如图1-3所示，本发明一实施例提供一种缝合枪手柄10，能够与枪杆60、枪头70以及缝合针80配合使用完成半月板的缝合。缝合枪包括前枪柄100、后枪柄200、扳机300以及穿入接头。前枪柄100上开设安装孔110和穿入孔120，安装孔110用于安装枪杆60，穿入孔120和安装孔110连通，穿入孔120和安装孔110允许缝合针80沿插入方向依次穿入。后枪柄200活动设置于前枪柄100靠近穿入孔120的一侧，后枪柄200活动时能够推动缝合针80沿插入方向移动。扳机300活动设置于前枪柄100，扳机300活动时能够驱动与其传动连接的枪头70动作。穿入接头设置于穿入孔120远离安装孔110的一端，穿入接头允许缝合针80穿入，穿入接头能够连接洗消管路。上述缝合枪手柄10，前枪柄100、后枪柄200以及扳机300能够与枪杆60以及枪头70配合实现待缝合组织的缝合修复，同时穿入接头不仅能够允许缝合针80穿入，还能够连接洗消管路，进而将清洗、消毒用的液体引入穿入孔120、安装孔110以及固定安装在安装孔110内的枪杆60，实现了缝合枪手柄10以及组织缝合枪1的有效清洗或消毒，可在缝合修复手术前和/或手术后分别进行清洗、消毒，进而保证半月板等软骨组织缝合修复过程的顺利进行。As shown in FIGS. 1-3 , an embodiment of the present invention provides a
需要说明的是，上述实施例中的插入方向指的是缝合针80插入缝合枪手柄10中穿入孔120以及安装孔110的方向，也是在执行缝合动作时后枪柄200推动缝合针80移动的方向；并且当安装孔110与穿入孔120同轴设置时，插入方向还是安装孔110以及穿入孔120的延伸方向；对应图1中示例的缝合枪手柄10以及组织缝合枪1，插入方向大致是水平向左的方向。穿入接头的作用是允许缝合针80插入同时能够连接洗消管路。可选的，穿入接头可以是连接带也可以是连接管。作为一种可实现的方式，如图2-4所示，穿入接头包括穿入连接管400，穿入连接管400的一端可拆卸的固定设置于穿入孔120远离安装孔110的一端。穿入连接管400远离穿入孔120的另一端具有翻边410，翻边410沿穿入连接管400的径向向外翻折。穿入连接管400可拆卸的安装在穿入孔120的一端，允许便捷的拆卸和更换，并且可以仅在需要清洗或消毒时将穿入连接管400安装到穿入孔120，也可以一直将穿入连接管400安装在穿入孔120的一端。并且穿入连接管400上的翻边410能够与洗消管路形成过盈配合，不仅起到密封的作用，还能够防止脱落。It should be noted that the insertion direction in the above embodiment refers to the direction in which the suture needle 80 is inserted into the
可选的，穿入连接管400与穿入孔120之间的可拆卸配合可以是卡接、螺纹连接或者利用可拆卸的中间连接件。在本发明一实施例中，如图2-4所示，穿入连接管400以螺纹连接的方式与穿入孔120远离安装孔110的一端可拆卸的固定连接。螺纹连接不仅具有连接稳固、便于拆装的作用，而且螺纹连接自身具有良好的密封作用，能够有效防止穿入连接管400与穿入孔120的内壁之间溢出洗消液体。需要说明的是，在上述各个实施例中对于前枪柄100、后枪柄200、扳机300以及穿入接头的结构形式并不做具体的限制，只要能够实现其各自对应的功能即可。作为一种可实现的方式，如图1-4所示，前枪柄100大致呈曲率较大的圆弧杆状，后枪柄200大致呈曲率较小的圆弧杆状，并且后枪柄200的底端转动安装在前枪柄100的底端，进而后枪柄200转动时，后枪柄200的顶端靠近或者远离前枪柄100的顶端。同时安装孔110和穿入孔120也同轴开设在前枪柄100的顶端，允许后枪柄200驱动伸入穿入孔120和安装孔110的缝合针80沿插入方向移动。进一步，安装孔110、穿入孔120以及穿入连接管400的截面分别呈圆形，扳机300呈圆弧杆状。在其它的实施例中，前枪柄100、后枪柄200、扳机300以及穿入接头还可以是其他可以实现的结构样式。Optionally, the detachable cooperation between the penetrating
