Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a bipolar electrocoagulation knife for minimally invasive surgery and a preparation method thereof. Background Art

[0002] Currently, during minimally invasive surgery, when excising the diseased tissue of a patient, a doctor uses scissors for cutting. However, after excision by the traditional cutting method, hemostasis cannot be immediately performed, and special instruments need to be additionally used for blood coagulation, which affects the surgical process.

[0003] In the prior art, the scissor clip is inserted into the human body. Under the vision of an endoscope, the scissor clip is aligned with the diseased tissue site to be cut. The plug is connected to a high-frequency power supply to make the scissor clip charged. The hand is put into the handle for cutting. The scissor blade cuts open the diseased tissue site. At the same time, the scissor clip with a high-frequency power supply makes bipolar contact with the cut diseased tissue to generate heat, and the tissue at the cut surface dehydrates and solidifies to achieve hemostasis. The scissor clip in a curved shape can trim the tissue edge during cutting. After cutting is completed, the high-frequency power supply is cut off, and the scissor clip is taken out of the human body.

[0004] However, in the aforementioned prior art, a doctor needs to manually apply force for the cutting operation, which increases the intensity of minimally invasive surgery. At the same time, if the doctor's hand shakes due to fatigue during high-intensity minimally invasive surgery, it is likely to affect the surgical quality and surgical safety. Summary of the Invention

[0005] The purpose of the present invention is to provide a bipolar electrocoagulation knife for minimally invasive surgery and a preparation method thereof, so as to solve the problems in the prior art that a doctor needs to manually apply force for the cutting operation, which increases the intensity of minimally invasive surgery, and at the same time, if the doctor's hand shakes due to fatigue during high-intensity minimally invasive surgery, it is likely to affect the surgical quality and surgical safety.

[0006] To achieve the above purpose, the present invention provides a bipolar electrocoagulation knife for minimally invasive surgery, including a scissor clip and a cutting and electrocoagulation assembly;

[0007] The cutting and electrocoagulation assembly includes a rotating shaft, a housing, a telescopic driving unit, two electric wires, a handle, and a battery pack. One end of the rotating shaft is fixedly connected to the housing and is located on the inner top wall of the housing.

[0009] Among them, the shearing and electrocoagulation assembly further includes a PLC controller, which is fixedly connected to the housing and is located on the inner top wall of the housing. The PLC controller is electrically connected to the intelligent display screen, the battery pack, and the telescopic driving unit respectively.

[0010] Among them, the telescopic driving unit includes two fixing blocks, an electric telescopic rod, and a switch. The two fixing blocks are both fixedly connected to the scissor clip and are respectively located at both ends of the scissor clip. The two ends of the electric telescopic rod are respectively fixedly connected to the corresponding fixing blocks. The switch is fixedly connected to the handle and is located at one end of the handle away from the housing.

[0011] Among them, the bipolar electrocoagulation knife for minimally invasive surgery further includes a grip enhancement assembly, which is arranged on the housing.

[0012] Among them, the grip enhancement assembly includes two protective rod bodies and an anti-slip rubber sleeve. The two protective rod bodies are both fixedly connected to the housing and are symmetrically distributed on both sides of the housing. The anti-slip rubber sleeve is fixedly connected to the handle and is sleeved on the outer wall of the handle.

[0013] Among them, the grip enhancement assembly further includes two LED lights, and the two LED lights are both fixedly connected to the corresponding protective rod bodies and are respectively located on one side of the corresponding protective rod bodies.

[0014] The present invention also provides a preparation method for a bipolar electrocoagulation knife for minimally invasive surgery. Using the above-mentioned bipolar electrocoagulation knife for minimally invasive surgery, the method includes the following steps:

[0015] Use a die-casting mold to make the scissor clip, and then install it on the rotating shaft;

[0016] Connect the two ends of the wire to the scissor clip and the battery pack respectively, so that the scissor clip can be powered on, and the two shearing ends of the scissor clip can form a bipolar knife head. When removing the lesion, heat is generated, and the cut surface is prevented from dehydrating and solidifying;

[0017] Weld the die-cast fixing blocks on the scissor clip, and at the same time fix the electric telescopic rod as the power source;

[0018] Then fixedly install the PLC controller and the intelligent display screen in sequence;

[0019] Use a bending machine to bend the metal raw material to make the protective rod body;

[0021] Finally, install and fix the anti-slip rubber sleeve and the switch, and then it can be used.

