Abstract
Description
Technical Field
[0001] The present invention relates to a bipolar energy device, that is, when the clamp parts formed by the upper jaw and the lower jaw in the form of a clamp for holding the blood vessel and treating with electric energy are connected to each other, a short circuit phenomenon can be avoided by forming a space between the upper jaw and the lower jaw, thereby ensuring the stability of the structure and the safety for the human body. Background Art
[0002] Laparoscopic surgery is a surgery that is performed by making a small hole in the side of the abdomen and injecting air into it to expand the abdomen for easier observation, and then observing the inside of the abdominal cavity. Laparotomy is a general term for surgery that is performed by cutting open the abdomen.
[0003] For such laparoscopic and laparotomy surgeries, it is extremely important to accurately grasp and cut blood vessels. In this regard, surgical tools that use electricity or ultrasound to cut surgical sites are currently being developed and commercialized in a diversified manner. However, problems with surgical tools that use the above-mentioned electricity or ultrasound for cutting also present themselves in various ways.
[0004] For example, "BIPOLAR" is a surgical tool for cutting using electricity. It has an upper jaw and a lower jaw joined in a clamp-like shape to hold the blood vessel, uses electrical energy to generate heat to facilitate cutting of tissue, and uses blades (blades) provided on both the upper jaw and the lower jaw to perform treatment.
[0005] However, in the above-mentioned conventional bipolar device, when the upper jaw and the lower jaw on which different electrodes are respectively mounted are joined, a short circuit may easily occur due to the absence of a gap, thereby causing a disadvantage of being accompanied by structural and physical dangers.
[0006] Furthermore, when the wheel rim rotatably coupled to the outer cover rotates 360 degrees, the upper jaw and the lower jaw also rotate 360 degrees, and accordingly, the pipe connected together also rotates. In this case, there is a problem that the cable of the power supply unit provided in the outer cover also rotates together.
[0007] Therefore, there is an increasing demand for electric energy cutting surgical tools that can solve the above-mentioned problems.

[0078] The pipe portion 110 is a pipe that serves as a reference axis for the clamp portion 120 described later to perform a clamping action (opening and closing action) and a guide axis for providing a path for the blade portion 130 described later, and may include an outer pipe 111 and an inner pipe 112 .
[0079] The outer pipe 111 may be cylindrical.
[0080] Preferably, the inner pipe 112 can penetrate the outer pipe 111 along the length direction and move.
[0081] The forceps portion 120 may be in the form of a clamp for grasping a portion to be operated on. According to the present invention, the forceps portion 120 may be formed by an upper jaw 120a and a lower jaw 120b having an opening 121 formed on the inner side along the length direction and having different electrodes (not shown) respectively. The forceps portion 120 may be hingedly connected to one end of the pipe portion 110 so that the opening 121 may be opened or closed.
[0082] The upper jaw 120 a may be coupled to one end of the inner pipe 112 , and the lower jaw 120 b may be coupled to one end of the outer pipe 111 .
[0083] The hinge structure between the pipe part 110 and the clamp part 120 may be fastened by a bearing member (not shown), a connecting rod member (not shown), etc., and various known hinge structures may be adopted.
[0084] On the other hand, refer to Figure 3 Part (b) of Figure 4 According to a preferred embodiment of the present invention, a protrusion 122 may be formed on one of the facing surfaces of at least one of the upper jaw 120a and the lower jaw 120b of the pliers portion 120, so as to form a gap between the upper jaw 120a and the lower jaw 120b when the pliers portion 120 performs a closing action.
[0085] In this case, the protrusion 122 may be formed of a ceramic material and protruded in a circular shape with a predetermined interval around the circumference of a surface facing the upper jaw 120 a and the lower jaw 120 b .
[0086] And, refer to Fig.11 The structure of the protrusion 122 can be inserted into the hole 123a of the plate 123 described later in the form of a blade 122' or a ceramic plate 122".
[0087] A stainless steel plate 123 may be mounted on opposing surfaces of the upper jaw 120 a and the lower jaw 120 b of the jaw portion 120 .
[0088] Preferably, the plate 123 is formed with a hole 123a through which the protrusion 122 provided on the upper jaw 120a and the lower jaw 120b passes, the guide groove 123b is formed along the length direction of the upper jaw 120a and the lower jaw 120b, and a concave-convex portion 123c for anti-slip is formed in the area other than the hole 123a and the guide groove 123b.
[0089] More preferably, the clamp part 120 may further include an insulating cover 124 interposed between the upper jaw 120 a and the lower jaw 120 b and combined with the plate 123 .
[0090] The insulating cover 124 may cover the entire inner and outer portions of the upper jaw 120 a and the lower jaw 120 b except for a space formed between the upper jaw 120 a and the lower jaw 120 b and a region corresponding to the blade portion 130 .
