Background
In laparoscopic surgery, in order to provide a sufficient space in the abdominal cavity for observation and operation, it is necessary to provide air pressure using a pneumoperitoneum machine to enlarge the abdominal cavity. When the pneumoperitoneum machine in the prior art works, the pressure in the abdominal cavity is lower than a set value at the beginning stage of inflation, and the air pressure in the abdominal cavity is gradually increased along with the increase of gas introduced into the abdominal cavity. When the pressure in the abdominal cavity reaches a set value, the inflation is stopped. Along with the operation, the air leakage of the abdominal cavity occurs along with the actions of the entry and exit of surgical instruments, the irrigation of the abdominal cavity, the suction of tissue fluid, the taking of samples and the like, and the pressure in the abdominal cavity is reduced. When the air pressure is lower than the set value, the pneumoperitoneum machine is used again for inflation. The "inflation-pressure measurement" process of the prior art pneumoperitoneum machine is referred to as a work cycle. The whole operation process is repeatedly repeated, and a working cycle is formed, namely, the periodic impact pressure is formed. The impact pressure value varies with gas leakage during the operation. Meanwhile, in the operation process, when the electrotome in the puncture outfit cauterizes or electrically coagulates human tissues, a large amount of smoke and water vapor are inevitably generated, the smoke generated by the combustion of the organic matters is a strong carcinogen, unnecessary injuries can be caused to operators and medical staff in an operating room, and when the deep operation of a human body is carried out, particularly when important organs such as deep blood vessels are electrocauterized, the smoke can obscure an electron microscope inside, the sight of the medical staff is influenced, the hemostasis difficulty is caused, even the operation is blind or busy, and therefore the smoothness of the operation is ensured by the smoke removing device.

The embodiment provides a spiral airtight method for operation, and the air pressure in the abdominal cavity is stable, so that the operation is facilitated.
Referring to fig. 1, it should be noted that, the spiral air-tight method for operation is applied to the puncturing element 100, the puncturing element 100 has an air inlet through hole 110 and an operation through hole 120 which are independent from each other, the air inlet through hole 110 and the operation through hole 120 extend in the same direction, and the air inlet through hole 110 may be disposed around the operation through hole 120. The piercing element 100 is further provided with a gas transmission hole 130 and a gas discharge hole 140 both communicating with the operation through hole 120, the gas transmission hole 130 being located at an end of the gas discharge hole 140 remote from the operation through hole 120 for extending into the abdominal cavity, in other words, the gas transmission hole 130 is located higher than the gas discharge hole 140 with reference to the position of the piercing element 100 in the normal use state.
In this embodiment, the surgical spiral airtight method comprises the steps of:
step s100, inserting the puncture element 100 into the abdominal cavity to communicate the distal end of the operation through hole 120 with the abdominal cavity, exposing the air delivery hole 130 and the exhaust hole 140 outside the abdominal cavity, and closing the proximal end of the operation through hole 120, the air delivery hole 130 and the exhaust hole 140; the distal end of the operation through hole 120 is the end in contact with the patient, and the proximal end of the operation through hole 120 is the end in contact with the operator. The gas transmission hole 130 and the gas exhaust hole 140 are exposed outside the abdominal cavity, are not easily limited by the position of the abdominal cavity, and are convenient for gas transmission and gas exhaust operations.
Step s200, inflating the abdominal cavity by using the air inlet through hole 110 to enable the air pressure in the abdominal cavity to reach the set air pressure; can set up pressure sensor on puncture piece 100, at the inflation in-process, pressure sensor real-time detection abdominal cavity's pressure parameter to transmit pressure parameter to the controller, when pressure parameter that detects when being located the pressure range of predetermineeing in the controller, remind art person intra-abdominal cavity internal pressure to reach the default, do benefit to and carry out operation on next step. It should be understood that an alarm can be set to be in communication connection with the controller, the alarm can be one of an audible alarm, an optical alarm or an audible and visual alarm, and when the pressure parameter reaches a set value, the controller controls the alarm to give an alarm, so that the operation safety is high. In addition, the pressure parameters can be transmitted to the display and displayed in real time, so that the operator can conveniently obtain the pressure parameters, and the safety of the operation is further improved.
