Description

{A Filter Embedded Type of a Surgical Device for Discharging a Gas}

The present invention relates to a surgical device with a built-in filter-type gas suction structure, and more particularly, to a surgical device with a built-in filter-type gas suction structure capable of suctioning and removing gas generated during a surgical procedure.

During the surgical procedure, a part of the human body may be incised, and after the incision, blood vessels may be coagulated with ultrasonic energy or electrical energy for hemostasis or similar purposes. During this procedure, smoke may be generated, and gases containing various odor components generated from inside the human body may leak to the outside through the incision site. Smoke may obscure the view during the surgical procedure, and odor components may have a negative effect on the operator. Therefore, it is necessary to ensure that gas components containing smoke are discharged through a designated discharge path. International Publication No. WO 2007/070570 discloses a waste collection and processing system for collecting and processing waste materials such as body fluids generated during medical procedures in hospitals, for example. In addition, Patent Publication No. 10-2016-0138852 discloses a harmful gas filter device for a surgical trocar set. Gas containing smoke generated during the surgical procedure must be discharged to the outside as soon as it is generated, and at the same time, it must have a simple structure. However, the prior art does not disclose a surgical device for removing a gas containing smoke having such a structure.

The present invention is intended to solve the problems of prior art and has the following objectives.

Prior art 1: International Publication No. WO 2007/070570 (Striker Corporation, published on June 21, 2007) Medical/surgical smoke evacuation device including internal sensor and smoke filter Prior art 2: Patent publication number 10-2016-0138852 (Lee Byeong-gap, published on December 6, 2016) Harmful gas filter device for surgical trocar set

The purpose of the present invention is to provide a surgical device having a gas suction structure with a built-in filter that allows gases containing various types of odor components generated during an incision or coagulation process to be discharged to the outside through a designated path.

According to a preferred embodiment of the present invention, a surgical tool with a built-in filter-type gas suction structure comprises: an induction body that introduces gas generated during a coagulation or incision process while guiding a contact tip for coagulation or incision; a handle case that is connected to the induction body and has a filter disposed therein; and a suction means that is connected to the handle case and discharges the introduced gas through a filter module.

According to another suitable embodiment of the present invention, the suction means is a gas suction pump.

According to another suitable embodiment of the present invention, the suction means is operated in synchronization with the surgical tip or is operated continuously.

The surgical device with a built-in gas suction structure according to the present invention causes gas containing smoke generated during the process of coagulating a cut human body part by, for example, ultrasonic energy or high-frequency energy to be discharged along a set path at the same time as it is generated. This prevents the field of vision from being obscured by smoke during the surgical process, and prevents gas containing odor from leaking to the outside and affecting the operator. The surgical device according to the present invention can be applied to various types of surgical devices that require gas discharge during the surgical process, including surgical devices for incision and coagulation having a pen shape, and the present invention is not limited thereby.

Below, the present invention is described in detail with reference to embodiments shown in the attached drawings, but the embodiments are for a clear understanding of the present invention and the present invention is not limited thereto. In the description below, components having the same drawing symbols in different drawings have similar functions and therefore will not be described repeatedly unless necessary for the understanding of the invention, and well-known components will be briefly described or omitted, but they should not be understood as being excluded from the embodiments of the present invention.

FIG. 1 illustrates an embodiment of a surgical device having a filter-built-in gas suction structure according to the present invention.

Referring to FIG. 1, a surgical device with a built-in filter gas suction structure includes an induction body (12) that introduces gas generated during a coagulation or incision process while guiding a contact tip (13) for coagulation or incision; a handle case (11) that is connected to the induction body (12) and has a filter module arranged therein; and a suction means that is connected to the handle case (11) and discharges the introduced gas via the filter module (14).

