Description

内窥镜子宫颈口捆扎系统 技术领域
本发明涉及一种腔镜手术器械,特别是用于腔镜手术中内窥镜子宫颈口捆扎系统。
背景技术
随着腔镜技术的发展,越来越多的手术在腔镜手术下完成,包括非常多的恶性肿瘤手术也是在腔镜下完成,其中就包括宫颈癌的全子宫切除手术。
利用腹腔镜进行宫颈癌手术时,由于形成气腹压的二氧化碳气流的流动,如果子宫颈癌的组织或癌细胞发生泄露,就容易造成癌细胞在腹腔内的播种,现有技术对这个问题没有有效的解决方法,因此临床上建议进行开腹手术,以避免癌细胞在随二氧化碳气流的流动而在腹腔内的播种。
因此,需要开发一种捆扎装置,在腹腔镜手术时,能轻松地递送入体内,在子宫与周围的组织和韧带分离后,能在离子宫颈安全的阴道部位,进行捆扎,完全封闭子宫颈前的阴道,从而完全避免癌细胞扩散,然后再切断阴道,将切除的病变子宫安全地取出体外。本发明的目的就在于设计一种能用于内窥镜手术中全宫切除时的子宫颈口的捆扎装置。
发明内容
本发明之内窥镜子宫颈口捆扎系统,捆扎带可以收拢在递送装置内,经手术通道递送入体内,释放捆扎带后,能对宫颈前安全部位的阴道进行有效捆扎,并完全封闭宫颈癌组织或液体流出的通道,从而避免癌细胞在随二氧化碳气流的流动而在腹腔内的播种,非常适合于内窥镜微创手术下的全子宫切除手术。
本发明之内窥镜子宫颈口捆扎系统,其特征在于:所述内窥镜子宫颈口捆扎系统900含捆扎装置100和递送装置200,所述捆扎装置100能收拢在所述递送装置200内;

C、所述递送装置200含递送鞘管21,所述捆扎装置100能收拢在所述递送鞘管21内。
所述捆扎装置100在使用时,能被收拢在所述递送鞘管21内,非常方便地经手术通道抵达手术区域,再将所述捆扎装置100推出所述递送鞘管21,即可释放所述捆扎装置100。然后将需要捆扎的组织放入所述捆扎孔13内,持续向远端拉动所述捆扎机构11,所述捆扎孔13会持续收拢,最终将组织捆扎紧,直至完全封闭,可以有效防止组织液溢出,防止癌细胞播种。
进一步,所述捆扎机构11是捆扎带1-1。所述捆扎机构11优选的是具有一定表面积的捆扎带1-1,可以更好地保证捆扎过程的牢固性,而又不会轻易将要捆扎的组织切割断裂。当然,本领域的技术人员也可以将所述捆扎机构11设计成链条状结构、珠链状结构等各种其它的结构的捆扎机构,都并不脱离本申请的保护范围。
所述捆扎带1-1采用柔软的弹性医用材料制成。采用柔软的弹性材料制造所述捆扎带1-1在保证捆扎牢固性的同时,可以更好地贴合组织,进一步保证腔道封闭的可靠性。
所述定位凹槽11-1是可以连续调节的连续定位凹槽11-11。所述定位凹槽11是连续定位凹槽11-1,这样在收拢所述捆扎孔13的过程中,可以根据组织大小以及需要捆扎紧张的程度,固定在任何位置。
所述定位凹槽11-1是单向运动凹槽11-12。单向运动的设计,可以保证在临床使用过程中所述捆扎机构11只能向一个方向运动,不会反向运动造成组织捆扎过程意外松脱。
所述递送装置200还含有推送机构22,所述推送机构22能将收拢在所述递送鞘管21内的所述捆扎装置100推出。所述推送机构22可以是连接在所述固定机构12上的联动推送机构201,也可以是单独设计,能通过所述递送鞘管21将所述捆扎装置100推出的独立推送机构202。
所述推送机构22含通孔22-1;所述捆扎装置100的捆扎机构11的远端102穿过所述通孔22-1后暴露在所述递送装置200外部。所述捆扎机构11的远端102暴露在所述递送装置200的外部,在临床使用过程中,医生可以直接在体外对所述捆扎装置100的捆扎孔13进行收拢,操作过程更加方便。

