Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a smoking device during laparoscopic surgery. Background Art

[0002] Laparoscopic surgery is a minimally invasive method, which is increasingly used in surgery, so that many open surgeries in the past have been replaced by endoscopic surgery. The current laparoscopic surgery is a surgery performed by modern high-tech medical technology using advanced electronic, optical and other equipment principles. It is a cross-era progress in traditional laparotomy. It is a surgery performed in a closed abdominal cavity: the camera system, under the illumination of a good cold light source, is connected to the lens assembly in the abdominal cavity to capture the organs in the abdominal cavity on the monitoring screen. The surgeon, under the monitoring and guidance of the high-tech display screen, manipulates the surgical instruments outside the abdominal cavity to perform operations such as exploration, electrocoagulation, hemostasis, tissue separation and incision, and suturing of the diseased tissue.

[0003] During laparoscopic surgery, tools such as electric hooks and ultrasonic knives are used. In the process of cutting tissue, not only bleeding will occur, but also smoke will appear. The smoke will affect the line of sight and make it impossible to continue the operation. Therefore, during the operation, the smoke needs to be sucked out before the tissue can be clearly seen on the monitoring screen and the operation can be performed. The existing smoke suction is mainly done through an aspirator, but the aspirator is usually intermittent. It is only used when there is smoke or the smoke is large, or when there is a lot of bleeding. The intermittent use of the aspirator will affect the efficiency of the operation and cannot suck away the smoke in time, affecting the line of sight of the operation. In addition, the existing disposable aspirator has a large lumen and no adjustable device. While discharging the smoke, the abdominal cavity pressure drops rapidly, and the surgical space disappears, affecting the operation process and the operation of the surgeon, thereby prolonging the operation time, increasing the patient's pain, and increasing medical expenses.

[0004] In summary, there is an urgent need to design a laparoscopic intraoperative smoking device that overcomes the above-mentioned problems. Utility Model Content

[0036] The suction tube 2, the smoking tube 3 and the negative pressure connecting tube 4 are respectively connected to the three-way tube 1 through the adapter 7. The connection between the suction tube 2 and the smoking tube 3 and the adapter 7 is also provided with a flow regulating component 8, which can adjust the flow of absorbing smoke and absorbing liquid as needed, and can also control the on-off of the suction tube 2 and the smoking tube 3 respectively, so that smoking and sucking liquid can be carried out separately and independently, so as not to be affected by the use demand, that is, sucking liquid can be used intermittently as needed, while smoking can be carried out continuously, and the smoke can be sucked away in time.

[0037] Preferably, the adapter 7 includes an integrally connected first pipe section 71 and a second pipe section 72, the outer wall of the first pipe section 71 is provided with an external thread 711, the inner walls of the three ports of the three-way pipe 1 are respectively provided with first internal threads 11 matching the external threads 711, the first pipe section 71 is threadedly connected to the three-way pipe 1, and the second pipe section 72 is respectively plugged with the suction pipe 2, the smoking pipe 3 and the negative pressure connecting pipe 4. When connecting, the first pipe section 71 of the adapter 7 is threadedly connected to the port of the three-way pipe 1, and then the suction pipe 2, the smoking pipe 3 and the negative pressure connecting pipe 4 are respectively plugged with the second pipe sections 72 of the three adapters 7 to ensure that they are tightly connected.

[0038] Preferably, the flow regulating assembly 8 comprises a connecting pipe 81 detachably connected to one end of the first pipe section 71 away from the three-way pipe 1 and an adjusting seat 82 connected to the other end of the connecting pipe 81, wherein a cavity 821 is provided inside the adjusting seat 82, and a through hole 822 communicating with the cavity 821 is formed at the lower end of the adjusting seat 82, and the through hole 822 coincides with the axis of the connecting pipe 81;

[0039] The top wall of the adjustment seat 82 is threadedly connected to an adjustment bolt 83 , and the top wall of the adjustment seat 82 is provided with an internal threaded hole 823 matching the adjustment bolt 83 .

[0040] Specifically, during the connection, firstly, the two groups of connecting tubes 81 and the adjusting seat 82 are respectively put on the suction tube 2 and the smoking tube 3, and then one end of the first tube section 71 of the adapter 7 is connected to the port of the three-way tube 1, and then the suction tube 2, the smoking tube 3 and the second tube section 72 of the adapter 7 are respectively plugged; then, the connecting tube 81 is screwed on the first tube section 71 of the adapter 7 to ensure that the connection is tight. During the operation, the adjusting bolt 83 can be screwed to move it downward or upward, so that the lower end thereof can press or not press the smoking tube and the suction tube, so as to achieve the function of closing the pipeline and adjusting the flow, so as to facilitate the control of the on-off of the pipeline and the adjustment of the flow. The appropriate smoking flow and suction flow can avoid the rapid decrease of the abdominal cavity pressure, relieve the patient's pain, save the operation time and improve the operation efficiency.

[0041] Preferably, the inner wall of the connecting pipe 81 is provided with a second inner thread 811 matching the outer thread 711, and the connecting pipe 81 is connected to the adapter 7 via the thread, which has a better connection effect and is more convenient to operate.

[0042] Preferably, a connecting frame 84 is fixedly connected to both sides of the side wall between the adjustment seat 82 and the connecting pipe 81. The setting of the connecting frame 84 can make the second pipe section 72 of the adapter 7 located at its lower end, rather than in the adjustment seat 82, so as to avoid the adjustment bolt 83 from pressing on the soft smoking pipe 3 or suction pipe 2, and avoid it from pressing on the hard adapter 7, resulting in invalid flow regulation. The three-way pipe 1 and the adapter 7 are both hard pipes. The connecting frame 84 can be a connecting rod, a connecting plate or a connecting block, as long as it can achieve the function of connecting the adjustment seat 82 and the connecting pipe 81 and does not affect the passage of the pipeline.

The spring 86 can prevent the bolt from detaching from the adjusting seat 82.

[0045] Preferably, the second tube section 72 on the adapter 7 has different diameters, so as to be respectively plugged with the suction tube 2 , the smoking tube 3 and the negative pressure connecting tube 4 of different diameters.

[0046] The diameter of the smoking tube 3 in the present device is smaller than that of the suction tube 2. When the flow rate is adjusted to the maximum, smoke can be continuously discharged during the operation. The continuous suction of smoke has no significant effect on the intra-abdominal pressure. At the same time, the smoke generated in the abdominal cavity during the operation can be sucked out in time and effectively, reducing smoke interference, and the intraoperative field of vision is clear. The frequent entry and exit to wipe the mirror during the operation is reduced, so the operation is more efficient. In actual operation, the existing suction tube can also be cut into two sections of 1 / 3 and 2 / 3 length, respectively used as the suction tube 2 and the negative pressure connecting tube 4, and then the three interfaces of the three-way tube 1 are respectively connected to the two ports of the two sections of the suction tube and an interface of the smoking tube to form three passages. The other ends of the suction tubes at both ends are respectively connected to the aspirator and the negative pressure device, and the other end of the smoking tube is connected to the switch port of the laparoscope sheath card. When continuous smoking is required during the operation, the assistant can assist in opening the negative pressure device and the corresponding flow regulating component 8 to suck out the smoke.

[0047] The present invention is further described above in conjunction with the embodiments, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
