Description

surgical devices

[0001] The present invention relates to a surgical device, and more particularly, to a surgical device that maximizes the efficiency of stone removal.

[0002]

[0003] In the past, open surgery, where the abdomen is incised and opened, was the standard procedure for intra-abdominal surgery. However, with the advancement of laparoscopy and miniature surgical instruments, laparoscopic surgery has become increasingly common for relatively simple procedures, such as cholecystectomy.

[0004] Laparoscopic surgery is a type of minimally invasive surgery that is performed by making multiple small incisions (incision points) in the abdomen. This minimizes damage to surrounding tissues and organs compared to conventional open surgery, and as a result, the post-operative recovery period and hospitalization period can be dramatically shortened.

[0005] Furthermore, the concept of non-invasive surgery, which does not require incisions at all, has recently been introduced, leading to the development of new surgical techniques such as Natural Orifice Transluminal Endoscopic Surgery (NOTES). This endoscopic technique utilizes endoscopic instruments inserted through natural openings such as the stomach, intestines, and vagina, allowing for the surgical procedure to be performed without external incisions.

[0006] Endoscopic surgical devices like these are used in a variety of surgical and surgical procedures, and more recently, they have been widely utilized for the non-invasive removal of stones formed within the kidneys and urinary tract. Typically, a stone removal endoscope (e.g., a flexible ureteroscope) is inserted into the ureter, the stone is broken up using a laser or other device, and the fragments are then removed using a basket-shaped collection tool.

[0007] However, the conventional technology has suffered from various inefficiencies in the process of collecting and discharging fragmented stones through a basket. In particular, after collecting the stone fragments using a basket, they must be passed through a flexible access tube (Ureteral Access Sheath, hereinafter referred to as "UAS") to be removed from the body, and then the basket must be re-inserted into the UAS to repeatedly collect and discharge them. This process was very cumbersome and time-consuming.

[0008] If multiple fragments remain after stone fragmentation, it is difficult to collect all fragments with a single basket. Therefore, the process must be repeated multiple times. This not only increases procedure time, but can also lead to various side effects, including operator fatigue, increased patient exposure, and increased risk of infection. Furthermore, the repeated insertion and ejection of the basket into the UAS increases the risk of basket damage and difficulty in accurately positioning it.

[0009]

[0010] The present invention has been devised to solve the above-mentioned problems, and its purpose is to provide a surgical device that maximizes the efficiency of stone removal.

[0050]

[0051] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. Prior to this, it should be noted that the terms and words used in this specification and claims should not be construed as limited to their conventional or dictionary meanings. Based on the principle that the inventor can appropriately define the concepts of terms to best explain his or her invention, they should be interpreted in a way that aligns with the technical spirit of the present invention.

[0052] Accordingly, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention, and it should be understood that there may be various equivalents and modified examples that can replace them at the time of this application.

[0053] FIG. 1 is a drawing showing a surgical device (10) according to one embodiment of the present invention, FIG. 2 is a cross-sectional view of the surgical device (10) of FIG. 1 taken along line AA', and FIG. 3 is a drawing exemplarily showing a state in which a stone (hereinafter referred to as a reference numeral 'S') is discharged to the outside through a stone removal unit (210) in the surgical device (10) according to one embodiment of the present invention.

[0054] Referring to FIGS. 1 to 3, a surgical device (10) according to one embodiment of the present invention may include a first part (100) and a second part (200).

[0055] The above first part (100) may include a main body (110) and a passageway (120).

[0056] The above main body (110) can constitute the appearance and overall shape of the first part (100).

[0057] The above passageway (120) may be provided inside the main body (110) and configured to guide the movement of the first tube (E) in the forward and backward directions. At this time, the first tube (E) may have a channel formed therein so that a stone capture unit (B) or a laser unit (not shown) may move forward and backward along the longitudinal direction of the first tube (E). In addition, the first tube (E) may be configured to be movable inside the human body by being provided with a separate driving means (not shown).