Step s300, in a state that the abdominal cavity is inflated by the air inlet through hole 110, the proximal end of the operation through hole 120, the air delivery hole 130 and the air exhaust hole 140 are opened, air is introduced into the operation through hole 120 by the air delivery hole 130, and the air forms a spiral air curtain 300 under the drainage of the drainage body 200. The spiral air curtain 300 blocks the gas escaping from the operation through hole 120, and the spiral air curtain 300 is understood to spirally seal the operation through hole 120, and the operation through hole 120 is used for the medical instrument to pass through, that is, the medical instrument is inserted from the proximal end of the operation through hole 120 and extends out from the distal end of the operation through hole 120 during the operation, so as to enter the abdominal cavity for the corresponding operation. Since the spiral air curtain 300 is formed in the operation through hole 120, the medical instrument passes through the spiral air curtain 300, the spiral air curtain 300 does not affect the range of motion of the medical instrument, and the medical instrument is flexible to operate. In the prior art, a sealing element needs to be arranged in the operation through hole 120, the sealing element and the medical instrument are structurally sealed, that is, the medical instrument needs to move relative to the sealing element, and the sealing property between the sealing element and the medical instrument needs to be ensured in a moving state.
During the operation, the gas entering the abdominal cavity into the operation through hole 120 is restrained in the abdominal cavity under the guidance of the spiral air curtain 300. Because the spiral air curtain 300 is formed in the operation through hole 120, when the gas exhausted from the abdominal cavity flows to the near end (the end for inserting the surgical instrument) of the operation through hole 120 and reaches the position of the spiral air curtain 300, the gas is blocked by the spiral air curtain 300 and cannot overflow from the near end of the operation through hole 120, the gas in the abdominal cavity cannot be leaked, and therefore, the gas sealing is realized.
The present embodiment provides a spiral airtight method for surgery, in which a surgical instrument is inserted from the proximal end of the operation through hole 120 and is protruded from the distal end during the surgery. Because the spiral air curtain 300 is formed in the operation through hole 120, the surgical instrument passes through the area enclosed by the spiral air curtain 300 and enters the abdominal cavity, the air barrier formed by the spiral air curtain 300 cannot interfere with the movement of the surgical instrument, namely, the sealing performance of the spiral air curtain 300 cannot be weakened by the movement of the surgical instrument, the spiral air curtain 300 cannot interfere with the movement of the surgical instrument, the two do not interfere with each other, the operation of the surgical instrument is flexible and convenient, the leakage of air cannot be caused in the operation process of the surgical instrument, and the sealing performance of the spiral air curtain 300 is high;
because the spiral air curtain 300 is formed in the operation through hole 120, the gas entering the operation through hole 120 from the abdominal cavity is not easy to break the spiral air curtain 300 and leak from the near end of the operation through hole 120, and can be inhibited in the abdominal cavity, so that the abdominal cavity pressure stabilizing effect is improved, and the gas entering the operation through hole 120 from the abdominal cavity can be driven by the spiral air curtain 300 to move together when contacting with the spiral air curtain 300, so that the gas is dispersed from the middle part to the periphery, the gas pressure entering the operation through hole 120 from the abdominal cavity is dispersed, and the condition that the pressure is concentrated in the middle part of the operation through hole 120 can not occur, so that the gas pressure in the middle part of the operation through hole 120 is reduced, the pressure required by the gas in the sealed abdominal cavity of the spiral air curtain 300 is reduced, a pressurizer is not required to pressurize the gas entering the operation through hole 120 from the gas delivery hole 130 to form the spiral air curtain 300, and the energy is saved; and when part of the gas discharged from the abdominal cavity moves along with the spiral air curtain 300, the gas participates in forming the spiral air curtain 300, so that the self-sealing effect is achieved, and the air-tightness effect is good. External air can continuously enter the abdominal cavity from the air inlet through hole 110 so as to ensure that the pressure in the abdominal cavity is stabilized at a set value. Meanwhile, the gas in the operation through hole 120 is continuously discharged from the gas discharge hole 140, the gas discharged from the gas discharge hole 140 can enter the operation through hole 120 from the gas transmission hole 130 to form a spiral air curtain 300, the gas circularly flows, dynamic sealing is realized, leakage of the gas in the operation process of the surgical instrument is reduced, the damage of sudden change of the gas pressure to a patient is avoided, and the success rate of the surgery is improved.
