Description

Wire-assisted cutting surgical device

[0001] The embodiments of the present disclosure relate to a surgical device for cutting using a wire, and more specifically, to a surgical device for cutting at least a portion of a target tissue inside the body by surrounding it with a wire.

[0002] Modern surgical procedures are evolving toward increasing precision and minimal invasiveness. In particular, surgeries utilizing laparoscopic or endoscopic devices are receiving significant attention due to their advantages, such as shortened patient recovery times, reduced risk of complications, and improved cosmetic outcomes. In these minimally invasive surgeries, the size and maneuverability of surgical instruments, as well as the precise cutting of the target tissue, are critical.

[0003] Conventional tissue cutting devices widely used include electrocauteries, ultrasonic cutters, lasers, and mechanical cutting tools. Electrocauteries use high-frequency currents to cut and coagulate tissue; while they offer the advantage of minimizing bleeding, they have the disadvantage of potentially causing thermal damage to surrounding tissues. Ultrasonic cutters utilize high-frequency vibrations to cut tissue, but precise control can be difficult. Lasers enable highly precise cutting, but they are expensive and can cause thermal damage.

[0004] Furthermore, while mechanical cutting devices using cutting instruments can be used in various surgeries due to their relatively simple structure, they require a high level of skill as the cut surface may become rough or the cut area may widen; it is also important to accurately remove only the target tissue while minimizing damage to surrounding healthy tissue.

[0005] To address these issues, technology is being developed that uses a wire to surround a target tissue inside the body and cuts it through the reciprocating motion of the wire. Wire-based tissue cutting devices offer the advantages of a relatively simple structure, high flexibility, and the ability to perform precise cutting. Accordingly, wire-based cutting is considered a highly useful technology because it can selectively cut only the target tissue, thereby minimizing the impact on surrounding tissues, and can be applied to various types of tissue cutting.

[0006] However, these conventional wire-based surgical devices faced difficulties in positioning the wire to accurately wrap around the target tissue within the body. Consequently, conventional technology suffered from problems such as the need for excessive additional tools to wrap the target tissue with the wire or reduced surgical precision.

[0007] The embodiments of the present disclosure aim to solve various problems, including those mentioned above, by providing an amputation surgical device that can be easily positioned to surround a target tissue within the body. However, these problems are exemplary and do not limit the scope of the present disclosure.

[0008] According to one aspect of the present disclosure, a surgical device for cutting at least a portion of a target tissue by surrounding it with a wire is provided, comprising: a main body having an insertion portion provided at one end and an ejection portion provided at the other end, and having a first channel and a second channel connecting the insertion portion and the ejection portion internally, wherein the ejection portion is inserted into the body and positioned adjacent to the target tissue; a wire positioned to surround at least a portion of one side of the target tissue through the first channel; and a guide portion positioned to surround at least a portion of the other side of the target tissue through the second channel.

[0009] According to the present embodiment, the guide portion includes a ring-shaped member disposed at the end of the guide portion, and the wire can be primarily coupled to the guide portion by being disposed such that at least a portion of the end penetrates the inside of the ring-shaped member.

[0010] According to the present embodiment, the guide member can be secondarily coupled with the wire by rotating in the first coupled state so that the end of the wire is wound around the loop-shaped member.

[0011] According to the present embodiment, as the guide portion moves from the discharge portion toward the insertion portion in the secondary combined state, the wire can surround at least a portion of the target tissue and be inserted into the second channel.

[0012] According to the present embodiment, the guide portion includes a pair of members that are arranged at the ends and extend apart at a certain angle without crossing each other, and the wire can be primarily coupled to the guide portion by being arranged so that at least a portion of the end is interposed between the pair of members.

[0013] According to the present embodiment, the guide member can be secondarily coupled with the wire as the pair of members approach each other in the first coupled state and grip the end of the wire.

[0014] According to the present embodiment, as the guide portion moves from the discharge portion toward the insertion portion in the secondary combined state, the wire can surround at least a portion of the target tissue and be inserted into the second channel.

[0015] According to the present embodiment, the guide portion has a hollow structure, and the end of the guide portion has a J-shape bent backward with curvature, and may be made of an elastic member capable of elastic deformation.

[0016] According to the present embodiment, the elastic member can be deformed into a straight line by an external force and positioned inside the second channel.