[0058] The second part (200) may be coupled to one end of the passageway (120). In addition, the second part (200) may include a stone removal part (210) and a passageway coupling part (220).

[0059] The above stone removal unit (210) can be configured to apply physical force or suction force to the stone capture unit (B) that captures stones inside the human body (e.g., inside the urinary tract or inside the kidney) while being driven forward and backward through the channel of the first tube (E), thereby separating stones from the stone capture unit (B).

[0060] For example, a stone may be a crystallized substance such as calcium inside the human body. In this case, the stone located inside the human body can be broken down by laser irradiation from the laser unit drawn into the body through the channel of the first tube (E).

[0061] At this time, the crushed stone is captured by the stone capture unit (B), and the stone capture unit (B) that has captured the stone is positioned to the second part (200) by the backward driving of the first tube (E) while in close contact with the tip of the first tube (E), and a physical force that expands the stone capture unit (B) is applied so that the stone captured inside falls freely, or the stone can be removed by applying a suction force to the stone capture unit (B) by a separate vacuum source (V).

[0062] Here, the passage connecting portion (220) may be configured to be connected to one end of the passage portion (120) in the stone removal portion (210).

[0063] In the case of conventional surgical devices, one of the methods for discharging crushed stones to the outside through a basket (corresponding to the stone capture unit (B) of the present invention) is to completely discharge the first tube (E) to the outside of the surgical device (or the outside of the second tube (T)) with the stones captured inside the basket to remove all stones, and then re-insert the basket together with the first tube (E) into the human body. However, in the case of this method, since the first tube (E) including the basket must be completely discharged to the outside, there is a problem that not only is the efficiency of stone removal reduced, but there is also a problem that buckling may occur when the first tube (E) re-enters.

[0064] On the other hand, the surgical device (10) of the present invention may be configured to separate the stone from the stone capturing portion (B) by applying a physical force or suction force to the stone capturing portion (B) in the stone removal portion (210) of the second part (200) without completely discharging the first tube (E) including the stone capturing portion (B) in which the stone is captured to the outside of the surgical device.

[0065] According to this embodiment of the present invention, stones can be efficiently removed without completely discharging the stone capturing portion (B) and the first tube (E).

[0066] And the second part (200) may include an exhaust part (230).

[0067] The above discharge unit (230) may be provided below the stone removal unit (210). In addition, the discharge unit (230) may be configured to discharge stones separated from the stone capture unit (B) downward.

[0068] In one embodiment, the stone removal unit (210) may be configured to dry the stone when applying suction to the stone capture unit (B). Stones removed from the body may have moisture around them and may not easily fall off or be removed due to surface tension. To solve this problem, in the process of removing stones by applying suction to the stone removal unit (210), drying and suction may be performed simultaneously through a separate drying means (not shown), such as a heating device, to remove moisture, thereby making it easier to remove the stone.

[0069] That is, the stone removal unit (210) can guide the stone to be better sucked toward the discharge unit (230) by applying suction force to the stone capture unit (B) and sucking the stone toward the discharge unit (230) while drying the surface of the stone to remove the surface tension of the stone.

[0070] In an embodiment of the present invention, a second tube (T) that accommodates a first tube (E) and is inserted into the human body may be connected to one end of the passageway (120). This second tube (T) may be configured to be bendable to correspond to the shape of the inside of the human body. In addition, the second tube (T) may be formed of a material with excellent elasticity and flexibility. For example, the second tube (T) may include a material such as silicone, urethane, or synthetic resin. In this case, the second tube (T) may be configured to be movable inside the human body by being provided with a separate driving means (not shown).

[0071] Here, the second tube (T) serves as a passage through which water irrigated by the kidney is discharged to the stone removal unit (210), and small stones are also discharged together with the discharged water to the outside through the discharge unit (230).

[0072] And, through the second tube (T), the movement of the first tube (E) in the forward and backward direction can be guided.

[0073] In one embodiment, the first portion (100) may further include a first tube insert (130).

[0074] The above first tube insertion portion (130) is provided at the other end of the passage portion (120), and the first tube (E) can be inserted.

