Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an eye bag fixator that is easy to adjust and use. Background Technology

[0002] Eyelid bag surgery involves surgically removing some of the loose skin, orbicularis oculi muscle, and protruding fat pads from the lower eyelid through specific methods and techniques. The layers are then meticulously and accurately sutured to achieve the desired effect of removing eye bags. Eyelid bag reduction surgery is the most common method for removing eye bags and an important component of cosmetic eye surgery.

[0003] Retractors are commonly used in blepharoplasty to help position the blepharoplasty ligaments, but existing retractor structures have the following drawbacks:

[0004] 1. The structure is simple and the adjustability is poor. During eye bag surgery, the hooks need to be temporarily removed and tightened again when adjusting the position of the eye bags. Therefore, the operator needs to constantly find the drape to position and tighten them. This operation is inconvenient. In addition, the hooks are usually taut. When adjusting the tilt angle, the above operation is also required to complete the repositioning and tightening. This operation is very inconvenient.

[0005] 2. The retractor requires an assistant to tighten the eye bags, making it impossible for a single person to operate, which increases labor costs and reduces the surgeon's operating space, making it difficult to perform the surgery efficiently.

[0006] To address the above issues, an eye bag fixator that is easy to adjust and use is proposed. Utility Model Content

[0007] The main purpose of this invention is to provide an eye bag fixator that is easy to adjust and use, thus solving the problems mentioned in the background art.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] An eye bag fixator that is easy to adjust and use includes a winch housing, a tensioning mechanism is provided inside the winch housing, a rotation positioning mechanism is fixedly connected to the outer side wall of the winch housing, and a clamping mechanism is also assembled inside the end of the rotation positioning mechanism away from the winch housing.

[0010] The tensioning mechanism includes a worm gear rotatably mounted to the bottom of the winch housing, a winding reel detachably mounted to the bottom of the worm gear, a worm engaging on the outer wall of the worm gear, the two ends of the worm rotatably supporting the inner wall of the winch housing, and a drive wheel nested at the end of the worm extending outside the winch housing.

[0011] The rotary positioning mechanism includes a U-shaped frame that is integrally fixed to the outer wall of the winch housing. The frame arm of the U-shaped frame has a structure that is shorter at the top and longer at the bottom. A shaft pin is rotatably installed in the lower frame arm. A locking gear is fixedly sleeved on the top of the shaft pin. A ratchet is engaged in the teeth of the locking gear.

[0012] The clamping mechanism includes clamping clamps that are rotatably mounted to the pivot pin.

[0013] Furthermore, a steel wire is wound on the winding reel, and the steel wire is slidably disposed with a clearance hole opened on the outer shell of the winch. An eye bag hook is hinged to one end of the outer side of the steel wire.

[0014] Furthermore, a spring box is fixed on the upper arm of the U-shaped frame, and symmetrical springs are pressed inside the spring box. One end of each spring is fixedly connected to a movable block that slides and limits the spring box, and a push rod is threadedly connected to the top of the movable block.

[0015] Furthermore, one end of the ratchet is fixed to the outer wall of the movable block.

[0016] Furthermore, the pivot pin passes through the clamping clamp, and the clamping clamp slides freely within the cavity of the U-shaped frame.

[0017] Furthermore, two sets of symmetrical locking racks are integrally welded to the clamp wall of the clamp.

[0018] The beneficial technical effects of this utility model are as follows:

[0019] This utility model, through the design of an eye bag fixing device consisting of a tensioning mechanism, a clamping mechanism, and a rotation positioning mechanism, can achieve the following:

[0020] 1. The clamping forceps hold one end of the retractor to the sterile surgical drape on the client's chest. The retractor is used to tighten and fix the eye bags. This method frees up the assistant to help position the retractor, allowing the operation to be completed by a single person. It also provides a larger operating space for the operation, making it convenient for the doctor to operate flexibly and accurately.

[0021] 2. The tensioning mechanism, through the worm gear, worm, and winding reel components inside the winch housing, allows for flexible adjustment of the hook wire. This facilitates free adjustment of the tension at different locations of the eye bags, overcoming the drawbacks of traditional fixed hook structures that are difficult to adjust. In conjunction with the U-shaped frame, spring box, and ratchet in the rotation positioning mechanism, the inclination angle of the wire can be further adjusted to tighten the eye bags at different angles, facilitating surgical operations for doctors.

