Abstract

The port comprises an inner base, an outer base, an inner diaphragm, an instrument opening, an outer sleeve base, a traction line, a ventilation side hole, an outer diaphragm, an exhaust pipe, an inner cylinder spring, an inner cylinder, an inner cylinder shaft, an exhaust port, a working plate, an air inlet, an exhaust pipe hole and an exhaust cylinder. The instrument has the biggest advantage that smoke in an operation area can be easily removed; when a single-port laparoscopic surgery operation is carried out, smoke generated when energy instruments such as an electric hook and an ultrasonic knife in an abdominal cavity cut tissue can form convection current with an air inlet through an exhaust port of the instrument, smoke gas generated by the electric hook can be easily and accurately exhausted out of a surgical area, and it is guaranteed that the surgical field of the surgical area is clear and distinguishable; and the single-hole operation time is obviously saved. Through clinical trials, the instrument set can shorten the time of single-hole minimally invasive surgery, and the experience of surgeons is better.

Description

Technical Field

[0001] The invention relates to the technical field of laparoscope application, in particular to a port for convenient smoke exhaust for a single-port laparoscope. 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, a more sophisticated and more beautiful single-port laparoscopic technology has now been branched out. Single-port laparoscopic surgery uses a single Port 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 has only one incision, and the patient's postoperative beauty is greatly improved, which has been favored by more and more patients and surgeons.

[0003] However, in the single-port laparoscopic surgery port, since the single-port port currently used in clinical practice has no special smoke exhaust design, the air inlet and exhaust port both enter from one place, 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 at the same position. When an electric knife or an ultrasonic knife is used to cut the diseased tissue far away from the port, the smoke is gathered 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. In addition, there is currently no single-port surgical instrument specifically for smoke exhaust in clinical practice. Inventive content

[0004] The purpose of the present invention is to provide a single-port laparoscope port that is convenient for smoke exhaust, 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 laparoscope port for convenient smoke exhaust, comprising an inner base, an outer base, an inner diaphragm, an instrument port, an outer sleeve seat, a pull wire, a ventilated side hole, an outer diaphragm, an exhaust pipe, an inner cylinder spring, an inner cylinder, an inner cylinder shaft, an exhaust port, a working plate, an air inlet, an exhaust pipe hole, and an exhaust tube; characterized in that: the inner base is connected to the outer base through the inner diaphragm; the outer sleeve seat is connected to the working plate through the outer diaphragm; the pull wire is connected to the exhaust port through the exhaust pipe; the ventilated side hole is connected to the exhaust pipe; the inner cylinder spring is a spring located inside the inner cylinder, one end of which is connected to the working plate, and the other end is connected to the inner cylinder; the instrument port, the air inlet and the exhaust tube are fixedly connected to the working plate; the inner cylinder spring is located inside the inner cylinder, one end of which is fixedly connected to the inner cylinder, and the other end is connected to the exhaust tube.

[0006] Furthermore, the inner base and the outer base are hard polypropylene bases, and the inner base and the outer base are connected by an inner diaphragm made of a transparent, elastic rubber material.

[0007] Furthermore, the outer sleeve seat is an elastic, rubber-made slot base that can be tightly buckled with the outer base, the outer diaphragm is a transparent diaphragm made of rubber, and the working plate is a thick rubber-made flat plate.

[0008] Furthermore, a thin pulling wire is fixed to one end of the exhaust pipe, and at the same time, an anti-clogging ventilation side hole is designed; the exhaust pipe passes through the exhaust pipe hole on the working plate, is wound around the inner tube, and the other end is fixed to the inner tube.

[0009] Furthermore, the inner cylinder is a cylinder enclosed in the exhaust cylinder and rotatable around the inner cylinder axis. An inner cylinder spring is arranged in the inner cylinder, and the exhaust pipe can be wound around the inner cylinder.