[0075] In addition, the surgical device (10) may further include a sealing portion (300). As an example, the sealing portion (300) may include a material such as silicone or rubber.

[0076] The above sealing portion (300) can be coupled to the first tube insertion portion (130) to seal the other end of the passage portion (120).

[0077] FIG. 10 is a drawing showing a surgical device according to another embodiment of the present invention.

[0078] Compared to the surgical device (10) illustrated in FIG. 2, all components except the passage (130) that guides the movement of the first tube (E) in the first part (100) are omitted, and the sealing part (300) and the stopper part (500) can be configured in a form in which they are directly mounted on the second part (200).

[0079] That is, the surgical device may have a shape in which the first tube (E) is inserted directly from the first tube insertion portion (130) into the second tube (T) through the stone removal portion (210), without the main body (110) and passage portion (130) that constitute the appearance and overall shape of the first part (100).

[0080] In addition, if necessary, the stone removal unit (210) can be installed connected to a structure that fixes or moves the first tube (E) or the second tube (T).

[0081] Figure 4 is a drawing showing a surgical device (12) according to a second embodiment of the present invention.

[0082] Since the surgical device (12) according to the present embodiment is similar to the surgical device (10) according to the previous embodiment, duplicate descriptions of components that are substantially the same or similar to those of the previous embodiment will be omitted, and the following will focus on differences from the previous embodiment.

[0083] Referring to FIG. 4, in the surgical device (12), the stone removal unit (210) may be configured to have a diameter that becomes smaller as it goes downward.

[0084] That is, the stone removal unit (210) is configured in a shape that is tapered in the downward direction, so that stones removed through the stone removal unit (210) do not remain inside the second part (200) and can be quickly discharged to the outside. However, this is not limited to this, and the stone removal unit may be configured in a shape that is not inclined.

[0085] FIG. 5 is a drawing showing a surgical device (14) according to a third embodiment of the present invention, and FIG. 6 is a drawing showing a change in the state of a sealing part according to sliding operation.

[0086] Since the surgical device (14) according to the present embodiment is similar to the surgical device (10) according to the previous embodiment, duplicate descriptions of components that are substantially the same or similar to those of the previous embodiment will be omitted, and the following will focus on differences from the previous embodiment.

[0087] Referring to FIGS. 5 and 6, in the surgical device (14), the sealing portion (300) may further include a buffer portion (310).

[0088] The above buffer portion (310) may be configured to extend from the sealing portion (300) along the first tube insertion portion (130) toward the outer surface of the main body (110) and come into contact with the outer surface of the main body (110). In addition, the buffer portion (310) may be configured in a bellows shape.

[0089] The sealing portion (300) is configured to prevent a vacuum state from being maintained due to a gap occurring between the first tube insertion portion (130) and the corresponding stopper portion (500) being joined thereto, and to maintain a sealing state. In particular, the sealing portion (300) is configured in a bellows shape and has a buffer portion (310) configured to be in contact with the outer surface of the main body (110), thereby maintaining a more stable sealing state and at the same time minimizing the load due to the forward and backward movement of the first tube (E).

[0090] In addition, the surgical device (14) may include a base portion (140) positioned at the lower portion of the main body (110) and configured to slide the main body (110) in the forward and backward direction of the first tube (E) together with the first tube (E) at the upper portion thereof.

[0091] More specifically, the first tube (E) penetrates the sealing portion (300) and enters the first tube insertion portion (130), and the sealing portion (300) and the plug portion (500) described later are fixed to the base portion (140) and formed integrally with the base portion (140), and when the first tube (E) penetrates and is inserted into the plug portion (500) and the sealing portion (300) and moves in the front-back direction, the main body (110) slides together on the upper surface of the base portion (140).

[0092] Here, the base portion (140) may further include a force detection unit (150) that detects a load applied to the second tube (T) according to the movement of the first tube (E).