The surgical instrument may have the function of cutting or coagulating a part of the body by being inserted into the human body during a surgical procedure such as laparoscopic surgery, for example. For example, the surgical instrument may have the function of coagulating a blood vessel at the incision site by generating heat with high-frequency electric energy or ultrasonic energy to stop bleeding at the incision site while cutting tissues inside the human body during an abdominal surgical procedure. The coagulation means may be a contact tip (13) having a cutter shape capable of cutting and coagulating by applying electric energy or ultrasonic energy, such as a Bovie tip, for example. The contact tip (13) extends along the inside of the guide body (12) and protrudes out of the guide body (12) so as to contact a blood vessel or a surgical site of the human body during the surgical procedure to cut or coagulate. The guide body (12) may have a hollow cylinder shape and may have the function of introducing a gas containing an odor component generated during the incision or coagulation process into the inside of the surgical tool while guiding the contact tip (13). Specifically, the induction body (12) may be composed of an inlet body (122) made of a transparent material with a hollow cylinder shape; and an extension block (121) connecting the inlet body (122) and the handle case (11). The inner diameter of the inlet body (122) may be sufficiently larger than the diameter of the contact tip (13) that linearly extends along the inside of the inlet body (122) and protrudes to the outside. Due to this difference in diameter, an inlet through which gas can be introduced may be formed at the end of the inlet body (122). The gas introduced through the inlet may flow along the inside of the inlet body (122), flow along the handle case (11), and be introduced to a suction means via the filter module (14) and the discharge hose (15). The inlet body (122) may be coupled to an extension block (121) that is extended to have an overall hollow cylindrical shape and an increasing diameter while having a hollow cylindrical shape, so as to be adjustable in length. For example, the coupling portion of the inlet body (122) may be formed by screw coupling or sliding coupling with the extension block (121) to form a locking portion. When the screw coupling length or the sliding coupling length is adjusted to a predetermined length, the rotation or sliding movement may be limited by the locking tab. By adjusting the length in this way, the level of gas introduced may be adjusted depending on the surgical site or surgical method. The length adjustment of the inlet body (122) may be performed in various ways, and the present invention is not limited thereby.

A hollow cylindrical handle case (11) may be extended from an extension block (121), and a conductive member may be extended along the inside of the handle case (11) to be connected to a contact tip (13). An accommodation space may be formed inside the handle case (11), and elements or parts necessary for operation may be arranged in the accommodation space while allowing gas introduced through an inlet of the accommodation space to flow. A filter module (14) may be arranged inside the handle case (11), and a discharge hose (15) may be connected to the rear of the handle case (11), and the discharge hose (15) may have various structures that allow gas to flow along the inside. The discharge hose (15) may be made of various structures that are elastic and allow gas to flow, and the present invention is not limited thereby. A cable for power supply or data transmission/reception may be arranged along the inside of the discharge hose (15) or along the outer circumferential surface of the discharge hose (15), and the discharge hose (15) may be connected to a connector (16), and a power connection means (CT) for power supply to the connector (16) may be connected to the cable. In addition, a fastening tab (17) may be formed at one end of the connector (16), and the fastening tab (17) may be connected to a suction pump. By the operation of the suction pump, gas flowing along the inside of the handle case (11) may be introduced into the inside of the suction pump via the discharge hose (15) and the connector (16), filtered, and discharged to the outside. An embodiment of a suction pump having such a function will be described again below.

Various operating means for operating the surgical instrument may be arranged in the handle case (11). For example, an incision switch (18a) for proceeding with the incision process or a coagulation switch (18b) for proceeding with the coagulation process may be arranged. By operating the coagulation switch (18b), ultrasonic waves, high frequency or similar coagulation energy may be applied to the incision or cutting site. Various types of switches for proceeding with the surgical process may be arranged in the operating body, and the present invention is not limited thereby.

FIG. 2 illustrates an embodiment of a gas pump that is connected to a surgical device according to the present invention and sucks in and discharges gas.