[0017] According to the present embodiment, the elastic member is restored to the J-shape by a restoring force when ejected to the outside of the main body through the ejection part, and can be arranged to surround at least a portion of one side of the target tissue from the other side of the target tissue.

[0018] According to the present embodiment, the wire is inserted into the interior of the elastic member at one side of the target tissue and passes through the hollow portion of the guide portion, thereby surrounding at least a part of the target tissue and being inserted into the second channel.

[0019] Other aspects, features, and advantages other than those described above will become clear from the following specific details, claims, and drawings for implementing the invention.

[0020] According to an exemplary embodiment of the present disclosure made as described above, an amputation surgical device can be implemented in which a wire can be easily positioned to surround a target tissue within the body.

[0043] The x-axis, y-axis, and z-axis are not limited to the three axes of an orthogonal coordinate system but can be interpreted in a broader sense that includes them. For example, the x-axis, y-axis, and z-axis may be orthogonal to each other, but they may also refer to different directions that are not orthogonal to each other.

[0044] The advantages and features of the present disclosure and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present disclosure is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure is complete and to fully inform those skilled in the art of the scope of the present disclosure, and the present disclosure is defined only by the scope of the claims.

[0045] The terms used in this disclosure are for describing the embodiments and are not intended to limit this disclosure. In this disclosure, the singular form may include the plural form unless specifically stated otherwise in the text. The terms “comprises” and / or “comprising” used in this disclosure do not exclude the presence or addition of one or more other components in addition to the components mentioned. Throughout the disclosure, the same reference numerals refer to the same components, and “and / or” may include each of the mentioned components and all combinations of one or more. Although terms such as “first,” “second,” etc., are used to describe various components, these components are not limited by these terms.

For example, if a component depicted in a drawing is inverted, a component described as "below" or "beneath" of another component may be placed "above" of that component. Therefore, the exemplary term "below" may encompass both the lower and upper directions. Components may also be oriented in other directions, and accordingly, spatially relative terms may be interpreted according to the orientation.

[0048] Unless otherwise defined, all terms used in this disclosure (including technical and scientific terms) may be used in a meaning commonly understood by those skilled in the art to which this disclosure pertains. Additionally, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.

[0049] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same reference numerals, and redundant descriptions thereof will be omitted.

[0050] FIG. 1 is a perspective view schematically illustrating a part of the main body of an amputation surgical device according to an exemplary embodiment of the present disclosure, and FIG. 2 is a diagram schematically illustrating a part of the main body of an amputation surgical device according to an exemplary embodiment of the present disclosure in which a wire and a guide part are arranged.

[0051] As illustrated in FIGS. 1 and 2, a cutting surgical device (10) according to an exemplary embodiment of the present disclosure may include a main body (100), a wire (200), and a guide part (300).

[0052] The main body (100) may perform the function of providing a path through which at least a portion of the wire (200) and / or guide portion (300) can be inserted into the body. Specifically, one end of the main body (100) may be inserted into the body and positioned adjacent to a target tissue (20, see FIG. 3), and the wire (200) and / or guide portion (300) may be inserted into the body through a channel provided inside the main body (100) and positioned adjacent to the target tissue (20).

[0053] In one embodiment, the main body (100) may be positioned such that at least a portion including a discharge portion (120) is inserted into the body, and at least a portion including an insertion portion (110) is located outside the body. At this time, a surgical tool (e.g., a wire (200), a guide portion (300), etc.) may be inserted into the main body (100) through the insertion portion (110), penetrate the main body (100) through a channel provided inside the main body (100), and be discharged outside the main body (100) through the discharge portion (120), thereby being inserted into the body.

[0054] Here, the target tissue (20) may refer to the tissue to be amputated. There are no restrictions on the type of target tissue (20), and it may include any tissue (e.g., bone, bone marrow, cartilage, ligament, muscle, fascia, nerve, blood vessel, etc.) and / or any organ that constitutes a person or animal that may be subject to amputation surgery.

[0055] Meanwhile, in one embodiment, the target tissue (20) may have a structure in which the upper and / or lower portions of the target tissue (20) are blocked. That is, the target tissue (20) may be placed in an environment where the wire (200) cannot be formed in a ring shape in advance to surround the target tissue (20) through the upper or lower portions of the target tissue (20). In this case, the effect of the present disclosure may be pronounced because the wire (200) must be manipulated to surround the target tissue (20) while the wire (200) is inserted into the body. A detailed description of the process and appearance of the wire (200) being placed to surround the target tissue (20) within the body will be provided later with reference to FIGS. 3 to 7.