[0093] In addition, the force sensing unit (150) includes a load cell (151) installed in the base unit (140), and a pivot bar (153) having one end connected to the load cell (151) and the other end connected to the base unit (140), and the main body (110) may have a fitting groove (111) formed to engage the other end of the pivot bar (153) and rotate the pivot bar (153) according to a load applied to the main body (110) from the forward and backward movement of the first tube (E).

[0094] Specifically, the force sensing unit (150) provided in the base unit (140) is configured to measure the load caused by the forward and backward movement of the first tube (E) through the load cell (151). The load cell (151) is connected to the base unit (140) by a pivot bar (150), one end of which is hinge-joined to the load cell (151), the other end is fitted into the fitting groove (111) of the main body (110), and the center is hinge-joined to the base unit (140). Accordingly, the base (140) and the load cell (151) and the hinge-connected pivot bar (153) rotate according to the forward and backward movement of the first tube (E), and the load cell (151) measures the load. If the load measured by the load cell (151) is greater than a preset value (reference value), it is detected that there is a problem with the operation of the first tube (E), and the operation of the first tube (E) can be controlled.

[0095] Figure 7 is a drawing showing a surgical device (16) according to the fourth embodiment of the present invention.

[0096] Since the surgical device (16) according to the present embodiment is similar to the surgical device (10) according to the previous embodiment, duplicate descriptions of components that are substantially the same or similar to those of the previous embodiment will be omitted, and the following will focus on differences from the previous embodiment.

[0097] Referring to FIG. 7, in the surgical device (16), the sealing portion (300) may include a buffer portion (310).

[0098] Additionally, the sealing portion (300) may further include an auxiliary sealing portion (320).

[0099] The above auxiliary sealing portion (320) can be configured to surround the buffer portion (310) in the circumferential direction and pressurize the first tube insertion portion (130) in the radial direction.

[0100] That is, the auxiliary sealing portion (320) can additionally support the buffer portion (310) in the radial direction to minimize the load that can be transmitted to the inside of the human body during surgery by driving in the forward and backward direction through the passage portion (120) of the first tube (E) and the second tube (T).

[0101] Accordingly, the load inside the human body caused by the driving of the first tube (E) can be further minimized.

[0102] Figure 8 is a drawing showing a surgical device (18) according to the fifth embodiment of the present invention.

[0103] Referring to FIG. 8, the surgical device (18) may include a plug portion (500) and a first tube sealing portion (600).

[0104] The above plug (500) can surround the end of the first tube insertion portion (130) when the first tube (E) is inserted into the first tube insertion portion (130). In addition, the plug (500) can be configured to seal the outer surface of the first tube (E). As an example, the plug (500) can include a plastic material.

[0105] The first tube sealing portion (600) may be provided radially between one end of the plug portion (500) and the outer circumferential surface of the end of the first tube (E). In addition, the first tube sealing portion (600) may be configured so that a portion of the first tube (E) is inserted into the first tube insertion portion (130) when the first tube (E) is inserted into the first tube insertion portion (130).

[0106] In the case of conventional surgical devices, there was a problem in which the end of the first tube was bent by the plug for inlet sealing when the first tube was inserted.

[0107] On the other hand, in the case of the surgical device (18) of the present invention, when the first tube (E) is inserted into the first tube insertion portion (130), the first tube sealing portion (600) provided between one end of the plug portion (500) and the outer circumferential surface at the end of the first tube (E) in the radial direction can effectively seal the entrance of the first tube insertion portion (130) while preventing damage to the end of the first tube (E).

[0108] Figure 9 is a drawing showing a surgical device (20) according to the sixth embodiment of the present invention.

[0109] Referring to FIG. 9, the surgical device (20) may include a plug (510) provided on the outside of the plug portion (500).

[0110] Specifically, the plug portion (500) may be formed to extend from the main body (110) or the base portion (140) toward the first tube insertion portion (130) and may be mounted on the extension portion (160) on which the sealing portion (300) and the plug portion (500) are mounted. Here, the plug (510) may be provided on the outside of the plug portion (500), and preferably, a spiral-connecting portion (520) having a shape corresponding to the screw thread formed on the extension portion (160) may be formed to pressurize the plug portion (500) by spiral-connecting in the direction toward the first tube insertion portion (130).

