[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-9 The present invention provides a technical solution: a surgical incision protection device, including a mounting frame 1, which reduces weight while ensuring strength, and avoids the patient's skin being compressed due to excessive weight during long-term surgery. The top of the mounting frame 1 has two mounting slots 2. A protective component 3 extending to the bottom of the mounting frame 1 is provided between the inner sides of the two mounting slots 2. An inflation component 4 is provided on the outer side of the protective component 3. A soft pad 7 is fixedly installed at the bottom of the mounting frame 1. A fixing mechanism 5 extending to the inner side of the mounting slots 2 and fitting with the protective component 3 is provided on the inner side of the mounting frame 1. A stabilizing mechanism 6 extending to the bottom of the protective component 3 is provided on the inner side of the mounting frame 1.

[0032] The protective component 3 includes a protective tube 31, which is located inside the mounting frame 1. The flexible material adapts to different tissue tensions, reducing mechanical damage to the incision. The hollow design provides space for instrument operation. Mounting plates 32 extending into the mounting groove 2 are fixedly installed on both sides of the protective tube 31. They cooperate with the limiting plate 52 of the fixing mechanism 5 and achieve quick fixation of the protective tube 31 through a snap-fit ​​structure, preventing the protective tube 31 from falling off due to changes in the patient's position during the operation. U-shaped plates 33 that fit against the top of the mounting frame 1 are fixedly installed on both the front and rear sides of the protective tube 31. The U-shaped structure wraps around the top edge of the mounting frame 1, and the anti-slip pad increases friction, preventing the protective tube 31 from rotating synchronously due to instrument operation, further ensuring stability. A mounting ring 34 is fixedly installed on the inner side of the protective tube 31. A transparent plate 35 that fits against the protective tube 31 is movably installed on the top of the mounting ring 34, providing an unobstructed surgical field of view, supporting endoscopic or direct visual operation, especially suitable for tissues that require fine separation, while avoiding interference from reflective baffles.

[0033] The mounting frame 1 has a circular hole inside, which is connected to the inner wall of the two mounting slots 2. The protective cylinder 31 is located inside the circular hole and extends to its bottom.

[0034] The inflation component 4 includes airbags 41. Four airbags 41 are fixedly installed on the outside of the protective cylinder 31. They form a ring-shaped expansion force through independent inflation, which distributes pressure more evenly than a single airbag, avoiding excessive stretching of local tissues and preventing tissue tearing caused by excessive stretching in one direction. Each airbag 41 inflates independently and automatically adjusts the expansion force according to the tissue elasticity to adapt to the differentiated expansion needs of different thicknesses (such as subcutaneous fat layer and muscle layer). A connecting tube 42 extending to the front of the airbag 41 is fixedly installed on the inner top wall of the airbag 41. An inflation device 43 is fixedly installed at the other end of the connecting tube 42. The pressure data inside the airbag 41 is fed back through the connecting tube 42. The pressure can be dynamically adjusted during the operation to adapt to changes in tissue state. The pressure value can be preset, and the airbag will automatically stop after inflating to the target value to prevent tissue tearing caused by over-inflation.

[0035] The inner side of the U-shaped plate 33 is equipped with an anti-slip pad, the two mounting plates 32 are symmetrically distributed from left to right, the four airbags 41 are evenly distributed, and the protective cylinder 31 is designed with a silicone composite structure. The flexibility of silicone conforms to the tissue around the incision, reducing mechanical friction on the incision when the instruments enter and exit, reducing the risk of postoperative infection. The hollow design forms a sterile operating space, avoiding direct contact between instruments and tissues outside the incision, which is in line with the principles of minimally invasive surgery.

[0036] The fixing mechanism 5 includes a mounting cavity 51. Two mounting cavities 51 are provided on the inner side of the mounting frame 1. The two mounting cavities 51 are located on opposite sides of the two mounting slots 2. A limiting plate 52 extending into the inner side of the mounting cavity 51 and abutting the top of the mounting plate 32 is slidably installed on the inner side of the mounting cavity 51. When the protective tube 31 is installed, the mounting plate 32 presses the inclined surface of the limiting plate 52 to make it move backward. After it is fully in place, the limiting plate 52 is reset under the action of the fixing spring 53, and locks the bottom of the mounting plate 32 to form a self-locking structure. A fixing spring 53 fixedly connected to the inner wall of the mounting cavity 51 is fixedly installed on one side of the limiting plate 52. A U-shaped block 54 extending to the top of the mounting frame 1 is fixedly installed on one side of the limiting plate 52. A push plate 55 is fixedly installed on the top of the U-shaped block 54. When the protective tube 31 needs to be removed after surgery, the push plate 55 is pushed to make the limiting plate 52 move backward and release the lock on the mounting plate 32.

[0037] The top of the limiting plate 52 is inclined, and the outer side of the push plate 55 is provided with an anti-slip sleeve. The rubber anti-slip sleeve increases friction and ensures that it can be operated with one hand. It is especially suitable for quick release devices in emergency situations. The top of the mounting frame 1 is provided with a limiting hole that matches the movement trajectory of the U-shaped block 54. The limiting hole is connected to the inner top wall of the mounting cavity 51.

