Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a smoking lighting surgical electrode. Background Art

[0002] Surgical electrodes are important equipment for surgical operations. They use the electrode head to cut the surgical site of the patient. The tip of the surgical electrode heats up when the power is turned on and acts on the affected part of the body, causing the vascular tissue at the lesion of the patient to gradually become organized and atrophy, thereby achieving the cutting and hemostasis of the body tissue. Surgical electrodes have the advantages of less damage to tissues and good hemostasis effects, so they are widely used in minimally invasive surgeries such as open surgery and various laparoscopic surgeries. From a functional point of view, surgical electrodes are mainly divided into smoking surgical electrodes and lighting surgical electrodes. Smoking surgical electrodes are equipped with a smoking chamber on the basis of surgical electrodes to absorb the protein smoke produced when the electrode head cuts the skin and subcutaneous tissue, preventing the smoke from affecting the surgical line of sight and polluting the environment of the operating room, thereby reducing the difficulty of the operation; lighting surgical electrodes are equipped with a lighting device on the basis of surgical electrodes to illuminate the surgical site of the patient, thereby improving the therapeutic effect of the operation.

[0003] However, traditional surgical electrodes have a complex structure and a single function, and can only realize one function of lighting or smoking. When using smoking surgical electrodes for surgical operations, special surgical lighting devices are required, which are inconvenient to operate and have high surgical costs. The light source of traditional lighting surgical electrodes is fixed in the surgical electrode tube, and the light source is far away from the surgical site, resulting in insufficient lighting effect of the surgical electrodes. Summary of the invention

[0004] Based on this, it is necessary to provide a smoking lighting surgical electrode to address the technical problems of single function and insufficient lighting effect.

The electrode passes through the smoking tube, and one end of the electrode is electrically connected to the standard electrode socket, and the other end of the electrode is located outside the smoking tube. The electrode is used to generate heat under the action of the controller and to cut or stop bleeding on the surgical site. The light source is electrically connected to the light source socket, one end of the optical fiber tube abuts against the edge of the light source socket and surrounds the light source, and the other end of the optical fiber tube is connected to the smoking tube and corresponds to the surgical site, and the optical fiber tube is used to illuminate the surgical site.

[0006] In one embodiment, the end of the smoking tube has a positioning ring, the positioning ring is connected to the inner surface of the smoking tube, and the optical fiber tube passes through the positioning ring and is connected to the smoking tube.

[0007] In one embodiment, the positioning ring is integrally formed with the smoking tube.

In this way, only one surgical electrode is needed to achieve smoking and lighting of the surgical site, which is simple to operate and reduces the cost of surgery.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0023] Please also read Figure 1 and Figure 2 The present invention provides a smoking lighting surgical electrode 10, which includes a tube shell 100, a smoking pipe 200, a controller 300, an electrode 400, a light source 500 and an optical fiber tube 600. The tube shell 100 has a housing space 110. One end of the tube shell 100 is provided with a smoking interface 120 and a wire interface 130. The smoking interface 120 is used to communicate with an external suction pump, and the wire interface 130 is used to pass the cable of the controller 300. The other end of the tube shell 100 is provided with a quick interface 140, which is connected to the smoking pipe 200. The smoking interface 120, the wire interface 130 and the quick interface 140 are respectively connected to the housing space 110. One end of the smoking pipe 200 corresponds to the patient's surgical site, and the other end of the smoking pipe 200 is adjacent to the quick interface 140 and connected to the tube shell 100. The smoking pipe 200 provides a channel for the flow of surgical smoke. The controller 300 is accommodated in the accommodating space 110. One end of the controller 300 adjacent to the quick interface 140 is respectively provided with a standard electrode socket 310 and a light source socket 320. The electrode 400 is passed through the smoking tube 200. One end of the electrode 400 is electrically connected to the standard electrode socket 310. The other end of the electrode 400 is located outside the smoking tube 200. The electrode 400 is used to generate heat under the action of the controller 300 and to cut or stop bleeding at the surgical site. The light source 500 is electrically connected to the light source socket 320. One end of the optical fiber tube 600 abuts against the edge of the light source socket 320 and surrounds the light source 500. The other end of the optical fiber tube 600 is connected to the smoking tube 200 and corresponds to the surgical site. The optical fiber tube 600 is used to illuminate the surgical site.

