Description

Technical Field

[0001] This invention relates to the field of medical scalpel technology, specifically to a laser scalpel that separates smoke and liquid suction. Background Technology

[0002] The smoke and liquid aspiration separation laser scalpel is a tool used in laser surgery. It uses laser energy to cut or vaporize tissue and removes the generated smoke and liquid through a suction system. The smoke generated during laser surgery is drawn in by the suction system on the scalpel, preventing the smoke from spreading and affecting the doctor's vision during the operation.

[0003] When doctors use a scalpel to cut tissue, the friction and cutting between the scalpel blade and the tissue generates a large amount of heat. This heat can cause the moisture on the tissue surface to evaporate and form tiny vapor particles, which constitute smoke. In addition, some scalpels have electrocoagulation cutting functions, which cut tissue through high-frequency current. This cutting method also generates high temperatures, causing tissue to evaporate and produce smoke. Furthermore, during the operation, the liquids produced may be heated and evaporated, forming hot steam, especially when it is necessary to inject liquids or use coolant.

[0004] Furthermore, the high temperature generated when the surgical electrosurgical unit cuts tissue can cause substances such as proteins and blood in the tissue to coagulate. These coagulated substances may adhere to the inner wall of the fume extraction tube, forming impurities. At the same time, the surgical smoke may contain tiny particles such as tissue fragments and cell residues. These particles may deposit on the inner wall of the tube when passing through it. The smoke generated by the surgical electrosurgical unit may also contain gases, which may deposit inside the tube under certain conditions when passing through it.

[0005] Therefore, in view of this, the present invention proposes a smoke and liquid suction separation laser surgical scalpel to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a smoke and liquid suction separation laser surgical scalpel, thereby resolving the technical issues raised in the background section.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a smoke and liquid suction separation laser scalpel, including a collection platform, a separation cylinder installed in the middle of the collection platform, an auxiliary tube scalpel connected above the separation cylinder, a contraction and extension mechanism provided inside the auxiliary tube scalpel, and an absorption cylinder pretreatment mechanism provided below the contraction and extension mechanism.

[0008] The retractable / extending mechanism is used to shield doctors from smoke during surgery;

[0009] The absorption tube pretreatment mechanism is used to automatically clean the smoke tube wall during the doctor's surgical intervals.

[0010] Furthermore, the retraction and extension mechanism includes a fixed cylinder fixedly connected to the outer wall of the scalpel tube, sliding rods symmetrically slidably connected to both sides of the fixed cylinder, a telescopic frame fixedly connected to the outer wall of the sliding rods, a movable ring fixedly connected to the end of the sliding rod away from the fixed cylinder, an adjusting ring evenly fixedly connected to the upper surface of the movable ring, a protective shell slidably connected to the outer wall of the adjusting ring, the upper end of the protective shell fixedly connected to the outer wall of the scalpel tube, hinge rods evenly hinged to the upper surface of the movable ring, connecting rods evenly hinged to the end of the hinge rod away from the movable ring, a connecting rod fixedly connected to the outer wall of the scalpel tube, a connecting rod hinged to the protective shell at the end of the connecting rod away from the fixed cylinder, and a protective sleeve fitted onto the outer wall of the scalpel tube.

[0011] Furthermore, the overall size of the protective sleeve is adapted to the size of the attached surgical scalpel, and the protective sleeve is made of silicone.

[0012] Furthermore, cylindrical protrusions are provided on both sides of the telescopic frame, and slots are provided on the inner wall of the fixed cylinder at the positions corresponding to the cylindrical protrusions.

[0013] Furthermore, the protective shell is funnel-shaped, initially in a contracted state, and is configured as a smoke barrier.

[0014] Furthermore, the absorption tube pretreatment mechanism includes branch tubes symmetrically and fixedly connected to the outer wall of the attached tube scalpel. Each branch tube has an adjusting tube fixedly connected to its outer wall. Each adjusting tube has a cleaning ring slidably connected to its inner wall. Each cleaning ring has a curved rod fixedly connected to its end away from the adjusting tube. The end of the curved rod away from the cleaning ring is fixedly connected to the outer wall of the moving ring.

[0015] Furthermore, the entire branch tube is kept in communication with the attached surgical knife, and the adjusting tube is a telescopic adjustable structure.

