Description

Technical Field

[0001] This utility model relates to a cutting electrode, and more particularly to a uvula cutting electrode tip, belonging to the field of medical device technology. Background Technology

[0002] An elongated uvula is related to genetic factors, chronic inflammation, local trauma, and nasopharyngeal diseases. An elongated uvula can cause throat discomfort, nausea and vomiting, and in severe cases, it can affect breathing and sleep. Therefore, an elongated uvula requires surgical treatment.

[0003] Currently, uvuloplasty is mainly performed under general or local anesthesia, using a scalpel for removal. Although the surgery is relatively simple, it involves significant bleeding and a slow recovery.

[0004] Laser excision surgery mainly uses the high-temperature energy of laser light to remove the uvula. It has the advantages of less intraoperative bleeding and clear vision. However, if the laser excision surgery is not performed properly, it may cause thermal damage to the surrounding tissues.

[0005] High-frequency electrosurgical units can achieve both rapid cutting and rapid ablation. Currently, the application of high-frequency electrosurgical units in surgery is very mature, and there are various types of electrode tips. However, there is no electrode tip that can be used to cut the uvula. Utility Model Content

[0006] The purpose of this invention is to provide a uvula cutting electrode tip to solve the technical problems in the prior art. It can be connected to a high-frequency electrosurgical unit to achieve rapid uvula removal, with the advantages of less bleeding and faster recovery.

[0007] This utility model provides a uvula cutting electrode tip, including an electrode core rod, one end of which has a connecting rod, and the other end of which is equipped with an electrode frame, on which an electrode wire is fixed.

[0008] In the aforementioned uvular cutting electrode head, preferably, the connecting rod and the electrode core rod are integrally machined.

[0009] In the aforementioned uvular cutting electrode head, preferably, the diameter of the connecting rod 2 is 1.4mm-1.8mm, and the diameter of the electrode core rod is 2.2mm-2.8mm.

[0010] In the aforementioned uvular cutting electrode head, preferably, the end of the electrode core rod connected to the electrode frame has a mounting hole, and the electrode frame is fixedly connected after being inserted into the mounting hole.

[0011] In the aforementioned uvula cutting electrode tip, preferably, the electrode frame includes a first L-shaped tube and a second L-shaped tube. The first L-shaped tube is composed of a first connecting section and a first supporting section, and the second L-shaped tube is composed of a second connecting section and a second supporting section. The first connecting section is fully inserted into the mounting hole, the first supporting section is perpendicular to the first connecting section, a portion of the second connecting section is inserted into the mounting hole, the second supporting section is perpendicular to the second connecting section, and the second supporting section is parallel to the first supporting section.

[0012] In the aforementioned uvular cutting electrode head, preferably, the electrode wire is a tungsten wire, and the two ends of the electrode wire are respectively inserted and fixedly connected to the first support section and the second support section, and the electrode wire is parallel to the second connecting section.

[0013] In the aforementioned uvular cutting electrode head, preferably, a first heat shrink tube is sleeved on the first L-shaped tube, and a second heat shrink tube is sleeved on the second L-shaped tube.

[0014] In the aforementioned uvular cutting electrode tip, preferably, the length of the first heat shrink tube is the same as the length of the first L-shaped tube, the length of the second heat shrink tube is greater than the length of the second L-shaped tube, and one end of the second heat shrink tube extends 2mm-4mm beyond the end of the second support section.

[0015] In the aforementioned uvular cutting electrode head, preferably, the electrode core rod, the first heat shrink tubing, and the second heat shrink tubing are coated with an insulating powder coating layer.

[0016] Compared with existing technologies, this invention connects to the high-frequency electrosurgical unit via a connecting rod at the end of the electrode core. The high-frequency electrosurgical unit transmits high-frequency radio frequency waves to the electrode wire through the connecting rod, electrode core, and electrode frame. When the electrode wire contacts the uvula, the high-frequency radio frequency waves strike the uvula, causing water molecules in the tissue cells to oscillate upon receiving the radio frequency waves. This oscillation of the water molecules leads to vaporization, causing the cells to rupture and achieving the effects of cutting, hemostasis, and ablation. This invention has a simple structure, is easy to operate, and can achieve rapid cutting of the uvula, hemostasis, and ablation. Attached Figure Description

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] Embodiments of this utility model: such as Figures 1-4 As shown, a uvula cutting electrode head includes an electrode core rod 1, one end of which has a connecting rod 2, and the other end of which is equipped with an electrode frame 3, on which an electrode wire 4 is fixed.

[0024] Both the electrode core rod 1 and the connecting rod 2 are metal round rods, preferably made of stainless steel 304 (06Cr19Ni10) or other metals with good conductivity such as stainless steel 316 or nickel-titanium alloy. The connecting rod 2 and the electrode core rod 1 are integrally machined, and the diameter of the connecting rod 2 is smaller than the diameter of the electrode core rod 1. The motor frame 3 is made of metal, preferably the same material as the electrode core rod 1.

