移动,其齿条124a的齿相对于棘爪224的齿224a进一步向着近侧移动。 [0204] Meanwhile, as crank plate 124 is moved distally, the teeth of the rack 124a thereof move further proximally toward the tooth 224a of pawl 224. 这样,在没有完成完整的远侧行程的情况下,曲柄板124仍不能返回到最近侧位置。 Thus, in the absence of completion of a full distal stroke, crank plate 124 still can not return to a proximal-most position.

[0205] 如图55所示,随着曲柄板124向着远侧移动预定距离之后,其臂124d接合或接触致动板128的指部128b。 [0205] As shown in FIG 55, then as crank plate 124 is moved distally a predetermined distance, arm 124d thereof engages or contacts finger actuator plate 128 of the portion 128b. 随着曲柄板124进一步向着远侧推进,曲柄板124向着远侧方向推动或拉动致动板128,从而致动计数致动杠杆130以激活计数机构132。 As crank plate 124 is further advanced distally, crank plate 124 in a distal direction pushes or pulls actuator plate 128, thereby actuating counter actuation lever 130 to activate counter mechanism 132.

[0206] 特别地,当致动板128向着远侧移动足够距离时,在其槽128b中用凸轮带动计数致动杠杆130的第二臂130b并促使其旋转,导致计数致动杠杆130的第一臂130a接合计数机构132,从而实现其显示器中的变化。 [0206] In particular, when actuator plate 128 is moved distally a sufficient distance, in its cammed within slot 128b of counter actuation lever 130 of the second arm 130b and causes its rotation, causing the first counter actuation lever 130 engaging arm 130a counter mechanism 132, in order to achieve a change in the display thereof. 特别地,显示手术施夹器100中剩余的夹子的数目的显示器将减少一个。 Specifically, the display device 100 the number of clips remaining in surgical clip applier will display a decrease. 可选择地,夹子计数机构将增加一个或产生某些其他变化。 Alternatively, the clip counter mechanism will increase or produce a certain other changes.

[0207] 随着扳机108被进一步挤压时,臂127继续平移通过反馈构件126的滚道126a。 [0207] As the trigger 108 is squeezed further, arm 127 continues to translate through race 126 of feedback member 126a. 在这一点上,在扳机108的挤压中,手术夹子被装入钳口106中。 At this point in the squeezing of trigger 108, a surgical clip is loaded into the jaws 106. 相应地,臂127将与形成于反馈构件126的滚道126a中的梯级126b相互作用并产生告知用户夹子已被装入钳口中的听觉/触觉指示。 Accordingly, the arm 127 formed in race 126a of feedback member 126 in steps 126b inform a user interact with each clip has been loaded into the jaws of the audible / tactile indication.

[0208] 如图57所示,随着驱动杆140向着远侧方向进一步移动,驱动杆140继续向着远侧方向推动连接板174。 As shown in [0208] FIG. 57, as drive bar 140 is moved further in a distal direction, drive bar 140 continues to push connector plate 174 in a distal direction. 因为推杆156仍通过第二弹簧夹子157b选择性地连接于连机板174,所以推杆156被进一步向着远侧方向推进或拖动。 Since pusher bar 156 is still selectively by a second snap clip 157b connected to the connected board 174, the plunger 156 is further advanced or dragged in a distal direction. 然而,因为楔形板172的第三弹簧夹子157c被从连接板174的第二杆174c脱离,所以楔形板172不被向着远侧方向进一步推进或拖动。 However, since third snap clip 157c of wedge plate 172 is disengaged from the second shaft 174c of connector plate 174, so that wedge plate 172 is not further advanced or dragged in a distal direction.

[0209] 如图56A至图56C所示,随着推杆156向着远侧方向继续移动,推杆156的侧凹槽156f的近端接合推进板162的一对翼片162b,推杆156向着远侧方向推进或拖动推进板162。 [0209] As shown in FIGS. 56A to 56C, as pusher bar 156 continues to move in a distal direction, pusher pair of fins 162b side recesses 156f of the proximal end 156 engages the advancer plate 162, pusher bar 156 toward the advanced or dragged in a distal direction pusher plate 162.

[0210] 如图56B和图56C所示,随着推动板162向着远侧推进,弹簧夹子157d脱离近侧保持槽152m并接合形成于上壳体152a中的远侧保持槽152η。 [0210] As shown in FIG. 56B and FIG. 56C, as advancer plate 162 advanced distally, snap clip 157d departing from the proximal retaining grooves 152m and engages distal formed on the housing 152a of the holding groove 152η.

[0211] 如图57所示,驱动杆140向着远侧方向移动,直到滑动接头182的凸起182a选择性地平移至驱动杆140的细长狭槽140a中的最近侧位置。 As shown in [0211] FIG. 57, drive bar 140 moves toward the distal direction, the elongated proximal-most position in slot 140a 140 until projection 182a of slider joint 182 is selectively move the drive rod horizon.

[0212] 随着推杆156继续向着远侧方向移动,推杆156通过翼片162b继续向着远侧方向推动推进板162。 [0212] As the plunger 156 continues to move in a distal direction, pusher bar 156 continues to move through the fins 162b of advancer plate 162 in a distal direction pushed. 如图58所示,随着推进板162向着远侧方向移动,夹子输出器166的远侦U凸起166b被容纳夹子输出器166的远侧凸起166b的窗口162a的近侧边缘接合以便相对于夹子载体164向着远侧方向推动夹子输出器166,从而使该堆夹钳“C”推进增加的量。 As illustrated, as advancer plate 162 is moved in a distal direction, distal clip detect the U-166 166 distal protrusion 58 is accommodated 166b tab 166b of clip follower proximal window 162a for engaging opposite edges push the clip 164 clip carrier 166 in a distal direction, so that the stack of clips "C" to promote increased amount. 随着夹子输出器166向着远侧方向移动,使得其近侧凸起166c从夹子载体164的相对近侧窗口164a到夹子载体164的相对远侧窗口164a向远侧推进一个窗口164a。 As clip follower 166 is moved in a distal direction, such that proximal tab 166c of clip carrier opposite from the proximal window 164 of clip carrier 164 to 164a of a relatively distal window 164a advance distally window 164a.

