TECHNICAL FIELD
[0001] The present application relates to the technical field of laparoscopic surgery equipment, in particular to a laparoscopic pneumoperitoneum pressure and anesthesia ventilation combined control device for hepatobiliary surgery. BACKGROUND
[0002] Laparoscopic surgery needs to establish an artificial abdomen, and the pneumoperitoneum pressure affects anesthesia ventilation. At present, the commonly used ventilation mode for laparoscopic surgery is the pressure mode (PCV), so that the progress of laparoscopic surgery can be ensured, and the airway pressure is relatively stable, which can ensure the ventilation volume.
[0003] However, in the actual operation process, the pneumoperitoneum pressure of the patient often changes, and even in the pressure control mode, ventilation deficiency or excess may occur, which affects the intra-abdominal environment. The existing laparoscopic device cannot effectively and timely measure and respond to the intra-abdominal pressure, and cannot automatically adjust and control the pressure, which is not conducive to the stable control of the pneumoperitoneum pressure.
[0004] In view of this, the present application provides a laparoscopic pneumoperitoneum pressure and anesthesia ventilation combined control device for hepatobiliary surgery to solve the above-mentioned problems. SUMMARY

[0024] Embodiment:
[0025] [[ID=2*]]Please refer to Figs. 1-2 , this embodiment provides a combined regulation device for laparoscopic pneumoperitoneum pressure and anesthesia ventilation in hepatobiliary surgery, which includes a connector 1. A connection port 11 is provided at the top of the connector 1. A pressure chamber 2 is provided inside the connector 1. A measurement chamber 3 is connected and provided on one side of the pressure chamber 2; a first sliding plate 4 is provided inside the measurement chamber 3. A return spring 5 is provided on one side of the first sliding plate 4. The inner diameter of the measurement chamber 3 is smaller than the inner diameter of the pressure chamber 2; a sealing ring 1* is provided inside the connection port 11, and the cross-section of the sealing ring 12 is arranged in a "C" shape.
[0026] It should be noted that there seems to be an error in the original text where "密封环12" is incorrectly written as "密封环1*" in the translation of line . I have translated it as "密封环12" as per the correct text. If this is not what you intended, please correct the original text for a more accurate translation.Existing laparoscopic devices cannot effectively and promptly measure and respond to intra-abdominal pressure, nor can they automatically adjust and control pressure, which is detrimental to the stable control of pneumoperitoneum pressure. This invention, through a pressure chamber 2 within the connector 1, allows the patient's intra-abdominal pressure to be transmitted to the measuring chamber 3, creating a pushing pressure on the first sliding plate 4. Combined with the return spring 5, this allows medical personnel to quickly observe the pressure by moving the first sliding plate 4, effectively preventing situations where rapid pressure changes cause patient discomfort and prevent medical personnel from reacting effectively. Simultaneously, the inner diameter of the measuring chamber 3 is smaller than that of the pressure chamber 2, making the first sliding plate 4 more sensitive to changes in intra-abdominal pressure. A U-shaped sealing ring 12 on the inner side of the connector 11 seals the connecting tube, preventing leakage.
[0027] In some embodiments of the present invention, an annular groove is provided on the inner side of the connection port 11, and a sealing member 13 is provided below the upper connection port 11. A connecting ring adapted to the annular groove is provided on the sealing member 13, and the connecting ring is connected to the annular groove through an elastic member 15. An opening 14 is provided on the side of the connecting ring. Medical personnel can insert a ventilation device to open the sealing member 13, so that the side of the connecting ring communicates with the outside of the opening 14. After the ventilation device is pulled out, the elastic member 15 pulls back the sealing member 13 to seal it.
[0028] In some embodiments of the present invention, the measuring cavity 3 is provided with scale lines. The scale lines allow medical personnel to visually determine the patient's ascites pressure by observing the position of the first sliding plate 4 within the measuring cavity 3. It is understood that the connector 1 is made of a transparent material for easy observation.
[0029] In some embodiments of the present invention, a second sliding plate 6 is disposed above the first sliding plate 4, and a return spring 5 is connected to the second sliding plate 6; a protective plate 7 is disposed at the upper end of the second sliding plate 6, and a protective fluid 9 is filled between the second sliding plate 6 and the protective plate 7; rubber rings 8 are disposed on the outer sides of both the second sliding plate 6 and the protective plate 7. The protective fluid 9 is physiological saline. The rubber rings 8 disposed on the outer sides of the second sliding plate 6 and the protective plate 7 provide a certain resistance to the measuring cavity 3 and eliminate gaps. The protective fluid 9 ensures a good seal, preventing contamination from contact with the outside. The first sliding plate 4 and the second sliding plate 6 are connected by the return spring 5, so that when the return spring 5 is subjected to excessive pressure, it can push the second sliding plate 6 to move and adjust the pressure in a timely manner.
[0030] In some embodiments of the present invention, an adjustment pipe 16 is provided in the pressure chamber 2, and a pressure adjustment valve 17 is provided on the adjustment pipe 16; a pressure pipe is connected to the adjustment pipe 16, and a pressure adjustment plate 18 is included in the pressure pipe, and a threaded control rod 20 is provided on the pressure plate; the inner diameter of the pressure pipe is larger than the inner diameter of the pressure chamber 2. By opening and closing the pressure adjustment valve 17, medical staff can, after observing the pneumoperitoneum pressure, move the pressure adjustment plate 18 by rotating the threaded control rod 20, so that the pneumoperitoneum pressure can be effectively adjusted through the adjustment pipe 16; the inner diameter of the pressure pipe is larger than the inner diameter of the pressure chamber 2, and the pressure condition can be adjusted quickly.
[0031] In some embodiments of the present invention, a sealing rubber 19 is provided on the outer side of the pressure adjustment plate 18, and the thickness of the upper and lower ends of the sealing rubber 19 is greater than that of its middle part, which can well avoid the situation of air leakage. A sliding sealing film 10 is provided in both the measurement chamber 3 and the adjustment pipe 16. The setting of the sealing film can further avoid gas leakage.
[0032] In summary, the embodiments of the present invention provide a combined regulation device for pneumoperitoneum pressure and anesthesia ventilation in laparoscopic hepatobiliary surgery, which includes a connection head 1. A connection port 11 is provided at the top of the connection head 1, a pressure chamber 2 is provided in the connection head 1, and a measurement chamber 3 is connected to one side of the pressure chamber 2; a first sliding plate 4 is provided in the measurement chamber 3, a return spring 5 is provided on one side of the first sliding plate 4, and the inner diameter of the measurement chamber 3 is smaller than the inner diameter of the pressure chamber 2; a sealing ring 12 is provided inside the connection port 11, and the cross-section of the sealing ring 12 is arranged in a "C" shape. Through the pressure chamber 2 provided in the connection head 1 of the present invention, the intra-abdominal pressure of the patient can be communicated to the measurement chamber 3 through the pressure chamber 2, forming a pushing pressure on the first sliding plate 4. With the setting of the return spring 5, medical staff can quickly observe the pressure condition through the movement of the first sliding plate 4, effectively avoiding the situation that the patient feels uncomfortable due to too rapid pressure change and medical staff cannot effectively respond; at the same time, the inner diameter of the measurement chamber 3 being smaller than the inner diameter of the pressure chamber 2 makes the first sliding plate 4 more sensitive to the change of intra-abdominal pressure; the sealing ring 12 provided inside the connection port 11 can block the connected communication pipe to avoid leakage.
[0033] The above are only the preferred embodiments of the present invention and are not used to limit the present invention.
