Description

Technical Field

[0001] The present invention relates to the technical field of high-frequency surgical energy platforms, and in particular to a soft tissue high-frequency welding terminal. Background Art

[0002] The Soft Tissue High-Frequency Welding Terminal is a specialized device used for welding and sealing soft tissue during medical procedures. It utilizes the thermal effects of high-frequency current to achieve tissue cutting, hemostasis, and welding. It is primarily used in surgery, minimally invasive procedures, and tissue repair. It eliminates the need for traditional suture materials (such as sutures or staples). The heat generated by the high-frequency current denatures and coagulates the protein molecules in the soft tissue, achieving tissue connection, hemostasis, and promoting healing.

[0003] Patent publication number CN108523988A discloses a high-frequency electrosurgical treatment device, which mainly includes an electrosurgical probe, an electrosurgical handle, a conductive fluid, a suction device, and a control host. The electrosurgical probe is mainly composed of an electrode terminal, an insulating insert, a joint, a support component, a connector, and a shell. The high-frequency electrosurgical treatment device of the present invention not only has improvements on the head, making the individual cutting surface smaller and the total cutting surface relatively large, thereby ensuring cutting safety and cutting efficiency, but also has a suction device that can absorb the residue generated after cutting, ensuring the cleanliness and smoothness of the cutting surface and improving the cutting effect; the blade head is also provided with an illumination light source and a camera, and pictures and video materials are displayed through the image display screen of the control host, allowing for more intuitive observation of the cutting surface, and various operations can be controlled through the control host.

[0004] The existing technology has the following defects:

[0005] Electrode clogging or adhesion is a common problem, primarily manifested by tissue, blood, or other substances adhering to the electrode tip, which reduces conductivity and affects surgical outcomes. The following is a more in-depth analysis and explanation:

[0006] 1. Cause Analysis

[0007] The formation mechanism of electrode clogging or adhesion is usually related to the following factors:

[0008] Tissue fragments: When the electrode tip contacts the myocardium, it may cause mechanical damage to the tissue, leading to adhesion of tissue fragments.

[0009] Blood clot: During surgery, the local temperature rises (such as during radiofrequency ablation), which can easily activate the coagulation process and form blood clots that adhere to the electrode surface.

[0010] Protein deposition: Proteins in plasma (such as fibrinogen) easily coagulate under high temperature conditions to form an adhesion layer.

[0011] Electrode material problem: Some low-quality electrode materials have rough surfaces and are prone to absorbing foreign matter or tissue residue.

[0012] Inflammatory response: Radiofrequency energy release causes local myocardial tissue inflammation, triggering fibrin deposition or platelet aggregation.

[0013] 2. Impact on surgery

[0014] Reduced efficiency of radiofrequency ablation: Obstruction of current conduction will result in ineffective delivery of energy to the target tissue.

[0015] Poor ablation results may lead to multiple ablations, prolonged operation time and even complications.

[0016] Interruption of surgery:

[0017] If the blockage is severe, the electrode needs to be cleaned or replaced, which may force the surgery to be suspended, prolong the operation time and increase the risk. Summary of the Invention

[0018] In view of the above problems in the prior art, a soft tissue high-frequency welding terminal is proposed.

[0019] The present application provides a soft tissue high-frequency welding terminal, the purpose of which is to provide a welding terminal that can scrape off the sticky covering on the blade during surgery to ensure the radio frequency effect of the blade.

[0020] The technical solution of the present invention is: a soft tissue high-frequency welding terminal, comprising a gripping handle, a welding head with an electrode disposed in the gripping handle and an electrode disposed at one end of the electrode, the welding head extending out of the gripping handle, and a cleaning unit for scraping the welding head disposed in the gripping handle;

