Description

Technical Field

[0001] The invention relates to the field of medical equipment, and in particular to a spiral airtight method for surgery. Background Art

[0002] In laparoscopic surgery, in order to provide enough space in the abdominal cavity for observation and surgery, it is necessary to use an insufflator to provide air pressure to expand the abdominal cavity. When the insufflator of the prior art is working, the intra-abdominal pressure is lower than the set value at the beginning of inflation. As more gas is introduced into the abdominal cavity, the intra-abdominal pressure gradually increases. When the intra-abdominal pressure reaches the set value, inflation stops. As the operation proceeds, abdominal leakage occurs with the movement of surgical instruments in and out, flushing the abdominal cavity and aspirating tissue fluid, and specimen removal, and the intra-abdominal pressure decreases. When it is lower than the set value, the insufflator is used again to inflate. The "inflation-pressure measurement" process of the insufflator of the prior art is called a working cycle. The entire surgical process repeats such a working cycle repeatedly, forming a periodic shock pressure. The shock pressure value varies with gas leakage during the operation. At the same time, during the operation, the electric knife in the puncture device will inevitably produce a large amount of smoke and water vapor when burning or electrocoagulating human tissue. The smoke produced by the combustion of organic matter is a strong carcinogen, which will cause unnecessary harm to the surgeon and medical staff in the operating room. In addition, when performing deep human body surgery, especially when electrocauterizing deep blood vessels and other important organs, the smoke will blur the electron microscope inside, affect the vision of medical staff, make hemostasis difficult, and even cause blind or chaotic surgery. Therefore, a smoke removal device is needed to ensure the smooth operation. The existing pneumoperitoneum machine has poor pressure stabilization effect on the abdominal cavity and poor smoke treatment effect. Summary of the invention

[0003] The purpose of the present invention is to provide a spiral airtight method for surgery, which can improve the convenience of operation, has a good abdominal pressure stabilization effect, can ensure that the surgery is carried out continuously and smoothly, and can improve the success rate of the surgery.

[0004] The embodiment of the present invention is achieved as follows:

[0005] The present invention provides a spiral airtight method for surgery, which is applicable to a puncture member having an air inlet through hole and an operation through hole which are independent of each other, the puncture member is further provided with an air delivery hole and an air exhaust hole which are both connected to the operation through hole, and a drainage body is provided in the operation through hole, comprising:

[0006] While maintaining the state of inflating the abdominal cavity through the air inlet hole, the proximal end of the operating through hole, the air delivery hole and the air exhaust hole are opened, and gas is introduced into the operating through hole through the air delivery hole. Under the guiding effect of the drainage body, the gas forms a spiral wind curtain in the operating through hole that blocks the operating through hole; under the action of the spiral wind curtain, the gas entering the operating through hole from the abdominal cavity is suppressed in the abdominal cavity.

[0007] In an optional embodiment, in the step of maintaining the state of inflating the abdominal cavity through the air inlet hole, the air pressure in the abdominal cavity is detected by using a sensor.

[0008] In an optional embodiment, in the step of detecting the air pressure in the abdominal cavity using a sensor, when the air pressure information detected by the sensor reaches a set air pressure, the gas supply hole and the gas exhaust hole are opened, so that gas is introduced into the operating through hole through the gas supply hole.

[0009] In an optional embodiment, in the step of maintaining the state of inflating the abdominal cavity through the air inlet hole, the gas in the gas tank is introduced into the air inlet hole by using an air pump.

[0010] In an optional embodiment, in the step of introducing gas into the operating through hole by using the gas delivery hole, an air pump is used to introduce the gas in the gas tank into the operating through hole through the gas delivery hole.

[0011] In an optional embodiment, in the step of the gas entering the operating through hole from the abdominal cavity and being discharged from the exhaust hole, the gas discharged from the exhaust hole enters the operating through hole through the gas delivery hole.

[0012] In an optional embodiment, before the step of inflating the abdominal cavity with air through the air inlet hole to make the air pressure in the abdominal cavity reach the set air pressure, the step further includes: filtering the gas.

