Description

Technical Field

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

[0002] The monopolar high-frequency electrocoagulation pen is a type of high-frequency soft tissue welding device. It is operated by a surgeon and is suitable for cutting and coagulating soft tissues during medical surgeries. 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 device, so that the high-frequency current generated by the high-frequency surgical device flows between the surgical electrode (electrode tip) of the monopolar electrode and the body capacitance of the patient to the ground, achieving the purpose of cutting or coagulating the tissue therebetween.

[0003] Mouth breathing in children, or snoring during night sleep, is a serious problem that is often overlooked but cannot be underestimated. Even mild snoring can affect the physical development of children and cause immeasurable long-term harm. The pharynx in children is relatively narrow, and tonsillar hypertrophy and adenoid hypertrophy are the main causes of pediatric snoring. Precision cutting, ablation, and electrocoagulation hemostasis of these two soft tissues through surgical operations are the most effective methods for treating pediatric snoring caused by these two factors.

[0004] During the electrocision operation of the hypertrophied 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 continue to extend accordingly, resulting in continuous accumulation of heat at the electrocoagulation pen tip, which is likely to cause overheating of the electrocoagulation pen tip. Moreover, since the tissues of children are more delicate than those of adults and have a lower tolerance to heat energy, if the above overheating phenomenon is not detected in a timely manner, it is easy to cause burns to the tissues at the diseased area of children during the operation. This kind of thermal burn not only increases the risk of the operation but also affects the postoperative recovery and healing.

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

[0032] Beneficial effects: One or more technical solutions provided in the technical solution of the present application have at least the following technical effects or advantages: 1. The action structure in the temperature sensing unit can sense the electrocision temperature at the knife head in real time. When the knife head overheats, the action structure will change from the initial retracted state to the extended state and trigger the indicating structure to protrude from the surface of the electrocoagulation pen body, thereby reminding the doctor to cool down the knife head in time. Therefore, during the electrocision operation on the hypertrophic tonsils and adenoids of children, it can effectively avoid the situation that the knife head overheats during the long-term continuous operation and burns the tissue of the affected area of the child, improve the safety of the soft tissue cutting operation for children, and is also conducive to the recovery and healing of the surgical site of children after the operation.

[0033] 2. During the process that the action structure changes to the extended state and triggers the indicating structure to protrude from the surface of the electrocoagulation pen body to remind the doctor, the extended action structure drives the movable elastic piece to move, so that the distance between the movable elastic piece and the output end of the strip-shaped resistor body continuously increases, and the resistance value also increases accordingly. Therefore, when the present application performs an electrocision operation on the soft tissue of a child and detects that the knife head overheats, it can actively reduce the current passing through the knife head, realize the active cooling treatment of the overheated knife head, and avoid the situation that the overheated knife head burns the tissue of the affected area of the child.

[0034] 3. Insert the soft catheter at the joint of the normal saline infusion tube. After the normal saline flows into the internal part of the columnar liquid collecting tank through the soft catheter, it flows out through the fine liquid holes on the catheter path arranged parallel to the knife head, so that the normal saline can accurately drip on the surface of the knife head performing the electrocision operation, which helps to reduce the risk of overheating of the knife head during the operation, improve the safety of the operation, and continuously and accurately transport the normal saline to the knife head through the catheter path during the electrocision process. The normal saline can lubricate the knife head and avoid the adhesion of the bleeding tissue and the knife head, thus ensuring the smooth progress of the operation.