[0111] At this time, as one end of the plug (500) pressurized by the plug (510), more precisely, one end of the plug (500) through which the first tube (E) is inserted, is pressurized, the diameter of the space into which the first tube (E) is inserted gradually expands, thereby minimizing resistance when the first tube (E) is inserted.

[0112]

[0113] Figures 11 and 12 are drawings showing a surgical device (22) according to the seventh embodiment of the present invention.

[0114] Referring to FIGS. 11 and 12, the surgical device (22) may include a distance adjustment unit (700).

[0115] The distance adjustment unit (700) may include a adjustment unit body (710), a support unit (720), a screw unit (730), a fixing unit (740), and a guide unit (750).

[0116] The above control unit body (710) may be configured to be connected to one end of the second tube (T).

[0117] The above support member (720) can grip a portion of the second tube (T) spaced a predetermined distance apart from one end of the second tube (T). In addition, the support member (720) can be configured to move in the forward and backward direction of the second tube (T). The support member (720) supports the second tube (T) at both ends of the position where the second tube (T) is gripped.

[0118] That is, the distance adjustment unit (700) may include an extension portion that extends parallel to the second tube (T) to one side of the main body (710), and the extension portion may be largely composed of a screw portion (730) and a guide portion (750).

[0119] The above screw thread portion (730) may be configured such that one end is drawn out from the control unit body (710) or inserted into the control unit body (710). In addition, the screw thread portion (730) may be configured such that the other end is coupled to the second tube gripper (720). By driving the screw thread portion (730), the support portion (720) may move in the forward and backward direction of the first tube (E).

[0120] The above-mentioned fixed part (740) is provided in the control part main body (710) and can be configured to maintain an adjusted state in which the length of the first tube (E) of the screw part (730) is drawn out from the control part main body (710) in the front-back direction or the length of the first tube (E) is drawn into the control part main body (710).

[0121] Specifically, the fixed part (740) may include a pressing part (742), an adjusting groove engaging part (744), and a screw engaging part (746).

[0122] The above pressing part (742) can move the fixed part (740) up and down inside the control part body (710) by external force. This pressing part (742) can be provided on the upper side of the fixed part (740).

[0123] The above-mentioned adjustment groove engaging portion (744) is provided in the above-mentioned fixed portion (740), and when the pressing portion (742) is pressed by an external force, the contact with the adjustment groove (712) formed in the adjustment portion main body (710) can be released. In this case, the fixing portion (740) can be moved downward within the adjustment portion main body (710).

[0124] In addition, the above-mentioned adjustment groove engaging portion (744) can come into contact with the adjustment groove (712) when the external force applied to the pressing portion (742) is released. In this case, the fixed portion (740) can move upwards within the adjustment portion body (710) and can be restricted from moving in the up-and-down direction by coming into contact with the adjustment groove (712).

[0125] The above screw thread engaging portion (746) is provided on the lower side of the fixing portion (740), and when the pressing portion (742) is pressed by an external force, it can move downward and release contact with the screw thread portion (730). In this case, the screw thread portion (730) can move in the forward and backward direction of the first tube (E), and maintain an adjusted state in which the length of withdrawal from the adjusting portion body (710) in the forward and backward direction of the first tube (E) or the length of introduction into the adjusting portion body (710) is adjusted.

[0126] In addition, when the external force applied to the pressing portion (742) is released, the screw thread engaging portion (746) moves upward again and comes into contact with the screw thread portion (730) to limit the movement of the first tube (E) of the screw thread portion (730) in the forward and backward direction.

[0127] The above guide part (750) can connect between the control part body (710) and the support part (720). In addition, the guide part (750) can be configured to guide the movement of the first tube (E) of the support part (720) in the forward and backward direction according to the length adjustment of the screw part (730).

[0128] By this implementation configuration, even if various types of second tubes (T) having different structures of one end of the second tube (T) are inserted, the distance between the support part (720) and the control part body (710) is adjusted, so that it can be driven stably.

