Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a visual retractor system for surgical release of orbital fat in eye bags. Background Technology
[0002] Eyelid bag surgery is primarily based on ocular anatomy, including the eyeball, eyelids, conjunctiva, lacrimal apparatus, and extraocular muscles. The normal anatomical relationships of these structures are crucial for the safety and effectiveness of the surgery. Eyelid bag surgery requires precise and meticulous intraoperative dissection and layered, regional internal fixation, as well as orbital fat release. It incorporates several advanced techniques, such as microsurgery, laser technology, and endoscopy. Microsurgery provides a clearer surgical field, reducing surgical trauma and complications; laser technology, with its high precision and high energy, improves surgical accuracy and safety; and endoscopy allows surgeons to clearly observe internal structures and perform delicate procedures.
[0003] However, current endoscopic technology has a limited scope of application, relatively simple application procedures, and poor anatomical exposure, which cannot ensure the safety and effectiveness of the surgery.
[0004] Therefore, it is necessary to develop a visual retractor system specifically for orbital fat release surgery to overcome the aforementioned technical problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a visual retractor system for surgical release of orbital fat in eye bags, which effectively overcomes the defects of the prior art.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

One end of the main retractor is provided with a main hook body, and one end of each of the pair of auxiliary retractors is provided with an auxiliary hook body. The pair of auxiliary retractors are mounted on the main retractor, and the auxiliary hook bodies at one end of each retractor are distributed on both sides of the main hook body. The pair of auxiliary retractors can be moved relative to each other until the auxiliary hook bodies are close to the main hook body from both sides, or moved away from the main hook body from both sides. A camera system is provided on the main retractor near the main hook body.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, the main hook includes a long straight operating rod and a long straight extension arm inclinedly disposed at one end of the operating rod.

[0010] Furthermore, the aforementioned auxiliary hook includes a long straight connecting rod and an auxiliary hook body disposed at one end of the connecting rod. The connecting rods of the pair of auxiliary hooks are distributed crosswise, and the intersection point is assembled to one side of the extension arm by a pin passing through both. An operating part is provided at the other end of the connecting rod.
[0011] Furthermore, the aforementioned auxiliary hook is a long, straight rod, one end of which is connected to the aforementioned connecting rod. The ends of the pair of aforementioned auxiliary hooks that are away from the aforementioned connecting rod extend obliquely towards each other, and the ends are provided with bent feet.
[0012] Furthermore, an elastic support is connected between the operating parts of the pair of auxiliary hooks, and the elastic support is used to elastically open the pair of operating parts.
[0013] Furthermore, the aforementioned elastic support includes a guide rod and a spring.

