[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a tungsten needle knife with a light source and smoking. Background Art

[0002] Existing high-frequency surgical electrodes require switching different blade heads to achieve electrocoagulation and electrocuting at different depths and locations. Smoke is generated during the electrocoagulation and electrocuting process, and sometimes the surgical site needs to be illuminated.

[0003] CN221357116U discloses a novel telescopic smoking light source knife, which includes a handle; a control panel disposed within the handle, the front end of which is electrically connected to a light source; a button assembly contacting the top of the control panel, which activates the cutting, coagulation, and light source functions of the control panel by pressing the cutting, coagulation, and light source buttons, respectively; a power cord connected to the end of the control panel, which extends from the bottom end of the handle and is connected to an external electrical plug for connecting to a main unit; a telescopic assembly disposed below the control panel, which drives the electrode forward and backward, and extends outward from the front end of the handle. The electrode and the blade are disposed at the front end of the telescopic assembly; a through-tube is disposed within the handle, the front end of the through-tube being connected to the telescopic assembly and the end thereof being connected to a smoking pipe; and a hollow interior of the electrode, the telescopic assembly, the through-tube, and the smoking pipe is connected to form a smoking passage. However, insufficient consideration was given to insulation and flame retardancy, making the procedure unsafe. Utility Model Content

[0004] In order to make up for the shortcomings of the existing technology, the utility model provides a light source smoking tungsten needle knife, the technical solution is as follows:

[0005] A light source smoking tungsten needle knife, the control board and power cord are welded downwards, the power cord passes through the lower end of the handle, the internal electronic control parts are integrated into the control board, the electric cutting button, electric coagulation button and light source button are installed from the inside into the handle and extend to the outside, the lamp bead is integrated into the front end of the control board and installed to the tip of the handle, the insulating head is press-fitted into the functional tube of the tungsten needle knife head, the electrode extends from the middle hole of the insulating head, and the outer end of the electrode is covered with a high-temperature resistant tube.

[0006] Furthermore, the tungsten needle blade can be stretched and retracted to meet the needs of open surgery.

[0007] Furthermore, the stretching and retraction of the tungsten needle blade is achieved through the following structure:

[0008] Furthermore, there is a cutter head base at the rear end of the tungsten needle cutter head, and the drum spring is clamped in the cutter head base. Then the tungsten needle cutter head equipped with the drum spring is inserted into the stainless steel tube. At this time, the drum spring is squeezed, so that the inner diameter of the drum spring and the cutter head base are fully squeezed and contacted / the outer diameter of the drum spring is fully contacted with the stainless steel tube. The tip of the tungsten needle cutter head is the electrode, so the stainless steel tube → conductive spring → electrode connection is extremely stable, the electrode slides and retracts, the conductive spring remains conductive, and the output is stable.

[0009] Furthermore, the tip of the tungsten needle blade has a length of 3mm-5mm and a tip diameter of about 0.01mm.

[0010] Furthermore, the insulating head is made of high temperature resistant insulating material.

[0011] Furthermore, the high temperature resistant insulating material is PEEK insulating material.

[0012] Furthermore, the material of the electrode is alloy steel, preferably metal tungsten.

[0013] Furthermore, the control board is a PCB board.

[0014] Furthermore, the lamp beads are welded to the PCB board through connectors.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The utility model has better electrocuting, electrocoagulation and lighting effects. The tungsten needle blade can be stretched and retracted to any length to meet the needs of open surgery. The electrode head is anti-adhesion, preventing scabs and adhesions, and the unique electrode head design ensures cutting efficiency. The tip of the tungsten needle blade is sharper and more resistant to high temperatures, more stable and durable. The previous width was 3mm, and now the electrode diameter is 0.8mm, and the tip is 0.01mm. The tip of the tungsten needle blade is made of high-temperature resistant polymer material, preferably PEEK insulation material. The insulation head will not deform or melt under high power, and is more stable. The tungsten needle blade meets the requirements of a longer needle-shaped operating length. The original needle length was 3mm, and now the needle length is preferably 5mm. This is mainly because the original tube wrapping method is prone to discharge and cause electric damage to non-target tissues, but now it will not. It also meets the requirements of a shorter smoking distance, making smoking smoother and more thorough. The tungsten needle blade has better insulation wrapping, and the non-cutting end is wrapped, avoiding the risk of accidental electric damage, which is safer. Tungsten needle blades are easier to use for delicate ablation operations in neurosurgery, brain surgery, etc., and are more subtle. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further described below with reference to the accompanying drawings, but the present invention is not limited to the following embodiments.

