Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an abdominal surgical trocar. Background Technology

[0002] A laparoscopic trocar is used to create several small holes (0.5-1.0 cm) in the abdominal wall to establish a passage between the abdominal cavity and the outside. The trocar is inserted into a device equipped with a video recording system, a light source, and other surgical instruments. The internal condition of the abdominal cavity is transmitted to a monitor via a CCD camera. The surgeon can observe the images on the screen in real time and perform the surgical procedure. Traditionally, there are two methods for trocar insertion. One method involves first inserting a guide needle into the patient's abdominal cavity, then inflating the cavity with air to create an artificial pneumoperitoneum for observation and manipulation. Then, a medical professional inserts the trocar into the patient's body. The other method involves a medical professional directly inserting the trocar into the patient's body, followed by... The first method involves inflating the patient's abdomen with air through the inlet tube of the trocar to create an artificial pneumoperitoneum. While the second method doesn't require inserting an injection needle into the abdomen beforehand, it demands extensive experience from medical personnel. Without the inflated abdomen, the skin offers greater puncture resistance and is closer to the patient's internal organs and blood vessels. Therefore, medical personnel must be extremely focused and control the insertion force during the puncture. Furthermore, to maintain a consistent puncture angle, medical personnel may need to hold the patient's abdomen, further compressing the distance between the abdominal skin and internal organs, increasing the puncture risk and the operational stress on the medical staff. Therefore, we propose a new type of abdominal surgical trocar. Summary of the Invention

[0003] The purpose of this invention is to provide an abdominal surgical trocar to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an abdominal surgical trocar, comprising a trocar body and an arc-shaped fixing plate, wherein two arc-shaped fixing plates are provided and symmetrically distributed on both sides of the trocar body;

[0005] An arc-shaped groove is formed on one side of the arc-shaped fixing plate;

[0007] An air extraction assembly is provided on the pedal and communicates with the arc-shaped groove. The pedal is stepped on and the air extraction assembly is used to extract the gas in the arc-shaped groove so that the arc-shaped fixing plate is sucked onto the patient's abdomen.

[0008] A handle is provided on one side of the trocar body and is connected to the arc-shaped fixing plate. Pulling the handle lifts the patient's abdomen.

[0009] An auxiliary component is provided on the handle, which is used to open the two arc-shaped fixing plates to pull the patient's skin.

[0010] An arc-shaped plate, wherein two arc-shaped plates are provided and located on one side of the handle;

[0011] The linkage component, located on the handle, opens the arc-shaped fixing plate and simultaneously drives the two arc-shaped plates to align, forming a guide channel for the trocar body to guide the puncture. Unlike existing technologies, in actual use, the operator attaches the arc-shaped fixing plate to the patient's abdominal skin, then steps on the pedal and uses the suction component to draw air from the arc-shaped groove, causing the arc-shaped fixing plate to adhere to the patient's abdominal skin. During the puncture, the operator can pull the handle to move the patient's abdominal skin upwards to meet the trocar body. Simultaneously, the operator presses the pressing plate, using an auxiliary component to deflect and open the two arc-shaped fixing plates, thus stretching and flattening the patient's puncture site and exposing the puncture opening, facilitating the puncture operation. The linkage component also drives the two arc-shaped plates to close, forming a guide channel to guide the trocar body, thereby improving puncture accuracy. This increases the distance between the patient's abdominal skin and internal organs, reducing puncture risks and the operational burden on medical staff.

[0046] The suction assembly 5 is set on the pedal 4 and communicates with the arc-shaped groove 3. When the pedal 4 is stepped on, the suction assembly 5 is used to extract the gas in the arc-shaped groove 3 so that the arc-shaped fixing plate 2 is sucked onto the patient's abdomen.

[0047] Handle 6 is located on one side of the trocar body 1 and is connected to the arc-shaped fixing plate 2. Pulling handle 6 lifts the patient's abdomen.

[0048] The auxiliary component 7 is set on the handle 6. The auxiliary component 7 is used to open the two arc-shaped fixing plates 2 to pull the patient's skin.

