Description

  The present invention relates to a surgical aid used at the time of a surgical operation performed in a medical field, and in particular, by covering a surgical site, blood, bone fragments, and the like are prevented from being scattered from the surgical site to the surroundings and contaminating the surroundings. The present invention relates to a surgical cover.

  In surgical fields such as orthopedic surgery, brain surgery, and cerebral chest surgery, surgical techniques such as cutting and excision of bones and tissues are performed using electric or pneumatic tools such as saws and drills. In that case, by covering the periphery of the surgical site with a sterile cloth (drape) as described in Patent Document 1 and Patent Document 2, by exposing the surgical site from the opening formed in the sterile cloth, The sterility and cleanliness of the surgical site are ensured.

  In addition, in the surgical operation as described above, it is inevitable that tissue pieces such as blood and bone fragments are scattered from the surgical site to the surroundings, but from the viewpoint of hygiene and prevention of nosocomial infection, blood and the like It is desirable to prevent adhesion to an operator or operating room. In particular, since adhesion of blood may cause secondary infection from a patient to an operator or the like, it is important to protect the operator or the like from blood or a piece of tissue. However, the sterile cloth is used to perform an operation by exposing the surgical part while covering the periphery of the surgical part, and cannot prevent blood or the like from being scattered around. Therefore, conventionally, in addition to surgical wear, goggles and masks are used to prevent blood and the like from directly attaching to the operator's face, or a face guard as described in Patent Document 3 is worn. I was doing.

  Goggles and masks are effective in protecting the mucous membrane of the face that is likely to cause infection, but there is a problem that it is not possible to prevent scattered matter from adhering to the face not covered with them. In addition, the face guard can protect the entire face, but there is a problem that it is unsuitable for a long-time operation because it causes poor ventilation and causes a temperature rise and may cause discomfort such as obstructing the motor function. there were.

  In addition, goggles, masks, face guards, etc. are used to prevent scattered objects from the surgical site from adhering to the surgeon, as with surgical clothes. There was a problem that it could not be protected from contamination.

  Therefore, the object of the present invention is to solve the above-mentioned problems in the prior art, protect the surgeon and nurses from the scattered material from the surgical site, prevent contamination of the operating room and the like by the scattered material, To reduce the risk of secondary infection during surgery.

In view of the above-described object, the present invention is a surgical cover for covering a surgical site and preventing surrounding contamination by scattered matter from the surgical site, and is a cylindrical body formed of a transparent sheet and extending in the vertical direction. The upper end is squeezed to form a small-diameter upper opening, and the lower end of the cylindrical body is attached with an annular frame along the entire circumference to form a lower opening having a larger diameter than the upper opening, Furthermore, the cylindrical shape is formed in a three-dimensional shape that widens from the upper opening toward the lower opening by a plurality of support members extending along the cylindrical body from the annular frame toward the upper opening. The body is supported and the inside of the cylindrical body can be accessed through the upper opening , and the annular frame and the support member can be deformed by applying an external force and maintain the deformed shape. Shape from possible material Is is to provide a surgical cover.

  The cylindrical body is formed by an annular frame attached along the entire circumference of the lower opening of the cylindrical body and a plurality of, preferably 3 to 5, support members extending from the annular frame toward the upper opening. It is held in a divergent three-dimensional shape, forming a space inside it. In the surgical cover of the present invention, the surgical site is confined in the internal space of the cylindrical body by placing the cylindrical body in contact with the lower opening of the cylindrical body around the surgical site. The interior space is used as a space for surgery. And by restricting the scattering of blood or the like to the internal space of the cylindrical body in this way, the blood or the like is prevented from scattering from the surgical site to the surgeon or operating room. Moreover, since the cylindrical body is formed of a transparent sheet, the surgeon can perform an operation while looking at the surgical site, and does not disturb the visual field of the surgeon. Further, the upper opening of the cylindrical body is a portion that allows the operator to access the internal space of the cylindrical body, while allowing blood or the like to scatter from the inside of the cylindrical body to the outside. However, the upper opening of the cylindrical body is narrowed to a smaller diameter than the lower opening, thereby reducing the possibility that blood or the like scatters from the internal space of the cylindrical body to the outside. .

  Moreover, it is preferable that the said upper side opening part is restrict | squeezed by the elastic annular member so that the opening area can be expanded / contracted.

