Description

  The present invention relates to surgical drapes, in particular, various members used during surgery such as a liquid receiving pouch used when operating a joint such as a shoulder, elbow or knee. The present invention relates to a surgical drape that can be easily and reliably attached to an optimal position at an optimal angle without causing damage.

  A surgical drape is a covering used to isolate a clean area or space (space) from a patient or medical device that is defined as dirty in an area defined as a clean field in an operating room. . In particular, it is important to keep the incised part (surgical field) clean during surgery, in order to prevent the patient from being infected from any bacteria during the surgery. In general, it is necessary to isolate the surface of the patient body, which is defined as follows, by a surgical drape provided with a fenestration (a hole provided in advance in the surgical drape). It also isolates the patient's operative field from the rest of the body in order to barrier blood, body fluids, etc. scattered during the operation.

  In the operating room, an operating table on which a patient undergoing surgery is laid is installed, and the area around the operating table in which the patient is covered with a surgical drape is a so-called clean field. This clean field refers to a certain area in the operating room where, for example, the surgeon, instrumentation nurse, and surgical assistant are permitted to perform activities related to the operation. Normally, the clean field is a spatial (three-dimensional) area centered on the operating table (patient surgical field).

  On the other hand, an area other than the clean field in the operation room where a so-called extracurricular nurse who is another nurse related to the surgery is active is called an unclean field. For example, even on the floor below the doctor's waist and near the bottom of the operating table, it becomes an unclean field other than the clean field.

  Here, the unclean field does not mean the “unclean place” in general.

  For example, when a shoulder joint is operated, as shown in FIG. 5, a surgical drape 13 is placed close to a patient 12 who is laid on his / her back (a supine position) on a surgical table 11 that is tilted horizontally or in a beach chair shape. The shoulder 15 of the patient 12 is exposed to the surgical field side (clean side) through the opening 14 formed in the surgical drape 13 by hanging in a curtain shape, and thus the shoulder 15 and the other part are isolated. Hereinafter, the surgical drape suspended in a curtain shape in this way is referred to as a vertical isolation drape.

  In addition, as shown in FIG. 6, a surgical drape 23 is placed on a patient 12 laid sideways (side-down position) on an operating table, and the arm of the patient 12 pulled upward is passed from the shoulder 15 through the fenestration 24 to perform the operation. The field (clean field) is exposed, thus isolating the shoulder 15 from the rest. At this time, a portion other than the shoulder 15 in the arm of the patient 12 who is not a surgical field is also a clean field, so that the clean field is covered with, for example, a clean stockinette 25 or the like. In FIG. 6, numeral 16 is a liquid receiving pouch described later.

  According to the above vertical isolation drape, a wide field of view can be secured due to the space in the joint created by the weight of the patient's own arm, and it is not necessary to perform the operation with forward bending, so the doctor can operate in a posture that does not impose a burden. It is excellent in that it can be done.

  However, according to the vertical isolation drape, since the surgical drape 13 is suspended in a curtain shape, blood and body fluids scattered during the operation may flow down the surgical drape 13 and contaminate the surroundings. is there. In particular, when performing arthroscopic surgery, a large amount of physiological saline is flowed into the joint in order to prevent the viewing field of the endoscope from becoming unclear due to blood, body fluid, or the like flowing out at the time of surgery.

  In order to solve this problem, a liquid receiving pouch for collecting a liquid such as blood, body fluid, or physiological saline is attached to the surgical field side surface of the surgical drape 13.

  An example of a liquid receiving pouch is disclosed in Patent Document 1. As shown in FIG. 7, the liquid receiving pouch 16 is made of resin and formed in a funnel shape, and an opening 17 into which the shoulder 15 of the patient 12 is inserted is formed on the side surface. In addition, a discharge port 19 is formed at the bottom so that a liquid 18 such as blood, body fluid or physiological saline can be drained out of the liquid receiving pouch 16 through a drain pipe 20 connected to the discharge port 19. It has become. An annular shape holding bar 22 is disposed at the edge of the inlet 21 of the liquid receiving pouch 16 in order to keep the inlet 21 open at all times.

