技术领域technical field
本发明涉及一种腹腔镜外科手术器械，特别是涉及在腹腔镜手术中使用的组合式密封组件及使用了这种密封组件的穿刺器。The invention relates to a laparoscopic surgical instrument, in particular to a combined sealing component used in laparoscopic surgery and a trocar using the sealing component.
背景技术Background technique
腹腔镜手术得到了越来越广泛的应用，为了避免医源性感染，腹腔镜手术中使用的一次性穿刺器(Trocar)的用量也越来越大，在保证使用性能的基础上，简化结构，方便使用，提高性能，这一趋势已成为穿刺器改进的方向。Laparoscopic surgery has been more and more widely used. In order to avoid iatrogenic infection, the amount of disposable trocar (Trocar) used in laparoscopic surgery is also increasing. On the basis of ensuring the performance, the structure is simplified , easy to use, and improved performance, this trend has become the direction of trocar improvement.
现有技术的穿刺器在手术器械左右晃动时，由于密封件受力不均，容易在端密封件与单向阀密封件之间造成漏气，因此需要对现有技术进行改进。When the trocar in the prior art shakes the surgical instrument from side to side, air leakage is likely to occur between the end seal and the one-way valve seal due to uneven force on the seal. Therefore, the prior art needs to be improved.
发明内容Contents of the invention
组合式密封组件，所述组合式密封组件9含端密封件1及单向阀2。其特征在于：A combined sealing assembly, the combined sealing assembly 9 includes an end seal 1 and a one-way valve 2 . It is characterized by:
A.所述端密封件1含手术器械孔10、端密封机构11、壳体12及连接翼13；所述端密封机构11安装在壳体12内，所述连接翼13设在壳体12的下端12-1上；所述连接翼13上设有连接孔13-1和定位筋13-2；A. The end seal 1 includes a surgical instrument hole 10, an end seal mechanism 11, a housing 12 and a connecting wing 13; the end sealing mechanism 11 is installed in the housing 12, and the connecting wing 13 is arranged on the housing 12 On the lower end 12-1; the connecting wing 13 is provided with a connecting hole 13-1 and a positioning rib 13-2;
B.所述单向阀2含手术器械孔20、单向阀密封机构21、壳体22、连接钩23及定位槽24；所述单向阀密封机构21安装在壳体22内；所述连接钩23和定位槽24设在所述壳体22外侧上；B. The one-way valve 2 contains a surgical instrument hole 20, a one-way valve sealing mechanism 21, a housing 22, a connecting hook 23 and a positioning groove 24; the one-way valve sealing mechanism 21 is installed in the housing 22; The connecting hook 23 and the positioning groove 24 are arranged on the outer side of the housing 22;
C.所述连接钩23能镶嵌在所述连接翼13的连接孔13-1内，所述定位筋13-2与定位槽24形成凹凸配合定位；C. The connecting hook 23 can be embedded in the connecting hole 13-1 of the connecting wing 13, and the positioning rib 13-2 and the positioning groove 24 form a concave-convex matching positioning;
D.所述端密封件1的手术器械孔10的中心线与所述单向阀2的手术器械孔20的中心线重合或基本重合。D. The centerline of the surgical instrument hole 10 of the end seal 1 coincides or substantially coincides with the centerline of the surgical instrument hole 20 of the one-way valve 2 .
进一步，所述定位筋13-2为曲线。所述定位槽24为曲线型凹槽。所述曲线型定位筋13-2与曲线型凹槽的所述定位槽24之间能形成凹凸配合。当穿过所述穿刺器100的手术器械200发生左右晃动时，由于所述定位筋13-2与所述定位槽24之间形成的凹凸配合具有定位作用，限制了所述端密封件1与所述单向阀2之间的摆动间隙，因此，所述组合式密封组件9的端密封件1和单向阀2之间不会发生相对移动，可以很好地防止漏气，保持良好的密封性能。Further, the positioning rib 13-2 is a curved line. The positioning groove 24 is a curved groove. A concave-convex fit can be formed between the curved positioning rib 13-2 and the positioning groove 24 of the curved groove. When the surgical instrument 200 passing through the trocar 100 shakes left and right, because the concave-convex cooperation formed between the positioning rib 13-2 and the positioning groove 24 has a positioning effect, the contact between the end seal 1 and the positioning groove 24 is limited. The swing gap between the one-way valves 2, therefore, there will be no relative movement between the end seal 1 of the combined sealing assembly 9 and the one-way valve 2, which can well prevent air leakage and maintain a good Sealing performance.
所述定位筋13-2为直线。所述定位槽24为直线型凹槽。所述直线型定位筋13-2与直线型凹槽的所述定位槽24之间能形成凹凸配合。与曲线型的设计相比，直线型的所述定位筋13-2与所述定位槽24的设计，可以更好地保证所述端密封件1和单向阀2之间不会发生相对移动，密封性能更好。而且，直线型的设计，所述定位筋13-2滑入所述定位槽24时阻力更小，安装更方便。The positioning ribs 13-2 are straight lines. The positioning groove 24 is a linear groove. A concave-convex fit can be formed between the linear positioning rib 13-2 and the positioning groove 24 of the linear groove. Compared with the curved design, the linear design of the positioning rib 13-2 and the positioning groove 24 can better ensure that there will be no relative movement between the end seal 1 and the one-way valve 2 , better sealing performance. Moreover, with the linear design, the positioning rib 13-2 has less resistance when sliding into the positioning groove 24, and the installation is more convenient.
穿刺器，其特征在于所述穿刺器100含权利要求1所述组合式密封组件9。The trocar is characterized in that the trocar 100 includes the combined sealing assembly 9 of claim 1.
本发明之组合式密封组件9，含端密封件1及单向阀2，所述密封组件1和单向阀2之间通过所述连接翼13上的连接孔13-1与所述单向阀2上的连接钩23形成凹凸卡配合连接。所述定位槽24不仅具有导向作用，方便所述连接钩23滑入所述连接翼13的连接孔13-1内，实现凹凸卡配合连接；而且，所述端密封件1上的定位筋13-2与所述单向阀2上的定位槽24形成凹凸配合定位，可以防止器械200晃动造成的漏气。使用了本发明之组合式密封组件9的穿刺器100，具有组装便利，拆卸简单，连接牢固、密封性好的特点。The combined sealing assembly 9 of the present invention includes an end seal 1 and a one-way valve 2, and the connection hole 13-1 on the connecting wing 13 is connected to the one-way valve 2 between the sealing assembly 1 and the one-way valve 2. The connecting hook 23 on the valve 2 forms a concave-convex snap-fit connection. The positioning groove 24 not only has a guiding function, but also facilitates the sliding of the connecting hook 23 into the connecting hole 13-1 of the connecting wing 13 to realize the concave-convex snap-fit connection; moreover, the positioning rib 13 on the end seal 1 -2 and the positioning groove 24 on the one-way valve 2 form concave-convex cooperation positioning, which can prevent air leakage caused by the shaking of the instrument 200. The trocar 100 using the combined sealing assembly 9 of the present invention has the characteristics of convenient assembly, simple disassembly, firm connection and good sealing performance.
