The structure of the part is the same as that of the existing energy knife, which is not the invention point of the invention and is not described in detail.
In this embodiment, the monopolar electrical hook assembly 200 includes: two single-pole electric hook push-pull buttons 210, a single-pole electric hook push-pull piece 220, a single-pole electric hook 230, a single-pole electric hook insulating sheath 240, a single-pole electric hook closing button 250, a single-pole electric hook cutting button 260 and a single-pole electric hook conductive metal elastic sheet 270.
The unipolar electric hook 230 is formed as an integral metal member by a metal ring 231, a hook body 232, and a hook head 233. The tail part of the hook body 232 is positioned on the end surface of the metal ring 231, and the hook head 233 is positioned at the head part of the hook body 232; the metal ring 231 is located within the housing 310.
The main portion of the monopolar electrical hook 230 has a hook body 232 and a hook head 233 on one side of the energy blade 110. The metal ring 231 is sleeved on the energy knife body 110, the monopole electric hook insulating sheath 240 is sleeved outside the energy knife body 110 and the hook body 232, and the monopole electric hook insulating sheath 240 is fixedly connected with the monopole electric hook 230 and moves synchronously. Certainly, an insulating sleeve can be arranged between the energy knife body 110 and the hook body 232 to ensure the performance between the two.

In this embodiment, the single-pole electric hook conductive metal dome 270 is disposed on the housing 310 at a position where the housing 310 and the rotation knob 320 are combined. The monopole electrical hook conductive metal dome 270 is electrically connected to the power cord via a cable. When the monopolar electric hook push-pull member 220 moves outwards in the housing 300, the monopolar electric hook 230 and the monopolar electric hook insulating sheath 240 are driven to move outwards the housing 300 until the monopolar electric hook insulating sheath 240 completely covers the energy cutter head 110; the single-pole electric hook conductive metal spring sheet 270 is in contact with the metal ring 231.
In this embodiment, the monopolar electric hook closing button 250 and the monopolar electric hook cutting button 260 are located on the housing body 310, below the slide slot 311, and are disposed adjacent to the slide slot 311. The monopolar electric hook push-pull button 210 covers the monopolar electric hook closing button 250 and the monopolar electric hook cutting button 260 when the monopolar electric hook assembly 200 is moved inward the housing 300.
When the monopolar electric hook works, when the monopolar electric hook cutting button 260 and the monopolar electric hook closing button 250 are pressed to start the high-frequency energy host connected with a power line, corresponding cutting and closing electric energy is input, the electric energy is transmitted to the electrode electric hook conductive metal elastic sheet 270 through a cable, then to the conductive metal ring 231 of the monopolar electric hook 230, to the hook body 232 and to the hook head 233 at the far end, and electric cutting and hemostasis are realized. The mechanism and function of this part are the same as those in the prior art, and are not described in detail.
The main function of the dual-function surgical instrument is the switching between two modes of an energy knife and a monopolar electric hook. When the monopolar electric hook needs to be used, the monopolar electric hook push-pull button 210 on any side is pushed to drive the monopolar electric hook push-pull piece 220 to move outwards in the shell 300, and the whole monopolar electric hook 230 and the monopolar electric hook insulating sheath 240 are driven to move outwards the shell 300 until the monopolar electric hook insulating sheath 240 completely wraps and covers the energy cutter head 110; the operating mode of the monopolar electric hook is now in place, as shown in fig. 4-6.
When the energy knife needs to be used, the unipolar electric hook push-pull button 210 is pulled inwards, the unipolar electric hook push-pull piece 220 moves inwards in the shell 300, and drives the unipolar electric hook 230 and the unipolar electric hook insulating sheath 240 to move inwards in the shell 300 until the length of the energy knife body 120 exposed out of the shell 300 exceeds the length of the unipolar electric hook 230 exposed out of the shell 300 and the length of the shell 300; in this case in the working mode of the energy knife, as shown in fig. 1 to 3.
