Description

Endo Bag {ENDO BAG}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endo bag, and more particularly, to an endo bag used for carrying a part of body tissue or a tumor during endoscopic surgery.

Unlike conventional laparotomy, laparoscopic surgery is being performed to minimize the incision of the skin and to restore the patient 's speed.

Such a laparoscopic operation is a surgical procedure performed by observing the operation site of the abdominal cavity by making a tube to the abdomen of the patient using a surgical apparatus called Trocar and introducing a surgical instrument such as an endoscope into a surgical site in the abdominal cavity, Resection, biliary stones removal, head dendriticectomy, general surgery and so on.

Here, the trocar refers to a medical instrument used for approaching the abdominal cavity, and the trocar is inserted and fixed into the body through a navel or a skin incision (incision) of a patient, and a structure in which a laparoscopic surgical instrument is inserted To be exposed to the outside.

Through the incision of the abdomen, the surgical instruments for surgery can be inserted, as well as the exudates (organs, lumps, cancer tissues, etc.) generated during surgery can be taken out.

In order to remove the tumor or internal sculpture removed during the surgical procedure, a transparent vinyl bag called an endo-bag is used which is inserted into the abdominal cavity together with an endoscope and a surgical instrument Next, the removed tumor or internal organs are put into an endo bag and taken out of the abdominal cavity.

Korean Patent No. 10-0729444 discloses an endo bag for endoscopic surgery. Specifically, a vinyl bag is formed by using a transparent vinyl material harmless to the human body, and the end of the vinyl bag is easily identified By forming an identification band so that the plastic bag can be directly inserted into the abdominal cavity through the trocar, the convenience of the practitioner due to the operation of the abdominal cavity can be improved and the insertion of a solid body such as a metallic spring or other plastic rod It is disclosed that the abdominal cavity injury of a patient to be caused is prevented, and the amount of the medical instrument and the waste thereof used in the abdominal surgery is minimized, thereby reducing the operation cost and preventing environmental pollution.

On the other hand, a large volume of the extraction material may be generated during the extraction of the endo bag with the extract. For example, in the case of a gallbladderectomy (a procedure in which gallstones are resected together with a part of the gallbladder) When it is desired to withdraw, it becomes difficult to withdraw through the trocar port because of its size. At this time, a method of grinding and withdrawing gallstones implanted in endo bags through surgical scissors is mainly used.

However, in some cases, it is difficult to insert and grind a surgical instrument into the endo bag for crushing the extract, and in order to solve such a problem, Korean Patent No. 10-1202489 discloses a method for grinding an extract An endo bag for accommodating an exudate, which is injected into the abdominal cavity and removed during an endoscopic surgery procedure, in an inner space part, is connected to an inner space part of the endo bag, At least two fingers extending a predetermined length from one side of the endo bag are formed so as to be exposed to the outside of the abdominal cavity.

Korean Patent No. 10-1202489 discloses an endo bag which can easily grind the extract while receiving the extract in the inner space of the endo bag. Therefore, bulky extracts, even tumor lumps, It can safely be crushed in the abdominal cavity without any side effects such as damage to other organs in the abdominal cavity.

As described above, in Korean Patent No. 10-1202489, the end portion of the finger portion is drawn out to the outside of the abdominal cavity in a state where the endo bag is inserted into the abdominal cavity, and then the forceps, an endoscope, or the like is inserted into the inside of the abdominal cavity, have.

However, in order to insert the surgical instrument into the inside of the finger while the end of the finger is drawn out of the abdominal cavity, stable support of the finger must be accompanied. In Korean Patent No. 10-1202489, however, , And needs to be improved.

The finger portion disclosed in Korean Patent No. 10-1202489 should be bundled with a separate thread when the endo bag is taken out of the abdominal cavity. This process is not only troublesome but also a part of the exudate through the hole of the finger portion There is a risk of leakage.

