Description

Adapter for endoscope port

[0001] The present invention relates to an adapter that can be installed in an endoscope port for performing an endoscope procedure, and more specifically, to an adapter for an endoscope port that adjusts the position of a surgical instrument inserted into the endoscope port.

[0002] Endoscopic surgical instruments are generally used for oral procedures using an endoscope. These endoscopic surgical instruments include a flexible, thin, and long moving body. The tip of the moving body, which is inserted into the body, is equipped with a treatment section for performing the procedure, and an operating section for manipulating the treatment section is installed on the external, withdrawable portion of the moving body.

[0003] Meanwhile, endoscopic surgical instruments such as lasers, snares, needles, and knives can be inserted through the working channel of a flexible endoscope. Here, laser surgery is performed by inserting a thin tube into the surgical site, inserting an endoscope into it, and directly viewing the lesion area. A snare is used to remove polyps using a snare, a needle is used to inject a specific drug into organic tissue, and a knife is used to cut a specific organic tissue such as a lesion.

[0004] Thanks to the advancement of endoscopy, new treatments using endoscopy are continuously being developed, and there is a need for the development of endoscopic devices suitable for these new treatments.

[0005] Endoscopic resection involves a variety of instruments, including lasers, injection needles, snares, and knives. These instruments are inserted into the endoscopic instrument channel to perform the procedure, and then replaced with other instruments for subsequent procedures or other procedures. In particular, the process of inserting a laser tube into the long, thin endoscopic instrument channel, then removing it, and then inserting a new tube requires significant time and effort.

[0006] In addition, since endoscopic surgical equipment is generally inserted and fixed in the instrument path during the procedure, it was difficult to finely adjust the position of the surgical equipment during the procedure.

[0007] The purpose of the present invention is to provide an adapter for an endoscope port that can finely adjust the position of a surgical instrument inserted into an endoscope port, and can simultaneously install a surgical instrument and a saline solution-supplying or suction-capable treatment instrument, thereby minimizing the time for an endoscopic procedure and effectively improving the effectiveness of the procedure.

[0038] Singular expressions include plural expressions unless the context clearly indicates otherwise.

[0039] In this application, each step described may be performed regardless of the listed order, except in cases where a special causal relationship requires that the steps be performed in the listed order.

[0040] In this application, terms such as “include” or “have” are intended to specify the presence of a feature, number, step, operation, component, part or combination thereof described in the specification, but should be understood not to exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

[0041] Hereinafter, the present invention will be described with reference to the attached drawings.

[0042] Referring to FIGS. 1 to 9, the adapter for the endoscope port of the present invention can adjust the position of a surgical instrument inserted into the endoscope port, and allows the surgical instrument and the treatment instrument for supplying saline solution to be installed simultaneously, thereby minimizing the endoscopic surgical time and effectively improving the surgical effect.

[0043] First, an example in which an adapter for an endoscope port according to the present invention is mounted on an endoscope port will be described in detail with reference to FIGS. 1 and 2.

[0044] An adapter (100) for an endoscope port according to an embodiment of the present invention may be formed to be detachable from an endoscope port (50) into which a surgical instrument is inserted. The endoscope port (50) into which the adapter (100) for an endoscope port is mounted may be, for example, a surgical device for an upper gastrointestinal endoscopy, but may alternatively be one of various devices for endoscopic procedures.

[0045] Here, the endoscope port (50) is described as an example in which it is installed in a T-shaped structure, but the endoscope port (50) may be either a straight or T-shaped, and the structure of the endoscope port (50) is not limited to the present embodiment.

[0046] According to an embodiment, the adapter (100) for an endoscope port enables fine adjustment of the position of a surgical instrument inserted into the adapter (100) for an endoscope port. To this end, the adapter (100) for an endoscope port includes a main pipe (130) into which a surgical instrument is inserted and a position adjustment means (150, 160) for the surgical instrument is provided, and a branch pipe (140) branched from the main pipe (130) and into which saline solution is injected.

