[0036] 结合图1和图7所示,在旋转旋钮3以通过钉砧拉杆13带动拉杆销131移动至第二槽1612远端的连接槽1613位置处时,所述保险块16在所述扭簧17的作用力下旋转,从而使得保险块16的第一竖直壁164和锁块15的第二竖直壁1522相抵持,同时所述拉杆销131相对移入第一槽1611近端的连接槽1613位置处;并且在此时,所述锁块15内的滑槽153和保险块16的第一槽1611沿壳体10轴向相对应。 When [0036] FIG. 1 and FIG. 7, in the rotary knob 3 through the anvil rod of the pin 13 causes the rod 131 to move the distal end of the second groove 1612 of the groove 1613 is connected position, the safety block 16 in the rotational biasing force of the torsion spring 17, the safety block so that the first vertical wall 164 and the locking block 15 of the second vertical wall 16 against the support 1522, while the opposite lever pin 131 into the proximal end of the first groove 1611 at the connection position of the groove 1613; and at this time, the locking slide 153 and the safety block housing 10 in the axial direction corresponding to a first slot 161,116 in the block 15.

[0037] 结合图2、图4、图7及图8所示,当继续旋转旋钮3时,钉站拉杆13带动拉杆销131继续移动,此时拉杆销131先自连接槽1613移入第一槽1611、再穿过缺口162及锁块15内侧的滑槽153。 [0037] in conjunction with FIGS. 2, 4, 7 and 8, when the knob 3 continues to rotate, the staple stop rod 13 causes the rod pin 131 continues to move, this time from the connecting rod pin 131 to 1613 into the first slot groove 1611, and then through the chute 162 and the notch 153 of the locking piece 15 inside. 上述在旋转旋钮3而使钉砧拉杆13带动拉杆销131自第二槽1612朝第一槽1611及缺口162和滑槽153中移动过程中,钉砧拉杆13朝远离钉仓组件的方向推动抵钉座组件2。 3 in the direction of the rotation of the knob causes the rod 13 of anvil rod 131 from the pin 1611 and 1612 toward the first groove 162 and the notch 153 during movement of the chute, the anvil rod 13 toward the second groove away from the staple cartridge assembly of the staple pushed against 2 seat assembly.

[0038] 当旋转旋钮3使得钉砧拉杆13移动至最大行程后,再反向旋转旋钮3,此时,钉砧拉杆13带动拉杆销131回退,使得拉杆销131穿过滑槽153及缺口162进入第一槽1611 ;在上述反向旋转旋钮3以带动钉砧拉杆13回退的过程中,所述抵钉座组件2被钉砧拉杆13带动逐渐靠近钉仓组件,以将需吻合、切割的组织拉入钉筒12内空腔并被抵钉座组件2和钉仓组件夹紧。 [0038] When rotation of the knob 3 so that the anvil moves the rod 13 to the maximum stroke, and then reverse rotation of the knob 3, this time, the anvil rod 13 causes the rod backoff pin 131, such that the pin 131 passes through the sliding rod 153 and the gap 162 into the first groove 1611; in the reverse rotation of the knob 3 so as to drive the anvil rod 13 during backoff, the anvil assembly 2 is driven by an anvil rod 13 gradually approaches the cartridge assembly, the need to match, cutting tissue pulled into the cavity 12 within the staple cartridge and anvil assembly and the cartridge assembly 2 clamped. 结合图2、图4及图9所示,当反向旋转旋钮3使钉砧拉杆13带动拉杆销131移入第一槽1611近端的连接槽1613内时,再继续反向旋转旋钮3,拉杆销131则会抵推连接槽1613近端的内壁,从而推动保险块16朝旋钮3方向移动,同时保险簧18被压缩;此时,若未按压击发把手4,则锁块15会在保险块16及扭簧17的拉动下朝旋钮3方向移动,同时锁块15的限位销151在壳体11的限位槽101内也朝旋钮3方向移动,即限位销151向壳体10的限位槽101的近端移动。 In conjunction with FIG. 2, FIG. 4 and FIG. 9, when the reverse rotation of the knob so that the anvil rod 3 causes the rod 13 connected to pin 131 moved into the groove 1613 of the proximal end of the first groove 1611, and then continue the reverse rotation of the knob 3, lever pin 131 will push against the inside wall of the proximal end of the slot 1613, thus promoting the safety block 16 to move toward the direction of the knob 3, spring 18 is compressed while the insurance; at this time, if not the pressing of the firing handle 4, the locking block 15 will be in the safety block 3 the knob 16 and moves in the pulling direction of the torsion spring 17, the stopper pin 151 while the locking block 15 is also moved in the direction of the knob 3 in the limiting groove 101 of the housing 11, i.e., the stopper pin 151 to the housing 10 limiting movement of the proximal end 101 of the slot. 再结合图10所示,当旋钮3通过拉杆13带动抵钉座组件2移至靠拢钉仓组件而夹紧组织(未图示)时,锁块15移动脱离击发把手4的抵持面431,即解除对击发把手4的限制,此时即可按下击发把手4进行钉仓组件内的吻合钉、环形切刀的击发。 Combined with Figure 10, when the knob 32 to move the cartridge assembly closer to the anvil assembly 13 by a rod driven to clamp tissue (not shown), locking block 15 is moved out of the firing handle 4314 of the abutting surfaces, i.e. to lift restrictions on the firing handle 4, in which case the firing handle 4 to press the staple cartridge assembly, the annular cutter firing. 在按下击发把手4的过程中,击发把手4抵持锁块15并使得锁块15在保险块16的配合下微幅旋转,此时,拉杆销131移入第二槽1612远端的连接槽1613中。 In the process of pressing the handle 4 of the firing, the firing handle 4 abuts against the lock so that the lock block 15 and block 15 slightly rotates in cooperation with the safety block 16, this time, the connection rod pin 131 into the groove of the second groove 1612 of the distal end 1613.

[0039] 结合图10及图1所示,当击发完成后松开击发把手4,此时压缩的保险簧18释放而推动保险块16朝远离旋钮3的方向移动而使得拉杆销131退回至初始状态。 [0039] and FIG. 1 in conjunction with FIG. 10, when the firing release the firing handle 4 is completed, then release the compressed spring 18 pushes the insured safety block 16 in a direction away movement of the knob 3 so that the pin 131 is returned to the initial rod status.

[0040] 由以上可见,本发明圆管型吻合器100通过设置保险机构,使得在旋钮3未旋转至击发位置时,击发把手4与保险机构的锁块15相抵持,从而限制击发把手4的操作;当旋转旋钮3至击发位置时,通过钉砧拉杆13上的拉杆销131拉动保险块16、进而带动锁块15移动而移除对击发把手4的限制,使得击发把手4可以进行击发;从而可以有效防止误击发的发生,且简化了圆管型吻合器100的使用步骤,使得手术操作更加简单方便,进而有效避免因误击发而造成的医疗事故。 [0040] seen from the above, the present invention stapler tube 100 by providing a safety mechanism so that when the knob 3 is not rotated to the firing position, the firing handle 4 and the lock block 15 resists against the insurance institutions, thus limiting the firing handle 4 operation; when the rotation of the knob 3 to the firing position, the lever pin 131 on the anvil 13 to pull the safety block lever 16, locking block 15 is moved so as to drive the firing handle to remove restrictions on the 4, 4 may be such that the firing of the firing handle; thereby effectively preventing the occurrence of erroneous firing, and simplifies the use of steps stapler tube 100, so that the surgical procedure more simple and convenient, thus effectively prevent erroneous firing due to malpractice caused.
