Description

[Technical field]

[0001] The present disclosure relates to a liquid suction device and a liquid suction system for use in endoscopic surgery. [Background technology]

[0002] In surgical procedures, endoscopic surgery is known to be less stressful for patients than open surgery. In endoscopic surgery, a surgical sponge such as SECREA (registered trademark) is known as an instrument that can push or absorb liquid without damaging organs (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2012-135542 A Summary of the Invention [Problem to be solved by the invention]

[0004] Such sponge bodies are inserted into the body through a trocar during surgery. However, although the sponge body has a liquid absorbing function, it does not have a function to drain the absorbed liquid. Therefore, it is difficult for the sponge body to continuously maintain its liquid absorbing function.

[0005] In order to address the above-mentioned issues, it is conceivable to reduce the amount of liquid in the sponge body by sucking the absorbed liquid from the sponge body through a tube that is not connected to the sponge body using an aspirator. In this case, the surgeon must operate the sponge body and the tube separately. Since the operations of endoscopic surgery are basically performed outside the body, each operation is difficult, and it is not desirable to increase the number of operations required.

[0006] The present disclosure provides a liquid suction device and a liquid suction system that reduce the complexity of operations performed by a surgeon in endoscopic surgery and can continuously suck up liquid within the body. [Means for solving the problem]

[0007] One aspect of the present disclosure is a liquid suction device used in endoscopic surgery to absorb liquids from within a patient's body, the liquid suction device comprising: a tube that is inserted into the body via a trocar placed on the surface of the patient's body, has a hole on one end and is capable of suctioning from the other end; and a sponge body that is connected to and surrounds the one end of the tube, and has absorbent properties and elasticity.

[0008] One aspect of the present disclosure is a liquid suction system including the above-mentioned liquid suction device and an aspirator that performs suction from the other end of the tube of the liquid suction device. Effect of the Invention

[0009] According to the present disclosure, it is possible to reduce the complexity of operations performed by a surgeon in endoscopic surgery and to continuously absorb liquids within the body. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, the embodiments will be described in detail with reference to the drawings as appropriate. However, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or duplicate explanation of substantially the same configuration may be omitted. This is to avoid the following explanation becoming unnecessarily redundant and to facilitate understanding by those skilled in the art. Note that the attached drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] FIG. 1 is a diagram showing an example of the overall configuration of a liquid suction system according to an embodiment of the present disclosure. The liquid suction system 100 is a system used in endoscopic surgery to absorb liquid generated in the patient's body during surgery and perform the surgery smoothly. The surgical target for endoscopic surgery is, for example, an organ, organ, or tissue such as the liver, stomach, large intestine, or uterus. The liquid suction system 100 includes a liquid suction tool 1 and an aspirator 5. The aspirator 5 is a device that includes a piston pump or an inflow prevention device, etc., and performs suction by generating negative pressure. The aspirator 5 may be capable of switching between suction and non-suction by turning on and off the power, and may also be capable of adjusting the strength of suction.

[0013] Fig. 2 is a diagram showing an example of the configuration of the liquid suction device 1 according to the embodiment. The liquid suction device 1 includes a tube 10 and a sponge body 20. The tube 10 is inserted into the body of the patient 60 via a trocar 51 placed on the body surface 70 of the patient 60 (see Fig. 4). The sponge body 20 is connected to one end 11 of the tube 10. The suction device 5 is connected to the other end 12 of the tube 10 and sucks the inside of the tube 10 from the other end 12. The method for connecting the sponge body 20 to the one end 11 of the tube 10 may be any method, and the sponge body 20 may be connected to the tube 10 and fixed as an integrated unit by, for example, sewing with thread or pasting with a seal or glue.

[0014] The tube 10 may be a general medical tube made of polyurethane, polyamide, silicon, or the like. The tube 10 is flexible. The sponge body 20 is made of a foamed synthetic resin such as polyurethane foam, and has a liquid-absorbing property capable of absorbing a liquid 80 (see FIG. 6) generated in the body of the patient 60, and an elasticity capable of easily deforming in the body and preventing damage to an organ 40 (e.g., the liver) or tissue. The size of the sponge body 20 may be determined according to the size of the surgical target and the surgical instrument 30. In the liquid-suction device 1, an X-ray-opaque marker 25 for indicating the position of the surgical site is attached to the sponge body 20 via a string, for example. The liquid-suction device 1 may be a disposable instrument. The liquid 80 generated in the body of the patient 60 includes water and blood. The liquid 80 may include liquid from tissues in the body and liquid introduced into the body from outside the patient 60 (e.g., water, cleaning liquid, medicine, and other liquids).

[0015] 3 is a diagram showing a configuration example of a tube 10 connected to a sponge body 20. The tube 10 has at least one hole 13 on one end 11 side. The tube 10 may have a plurality of holes 13 formed at the tip and side surface on the one end 11 side. The sponge body 20 is connected to the one end 11 side of the tube 10 and surrounds the one end 11 side of the tube 10. In this case, the tube 10 may be inserted inside the sponge body 20, so that the sponge body 20 surrounds the one end 11 side of the tube 10.