JP 2011-255493 A

  Although the liquid receiving pouch 16 can be used to reliably collect the liquid 18 such as blood, body fluid, or physiological saline that flows out during the operation, there are the following problems.

  Conventionally, in order to attach the liquid receiving pouch 16 to the surgical drape 13, the liquid receiving pouch 16 is directly attached to the surgical drape 13 with forceps or the like, or the surgical drape 13 is formed of a tag-like or strip-like piece made of nonwoven fabric (hereinafter referred to as a “strip”). And a tag) are attached in advance, and a part of the liquid receiving pouch 16 is attached with forceps or the like through the tag.

  However, when the liquid receiving pouch 16 is directly attached to the surgical drape 13 with forceps, a hole is opened in the surgical drape 13 due to the force of grasping the forceps or the weight of the liquid receiving pouch, and the barrier property of the surgical drape 13 is impaired. There was a risk of being lost.

  Further, when the liquid receiving pouch 16 is attached to the surgical drape 13 via a tag attached to the surgical drape 13, the attachment position of the liquid receiving pouch 16 is restricted, so that the liquid receiving pouch 16 is attached in accordance with the operation. There was a possibility that it could not be installed at the optimal position at the optimal angle. Since the tag is attached to the surgical drape 13 by adhesion or the like, the tag may be peeled off due to the weight of the liquid receiving pouch 16.

  Furthermore, when a large amount of liquid accumulates in the liquid receiving pouch 16, a tensile force acts locally on the surgical drape 13 at the attachment position of the liquid receiving pouch 16 due to its weight, or a doctor's body (for example, The surgical drape 13 may be broken by the hook of the elbow etc. on the liquid receiving pouch 16 and the barrier property of the surgical drape 13 may be impaired, or the tag may be detached from the surgical drape 13 and the liquid receiving pouch falls. There was a fear.

  Furthermore, a doctor who can only touch clean things in the clean field cannot pick up and lift the liquid receiving pouch 16 that has fallen into the area defined as the unclean field below the operating table, and the operation proceeds. There was a risk of hindrance.

  The above is a case where the liquid receiving pouch 16 is attached to the surgical drape 13, but the same problem occurs when various members such as an electric scalpel cord used in the operation are attached in addition to the liquid receiving pouch 16. there were.

  Therefore, the present invention can damage various kinds of members used during surgery, such as a liquid receiving pouch used when operating a joint such as a shoulder, elbow or knee, in a surgical drape such as opening or tearing. It is an object of the present invention to provide a surgical drape that can be easily and reliably attached to an optimal position at an optimal angle.

  The present invention has been made to achieve the above object, and is characterized by the following.

According to the first aspect of the present invention, in the surgical drape for isolating the patient's operative field from the other parts, two openings used for the operation are provided on the surface of the draped body on the operative field side. Two hooks for attaching the formed liquid receiving pouch so as to be detachable are formed in parallel with a gap, and the hook is formed by folding the drape main body to the surgical field side, An opening window through which the patient's shoulder, elbow or knee is passed is formed between the buttocks of the drape main body, and each of the openings of the liquid receiving pouch is adjacent to the window opening. The patient's arm or leg is passed from one of the openings and the patient's arm or leg is removed from the other opening, and the shoulder, elbow or knee of the patient is placed in the receiving pouch. have a particular feature is intended to expose the Is shall.

The invention described in claim 2 is characterized in that, in the invention described in claim 1, the width of the flange is in the range of 1 cm to 10 cm .

The invention according to claim 3 is characterized in that, in the invention according to claim 1 or 2, the surface on the reaction field side of the drape main body on which the collar portion is formed is reinforced by a reinforcing sheet. It is what you have.