[0013] In an optional embodiment, before the step of introducing gas into the operating through hole using the gas delivery hole, the step further includes: filtering the gas.

[0014] In an optional embodiment, after the step of the gas entering the operation through hole from the abdominal cavity and being discharged from the exhaust hole, the step further includes: filtering the gas.

[0015] In an optional embodiment, the gas introduced into the abdominal cavity and the operation through hole is carbon dioxide gas.

[0016] The beneficial effects of the embodiments of the present invention are:

[0017] In summary, in the spiral airtight method for surgery provided by this embodiment, during the operation, the surgical instrument is inserted from the proximal end of the operation through hole and extended from the distal end. Since a spiral air curtain is formed in the operation through hole, the surgical instrument passes through the spiral air curtain into the abdominal cavity, and the gas barrier formed by the spiral air curtain will not interfere with the movement of the surgical instrument, that is, the sealing performance of the spiral air curtain will not be weakened by the movement of the surgical instrument, and the spiral air curtain will not 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, and no gas leakage will occur during the operation of the surgical instrument. The spiral air curtain has high sealing performance;

[0018] At the same time, due to the formation of a spiral wind curtain in the operating through hole, the gas entering the operating through hole from the abdominal cavity can not only be suppressed in the abdominal cavity under the action of the spiral wind curtain, but also not easily break through the spiral wind curtain and leak from the proximal end of the operating through hole, thereby improving the abdominal cavity pressure stabilization effect. Moreover, when the gas entering the operating through hole from the abdominal cavity contacts with the spiral wind curtain, it can be driven by the spiral wind curtain to move together, so that the gas is dispersed from the middle to the surroundings, and the gas pressure entering the operating through hole from the abdominal cavity is dispersed, and the pressure will not be concentrated in the middle of the operating through hole, thereby reducing the gas pressure in the middle of the operating through hole, and the pressure required for the spiral wind curtain to seal the gas in the abdominal cavity is reduced. There is no need to set a pressurizer to pressurize the gas entering the operating through hole from the gas supply hole to form the spiral wind curtain, thereby saving energy. Moreover, when part of the gas discharged from the abdominal cavity moves with the spiral wind curtain, it participates in the formation of the spiral wind curtain, which is not only not easy to leak but also has a self-sealing effect, and has a good airtight effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] This embodiment provides a spiral airtight method for surgery, and the air pressure in the abdominal cavity is stable, which is beneficial to the surgery.

[0030] See also Figure 1 It should be noted that the spiral airtight method for surgery is applicable to the puncture member 100, which has an air inlet hole 110 and an operation hole 120 that are independent of each other. The air inlet hole 110 and the operation hole 120 extend in the same direction, and the air inlet hole 110 can be arranged around the operation hole 120. The puncture member 100 is also provided with an air delivery hole 130 and an exhaust hole 140 that are both connected to the operation hole 120. The air delivery hole 130 is located at the end of the exhaust hole 140 that is away from the operation hole 120 and is used to extend into the abdominal cavity. In other words, taking the position of the puncture member 100 in a normal use state as a reference, the position of the air delivery hole 130 is higher than the position of the exhaust hole 140.

[0031] In this embodiment, the spiral airtight method for surgery includes the following steps:

[0032] Step s100, insert the puncture member 100 into the abdominal cavity so that the distal end of the operation through hole 120 is connected to the abdominal cavity, the gas delivery hole 130 and the exhaust hole 140 are both exposed outside the abdominal cavity, and the proximal end of the operation through hole 120, the gas delivery hole 130 and the exhaust hole 140 are sealed; wherein 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 delivery hole 130 and the exhaust hole 140 are both exposed outside the abdominal cavity, and are not easily restricted by the position of the abdominal cavity, which facilitates gas delivery and exhaust operations.

