Description

Technical Field

[0001] The utility model relates to daily necessities for human beings, in particular to medical instruments, in particular to a retractable laparoscopic surgical access cleaning device. Background Art

[0002] Laparoscopic surgery has a long history, spanning 122 years. Laparoscopic surgery has become a common method of modern surgery due to its advantages such as minimal trauma and rapid recovery. Laparoscopic surgery places extremely high demands on surgeons, assistants, instruments, and equipment, and surgical safety is extremely important. During surgery, the establishment of a laparoscopic surgical access is a key step, directly affecting the surgical field of view, operating space, and safety. The surgical access creation process mainly includes two stages: establishing pneumoperitoneum and puncture and cannulation (Trocar). First, CO2 gas is injected into the abdominal cavity to separate the abdominal wall from the internal organs and establish carbon dioxide pneumoperitoneum. After pneumoperitoneum is established, a puncture cannula is inserted to form a surgical access for instrument operation. Because the surgical pathway contains excessive fat, bleeding, and smoke generated by electrosurgery, which affect the surgical field of view and the progress of the operation, the traditional cleaning method uses gauze to clean the surgical pathway. However, the gauze can only clean the shallower parts of the surgical pathway and cannot clean it thoroughly. The deeper parts inside cannot be cleaned. The gauze may also damage the anti-leak valve in the surgical pathway, causing air leakage, unstable pneumoperitoneum pressure, and unclear surgical field of view. Summary of the Invention

[0016] The following is a further description of the present invention in conjunction with an embodiment. However, the present invention is not limited to the embodiment. All similar structures and similar variations of the present invention should be included in the scope of protection of the present invention. The use of directions such as up, down, front, back, left, and right in the present invention is only for the convenience of clear description and does not limit the technical solution of the present invention.

[0017] like Figure 1-Figure 4As shown, a retractable laparoscopic surgical access cleaning device of the present invention comprises a cylinder 1, the front end and rear end of the cylinder 1 are respectively provided with an opening and a closed end, a spring 2 and a movable seat 3 are provided in the cylinder 1, the rear end of the spring 2 is connected to the closed end, and the front end of the spring 2 is connected to the movable seat 3, and the spring 2 biases the movable seat 3 toward one side of the closed end, and the front side of the movable seat 3 is connected with a cleaning rod 4, which extends axially forward along the cylinder 1, and a radial limiting rod 5 is fixedly provided on the side of the movable seat 3, and a slide groove 6 is axially provided in the side wall of the cylinder 1, and the two ends of the slide groove 6 are respectively provided with a first card groove 7 and a second card groove 8 in the circumferential direction, and the limiting rod 5 can be moved to the slide groove 6, the first card groove 7 or the second card groove 8, and a driving sleeve 9 is provided on the outer periphery of the cylinder 1, which is fixedly connected to the movable seat 3.

[0018] Furthermore, it also includes a funnel-shaped base 10, and the cleaning rod 4 cooperates with the through hole of the funnel-shaped base 10.

[0019] Furthermore, the cleaning rod 4 is cylindrical, and a round head 11 is provided at the front end of the cleaning rod 4.

[0021] The working principle of this embodiment is as follows:

[0022] When the cleaning rod 4 is not in use, it is retracted in the cylinder 1, the spring 2 is in a stress-free state, and the limiting rod 5 is located in the first slot 7. During laparoscopic surgery, when the surgical access needs to be cleaned, the laparoscope is first taken out of the surgical access, the driving sleeve 9 of the cleaning device is rotated, and the driving sleeve 9 is pushed forward to overcome the force of the spring 2, and the driving sleeve 9 is rotated again to drive the movable seat 3 to move forward, the cleaning rod 4 extends forward from the cylinder 1, and the limiting rod 5 passes through the slide 6 from the first slot 7 to the second slot 8, and then the funnel-shaped base 10 is docked with the surgical access, so that the cleaning rod 4 extends into the surgical access for cleaning. After cleaning, the cleaning rod 4 is removed, the driving sleeve 9 is rotated, and the limiting rod 5 enters the slide 6 from the second slot 6. The spring 2 drives the movable seat 3 and the cleaning rod 4 to retract into the cylinder 1 by relying on the rebound force, and then the driving sleeve 9 is rotated to make the limiting rod 5 enter the first slot 6.

[0023] Advantages of this utility model:

[0024] 1. The cleaning rod 4 can be extended into a deeper position inside the surgical access for cleaning, which can quickly clean the blood, fat and body fluids in the surgical access, making the surgical field of view clearer.

[0025] 2. The cylindrical cleaning rod 4 and the round head 11 at the front end of the cleaning rod 4 are not likely to cause damage to the anti-leak valve in the surgical access, and the cleaning rod 4 is not easily damaged, thus preventing foreign matter from being left in the body cavity.

[0026] 3. The funnel-shaped base 10 is tightly connected to the surgical access to ensure stable pneumoperitoneum pressure.

[0027] 4. The cleaning rod 4 can automatically rebound by relying on the spring 2, which facilitates the retraction of the cleaning rod 4. The cleaning device can be operated with one hand, and the other hand can hold the laparoscope, thereby improving the efficiency of the operation.
