[0041] As attached Figure 5-7 As shown, attached Figure 5 -Attached Figure 7 The present invention is a front view, a top view and a bottom view of the flap pulling part of a flap retractor used in breast surgery in the embodiment of the present application. Specifically, the flap pulling assembly includes a rotating column 3021 and a pulling rod 3022 and a pulling plate 3023 in a "T" shape; an arc groove that slides with the rotating column 3021 is provided on the rotating disk 301; the pulling rod 3022 is connected to the lower end of the rotating column 3021, and the pulling plate 3023 is provided at the lower end of the pulling rod 3022. The rotating disk 301 is used to drive the contraction and expansion of the pulling plate 3023, so as to achieve the positioning of the surgical incision position of the patient and the pulling of the flap. In specific implementation, the rotating disk 301 rotates to drive the rotating column 3021 to move in the arc groove of the rotating disk 301, thereby driving the expansion and contraction of the pulling rod 3022 and the pulling plate 3023, and cooperating with the adjustment of the horizontal rod and the vertical rod of the adjustment part to move to the surgical incision position of the patient. In the embodiment of the present application, the turntable rotates, driving the rotating column to move in the arc-shaped groove of the turntable, thereby driving the expansion and contraction of the traction rod and the traction plate, and cooperating with the adjustment part to adjust the direction and angle of the traction part, and moving to the patient's surgical incision position, thereby positioning the patient's incision position and traction of the skin flap, achieving small-amplitude movement and traction, and accurate positioning.

[0042] As an embodiment, the traction rod 3022 and the traction plate 3023 are both inwardly curved structures. By setting the traction plate and the traction rod as inwardly curved structures, the traction of the skin flap can better adapt to the expansion and contraction of the traction plate in the direction of the breast skin texture, avoiding causing greater damage to the patient's skin.

[0043] As an implementation mode, a motor is provided at the end of the adjustment part, and a turntable is connected to the lower end of the motor. When the motor rotates, the turntable is driven to rotate in the reverse direction to contract the traction plate, and when the turntable rotates in the forward direction, the traction plate is expanded. The forward and reverse rotation of the turntable drives the expansion and contraction of the traction plate, thereby realizing the positioning of the surgical incision position of the patient and the traction of the skin flap, which saves manpower and is easy to use.

[0044] As an implementation method of this application, as shown in the attached Figure 8-9 As shown, attached Figure 8 FIG. 1 is a schematic diagram of the structure of a rotating disk of a skin flap retractor used in breast surgery according to an embodiment of the present application, and FIG. Fig. 9 The present invention is a schematic diagram of the structure of the groove plate of a skin flap retractor used in breast surgery in an embodiment of the present application. Specifically, a circular hole is provided in the center of the turntable 301, and an arc-shaped groove is provided on the turntable. The arc-shaped groove is used to slide with the rotating column to realize the expansion and contraction of the traction rod. A connecting shaft is provided on the central circular hole of the turntable 301 on the turntable. The lower end of the connecting shaft is connected to the groove plate, and the groove of the groove plate is adapted to the traction rod 3021. Specifically, when performing breast surgery, the turntable rotates to drive the rotating column 3021 to move in the arc-shaped groove of the turntable 301, thereby driving the traction plate 3022 to extend and retract in the groove plate, and cooperate with the adjustment of the horizontal bar and the vertical bar of the adjustment part to move to the patient's surgical incision position. In the embodiment of the present application, a groove plate is provided at the bottom of the turntable, and the traction plate extends and contracts in the groove plate as the rotating column moves, so that the position of the traction plate is more stable and accurate when extending and contracting, thereby ensuring the accurate positioning of the patient's incision position and the stability of the traction of the skin flap, achieving small-amplitude movement and traction, and at the same time improving the comfort of skin flap traction during breast surgery and reducing the patient's pain.

[0045] As attached Fig.10 As shown, attached Fig.10This is a schematic diagram of the specific structure of a traction plate of a skin flap retractor used in breast surgery in an embodiment of the present application. The traction rod 3022 is connected to the traction plate 3023 through an oscillator, and the oscillator is used to change the angle of the traction plate 3023. The setting of the oscillator allows the traction plate to swing and pull a certain amplitude along with the oscillator when the turntable drives the traction rod to expand and contract, thereby changing the angle of the traction hook on the traction plate, so that the traction hook hooks the skin flap tissue of the patient's incision and pulls it. Through the design of the oscillator, it is possible to effectively avoid human power from fixing the skin flap on the traction hook, relieve the pressure of surgical operation, help alleviate the patient's pain, and improve the safety of breast surgery.