[0056] The main body (100) may have an insertion part (110) provided at one end and an emission part (120) provided at the other end. The insertion part (110) and the emission part (120) of the main body (100) may be connected to each other through a channel provided inside the main body (100). More specifically, a plurality of channels connecting the insertion part (110) and the emission part (120) may be provided inside the main body (100). In one embodiment, a first channel (c1) and a second channel (c2) connecting the insertion part (110) and the emission part (120) may be provided inside the main body (100).

[0057] Each of the insertion part (110) and the discharge part (120) may include a plurality of holes. At this time, the plurality of holes included in the insertion part (110) and the plurality of holes included in the discharge part (120) may be connected to each other in a one-to-one manner to form a channel inside the main body (100).

[0058] In one embodiment, the insertion part (110) may include a first insertion hole (110a) and a second insertion hole (110b), and the discharge part (120) may include a first discharge hole (120a) and a second discharge hole (120b). The first insertion hole (110a) and the first discharge hole (120a) may be connected through the main body (100) to form a first channel (c1) inside the main body (100). The second insertion hole (110b) and the second discharge hole (120b) may be connected through the main body (100) to form a second channel (c2) inside the main body (100).

[0059] The first channel (c1) and the second channel (c2) can serve as passages for inserting a wire (200) or a guide part (300) from the outside of the body into the inside. In one embodiment, as shown in FIG. 2, the wire (200) may be positioned to penetrate the main body (100) through the first channel (c1), and the guide part (300) may be positioned to penetrate the main body (100) through the second channel (c2). However, this is not limited thereto, and it is also possible to have the guide part (300) positioned in the first channel (c1) and the wire (200) positioned in the second channel (c2).

[0060] The wire (200) can perform the function of cutting at least a portion of the target tissue (20).

[0061] The wire (200) can be inserted into the body and positioned to surround (or encircle) the target tissue (20), which is the tissue to be cut. The wire (200) can reciprocate while surrounding the target tissue (20) and generate friction and / or heat to perform the function of cutting at least a portion of the target tissue (20). That is, the cutting surgical device (10) of the present disclosure does not require a separate blade or cauterization device, etc., to cut the target tissue (20) as the wire (200) performs the function of a cutting element.

[0062] In one embodiment, the wire (200) may be composed of medical stainless steel 316 (STS316) or stainless steel 316L (STS316L). For example, the wire (200) may contain 16 to 18 wt% chromium (Cr), 11 to 14 wt% nickel (Ni), 2 to 3 wt% molybdenum (Mo), and 0.08 wt% or less carbon (C) (in the case of STS316), or 16 to 18 wt% chromium (Cr), 10 to 14 wt% nickel (Ni), 2 to 3 wt% molybdenum (Mo), and 0.035 wt% or less carbon (C) (in the case of STS316L). However, the thickness and material of the wire (200) are not limited thereto and can be modified into various forms.

[0063] Additionally, in an exemplary embodiment, the wire (200) may be a wire with improved surface strength and wear resistance by being hard-coated with a compound. As a specific example, the compound for coating the wire (200) may be at least one of titanium nitride (TiN), tungsten carbide, titanium-aluminum nitride (TiAlN), tungsten carbide cobalt (Wc-Co) nanopowder, zirconium oxide (ZrO2), metal phosphate, polyurethane, fluorocarbon, silica, hyaluronic acid, and diamond, but is not limited thereto and may include any material that is biocompatible and can improve wear resistance.

[0064] In addition, the types of coatings that may be applied include titanium nitride coating, ceramic coating, silica coating, hyaluronic acid coating, chrome coating, polyurethane coating, fluorocarbon coating, nano coating, and diamond coating, but are not limited thereto.

[0065] In addition, coating methods may include chemical vapor deposition (CVD), physical vapor deposition (PVD), ion beam-assisted deposition (IBAD), thermal or plasma spray and sol-gel methods, spray painting, tumbling, dipping, brush painting, roll printing, bell-shaped rotary atomizing electrostatic coating, etc., but are not limited thereto.

[0066] The guide portion (300) can be combined with the wire (200) inside the body and perform the role of guiding the wire (200) to the outside of the body. Specifically, the guide portion (300) can assist in manipulating the wire (200) inserted into the body to surround the target tissue (20), and further assist in manipulating the wire (200) to pass through another channel of the main body (100) and be expelled outside the body while surrounding the target tissue (20).

