Description

一种腔镜吻合器
技术领域
本发明涉及医疗器械领域，尤其涉及一种腔镜吻合器。
背景技术
目前微创手术占据了外科手术中的重要地位，其中，将病灶进行切除是外科手术的重要的一个组成部分，目前所通用的方法是外科的手术器械具有一个长的轴或杆状结构，在内窥镜的配合之下将轴或杆探入病灶，并将病灶切除。
腔镜吻合器作为手术器械的一种，是医学上使用的替代手工缝合的设备；吻合器的工作原理是将吻合器夹持在病灶部位，进行切除，切除的同时将病灶利用钛钉对组织进行离断或吻合，类似于订书机。
目前市场上腔镜吻合器采用斜楔结构出钉，详细的讲是通过推钉滑块按直线方向运动的同时，通过其斜楔结构将推钉片顶出，而推钉滑块均为塑胶件，在推进时的效果不理想。
发明内容
发明目的：针对现有技术的不足与缺陷，本发明提供一种击发力小、不易磨损、无油自润滑的腔镜吻合器。
技术方案：本发明的一种腔镜吻合器，其特征在于：包括吻合钉、钉仓、推钉滑块与推钉片；所述的钉仓设有若干个吻合钉，钉仓、推钉滑块与推钉片依次连接；所述的推钉片位于吻合钉之间；所述的推钉滑块外部设有有镍特氟龙层。
其中，所述的推钉滑块由05Cr17Ni4Cu4Nb不锈钢通过粉末冶金注射成型法制成。
其中，所述的推钉滑块在表面镀镍特氟龙层。
其中，所述的推钉滑块通过镍特氟龙层与钉仓刀槽壁连接。
其中，所述的推钉滑块通过镍特氟龙层与斜楔顶出的推钉片表壁连接。
有益效果：与现有技术相比，本发明具有以下显著优点：本发明的推钉滑块为无油自润滑推钉滑块，相比现有产品击发力更小，且不易磨损；推钉滑块使用05Cr17Ni4Cu4Nb材料，采用粉末冶金注射成型，需要在表面镀镍特氟龙，不管是与钉仓刀槽壁还是斜楔顶出的推钉片表壁，此镀层都起到自润滑作用，相比现有产品击发力可以减小1/3。此推钉滑块硬度有了很大的提升，击发过程中可以接近无磨损，解决了滑块降低带来的吻合钉高度不足的风险；击发力有了明显改善，此工艺可以突破此类产品的击发力瓶颈。
附图说明
图1为本发明的结构示意图；
图中1为吻合钉、2为钉仓、3为推钉滑块、4为推钉片。
具体实施方式
下面结合附图及具体实施方式对本发明的技术方案做进一步的描述。
本发明的一种腔镜吻合器，包括吻合钉1、钉仓2、推钉滑块3与推钉片4；钉仓2设有若干个吻合钉1，钉仓2、推钉滑块3与推钉片4依次连接；推钉片4位于吻合钉1之间；推钉滑块3外部设有有镍特氟龙层。推钉滑块3由05Cr17Ni4Cu4Nb不锈钢通过粉末冶金注射成型法制成。推钉滑块3在表面镀镍特氟龙层。推钉滑块3通过镍特氟龙层与钉仓2刀槽壁，及与斜楔顶出的推钉片4表壁连接连接。
目前市场上腔镜吻合器采用斜楔结构出钉，详细的讲是通过推钉滑块3按直线方向运动的同时，通过其斜楔结构将推钉片4顶出，而推钉滑块3均为塑胶件，在这种情况下就容易出现以下问题：1、塑胶件由于其硬度相比金属件偏低，在运动过程中容易出现磨损，这就会导致后排出钉高度不足，吻合口不耐压，出现组织渗血；2、由于钉仓2结构的特殊性，在运动过程中与之产生摩擦的配合面很难进行润滑，而一般塑胶件也难以实现自润滑，这就导致了整个击发过程中击发力偏大，严重时会出现组件切割到一半打不动，不得进行撤回。
本发明的推钉滑块3为无油自润滑推钉滑块3，相比现有产品击发力更小，且不易磨损；推钉滑块3使用05Cr17Ni4Cu4Nb材料，采用粉末冶金注射成型，需要在表面镀镍特氟龙，不管是与钉仓2刀槽壁还是斜楔顶出的推钉片4表壁，此镀层都起到自润滑作用，相比现有产品击发力可以减小1/3。此推钉滑块3硬度有了很大的提升，击发过程中可以接近无磨损，解决了滑块降低带来的吻合钉1高度不足的风险；击发力有了明显改善，此工艺可以突破此类产品的击发力瓶颈。
