Description

Hemostatic pad insertion device for laparoscopic surgery, and circularly wound hemostatic pad used therefor}

The present invention relates to an instrument for inserting a hemostatic sponge pad into the abdomen through a trocar (trocar) during laparoscopic surgery, and more specifically, a hemostatic pad and a pusher inserted into a tube installed in a trocar during laparoscopic surgery It relates to a device for inserting a hemostatic agent pad capable of preventing the internal high-pressure gas (carbon dioxide) from being arbitrarily discharged to the outside.

In addition, the present invention also includes a sponge pad for hemostasis wound in a circular shape so that it can be used in the above instrument.

Conventionally, laparoscopic surgery is performed by making one or several small holes (incisions) of 0.5 to 1.5 cm in size in the abdomen, and inserting a camera and various instruments into them, unlike open surgery, which is performed by opening a large incision in the abdomen. As a surgical method, it is also called 'minimally invasive surgery'.

To outline laparoscopic surgery, after the patient is anesthetized, a needle is inserted into the patient's navel to create a state of relief (inflating the abdominal cavity by injecting carbon dioxide into the abdominal cavity), and a trocar (trocar) as many as required for the appropriate position K. A thin tube that allows the instrument to go in and out of the stomach) is pierced. When a camera is inserted through the trocar, intra-abdominal images are projected on a monitor in front of the operator, and the operator performs the desired operation using an appropriate laparoscopic instrument while watching the monitor.

On the other hand, in order to assist surgical hemostasis during a surgical operation, biologically absorbable hemostatic sponges made of a block, plate or film of an appropriate size may be applied to the bleeding site.

These hemostatic sponges can be used for surgery of large abdominal organs (liver, spleen or small intestines), lung surgery, neurosurgery to prevent pressure damage to the brain or nervous tissue, and frequent and difficult to contain by other means. It is useful for promoting control of bleeding in some cases of surgical operations or other injuries, such as orthopedic surgery with extensive bleeding, vascular surgery to stop bleeding from seeping at suture sites, oral or dental surgery such as tooth extraction.

However, since the pad-shaped hemostatic sponge has a large area, it is difficult to insert it into the human body during laparoscopic surgery. In addition, even if the hemostatic sponge is inserted into the human body, there is a problem that it does not come into close contact with the bleeding part and floats up due to body fluids.

In order to solve the above-mentioned problems, the present applicant developed a device capable of inserting a hemostatic pad into the human body (inside the abdomen) through a trocar (trocar) during laparoscopic surgery, and filed a Korean Patent Application No. 10-2022-0003039 have done

However, in laparoscopic surgery, high-pressure gas (carbon dioxide) is injected into the abdomen to inflate the abdomen. Due to this high-pressure carbon dioxide, the hemostatic pad and rod (push rod) inserted into the tube inserted into the trocar are expelled to the outside. There may be problems with random discharge.

The present invention has been proposed to solve the above problems, and prevents the hemostatic pad and push rod inserted into the tube installed in the trocar (trocar) during laparoscopic surgery from being arbitrarily discharged to the outside by the high-pressure carbon dioxide inside the abdomen. Its purpose is to provide a device for inserting a hemostatic agent pad.

Another object of the present invention is to provide a hemostatic sponge pad that is used in this device and does not float on top because it adheres to the bleeding area when applied to the bleeding area.

During laparoscopic surgery, since the position of the pusher 30 is fixed to the tube 11 by the fixing means, it is possible to prevent the hemostatic pad and/or the pusher 30 from being arbitrarily discharged to the outside by the high-pressure gas inside the abdomen. Tongs, adhesive tape, etc. may be used as these fixing means, but preferably, the first and second fastening holes 14 and 31 and the safety pin 50 may be used.

The tube 11 penetrates the first handle 15 vertically but may include an extension 13 that extends upward more than the first handle 15 . Also, the first fastening hole 14 is formed to pass through the extension part 13 in the lateral direction, and the second fastening hole 31 is formed to pass through the push rod 30 in the lateral direction. The safety pin 50 is formed by inserting the push rod 30 into the pipe 11 so that the first and second fastening holes 14 and 31 are positioned so as to correspond to each other, and then the first and second fastening holes 14 and 31 are It is installed so as to penetrate and fix the position of the push rod 30 to the pipe 11.

A second handle 32 may be installed at the upper end of the push bar 30 . When the second handle 32 is caught on the upper end of the tube 11, it is possible to prevent the push rod 30 from completely falling into the tube 11.

When the safety pin 50 is installed in the first and second fastening holes 14 and 31, the position of the first and second fastening holes 14 and 31 so that the lower end of the hemostatic pad is located inside the tube 11 It is preferable that the lengths of the push rod 30 and the tube 11 are determined.