On the other hand, endo bags may be damaged in the process of pulverizing the exudates (gallstones, etc.) contained in the endo bag through surgical scissors, etc., and when the endo bags are broken, gallstones and bile enter the abdominal cavity and contaminate the surgical site.

Conventional endobags, including the above-mentioned prior art, suffer from these problems, and accordingly, the development of endowed bags in a reinforced form is required.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, the well-known functions or constructions are not described in order to simplify the gist of the present invention.

FIG. 1 is a perspective view showing an endo bag guiding apparatus 1 according to an embodiment of the present invention, FIG. 2 is a perspective view showing the endo bag 100 shown in FIG. 1, FIG. 4 is a cross-sectional view showing a state in which the elastically deformed portion 160 is drawn out of the abdominal cavity in the endo bag 100 shown in FIG. 3, and FIG. 5 is a cross- Sectional view showing a state in which the elastic deformation portion 160 is deformed by the elastic member 190.

The endo bag 100 according to the present invention is used to hold a part of a body tissue or a tumor during endoscopic surgery and is folded or dried like a plastic bag. For this purpose, the endo bag 100 is made of latex or Polyethylene resin or the like.

The endo bag guiding device 1 which is a device used for introducing and withdrawing the endo bag 100 into the inside of the body has an insert rod 10, a guide tube 20, a pulling wire 30 And an insert tube (40).

The insert rod 10 is formed in the shape of a long rod and is coupled with two springs 11 at its front end. The spring 11 is coupled to the endo bag 100 to support the endo bag 100. The spring 11 is formed in the form of a thin thin plate spring and is curved in a state in which no external force is applied, thereby supporting the endo bag 100 so as to be opened in the form of a bag.

The guide tube 20 has an elongated tube shape. The insert rod 10 is inserted into the guide tube 20, and a spring 11 coupled with the endo bag 100 protrudes in front of the insert tube.

The pulling wire 30 is coupled onto the endo bag 100 and penetrates the inside of the guide pipe 20 and extends toward the back of the guide pipe 20 so that the handle 31 is coupled to the rear end. The endo bag 100 can be pulled backward with respect to the guide tube 20 by pulling the handle 31 backward.

The insert tube 40 has an elongated tube shape and is sized to allow the guide tube 20 to be inserted therein so that the guide tube 20 inserted in the insert tube 40 can be moved back and forth.

The endo bag 100 coupled on the spring 11 when the endo bag 100 is not used is stored in the insert tube 40 in a folded or rolled state where the spring 11 is in a long extended state, The end rod 100 and the spring 11 protrude toward the front side of the insert tube 40 while the insert rod 10 and the guide tube 20 move forward with respect to the insert tube 40 when the end bag 100 is used. .

The endo bag 100 according to the present invention may include the base bag 110, the protrusion 150, and the elastic deformation portion 160.

The endo bag 100 may further include a support ring 170, a guide tube 180, and a recovery wire 190.

In the drawings according to the present invention, only one protrusion 150 and the elastic deforming part 160 are shown, but it is also possible to provide two or more protrusions 150 and resiliently deformable parts 160, As shown in FIG. Also, it is needless to say that the support ring 170, the guide tube 180, and the recovery wire 190 are provided in two or more.

The base bag 110 is in the form of a bag and has an opening at the upper side thereof. The base bag 110 may be a single ply or may be composed of two ply 110a and 110b. When the base bag 110 is composed of the two ply 110a and 110b, it is possible to effectively prevent the effluent from flowing out even when a part of the base bag 110 is broken.

A binding flap 140 may be formed on the upper edge of the base bag 110.

The coupling flap 140 is coupled with the upper end of the base bag (the first base surface 111 and the second base surface 112) folded downward to form a passage 141 therein, And the pulling wire 30 is inserted into the passageway 141 in the coupling flap 140 to be coupled thereto.

The protrusion 150 is formed in the shape of a tube, and has a passage through which a surgical instrument such as a forceps or an endoscope is inserted. In the present invention, such a passage is referred to as a 'channel'. That is, the channel 151 is provided when the protrusion 150 is pulled and inserted into the surgical instrument. (However, due to the characteristic of the protrusion 150 made of a flexible material such as vinyl, the channel 151 The protrusion 150 may be fixed to the wall surface of the base bag 110 at one side and may be joined by heat fusion at this time.