所述捆扎机构11上设有防滑机构11-3。本发明之捆扎装置,当对组织捆扎完成后,临床使用中,需要在被捆扎的组织附近进行各种手术操作,在整个临床手术过程中,所述捆扎机构11不能从组织上松弛、脱落,因此,本发明之内窥镜子宫颈口捆扎系统在所述捆扎机构11上设有防滑机构11-3,其核心目的就在于防止手术过程中所述捆扎机构11从被捆扎的组织上松弛、滑脱。
所述防滑机构11-3是设置在所述捆扎机构11上的防滑纹11-31、或防滑凸阶11-32。申请人在此只列举了上述2种具体防滑结构,实际应用中,本领域的技术人员可以根据需要设计出不同的防滑结构,但都不脱离本申请的保护范围。
所述防滑纹11-31沿所述捆扎带1-1的纵向分布。因所述捆扎带1-1上的连续定位凹槽11-1具有防止横向滑脱的作用,因此,所述防滑机构11-3的重要作用是防止所述捆扎机构11沿组织轴向滑脱,因此,所述防滑纹11-31通常沿所述捆扎带1-1的纵向分布。
所述捆扎机构11设有张开装置11-4。因在递送过程中,所述捆扎装置100是收拢在所述递送鞘管21内,由于所述递送鞘管21对所述捆扎装置100的约束作用,因此,当所述捆扎装置100从所述递送鞘管21中被释放后,所述捆扎机构11会因为挤压变形而造成所述捆扎孔13不易恢复,因此,设计的所述张开装置11-4可以在所述捆扎装置100从所述递送鞘管21中释放后将所述捆扎机构11张开,恢复所述捆扎孔13的形状。
所述张开装置11-3是弹性张开装置11-41。所述弹性张开装置11-41可以对所述捆扎机构11自动施加弹性张开力,临床使用过程中,当所述捆扎装置100从所述递送鞘管21中释放后,所述弹性张开装置11-41自动对所述捆扎机构11施加弹性张开力,使得所述捆扎机构11自动张开,恢复所述捆扎孔13的形状,临床使用过程更加方便。
所述推送机构22的远端设有限位装置22-2;所述固定机构12通过捆扎线121连接在所述限位装置22-2上。所述固定机构12连接在所述推送机构22上,这样所述推送机构22可以带动所述捆扎装置100在所述递送鞘管21内来回运动。同时,在所述推送机构22的远端设有限位装置22-2,将所述固定机构12通过所述捆扎线121连接在所述限位装置22-2上,由于所述捆扎装置100和所述推动机构22之间不产生相对运动,因此可以防止所述捆扎装置100向所述递送鞘管内收拢的过程中意外造成所述捆扎机构11的收拢运动。
所述推送机构22的近端设有推拉手柄22-3。所述推送机构22的近端设有的推拉手柄22-3可以方便推拉所述推送机构22在所述递送鞘管21内往复运动。
所述递送鞘管21的近端设有握持部21-1。临床使用过程中,医护人员可以方便地握在所述握持部21-1上,不容易在推拉的过程中滑脱,使用更方便、安全。
所述推送机构22还含锁定机构22-5;所述锁定机构22-5在锁定状态时,所述捆扎装 置100被固定在所述递送鞘管21内,不会从所述递送鞘管21内脱出。因为所述锁定机构22-5能将所述捆扎装置100固定在所述递送鞘管21内,因此,在运输途中以及临床使用的递送过程中,所述捆扎装置100不会意外从所述递送鞘管21中脱出,从而保证所述捆扎装置100不受污染,保证运输和使用过程的安全性。
所述锁定机构22-5的锁定方式是凹凸卡配合锁定方式、或旋转锁定方式、或过盈配合锁定方式。申请人在此只列举了上述三种具体的锁定方式,实际应用中,本领域的技术人员可以根据需要设计出不同的锁定方式,都不脱离本申请的保护范围。
所述推送机构22还含收拢机构22-6;所述收拢机构22-6可以在所述捆扎装置100将组织套扎后,将所述捆扎装置100收紧,并将剪断后的捆扎机构11的剩余部分通过所述推送机构22带出体外。所述收拢机构22-6通常设置在所述递送鞘管21或所述推送杆22-4的远端,所述收拢机构22-6可以与所述捆扎机构11形成固定连接,随着所述收拢机构22-6的回收运动,所述捆扎机构11随之运动,从而将所述捆扎孔13收紧,对组织形成捆扎。所述捆扎孔13收紧后,将所述捆扎机构11剪断,即可将被剪断的所述捆扎机构11随所述推送机构22带出体外,临床使用非常方便。
所述内窥镜子宫颈口捆扎系统900采用医用材料制造。因本发明之内窥镜子宫颈口捆扎系统需要进入人体进行使用,因此,与人体接触的部位都需要采用医用材料制造,以保证临床使用时的生物相容性要求。
临床使用时,将子宫500周围组织和韧带以及阴道旁组织分离切断后,然后用所述捆扎装置100将阴道上段套扎,以防止宫颈及受累阴道壁癌细胞5-1进入腹腔,之后再切断阴道,取出标本。
以带所述推送机构22的本发明之内窥镜子宫颈口捆扎系统为例,具体操作时,先将子宫周围的组织和韧带分离切断之后,游离子宫,将所述捆扎装置100收拢在所述递送鞘管21内,所述递送鞘管21通过穿刺器鞘管等手术通道到达手术部位,推动所述推送机构22将所述捆扎装置100从所述递送鞘管21内释放,然后通过所述捆扎孔13将所述捆扎装置100套在宫颈口外侧的阴道,向后拉所述拉环11-2,拉动所述捆扎机构11运动,收拢所述捆扎孔13,直至宫颈口外侧的阴道组织一起扎紧、完全封闭,然后用超声刀切断阴道600,将宫颈口已经捆扎封闭的子宫500,经阴道取出体外;或者是将宫颈口已经捆扎封闭的子宫500放置在内镜取物带内,经阴道600取出体外。
本发明之内窥镜子宫颈口捆扎系统含捆扎装置100和递送装置200。所述捆扎装置100含捆扎机构11、固定机构12及捆扎孔13。单向运动的设计,可以保证在临床使用过程中所述捆扎机构11只能向一个方向运动,不会反向运动造成组织捆扎过程意外松脱。所述递 送装置含递送鞘管21,所述捆扎装置100可收拢在所述递送鞘管21内,经穿刺器鞘管等手术通道到达手术部位后通过所述推送机构22可以将所述捆扎装置100从所述递送鞘管21内释放,将需要捆扎的组织放入所述捆扎孔13内,持续向远端拉动所述捆扎机构11,所述捆扎孔13会持续收拢,最终将组织扎紧、封闭,可以有效防止组织取出过程中组织液的溢出,避免肿瘤细胞的播种,使得手术过程更加安全。递送鞘管的设计,尤其适合于内窥镜手术下使用。