[0067] In one embodiment, the guide portion (300) can be inserted into the body through another channel provided in the main body (100) after the wire (200) has been inserted into the body through one channel provided in the main body (100). The guide portion (300) can be coupled with the wire (200) that has been inserted into the body.

[0068] In another embodiment, the guide portion (300) may be inserted into the body through one of the channels provided in the main body (100) before the wire (200). Afterward, the wire (200) may be inserted into the body through another channel provided in the main body (100). The guide portion (300) may be coupled with the subsequently inserted wire (200) inside the body.

[0069] The guide portion (300) can move in a direction from the release portion (120) of the main body (100) toward the insertion portion (110) while combined with the wire (200) inside the body. Accordingly, the wire (200) combined with the guide portion (300) can move together with the guide portion (300). Through this, the wire (200) can be manipulated to surround at least a portion of the target tissue (20) and can be inserted into the channel of the main body (100) through which the guide portion (300) passed.

[0070] The process of arranging a wire (200) to surround a target tissue (20) within the body will be described in detail below with reference to FIGS. 3 to 7. FIGS. 3 to 7 show any target tissue (20) within the body and a portion of an amputation surgical device (10, see FIG. 2) arranged adjacent to it. Additionally, although not illustrated in FIGS. 3 to 7, the upper and / or lower portions of the target tissue (20) may be blocked by other components of the body.

[0071] FIG. 3 is a schematic diagram illustrating a wire of a cutting surgical device according to an exemplary embodiment of the present disclosure positioned on one side of a target tissue.

[0072] As illustrated in FIG. 3, the wire (200) can be positioned to surround at least a portion of one side of the target tissue (20) through the first channel (c1).

[0073] The wire (200) can be positioned to penetrate the main body (100) through the first channel (c1) as it is inserted into the main body (100) through the first insertion hole (110a) of the insertion part (110) and discharged through the first channel (c1) to the first discharge hole (120a). The wire (200) discharged outside the main body (100) through the first discharge hole (120a) can be positioned to move away from the discharge part (120) and surround at least a portion of one side of the target tissue (20).

[0074] As such, the wire (200) of the present disclosure approaches the side of the target tissue (20), and has the effect of being able to surround the target tissue (20) even in a structure where the upper and / or lower parts of the target tissue (20) are blocked.

[0075] After placing the wire (200) on one side of the target tissue (20), the guide portion (300) can be placed on the other side of the target tissue (20). Specifically, the guide portion (300) can be placed to surround at least a portion of the other side of the target tissue (20) through the second channel (c2). The guide portion (300) can be coupled with the wire (200) in an area adjacent to the target tissue (20).

[0076] At this time, the method of joining the wire (200) and the guide part (300) may vary depending on the shape of the guide part (300). Hereinafter, the joining process of the wire (200) and the guide part (300) according to three embodiments of the guide part (300) according to the present disclosure will be described. Specifically, a first embodiment of the guide part (300) will be described with reference to FIGS. 4a and 4b, a second embodiment of the guide part (300) will be described with reference to FIGS. 5a and 5b, and a third embodiment of the guide part (300) will be described with reference to FIGS. 6a and 6b.

[0077] FIG. 4a is a schematic diagram illustrating the first combination of a wire and a guide part of an amputation surgical device according to the first embodiment of the present disclosure, and FIG. 4b is a schematic diagram illustrating the second combination of a wire and a guide part of an amputation surgical device according to the first embodiment of the present disclosure.

[0078] As illustrated in FIG. 4a, the guide portion (300) included in the cutting surgical device (10, see FIG. 2) according to the first embodiment may include a ring-shaped member disposed at the end of the guide portion (300). Here, the ring shape may be a circle, an ellipse, a polygon, etc., but is not limited thereto and may be any shape with a hollow center.

[0079] The guide portion (300) can be inserted into the body through a channel different from the channel through which the wire (200) passes among the plurality of channels provided in the main body (100). The guide portion (300) inserted into the body can be placed on the other side of the target tissue (20) (the side opposite to the side where the wire (200) is placed).

[0080] In one embodiment, the wire (200) may be positioned to surround at least a portion of one side of the target tissue through the first channel (c1), and the guide portion (300) may be positioned to surround at least a portion of the other side of the target tissue (20) through the second channel (c2).

