Description

Technical Field

[0001] The present invention relates to a medical device; more particularly, the present invention relates to a medical device capable of performing suction, irrigation, and debridement without replacing instruments. Background Art

[0002] In traditional surgery, suction / irrigation devices are used to suck out contaminated fluids that reduce tissue visibility, and endoscopes and debridement devices are used to observe the interior of the tissue. These devices must be operated with both hands and must be changed frequently, making the surgeon's work quite complicated.

[0003] In addition, in order to perform cauterization, the debridement device or the suction / irrigation device must be removed before the cauterization device is inserted, which also makes the operation process more complicated for the surgeon.

[0004] Therefore, it is ideal to enable a single medical device to have the function of performing multiple tasks to reduce the frequency of surgeons changing surgical equipment and ensure the safety of patients undergoing surgery. Summary of the Invention

[0005] The object of the present invention is to provide a medical device that is convenient for surgeons to operate and has a safe activation mechanism.

[0006] The present invention provides a medical device, comprising an outer tube, an operating part and a control part. The outer tube extends along a first direction and has a first end and a second end opposite to each other. At least a portion of the operating part is located inside the outer tube and protrudes outside the second end of the outer tube. The control part has a channel and a first end and a second end opposite to each other and connected through the channel, and the second end of the control part is coupled to the first end of the outer tube so that the channel and the outer tube are connected to each other along the first direction. The control part includes a control module, and the control module includes a suction control part, a suction port actuator and a switch unit. The suction control part has a stop portion facing the channel and is movably arranged along a second direction different from the first direction. The suction port actuator and the suction control part are located on opposite sides of the channel and are driven by the suction control part. The switch unit is configured to be releasably driven by the suction control part to switch the working state of the operating part.

[0007] When the suction control portion is located at the first position, the control module stops the suction port actuator from sucking in the channel and causes the switch unit to stop the operation portion.

[0008] When the suction control portion is located at the second position, the control module enables the suction port actuator to perform suction in the channel.

[0009] When the suction control portion is located at the third position, the control module enables the suction port actuator to actuate suction in the channel, and drives the switch unit to enable the operating portion to actuate, and the stopping portion at least partially extends into the channel.

[0010] In one embodiment, when the suction control portion is located at the second position, the control module opens a suction valve to start suction in the channel.

[0011] In one embodiment, when the suction control portion is located at the second position, at least a portion of the stop portion extends into the channel, and the stop portion extends into a first depth of the channel. When the suction control portion is located at the third position, the stop portion extends into a second depth of the channel, and the second depth is greater than the first depth.

[0012] In one embodiment, the stopper has a baffle with a recess formed on the back side of the baffle. When the suction control portion is in the first position, at least a portion of the stopper extends into the channel and is switched between the first state and the second state by rotating the suction control portion. The control portion has a first handle end and a second handle end opposite to each other. In the first state, the baffle blocks at least a portion of the channel.

[0013] Furthermore, in the second state, at least a portion of the space enclosed by the recessed portion is connected to portions of the channel located on both sides of the stopping portion.

[0014] In one embodiment, in the first state, the baffle faces one of the first end of the handle and the second end of the handle, and the recess faces the other of the first end of the handle and the second end of the handle, and in the second state, at least a portion of the space generated between the recess and the baffle overlaps with the channel.

[0015] In one embodiment, in the first state, the suction control portion is movable between the first position and the third position in the second direction, and in the second state, the suction control portion is movable between the first position and the second position in the second direction.

[0016] In one embodiment, the suction control portion further includes a protrusion toward the switch unit, wherein in the first state, the protrusion and at least a portion of the switch unit are collinear in the second direction, and in the second state, the protrusion and the switch unit are not collinear in the second direction.

[0017] In one embodiment, the protrusion has a trapezoidal structure.

[0018] In one embodiment, the control module further includes: a flushing control portion movably disposed along the second direction; and a flushing port actuator located on an opposite side of the channel from the flushing control portion and enabled by the flushing control portion to perform flushing in the channel.

[0019] In one embodiment, the device further comprises an external instrument, at least a portion of which is located between the at least one suction control portion and the suction port actuator.

[0020] In one embodiment, the device further includes: an image capturing unit located at the portion of the operating portion protruding from one end of the outer tube; and a display operably coupled to the image capturing unit to receive the image captured by the image capturing unit and display the image.

