Description

Technical Field

[0001] The present application relates to the technical field of surgical instruments, and more specifically, to a soft tissue high-frequency welding device. Background Art

[0002] The monopolar high-frequency electrocoagulation pen is a type of soft tissue high-frequency welding equipment. The monopolar high-frequency electrocoagulation pen is operated by surgeons and is suitable for cutting and coagulating soft tissues during medical operations. When using the monopolar high-frequency electrocoagulation pen, first connect the monopolar cable plug of the monopolar high-frequency electrocoagulation pen to the monopolar power output port of the high-frequency surgical equipment, so that the high-frequency current generated by the high-frequency surgical equipment flows between the surgical electrode (electrode head) of the monopolar electrode and the patient's body-to-ground capacitance, achieving the purpose of cutting or coagulating the tissues in between.

[0003] Mouth breathing in children, or snoring during sleep at night, is a serious problem that is often overlooked but should not be underestimated. Even mild snoring can affect the physical development of children and cause immeasurable long-term harm. Children's pharynx is relatively narrow, and enlarged tonsils and adenoids are the main causes of pediatric snoring. The most effective way to treat pediatric snoring caused by these two soft tissues is to perform precise cutting, ablation, and electrocoagulation to stop bleeding through surgical procedures.

[0004] During the electroresection of enlarged tonsils and adenoids in children using the existing monopolar high-frequency electrocoagulation pen, as the operation time continues, the working time of the monopolar high-frequency electrocoagulation pen will also be correspondingly extended, causing the heat of the electrocoagulation pen blade to continue to accumulate, which can easily lead to overheating of the electrocoagulation pen blade. In addition, since children's tissues are more delicate than adults and have poorer tolerance to thermal energy, if the above-mentioned overheating phenomenon is not discovered in time, it is easy to cause burns to the tissues of the pediatric patient during the operation. Such thermal burns not only increase the risk of the operation, but also affect postoperative recovery and healing.

[0005] In view of this, we propose a soft tissue high frequency welding device. Summary of the invention

The saline flows into the columnar collection tank through the soft catheter and then flows out from the fine liquid holes on the conductive pipeline arranged parallel to the blade head, so that the saline can accurately drip on the surface of the blade head that is performing the electrosurgical operation, which helps to reduce the risk of overheating of the blade head during the operation and improve the safety of the operation. In addition, during the electrosurgical operation, the saline is continuously and accurately delivered to the blade head through the conductive pipeline. The saline can lubricate the blade head and avoid adhesion of bleeding tissue and the blade head, thereby ensuring the smooth progress of the surgical operation.

[0020] 4. When the action structure changes from a retracted state to an extended state, the extended action structure will further drive the tapered plugging portion to move toward the columnar liquid collecting groove, so that the distance between the tapered plugging portion and the inner wall of the tapered closing groove continues to increase, which can speed up the flow rate of saline to the overheated blade head. When the action structure senses that the temperature at the blade head exceeds its preset temperature upper limit, it can actively adjust the dripping speed of saline and actively reduce the current passing through the blade head. These two active adjustment methods work together to cool the overheated blade head, so that the heat at the blade head can be quickly dissipated and rapid cooling can be achieved, thereby more effectively protecting the tissues of the pediatric surgical site from thermal damage and ensuring the safety and success rate of pediatric soft tissue cutting surgery.

The conducting pipe 105 is arranged inside the wall thickness of the insulating rod 102, and one end of the conducting pipe 105 away from the electrocoagulation pen body 101 extends out from the end of the insulating rod 102. A fine liquid hole with a discharge port facing the blade head 103 is provided at the bottom of the conducting pipeline 105. A columnar liquid collecting groove 106 and a conical closing groove 107 are also provided at one end of the inner cavity of the conducting pipeline 105 close to the electrocoagulation pen body 101. The inner cavity of the conducting pipeline 105 is connected to the columnar liquid collecting groove 106 through the conical closing groove 107. The columnar liquid collecting groove 106 is a cylindrical structure, and the inner cavity of the conducting pipeline 105 is also a cylindrical structure. The inner diameter of the columnar liquid collecting groove 106 is larger than the inner diameter of the inner cavity of the conducting pipeline 105. The side wall of the conducting pipeline 105 is also connected to a soft conduit 104 that is in communication with the columnar liquid collecting tank 106. One end of the soft conduit 104 away from the conducting pipeline 105 passes through the side wall of the insulating rod 102. A temperature sensing unit is provided at the position corresponding to the inner cavity of the electrocoagulation pen body 101 and the position of the conducting pipeline 105. The temperature sensing unit includes a schematic structure and a retractable action structure. The action structure is respectively provided with a heat guide structure and a synchronization component. The synchronization component includes a synchronization rod 211. The synchronization rod 211 passes through the heat preservation tube seat 205, the electrocoagulation pen body 101, and the insulating rod 102 respectively, and then seals through the end of the conducting pipeline 105 and extends into the inner cavity of the conical closing groove 107.