[0081] In this way, with the wire (200) and the guide part (300) positioned in an area adjacent to the target tissue (20), the wire (200) and the guide part (300) can be combined with each other in two stages.

[0082] Referring to FIG. 4a, the wire (200) can be primarily coupled with the guide portion (300) by being positioned so that at least a portion of its end penetrates the inner side of the ring-shaped member of the guide portion (300). Specifically, the ring-shaped member of the guide portion (300) according to the present embodiment can be configured so that at least a portion of the end of the wire (200) penetrates the inner side.

[0083] Referring to FIG. 4b, the guide member (300) can be secondarily coupled with the wire (200) by rotating while in a state of primary coupling with the wire (200) so that at least a portion of the end of the wire (200) is wound (or entangled) around the ring-shaped member of the guide member (300). That is, the ring-shaped member of the guide member (300) according to the present embodiment is capable of rotational motion, and can be configured so that the wire (200) placed inside the ring-shaped member can be wound around the ring-shaped member according to the rotational motion. Through this, the guide member (300) and the wire (200) can be coupled more strongly.

[0084] Meanwhile, in this embodiment, the rotational movement of the guide part (300) can be performed by an external force provided to the guide part (300). For example, the rotational movement of the guide part (300) can be achieved by a user rotating the opposite end of the part of the guide part (300) where the ring-shaped member is located, but is not limited thereto. As another example, the rotational movement of the guide part (300) can be achieved through a rotational movement device connected to the opposite end of the part of the guide part (300) where the ring-shaped member is located. Here, the rotational movement device may be an electronic device coupled to the end of the guide part (300) to provide rotational force to the guide part (300).

[0085] Through this secondary connection, the wire (200) and the guide part (300) are more strongly connected, which has the effect of reducing the risk of separation during subsequent operation, that is, the risk of the guide part (300) losing the wire (200).

[0086] In the state where the wire (200) and the guide part (300) are secondarily combined, as the guide part (300) moves from the discharge part (120) of the main body (100) toward the insertion part (110) (hereinafter, guide part removal direction), the wire (200) surrounds at least a portion of the target tissue (20). Additionally, as the guide part (300) continues to move in the guide part removal direction, the wire (200) can be inserted into the second channel (c2) of the main body (100) along the guide part (300), and furthermore, can be discharged outside the main body (100) through the insertion part (110) of the main body (100) while connected to the guide part (300).

[0087] Meanwhile, in an optional embodiment, the following features may be included so that the primary coupling of the wire (200) and the guide part (300) can be easily performed.

[0088] In one embodiment, the ring-shaped member of the guide portion (300) is composed of an elastic member capable of elastic deformation, and the diameter of the ring-shaped member may be larger than the inner diameter of the channel in which the guide portion (300) is placed. Accordingly, when the ring-shaped member of the guide portion (300) is placed inside the channel of the main body (100) (e.g., the second channel (c2)), it may be placed in a shape that is compressed (or pressed) by an external force on the inner wall of the channel of the main body (100). When the ring-shaped member of the guide portion (300) is discharged to the outside of the main body (100) through the discharge portion (120) of the main body (100), it may be restored to a shape having its original diameter by a restoring force. Likewise, when the ring-shaped member of the guide part (300) is re-entered into the main body (100) while combined with the wire (200), it can be inserted in a deformed (or pressed) shape due to an external force on the inner wall of the channel of the main body (100).

[0089] According to the present embodiment, when the ring-shaped member of the guide part (300) is released from the body to the outside of the main body (100), the diameter of the ring shape can be formed relatively larger. Accordingly, the primary coupling process of the guide part (300) and the wire (200), that is, the arrangement of at least a portion of the end of the wire (200) to penetrate the inside of the ring-shaped member of the guide part (300) within the body, is made easier.

[0090] In one embodiment, the ring-shaped member of the guide portion (300) may be composed of a magnetic member. In this case, when the ring-shaped member of the guide portion (300) is placed adjacent to the end of the wire (200), it can be coupled to the end of the wire (200) through magnetism. Accordingly, there is an effect of making it easier to first combine the guide portion (300) and the wire (200).

[0091] FIG. 5a is a schematic diagram illustrating the first combination of a wire and a guide part of an amputation surgical device according to a second embodiment of the present disclosure, and FIG. 5b is a schematic diagram illustrating the second combination of a wire and a guide part of an amputation surgical device according to a second embodiment of the present disclosure.