[0021] The cleaning unit includes a cleaning box arranged at the end of the gripping handle, the interior of the cleaning box is hollow and a through hole is provided along the axial direction of the welding head, there is a gap between the through hole and the welding head, a scraper is provided in the gap between the through hole and the welding head, the end of the scraper close to the end of the welding head is a scraper part, the scraper part is in contact with the hole wall of the through hole and the welding head, a scraper cavity is provided in the scraper part, the end of the scraper away from the end of the welding head is a connecting part, one end of the connecting part is connected to the scraper part, and the other end passes through the through hole and extends to the gripping handle Inside the handle, there is a gap between the connecting portion and the through hole, a wedge ring 1 is fixed to the connecting portion near the gripping handle, a wedge ring 2 is slidably provided in the through hole, a limit ring 1 and a limit ring 2 are respectively fixed near the left and right openings of the through hole, the wedge ring 2 slides between the limit ring 1 and the limit ring 2, the wedge ring 1 and the wedge ring 2 are in contact via an inclined surface, a crack is provided on the scraper, the crack divides the scraper into two equal parts, the crack extends into the gripping handle, and the scrapers on the upper and lower sides of the crack have a tendency to separate from each other;

[0022] The cleaning unit includes a transmission assembly connected to the connecting portion and used for controlling the extension and retraction of the scraping member.

[0023] With the above solution, by providing a cleaning unit, the scraper separates into upper and lower parts after extending from the through hole. After wedge ring 1 moves to the first limiting ring and is pressed against wedge ring 2, the upper and lower parts of the scraper close. During the scraper's retraction process, the scraper scrapes away the adhered material on the welding head. After wedge ring 1 moves to the second limiting ring, wedge ring 2 is restrained and disengaged from wedge ring 1, completing one scraping action. This scraping action, in which the scraper first extends and then closes and retracts, removes the adhered material on the welding head into the scraping cavity, preventing the adhered material from falling into the wound surface and becoming difficult to clean. This ensures intraoperative cleanliness while cleaning the welding head.

[0024] Furthermore, the transmission assembly includes a button groove arranged in the gripping handle, an operating button slidably arranged in the button groove, a spring that resists the button groove and the operating button, a connecting ring arranged at the end of the connecting part away from the welding head, a fixing rod arranged on the connecting ring, a spiral pattern arranged on the outer wall of the fixing rod, a rotating column sleeved on the fixing rod, a gear ring arranged on the outer wall of the rotating column, and a rack arranged on the operating button, the rack is engaged with the gear ring, the rotating column is rotatably arranged in the button groove through a pair of bracket plates, and a spiral groove matching the spiral pattern is provided in the rotating column.

[0025] By adopting the above scheme, a transmission component is set up to transmit the action of pressing the operating button downward into the extension action of the scraper, and the operating button is reset by the spring, which is transmitted into the retraction action of the scraper. That is, by pressing the operating button once, the scraper completes an opening and extension, and then closes and retracts the scraping action.

[0026] Furthermore, a pair of drain ports 1 are provided on the scraping portion, and drain ports 2 are provided in the cleaning box at positions corresponding to drain ports 1, and drain ports 1 and 2 are connected to the interior of the cleaning box and the scraping cavity.

[0027] By adopting the above solution, the scraped attachments are collected into the cleaning box through the first and second drainage outlets, thereby increasing the storage space for the attachments.

[0028] Furthermore, a protrusion is provided at the junction of the scraping portion and the connecting portion, and the protrusion abuts against the second edge of the sewage outlet. The side of the protrusion close to the second sewage outlet is an inclined surface, and the side away from the first sewage outlet is an arc surface.

[0029] With the above solution, by providing the convex block, the adhered matter in the scraping cavity can be easily collected into the cleaning box through the inclined surface. At the same time, when the scraping element is retracted, the arc surface can easily retract the scraping element into the through hole.

[0030] Furthermore, the second sewage outlet is provided with a check plate.

[0031] By adopting the above solution, the anti-return plate prevents the adhered matter in the cleaning box from flowing back into the scraping cavity.

[0032] Furthermore, the inclination angle of the contact surface between the wedge ring 1 and the wedge ring 2 is 70°.

[0033] By adopting the above scheme, a large inclination angle is set to increase the contact area between wedge ring 1 and wedge ring 2, and the friction between wedge ring 1 and wedge ring 2 is increased, so that wedge ring 1 and wedge ring 2 are not easy to separate after being squeezed into contact, and can only be separated by limiting ring 2 to block wedge ring 2.

