Description

Technical Field

[0001] The present invention relates to the field of medical technology, and particularly to an intraperitoneal support device for neonatal laparoscopic surgery.

Background Art

[0002] Minimally invasive treatment technology has developed rapidly in recent years and has gradually been recognized by more and more doctors for its characteristics of small surgeries and minor traumas, which is an inevitable trend in the development of future surgical methods.

[0003] Currently, surgeries involving the abdominal cavity such as general surgery are gradually changing from open surgeries to minimally invasive intracavitary surgeries. More and more doctors have received laparoscopic technology training, and their surgical operations are becoming more and more proficient, playing an important role in the popularization and promotion in hospitals at all levels. On the other hand, it has also further promoted the development of laparoscopes and supporting surgical instruments.

[0004] However, the traditional intraperitoneal support device has poor stability and exerts a large outward expanding force on the abdominal cavity opening during abdominal surgery, which is likely to cause tearing at the opening.

[0005] Moreover, the ordinary intraperitoneal support device relies on manual fixation by doctors. However, the skin of newborns is delicate and the abdominal area is small, making it more likely to be torn due to excessive force.

[0006] Therefore, a novel intraperitoneal support device for neonatal laparoscopic surgery is proposed, which can improve the support stability while avoiding excessive clamping force between the support device and the opening, thereby enhancing the safety of use.

The operation tube 1 and the receiving cylinder 2 are connected by clamping at the lower part to fix the operation tube 1 in the receiving cylinder 2. A top support assembly 3 that is slidably connected to the operation tube 1 up and down is provided above the operation tube 1. The top support assembly 3 is clamped at the abdominal opening. A spreading assembly 4 that is also slidably connected to the operation tube 1 up and down is provided below the top support assembly 3. The spreading assembly 4 is used to form an upward supporting force on the top support assembly 3 to fix the top support assembly 3 at the abdominal opening. The top support assembly 3 is an umbrella-shaped boss member with a hollow interior, and the spreading assembly 4 is an umbrella-shaped boss member with a hollow interior. The diameter of the upper end of the top support assembly 3 is smaller than that of the lower end, and the diameter of the upper end of the spreading assembly 4 is larger than that of the lower end. When the top support assembly 3 is spread, the two wings can expand the abdominal cavity space and push up the abdominal skin to form a good surgical operation field of view, while maintaining surgical sterility and meeting the requirements of surgical sterility.

[0047] A sliding block 5 is provided below the spreading assembly 4. The source of the moving power of the sliding block 5 can be electric power or manual pulling. The sliding block 5 spreads the top support assembly 3 at an appropriate angle by moving the spreading assembly 4 up and down according to the size of the abdominal cavity hole to achieve stable support;

[0048] In this embodiment, the top support assembly 3 and the spreading assembly 4 are automatically opened or closed by electric power, saving manpower and having accurate opening angles. While achieving stable connection, they will not form a tearing force on the abdominal skin. It also includes a first angle detection unit 6 that can detect the first angle required for the top support assembly 3 to open relative to the diameter of the abdominal cavity hole and output a first signal;

[0049] A second angle detection unit 7 that can detect the second angle at which the spreading assembly 4 opens relative to the first angle at which the top support assembly 3 opens and output a second signal;

[0050] The data processing unit is electrically connected to the first angle detection unit 6 and the second angle detection unit 7. The data processing unit is configured to process the first signal and the second signal, output the final result of the angle of the supporting assembly 3 and display it.

[0053] The second angle detection unit 7 includes: a second magnetic block 10, which is arranged on the outside of the lower end of the bottom of the expansion component 4 and moves up and down with the expansion component 4; a second angle sensor 11, which is arranged on the outer wall of the operating tube 1 and is located between the expansion component 4 and the bottom of the storage column 2 to prevent the second angle sensor 11 from being hit by the expansion component 4 moving up and down, thereby extending its service life, and is arranged opposite to the second magnetic block 10.

The first hem 12 is opened or closed to adjust the size of the first angle, and the second hem 14 is opened or closed to adjust the size of the second angle. The second hem 14 and the first hem 12 are arranged relative to each other, which is conducive to the second hem 14 forming a stable support for the first hem 12.

[0055] The diameter of the second top surface 15 is smaller than that of the first top surface 13, which helps the expansion component 4 to enter the interior of the top support component 3 and form a conflict with the top support component 3. The diameter of the first top surface 13 is smaller than the diameter of the storage column 2, which is convenient for recovering the top support component 3 as a whole and placing it in the storage column 2 after the operation. The expansion component 4 controls the second lower hem 14 to open to the second angle, forming a conflict with the top support component 3 to control the top support component 3 to open to the first angle.

[0056] The size of the first angle can be changed by changing the distance between the spreading component 4 and the supporting component 3 and / or the radius of the second lower skirt 14 .

[0057] Calculating the first angle according to the distance between the spreading component 4 and the supporting component 3, the radius of the second hem 14, and the size of the abdominal cavity hole includes: calculating the first angle by the following formula:

[0058] Among them, α1 is the first angle, R2 is the radius of the second hem 14, R3 is the radius of the abdominal cavity hole, H is the distance between the expansion component 4 and the top support component 3, and e is a natural constant.

[0059] Embodiment 2:

[0060] The difference between this embodiment and the first embodiment is that the first angle is A1 and the second angle is A2;

[0061] Q=N1 / N2, N2 is the vertical height between the second hem 14 and the second top surface 15, and N1 is a natural constant;

[0062] A1=A2*Q+A', A' is a calibration value, and the expansion assembly 4 is calibrated before the measurement starts, so that A'=0.

[0063] For example, when A2 = 30°, A' = 0, N2 = 10, N1 = 1, Q = 1 / 10, A1 = 30*0.1 = 3°;

[0064] When A2=60°, A'=0, N2=5, N1=1, Q=1 / 5, A1=60*0.2=30°.

[0065] In this way, by coordinating the first angle and the second angle and combining the measurement algorithm, accurate angle measurement can be achieved.

[0066] It also includes a fixing member 16 and a fixing rope 17. The fixing member 16 is arranged between the sliding block 5 and the spreading assembly 4, and the fixing rope 17 is fixedly connected to the fixing member 16, so as to facilitate fixing the supporting assembly 3 and the spreading assembly 4.
