The knife head is installed at one end of the handle, the cable is installed at the other end of the handle, the circuit board is installed inside the handle, the button is installed on the handle, the button cooperates with the circuit board, the knife head is electrically connected to the circuit board, and the circuit board is electrically connected to the cable.
[0005] Further, the cable is connected to the high-frequency electric knife.
[0006] Further, the knife head includes a first knife head, a second knife head and a third knife head.
[0007] Further, the first knife head is a short knife head, the second knife head is a long knife head with a hook, and the third knife head is a short knife head with a hook.
[0008] Further, the number of the buttons is two, namely an electrocoagulation button and an electrocision button.
[0009] Further, a connection hole is provided on the handle, a connection sleeve is sleeved outside the knife head, and the connection sleeve is inserted into the connection hole.
[0010] Further, both the connection hole and the connection sleeve are arranged in a hexagonal structure.
[0011] Further, a Teflon is provided between the knife head and the connection sleeve.
[0012] Further, the connection sleeve is tightly fitted with the connection hole.
[0013] Compared with the prior art, the present utility model has the following advantages: The hand-controlled knife head replaceable electrocautery hook for single-port thoracoscopic surgery is hand-controlled. The electrocoagulation and electrocision can be controlled by the button on the handle. The advantage of the hand-controlled type is that the operation is more precise during the surgery and there is no sluggishness during electrocoagulation and electrocision. At the same time, the knife head of the hand-controlled knife head replaceable electrocautery hook for single-port thoracoscopic surgery can be replaced. For example, the No. 1 knife head can be replaced when cutting the skin, and the No. 2 knife head and No. 3 knife head can be replaced when separating and hemostasizing the lung tissue in single-port thoracoscopic surgery, while the handle does not need to be replaced. That is to say, in one operation, there is no need to replace the electrocautery hook, and only the knife head needs to be replaced to complete the operations of cutting the skin and separating and hemostasizing the lung tissue in single-port thoracoscopic surgery, which can reduce the cost of the operating room.
