Description

Single-port surgical training device and surgical training method thereof

[0001] The present disclosure relates to a single port surgical training device and a surgical training method thereof.

[0002]

[0003] Transanal surgery, a type of minimally invasive surgery, involves inserting a cylindrical instrument through the anus without making an abdominal incision, and performing local resections while viewing the area on a monitor connected to a camera. Another type of minimally invasive surgery, laparoscopic surgery, involves making a small incision in the abdomen, inserting a laparoscope with a special camera attached, and using specialized instruments such as lasers or special surgical techniques. These minimally invasive surgeries were developed to overcome the shortcomings of conventional open surgery, which involves making large incisions, causing significant scarring, bleeding, and prolonged recovery times.

[0004] These minimally invasive surgeries offer advantages such as smaller incisions, less scarring and bleeding, a much shorter recovery time compared to open surgery, and significantly less postoperative pain. Currently, they are used for nearly all conditions requiring open surgery. However, the long-term training required to master the techniques through extensive hands-on experience makes acquiring minimally invasive surgery a challenge.

[0005] In response to this, various types of surgical training simulators have been developed, but conventional minimally invasive surgical training simulators are implemented with monotonous devices such as dolls, and thus have the disadvantage of being one-time use or lacking realism.

[0006]

Furthermore, in the description of various embodiments below, duplicate descriptions of identical or corresponding components may be omitted, but this does not mean that the corresponding components are not included in the embodiments.

[0057] FIG. 1 is an exemplary diagram of a single port surgical training device (100) according to the present disclosure, and FIG. 2 is an exemplary diagram of a simulation module and surgical tool for single port surgical training according to the present disclosure.

[0058] The surgical training device (100) according to the present disclosure is a single-port based surgical training device consisting of one port, and includes a surgical tool, a simulation module (110), and a host computer. The single-port surgical training device (100) can be utilized for the purpose of allowing medical staff to gain experience and train while practicing single-port surgery (or minimally invasive surgery), such as transanal surgery, thoracoscopic surgery, and laparoscopic surgery, for example.

[0059] Single-port surgery has the advantage of being more stable than multi-port surgery and of not requiring an incision. However, single-port surgery has the disadvantage of being more difficult than multi-port surgery because multiple surgical instruments are inserted into a single port, and two or more surgical instruments must not overlap each other. Furthermore, even experienced surgeons sometimes find it difficult to perform single-port surgery. The single-port surgery training device (100) according to the present disclosure is a device for training single-port surgery and can simulate an actual surgical environment similar to that of a real surgical environment.

[0060] A surgical instrument according to one embodiment may include forceps, a cutting tool, and at least one first sensor. The forceps may be a type of forceps, a type of surgical instrument or device used in a surgical field, such as a surgical instrument or device, and may be a type of surgical instrument having a scissor-shaped, bifurcated end and a handle connected thereto. The cutting tool may be a type of surgical instrument capable of making incisions. The at least one first sensor may be a sensor configured to generate positional information and posture information of at least one of the forceps and the cutting tool.

[0061] As illustrated in FIGS. 1 and 2 , a single-port surgical training device (100) may include a simulation module (110) for simulating surgery on a subject. The simulation module (110) is provided with a single port (120) (hereinafter, referred to as a single port). A user (e.g., a doctor or medical student) may hold and manipulate surgical tools. For example, the user may hold forceps (130) and a cutting tool (140) in both hands and insert them into the interior of the simulation module through the single port (120).

[0062] In one embodiment, the single port (120) may be formed with at least two injection ports, each capable of inserting a plurality of surgical instruments. For example, as illustrated in FIG. 2 , first to third injection ports (122, 124, 126) may be formed in the single port (120), and forceps (130) and a cutting tool (140) may be inserted into the first and second injection ports (122, 124), respectively. Additionally, an endoscopic camera or additional forceps (e.g., counter forceps) may be inserted into the third injection port (126).

[0063] As illustrated in FIGS. 1 and 2 , a single port (120) may be formed to penetrate one side wall of the housing of the simulation module (110). A cannula (128) may be provided inside the single port (120) so that a surgical tool may be inserted therein. The cannula (128) may be made of a material having elasticity similar to that of a human organ (e.g., silicone). The surgical tool may touch the inner surface of the cannula (128), and a user using the single-port surgical training device (100) may feel as if it is touching an actual human organ.