[0038] The stabilizing mechanism 6 includes a mounting groove 601. The mounting groove 601 is located at the top left end of the mounting frame 1. A rectangular cavity 615 is located inside the mounting frame 1. A fixing rod 602 is fixedly mounted inside the mounting groove 601. A fixing ring 603 extending to the left side of the mounting groove 601 is movably mounted on the outside of the fixing rod 602. A fixing strap 604 extending to the right side of the mounting frame 1 is fixedly mounted at one end of the fixing ring 603, wrapping around the patient's body and tightening to fix the entire device to the surgical area, preventing the device from sliding due to the patient's breathing or positional changes. The length of the fixing strap 604 can be adjusted by a take-up drum 606 to accommodate patients of different body types. A rotating shaft 605 extending to the front side of the mounting frame 1 is rotatably connected to the rear side of the inner wall of the rectangular cavity 615. A take-up drum 606 is fixedly mounted on the outside of the rotating shaft 605. The other end of the fixing strap 604 extends to the inside of the rectangular cavity 615 and wraps around the outside of the take-up drum 606. The front end of the rotating shaft 605... A knob 607 is fixedly installed. A fixed frame 608 is fixedly installed on the inner bottom wall of the rectangular cavity 615. A lifting plate 609 is slidably installed on the inner side of the fixed frame 608. A U-shaped frame 610 extending to the top of the mounting frame 1 is fixedly installed on the top of the lifting plate 609. A return spring 611 fixedly connected to the inner top wall of the rectangular cavity 615 is fixedly installed on the top of the lifting plate 609. The return spring 611 pushes the lifting plate 609 upward, causing the locking plate 614 to re-engage in the slot. Prepare for the next fixation operation. A pressure plate 612 is fixedly installed on the top of the U-shaped frame 610. A chuck 613 located in front of the winding drum 606 is fixedly installed on the outside of the rotating shaft 605. A locking plate 614 that engages with the chuck 613 is fixedly installed on the top of the lifting plate 609. When the knob 607 is rotated to tighten the fixing belt 604, the locking plate 614 engages in the slot of the chuck 613, forming a mechanical self-locking mechanism to prevent the fixing belt 604 from loosening due to the weight of the device or the movement of the patient.

[0039] The outer side of the chuck 613 has a slot, the number of which can be set according to the needs and are distributed in a ring at equal intervals. The size of the slot is adapted to the chuck plate 614. The top of the mounting frame 1 has a through hole adapted to the U-shaped frame 610. The through hole is connected to the inner top wall of the rectangular cavity 615. The right side of the mounting frame 1 has a strip hole adapted to the fixing strap 604. The strip hole is connected to one side inner wall of the rectangular cavity 615. The top of the pressure plate 612 is provided with a sponge pad to distribute the local pressure when pressing and avoid finger fatigue caused by prolonged operation by medical staff. The outer side of the knob 607 is provided with a protective cover.

[0040] In use, insert the protective tube 31 into the round hole of the mounting frame 1, ensuring that the mounting plate 32 is fully inserted into the mounting groove 2, the U-shaped plate 33 fits against the top of the mounting frame 1, install the transparent plate 35 onto the mounting ring 34, check the clarity of the field of vision, connect the inflator 43 and the connecting tube 42 of the airbag 41, test whether the inflation function is normal, place the mounting frame 1 above the surgical incision, adjust the position so that the protective tube 31 is aligned with the center of the incision, gently press the protective tube 31 to make it fully in place, the limiting plate 52 automatically locks the mounting plate 32 under the action of the spring, and a "click" sound indicates that the locking is successful, tighten the fixing strap 604 and wrap it around the patient's body surface, insert the end of the fixing strap 604 into the rectangular cavity 615 and wrap it around the take-up drum. 606. Rotate knob 607 to tighten fixing strap 604 until the device is stable. Press pressure plate 612 to test if the self-locking function is normal. Start inflation device 43. Airbag 41 gradually inflates and evenly expands the incision tissue. Observe the degree of incision expansion through transparent plate 35. After reaching the target value, inflation device 43 automatically stops. Perform excision, sampling and other operations through the hollow channel of protective tube 31. Transparent plate 35 can be removed at any time to replace instruments or clear the field of vision. After the operation, press pressure plate 612 to disengage clamping plate 614 from clamping wheel 613. Rotate knob 607 to loosen fixing strap 604 and remove it. Push push plate 55 to retract limit plate 52. Lift protective tube 31 upward to remove it from mounting frame 1.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] In summary, this surgical incision protection device, through the setting of the fixing mechanism 5 and the top tilt design to achieve one-way locking, allows the protective cylinder 31 to be installed by squeezing the limiting plate 52 and retracting it. After it is fully in place, the limiting plate 52 is reset and locked by the fixing spring 53. After the operation, the limiting plate 52 is pushed by pushing the U-shaped block 54 to release the locking of the protective cylinder 31, which is easy to remove quickly and achieves the purpose of easy disassembly and cleaning. Through the setting of the stabilizing mechanism 6, after the winding drum 606 is tightened, the device is fixed to the patient's body surface as a whole, preventing the device from sliding due to changes in the patient's body position. After rotating the knob 607 to tighten the fixing band 604, the locking plate 614 is locked into the slot of the locking wheel 613 to form a self-locking. Pressing the pressure plate 612 makes the locking plate 614 disengage from the slot, which can quickly release the fixing band 604. This achieves the purpose of having a stabilizing structure and solves the problems of easy loosening and displacement of instruments during operation, the lack of a stabilizing structure affecting the use of the device, and the difficulty in cleaning the device due to its one-piece fixing structure, which may lead to bacterial growth from residual tissue.