[0016] FIG. 4 is a diagram showing an example of the positional relationship of the surgical instruments 30, 31 and the liquid suction tool 1 with respect to the patient. The surgical instruments 30, 31 include forceps and the like. The surgical instruments 30, 31 advance into the inside of the patient 60 by, for example, inserting trocars 50, 51. The surgical instruments 30, 31 are operated, for example, by the surgeon. The forceps are used for various treatments (for example, grasping, resection, dissection, suturing) on ​​the organ 40 or tissue. The camera is operated so that the organ 40 or tissue to be operated on is included in the imaging range. The image captured by the camera is displayed, for example, on a monitor in the operating room. The surgeon can appropriately move or operate the surgical instruments 30, 31 by checking the organ 40 or tissue to be operated on the monitor. The inside of the patient 60 may or may not be insufflated. The number of trocars 50, 51 and the number of surgical instruments 30, 31 may not be two, but may be three or more. At least one of the surgical instruments 30 and 31 is a forceps and at least one is a camera. The inner diameter of the trocars 50 and 51 is, for example, about 10 mm.

[0017] In addition, in FIG. 4, the tube 10 of the liquid suction device 1 is inserted through a trocar 51, and the sponge body 20 of the liquid suction device 1 is placed inside the body. The sponge body 20 can be moved to any position inside the body by, for example, being gripped by the surgical instruments 30, 31 and being moved in a gripped state. The sponge body 20 can absorb the liquid 80 by being placed in an area in the body where a liquid 80 such as water or blood (see FIG. 6) exists. The liquid suction device 1 may be inserted into the body through the trocar 50, or may be inserted into the body through another trocar (for example, a trocar through which the surgical instrument 30 is not inserted and through which only the liquid suction device 1 is inserted). When the liquid suction device 1 is placed inside the body, the sponge body 20 can be discharged outside the body through the trocar 50 by, for example, pulling out the tube 110 from the body by the surgeon, that is, the liquid suction device 1 can be taken out of the body.

[0018] Next, the flow of liquid suction and delivery by the liquid suction device 1 will be described with reference to Figs.

[0019] Fig. 5 is a diagram showing a state in which a surgical instrument 30 and a liquid suction tool 1 are inserted into the body of a patient 60 during endoscopic surgery. The surgical instruments 30, 31 and the liquid suction tool 1 are inserted into the body of the patient 60 through trocars 50, 51 installed in holes provided on a body surface 70 of the patient 60. Fig. 5 shows a surgery in which a part of tissue of an organ 40 is excised using forceps as the surgical instrument 30.

[0020] Fig. 6 shows a state in which blood oozes out after a part of the tissue of the organ 40 is cut with forceps as the surgical instrument 30 after the state in Fig. 5. Such liquid 80 containing blood is desirable to be removed promptly because it hinders the surgery. In addition, liquids such as water, cleaning liquids, or chemicals may be sprayed onto the cut organ 40 or tissue, and it may be desirable to remove such liquid 80 promptly in order to ensure visibility of the surgical field.

[0021] Fig. 7 is a diagram showing a state in which, after the state in Fig. 6, the liquid suction device 1 is moved to a predetermined area in the body where liquid 80 including blood is present, using forceps as the surgical instrument 31, and the sponge body 20 is absorbing the liquid 80. At the timing in Fig. 7, the sponge body 20 is absorbing the liquid 80, but the delivery of the liquid 80 through the tube 10 has not yet started.

[0022] Fig. 8 is a diagram showing a state in which liquid 80 absorbed by sponge body 20 is discharged to the outside of the body via tube 10 after the state in Fig. 7. Aspirator 5 continuously performs suction inside tube 10 from the other end 12 of tube 10, and draws liquid 80 absorbed by sponge body 20 as liquid 80A from hole 13 at one end 11 of tube 10. Thus, tube 10 can prevent liquid 80 absorbed by sponge body 20 from accumulating in sponge body 20 for a long period of time, and can discharge it to the outside of the body as liquid 80A.

[0023] 6 to 8, the liquid suction device 1 can continuously absorb liquid 80 containing water, blood, etc., while the surgeon operates the surgical instruments 30, 31, etc. to perform a predetermined treatment on the organ 40 or tissue that is the subject of surgery. When absorbing liquid continuously, the liquid suction by the sponge body 20 and the liquid delivery by the tube 10 may be performed continuously or continuously, and the liquid 80A may move continuously or continuously inside the tube 10 and be discharged outside the body.

[0024] In the liquid suction tool 1 according to this embodiment, the tube 10 and the sponge body 20 are connected, and the surgeon can operate the surgical instruments 30, 31 to move the tube 10 and the sponge body 20 together, so that the liquid suction tool 1 can be easily operated. In addition, in endoscopic surgery, unlike open surgery, it is not possible to directly approach the area inside the body where the liquid 80 has accumulated, and it is necessary to move the liquid suction tool 1 from the position of the trocars 50, 51 to the area to be suctioned, and even suctioning the liquid 80 can be difficult. In contrast, in the liquid suction tool 1, the surgeon can move the tube 10 together by moving the sponge body 20, so that the complexity involved in operating the surgical instruments 30, 31 can be reduced. In addition, since the sponge body 20 covers one end 11 of the tube 10, the sponge body 20 serves as a buffer material, and even if the surgeon presses the tube 10 against the organ 40, etc., the organ 40 can be prevented from being damaged.

