Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a surgical incision protection device. Background Technology

[0002] In the field of clinical surgery, preventing surgical site infection, avoiding postoperative recurrence and metastasis of malignant tumors, minimizing surgical trauma, and promoting wound healing have always been critical issues of utmost concern to surgeons. Currently, cotton gauze is the most commonly used material for protecting surgical wounds in many surgical procedures both domestically and internationally. However, this traditional cotton gauze has several significant drawbacks: it is easily soaked by water, blood, pus, and exudate (which may contain tumor cells), greatly increasing the risk of postoperative surgical site infection. Especially during malignant tumor surgery, when the tumor is removed, tumor cells are highly likely to detach and contaminate the surgical wound, leading to serious consequences such as tumor implantation recurrence and metastasis at the surgical wound site.

[0003] In addition, surgeons have always faced a difficult challenge: minimizing the size of the surgical incision while ensuring sufficient exposure of the surgical field for smooth and convenient surgical procedures. Current surgical practice typically involves either directly using retractors to pull muscle tissue or using a gauze pad as a barrier. However, both methods have significant drawbacks: direct muscle pulling can lead to muscle damage, and prolonged exposure of the surgical incision to air often results in dryness, degeneration, and even necrosis of the soft tissue, undoubtedly increasing the risk of delayed wound healing, infection, and soft tissue damage, severely hindering wound healing; while using a gauze pad, due to the difficulty in maintaining even pulling force, often results in gauze wrinkles and slippage, severely affecting the clarity and stability of the surgical field and causing numerous inconveniences to the surgical procedure. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a surgical incision protection device that is simple in structure, easy to operate, and inexpensive. This device isolates the surgical field from the soft tissues around the incision, protects the wound, prevents postoperative infection and wound seed metastasis, thereby improving the safety and quality of surgery, accelerating patient recovery, and enhancing prognosis.

[0005] To achieve the above objectives, the present invention provides a surgical incision protection device, comprising an incision protection medium and a TPU film fixed to the back of the incision protection medium; the top of the incision protection medium is provided with a water inlet pipe, and the lower edge of the water inlet pipe is provided with a seepage hole for allowing external liquid to permeate into the incision protection medium to keep it moist; the bottom of the incision protection medium is provided with a water outlet pipe, and the upper and lower edges of the water outlet pipe are provided with suction holes for draining liquid around the surgical incision; the incision protection medium is made of cotton wool or double-layer gauze.

[0006] Preferably, the inlet pipe and the outlet pipe are respectively installed inside the top and bottom of the cut protection medium.

[0007] Preferably, the cut protection medium and the TPU film are tightly bonded together.

[0008] Preferably, the incision protection medium and the TPU film are further sutured together with sutures.

[0009] Preferably, the TPU film is fixed with steel wire supports at corresponding positions at the top and bottom of the cut protection medium for support.

[0010] Preferably, the wire support is further connected to the TPU film via a stitch.

[0011] Preferably, the water outlet pipe can be connected to a negative pressure suction device.

[0012] Preferably, the thickness of the cut protection medium is 2.0 mm, and it is soft, smooth, and tough; the thickness of the TPU film is 0.5 mm, and its smooth side faces the cut.

[0013] Preferably, the inner diameter of both the inlet pipe and the outlet pipe is 0.5 mm; the diameter of the seepage hole is 0.2 mm.

[0014] Preferably, the diameter of the wire support is 2.0 mm.

[0015] The beneficial effects of this novel surgical incision protection device in clinical application are reflected in the following aspects:

[0016] This invention effectively improves the safety, effectiveness, and postoperative recovery quality of surgery. The device completely isolates the surgical field from the surrounding soft tissue of the surgical incision, preventing contamination of the incision by air, blood, and exudate (containing tumor cells), thereby preventing postoperative infection and wound metastasis during malignant tumor surgery, providing reliable safety for patients. Simultaneously, cotton wool or double-layered gauze combined with an intravenous infusion line continuously moistens the wound, preventing tissue dryness, promoting wound healing, reducing wound complications caused by dryness, and improving the speed and quality of wound recovery.