[0047] As illustrated in FIG. 3, a port insertion tube (198) inserted into an endoscope port (50) may be formed at one end of the main pipe (130), and a coupling cap (190) screw-connected to the endoscope port (50) may be mounted. In addition, a hollow movable body (120) may be inserted and mounted at the other end of the main pipe (130) so that a surgical instrument may be inserted therethrough and may be reciprocally moved a certain distance by a position adjusting means (150, 160). A gripper (170) for selectively holding a surgical instrument may be mounted inside the movable body (120), and a control valve (146) for controlling the saline solution flow rate may be mounted at the branch pipe (140).

[0048] Referring to FIGS. 2 to 4 to examine specific features of the main pipe (130) according to the embodiment, the moving body (120) is provided with a mounting protrusion (123) so that a gripper (170) can be mounted therein, and a pressure cap (110) is screw-connected to one end thereof. To this end, a first screw thread (122) may be formed at one end of the moving body (120), and a second screw thread (112) may be formed on the pressure cap (110) to be coupled with the first screw thread (122) of the moving body (120).

[0049] The pressure cap (110) has a hollow shape so that a surgical instrument can be inserted through it, and a pressure projection (113) is formed that can pressurize the gripper (170) while the pressure cap (110) is screwed onto one end of the moving body (120). That is, the pressure projection (113) is formed long on the lower side of the pressure cap (110) and can be seated on the upper part of the gripper (170). In the process of the pressure cap (110) being screwed onto one end of the moving body (120), the pressure projection (113) can press the upper part of the gripper (170), and in this process, the gripper (170) can be selectively pressed (see (a) of FIG. 9).

[0050] The gripper (170) has a hollow shape so that a surgical instrument can be penetrated and inserted, and can be selectively pressed by a pressing projection (113) formed on the lower side of the pressing cap (110) during the process of screwing the pressing cap (110) to one end of the moving body (120). At this time, the shape of the gripper (170) may be partially deformed in a direction perpendicular to the direction in which the pressing projection (113) presses the gripper (170) (in the embodiment, in the up and down direction) (in the embodiment, in the left and right direction). As the shape of the gripper (170) is partially deformed, a surgical instrument inserted and mounted within the gripper (170) can be fixed in position by the gripper (170).

[0051] The settling jaw (123) is a position where the gripper (170) is settling within the moving body (120). Specifically, the gripper (170) can be settling on the lower end of the moving body (120). To this end, the upper inner diameter of the moving body (120) can be formed to be larger than the lower inner diameter based on the lower end of the moving body (120). In other words, the lower inner diameter of the moving body (120) is formed to be smaller than the upper inner diameter of the moving body (120) so that the gripper (170) is placed on the settling jaw (123) which is the upper part of the lower end of the moving body (120).

[0052] The position adjustment means (150, 160) provided in the main pipe (130) is for finely adjusting the position of the surgical instrument fixed to the gripper (170). To this end, the position adjustment means (150, 160) includes a rack gear part (126) formed on the outer surface of the moving body (120), and a position adjustment lever (160) having a pinion gear part (166) that is rotatably connected to the main pipe (130) and connected to the rack gear part (126). The distance at which the rack gear part (126) of the moving body (120) and the pinion gear part (166) of the position adjustment lever (160) engage each other can be the distance at which the moving body (120) reciprocates.

[0053] At this time, the position control lever (160) includes a pivot shaft portion (164) that is axially coupled to a coupling opening (150) formed on the main pipe (130) and a handle portion (162) that extends from the pivot shaft portion (164), and a pinion gear portion (166) may be formed on the pivot shaft portion (164). That is, the pivot shaft portion (164) is fitted into the coupling opening (150), and when the handle portion (162) rotates, the pinion gear portion (166) and the rack gear portion (126) are engaged, and the moving body (120) can reciprocate a certain distance.

