Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of LEEP knife smoke exhaust, in particular to a smoke exhaust device for cervical LEEP knife conization. BACKGROUND

[0002] Cervical LEEP (Loop Electrosurgical Excision Procedure) knife conization, as a common minimally invasive surgery for treating cervical lesions, is widely used in clinical practice. This surgery uses high-frequency electric waves to achieve tissue cutting, while also having hemostatic function. However, a large amount of surgical smoke is generated during the operation, which contains cell fragments, viruses (such as HPV), and harmful chemical substances, etc., causing many problems for the operation.

[0003] The existing technology has the following deficiencies and shortcomings: The existing smoke exhaust measures often fail to efficiently and timely exhaust the surgical smoke generated during the operation from the operating room. The surgical smoke diffuses in the room, causing a sharp decline in air quality in the operating room, making the entire surgical environment dirty, which not only affects the work experience of medical staff, but also may have potential impact on the normal operation of other precision equipment in the operating room. The diffused smoke can block the view of medical staff, making the surgical field become blurred. This increases the difficulty of medical staff in accurately identifying the boundary of the lesion tissue and the surrounding normal tissue, thereby affecting the precision of the operation, which may lead to prolonged operation time, even mis-cutting normal tissue, etc., increasing the risk of operation.

[0004] The viruses (such as HPV) and other pathogens contained in the surgical smoke are infectious. Since the existing smoke exhaust technology cannot effectively prevent the spread of smoke, medical staff are inevitably exposed to the environment containing pathogens, and long-term inhalation of these smoke will greatly increase the risk of virus infection, posing a serious threat to the health of medical staff. Harmful chemical substances and cell fragments, etc. may cause respiratory inflammation, allergic reactions, and other diseases. Over time, it may also lead to the occurrence of chronic respiratory diseases, such as chronic bronchitis, asthma, etc., seriously affecting the occupational health and quality of life of medical staff. Therefore, a smoke exhaust device for cervical LEEP knife conization is proposed. SUMMARY

[0005] The invention aims at solving the problems existing in the prior art. To achieve the above-mentioned invention, the invention provides the following technical scheme: a smoke exhaust device for cervical LEEP knife conization, comprising a LEEP knife rod, a hand-held handle is arranged on the rear side of the LEEP knife rod, a handle anti-skid pattern is arranged on the hand-held handle, an electrode plug is arranged on the rear side of the LEEP knife rod, a LEEP knife surgical knife head is arranged on the front end of the LEEP knife rod, and a smoke exhaust assembly is arranged on the LEEP knife rod.

[0006] As a preferred technical scheme of the invention, the smoke exhaust assembly comprises a smoke inlet hole and an internal smoke exhaust channel.

[0007] As a preferred technical scheme of the invention, the smoke inlet hole is arranged at a position close to the LEEP knife surgical knife head on the front end of the LEEP knife rod.

[0008] As a preferred technical scheme of the invention, a connecting hole is arranged above the end of the internal smoke exhaust channel, and the connecting hole is connected with a smoke exhaust conveying assembly.

[0009] As a preferred technical scheme of the invention, the smoke exhaust conveying assembly comprises a smoke exhaust connecting pipe, a connecting pipe threaded joint and a smoke exhaust hose, the smoke exhaust connecting pipe is connected with the smoke exhaust hose through the connecting pipe threaded joint, and the smoke exhaust hose is connected with a smoke exhaust power assembly.

[0010] As a preferred technical scheme of the invention, the smoke exhaust connecting pipe is inserted into the inside of the connecting hole.

[0011] As a preferred technical scheme of the invention, the smoke exhaust power assembly comprises a smoke exhaust motor, a motor rotating shaft, smoke exhaust helical blades, a motor mounting seat and a motor air inlet.

[0012] As a preferred technical scheme of the invention, the smoke exhaust motor is connected with the smoke exhaust helical blades through the motor rotating shaft, the smoke exhaust motor is connected with the LEEP knife rod through the motor mounting seat, and the end of the smoke exhaust motor is provided with the motor air inlet.

[0013] As a preferred technical scheme of the invention, the motor air inlet is connected with the smoke exhaust hose, and the rear side of the smoke exhaust motor is connected with the smoke exhaust connecting pipe.

[0014] As a preferred technical scheme of the invention, the LEEP knife rod is provided with a LEEP knife control switch and a smoke exhaust control switch.

[0015] Compared with the prior art, the beneficial effects of the present application: in the process of cervical LEEP knife conization, the operation will produce a large amount of smoke containing cell fragments, viruses (such as HPV) and harmful chemicals. The device can timely suck these smoke into the smoke inlet hole, and then discharge it out of the operating room through the smoke discharge inner channel and the smoke discharge conveying assembly, effectively purifying the air in the operating room and avoiding air pollution caused by smoke diffusion.

[0016] The timely discharge of smoke makes the surgical field clearer, and medical staff can more accurately observe the condition of the surgical site, clearly distinguish the boundary of the diseased tissue and the surrounding normal tissue, which helps to improve the precision of surgical operation, reduce the misoperation caused by unclear vision, and thus improve the operation quality.