[0024] The above-mentioned smoking and lighting surgical electrode 10, by installing an optical fiber tube 600 in the smoking tube 200, can illuminate the patient's surgical site while guiding out the burnt smoke generated during the operation, so as to help the surgical operator to find out the condition of the patient's diseased part and completely remove the lesion. In this way, only one surgical electrode is needed to achieve smoking and lighting of the surgical site, which is simple to operate and reduces the cost of surgery. In addition, the light emitted by the light source 500 at the end of the tube shell 100 is transmitted to the end of the smoking tube 200 through the optical fiber tube 600, shortening the distance from the light source outlet to the surgical site, thereby improving the lighting conditions of the surgical site and the surgical environment, and enhancing the surgical effect.

[0025] The tube housing 100 is used to house the controller 300 and provide a flow channel for the smoke generated during the operation. Figure 3 In one embodiment, the tube shell 100 includes a first half shell 150 and a second half shell 160, and the first half shell 150 and the second half shell 160 are snap-fitted, and the first half shell 150 and the second half shell 160 jointly surround the controller 300 and protect the controller 300. It can also be understood that the controller 300 is encapsulated between the first half shell 150 and the second half shell 160 to prevent the internal circuit of the controller 300 from being disconnected due to foreign objects colliding with the controller 300, so as to ensure the effective use of the surgical electrode. By snapping the first half shell 150 and the second half shell 160, that is, the first half shell 150 and the second half shell 160 are detachably connected, in this way, when any component of the first half shell 150 and the second half shell 160 is damaged, the damaged component can be replaced separately, thereby reducing the use cost of the surgical electrode. In addition, when installing the controller 300, the controller 300 only needs to be inserted between the first half shell 150 and the second half shell 160 to achieve the positioning of the controller 300, thereby reducing the difficulty of assembling the surgical electrode and improving the efficiency of disassembling and assembling the surgical electrode.

[0026] In one embodiment, the tube shell 100 is provided with two pressing holes 170 and a cutting button 180 and a coagulation button 190. The cutting button 180 passes through a pressing hole 170 and abuts against the edge of the pressing hole 170. The cutting button 180 is pressed against the cutting action contact of the controller 300 under the action of an external force, so that the surgical electrode switches to the cutting function. The coagulation button 190 is pressed against the coagulation action contact of the controller 300 under the action of an external force, so that the surgical electrode switches to the coagulation function. In this way, only by pressing the cutting button 180 or the coagulation button 190, a command can be issued to the controller 300 to switch the working mode of the surgical electrode, which reduces the difficulty of operating the surgical electrode.

[0027] The smoke pipe 200 is used to collect the charred smoke generated during the operation and provide a channel for the flow of the charred smoke. During the operation, negative pressure is formed at the air inlet of the external vacuum pump. The air in the accommodating space 110 and the smoke pipe 200 will move toward the air inlet of the vacuum pump under the action of the negative pressure. When the air in the smoke pipe 200 moves toward the vacuum pump, the air flow rate in the smoke pipe 200 is accelerated and the air pressure in the smoke pipe 200 is reduced. In other words, a pressure difference is formed inside and outside the smoke pipe 200, and the air outside the smoke pipe 200 will continuously flow into the smoke pipe 200. In this way, the charred smoke generated by the electrode 400 cutting the surgical site will enter the smoke pipe 200 under the influence of the air flow, and then be discharged through the tube shell 100 and the vacuum pump in sequence, thereby reducing the impact of the charred smoke on the surgical environment. Please refer to Figure 4In one embodiment, a through groove 210 is provided on the inner surface of the smoking tube 200, and the through groove 210 is used to accommodate the optical fiber tube 600. Preferably, the cross section of the through groove 210 is a semicircular arc structure. It can be understood that when the optical fiber tube 600 is accommodated in the through groove 210, the outer surface of the optical fiber tube 600 abuts against the inner surface of the through groove 210, so that the exposed area of ​​the outer surface of the optical fiber tube 600 is reduced, that is, the contact area between the burnt smoke and the optical fiber tube 600 is reduced, and the burnt smoke has less stimulation on the optical fiber tube 600, thereby delaying the aging rate of the optical fiber tube 600.