[0025] The diameter of the connecting rod 2 is 1.4mm-1.8mm, preferably 1.6mm in this embodiment, and the length of the connecting rod 2 is 15mm-20mm, preferably 17mm; the diameter of the electrode core rod 1 is 2.2mm-2.8mm, preferably 2.5mm in this embodiment, and the length of the electrode core rod 1 is 60mm-80mm, preferably 70mm.

[0026] The electrode core rod 1 has a mounting hole 5 at one end where it connects to the electrode frame 3. The electrode frame 3 is then inserted into the mounting hole 5 and fixedly connected. The fixing method can be welding, or the electrode frame 3 can be clamped by flattening the mounting hole 5 at the end of the electrode core rod 1 after insertion.

[0027] Furthermore, the electrode frame 3 includes a first L-shaped tube and a second L-shaped tube. The first L-shaped tube is composed of a first connecting section 6 and a first supporting section 7. The second L-shaped tube is composed of a second connecting section 8 and a second supporting section 9. The first connecting section 6 is fully inserted into the mounting hole 5. The first supporting section 7 is perpendicular to the first connecting section 6. A portion of the second connecting section 8 is inserted into the mounting hole 5, and the other portion is located outside the mounting hole 5. The second supporting section 9 is perpendicular to the second connecting section 8 and parallel to the first supporting section 7.

[0028] The electrode frame 3 and the electrode core rod 1 are combined in a roughly "flag" shape. This shape of electrode makes it easy to insert into the patient's mouth, and the electrode wire 4 is located on the side, so it can be clearly observed when cutting the uvula.

[0029] This embodiment provides a preferred embodiment of the electrode frame 3. The length of the second connecting segment 8 outside the mounting hole 5 is preferably 13 mm. The lengths of the first support segment 7 and the second support segment 9 are both preferably 10.5 mm. The outer diameters of the first connecting segment 6, the first support segment 7, the second connecting segment 8, and the second support segment 9 are all preferably 1.5 mm, and the inner diameters are all preferably 0.2 mm. The diameter of the electrode wire 4 is preferably 0.2 mm. It should be noted that this is only a preferred embodiment, and the dimensions of the electrode frame 3 and the electrode wire 4 can be adjusted according to actual needs.

[0030] The electrode wire 4 is a tungsten wire. The two ends of the electrode wire 4 are inserted into and fixedly connected to the first support section 7 and the second support section 9, respectively. The electrode wire 4 is parallel to the second connecting section 8.

[0031] Furthermore, a first heat-shrink tubing 10 is fitted onto the first L-shaped tube, and a second heat-shrink tubing 11 is fitted onto the second L-shaped tube. The length of the first heat-shrink tubing 10 is the same as the length of the first L-shaped tube, and the length of the second heat-shrink tubing 11 is greater than the length of the second L-shaped tube. One end of the second heat-shrink tubing 11 extends 2mm-4mm, preferably 2.5mm, beyond the end of the second support section 9. This structural design allows for better protection of the tissues surrounding the uvula during actual use, preventing damage to surrounding tissues due to misoperation.

[0032] Since the second heat shrink tubing 11 extends beyond the second support section 9, a notch needs to be provided on the second heat shrink tubing 11 to allow the electrode wire 4 to pass through. The first heat shrink tubing 10 and the second heat shrink tubing 11 serve two purposes: firstly, they provide insulation to effectively prevent current leakage; secondly, they prevent burns caused by excessive heat.

[0033] Furthermore, such as Figure 4 As shown, the electrode core rod 1, the first heat shrink tube 10 and the second heat shrink tube 11 are coated with an insulating powder coating layer 12.

[0034] The working principle of this utility model is as follows: When in use, the connecting rod 2 is plugged into the high-frequency electrosurgical unit. The high-frequency electrosurgical unit is an existing technology product that can be purchased directly. For example, the model that can be used is: Donghong Zhiyuan High-Frequency Surgical Equipment HFS60 / 80 / 120.

[0035] During the surgery, the high-frequency electrosurgical unit is activated. The high-frequency electrosurgical unit transmits high-frequency radio frequency waves to the electrode wire 4 through the connecting rod 2, electrode core rod 1, first L-shaped tube and second L-shaped tube. When the electrode wire 4 comes into contact with the uvula, the high-frequency radio frequency waves hit the uvula, causing the water molecules in the cells of the tissue to receive the radio frequency waves and oscillate. The oscillation of the water molecules produces a vaporization effect, causing the cells to rupture and achieve the effects of cutting, hemostasis and ablation.

[0036] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