[0035] 4. During the process that the action structure changes from the retracted state to the extended state, the extended action structure will further drive the conical plugging part to move towards the columnar liquid collecting tank, so that the distance between the conical plugging part and the inner wall of the conical closing groove continuously increases, which can accelerate the flow rate of the normal saline flowing towards the overheated knife head. When the action structure senses that the temperature at the knife head exceeds its preset temperature upper limit, it can cooperate with two active adjustment methods, namely, actively adjusting the dripping speed of the normal saline and actively reducing the current passing through the knife head, to jointly cool down the overheated knife head, so that the heat at the knife head can be quickly dissipated, realizing rapid cooling, and thus more effectively protecting the tissue of the surgical site of children from heat damage, ensuring the safety and success rate of the soft tissue cutting operation for children.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0053] Referring to Figures 1 to 5 , an embodiment of the present application provides a high-frequency soft tissue welding device, including an electrocautery pen body 101, an insulating rod 102 connected to the electrocautery pen body 101, a knife head 103 connected to the insulating rod 102. An electrocutting button and an electrocoagulation button are respectively arranged on the electrocautery pen body 101. A control circuit board is installed inside the electrocautery pen body 101. The electrocutting button and the electrocoagulation button are both electrically connected to the control circuit board. A circuit for supplying power to the knife head 103 is arranged on the control circuit board. When people press the electrocutting button, after the control circuit board receives the electrocutting signal, it will then adjust the output parameters of the high-frequency current supplied to the knife head 103 to meet the requirements of the electrocutting mode. The adjusted current is then supplied to the knife head 103 through the circuit connected to the control circuit board. Similarly, when people press the electrocoagulation button, after the control circuit board receives the electrocoagulation signal, it will adjust the output parameters of the high-frequency current supplied to the knife head 103 to meet the requirements of the electrocoagulation mode. The adjusted current is then supplied to the knife head 103 through the circuit connected to the control circuit board;

[0054] The insulating rod 102 is also provided with a catheter pipeline 105 arranged in parallel with the knife head 103. The catheter pipeline 105 is arranged inside the wall thickness of the insulating rod 102, and one end of the catheter pipeline 105 far from the electrocoagulation pen body 101 extends out from the end of the insulating rod 102;

[0055] A row of fine liquid holes with the outlet direction towards the knife head 103 are opened at the bottom of the catheter pipeline 105. One end of the inner cavity of the catheter pipeline 105 close to the electrocoagulation pen body 101 is also provided with a columnar liquid collecting groove 106 and a conical closing groove 107. The inner cavity of the catheter pipeline 105 is connected to the columnar liquid collecting groove 106 through the conical closing groove 107. The columnar liquid collecting groove 106 is of a cylindrical structure, and the inner cavity of the catheter pipeline 105 is also of a cylindrical structure. And the inner diameter of the columnar liquid collecting groove 106 is larger than the inner diameter of the inner cavity of the catheter pipeline 105;

[0056] The side wall of the catheter pipeline 105 is also connected with a flexible catheter 104 communicated with the columnar liquid collecting groove 106. One end of the flexible catheter 104 far from the catheter pipeline 105 penetrates through the side wall of the insulating rod 102;

[0057] A temperature sensing unit is arranged at the position corresponding to the inner cavity of the electrocoagulation pen body 101 and the catheter pipeline 105. The temperature sensing unit includes a schematic structure and a telescopic action structure. A heat guiding structure and a synchronous component are respectively arranged on the action structure. The synchronous component includes a synchronous rod 211. The synchronous rod 211 respectively penetrates through the heat preservation cylinder seat 205, the electrocoagulation pen body 101, the insulating rod 102, and then hermetically penetrates through the end of the catheter pipeline 105 and extends into the inner cavity of the conical closing groove 107. And a conical plugging part 212 is arranged at one end of the synchronous rod 211 located in the inner cavity of the conical closing groove 107;

[0058] When the action structure changes from the initial retracted state to the extended state, the action structure drives the conical plugging part 212 to move towards the direction of the columnar liquid collecting groove 106.

[0059] The electrocuting temperature at the knife head 103 can be sensed in real time through the action structure in the temperature sensing unit. And when the knife head 103 overheats, 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 knife head 103 in time. Thus, during the electrocision operation on the hypertrophied tonsils and adenoids of children, the situation that the knife head 103 overheats during the long-term continuous operation of the operation and burns the tissue at the affected part of the child can be effectively avoided, the safety of the soft tissue cutting operation for children is improved, and it is also beneficial to the recovery and healing of the operation site of children after the operation.

