Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a visual retractor system specifically for the surgical operation of orbital septum fat release for eye bags. Background Art

[0002] The development of eye bag surgery is mainly based on ocular anatomy. It includes the eyeball, eyelid, conjunctiva, lacrimal apparatus, extraocular muscles, etc. The normal anatomical relationships of these structures are crucial for the safety and effectiveness of the surgery. Eye bag surgery requires precise and meticulous dissection during the operation and internal fixation in layers and regions, and orbital septum fat release is needed. Eye bag surgery incorporates some advanced techniques, such as microsurgery techniques, laser techniques, and endoscopic techniques. Among them, microsurgery techniques can provide a clearer surgical field of view, reducing the occurrence of surgical trauma and complications; laser techniques have the characteristics of high precision and high energy, capable of improving the accuracy and safety of the surgery; endoscopic techniques can help doctors observe the internal structures more clearly and perform delicate operations.

[0025] Embodiment

[0026] As Figure 1 、 2 、shown in 3, the visual retractor system dedicated to the surgical operation of orbital septum fat release for eye bags in this embodiment includes a main retractor 1 and a pair of sub-retractors 2. One end of the main retractor 1 is provided with a main hook body 111, and one end of each of the pair of sub-retractors 2 is respectively provided with a sub-hook body 211. The pair of sub-retractors 2 are installed on the main retractor 1, and the sub-hook bodies 211 at one end of the two are distributed on both sides of the main hook body 111. The pair of sub-retractors 2 can move relatively so that the sub-hook bodies 211 of the two approach the main hook body 111 from both sides, or move to be away from the main hook body 111 from both sides. A camera system 3 is provided at a position on the main retractor 1 close to the main hook body 111.

[0027] The usage process of the visual retractor system dedicated to the surgical operation of orbital septum fat release for eye bags in this embodiment is as follows:

[0028] The imaging system 3 is connected to external equipment and instruments. During use, the main retractor 1 is operated so that the main hook body 111 of the main retractor 1 extends into the lower eyelid and pulls the lower eyelid forward (or forward and downward on the side), exposing the conjunctiva of the lower eyelid. Then, local anesthesia is performed. The doctor uses a scalpel or other instrument to incise the conjunctiva. Then, the main hook body 111 of the main retractor 1 enters the orbital septum. At the same time, the sub-hook bodies 211 of a pair of sub-retractors 2 also enter the orbital septum and are located on both sides of the main hook body 111. The main retractor 1 is operated to pull forward (directly in front of the patient's face), and the main hook body 111 hooks and pulls the orbital septum forward. At the same time, the sub-hook bodies 211 of a pair of sub-retractors 2 are operated to move relatively away from each other on both sides, so as to pull the fat and tissue in the orbital septum to both sides, exposing the lower boundary of the orbital septum, and the internal space of the orbital septum can be fully exposed. Next, surgical instruments can be operated to remove (excise) and release the fat in the orbital septum. During the whole process, the imaging system 3 takes real-time pictures and feeds the picture information back to the equipment and instruments, and displays it on the display screen of the equipment and instruments. The doctor can operate the instruments throughout the operation through the visual field picture on the display screen, making the operation proceed smoothly and efficiently.

[0029] As a preferred embodiment, the above-mentioned main retractor 1 includes a long and straight operating rod 11 and a long and straight extension arm 12 obliquely arranged at one end of the operating rod 11. The end of the extension arm 12 far from the operating rod 11 is connected with the above-mentioned main hook body 111 that bends and extends towards the direction of the operating rod 11. The imaging system 3 is arranged on the extension arm 12, and a pair of the above-mentioned sub-retractors 2 are installed on the extension arm 12.

