DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Embodiment, a flushing bag for minimally invasive spinal surgery, includes a medical surgical film 3, a water diversion bag connected to the medical surgical film 3, and the medical surgical film 3 includes a surface protection film 1, a transparent water-absorbing gel layer 2, a film 3 and a base paper 4 arranged in sequence from top to bottom.

[0018] The solid matter of the transparent absorbent gel is composed of polyacrylic acid resin, sodium carboxymethyl cellulose and sodium polyacrylate. The design of the transparent absorbent gel layer 2 has the characteristics of rapid water absorption and water retention. Blood or effusion will be quickly absorbed by the gel and evenly distributed, and it is not easy to flow in strands on the surface of the gel. At the same time, the gel has good coagulation and high transparency.

[0019] The size of the base paper 4 is larger than the film 3 , so that the base paper 4 can be easily peeled off.

[0020] The upper end surface of the medical surgical film 3 except the water guide bag is provided with a water retaining strip 5, which includes a sponge strip 6 and a protective layer 7 wrapped around the outer surface of the sponge strip 6. The sponge strip 6 is harder than cotton and is not easy to collapse during long-term surgery. The sponge strip 6 is softer than plastic. During long-term surgery, if the medical staff put their hands on it, it will produce a certain amount of pressure and injure the medical staff.

[0021] A water pipe 8 is installed between the water retaining bar 5 and the medical surgical film 3. The water pipe 8 is connected and placed under the water retaining bar 5. The concealed design makes the whole look neat and tidy, and will not affect the operation of medical staff during surgery.

[0022] The water diversion pipe 8 in this patent is generally U-shaped and is set up through. This setting only needs to be connected to a water suction pump, which saves resources and is also convenient for handling. Then two water suction ports 9 are set on both sides of the surgical operation to absorb blood and water accumulation as quickly as possible when it comes out. Then the setting of the water diversion bag ensures that emergency treatment can be carried out even if the absorption is not timely, so that the blood and water accumulation can flow into the water diversion bag.

[0023] The water guide pipe 8 is provided with two water suction ports 9, and the inner wall 10 of the water suction port 9 is arranged in an inclined shape. The wall of the water suction port is thin and will not form any obstruction. For example, accumulated liquid or blood sometimes appears as small water droplets. When the water suction port 9 absorbs, due to the thickness of the wall of the water suction port 9, only the small water droplets in the upper half can be absorbed, and the lower half is blocked by the wall of the water suction port 9 and cannot enter the water guide pipe 8. The present device makes the wall of the water suction port 9 as thin as possible without affecting practicality, and can ensure that the blood and accumulated liquid are completely sucked into the pipe when absorbing water without forming any obstruction.

[0024] The terminal end of the water diversion pipe 8 is connected with a water suction pump.

[0025] The bottom end of the water diversion bag is provided with a drain nozzle 12, and the drain nozzle 12 is connected to a drainage valve 13 located in the water diversion bag.

[0026] A soft support frame 11 is provided around the water diversion bag.

[0027] Clinical application: First, the surgical site needs to be disinfected. After the skin is completely dry, unfold the medical surgical film 3 and stretch it to both sides, place it above the surgical port, tear off the basement membrane, and after the center is fixed, smooth the film 3 from the middle to the outside to make it completely in contact with the skin without leaving any bubbles. After completion, flatten the water bag. The soft support frame 11 is set so that the water bag will not fold. The soft support frame 11 at the bottom can be bent and connected to the operating table to keep it fixed. The water pipe 8 is aligned with both sides of the surgical center. After completing all the preliminary work, finally, according to the scale markings on the top of the film 3, the operation can be performed directly on the medical surgical film 3. After the operation, the film 3 can be slightly lifted on both sides for suturing.

[0028] This device adopts three methods to solve the problem that blood and fluid flowing out during surgery cannot be quickly cleaned up, thus affecting the operation of medical staff, and the problem that blood and fluid stay for too long and cause infection to patients. A layer of water-absorbing material is added to the medical surgical film 3. The setting of this material can absorb water. Rapid water absorption can effectively solve the situation of long-term surgery. The film 3 will not lack viscosity due to residual fluid, and then the accumulated fluid will enter between the medical surgical film 3 and the human body, causing infection and other problems. At the same time, the water pipe 8 is used to quickly absorb water to avoid the problem of blood and fluid accumulation under these two operations. The water bag is used to provide a bottom line. With the blessing of the three, the smooth operation of medical staff is guaranteed while also ensuring the health of patients.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