[0060] Insert the soft catheter 104 into the joint of the infusion tube of the normal saline infusion bottle. After the normal saline flows into the internal part of the columnar liquid collecting tank 106 through the soft catheter 104, it flows out from the fine liquid holes on the catheterization pipeline 105 arranged parallel to the knife head part 103, so that the normal saline can accurately drip on the surface of the knife head part 103 performing the electrocision operation, which helps to reduce the risk of overheating of the knife head part 103 during the operation, improve the safety of the operation, and continuously convey the normal saline to the precise position of the knife head part 103 through the catheterization pipeline 105 during the electrocision process. The normal saline can lubricate the knife head part 103 and avoid the adhesion of the bleeding tissue and the knife head, so as to ensure the smooth progress of the surgical operation.

[0061] Refer to Figure 4 、 Figure 6 、 Figure 7 、 Figures 9 to 11 In this regard, the embodiment of the present application provides a high-frequency soft tissue welding device, and the moving structure includes a heat preservation cylinder seat 205 connected to the inner cavity of the electrocoagulation pen main body 101;

[0062] The inner cavity of the heat preservation cylinder seat 205 is filled with a thermosensitive medium part 210, and the thermosensitive medium part 210 is temperature-sensitive paraffin. The heat preservation cylinder seat 205 is made of heat preservation material. Under the heat preservation and heat insulation effect of the heat preservation cylinder seat 205, the heat transfer between the thermosensitive medium part 210 and the outside can be greatly reduced;

[0063] An insulating passive seat 206 is horizontally slidably inserted into the opening at the end of the heat preservation cylinder seat 205. One end of the synchronous rod 211 far from the conical plug part 212 seals through the end of the heat preservation cylinder seat 205 and extends into the internal part of the thermosensitive medium part 210 and is connected to the insulating passive seat 206;

[0064] A chamfer transition part 214 is provided at the end of the insulating passive seat 206;

[0065] An inward recessed groove 216 is provided on the chamfer transition part 214, and a movable elastic piece 215 is connected in the inner cavity of the inward recessed groove 216;

[0066] Elastic members are provided on both the front and rear sides of the insulating passive seat 206.

[0067] Refer to Figure 10 In this regard, the embodiment of the present application provides a high-frequency soft tissue welding device. The elastic member includes a first side connection seat, and a first return spring 219 is connected to the first side connection seat;

[0068] Two first side connection seats are respectively connected to the front and rear sides of the insulating passive seat 206;

[0069] One end of the first return spring 219 far from the first side connection seat is connected to the inner cavity side wall of the electrocoagulation pen main body 101.

[0070] Refer to Figures 4 to 7, embodiments of the present application provide a high-frequency soft tissue welding device. The heat guiding structure includes a heat insulation sleeve 203. The heat insulation sleeve 203 is disposed inside the wall thickness of the insulating rod 102, and one end of the heat insulation sleeve 203 close to the electrocoagulation pen body 101 passes through the electrocoagulation pen body 101 and the heat insulation cylinder base 205 respectively;

[0071] A heat conducting wire 204 is provided in the inner cavity of the heat insulation sleeve 203. The heat insulation sleeve 203 is made of heat insulation material. Under the heat insulation effect of the heat insulation sleeve 203, the heat transfer between the heat conducting wire 204 and the outside during heat conduction can be greatly reduced;

[0072] Both ends of the heat conducting wire 204 extend out from both ends of the heat insulation sleeve 203. One end of the heat conducting wire 204 is connected with an annular heat conducting net 209, and the other end is sleeved with a heat insulation sleeve 220. The end of the heat insulation sleeve 220 is connected with the end of the heat insulation sleeve 203. The heat insulation sleeve 220 is made of heat insulation material;

[0073] The annular heat conducting net 209 is disposed in the inner cavity of the heat insulation cylinder base 205 and is annularly arranged around the outer circumference of the synchronous rod 211;

[0074] One end of the heat insulation sleeve 220 away from the heat insulation sleeve 203 extends into the knife head part 103. One end of the heat conducting wire 204 away from the heat insulation sleeve 220 passes through the end of the heat insulation cylinder base 205 and extends into the thermosensitive medium part 210 and is connected with the corresponding annular heat conducting net 209.

