[0024] The surgical film is mainly designed for neurosurgery. It is used for the sterile covering step of the scalp after the neurosurgery draping and before the skin incision. Considering that the neurosurgery of the head belongs to strict sterile operation, slight pollution will lead to serious intracranial infection, which may endanger the life of the patient. After the head is disinfected and draped, the surgical wound is relatively spherical, and the overflow of the irrigation liquid during the operation easily leads to the wetting of the sterile drape and increases the incidence of central nervous system infection. The current neurosurgery surgical film has a large exosmosis liquid overflow after being applied, which may cause the sterile drape to be wet. The patent ingeniously designs the film flow guide strip, which is beneficial to complete adhesion and irrigation flow guidance during the operation and does not interfere with the operation. It can reduce the wetting of the sterile drape to a certain extent, and the film-storage bag integrated design focuses on reducing the incidence of intracranial infection during the operation. The surgical instrument bag on both sides of the storage bag is also beneficial to the placement and removal of surgical instruments during the operation, shortens the unnecessary search for surgical instruments, and to a certain extent, avoids the wetting and pollution of the surgical instruments by the irrigation liquid. From the perspective of the operator, this design is more humanized and beneficial to reducing the fatigue during the operation.

It is convenient to clean, disinfect or replace the surgical instrument storage bag 33 after the operation, and improves the flexibility and convenience of instrument storage management; different surgical instruments are placed in categories to improve the efficiency of taking surgical instruments.
[0041] Further, as shown in Figure 2 The surgical film 1 includes a three-layer structure, the middle layer is a sticky film 12, one side outer layer is a release film 13, and the other side outer layer is a film layer 11.
[0042] The three layers of the surgical film 1, the release film 13 plays a role in protecting the adhesion of the middle sticky film 12. In use, the release film 13 is peeled off to expose the sticky film 12, and the sticky film 12 is used to tightly adhere the film layer 11 to the skin surface of the surgical area. Ensure that the surgical film 1 is stably attached during the operation process and is not easy to shift or fall off, and can reliably receive surgical exudates; the release film design facilitates the operation of the surgical film 1 during preoperative storage and use.
[0043] Further, as shown in Figure 1 The back of the upper opening of the storage bag 3 is provided with a sticky layer 4, which is used to be attached to the surgical bed sheet and the skin surface of the surgical patient.
[0044] The sticky layer 4 on the back of the upper opening of the storage bag 3 can firmly adhere the storage bag 3 to the surgical bed sheet and the skin surface of the surgical patient by using the principle of sticking, achieving multidirectional fixation. Enhance the stability of the storage bag 3, prevent the storage bag 3 from shifting or falling off due to factors such as liquid gravity and instrument collision during the operation, and ensure that the exudate can flow smoothly into the storage bag 3.
[0045] Further, the cross section of the flow limiting strip 2 is circular, triangular or wedge-shaped, which is used to prevent the liquid components in the operation from overflowing to both sides, including blood, NaCl, water, H2O2 and iodophor.
[0046] The circular, triangular or wedge-shaped cross-section design of the flow limiting strip 2 effectively blocks various liquids in the operation from overflowing to both sides by changing the liquid flow path and resistance based on the principle of fluid mechanics, and guides the liquid to flow to the receiving bag 3 at the bottom of the surgical film 1. Precise control of the flow direction of surgical exudate prevents the spread of liquid outside the surgical area, maintains the cleanliness and dryness of the environment around the surgical area, and reduces the risk of surgical infection.
[0047] Further, the inside of the surgical instrument receiving small bag 33 is a rectangular surgical instrument placing cavity, and the inner wall is provided with a wear-resistant layer.