It should be interpreted as a meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined. Therefore, since the embodiments described in this specification and the configurations shown in the drawings are merely embodiments of the present invention and do not represent all of the technical spirit of the present invention, various equivalents that can replace them at the time of the present application It should be understood that there may be variations and examples.

[Apparatus for inserting hemostatic pad for laparoscopic surgery]

1 is an exploded perspective view showing an insertion mechanism and a hemostatic pad according to a preferred embodiment of the present invention, and FIG. 2 is a combined perspective view of FIG. 1 showing a state in which the hemostatic pad is inserted into the tubular member. In the drawing, the dotted line indicates the inside visible through the transparent or translucent part.

As shown in the figure, the insertion mechanism 100 includes a tube member 10, a pusher 30 inserted into the tube member 10 and pushing the hemostat pad 200 down to discharge it, and a pusher 30 It includes a fixing means for fixing the position of the pipe member 10.

The tube 11 is formed elongate along its longitudinal direction. The upper and lower ends of the pipe 11 are open. The hemostatic pad 200 may be inserted into the tube 11 through the bottom or top of the tube 11 .

The upper end of the tube 11 passes through the first handle 15 and extends further upward than the first handle 15. In this specification and claims, this extended portion will be referred to as the extension portion 13. . Therefore, the extension part 13 is a part of the pipe 11, and is a name for distinguishing it from other parts of the pipe 11. A first fastening hole 14 is formed in the extension part 13 . The first fastening hole 14 is formed to pass through the extension part 13 in the lateral direction, which will be described in detail below.

And, although it is shown that one first fastening hole 14 is formed in the drawings, the number of first fastening holes 14 may be increased as needed. That is, when the safety pin 50 is installed to pass through the first and second fastening holes 14 and 31, it is preferable that the lower end of the hemostatic pad 200 is inside the tube 11. For this purpose, the hemostatic pad ( 200), the safety pin 50 may be installed in an appropriate first fastening hole 14 among several first fastening holes 14 in consideration of the length of the first fastening hole 14.

The tube 11 may be made of a metal such as stainless steel or a synthetic resin such as PC, PVC, PP, PET, or PE. Preferably, tube 11 is transparent or translucent to allow viewing of the interior.

The tube 11 may be inserted into a trocar (instrument used during laparoscopic surgery, not shown in the drawing) and inserted into the human body. Thus, the tube 11 has an outer diameter capable of being inserted into a trocar (more precisely, a cannula of the trocar). And, the pipe 11 has an inner diameter equal to or larger than the outer diameter of the push rod 31 so that the push rod 31 can be inserted therein.

Holes 12 may be formed in the tube 11 at predetermined intervals along its length. When the hemostatic pad 200 is inserted into or discharged from the tube 11, air is discharged or introduced through the hole 12, so that the hemostatic pad 200 can be smoothly inserted and discharged. Also, graduations (not shown in the drawing) may be formed along the longitudinal direction of the pipe 11 . The scale indicates the depth into which the tube 11 is inserted.

The first handle 15 is a part that the user holds, and may be provided on the top of the pipe 11. Through-holes are formed in the first handle 15 so as to penetrate the first handle 15 vertically. The tube 11 is installed on the first handle 15 so as to pass through the through hole. The first handle 15 may be made of metal or synthetic resin.

The push rod 30 has a rod shape elongated in the longitudinal direction of the pipe 11, and has a diameter (outer diameter) inserted into the pipe 11. A second handle 32 may be provided at an upper end of the push rod 30 . The second handle 32 prevents the push rod 30 from completely falling into the tube 11 by being caught on the upper end of the tube 11 .

The lower end of the push rod 30 is preferably formed round in a hemispherical shape.

The push rod 30 can move up and down while being inserted into the tube 11. The push rod 30 may be made of a metal such as stainless steel or a synthetic resin such as PC, PVC, PP, PET, or PE.

Graduations (not shown in the drawing) may be formed on the push bar 30 in its longitudinal direction. The scale indicates the depth into which the push rod 30 is inserted. When the second handle 32 is caught on the upper end of the tube 11 (ie, the upper end of the extension), the lower end of the pusher 30 is preferably located below the lower end of the tube 11, which is the hemostatic pad ( 200) is to ensure that it is completely discharged from the pipe (11).

The second handle 32 is a part held by the user and may be provided at the upper end of the push bar 30 . The second handle 32 may be made of metal or synthetic resin. The second handle 32 can prevent the push rod 30 from completely falling into the tube 11 by being caught on the upper end of the tube 11 (the upper end of the extension part).

