[0002] Surgical incision infection is the most common complication after surgery. To prevent surgical incision infection, there are many clinical measures, such as carefully disinfecting and cleaning the incision site before surgery and paying attention to the cleanliness of the incision after surgery. Through a large number of clinical controlled studies, it has been proved that an incision protection sheath (also known as a disposable incision retractor and fixator) can significantly reduce the incidence of surgical incision infection. For tumor diseases, the incision protection sheath can prevent the tumor specimen from being transferred to the incision when taken out of the patient's body.

[0003] Existing incision protection sheaths are made of soft materials and may deform due to skin tension during the use of some surgical procedures, thus affecting the surgical effect. Utility Model Content

[0004] The objectives of this application include, for example, providing an incision protection sheath that can, to a certain extent, prevent the incision protection sheath from deforming and thus improve the surgical effect.

[0005] The embodiments of this application can be implemented as follows:

[0006] The embodiments of this application provide an incision protection sheath, which includes a first ring body, a second ring body, and a membrane body connected between the first ring body and the second ring body. A channel is formed among the first ring body, the membrane body, and the second ring body. A support ring body for supporting the first ring body is provided inside the first ring body.

[0007] Optionally, the support ring body coincides with the central axis of the first ring body. In any cross-section along the circumferential direction of the first ring body, the cross-sections of the support ring body and the first ring body are both circular, and the support ring body and the first ring body are concentrically arranged.

[0008] Optionally, an annular through-hole is formed along the circumferential direction of the inside of the first ring body, and the support ring body is arranged in the annular through-hole.

[0027] It should be noted that the features in the embodiments of this application can be combined with each other without conflict.

[0028] Surgical site infection, also known as SSI (Surgical Site Infection), is the most common complication after surgery. To prevent SSI, there are many clinical measures, such as carefully disinfecting and cleaning the incision site before surgery and paying attention to the cleanliness of the incision after surgery. Through a large number of clinical controlled studies, it has been proved that the incision protection sleeve can significantly reduce the incidence of SSI. And for tumor diseases, the incision protection sleeve can prevent the tumor specimen from being transferred to the incision when taken out of the patient's body. Among them, the incision protection sleeve is also called a disposable incision retractor and fixator.

[0029] The inventors of the present application have found that the existing incision protection sheath is made of a soft material, and during the use of some surgical procedures, the outer ring may deform due to the tension of the patient's skin, thus affecting the surgical effect. Moreover, in some cases, due to surgical requirements, the film in the middle of the incision protection sheath needs to be adjusted by inverting it inward through the outer ring. This action requires a large external force to completely invert the outer ring, and the larger the diameter of the outer ring, the greater the difficulty of inversion, which in turn affects the normal use of doctors. The embodiments of the present application provide an incision protection sheath that solves at least the above technical problems.

[0030] Please refer to Figures 1 - 3 , Figure 1 which is a schematic structural diagram of the incision protection sheath from the first perspective in the embodiment of the present application; Figure 2 which is a partial structural schematic diagram of the incision protection sheath in the embodiment of the present application; Figure 3 which is a schematic structural diagram of the incision protection sheath from the second perspective in the embodiment of the present application.

[0031] The incision protection sheath provided by the embodiment of the present application includes a first ring body 1, a second ring body 2, and a film body 3 connected between the first ring body 1 and the second ring body 2. A channel 4 is formed among the first ring body 1, the film body 3, and the second ring body 2. The first ring body 1 is used to be placed outside the patient's body, and the second ring body 2 is used to be placed inside the patient's body; a support ring body 11 for supporting the first ring body 1 is arranged inside the first ring body 1; the support ring body 11 coincides with the central axis of the first ring body 1, that is, the support ring body 11 and the first ring body 1 are coaxially arranged.

