需要理解的是，本文所用术语“近侧”和“远侧”是相对于操纵吻合器的手柄的临床医生而言的。术语“近侧”是指靠近临床医生的部分，术语“远侧”则是指远离临床医生的部分。即手柄为近侧，钳口组件为远侧，如某个零部件的近侧端表示相对靠近手柄的一端，远侧端则表示相对靠近钳口组件的一端。术语“上”“下”以钳口组件的抵钉座和钉仓座的相对位置为参考，具体的，抵钉座在“上”，钉仓座在“下”。然而，吻合器可以在许多方向和位置使用，因此这些表达相对位置关系的术语并不是受限和绝对的。
图1至图24示出本申请的第一实施例的一种用于外科器械的钳口组件驱动装置，其用于控制钳口组件的锁定、解锁和转动。钳口组件驱动装置包括：座体10、转向件20、运动件30以及驱动件40。转向件20的远端与钳口组件200连接，以使得转向件20与钳口组件200同步锁定、解锁和转动，转向件20的近端与座体10可枢转地连接。运动件30与转向件20可运动地连接，运动件30具有锁定位置和解锁位置。驱动件40驱动运动件30从锁定位置朝向远侧运动至解锁位置；在锁定位置时，运动件30与座体10配合以锁定转向件20；在解锁位置时，运动件30与座体10分离以解锁转向件20，驱动件40朝向远侧运动以通过运动件 30驱动转向件20转动。
由上可知，本实施例的运动件与转向件可运动地连接，运动件能够在驱动件的作用下从锁定位置运动至解锁位置，在锁定位置时，运动件与座体配合以锁定转向件；在解锁位置时，运动件与座体分离以解锁转向件，并且在驱动件的作用下驱动转向件转动。也就是说，本实施例的用于外科器械的钳口组件驱动装置通过运动件与座体配合及分离，实现转向件的锁定与解锁，进而实现钳口组件的锁定和解锁，相对于现有技术在远离钳口组件的旋钮端设置复杂的锁定结构来实现钳口组件的锁定和解锁，能够有效地锁定钳口组件；而且本实施例的钳口组件驱动装置的零件较少，整体结构简单紧凑，钳口组件锁定及转向的可靠性高。
在本实施例中，运动件30与转向件20滑动配接，在锁定位置时，运动件30的远端与转向件20的近端间隔设置；在解锁位置时，运动件30的远端与转向件20的近端抵接。运动件30与转向件20滑动配接使得在运动件30在锁定位置时，通过运动件30与座体10的配接实现转向件20的锁定进而实现对钳口组件的锁定；同时，在锁定位置时，运动件30的远端与转向件20的近端间隔设置，提供了运动件30的移动空间，使得运动件30能够在驱动件40的作用下从锁定位置朝向远侧运动至解锁位置。而在解锁位置时，运动件30的远端与转向件20的近端抵接，一方面使得运动件30在驱动件40的作用下驱动转向件20的转动更加平稳，也即使得钳口组件的转动更加平稳；另一方面，运动件30的远端与转向件20的近端抵接后，运动件30的平移运动被限制，在驱动件40的作用下和转向件20一起转动，减少了能量的损耗，使得操作更加省力顺畅。
在本实施例中，运动件30与转向件20可移动地连接，驱动件40驱动运动件30从锁定位置朝远侧移动至解锁位置。具体地，钳口组件驱动装置还包括运动引导件60，运动件30被运动引导件60引导，在锁定位置和解锁位置之间运动。上述的运动引导件60能够保证运动件30的移动方向。更为具体地，运动引导件60包括滑轨结构61，驱动件40驱动运动件30沿滑轨结构61的延伸方向从锁定位置朝远侧运动至解锁位置。这样的设计，一方面实现运动件30与转向件20可移动地连接，运动件30通过滑轨结构61对转向件20进行限位，使得在运动件30在锁定位置时，通过与座体10的配合实现转向件20的锁定进而实现对钳口组件的锁定；另一方面能够对运动件30的运动起到导向的作用，增大运动件30和转向件20的接触面积，使得运动件30的移动，以及运动件30和转向件20的转动都较为平稳，同时还简化了结构，提高可靠性。
