Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a disposable radiofrequency plasma electrode hook structure. Background Technology

[0002] Currently, the soft tissue hook knives commonly used in orthopedics and other departments for minimally invasive surgeries such as arthroscopy and percutaneous endoscopic discectomy are mostly reusable instruments with metal structures.

[0003] These types of hook-blades, primarily relying on mechanical methods to pull and cut soft tissue in clinical use, have the following drawbacks: First, their cutting efficiency is limited, easily leading to prolonged operation time and reduced surgical efficiency. Second, bleeding during the procedure cannot be controlled in a timely manner, often affecting the surgical field and reducing surgical efficiency. Third, tissue adhesion is easily caused after separating tissue with metal hook-blades, further reducing surgical efficiency. Fourth, reusable instruments pose a risk of cross-infection during cleaning and sterilization. Fifth, metal hook-blades experience wear and tear during use, reducing separation efficiency and impacting surgical efficiency.

[0004] In summary, there is a current need for a disposable radiofrequency plasma electrode hook knife structure that can improve surgical efficiency. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of the prior art and provide a disposable radiofrequency plasma electrode hook knife structure that can improve surgical efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A disposable radio frequency plasma electrode hook structure, comprising: A handle, on which a radio frequency plasma host connection wire is provided; The blade body has one end connected to the handle, and the other end of the blade bar is provided with a blade head. The blade body is electrically connected to the connecting wire of the radio frequency plasma host.

[0007] The radio frequency plasma host is connected via a connecting wire, enabling the blade to release radio frequency / plasma energy while cutting soft tissue. This invention, based on the traditional hook blade design, redesigns the blade as an electrode structure capable of releasing radio frequency / plasma energy, achieving rapid cutting superior to traditional mechanical hook blades and improving cutting efficiency. While pulling and cutting soft tissue, it can achieve immediate hemostasis through energy action, thus maintaining a clear surgical field and effectively preventing bleeding from obstructing the surgical view. Simultaneously, plasma cutting reduces thermal damage and carbonization, lowering the incidence of tissue adhesion, thereby significantly improving surgical efficiency.

[0008] Preferably, one end of the blade and the handle are integrally fixedly connected. The connecting wire of the radiofrequency plasma host is located at the tail end of the handle. A rotating seat is provided at the front end of the handle, and the rotating seat is rotatably connected to the handle. One end of the blade is fixed to the front end face of the rotating seat. An angle adjustment device connected to the rotating seat is also provided on the handle. The blade and handle are designed as a single unit, improving operational stability and safety. This invention operates similarly to a traditional hook knife, has a low learning curve, and can be widely applied in orthopedics, pain management, and other minimally invasive surgical fields, making it easy to promote. Doctors can control the rotation of the rotating seat through the angle adjustment device, which in turn rotates the blade, adjusting the angle of the blade tip and improving the flexibility of the electrode hook knife.

[0009] Preferably, one end of the blade and the handle are detachably connected. The radiofrequency plasma host connection wire is located at the tail end of the handle. A rotating seat is provided at the front end of the handle, and the rotating seat is rotatably connected to the handle. A blade mounting groove is provided on the front surface of the rotating seat, and one end of the blade is installed in the blade mounting groove and threadedly connected thereto. An angle adjustment device connected to the rotating seat is also provided on the handle. The detachable design of the blade and handle reduces usage costs and improves economy. This invention operates similarly to a traditional hook knife, has a low learning curve, and can be widely applied in orthopedics, pain management, and other minimally invasive surgical fields, making it easy to promote. Doctors can control the rotation of the rotating seat through the angle adjustment device, which in turn rotates the blade, achieving angle adjustment of the blade tip and improving the flexibility of the electrode hook knife.

[0010] Preferably, the front end face of the handle is provided with an annular limiting groove, and the rear end face of the rotating seat is fixed with a limiting block that matches the annular limiting groove. The rotating seat is mounted on the handle and rotatably connected to it through the cooperation of the limiting block and the annular limiting groove. The design of the annular limiting groove and the limiting block facilitates the mounting of the rotating seat at the front end of the handle and guides the rotation of the rotating seat.

