Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to an automatic retractor device for periorbital surgery. Background Art

[0002] From 2016 to 2020, the consumption of surgical projects in medical aesthetic surgery was mainly concentrated in facial plastic surgery, accounting for 24.74% of the consumption, of which rhinoplasty, eye surgery, and face lift accounted for 8.64%, 8.1%, and 8% respectively. According to the annual report released by the China Association of Plastic and Aesthetic Surgery, in 2022, the scale of China's plastic surgery market will reach 300 billion yuan. Due to the decline in the popularity of rhinoplasty, the periocular surgery market will occupy the largest market share in 2022.

[0003] At present, when performing lower eye bag surgery clinically, regardless of the incision of internal or external incision, an assistant is required to use an eye bag retractor (including double ball and flat retractor) to evert the upper eyelid or lower eyelid, thereby exposing the orbital septum fat of the upper eyelid or lower eyelid, and assisting the surgeon to obtain sufficient field of view to remove fat. To achieve this effect, two people are required to operate. If the assistant and the surgeon do not have a high degree of tacit understanding, and the angle or range of exposure of the upper or lower eyelid retraction cannot meet the surgeon's requirements, it will extend the unnecessary operation time, and in severe cases, it may cause: ① increased bleeding during surgery; ② insufficient hemostasis and postoperative congestion; ③ insufficient fat removal; ④ reduced patient comfort, and other problems. Therefore, there is a need for an eyelid retractor device that can be operated clinically. Publication No.: CN201520592445.3 provides an eye bag retractor solution, but the surgeon needs to hold the device for continuous migration without changing the operation. Publication No.: CN202023040533.2 provides a skin traction patch, but the traction direction of the skin is limited, and the individual differences of patients cannot meet the traction requirements of different surgical incisions. To this end, we propose an automatic retractor device for periocular surgery. Utility Model Content

[0023] The utility model is described in detail below in conjunction with the accompanying drawings.

[0024] As attached Figure 1 To Attachment Figure 5 As shown,

[0025] Embodiment 1:

[0026] An automatic retractor device for periocular surgery comprises a traction hook 1, an arc-shaped support joint 2 and a facial patch 3. The traction hook 1 is used to pull open the tissue structure of the patient's upper eyelid or lower eyelid to expose the surgical area. Specifically, a flat traction hook or a double-ball traction hook can be used. One end of the arc-shaped support joint 2 is connected to the traction hook 1, and the other end is provided with a traction belt 4. The middle convex part of the arc-shaped support joint 2 is pressed against the patient's face as a fulcrum to lift the end of one side close to the traction hook 1, so that the traction hook 1 is pulled at an inclined upward angle, so as to better realize the eversion of the tissue structure of the upper eyelid or lower eyelid; the end of the traction belt 4 is fixed on the facial patch 3.

[0027] Embodiment 2:

[0028] The facial patch 3 includes a bottom silicone gel 3-1, a fixing plate 3-2 and a pressing plate 3-3. The fixing plate 3-2 is adhered to the bottom silicone gel 3-1, the bottom silicone gel 3-1 is adhered to the patient's face, the pressing plate 3-3 is hinged at the top of the fixing plate 3-2, a card block 3-4 is provided on the fixing plate 3-2, a card slot 3-5 is provided on the pressing plate 3-3, a traction belt 4 is clamped between the fixing plate 3-2 and the pressing plate 3-3, and a pull ring 3-6 is also provided on the top of the pressing plate 3-3.

[0029] Embodiment 3:

[0030] The traction hook 1 is preferably made of non-heat-conductive and conductive materials to avoid contact with the electric knife during surgery and burns to the skin. The material can be plastic and is disposable.

[0031] The arc-shaped support joint 2 is preferably made of a bendable metal material, and its curvature is adjusted by manual bending. It should also be noted that the force required for bending should be greater than the force required for the traction hook 1 to pull open the tissue structure of the patient's upper eyelid or lower eyelid to avoid deformation of the arc-shaped support joint 2 during operation.

[0032] The surface of the traction belt 4 is rough so that it can be clamped by the pressing plate 3-3 and the fixing plate 3-2, and the width is 2mm.

[0033] Hook holes are provided at both ends of the arc-shaped supporting joint 2, and a hook-shaped structure is provided at the end of the traction hook 1 to connect to one of the hook holes at one end of the arc-shaped supporting joint 2. When it is necessary to replace or select a suitable traction hook 1, the traction hook 1 and the arc-shaped supporting joint 2 can be directly connected; the traction belt 4 is directly tied to or detachably connected to the hook hole at the other end of the arc-shaped supporting joint 2 through the hook lock 5.

[0034] In actual operation, the patient's face is disinfected and draped and the operation is planned first, then the above-mentioned components are connected, the periocular incision is made, the pull ring 3-6 is pulled to separate the card block 3-4 from the card slot 3-5 to open the fixed plate 3-2 and the pressing plate 3-3, the traction hook 1 is hooked under the patient's eyelid, the fixing angle is adjusted to a suitable open state, and the traction belt 4 is directly straightened and clamped in the appropriate position of the pressing plate 3-3 and the fixed plate 3-2. When the fixing angle needs to be readjusted, the pressing plate 3-3 is opened for adjustment.

[0035] Embodiment 4:

[0036] After the traction 4 is fixed, it may be necessary to fine-tune the degree of eyelid opening. For this purpose, a traction belt fine-tuning mechanism is designed to be arranged on the upper side of the fixed plate 3-2 close to the arc-shaped support joint 2. The traction belt fine-tuning mechanism includes a twisting shaft 6, a driving bolt 7 and a fixing nut 8. The two ends of the twisting shaft 6 rotate on two fixed seats 9. A horizontal wire groove 10 is provided on the twisting shaft 6. The traction belt 4 passes through the wire groove 10. A square slide groove 11 is provided in the center of the twisting shaft 6. A rectangular driving block 12 is slidably connected in the slide groove 11. The rectangular driving block 12 is fixedly connected to the tail of the driving bolt 7. The driving bolt 7 is threadedly connected to the fixing nut 8. The fixing seat 9 and the fixing nut 8 are arranged on the fixed plate 3-2.

[0037] The working principle is as follows: the driving bolt 7 is manually rotated, and the driving bolt 7 rotates and pushes forward linearly, driving the integrated rectangular driving block 12 to rotate and push linearly, and the rectangular driving block 12 rotates and drives the twisting shaft 6 to rotate, and the twisting shaft 6 retracts and releases the traction belt 4, thereby adjusting the tightness of the traction belt 4. The chute 11 can avoid motion interference caused by the linear push of the rectangular driving block 12.

[0038] Although the present invention has been disclosed as above in terms of preferred embodiments, they are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection defined by the claims of this application.