[0021] In one embodiment, the control module further includes a motor electrically connected to the switch unit via a cable. When the suction control portion is located at the third position, the switch unit activates the motor to switch the operating portion to an operating state.

[0022] In one embodiment, the device further comprises an introducer having an introducer first end and an introducer second end that are opposite to each other and open, wherein at least a portion of one end of the outer tube protrudes from the introducer second end.

[0023] In one embodiment, the diameter of the channel is larger than the diameter of the external device and is less than 8 times the diameter of the external device.

[0024] In one embodiment, the diameter of the channel is twice the diameter of the external device.

[0025] In one embodiment, the diameter of the channel is between 1.0 mm and 4.0 mm.

[0026] In one embodiment, the diameter of the external device is greater than 0.5 mm and smaller than the diameter of the channel.

[0027] In one embodiment, the diameter of the external device is between 0.5 mm and 2.0 mm.

[0028] Through the above configuration, a single medical device can perform multiple tasks, especially debridement and blood aspiration at the same time, so as to ensure good visibility during the operation. In addition, by setting a combination of a stop part and an external device, the suction control part can be restricted from moving from the second position to the third position.

[0091] Various embodiments are described below, and those skilled in the art should readily understand the spirit and principles of the present invention by referring to the detailed description and accompanying drawings. However, while specific embodiments are described herein, these embodiments are intended to be illustrative only and are not intended to be limiting or exhaustive in any respect. Therefore, various variations and modifications of the present invention should be readily apparent and achievable by those skilled in the art without departing from the spirit and principles of the present invention.

[0092] See also Figure 1A and Figure 1B , Figure 1A and Figure 1B They are respectively an exploded view of an embodiment of the medical device 1 of the present invention and a plan view of the internal structure. Figure 1A and Figure 1BAs shown, the medical device 1 of the present invention includes an outer tube 10, an operating portion 20, a control portion 30 and a housing 40. The outer tube 10 is arranged in a manner extending along a first direction D1 and has a first outer tube end 10A and a second outer tube end 10B relative to each other. When the medical device 1 is in use, the first outer tube end 10A is relatively facing the operator, and the second outer tube end 10B is relatively away from the operator. The operating portion 20 is arranged inside the outer tube 10 in a manner protruding from the second outer tube end 10B. Therefore, when the medical device 1 is in use, at least a portion of the operating portion 20 is located inside the outer tube 10 to perform operations such as resection and debridement on the surgical target. For example, in this embodiment, the operating portion 20 may include a blade for debridement.

[0093] In this embodiment, at least a portion of the control unit 30 is located within the housing 40. The control unit 30 has a first handle end 30A and a second handle end 30B that oppose each other. When the medical device 1 is in use, the first handle end 30A and the second handle end 30B face toward and away from the operator, respectively. A channel 31 is formed between the first handle end 30A and the second handle end 30B, connecting the first handle end 30A and the second handle end 30B. The second handle end 30B is coupled to the first end 10A of the outer tube, connecting the channel 31 and the outer tube 10 along a first direction D1.

[0094] As described above, the control unit 30 includes a control module 300. Specifically, in this embodiment, the control module 300 includes at least a suction control unit 310, a suction port actuator 320, a switch unit 330, a flushing control unit 340, and a flushing port actuator 350. The suction control unit 310 and the flushing control unit 340 are adjacent to each other and movable along a second direction D2. The switch unit 330 is electrically connected to the operating unit 20 to switch the operating state of the operating unit 20 (e.g., to activate or deactivate the operating unit 20). The second direction D2 is a direction different from the first direction D1, such as, for example, a direction perpendicular to the first direction D1, but is not limited thereto. The movement paths of the suction control unit 310 and the flushing control unit 340 intersect with the channel 31. The suction port actuator 320 and the flushing port actuator 350 are located on opposite sides of the channel 31 from the suction control unit 310 and the flushing control unit 340 , respectively, and perform suction and flushing in the channel 31 through the suction control unit 310 and the flushing control unit 340 , respectively.