[0048] The inside of the surgical instrument receiving small bag 33 is a rectangular surgical instrument placing cavity, and the inner wall is provided with a wear-resistant layer. The wear-resistant layer uses the characteristics of wear-resistant materials to reduce damage caused by friction between the surgical instruments and the inner wall of the receiving bag 3. The surgical instruments are placed in order in the receiving small bag 33, which is convenient for quick retrieval; the wear-resistant layer prolongs the service life of the surgical instrument receiving small bag 33 and reduces the cost of frequent replacement.
[0049] Further, the top opening width of the receiving bag 3 is greater than the bottom width of the surgical film 1, and is made of a medical surgical film material.
[0050] The top opening width of the receiving bag 3 is greater than the bottom width of the surgical film 1, which can more comprehensively collect exudate flowing from the surgical film 1 based on the principle of expanding the collection range; the receiving bag 3 is made of a medical surgical film material, which meets the safety standards of medical supplies and has good biocompatibility and sanitary performance. Improve the exudate collection efficiency and avoid exudate overflow at the inlet of the receiving bag 3; ensure the safety of the use of the receiving bag 3 and will not cause adverse effects on the surgical patient.
[0051] The surgical film assembly with a surgical exudate backflow mechanism of the utility model in use, first, the medical staff peels off the release film 13 of the surgical film 1, exposes the middle part of the adhesive film 12, covers the film layer 11 on the skin of the surgical area accurately, uses the adhesion of the adhesive film 12 to make the surgical film 1 closely adhere, avoids the appearance of wrinkles or displacement. By opening the adhesive film 12 to expose the part needing operation, the operation is carried out. Then, through the adhesive layer 4 on the back of the upper opening of the receiving bag 3, the receiving bag 3 is firmly adhered to the surgical bed sheet and the skin surface of the patient, to ensure that the top opening of the receiving bag 3 is aligned with the bottom of the surgical film 1, and because the top opening width of the receiving bag 3 is greater than the bottom width of the surgical film 1, it can comprehensively collect the liquid flowing from the surgical film 1. At the same time, according to the type of surgical instruments required, the surgical instrument receiving small bag 33 is installed on the inside of the inner bag 32 on both sides.
[0052] The exosmosis liquid such as blood water, NaCl solution, H2O2, iodophor and the like generated in the operation process falls on the operation film 1, and under the blocking effect of the flow limiting strips 2 vertically installed on both sides of the operation film 1 and having a circular, triangular or wedge-shaped cross section, the exosmosis liquid cannot overflow to both sides, but can only flow along the operation film 1 to the bottom of the storage bag 3. When the exosmosis liquid flows into the inner bag 32, the liquid such as blood water passes through the blood water filter screen 321 at the bottom of the inner bag 32 to enter the outer bag 31 for centralized collection, and the solid impurities are filtered on the blood water filter screen 321, so that the solid-liquid preliminary separation is realized. When the bipolar electrocoagulation, monopolar electric blade and the like operation instruments need to be temporarily placed, the medical staff places the instruments from the storage opening 331 at the top of the operation instrument storage small bag 33, the blood water attached to the surface of the instruments can leak out to the inner bag 32 through the protective screen 332 at the bottom, since the pore diameter of the protective screen 332 is smaller than the minimum width of the operation instruments, the instruments will not fall off, and the rectangular placement cavity and the inner wall wear-resistant layer in the operation instrument storage small bag 33 can ensure that the instruments are placed in order and the abrasion is reduced.
[0053] The postoperative treatment stage: after the operation is completed, the medical staff first takes out the operation instruments from the operation instrument storage small bag 33 for cleaning and disinfection. Then, the operation instrument storage small bag 33 is detached from the inner wall of the inner bag 32 through the adhesive strip or the tear strip, and is cleaned, disinfected or replaced separately. Then, the accumulated liquid in the storage bag 3 is treated, the liquid such as blood water in the outer bag 31 is treated according to the medical waste treatment standard, the solid impurities on the blood water filter screen 321 in the inner bag 32 are cleaned. Finally, the operation film 1 and the storage bag 3 are removed, and the use process of the whole operation film assembly is completed.