[0034] Furthermore, the contact surface between the scraping portion and the welding head is provided with scraping lines.

[0035] By adopting the above solution, the scraping lines are used to increase the scraping effect of the scraping portion on the attachments on the welding joint.

[0036] Furthermore, the connection between the cleaning box and the gripping handle is a detachable bottom cover, and the bottom cover is provided with pins, and the pins are connected to the gripping handle.

[0037] With the above solution, by providing a detachable cleaning box, the cleaning box can be detached from the gripping handle after the operation, and the bottom cover of the cleaning box can be opened to collect the attachments collected in the cleaning box.

[0038] Beneficial effects of the present invention:

[0039] By providing a cleaning unit, the scraper separates into upper and lower parts after extending from the through hole. Wedge ring 1 moves to the first limiting ring and is squeezed against wedge ring 2. The upper and lower parts of the scraper close together. During the scraper's retraction process, the scraper scrapes away the adhered matter on the welding head. Wedge ring 1 moves to the second limiting ring, where wedge ring 2 is restrained and separated from wedge ring 1, completing one scraping action. This scraping action, in which the scraper first extends and then closes and retracts, removes the adhered matter on the welding head into the scraping cavity, preventing the adhered matter from falling into the wound surface and becoming difficult to clean. This ensures intraoperative cleanliness while cleaning the welding head. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0053] 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 with reference to the accompanying drawings.

[0054] Example, see Figures 1-11, as an embodiment of the present invention, a soft tissue high-frequency welding terminal is provided, comprising a gripping handle 1, an electrode 2 arranged in the gripping handle 1, a welding head 3 arranged at one end of the electrode 2, the welding head 3 extending outside the gripping handle 1, and a cleaning unit for scraping the welding head 3 is also provided in the gripping handle 1; the cleaning unit comprises a cleaning box 4 arranged at the end of the gripping handle 1, the cleaning box 4 is hollow inside and is provided with a through hole 5 along the axial direction of the welding head 3, there is a gap between the through hole 5 and the welding head 3, a scraper 6 is provided in the gap between the through hole 5 and the welding head 3, the end of the scraper 6 close to the end of the welding head 3 is a scraping portion 7, the scraping portion 7 is in contact with the hole wall of the through hole 5 and the welding head 3, a scraping cavity 8 is provided in the scraping portion 7, the end of the scraper 6 away from the end of the welding head 3 is a connecting portion 9, the connecting portion One end of 9 is connected to the scraping part 7, and the other end passes through the through hole 5 and extends into the gripping handle 1. There is a gap between the connecting part 9 and the through hole 5. A wedge ring 10 is fixed to the connecting part 9 near the gripping handle 1, and a wedge ring 2 11 is slidingly arranged in the through hole 5. A limit ring 12 and a limit ring 2 13 are respectively fixed near the left and right openings of the through hole 5. The wedge ring 2 11 slides between the limit ring 12 and the limit ring 2 13. The wedge ring 10 and the wedge ring 2 11 are in contact with each other through an inclined surface. A crack 14 is provided on the scraping member 6. The crack 14 divides the scraping member 6 into two equal parts, the upper and lower parts. The crack 14 extends into the gripping handle 1, and the scraping members 6 on the upper and lower sides of the crack 14 tend to separate from each other; the cleaning unit includes a transmission assembly, which is connected to the connecting part 9 and is used to control the extension and retraction of the scraping member 6.

[0055] In this embodiment, current flows from electrode 2 through welding head 3 and then into the human body, passing through the tissue to the negative electrode plate, forming a closed circuit. The high-frequency current generates heat at the tip of electrode 2, heating the tissue to the point of protein denaturation, thereby achieving cutting, hemostasis, and welding. The welding head 3 is flat to accommodate the requirements of tissue welding. The scraper 6 is made of a non-conductive material. Its upper and lower portions, divided by a slit 14, are always in an open position. Because the scraper portion 7 is sized to fit the through-hole 5, when the scraper portion 7 is retracted into the through-hole 5, the upper and lower portions of the scraper 6 are in a closed position. When the scraper portion 7 extends out of the through-hole 5, the upper and lower portions of the scraper 6 are in an open position. Wedge ring 10 and wedge ring 2 11 are in contact and mating to ensure that the upper and lower portions of the scraper 6 extend in an open position to the end of the welding head 3, and then retract in a closed position.