[0095] Next, see Figure 2A 、 Figure 2B and Figure 2C , Figure 2A 、 Figure 2B and Figure 2CSchematic cross-sections of a portion of the control unit 30 when the suction control unit 310 is located at a first position, a second position, and a third position in one embodiment of the medical device of the present invention, wherein the first position, the second position, and the third position are collinear along the second direction D2 and sequentially approach the channel 31. In this embodiment, as Figure 2A 、 Figure 2B and Figure 2C As shown, the suction control unit 310 has a stopper 311 facing the channel 31 (for example, along the second direction D2) and a protrusion 312 protruding in a direction different from the stopper 311 (for example, along the first direction D1). The protrusion 312 is preferably colinear with at least a portion of the switch unit 330 along the second direction D2; in other words, the switch unit 330 is located on the path of movement of the protrusion 312. Thus, the switch unit 330 can be releasably driven by the suction control unit 310 to switch the working state of the operating unit 20. When the suction control unit 310 moves to the third position ( Figure 2C ), at least a portion of the protrusion 312 contacts or presses the switch unit 330, thereby activating the switch unit 330.

[0096] Specifically, in this embodiment, when the suction control unit 310 is located at the first position ( Figure 2A ), the control module 300 stops the suction port actuator 320 from sucking in the channel 31 and simultaneously stops the switch unit 330 from actuating the operating unit 20. For example, in the present embodiment, the suction control unit 310 is configured to be at least partially located in the first channel P1 extending along the second direction D2, and includes an upper O-ring 313, a lower O-ring 314, and an extension portion 315 located between the upper O-ring 313 and the lower O-ring 314 and movable along the first channel P1. The upper and lower ends of the extension portion 315 are respectively connected to portions where the upper O-ring 313 and the lower O-ring 314 are provided, so as to link the movement of the upper O-ring 313 and the lower O-ring 314. In addition, the portion of the extension portion 315 that passes through the channel 31 can be designed to be concave to one side or to avoid the channel 31 to maintain the unobstructed passage of the channel 31. When the suction control unit 310 is in the first position ( Figure 2A ), the upper O-ring 313 and the tube wall of the first channel P1 are kept in close contact; at the same time, the lower O-ring 314 and the tube wall of the first channel P1 are also kept in close contact, so as to keep the suction valve 321 (composed of the lower O-ring 314 and the tube wall of the first channel P1) of the suction port actuator 320 in a closed state, thereby stopping the suction action in the channel 31.

[0097] When the suction control unit 310 is in the second position ( Figure 2B), the control module 300 enables the suction port actuator 320 to actuate the suction in the channel 31. For example, the control module 300 enables the suction control unit 310 from the first position ( Figure 2A ) moves to the second position ( Figure 2B ), open the suction valve 321 to start the suction action, and when the suction control unit 310 is from the second position ( Figure 2B ) moves to the first position ( Figure 2A ), the suction port actuator 320 stops the suction operation by closing the suction valve 321. Figure 2A ) moves to the second position ( Figure 2B ), since the width of the wall of the first passage P1 below the passage 31 widens toward the suction port actuator 320, as the extension portion 315 moves downward, the seal between the lower O-ring 314 and the wall of the first passage P1 is gradually released, thereby opening the suction valve 321. On the other hand, the width of the portion of the first passage P1 above the passage 31 is relatively uniform, so when the suction control unit 310 is moved from the first position ( Figure 2A ) moves to the second position ( Figure 2B ), the upper O-ring 313 can maintain a close fit with the wall of the first channel P1. In this embodiment, when the suction control unit 310 is in the second position ( Figure 2B ), the stopper 311 may extend into the channel 31 to the first depth d1, but the present invention is not limited to this. Depending on the actual arrangement and position of the stopper 311, the stopper 311 may also be located outside the channel 31. Furthermore, the structural principle of the suction control unit 310 driving the suction port actuator 320 of the present invention is not limited to this. The suction port actuator 320 can be configured to open or close based on the position of the suction control unit 310.

[0098] In this embodiment, the flushing control unit 340 is disposed so that at least a portion thereof is located within the second passage P2, which extends parallel to the first passage P1 along the second direction D2. The flushing control unit 340 includes an upper O-ring 341, a lower O-ring 342, and an extension 343 positioned between the upper O-ring 341 and the lower O-ring 342 and movable along the second passage P2. The second passage P2 can have the same or similar structure to the first passage P1. Thus, while the upper O-ring 341 maintains a tight seal with the wall of the second passage P2, the relative position of the lower O-ring 342 to the wall of the second passage P2 changes as the extension 343 moves. When the lower O-ring 342 is in close contact with the wall of the second passage P2, the flushing port actuator 350 stops flushing in the passage 31. When the close contact between the lower O-ring 342 and the wall of the second passage P2 is released, the flushing port actuator 350 is enabled to flush in the passage 31. However, the design of the flushing control unit 340 and the flushing port actuator 350 of the present invention is not limited to this, and flushing systems of different designs may also be used.

