Description

Technical Field

[0001] This disclosure relates to a medical anchoring device for surgical procedures, its operation method, and its medical anchoring system. In particular, it relates to a medical anchoring device for minimally invasive surgery and / or gasless surgery, its operation method, and its medical anchoring system. Prior Technology

[0002] Videoscopic technique was developed in the 1980s. Later, due to advancements in camera and computer technology, these devices were gradually miniaturized. Furthermore, minimally invasive surgery (MIS) instruments have advanced rapidly since 2000. Minimally invasive surgery can now perform an increasing number of advanced surgical procedures, often with the aid of videoscopy.

[0003] When performing minimally invasive surgery (MIS), surgeons need to create space within the cavity before the procedure. With cavitation, the surgeon gains a field of vision and provides space for instruments. Traditionally, cavitation is created by inflating the cavity with carbon dioxide. Surgeons typically need to set up multiple air seal ports to accommodate various instruments and procedures.

[0004] Later, more and more surgeons reduced or even eliminated incisions in the abdomen or chest when performing minimally invasive surgery. However, maintaining an air seal in the body cavity after incision remains a major challenge. Over the past decade, single-site (LESS) endoscopes have been developed, all capable of limiting air leakage. However, due to their structural design, each has its own limitations. Furthermore, none of them can inflate the body cavity without carbon dioxide inflation. Consequently, none can serve as a stable fit point for surgical instruments.

[0005] Furthermore, when using a single-port endoscope, since all instruments and the endoscope are installed in the same hole, surgeons must endure the discomfort of instrument collisions, limited freedom of movement, and obstructed field of vision.

[0006] Of course, carbon dioxide inflation technology has been thoroughly validated as a safe technique for performing minimally invasive surgery. However, high-pressure carbon dioxide inflation has long been associated with a significant increase in blood carbon dioxide levels. Moreover, some literature demonstrates a risk of poor patient prognosis. Furthermore, when using carbon dioxide inflation technology, aspiration during surgery can lead to body cavity collapse. This is quite troublesome for surgeons.

[0007] Based on the above, the existence of a gasless technique that allows for effective expansion of body cavities could solve several major problems. Considering this unmet need, several medical devices have been developed. For example, some inventions focus on how to use an umbrella-like structure, introduced from the outside via a working port and opened within the cavity, to elevate the abdominal wall. The design concept is to open a lifting device that is as robust and wide as possible to maximize the lifting surface. A very similar idea is mentioned in US application 20080234551 A1, which uses hooks and wires applied to an open surgical incision for lifting. However, this solution is not perfect because the lifting position depends on the incision location, which greatly limits the lifting effect.

[0008] This invention aims to address potential problems using a gasless surgical system that may include a multi-task adapter with adjustable anchoring capabilities. It should be understood that this anchoring device allows the surgeon to obtain a controllable and adjustable stable connection point on the cavity wall. This not only facilitates cavity expansion but also provides docking points other than the single-port endoscope. More importantly, the surgeon may not need a single-port endoscope and may be able to perform natural orifice transluminal endoscopic surgery (NOTES). Connection points on the wall may also be applicable.

[0009] Figure 1 is a cross-sectional view of the abdominal cavity. The entire abdominal cavity is filled with internal organs, including the liver 701, left kidney 704, right kidney 702, spleen 705, and stomach 706 within the abdomen 700. Figure 1 also shows the location of the spine 703. As shown in Figure 1, there is no space between the abdomen and the internal organs, therefore the surgeon has no space to observe or manipulate surgical instruments.

[0010] Figure 2 depicts the distended abdominal cavity (peritoneal space). As shown in Figure 2, due to gravity, the internal organs are located at the bottom of the peritoneal cavity 712. The space between the internal organs and the distended abdomen 711 facilitates surgical procedures.

[0011] Figure 3 illustrates the conventional method of achieving an inflated abdominal cavity using pneumatic cannula trocars 720, 730, and 740 and carbon dioxide inflation. As shown in Figure 3, carbon dioxide is delivered into the abdominal cavity via tubing of the pneumatic cannula trocar (such as tubing 721 of pneumatic cannula trocar 720). The high-pressure carbon dioxide inflates the abdominal cavity and pushes the abdominal wall (abdomen) upwards, creating a carbon dioxide inflation space 750, allowing the procedure to continue. However, high-pressure carbon dioxide can dissolve in the blood and cause acidosis. Furthermore, maintaining abdominal distension is difficult under this pneumatic setup because aspiration can cause the inflated abdominal cavity to collapse. Summary of the Invention

[0048] Preferably, the connector 250 is detachably connected to the target object, so that the connector 250 can be removed from the target object and the cavity after surgery. Preferably, the connector 250 can be a clamping device configured to clamp the target object inside the target cavity (wherein the target object can be an organ or tissue or medical device inside the target cavity. For example, the target cavity can be the abdominal cavity, and the target object can be an organ inside the abdominal cavity). For example, the connector 250 can be a bulldog clamp, a non-traumatic clamp, or any other medical clamp, but is not limited thereto. It should be understood that the number of lead wires and puncture points can be provided as needed; for example, there can be two or more lead wires and puncture points.