[0054] According to an embodiment, a moving body (120) is inserted into a main pipe (130), and a pressure cap (110) is screw-connected to one end of the moving body (120) to pressurize a gripper (170) so that the surgical instrument can be fixed within the moving body (120). At this time, as shown in (a) and (b) of FIGS. 9A and 9B, when the handle part (162) is rotated in the direction in which the moving body (120) is inserted (in the example, in the up and down direction), the position of the meshed rack gear part (126) can be changed as the pinion gear part (166) rotates. As the position of the meshed rack gear part (126) with the pinion gear part (166) is changed, the moving body (120) can move slightly in the direction opposite to the direction in which it is inserted.

[0055] As illustrated in FIGS. 7 and 8, the position adjustment lever (160) may be formed with a stopper portion (168) that limits the rotation range of the pinion gear portion (166). Correspondingly, as illustrated in FIG. 5, a pair of catches (158a, 158b) may be formed in the coupling opening (150) of the main pipe (130) on which the stopper portion (169) can be caught when the position adjustment lever (160) is rotated.

[0056] The stopper part (169) can limit the range of rotation of the pinion gear part (166), and the stopper part (169) can be used to restrict the continued rotation of the pinion gear part (166) by stopping the pinion gear part (166) while it is rotating.

[0057] In addition, a catch (158) is formed at the end of the coupling opening (150), and when the pinion gear part (166) rotates, it can engage with the stopper part (169) to stop the rotation of the pinion gear part (166).

[0058] Referring again to FIGS. 4 and 5, a wide-diameter flange portion (132) may be formed at the other end of the main pipe (130) to accommodate the pressure cap (110) during the reciprocating movement of the moving body (120). Specifically, the flange portion (132) accommodates the pressure cap (110) when the pressure cap (110) is screw-connected to one end of the moving body (120), thereby preventing the pressure cap (110) screw-connected to one end of the moving body (120) from being loosened or damaged by rotating in the opposite direction to the coupling direction.

[0059] Meanwhile, in order to prevent the saline solution supplied through the branch pipe (140) from leaking through the main pipe (130), a first O-ring (R1) may be mounted between the insertion tube (138) formed at one end of the main pipe (130) and the coupling cap (190), and a second O-ring (R2) may be mounted on the moving body (120) inserted into the other end of the main pipe (130).

[0060] Referring to FIG. 5, the first O-ring (R1) can be mounted on the insertion tube (138) to prevent the saline solution supplied through the branch pipe (140) from leaking into the joint portion where the insertion tube (138) of the main pipe (130) is mounted.

[0061] When saline water is supplied through the branch pipe (140), the second O-ring (R2) may cause the saline water to flow back between the main pipe (130) and the moving body (120). The backflowed saline water may leak through the gap between the main pipe (130) and the position adjusting means (150, 160). In order to prevent such leakage of saline water, the second O-ring (R2) is mounted on the moving body (120) to prevent the saline water from flowing between the main pipe (130) and the position adjusting means (150, 160). In order to mount the second O-ring (R2) on the moving body (120) in this way, an O-ring mounting portion (124) may be formed on the other end of the moving body (120).

[0062] Referring again to FIGS. 4 and 5, in the case where the endoscope port (50) is a double-pipe type in which a surgical instrument conduit and a saline solution conduit are formed on the branch pipe (140) (see Example 50 of FIG. 1), a closing cap (180) for closing the saline solution conduit (52) is screwed on.

[0063] Specifically, it is connected to the end of the branch pipe (140), and when necessary, it can be separated from the end of the branch pipe (140) to block the saline water pipe (52) and prevent additional supply of saline water to the saline water pipe (52). In addition, when saline water is supplied to the branch pipe (140), the saline water pipe (52) can be closed to prevent external dust from entering the saline water pipe (52).

[0064] The control valve (146) of the branch pipe (140) can limit the flow rate of the saline solution supplied to the branch pipe (140) by blocking or opening the inside of the branch pipe. To this end, the control valve (146) can be rotatably installed in the branch pipe (140), and can limit the flow rate of the saline solution supplied by allowing the inside of the tubular branch pipe (140) to be communicated through rotation or blocking the inside of the branch pipe (140).