[0099] As above, when the suction control unit 310 is in the third position (refer to Figure 2C ), the control module 300 enables the suction port actuator 320 to actuate suction in the channel 31, and drives the switch unit 330 to actuate the operating portion 20, and the stop portion 311 at least partially extends into the channel 31; in other words, when there is another instrument extending into the channel 31, the stop portion 311 will be blocked and cannot move downward, so that the suction control portion 310 cannot move to the third position. Further, in this embodiment, when the suction control portion 310 is in the third position (refer to Figure 2C ), the stopper 311 can extend into the second depth d2 of the channel 31, and the second depth d2 is greater than the first depth d1. Specifically, when the suction control unit 310 is moved from the second position ( Figure 2B ) moves to the third position ( Figure 2C ), the upper O-ring 313 can maintain a tight seal with the wall of the first passage P1, while the lower O-ring 314 is not in tight seal with the wall of the first passage P1. Therefore, the control module 300 can keep the suction valve 321 open. After at least a portion of the protrusion 312 contacts the switch unit 330, the switch unit 330 is driven to enable the operation unit 20 to operate. For example, Figure 1B and Figure 2A-2C As shown, the control module 300 may further include a motor 360 for providing power to the operating unit 20 and a cable 361 electrically connecting the motor 360 to the switch unit 330, so that when the suction control unit 310 is in the third position ( Figure 2C), the switch unit 330 activates the motor 360 to switch the operating unit 20 to the operating state. However, the structure of the suction port actuator 320 and the principle of driving the suction port actuator 320 or the switch unit 330 are not limited to this. For example, the motor 360 and the switch unit 330 can be wirelessly connected, or the switch unit 330 can be directly wirelessly connected to a driver within the operating unit 20, as long as the driving of the suction port actuator 320 or the switch unit 330 depends on the suction port actuator 320.

[0100] Accordingly, it is very convenient for surgeons to perform suction and debridement with a single suction port actuator 320 (for example, it can be a button protruding from the medical device 1), and the operation of the operating unit 20 is maintained while debridement is being performed. Therefore, even if bleeding occurs during surgery on the brain or other parts of the body, the blood can be quickly aspirated to ensure good visibility. In addition, since the suction control unit 310 has a stopper 311, it can prevent or reduce the possibility that the suction port control unit 310 is unexpectedly moved to the third position (for example, it can only be moved to the third position when the suction control unit 310 is pressed hard) and the operating unit 20 is activated, causing damage to the incision site or the inserted instrument. For further information, please refer to Figure 2D , Figure 2D FIG. 3 is a schematic diagram showing that the stopper 311 prevents the suction control unit 310 from moving from the second position to the third position in one embodiment of the medical device of the present invention. Figure 2D As shown, when the external instrument 50 is inserted into the channel 31 between the suction control portion 310 and the suction port actuator 320, if the suction control portion 310 is pressed down to move from the second position to the third position, the stop portion 311 will interfere with the inserted external instrument 50 and cannot move downward, thereby preventing the suction control portion 310 from freely moving to the third position. The relevant embodiments are further described below.

[0101] like Figure 3A and Figure 3B , Figure 3A is a schematic plan view of the internal structure of an embodiment of the medical device 1 of the present invention when an external external instrument 50 is inserted, and Figure 3B To prevent the suction control portion 310 from being moved from the second position (refer to Figure 2B ) moves to the third position (refer to Figure 2C ). Specifically, Figure 3AAs shown, the external instrument 50 can be, for example, a cautery device (electrocautery unit), and the length of the external instrument 50 is preferably greater than the length between the first end 30A of the handle and the second end 10B of the outer tube (i.e., greater than the entire length of the medical device 1 along the first direction D1). This allows the external instrument 50 to extend beyond the second end 10B of the outer tube to perform cautery and other procedures, while also allowing the operator to conveniently remove the external instrument 50 from the first end 30A of the handle. As described above, when the medical device 1 of the present invention is used in combination with the external instrument 50, it can simultaneously include suction, irrigation, debridement, and cautery functions to enhance surgical efficiency. However, the present invention is not limited to this. For example, the external instrument 50 is not limited to a cautery device (electrocautery unit), and in other embodiments, the irrigation control unit 340 and irrigation port actuator 350 may be omitted as needed. The medical device 1 of the present invention is not limited to the above configuration.