In this embodiment, when the air delivery hole 130 is used to deliver air into the operation through hole 120, the fluid guide 200 may be disposed in the operation through hole 120, the fluid guide 200 is a revolving body, the fluid guide 200 may be a conical cylinder or a cylindrical cylinder, the fluid guide 200 is connected to the puncturing element 100, and the fluid guide 200 can adjust the flow direction of the air entering the operation through hole 120 from the air delivery hole 130, thereby forming the spiral air curtain 300 in the operation through hole 120. For example, the fluid guide 200 may be rotatably connected to the piercing member 100, the gas enters from the gas transmission hole 130 to drive the fluid guide 200 to rotate, and the rotation of the fluid guide 200 generates a centrifugal force to make the gas in a swirling state. In other embodiments, a spiral groove or a spiral plate may be provided on the outer circumferential surface of the drainage body 200, and the gas entering the operation through hole 120 from the gas transmission hole 130 is in a swirling state under the guidance of the spiral groove or the spiral plate, thereby forming the spiral air curtain 300.
Meanwhile, under the action of the fluid guide 200, the gas entering the operation through hole 120 from the abdominal cavity is dispersed from the middle to the periphery, the pressure of the gas is reduced, and the sealing of the spiral air curtain 300 is facilitated.
It should be noted that the gas pressure of the gas injected through the gas delivery hole 130 is set to be equal to or higher than the gas pressure of the gas discharged from the abdominal cavity. It should be appreciated that a pressure sensor may be disposed at the gas delivery port 130 to obtain the gas pressure at the gas delivery port 130 in real time, so as to compare with the gas pressure in the abdominal cavity, so that the gas pressure at the gas delivery port 130 is not less than the abdominal cavity gas pressure.
In this embodiment, the air inlet hole 110 is optionally connected to an air source, which may be a gas tank filled with carbon dioxide gas. And, an air pump is provided on the air tank, and the air pump can deliver air in the air tank to the air inlet through hole 110. In addition, the gas exhausted from the gas vent 140 enters the operation through hole 120 through the gas transmission hole 130, thereby improving the resource utilization rate and saving the cost.
In this embodiment, it should be noted that, in order to improve the cleanliness of the gas, the gas output from the gas tank is filtered by the filter unit, and the gas returned from the gas discharge hole 140 to the gas tank is filtered by the filter unit. Specifically, the air pump may be provided with two pipelines for delivering air to the air delivery hole 130 and the air inlet through hole 110, and the air outlet hole 140 and the connecting pipeline of the air tank may be provided with a plurality of filtering units, which are independent from each other and safe and reliable to use. By providing the filter unit, when smoke is generated during an operation, the smoke is discharged from the exhaust hole 140 and enters the gas tank, and the smoke is filtered after passing through the filter unit, thereby optimizing an operation environment.
Note that the gas stored in the gas tank may not be limited to carbon dioxide gas.
In addition, interstitial fluid generated during the surgical procedure can also be discharged through the vent hole 140.
According to the spiral airtight method for the operation, the medical instrument enters and exits the abdominal cavity through the centrifugal area surrounded by the spiral air curtain 300, the air pressure stability of the abdominal cavity is not affected, and therefore the operation effect is optimized. Meanwhile, the exhaust holes 140 can effectively exhaust smoke and tissue fluid generated during the operation in time, thereby optimizing the operation field of vision.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