[0017] The harmful substances such as viruses (such as HPV) contained in the surgical smoke will pose a serious threat to the health of medical staff if inhaled for a long time. The device can quickly discharge the smoke, greatly reducing the opportunity of medical staff to contact and inhale harmful smoke, and reducing the risk of infection and respiratory diseases, providing strong protection for the occupational health of medical staff.

[0018] Avoiding long-term exposure of medical staff to harmful smoke environment helps to reduce the incidence of chronic respiratory diseases, lung diseases and other occupational diseases caused by inhaling harmful substances, and ensures the long-term health of medical staff.

[0019] The smoke discharge assembly is integrated on the LEEP knife rod, making the whole device compact and easy to operate. Medical staff do not need to operate complex smoke discharge equipment while using LEEP knife for operation, and only need to control the work of LEEP knife and smoke discharge device through LEEP knife control switch and smoke discharge control switch, realizing the integration of operation and smoke discharge function, and improving the operation efficiency.

[0020] The smoke discharge hose has good flexibility and can flexibly adapt to different operation postures and position changes during the operation. No matter how the medical staff adjusts the operation angle and direction, the smoke discharge hose can maintain smooth smoke discharge channel to ensure that the smoke discharge effect is not affected and does not interfere with the normal operation of the operation.

[0025] Embodiment 1: A smoke exhaust device for cervical LEEP knife conization, comprising a LEEP knife rod 1, a hand-held handle 2 is arranged on the rear side of the LEEP knife rod 1, a handle anti-skid pattern 3 is arranged on the hand-held handle 2, an electrode plug 4 is arranged on the rear side of the LEEP knife rod 1, a LEEP knife surgical knife head 5 is arranged on the front end of the LEEP knife rod 1, and a smoke exhaust assembly 6 is arranged on the LEEP knife rod 1.

[0026] The smoke exhaust assembly 6 comprises a smoke inlet hole 601 and a smoke exhaust inner passage 602, and the smoke inlet hole 601 is connected with the smoke exhaust inner passage 602.

[0027] The smoke inlet hole 601 is arranged at the position close to the LEEP knife surgical knife head 5 on the front end of the LEEP knife rod 1.

[0028] The end of the smoke exhaust inner channel 602 is provided with a connecting hole 7 connected with a smoke exhaust conveying assembly 8.

[0029] The smoke exhaust conveying assembly 8 comprises a smoke exhaust connecting pipe 10801, a connecting pipe threaded joint 802 and a smoke exhaust hose 803, the smoke exhaust connecting pipe 10801 is connected with the smoke exhaust hose 803 through the connecting pipe threaded joint 802, and the smoke exhaust hose 803 is connected with a smoke exhaust power assembly 9.

[0030] The smoke exhaust connecting pipe 10801 is inserted into the inside of the connecting hole 7.

[0031] The smoke exhaust power assembly 9 comprises a smoke exhaust motor 901, a motor rotating shaft 902, smoke exhaust spiral blades 903, a motor mounting seat 904 and a motor air inlet 905.

[0032] The smoke exhaust motor 901 is connected with the smoke exhaust spiral blades 903 through the motor rotating shaft 902, the smoke exhaust motor 901 is connected with the LEEP rod 1 through the motor mounting seat 904, and the end of the smoke exhaust motor 901 is provided with the motor air inlet 905.

[0033] The motor air inlet 905 is connected with the smoke exhaust hose 803, and the rear side of the smoke exhaust motor 901 is connected with a smoke exhaust connecting pipe 10.

[0034] The LEEP rod 1 is provided with a LEEP control switch 11 and a smoke exhaust control switch 12.

[0035] Working principle: The medical staff holds the hand-held handle 2 provided with the handle anti-slip pattern 3, and stably holds the LEEP rod 1. The electrode plug 4 is connected with a power supply to provide power support for the whole device.

[0036] The LEEP control switch 11 is turned on, and the LEEP surgical knife head 5 starts to work, and the high-frequency electric wave is used to cut and electrocoagulate the cervical lesion tissue to stop bleeding.

[0037] At the moment when the smoke is generated during the operation, due to the action of the smoke exhaust power assembly 9, a negative pressure is formed in the inside of the device.

[0038] The smoke inlet hole 601 close to the LEEP surgical knife head 5 serves as an entrance of the smoke, and the smoke generated during the operation containing cell fragments, viruses (such as HPV) and harmful chemical substances is sucked in by the negative pressure. The sucked smoke is conveyed through the smoke exhaust inner channel 602 connected with the smoke inlet hole 601. The connecting hole 7 at the end of the smoke exhaust inner channel 602 plays a transfer role, and the smoke exhaust connecting pipe 10801 inserted therein connects the smoke exhaust inner channel 602 with the subsequent conveying assembly.

[0039] The smoke enters the smoke exhaust connecting pipe 10801 from the smoke exhaust inner channel 602, and then enters the smoke exhaust hose 803 through the connecting pipe threaded joint 802. The smoke exhaust hose 803 has a certain flexibility, which facilitates the adaptation to different operation postures and positions during the operation, and continuously delivers the smoke to the smoke exhaust power assembly 9.

