Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a visual fascia knife. Background Technology
[0002] After surgery, problems such as tissue adhesions and scar contractures may occur at the surgical site. Visual fascia knife can be used during the recovery process to release adhesions, soften scars, promote local blood circulation, and accelerate wound healing and functional recovery through visualized manipulation.
[0003] A search revealed Chinese patent publication number CN221266246U, which discloses a fascia knife, comprising a fascia knife body, a male connector, a female connector, and a fixing screw. The female connector is fixed to the fascia knife body by the fixing screw, and the male connector and the female connector are connected by an insertion connection. This invention allows for the selection of a suitable fascia knife body model for connection with the female connector. The male connector is equipped with a cable, allowing for easy replacement of the required fascia knife model by simply plugging and unplugging the cable; it eliminates the need for a separate cable for each type of fascia knife.
[0004] The patent description mentioned above states that "the required model of fascia knife can be replaced simply by plugging and unplugging." However, the constant shaking and displacement of the knife head during use will subject the connection points of the visual fascia knife to additional stress and friction, accelerating wear and shortening its lifespan. This wear is particularly problematic for high-precision visual fascia knife devices, affecting performance and stability and increasing maintenance costs. To address these issues, a new visual fascia knife is proposed. Utility Model Content
[0005] The present invention proposes a visual fascia knife, which aims to improve the problem that some visual fascia knives in the prior art cannot adjust and lock the opening clamp.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A visual fascia knife includes a blade, a handle is fixedly connected to the outer right side of the blade, a Luer interface is fixedly connected to the outer right side of the handle, and an adjustment locking mechanism is fixedly connected to the outer right side of the Luer interface. The adjusting locking mechanism includes a locking button, which is externally fixedly connected to the outside of the Luer interface. The locking button is internally threaded with a locking bolt. An open clamp is provided inside the locking button. A cross groove is provided on the outer left side of the open clamp. A threaded groove is provided inside the locking button. A connecting pipe is fixedly connected to the outer right side of the locking button. An injection assembly is fixedly connected to the top of the Luer interface.
[0007] The above solution features: a handle connected to the right side of the scalpel for easy gripping and operation; a Luer interface for component connection; and a key adjustment and locking mechanism on the right side. The locking button, through its internal threaded groove and engagement with the locking bolt, controls the tightness of the opening chuck. The cross-groove design facilitates precise positioning, the connecting tube allows for easy connection of external equipment, and the top injection component enables on-demand medication during fascia treatment, improving both treatment effectiveness and convenience.
[0008] As a further description of the above technical solution: The drug delivery assembly includes a connecting tube, which is externally and fixedly connected to the top of the Luer interface, and a cleaning port is fixedly connected to the top of the connecting tube.
[0009] Through the above solution: the drug injection component, as an important part of the visual fascia knife, takes the connecting tube as the core carrier and is firmly fixed to the top of the Luer interface, thus constructing a stable drug delivery channel. The cleaning port set at the top of the connecting tube has a dual function: it can clean and disinfect the entire drug injection pipeline before surgery to ensure a sterile environment, and it can inject drugs or rinsing solutions as needed during treatment to meet the needs of different treatment scenarios and improve the safety and effectiveness of treatment.
[0010] As a further description of the above technical solution: The locking bolt is externally fixed to an ultra-fine endoscope, and the port of the cross groove radially retracts to clamp the ultra-fine endoscope.
[0011] The above solution involves a locking bolt tightly connected to the ultra-thin endoscope, forming a key visual component. When the locking button is turned, the internal thread drives the locking bolt to move, and the cross-shaped groove port retracts radially. Thanks to the precise mechanical design, the ultra-thin endoscope can be firmly clamped, ensuring its stability during fascia treatment, providing doctors with a clear field of vision, and facilitating precise operation.
[0012] As a further description of the above technical solution: A channel tube is fixedly connected to the outer right side of the tool holder, and the outer side of the channel tube is fixedly connected to the top of the tool bar.
[0013] With the above solution, the channel tube fixed on the right side of the outside of the handle not only serves as a connection but also as an important carrier for functional transmission. It is firmly fixed to the top of the handle and can form a through channel inside for transmitting drugs, irrigation fluids, etc. It can also serve as an auxiliary channel for the ultra-fine endoscope, ensuring the smooth operation of the instrument in fascia treatment and improving the continuity and convenience of the operation.
[0014] As a further description of the above technical solution: The outside of the channel tube is fixedly connected to the bottom of the connecting tube, and the outside of the channel tube communicates with the inside of the adjusting and locking mechanism.