[0022] For a bipolar electrocoagulation knife for minimally invasive surgery and its preparation method according to the present invention, a doctor holds the handle, aligns the scissor clamp with the lesion, operates through the telescopic drive unit to drive the scissor clamp to perform a shearing operation, the two shearing ends of the scissor clamp rotate around the rotating shaft, and at the same time after the electric wire is connected to the battery pack, a high-frequency power supply is transmitted to the scissor clamp to generate heat, heating the shearing part to make it solidify. Through the above structural settings, manual force is not required for shearing, reducing the intensity of minimally invasive surgery. The doctor can concentrate more energy on controlling the handle and the housing, reducing jitter and improving the quality and safety of the surgery. Description of the Drawings

The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0036] First embodiment:

[0037] Please refer to Figures 1 to 3 where Figure 1 is a schematic structural diagram of the whole of the first embodiment of the present invention, Figure 2 is a sectional view of the whole of the first embodiment of the present invention, Figure 3 is the Figure 2 A-A line sectional view of. The present invention provides a bipolar electrocoagulation knife for minimally invasive surgery, including a scissor clamp 101 and a shearing electrocoagulation assembly. The shearing electrocoagulation assembly includes a rotating shaft 102, a housing 103, a telescopic driving unit, two electric wires 104, a grip 105, a battery pack 106, an intelligent display screen 108 and a PLC controller 109. The grip 105 has a groove 107. The telescopic driving unit includes two fixed blocks 110, an electric telescopic rod 111 and a switch 112.

[0038] For this specific embodiment, the doctor holds the grip 105, aligns the scissor clamp 101 with the lesion, the electric telescopic rod 111 starts to expand and contract under the signal transmission of the PLC controller 109, thereby driving the two shearing ends of the scissor clamp 101 to move, driving the scissor clamp 101 to perform a shearing operation. The two shearing ends of the scissor clamp 101 rotate around the rotating shaft 102. At the same time, after the electric wire 104 is connected to the battery pack 106, a high-frequency power supply is transmitted to the scissor clamp 101 to generate heat, heating the shearing part to make it solidify.

[0039] One end of the rotating shaft 102 is fixedly connected to the housing 103 and is located on the inner top wall of the housing 103. The scissor clip 101 is rotatably connected to the rotating shaft 102 and is located on the outer surface wall of the rotating shaft 102. The telescopic driving unit is arranged on the scissor clip 101. The grip 105 is fixedly connected to the housing 103 and is located at one end of the housing 103 away from the scissor clip 101. The grip 105 has a groove 107, and the groove 107 communicates with the housing 103. The battery pack 106 is fixedly connected to the grip 105 and is located inside the groove 107. The scissor clip 101 is connected to the battery pack 106 through two wires 104. The doctor holds the grip 105 to align the scissor clip 101 with the lesion. By operating the telescopic driving unit, the scissor clip 101 is driven to perform a shearing operation. The two shearing ends of the scissor clip 101 rotate around the rotating shaft 102. At the same time, after the wire 104 is connected to the battery pack 106, high-frequency power is transmitted to the scissor clip 101 to generate heat, heating the shearing part to make it solidify. Thus, manual shearing force is not required, reducing the intensity of minimally invasive surgery. The doctor can focus more on controlling the grip 105 and the housing 103, reducing jitter and improving the quality and safety of the surgery. The groove 107 is used to install the battery pack 106.

Both ends of the electric telescopic rod 111 are fixedly connected to the corresponding fixing blocks 110. The switch 112 is fixedly connected to the grip 105 and is located at one end of the grip 105 away from the housing 103. The fixing blocks 110 support the electric telescopic rod 111. The doctor presses the switch 112, and then the electric telescopic rod 111 starts to expand and contract under the signal transmission of the PLC controller 109, thereby driving the two shearing ends of the scissor clip 101 to move.

[0043] When using the bipolar electrocoagulation knife for minimally invasive surgery of this embodiment, the doctor holds the handle 105, aligns the scissor clamp 101 with the lesion, the electric telescopic rod 111 starts to expand and contract under the signal transmission of the PLC controller 109, thereby driving the two shearing ends of the scissor clamp 101 to move, driving the scissor clamp 101 to perform a shearing operation. The two shearing ends of the scissor clamp 101 rotate around the rotating shaft 102. At the same time, after the electric wire 104 is connected to the battery pack 106, high-frequency power is transmitted to the scissor clamp 101 to generate heat, heating the shearing part to make it solidify. Through the above structural arrangement, manual force is not required for shearing, reducing the intensity of minimally invasive surgery. The doctor can concentrate more energy on controlling the handle 105 and the housing 103, reducing jitter and improving the quality and safety of the surgery.