[0091] Preferably, the insulating cover 124 is made of ceramic or flame-retardant plastic to have insulation, corrosion resistance and heat resistance.
[0092] The blade portion 130 can move along the length direction in the internal pipe 112 to extend through one end of the pipe portion 110 and expose to the opening 121 of the upper jaw 120a and the lower jaw 120b. According to the present invention, it can be composed of a metal wire 131 and a blade 132.
[0093] The metal wire 131 may be combined with the handle portion 140 and move along a length direction in the inner tube 112 .
[0094] The blade 132 may be connected to the metal wire 131 and exposed to the openings 121 of the upper jaw 120 a and the lower jaw 120 b , and may move along a path guided by the guide groove 123 b of the plate 123 as the metal wire 131 moves.
[0095] The handle portion 140 may form an outer cover 140a that accommodates the internal pipe 112 exposed to the other side of the pipe portion 110 and allows the user to hold it, and is used to control the movement of the forceps portion 120 and the blade portion 130, and to supply power to the electrodes of the upper jaw 120a and the lower jaw 120b, and may include a forceps driving unit 141, a blade driving unit 142, a power supply unit 143 and an anti-detachment unit 144.
[0096] like Figure 7 As shown, the pliers driving unit 141 is arranged on the outer cover 140a, so that the internal pipe 112 moves horizontally along the length direction, so that the pliers part 120 performs the opening and closing action of the opening 121 through the hinge structure with the pipe part 110, and may include a first guide member 141a, a flange 141b, a first rod 141c, a first connecting rod 141d and a first spring 141e.
[0097] The first guide 141 a has a large outer diameter and is fastened to an outer surface of the inner pipe 112 received in the outer cover 140 a without interfering therewith.
[0098] The flanges 141b are located on both sides of the first guide member 141a, and are pressed and integrated with the outer surface of the inner pipe 112 to form protrusions (not shown) that support the first guide member 141a along the periphery.
[0099] Preferably, the first rod 141c is disposed outside the outer cover 140a so that the user can hold it, but the present invention is not limited thereto and the design may be changed in various ways within the technical scope of the present invention.
[0100] The first link 141d is interposed between the first guide 141a and the first rod 141c. When the first rod 141c is held by a user and subjected to pressure, the first guide 141a is tilted to be closer to the rotating portion 150 and the inner pipe 112 is horizontally moved.
[0101] The first spring 141e is disposed between the inner side surface of the outer cover 140a located on the rotating portion 150 side and the first guide member 141a. When the first guide member 141a moves in a manner close to the rotating portion 150 side, tension is generated by elasticity. When the pressure on the first rod 141c is eliminated, the generated tension is utilized to reset the first guide member 141a, the first rod 141c and the first connecting rod 141d.
[0102] like Figure 8 As shown, the blade driving unit 142 is disposed on the blade portion 130 for making the blade portion 130 move horizontally in a horizontal direction, and may include a second guide 142a, a second rod 142c, a second connecting rod 142d and a second spring 142e.
[0103] The second guide 142a has a larger outer diameter and is fastened to the outer surface of the inner pipe 112 received in the outer cover 140a without interference, and is spaced apart from the first guide 141a in the opposite direction of the rotating part 150 side.
[0104] Furthermore, the second guide 142 a is connected to the blade portion 130 in the inner pipe 112 , and preferably, is connected to the metal wire 131 .
[0105] Preferably, the second rod 142c is disposed outside the outer cover 140a so that the user can hold it, but its position and shape are not limited thereto and the design can be changed in various ways within the technical scope of the present invention.
[0106] The second link 142d is interposed between the second guide 142a and the second rod 142c. When the second rod 142c is held by a user and pressed, the second guide 142a is tilted closer to the first guide 141a and the blade portion 130 is horizontally moved.
[0107] The second spring 142e is disposed between the first guide member 141a and the second guide member 142a. When the second guide member 142a moves toward the first guide member 141a, tension is generated by elasticity. When the pressure on the second rod 142c is eliminated, the generated tension is utilized to reset the second guide member 142a, the second rod 142c, and the second connecting rod 142d.
[0108] In this case, according to the present invention, a portion of the first rod 141c and the second rod 142c may contact each other, and a groove (not shown) or a protrusion (not shown) may be formed at the contacting portion to engage with each other, thereby locking or unlocking the second rod 142c depending on whether the first rod 141c is pressurized.
[0109] The power supply unit 143 generates heat by applying electricity to the electrodes of the upper jaw 120 a and the lower jaw 120 b , and a person skilled in the art may use a variety of known power supply components.
[0110] Reference Fig. 9 The anti-detachment unit 144 is disposed in the outer cover 140a to support the other end of the inner pipe 112 in a manner to prevent the inner pipe 112 from moving, without interfering with the rotation and horizontal movement of the inner pipe 112, and may include a jack 144a.