[0065] A valve installation portion (142) in which a control valve (146) is installed is formed in the branch pipe (140), and the control valve (146) and the valve installation portion (142) can be hook-coupled. To this end, a first coupling portion (148) can be formed at one end of the control valve (146), and a second coupling portion (144) coupled with the first coupling portion (148) can be formed inside the valve installation portion (142).

[0066] In this way, when adjusting the position of the surgical instrument through the control valve (146), the flow rate of saline solution supplied to the branch pipe (140) is limited, and the inflow and supply of saline solution to the main pipe (130) is blocked.

[0067] In the embodiment, the branch pipe (140) is described as an example of limiting the supply of saline solution, but alternatively, a pressure pump may be installed in the branch pipe (140) to automatically perform suction. At this time, the control valve (146) is open while suction is in progress, and when suction is to be stopped, the control valve (146) is closed to stop the suction.

[0068] According to an embodiment of the present invention, in addition to a saline solution supply, another surgical instrument can be inserted through a branch pipe, and an adapter for an endoscope port according to another embodiment of the present invention will be described in detail with reference to the drawings below.

[0069] Referring to FIGS. 10 to 12, an adapter for an endoscope port according to another embodiment of the present invention can insert another surgical instrument in addition to a saline solution supply through a branch pipe, and the main pipe into which the surgical instrument is inserted is configured to selectively hold the surgical instrument and to finely adjust the position of the inserted surgical instrument.

[0070] Before going into a detailed description of the drawings, if the configuration of the adapter (100A) for an endoscope port according to another embodiment of the present invention described in FIGS. 10 to 12 is the same as the configuration of the adapter (100A) for an endoscope port according to an embodiment of the present invention described in FIGS. 1 to 9, a detailed description will be omitted.

[0071] An adapter (100A) for an endoscope port according to another embodiment of the present invention may include a main pipe (130) into which a surgical instrument is inserted and a branch pipe (140) branched from the main pipe (130) and into which another surgical instrument is inserted.

[0072] In another embodiment of the present invention, a port insertion tube (198) inserted into an endoscope port may be formed at one end of a main pipe (130) of an adapter (100A) for another endoscope port, and a coupling cap (190) screw-connected to the endoscope port may be mounted.

[0073] In addition, a hollow movable body (120) can be inserted and mounted at the other end of the main pipe (130) so that the surgical instrument can be inserted through it and can move back and forth a certain distance by a position adjustment means (150, 160).

[0074] To this end, a first gripper mounting portion (175A) is mounted on one end of the moving body (120), on which a first gripper (170A) that selectively holds a surgical instrument is mounted, and a first pressure cap (110A) that is screw-connected to one end of the first gripper mounting portion (175A) can be mounted so as to selectively apply pressure to the first gripper (170A).

[0075] Specifically, the first gripper mounting member (175A) may be formed in a structure that is screw-connected to one end of the moving body (120) or may be formed in a structure that is integrally formed with one end of the moving body (120). In the present invention, an example in which the first gripper mounting member (175A) is formed in a screw-connected structure will be described below.

[0076] In other words, referring to FIGS. 11 and 12, when the first gripper mounting member (175A) is structured to be screw-connected to one end of the moving body (120), a first-first coupling screw thread (125) may be formed on one end of the moving body (120) to be screw-connected with the first gripper mounting member (175A), and a first-second coupling screw thread (179A) may be formed inside one end of the first gripper mounting member (175A) to be screw-connected with the first-first coupling screw thread (125). In addition, a first-fourth coupling screw thread (112A) may be formed inside the first pressure cap (110A) to be coupled with a first-third coupling screw thread (177A) formed on the outer surface of the other end of the first gripper mounting member (175A).

[0077] At this time, the first gripper mounting hole (175A) may be formed in a hollow shape so that a surgical instrument may be inserted through it, and the first gripper (170A) may be mounted inside it. Similarly, the first pressure cap (110A) may be formed in a hollow shape so that a surgical instrument may be inserted through it.