[0092] As illustrated in FIG. 5a, the guide portion (300) included in the amputation surgery device (10, see FIG. 2) according to the second embodiment may include a pair of members that are positioned at the end of the guide portion (300) and extend apart at a certain angle without crossing each other. Here, the pair of members may refer to members forming a clamp shape (or a V-shape). Additionally, the pair of members can grasp an object (e.g., a wire) placed between the pair of members as the clamp shape opens and closes. That is, the pair of members can grasp or fix an object (e.g., a wire) placed between the pair of members through the process of the clamp shapes coming close to each other and making contact. Specifically, the pair of members having a clamp shape of the guide portion (300) according to the present embodiment may be configured so that at least a portion of the end of the wire (200) can be placed between the pair of members while they are spread apart.

[0093] In one embodiment, the wire (200) may be positioned to surround at least a portion of one side of the target tissue through the first channel (c1), and the guide portion (300) may be positioned to surround at least a portion of the other side of the target tissue (20) through the second channel (c2).

[0094] In this way, with the wire (200) and the guide part (300) positioned in an area adjacent to the target tissue (20), the wire (200) and the guide part (300) can be combined with each other in two stages.

[0095] Referring to FIG. 5a, the wire (200) can be primarily coupled with the guide portion (300) by being positioned so that at least a portion of its end is interposed between a pair of members of the guide portion (300).

[0096] Referring to FIG. 5b, the guide portion (300) can be secondarily coupled with the wire (200) as a pair of members approach each other and grasp the end of the wire (200) while in a state of primary coupling with the wire (200). That is, the guide portion (300) according to the present embodiment can grasp an object (e.g., wire) placed between the pair of members, which have a clamp shape, by opening and closing each other. The pair of members can grasp or fix (grasp) the object (e.g., wire) placed between the pair of members through the process of the clamp shapes approaching and contacting each other.

[0097] Meanwhile, although detailed illustration of the relevant components is omitted in FIG. 5a and FIG. 5b, a pair of members of the guide section (300) according to the present embodiment can be operated to move closer to or further apart from each other according to user operation. This operation can be implemented through an operating section (not shown) located at the opposite end from the part where the pair of members of the guide section (300) are positioned. The operating section includes a trigger-shaped handle that detects user operation and an actuator that converts the movement of the trigger into power, and these components can be mechanically coupled to operate organically with each other.

[0098] The above trigger is designed to be movable in a first direction (moving away from the user) and a second direction (pulling towards the user) according to the user's operation, and mechanical force can be transmitted to an actuator through the movement of the trigger. The actuator controls a pair of members of the guide section (300) by converting or amplifying the force transmitted from the trigger, and through this process, the movement of the pair of members of the guide section can be controlled to move closer to or further away from each other. Specifically, when the trigger moves in the first direction, the actuator can bring the pair of members of the guide section closer to or in contact with each other, and when the trigger moves in the second direction, it can cause the pair of members of the guide section to move further away from each other.

[0099] In the process of transmitting the input transmitted from the trigger to the guide section (300), the actuator transmits power through components such as mechanical links, shafts, or cables, or controls the movement of the guide section (300). In this process, the actuator and the guide section (300) may be designed to include not only mechanical connections but also elastic elements or damping devices, so that stable fixation and release of the work object can be achieved. The organic combination of the trigger, actuator, and guide part (300) can precisely transmit user input and stably perform the necessary operations on the work target, thereby greatly improving the efficiency and accuracy of the wire gripping operation. As the guide part (300) moves from the discharge part (120) of the main body (100) toward the insertion part (110) (hereinafter, guide part removal direction) while the wire (200) and the guide part (300) are in the secondary combined state, the wire (200) surrounds at least a part of the target tissue (20). Additionally, as the guide portion (300) continues to move in the direction of removal of the guide portion, the wire (200) can be inserted into the second channel (c2) of the main body (100) along the guide portion (300), and furthermore, can be discharged outside the main body (100) through the insertion portion (110) of the main body (100) while connected to the guide portion (300).

[0100] In an optional embodiment, a pair of members of the guide portion (300) may be composed of magnetic members. In this case, when the pair of members of the guide portion (300) are positioned adjacent to the end of the wire (200), they may be coupled to the end of the wire (200) through magnetism. Accordingly, there is an effect of making it easier to first combine the guide portion (300) and the wire (200).