The protrusion 150 is preferably made of a material having elasticity so as to be stretched or deformed.

The protrusion 150 may be made of the same material as the base bag 110, and may be made of latex or polyethylene resin.

Alternatively, the protrusion 150 may be made of a material different from the base bag 110, and may be formed of a material having a higher elongation than the base bag 110.

The protrusion 150 may have a constant diameter along its longitudinal direction, or may have a reduced diameter as it moves away from the base pouch.

The wall surface portion of the base bag 110 to which the protrusion 150 is coupled may have a clogged shape (the accommodating space 113 of the base bag 110 does not communicate with the channel 151 of the protrusion 150) Or alternatively may be an open form (the receiving space 113 of the base bag 110 is communicated with the channel 151 of the protrusion 150).

When one end of the protrusion 150 is coupled to the wall surface of the base bag 110 and the other end of the protrusion 150 is pulled away from the protrusion 150, the protrusion 150 may be extended to form the channel 151, It is possible to insert the surgical instrument into the channel 151 of the protrusion 150.

When the inner end of the channel 151 of the protrusion 150 is blocked by the wall surface of the base bag 110, the base wall 110 is pierced by the end of the surgical instrument, So that the surgical instrument can be inserted into the base bag 110 through the channel 151 of the protrusion 150. That is, the receiving space 113 inside the base bag 110 and the inside of the channel 151 can communicate with each other.

As described above, the protrusion 150 of the endo bag 100 according to the present invention is a means for forming a passage for inserting the surgical instrument into the base bag 110. When the protrusion 150 is stretched or deformed, And this channel 151 forms a passage through which the surgical instrument is inserted (see FIG. 4)

The support ring 170 is in the form of a ring and is coupled to the end of the protrusion 150. The support ring 170 forms the boundary between the protrusion 150 and the elastically deformable portion 160.

The support ring 170 is made of a material capable of being elastically deformed and may have a greater rigidity or a greater thickness than the protrusions 150 or may be harder than the protrusions 150.

The support ring 170 is formed in such a manner that the protrusion 150 protrudes from the channel 151 when the resiliently deformed portion 160 penetrates the abdominal wall 3 and the skin 2 and is drawn out of the abdominal cavity and supported on the skin 2. [ So that the resiliently deformable portion 160 can be easily opened.

When the channel 151 is to be formed in the protrusion 150, the support ring 170 is preferably drawn out of the abdominal cavity. The support ring 170 forms a substantial inlet when a surgical instrument or the like is inserted into the channel 151.

The support ring 170 may be configured to have a different color from the protrusion 150. For example, when the protrusion 150 is a transparent material or achromatic color, the support ring 170 may be chromatic.

When the channel 151 is provided in the protrusion 150, the support ring 170 can be gripped and pulled using a surgical forceps such as a forceps. At this time, the support ring 170 is relatively rigid The support ring 170 can be easily grasped by making it larger or thicker and easy identification can be achieved through the separated colors of the support ring 170. [

The elastic deforming portion 160 is extended at the end portion of the protruding portion 150. That is, on the opposite side of the base bag 110 to the protrusion 150. The diameter of the opposite end of the elastic deforming portion 160 which is engaged with the protrusion 150 varies according to the deformation of the elastic deforming portion 160.

The resiliently deformable portion 160 is a portion extended to the outside of the abdominal cavity and the resilient deformable portion 160 is a portion of the abdominal cavity outside the abdominal cavity (the abdominal wall 3 and the skin 2) The skin 2 can be brought into close contact with the skin 2 while being widened in a state of being drawn out in a state of being drawn out by the surface of the skin 2, This ensures that the formation of the channel 151 of the protrusion 150 is stably maintained and that the protrusion 150 and the resilient deforming portion 160 are prevented from being inadvertently pushed into the abdominal cavity.