The fixing means fixes the position of the push bar 30 to the pipe member 10. In laparoscopic surgery, a gas (eg, carbon dioxide) is injected into the abdomen at high pressure to inflate the abdomen, and the inside of the abdomen is in a high-pressure state due to this gas. However, during laparoscopic surgery, when the tube 11 is left inserted into the cannula of a trocar (not shown), the hemostatic pad 200 and/or the push rod 30 are randomly discharged to the outside due to the high pressure inside the abdomen problems may arise. The fixing means is a configuration proposed to solve this problem, and fixes the position of the push rod 30 to the pipe member 10. If the position of the push rod 30 can be fixed to the pipe member 10, tongs (tweezers that simultaneously pick up and fix the push rod and the tube), tape (adhesive tape attached to connect the push rod and the tube), etc. can be used, An insertion mechanism having such a fixing means is also included in the scope of the present invention.

Preferably, the fixing means may include a first fastening hole 14, a second fastening hole 31, and a safety pin 50. The first and second fastening holes 14 and 31 have a diameter through which the safety pin 50 can pass. As shown in FIG. 2, after the push rod 30 is inserted into the extension part 13 and the first and second fastening holes 14 and 31 are positioned to correspond to each other, the safety pin 50 first and second fastening It is installed to pass through the balls 14 and 31 so that the position of the pusher 30 can be fixed to the pipe 11.

When the position of the push rod 30 is fixed to the tube 11 by the fixing means, it is preferable that the lower end of the hemostatic pad 200 is located inside the tube 11, which means that the hemostatic pad 200 is the tube ( 11) This is because the hemostatic pad 200 may be gelated by surrounding body fluids when exposed to the outside. That is, the length and , the positions of the first and second fastening holes 14 and 31 may be determined.

As shown in FIGS. 4A to 4B, the safety pin 50 includes a handle 51, a pin part 52 extending long from the handle 51, and wings 53 protruding laterally from the end of the pin part 52. And, it may include an elastic spring that provides elastic restoring force to the wings 53.

The handle 51 is a part that the user holds. And, the pin part 52 is a rod having a diameter (outer diameter) capable of penetrating the first and second fastening holes 14 and 31 .

The wings 53 are installed to be rotatable around the pivot shaft 54 at the end of the fin unit 52 . And, the elastic spring provides elastic restoring force to the wings 53. An elastic spring is inserted inside the pin part 52.

As shown in FIG. 4A, when the wing 53 is unfolded, it has a larger width w than the diameter of the first and second fastening holes 14 and 31, and as shown in FIG. 4B, the first and second fastening holes ( 14) When the wing 53 is rotated to be folded while passing through (31), the elastic spring provides an elastic restoring force to the wing 53 so that it returns to its original state (the wing is unfolded). Therefore, after the pin part 52 passes through the first and second fastening holes 14 and 31 and is fastened, the pin part 52 cannot arbitrarily separate from the first and second fastening holes 14 and 31, and the user The pin part 52 is separated from the first and second fastening holes 14 and 31 only when the handle 51 is pulled with force.

[Hemostat pad wound in a circle]

5 is a flow chart showing a process for manufacturing a hemostatic pad (sponge pad for hemostasis). Below, the process will be sequentially described.

First, collagen, preferably a collagen sponge, is mixed with water to make a collagen 0.5-2wt% mixed solution, preferably a 1wt% mixed solution, and a carboxymethyl cellulose-based compound (eg, Sodium CMC) is mixed with water to make a carboxymethyl A 0.5 to 2wt% mixed solution of a cellulose-based compound, preferably a 1wt% mixed solution is prepared.

Subsequently, the collagen mixture and the carboxymethyl cellulose-based compound mixture are mixed at a volume ratio of 1:1, and thrombin is added to the mixture and stirred (S310). The input amount of thrombin can be mixed so that the thrombin per 1 mg of the lyophilized sponge pad is 10 to 1000 IU. In addition, thrombin per 1 mg of the freeze-dried sponge pad may be 10 to 1000 IU, and the weight ratio of the collagen to the carboxymethyl cellulose-based compound may be 1:9 to 9:1.

As an alternative to this ratio, the hemostatic sponge may be composed of 20 to 40 wt% of thrombin, 20 to 40 wt% of collagen, and 20 to 40 wt% of a carboxymethyl cellulose compound. If the amount of thrombin is less than 10 IU or less than 20wt%, the hemostatic effect is poor, and if the amount of thrombin is more than 1000 IU or more than 40wt%, the amount of collagen and carboxymethyl cellulose compound is relatively small, so collagen Functions such as regeneration and recovery of damaged tissue and suppression of scar formation, which are the effects of the drug, cannot be performed properly, and the excellent liquid absorption and liquid retention properties of carboxymethyl cellulose compounds cannot be obtained, so a large amount of blood or exudate from the bleeding area is absorbed. This can make it difficult to retain.