滑轨结构61包括滑块611和滑槽612，滑块611和滑槽612滑动配合，滑块611和滑槽 612中的一个设置于转向件20，滑块611和滑槽612中的另一个设置于运动件30。具体地，在本实施中，滑块611设置在转向件20上，滑槽612设置在运动件30上。滑块611包括滑块主体6111及设置在滑块主体6111上的凸沿6112，滑槽612包括与滑块主体6111滑动配合的滑槽主体段6121以及与凸沿6112配合的第一限位台阶段6122。第一限位台阶段6122和凸沿6112的配合能够保证滑块611与滑槽612滑动配合的稳定性。滑块611还包括设置在滑块主体6111的端部的凸起部6113，凸起部6113朝向运动件30延伸，滑槽612还包括与凸起部6113配合的第二限位台阶段6123。同样的第二限位台阶段6123和凸起部6113抵接配合，能够进一步提高转向件20的稳定性，也保证了滑轨结构61的限位效果。同时，在凸起部6113远离转向件20的端部设置有圆弧过渡，这样能够防止出现卡死的情况，使得滑块611与滑槽612的滑动配合更加顺畅。进一步地，滑块611设置于转向件20的近端；座体10的远端设置有第一延伸部11，运动件30与第一延伸部11叠置，这样的设置能够提高空间利用率，使得整体结构更加紧凑。
钳口组件驱动装置还包括偏压件，在锁定位置时，偏压件向近端偏压运动件30以使运动件30保持在锁定位置，当运动件30被驱动从锁定位置运动至解锁位置时，偏压件被压缩蓄能。偏压件为弹性件。在本实施例中，偏压件为第一偏压件50。即在锁定位置时，第一偏压件50向近端偏压运动件30以使运动件30保持在锁定位置，当运动件30被驱动从锁定位置移动至解锁位置时，第一偏压件50被压缩蓄能。驱动件40在驱动运动件30运动时，需要克服第一偏压件50对运动件30施加的力，这样使得在操控钳口组件驱动装置时，更具有阻尼感，即提升了医生操作手感；在没有外力施加于运动件30时，运动件30能够在第一偏压件50的作用下由解锁位置朝近侧移动至锁定位置。具体地，第一偏压件50的远端与转向件20连接，第一偏压件50的近端与运动件30连接。更为具体地，在本实施例中，第一偏压件50是设置在运动件30和转向件20之间的，这样的设计使得空间利用率高，结构紧凑，且便于安装。优选地，运动件30设置有第一安装部31和第二安装部32，转向件20设置有第三安装部，第一偏压件50为扭簧51，扭簧51包括螺旋部511和连接在螺旋部511两侧的第一扭簧臂512和第二扭簧臂513，螺旋部511设置于第三安装部，第一扭簧臂512和第一安装部31配合，第二扭簧臂513和第二安装部32配合。扭簧51的结构简单，成本较低，并且复位的效果较好，第一扭簧臂512和第二扭簧臂513能够稳定地与第一安装部31和第二安装部32配合，进而提高了稳定性。在图中未示出的实施例中，偏压件包括其它形式的弹性件，例如橡胶件或者弹簧，橡胶件或者弹簧可压缩变形并具有复位的能力，橡胶件或者弹簧设置在运动件和转向件之间。
请参阅图1至图20，在运动件30转动时，第一扭簧臂512和第二扭簧臂513会发生弯折。此时第一扭簧臂512与第一安装部31的配合可能变成点接触，第二扭簧臂513与第二安装部32的配合也可能变成点接触，这样的接触方式不稳定，并容易使得第一扭簧臂512或者第二扭簧臂513损坏。为了避免上述的情况发生，在本实施例中，第一安装部31包括第一接触面，第二安装部32包括第二接触面，第一接触面和第二接触面均倾斜设置，优选地，第一接触面和第二接触面之间的夹角在5°至30°之间，第一接触面和第二接触面之间的距离由转向件20至座体10的方向上逐渐减小。上述的设置在第一扭簧臂512发生折弯时，能够与第一接触面实现线接触，第二扭簧臂513发生折弯时，能够与第二接触面实现线接触，即接触面积更大，因此能够使得运动件30转动的过程更加稳定。在图中未示出的实施例中，第一接触面上设置有第一限位槽，第二接触面上设置有第二限位槽，第一扭簧臂卡设在第一限位槽内，第二扭簧臂卡设在第二限位槽内，这样能够使得钳口组件转动的过程也较为稳定。
