Description

Technical Field

[0001] This utility model relates to the field of eyelid plastic surgery dissectors, and more specifically, to eyelid plastic surgery dissectors. Background Technology

[0002] In the field of contemporary medical aesthetics and plastic surgery, blepharoplasty, as a common and delicate facial surgery, is increasingly favored by patients. It not only improves age-related eyelid sagging but also corrects aesthetically displeasing defects such as ptosis and prominent eye bags. In these delicate surgeries, precise dissection of eyelid tissue is crucial for success, requiring surgeons to accurately separate and trim different eye tissues such as skin, muscle, and fat. However, currently widely used blepharoplasty dissectors have significant technical limitations. These tools largely borrow structural features from traditional scissors, employing a double-bladed, cross-cutting mechanism. While they achieve basic tissue separation, surgeons struggle to precisely control the dissector's cutting depth, range, and force during actual operation. Especially when dealing with areas like the eyelid, which have complex anatomy, rich tissue layers, and a thickness of only a few millimeters, existing dissectors cannot provide sufficient operational precision feedback, making it difficult for surgeons to accurately perceive changes in resistance and the degree of cutting as the tool acts on different tissue layers. This lack of precision makes it easy for the surgeon to over- or under-dissect during the operation. The surgeon needs to make repeated adjustments based on personal experience, which not only prolongs the operation time and increases the patient's anesthesia risk, but may also damage surrounding normal structures, such as the orbicularis oculi muscle, lacrimal gland or neurovascular bundle, in the case of excessive tissue dissection, leading to adverse consequences such as postoperative bleeding, scar formation, and eyelid dysfunction.

[0003] From a medical device engineering perspective, the shortcomings of existing eyelid surgery dissectors are mainly reflected in three aspects. First, in terms of tool structure design, traditional dissectors mostly use fixed blade opening angles and cutting edge lengths, which cannot be adjusted in real time according to individual differences in the eye anatomy of different patients or different tissue types encountered during surgery. This leads to surgeons having to frequently change dissectors of different sizes at different stages of the surgery, interrupting the surgical procedure. Second, in terms of force feedback mechanisms, existing dissectors lack a precise force control system. Surgeons mainly rely on feel to judge the cutting depth and tissue resistance during dissection. This subjective perception is easily affected by the surgical environment, the surgeon's condition, and individual skill level, making it difficult to achieve standardized and precise operation.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an eyelid plastic surgery dissector, which has the following beneficial effects:

[0017] This innovative blepharoplasty dissector effectively solves the clinical challenge of controlling the cutting depth in delicate operations with traditional blepharoplasty devices by introducing a precise and adjustable cutting range control mechanism, providing a more accurate and safer surgical tool option for blepharoplasty. The core innovation of this dissector lies in its unique adjustment mechanism design, enabling surgeons to adjust the cutting range and depth in real time according to the different eye anatomy characteristics of different patients, the dissection needs of different surgical stages, and the characteristics of different eye tissues. Its working principle involves adding a two-way adjustment system to traditional medical scissors. By pinching the two-way control component located on the side of the handle, the surgeon temporarily releases the internal locking mechanism, and can then easily adjust the maximum opening and closing range and cutting depth of the scissors. After adjustment, releasing the two-way control component causes the internal elastic locking plate to automatically reset and engage with the preset slot, thus firmly locking the adjusted cutting range. This ensures stable and controllable cutting depth during the operation and prevents over-cutting caused by uneven force applied by the surgeon's hand or minor tremors during operation.

[0018] This design enhances the safety and precision of eyelid surgery from multiple dimensions. From a surgical precision perspective, this dissector allows for precise control of eyelid tissue dissection. Surgeons can set the optimal cutting range based on preoperative planning, maintaining a consistent dissection depth and range whether it's only superficially dissecting the eyelid skin or precisely trimming the orbicularis oculi muscle or orbital fat. This avoids the accidental damage to surrounding tissues that can occur with traditional dissectors due to their inability to limit cutting depth, such as excessive removal of eyelid muscles, lacrimal gland damage, or transection of nerve bundles. From a surgical procedure optimization perspective, traditional eyelid surgery requires surgeons to change dissectors of various sizes for different dissection stages. This adjustable design allows a single tool to be easily adjusted to meet the different needs throughout the entire surgical process, reducing tool changes, shortening surgical time, and lowering the patient's anesthesia risks and surgical trauma.