[0075] Through the annular heat conducting net 209 connected to the end of the heat conducting wire 204, when the heat is conducted to the thermosensitive medium part 210 through the heat conducting wire 204 in the heat guiding structure, due to the relatively larger surface area of the annular heat conducting net 209, it can contact the thermosensitive medium part 210 more fully, so as to realize the uniform distribution of heat. This helps to avoid the uneven heating of the thermosensitive medium part 210 and improve the uniformity and efficiency of heat transfer.

[0076] Refer to Figure 4 , Figure 6 , Figures 9 to 11 , embodiments of the present application provide a high-frequency soft tissue welding device. The schematic structure includes an insulating lifting seat 201. A runner groove is provided at the bottom of the insulating lifting seat 201. A plurality of row-arranged rotating wheels 208 are evenly rotatably connected in the runner groove. Both the insulating lifting seat 201 and the insulating passive seat 206 are made of insulating material;

[0077] The bottom of the insulating lifting seat 201 is also connected with a strip-shaped resistor body 207 that cooperates with the movable elastic piece 215. The free end of the movable elastic piece 215 is closely attached to the bottom surface of the strip-shaped resistor body 207. The output end of the strip-shaped resistor body 207 and the movable elastic piece 215 are both electrically connected to the circuit that supplies power to the knife head part 103 in the electrocoagulation pen body 101;

[0078] On both the left and right sides of the insulating lifting seat 201, there are second side connectors connected, and each second side connector is connected with a second return spring 218;

[0079] At the top of the electrocoagulation pen body 101, there is a reserved opening adapted to the insulating lifting seat 201, and the insulating lifting seat 201 is slidably inserted up and down into the reserved opening;

[0080] One end of the second return spring 218 away from the second side connector is connected to the end of the inner cavity of the electrocoagulation pen body 101.

[0081] When the device is operating, the high temperature at the knife head 103 continuously conducts to the thermosensitive medium part 210 of the action structure through the heat insulation sleeve 220 in the heat conduction structure. When the knife head 103 becomes overheated due to reasons such as a long continuous operation time during the operation, the temperature of the end of the heat conduction wire 204 and the annular heat conduction net 209 located inside the thermosensitive medium part 210 in the heat conduction structure exceeds the phase change temperature of the thermosensitive medium part 210. The thermosensitive medium part 210 that has undergone a phase change expands in volume and drives the insulating passive seat 206 to protrude from the opening at the end of the heat preservation cylinder seat 205. When the chamfer transition part 214 contacts the rotating wheel 208 in the schematic structure, the schematic 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 that the schematic structure protrudes from the surface of the electrocoagulation pen body 101 during the operation, he can quickly judge that the knife head 103 is overheated at this time and needs to cool down the overheated knife head 103 in time. In this way, the action structure in the present application can sense the electrocision temperature at the knife head 103 in real time, and when the knife head 103 becomes 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 knife head 103 in time.

[0082] During the process that the action structure changes to the 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 elastic piece 215 to move, so that the distance between the movable elastic piece 215 and the output end of the strip-shaped resistor body 207 continuously increases, and the resistance value also increases accordingly. Thus, when the present application performs an electrocision operation on the soft tissue of children and monitors that the knife head 103 is overheated, it can actively reduce the current passing through the knife head 103, realize the active cooling treatment of the overheated knife head 103, and avoid the situation that the overheated knife head burns the tissue of the child's affected area.

[0083] During the process of the movement structure changing from the retracted state to the extended state, the extended movement structure will further drive the conical plugging portion 212 to move towards the direction of the columnar liquid collecting groove 106, so that the distance between the conical plugging portion 212 and the inner wall of the conical closing groove 107 continuously increases, which can accelerate the flow rate of the physiological saline flowing towards the overheated cutter head 103. When the movement structure senses that the temperature at the cutter head 103 exceeds its preset temperature upper limit, it can cooperate with each other through two active adjustment methods: actively increasing the dripping speed of the physiological saline and actively reducing the current passing through the cutter head 103, and jointly perform cooling treatment on the overheated cutter head 103, so that the heat at the cutter head can be quickly dissipated, achieving rapid cooling, and thus more effectively protecting the tissues at the pediatric surgical site from thermal damage, and ensuring the safety and success rate of pediatric soft tissue cutting surgery.

[0084] 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 them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