Referring to Fig. 2, the suction means is a suction pump (20). The suction pump (20) can be placed inside a housing (21) having an overall hexahedral box shape, and an inlet port (22) can be formed on one part of the housing (21). The fastening tab (17) described above can be coupled to the inlet port (22) so that gas can be induced into the inside of the housing (21). The suction pump (20) can have the function of a control device for the operation of a surgical tool, and specifically, it can have a structure in which the suction pump (20) is built into the inside of the control device. A screen (23) that displays the operating status of the surgical instrument or the operating status of the suction pump (20) can be placed on the front surface of the housing (21), and a detection sensor (24) can be placed on the side surface of the housing (21). The detection sensor (24) can detect the operating status of the surgical instrument, and for example, can detect whether the coagulation switch (18b) has been operated. The detection line (25) for detecting the operation means of the coagulation switch (18b) or other operation means may be connected between the operation means and the detection sensor (24). A pump module may be arranged inside the housing (21), and the pump module may be a gas suction pump similar to a compressor or vacuum pump capable of suctioning gas. The pump module may be, for example, a piston pump capable of suctioning gas, a gas diaphragm pump, a rotary vane pump, a linear pump, or a reciprocating piston pump, but is not limited thereto. According to one embodiment of the present invention, the pump module may be operated in synchronization with the operation means, and may be synchronized based on information detected by the detection sensor (24). For example, the pump module may be operated in synchronization with the coagulation process. Specifically, when the operation of the coagulation switch is detected by the detection sensor (24), the operation of the pump module may be automatically initiated. For example, when the operation of the coagulation switch is detected by the detection sensor (24), the pump module may be automatically operated after 2 to 5 seconds have elapsed after the initiation of detection. The detection sensor (24) can detect, for example, the generation of a microcurrent generated by the operation of the coagulation switch. When such a microcurrent is detected by the detection sensor (24), the operation of the pump module can be initiated, and thereby gas including smoke or odor generated during the coagulation process can be introduced into the interior of the surgical device and guided to the housing. The interruption of the operation of the coagulation switch can be detected by the detection sensor (24), and the pump module can continue to operate for 3 to 5 seconds after the interruption is detected. Alternatively, the pump module can be forcibly operated according to the operation of the discharge switch. The gas introduced into the pump module can be discharged through the discharge port (27) arranged on the rear surface of the housing (21). The discharge port (27) can be formed in various structures, such as a plurality of slit structures or a plurality of discharge hole structures, and the present invention is not limited thereby. A cable (W) for supplying power for the operation of the suction pump (20) can be connected to the rear surface of the housing (21) or another appropriate location. Various types of filter modules may be placed in the discharge port (27) depending on the need or the operating environment. For example, a filter module such as a replaceable carbon filter or an activated carbon filter may be placed inside the discharge port (27). Various types of filter modules may be placed depending on the surgical environment, and the present invention is not limited thereby.

Figure 3 illustrates another embodiment of a surgical device according to the present invention.