[0049] Arc-shaped plate 8, two of which are located on one side of handle 6;

[0050] Linkage component 9 is set on handle 6. When the arc-shaped fixing plate 2 is opened, the linkage component 9 drives the two arc plates 8 to align and form a guide channel for the puncture device body 1 to guide the puncture.

[0051] The operator attaches the arc-shaped fixation plate 2 to the patient's abdominal skin, then steps on the pedal 4 and uses the suction component 5 to extract air from the arc-shaped groove 3, causing the arc-shaped fixation plate 2 to adhere to the patient's abdominal skin. During the puncture procedure, the operator can pull the handle 6 to move the patient's abdominal skin upward to meet the puncture device body 1. Simultaneously, the operator presses the pressing plate 73, using the auxiliary component 7 to deflect and open the two arc-shaped fixation plates 2, thereby pulling and flattening the patient's puncture site and exposing the puncture site, facilitating the puncture operation. At the same time, the linkage component 9 drives the two arc-shaped plates 8 to close, forming a guide channel to guide the puncture device body 1, thereby improving the accuracy of the puncture.

One end of the piston 55 is fixedly connected to a push rod 56. The end of the push rod 56 slides through the injection container 53 and is connected to the pedal 4. Stepping on the pedal 4 moves the push rod 56, thereby moving the piston 55 and extracting the gas in the arc-shaped groove 3.

[0053] A spring 57 is fixedly connected between the pedal 4 and the mounting plate 51. When the pedal 4 is stepped on, the spring 57 is compressed to provide self-recovery capability.

[0054] The push rod 56 is fixedly connected to a sliding protrusion 58, and a rectangular plate 59 is fixedly connected to one side of the pedal 4. A sliding groove 61 is provided on the rectangular plate 59. One end of the sliding protrusion 58 is located in the sliding groove 61 and is slidably connected to its inner wall to guide and limit the movement of the sliding protrusion 58.

[0055] The curved fixing plate 2 has a rubber material design on the contact surface with the human body, which improves comfort and increases airtightness.

The shaft 71 is rotatably connected to the lifting bearing of the handle 6, and a rotating cylinder 72 is fixedly connected to the shaft 71. A pressing plate 73 is slidably connected to one side of the handle 6. A spring 74 is fixedly connected between the pressing plate 73 and the handle 6. A synchronization component 75 is provided between the pressing plate 73 and the handle 6. The pressing plate 73 moves relative to the handle 6 and the rotating cylinder 72 is rotated by the synchronization component 75, so that the arc-shaped fixed plate 2 deflects. At the same time, the spring 74 is compressed under force to provide its self-recovery capability.

[0058] The synchronization component 75 includes a round protrusion 76 fixedly connected to the end of the pressing plate 73, and a second sliding groove 77 is provided on the handle 6. A threaded groove 78 is provided on the rotating cylinder 72. One end of the round protrusion 76 slides through the second sliding groove 77 and is located in the threaded groove 78 and is slidably connected to its inner wall. Moving the pressing plate 73 causes the round protrusion 76 to move along the second sliding groove 77, thereby using the round protrusion 76 to push the threaded groove 78, thereby causing the rotating cylinder 72 to deflect, thereby causing the L-shaped support rod 62 to deflect, thereby causing the arc-shaped fixing plate 2 to deflect.

[0059] A rectangular protrusion 79 is fixedly connected to the handle 6, and a sliding groove 81 is provided on the pressing plate 73. One end of the rectangular protrusion 79 is located in the sliding groove 81 and is slidably connected to its inner wall to guide and limit the pressing plate 73.

[0060] A tripod 82 is fixedly connected to one side of the handle 6, and both curved plates 8 are connected to the tripod 82;

[0061] The linkage component 9 includes a shaft 91 fixedly connected to one side of the arc plate 8. A gear plate 92 is fixedly connected to the shaft 91, and a rectangular slide plate 93 is slidably connected to the tripod 82. Both sides of the rectangular slide plate 93 are evenly spaced with multiple toothed grooves 94 that mesh with the gear plate 92. Pulling the rectangular slide plate 93 causes the gear plate 92 to rotate, thereby causing the shaft 91 to rotate, which in turn causes the two arc plates 8 to deflect and align. Conversely, opening the arc plate 8 allows the main body of the device to be removed so that it can be used in conjunction with the next puncture device main body 1.