座体10包括第一本体12，第一本体12设置有第一锁定件121；运动件30包括第二本体34，第二本体34设置有第二锁定件341，第一锁定件121和第二锁定件341配合以实现运动件30与座体10的锁定。第一锁定件121和第二锁定件341能够有效地实现座体10和运动件30的锁定。由上述可知，运动件的运动过程包括移动和转动，在转动时，为了避免运动件与其他结构发生干涉，在本实施例中，第一本体12朝向第二本体34的一侧设置有弧形凹部，第二本体34朝向第一本体12的一侧设置有弧形凸部。弧形凹部上设置有第一锁定件121，弧形凸部上设置有第二锁定件341。弧形凹部和弧形凸部能够更好地配合进行转动，并能够避免弧形凸部与其他结构发生干涉或者卡死。第一锁定件121和第二锁定件341能够锁定运动件30和座体10之间的位置，保证钳口组件转动角度后能够稳定地固定在该角度处。第一锁定件121和第二锁定件341中的一个包括第一凸齿，第一锁定件121和第二锁定件341中的另一个包括第一齿槽。具体地，在本实施例中，第一凸齿设在第二本体上，第一齿槽设在第一本体上，第一凸齿和第一齿槽插接配合以实现运动件30角度的锁定。第一凸齿的端部设置有锥形面，为了与第一凸齿的配合，第一齿槽上也设置有扩口面，在本实施例中的第一凸齿为一个，第一齿槽为多个。
钳口组件驱动装置的驱动件40包括转向旋钮41和传动机构42；传动机构42与运动件30连接，转向旋钮41转动以驱动传动机构42运动，从而驱动运动件30运动。这样的设置结构较为简单，同时便于操作。具体地，传动机构42包括主动件421、与运动件30连接的从动件422，从动件422由主动件421驱动，主动件421由转向旋钮41驱动。更为具体地， 从动件422包括第一驱动杆4221和第二驱动杆4222，运动件30分别与第一驱动杆4221和第二驱动杆4222连接，主动件421驱动第一驱动杆4221和第二驱动杆4222一前一后运动。上述的第一驱动杆4221和第二驱动杆4222一前一后运动能够有效地驱动运动件30从锁定位置朝远侧移动至解锁位置。在图中未示出的实施例中，从动件也可以为驱动绳，如钢丝绳等，在此不作限制。主动件421包括第一主动杆4211和第二主动杆4212，第一主动杆4211与第一驱动杆4221连接，第二主动杆4212与第二驱动杆4222连接。驱动件40还包括固定设置于外科器械的机体内的压块100，第一主动杆4211和第二主动杆4212均包括第一定位端和第二定位端，第二定位端为弯折段104，该弯折段104***至压块100内，并与其铰接。同时，在转向旋钮41的底部设置有安装槽，第一主动杆4211和第二主动杆4212的第一定位端间隔地***至安装槽内。由于压块100的存在，在转向旋钮41作用下，第一主动杆4211和第二主动杆4212的第一定位端分别相对各自的第二定位端沿前后方向摆动，进而驱动第一驱动杆4221和第二驱动杆4222一前一后运动。运动件30包括第一抵接面35和第二抵接面36，第一驱动杆4221前进时与第一抵接面35抵接配合，第二驱动杆4222前进时与第二抵接面36抵接配合。第一抵接面35和第二抵接面36的设置能够使得第一驱动杆4221和第二驱动杆4222的驱动更加稳定。
如图7和图8所示，初始状态时，在运动件30位于锁定位置时，运动件30的第一凸齿与座体10上的第一齿槽啮合以锁定转向件20，进而使得钳口组件200锁定。当操作转向旋钮41驱动传动机构42时，运动件30在传动机构42的第一驱动杆4221或者第二驱动杆4222的推动下朝远侧移动至解锁位置，第一凸齿和第一齿槽脱离，转向件20被解锁。在此过程中，扭簧51被压缩蓄能，如图9和图10所示。当第一凸齿脱离第一齿槽后，在第一驱动杆4221或者第二驱动杆4222的驱动下，运动件30驱动转向件20绕座体10转动(座体10和转向件20之间设置有枢转件以实现座体10和转向件20的枢转连接，枢转件包括圆孔和圆柱)，而转向件20与钳口组件的近端连接，因此可以实现钳口组件的转动，如图11和图12所示。可以理解地是，运动件30在第一驱动杆4221作用下驱动转向件20绕第一方向转动，运动件30在第一驱动杆4221作用下驱动转向件20绕第二方向转动，第一方向和第二方向相反，以实现钳口组件双向转动。当钳口组件转动到所需要的角度时，停止驱动第一驱动杆4221和第二驱动杆4222，此时扭簧51开始释放弹性势能，扭簧51两侧的第一扭簧臂512和第二扭簧臂513推动运动件30两侧的第一安装部31和第二安装部32，使运动件30朝近侧移动至锁定位置，此时第一凸齿与第一齿槽重新啮合以重新锁定转向件20，如图13和图14所示。