[0064] A target (220) that mimics a specific part of an object (e.g., a human body) may be placed within the simulation module (110). The target (220) may correspond to a specific part, such as a tumor to be removed during a surgical procedure. The user may use a surgical tool to grasp and incise the target (220).

[0065] According to one embodiment, a plurality of second sensors (210) may be provided inside the simulation module (110). The plurality of second sensors (210) may be provided inside the housing of the simulation module (110). The plurality of second sensors (210) may detect surgical tools inserted into the interior of the simulation module (110). The plurality of second sensors (210) may track the surgical tools inserted into the interior of the simulation module (110), thereby measuring the position and posture of the surgical tools. In addition, the plurality of second sensors (210) may also measure the relative position of the surgical tools with respect to the target (220), whether there is contact, whether there is an incision, etc. For example, the plurality of sensors (210) may be arranged in the housing of the simulation module (110), the target (220), etc. Instead of the plurality of sensors, a vision device such as a camera (212) may be used, or it may be used together with a vision device.

[0066] The host computer according to the present disclosure can process information received from the simulation module (110) and / or the surgical tool to generate virtual reality information. The host computer can receive information on the position and posture of the surgical tool received from the simulation module, information on the relative position of the surgical tool with respect to the target (220), whether contact has been made, whether incision has been made, etc., and can receive information on the position of the forceps (130) and the incision tool (140) and / or the relative position information between the two surgical tools from the surgical tool. The host computer can process this information to generate virtual reality information by visualizing the surgical tool approaching a specific organ in an actual object and a specific part (e.g., a tumor) in the specific organ. The virtual reality information can be output through the display (150) of the host computer or the display of a separate VR device, and the user can perform surgical training while viewing the virtual reality information output on the display (150).

[0067] Although FIG. 1 illustrates one embodiment of outputting virtual reality information through a display, the present disclosure is not limited thereto. In one embodiment, virtual reality information may also be output through a display of a VR device (not shown) worn by a user. In this case, the virtual reality information may be displayed from the perspective of the user wearing the VR device (or from the camera view of the VR device). This embodiment has the advantage of improving training efficiency because the user can experience the perspective of an actual surgeon.

[0068] The single-port surgical training device (100) according to the present disclosure can enhance the user's sense of reality by providing a training environment for single-port surgery to users, such as medical staff. In particular, since multiple surgical tools must be inserted through a single port (120) to perform movements such as grasping or cutting a target (220), friction or collisions between the multiple surgical tools can frequently occur. The device can be trained on how to deal with such situations or how to prevent such situations from occurring.

[0069] Figure 3 is a configuration diagram of a single port surgical training device (100) according to the present disclosure.

The processor (314) may execute software (e.g., a program) to control at least one other component (e.g., a hardware component, a software component) connected to the processor and perform various data processing or calculations. As at least part of the data processing or calculations, the processor (314) may load instructions or data received from other components into the memory (316), process the instructions or data stored in the memory (316), and store the resulting data in the non-volatile memory (316). The memory (316) of the processor (314) may store information related to the above-described method or store a program in which the above-described method is implemented. The memory (316) may be a volatile memory or a non-volatile memory.

[0079] A processor (314) according to one embodiment can execute a program. The code of the program executed by the processor (314) can be stored in the memory (316).

[0084] A simulation module (110) according to one embodiment may include a housing (not shown), a single port (120) provided on one side of the housing and configured to allow forceps (130) and a cutting tool (140) to be inserted, and at least one second sensor (210) provided inside the housing. The at least one second sensor (210) may include at least one of a vision sensor, an optical sensor, or a camera sensor. The at least one second sensor (210) may detect whether a surgical tool (320) is inserted into the single port (120) of the simulation module (110). The at least one second sensor (210) may track location information of the surgical tool (320) inserted into the single port (120). The at least one second sensor (210) may be positioned at a location where the single port (120) is clearly visible.

[0085] According to one embodiment, a marker for position tracking may be inserted into the surgical tool (320). For example, a marker implemented in a specific pattern may be inserted into the gripper of the forceps (130) of the surgical tool (320). At least one second sensor (210) may irradiate light to the marker and receive light reflected from the marker, thereby confirming position information and posture information of the forceps (130). Similarly, a marker may be formed on the cutting tool (140) or the endoscope camera (324) of the surgical tool (320), so that at least one second sensor (210) may track position information and posture information of the cutting tool (140) or the endoscope camera (324).