[0029] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0030] like Figures 1-5As shown, this embodiment provides a conveniently adjustable eye bag fixator, including a winch housing 1. A tensioning mechanism 4 is disposed inside the winch housing 1. A rotation positioning mechanism 5 is fixedly connected to the outer wall of the winch housing 1. A clamping mechanism 3 is also assembled inside the end of the rotation positioning mechanism 5 away from the winch housing 1. The tensioning mechanism 4 includes a worm gear 401 rotatably mounted to the bottom of the winch housing 1. A winding reel 404 is detachably mounted to the bottom of the worm gear 401. A worm 402 meshes with the outer wall of the worm gear 401. The two ends of the worm gear 402 are rotatably supported by the inner wall of the winch housing 1. The end of the worm gear 402 extending to the outside of the winch housing 1 is nested with a drive wheel 403. The rotation positioning mechanism 5 includes a U-shaped frame 501 that is integrally fixed to the outer wall of the winch housing 1. The frame arm of the U-shaped frame 501 has a structure that is shorter at the top and longer at the bottom. A shaft pin 504a is rotatably arranged in the lower frame arm. A locking gear 504 is fixedly sleeved on the top of the shaft pin 504a. A ratchet 505 is meshed in the teeth of the locking gear 504. The clamping mechanism 3 includes a clamping clamp 301 that is rotatably mounted to the shaft pin 504a.

[0031] In the above structure, the U-shaped frame 501 and the winch housing 1 rotate synchronously along the shaft pin 504a. The bottom of the shaft pin 504a has a raised structure to lock the bottom of the U-shaped frame 501. The worm gear 401 and the worm 402 are unidirectional transmissions, with the transmission from the worm 402 to the worm gear 401, thus achieving the purpose of reverse locking. The winch housing 1 can be opened from the top, and after disassembling the winding reel 404, the steel wire 405 can be cleaned and disinfected.

[0032] A steel wire 405 is wound on the winding reel 404. The steel wire 405 is slidably connected to the avoidance hole opened on the winch housing 1. An eye bag hook 2 is hinged to one end of the steel wire 405. The eye bag hook 2 can rotate freely along the steel wire 405 and can be easily disassembled and replaced with different types of hook structures.

[0033] A spring box 502 is fixed to the upper arm of the U-shaped frame 501. Symmetrical springs are pressed inside the spring box 502. One end of each spring is fixedly connected to a movable block that slides within the spring box 502. A push rod 503 is threadedly connected to the top of the movable block. One end of a ratchet 505 is fixed to the outer wall of the movable block. When the movable block compresses the spring, the ratchet 505 disengages from the locking gear 504, allowing the U-shaped frame 501 to rotate freely. After release, the end of the ratchet 505 is pushed into the locking gear 504. The locking gear 504 is a fixed gear structure, which can thus prevent the ratchet 505 from rotating, thereby limiting the movement of the winch housing 1. The push rod 503 can move the movable block within the spring box 502 and also allows the U-shaped frame 501 to swing left and right.

[0034] The pin 504a passes through the clamp 301, and the clamp 301 slides freely with the inner cavity of the U-shaped frame 501. Two sets of symmetrical locking racks 301a are integrally welded on the clamp wall of the clamp 301.

[0035] The clamping forceps 301 have anti-slip textures on the inner wall of the forceps head. After clamping the client's surgical sterile drape, the clamping action with the locking teeth 301a provides a clamping and fixing effect at one end.

[0036] Working principle of this device: When in use, the eye bag hook 2 is hooked and fixed to the eye bag. The drive wheel 403 is rotated in the reverse direction, which drives the worm gear 402 to rotate. The worm gear 402 drives the worm wheel 401 to rotate, causing the winding reel 404 to release the steel wire 405 to a suitable length. The clamping forceps 301 retracts inward, and the forceps head clamps the surgical sterile drape on the client's chest. The two sets of locking teeth 301a are staggered and interlocked to maintain the clamping forceps 301. The drive wheel 403 is rotated in the forward direction, and the winding reel 404 tightens the steel wire 405, maintaining the eye bag hook 2's tightness and positioning on the eye bag.

[0037] When the tilt angle of the steel wire 405 needs to be adjusted, the doctor manually moves the push rod 503. The push rod 503 moves within the spring box 502 and compresses the spring, while simultaneously moving the ratchet 505, disengaging from the teeth of the locking gear 504. When the push rod 503 is rotated to both sides, the bottom of the U-shaped frame 501 rotates along the shaft pin 504a, causing the winch housing 1 to swing to one side, and the steel wire 405 tilts. If the length is insufficient at this time, the drive wheel 403 is rotated to adjust the length of the steel wire 405 to avoid pulling on the eye bags. After the adjustment is completed, the push rod 503 is released, and the ratchet 505 engages in the teeth of the locking gear 504, locking the top of the U-shaped frame 501, thus locking the U-shaped frame 501 as a whole to prevent rotation, thereby locking the position of the steel wire 405.

[0038] The above structure allows for the completion of eyelid surgery by a single person, and the tightening and fixation of the eyelids has a flexible adjustment method, which helps the doctor to carry out the surgical actions.