[0030] In the above-mentioned implementation scheme, the extension arm 12 and the operating rod 11 are generally designed to form an angle of 45 - 60°. A hook part with a blunt treatment is arranged at the end of the extension arm 12, and this hook part forms an acute angle with the extension arm 12. The hook part is close to the front (eyelid) in the orbital septum, and pulling forward can pull open the eyelid, which is simple and convenient to operate. At the same time, the imaging system 3 on the extension arm 12 can effectively take real-time pictures of the inside of the eyelid (including the inside of the orbital septum), cooperate with external instruments to provide a good surgical visual field, and is conducive to the efficient progress of the operation.

[0031] As a preferred embodiment, the above-mentioned sub-retractor 2 includes a long and straight connecting rod 21 and the above-mentioned sub-hook body 211 arranged at one end of the connecting rod 21. The connecting rods 21 of a pair of the above-mentioned sub-retractors 2 are cross-distributed, and the intersection point is assembled on one side of the extension arm 12 through a pin shaft penetrating both of them. An operating part 22 is arranged at the other end of the connecting rod 21.

[0032] In the above-mentioned implementation scheme, the design of the crossed connecting rod 21 can make the auxiliary hook body 211 at one end of the auxiliary retractor 2 relatively close to or far away from each other when the operating parts 22 of a pair of auxiliary retractors 2 are synchronously operated. When moving away from each other, the fat and tissue in the orbital septum can be pulled to both sides. The operation is very simple and convenient, providing a good surgical field of view.

[0033] As a preferred embodiment, the auxiliary hook body 211 is a long straight rod, one end of which is connected to the connecting rod 21 , and a pair of auxiliary hook bodies 211 extend obliquely toward each other from one end of the connecting rod 21 , and a bent foot 212 is provided at the end.

[0034] In the above embodiment, the connecting rods 21 of the two auxiliary retractors 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, and the relative displacement of the auxiliary retractors 2 can achieve the "pushing apart" of tissue and fat.

[0035] As a preferred embodiment, an elastic support member 23 is connected between the operating portions 22 of the pair of auxiliary hooks 2, and the elastic support member 23 is used to elastically expand the one-to-one operating portions 22.

[0036] In the above-mentioned implementation scheme, under normal conditions, a pair of operating parts 22 are in a relatively close state, that is, the auxiliary hook bodies 211 of a pair of auxiliary retractors 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 member 23 is compressed), that is, the auxiliary hook bodies 211 are relatively close. After entering the orbital septum, after the main hook body 111 is pulled, the external force applied to the operating part 22 is cancelled, the elastic support member 23 restores its deformation, the operating part 22 is relatively far apart, and the pair of auxiliary hook bodies 211 are also relatively far apart, so that the fat and tissue in the orbital septum are pulled to both sides, and 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. The other end of the guide rod (231) passes through a matching hole on the other operating part 22. The spring 232 is sleeved outside the guide rod 231, and its two ends are respectively connected to the two operating parts 22.

[0038] In this embodiment, the operating portion 22 extends toward the other side of the extension arm 12. Such a position design enables the operating portion 22 to be outside the patient's eye when applying external force, and a large operating space.

[0039] In this embodiment, the main hook 1 and the auxiliary hook 2 are both made of stainless steel, which is convenient for sterilization and disinfection.

[0040] Of course, the main retractor 1 and the auxiliary retractor 2 can also be made of other medical materials that are heat-resistant and have been sterilized.

[0041] As a preferred embodiment, the above-mentioned imaging system 3 is an optical fiber camera, and the imaging end of the imaging system 3 extends along one end of the extension arm 12 and approaches the main hook body 111.

[0042] In the above-mentioned embodiment, the optical fiber camera is arranged along the direction of the extension arm 12, its end (i.e., the imaging end) is close to the main hook body 111, and its optical fiber tail end is connected to the equipment and instruments.

[0043] In this embodiment, the imaging end of the above-mentioned optical fiber camera is provided with a light source. Through the light source, the light inside the orbital septum can be good during the operation, which is beneficial for the light camera to capture the picture of the internal environment of the orbital septum, the light in the surgical field of view is better, and the image quality is clearer.