[0033] Step s200, use the air inlet hole 110 to inflate the abdominal cavity so that the abdominal pressure reaches the set pressure; a pressure sensor can be set on the puncture member 100. During the inflation process, the pressure sensor detects the pressure parameters in the abdominal cavity in real time and transmits the pressure parameters to the controller. When the pressure parameters detected by the pressure sensor are within the preset pressure range in the controller, the operator is reminded that the abdominal pressure has reached the preset value, which is conducive to the next step. It should be understood that an alarm can be set to communicate with the controller. The alarm can be a sound alarm, a light alarm, or an audible and visual alarm. When the pressure parameter reaches the set value, the controller controls the alarm to sound an alarm, thereby reminding the operator, and the operation is highly safe. In addition, the pressure parameters can be transmitted to the display and displayed in real time, which is convenient for the operator to obtain, and the safety of the operation is further improved.

[0034] Step s300, while maintaining the state of inflating the abdominal cavity with the air inlet hole 110, open the proximal end of the operating through hole 120, the air delivery hole 130 and the air exhaust hole 140, and use the air delivery hole 130 to introduce gas into the operating through hole 120, and make the gas form a spiral air curtain 300 under the drainage of the drainage body 200. Among them, the spiral air curtain 300 blocks the gas escaping from the operating through hole 120, which can be understood as the spiral air curtain 300 spirally sealing the operating through hole 120, and the operating through hole 120 is used for medical devices to pass through, that is, during the operation, the medical device is inserted from the proximal end of the operating through hole 120 and extends from the distal end of the operating through hole 120, so as to enter the abdominal cavity for the corresponding surgical operation. Since the spiral air curtain 300 is formed in the operating through hole 120, the medical device passes through the spiral air curtain 300, and the spiral air curtain 300 will not affect the range of movement of the medical device, and the medical device is flexible to operate. In the prior art, a seal needs to be provided in the operating through hole 120, and the seal and the medical device are structurally sealed, that is, the medical device needs to move relative to the seal, and the sealing between the seal and the medical device also needs to be ensured during the movement. In this way, not only is the structure complicated and prone to leakage, but the design of the seal limits the range of movement of the medical device, making the medical device inconvenient to use.

[0035] During the operation, the gas entering the operation through hole 120 from the abdominal cavity is suppressed in the abdominal cavity under the guidance of the spiral air curtain 300. Since the spiral air curtain 300 is formed in the operation through hole 120, when the gas discharged from the abdominal cavity flows toward the proximal end of the operation through hole 120 (the end for inserting surgical instruments), when it reaches the position where the spiral air curtain 300 is located, the gas is blocked by the spiral air curtain 300 and will not overflow from the proximal end of the operation through hole 120, and will not cause leakage of the gas in the abdominal cavity, thereby achieving airtightness.

[0036] In the spiral airtight method for surgery provided in this embodiment, during the operation, the surgical instrument is inserted from the proximal end of the operation through hole 120 and extended from the distal end. Since the spiral air curtain 300 is formed in the operation through hole 120, the surgical instrument passes through the area surrounded by the spiral air curtain 300 and enters the abdominal cavity. The gas barrier formed by the spiral air curtain 300 will not interfere with the movement of the surgical instrument, that is, the sealing performance of the spiral air curtain 300 will not be weakened by the movement of the surgical instrument, and the spiral air curtain 300 will not 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, and no gas leakage will occur during the operation of the surgical instrument. The spiral air curtain 300 has high sealing performance;

[0037] Since 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 only not easy to break through the spiral air curtain 300 and leak from the proximal end of the operation through hole 120, but can be suppressed in the abdominal cavity, thereby improving the effect of abdominal cavity pressure stabilization. Moreover, when the gas entering the operation through hole 120 from the abdominal cavity contacts the spiral air curtain 300, it can be driven by the spiral air curtain 300 to move together, so that the gas is dispersed from the middle to the surroundings, and the gas pressure entering the operation through hole 120 from the abdominal cavity is dispersed, and there is no leakage. The pressure is now concentrated in the middle of the operating through hole 120, thereby reducing the gas pressure in the middle of the operating through hole 120, and the pressure required for the spiral air curtain 300 to seal the gas in the abdominal cavity is reduced. There is no need to set a pressurizer to pressurize the gas that enters the operating through hole 120 from the gas supply hole 130 to form the spiral air curtain 300, saving energy; and part of the gas discharged from the abdominal cavity moves with the spiral air curtain 300, and participates in the formation of the spiral air curtain 300, which is not only not easy to leak but also has a self-sealing effect, and has a good airtight effect. External gas can continue to enter the abdominal cavity from the air inlet hole 110 to ensure that the internal pressure of the abdominal cavity is stable at the set value. At the same time, the gas in the operating through hole 120 is continuously discharged from the exhaust hole 140, and the gas discharged from the exhaust hole 140 can enter the operating through hole 120 from the gas supply hole 130 to form the spiral air curtain 300. The gas is circulating, realizing dynamic sealing, reducing the leakage of gas during the operation of surgical instruments, avoiding the harm to patients caused by sudden changes in air pressure, and improving the success rate of surgery.