[0049] Referring to Figure 6, a flowchart of one embodiment of a method for operating the medical anchoring device of the present invention is provided. As shown in Figure 5, the method 300 for operating the medical anchoring device begins at step 310, placing the anchoring device in a target cavity of the human body (such as the abdominal cavity, but not limited thereto). Preferably, the medical anchoring device may be placed in the target cavity using an endoscopic device, but is not limited thereto. The endoscopic device may be a laparoscopic clip applier, a bulldog clamp applier, a non-traumatic clip applier, or a non-traumatic clamp applier, but is not limited thereto. It should be understood that, as needed, the medical anchoring device may be placed in the target cavity using other devices or by other methods.

[0050] Next, step 320 is performed, in which the first puncture head punctures (penetrates) the first target location of the target cavity wall. Preferably, the first puncture head punctures from the inside of the target cavity to the outside of the target cavity. Preferably, the first puncture head can puncture the first target location of the cavity wall using an endoscope (e.g., the first puncture head is detachably connected to the endoscope, and the user (such as a surgeon) can control the endoscope to push the first puncture head to puncture the first target location), but is not limited thereto. It should be understood that, as needed, the first puncture head can puncture the first target location of the cavity wall using other devices or other methods. Next, step 330 is performed, in which the second puncture head punctures (penetrates) the second target location of the target cavity wall, wherein the first target location is different from the second target location. Preferably, the second puncture head punctures from the inside of the target cavity to the outside of the target cavity. Preferably, the second puncture site can puncture a second target location in the cavity wall using an endoscopic device (e.g., the second puncture site is detachably connected to the endoscopic device, and the user (such as a surgeon) can control the endoscopic device to push the second puncture site to puncture the second target location), but is not limited thereto. It should be understood that, as needed, the second puncture site can puncture the second target location in the cavity wall using other devices or other methods.

[0051] Next, step 340 is performed to connect the connector to the target object inside the target cavity. Preferably, the connector can be connected to the target object using an endoscopic device, but is not limited thereto. It should be understood that, as needed, the connector can be connected to the target object using other devices or other methods. Next, step 350 is performed to pull the first guide and / or the second guide (such as pulling the first end of the first guide and / or the third end of the second guide) to move the target object to the desired position or to the desired direction. Next, step 360 is performed, where the surgeon can decide whether it is necessary to change the target connection position of the connector, or whether there is a next target object that needs to be connected and controlled by the connector (step 360). If the answer to step 360 is yes, then step 340 is performed (and then steps 350 and 360 are performed again), whereby the surgeon can use the connector to connect to the next target connection position of the current target object or to connect to the next target object inside the target cavity. Otherwise, if there is no next target connection location that needs to be connected and controlled by the connector, and no next target object that needs to be connected and controlled by the connector, then step 370 is executed, where the use of the connector in the operation ends, and the surgeon can remove the connector and the lead wire from the target cavity. It should be understood that steps 340 to 360 form a loop, meaning that steps 340, 350, and 360 can be repeated until the answer to step 360 is no, and then step 370 is executed.

[0052] In one embodiment, when the use of the connector is finished and step 370 is performed, the surgeon can cut off all the leads from outside the target cavity and then remove the connector from the target cavity using any type of removal device (such as an endoscope). Preferably, the puncture head will not re-enter the target cavity during the connector removal procedure.

[0053] In one embodiment, the anchoring device may include a third guide portion and a third puncture portion, wherein the third puncture portion is connected to a fifth end of the third guide portion, and a sixth end of the third guide portion is connected to a connecting portion.

[0055] Please refer to Figure 7, which is a schematic diagram depicting the operation of a medical anchoring device according to one embodiment of the present invention. As shown in the embodiment of Figure 7, the connecting portion 450 of the medical anchoring device is placed in the abdominal cavity 820 of the human body, and the connecting portion 450 clamps the target organ 830 (the target organ 830 is the target object in this case) inside the abdominal cavity 820. The first puncture portion 430 with the first guide portion 410 punctures the first target position 812 of the cavity wall 810, the second puncture portion 440 with the second guide portion 420 punctures the second target position 814 of the cavity wall 810, and the third puncture portion 470 with the third guide portion 460 punctures the third target position 816 of the cavity wall 810.