[0056] When designing the cleaning unit for the soft tissue high-frequency welding terminal, the scraper 6 with upper and lower detachable parts is used, which has the following significant advantages:

[0057] Improved cleaning efficiency: The detachable scraper 6 can dynamically adjust its opening and closing angles during the cleaning process. When extended, it opens to cover a wider area, avoiding direct contact with the welding head 3 when not in use, reducing wear and resistance. It closes after reaching the very end of the welding head 3, precisely clamping and cleaning key areas of the welding head 3 and effectively removing dirt and residue. This design ensures accurate movement of the scraper 6 during operation, providing comprehensive and efficient cleaning of the welding head 3.

[0058] Preventing damage to the welding head 3: The welding head 3 is the core component of the high-frequency surgical energy platform. If the cleaning mechanism remains clamped throughout the cleaning process, it may cause wear or deformation to the welding head 3 surface. By adopting a design that opens when extended, closes for cleaning, and separates when retracted, the scraper 6 only comes into direct contact with the welding head 3 during the necessary stages, reducing damage to the welding head 3 surface material and extending the life of the welding head 3.

[0059] Reducing frictional resistance: When the scraper 6 is extended, unnecessary friction with the welding head 3 or other components is avoided, which can reduce movement resistance and lower the power consumption requirements of the mechanism, thereby improving the stability and reliability of the overall operation.

[0060] Optimized cleaning effect: The closed action design allows the scraper 6 to more precisely adapt to the shape of the welding head 3, especially cleaning critical areas such as the end of the welding head 3. When closed, the scraper 6 can provide sufficient pressure to remove stains, solidified tissue, or other attachments, improving the cleaning effect.

[0061] Convenient for mechanical maintenance: The detachable design of the upper and lower parts makes it easier to disassemble and maintain the scraper 6 when not in operation. If the cleaning mechanism is worn or malfunctions, the damaged scraper 6 parts can be replaced separately without replacing the entire cleaning mechanism, reducing maintenance costs.

[0062] Improved safety: The scraper 6 is closed only when necessary, which greatly reduces the risk of accidental injury to the welding joint 3. It can also prevent the cleaning mechanism from getting stuck or damaged due to misoperation during the retraction process, thereby improving the safety and reliability of the system operation.

[0063] The design of the scraper 6, which can be separated up and down and dynamically adjusted to open and close, can take into account efficient cleaning, protection of the welding head 3, smooth movement and mechanical safety. It is a very reasonable and targeted optimization design idea, which is suitable for precision medical equipment such as soft tissue high-frequency welding terminals that have high requirements for cleaning and maintenance.

[0064] Reference Figure 3 、 Figure 5 、 Figure 6The transmission assembly includes a button groove 15 arranged in the gripping handle 1, an operating button 16 slidably arranged in the button groove 15, a spring 17 that resists the button groove 15 and the operating button 16, a connecting ring 18 arranged at the end of the connecting part 9 away from the welding head 3, a fixing rod 19 arranged on the connecting ring 18, a spiral pattern 20 arranged on the outer wall of the fixing rod 19, a rotating column 21 sleeved on the fixing rod 19, a gear ring 22 arranged on the outer wall of the rotating column 21, and a rack 23 arranged on the operating button 16, the rack 23 is engaged with the gear ring 22, and the rotating column 21 is rotatably arranged in the button groove 15 through a pair of bracket plates 24, and a spiral groove matching the spiral pattern 20 is provided in the rotating column 21.

[0065] In this embodiment, a pair of bracket plates 24 are fixed on the inner wall of the button groove 15, and the rotating column 21 is rotatably set on the pair of bracket plates 24. When in use, the operating button 16 is pressed, and the operating button 16 drives the rack 23 to move. The rack 23 drives the rotating column 21 to rotate by engaging with the ring gear 22. The spiral groove in the rotating column 21 cooperates with the spiral pattern 20 to move the fixed rod 19 toward the welding head 3, driving the scraper 6 to extend.

