具体实施方式detailed description
下面结合附图和具体实施方式对本实用新型进行详细说明。The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
本实用新型提供了一种人体组织腔隙自适性可弯曲式穿刺器，参见图1，包括中空的转接头3，该转接头3底部连接有可弯曲的外套管1，该转接头3与外套管1用于供穿刺杆穿过。The utility model provides a self-adaptive bendable puncture device for human tissue cavity, as shown in Fig. 1, which includes a hollow adapter 3, the bottom of which is connected with a bendable outer tube 1, and the adapter 3 is connected with the The outer sleeve 1 is used for passing the puncture rod.
通常可以将外套管1设置为外壁光滑不锈钢软管，例如外部设有光滑塑料管壁的螺纹管结构，这样可以保证外套管1外壁的光滑，避免对人体内组织造成损伤，同时使得外套管1具有有一定的弹性和刚性，便于手术操作。Usually, the outer casing 1 can be set as a stainless steel hose with a smooth outer wall, such as a threaded pipe structure with a smooth plastic pipe wall on the outside, so that the outer wall of the outer casing 1 can be guaranteed to be smooth, avoiding damage to the internal tissues of the human body, and at the same time make the outer casing 1 It has certain elasticity and rigidity, which is convenient for operation.
参见图2c，本实用新型将外套管1设置为可以弯曲，并能根据穿入其中 的手术器械的外形发生适应性形变的软管，这样一来，就使得该穿刺器，不仅仅可以供直线型手术器械顺利穿过，还同样适用于弯头手术钳的穿过，使得该穿刺器的适用范围更广，操作更加方便。Referring to Fig. 2c, the utility model sets the overtube 1 as a flexible tube that can be bent and adaptively deformed according to the shape of the surgical instrument inserted therein. The smooth passage of the type surgical instrument is also suitable for the passage of the curved surgical forceps, so that the trocar has a wider application range and is more convenient to operate.
同时，在外套管1上设置有充气阀门2，可以向外套管1内充气，可以增加人体体腔内空间大小，利于手术操作。At the same time, an inflation valve 2 is provided on the outer sleeve 1, which can inflate the outer sleeve 1, and can increase the size of the space in the body cavity of the human body, which is beneficial to the operation.
外套管1内靠近该转接头3的一端设置有具有回缩功能的单向薄膜单元4，薄膜单元4包括倒锥形薄膜，薄膜的底端敞开并朝向所述转接头3，薄膜的顶端上开有缝隙。常态下，薄膜上的缝隙处于闭合状态，保证外套管1内的气体不会进入转接头3内；而在使用穿刺杆时，可以将穿刺杆撑开缝隙，并从缝隙中穿过进入外套管1内；当取出穿刺杆后，该缝隙会自然闭合。One end of the outer sleeve 1 close to the adapter 3 is provided with a retractable one-way film unit 4, the film unit 4 includes an inverted tapered film, the bottom end of the film is open and faces the adapter 3, and the top end of the film is There is a gap. Under normal conditions, the gap on the film is closed to ensure that the gas in the outer sleeve 1 will not enter the adapter 3; when using the puncture rod, the puncture rod can be stretched to open the gap and pass through the gap into the outer sleeve 1; when the puncture rod is taken out, the gap will be closed naturally.
该转接头3的直径与外套管1的直径比为(1.2-1.8)：1，这样的设置使得手术中，同时使用两个穿刺器时，两两转接头3在之间不会产生干涉，使用更加方便灵活。The ratio of the diameter of the adapter 3 to the diameter of the outer cannula 1 is (1.2-1.8): 1. This setting makes it possible for two adapters 3 to not interfere with each other when two trocars are used at the same time during the operation. It is more convenient and flexible to use.
图2a-图2c表示本实用新型人体组织腔隙自适性可弯曲式穿刺器穿入组织弯曲抓钳的分步骤的状态示意图。具体参见图2a，使用组织弯曲抓钳5穿过本实用新型的人体组织腔隙自适性可弯曲式穿刺器时，首先将组织弯曲抓钳5的前段伸入外套管1；参见图2b，在继续伸入的过程中，组织弯曲抓钳5的弯曲段就进入外套管1，由于外套管1为软管，则外套管1也随之弯曲以适应组织弯曲抓钳5的弯曲段的形状；参见图2c，待适应组织弯曲抓钳5的弯曲段完全穿出外套管1后，该外套管1套在组织弯曲抓钳5后段上，同时外套管1恢复直线状态。经过上述的过程说明本实用新型的人体组织腔隙自适性可弯曲式穿刺器，不仅可以适应直线型手术器械，还可以很好地适应有弧度的弯曲手术器械的使用。Fig. 2a-Fig. 2c show the step-by-step state diagrams of the self-adaptive bendable puncture device in the human tissue cavity of the present invention penetrating into the tissue bending grasper. Referring specifically to Fig. 2a, when using the tissue bending grasper 5 to pass through the self-adaptive bendable puncturer of the human tissue cavity of the present utility model, firstly, the front section of the tissue bending grasper 5 is inserted into the outer sleeve 1; see Fig. 2b, In the process of continuing to extend in, the curved section of the tissue bending grasper 5 just enters the outer sleeve 1, and since the outer sleeve 1 is a flexible pipe, the outer sleeve 1 also bends thereupon to adapt to the shape of the bending section of the tissue bending grasper 5 ; See Figure 2c, after the curved section of the adapted tissue bending grasper 5 passes through the outer sleeve 1 completely, the outer sleeve 1 is set on the rear section of the tissue bending grasper 5, and the outer sleeve 1 returns to a straight line. The above-mentioned process shows that the self-adaptive bendable puncture device for human tissue cavity of the present invention can not only adapt to straight surgical instruments, but also can well adapt to the use of curved surgical instruments with radians.
