[0001] The utility model relates to a minimally invasive dissector, in particular to a minimally invasive dissector for facial ligaments. Background Art

[0002] Minimally invasive dissectors are precision instruments specifically designed for minimally invasive surgery. Their primary function is to dissect tissue, separate adhesions, or excise lesions during surgery to achieve therapeutic results. Minimally invasive dissectors are a general term for medical surgical instruments, and they come in a variety of types and designs, depending on the surgical site and intended use. For example, nerve dissectors are primarily used for nerve dissection in orthopedic surgery, while sinusoscope dissectors are used for minimally invasive treatment of nasal conditions such as sinusitis and nasal polyps. There are also dissectors for minimally invasive dissection of skin and subcutaneous tissue, as well as prostate dissectors.

[0003] A minimally invasive facial ligament dissector is a device specifically designed for minimally invasive facial surgery. It is intended to minimally invasively dissect facial ligaments and surrounding tissues to achieve lifts, tightening, or treatment of specific facial conditions.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0027] like Figure 1 and Figure 2 As shown, a minimally invasive dissector for facial ligaments includes: a handle portion 1, an adjustment portion 2, an operating portion 3, a blade portion 4 and a light rod 5; the handle portion 1 includes a fixing block 1.1, a first grip 1.2 and a second grip 1.3, the first grip 1.2 and the second grip 1.3 are hinged, and the second grip 1.3 is connected to the light rod 5. Holding and pressing the second grip 1.3 is used to adjust the position of the light rod 5, so that the doctor can easily control the movement of the dissector with one hand, thereby improving the convenience and efficiency of the operation.

[0028] The adjustment portion 2 includes a chute 2.1, a slider 2.2, and an adjustment rod 2.3. One end of the adjustment rod is fixedly connected to the slider, while the other end extends into the operating portion 3 and is fixedly connected to one end of the operating portion 3. This pushes the slider 2.2 to slide within the chute 2.1, causing the operating portion 3 to deform under the traction of the adjustment rod 2.3. One end of the operating portion 3 is provided with a first fixing ring 6 and a second fixing ring 7. A fixing frame 8 is provided between the first and second fixing rings 6 and 7, and the blade portion 4 passes through the first and second fixing rings 6 and 7. The interaction between the chute 2.1, slider 2.2, and adjustment rod 2.3 allows the surgeon to flexibly adjust the angle and position of the dissector as needed during surgery to accommodate different surgical scenarios.

[0029] like Figure 3As shown, the operating part 3 has multiple layers, including, from the outside to the inside: a protective layer 3.1, a thick-walled layer 3.2, a spring layer 3.3 and a textile layer 3.4; it provides good protection performance, prevents accidental damage during the operation, and ensures the service life of the stripper. The adjusting rod 2.3 is located in the thick-walled layer 3.2, and the textile layer 3.4 is wrapped around the outer surface of the light rod 5. The protective layer 3.1 is made of one of rubber, silicone or memory metal. The thick-walled layer 3.2 is made of silicone or sponge material. The protective layer 3.1, the thick-walled layer 3.2, the spring 2.6 layer and the textile layer 3.4 are adjacently combined together by sterile gel or sewing. The spring layer 2.6 can enable the operating part 3 to undergo elastic deformation, better adapt to the morphological changes of the surgical site, and improve the adaptability and effect of the operation.

[0030] like Figure 4 As shown, a limiting tooth 2.5 is hingedly connected to one side of the slider 2.2. A spring 2.6 is provided between the limiting tooth 2.5 and the slider 2.2. A limiting slot 2.7 is provided within the chute 2.1, and one end of the limiting tooth 2.5 can be inserted into the limiting slot 2.7. An adjustment frame 2.4 is provided on the slider 2.2. The adjustment frame 2.4 is slidably connected to the slider 2.2. When the adjustment frame 2.4 is pushed, the end of the adjustment frame 2.4 abuts the limiting tooth 2.5. The interaction between the limiting tooth 2.5 and the limiting slot 2.7 enables precise locking and unlocking of the slider 2.2, ensuring the precise positioning of the dissector during surgery. The adjustment frame 2.4 allows the surgeon to easily lock and unlock the position by pushing, improving the convenience of the surgery.

[0031] Both the polished rod 5 and the adjustment rod 2.3 are made of rubber. The bending angle of the operating portion 3 is adjustable from 0 to 15 degrees, allowing the surgeon to make precise adjustments as needed to achieve the optimal surgical effect. A cutting tool is hingedly connected to the end of the blade portion 4. The diameter of the cutting tool changes with the displacement of the polished rod 5. The minimum diameter of the cutting tool is consistent with the inner diameter of the second fixing ring 7.

[0032] When the present invention is used, the handle portion 1 comprises a fixed block 1.1, a first grip 1.2 and a second grip 1.3 for distinction. The second grip 1.3 is hinged to the fixed block 1.1, allowing the user to operate the second grip 1.3 to achieve translational sliding of the polished rod 5 within the operating portion 3.

[0033] When the user holds and moves the second handle 1 . 3 , the polished rod 5 will slide in the operating portion 3 , and this movement will be transmitted to the adjusting portion 2 , thereby affecting the states of the operating portion 3 and the blade portion 4 .

[0034] The adjustment portion 2 includes a chute 2.1, a slider 2.2, and an adjustment rod 2.3. One end of the adjustment rod 2.3 is connected to the operating portion 3, and the other end is connected to the slider 2.2. The movement of the slider 2.2 pulls the adjustment rod 2.3, thereby causing the operating portion 3 to deform, such as bend or twist, to adapt to surgical needs.

[0035] The operating portion 3 is constructed from multiple layers, including a protective layer 3.1, a thick-walled layer 3.2, a spring layer 3.3, and a textile layer 3.4. The adjustment rod 2.3 is located within the thick-walled layer 3.2, while the smooth rod 5 is wrapped in the textile layer 3.4. When the adjustment rod 2.3 is pulled, the deformation of the operating portion 3 is achieved through the elasticity and flexibility of its internal structure, with the spring layer 3.3 playing a key role.

[0036] The bending angle of the operating portion 3 can be adjusted within a range of 0 to 15 degrees, thereby allowing the doctor to adjust the angle of the dissector as needed during surgery.

[0037] The blade portion 4 passes through the first fixing ring 6 and the second fixing ring 7 of the operating portion 3. A fixing frame 8 is provided between the two fixing rings to maintain stability. A tool is hinged at the end of the blade portion 4. The diameter of the tool can change with the displacement of the polished rod 5.

[0038] When the polished rod 5 slides, it adjusts the diameter of the tool through some mechanism (which may be directly connected or through an intermediate component). The minimum diameter of the tool is consistent with the inner diameter of the second fixing ring 7. This ensures that the tool can pass through the fixing ring smoothly when it is at the minimum diameter, and the diameter can be expanded for stripping operation when necessary.

[0039] A limit tooth 2.5 is hinged on one side of the slider 2.2, and a spring 2.6 is provided between the limit tooth 2.5 and the slider 2.2. A limit groove 2.7 is provided in the slide groove 2.1, and one end of the limit tooth 2.5 can be embedded in the limit groove 2.7, which provides the locking and unlocking function of the position of the slider 2.2.

[0040] An adjustment frame 2.4 is also provided at the slider 2.2. Pushing the adjustment frame 2.4 can cause its end to abut against the limiting tooth 2.5, thereby unlocking or locking the position of the slider 2.2, so that the doctor can accurately control the position and state of the stripper during surgery.

[0041] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