[0015] The above solution ensures that the bottom of the channel tube is tightly fixed to the connecting tube, forming a continuous passage between the drug delivery component and the channel tube, facilitating drug delivery. Furthermore, its external structure is connected to the internal structure of the adjustment and locking mechanism, ensuring that the lighting, image transmission, and other pipelines required by the ultra-thin endoscope can pass through smoothly. This achieves efficient collaboration among the various functional modules of the instrument, providing a strong guarantee for precision treatment.
[0016] As a further description of the above technical solution: The ultra-fine endoscope is externally slidably connected inside the locking button.
[0017] The above-mentioned design incorporates an ingenious combination of an ultra-thin endoscope and a locking button in the visual fascia knife. The ultra-thin endoscope can slide flexibly inside the locking button, allowing doctors to precisely adjust the endoscope's position according to actual needs before use to obtain the best observation angle. Once the position is determined, the endoscope is securely fixed through the synergistic action of the locking bolt and the opening clamp, ensuring the stability and accuracy of observation during the treatment procedure.
[0018] As a further description of the above technical solution: The handle has multiple threaded connection holes on both the front and rear sides, and the blade is fixedly connected to the left side of the handle.
[0019] The aforementioned design features multiple threaded connection holes on both the front and rear sides, facilitating the installation of auxiliary devices or the replacement of different functional accessories to meet diverse treatment needs. The blade fixed to the left side of the scalpel is made of high-strength, wear-resistant material, with a sharp edge and precise angle, enabling precise cutting and release of fascia tissue under the visual guidance of an ultra-fine endoscope, thus improving treatment outcomes.
[0020] As a further description of the above technical solution: The outer left side of the open clamp contacts the inside of the locking button, and the outer right side of the open clamp contacts the inner left side of the locking bolt.
[0021] The above solution utilizes the key position of the opening chuck. Its outer left side is in close contact with the inside of the locking button to ensure stable positioning within the entire structure, while its outer right side is in contact with the inside left side of the locking bolt. When the locking bolt is rotated, this contact allows the opening chuck to produce radial contraction or expansion as required, thereby accurately clamping or releasing the ultra-fine endoscope, ensuring flexible and reliable operation of the equipment.
[0022] This utility model has the following beneficial effects: 1. In this utility model, this design gives it a certain elastic deformation capability. At the same time, the outer wall of the opening clamp is provided with a second wedge surface. When the locking bolt and the locking button are connected by threads and tightened, the locking bolt abuts the opening clamp to the left. At this time, under the pushing and action of the first wedge surface, the port with the cross groove is radially contracted, thereby firmly clamping the ultra-fine endoscope and ensuring its stable and reliable fixation.
[0023] 2. In this utility model, by injecting water or medicine into its interior, the dynamic principle of liquid flow is used to allow the medicine or water to smoothly enter the interior of the channel tube along the connecting tube. The flushing tube connected to the channel tube can accurately deliver the injected water or medicine to the surgical site. Whether it is to remove impurities or residual tissue from the surgical site or to inject therapeutic drugs in a timely manner, this device can complete the task efficiently, effectively reduce the risk of infection, and improve the safety and reliability of the surgery.

When the locking bolt 42 is threadedly connected to the locking button 41, it abuts against the opening clamp 43 to the left. Under the action of the first wedge surface, the second wedge surface causes the port with the cross groove 44 to radially contract and clamp the ultra-fine endoscope 5. The opening clamp 43 is specially provided with a cross groove 44 on one end of the opening clamp facing the locking button 41. This design gives it a certain elastic deformation capability. At the same time, the second wedge surface is provided on the outer wall of the opening clamp 43. When the locking bolt 42 and the locking button 41 are connected by threads and tightened, the locking bolt 42 abuts against the opening clamp 43 to the left. At this time, under the pushing and action of the first wedge surface, the port with the cross groove 44 is radially contracted, thereby firmly clamping the ultra-fine endoscope 5 and ensuring its stable and reliable fixation. As an important operating inlet, the cleaning port 4702 allows water or medication to be injected into it. Utilizing the dynamic principle of liquid flow, the medication or water smoothly enters the channel tube 6 through the connecting tube 4701. The flushing tube connected to the channel tube 6 can accurately deliver the injected water or medication to the surgical site. Whether it is removing impurities or residual tissue from the surgical site or injecting therapeutic drugs in a timely manner, this device can complete the task efficiently, effectively reducing the risk of infection, improving the safety and reliability of the surgery, and providing a strong guarantee for the smooth progress of the surgery.