[0038] In this embodiment, it should be noted that when the gas delivery hole 130 is used to deliver gas to the operating through hole 120, a guide body 200 can be set in the operating through hole 120. The guide body 200 is a rotating body. The guide body 200 can be a conical cylinder or a cylindrical cylinder. The guide body 200 is connected to the puncture member 100. The guide body 200 can adjust the flow direction of the gas entering the operating through hole 120 from the gas delivery hole 130, thereby forming a spiral wind curtain 300 in the operating through hole 120. For example, the guide body 200 can be rotatably connected to the puncture member 100, and the gas enters from the gas delivery hole 130 to drive the guide body 200 to rotate, and the rotation of the guide body 200 generates centrifugal force, so that the gas is in a swirl state. In other embodiments, a spiral groove or a spiral plate can be set on the outer circumference of the guide body 200. Under the guidance of the spiral groove or the spiral plate, the gas entering the operating through hole 120 from the gas delivery hole 130 is in a swirl state, thereby forming a spiral wind curtain 300.

[0039] At the same time, under the action of the drainage body 200 , the gas entering the operation through hole 120 from the abdominal cavity is dispersed from the middle to the surroundings, and the pressure of the gas is reduced, which is beneficial to the sealing of the spiral air curtain 300 .

[0040] It should be noted that the pressure of the gas injected into the gas delivery hole 130 is set to be equal to or greater than the pressure of the gas discharged from the abdominal cavity. It should be understood that a pressure sensor can be set at the gas delivery hole 130 to obtain the air pressure at the gas delivery hole 130 in real time, which is convenient for comparison with the air pressure in the abdominal cavity, so that the air pressure at the gas delivery hole 130 is not less than the abdominal cavity air pressure.

[0041] In this embodiment, the air inlet hole 110 is optionally connected to a gas source, which may be a gas tank filled with carbon dioxide gas. In addition, an air pump is provided on the gas tank, which can deliver the gas in the gas tank to the air inlet hole 110. In addition, the gas exhausted from the exhaust hole 140 can enter the operating hole 120 from the gas delivery hole 130, thereby improving resource utilization and saving costs.

[0042] 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 returning to the gas tank from the exhaust hole 140 is filtered by the filter unit. Specifically, filter units can be respectively set on the two pipelines from the air pump to the gas delivery hole 130 and the air inlet hole 110, and a filter unit can be set on the connecting pipeline between the exhaust hole 140 and the gas tank. The multiple filter units are independently set and do not interfere with each other, and are safe and reliable to use. By setting the filter unit, when smoke is generated during the operation, the smoke is discharged from the exhaust hole 140 and enters the gas tank. The smoke is filtered after passing through the filter unit, thereby optimizing the surgical environment.

[0043] It should be noted that the gas stored in the gas tank is not limited to carbon dioxide gas.

[0044] In addition, tissue fluid generated during the operation can also be discharged from the exhaust hole 140.

[0045] In the spiral airtight method for surgery provided in this embodiment, medical instruments enter and exit the abdominal cavity through the centrifugal area surrounded by the spiral air curtain 300 without affecting the stability of the abdominal cavity air pressure, thereby optimizing the surgical effect. At the same time, the exhaust hole 140 can timely and effectively discharge the smoke and tissue fluid generated during the operation, thereby optimizing the surgical field of view.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
