As shown in fig. 1 to 3, a laparoscopic surgical defogging device 1 according to a first preferred embodiment of the present utility model is schematically illustrated. The laparoscopic surgery defogging device 1 is used to remove smoke generated in laparoscopic surgery. The laparoscopic surgery defogging device 1 is suitable for storing liquid, and when laparoscopic surgery operation is performed, the laparoscopic surgery defogging device 1 is in butt joint with the exhaust valve of the puncture outfit 8 for laparoscope, and surgery smoke is automatically led out, so that the visual field of laparoscopic surgery is clear.

The laparoscopic surgery defogging device 1 has two states, an operating state and a non-operating state. Before laparoscopic surgery, laparoscopic surgery defogging device 1 is in the non-operating condition, and medical personnel carries out the notes liquid operation to laparoscopic surgery defogging device 1 is interior. In the laparoscopic surgery, the laparoscopic surgery defogging device 1 is in an operating state, at this time, the laparoscopic surgery defogging device 1 is abutted against the exhaust valve of the laparoscopic puncture outfit 8, and the surgical smoke is removed by the laparoscopic surgery defogging device 1.

The laparoscopic surgical defogging device 1 includes a body member 10 and a connecting member 20. The body member 10 provides an installation space within which the body member 10 is adapted to store a liquid for removal of surgical fumes. The connection member 20 is connected to the body member 10. The main body member 10 is connected to an exhaust valve of the laparoscopic puncture instrument 8 through the connection member 20. In a refinement, the inside of the main body member 10 is communicated with the exhaust valve of the laparoscopic puncture outfit 8 through the connecting member 20. Stated another way, smoke generated during laparoscopic surgery is discharged from the exhaust valve of the laparoscopic puncture device 8 to the body member 10 through the connection member 20 to be removed. Before laparoscopic surgery, a medical staff performs a irrigating operation on the body member 10. When laparoscopic surgery is performed, smoke generated during laparoscopic surgery is introduced into the body member 10 through the connection member 20.

Specifically, the body member 10 includes a bag 11 having a receiving cavity 12. In this embodiment, the main body member 10 is implemented as the pouch 11 to be clamped and fixed to the surgical drape by a clamping member 30. The receiving chamber 12 is adapted to store a liquid, which in this embodiment is embodied as water. That is, a health care provider may inject water into the receiving chamber 12 to remove smoke generated during laparoscopic surgery.

The body member 10 further has a mounting hole 13 and a vent passage 14, the mounting hole 13 and the vent passage 14 being provided at the top of the bag body 11. In a refinement, the mounting hole 13 and the air exhaust channel 14 penetrate through the top of the bag 11. The mounting hole 13 is adapted to mount the connection member 20, and the exhaust passage 14 always communicates the accommodating chamber 12 with the outside air. The connection member 20 is fixedly mounted to the bag body 11 through the mounting hole 13. When the laparoscopic surgery defogging device 1 is in an operating state, the surgery smoke is finally discharged to the outside through the exhaust passage 14; when the laparoscopic surgical defogging device 1 is not in operation, a medical staff injects water into the inside of the accommodating chamber 12 through the air discharge channel 14.

The connecting member 20 includes a tube 21 and has a communication passage 22, and the tube 21 is fixedly mounted to the bag 11. The tube 21 is adapted to pass through the mounting hole 13. The tube 21 is fixedly attached to the bag 11 through the attachment hole 13. One end of the tube 21 is located outside the bag 11, and the other end is located in the accommodating chamber 12. The vent valve of the laparoscopic puncture outfit 8 is adapted to be connected to the bag 11 through the tube 21. The communication passage 22 penetrates both end surfaces of the pipe body 21. When the laparoscopic surgery defogging device 1 is in an operating state, the tube body 21 is connected with the exhaust valve of the laparoscopic puncture outfit 8, and the exhaust valve of the laparoscopic puncture outfit 8 is abutted with the communication channel 22. At this time, the communication passage 22 communicates the inside of the laparoscopic surgery chamber with the inside of the bag body 11.

Further, the tube 21 includes an outer tube 211 and an inner tube 212. The outer tube 211 extends outwardly from the mounting hole 13, and the inner tube 212 extends inwardly from the mounting hole 13. The outer tube 211 is externally abutted with the exhaust valve of the laparoscopic puncture outfit 8, and the inner tube 212 extends inwards in the accommodating cavity 12.

It should be noted that, when the laparoscopic surgery defogging device 1 is in the non-operating state, the medical staff needs to inject water into the accommodating cavity 12 through the air exhaust channel 14 until the water passes through the lower end surface of the inner tube 212, that is, the lower end surface of the inner tube 212 is always kept below the horizontal plane. Stated another way, the communication passage 22 is maintained to be communicable to the inside of the liquid. When the laparoscopic surgery defogging device 1 is in a working state, the laparoscopic surgery defogging device 1 is clamped and fixed on a surgical drape below a laparoscopic surgery cavity plane by the clamping member 30 so as to obtain gravitational potential energy generated by relative position difference.