[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0025] Example
[0026] like Figure 1 , 2 As shown in Figure 3, the visual retractor system for oculoplastic fat release surgery in this embodiment includes a main retractor 1 and a pair of auxiliary retractors 2. One end of the main retractor 1 is provided with a main hook body 111, and one end of each pair of auxiliary retractors 2 is provided with an auxiliary hook body 211. The pair of auxiliary retractors 2 are mounted on the main retractor 1, and the auxiliary hook bodies 211 at one end of the two are distributed on both sides of the main hook body 111. The pair of auxiliary retractors 2 can be moved relative to each other until the auxiliary hook bodies 211 of the two are close to the main hook body 111 from both sides, or moved away from the main hook body 111 from both sides. A camera system 3 is provided on the main retractor 1 near the main hook body 111.
[0027] The procedure for using the visual retractor system specifically designed for orbital fat release surgery in this embodiment is as follows:
[0028] The camera system 3 is connected to external equipment. During use, the main retractor 1 is operated so that the main hook 111 of the main retractor 1 is inserted into the lower eyelid and pulled forward (or downward and anteriorly) to expose the lower eyelid conjunctiva. Local anesthesia is then administered, and the doctor uses a scalpel or other instruments to cut open the conjunctiva. Then, the main hook 111 of the main retractor 1 enters the orbital septum. At the same time, the auxiliary hooks 211 of the pair of auxiliary retractors 2 also enter the orbital septum and are located on both sides of the main hook 111. The main retractor 1 is operated to pull forward (directly in front of the patient's face), and the main hook 111 pulls the orbital septum anteriorly. At the same time, the auxiliary hooks 211 of the pair of auxiliary retractors 2 are operated to move away from each other to the sides, thereby pulling the fat and tissue in the orbital septum to the sides, exposing the lower boundary of the orbital septum and fully exposing the internal space of the orbital septum. Then, surgical instruments can be used to remove (remove) the fat in the orbital septum. The entire process is captured in real time by the camera system 3, and the image information is fed back to the equipment and displayed on the equipment's screen. The doctor can operate the instruments through the field of vision on the screen throughout the operation, making the operation smooth and efficient.
[0029] In a preferred embodiment, the main hook 1 includes a long straight operating rod 11 and a long straight extension arm 12 inclined at one end of the operating rod 11. The end of the extension arm 12 away from the operating rod 11 is connected to the main hook body 111 that bends and extends toward the operating rod 11. The camera system 3 is provided on the extension arm 12, and a pair of auxiliary hooks 2 are mounted on the extension arm 12.
[0030] In the above implementation scheme, the extension arm 12 and the operating rod 11 are generally designed to form an angle of 45-60°. A blunted hook is provided at the end of the extension arm 12, which forms an acute angle with the extension arm 12. The hook is located within the orbital septum near the front (eyelid), and pulling it forward can open the eyelid, making the operation simple and convenient. Simultaneously, the camera system 3 on the extension arm 12 can effectively capture real-time images of the inside of the eyelid (including the inside of the orbital septum), providing a good surgical field of view in conjunction with external instruments, facilitating efficient surgery.
[0031] In a preferred embodiment, the auxiliary hook 2 includes a long straight connecting rod 21 and an auxiliary hook body 211 disposed at one end of the connecting rod 21. The connecting rods 21 of the pair of auxiliary hooks 2 are distributed crosswise, and the intersection point is assembled to one side of the extension arm 12 by a pin passing through both. The other end of the connecting rod 21 is provided with an operating part 22.
[0032] In the above implementation scheme, the design of the cross link 21 allows the secondary hook body 211 at one end of the secondary hook 2 to move closer or further away when the operating parts 22 of the pair of secondary hooks 2 are operated synchronously in opposite directions. When they move away, the fat and tissue in the orbital septum can be pulled to both sides. The operation is very simple and convenient, and provides a good surgical field of vision.
[0033] In a preferred embodiment, the aforementioned auxiliary hook 211 is a long straight rod, one end of which is connected to the aforementioned connecting rod 21. A pair of the aforementioned auxiliary hooks 211 extend obliquely toward each other away from the aforementioned connecting rod 21, and the ends are provided with bent feet 212.
[0034] In the above implementation scheme, the connecting rods 21 of the two auxiliary hooks 2 are in a plane, which is parallel to the plane where the extension arm 12 is located. After the main hook body 111 at the end of the extension arm 12 enters the orbital septum, the two auxiliary hook bodies 211 can also smoothly enter the orbital septum. With the relative displacement of the auxiliary hooks 2, the tissue and fat can be "distracted".
[0035] In a preferred embodiment, an elastic support 23 is connected between the operating parts 22 of the pair of auxiliary hooks 2, and the elastic support 23 is used to elastically open the pair of operating parts 22.
[0036] In the above implementation scheme, under normal conditions, the pair of operating parts 22 are relatively close to each other, that is, the auxiliary hooks 211 of the pair of auxiliary hooks 2 are relatively far apart. Before entering the orbital septum, an external force is applied to make the operating parts 22 relatively close (the elastic support 23 is compressed), that is, to make the auxiliary hooks 211 relatively close. After entering the orbital septum, after the main hook 111 pulls, the external force applied to the operating parts 22 is removed, the elastic support 23 returns to its deformation, the operating parts 22 are relatively far apart, and the pair of auxiliary hooks 211 are also relatively far apart, thus pulling the fat and tissue in the orbital septum apart to both sides. The operation is relatively simple and quick.
[0037] In this embodiment, the elastic support member 23 includes a guide rod 231 and a spring 232. One end of the guide rod 231 is connected to one of the operating parts 22, and the other end of the guide rod (231) passes through a matching hole on the other operating part 22. The spring 232 is sleeved on the guide rod 231, and its two ends are respectively connected to the two operating parts 22.
[0038] In this embodiment, the operating part 22 extends toward the other side of the extension arm 12. This positioning design ensures that the operating part 22 is outside the patient's eye when external force is applied, providing ample operating space.
[0039] In this embodiment, both the main hook 1 and the auxiliary hook 2 are made of stainless steel, which facilitates sterilization and disinfection.
[0040] Of course, the main hook 1 and the auxiliary hook 2 can also be made of other high-temperature resistant and sterilized medical materials.
[0041] In a preferred embodiment, the camera system 3 is a fiber optic camera, and the camera end of the camera system 3 extends along one end of the extension arm 12 and is close to the main hook body 111.
[0042] In the above implementation scheme, the fiber optic camera is arranged along the direction of the extension arm 12, with its end (i.e., the camera end) close to the main hook body 111, and its fiber optic tail end can be connected to the equipment.
[0043] In this embodiment, the camera end of the aforementioned fiber optic camera is equipped with a light source. This light source ensures good lighting inside the orbital septum during surgery, facilitating the camera's capture of the intraorbital septum environment, resulting in a better surgical field of view and clearer image quality.