[0066] By setting up a transmission component, the action of pressing the operating button 16 downward is transmitted to the extension action of the scraper 6, and the operating button 16 is reset by the spring 17, which is transmitted to the retraction action of the scraper 6. That is, when the operating button 16 is pressed once, the scraper 6 completes an opening and extension, and then closes and retracts the scraping action.

[0067] Reference Figure 4 and Figure 8 A pair of drain ports 25 are provided on the scraping portion 7 , and drain ports 2 26 are provided in the cleaning box 4 at positions corresponding to the drain ports 25 . The drain ports 25 and 26 communicate with the interior of the cleaning box 4 and the scraping chamber 8 .

[0068] In this embodiment, the drain port is provided near one end of the welding head 3, and the scraped attachments are collected into the cleaning box 4 through the drain port 1 25 and the drain port 2 26, thereby increasing the storage space for the attachments.

[0069] Reference Figure 4 A protrusion 27 is provided at the junction of the scraping portion 7 and the connecting portion 9, and the protrusion 27 abuts against the edge of the second sewage outlet 26. The side of the protrusion 27 close to the second sewage outlet 26 is an inclined surface 28, and the side away from the first sewage outlet 25 is an arc surface 29.

[0070] By providing the protrusion 27 , the adhered matter in the scraping chamber 8 can be easily collected into the cleaning box 4 through the inclined surface 28 . Meanwhile, when the scraping member 6 retracts, the arcuate surface 29 can easily retract the scraping member 6 into the through hole 5 .

[0071] Reference Figure 4The second sewage outlet 26 is provided with a check plate 30.

[0072] In this embodiment, the non-return sheet 30 is made of elastic material, can be flipped toward the inside of the cleaning box 4 and has the ability to recover. The non-return sheet 30 prevents adhered matter in the cleaning box 4 from flowing back into the scraping chamber 8.

[0073] Reference Figure 4 The inclination angle of the contact surface between the wedge ring 10 and the wedge ring 2 11 is 70°.

[0074] By setting a large inclination angle, the contact area between wedge ring 10 and wedge ring 2 11 is increased, and the friction between wedge ring 10 and wedge ring 2 11 is increased, so that wedge ring 10 and wedge ring 2 11 are not easy to separate after being squeezed into contact, and can only be separated by limiting ring 2 13 to block wedge ring 2 11.

[0075] Reference Figure 8 The contact surface between the scraping portion 7 and the welding head 3 is provided with a scraping line 31 .

[0076] In this embodiment, the scraping lines 31 are made of elastic material to ensure that the welding head 3 is not scratched during scraping. A plurality of scraping lines 31 are arranged in parallel to ensure that the friction force is locally increased in the scraping part 7. The scraping lines 31 increase the scraping effect of the scraping part 7 on the attachments on the welding head 3.

[0077] Reference Figure 7 The connection between the cleaning box 4 and the handle 1 is a detachable bottom cover 32, on which a pin 33 is provided, which is connected to the handle 1. By providing a detachable cleaning box 4, after the operation is completed, the cleaning box 4 can be removed from the handle 1, and the bottom cover 32 of the cleaning box 4 can be opened to collect the attached matter collected in the cleaning box 4.

[0078] Specific reference Figures 9-11 , which is the working principle of the present invention:

[0079] By providing a cleaning unit, when the scraper 6 extends from the through hole 5, it separates into upper and lower parts. After the wedge ring 10 moves to the position of the limit ring 12 and is pressed against the wedge ring 2 11, the upper and lower parts of the scraper 6 close together. During the retraction process of the scraper 6, the adhered matter on the welding head 3 is scraped off. After the wedge ring 10 moves to the position of the limit ring 2 13, the wedge ring 2 11 is restrained and separated from the wedge ring 10, completing one scraping operation. In this way, the scraper 6 first extends and then closes and retracts, and the adhered matter on the welding head 3 is cleaned into the scraping cavity 8, preventing the adhered matter from falling into the wound surface and being difficult to clean. This ensures that the welding head 3 is cleaned while ensuring intraoperative cleanliness.
