[0042] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0043] Example 1

[0044] A specific embodiment of the utility model discloses a disposable sterile surgical sheet for debridement and suture of scalp trauma, such as Figure 1 As shown, it includes: a middle fitting pad 2 and an outer liquid-absorbing pad 1; the middle fitting pad 2 is made of gel or silicone material and can fit the human scalp; the fitting pad 2 is a ring-shaped structure, and the hollow part in the middle serves as the operation area; the liquid-absorbing pad 1 includes an upper water-absorbing layer and a lower waterproof layer; the liquid-absorbing pad 1 is arranged around the outer side of the fitting pad 2; the water-absorbing layer is used to absorb blood flowing out during the operation; the waterproof layer is a plastic waterproof film attached to the bottom of the water-absorbing layer, which is used to prevent liquid from seeping out of the water-absorbing layer.

[0045] Specifically, the material of the fitting pad 2 can be polyacrylate gel, which has strong viscosity and can be well fixed around the wound.

[0046] Specifically, the fitting pad 2 is a circular ring structure or a rectangular ring structure. When in use, the gel / silicone material has an adsorption effect. The gel material has good viscosity. The fitting pad 2 is fitted to the disinfected scalp, so that the sterile sheet can be firmly fixed around the wound to prevent the surgical sheet from sliding. At the same time, during the debridement process, it can prevent blood from flowing from the wound to the surrounding skin and affect the operation.

[0047] Furthermore, the bonding pad 2 adopts a gradient structure with a thin middle and thick edges. That is, the cross section of the bonding pad 2 is a triangle or a trapezoid.

[0048] In the utility model, after the annular fitting pad 2 fits the scalp, the blood stains on the surface of the surgical area can flow along the surface of the fitting pad to the water absorbing layer on the upper layer of the liquid absorbing pad 1 for absorption, thereby preventing the blood from affecting the surgical process or causing pollution.

[0049] Furthermore, the liquid-absorbing pad 1 is a rectangular pad; the water-absorbing layer is made of non-woven fabric or medical cotton pad.

[0050] Furthermore, there is a waterproof membrane under the water-absorbing layer, which is a plastic film, such as a polyethylene film, attached to the bottom surface of the water-absorbing layer. Due to the presence of the waterproof material, it can provide sufficient waterproof performance and reduce the risk of wound infection.

[0051] Furthermore, guide grooves are provided on the liquid-absorbing pad 1 and the bonding pad 2; the liquid on the surface of the bonding pad 2 is drained to the liquid-absorbing pad 1 through the guide grooves for absorption.

[0052] In order to adapt to the size of the surgical wound or the patient's body shape, in actual operation, medical staff can flexibly cut and use the sterile surgical sheet according to the size and shape of the wound to ensure that it can fit tightly around the wound and improve the efficiency and safety of the operation. Alternatively, the surgical sheet of the utility model can be set in a variety of sizes to meet different usage requirements.

[0053] The specific use steps of the sterile surgical sheet of the utility model are as follows:

[0054] (1) When a patient with scalp trauma comes to see a doctor, the skin is first prepared, the hair around the wound is removed, and then disinfection is performed. The disinfection area should be larger than the central hole area of ​​the designed sterile surgical sheet.

[0055] (2) After disinfection, cover the surgical area with a sterile sheet, align the central hole of the sterile surgical sheet with the wound, and try to make the wound located in the center of the hole. Fit the sticky gel area to the scalp below and press it tightly.

[0056] (3) During surgery, the gel of the sterile surgical sheet adheres closely to the skin tissue around the wound, preventing the sheet from slipping and pulling the surrounding hair into the surgical area, thereby reducing the risk of infection and making the surgical procedure smoother. The tight fit and sloped design of the gel pad prevent blood from easily flowing to other parts of the scalp during the debridement process, thus preventing discomfort caused by excessive blood remaining on the patient's scalp after surgery.

[0057] (4) After suturing, remove the sterile surgical drape. The gel design, unlike other adhesive tapes, reduces the pain of pulling hair when removing it.

[0058] The disposable sterile surgical sheet for scalp trauma debridement and suturing of this embodiment is composed of two major parts, the central area is a viscous gel area, and the peripheral material is divided into two layers, the lower part is a water-insulating material, and the surface is a water-absorbing material. The viscous gel material can make the sterile sheet well fixed, and the tight fit can reduce the blood flowing to the surrounding scalp during the debridement process. During the debridement process, the blood flows along the surface of the gel material to the surrounding water-absorbing material and is absorbed. Good fixation and smooth operation can also speed up the operation.