结合图25至图44，为本申请的第二实施例，与第一实施例相同，本实施例涉及一种用 于外科器械的钳口组件驱动装置。本实施例与第一实施例的区别在于，运动件30与转向件20可枢转地连接，运动件30在驱动件40的作用下从锁定位置朝远侧枢转运动至解锁位置；当运动件30运动至解锁位置时，在驱动件40作用下驱动转向件转动，进而实现钳口组件的转动。其中“朝远侧枢转运动”是指运动件的远端点A在锁定位置时在水平面的投影为A1，在枢转运动过程中其在水平面的投影A2相对于A1从近侧朝远侧偏移。
为了实现运动件30和转向件20的枢转连接，在本实施例中，运动件30和转向件20之间设置有枢转结构70。枢转结构可以为孔轴式、柱孔式等，在本实施中，采用柱孔式的，具体地，枢转结构70包括枢转孔71和枢转柱72，枢转柱72***至枢转孔71内，枢转柱72和枢转孔71中的一个设置于转向件20上，枢转柱72和枢转孔71中的另一个设置于运动件30上。上述的设置能够有效地降低结构的复杂度，并且实现枢转连接。同时，上述的设置能够有效地保证枢转柱72的结构强度，进而提高使用寿命。在本实施例中，用于外科器械的钳口组件驱动装置还包括嵌套结构80，嵌套结构80设置于转向件20和运动件30之间，上述枢转结构70设置于嵌套结构80之间。具体地，转向件20包括凸块21，运动件30包括凹槽37，凸块21***至凹槽37内，凸块21和凹槽37形成嵌套结构80。凸块21和凹槽37的结构简单，便于设置。在本实施例中，枢转孔71设置于转向件20的凸块21上，枢转柱72设置于运动件30的凹槽37内，更为具体地，枢转孔71为半孔，枢转柱72包括相互连接的弧形段721、平面段722以及连接段723，弧形段721位于半孔内，平面段722与座体10抵接。这样的设计一方面便于运动件30与转向件20的安装，另一方面运动件30的运动更加稳定。
为了防止运动件30从锁定位置朝远侧枢转运动至解锁位置的过程中因空间的限制而与其他部件发生干涉，运动件30的中部的厚度大于运动件30的远端和运动件30的近端的厚度。
本实施例中，运动件30设置有第二锁定件341，座体10上设置有第一锁定件121，运动件30在锁定位置时，第一锁定件121和第二锁定件341插接配合以锁定转向件20。。第一锁定件121和第二锁定件341中的一个包括第二凸齿，第一锁定件121和第二锁定件341中的另一个包括第二齿槽，运动件30从锁定位置枢转运动至解锁位置时，第二凸齿和第二齿槽分离以解锁转向件20。第二凸齿和第二齿槽的结构简单，锁定效果好。具体地，本实施例中，第一锁定件121包括第二齿槽，第二锁定件341包括第二凸齿。第二凸齿设置于运动件30的近端，第二齿槽设置于座体10的远端。第二凸齿为一个，第二齿槽为多个。当然，第二凸齿和第二齿槽均可以为多个，或者第二凸齿为多个，第二齿槽为一个。
钳口组件驱动装置还包括偏压件，在本实施例中，偏压件为第二偏压件90，在锁定位置时，第二偏压件90向近端偏压运动件30以使运动件30保持在锁定位置，当运动件30被驱 动从锁定位置枢转运动至解锁位置时，第二偏压件90被压缩蓄能。第二偏压件90的设置能够为运动件30的复位提供能量。在没有外力施加于运动件30时，运动件30能够在第二偏压件90的作用下由解锁位置朝近侧枢转运动至锁定位置。同样的，在本实施例中，第二偏压件90为扭簧，包括螺旋部和连接在螺旋部两侧的第一扭簧臂和第二扭簧臂，运动件30设置有第一安装部31和第二安装部32，转向件20设置有第三安装部，第一扭簧臂和第二扭簧臂分别与第一安装部31和第二安装部32抵接配合，螺旋部设置于第三安装部。