[0016] Furthermore, the outer wall of the cleaning ring is equipped with a removable cleaning cloth, and the crank rod is L-shaped overall.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) The protective shell can effectively block the smoke generated during surgery, which is very important for surgeons and surgical teams. The smoke may come from laser surgery, electrocautery, electrocoagulation and other processes. Blocking the smoke can improve the visibility of the surgical area, allowing doctors to see the operating area more clearly. In addition, a clearer surgical field of vision helps doctors to complete the surgical operation more quickly and accurately, thereby improving surgical efficiency. Reducing the difficulty of operation caused by smoke can make the surgical process smoother. In addition, the smoke generated during the operation may contain bacteria, viruses and other harmful substances. The automatically unfolding protective shell smoke screen helps to block these harmful substances, reduce air pollution in the operating room and improve the hygiene level of the operating room.

[0019] (2) Protecting the scalpel tube with a protective sleeve can effectively resist the corrosion of some chemicals, which helps to extend the service life of the scalpel tube. In addition, the elasticity of the protective sleeve can make it adapt to different shapes of tubes and connection parts, ensuring a tight fit. Furthermore, the insulation of the protective sleeve can also prevent external current from interfering with the surgical equipment and improve the safety of the equipment.

[0020] (3) By cleaning the inner wall of the scalpel cleaner, these deposits can be removed in time, which helps maintain the normal working condition of the scalpel, reduces the reduction of equipment performance, avoids the accumulation of dirt and impurities inside the branch cylinder due to untimely cleaning of the inner wall, which will block the channel and affect the normal operation of the equipment. In this way, the service life of the scalpel can be extended, the frequency of maintenance and replacement can be reduced, and the reliability and stability of the equipment can be improved.

The upper end of the protective shell 27 is fixedly connected to the outer wall of the attached tube scalpel 12. Hinged rods 25 are uniformly hinged to the upper surface of the movable ring 24. The end of the hinged rod 25 away from the movable ring 24 is uniformly hinged... A connecting rod 26 is attached, with one end of the connecting rod 26 away from the hinge rod 25 fixedly connected to the outer wall of the attached tube scalpel 12. The other end of the connecting rod 26 away from the fixed cylinder 21 is hinged to the protective shell 27. A protective sleeve 28 is fitted onto the outer wall of the attached tube scalpel 12. The overall size of the protective sleeve 28 is adapted to the size of the attached tube scalpel 12, and the protective sleeve 28 is made of silicone. Cylindrical protrusions are provided on both sides of the telescopic frame 23. The inner wall of the fixed cylinder 21 is provided with slots corresponding to the cylindrical protrusions. The protective shell 27 is funnel-shaped. The protective shell 27 is initially in a retracted state and is set as a smoke screen.

[0033] Specifically, the extension of the protective shell 27 can effectively block the smoke generated during surgery, which is very important for surgeons and surgical teams. The smoke may come from processes such as laser surgery, electrocautery, and electrocoagulation. Blocking the smoke can improve the visibility of the surgical area, allowing doctors to see the operating area more clearly. Furthermore, a clearer surgical field of vision helps doctors complete surgical operations more quickly and accurately, thereby improving surgical efficiency. Reducing the operational difficulties caused by smoke can make the surgical process smoother. In addition, the smoke generated during surgery may contain bacteria, viruses, and other harmful substances. The automatically deploying protective shell 27 smoke screen helps to block these harmful substances, reduce air pollution in the operating room, and improve the hygiene level of the operating room.

[0034] Please refer to Figure 6 and Figure 7 As shown, the absorption tube pretreatment mechanism 3 includes branch tubes 31 symmetrically fixedly connected to the outer wall of the attached tube scalpel 12. Each branch tube 31 has an adjusting tube 32 fixedly connected to its outer wall. Each adjusting tube 32 has a cleaning ring 34 slidably connected to its inner wall. Each cleaning ring 34 has a curved rod 33 fixedly connected to its end away from the adjusting tube 32. Each curved rod 33 has a fixed connection to the outer wall of the moving ring 24 at its end away from the cleaning ring 34. The entire branch tube 31 is in communication with the attached tube scalpel 12. The adjusting tube 32 is a telescopic adjustable structure. Each cleaning ring 34 has a detachable cleaning cloth installed on its outer wall. The curved rod 33 is L-shaped.

[0035] Specifically, by cleaning the inner wall of the scalpel cleaner, these accumulated materials can be removed in a timely manner, which helps maintain the normal working condition of the scalpel, reduces the degradation of equipment performance, and prevents the accumulation of dirt and impurities inside the branch cylinder 31 from clogging the channel due to untimely cleaning, thus affecting the normal operation of the equipment. In this way, the service life of the scalpel can be extended, the frequency of maintenance and replacement can be reduced, and the reliability and stability of the equipment can be improved.