[0059] It is worth noting that the design and production process of the sterile surgical sheet of the present invention should comply with relevant medical disinfection standards to ensure its safety and reliability in clinical applications.

[0060] Example 2

[0061] A specific embodiment of the utility model improves the design of the sterile surgical sheet based on embodiment 1:

[0062] In this embodiment, Figure 2 , Figure 3 As shown, the absorbent pad 1 is provided with a first guide groove 101, and the fitting pad 2 is provided with a second guide groove 204; the first guide groove 101 and the second guide groove 204 are interconnected, and are used to drain the liquid at the fitting pad 2 to the absorbent pad 1 for absorption. This design can effectively absorb the blood produced by the wound, and prevent the blood from gathering on the surface of the fitting pad 2 or in the surgical area, which can not only speed up the operation, but also reduce the discomfort and pain of the patient.

[0063] like Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, the fitting pad 2 is a multi-piece splicing structure; a plurality of fan-shaped gel patches are connected in sequence and can be spliced ​​into a ring-shaped fitting pad.

[0064] Specifically, Figure 2 , Figure 3 , Figure 4As shown, the fitting pad 2 includes: a fixing hoop 201 and a plurality of fan-shaped patches 203; the fixing hoop 201 is bonded and fixed to the liquid-absorbing pad 1; the fixing hoop 201 is detachably connected to the fan-shaped patches 203, and the plurality of fan-shaped patches 203 can be assembled into an annular structure. In this embodiment, the annular fitting pad 2 is assembled in multiple pieces. For different human head shapes (different sizes and shapes), the gaps between the plurality of fan-shaped patches 203 can be deformed to a certain extent, reducing the entanglement of two adjacent fan-shaped patches 203, improving the fit between the fitting pad 2 and the head skin, preventing the surgical sheet from slipping, and ensuring the surgical effect.

[0065] Specifically, Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a plurality of positioning posts 202 are arranged at equal intervals on the fixing hoop 201; a positioning hole 205 is arranged on the edge of the fan-shaped patch 203, and the positioning posts 202 cooperate with the positioning holes 205 on the fan-shaped patch 203; a slit 206 connected to the positioning hole 205 is arranged on the outer side of the fan-shaped patch 203; when the fan-shaped patch 203 is torn, the positioning posts 202 can be pulled out from the slit 206, and then the fan-shaped patch 203 is separated from the fixing hoop 201. Since the gel material is a soft colloid with a certain elasticity, when the fan-shaped patch 203 needs to be torn off, the fan-shaped patch 203 is pulled outward to squeeze the positioning posts 202 out of the slit 206.

[0066] Considering that the wound of the patient may be long or irregular, in the case of emergency and other occasions where rapid surgery is required, in order to save the preparation time for surgery, the surgical sheet needs to be adjusted to a suitable size in time. In this embodiment, when the surgical area hollowed out in the middle of the surgical sheet is not enough to cover the surgical wound, one or two fan-shaped patches 203 can be quickly torn off, reducing the time for trimming the surgical sheet and facilitating rapid surgery.

[0067] It is worth noting that after the fan-shaped patch 203 is torn off, the bottom of the fixing hoop 201 can still fit the scalp to prevent liquid from leaking out. Preferably, the ratio of the width of the fixing hoop 201 to the width of the fan-shaped patch 203 is 0.5:1.

[0068] Furthermore, the positioning column 202 includes: a cylindrical section 202b and a spherical protrusion 202a provided at the end of the cylindrical section 202b; the cylindrical section 202b cooperates with the positioning hole 205. In this embodiment, a spherical protrusion 202a is provided at the end of the positioning column 202, and the diameter of the spherical protrusion 202a is larger than the diameter of the cylindrical section 202b, which can prevent the sector patch 203 from being accidentally separated from the fixing hoop 201, and ensure a good overall connection effect of the bonding pad 2.

[0069] like Figure 5 , Figure 6 Figure 7 , Figure 8 As shown, the fixing hoop 201 is provided with a step groove; the positioning column 202 is arranged on the step groove, and the bottom edge of the fan-shaped patch 203 is provided with a clamping portion 207, and the clamping portion 207 can be clamped with the step groove.

[0070] In this embodiment, by providing a fixing hoop 201 and a fan-shaped patch 203 at the connection point, a step groove and a snap-fitting portion are used to engage with each other, thereby ensuring the flatness of the bottom surface of the fitting pad 2, thereby achieving the fitting effect between the fitting pad 2 and the head skin, and ensuring reliable fixation of the surgical sheet.

[0071] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
