Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a skin surface covering device. Background Art

[0002] OSE technology can be understood as a coaxial endoscope technology in which the working channel is separated from the endoscope body. Its working and observation channels are both located in the same soft tissue channel. Its outstanding feature is that there is no fixed channel restriction. It has both the convenience of free operation of coaxial endoscope and the wide field of view of unilateral dual-channel endoscope, and has higher mutual coordination and flexibility.

[0003] However, in actual intraoperative operation, due to the large size of the surgical hole and the lack of protection and restriction, there is a risk of excessive loss of water medium during the operation, resulting in insufficient water pressure during the operation and a blurred surgical field.

[0004] Secondly, because the surgical incision is too large, the operating channel and observation mirror on the incision surface lack a certain degree of auxiliary stability.

[0005] Therefore, a skin surface covering device is proposed to solve the current deficiencies. Utility Model Content

[0008] The covering pad is provided with at least one through hole in the middle portion along its length direction. The covering pad comprises an application patch and a support layer. The support layer is provided in the middle portion of the upper side of the application patch. An adhesive layer is provided around the bottom side of the application patch to adhere to the skin surface around the surgical hole.

[0009] Slots communicating with the through holes are symmetrically provided at both ends of the support layer, and a drawer sealing plate cooperating with the through holes is movably provided in the slots.

[0032] Combined with attachment Figure 1-6 As shown, a skin surface covering device includes a covering pad 1 and a drawer sealing plate 2;

[0033] The covering pad 1 is provided with at least one through hole 3 along its length in the middle. Specifically, the number of the through holes 3 can be set according to the actual needs of the instruments used during the operation. In this embodiment, the number of the through holes 3 is two, and the through holes 3 are symmetrically arranged at both ends of the supporting layer 5.

[0034] The covering pad 1 includes a patch 4 and a support layer 5. Specifically, the structural form of the patch 4 can be set according to actual conditions, including but not limited to circular, rectangular, and irregular shapes. In this embodiment, the patch 4 is rectangular. By fitting the patch 4 with the skin around the surgical hole, the surgical hole can be covered, the outflow of aqueous medium during the operation can be avoided, the water pressure during the operation can be ensured, and the clarity of the surgical field during the operation can be improved.

[0035] The support layer 5 is provided in the middle of the upper side of the patch 4. Similarly, the structure of the support layer 5 can be set according to actual conditions. In this embodiment, the support layer 5 is a rectangular parallelepiped structure with a certain thickness. In a specific implementation, the support layer 5 is fixedly connected to the patch 4.

[0036] During implementation, the support layer 5 is used to place the pull-out sealing plate 2. Specifically, the support layer 5 is made of an elastomer, which can ensure that the patch 4 fits the skin while also allowing the pull-out sealing plate 2 to move within the support layer 5.

[0037] Moreover, the support layer 5 made of elastomer can avoid being affected by the operation of the instrument in the hand when the intraoperative instrument is extended into the surgical operation area through the through hole 3 due to the elasticity of the support layer 5. At the same time, the support layer 5 provided with the through hole 3 for the intraoperative instrument to pass through can provide certain support assistance for the operation of the instrument during the operation, thereby ensuring its stability during use.

[0038] As another embodiment, in a specific implementation, a groove 9 is provided in the middle of the patch 4 to cooperate with the support layer 5. The patch 4 is located in the groove 9 and is connected to the support layer 5 by bonding. Through the detachable connection between the support layer 5 and the patch 4, the patch 4 can be placed separately from the fixed part formed between the support layer 5 and the pull-out sealing plate 2. At the same time, during use, the patch 4 can be easily replaced, or the support layer 5 and the pull-out sealing plate 2 can be recycled.

[0039] The bottom side of the patch 4 is provided with an adhesive layer 6 that is adhered to the skin surface around the surgical incision. Specifically, the patch 4 is made of medical flexible material and can be adhered to the skin around the surgical incision. By setting the adhesive layer 6 at the edge of the patch 4, a fixed connection between the patch 4 and the skin around the surgical incision can be achieved.

[0040] Slots 7 communicating with the through hole 3 are symmetrically provided at both ends of the support layer 5 , and a drawer sealing plate 2 cooperating with the through hole 3 is movably provided in the slots 7 .

[0041] During implementation, the slots 7 located on both sides of the support layer 5 are in an unconnected structure, one end of the pull-out sealing plate 2 is located in the slot 7 and is slidably connected to the support layer 5, and the corresponding through hole 3 can be closed and opened by moving the pull-out sealing plate 2 in the slot 7. Specifically, the through hole 3 can be opened by pulling out the pull-out sealing plate 2, which can facilitate the insertion of intraoperative instruments through the through hole 3 into the surgical operation area. At the same time, at the unused through hole 3, the pull-out sealing plate 2 can be pushed into the slot 7 to block the through hole 3, thereby ensuring that a certain pressure is maintained in the surgical operation area and improving the clarity of the surgical field during surgery. Moreover, by blocking the unused through hole 3, blood can be prevented from flowing to the skin surface during surgery.

[0042] Furthermore, a limit block 8 cooperating with the through hole 3 is provided on the bottom side of the pull-out sealing plate 2 . Specifically, when the limit block 8 cooperates with the through hole 3 , the end of the pull-out sealing plate 2 abuts against the slot 7 .

[0043] During the implementation process, the cooperation between the limit block 8 and the through hole 3 can ensure the stability of the relative position of the pull-out sealing plate 2 when blocking the through hole 3, and avoid the separation between the pull-out sealing plate 2 and the through hole 3 caused by the shaking of the patient or the pushing of the pull-out sealing plate 2 during the operation of the surgical instrument.

[0044] At the same time, the connection between the upper end of the through hole 3 in the slot 7 and the limit block 8 and the pull-out sealing plate 2 is an arc structure that cooperates with each other. During implementation, the coordinated setting of the arc structure can facilitate the pulling out of the pull-out sealing plate 2 from the support layer 5.

[0045] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