[0036] The following are the complete usage steps and working principle of the above embodiments:

[0037] This device is mainly used for: smoke and liquid aspiration separation laser scalpel is mainly used in surgical procedures, especially those that require the use of laser technology. This device is mainly used in various surgical procedures, such as ophthalmic surgery, skin surgery, oral and maxillofacial surgery, etc. Laser technology is often used in these fields to cut, ablate or coagulate tissue.

[0038] The retractable and extendable mechanism 2, used to shield doctors from smoke during surgery, is specifically used as follows:

[0039] When the doctor is ready to use the scalpel device for surgery, they can directly pull the adjusting ring 2401 upwards. At this time, the moving ring 24, which is fixedly connected to the adjusting ring 2401, will move upwards synchronously with the adjusting ring 2401 along the inner wall of the fixed cylinder 21 through the sliding rod 22. This continues until the telescopic frame 23, which is fixedly connected to the outer wall of the sliding rod 22, is once again engaged in the slot on the inner wall of the fixed cylinder 21 during the upward movement. At this point, the doctor stops pulling the adjusting ring 2401. The telescopic frame 23, which is engaged in the slot on the inner wall of the fixed cylinder 21, remains stationary, thus preventing the adjusting ring 2401 from sliding downwards. As the moving ring 24 moves upwards synchronously with the adjusting ring 2401, it continuously pushes the hinge rod 25, which is hinged to the connecting rod 26, upwards, causing it to expand in all directions. Since the protective shell 27 is made of smoke-proof curtain material, the connecting rod 26, which keeps expanding in all directions, will drive the smoke-proof curtain to expand in all directions. The protective shell 27 expands outwards in sync with the surrounding area, causing the protective shell 27, which is retracted outside the scalpel tube 12, to gradually extend upwards. This ensures that the surgical head area of ​​the scalpel tube 12 can be used normally. The extension of the protective shell 27 can effectively block the smoke generated during surgery, which is very important for surgeons and surgical teams. The smoke may come from processes such as laser surgery, electrocautery, and electrocoagulation. Blocking the smoke can improve the visibility of the surgical area, allowing doctors to see the operating area more clearly. Furthermore, a clearer surgical field of vision helps doctors complete surgical operations more quickly and accurately, thereby improving surgical efficiency. Reducing the operational difficulties caused by smoke can make the surgical process smoother. In addition, the smoke generated during surgery may contain bacteria, viruses, and other harmful substances. The automatically unfolding protective shell 27 smoke screen helps to block these harmful substances, reduce air pollution in the operating room, and improve the hygiene level of the operating room.

[0040] Since the outer wall of the attached surgical scalpel 12 is covered with a protective sleeve 28, and the protective sleeve 28 is made of silicone, silicone can maintain its softness and elasticity at low temperatures and is not easy to harden or become brittle. At the same time, silicone is compatible with human tissue and is not likely to cause allergic or rejection reactions. It also has good stability against many chemicals. Therefore, by protecting the attached surgical scalpel 12 with the protective sleeve 28, it can effectively resist the corrosion of some chemicals and help extend the service life of the attached surgical scalpel 12 tube. In addition, the elasticity of the protective sleeve 28 can make it adapt to tubes and connection parts of different shapes, ensuring a tight fit. Furthermore, the insulation of the protective sleeve 28 can also prevent external current from interfering with the surgical equipment and improve the safety of the equipment.

[0041] The absorption tube pretreatment mechanism 3, used for automatically cleaning the smoke tube walls during surgical intervals, is specifically used as follows:

[0042] Because the outer wall of the scalpel 12 is symmetrically equipped with branch tubes 31 for absorbing smoke and liquid, during prolonged surgeries, the branch tubes 31 inevitably inhale the patient's internal cells, tissues, and other substances. Since the adjusting tube 32 is adjustable and contains a cleaning cloth, during extended surgeries, the doctor can directly push or pull the adjusting ring 2401. This moves the crank rod 33 up and down via the moving ring 24, allowing the cleaning ring 34 inside the adjusting tube 32 to clean the inside of the branch tubes 31. When the branch tubes 31 absorb smoke and liquid, they may carry impurities and particles that accumulate on their inner wall. Cleaning the inner wall with the cleaning ring 34 removes these deposits, helping to maintain the scalpel's normal operating condition, reducing equipment performance degradation, and preventing the accumulation of dirt and impurities that can clog the channels and affect normal operation. This extends the scalpel's lifespan, reduces maintenance and replacement frequency, and improves equipment reliability and stability.