[0011] Preferably, the angle adjustment device includes a rotating column fixed to the rear end face of the rotating seat. The handle has a cavity inside, and the front wall of the cavity has a rotating column through hole that matches the rotating column. The rotating column is placed in the rotating column through hole and rotatably connected to it. The cavity has a guide column and a rotating shaft inside. One end of the guide column is fixed to the end face of the rotating column, and the other end of the guide column is fixed with a bevel gear. The rotating shaft is installed in the cavity and rotatably connected to it. The rotating shaft and the guide column are arranged perpendicular to each other. A bevel gear and a spur gear are sleeved and fixed on the rotating shaft. The bevel gear and the bevel gear mesh with each other. The side wall of the handle has a sliding groove that communicates with the cavity. A slider is slidably connected to the sliding groove. A spur rack is fixed on the slider. The spur rack and the spur gear mesh with each other. When the angle of the blade needs to be adjusted, the doctor can slide the slider on the handle. First, the transmission between the rack and pinion drives the rotating shaft and the second bevel gear on it to rotate synchronously. Then, the transmission between the second bevel gear and the first bevel gear drives the guide post to rotate synchronously. This, in turn, drives the rotating post and the rotating seat fixed to the guide post to rotate synchronously. This allows the angle of the blade to be adjusted during the operation without rotating the handle, greatly improving the flexibility of using the electrode hook knife.

[0012] Preferably, the slide groove is located on one side wall of the chamber, and the slide groove is located on the side of the guide post, with the two arranged parallel to each other. The slider has a button through hole, and a button is slidably connected to the button through hole. A positioning frame is also provided in the chamber, and the guide post is located inside the positioning frame. One end of the button is located outside the slider, and the other end of the button is fixedly connected to one side of the positioning frame. The outer wall of the other side of the positioning frame is connected to the other side wall of the chamber by a spring. A locking gear is sleeved and fixed on the guide post, and locking teeth adapted to the locking gear are provided on the inner wall of the other side of the positioning frame. The distance between one side of the positioning frame and the other side of the positioning frame is greater than the diameter of the locking gear, and the length of the locking gear matches the length of the slide groove. In the natural state, the locking teeth on the positioning frame are pressed and engaged with the locking gear on the guide post under the elastic force of the spring, so that the guide post is locked and cannot rotate, thereby ensuring the stability of the electrode hook knife during normal use. When the blade angle needs to be adjusted, the doctor can first press the button on the slider. The locking teeth on the positioning frame disengage from the locking gear on the guide post, thus releasing the guide post from its locked state. Then, the doctor can adjust the blade angle by sliding the slider on the handle. The operation is simple and convenient. After the blade angle is adjusted, the doctor can release the button. At this time, the locking teeth on the positioning frame will automatically re-engage with the locking gear on the guide post under the return force of the spring, so that the guide post returns to the locked state.

[0013] Preferably, a guide plate movable groove is provided on the other side wall of the chamber. The guide plate movable groove and the sliding groove are arranged parallel to each other. A guide plate is slidably connected in the guide plate movable groove, and a guide rod is fixed on the guide plate. A guide tube matching the guide rod is fixed on the outer wall of the other side of the positioning frame. The guide rod is placed in the guide tube and slidably connected to it. The spring is located inside the guide tube and between the guide rod and the other side of the positioning frame. The cooperative design of the guide rod and the guide tube improves the installation stability of the positioning frame in the chamber; the cooperative design of the guide plate movable groove and the guide plate guides the movement of the positioning frame in the chamber.

[0014] Preferably, a conductive rod is fixed inside the rotating base. One end of the conductive rod contacts the blade body, and the other end contacts the guide post. The guide post, positioning frame, guide tube, guide rod, and guide plate are all made of conductive material. The guide plate and the radio frequency plasma host connecting wire are connected by an electrical wire. The slider and button are both made of insulating material. When the motor hook knife is in normal use, the radio frequency plasma host sequentially transfers radio frequency / plasma energy to the blade head of the blade body through the radio frequency plasma host connecting wire, electrical wire, guide plate, guide rod, guide tube, positioning frame, guide post, and conductive rod. When the blade angle needs to be adjusted, pressing the button to release the guide post's locking state disconnects the guide post from the positioning frame, temporarily shutting off the blade's power supply. This prevents accidental damage to surrounding normal tissue during blade rotation, further improving surgical safety. Once the blade angle adjustment is complete, releasing the button relocks the guide post, reconnecting it to the positioning frame. At this point, the blade can resume releasing radiofrequency / plasma energy to continue the surgery. Operation is simple and control is convenient.

[0015] Preferably, the outer surface of the slider is provided with a finger groove, and the button through hole is located on the bottom surface of the finger groove. The finger groove design facilitates the doctor's movement of the slider after pressing the button, improving operational convenience.

[0016] Preferably, an insulating sleeve is fixedly attached to the outer wall of the blade. This insulating sleeve design prevents accidental damage to surrounding healthy tissue by the side wall of the blade during surgery, thus improving surgical safety.

[0017] The beneficial effects of this invention are: improved cutting efficiency; improved surgical efficiency; the integrated design of the blade and handle enhances operational stability and safety; the detachable design of the blade and handle reduces usage costs and improves economy; easy to promote; improved flexibility in the use of the electrode hook knife; simple operation and convenient control; improved surgical safety; and improved ease of operation.