上述的第一安装部31和第二安装部32能够与驱动件40进行配合，进而使得驱动件40对运动件30进行驱动时，运动件的枢转运动更加稳定。优选地，第一安装部31和第二安装部32均为圆锥体，第一安装部31和第二安装部32靠近座体10的第一端的尺寸小于第一安装部31和第二安装部32远离座体10的第一端的尺寸。上述的设置增大了运动件30枢转运动的力臂，使得医生操作转动旋钮驱动驱动件40，进而驱动运动件30运动时更加省力，产品体验更好。
如图26至图28所示，初始状态时，在运动件30位于锁定位置时，运动件30的第二凸齿与座体10上的第二齿槽啮合以锁定转向件20，进而使得钳口组件200锁定。当操作转向旋钮41驱动传动机构42时，运动件30在从动件422的作用下朝远侧枢转运动至解锁位置，第二凸齿和第二齿槽脱离，转向件20被解锁。在此过程中，第二偏压件90蓄能，如图29至图32所示。当第二凸齿脱离第二齿槽后，在从动件422的驱动下，运动件30驱动转向件20绕座体10转动，而转向件20与钳口组件的近端连接，因此实现钳口组件的转动，如图33至图35所示。可以理解地是，运动件30在第一驱动杆4221作用下驱动转向件20绕第一方向转动，运动件30在第一驱动杆4221作用下驱动转向件20绕第二方向转动，第一方向和第二方向相反，以实现钳口组件双向转动。当钳口组件转动到所需要的角度时，停止驱动从动件422，此时第二偏压件90开始释放弹性势能，使运动件30朝向近侧枢转运动至锁定位置，此时第二凸齿与第二齿槽重新啮合以重新锁定转向件20，如图36至图39所示。
本申请还提供了第三实施例，与第一实施例、第二实施例相同，本实施例涉及一种用于外科器械的钳口组件驱动装置，用于控制钳口组件的转动和锁定。在本实施例中，钳口组件驱动装置包括座体10、转向组件、驱动件40以及偏压件；座体10与外科器械的机体连接，转向组件的远端与钳口组件200连接，以使得转向组件与钳口组件200同步锁定、解锁和转动，转向组件的近端与座体10可枢转连接；转向组件具有锁定状态和解锁状态，转向组件被驱动件40驱动以使其从锁定状态转换为解锁状态，所述偏压件偏压转向组件使其从解锁状态转换为锁定状态；在锁定状态时，偏压件向近侧偏压转向组件以使转向组件与座体10锁定配合；在解锁状态时，转向组件在驱动件40的作用下驱动钳口组件转动，偏压件被 压缩蓄能。本实施的用于外科器械的钳口组件驱动装置，相对于现有技术在远离钳口组件的旋钮端设置复杂的锁定结构来实现钳口组件的锁定和解锁，能够有效地锁定钳口组件；而且本实施例的钳口组件驱动装置的零件较少，整体结构简单紧凑，钳口组件锁定及转向的可靠性高；
具体地，转向组件包括转向件20和运动件30，运动件30与转向件20可运动地连接，转向件20的远端与钳口组件200连接，以使得转向件20与钳口组件200同步锁定、解锁和转动，转向件20的近端与座体10可枢转连接；运动件30具有锁定位置和解锁位置；述驱动件40驱动运动件30从锁定位置朝远侧运动至解锁位置，从而使得转向组件从锁定状态转换为解锁状态；偏压件偏压运动件30使其从解锁位置朝近侧运动至锁定位置，从而使得转向组件从解锁状态转换为锁定状态；在锁定位置时，偏压件偏压运动件30以使运动件30与座体10配合以将转向件20锁定；在解锁位置时，运动件30与座体10分离以解锁转向件20，运动件30在驱动件40的作用下驱动转向件20转动。其中，运动件30与转向件20可移动地连接，运动件30被驱动件40驱动从锁定位置朝远侧移动至解锁位置，具体实现方案同第一实施例；或者运动件30与转向件20可枢转地连接，运动件30被驱动件40驱动从锁定位置朝远侧枢转运动至解锁位置，具体实现方案同第二实施例。关于转向件20和运动件30、驱动件40以及偏压件的具体结构，相互之间的连接关系以及运动关系等，也均同上述的第一实施例或者第二实施例，此处不再赘述。