It is further worth mentioning that the smoke generated by the laparoscopic surgery is guided into the accommodating chamber 12 through the communication channel 22. Since the lower end surface of the inner tube 212 is positioned below the horizontal plane, the surgical smoke is introduced into the liquid in the accommodating chamber 12, and the surgical smoke is partially absorbed and converted by the liquid and partially discharged to the outside through the air discharge passage 14. The liquid in the accommodating cavity 12 is ensured not to flow back into the laparoscopic surgery cavity through the communication channel 22 to influence the operation by the gravitational potential energy generated by the stable pneumoperitoneum pressure generated by injecting carbon dioxide gas into the surgery cavity under the automatic induction of the pneumoperitoneum machine in the surgery process and the relative position difference.

The laparoscopic surgical defogging device 1 further comprises the clamping member 30 and an opening and closing member 40. The clamping member 30 includes a clamping unit 31 and a clamping mounting unit 32, and the clamping unit 31 has a clamping function. When the laparoscopic surgery defogging device 1 is in an operating state, a medical staff can clamp and fix the laparoscopic surgery defogging device on a surgical drape through the clamping unit 31. In the present embodiment, the clamping unit 31 may be implemented as a clip. The clamp unit 31 is attached to the bag body 11 by the clamp attachment unit 32. In this embodiment, the clamping and mounting unit 32 is located at the top of the bag 11, and when the liquid is poured into the bag 11, the bag 11 is clamped and fixed on the surgical drape by the clamping unit 31, so that the air exhaust channel 14 is opened upwards under the influence of gravity, and the liquid in the accommodating cavity 12 is prevented from flowing out during air exhaust.

The opening and closing member 40 is mounted on the top of the bag 11, the opening and closing member 40 includes an opening and closing unit 41 and an opening and closing mounting unit 42, the opening and closing unit 41 is openably and closably mounted on the top of the bag 11, and the opening and closing unit 41 is mounted on the bag 11 through the opening and closing mounting unit 42. The opening and closing unit 41 is located between the mounting hole 13 and the exhaust passage 14.

In the present embodiment, the opening and closing unit 41 is openably and closably arranged between the mounting hole 13 and the exhaust passage 14. The opening and closing unit 41 is fixed near one end of the mounting hole 13, and is openably and closably arranged near the exhaust passage 14 side. The opening and closing member 40 further has an opening and closing passage 43, and a passage formed between both sides of the opening and closing unit 41 in the opened state is defined as the opening and closing passage 43. The open-close passage 43 is communicably adjacent to the exhaust passage 14. When the laparoscopic surgery defogging device 1 is in a non-operating state, a medical staff expands the opening and closing channel 43 by opening the opening and closing unit 41. The opening and closing passage 43 communicates with the exhaust passage 14. At this time, the open-close channel 43 is communicated with the exhaust channel 14, which is more beneficial for medical staff to inject the liquid into the accommodating cavity than the single exhaust channel 14. At this time, the open-close passage 43 and the exhaust passage 14 together constitute a passage for injecting liquid. When the laparoscopic surgical defogging device 1 is in an operating state, the opening and closing unit 41 is closed, the opening and closing passage 43 is closed, and only the exhaust passage 14 is kept to communicate with the accommodating chamber 12 and the outside. At this time, in the demisting process, the liquid is not easy to flow out to the outside through the exhaust channel 14, so that the influence on the operation environment and the normal demisting of the laparoscopic operation demisting device 1 is avoided.

Fig. 3 is a schematic view showing an operation state of the laparoscopic surgery defogging device 1 according to the present utility model. The laparoscopic surgery defogging device 1 is butted with the exhaust valve of the laparoscopic puncture outfit 8 through the outer tube body 211, and the laparoscopic surgery defogging device 1 is kept below the laparoscopic surgery cavity plane. At this time, smoke generated by the laparoscopic surgery is guided into the accommodating chamber 12 filled with water through the communicating channel 22. The lower end surface of the inner tube 212 is maintained below the horizontal plane within the receiving cavity 12. The surgical smoke is partially absorbed and converted by water, partially released into the accommodating cavity 12, and finally discharged to the outside through the exhaust channel 14, thereby completing the elimination of the surgical smoke.

In this embodiment, the liquid injected into the accommodating cavity may be implemented as water or other solution capable of dissolving harmful substances in the surgical smoke, and when the surgical smoke is introduced into the solution through the laparoscopic surgical defogging device 1, part of the harmful substances can be reacted to keep the gas discharged outwards from the exhaust channel 14 nontoxic and pollution-free, so as to avoid the medical staff from being injured by the harmful gas.