[0010] Furthermore, the instrument port is a channel through which laparoscopic instruments can pass, and has an anti-leakage valve structure inside.

[0011] Furthermore, the air inlet can be connected to a common pneumoperitoneum machine in an operating room; and the air outlet can be connected to a common exhaust strap in an operating room.

[0012] Furthermore, the inner cylinder spring is located inside the inner cylinder, one end of the inner cylinder spring is fixed inside the inner cylinder, and the other end is fixed on the exhaust pipe, and can maintain the rotational force of the inner cylinder.

[0013] Compared with the prior art, this single-port laparoscope has a convenient smoke exhaust port, which forms an effective gas circulation at the place where smoke is generated in the patient's body through a retractable exhaust pipe, and can exhaust the smoke generated in the surgical area out of the patient's body; the traction line of the single-port puncture instrument can be placed on the head end of the tissue forceps used in the operation, and the forceps can be flexibly moved in the surgical area without changing the existing operating habits of the operator. The laparoscopic surgical forceps buckle is used in the abdominal cavity, the traction line is hung, and the exhaust pipe is pulled into the patient's abdominal cavity to the surgical area. When the electric knife or ultrasonic knife works in the patient's body, smoke is generated, By adjusting the ventilation side hole connected to the traction wire carried by the forceps, the smoke in the patient's body can be effectively discharged from the patient's body through the ventilation side hole-exhaust pipe-exhaust tube-exhaust port, and an effective gas circulation through the air inlet-ventilation side hole-exhaust pipe-exhaust tube-exhaust port can be formed in the patient's body. The patient's internal laparoscopic forceps can clamp the traction wire and adjust the position of the ventilation side hole at any time to make it more convenient to discharge the smoke. After the operation is completed, the exhaust pipe can be stored in an orderly manner through the internal winding device of the exhaust tube-inner tube under the action of the spring inertia in the inner tube to prevent the exhaust pipe from being messy and affecting the operation. After clinical use, this single-port laparoscope with convenient smoke exhaust port can effectively solve the smoke exhaust problem in single-port surgery, which is more humane, shortens the time of minimally invasive surgery, and provides a better experience for surgeons.

[0024] The benefits of the device of the present invention are: The present invention is a single-port laparoscope with a convenient smoke exhaust port. When performing a single-port laparoscopic surgery, the smoke in the abdominal cavity can be effectively, accurately and quickly exhausted out of the surgical area, effectively keeping the surgical area clean and clear, and keeping the surgical field of view clear. When performing a single-port laparoscopic surgery, the surgical operator inserts the laparoscopic surgical forceps through the instrument port, opens the jaws, hangs the traction line 6, and extends it into the patient's abdominal cavity. Then, another laparoscopic electric knife is taken through another instrument port 4 to penetrate into the abdominal cavity to perform tissue cutting. The smoke gas in the patient's body can be discharged from the patient through the ventilated side hole 7-exhaust pipe 9-exhaust port 13-negative pressure suction device in the operating room. At the same time, under the elastic inertia of the inner cylinder spring 10, the exhaust pipe 9 can be conveniently stored on the inner cylinder 10 inside the exhaust cylinder 17, ensuring a clear surgical field of view, preventing the exhaust pipe 9 from affecting the operator's operation in the surgical area, and significantly saving the single-port laparoscopic surgery operation time.