[0032] It should be noted that the film body 3 is generally in a cylindrical shape. The film body 3 has a relative first annular opening and a second annular opening. The periphery of the first annular opening is butted against the first ring body 1, and the periphery of the second annular opening is butted against the second ring body 2, so that a channel 4 is formed among the first ring body 1, the film body 3, and the second ring body 2, so that the doctor can perform the operation through the channel 4; the outer ring corresponds to the first ring body 1 in this embodiment.

[0033] In an alternative embodiment, the first ring body 1, the second ring body 2, and the support ring body 11 are all circular rings. Of course, in other embodiments, the shapes of the first ring body 1, the second ring body 2, and the support ring body 11 are not limited to circular rings, and may also be elliptical, square, etc.

[0034] During the process of using the incision protector, the first ring body 1 is placed outside the patient's body, the second ring body 2 is placed inside the patient's body, and the membrane body 3 is connected between the first ring body 1 and the second ring body 2 to form a channel 4 through which the doctor performs the operation. Since the support ring body 11 that supports the first ring body 1 is provided inside the first ring body 1, the first ring body 1 is not easily deformed, and the first ring body 1 is more easily folded inward under the support of the support ring body 11, thus avoiding deformation of the first ring body 1 to a certain extent and reducing the difficulty of folding the first ring body 1.

[0035] In an alternative embodiment, in any cross-section along the circumferential direction of the first ring body 1, the cross-sections of the support ring body 11 and the first ring body 1 are both circular, and the support ring body 11 and the first ring body 1 are concentrically arranged.

[0036] It should be noted that in any cross-section along the circumferential direction of the first ring body 1, the cross-sections of the support ring body 11 and the first ring body 1 are both circular, and the support ring body 11 and the first ring body 1 are concentrically arranged, indicating that the support ring body 11 is located in the middle position of the first ring body 1, so as to provide a relatively balanced support effect in all directions of the first ring body 1.

[0037] In an alternative embodiment, an annular through-hole is formed along the circumferential direction of the first ring body 1 inside the first ring body 1, and the support ring body 11 is arranged in the annular through-hole.

[0038] It should be noted that in any cross-section along the circumferential direction of the first ring body 1, the cross-section of the annular through-hole is also circular, and the support ring body 11 is arranged in the annular through-hole; the cross-sectional diameter of the support ring body 11 is greater than or equal to the cross-sectional diameter of the annular through-hole, so that the support ring body 11 always extrudes the hole wall of the annular through-hole outward, the support ring body 11 and the first ring body 1 are relatively fixed, and the support ring body 11 can support the first ring body 1.

[0039] In an alternative embodiment, both the first ring body 1 and the second ring body 2 are connected to the membrane body 3 by heat sealing.

[0040] It should be noted that the principle of heat sealing is to heat the material to above the melting point using heat energy to make it soft, and then apply pressure to firmly connect two or more components together.

[0041] The first ring body 1 is connected to the membrane body 3 by heat sealing, that is, the periphery of the first annular opening is connected to the first ring body 1 by heat sealing, which can provide a better fixing effect between the first ring body 1 and the membrane body 3, making it difficult for the first ring body 1 and the membrane body 3 to separate; the second ring body 2 is connected to the membrane body 3 by heat sealing, that is, the periphery of the second annular opening is connected to the second ring body 2 by heat sealing, which can provide a better fixing effect between the second ring body 2 and the membrane body 3, making it difficult for the second ring body 2 and the membrane body 3 to separate.

[0042] When the periphery of the first annular opening is connected to the first annular body 1 by heat sealing, and the periphery of the second annular opening is connected to the second annular body 2 by heat sealing, a channel 4 is formed between the first annular body 1, the membrane body 3 and the second annular body 2, so that the doctor can perform surgery through the channel 4.

[0043] In other embodiments, the first annular body 1 or the second annular body 2 can also be adhesively connected to the membrane body 3 or connected by a snap member with a smaller size, as long as the normal surgical operation is not affected.

[0044] In an alternative embodiment, the support ring body 11 is made of a metal material or a rigid plastic.