在半月板的缝合修复过程中，如图5所示，需要先驱动枪头70夹紧待缝合的半月板，然后通过后枪柄200驱动缝合针80携带缝合线刺入半月板。在本发明一实施例中，如图2-6所示，缝合枪手柄10还包括锁定结构500。扳机300活动时具有夹紧位置和释放位置，扳机300活动至夹紧位置时能够驱动与其传动连接的枪头70夹紧待缝合的组织(比如半月板)，扳机300活动至释放位置时驱动或者允许与其传动连接的枪头70松开待缝合的组织。锁定结构500设置于前枪柄100，锁定结构500能够维持扳机300处于夹紧位置，或者锁定结构500能够允许扳机300运动至释放位置。锁定结构500维持扳机300处于夹紧位置，进而能够实现枪头70对半月板的持续夹紧，无需操作者持续的施加夹紧力，节省了操作者的操作难度。操作者使用本实施例提供的缝合枪手柄10时可以更加专心的驱动后枪柄200动作。During suture repair of the meniscus, as shown in FIG. 5 , it is necessary to drive the
作为一种可实现的方式，如图2-5所示，锁定结构500包括锁定轴510和弹性锁件520，锁定轴510的中部转动设置于前枪柄100，锁定轴510的一端能够与活动至夹紧位置的扳机300卡接。弹性锁件520固定设置于前枪柄100，弹性锁件520压紧锁定轴510远离扳机300的另一端，弹性锁件520用于保持锁定轴510与扳机300之间的卡接关系(类似于自锁)，锁定轴510远离扳机300的另一端受到扰动时允许扳机300活动至释放位置。锁定轴510配合弹性锁件520的结构形式具有结构简单、稳固锁定的优点。进一步，如图2-4所示，弹性锁件520包括弹性锁片，弹性锁片的一端固定设置于前枪柄100，弹性锁片的另一端压紧锁定轴510远离扳机300的另一端。锁定轴510靠近扳机300的一端具有楔形钩521，扳机300转动设置于前枪柄100，扳机300上具有多个楔形齿511，多个楔形齿511沿扳机300的转动方向分布，扳机300转动至夹紧位置的过程中，楔形钩521能够与任一楔形齿511卡合。本实施例中扳机300和锁定轴510之间形成类似棘爪和棘轮的组合形式，在操作者不断搬动扳机300的过程中，锁定轴510能够将扳机300锁定在任一当前的位置，进而允许操作者根据半月板的厚薄情况调整扳机300的转动位置。在其它的实施例中，弹性锁件520还可以是扭簧形式，锁定轴510对扳机300的释放由操作人员按压锁定轴510的另一端实现。As an achievable way, as shown in FIGS. 2-5 , the locking
在本发明一实施例中，如图2-6所示，后枪柄200转动设置于前枪柄100，后枪柄200能够与缝合针80的针座810沿插入方向固定连接。扳机300与前枪柄100之间设置第一复位件140，第一复位件140在扳机300活动至夹紧位置的过程中受压，第一复位件140用于驱动扳机300活动至释放位置。前枪柄100和后枪柄200之间设置第二复位件130，第二复位件130在后枪柄200向靠近前枪柄100方向推动缝合针80时受压，第二复位件130用于驱动后枪柄200向远离前枪柄100方向拉出缝合针80。第一复位件140和第二复位件130实现了扳机300以及后枪柄200的自动复位，降低了半月板缝合修复过程的复杂程度。作为一种可实现的方式，第一复位件140和第二复位件130可以是弹簧、橡胶或者其他弹性结构。如图3-6所示，缝合针80的针座810上具有固定柱811，后枪柄200的顶端开设顶端开口的固定槽210，固定柱811能够从固定槽210的顶端放入固定柱811中，进而在后枪柄200转动的过程中，缝合针80与后枪柄200的顶部沿插入方向(大致水平方向)保持位置固定。进一步，后枪柄200上开设通孔，在不明显降低后枪柄200结构强度的前提下降低缝合枪手柄10的重量。同时在前枪柄100上开设弧形的导向槽150，在后枪柄200上设置导向柱220，导向柱220插入导向槽150中，进而保持后枪柄200相对于前枪柄100的稳定转动。In an embodiment of the present invention, as shown in FIGS. 2-6 , the rear gun handle 200 is rotatably disposed on the
