Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a surgical electric hook with an aspirator. Background Art

[0002] The electric hook is a commonly used instrument in thoracoscopic surgery, with a function similar to that of an electric knife. Its working principle is that the electric hook forms an electrical circuit with the patient's body and a negative electrode plate attached to the patient's skin, generating current in the electrode to cut tissue. Its shape is similar to a hook. In order to achieve both the electric hook and suction operations, a surgical electric hook with an aspirator is generally used. During use, the operator only needs to hold a set of equipment in hand to achieve both the electric hook and suction operations, thereby reducing the difficulty of operation. Since the tip of the electric hook is always exposed, it is easy to come into contact with the outside during transfer and placement, causing wear and even damage. Therefore, a surgical electric hook with an aspirator is proposed to protect the tip of the electric hook. Utility Model Content

A connecting line 11 is provided at the bottom end of the electric hook body 3, and the end of the connecting line 11 away from the electric hook body 3 passes through the blocking cover 8. A small section of the connecting line 11 is left in the shell 1 to prevent the connecting line 11 from being tightened when the protective cover 2 is disassembled, causing the protective cover 2 to be difficult to remove. A valve 9 is fixed to the bottom end of the blocking cover 8 by adhesive, and a hose 10 is fixed to the bottom end of the valve 9 by adhesive. A vent hole connected to the valve 9 is opened on the blocking cover 8, and the vent hole is connected to the interior of the shell 1.

[0024] During use, the connecting line 11 is used to electrically connect the electric hook body 3 to the external controller and the driving device, and the end of the hose 10 away from the valve 9 is connected to the suction end of the external suction device. The electric hook tip forms an electrical circuit with the patient's body and the negative electrode plate attached to the patient's skin, and current is generated in the electrode to perform tissue cutting (existing technology). The suction holes on both sides of the shell 1 are used to suck away the generated smoke or liquid, and the sucked smoke or liquid is discharged through the hose 10. The setting of the valve 9 is conducive to adjusting the air flow in the hose 10 as needed. After loosening the locking bolt 6, the protective cover 5 is pushed away from the valve 9. After the electric hook tip is located in the protective cover 5, the locking bolt 6 is tightened. The protective cover 5 can protect the electric hook tip.

[0027] In order to improve the sealing between the protective cover 2 and the housing 1, for example, Figure 3 As shown, a sealing gasket 12 is fixed to the protective cover 2 by adhesive.

[0028] For the convenience of holding the protective cover 2, exemplarily, as Figure 3 shown, a plurality of anti-slip protrusions 13 are integrally formed on the outer wall of the protective cover 2.

[0029] When the utility model is in use, the electric hook body 3 is electrically connected to an external controller and a driving device by using a connecting wire 11. One end of the hose 10 far away from the valve 9 is docked with the suction end of an external aspirator. The electric hook tip forms an electric circuit with the patient's body and the negative electrode plate attached to the patient's skin, and a current is generated in the electrode for tissue cutting (prior art). The generated smoke or liquid is sucked away through the suction holes on both sides of the housing 1, and the sucked smoke or liquid is led out through the hose 10. The setting of the valve 9 facilitates adjusting the air flow rate in the hose 10 as needed;

[0030] When the electric hook body 3 is not in use, after loosening the locking bolt 6, the protective cover 5 is pushed to move away from the valve 9. After the electric hook tip is located in the protective cover 5, the locking bolt 6 is tightened. The protective cover 5 can protect the electric hook tip. The convex block 4 cooperates with the sliding groove on the inner wall of the protective cover 5, which can prevent the protective cover 5 from rotating during the movement, resulting in the protective cover 5 blocking the suction holes. Even when the electric hook body 3 is not in use, the smoke or liquid can be sucked away through the suction holes.