Said annular frame and said support member is made of a material capable of holding the deformable and and shape after deformation by applying an external force, for example, Ru is formed from fiber reinforced resin or resin coated steel. As a result , the shape of the lower opening can be made to follow the surface of the surgical site, and the shape of the cylindrical body can be changed to a desired shape according to the application.

  As described above, according to the surgical cover of the present invention, it is possible to cover the surgical site with the transparent cylindrical body held in a three-dimensional shape and perform the surgery in the internal space of the cylindrical body. Thereby, the scattering of blood etc. from the surgical site is limited in the internal space of the cylindrical body, while protecting the surgeon etc. from the scattered material from the surgical site, and also prevents contamination of the operating room etc. by the scattered material, It has the effect of reducing the risk of secondary infection during surgery.

  Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, for the sake of simplicity, the annular frame 19, the elastic annular member 21, and the support member 23 are shown in a simplified manner.

  Referring to FIG. 1, a surgical cover 11 of the present invention includes a cylindrical body 13 that extends in the vertical direction. A large-diameter lower opening 15 is formed at the lower end of the cylindrical body 13, and an upper opening 17 having a smaller diameter than the lower opening 15 is formed at the upper end. The cylindrical body 13 is formed of a flexible thin transparent sheet so that the inside can be seen. The transparent sheet may be any sheet having flexibility such as olefin resin and soft polyvinyl chloride, but in consideration of incineration after use, non-chlorine system such as ethylene resin or ethylene vinyl acetate copolymer A sheet made of resin is preferred.

  An annular frame 19 is attached to the lower opening 15 of the cylindrical body 13 along the entire circumference of the periphery, so that the opened shape can be maintained. The annular frame 19 is formed of a flexible material that can be deformed by applying an external force and can retain the deformed shape so that the user can use the annular frame 19 in a state of being deformed into a desired shape. Preferably it is. For example, as the material of the annular frame 19, a metal wire such as a metal wire, a resin-coated metal wire such as a resin-coated steel material, a fiber reinforced resin, or the like can be used. In addition, it is preferable to form a cyclic | annular frame from the fiber reinforced resin which does not use a metal from a viewpoint of making the process after disposal easy.

  For example, as shown in FIG. 3, the annular frame 19 is attached around the lower opening 15 of the cylindrical body 13 along the entire circumference thereof. This is done by accommodating the annular frame 19 in a pocket formed in this manner. For example, as shown in FIG. 3, the pocket folds the opening edge at the lower end of the cylindrical body 13 over the entire circumference in the axial direction of the cylindrical body 13, and the opening edge is the inner periphery of the cylindrical body 13. It can form by joining to a surface or an outer peripheral surface. You may form a pocket by sticking a strip | belt-shaped member on the cylindrical body 13 in the circumferential direction. Further, as shown in FIG. 4, an annular frame 19 in which a belt-like body coated with a wire material such as a wire with resin is formed as an annular frame 19, and this is used as an opening edge at the lower end of the cylindrical body 13. You may attach the annular frame 19 to the lower end part of the cylindrical body 13 by adhere | attaching along a perimeter.

  On the other hand, the upper opening 17 is formed by constricting the upper end of the cylindrical body 13 into a gather shape by the elastic annular member 21 attached along the entire circumference around the upper end opening of the cylindrical body 13. . Accordingly, the opening area of the upper opening 17 can be expanded as necessary. As a material of the elastic annular member 21, for example, rubber can be used. The elastic annular member 21 is attached to the upper end portion of the cylindrical body 13, for example, elastically in a pocket formed along the entire circumference around the upper end opening of the cylindrical body 13 as shown in FIG. 5. This is done by accommodating the annular member 21. For example, the pocket is formed by folding the opening edge of the upper end of the cylindrical body 13 over the entire circumference in the axial direction of the cylindrical body 13 and joining the opening edge to the inner peripheral surface or the outer peripheral surface of the cylindrical body 13. Can be formed.

  The cylindrical body 13 is supported by a plurality of, preferably 3 to 5 linear support members 23 extending along the side surface of the cylindrical body 13 from the annular frame 19 toward the upper opening 17 in order to maintain a three-dimensional shape. Has been. The support member 23 is formed of a flexible material that can be deformed by applying an external force and can retain the deformed shape so that the user can use the support member 23 in a state of being deformed into a desired shape. Preferably it is. The support member 23 is preferably formed from the same material as the annular frame 19. For example, as the material of the support member 23, a metal wire such as a metal wire, a resin-coated metal wire such as a resin-coated steel material, a fiber reinforced resin, or the like can be used.