如图1-6所示，本发明一实施例还提供一种组织缝合枪1，包括枪杆60、枪头70和上述各个实施例中任一项所述的缝合枪手柄10，枪杆60的一端固定设置于安装孔110，枪头70设置于枪杆60远离前枪柄100的一端，枪杆60固定设置于安装孔110时，枪头70与扳机300传动连接。上述组织缝合枪1中，前枪柄100、后枪柄200以及扳机300能够与枪杆60以及枪头70配合实现待缝合组织的缝合修复，同时穿入接头不仅能够允许缝合针80穿入，还能够连接洗消管路，进而将清洗、消毒用的液体引入穿入孔120、安装孔110以及固定安装在安装孔110内的枪杆60，实现了缝合枪手柄10以及组织缝合枪1的有效清洗或消毒，可在缝合修复手术前和/或手术后分别进行清洗、消毒，进而保证半月板等软骨组织缝合修复过程的顺利进行。As shown in FIGS. 1-6 , an embodiment of the present invention further provides a
枪杆60的作用是连接枪头70和缝合枪手柄10，可以理解的，枪杆60呈中空的结构，能够允许缝合针80由缝合枪手柄10穿入并且由枪头70刺入半月板。枪头70的作用是夹紧半月板并且引导缝合针80刺入半月板。作为一种可实现的方式，如图6-8所示，枪头70呈鸭嘴夹形式，枪头70包括上夹板710和下夹板720，下夹板720固定设置于枪杆60远离前枪柄100的一端，上夹板710转动设置于下夹板720，上夹板710与扳机300传动连接，扳机300活动时能够驱动上夹板710转动进而夹紧待缝合的组织。下夹板720上具有引导部721，上夹板710上开设穿出孔711，后枪柄200推动缝合针80沿插入方向移动时，引导部721引导缝合针80的针头830由穿出孔711穿出，缝合针80的针头830由穿出孔711穿出后能够刺入被夹紧的半月板中，同时缝合针80的针头830携带缝合线穿过半月板，为下一步继续缝合或者打结奠定基础。鸭嘴夹形式的枪头70具有结构成熟、便于缝合的优点。The function of the
缝合针80的针头830携带缝合线穿过半月板后，操作者减小对后枪柄200的驱动力，后枪柄200的顶端远离前枪柄100运动，进而缝合针80在后枪柄200的带动下沿插入方向的反向运动，缝合针80的针头830沿刺入的路径缩回枪头70内。在缝合针80的针头830缩回枪头70时，需要避免缝合线随针头830一起缩回枪头70内。在本发明一实施例中，如图6-8所示，枪头70还包括压合板730和压合扭簧740，压合板730转动设置于上夹板710，压合板730转动时遮蔽穿出孔711或者避让穿出孔711，压合扭簧740设置于压合板730和上夹板710之间，压合扭簧740用于驱动压合板730转动至遮蔽穿出孔711的位置。压合板730的外周缘具有挂齿731，压合板730转动至遮蔽穿出孔711的位置时，挂齿731配合上夹板710咬合随针头830伸出穿出孔711的缝合线。在本实施例中，压合板730在压合扭簧740的作用下遮蔽穿出孔711，缝合针80的针头830伸出穿出孔711时能够将压合板730抵接，并且驱动压合板730转动进而允许缝合针80的针头830穿出。当缝合针80的针头830缩回枪头70内时，压合板730上的挂齿731咬紧缝合线，进而保持缝合线穿过半月板，为下一步继续缝合或者打结奠定基础。After the
作为一种可实现的方式，引导部721包括开设于下夹板720上的翘曲滑槽，翘曲滑槽开设于下夹板720靠近上夹板710的一侧，翘曲滑槽由下夹板720指向穿出孔711。上夹板710与扳机300之间通过连接杆传动连接，并且连接杆也可以设置在枪杆60内；具体的，连接杆与扳机300的顶部连接，连接杆用于将扳机300顶部的转动转化为上夹板710的转动。翘曲滑槽能够有效引导缝合针80的针头830改变水平的前进方向进而沿竖直方向由穿出孔711穿出。进一步，翘曲滑槽的内壁是圆滑曲面，比如圆弧面。在其它的实施例中，引导部721还可以是导向管或者导向轮。在本发明一实施例中，组织缝合枪1还包括缝合针80，如图5-6及图9所示，缝合针80能够活动穿设于枪头70、枪杆60以及前枪柄100。作为一种可实现的方式，缝合针80包括针座810、针杆820和针头830，针杆820的一端固定设置于针座810，针头830固定设置于针杆820远离针座810的另一端。针座810能够与后枪柄200沿插入方向固定连接，针杆820和针头830能够活动穿设于枪头70、枪杆60或者前枪柄100。所述针头830能够发生弯曲弹性变形，进而避免针头830穿过翘曲滑槽时被损坏。同时针头830远离针杆820的一端开设勾线槽831，勾线槽831能够携带缝合线穿过半月板。As an achievable way, the