The invention according to claim 4 is characterized in that, in the invention according to claim 3, the reinforcing sheet is welded to the surface on the side of the surgical field of the drape main body by an adhesive or heat sealing. It is.

  According to the present invention, by forming a buttock for attaching various members such as a liquid receiving pouch used at the time of surgery on the surface of the drape body on the surgical field side, various members can be perforated in the surgical drape. It can be easily and reliably attached to the optimum position at the optimum angle without causing damage such as tearing.

  In addition, according to the present invention, the two liquid receiving pouches can be attached to the optimum position at the optimum angle by forming the two collar portions in parallel at intervals.

  Moreover, according to this invention, a liquid receiving pouch can be attached easily and reliably by making the width | variety of a collar part into the range of 1 cm to 10 cm.

  Furthermore, according to the present invention, by reinforcing the surface on the side of the surgical field of the drape main body in which the buttock is formed with the reinforcing sheet, damage such as opening and tearing generated in the surgical drape can be avoided more reliably. be able to.

It is a perspective view which shows the state which suspended the surgical drape of this invention in curtain shape. It is a top view which shows the collar part reinforced with the reinforcement sheet | seat, (a) is a case where a reinforcement sheet is affixed on the surface by the side of the operative field of a drape main body, (b) is a reinforcement sheet in a collar part. (C) is a case where a collar part is formed in two steps. It is a perspective view which shows the state which attaches a liquid receiving pouch to the buttocks of the surgical drape of this invention, and performs an operation. It is the perspective view which looked at the state which attaches a liquid receiving pouch to the buttocks of the surgical drape of this invention, and performs an operation from another direction. It is a perspective view which shows the state which exposed the patient's shoulder to the surgical field side through opening of the vertical isolation drape. It is a perspective view which shows the state which covered the surgical drape on the patient who laid down sideways, and exposed the patient's shoulder to the surgical field side. It is a perspective view which shows the use condition of the liquid receiving pouch disclosed by patent document 1. FIG.

  One embodiment of the surgical drape of the present invention will be described with reference to the drawings, taking as an example the case where a liquid receiving pouch is attached to the surgical drape.

  FIG. 1 is a perspective view showing a state in which the surgical drape of the present invention is suspended in a curtain shape.

  As shown in FIG. 1, the surgical drape of the present invention is for attaching a liquid receiving pouch 2 (see FIGS. 3 and 4) to the surface (A) on the surgical field side of the drape main body 1 in the vertical direction. Two heel parts 3 are formed in parallel with a gap, and a drape body 4 between the heel parts 3 is formed with a fenestration part 4 through which a patient's shoulder, elbow or knee is passed.

  For example, when the shoulder joint is operated, the interval between the buttocks 3 is set so as to sandwich the shoulder. The heel part 3 is formed by folding the drape main body 1 to the operative field side (mountain fold). In addition to forming the collar portion 3 by folding the drape main body 1, the collar portion 3 may be formed separately and attached to the drape main body 1.

  The width of the collar portion 3 is in the range of 1 cm to 10 cm, and more preferably in the range of 3 cm to 7 cm, whereby the liquid receiving pouch 2 can be easily and reliably attached. By sticking the reinforcing sheet 5 to the surface (B) on the side of the surgical field of the drape body 1 in which the collar portion 3 is formed, it is possible to more reliably avoid damages such as perforations and tears that occur in the drape body 1. it can.

  The reinforcing sheet 5 is adhered to the surface (B) on the side of the surgical field of the drape body 1 by welding with an acrylic pressure-sensitive adhesive or heat seal, or bonded with an adhesive tape, or a combination thereof. And good.

  The reinforcing sheet 5 is not particularly limited, but may be a nonwoven fabric, a resin such as polyethylene or polypropylene, or an aluminum. Moreover, you may make an adhesive (adhesive tape) function as a reinforcement sheet.

