Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a breast cancer surgery device capable of realizing incision expansion. Background Art

[0002] In breast cancer surgery, incision expansion is usually achieved through the use of expanders, which are implanted in the cavity under the chest skin immediately after the breast tissue is removed and perform initial expansion during surgery to allow the reconstruction process to begin immediately after surgery.

[0003] After searching the Chinese patent with the announcement number CN211022822U, a breast cancer surgical device capable of expanding the incision is disclosed, wherein the front and rear ends of the elliptical push plate are in contact with the front push rod and the rear push rod respectively, the left ends of the front push rod and the rear push rod are fixedly connected with the left stretching arm provided at both ends of the left tensioner through the front push rod and the left rear fixed column respectively, and the right ends of the front push rod and the rear push rod are fixedly connected with the right stretching arm provided at both ends of the right tensioner through the right front fixed column and the right rear fixed column respectively, and then the expansion function of the incision during surgery can be realized by rotating the elliptical push plate to push the front push rod and the rear push rod.

[0004] Based on the above search and combined with the existing technology, it was found that: when an elliptical push plate is used to expand the surgical incision, the elliptical push plate cannot fit the inside of the surgical incision and the expansion effect is poor. When a circular expansion bag is used to expand the incision, the volume of the expansion bag changes when it is filled with saline, and the change speed and volume of the top and bottom of the expansion bag, as well as the height change of the expansion bag cannot be controlled independently, resulting in the inability to meet the patient's real-time expansion needs of the incision.

[0035] Working principle: During breast cancer surgery, when the incision needs to be expanded, the motor 1 5 on the incision expansion bracket 2 is started, and the one-way screw 3 rotates, thereby controlling the lifting plate 8 to descend. The top expansion capsule 11, the bottom expansion capsule 12 and the telescopic capsule 18 connected to the liquid inlet pipe 10 at the bottom of the lifting plate 8 are placed in the incision of the breast cancer, and saline is injected according to the expansion demand. The saline injection pump 6 heats the saline in the liquid storage tank 4 to a temperature close to that of the human body and delivers it to the movable tube 16 through the hose 7. During the initial expansion, the motor 2 13 is started, so that the rotating rod 20 drives the gear 1 15 to rotate, thereby driving the movable tube 16 to rotate through the meshing gear 2 24, and the rectangular bottom of the movable tube 16 The hole 27 is first aligned with the three holes 24 31 on the liquid inlet tube 10, and the incoming physiological saline enters the top expansion capsule 11, the bottom expansion capsule 12 and the telescopic capsule 18 at the same time. The volume of the top expansion capsule 11 and the bottom expansion capsule 12 increases to initially expand the incision, and the telescopic capsule 18 is telescoped to adjust the height, so that the top expansion capsule 11 and the bottom expansion capsule 12 are close to the top and bottom of the incision, the bottom expansion capsule 12 is disc-shaped to stably support the bottom, and the top of the top expansion capsule 11 is arc-shaped to adapt to the incision for stable expansion. Then, the movable tube 16 is rotated according to the incision expansion requirements of the real-time operation, and the pressure sensor 26 is set in the top expansion capsule 11 and the bottom expansion capsule 12 to cooperate with data acquisition. The module, the signal processing unit 14 and the display interface understand the pressure value. When the pressure value of the corresponding pressure sensor 26 is low, it means that the expansion force of the top or bottom of the incision needs to be increased, that is, the top expansion capsule 11 or the bottom expansion capsule 12 needs to continue to be injected with saline. The rotation of the movable tube 16 will align the rectangular hole 27 with the second hole 29 or the third hole 30 respectively. When the rectangular hole 27 is aligned with the second hole 29, the bottom expansion capsule 12 is injected with saline. The bottom expansion capsule 12 expands to increase the expansion area of ​​the bottom of the combined capsule. When the rectangular hole 27 is aligned with the third hole 30, the top expansion capsule 11 is injected with saline. The top expansion capsule 11 expands to increase the expansion area of ​​the top of the combined capsule. When it is aligned with the first hole 28, it is retracted. As the height of the capsule 18 increases, the vertical expansion of the incision increases synchronously. When the pressure sensor 26 reaches a dangerous value, the medical staff suspends the injection of saline solution, and continues the injection after the skin of the incision expansion adapts and the value measured by the pressure sensor 26 decreases. The annular frame 17 is moved up and down on the outside of the incision. The annular frame 17 is connected to the limit by the telescopic rod 36. After adjusting to the appropriate height, the telescopic rod 36 is fixed by the locking knob. The support rods 21 arranged on both sides of the annular frame 17 cooperate with the spring 22 and the positioning pad 23 to press the outside of the incision. When the incision expands under the action of the internal combined capsule, the outer wall positioning pad 23 presses it, thereby improving the stability of the incision expansion structure and preventing the expansion structure from shifting.

[0036] A mark is set on the annular frame 17, and a slide groove is set on the movable tube 16. A pointer 25 is slidably connected in the slide groove. According to the pointer 25 and the mark, it is convenient to determine which part of the combined capsule to inject saline. When the annular frame 17 is raised or lowered, the pointer 25 also slides and rises in the slide groove to ensure that the pointer 25 is always slidably connected to the outer wall of the top of the annular frame 17. A lamp holder and an illuminating lamp 32 are set at the bottom of the annular frame 17 to illuminate the expanded incision. The movable tube 16 and the saline injection pump 6 are connected by a hose 7. The positioning pad 23 is set in an arc shape and tilted. A sponge pad is also set at the bottom to buffer the pressure on the skin when pressing.

[0037] A rack 19 is provided at the bottom of the lifting plate 8. When the lifting plate 8 is lowered, the meshing gear 33 drives the bidirectional multi-threaded screw 34 to rotate, thereby driving the two protective covers 9 to separate. The bidirectional multi-threaded screw 34 is provided with multiple threads to ensure that the rotation of the bidirectional multi-threaded screw 34 can drive the protective cover 9 to move a required distance, exposing the top expansion capsule 11, the bottom expansion capsule 12 and the telescopic capsule 18. After the incision expansion is completed, when the physiological saline is recovered from the liquid storage tank 4, the combined capsule shrinks to reduce the volume, and the motor 15 controls the lifting plate 8 to reset and rise to a certain height, and the combined capsule is slowly Remove it, clean and dry it, and then continue to control the lifting plate 8 to rise until it is completely reset. During the rising process of the lifting plate 8, the rack 19 will also drive the two-way multi-threaded screw 34 to rotate in the opposite direction through the gear three 33. The protective cover 9 gradually approaches the spliced ​​box body to protect the combined capsule, prevent it from being affected by external factors and improve the structural safety. The height of the box body composed of the protective cover 9 is higher than the height of the combined capsule, and is adapted to the size of the positioning pad 23 to ensure that the combined capsule can be safely lowered inside the protective cover 9 when the protective cover 9 is just separated, and the positioning pad 23 will not form a barrier to the protective cover 9.