[0086] In the same manner as described above, at least one second sensor (210) can also track position information and attitude information of a target (220) placed within the simulation module (110).

[0087] FIG. 4 is a flowchart illustrating a surgical training method according to one embodiment of the present disclosure. For surgical training, a user may hold a surgical tool (320) in his or her hand and insert the surgical tool (320) into the simulation module through the single port (120) of the simulation module. For example, the user may hold the handle of a forceps (130) in his or her left hand and the handle of a cutting tool (140) in his or her right hand, and inject the gripper of the forceps (130) into the first injection port of the single port (120) and inject the cutting portion of the cutting tool (140) into the second injection port of the single port (120).

[0088] Referring to flowchart 400, the processor (314) of the host computer (310) according to one embodiment may determine, in step S410, whether a surgical tool (320) is inserted into the single port (120) of the simulation module based on sensing information received from at least one second sensor (210). First, the processor (314) of the host computer (310) may receive sensing information from at least one second sensor (210) provided inside the housing of the simulation module. The processor (314) may receive sensing information indicating whether a surgical tool (320) is inserted into the single port (120) of the simulation module from the at least one second sensor (210). The processor (314) may determine, based on the sensing information received from the at least one second sensor (210), whether a surgical tool (320) is inserted into the single port (120) of the simulation module.

[0089] According to one embodiment, the processor (314) of the host computer (310) may, in step S420, if it is determined that a surgical tool (320) is inserted into the single port (120), determine the position information and posture information of at least one of the forceps (130) and the cutting tool (140) based on the sensing information received from at least one first sensor (322). If it is determined that a surgical tool (320) is inserted into the single port (120), the processor (314) may receive sensing information from at least one first sensor (322) of the surgical tool (320). The at least one first sensor (322) may include a first-first sensor provided in a handle portion of the forceps (130) and a first-second sensor provided in a handle portion of the cutting tool (140). The first sensor (1-1) can detect position information and posture information of the forceps (130), and the first sensor (1-2) can detect position information and posture information of the cutting tool (140). At least one first sensor (322) may be an electromagnetic (EM) sensor including a 6-axis gyro sensor.

[0090] Meanwhile, based on sensing information received from at least one first sensor (322), a process of aligning the position of the surgical tool (320) to a predetermined fixed coordinate system (e.g., an orthogonal coordinate system) based on position information and posture information of the forceps (130) and the cutting tool (140) may be preceded. The memory of the host computer (310) may store in advance information about the shape of the forceps (130), the shape of the cutting tool (140), the position at which the first-first sensor is provided on the forceps (130), and the position at which the first-second sensor is provided on the cutting tool (140). Based on the information stored in the above-described memory and the information received from at least one first sensor (322), the position information of the surgical tool (320) may be aligned to the fixed coordinate system. For accurate alignment, the processor (314) can receive position information about a surgical tool (320) detected by at least one second sensor (210) from at least one second sensor (210), and can use the received position information about the surgical tool (320) in the alignment process.

[0091] According to one embodiment, the processor (314) of the host computer (310) may, in step S430, generate a virtual surgical environment including virtual forceps and virtual cutting tools corresponding to position information and posture information of at least one of the forceps (130) and the cutting tool (140). The processor (314) may output the virtual surgical environment including the virtual forceps and the virtual cutting tool through the display (150). The virtual surgical environment may include a virtual reality image imitating an organ inside a target object (e.g., a human body). The virtual reality image may be displayed as a first-person view based on the surgical tool (320). For example, the virtual reality image may be displayed as a first-person view based on the endoscopic camera (324) of the surgical tool (320). The virtual reality image will be described in detail with reference to FIGS. 5 and 6.

[0092] FIGS. 5 and 6 are examples of a virtual surgical environment (500) for a single port surgery (e.g., transanal surgery) according to one embodiment of the present disclosure.

[0093] As shown in FIG. 5, a virtual surgical environment (500) output through the display (150) of the host computer (310) may include an image imitating an organ inside the object and an image of a virtual surgical tool (320) corresponding to the surgical tool (320). With respect to the organ inside the object, the internal tissue (510) of the object (e.g., large intestine) corresponding to the single port (120) may appear in the virtual reality image. A virtual surgical tool (520), including a virtual forceps and a virtual cutting tool, may appear in the virtual reality image by a user's manipulation. According to one embodiment, the processor (314) may change the viewpoint of the virtual reality image in real time based on the viewpoint of the endoscopic camera (324). According to one embodiment, the processor (314) may also change the viewpoint of the virtual reality image according to a user's input received through the input device (318).