[0022] Example 1

[0023] A light source smoking tungsten needle knife, the control board 11 and the power cord 8 are welded downward, the power cord 8 passes through the lower end of the handle 2, the internal electronic control parts are integrated into the control board 11, the electric cutting button 3, the electric coagulation button 4 and the light source button 5 are installed from the inside into the handle 2 and extend to the outside, the lamp bead 6 is integrated into the front end of the control board 11 and installed to the tip of the handle 2, the insulating head 14 is pressed into the functional tube 7 of the tungsten needle knife head 13, the electrode 1 extends from the middle hole of the insulating head 14, and the outer end of the electrode 1 is provided with a high temperature resistant tube.

[0024] The rear end of the tungsten needle blade 13 has a blade base, into which a drum spring is mounted. The tungsten needle blade with the drum spring is then inserted into the stainless steel tube 12. The insulating head 14 is made of a high-temperature insulating material, in this embodiment, PEEK. The control board 11 is a PCB, and the lamp beads 6 are soldered to the PCB via connectors.

[0025] The structure and function are further described as follows:

[0026] 1. Improve the internal electronic control components. The internal electronic control parts are integrated into the control board 11, reducing scattered parts, making the electronic control more stable and easier to assemble.

[0027] 2. The outlet is now connected to the power cord, which is more suitable. The original outlet was connected to the power cord, which caused a dragging feeling. This new model is more comfortable to operate, eliminates the dragging feeling, and makes the operation smoother.

[0028] 3. The buttons are built-in, which improves the pressing feeling and eliminates the risk of falling off.

[0029] 4. The tungsten needle blade head 13 can be stretched and retracted to meet the needs of open surgery.

[0030] Construction: Stainless steel tube 12 → conductive spring 10 → electrode 1. (The rear end of the tungsten needle blade 13 has a blade base, into which a drum spring is mounted. The blade with the drum spring is then inserted into the stainless steel tube 12. The drum spring is squeezed, causing the inner diameter of the drum spring to fully contact the blade base and the outer diameter of the drum spring to fully contact the stainless steel tube 12. The tip of the blade becomes electrode 1, thus ensuring a highly stable connection from stainless steel tube 12 to conductive spring 10 to electrode 1.) As electrode 1 slides and retracts, the conductive spring maintains conduction, resulting in stable output.

[0031] 5. The lamp bead 6 at the tip of the handle is illuminated, the tungsten needle cutter head 13 can be stretched to any length, and the working position of the tungsten needle cutter head 13 is fully illuminated.

[0032] 6. The internal resistance of the key switch is reduced, and the contact resistance is increased. If the key is not pressed sufficiently, the metal contact resistance of the pot switch will be very large, resulting in a large internal resistance.

[0033] 7. Contact: The structure of the electro-cutting button 3, the electro-coagulation button 4 and the light source button 5 can ensure that each button press is a center point press.

[0034] 8. The outer end of the electrode 1 is provided with a high temperature resistant tube, and the insulating head 14 is also made of a high temperature resistant insulating material, so during surgery, it has sufficient insulation and flame retardancy, making the surgery safer.

[0035] 9. The material of electrode 1 is tungsten metal, which can ensure hardness and sharpness. Since the melting point of tungsten metal is above 3000 degrees Celsius, even if a large power is used and a large amount of heat is generated during electro-incision and electro-coagulation operations, the tip of electrode 1 will not be melted. It is durable and stable and can run through the entire operation.

[0036] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