  In order to keep the cylindrical body 13 in a three-dimensional shape, the lower end portion of the support member 23 is fixedly joined to the annular frame 19 by welding, adhesion, or pressure bonding. Of course, other joining methods can be used as long as the support member 23 and the annular frame 19 can be fixedly joined. On the other hand, as shown in FIG. 2, a loop portion is formed at the upper end portion of the support member 23. By passing the elastic annular member 21 inside the loop portion, the upper end portion of the support member 23 and Connection with the elastic annular member 21 is made. Of course, other connection methods can be adopted as long as the expansion and contraction of the elastic annular member 21 is not hindered. Further, the support member 23 and the elastic annular member 21 do not necessarily have to be connected, and the support member 23 may terminate in front of the elastic annular member 21 in the vicinity of the upper end portion of the cylindrical body 13.

  Further, for example, as shown in FIG. 6, the support member 23 is attached to the cylindrical body 13 in a pocket formed by joining the circumferentially separated parts of the cylindrical body 13 to each other. 23 can be accommodated. In addition, as shown in FIG. 7, when a belt-like body coated with a wire or the like with a resin is used as the support member 23, the side surface of the tubular body 13 is directed from the annular frame 19 toward the upper opening 17. The support member 23 can be attached to the side surface of the cylindrical body 13 by adhering the belt-shaped body along the side. Although not shown, the support member 23 may be attached to the tubular body 13 by other methods such as accommodating the support body in a pocket formed by sticking the belt-like member to the tubular body in the axial direction. Of course.

  In this manner, the cylindrical body 13 having the small-diameter upper opening 17 and the large-diameter lower opening 15 is moved downward from the upper opening 17 by the annular frame 19 and the plurality of support members 23. A space is provided inside the cylindrical body 13 so as to be supported in a three-dimensional shape that expands toward the opening 15 so that an operation can be performed.

Next, a method of using the surgical cover shown in FIG. 1 will be described with reference to FIG.
First, the surgeon 25 places the lower opening 15 of the surgical cover 11 around the surgical site of the patient 27, and the annular frame 19 of the lower opening 15 of the surgical cover 11 is shaped around the surgical site. Combine and transform. In addition, if necessary, a force is applied to the plurality of support members 23 so as to obtain a desired three-dimensional shape.

  Thus, after transforming the cylindrical body 13 into a desired three-dimensional shape, the surgeon 25 keeps his hand out of the cylindrical body as shown in FIG. The surgical instrument is inserted into the internal space of the tubular body 13 through the through hole. In addition, since the opening area of the upper side opening part 17 can be expanded / contracted and the opening area of the upper side opening part 17 can be enlarged as needed, it is easy to insert a big instrument or both hands. Thus, the workability of the surgeon 25 is not impaired.

  Next, the operator 25 performs an operation in the internal space of the cylindrical body 13. At this time, since the cylindrical body 13 is transparent, the surgeon 25 can perform an operation while visually recognizing the surgical site through the cylindrical body 13.

  Thus, since the surgical site is covered with the cylindrical body 13 and is confined in the internal space of the cylindrical body 13, the scattering of blood and the like from the surgical site is limited to the internal space of the cylindrical body 13. In addition, the surgeon 25 and the operating room are protected from scattered matter such as blood. In addition, the cylindrical body 13 basically has a divergent shape from the upper opening 17 toward the lower opening 15, so that a large area of the surface of the patient 27 can be covered with the cylindrical body 13. On the other hand, since the upper opening 17 that can scatter blood from the inside of the cylindrical body 13 to the outside is small, the possibility that blood or the like scatters from the inside of the cylindrical body 13 to the outside is reduced. Yes. Furthermore, since the opening area of the upper opening 17 can be expanded and contracted, the edge of the upper opening 17 contracts around the hand of the operator 25 during the operation, and the opening of the upper opening 17 Area is minimized. Thereby, the possibility that blood or the like scatters from the surgical site to the outside of the cylindrical body 13 through the upper opening 17 is further reduced.

  The embodiment of the present invention has been described above with reference to the drawings. However, the illustrated embodiment is only one of the embodiments of the present invention, and the present invention is limited to the illustrated embodiment. It is not a thing. For example, in the illustrated embodiment, the cylindrical body 13 has been described as being formed from a transparent sheet. However, the cylindrical body 13 is at least partially formed from a transparent sheet, and the inside of the cylindrical body is formed. It is only necessary to be able to operate while visually recognizing.
