Specific implementation mode

For the ease of the understanding of those skilled in the art, the utility model is made with reference to embodiment and attached drawing further Explanation, the content that embodiment refers to not is restriction to the utility model.

In the description of the present invention, it should be understood that term "upper", "lower", "front", "rear", "left", "right", The orientation or positional relationship of the instructions such as "vertical", "horizontal", "top", "bottom", "inner", "outside" be orientation based on ... shown in the drawings or Position relationship is merely for convenience of describing the present invention and simplifying the description, and does not indicate or imply the indicated device or member Part must have a particular orientation, with specific azimuth configuration and operation, therefore should not be understood as limiting the present invention.

In the description of the present invention, it should be noted that unless otherwise specified and limited, term " installation ", " phase Even ", " connection " shall be understood in a broad sense, for example, it may be mechanical connection or electrical connection, can also be the company inside two elements It is logical, it can be directly connected, can also indirectly connected through an intermediary, for the ordinary skill in the art, it can To understand the concrete meaning of the term as the case may be.

As shown in Fig. 1 or Fig. 3, a kind of Wound protector includes that operation path is used to form made of elastic material Incision protection film 1, the upper end of incision protection film 1 is connected with snap ring 2, lower end is connected with lower snap ring 3, under incision protection film 1 End or lower snap ring 3 are equipped with several first smoke intaking holes 4,2 inner hollow of upper snap ring, and upper snap ring 2 is connected to it equipped with several Second smoke intaking hole 8 of inner cavity, the outside of incision protection film 1 are equipped with lower end or the lower snap ring of connection upper snap ring 2 and incision protection film 1 3 and the connection structure of smoke path 5 is formed, upper snap ring 2 is equipped with the connecting tube 6 for connecting vacuum extractor, and connecting tube 6 connects The inner cavity of logical upper snap ring 2.

When operation starts, Wound protector is supported in operative incision, the inside of incision protection film 1 forms operation and leads to Vacuum extractor in operating room is connected by pipeline with connecting tube 6, under the swabbing action of vacuum extractor, was performed the operation by road The operation smoke generated using the equipment such as laser knife or electric knife in journey can be by underbalance effect from the first of Wound protector Smoke intaking hole 4 enters in smoke path 5, then rises and is entered in the inner cavity of upper snap ring 2 by the second smoke intaking hole 8, finally It is discharged from the port of connecting tube, is inhaled into vacuum extractor, thus can dramatically avoid operation smoke pair The obstruction of doctor's sight reduces harm of the operation smoke to medical worker.

As a preferred solution, as shown in Figure 3-4, aforementioned coupling structure includes being circumferentially positioned at incision protection film 1 The tube chamber of several gas-guide tube 5a in outside, gas-guide tube 5a are smoke path 5, and the upper and lower ends of gas-guide tube 5a are separately connected Two smoke intaking holes 8 and the first smoke intaking hole 4.The smog that surgical procedure generates through in the first smoke intaking hole 4 to gas-guide tube 5a, then through second into Cigarette hole 8 enters the inner cavity of upper snap ring 2, is finally discharged from the port of connecting tube 6.

As another preferred scheme, as shown in Figs. 1-2, aforementioned coupling structure is setting in 1 outside of incision protection film Cylindrical outer wall 7, the upper end of cylindrical outer wall 7 is connect with upper snap ring 2, lower end is connect with lower snap ring 3, and cylindrical outer wall 7 and notch are protected There are gaps between cuticula 1, to form smoke path 5.In the present embodiment, smoke path 5 has larger space, energy More operation smokes are accommodated to pass through.

It should be noted that two kinds of above-mentioned connection structures are intended only as what more preferably mode was proposed, this field skill Art personnel should be understood that the structure that can be connected to the first smoke intaking hole 4 and the second smoke intaking hole 8 can be realized what the utility model was reached Technique effect, therefore other than the mode of smoke path 5 provided in this embodiment, also various ways can be in the prior art Realize goal of the invention, details are not described herein.

In embodiments above, the quantity of the first smoke intaking hole 4 is three or three or more, and makes the first smoke intaking hole 4 On the even lower end for being arranged at intervals on incision protection film 1 or lower snap ring 3, the quantity of the second smoke intaking hole 8 is three or three or more, and So that the second smoke intaking hole 8 is disposed in an evenly spaced relation on snap ring 2 so that operation smoke can more fully enter smoke path 5 into And it is rapidly detached.

Further, in the above-described embodiment, the outer diameter of upper snap ring 2 and lower snap ring 3 is all higher than 1 shape of incision protection film At operation path outer diameter, when being supported in operative incision due to Wound protector, lower snap ring 3 is located at the bottom of operative incision Portion, upper snap ring 2 then against and hang on human body surface, can make in this way Wound protector it is more stable be supported on operative incision, It prevents from being slipped in human intracavity.

In addition, upper snap ring 2, lower snap ring 3 and cylindrical outer wall 7 are all made of elastic material and are made, in the present embodiment, Elastic material selects polyurethane, and polyurethane has preferable toughness, and it is wear-resisting, ageing-resistant, processing performance is good, and polyurethane Kink resistance it is good, be often used on medical instrument.

Above-described embodiment is the preferable implementation of the utility model, and in addition to this, the utility model can be with other sides Formula realizes that any obvious replacement is in the protection model of the utility model under the premise of not departing from the technical program design Within enclosing.

In order to allow those of ordinary skill in the art more easily understand the improvement of the utility model compared with the existing technology it Place, some attached drawings of the utility model and description have been simplified, and for the sake of clarity, present specification is omitted one A little other elements, those of ordinary skill in the art should be aware that the element that these are omitted also may make up the interior of the utility model Hold.