The resiliently deformable portion 160 may be formed in a cylindrical shape or may be divided into a plurality of portions such that the resiliently deformable portion 160 is separated from the outer edge of the protruded portion 150, Lt; / RTI >

The elastic deformable portion 160 is engaged with the protruding portion 150 so that the elastic deformable portion 160 spreads in a manner that the diameter is expanded as described above. That is, the outer end of the elastically deformable portion 160 is opened so that its diameter becomes larger than the diameter at the point where it is connected to the protrusion 150.

In order to facilitate such an action, the elastic deforming portion 160 may include the soft portion 161 and the hard portion 162. [

The soft portion 161 is in the form of a tube and extends from the protrusion 150. At this time, the soft portion 161 may be integrated with the protrusion 150.

The rigid portion 162 is formed in an elastically deformable plate shape and is joined to the outer circumferential surface or the inner circumferential surface of the soft portion 161. The hard portion 162 may be divided into a plurality of portions and may be coupled along the circumferential direction of the soft portion 161. When the soft portion 161 is not provided, 150). &Lt; RTI ID = 0.0 >

The hard portion 162 is made of a material harder than the soft portion 161. For example, the hard portion 162 may be made of urethane.

The resiliently deformable portion 160 may be fixed to the skin by holding the portion of the hard portion 162 and fixing the resiliently deformable portion 160 to the skin in a state in which the diameter of the resiliently deformable portion 160 is enlarged.

In the process of fixing the resiliently deformable portion 160 to the skin, the supporting ring 170 can easily maintain the shape of the inlet of the channel 151, and the resiliently deformable portion 160 is relatively harder than the protruding portion 150 So that it can be easily fixed to the skin.

The resilient deformations 160 may also be configured to have a different color than the protrusions 150, such as the support ring 170. When the channel 151 is to be formed on the protrusion 150, the resiliently deformable portion 160 may be gripped and pulled by using a surgical forceps such as a forceps, It is possible to easily grasp the elastic deformable part 160 by using a relatively large or thicker stiffness than that of the elastic deformable part 160,

In the endo bag according to the present invention, the resiliently deformable portion 160 may be in a state in which the soft portion 161 is excluded, wherein the rigid portion 162 of the resiliently deformable portion 160 is positioned at the end of the protruded portion 150 May be directly coupled or may be coupled to support ring 170.

The guide tube 180 is in the form of a tube and is located within the protrusion 150. The guide tube 180 may be formed in the form of a rectangular tube, a circular tube, or the like.

One end of the guide tube 180 is coupled to a point where the protrusion 150 and the elastic deforming portion 160 are connected and the remaining portion is positioned inside the protrusion 150 without being engaged with the protrusion 150.

The guide pipe 180 is made of a material harder than the protrusion 150. For example, the guide pipe 180 may be made of urethane.

The guide tube 180 helps the protrusion 150 to easily form the channel 151 and also prevents the sharpened portion of the trocar or surgical instrument or the like when the trocar, Thereby preventing the protrusion 150 from being torn or damaged.

The recovery wire 190 is in the form of a lasso and is joined along the edge of the elastic deformation portion 160. To this end, a flexible portion 163 is provided at the end of the elastic deformation portion 160 to receive the recovering wire. The recovery wire 190 is for separating the elastically deformed portion 160 expanded in the end portion diameter and is divided into a circular seal portion 191 and a pulling chamber portion 192. When the pulling chamber 192 is pulled, the diameter of the circular chamber 191 decreases and the diameter of the elastic deforming portion 160 (in particular, the diameter of the variable portion 163) decreases.

The pulling yarn 192 of the recovering wire 190 is exposed to the outside through the protrusion 150 and the inside of the base pouch 110 through the inside of the base pouch 110. By pulling the pulling chamber 192, It is possible to seal the portion 160 and prevent the exudate from flowing out through the elastic deforming portion 160. [

The protruding portion 150 and the resilient deforming portion 160 may be brought into close contact with the base bag 110 to reduce the overall volume of the end bag 100, (100) itself to the outside of the abdominal cavity.

