[0003] Therefore, existing technologies still need to be improved. Utility Model Content

[0004] The purpose of this application is to provide an electrocoagulation hemostatic pen for the nasal cavity, in order to solve the problem that the heating element of current bipolar electrocoagulation or electrode electrocoagulation has a small range, which cannot cover the area around the bleeding point in one go, and often requires multiple electrocoagulations, thereby increasing the patient's pain.

[0005] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0006] An electrocoagulation pen for use in the nasal cavity, comprising:

[0007] The main body is in the shape of a pen, with a pen tip;

[0008] An electrocoagulation head is disposed on the tip of the pen. The electrocoagulation head includes a first electrode tube, a second electrode tube, and a heating element. The second electrode tube is disposed on one side of the first electrode tube. The two ends of the heating element are respectively connected to the first electrode tube and the second electrode tube. The heating element is configured as a ring-shaped heating element. The width of the middle part of the heating element is greater than the distance between the first electrode tube and the second electrode tube.

[0009] The liquid aspiration assembly includes a liquid aspiration conduit, one end of which is disposed inside the pen-shaped body and the other end extends out to the outside of the pen tip and is located within the ring-shaped area of ​​the heating element. The liquid aspiration assembly is used to aspirate blood accumulated around the bleeding point.

[0032] Nasal bleeding is one of the most common emergencies in ENT (Ear, Nose, and Throat) surgery. Mild cases may only present with blood-tinged nasal discharge, while severe cases can lead to hemorrhagic shock. Due to the complexity of its causes, there are many diagnostic and treatment methods for nasal bleeding. Electrocoagulation is suitable for patients with a clearly identifiable bleeding point. Compared to traditional methods such as nasal packing, electrocoagulation has advantages such as relatively simple operation, rapid hemostasis, and less damage to surrounding tissues. However, it also has the following drawbacks:

[0033] First, conventional electrocoagulation units are large and heavy, making them inconvenient to move and lacking portability, thus prolonging treatment time and failing to meet the needs of emergency and outpatient consultation scenarios. Second, in cases of severe bleeding, directly cauterizing the bleeding point is difficult due to the presence of flowing blood, and continuous cauterization can lead to excessive damage to local tissues. Therefore, guidelines for nasal bleeding recommend cauterizing the area around the bleeding point first, and then sealing the severed blood vessel ends after the bleeding stops or the blood flow slows down. However, current bipolar or electrode electrocoagulation devices have a relatively small heating element area; the maximum width of the heating element is often less than the distance between the two electrode tubes. This makes it impossible to cover the area around the bleeding point in one go, often requiring multiple electrocoagulation sessions, which increases patient discomfort.

[0034] For this purpose, please refer to Figure 1 , Figure 2 and Figure 3 This application provides an electrocoagulation hemostatic pen for the nasal cavity, comprising a pen-shaped body 1, an electrocoagulation head 2, and a liquid aspiration assembly 3. The pen-shaped body 1 has a pen tip end 11, and the electrocoagulation head 2 is disposed on the pen tip end 11. The electrocoagulation head 2 includes a first electrode tube 21, a second electrode tube 22, and a heating element 23. The second electrode tube 22 is disposed on one side of the first electrode tube 21. The two ends of the heating element 23 are respectively connected to the first electrode tube 21 and the second electrode tube 22. The heating element 23 is configured as a ring-shaped heating element, and the width of the middle part of the heating element 23 is greater than the distance between the first electrode tube 21 and the second electrode tube 22. The liquid aspiration assembly 3 includes a liquid aspiration conduit 31, one end of which is disposed inside the pen-shaped body 1, and the other end extends out to the outside of the pen tip end 11 and is located within the ring-shaped area of ​​the heating element 23. The liquid aspiration assembly 3 is used to aspirate the blood accumulated around the bleeding point.

[0035] Wherein, the end of the heating element 23 that is close to the first electrode tube 21 or the second electrode tube 22 is defined as the first end, and the end of the heating element that is away from the first electrode tube 21 or the second electrode tube 22 is defined as the second end. The middle part of the heating element 23 is the middle end between the first end and the second end. The width of the middle part of the heating element 23 refers to the distance between the two sides of the middle end of the heating element 23.

[0036] The electrocoagulation hemostasis pen of this embodiment is easy to carry. By setting the heating element 23 of the electrocoagulation head 2 in the electrocoagulation hemostasis pen as a ring-shaped heating element 23, and setting the width of the middle part of the heating element 23 to be greater than the distance between the first electrode tube 21 and the second electrode tube 22, the area covered around the bleeding point can be expanded, so as to achieve simultaneous electrocoagulation hemostasis around the bleeding point, thereby reducing the number of repeated electrocoagulations. At the same time as electrocoagulation, combined with the suction component 3, the blood around the bleeding point can be sucked into the suction component 3, thereby timely removing the surface blood and improving the efficiency of electrocoagulation hemostasis.

[0037] Optionally, in one embodiment, the pen-shaped body 1 is configured as a polycarbonate body, wherein the polycarbonate is of medical grade.

[0038] Optionally, in one embodiment, the length of the pen tip 11 is set to 10-12 cm. Within this range, the electrocoagulation head 2 of the electrocoagulation pen can completely detect the innermost part of the nasal cavity, which meets the length requirements for electrocoagulation hemostasis of nasal bleeding.

[0039] Optional, see below Figure 1 and Figure 2 In one embodiment, the heating element 23 is a tungsten alloy heating element 23, wherein the heating element 23 is inclined relative to a vertical plane, wherein the vertical plane is parallel to the line connecting the first electrode tube 21 and the second electrode tube 22 and overlaps the central axis surface of the pen-shaped body 1. In this embodiment, by inclining the heating element 23 relative to the vertical plane, the pen-shaped body 1 or the electrocoagulation head 2 can be prevented from blocking the operator's line of sight. Correspondingly, in order to enable the suction conduit 31 of the suction assembly 3 to better suction the blood accumulation around the bleeding point, the end of the suction conduit 31 located inside the heating element 23 is inclined relative to the vertical plane.

