Tumor resection device is one of the medical devices.

[0003] Patent No. CN219021419U discloses a tumor resection device with a clamping structure, which connects and fixes the clamping component and the shearing component through a lifting structure. Therefore, when in use, the clamping component and the shearing component can be held by both hands to perform the clamping and shearing processes at the same time, so that a single person can complete all operations, reducing the occupation of the affected area space and making the operation more flexible. However, during use, when the clamping component fixes the tumor and the other hand operates the shearing component to remove it, the mind cannot be divided to control the force applied by the hand holding the clamping component, which may cause excessive force to damage the tumor or insufficient force to move the tumor, affecting the normal progress of the operation.

[0023] (III) Beneficial effects

[0024] The present application provides a tumor removal device. The beneficial effects are as follows:

[0025] 1. The tumor resection device is provided with a limit mechanism.

When the clamping mechanism moves, it drives the rack to move. The movement of the rack drives the gear to rotate. The rotation of the gear drives the rotating rod on one side of the connection frame to rotate. The rotation of the rotating rod drives the limit plate to rotate. After the clamping mechanism finishes moving, the connection plate is released. Driven by the elastic force of the spring itself, the telescopic rod is shortened and drives the limit rod on one side of the connection plate to insert into the limit hole, thereby completing the limit fixation of the clamping mechanism. This prevents the doctor from being unable to accurately control the force applied by holding the clamping mechanism during tumor resection, resulting in damage to the tumor or movement of the tumor, thereby ensuring a smooth tumor resection operation.

[0026] 2. The tumor resection device is provided with an adjustment mechanism. The rotating dial drives the screw threadedly connected to the adjustment hole to rotate. The rotation of the screw drives the resection mechanism rotatably connected to the screw to move to a position suitable for resection surgery, thereby increasing the adjustable distance between the clamping mechanism and the resection mechanism and expanding the use range of the tumor resection device.
