附图说明Description of drawings
下面结合附图和实施例对本实用新型作进一步描述。Below in conjunction with accompanying drawing and embodiment the utility model is described further.
图1为本实用新型的结构示意图。Fig. 1 is the structural representation of the utility model.
具体实施方式detailed description
以下将结合附图对本实用新型进行详细说明，如图1所示：一种腹腔镜手术免气腹拉钩，包括两根基臂1，所述两根基臂的尾端铰接，两根基臂之间设置有调节螺钉2，基臂的头端设置有通孔，所述通孔处设置有转轴3，所述转轴的底端周向设置有多根支撑杆4，转轴的顶端设置有齿轮5，基臂上还设置有钳臂6和弧形槽7，所述钳臂通过与弧形槽滑动连接的销轴8与基臂连接，钳臂头端设置有与齿轮啮合的齿块9，钳臂与弧形槽之间通过锁紧螺钉10进行连接锁定。使用时，首先通过定位结构将该拉钩定位在合适位置，随后利用支撑杆将患者腹腔撑开合适空间，方便进行腹腔镜手术。该结构的拉钩，结构简单，使用方便；同时，通过转动调节螺杆，可调节两根基臂的张开程度，转动钳臂，通过齿块齿轮啮合带动转轴转动，可改变支撑杆在水平方向的张开程度，即调节对腹腔的撑开空间，待支撑杆的张开程度调整好后，拧紧锁紧螺钉，避免钳臂自由转动，实现对支撑杆位置的定位即可。The utility model will be described in detail below in conjunction with the accompanying drawings, as shown in Figure 1: a laparoscopic surgery free pneumoperitoneum retractor, comprising two base arms 1, the tail ends of the two base arms are hinged, and a Adjusting screw 2 is arranged, and the head end of base arm is provided with through hole, and described through hole is provided with rotating shaft 3, and the bottom end of described rotating shaft is provided with a plurality of supporting rods 4 circumferentially, and the top end of rotating shaft is provided with gear 5, and the base The arm is also provided with a pincer arm 6 and an arc groove 7, and the pincer arm is connected with the base arm through a pin shaft 8 slidingly connected with the arc groove. The locking screw 10 is used to lock the connection with the arc groove. When in use, the retractor is firstly positioned at a proper position through the positioning structure, and then the patient's abdominal cavity is stretched to a suitable space by using the support rod, so as to facilitate laparoscopic surgery. The pull hook of this structure is simple in structure and easy to use; at the same time, by turning the adjusting screw, the opening degree of the two base arms can be adjusted, and the opening degree of the two base arms can be adjusted by turning the pliers arm, and the rotating shaft is driven by the tooth block gear meshing, which can change the tension of the support rod in the horizontal direction. The opening degree is to adjust the opening space for the abdominal cavity. After the opening degree of the support rod is adjusted, tighten the locking screw to prevent the free rotation of the forceps arm and realize the positioning of the support rod.
作为上述技术方案的进一步改进，所述支撑杆上套设有橡胶套11。在使用过程中，橡胶套与患者腹腔接触，能提高手术过程的舒适度。As a further improvement of the above technical solution, a rubber sleeve 11 is sheathed on the support rod. During use, the rubber sleeve is in contact with the patient's abdominal cavity, which can improve the comfort of the surgical procedure.