As an alternative to this, thrombin may be added to the mixture so that it is 2 to 50% by weight of the sponge pad for hemostasis. At this time, if thrombin is included in less than 2% by weight, the hemostatic effect may be very low, and if it is included in more than 50% by weight, the chemical stability of the entire hemostatic sponge is lowered because collagen and carboxymethyl cellulose-based compounds are relatively small. However, it is not preferable because the hemostatic effect may be lowered or the liquid absorption and liquid retention performance are deteriorated.

As the collagen, type 1 collagen made using porcine dermis can be used. For this purpose, commercially available collagen may be used. This collagen is obtained by treating the dermis with pepsin to remove telopeptides, and is suitable for medical use. In addition, the collagen may be freeze-dried to have a sponge form. The collagen sponge has a structure in which many pores are included and at least some of the pores are connected to each other.

The carboxymethyl cellulose-based compound refers to carboxymethyl cellulose or a salt thereof, and the salt may include sodium carboxymethyl cellulose (CMC), carboxymethyl cellulose potassium, or a mixture thereof, but is not necessarily limited thereto. it is not going to be Preferably, the carboxymethyl cellulose-based compound is carboxymethyl cellulose sodium (Sodium CMC).

The carboxymethyl cellulose-based compound has excellent liquid absorption and liquid retention properties at the same time. Therefore, when used as a component of a hemostasis sponge, a large amount of blood or exudate from a bleeding site can be absorbed and retained. Therefore, a hemostatic pad made of this sponge can be closely adhered to the bleeding site.

For reference, the degree of liquid absorption was calculated by the following equation by measuring the weight (weight before liquid absorption) of the hemostasis sponge, immersed in 0.9% physiological saline at 25 ° C. for 10 minutes, and measuring the weight after liquid absorption.

The degree of liquid retention was measured by measuring the weight (weight before liquid absorption) of the hemostatic sponge, immersed in 0.9% physiological saline at 25 ° C for 10 minutes, and then applying a pressure of 40 mmHg to the porous structure (sponge) absorbed liquid for 1 minute. Then, the weight of the porous structure (weight after pressing) was measured and calculated by the following formula.

For example, if the hemostatic pad (sponge) is 'a sponge made by freeze-drying a mixture of collagen, thrombin, and sodium CMC', the absorbency is 18 and the retention is 12, which means 'a mixture of collagen and thrombin is freeze-dried. It is much better than the case of 'sponge' (liquid absorption and liquid retention cannot be measured). Therefore, if the hemostatic agent (hemostatic sponge) contains a carboxymethyl cellulose-based compound such as Sodium CMC, it has excellent liquid absorption and excellent shape stability, maintaining a high level of liquid absorption even after pressurization, thereby exhibiting excellent liquid retention. This indicates that when the hemostatic pad according to the present invention is applied to a bleeding site, it can adhere to the bleeding site and can be prevented from being floated up by blood or the like at the bleeding site.

Next, the mixed solution after stirring is poured into a tray and lyophilized to prepare a sponge pad (S320). The sponge pad has a structure in which a plurality of pores are connected to each other (i.e., a sponge structure).

After lyophilization is completed, the sponge pad is cut into a rectangle having a predetermined width (S330). The area may be determined in consideration of the thickness of the sponge pad and the inner diameter of the pipe 11. That is, after the rolled sponge pad is inserted into the tube 11 in a slightly compressed state, the sponge pad returns to its original state and generates frictional force with the inner surface of the tube, so that it can be fixed inside the tube 11. Such frictional force The sponge pad may be cut to have a diameter sufficient for this to occur.

Next, the cut sponge pad is wound in a circular shape to manufacture the hemostatic agent pad 200 . 6 shows a hemostatic pad 200 that has been manufactured. When the hemostatic pad 200 is inserted into the tube 11 in a slightly compressed state, the hemostatic pad 200 returns to its original state and generates frictional force with the inner surface of the tube, whereby the hemostatic pad 200 is fixed inside the tube. can On the other hand, when the hemostatic pad 200 is pushed down using the rolling pin 30, the hemostatic pad 200 overcomes the frictional force and is discharged downward, and the hemostatic pad 200 discharged downward can be spread flat by restoring force. there is. And, this unfolding is helpful when attaching the hemostatic pad 200 to the surgical site using an endoscope.

On the other hand, the above has been described for the case where the hemostatic pad is made by freeze-drying a mixture of thrombin, collagen, and a carboxymethyl cellulose-based compound, but it is not necessarily limited thereto, and the hemostatic pad is a mixture containing hemostatic components, for example, collagen and A mixture of thrombin may also be prepared by lyophilization.

In addition, although the present invention has been described above by taking laparoscopic surgery for a human body as an example, the technical idea according to the present invention can also be applied to laparoscopic surgery on animals other than humans, which will be apparent to those skilled in the art after reading this specification. will be.