[0101] FIG. 6a is a schematic diagram illustrating the first combination of a wire and a guide part of an amputation surgical device according to the third embodiment of the present disclosure, and FIG. 6b is a schematic diagram illustrating the second combination of a wire and a guide part of an amputation surgical device according to the third embodiment of the present disclosure.

[0102] As illustrated in FIG. 6a, the guide portion (300) included in the cutting surgical device (10, see FIG. 2) according to the third embodiment may have a hollow structure. For example, the guide portion (300) may be in the form of a hollow tube or a cylinder, but is not limited thereto. Additionally, the inner diameter of the hollow of the guide portion (300) may be larger than the outer diameter of the wire (200). Accordingly, the wire (200) may be inserted into the interior of the guide portion (300) or pass through (or move) the interior of the guide portion (300).

[0103] Additionally, the end of the guide portion (300) may have a J-shape that is curved backward and may be made of an elastic member capable of elastic deformation. Accordingly, when the elastic member of the guide portion (300) is placed inside the channel (e.g., second channel (c2)) of the main body (100), it may be deformed into a straight line by an external force on the inner wall of the channel of the main body (100). Furthermore, when the elastic member of the guide portion (300) is discharged to the outside of the main body (100) through the discharge portion (120) of the main body (100), it may be restored to its original J-shape by a restoring force. During the process of being discharged to the outside of the main body (100) and restored to a J-shape as described above, the elastic member of the guide portion (300) may be positioned to surround at least a portion of one side of the target tissue (20) from the other side of the target tissue (20).

[0104] Referring to FIG. 6a, the guide portion (300) is inserted into the main body (100) through the second insertion hole (110b) of the insertion portion (110) of the main body (100), and can be ejected outside the main body (100) through the second channel (c2) and the second ejection hole (120b) of the ejection portion (120). During the ejection process of the guide portion (300), the elastic member at the end of the guide portion (300) is restored to a J-shape (bent backward) and can be positioned to surround at least a portion of one side of the target tissue (20) from the other side of the target tissue (20) adjacent to the ejection portion (120).

[0105] Meanwhile, the wire (200) can be inserted into the main body (100) through the first insertion hole (110a) of the insertion part (110) of the main body (100), and can be ejected outside the main body (100) through the second ejection hole (120a) of the ejection part (120) after passing through the first channel (c1). The wire (200) ejected outside the main body (100) can be placed on one side of the target tissue (20).

[0106] Referring to FIG. 6b, the wire (200) can move from the insertion part (110) of the main body (100) toward the discharge part (120). Accordingly, the wire (200) can be inserted into the elastic member of the guide part (300) through the opening at the end of the elastic member of the guide part (300) on one side of the target tissue (20). As the wire (200) continues to move from the insertion part (110) of the main body (100) toward the discharge part (120) and passes through the hollow part of the guide part (300), it can be inserted into the second channel (c2) while surrounding at least a part of the target tissue (20). Furthermore, the wire (200) can be moved to the opposite end of the part where the elastic member of the guide part (300) is located and discharged outside the guide part (300), thereby being discharged outside the body.

[0107] Next, with the wire (200) and the guide part (300) positioned as in FIG. 6b, the guide part (300) can be pulled away from the insertion part (110) of the main body (100) to remove the guide part (300) from the body and from inside the main body (100).

[0108] FIG. 7 is a schematic diagram illustrating a wire of a cutting surgical device according to an exemplary embodiment of the present disclosure arranged to surround a target tissue. Specifically, FIG. 7 is a diagram showing the final state in which the wire (200) is arranged to surround the target tissue (20) after undergoing the processes described in FIG. 4a to 6b above.

[0109] As illustrated in FIG. 7, the wire (200) can be positioned to be inserted into the first insertion hole (110a), surround the target tissue (20), and discharge through the second insertion hole (110b). Specifically, the wire (200) can be inserted into the main body (100) through the first insertion hole (110a) of the insertion part (110) of the main body (100), discharged outside the main body (100) through the first discharge hole (120a) of the discharge part (120) by passing through the first channel (c1), surround the target tissue (20) from one side to the other, be inserted back into the main body (100) through the second discharge hole (120b), and discharged outside the main body (100) through the second insertion hole (120a) by passing through the second channel (c2). At this time, the discharge portion (120) of the main body (100) may be inserted into the body, and the insertion portion (110) may be located outside the body. Accordingly, the wire (200) may be positioned such that both ends are located outside the body, and at least a portion of the wire (200) is inserted into the body to surround the target tissue (20).