[0046] As an implementation method, the pulling rod 3022 and the pulling plate 3023 are connected by a crank rocker 3024. The motor of the adjusting part rotates, driving the turntable to rotate, so that the rotating column moves in the arc groove of the turntable to achieve the expansion of the pulling plate. Since the pulling rod and the pulling plate are connected by the crank rocker, when the pulling plate is expanded, the crank rocker swings around the axis with the expansion of the pulling plate to a certain extent, so that the angle of the pulling hook on the pulling plate changes, hooking the flap tissue of the patient's incision to pull. Further, the motor is reversed to shrink the pulling plate, and the crank rocker swings around the axis with the expansion of the pulling plate to a certain extent, so that the angle of the pulling hook on the pulling plate changes, so that the pulling hook is separated from the flap.

[0047] As attached Fig.11 As shown, attached Fig.11 The internal structure diagram of the pulling plate of a skin flap retractor used in breast surgery in the embodiment of the present application is shown in FIG. The pulling plate 3023 is a "C"-shaped groove structure, and a retracting hook component is arranged in the "C"-shaped groove structure. Specifically, the retracting hook component includes a retracting hook plate 3027 and a plurality of retracting hooks 3025 arranged at intervals on the retracting hook plate. The retracting hook plate is located in the "C"-shaped groove structure. Through the design of the retracting hook plate.

[0048] As an implementation mode, the retraction hook component includes a retraction hook plate and a plurality of retraction hooks 3025 spaced apart on the retraction hook plate, and the retraction hook plate is located in a "C"-shaped groove structure. Specifically, the retraction hook component includes a retraction hook plate and a plurality of retraction hooks 3025 spaced apart on the retraction hook plate, and the retraction hook plate is located in a "C"-shaped groove structure. In specific implementation, the motor is rotated to drive the turntable to rotate, so that the rotating column 3021 moves in the arc-shaped groove on the turntable 301, driving the expansion of the retraction plate 3023, so that the retraction hook of the retraction hook member hooks the flap tissue to achieve the retraction of the flap. Preferably, three to five retraction hooks are provided on the retraction hook plate 3023. The provision of three to five retraction hooks is sufficient to complete the retraction of the flap at the incision position of the patient on the one hand, and on the other hand, the retraction hook achieves multi-point retraction, increases the contact area with the flap, and prevents the flap from being injured by one-point retraction.

[0049] As an implementation method, an elastic member 3026 is further provided between the "C"-shaped groove structure and the retracting hook member, and the elastic member is used to drive the retracting hook member to pop out and retract. Specifically, the elastic member can be a spring. Preferably, the spring coefficient of the spring is 1.5-3.9. A spring with a spring coefficient of 1.5-3.9 is used to ensure that when the spring pops out to realize the retraction and popping out of the retracting hook, it does not cause pulling and damage to the patient's skin flap, which is conducive to relieving the pressure of surgical operation, reducing the pain of the patient, and improving the safety of breast surgery.

[0050] As attached Fig.12 As shown, attached Fig.12 Schematic diagram of the structure of the retracting hook component in the embodiment of the present application. The retracting hook 3025 includes a hook handle 3028 and a hook rake 3029. The hook rake 3029 is arranged at the end of the hook handle 3028, and a row of hook teeth (3030) is provided on the hook rake 3029. By providing a row of hook teeth on the hook rake, on the one hand, the retracting hook design is prevented from damaging the patient's skin and tearing the skin flap; on the other hand, it is prevented from fixing the skin flap on the retracting hook by manpower, relieving the pressure of the surgical operation, which is conducive to alleviating the patient's pain and improving the safety of breast surgery.

[0051] As an implementation mode of the present application, a heating rod is provided on the inner wall of the "C"-shaped groove of the traction plate 3023. After the traction is completed, the retracted traction hook is heated at high temperature using the heating rod to achieve high-temperature disinfection of the traction hook, thereby ensuring hygiene and safety during the operation.

[0052] As an implementation method, as shown in the attached Fig. 9 As shown, a limiter is provided at the bottom of the "C"-shaped groove structure. The limiter is used to control the pop-up of the elastic member. On the one hand, it can adjust the pop-up and retraction of the traction hook to avoid long-term exposure of the traction hook, improve the safety and hygiene during the operation, and on the other hand, it limits the elastic member to improve the stability of the elastic member during the surgical operation. Specifically, the limiter adopts a contact limiter, which detects the extreme position of the flap traction and sends a signal through the contact with the flap during the movement of the traction part, so as to facilitate the pop-up movement of the elastic structure and ensure the safety during breast surgery. Common materials for limiters include silver-nickel alloy, cemented carbide, etc.

After the adjustment is completed, the handle 206 is pulled down to make it stuck in the corresponding arc groove on the gear to limit the crossbar 303. Finally, the motor on the crossbar 203 controls the rotation of the turntable 301, driving the flap pulling assembly 302 to move in the arc groove of the turntable 301, and then driving the expansion of the pulling rod 3022 and the pulling plate 3023 to pull the flap.