[0078] When a first gripper mounting portion (175A) is mounted inside the first pressurizing cap (110A) and is screw-connected to the moving body (120), the first gripper (170A) can be pressurized. To this end, the first pressurizing cap (110A) may include a first gripper pressing portion (113A) that is formed inside the first pressurizing cap (110A) and is in contact with the upper portion of the first gripper (170A) and can press the upper portion of the first gripper (170A) mounted on the first gripper mounting portion (175A).

[0079] In the process of screw-connecting the first pressure cap (110A) to the first gripper mounting hole (175A), the first gripper (170A) can be selectively pressed by the lower portion of the pressure cap (110A) that pressurizes the upper portion of the first gripper (170A). The shape of the first gripper (170A) can be partially deformed in a direction (in the embodiment, left and right directions) perpendicular to the direction in which the first pressure cap (110A) presses the first gripper (170A) (in the embodiment, up and down directions). As the shape of the first gripper (170A) is deformed, the position of the surgical instrument inserted and mounted in the first gripper (170A) is fixed.

[0080] Referring again to FIGS. 11 and 12, another surgical instrument can be inserted and mounted into one end of the branch pipe (140), and the position of the other surgical instrument can be fixed using a gripper so that it is fixed to the branch pipe (140). To this end, the branch pipe (140) may have a hollow second gripper mounting hole (175B) screw-connected thereto, a second gripper mounting hole (175B) screw-connected thereto, and a second gripper (170B) for selectively holding another surgical instrument may be mounted inside the second gripper mounting hole (175B). At this time, the second pressure cap (110B) screw-connected to one end of the second gripper mounting hole (175B) can selectively pressurize the second gripper (170B).

[0081] As illustrated, the branch pipe (140) is formed by branching from the main pipe (130), and another treatment device can be inserted and mounted into the branch pipe (140). In this case, in another embodiment, the structure into which another treatment device is inserted and mounted may be the second pressure cap (110B), the second gripper mounting hole (175B), and the second gripper (170B).

[0082] In another embodiment, the second pressure cap (110B), the second gripper mounting portion (175B), and the second gripper (170B) may be formed as one of a structure that is integrally formed at one end of the branch pipe (140) or a structure that is screw-joined and detachable, and in another embodiment of the present invention, a screw-joined structure will be described as an example.

[0083] According to an embodiment, a second-first coupling thread (145) may be formed at one end of the branch pipe (140) to be screw-connected with a second gripper mounting hole (175B), and a second-second coupling thread (177B) may be formed inside one end of the second gripper mounting hole (175B) to be screw-connected with the second-first coupling thread (145).

[0084] Additionally, the second pressure cap (110B) may have a hollow shape so that another surgical instrument can be inserted through it and may include a second-fourth coupling screw thread (112B) that is screw-connected to a second-third coupling screw thread (179B) formed at the other end of the second gripper mounting hole (175B).

[0085] That is, according to another embodiment of the present invention, a second gripper mounting portion (175B) may be mounted by screwing to one end of the branch pipe (140). When the second gripper (170B) is mounted to the second gripper mounting portion (175B), a second pressure cap (110B) may be screwed to one end of the second gripper mounting portion (175B). When the second pressure cap (110B) is screwed to one end of the second gripper mounting portion (175B), the second pressure cap (110B) selectively pressurizes the upper end of the second gripper (170B) while fixing the position of another surgical instrument inserted and mounted in the branch pipe (140).

[0086] The technical features disclosed in each embodiment of the present invention are not limited to that embodiment, and, unless they are mutually incompatible, the technical features disclosed in each embodiment may be combined and applied to different embodiments.

[0087] Therefore, although each embodiment focuses on its own technical features, each technical feature can be applied in combination with each other as long as they are not mutually incompatible.

[0088] The present invention is not limited to the above-described embodiments and the attached drawings, and various modifications and variations are possible within the scope of those skilled in the art. Therefore, the scope of the present invention should be defined not only by the claims of this specification but also by equivalents thereof.