[0045] Since both the metal material and the rigid plastic have relatively high hardness, the support ring body 11 made of the metal material or the rigid plastic can provide a better support effect for the first annular body 1.

[0046] When the support ring body 11 is made of a metal material, the metal material includes a stainless steel material or a cemented carbide material; when the support ring body 11 is made of a rigid plastic, the rigid plastic includes polystyrene or polyoxymethylene.

[0047] Exemplarily, when the support ring body 11 is made of a cemented carbide material, since the cemented carbide is an alloy material made by powder metallurgy of hard compounds of refractory metals and binding metals, and has the characteristics of high hardness, wear resistance, good strength and toughness, the support ring body 11 can provide a better support effect for the first annular body 1.

[0048] When the support ring body 11 is made of a rigid plastic such as polystyrene or polyoxymethylene, since polystyrene has relatively high hardness and good electrical insulation properties, and polyoxymethylene has excellent mechanical strength, hardness and wear resistance, the support ring body 11 can provide a better support effect for the first annular body 1.

[0049] It should be noted that after the existing surgery, the doctor needs to remove the incision protection sleeve from the patient. The operation process is that the doctor deforms the inner ring by using the intermediate film and then takes out the inner ring from the patient's wound. However, for a smaller-sized incision protection sleeve, it is difficult for the doctor to operate the action of deforming the inner ring from the outside, so it is not convenient to remove the incision protection sleeve. Herein, the inner ring corresponds to the second annular body 2 in this embodiment.

[0050] To solve the problem of inconvenient removal of the incision protection sleeve, the incision protection sleeve further includes a pulling member 5. One end of the pulling member 5 is connected to the second annular body 2, and the end of the pulling member 5 away from the second annular body 2 is used to be placed outside the patient's body.

[0051] It should be noted that the pulling member 5 has a fixed end 51 and a free end 52. The fixed end 51 of the pulling member 5 is connected to the second ring body 2, and the free end 52 of the pulling member 5 is away from the second ring body 2 and is placed outside the patient's body.

[0052] When it is necessary to take out the incision protection sleeve from the patient's body, pull the free end 52 of the pulling member 5 outwards, so that the second ring body 2 can be taken out of the patient's body. The setting of the pulling member 5 improves the convenience.

[0053] In an alternative embodiment, the pulling member 5 includes a pulling rope 53. One end of the pulling rope 53 is connected to the second ring body 2, and the end of the pulling rope 53 away from the second ring body 2 is for being placed outside the patient's body.

[0054] It should be noted that the pulling rope 53 is a thin rope. The fixed end 51 and the free end 52 are arranged on the pulling rope 53. The fixed end 51 of the pulling rope 53 is connected to the second ring body 2, and the free end 52 of the pulling rope 53 is away from the second ring body 2 and is placed outside the patient's body.

[0055] When it is necessary to take out the incision protection sleeve from the patient's body, pull the free end 52 of the pulling rope 53 outwards, so that the second ring body 2 can be taken out of the patient's body. The setting of the pulling rope 53 improves the convenience.

[0056] In an alternative embodiment, the pulling member 5 further includes a pulling ring 54, and the pulling ring 54 is connected to the end of the pulling rope 53 away from the second ring body 2.

[0057] For the convenience of the doctor's operation, a pulling ring 54 is arranged at the free end 52 of the pulling rope 53. When it is necessary to take out the incision protection sleeve from the patient's body, hook and pull the pulling ring 54 outwards with the hand, and the second ring body 2 can be taken out of the patient's body. The setting of the pulling rope 53 and the pulling ring 54 further improves the convenience.

[0058] In other embodiments, the pulling member 5 includes a hook and a connecting band. The fixed end 51 and the free end 52 are arranged on the connecting band. The fixed end 51 of the connecting band is connected to the second ring body 2, and the free end 52 of the connecting band is away from the second ring body 2 and is placed outside the patient's body. The free end 52 of the connecting band is connected to the hook.