[0040] Optional, see below Figure 1 and Figure 2 In one embodiment, the angle between the heating element 23 and the vertical plane is set to 25-35°, and the angle between the end of the suction conduit 31 located inside the heating element 23 and the vertical plane is also set to 25-35°. Specifically, when the angle between the heating element 23 and the vertical plane is set to 25°, the angle between the end of the suction conduit 31 located inside the heating element 23 and the vertical plane is also set to 25°; when the angle between the heating element 23 and the vertical plane is set to 35°, the angle between the end of the suction conduit 31 located inside the heating element 23 and the vertical plane is also set to 35°. This embodiment achieves a better field of vision by setting both angles within this range, without affecting the operator's work.

[0041] Optionally, in one embodiment, the aspiration catheter 31 may be configured as a polymer catheter.

[0042] Optional, see below Figure 1 and Figure 3In one embodiment, the suction assembly 3 further includes a negative pressure aspirator 32 and a reservoir tube 33. The negative pressure aspirator 32 is disposed inside the pen-shaped body 1 and connected to the suction conduit 31. The reservoir tube 33 is disposed inside the pen-shaped body 1 and connected to the negative pressure aspirator 32. The negative pressure aspirator 32 draws the blood around the nasal bleeding point into the reservoir tube 33 through the suction conduit 31, thereby clearing the blood around the nasal bleeding point and improving the efficiency of electrocoagulation hemostasis.

[0043] Optionally, in one embodiment, the volume of the reservoir tube 33 can be set to 15ml, and the reservoir tube 33 and the negative pressure aspirator 32 are detachably connected. In this embodiment, by making the reservoir tube 33 and the negative pressure aspirator 32 detachably connected, after the electrocoagulation hemostatic pen is used up, the reservoir tube 33 can be removed to facilitate the cleaning of the blood in the reservoir tube 33, and also facilitates the next use.

[0044] The liquid storage tube 33 and the negative pressure suction device 32 can be configured to be threadedly connected. The liquid storage tube 33 has an installation groove with an internal thread. The negative pressure suction device 32 has an external thread that matches the internal thread at one end near the liquid storage tube 33. The internal thread is connected to the external thread to realize the threaded connection between the liquid storage tube and the negative pressure suction device 32.

[0045] Optional, see below Figure 3 In one embodiment, an operating handle 4 is provided at the end of the liquid storage tube 33 away from the negative pressure aspirator 32. In this embodiment, the operating handle 4 is provided to facilitate the removal of the liquid storage tube 33 from the negative pressure aspirator 32.

[0046] Optional, see below Figure 3 In one embodiment, the operating handle 4 can be configured as a T-shaped handle.

[0047] Optionally, in one embodiment, the electrocoagulation hemostasis pen further includes an illumination module (not shown in the figure). The illumination module can be disposed on the end face of the pen tip 11. In this embodiment, by providing an illumination module, illumination services can be provided for the operator when performing electrocoagulation hemostasis, thereby improving the efficiency of electrocoagulation hemostasis.

[0048] Optional, see below Figure 3In one embodiment, the pen-shaped body 1 has a power supply cavity 12. The electrocoagulation hemostatic pen also includes a power module 5. The power module 5 is disposed in the power supply cavity 12 and is electrically connected to the heating element 23, the negative pressure suction device 32 and the lighting module. In this embodiment, by providing the power module 5, power can be provided for the operation of the heating element 23, the negative pressure suction device 32 and the lighting module.

[0049] Optional, see below Figure 1 In one embodiment, the electrocoagulation hemostatic pen further includes a switch module 6, which is disposed on the outer side of the pen-shaped body 1 and connected to the power module 5. In this embodiment, the switch module 6 is used to control the electrocoagulation hemostasis operation of the heating element 23, the liquid suction operation of the negative pressure aspirator 32, and the illumination operation of the illumination module. It is foreseeable that when the switch module 6 is turned on, the heating element 23, the negative pressure aspirator 32, and the illumination module simultaneously operate; when the switch module 6 is turned off, the heating element 23, the negative pressure aspirator 32, and the illumination module simultaneously stop operating.

[0050] Optionally, in one embodiment, the power module 5 may be configured as a lithium battery pack.

[0051] Optional, see below Figure 1 , Figure 2 and Figure 3 In one embodiment, the pen-shaped body 1 is provided with an anti-slip textured layer 7 on the outer side near the switch module 6. The anti-slip textured layer 7 is located in the grip area. By providing the anti-slip textured layer 7, this embodiment can play an anti-slip role, thereby ensuring the operational stability of the operator when operating the electrocoagulation hemostatic pen of this embodiment.

[0052] In summary, this application provides an electrocoagulation hemostatic pen for the nasal cavity, comprising a pen-shaped body 1, an electrocoagulation head 2, and a suction assembly 3. The pen-shaped body 1 has a pen tip end 11, and the electrocoagulation head 2 is disposed on the pen tip end 11. The electrocoagulation head 2 includes a first electrode tube 21, a second electrode tube 22, and a heating element 23. The second electrode tube 22 is disposed on one side of the first electrode tube 21. The two ends of the heating element 23 are respectively connected to the first electrode tube 21 and the second electrode tube 22. The heating element 23 is configured as a ring-shaped heating element, and the width of the middle part of the heating element 23 is greater than the distance between the first electrode tube 21 and the second electrode tube 22.