[0129] Fig. 13 is a drawing showing a surgical device (24) according to the eighth embodiment of the present invention.

[0130] Since the surgical device (24) according to the present embodiment is similar to the surgical device (22) according to the previous embodiment, duplicate descriptions of components that are substantially the same or similar to those of the previous embodiment will be omitted, and the following will focus on differences from the previous embodiment.

[0131] Referring to Fig. 13, the surgical device (24) may further include a communication portion (F) formed on one side of the second tube (T) to communicate with the second tube (T). Water may be introduced (irrigated) or discharged (suction) through the communication portion (F), and other functions required for surgery may be performed.

[0132] In addition, the control unit body (710) includes a second tube coupling portion (711) to which one end of the second tube (T) is coupled, and the second tube coupling portion (711) may have one or more radially cut grooves (713) formed therein. The second tube coupling portion (711) may have a cone shape whose diameter gradually increases from one end to the other end so that the end of the second tube (T) is coupled thereto. In addition, one end of the second tube coupling portion (711) may have one or more radially formed cut grooves (713), so that the shape of one end of the second tube coupling portion (711) can be adjusted, so that second tubes (T) of various sizes or shapes can be coupled.

[0133] In addition, in the process of gripping the second tube (T) through the support (720), if too much force is applied, the second tube (T) may be twisted, and if too little force is applied, there is a problem that the second tube (T) is not stably gripped. Therefore, the outer surface of the second tube (T) can be pressed only as much as necessary through the spring (721) formed within the support (720). However, gripping of the second tube (T) by the support (720) made of a material having self-elasticity without using the spring (721) is also possible.

[0134] Fig. 14 is a drawing showing a surgical device (26) according to the ninth embodiment of the present invention.

[0135] Referring to FIG. 14, the surgical device (26) may be formed with a screw thread portion (730) instead of a guide portion (750) compared to the surgical device (22), and a pair of screw thread portions (730) may be arranged to face each other.

[0136] That is, the guide part (750) that guides the movement of the first tube (E) of the support part (720) in the forward and backward direction according to the adjustment of the length of the screw part (730) is replaced with another screw part (730), and the support part (720) can be moved in the forward and backward direction by adjusting the length of withdrawal or introduction through the fixing part (740) in each of the opposing pair of screw parts (730).

[0137] Fig. 15 is a drawing showing a surgical device (28) according to the tenth embodiment of the present invention.

[0138] Referring to FIG. 15, compared to the surgical device (26), the fixing part (740) of the surgical device (28) may be formed on the support part (720) rather than on the adjusting part body (710), and the support part (720) may be configured to be movable along the longitudinal direction of a pair of screw threads (730).

[0139] Specifically, a support portion (720) is formed so as to be movable, in which a fixing portion (740) is formed along the longitudinal direction of a pair of threaded portions (730) facing each other. Inside the support portion (720), a pressing portion (742), an adjusting groove engaging portion (744), and a thread engaging portion (746), which are detailed components of the fixing portion (740), may be formed, and a pair of fixing portions (740) may be formed at positions corresponding to the threaded portions (730) within the support portion (720) so as to adjust the length of each of the pair of threaded portions (730).

[0140] That is, the support member (720) can adjust the position at which the second tube (T) is held by adjusting the position on the screw member (730) through the fixing member (740) while simultaneously holding the second tube (T).

[0141] In addition, a pair of springs (748) described above are formed within the support member (720) to stably hold the second tube (T).

[0142] As described above, although the present invention has been described by limited embodiments and drawings, the present invention is not limited thereto, and various modifications and variations are possible by a person having ordinary skill in the art to which the present invention pertains within the scope of the technical idea of ​​the present invention and the equivalent scope of the patent claims to be described below.

[0143] Meanwhile, although terms indicating directions such as up, down, left, right, front, and back are used in the present invention, it is obvious to those skilled in the art that these terms are only for the convenience of explanation and may vary depending on the location of the target object or the location of the observer.
