Description

Technical Field

[0001] The invention relates to the technical field of laparoscope application, in particular to a single-hole laparoscope simple smoke exhaust device. Background Art

[0002] With the development of modern medicine, minimally invasive surgery has become the development direction of surgical operations. Minimally invasive surgery has the characteristics of small trauma, fast recovery, less pain, and beautiful wounds. It is the common goal and direction pursued by modern medicine. On the basis of conventional laparoscopic surgery, it has now branched out into a more sophisticated and more beautiful single-port laparoscopic technology. Single-port laparoscopic surgery uses a single puncture device at the patient's navel. All surgical instruments enter the patient's body through this device and perform surgical operations on the lesions in the abdominal cavity. After the operation, the patient's abdominal wall only has one incision, and the patient's postoperative beauty is greatly improved. This method has been favored by more and more patients and surgeons.

[0003] At present, in clinical practice, on single-port laparoscopic surgical devices, since the single-port devices currently used in clinical practice have no special smoke exhaust design, the air inlet and exhaust ports both enter from one place and are fixed, resulting in the inability of the patient's body gas to form an effective circulation, that is, the gas entering the patient's abdominal cavity and the exhaust port are both at the same position of the device. When an electric knife or an ultrasonic knife is used to cut the diseased tissue far away from the device, the smoke generated will accumulate in the diseased area and cannot be well discharged from the patient's body. The increasing amount of smoke generated in the patient's abdominal cavity during the operation will make the surgical field unclear and significantly increase the difficulty of the operation. This phenomenon increases the operation time and brings certain troubles to the surgeon, especially the beginners of single-port laparoscopy. At present, there is no single-port device surgical instrument specifically for smoke exhaust in clinical practice. Summary of the invention

[0004] The purpose of the present invention is to provide a single-port laparoscopic simple smoke exhaust device, which can effectively solve the problems existing in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a single-port laparoscopic simple smoke exhaust device, comprising an inner ring, an outer ring, a transparent inner membrane, an operating port, an outer ring, a filter diaphragm, an air suction pipe hole, a rotary switch, an exhaust interface, an air intake interface, an exhaust pipe, an operating table, and a transparent outer mold; characterized in that: the inner ring is connected to the outer ring through the transparent inner membrane; the outer ring is connected to the operating table through the transparent outer membrane; the operating port, the air suction pipe hole, and the air intake interface are connected to the operating table; the filter diaphragm, the rotary switch, and the exhaust interface are respectively located on the exhaust pipe.

[0006] Furthermore, the inner ring and the outer ring are both hard polypropylene rings, and the outer ring is oblate, and the transparent diaphragm is a transparent, elastic, rubber membrane structure.

[0007] Furthermore, the outer ring is a ring made of rubber material, and can be exactly fitted with the outer ring, the transparent outer film is a membrane structure made of rubber material, and the operating table is a plane made of hard rubber material.

[0008] Furthermore, the operating port on the operating table is an inlet and outlet for laparoscopic instruments and is provided with an anti-leakage valve therein.

[0009] Furthermore, the air inlet interface is an interface that can be connected to the laparoscopic inflation device in the operating room; the exhaust interface is an interface that can be connected to the suction device in the operating room, and the diameter of the air inlet interface is greater than the diameter of the exhaust pipe.

[0010] Furthermore, the exhaust pipe is a soft rubber tube in the air intake hole that can move forward and backward, has a filter diaphragm at the inner opening to prevent accidental inhalation and blockage, has an exhaust interface at the outer opening, and has a rotary switch on the exhaust pipe to control the exhaust pipe switch.

[0011] Furthermore, the air intake pipe hole is provided with an anti-leakage valve to prevent air leakage when the exhaust pipe moves forward and backward.

[0012] Compared with the prior art, this single-port laparoscope simple smoke exhaust device forms an effective gas circulation between the air intake interface-filter diaphragm-exhaust interface at the place where smoke is generated in the patient's body through the exhaust pipe that moves forward and backward, and can discharge the smoke generated in the surgical area out of the patient's body; during single-port surgery, since the exhaust pipe can move forward and backward at the suction pipe hole, the filter diaphragm of this single-port puncture instrument is placed at the farthest end of the surgical operation. When the electric knife and ultrasonic knife work in the patient's body, after smoke is generated, the smoke gas can pass through the filter diaphragm-exhaust interface-operating room negative pressure device at any time to effectively discharge the smoke in the patient's body out of the patient's body, and an effective smoke exhaust gas circulation of laparoscopic pneumoperitoneum machine-air intake interface-filter diaphragm-exhaust interface-operating room negative pressure device can be formed in the patient's body. The exhaust pipe can move forward and backward, and the placement position of the filter diaphragm can be flexibly adjusted to avoid affecting the surgical operation. After clinical use, this single-port laparoscope convenient smoke exhaust device can effectively solve the smoke exhaust problem in single-port surgery, is more humane, shortens the time of minimally invasive surgery, and provides a better experience for surgeons.

[0022] The benefits of the device of the present invention are: The present invention relates to a single-port laparoscopic simple smoke exhaust device, which can effectively, conveniently and quickly exhaust the smoke in the abdominal cavity out of the surgical area when performing laparoscopic single-port surgery, effectively keeping the surgical area clean and clear, and keeping the surgical field of view clear. When performing laparoscopic single-port surgery, the surgical operator uses laparoscopic forceps to place the head end of the exhaust pipe 11 with the filter diaphragm 6 at the farthest end of the surgical area, and uses energy instruments such as electric knives and ultrasonic knives to insert them into the patient's abdominal cavity through the operating port 4 for surgical operation. The smoke generated by the energy equipment can be discharged from the body at any time through the laparoscopic pneumoperitoneum machine-air inlet interface 10-filter diaphragm 6-exhaust pipe 11-exhaust interface 9-negative pressure suction device, and the caliber of the air inlet interface 10 is larger than the caliber of the exhaust pipe 11, so that the surgical area will not be reduced due to too low air pressure, and the smoke in the surgical area can be smoothly discharged from the body. During the smoke exhaust process, the rotary switch 8 on the exhaust pipe 11 can adjust the exhaust speed at any time, and the smoke exhaust can also be turned off at any time as needed. The present invention relates to a simple single-port laparoscopic smoke exhaust device, which can ensure a clear field of vision in the surgical area and significantly save the operating time of the single-port laparoscopic surgery.

