Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a multifunctional surgical electrosurgical unit. Background Technology

[0002] Surgical electrosurgical units are widely used in the medical field and are important surgical instruments. The working principle of an electrosurgical unit is to use high-voltage current to cut and stop bleeding in body tissues; its output power is very high, reaching over 200W. During surgery, the electrosurgical unit produces smoke when cutting and electrocoagulating muscle and fat tissue. This smoke can easily obstruct the surgeon's vision and affect the progress of the operation. Secondly, the electrosurgical tip is prone to accumulating eschar, which is an insulating layer and severely affects the cutting and cauterization of the electrosurgical unit. Therefore, it is necessary to temporarily stop the procedure, attach an electrosurgical cleaning pad to a sterile drape, and rub the eschar away on the cleaning pad. In addition, during electrosurgical resection, if there is exudate from the incision, it is necessary to use a suction device to remove the fluid. Smoke, eschar, and the procedure of absorbing exudate affect the speed and safety of the surgery.

[0003] Existing technology, such as Chinese Patent Publication No. CN205729503U, discloses a smoking electrosurgical unit, including an electrosurgical body, a smoking tube, and a housing disposed outside the smoking tube; the electrosurgical body has a surgical part and a connecting part, the surgical part extends out of the smoking tube, the connecting part is connected to the mounting part of the smoking tube, and a spiral expansion plug structure is formed between the outer wall of the smoking tube and the inner wall of the housing, the spiral expansion plug structure includes a spiral expansion plug member, when the smoking tube and the spiral expansion plug member rotate relative to each other, the wall thickness formed by the cooperation of the smoking tube and the spiral expansion plug member changes locally, causing the degree of expansion of the smoking tube relative to the housing to change.

[0004] Chinese Patent CN206995329U discloses an electrosurgical unit with convenient smoking function. It includes an electrosurgical body, an electrosurgical blade at each end of the body, and a smoking tube. The smoking tube is connected to a negative pressure bottle. The electrosurgical blade is hollow, with an outwardly protruding arc-shaped portion at its front end, on which a first smoking hole is located. A protrusion at the top of the blade provides a second smoking hole. A third smoking hole is located at the end of the electrosurgical body facing the electrosurgical blade. The first, second, and third smoking holes are all sealed to the smoking tube. The smoking tube is connected to the negative pressure bottle via a three-way connector, with the remaining port on the three-way connector connected to a surgical negative pressure device.

[0005] Chinese patent CN 219331891 U discloses a surgical electrosurgical unit with the function of absorbing eschar and smoke, including an electrosurgical head, an electrosurgical handle, and electrical wiring; a suction device is connected to the side of the electrosurgical handle near the electrosurgical head, the suction device includes a suction hood, a fan, a storage container, and a hose, the suction hood is connected to the head end of the electrosurgical handle, one end of the storage container is connected to the suction hood, the other end of the storage container is connected to the hose, and the hose is connected to the fan; the electrosurgical head is also provided with an eschar removal device, the eschar removal device includes a telescopic sleeve and a drive mechanism;

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] Example 1:

[0036] A multi-functional surgical electrosurgical unit, such as Figure 1 As shown, it includes a processor, a housing 1, an electric blade 2, an adsorption assembly, and a scab removal assembly, wherein:

[0037] The outer casing 1 includes the casing and the end cap 22. The upper and lower parts of the casing are provided with sliding grooves 11, which allow the pin shaft 10 to extend and slide. The front part of the casing is provided with an opening, which allows the head of the power blade 2 to extend out. The end cap 22 is provided with a connecting pipe port and a power wire port, which allow the connecting pipe to extend out and the power wire to extend out.

[0038] The electric blade 2 has its tail end connected to the electric knife control device via a wire. The electric knife control device is then connected to the processor. The electric blade 2 also has two control buttons, namely the electrocoagulation button and the electric cutting button, which are both located on the outer casing 1 and electrically connected to the electric knife control device of the electric blade 2. Both the electric blade 2 and the electric knife control device are conventional technologies for controlling the electric blade 2, so they are not elaborated on here.

[0039] The scab removal assembly includes an inner shell 8, a scab removal head 3, a scab removal blade 5, and a sliding mechanism, wherein:

[0040] Remove scabs, 3, such as Figure 3 As shown, it is connected to the inner shell 8 to form a complete receiving cavity. The electric blade 2 is set in this receiving cavity and can slide in the receiving cavity. The front part of the descaling head 3 is provided with an opening 4, which allows the head of the electric blade 2 to extend out. A descaling blade 5 matching the position of the head of the electric blade 2 is provided on the opening 4. In this embodiment, the descaling blade 5 is arranged around the opening 4 and has a rectangular frame structure that matches the shape of the electric blade 2. In this way, when the electric blade 2 moves, the scabbed surface of it can be scraped off by the descaling blade 5, which can easily remove the scabbed surface.

[0041] The sliding mechanism, mainly used to drive the electric blade 2 to slide within the accommodating cavity, includes a pull member 9, a pin 10, and a sliding plate 24, wherein:

[0042] There are two pull parts 9, which are respectively attached to the two sides of the electric blade 2 to fix the electric blade 2 and are fixed by the pin 10. In addition, there are sliding grooves 23 on the inner walls of the descaling head 3 and the inner shell 8 for the pull parts 9 to slide. In this way, the pull parts 9 move along the sliding grooves 23 when they move.

[0043] The pin 10 passes vertically through the two pull members 9 and is fixed to the pull members 9. Moreover, the two ends of the pin 10 pass through the grooves 11 on the inner shell 8 and the outer shell 1, respectively.