[0110] In this manner, with the wire (200) positioned, the tension of the wire (200) is maintained by pulling both ends of the wire (200), and the target tissue (20) can be cut by reciprocating the two ends of the wire (200) in different directions (a direction away from or towards the insertion part (110) of the main body (100).

[0111] FIG. 8 is a schematic diagram illustrating the operation of a cutting surgical device according to an exemplary embodiment of the present disclosure in conjunction with an endoscope device.

[0112] The amputation surgical device (10) according to an exemplary embodiment of the present disclosure may be used in conjunction with an endoscope device (30). However, it is not limited thereto, and the amputation surgical device (10) may be used independently without being linked with an endoscope device, or may be used in conjunction with a device other than an endoscope device.

[0113] In one embodiment, the endoscope device (30) may include a plurality of openings, and the amputation surgical device (10) may be inserted into the body through any one of the plurality of openings of the endoscope device (30). That is, the amputation surgical device (10) may be inserted into the interior of the endoscope device (30) through an insertion part (not shown) provided at one end of the endoscope device, penetrate the endoscope device (30) through a channel provided inside the endoscope device (30), and be discharged outside the endoscope device (30) through a discharge part provided at the other end of the endoscope device (30).

[0114] For a specific example, referring to FIG. 8, the discharge portion of the endoscope device (30) may include a first opening (30a), a second opening (30b), and a third opening (30c). The first opening (30a), the second opening (30b), and the third opening (30c) of the endoscope device (30) may each be connected to different channels within the endoscope device (30). Additionally, a device for performing a specific function may be placed in each of the different channels, or other surgical devices may be inserted. For example, the first opening (30a) may be connected to a channel into which a cutting surgical device (10) is inserted. The second opening (30b) and the third opening (30c) may each be connected to a channel equipped with a lighting device or a photographic device. However, it is not limited to this, and it goes without saying that the number of openings included in the endoscope device (30), the type and function of the device placed in the channel connected to each opening, etc., can be varied in many ways.

[0115] FIGS. 9 and 10 are schematic drawings illustrating a wire of a cutting surgical device according to an exemplary embodiment of the present disclosure arranged to surround a target tissue.

[0116] In FIGS. 1 to 8 described above, the main body (100) of the cutting surgical device (10) of the present disclosure is shown in a straight cylindrical shape, but the shape of the main body (100) is not limited thereto and can be varied in many ways.

[0117] As a specific example, as illustrated in FIG. 9, the shape of the main body (100) may be a rectangular prism shape. As another specific example, as illustrated in FIG. 10, the shape of the main body (100) may be a rectangular prism bent at a specific angle. FIG. 10 illustrates an example where one end of the main body (100) is bent at 90 degrees, but the angle of bending can be varied in many ways. When the end of the main body (100) has a bent shape like this, it has the effect of easily accessing and positioning the discharge part (120) even in a target tissue (20) that is difficult to access with a straight main body (100).

[0118] In addition, the location and number of insertion holes and discharge holes provided in the main body (100) can be varied. As shown in FIG. 9, the discharge section (120) may be provided on a side adjacent to the end of the main body (100), rather than at the end of the main body (100). Specifically, the first discharge hole (120a) and the second discharge hole (120b) may be provided on a side adjacent to the end of the main body (100). In this case, even for target tissue (20) located deep from the surgical incision or where there is little space accessible from the side, it is easy to position the discharge section (120) of the main body (100), namely the first discharge hole (120a) and the second discharge hole (120b), adjacent to the target tissue (20).

[0119] Meanwhile, the surgical device (10) for cutting surgery having the shape of the main body (100) shown in FIGS. 9 and 10 also has the same process and principle of the wire (200) described with reference to FIGS. 3 to 7 being positioned to surround the target tissue (20) inside the body, so a redundant description will be omitted.

[0120] Furthermore, although the present disclosure has primarily described devices for amputation surgery, it is not limited thereto. For example, a method for manufacturing such an amputation surgery device is also considered to fall within the scope of the present disclosure.

[0121] Although the present disclosure has been described with reference to the embodiments illustrated in the drawings, this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present disclosure should be determined by the technical spirit of the appended claims.