[0213] 如图58至图60所不,随着推杆156向着远侧方向移动,支撑于推杆156上的第一弹簧夹子157a弹锁在上壳体152a的凸台152h上,因而将推杆156保持在向前的位置处。 [0213] As shown in FIGS. 60 to 58 do not, as pusher bar 156 is moved in a distal direction, pusher bar 156 is supported on a first snap clip 157a snap on the boss 152h of upper housing 152a, thus the push rod 156 is held at the position forward.

[0214] 此外,如图61所示,随着推杆156继续向着远侧方向移动,使得该堆夹钳“C”向着远侧方向移动。 [0214] Further, as shown in Figure 61, as pusher bar 156 continues to move in a distal direction, so that the stack of clips "C" moves toward the distal direction.

[0215] 如图62所示,随着推杆156向着远侧方向移动,其推动器156c继续向着远侧方向移动最远侧夹子“Cl”直到最远侧夹子“Cl”完全进入到钳口106的通道106a中。 [0215] FIG. 62, as pusher bar 156 is moved in a distal direction pusher 156c thereof continues to move in a distal direction, distal-most clip "Cl" until distal-most clip "Cl" completely into the jaws 106 of the channel 106a. 在操作中,推杆156的推动器156c在所述夹子“C”的形成期间与装入的夹子“C”的后跨部保持接触以便为其提供稳定性并将其保持在合适的位置。 In operation, pusher 156c of pusher bar 156 remains in contact with the clip "C" cross-section is charged during the forming of the clip "C" in order to provide stability and to hold it in place.

[0216] 如图63所示,随着驱动杆140进一步向着远侧方向移动,其肩部140c接触驱动通道168的最近端。 [0216] As shown in FIG 63, as drive bar 140 is moved further in the distal direction, which contacts the shoulder 140c of drive channel 168 nearest end. 这样,随着驱动杆140进一步向着远侧方向移动,驱动杆140向着远侧方向移动或推动驱动通道168。 Thus, as drive bar 140 is moved further in a distal direction, drive bar 140 in a distal direction to move or push drive channel 168.

[0217] 如图64所示,随着驱动通道168向着远侧方向移动,形成于驱动通道168的侧壁168b中的窗口168e的近侧边缘接触楔形板释放装置194的齿194c,使得楔形板释放装置194旋转。 Window [0217] As shown in FIG. 64, as drive channel 168 moves toward the distal direction, is formed on the side wall 168b of drive channel 168 in a proximal edge 168e of wedge plate release 194 contacting the teeth 194c, wedge plate such that release means 194 rotation. 随着楔形板释放装置194旋转,其槌194b挤压楔形板锁190的齿190e以将齿190e从倾斜凸耳152f的后方推出或撞出。 With the rotation of the wedge plate release 194, which hammer 194b pressing teeth 190e of wedge plate lock 190 to the tooth 190e out of the rear inclined ledge 152f or knocked. 在这种情况下,如图65所示,允许偏置构件192减压,从而向着近侧方向移动楔形板锁190。 In this case, as shown in Figure 65, the biasing member 192 allows the reduced pressure to a proximal direction moving wedge plate lock 190. 如图66所示,随着楔形板锁190向着近侧方向移动,因为楔形板172连接到楔形板锁190上,所以楔形板172向着近侧方向移动以使其远端172a从与钳口106退出脱离接合。 Shown in Figure 66, as wedge plate lock 190 is moved in a proximal direction, as wedge plate 172 is connected to the wedge plate lock 190, the wedge plate 172 in a proximal direction so as to move from a distal end 172a of the jaw 106 exit disengaged.

[0218] 如图58和图67至图69所示,因为推杆156通过第一弹簧夹子157a与凸台152h的连接而保持在远侧位置,所以随着驱动杆140进一步向着远侧方向移动,作用于连接板174的力使得第二弹簧夹子157b从连接板174的第一杆174b脱离,从而允许连接板174继续向着远侧方向移动。 [0218] FIG. 58 and FIG. 67 through FIG. 69, because the push rod 156 157a with boss 152h of the connector is held in position by a first spring clip distally, so as drive bar 140 is moved further in a distal direction , the forces acting on connector plate 174 such that the second snap clip 157b is disengaged from the first shaft 174b of connector plate 174, thereby allowing the connector plate 174 to continue to move in a distal direction.

[0219] 如图67A至图69A所示,在一个实施方式中,第二弹簧夹子157b的尖头的尖端可以配置成向外突出以便接合后上部壳体154的表面(参见图9),从而防止第二弹簧夹子157b从连接板174的第一杆174b的过早脱离。 [0219] FIG. 67A to FIG. 69A, in one embodiment, the tip of the second sub-spring clip prong 157b may be configured to project outwardly so as to engage the rear surface of the upper housing 154 (see FIG. 9), thereby prevents the second snap clip 157b from first stem 174b of connector plate 174 is disengaged prematurely. 在该实施方式中,凹槽可以形成于后部上壳体154的表面中,与第二弹簧夹子157b的尖头可能向外张开的位置一致,从而允许连接板174的第一杆174b脱离并继续向着远侧方向移动。 In this embodiment, the grooves may be formed on the rear surface of the housing 154 in accordance with the second clip 157b outwardly flared prongs possible position, allowing the first lever 174b of connector plate 174 from and continue to move in a distal direction.