[0040] The smoke exhaust power assembly 9 is the power core of the entire smoke exhaust process. After the smoke exhaust control switch 12 is turned on, the smoke exhaust motor 901 starts to work. The smoke exhaust motor 901 drives the smoke exhaust helical blade 903 to rotate at high speed through the motor shaft 902, forming a strong suction force to suck the smoke into the motor air inlet 905.

[0041] The smoke exhaust motor 901 is fixed on the LEEP knife rod 1 through the motor mounting seat 904, which ensures the stability of the device.

[0042] The inhaled smoke is finally discharged to the designated collection or treatment device through the smoke exhaust connecting pipe 10 connected to the rear side of the smoke exhaust motor 901, thereby avoiding the pollution of the operating room air by the smoke, ensuring the clarity of the surgical field, and reducing the risk of inhaling harmful smoke for medical staff.

[0043] Working process of the smoke exhaust device for cervical LEEP knife conization: Preoperative preparation: connect the electrode plug 4 with the corresponding power supply equipment to ensure that the LEEP knife can normally operate.

[0044] Insert the smoke exhaust connecting pipe 801 into the connecting hole 7, and firmly connect the smoke exhaust connecting pipe 801 with the smoke exhaust hose 803 through the connecting pipe threaded joint 802. Connect the smoke exhaust hose 803 with the motor air inlet 905 of the smoke exhaust power assembly 9, and connect the rear side of the smoke exhaust motor 901 with the smoke exhaust connecting pipe 10, to ensure the smoothness of the entire smoke exhaust channel.

[0045] Check the equipment. The medical staff holds the hand-held handle 2 with the anti-slip pattern 3 of the handle, checks whether the connection of the LEEP knife rod 1 and each component is stable, and ensures that there is no looseness or damage. Press the LEEP knife control switch 11 and the smoke exhaust control switch 12 respectively, test whether the LEEP knife surgical knife head 5 can normally work, and whether the smoke exhaust power assembly 9 can generate suction, to confirm that the equipment is in good working condition.

[0046] Operation: start the LEEP knife, the medical staff turns on the LEEP knife control switch 11, and the LEEP knife surgical knife head 5 generates high-frequency electric waves after being powered on, to start cutting and electrocoagulation hemostasis operation on the cervical lesion tissue. During the cutting process, a large amount of surgical smoke containing cell fragments, viruses (such as HPV) and harmful chemical substances will be generated due to the thermal decomposition of the tissue.

[0047] At the same time or after the smoke is generated, the medical staff presses the smoke exhaust control switch 12 to start the smoke exhaust power assembly 9. The smoke exhaust motor 901 starts to operate, and drives the smoke exhaust spiral blade 903 to rotate at high speed through the motor shaft 902, thereby forming a negative pressure in the device.

[0048] Smoke collection and delivery: due to the negative pressure, the smoke inlet hole 601 near the LEEP knife operating head 5 starts to inhale the smoke generated during the operation. After the smoke enters the smoke inlet hole 601, it is transported backward along the smoke exhaust inner channel 602 connected thereto. After the smoke reaches the end of the smoke exhaust inner channel 602, it enters the smoke exhaust connecting pipe 801 through the connecting hole 7, and then enters the smoke exhaust flexible pipe 803 through the connecting pipe threaded joint 802. The smoke exhaust flexible pipe 803 has a certain flexibility, which can adapt to different operation postures and position changes during the operation, and continuously deliver the smoke to the smoke exhaust power assembly 9.

[0049] Smoke exhaust: the smoke enters the smoke exhaust power assembly 9 through the motor air inlet 905, and is further sucked and discharged to the designated collection or processing device through the smoke exhaust connecting pipe 10 under the action of the smoke exhaust motor 901 and the smoke exhaust spiral blade 903, so as to avoid the smoke from diffusing in the operating room.

[0050] Postoperative treatment: turn off the device: after the operation is completed, first turn off the smoke exhaust control switch 12 to stop the work of the smoke exhaust power assembly 9, and ensure that there is no suction force. Then turn off the LEEP knife control switch 11 to stop the work of the LEEP knife operating head 5.

[0051] Disconnect the electrode plug 4 from the power supply, pull out the smoke exhaust connecting pipe 801 from the connecting hole 7, and sequentially disassemble the connecting pipe threaded joint 802, the smoke exhaust flexible pipe 803 and other assemblies. Clean and disinfect the LEEP knife rod 1, the LEEP knife operating head 5 and each smoke exhaust assembly, remove the residual smoke and impurities, and properly store them for next use.

[0052] The above examples are only used to illustrate the present application and not to limit the technical solutions described in the present application. Although the present application has been described in detail with reference to the above embodiments, the present application is not limited to the above specific embodiments, and any modification or equivalent replacement of the present application; all technical solutions and improvements without departing from the spirit and scope of the application are covered in the scope of the claims of the present application.