[0094] If the user selects the first button of the forceps (130), the processor (314) of the host computer (310) can control the virtual forceps to perform a grasping motion in a virtual surgical environment. For example, if the user selects the first button, the processor (314) can control the virtual forceps to grasp or release a virtual object (e.g., a tumor or polyp) in the virtual surgical environment.

[0095] If the user selects the second button of the incision tool (140), the processor (314) can control the virtual incision tool to perform an incision operation in a virtual surgical environment. For example, if the user selects the second button, the processor (314) can control the virtual incision tool to incise a virtual object in a virtual surgical environment.

[0096] According to another embodiment, the single port surgical training device (100) can track the position information and posture information of the surgical tool (320) in real time. For example, the processor (314) of the host computer (310) can track the position information and posture information of the forceps (130) and the cutting tool (140) of the surgical tool (320) in real time based on the sensing information received from at least one first sensor (322) and / or at least one second sensor (210). In the above case, the processor (314) can change the position information and posture information of the virtual forceps and the virtual cutting tool in the virtual surgical environment so as to correspond to the position information and posture information of the forceps (130) and the cutting tool (140).

[0097] In another embodiment, the single-port surgical training device (100) may provide feedback regarding the user's training. For example, if the user fails to grasp the target (220) placed within the simulation module (110) with the forceps (130) for a predetermined time (e.g., 1 minute), the processor (314) may display a warning message (e.g., "Failed to grasp target") via the display (150). For example, if the user fails to incise the target (220) placed within the simulation module (110) with the incision tool (140) for a predetermined time (e.g., 5 minutes), the processor (314) may display a warning message via the display (150).

[0098] As illustrated in FIG. 6, the virtual surgical environment (600) may include a virtual reality image that mimics an internal organ of the subject. For example, the virtual reality image may include a virtual tumor (610) that is a target for resection. The virtual tumor (610) may be a stalk tumor. In embodiments, the virtual surgical environment (600) may further include at least one of a protruded tumor (620 and 640) and a bowl tumor (630).

[0099] In another embodiment, the virtual reality image may be displayed from the perspective of a user wearing a VR device (not shown) (or from the camera view of the VR device). The virtual reality image may be implemented similarly to the perspective of a surgeon performing surgery in an actual operating room. For example, the virtual reality image may include a subject lying on an operating room bed and a monitor displaying internal organs of the subject. The user can experience the perspective of an actual surgeon by viewing the virtual reality image output through the display of the VR device.

[0100] Through various embodiments of the present disclosure, a user can perform single-port surgical training while observing a virtual surgical environment displayed via a display (150). This allows the user to practice surgical procedures while experiencing an experience similar to an actual surgery.

[0101] It is obvious that each step or operation of the method according to the embodiments of the present disclosure can be performed by a computer including one or more processors according to the execution of a computer program stored in a computer-readable recording medium.

[0102] The computer-executable instructions stored in the aforementioned recording medium can be implemented through a computer program programmed to perform each corresponding step, and such a computer program can be stored in a computer-readable recording medium and executed by a processor. The computer-readable recording medium may be a non-transitory readable medium. In this case, the non-transitory readable medium means a medium that semi-permanently stores data and can be read by a device, rather than a medium that stores data for a short period of time, such as a register, a cache, or a memory. Specifically, the programs for performing the various methods described above can be stored and provided in a non-transitory readable medium, such as semiconductor memory devices such as erasable programmable read-only memories (EPROMs), electrically erasable programmable read-only memories (EEPROMs), and flash memory devices, magnetic disks such as internal hard disks and removable disks, optical-magnetic disks, and non-volatile memories including CD-ROMs and DVD-ROM disks.

[0103] The methods according to various examples disclosed in this document may be provided as a computer program product. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read-only memory (CD-ROM)) or online through an application store (e.g., Play Store™). In the case of online distribution, at least a portion of the computer program product may be temporarily stored or temporarily generated in a storage medium, such as the memory of a manufacturer's server, an application store's server, or a relay server.