[0026] The slide groove 18 is located on one side wall of the chamber 10. The slide groove 18 is located on the side of the guide post 12 and the two are arranged parallel to each other. The slider 19 is provided with a button through hole 20. A button 21 is slidably connected to the button through hole 20. A positioning frame 22 is also provided in the chamber 10.

The spring 23 is located inside the guide tube 29 and is placed between the guide rod 28 and the other side of the positioning frame 22.

[0028] Inside the rotating base 5, there is also a conductive rod 30. One end of the conductive rod 30 is in contact with the blade body 2 (if the blade body 2 and the handle 1 are connected as one piece, the conductive rod 30 is directly connected to the blade body 2; if the blade body 2 and the handle 1 are detachably connected, one end of the conductive rod 30 is located on the inner wall of the blade body mounting groove 6 and is in contact with the blade body 2). The other end of the conductive rod 30 is in contact with the guide post 12. The guide post 12, the positioning frame 22, the guide tube 29, the guide rod 28, and the guide plate 27 are all made of conductive material. The guide plate 27 and the radio frequency plasma host connecting wire 4 are connected by a wire 31. The slider 19 and the button 21 are both made of insulating material.

[0029] The handle 1 has a drainage conduit and an infusion conduit inside. The rotating seat 5 has a first channel that matches one end of the drainage conduit and a second channel that matches one end of the infusion conduit inside.

To ensure the sealing between the first channel and the drainage channel, and between the second channel and the infusion channel, a sealing ring is provided at the connection.

[0030] like Figures 7-9 As shown, the drainage tube 34 and the infusion tube 36 can be connected to the handle 1 as needed on site, or one of them can be connected alone. The unconnected tube openings are sealed with plugs.

[0031] The outer surface of the slider 19 is provided with a finger groove 32, and the button through hole 20 is located on the bottom surface of the finger groove 32.

[0032] An insulating sleeve 33 is fixedly wrapped around the outer wall of the blade body 2.

[0033] This invention, based on the traditional hook knife design, incorporates a blade head 3 on the blade body 2 as an electrode structure capable of releasing radio frequency / plasma energy. This enables rapid cutting, superior to traditional mechanical hook knives, and significantly improves cutting efficiency. While traction and cutting soft tissue, it achieves immediate hemostasis through energy action, maintaining a clear surgical field and effectively preventing bleeding from obstructing the surgical view. Simultaneously, plasma cutting reduces thermal damage and carbonization, lowering the incidence of tissue adhesion, thus greatly improving surgical efficiency. The blade body 2 and handle 1 are detachable, avoiding cross-infection issues caused by repeated use and preventing the potential decrease in cutting efficiency that can occur with reused hook knives. The operation of this invention is similar to that of a traditional hook knife, with a low learning curve, making it widely applicable in orthopedics, pain management, and other minimally invasive surgical fields, and easy to promote.

[0034] When the angle of the blade head 3 needs to be adjusted, the doctor can first press the button 21 on the slider 19. The locking teeth 25 on the positioning frame 22 will disengage from the locking gear 24 on the guide post 12, thereby releasing the locking state of the guide post 12. Then, slide the slider 19 on the handle 1. First, the transmission between the rack 17 and the spur gear 15 will drive the rotating shaft 13 and its bevel gear 16 to rotate synchronously. Then, the transmission between the bevel gear 16 and the first bevel gear 14 will drive the guide post 12 to rotate synchronously. This will drive the rotating post 9 and the rotating seat 5, which are fixed to the guide post 12, to rotate synchronously as well. This allows the angle of the blade head 3 to be adjusted without rotating the handle 1 during the operation. After the angle of the blade head 3 is adjusted, the doctor can release the button 21. At this time, the locking teeth 25 on the positioning frame 22 will automatically re-engage with the locking gear 24 on the guide post 12 under the return force of the spring 23, so that the guide post 12 returns to the locked state.

[0035] When the motor-driven hook knife is in normal use, the radio frequency plasma host sequentially transmits radio frequency / plasma energy to the blade head 3 of the blade body 2 through the radio frequency plasma host connection wire 4, wire 31, guide plate 27, guide rod 28, guide tube 29, positioning frame 22, guide post 12, and conductive rod 30. When it is necessary to adjust the angle of the blade head 3, after pressing button 21 to release the locking state of guide post 12, guide post 12 and positioning frame 22 will be disconnected to temporarily shut off the power supply to the blade head 3, thereby preventing the blade head 3 from accidentally damaging surrounding normal tissue during rotation; after the blade head 3 angle is adjusted, releasing button 21 will cause guide post 12 to lock again, and guide post 12 and positioning frame 22 will be reconnected. At this time, the blade head 3 can release radio frequency / plasma energy normally to continue the surgery.