[0028] See also Figure 5 In one embodiment, the end of the smoking tube 200 has a positioning ring 220, and the positioning ring 220 is connected to the inner surface of the smoking tube 200. The optical fiber tube 600 is inserted through the positioning ring 220 and connected to the smoking tube 200. It can be understood that the positioning ring 220 is used to limit the end of the optical fiber tube 600 to prevent the optical fiber tube 600 from shaking in the smoking tube 200, so as to improve the stability of the connection between the optical fiber tube 600 and the smoking tube 200. After the optical fiber tube 600 is inserted through the positioning ring 220, the outer surface of the optical fiber tube 600 abuts against the inner surface of the positioning ring 220, so that the end of the optical fiber tube 600 and the end of the smoking tube 200 are on the same plane. In this way, during the cutting and coagulation operation of the electrode 400, the end of the optical fiber tube 600 can be prevented from contacting the surgical site of the patient, ensuring the normal cutting and coagulation operation of the electrode 400. In addition, under the constraint of the positioning ring 220, the end of the optical fiber tube 600 is always fixed to the end of the smoking tube 200, and the distance between the end of the optical fiber tube 600 and the end of the electrode 400 is small, that is, the light source outlet of the optical fiber tube 600 is close to the surgical site, thereby increasing the luminous flux per unit area of ​​the surgical site. In other words, the illumination intensity of the surgical site is increased, which is beneficial for the surgical operator to find out the condition of the patient's diseased site and completely remove the lesion to ensure the surgical treatment effect. In one embodiment, the positioning ring 220 and the smoking tube 200 are integrally formed. By integrally forming the positioning ring 220 and the smoking tube 200, the stability of the connection between the positioning ring 220 and the smoking tube 200 is improved, and then the stability of the connection between the optical fiber tube 600 and the smoking tube 200 is improved to ensure the effective operation of the optical fiber tube 600 and the lighting effect of the surgical electrode.

[0029] In one embodiment, there is an angle between the central axis of the positioning ring 220 and the length direction of the smoking tube 200. Preferably, the angle is between 3 degrees and 8 degrees. It can also be understood that the end of the positioning ring 220 is biased toward the center of the smoking tube 200, so that after the optical fiber tube 600 passes through the positioning ring 220, the optical fiber tube 600 will bend at the positioning ring 220. When the optical fiber tube 600 is subjected to external tension, the component force of the supporting force of the positioning ring 220 on the end of the optical fiber tube 600 is balanced with the external tension. In other words, the optical fiber tube 600 is always connected to the positioning ring 220 under the constraint of the inner surface of the positioning ring 220, thereby improving the stability of the connection between the optical fiber tube 600 and the inner wall of the smoking tube 200, and ensuring the normal use of the surgical electrode lighting function. By setting the angle between the central axis of the positioning ring 220 and the length direction of the smoking tube 200 to be between 3 degrees and 8 degrees, while ensuring that the supporting force of the positioning ring 220 on the end of the optical fiber tube 600 has a larger component along the length direction of the smoking tube 200, the blocking of the input end of the smoking tube 200 by the positioning ring 220 and the optical fiber tube 600 can be reduced, so as to facilitate the smooth entry of the burnt smoke generated by the operation into the smoking tube 200.

