[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] See also Figures 1 to 3 The incision protector 100 of a preferred embodiment of the present invention is used to be installed in an incision for surgical instruments to pass through. The incision protector 100 includes a protective sleeve 20 and an end cap 40. The protective sleeve 20 is used to be partially inserted into the incision. The end cap 40 is covered at one end of the protective sleeve 20 located outside the incision.

[0029] The end cover 40 includes a top wall 41 and a peripheral wall 43. The protective cover 20 is sleeved on the peripheral wall 43 for fixing. The top wall 41 is provided with a through hole 410 for the instrument to enter and exit.

[0030] The end cover 40 further includes a closing plate 45 and a flap valve 412 for closing the through hole 410. In the illustrated embodiment, the closing plate 45 covers an end of the through hole 410 away from the protective sleeve 20. The flap valve 412 is located at an end of the through hole 410 close to the protective sleeve.

[0031] The closing plate 45 is provided with a connecting hole 450 connected to the through hole 410. The aperture of the connecting hole 450 is smaller than the aperture of the through hole 410. Preferably, the aperture of the through hole 410 is larger than the preset diameter of the largest instrument passing through; the aperture of the connecting hole 450 is smaller than the preset diameter of the smallest instrument passing through.

[0032] The closing plate 45 is made of a flexible material so that the hole wall of the connecting hole 450 can be stretched open by the instrument passing through. After the hole wall of the connecting hole 450 is stretched open by the instrument, the hole wall of the connecting hole 450 covers the passing instrument, thereby closing the through hole 410 together with the instrument. The material of the closing plate 45 is a deformable material such as silicone, rubber, etc.

[0033] The flap valve 412 closes the through hole 410. When an instrument passes through, the instrument hits the flap valve 412, causing the flap valve 412 to move outward and perforate the through hole 410 to allow the instrument to pass through.

[0034] Preferably, the flap valve 412 is a double flap structure, which is substantially V-shaped. Along the direction close to the center of the through hole 410, the flap valve 412 gradually moves away from the top wall 41. The structure of the flap valve 412 can facilitate the passage of instruments.

[0035] In the illustrated embodiment, the closing plate 45 is substantially circular and is detachably mounted on the top wall 41. In the illustrated embodiment, the top wall 41 is provided with a slot (not shown) at one end away from the flap valve 412. The slot is coaxial with the through hole 410 and its diameter is slightly larger than that of the through hole. The closing plate 45 is clamped in the slot. It is understood that in other embodiments, the closing plate 45 can be fixed to the top wall 41.

[0036] The protective sleeve 20 includes a sleeve 21, a first elastic ring 23 and a second elastic ring 25. The first elastic ring 23 and the second elastic ring 25 are respectively disposed at two ends of the sleeve 21.

[0037] The sleeve 21 is roughly cylindrical. The material of the sleeve 21 includes but is not limited to soft materials such as rubber, silicone, thermoplastic polyurethanes (TPU), etc. The sleeve 21 can be turned over and deformed. Preferably, the sleeve 21 is made of a transparent material.

[0038] The first elastic ring 23 and the second elastic ring 25 are respectively arranged at opposite ends of the sleeve 21. The first elastic ring 23 and the second elastic ring 25 can deform when subjected to force and elastically recover after the external force is removed. The first elastic ring 23 clamps the peripheral wall 43 by elastic retraction to fix the end cover 40.

[0039] In the illustrated embodiment, the end cap 40 further includes an outer wall 47 and a support ring 49. The outer wall 47 is formed on the top wall 41 and surrounds the outer side of the peripheral wall 43. The support ring 49 is used to be installed between the outer wall 47 and the first elastic ring 23. Preferably, the outer wall 47 can be bent to partially cover the support ring 49 for fixing. The hardness of the support ring 49 is greater than that of the first elastic ring 23, so as to fix and support the cutout.

[0040] When the incision protector 100 is in use: the second elastic ring 25 is deformed into a flat shape and the second elastic ring 25 and the sleeve 21 are installed in the incision. The first elastic ring 23 is turned over to the position where the incision needs protection and support. The outer wall 47 of the end cover 40 is turned over to the side away from the flap valve 412, and then the end cover 40 is installed in the first elastic ring 23, so that the first elastic ring 23 can fix the end cover 40 by elastically retracting and clamping the peripheral wall 43. After that, the support ring 49 is installed outside the first elastic ring 23, and the outer wall 47 is turned over to cover the support ring 49. The instrument enters the incision by opening the flap valve 412. When the instrument is installed, the hole wall of the connecting hole 450 can be opened by the instrument to allow the instrument to pass through, and the hole wall of the connecting hole 450 is covered on the instrument to close the through hole 410. The flap valve 412 and the closing plate 45 respectively close the through hole 410 to ensure the stability of the air pressure in the incision.

[0041] When removing the incision protector 100, the outer wall 47 is turned over and the support ring 49 is peeled off. Since the end cap 40 is fixed by the elastic retraction force of the first elastic ring 23, the end cap 40 can be easily and directly removed. The first elastic ring 23 and the second elastic ring 25 can be removed from the incision by elastic deformation.

[0042] The incision protector 100 isolates the contact between the instrument and the incision through the protective cover 20 to reduce infection. The incision protector 100 simultaneously closes the through hole 410 through the closing plate 45 and the flap valve 412 to maintain the pressure balance in the incision. The closing plate 45 can remain sealed when the instrument passes through repeatedly. The flap valve 412 closes the through hole 410 when no instrument passes through, and can stop the impact of gas when the instrument passes through.

[0043] Furthermore, the first elastic ring 23 and the second elastic ring 25 can circumferentially support the incision 360 degrees, thereby maximizing the surgical working area.

[0044] Furthermore, the first elastic ring 23 can be turned inside or outside the sleeve 21 to facilitate adjusting the length of the sleeve 21. Since the first elastic ring 23 fixes the end cap 40 by elastic retraction, the end cap 40 will not be affected by turning inside or outside.

[0045] Further, the incision can be selectively supported flexibly through the first elastic ring 23 or rigidly through the support ring 49. The support ring 49 is installed separately from the protective sleeve 20, and the incision is first supported flexibly through the first elastic ring 23, and then the support ring 49 is installed, so as to facilitate installation and avoid damaging the incision. When removing, the outer wall 47 can be turned over at any time, and the support ring 49 can be easily peeled off and the first elastic ring 23 and the second elastic ring 25 can be deformed and taken out. Especially in an emergency, the incision protector 100 can be quickly removed without destructive removal such as shearing.

[0046] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the technical solution of the present invention.