  Moreover, although the acrylic adhesive was mentioned as an example as an adhesive, another rubber adhesive etc. may be sufficient and it does not specifically limit.

  The affixing position of the reinforcing sheet 5 may be the surface (B) on the side of the surgical field after the heel part 3 is formed, as shown in FIG. As shown, it may be the inner side of the heel part 3 (valley fold part on the reaction field side). As another reinforcing method, as shown in FIG. 2 (c), the heel portions 3 may be formed in duplicate, and the inside of each heel portion 3 (valley fold portion on the reaction field side) may be used. Note that these reinforcing methods may be combined.

In order to attach the liquid receiving pouch 2 to the surgical drape of the present invention, as shown in FIGS. 3 and 4, the edge of the liquid receiving pouch 2 is sandwiched between the two hooks 3 with forceps 6 or the like. Another Attaching or the fold portion 3 pierced sandwich cloth forceps, or strapping, Okuko and the like can be considered to attach a surface fastener or adhesive tape fold portion 3.

  The illustrated liquid receiving pouch 2 has substantially the same configuration as the liquid receiving pouch 16 shown in FIG. 7, but differs only in that two openings 7 and 8 are formed on the side surface. To do. When the shoulder joint is operated, the wrist is passed through the liquid receiving pouch 2 from one opening 7 and is removed from the other opening 8 so that only the shoulder 9 is exposed in the liquid receiving pouch 2. 3 and 4 illustrate the operation on the right shoulder of the patient, but when performing the operation on the left shoulder, the position of the opening 8 is formed at a symmetrical position with the opening 7 as a base point. Use things.

  The same number as the liquid receiving pouch 16 shown in FIG. That is, 19 is a drain outlet for the liquid 18 formed at the bottom of the funnel-shaped liquid receiving pouch 2, 20 is a drain pipe connected to the drain outlet 19, 21 is an inlet of the liquid receiving pouch 2, 22 is , An annular shape retaining bar disposed at the edge of the inlet of the liquid receiving pouch 2.

  Since the collar part 3 is formed over the drape body 1 in the vertical direction, the mounting height position of the liquid receiving pouch 2 can be freely adjusted within the range of the length of the collar part 3. And since the liquid receiving pouch 2 is attached to the two collar parts 3, the attachment angle of the liquid receiving pouch 2 can be freely adjusted by changing the attachment position of right and left.

  In this way, since it can be set to an optimum height according to the height of the doctor and the height of the operating table, the receiving pouch 2 is initially in the unclean field (position lower than the doctor's waist or the operating table Lower position), and the doctor can freely change the position of the liquid receiving pouch during the operation.

  Further, depending on the progress of the operation, the doctor may change the standing position with respect to the operative field, change the angle at which the surgical medical device is directed, or move the patient's arm. The mounting height and angle of the liquid receiving pouch 2 can be freely adjusted so as not to become an obstacle. In particular, an operation using an endoscope is performed while changing the angle and position of the endoscope camera. At this time, the liquid receiving pouch 2 does not interfere with the operation.

  Furthermore, in order to ensure that liquids such as blood, body fluid, and physiological saline are poured into the liquid receiving pouch 2, for example, an operation may be performed in the liquid receiving pouch 2. What must be done is to prevent the liquid receiving pouch 2 from getting in the way when the doctor performs an operation. As described above, it is possible to prevent the liquid-receiving pouch 2 from getting in the way by adjusting the mounting height and angle of the liquid-receiving pouch 2, but it is more difficult to get in the way if the inlet 21 of the liquid-receiving pouch 2 is large. In order to realize this, the interval between the two flange portions 3 formed in parallel may be set wide.