[0030] The electrode 400 is used to cut the patient's surgical site and stop bleeding at the surgical site to reduce the patient's blood flow during the surgical process and relieve the patient's pain. Specifically, the electrode 400 is powered on by the controller 300. When the controller 300 receives a cutting instruction, the controller 300 controls the power of the electrode 400 so that the high-frequency generator of the electrode 400 generates a high-frequency current with a sine waveform, which acts on the patient's affected part and destroys the tissue at the affected part, thereby achieving cutting of the affected part. When the controller 300 receives a coagulation instruction, the controller 300 controls the power of the electrode 400 so that the high-frequency generator of the electrode 400 generates a high-frequency current with a triangular waveform, which acts on the patient's affected part, so that the temperature of the tissue around the affected part increases, so that the protein around the affected part is denatured and inactivated, and coagulation is generated, thereby achieving hemostasis of the surgical site.

[0031] Please refer again Figure 2In one embodiment, the smoking lighting surgical electrode further includes a heat insulator 700, which is sleeved on the electrode 400 and abuts against the outer surface of the electrode 400, and one end of the heat insulator 700 adjacent to the tube shell 100 is inserted into the standard electrode socket 310 and abuts against the inner surface of the standard electrode socket 310. The heat insulator 700 is used to cover the electrode 400, reduce the heat radiation generated by the electrode 400 to the smoking pipe 200 during the heating process, prevent the smoking pipe 200 from softening and deforming, and extend the service life of the smoking pipe 200. In one embodiment, the cross section of the outer ring of the heat insulator 700 adjacent to one end of the tube shell 100 is a regular hexagon, the cross section of the standard electrode socket 310 is a regular hexagon, and the outer surface of the heat insulator 700 abuts against the inner surface of the standard electrode socket 310. By respectively designing the cross-section of the thermal insulation member 700 adjacent to one end of the tube shell 100 as a regular hexagon and the cross-section of the standard electrode socket 310 as a regular hexagon, when the thermal insulation member 700 is inserted into the standard electrode socket 310, the outer surface of the thermal insulation member 700 abuts against the inner surface of the standard electrode socket 310, and the thermal insulation member 700 is always confined in the standard electrode socket 310 under the constraint of the inner surface of the standard electrode socket 310. In other words, the connection between the thermal insulation member 700 and the standard electrode socket 310 is relatively stable, thereby ensuring that the thermal insulation member 700 continuously insulates the electrode 400.

[0032] The light source 500 is used to connect the current and emit light under the action of the controller 300 to provide illumination for the surgical site. In one embodiment, the light source 500 is a light emitting diode. A light emitting diode is a semiconductor component, which has the advantages of energy saving, environmental protection, long life and small size. Therefore, the use of a light emitting diode is conducive to reducing the overall volume of the surgical electrode and extending the service life of the surgical electrode, so as to enhance the market competitiveness of the surgical electrode. The optical fiber tube 600 is used to transmit the light generated by the light source 500, and the light is totally reflected in the optical fiber tube 600, that is, the light intensity generated at the light source 500 is minimally lost in the optical fiber tube 600, and the illumination of the surgical site is better, thereby improving the surgical effect.

[0033] See also Figure 6In one embodiment, the smoking lighting surgical electrode further comprises a connector 800, one end of which abuts against the edge of the quick interface 140, and the other end of which is sleeved on the smoking tube 200 and abuts against the outer surface of the smoking tube 200, and the connector 800 is respectively connected to the accommodating space 110 and the smoking tube 200. It can also be understood that the smoking tube 200 is detachably connected to the tube shell 100 through the connector 800, so that when the smoking tube 200 is damaged, the damaged smoking tube 200 can be replaced separately to reduce the cost of using the surgical electrode. In addition, when dealing with surgical operations on patients with different disease courses, by replacing electrodes 400 of different lengths and smoking tubes 200 of lengths matching the electrodes 400, operations can be performed on patient parts with different cutting depth requirements, so as to realize the flexible application of surgical electrodes and reduce the cost of using surgical instruments. In one embodiment, a clamp ring 810 is provided in the connector 800, and the clamp ring 810 is used to pass the optical fiber tube 600. It can be understood that the positioning ring 220 and the clamping ring 810 respectively position the two ends of the optical fiber tube 600 to prevent the optical fiber tube 600 from shaking in the smoking tube 200, thereby further improving the stability of the installation of the optical fiber tube 600 and ensuring the effective illumination of the surgical electrode.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