The endo bag 100 according to the present invention may include a first reinforcement surface 120 and a second reinforcement surface 130. The base bag 110 (the first base surface 111 and the second base surface 112), the first reinforcing surface 120 and the second reinforcing surface 130 are coupled to each other, (The first bonding lines 121 and 122, the second bonding lines 131 and 132, the first boundary line 124 and the second boundary line 134 may be formed by thermal fusion). has exist)

The base bag 110 may include a first base surface 111 and a second base surface 112 and the first base surface 111 and the second base surface 112 may have the same shape. The base bag 110 has a bag shape in which the first base surface 111 and the second base surface 112 are overlapped with each other and the upper side is opened. In other words, except for the upper edge, the first and second base surfaces 111 and 112 are connected or joined with each other, except for the upper portion, and the accommodation space 113 is formed therein Respectively.

The first base 111 has a first lower region 111a and the first lower region 111a is an area overlapping the first reinforcing face 120 on the first base 111. [ The first lower region 111a may be formed to occupy the entire area of the first base surface 111 or occupy a certain area of the first base surface 111. In the latter case, The region 111a occupies the lower side of the first base surface 111. [

The second lower surface 112a is provided on the second base surface 112 and the second lower surface 112a is an area overlapping the second reinforcing surface 130 on the second base surface 112. [ This second lower region 112a can also be made to occupy the entire area of the second base surface 112 or occupy a certain area of the second base surface 112, The region 112a occupies the lower side of the second base surface 112. [

The first reinforcing face 120 is a portion coupled to the first basic face 111 and may have the same size and shape as the first basic face 111 or may be formed as shown in Figures 6 and 7, And the first base surface 111, as shown in FIG.

Even if the first reinforcing surface 120 is smaller than the first basic surface 111, the first basic surface 111 and the first basic surface 111 are matched with the first basic surface 111 in size and shape . That is, the first reinforcing face 120 has the same size and shape as the first lower region 111a.

It goes without saying that the first reinforcing face 120 may be made larger than the first lower region 111a.

The first reinforcing surface 120 may be coupled to the inside of the first base surface 111 (inside the base bag 110), but is preferably coupled to the outside of the first base surface 111, Accordingly, it is possible to prevent the exudate from flowing between the first base surface 111 and the first reinforcing surface 120.

The first reinforcing face 120 may be face-engaged in the first lower region 111a of the first basic face 111 but the first reinforcing face 120 may be joined to the first basic face 111 along the rim thereof. And is preferably coupled to the first lower region 111a. That is, the first base 111 is formed with a space between the first lower region 111a and the rim of the first base 111,

The lines connecting the first reinforcing face 120 and the first lower region 111a are first coupling lines 121 and 122, respectively.

The second reinforcing surface 130 is a portion coupled to the second base surface 112 and may have the same size and shape as the second base surface 112 or may be formed as shown in Figures 6 and 7 And the second base surface 112, as shown in FIG.

However, even when the second reinforcing face 130 is smaller than the second basic face 112, the second base face 112 has a size and shape corresponding to the second basic face 112 . That is, the second reinforcing face 130 has the same size and shape as the second lower region 112a.

The second reinforcing face 130 may be larger than the second lower region 112a.

The second reinforcing surface 130 may be coupled to the inside of the second base surface 112 (inside the base bag 110) but is preferably coupled to the outside of the second base surface 112, Accordingly, it is possible to prevent the exudate from flowing between the second base surface 112 and the second reinforcing surface 130. The second reinforcing face 130 is combined with the first reinforcing face 120 to form a bag shape, and a bag other than the basic bag can be formed.

The second reinforcing surface 130 may be surface bonded to the second lower surface 112a of the second base surface 112 while the second reinforcing surface 130 is bonded to the second base surface 112 along the rim thereof. And is preferably coupled to the second lower region 112a.