[0044] Sliding pieces 24 are installed at both ends of the pin 10, and their width is greater than the width of the groove 11;

[0045] The overall working principle of the sliding mechanism is as follows: by controlling the sliding plate 24, the user can control the pin 10 to slide in the slide groove 11, thereby controlling the electric blade 2 to slide in the accommodating cavity, and finally realize the movement of the head of the electric blade 2 at the opening 4, so as to realize the removal of scabs by the scab removal blade 5 on the head of the electric blade 2.

[0046] The adsorption assembly, mainly used to attract the smoke generated during the electrosurgical procedure, includes a suction tube 7 and a suction device, wherein:

[0047] There are two straws 7, which are respectively set on both sides of the inner shell 8. The two straws 7 are connected to each other through a connecting tube and are connected to the suction device. There are gaps between the scab removal head 3 and the outer shell 1. These gaps form the suction port 6. The head of the straw 7 is connected to this suction port 6. The suction device is a conventional product of the prior art, so it is not described in detail here.

[0048] Working principle of the adsorption component: After the suction device is activated, it generates suction force, which can suck away the smoke generated when the electrosurgical unit is working;

[0049] The processor, which mainly controls the operation of the suction device and the electric blade 2, is a conventional technology in the prior art, so it will not be discussed in detail here.

[0050] In this way, the entire electrosurgical unit can absorb the smoke generated during operation, and the electrosurgical blade 2 can also be retracted into the outer casing 1 to remove scabs.

[0051] Example 2:

[0052] The difference from Embodiment 1 is that Embodiment 2 also includes a protective assembly for the electric blade 2, two limit switches, and the suction device has two settings, specifically:

[0053] The protective assembly includes a closing element 12 and a return spring 13, wherein the closing element 12, as... Figure 4 As shown, there are two, located on the upper and lower sides of the electric blade 2 respectively. Each closing part 12 includes a closing part 14, a first connecting part 15, a rotating part 16, a second connecting part 17, and a baffle part 18 connected in sequence. The rotation is achieved by a connecting shaft rotatably connecting to the inner wall of the descaling head 3. A groove is provided on the second connecting part 17, and a corresponding groove is also provided on the descaling head 3. Thus, one end of the return spring 13 abuts against the second connecting part 17, and the other end abuts against the descaling head 3. The baffle part 18 is arranged perpendicular to the second connecting part 17, and the closing part 14 is arranged parallel to the baffle part 18. The first connecting part 15... 5 The included angle formed by the connection between the rotating part 16 and the second connecting part 17 is an obtuse angle, and an inclined push block 19 is also provided on the pulling part 9, that is, one pulling part 9 corresponds to one closing part 12. When the pulling part 9 moves to a certain position, the inclined push block 19 will push the baffle part 18, thereby driving the closing part 12 to rotate as a whole. When the pulling part 9 moves to the closed position, the inclined push block 19 will push the baffle part 18 to the closed position. At this time, the closing parts 14 of the two closing parts 12 abut against each other, and the electric blade 2 is located inside the cavity enclosed by the two closing parts 12, thus protecting the electric blade 2.

[0054] Two limit switches, namely the first limit switch 20 and the second limit switch 21, are electrically connected to the processor. The first limit switch 20 is installed on the inner wall of the scab removal head 3, and the second limit switch 21 is installed on the inner wall of the inner shell 8. That is, when the user controls the sliding plate 24 to move to the open position, the pulling member 9 also moves to the open position. At this time, the electric blade 2 extends out of the outer shell 1 and is in working condition. At the same time, the pulling member 9 will trigger the first limit switch 20, and then the processor will adjust the suction to the smoking mode, that is, the mode with lower suction, so that the electric blade can be used for one... Smoking while working; when the user controls the sliding plate 24 to move to the closed position, the pull member 9 also moves to the closed position. At this time, the electric blade 2 retracts into the housing 1 and is in a resting state. At the same time, the pull member 9 will trigger the second limit switch 21, and then the processor will adjust the suction level to the liquid suction level, that is, the level with greater suction, so that the electric blade can perform liquid suction operation when resting. And because the two closing members 12 are also closed at this time, the head of the electric blade 2 can be protected from contacting the suctioned liquid during liquid suction, which can effectively protect the electric blade 2.

[0055] The overall working principle of this embodiment is as follows:

[0056] After the electric blade 2 extends, the electric coagulation and electric cutting operations are realized by the electric coagulation button and the electric cutting button. At the same time, the suction device is in the smoke-smoking mode to suck out the smoke. At this time, the first limit switch 20 is pressed and the second limit switch 21 is released. If neither the electric coagulation button nor the electric cutting button is pressed, the suction device stops sucking.

[0057] During the retraction of the electric blade 2, the scab removal component removes the scab. At this time, both the first limit switch 20 and the second limit switch 21 pop up, the suction stops working, and pressing the electrocoagulation and electrocution buttons has no effect.

[0058] With the electric blade 2 retracted, the suction device is in liquid aspiration mode, drawing out liquid. At this time, the second limit switch 21 is pressed, and the first limit switch 20 is released. Pressing the electrocoagulation and electrosurgical cutting buttons will have no effect.

[0059] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

[0060] For those skilled in the art, various changes and modifications will undoubtedly be apparent after reading the above description. Therefore, the appended claims should be considered as covering all changes and modifications that encompass the true intent and scope of this utility model. Any and all equivalent scope and content within the scope of the claims should be considered as still falling within the intent and scope of this utility model.
