本发明属于外壳手术医疗器械领域，具体涉及一种外科手术用可伸缩术中解剖器。The invention belongs to the field of medical equipment for shell surgery, and in particular relates to a retractable intraoperative dissector for surgery.
背景技术Background technique
外科手术用的解剖器即电刀笔，是进行手术组织切割的外科手术器械。电刀笔是通过高频电流穿过电极达到目标组织，目标组织与电极相靠近的部位被高频电流迅速加热气化，通过高频电流的变化实现切割、凝血的功能。目前在外科手术中，由于切割组织的深度不同，需要不同长度的电极，具体操作时，医生会用不同长度电极的电刀笔，切换麻烦，多个电刀笔造成资源的浪费；而且现有的电刀笔中电极更换不便，如电极分为电钩、电棒、电刀、电铲和电针，手术中使用多种电极时就需要多个电刀笔，使用非常不方便。The dissector used in surgery is an electric knife pen, which is a surgical instrument for cutting surgical tissues. The electric knife pen passes through the electrode through the high-frequency current to reach the target tissue, and the part close to the target tissue and the electrode is rapidly heated and vaporized by the high-frequency current, and the function of cutting and coagulation is realized through the change of the high-frequency current. At present, in surgical operations, electrodes of different lengths are required due to the different depths of tissue cuts. During specific operations, doctors will use electrosurgical pens with electrodes of different lengths, which is troublesome to switch, and multiple electrosurgical pens cause waste of resources; and the existing electrosurgical pens It is inconvenient to replace the electrodes in the knife pen. For example, the electrodes are divided into electric hook, electric rod, electric knife, electric shovel and electric needle. When multiple electrodes are used in the operation, multiple electric knife pens are needed, which is very inconvenient to use.

The connecting rod 121 is inserted into the slot 403 to contact the contact spring 11. The surface of the contact spring 11 is formed with an arc-shaped protrusion that is clamped with the connector. The arc-shaped protrusion can improve the stability of the connection between the contact spring 11 and the connector, and can clamp the electrode 12 tightly.
卡槽403的尾端设有橡胶垫14，用于为连接杆121限位。当电极12插入卡槽403中，由于力度不易控制，橡胶垫14的设置能够为连接杆121插入深度定位，并且防止连接杆121的损伤。A rubber pad 14 is provided at the end of the slot 403 for limiting the position of the connecting rod 121 . When the electrode 12 is inserted into the slot 403 , since the strength is difficult to control, the setting of the rubber pad 14 can position the insertion depth of the connecting rod 121 and prevent the connecting rod 121 from being damaged.
摩擦凸台108为硬质塑料，并该摩擦凸台通过螺钉可拆卸连接在壳体101的下表面。并该摩擦凸台为半圆弧形，其表面设有摩擦条纹。摩擦凸台方便医生在使用时对手指的支撑，并且防滑，使用更加稳定，同时内部提供空腔，用于安装吸气装置7。吸气装置7为吸气泵。The friction boss 108 is made of hard plastic, and the friction boss is detachably connected to the lower surface of the housing 101 by screws. And the friction boss is in the shape of a semicircle, and the surface is provided with friction stripes. The friction boss is convenient for the doctor to support the fingers during use, and is non-slip, making the use more stable. Meanwhile, a cavity is provided inside for installing the suction device 7 . The suction device 7 is a suction pump.
作为本案可选的实施例，摩擦凸台108为气囊，且排烟管6和抽烟管8上均设有单向阀。该结构在降低成本的状况下，通过外科医生按压气囊，由于排烟管6和抽烟管8均设有单向阀，气体不能回流，可以方便的将产生的烟吸收，使用方便。As an optional embodiment of this case, the friction boss 108 is an air bag, and both the smoke exhaust pipe 6 and the smoke exhaust pipe 8 are provided with one-way valves. With this structure, the surgeon presses the air bag under the condition of reducing the cost. Since the exhaust pipe 6 and the smoke pipe 8 are equipped with one-way valves, the gas cannot flow back, and the generated smoke can be easily absorbed, which is convenient to use.
作为优化设计，照明灯10设置在CCD图像采集器9的下方，且照明灯10设有多个，均为LED灯。CCD图像采集器9可以采集操作时电极12与目标组织作用的路径以及图像，方便分析处理。As an optimal design, the illuminating lamp 10 is arranged below the CCD image collector 9, and there are multiple illuminating lamps 10, all of which are LED lamps. The CCD image collector 9 can collect the path and image of the interaction between the electrode 12 and the target tissue during operation, which is convenient for analysis and processing.
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。The above is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Anyone skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present invention. Should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
