Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a large-aperture portable surgical electric hook with smoke suction function. Background Technology

[0002] In laparoscopic, thoracic, and endoscopic thyroid surgeries, electrocautery hooks are widely used as surgical instruments with tissue separation, cutting, and hemostasis functions. However, during surgery, the large amount of smoke generated by the electrocautery hook can severely affect the surgical field of vision, and the high concentration of smoke can easily condense on the laparoscope lens, blurring the laparoscopic video and increasing surgical risks and prolonging the operation time.

[0003] During surgery, assistants often need to intermittently open the vent of the laparoscopic cannula to expel smoke or use a suction device to remove the smoke. On the other hand, assistants also need to frequently remove the lens and wipe it with iodine-soaked gauze. This series of operations seriously affects the progress of the surgery, and the collapse of the air cavity caused by hastily releasing air and smoke can also affect the surgical procedure and even lead to danger.

[0004] Currently, although electric hooks with smoking functions are available on the market, such devices cannot control the smoking function or require a valve to stop the surgical operation to control its opening and closing. Therefore, they are inconvenient to operate, affect the surgical process, and waste human resources.

[0005] Furthermore, the smoke extraction channels of currently available electric hooks with smoking functions are relatively narrow, resulting in low smoke extraction efficiency and potential blockage. Therefore, existing technology cannot meet the need for convenient smoke extraction from electric hooks used in laparoscopic surgery. A more convenient, safe, and efficient smoke extraction device is urgently needed in laparoscopic surgery. Utility Model Content

[0006] The purpose of this invention is to address the deficiencies in the existing technology by proposing a large-aperture portable surgical electric hook with smoke suction function.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A portable surgical electric hook with a large aperture and smoke suction function includes a housing, a tube inserted into the left side of the housing, a circuit assembly installed inside the housing, an electric core passing through the tube, the right side of the electric core being inserted into the circuit assembly, and the left side of the electric core having an L-shaped tip.

[0009] The housing is connected to a flexible tube, and the end of the flexible tube away from the housing is connected to the negative pressure suction system of the operating room. The housing is equipped with a switch assembly, which is used to control the partial opening and closing of the flexible tube.

[0010] The switch assembly includes a V-shaped rocker, a spring, and a slider. The V-shaped rocker has a V-shaped structure. The flexible tube passes through the inside of the V-shaped rocker. The bottom center of the V-shaped rocker is connected and fixed to the pivot, and the right side is connected and fixed to the spring base. The V-shaped rocker is hinged to the inside of the housing through the pivot, so that the V-shaped rocker can rotate with the pivot as the fulcrum.

[0011] The upper end of the spring is fixed to the inner wall of the housing, and the lower end of the spring is connected to the spring base. The right side of the V-shaped rocker can move downward under the action of the spring and squeeze the hose to achieve partial closure of the hose.

[0012] The housing has a strip-shaped hole near the top for inserting a slider. The slider can slide within the strip-shaped hole and is located above the V-shaped rocker and the hose. The slider can be manually repositioned to control the V-shaped rocker to rotate within the housing around the pivot.

[0013] Furthermore, the V-shaped rocker consists of two V-shaped rods with closed ends, and the middle position of its bottom is fixedly connected to the pivot.

[0014] Furthermore, the tube body is made of insulating material, and the inside of the tube body has a hollow structure. The battery cell is located in the center of the tube body, and the tube body squeezes and fixes the battery cell that passes through it.

[0015] Furthermore, the tube body and the housing are movably connected, and the battery cell and the circuit assembly are movably connected.

[0016] Furthermore, the V-shaped rocker is made of hard metal.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model allows the surgeon to control the smoke exhaust with their fingers and has a hand-controlled state, a normally open state, and a normally closed state. During use, the surgeon can switch between different modes as needed, making it more flexible, convenient, and quick. It has strong controllability and is more suitable for complex situations during surgery.

[0019] 3. The tube body in this utility model has a hollow structure, with a larger channel diameter, higher smoke exhaust efficiency, and is less prone to clogging.

[0020] 4. This utility model has a simple structure and is a disposable medical consumable with low manufacturing cost, which helps to save medical expenses and reduce the burden on patients.

[0021] In summary, this utility model features a manual control mode, a normally open mode, and a normally closed mode, allowing users to switch between different modes as needed. The larger diameter of the tube provides higher smoke extraction efficiency, making it more flexible, convenient, and controllable, and better suited for complex surgical situations. Furthermore, its simple structure and low cost help save medical expenses and reduce the burden on patients. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0032] Reference Figure 1-7A portable surgical electric hook with a large aperture and smoke suction function includes a housing 1, which is easy for surgeons to hold; a tube 2 is inserted into the left side of the housing 1, and a circuit assembly 3 is installed inside the housing 1; a battery 4 is inserted inside the tube 2; the right side of the battery 4 is inserted into the circuit assembly 3, and the left side of the battery 4 has a specially shaped battery tip 41; the battery tip 41 can be made into different structural shapes according to surgical needs. Figure 1 and 2 As shown in the figure, the tip 41 of the battery cell in this embodiment has an L-shaped structure.