When the action unit changes from the initial retracted state to the extended state, the action unit drives the conical plugging portion 212 to move toward the columnar liquid collecting groove 106 .

[0037] The action structure in the temperature sensing unit can sense the electrocuting temperature at the blade head 103 in real time, and when the blade head 103 is overheated, the action structure will change from the initial retracted state to the extended state and trigger the schematic structure to protrude from the surface of the electrocoagulation pen body 101, thereby reminding the doctor to cool down the blade head 103 in time, thereby effectively avoiding the blade head 103 from overheating during the long-term electrocuting operation for children's enlarged tonsils and adenoids, thereby effectively avoiding the situation in which the blade head 103 causes burns to the tissue of the child's patient, thereby improving the safety of children's soft tissue cutting surgery and facilitating the recovery and healing of the surgical site after surgery.

[0038] The soft catheter 104 is plugged into the joint of the infusion tube of the saline infusion bottle. The saline flows into the columnar liquid collecting tank 106 through the soft catheter 104 and then flows out from the fine liquid holes on the conductive pipeline 105 arranged parallel to the blade head 103, so that the saline can accurately drip onto the surface of the blade head 103 that is performing the electrosurgical operation, which helps to reduce the risk of overheating of the blade head 103 during the operation and improve the safety of the operation. In addition, during the electrosurgical operation, the saline is continuously and accurately delivered to the blade head 103 through the conductive pipeline 105. The saline can lubricate the blade head 103 and avoid adhesion of bleeding tissue and the blade head, thereby ensuring the smooth progress of the surgical operation.

[0039] Reference Figure 4 , Figure 6 , Figure 7 , Figures 9 to 11 , the embodiment of the present application provides a soft tissue high-frequency welding device, the action structure includes a heat preservation tube seat 205 connected to the inner cavity of the electrocoagulation pen body 101; The inner cavity of the heat-insulating cylinder seat 205 is filled with a heat-sensitive medium part 210, and the heat-sensitive medium part 210 is temperature-sensitive paraffin. The heat-insulating cylinder seat 205 is made of a heat-insulating material. Under the heat-insulating effect of the heat-insulating cylinder seat 205, the heat transfer between the heat-sensitive medium part 210 and the outside world can be greatly reduced; An insulating passive seat 206 is inserted into the opening at the end of the heat preservation tube seat 205 for horizontal sliding movement. One end of the synchronization rod 211 away from the conical plugging portion 212 seals through the end of the heat preservation tube seat 205 and extends into the interior of the heat-sensitive medium portion 210 and is connected to the insulating passive seat 206. A chamfered transition portion 214 is provided on the end of the insulating passive seat 206; An inner recessed groove 216 is formed on the chamfered transition portion 214, and a movable spring piece 215 is connected to the inner cavity of the inner recessed groove 216; Elastic components are disposed on both the front and rear sides of the insulating passive seat 206 .

[0040] Reference Fig.10 , the embodiment of the present application provides a soft tissue high frequency welding device, the elastic member includes a first side seat, and the first side seat is connected to a first return spring 219; The two first side connection seats are respectively connected to the front and rear sides of the insulating passive seat 206; One end of the first return spring 219 away from the first side seat is connected to the inner cavity side wall of the electrocoagulation pencil body 101 .

[0041] Reference Figures 4 to 7, the embodiment of the present application provides a soft tissue high-frequency welding device, the heat-inducing structure includes a heat-insulating sleeve 203, the heat-insulating sleeve 203 is arranged inside the wall thickness of the insulating rod 102, and the end of the heat-insulating sleeve 203 close to the electrocoagulation pen body 101 passes through the electrocoagulation pen body 101 and the heat-insulating cylinder seat 205 respectively; A heat-conducting wire 204 is arranged in the inner cavity of the heat-conducting sleeve 203. The heat-conducting sleeve 203 is made of a heat-insulating material. Under the heat-insulating effect of the heat-conducting sleeve 203, the heat transfer between the heat-conducting wire 204 and the outside world during the heat-conducting process can be greatly reduced. The two ends of the heat-conducting wire 204 extend from the two ends of the heat-insulating sleeve 203 respectively, and one end of the heat-conducting wire 204 is connected to the annular heat-conducting net 209, and the other end is sleeved with the heat-insulating sleeve 220, and the end of the heat-insulating sleeve 220 is connected to the end of the heat-insulating sleeve 203, and the heat-insulating sleeve 220 is made of heat-insulating material; The annular heat-conducting net 209 is disposed in the inner cavity of the heat-insulating cylinder seat 205 and is arranged around the outer periphery of the synchronization rod 211; One end of the heat insulating sleeve 220 away from the heat preservation sleeve 203 extends into the inside of the cutter head 103, and one end of the heat conductive wire 204 away from the heat insulating sleeve 220 passes through the end of the heat preservation tube seat 205 and extends into the inside of the heat sensitive medium part 210 and is connected to the corresponding annular heat conductive net 209.