[0102] As above, please refer to Figure 3C and Figure 3D , Figure 3C and Figure 3D Figures 1 and 2 are rear views of an embodiment of the medical device 1 before and after insertion of an external instrument 50. Figure 3C As shown, in one embodiment of the present invention, the diameter DM1 of the channel 31 is between 1.0 mm and 4.0 mm, and as shown in FIG. Figure 3D As shown, the diameter DM2 of the external instrument 50 is greater than or equal to 0.5 mm and smaller than the diameter DM1. More specifically, the diameter DM2 is preferably between 0.5 mm and 2.0 mm. Under the premise that the diameter DM1 is between 1.0 mm and 4.0 mm, by inserting the external instrument 50 having a diameter DM2 greater than or equal to 0.5 mm, the stopper 311 can be limited to extend into the second depth d2 of the channel 31, thereby preventing the suction control portion 310 from moving from the second position (refer to FIG. Figure 2B ) moves to the third position (refer to Figure 2C Thus, when the suction operation is performed alone, by inserting the suction control unit 310 into the channel 31, it is possible to further prevent the accidental activation of the operating unit 20, which may cause damage to other parts or insertion of instruments. However, the present invention is not limited to this. For example, even if the diameter DM1 and the diameter DM2 are not within the above range, the suction control unit 310 can be limited from the second position (refer to Figure 2B ) moves to the third position (refer to Figure 2C ).

[0103] Specifically, the diameter DM1 of the channel 31 is preferably larger than the diameter DM2 of the external instrument 50 and is less than 8 times the diameter DM2 (i.e., diameter DM2 < diameter DM1 ≤ 8×diameter DM2). More preferably, the diameter DM1 is about twice the diameter DM2 (2×diameter DM2). When the diameters DM1 and DM2 meet the above relationship, the stopper 311 can be limited to extend into the second depth d2 of the channel 31, thereby preventing the suction control portion 310 from moving from the second position (refer to FIG. Figure 2B ) moves to the third position (refer to Figure 2C ).

[0104] As above, Figure 4A and Figure 4B , Figure 4A and Figure 4B They are respectively an exploded view and a three-dimensional schematic diagram of a modified embodiment of the medical device 1. Figure 4A and Figure 4B As shown, in this embodiment, the medical device 1 may optionally include an introducer 60, an image capture unit 70, and a display 80. The introducer 60 has an introducer first end 60A and an introducer second end 60B that are opposed to each other and open. When the medical device 1 is in use, the introducer first end 60A faces the operator (e.g., a surgeon) and the introducer second end 60B faces the patient undergoing surgery. The outer tube second end 10B is preferably configured so that at least a portion protrudes from the introducer second end 60B. The provision of the introducer 60 prevents the medical device 1 from colliding with patient tissue, etc., when inserted into the patient.

[0105] Furthermore, the image capture unit 70 can be, for example, a camera and is located at the portion of the operating unit 20 that protrudes from the second end 10B of the outer tube so as to capture images of the direction of introduction of the medical device 1. Furthermore, the display 80 is operably coupled to the image capture unit 70 so as to simultaneously receive and display the images captured by the image capture unit 70. By configuring the image capture unit 70 and the display 80, when the operator inserts the medical device 1, the operator can confirm the relative position between the medical device 1 and the patient's tissue.

[0106] In the above-described embodiment, the suction control unit 310 is moved in the second direction D2 to drive or stop the suction port actuator 320 and the switch unit 330 . However, in another embodiment, the suction control unit 310 may also be rotated.

[0107] like Figure 5As shown, in this embodiment, the suction control unit 310 can rotate. When the suction control unit 310 is in the first position (i.e., the suction is stopped and the switch unit 330 is turned off), it can be switched between the first state and the second state by rotating.