[0033] A flexible tube 5 is connected inside the housing 1; the end of the flexible tube 5 away from the housing 1 can be connected to the negative pressure suction system of the operating room. A switch assembly 6 is provided inside the housing 1.

[0034] like Figure 3 As shown, the switch assembly 6 includes a V-shaped rocker 61, a spring 62, and a slider 63. The V-shaped rocker 61 consists of two V-shaped rods with closed ends. A pivot 611 is fixed at the middle of its bottom, and a spring base 612 is fixed on its right side. The upper end of the spring 62 is fixed to the inner wall of the housing 1, and the lower end of the spring 62 is connected to the spring base 612. The V-shaped rocker 61 is hinged to the inside of the housing 1 through the pivot 611, allowing the V-shaped rocker 61 to rotate with the pivot 611 as the fulcrum. The flexible hose 5 passes through the inside of the V-shaped rocker 61. The right side of the V-shaped rocker 61 can move downward under the action of the spring 62, squeezing the flexible hose 5 and achieving partial closure of the flexible hose 5.

[0035] The housing 1 has a strip-shaped hole 11 near the top, through which a slider 63 is inserted. The slider 63 can slide within the strip-shaped hole 11 and is located above the V-shaped rocker 61 and the hose 5. The slider 63 can be manually changed to control the V-shaped rocker 61 to rotate within the housing 1 with the pivot 611 as the fulcrum.

[0036] When slider 63 is located in the middle of the slot 11, the V-shaped rocker 61 is not affected by slider 63, that is, slider 63 does not exert a downward force on the V-shaped rocker 61; when slider 63 is located at the rightmost side of the slot 11, the right side of the V-shaped rocker 61 is pressed downward by slider 63 and spring 62, thus partially closing the hose 5; when slider 63 is located at the leftmost side of the slot 11, the left side of the V-shaped rocker 61 is pressed down by slider 63, causing the right side of the V-shaped rocker 61 to move upward with pivot 611 as the fulcrum, thus opening the hose 5.

[0037] The working principle and usage process of this utility model are as follows:

[0038] First, connect the end of the flexible tube 5 furthest from the housing 1 to the operating room negative pressure suction system, and then connect the wire 32 to the operating room energy platform. Human tissue is then cut within the surgical area via the tip 41 of the electrode, generating smoke during the cutting process.

[0039] like Figure 5 As shown, the manual control state of the switch assembly 6 is as follows: When intermittent suction of smoke from the surgical area is required, the slider 63 is moved to the middle of the strip hole 11. At this time, the V-shaped rocker 61 is no longer affected by the slider 63. The surgeon can press the left side of the V-shaped rocker 61 with their hand, and the right side of the V-shaped rocker 61 will move upward, compressing the spring 62. At this time, the hose 5 opens, and the smoke from the surgical area will enter the operating room negative pressure suction system from the surgical area through the tube body 2, the shell 1, and the hose 5 under the action of negative pressure suction. When the pressure on the left side of the V-shaped rocker 61 is released, the elasticity of the spring 62 controls the right side of the V-shaped rocker 61 to squeeze the hose 5 downward, at which time the hose 5 is partially closed.

[0040] like Figure 6 As shown, the normally open state of the switch assembly 6: When continuous suction of smoke from the surgical area is required, the slider 63 can be moved to the left side of the strip hole 11. At this time, the left side of the V-shaped rocker 61 will move downward and be fixed under the pressure of the slider 63, and the right side of the V-shaped rocker 61 will move upward. The hose 5 will remain open, and the smoke from the surgical area will enter the operating room negative pressure suction system from the surgical area through the tube 2, the shell 1, and the hose 5 in sequence under the action of negative pressure suction.

[0041] like Figure 7 As shown, the normally closed state of the switch assembly 6 is as follows: when it is not necessary to draw out the smoke in the surgical area, the slider 63 can be moved to the right side of the strip hole 11. At this time, the right side of the V-shaped rocker 61 will move downward and be fixed, and the hose 5 will remain closed to prevent the left side of the V-shaped rocker 61 from being accidentally touched by the surgeon.

[0042] like Figure 4 As shown, in this embodiment, the tube body 2 is made of insulating material, and the interior of the tube body 2 has a hollow structure. The battery cell 4 is located at the center of the tube body 2. The tube body 2 presses and fixes the battery cell 4 inserted inside it.

[0043] The V-shaped rocker arm 61 is made of hard metal. In this embodiment, it is made of stainless steel.

[0044] In this embodiment, the tube 2 and the shell 1 are movably connected, and the battery cell 4 and the circuit assembly 3 are movably connected.