Referring to FIG. 3, the surgical instrument includes a handle case (11) (11a, 11b) having an accommodating space formed therein by forming an induction path (112); a filter module (14) disposed inside the handle case (11a, 11b) and into which gas containing foreign substances flowing through the induction path (112) is introduced; and a gas flow means (32a, 32b) disposed in front or behind the filter module (14). The surgical instrument may have a function of generating heat with high-frequency electric energy or ultrasonic energy to coagulate blood vessels at the incision site while cutting tissue inside the human body during abdominal surgery to stop hemostasis at the incision site. The coagulation means may be, for example, a contact tip (13) such as a bobbin (Bovie Tip) that enables cutting and coagulation by application of electric energy or ultrasonic energy. The handle case (11a, 11b) may have a hollow cylinder shape or a pen shape, and may have an open front end structure. The handle cases (11a, 11b) may have various structures that can be held and handled in the hand during the surgical procedure, and may have a structure in which first and second handle cases (11a, 11b) having the same or similar structures are combined. An accommodation space may be formed inside the handle cases (11a, 11b), and an induction path (112) may be formed in at least one handle case (11a, 11b). The induction path (112) may have a structure that extends from an inlet (111) formed at the front of the handle cases (11a, 11b) to the front of the filter module (14). The front portions of the handle cases (11a, 11b) may have an open shape, and an extension block (121) may be combined at the front portions of the handle cases (11a, 11b), and an inlet body (122) may be combined to the extension block (121) so that its length can be adjusted. The contact tip (13) can be fixed by being joined to the inside of the inlet body (122) or the handle case (11a, 11b) by various types of fixing means (123), and contact tips (13) having different structures can be joined to the fixing means (123). Electrical energy or ultrasonic energy can be transmitted to the contact tip (13), and blood vessels or similar human body parts can be cut or coagulated by the contact tip (13). In addition, during such cutting or coagulation, odor components, smoke, or similar foreign substances can be generated. In this way, odor components or smoke generated inside the human body during the surgical procedure contain harmful substances and can have a bad effect on the operator or assistant. Therefore, it is necessary to discharge the gas containing the smoke or odor to the outside in a way that does not affect the surgical procedure. It is advantageous that such gas is immediately guided to the outside after being generated and guided along a closed guidance path. To this end, the gas can be guided to the outside through a separately installed suction means and processed. However, if a separate suction means is installed, the surgical device becomes complicated and the surgical space may also become narrow, which has a disadvantage. In order to solve this disadvantage, according to one embodiment of the present invention, gas generated at a surgical site of a human body during a surgical process including smoke or odor may be introduced through an inlet (111) formed at the front of a handle case (11a, 11b) or an inlet body (122) and may be moved through an induction path (112) formed along the interior of the handle case (11a, 11b) and guided to a filter module (14). As the gas flows along the filter module (14), smoke components, odor components, or similar foreign substances may be removed. In addition, the gas passing through the filter module (14) may be guided to a suction pump via a discharge hose as described above. The filter module (14) may include, for example, an activated carbon filter (ACF); a pre-filter made of polypropylene or polyethylene; an ultra-low penetration air (ULPA) filter; Or it can be composed of a plurality of filters such as DNA filters. The plurality of filters can be made in a layered structure, and the plurality of filters can be overlapped to form a filter module, which can be placed inside the handle case (11a, 11b). A pair of fixing tabs can be formed in a structure extending in a circular shape along the inner circumference of the inside of the handle case (11a, 11b), and the filter module (14) can be stably fixed to the inside of the handle case (11a, 11b) by the fixing tabs, thereby filtering all flowing gases. Optionally, a gas flow means (32a, 32b) can be installed at the front or rear of the filter module (14). The gas flow means (32a, 32b) can include a driving motor or a rotating fan rotated by the driving motor. The gas flow means (32a, 32b) can be combined with the filter module (14) to form an independent module structure, and the filter module (14) can have a replaceable structure. The front end of the handle case (11a, 11b) can be a hollow cylinder shape that extends to a constant diameter after the diameter is reduced, and the rear end of the handle case (11a, 11b) can be formed to form a sealed structure in a cone shape so that a discharge hose can be connected. The middle part of the handle case (11a, 11b) can be a hollow cylinder shape with a constant diameter, and a switch module (19) composed of a cut switch (18a) and a coagulation switch (18b) can be coupled to the middle part. A filter area can be formed at the front or the rear of the switch module, and a filter module (14) and a gas flow means (32a, 32b) can be arranged inside the filter area. The gas flow means (32a, 32b) may or may not be coupled to the filter module (14). When the gas flow means (32a, 32b) are combined, the power supply cable (33) is discharged to the rear of the handle case (11a, 11b) and can be placed inside or outside the discharge hose as described above.

A control board (31) for controlling the operation of the medical device may be placed inside the handle case (11a, 11b), and the control board (31) may be electrically connected to the switch module and wiring (33). Various means for operating the surgical device may be placed inside the handle case (11a, 11b), and the surgical device may be connected to an external control device in various ways, and the present invention is not limited thereby.

Figure 4 illustrates an embodiment of the operation process of a surgical device according to the present invention.

Referring to FIG. 4, the operation process of the surgical device includes a step (P41) in which cutting or coagulation is initiated; a step (P42) in which the operation of the cutting or coagulation process is detected; a step (P43) in which the pump is operated according to the synchronized setting according to the operation detection; a step (P44) in which the operation status of the surgical device or the operation status such as whether gas is introduced is detected; and a step (P45) in which the pump suction operation is executed. In the surgical process, for example, the coagulation process may be initiated when the coagulation switch is operated (P41). As described above, the initiation of coagulation may be detected by detection of a microcurrent (P42), and accordingly, the pump may be initiated into operation according to a preset method (P43). The synchronized operation may be performed according to the preset method, and may be performed for, for example, 1 to 10 seconds. Thereafter, the surgical process or the operation of the surgical device is detected (P44), and accordingly, the pump may be operated in synchronized operation or forcibly operated according to the preset method (P45). The pump can be operated in various ways to suction the gas generated during the surgical procedure and is not limited to the presented embodiments.

Although the present invention has been described in detail above with reference to the presented embodiments, those skilled in the art will be able to make various modifications and variations without departing from the technical spirit of the present invention by referring to the presented embodiments. The present invention is not limited by such modifications and variations, but is only limited by the claims attached below.