[0056] With the medical anchoring device configured as shown in Figure 7, the surgeon can move the target organ 830 with the connecting part 450 to the desired position or direction by pulling the first guide part 410 and / or the second guide part 420 and / or the third guide part 460 and / or the first puncture part 430 and / or the second puncture part 440 and / or the third puncture part 470.

[0057] For example, a surgeon may move the target organ 830 with the connecting portion 450 to direction 910 by pulling the first guide portion 410 and / or the first puncture portion 430. Alternatively, a surgeon may move the target organ 830 with the connecting portion 450 to direction 920 by pulling the second guide portion 420 and / or the second puncture portion 440. Alternatively, a surgeon may move the target organ 830 with the connecting portion 450 to direction 930 by pulling the third guide portion 460 and / or the third puncture portion 470.

[0058] In one embodiment, after the puncture and guide segments pierce the target location in the cavity wall, each puncture segment can be replaced by an actuating device (such as another clamping device, gripper, or grasping device, but not limited thereto). Optionally, each guide segment can be connected to an actuating device, thereby allowing the surgeon to easily control the guide segments by operating the actuating device.

[0059] In one embodiment, after the connecting portion is connected to the target object or target organ, and the respective puncture portions connected to the corresponding lead portions have pierced the corresponding positions of the cavity wall, the user can connect each lead portion to the operating portion. Therefore, the operating portion can be used to control the length of the lead portions inside the cavity. For example, the operating portion can be a clamp device that clamps the lead portion and places it on the skin of the cavity; or the operating portion can be an electrical device that automatically or non-automatically controls the length of the lead portions inside the cavity by pulling or releasing the lead portions; or the operating portion can be a wire reel for controlling the length of the lead portions inside the cavity.

[0060] In one embodiment, at the end of use of the medical anchoring device, the surgeon can cut off all the lead portions (i.e., the first lead portion 410, the second lead portion 420, and the third lead portion 460 in FIG. 7), and then remove the connector from the target cavity using any type of removal device (such as an endoscopic device, but not limited thereto). Preferably, the puncture site will not re-enter the target cavity during the connector removal procedure.

As shown in the embodiment of Figure 8, the medical anchoring system 500 includes a medical anchoring device 510 (the structure and mechanism of the medical anchoring device 510 can be referred to above) and an endoscope device 520. The endoscope device 520 includes a handle portion 521, an actuating portion 524, a tube portion 526, and a control portion 522. The control portion 522 is connected to the tube portion 526 and is disposed at the end of the tube portion 526. The handle portion 521 is connected to the tube portion 526, and the actuating portion 524 is connected to the handle portion 521 and is movable or rotatable relative to the handle portion 521.

[0062] As shown in Figure 8, the medical anchoring device 510 is detachably connected to or housed in the control section 522 of the endoscope device 520. The surgeon can press the actuating part 524 of the endoscope device 520 to control the connecting part 515 of the medical anchoring device 510 to enter an open state (in the open state, the jaws of the connecting part 515 are open). Subsequently, the surgeon can control the connecting part 515 to contact a target object by operating and / or moving the endoscope device 520, and the surgeon can release the actuating part 524 of the endoscope device 520 to control the connecting part 515 of the medical anchoring device 510 to enter a closed state (in the closed state, the jaws of the connecting part 515 are closed) to connect the connecting part 515 to the target object. Simultaneously, the surgeon can use the endoscope device 520 to remove the connecting part 515 from the target object. Specifically, the surgeon can operate the endoscope device 520 to accommodate the connecting part 515 in the control section 522. Subsequently, the surgeon can press the trigger 524 to control the connection 515 of the medical anchoring device 510 to enter a first state (which may be referred to as the open state or the triggered state), so that the connection 515 can be easily and safely removed from the target object. Afterwards, the surgeon can remove the connection 515 from the target cavity by means of the control 522 of the endoscope device 520.

[0063] Preferably, the connecting portion 515 of the medical anchoring device 510 includes a jaw portion 515A and a pressing portion 515B, with the pressing portion 515B connected to the jaw portion 515A. When the surgeon presses the trigger portion 524, the control portion 522 applies pressing force to the pressing portion 515B, thus opening the jaw portion 515A based on the pressing force, and the connecting portion 515 enters a first state (which may be referred to as the open state or the triggered state). Simultaneously, when the surgeon releases the trigger portion 524, the control portion 522 stops applying pressing force to the pressing portion 515B, thus closing the jaw portion 515A and the connecting portion 515 enters a second state (which may be referred to as the closed state or the released state). Preferably, the jaw portion of the connecting portion forms a non-traumatic clamp or non-traumatic gripper that will not harm or damage the target object.