[0023] The specific connection structure of the single-hole laparoscopic simple smoke exhaust device is as follows: it includes two parts, one part is a channel establishment part, including an inner ring 1, an outer ring 2 and a transparent inner membrane 3, the inner ring 1 and the outer ring 2 are hard polypropylene rings, wherein the outer ring 2 is a flat ring, and the transparent inner membrane 3 is a transparent, elastic, rubber membrane structure, the outer ring 2 can be turned over, so that the transparent inner membrane 3 is curled on the outer ring 2, thereby shortening the distance between the inner ring 1 and the outer ring 2; the other part is a working part, the outer ring 5 is an elastic, rubber ring, and it can It fits perfectly with the outer ring 2 and does not leak after being put together. The transparent outer membrane 13 is a membrane structure made of rubber material. The operating table 12 is a plane made of hard rubber material. The operating port 4 on the operating table 12 is the inlet and outlet of laparoscopic instruments. When laparoscopic surgical instruments enter and exit the device through the operating port 4, it has an anti-leakage valve (a valve-like structure, which is a common means and method for all laparoscopic instruments, which is not the technical key points and difficulties of this patent and is not described in detail in this patent application) to prevent leakage. The air inlet interface 10 is compatible with the operating room. The exhaust interface 9 is an interface connected to the laparoscopic inflation device; the exhaust interface 9 can be connected to the suction device in the operating room, and the diameter of the air inlet interface 10 is larger than the diameter of the exhaust pipe 11 (which can effectively prevent excessive exhaust and too low pneumoperitoneum pressure in the patient's surgical area). The exhaust pipe 11 is a soft rubber tube in the suction tube hole 7 that can move back and forth according to the needs of the operation and the depth of the operation. The inner opening has a filter diaphragm 6 that prevents misabsorption and blockage. This diaphragm is a sponge-like structure and is adhered to the head end of the exhaust pipe 11. While discharging smoke from the surgical area, it can effectively To prevent accidental aspiration of tissues in the abdominal cavity or the surgical area, the exhaust pipe 11 has an exhaust interface 9 at its outer mouth, which can be connected to the suction device in the operating room. The exhaust pipe 11 has a rotary switch 8 for controlling the exhaust pipe switch, and the ventilation volume of the exhaust pipe 11 can be controlled by rotating the switch 8 at different angles; the suction pipe hole 7 is provided with an anti-leakage valve (a valve-like structure, which is a commonly used means and method for all laparoscopic instruments, but is not a technical point and difficulty of this patent and will not be described in detail in this patent application), which can prevent the exhaust pipe 11 from leaking when it moves back and forth.

[0024] The specific usage method and working principle of the device are as follows: during single-port laparoscopic surgery, the surgical instrument is placed at the required surgical site (usually the navel) of the patient's abdominal wall, the abdominal wall layers are cut, and a passage from the skin to the abdominal cavity is established. Then, the inner ring 1 of the device is placed into the patient's abdominal cavity, and the outer ring 2 is left outside the patient's skin. The transparent inner membrane 3 is turned over so that the transparent inner membrane 3 is curled on the surface of the outer ring 2, and then the distance between the outer ring 2 and the inner ring 1 is tightened, and the abdominal wall layers are tightly clamped between the outer ring 2 and the inner ring 1. Then, the outer ring 5 is tightly covered on the outer ring 2, and a laparoscopic pneumoperitoneum machine is connected to the air inlet interface 10 to inflate the abdominal cavity. The operating room negative pressure suction tube is connected to the exhaust interface 9 to make an exhaust connection. At this moment, a gas circulation connection of the single-port device is established. The surgical operator uses laparoscopic surgical instrument forceps, abdominal tissue forceps and laparoscopic electrosurgical knife, laparoscopic ultrasound Surgical instruments such as acoustic knives are placed in the single-hole device through the operating port 4, and the filter membrane 6 at the front end of the exhaust pipe 11 is clamped with pliers and stretched toward the surgical area, and the filter membrane 6 is placed at the farthest end of the surgical area. At this time, a laparoscopic pneumoperitoneum machine-air inlet interface 10-filter membrane 6-exhaust pipe 11-exhaust interface 9-negative pressure suction device is formed in the patient's body and discharged from the body. Since the caliber of the air inlet interface 10 is larger than the caliber of the exhaust pipe 11, the surgical area will not be affected by the surgical operation due to the low air pressure in the surgical area during exhaust, and the surgical space will be reduced, while the smoke in the surgical area can be smoothly discharged from the body. During the exhaust process, the exhaust speed can be adjusted at any time by rotating the rotary switch 8 on the exhaust pipe 11 at different angles, and the exhaust can also be turned off at any time as needed. The exhaust pipe 11 is a hose, which can be placed at different positions in the abdominal cavity according to the needs of the operation, so as to facilitate exhaust. This device has been clinically applied, has a simple structure, is easy to operate and use, can effectively solve the exhaust problem in single-hole laparoscopic surgery, and significantly saves operation time.