[0017] Furthermore, the smooth surface of the TPU film within the incision fully exposes the surgical field, while the built-in upper and lower steel wire frames effectively extend and stabilize this incision protection device. This solves the problem of unclear vision caused by wrinkles and slippage in traditional gauze, providing surgeons with a clear and stable surgical field, making surgical operations more convenient and precise, and improving the success rate and safety of the surgery. The cotton wool or double-layered gauze is smooth, tough, and soft, closely conforming to the incision tissue, reducing friction and traction damage to incision tissues (such as blood vessels and adipose tissue). It plays a particularly important protective role for fragile blood vessels and poorly resistant adipose tissue, reducing the risk of intraoperative tissue damage and maintaining the integrity and function of the incision tissue.

[0018] In terms of structural design, this invention features easy insertion into the incision and simple operation, allowing medical staff to quickly and skillfully install and adjust it, saving surgical time and improving surgical efficiency. Furthermore, different specifications of surgical incision protection devices can be selected according to the size of the incision, offering strong flexibility and wide applicability to meet the protection needs of different surgical incision locations and types, providing greater convenience for clinical surgery. Simultaneously, the materials used in this device are readily available, requiring no special or expensive raw materials. Its simple structural design allows for manufacturing without complex processes, reducing production costs and medical expenses, and it has good prospects for widespread application, providing more patients with economical and effective surgical incision protection.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] This utility model discloses a surgical incision protection device, designed to solve the problem of isolating the surgical field from the surrounding soft tissue during surgery, preventing postoperative infection and wound seed metastasis, while keeping the incision moist to promote healing and reduce tissue damage. The device has a simple structure, uses readily available materials, and has low manufacturing costs, showing promising clinical application prospects.

[0026] The surgical incision protection device of this utility model mainly includes a brain cotton 4. The inner top and inner bottom sides of the brain cotton 4 are respectively provided with a water inlet pipe 1 and a water outlet pipe 2. A TPU film 6 (thermoplastic polyurethane) is provided on the back of the brain cotton 4. The TPU film 6 extends from the back of the top of the brain cotton 4 to the back of the bottom of the brain cotton 4. The TPU film 6 embeds a steel wire support 3 on both the back of the top and the back of the bottom of the brain cotton 4.

[0027] The diameter of the steel wire support 3 is 2.0mm, and its shape is adapted to the back of the top and bottom of the brain cotton 4. After the steel wire support 3 is embedded in the TPU film 6, it is further sewn to the TPU film 6 (thermoplastic polyurethane) by the suture line 8 to achieve a firm connection and ensure the support effect of the steel wire support 3.

[0028] The inlet tube 1 is sutured to the top of the brain cotton 4. The lower edge of the inlet tube 1 has a drainage hole 5, which allows the liquid delivered by the external infusion tubing to permeate evenly into the brain cotton 4, thus keeping the brain cotton 4 moist, preventing the incision tissue from drying out, and providing a good moist environment for surgical procedures. The outlet tube 2 is sutured to the bottom of the brain cotton 4. Both the upper and lower edges of the outlet tube 2 have suction holes 5, which can be connected to a negative pressure suction device. This allows for the timely suction and drainage of fluids (such as blood, exudate, etc.) around the surgical incision 7, maintaining a clear surgical field, facilitating surgical procedures, and preventing harmful substances (such as tumor cells) in the fluid from contaminating the incision, reducing the risk of postoperative infection and wound implantation metastasis during malignant tumor surgery.

[0029] A TPU film 6 covers the inner side of the incision (the side away from soft tissue) of the brain cotton 4. The two are tightly bonded together and further mechanically sutured together by sutures 8 to ensure a strong connection. The brain cotton 4 has a certain thickness (2.0 mm), is soft, smooth, and tough, and can closely adhere to the soft tissue, reducing friction and traction damage to incision tissues (such as blood vessels and adipose tissue), effectively protecting fragile tissues, and providing stable isolation for surgical operations. The TPU film 6 is 0.5 mm thick, has good flexibility and smoothness, and its smooth side faces the incision (i.e., away from soft tissue), which can completely isolate the surgery from the soft tissue around the incision, solving the problem of unclear vision caused by wrinkles and slippage of traditional gauze, making the surgical operation more convenient and precise.