[0025] The specific connection structure of the type of the present invention is as follows: it includes two parts, one part is the channel establishment part placed in the patient's abdominal cavity, including an inner base 1, an outer base 2 and an inner diaphragm 3, the inner base 1 and the outer base 2 are both rings made of hard polypropylene, the inner diaphragm 3 is a transparent, elastic inner diaphragm 3 made of rubber, and the inner diaphragm 3 is connected and fixed to the inner base 1 and the outer base 2. The outer base 2 can be flipped over to allow the inner diaphragm 3 to roll on the outer base 2, thereby shortening the distance between the outer base 2 and the inner base 1; the outer sleeve 5 is an elastic, rubber-made card slot base that can be tightly snapped together with the outer base 2, the outer diaphragm 8 is a transparent, elastic rubber-made outer diaphragm 8, one end of the outer diaphragm 8 is tightly connected to the outer sleeve 5, and the other end is tightly connected to the working plate 14; the working plate 14 is provided with an instrument port 4, an air inlet 15, and an exhaust pipe 17; the exhaust pipe 17 is fixed on the working plate 14, and the exhaust pipe 17 has a structure that can surround the inner cylinder axis 12 The inner cylinder 11 rotates, and an inner cylinder spring 10 is arranged inside the inner cylinder 11. One end of the inner cylinder spring 10 is fixed inside the inner cylinder 11, and the other end is fixed on the exhaust cylinder 17, and the rotation force of the inner cylinder can be maintained. In a natural state, under the inertia of the inner cylinder spring 10, the exhaust pipe 9 can be rotated and contracted on the surface of the inner cylinder 11 in an orderly manner, and the exhaust pipe 9 can enter the interior of the device through the exhaust pipe hole 16. The head end of the exhaust pipe 9 is provided with a pulling line 6 and a ventilation side hole 7; the air inlet 15 can be connected to a common pneumoperitoneum machine in an operating room; the exhaust port 13 can be connected to a common exhaust leather strip in an operating room.

[0026] The specific usage method and working principle of this instrument are as follows: during laparoscopic single-port surgery, at the part of the patient's abdominal wall that requires surgery (usually the navel), the various layers of the abdominal wall are cut open, and after a passage from the skin to the abdominal cavity is established, the base 1 of this instrument is placed into the patient's abdominal cavity, with the outer base 2 remaining on the outside of the patient's skin. The outer base 2 is flipped over so that the inner diaphragm 3 is curled on the surface of the outer base 2, thereby tightening the distance between the outer base 2 and the inner base 1, and then the outer sleeve 5 is tightly covered on the outer base 2, and a laparoscopic pneumoperitoneum machine is used to connect the air inlet 15 to inflate the abdominal cavity, and an operating room negative pressure suction tube is used to connect the exhaust port 13 to make an exhaust connection. At this moment, a gas circulation connection of the port of the single-port instrument is established; the surgical operator uses a laparoscopic surgical instrument forceps to insert it into the single-port port through the instrument port 4, opens the jaws, observes the transparent outer diaphragm 8, puts the traction wire 6 into the jaws, and then pulls the exhaust tube 9 into the abdominal cavity and wraps it around the inner tube 11. The exhaust pipe 9 can pass through the exhaust pipe hole 16. As the laparoscopic forceps are pulled out and enter the patient's abdominal cavity, inside the exhaust pipe 17, after the exhaust pipe 9 is pulled out, the inner cylinder spring 10 inside the inner cylinder 11 will increase in tension as the exhaust pipe 9 is extended. At this time, a gas circulation flow of the air inlet 15-ventilation side hole 7-exhaust pipe 9-exhaust port 13 is formed in the patient's body. The surgical operator uses a laparoscopic electric knife to insert it into the patient's abdominal cavity through the instrument port 4 to perform electrocoagulation and cutting operations. During laparoscopic surgery, the smoke gas can be sucked out of the body wherever the operating forceps are. At this time, the smoke gas generated by the electric knife can be conveniently discharged from the surgical area to ensure that the field of vision of the surgical area is clear and discernible; when the operation is completed, the laparoscopic surgical forceps are withdrawn, the exhaust pipe 9 is in a relaxed state, and the exhaust pipe 9 rotates under the elastic tension of the inner cylinder spring 10 of the inner cylinder 11, and the exhaust pipe 9 can be rotated, coiled, and fixed on the inner cylinder 11 to store the exhaust pipe 9. Through clinical application, this device can effectively solve the problem of smoke exhaust in single-port surgery and significantly save operation time.