  Specifically, if the interval between the flanges 3 is, for example, 700 mm, the size of the inlet 21 suitable for the liquid receiving pouch 22 can be set. Accordingly, the size of the inlet 21 itself of the liquid receiving pouch 2 needs to be increased. For example, when the length (circumference) of the inlet 21 is 2,100 mm, Since the length is 1,400 mm, a suitable size of the inlet 21 can be secured, and the liquid recovery function of the liquid receiving pouch 2 can be sufficiently exhibited. That is, if the length of the inlet 21 of the liquid receiving pouch 22 and the gap between the flanges 3 are secured in this way, the liquid receiving pouch 2 is attached to the drape main body 1 as shown in FIGS. The front side of the pouch 2 is lowered in a range that does not reach the unclean field, and as a result, the liquid receiving pouch 2 is less likely to get in the way during the operation, so that the liquid recovery function of the liquid receiving pouch 2 can be fully exerted. .

  As described above, the ratio of the interval between the flanges 3 and the length of the inlet 21 on the near side has been described by taking 1: 2 as an example. The lower limit of the length of the side inlet 21 is preferably 1.2 or more and 2.4 or less, more preferably 1.5 or more and 2.1 or less, and more preferably 1.6 or more and 2.0 or less.

  Further, when the weight is increased by attaching a large liquid receiving pouch 2 due to accumulation of physiological saline or the like, the load on the mounting position of the liquid receiving pouch 2 also increases, but the mounting position of the liquid receiving pouch 2 is Since it is the part 3, there is no possibility that it will come off like a conventional tag, and furthermore, the possibility that the drape main body 1 is damaged by applying the reinforcing sheet 5 can be avoided.

  In this manner, the liquid receiving pouch 2 can be attached to the optimum position at the optimum angle in accordance with the operation. That is, as shown in FIG. 3, when the joint of the shoulder 9 is operated, the shoulder 9 inclines to the right in the figure including the arm, so that the liquid receiving pouch 2 is inclined to the right inclining. By adjusting the angle, the liquid recovery effect of the liquid receiving pouch 2 can be sufficiently exhibited.

Fold portion 3 has been described as a portion for mounting the liquid-receiving pouch 2, for example, may be a location to attach the code or drainage tube or the like of the electric knife.

  The above-described example is a case where the surgical drape of the present invention is used while being hung in a curtain shape, but the same effect can be obtained even when the patient is used with the surgical drape.

  Although the example mentioned above is a case of the surgical drape in which the fenestration part is provided in advance, the fenestration part may be made by combining a plurality of drapes in which the fenestration part is not formed. That is, for example, four drapes with no fenestrations are prepared, and two of these are put on the patient in parallel with a gap, and perpendicular to the two drapes already covered with the remaining two. Cover with a gap. In this manner, even when the fenestration is formed at the center of the four drapes, the same effect as in the case of the surgical drape in which the fenestration is provided in advance can be obtained.

  As described above, according to the present invention, a liquid receiving pouch used when operating a joint such as a shoulder, an elbow or a knee over the surface (A) on the operative field side of the drape main body 1 in the vertical direction. Even when the liquid receiving pouch 2 is attached to the surgical drape with forceps or the like by forming the collar portion 3 for attaching 2, the liquid receiving pouch 2 is directly attached to the surgical drape with forceps or the like, The surgical drape can be easily and reliably attached to the optimal position without causing damage such as opening or tearing.

  Moreover, according to this invention, the liquid receiving pouch 2 can be attached at an optimal angle according to the operation by forming two hooks 3 in parallel at intervals.

  Further, according to the present invention, the liquid receiving pouch 2 can be easily and reliably attached by setting the width of the collar portion 3 within a range of 1 cm to 10 cm, preferably 3 cm to 7 cm.

  Furthermore, according to the present invention, when a large amount of liquid accumulates in the surgical drape by reinforcing the collar 3 by attaching the reinforcing sheet 5 to the surface of the drape body 1 on the side opposite to the surgical field. Even so, it is possible to reliably avoid the possibility of damage such as piercing or tearing in the surgical drape due to its weight.
