[0002] The minimally invasive resection technique for mediastinal tumors via the xiphoid approach is becoming increasingly mature. However, due to the narrow space in the anterior and posterior mediastinum behind the sternum, the operating space is small, and the surgery is quite difficult. It is necessary to elevate the sternum to expand the mediastinal space, expose the mediastinum, increase the operating space, reduce the difficulty of the surgery, and increase the safety of the surgery.

[0003] Chinese Patent Publication No. CN209059299U, published on July 5, 2019, discloses a simple sternal retractor device for cardiac surgery, comprising a top plate, a vertical plate, a connecting plate, a suction cup, an electric push rod, a horizontal plate, a T-shaped slider, a hook, a lighting lamp, a power supply, an L-shaped connecting rod, a fixing frame, a Fresnel lens, a mounting base, a waste container, and a mounting block. Vertical plates are fixedly mounted on the left and right sides of the bottom of the top plate, and a connecting plate is mounted on the bottom of the vertical plate. A suction cup is mounted on the bottom of the connecting plate, and an exhaust pipe is mounted on one side of the suction cup. An electric push rod is vertically mounted in the middle of the bottom of the top plate. The bottom of the electric push rod is connected to a horizontal plate with several limiting holes extending horizontally through its front and rear ends. The bottom of the horizontal plate is slidably connected to... The system includes a T-shaped slider with limit holes through its front and rear ends. The bottom of the T-shaped slider is connected to a hook via a spring. A connecting seat is located in the middle of the bottom of the horizontal plate, and a gooseneck tube is installed inside the connecting seat. A power supply is fixed to the upper end of the horizontal plate, and a light is connected to the bottom of the gooseneck tube. The power supply and the light are electrically connected. A mounting rod is vertically installed in the middle of the front end of the horizontal plate. The mounting rod is threaded to an L-shaped connecting rod, and a fixing frame is threaded to the bottom of the L-shaped connecting rod. Fresnel lenses are slidably connected to the left and right sides of the fixing frame. A mounting seat is fixed to the rear end of the vertical plate on the right side, and a waste container is slidably connected to the mounting seat. A mounting block with mounting holes through its front and rear ends is fixed to the right end of the vertical plate on the right side. The shortcomings of the above-mentioned patent are as follows: the sternal hook device uses a suction cup to connect and fix the entire device. Since the suction cup's adsorption capacity is easily affected by external environmental factors such as temperature and humidity, its adsorption capacity is not stable. Moreover, the suction cup has limited load-bearing capacity and is only suitable for fixing lightweight items. It is difficult to stably adsorb heavy frame-type objects such as the sternal hook device, resulting in low installation stability and a high risk of tipping over.

[0004] In summary, there is a need for a clamping assembly for fixing the balance hook device that can improve the installation stability of the hook device. Utility Model Content