[0059] When it is necessary to take out the incision protection sleeve from the patient's body, hook and pull the hook outwards with the hand, and the second ring body 2 can be taken out of the patient's body. The setting of the hook and the connecting band further improves the convenience.

[0060] In an alternative embodiment, both the first ring body 1 and the second ring body 2 are made of TPU material.

[0061] It should be noted that TPU, or thermoplastic polyurethane elastomer, is a type of elastomer that can be plasticized by heating and dissolved by solvents. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance. It has good processing performance and is widely used in the medical industry.

[0062] In this embodiment, the diameter d2 of the second ring body 2 is greater than the diameter d1 of the first ring body 1. By limiting the diameter d2 of the second ring body 2 to be greater than the diameter d1 of the first ring body 1, a better surgical field of view can be provided during surgery, making it easier to observe the condition inside the patient's body. It is understandable that in other embodiments, according to surgical requirements, the diameter d1 of the first ring body 1 may also be greater than or equal to the diameter d2 of the second ring body 2.

[0063] In an optional embodiment, the diameter d1 of the first ring body 1 is 80-220 mm, and the diameter d2 of the second ring body 2 is 90-230 mm.

[0064] Exemplarily, the diameter d1 of the first ring body 1 is 80 mm, and the diameter d2 of the second ring body 2 is 90 mm; alternatively, the diameter d1 of the first ring body 1 is 120 mm, and the diameter d2 of the second ring body 2 is 130 mm; alternatively, the diameter d1 of the first ring body 1 is 150 mm, and the diameter d2 of the second ring body 2 is 160 mm; alternatively, the diameter d1 of the first ring body 1 is 180 mm, and the diameter d2 of the second ring body 2 is 190 mm; alternatively, the diameter d1 of the first ring body 1 is 220 mm, and the diameter d2 of the second ring body 2 is 230 mm.

[0065] It is understandable that the diameter of the first ring body 1 and the diameter of the second ring body 2 can be determined according to actual surgical needs, as long as the diameter d2 of the second ring body 2 is greater than the diameter d1 of the first ring body 1 .

[0066] The technical effects of the incision protection cover provided by the embodiment of the present application include at least: a supporting ring body 11 for supporting the first ring body 1 is provided inside the first ring body 1, so that the first ring body 1 is not easily deformed, and the first ring body 1 is more easily folded inwardly under the support of the supporting ring body 11, which to a certain extent avoids the deformation of the first ring body 1 and reduces the difficulty of folding the first ring body 1; the supporting ring body 11 is located in the middle position of the first ring body 1, so that it can have a relatively balanced supporting effect on all directions of the first ring body 1; the supporting ring body 11 made of metal material or hard plastic can have a better supporting effect on the first ring body 1; a pulling ring 54 is provided at the free end 52 of the pulling rope 53, and the second ring body 2 can be removed from the patient's body by pulling the pulling ring 54 outward, thereby improving the convenience of operation.

[0067] In summary, the embodiment of the present application provides an incision protection sheath. During the use of the incision protection sheath, the first ring body 1 is placed outside the patient's body, the second ring body 2 is placed inside the patient's body, and the membrane body 3 is connected between the first ring body 1 and the second ring body 2 to form a channel 4 through which the doctor performs the operation. Since a support ring body 11 for supporting the first ring body 1 is provided inside the first ring body 1, and the support ring body 11 is made of a metal material or a rigid plastic, the first ring body 1 is not easily deformed, and the first ring body 1 is more easily turned inward under the support of the support ring body 11, thereby avoiding deformation of the first ring body 1 to a certain extent and reducing the difficulty of turning over the first ring body 1; when it is necessary to remove the incision protection sheath from the patient's body, the second ring body 2 can be pulled out of the patient's body by hooking and pulling the pulling ring 54 with the hand. The arrangement of the pulling rope 53 and the pulling ring 54 improves the convenience of the operation.

[0068] As described above, the above is only the specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