[0025] In addition, the liquid suction device 1 can absorb the liquid 80 accumulated in front of the organ 40, for example, by absorbing the liquid 80 with the sponge body 20, and can prevent the liquid 80 from interfering with the observation of the surgical site, making it easier for the surgeon to work. In this case, when the sponge body 20 becomes wet with the liquid 80, the liquid 80 can be continuously absorbed little by little due to the action of surface tension. Then, the liquid suction device 1 can continuously drain the liquid 80 absorbed by the sponge body 20 from the tube 10. Therefore, the liquid suction device 1 can reduce the amount of liquid in the sponge body 20 by sending the liquid 80 absorbed by the sponge body 20 to the tube 10, thereby preventing a decrease in the liquid suction performance of the sponge body 20. Therefore, the surgeon can leave a reserve capacity for the sponge body 20 to absorb liquid, even if the sponge body 20 is not replaced every time it is used for suction. Therefore, the liquid suction device 1 can maintain the liquid suction function of the sponge body 20 while absorbing a certain amount of liquid with the sponge body 20, while reducing the frequency of replacement of the sponge body 20 during surgery. In this way, the liquid suction device 1 can continuously absorb fluids from within the body while reducing the complexity of operations involved in endoscopic surgery, thereby enabling smooth surgery.

[0026] 3, the tube 10 may have a plurality of holes 13, for example, on at least one of the tip and side surface of one end 11 of the tube 10. In this case, since the tube 10 has a plurality of holes 13, even if one hole 13 becomes clogged with residue or solid matter, the liquid suction device 1 can continue suctioning through the other holes 13, thereby improving the reliability of the surgery.

[0027] Fig. 9 is a diagram showing another example of the arrangement of the plurality of holes 13 in the tube 10. As shown in Fig. 9, the plurality of holes 13 may include, for example, a plurality of holes 13 provided on the side surface of one end 11 of the tube 10 facing in different directions. The plurality of holes 13 provided facing in different directions may be, for example, a plurality of holes 13 provided around the circumference of the tube 10, and the holes 13 may be arranged at any position in the circumference. This enables the liquid absorbing device 1 to absorb liquid from a plurality of directions, thereby improving the liquid absorbing efficiency.

[0028] Fig. 10 is a diagram showing a modified example of the liquid suction device 1. In this example, a radiopaque marker 26 is provided on one end 11 side of the tube 10, integrally with the one end 11. There is no need to provide a radiopaque marker 25 separate from the tube 10 and the sponge body 20 as in Figs. 1 and 2, which simplifies the configuration and allows surgery to be performed more smoothly. The radiopaque marker 26 can be formed, for example, by applying radiopaque ink to the one end 11 of the tube 10.

[0029] Endoscopic surgery may include surgery by a surgeon or surgery by a surgical support robot. In the case of surgery by a surgeon, the surgeon operates the surgical instrument 30 and the liquid suction tool 1 in Figs. 5 to 8. In the case of surgery by a surgical support robot, the surgical support robot operates the surgical instrument 30 (end effector) and the liquid suction tool 1 in Figs. 5 to 8. The liquid suction tool 1 according to the embodiment can be used in both endoscopic surgery by a surgeon and endoscopic surgery using a surgical support robot.

[0030] When adjusting the suction force (amount of suction), the aspirator 5 may adjust the suction force taking into consideration the amount of air sent for pneumoperitoneum. For example, if the aspirator 5 performs excessive suction through the tube 10 of the liquid suction tool 1, the pneumoperitoneum may become insufficient and the abdomen of the patient 60 may shrink, which may affect the procedure related to the surgery. For example, the liquid suction system 100 may include a pressure sensor installed in the trocars 50, 51, etc. In this case, the aspirator 5 may balance the amount of suction and the amount of air sent, and adjust the amount of suction so that the pressure detected by the pressure sensor becomes a constant pressure.

[0031] Thus, according to the liquid suction device 1 of this embodiment, the tube 10 and the sponge body 20 are connected, and the surgeon can move the tube 10 and the sponge body 20 together, making it easy to operate the liquid suction device 1. In addition, since the sponge body 20 covers one end 11 of the tube 10, the liquid suction device 1 can avoid pressing the tube 10 against the organ 40 and damaging the organ 40. In addition, even if the organ 40 around the tube 10 is sucked when the liquid suction device 1 sucks through the tube 10, the sponge body 20 acts as a buffer material and can prevent the organ from being damaged. In addition, since the liquid suction device 1 can continuously drain the liquid 80 absorbed by the sponge body 20 from the tube 10 to the outside of the body, the moisture of the sponge body 20 can be reduced and the deterioration of the liquid suction performance of the sponge body 20 can be suppressed. In this way, the liquid suction device 1 and the liquid suction system 100 can continuously absorb liquid in the body while reducing the complexity of the operations related to endoscopic surgery, making it possible to perform smooth surgery.