[0042] When heat is conducted to the heat-sensitive medium portion 210 through the heat-conducting wire 204 in the heat-leading structure through the annular heat-conducting net 209 connected to the end of the heat-conducting wire 204, the annular heat-conducting net 209 has a relatively larger surface area and can be in more complete contact with the heat-sensitive medium portion 210, thereby achieving uniform distribution of heat. This helps to avoid uneven heating of the heat-sensitive medium portion 210 and improve the uniformity and efficiency of heat transfer.

[0043] Reference Figure 4 , Figure 6 , Figures 9 to 11 The embodiment of the present application provides a soft tissue high-frequency welding device, the schematic structure of which includes an insulating lifting seat 201, a rotating wheel groove is provided at the bottom of the insulating lifting seat 201, and a plurality of rotating wheels 208 arranged in rows are connected and rotated evenly in the rotating wheel groove, and the insulating lifting seat 201 and the insulating passive seat 206 are both made of insulating materials; The bottom of the insulating lifting seat 201 is also connected to a strip resistor 207 that cooperates with the movable spring 215, and the free end of the movable spring 215 is closely attached to the bottom surface of the strip resistor 207. The output end of the strip resistor 207 and the movable spring 215 are both electrically connected to the circuit in the electrocoagulation pen body 101 that supplies power to the blade head 103. The left and right sides of the insulating lifting seat 201 are connected to second side seats, and each second side seat is connected to a second return spring 218; A reserved opening adapted to the insulating lifting seat 201 is provided on the top of the electrocoagulation pen body 101, and the insulating lifting seat 201 is inserted into the reserved opening to slide up and down; One end of the second return spring 218 away from the second side seat is connected to the end of the inner cavity of the electrocoagulation pencil body 101 .

[0044] When the device is running, the high temperature at the cutter head 103 is continuously conducted from the heat-conducting wire 204 to the thermosensitive medium part 210 of the action structure through the heat-insulating sleeve 220 in the heat-conducting structure. When the cutter head 103 is overheated due to reasons such as a long duration of the operation, the temperature of the end of the heat-conducting wire 204 located inside the thermosensitive medium part 210 in the heat-conducting structure and the annular heat-conducting net 209 exceeds the phase change temperature of the thermosensitive medium part 210. The volume of the thermosensitive medium part 210 undergoing phase change expands and drives the insulating passive seat 206 to extend from the opening at the end of the heat-insulating cylinder seat 205. When the chamfered transition part 214 contacts the rotating wheel 208 in the schematic structure, the schematic structure is turned on. The structure is pushed upward, so that the schematic structure protrudes from the surface of the electrocoagulation pen body 101 through the reserved opening. When the doctor observes the schematic structure protruding from the surface of the electrocoagulation pen body 101 during the operation, he can quickly determine that the blade head 103 has been overheated and needs to be cooled down in time. The action structure in the present application can sense the electric cutting temperature at the blade head 103 in real time, and when the blade head 103 is overheated, the action structure will change from the initial retracted state to the extended state and trigger the schematic structure to protrude from the surface of the electrocoagulation pen body 101, thereby reminding the doctor to cool down the blade head 103 in time.

[0045] When the action structure changes to an extended state and triggers the schematic structure to protrude from the surface of the electrocoagulation pen body 101 to remind the doctor, the extended action structure drives the movable spring piece 215 to move, so that the distance between the movable spring piece 215 and the output end of the strip resistor 207 continues to increase, and the resistance value also increases accordingly, so that when the present application performs electroresection surgery on the soft tissue of children and detects overheating at the blade head 103, it can actively reduce the current passing through the blade head 103, thereby achieving active cooling of the overheated blade head 103 and avoiding the overheated blade head from causing burns to the tissue of the child patient.

[0046] During the process of the action structure changing from the retracted state to the extended state, the extended action structure will further drive the tapered plugging portion 212 to move toward the columnar liquid collecting groove 106, so that the distance between the tapered plugging portion 212 and the inner wall of the tapered closing groove 107 continues to increase, which can speed up the flow rate of saline to the overheated blade head 103. When the action structure senses that the temperature at the blade head 103 exceeds its preset temperature upper limit, it can actively adjust the dripping speed of saline and actively reduce the current passing through the blade head 103. These two active adjustment methods cooperate with each other to jointly cool the overheated blade head 103, so that the heat at the blade head can be quickly dissipated, achieving rapid cooling, thereby more effectively protecting the tissues of the pediatric surgical site from thermal damage and ensuring the safety and success rate of pediatric soft tissue cutting surgery.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