[0108] See also Figure 6A and Figure 6B , Figure 6A is a plan view of the suction control unit 310 of another embodiment of the medical device 1 of the present invention in the first position and in the first state, and Figure 6B FIG3 is a schematic plan view of the suction control unit 310 of another embodiment of the medical device 1 of the present invention in a third position. Similar to the aforementioned embodiment, the suction control unit 310 is configured so that at least a portion is located within the first passage P1 extending along the second direction D2 and includes an upper O-ring 313 and a lower O-ring 314. In this embodiment, a stopper 311A ​​is positioned between the upper O-ring 313 and the lower O-ring 314 and is movable within the first passage P1, replacing the extending portion 315 of the aforementioned embodiment. The upper and lower ends of the stopper 311A ​​are connected to the portions where the upper O-ring 313 and the lower O-ring 314 are located, respectively.

[0109] In this embodiment, when the suction control unit 310 is in the first position and in the first state ( Figure 6A ), it can be moved to the third position ( Figure 6B The suction control unit 310 also has a protrusion 312. The protrusion 312 may have a trapezoidal structure, for example. However, the shape of the protrusion 312 is not limited thereto. In the first state, the protrusion 312 is preferably collinear with at least a portion of the switch unit 330 in the second direction D2, so that when the suction control unit 310 moves along the second direction D2, the protrusion 312 contacts the switch unit 330 and drives the switch unit 330 (e.g., Figure 6B As shown, it reaches the third position).

[0110] like Figure 5 and Figure 6A As shown, the stopper 311A ​​has a baffle 311B, and a recessed portion 316 is formed on the back side of the baffle 311B. Figure 6A As shown, in the first state, the baffle 311B blocks at least part of the channel 31. Specifically, the baffle 311B can face the first end 30A of the handle and the second end 30B of the handle ( Figure 3A As shown) (here, the first end 30A of the handle is taken as an example), and the recessed portion 316 can face the first end 30A of the handle and the second end 30B of the handle ( Figure 3A As shown) in the other (here, the second end 30B of the handle is taken as an example), therefore, in the first state, the external instrument 50 ( Figure 3A The handle (as shown) is blocked by the baffle 311B in the channel 31 and cannot extend into the second end 30B of the handle.

[0111] like Figure 7A and Figure 7B , Figure 7A is a partial cross-sectional schematic diagram of the control unit 30 when the suction control unit 310 is located at the first position and in the second state in another embodiment of the medical device 1 of the present invention, and Figure 7B FIG. 1 is a plan view of another embodiment of the medical device 1 of the present invention when the suction control unit 310 is in the second position. In this embodiment, when the suction control unit 310 is in the first position and in the second state ( Figure 7A ), the suction control unit 310 can be moved to the second position ( Figure 7B ).

[0112] In the second state, at least a portion of the space enclosed by the recessed portion 316 communicates with the portion of the channel 31 located on both sides of the stop portion 311A. Preferably, at least a portion of the space generated between the recessed portion 316 and the baffle 311B overlaps with the channel 31, so that the external instrument 50 ( Figure 3A The protrusion 312 and the switch unit 330 are not collinear in the second direction D2. Therefore, even in the second state, the suction control unit 310 will not reach the third position (the position where the protrusion 312 and the switch unit 330 are in contact) when moving along the second direction D2. Figure 6B ), and reaches the second position ( Figure 7B shown).

[0113] In this embodiment, after inserting the external instrument 50 ( Figure 3A ), it is not possible to switch from the second state to the first state, and when the suction control unit 310 is switched from the second position ( Figure 7B ) moves to the third position ( Figure 6B ), it is necessary to first move the suction control unit 310 along the second direction D2 to the first position ( Figure 7A ) and then rotates from the second state to the first state and then moves along the second direction D2, so the external device 50 ( Figure 3A When performing the operation as shown) or performing the suction work alone, it further prevents accidents such as accidentally starting the operating part 20 and injuring the patient.

[0114] In summary, the medical device of the present invention, through the structure of the channel connecting to the operating unit, can simultaneously perform tasks such as debridement and blood drawing, thereby ensuring good visibility during surgery. Furthermore, when combined with an external device such as an electrocautery unit, while ensuring that the operating unit is deactivated, it is possible to perform both electrocautery and blood drawing simultaneously, or to perform blood drawing alone.