[0030] Both the inlet pipe 1 and the outlet pipe 2 have an inner diameter of 0.5mm, which meets the requirements for liquid delivery and suction. The seepage hole 5 of the inlet pipe 1 has a diameter of 0.2mm, which allows the liquid to permeate evenly into the cotton wool 4, ensuring the uniformity of the cotton wool 4's moisture content and avoiding localized over-wetting or under-wetting. The suction hole of the outlet pipe 2 works in conjunction with the negative pressure suction device, allowing for flexible adjustment of the water inlet speed and negative pressure suction according to the moisture content of the incision, achieving precise control of the liquid around the incision.

[0031] In practical applications, the operation method of this surgical incision protection device is described as follows:

[0032] 1) Disinfect the skin of the 7 parts of the surgical incision and cover them with a sterile surgical drape;

[0033] 2) Cut through the skin, subcutaneous tissue, and muscle layer by layer until you reach the tissue that needs to be treated deep inside the incision, such as bone or abdominal organs;

[0034] 3) Connect the inlet pipe 1 to the infusion pipeline and the outlet pipe 2 to the negative pressure suction device to ensure the normal operation of the device so that the soft tissue around the surgical incision 7 is always kept moist.

[0035] 4) The surgical incision protection device 4 is applied to the soft tissue around the incision. The lower wire support 3 extends deep into the incision, and the upper wire support 3 is temporarily sutured and fixed to the skin surface on the outside of the incision with suture thread. The incision protection device is effectively supported and fixed by the upper and lower wire supports. The smooth surface of the TPU film 6 exposes the surgical field, thereby completely isolating the surgical field from the soft tissue around the incision.

[0036] During the operation, the moistened brain cotton 4 can easily adhere to the soft tissue, and the incision edge and incision protection device can be sutured during the operation as needed to further enhance the fixation effect of the device.

[0037] This novel surgical incision protection device combines multiple functions of isolation, moisturizing, and support. It completely isolates the surgical field from the soft tissue surrounding the surgical incision 7, effectively preventing contamination of the incision by air, blood, and exudate (including tumor cells), thus reducing the risk of delayed healing and infection after surgery. The brain cotton 4, combined with the infusion tubing, continuously moistens the wound, maintaining its moisture and promoting healing. Simultaneously, the smooth surface of the TPU film 6 provides a clear view for surgical procedures, reducing tissue damage and improving patient prognosis. Furthermore, this invention features easy insertion into the incision and simple operation, allowing for flexible selection based on incision size. It requires no complex processes, has low manufacturing costs, and is suitable for widespread clinical application.

[0038] Example 2:

[0039] This embodiment discloses a surgical incision protection device, whose structure and function are basically the same as those of Embodiment 1. The difference between this embodiment and Embodiment 1 is that this embodiment uses double-layer gauze with a total thickness of 2mm instead of brain cotton 4.

[0040] Specifically, the inlet pipe 1 and outlet pipe 2 are located on the top and bottom inner sides of the double-layer gauze, respectively, and are sewn between the two layers of gauze. A TPU film 6 is also provided on the back of the double-layer gauze, extending from the top back to the bottom back, and a wire support 3 is embedded in both the top and bottom backs. The shape of the support 3 matches the top and bottom backs of the double-layer gauze, and it is sewn to the TPU film 6 with stitches 8 to ensure a secure connection.

[0041] In practical applications, the operation method of the surgical incision protection device in this embodiment is the same as that in embodiment 1. It can effectively solve the problem of isolation between the surgical field and the soft tissue around the incision during the operation, prevent postoperative infection and wound seeding metastasis, and at the same time keep the incision moist, promote healing, and reduce tissue damage.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