[0064] Preferably, the endoscope device 520 may have a rotational portion 528. The rotational portion 528 is disposed between the handle portion 521 and the tube portion 526, and the rotational portion 528 is rotatable relative to the handle portion 521 and the tube portion 526, wherein the control portion 522 rotates together with the rotational portion 528, so that the surgeon can operate (such as rotate) the rotational portion 528 to rotate the connection portion 515 to the desired angle.

[0065] In one embodiment, each puncture portion of the medical anchoring device 510 is detachably connected to the endoscope device 520. A surgeon can control the endoscope device 520 to puncture the cavity wall at a corresponding target location with each puncture portion. That is, as needed, the endoscope device can be configured such that a first puncture portion punctures a first target location in the cavity wall, and the endoscope device can be configured such that a second puncture portion punctures a second target location in the cavity wall. For example, the first puncture portion is detachably connected to the endoscope device, and a user (such as a surgeon) can control the endoscope device to push the first puncture portion to puncture the first target location. Similarly, the second puncture portion is detachably connected to the endoscope device, and a user (such as a surgeon) can control the endoscope device to push the second puncture portion to puncture the second target location. It should be understood that the third puncture site (if any), the fourth puncture site (if any), and other puncture sites (if any) can be used to puncture the corresponding target locations in the same manner as the first and second puncture sites.

[0066] Preferably, during the puncture procedure, at least a portion of the lead wire of the medical anchoring device 510 is housed within the tube 526 of the endoscope device 520. In another embodiment, at least a portion of each lead wire of the medical anchoring device 510 and / or each puncture portion is housed within the tube 526. The surgeon can manipulate the endoscope device 520 to push the puncture portion out of the tube 526 and allow the puncture portion to puncture the cavity wall.

[0067] It should be understood that, as needed, a medical anchoring system may include more than one medical anchoring device, allowing the surgeon to connect individual medical anchoring devices to different locations on the target object, or to different target objects. For example, the medical anchoring system may include a second medical anchoring device. The second medical anchoring device may include a fifth guide section, a sixth guide section, a fifth puncture section, a sixth puncture section, and a second connecting section. The fifth guide section may have a ninth and a tenth end, and the sixth guide section may have an eleventh and a twelfth end. The fifth puncture section is connected to the ninth end of the fifth guide section and configured to puncture the wall of the target cavity at a fifth target location. The sixth puncture section is connected to the eleventh end of the sixth guide section and configured to puncture the wall of the target cavity at a sixth target location, wherein the sixth target location is different from the fifth target location. The second connecting section is connected to the tenth end of the fifth guide section and the twelfth end of the sixth guide section, and is configured to connect to a first target object or a second target object inside the target cavity. Preferably, the endoscope is configured such that the fifth puncture portion punctures the fifth target position of the cavity wall, and the endoscope is configured such that the sixth puncture portion punctures the sixth target position of the cavity wall.

[0068] Please refer to Figures 9A-9C, which are schematic diagrams of a connecting portion according to one embodiment of the present invention. As shown in the embodiment in Figures 9A-9C, the connecting portion 600 includes a main portion 610, a first extension portion 620, a second extension portion 630, and a jaw portion 640, wherein the jaw portion 640 includes an upper jaw portion 642 and a lower jaw portion 644. The upper jaw portion 642 is connected to the first extension portion 620, and the lower jaw portion 644 is connected to the second extension portion 630. Preferably, the upper jaw portion 642 is formed as an annular shape, and the lower jaw portion 644 is also formed as an annular shape. It should be understood that the annular jaw portion can reduce damage to the target object when the jaw portion clamps the target object.

[0069] As shown in Figures 9B and 9C, the upper jaw portion 642 has a first jaw end 642A and a second jaw end 642B. The first jaw end 642A is connected to the first extension portion 620, and the second jaw end 642B is opposite to the first jaw end 642A. Simultaneously, the lower jaw portion 644 has a third jaw end 644A and a fourth jaw end 644B. ​​The third jaw end 644A is connected to the second extension portion 630, and the fourth jaw end 644B is opposite to the third jaw end 644A. Preferably, the thickness of the upper jaw portion 642 (referred to as the first thickness) gradually decreases from the first jaw end 642A to the second jaw end 642B, and the thickness of the lower jaw portion 644 (referred to as the second thickness) gradually decreases from the third jaw end 644A to the fourth jaw end 644B.

[0070] Preferably, the main portion 610 may have a plurality of protrusions (referred to as first protrusions) disposed on its outer surface. When the main portion 610 is connected to or housed in the control portion of the endoscope device, the plurality of protrusions of the main portion 610 will contact the control portion to increase the friction between the main portion 610 and the control portion, thereby ensuring that the main portion 610 is stably clamped by the control portion.