[0028] Please see Figure 1-5An eyelid plastic surgery dissector includes medical scissors 1. The movable scissors are equipped with an adjustment mechanism, which includes handles 2, inner sleeves 3, side blocks 4, and top blocks 5. Two handles 2 are provided, each mounted on one side of the medical scissors 1. An inner sleeve 3 is mounted on the inner wall of each handle 2. A top block 5 is coaxially mounted on each inner sleeve 3. Multiple side blocks 4 are evenly spaced on the lower end face of each top block 5. These side blocks 4 are slidably connected within the inner sleeve 3. Multiple arc-shaped grooves 6 are evenly spaced on the side wall of each side block 4. Multiple bidirectional plates 7 are symmetrically arranged at equal intervals on the inner wall of the inner sleeve 3, and these bidirectional plates 7 are respectively engaged within the arc-shaped grooves 6. Multiple side plates are evenly spaced on the side wall of the inner sleeve 3. The groove 8 has a middle plate 18 slidably connected to each side groove 8. Two sets of middle plates 18 are symmetrically arranged, and two sets of middle plates 18 are provided with bidirectional discs 9. A slider 10 is provided on the side of the middle plates 18 near the axis. A push plate 11 is provided on each slider 10. An arc ring 12 is provided on both sides of the two push plates 11, and the arc ring 12 abuts against the multiple bidirectional plates 7. A positioning rod 13 is coaxially provided in the top block 5. A positioning hole 14 is opened on the lower end face of the inner sleeve 3. A rounded corner 15 is opened on the positioning rod 13 and the positioning hole 14. The sliders 10 are slidably connected to the side walls of the two side blocks 4. A fixed hook 16 is rotatably provided on one handle 2, and a fixed block 17 is fixed on the other handle 2.

[0029] In this embodiment, during eyelid plastic surgery, the cutting range of the medical scissors 1 needs to be adjusted for different situations to facilitate their use. First, the two bidirectional discs 9 are pinched together, and the sliding connection between the middle plate 18 and the side groove 8 is ensured to limit the sliding. Then, the two push plates 11 are brought closer to each other so that the arc rings 12 abut against the upper and lower sets of bidirectional plates 7 respectively. At this time, the locking between the bidirectional plates 7 and the arc groove 6 is released, so the position between the top block 5 and the internal tube can be adjusted, thus completing the adjustment process. After the adjustment is completed, the bidirectional discs 9 are released. Since the bidirectional plates 7 are elastic, they can be reset and locked in the arc groove 6, thus completing the locking process.

[0030] More specifically, when long-term storage is required, it needs to be secured to prevent injury. The fixing hook 16 is locked onto the fixing block 17, thus ensuring that the medical scissors 1 is in a fixed state and thereby ensuring the safety of use.

[0031] In summary, during the use or operation of the overall equipment: When performing eyelid plastic surgery, the cutting range of the medical scissors 1 needs to be adjusted according to different situations to facilitate different applications. First, by pinching the two bidirectional discs 9 together, the sliding connection of the middle plate 18 within the side groove 8 ensures the limiting of the sliding. Then, the two push plates 11 move closer to each other, causing the arc rings 12 to abut against the upper and lower sets of bidirectional plates 7 respectively. At this time, the locking between the bidirectional plates 7 and the arc groove 6 is released, thus allowing the adjustment of the position between the top block 5 and the internal tube, thereby completing the adjustment process. After the adjustment is completed, the bidirectional discs 9 are released. Due to the elasticity of the bidirectional plates 7, they can be reset and locked within the arc groove 6, thus completing the locking process.

[0032] When long-term storage is required, it needs to be secured to prevent injury. The fixing hook 16 is locked onto the fixing block 17, thus ensuring that the medical scissors 1 is in a fixed state and thus ensuring the safety of use.

[0033] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