[0062] A sliding rod 95 is fixedly connected to one end of a rectangular sliding plate 93, and one end of the sliding rod 95 slides through the tripod 82. A spring 96 is sleeved on the sliding rod 95. The two ends of the spring 96 are fixedly connected to the tripod 82 and the rectangular sliding plate 93 respectively. Pulling the sliding rod 95 causes the rectangular sliding plate 93 to move, and at the same time, the spring 96 contracts under force to provide its self-recovery ability.

[0063] A transmission assembly 97 is provided between the pressing plate 73 and the slide bar 95. Moving the pressing plate 73 will drive the slide bar 95 to move using the transmission assembly 97.

[0064] The transmission assembly 97 includes a mounting block 98 fixedly connected to one end of the slide bar 95, and a mounting block 98 is also fixedly connected to one side of the pressing plate 73.

The two ends of the connecting rod 99 are rotatably connected to the two mounting blocks 98 through a rotating shaft, and the two ends of the connecting rod 99 rotate relative to the two mounting blocks 98. Moving the pressing plate 73 drives the connecting rod 99 to move, thereby driving the slide bar 95 to move.

[0065] During the normal operation of the abdominal trocar, the arc-shaped fixing plate 2 is attached to the patient's abdominal skin. Then, the foot pedal 4 moves the push rod 56, which in turn moves the piston 55, drawing gas from the arc-shaped groove 3. This causes the arc-shaped fixing plate 2 to adhere to the patient's abdominal skin. During the puncture procedure, the operator can pull the handle 6 to move the patient's abdominal skin upwards to meet the trocar body 1. Simultaneously, the operator presses the pressing plate 73, which uses the round protrusion 76 to actuate the threaded groove 78, causing the rotating cylinder 72 to deflect, which in turn causes the L-shaped support rod 62 to deflect. The curved fixing plate 2 is deflected and opened, thereby pulling and flattening the skin at the puncture site and exposing the puncture site, making it easier for the operator to perform the puncture. At the same time, the connecting rod 99 moves, which in turn moves the sliding rod 95, which pulls the rectangular sliding plate 93 to rotate the gear plate 92, which in turn rotates the shaft 91. This causes the two curved plates 8 to deflect and close, forming a guide channel to guide the puncture device body 1, thereby improving the accuracy of the puncture, increasing the distance between the patient's abdominal skin and internal organs, reducing the puncture risk, and also reducing the operational pressure on medical staff.

Conversely, opening the arc plate 8 allows the main body of the device to be removed so that it can be used in conjunction with the next puncture device main body 1.

[0086] A sliding rod 95 is fixedly connected to one end of a rectangular sliding plate 93, and one end of the sliding rod 95 slides through the tripod 82.

This causes the arc-shaped fixation plate 2 to adhere to the patient's abdominal skin. During the puncture procedure, the operator can pull the handle 6 to move the patient's abdominal skin upwards to meet the trocar body 1. Simultaneously, the operator presses the pressing plate 73, which in turn uses the round protrusion 76 to push the threaded groove 78, causing the rotating cylinder 72 to deflect. This, in turn, causes the L-shaped support rod 62 to deflect, opening the arc-shaped fixation plate 2 and thus pulling and flattening the patient's abdomen. The purpose of puncturing the skin is to expose the puncture site, thereby facilitating the puncture operation. Simultaneously, moving the pressing plate 73 squeezes the air bag 104, causing gas to fill the injection container 101, which in turn moves the piston 102, which in turn moves the push rod 103, which in turn moves the slide rod 95, which in turn pulls the rectangular slide plate 93, causing the gear plate 92 to rotate, which in turn rotates the shaft 91, which in turn causes the two arc plates 8 to deflect and close, forming a guide channel to guide the puncture device body 1, thereby improving the accuracy of puncture, increasing the distance between the patient's abdominal skin and internal organs, and thus reducing the puncture risk, while also reducing the operational pressure on medical staff.