[0111] Preferably, the socket 144a is spaced apart from the other end of the internal pipe 112 in the outer cover 140a, and a straight groove (not shown) is formed along the length direction on the same line as the horizontal movement direction of the internal pipe 112.
[0112] According to the present invention, preferably, the handle portion 140 as described above supplies power to the electrodes of the upper jaw 120a and the lower jaw 120b while being controlled to close the forceps portion 120, and after the power supply is completed, the blade portion 130 is operated.
[0113] like Figure 6 As shown, the rotating part 150 is rotatably (rotatably) disposed outside the outer cover 140a of the handle part 140 where the other end of the external pipe 111 is located, fastening the external pipe 111 and allowing the external pipe 111 to rotate.
[0114] The rotating portion 150 may include a rotating wheel 151 , a locking portion 152 , a rotating pin 153 and an extending slot 154 .
[0115] The rotating wheel 151 is rotatably interposed between the other end of the outer pipe 111 and the outside of the outer cover 140a to support the outer pipe 111 and form an internal space for accommodating a portion of the inner pipe 112 exposed from the other end of the outer pipe 111.
[0116] Preferably, the locking portion 152 is formed toward the internal pipe 112 accommodated in the internal space of the rotating wheel 151 .
[0117] Preferably, one end of the rotating pin 153 passes through a portion of the internal pipe 112 accommodated in the internal space of the rotating wheel 151, and the other end is arranged to be locked in the locking portion 152, so as to fasten the rotating wheel 151 and the internal pipe 112, and has a rotation radius of 360 degrees in the internal space along the rotation direction of the rotating wheel 151.
[0118] The extension groove 154 further extends along the length direction of the inner pipe 112 through the portion through which the rotation pin 153 passes.
[0119] In this case, the internal pipe 112 can horizontally move along the extension groove 145 without interference in the length direction by the extension distance of the extension groove 154, and can rotate without interference in the state of being fastened to the rotating wheel 151 by the rotating pin 153.
[0120] That is, according to the present invention, when the outer pipe 111 coupled to the lower jaw 120 b rotates, the rotating portion 150 as described above can simultaneously rotate the inner pipe 112 .
[0121] Reference Fig.10 The sealing portion 160 is disposed on the pipe portion 110 to prevent foreign matter from flowing into the gap between the external pipe 111 and the internal pipe 112 and into the interior of the internal pipe 112 , and may include a sealing plug 161 and a sealing ring 162 .
[0122] The sealing plug 161 is filled in the outer pipe 111 and extends to fill the inner pipe 112 , thereby preventing foreign matter from flowing into the inner pipe 112 for the first time, and allowing the blade portion 130 to pass through through a preset first resistance.
[0123] Preferably, the sealing plug 161 is made of polytetrafluoroethylene material having excellent chemical resistance and heat resistance, and may also be made of stainless steel, but is not limited thereto.

[0125] In this case, preferably, the first resistance is a resistance that can enable the blade portion 130 to move horizontally alone and will not be coupled with the blade portion 130 under the rotational movement of the internal pipe 112 .
[0126] The second resistance is a resistance that can link the inner pipe 112 with the rotation of the outer pipe 111 and force the inner pipe 112 to move in the length direction when the forceps driving unit 141 is in motion.
[0127] Therefore, the present invention has the following effect, namely, when the upper jaw 120a and the lower jaw 120b having different electrodes are in a closed state, a short circuit phenomenon can be avoided by forming a protrusion 122 on the opposite side of at least one of the upper jaw 120a and the lower jaw 120b in a manner that forms a gap between the upper jaw 120a and the lower jaw 120b. Thus, the structural stability of the device 100 can be ensured, and the safety for the human body can be ensured at the same time.
[0128] Furthermore, the present invention can have the following effect, that is, the rotating part 150 rotatably arranged on the outside of the outer cover 140a is connected to the pipe part 110 through a keyway structure, so that the rotational movement of the external pipe 111 and the internal pipe 112 can be more easily linked at the same time, and the internal pipe 112 can be selectively horizontally moved (linearly moved) in the length direction.
[0129] Furthermore, the first guide 141 a , the second guide 142 a , and the flange 141 b may realize the forceps driving unit 141 and the blade driving unit 142 with simpler structures, so that the forceps part 120 and the blade part 130 may be operated more effectively.
[0130] At the same time, the anti-detachment unit 144 that supports the linear position of the internal tube 112 can be fixed by guiding the horizontal movement of the internal tube 112 and utilizing elasticity to prevent detachment and unnecessary movement in the movement direction of the internal tube 112, thereby further improving structural reliability and surgical accuracy.
[0131] Furthermore, the sealing portion 160 provided in the pipe portion 110 can prevent the device 100 from malfunctioning, and the protrusion 122, plate 123 and insulating cover 124 of the clamp portion 120 having insulating, corrosion-resistant and heat-resistant properties can further improve the structural stability of the device 100 and its safety for the human body.
