TECHNICAL FIELD

[0001] The utility model relates to medical appliance field, concretely is a magnetic anchoring auxiliary blocking rod under laparoscope. BACKGROUND

[0002] With the continuous development of laparoscopic surgery technology, single-hole laparoscopic surgery has been widely used in surgical operations due to its small trauma, fast recovery and other advantages. However, single-hole surgery has difficulties in surgical field exposure, especially in obtaining the visual field of the stomach and other deep organs. Traditional exposure methods usually rely on mechanical traction and manual operation to pull up the liver or other tissues to expand the surgical field. However, as the complexity of the operation increases, the existing methods are difficult to meet the needs in terms of operation space, instrument types and exposure effect.

[0003] Magnetic anchoring technology, as an emerging auxiliary technology, has unique advantages in improving surgical field.

[0032] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0033] Example 1

[0034] like Figs. 1-3 As shown, a magnetic anchoring auxiliary stop for laparoscopy includes an outer magnet 1 located outside the abdominal cavity and an inner magnet 2 located inside the abdominal cavity. The inner magnet 2 can be attracted to the outer magnet 1. A telescopic stop 3 for blocking organs and tissues is fixedly provided on the side of the inner magnet 2 away from the outer magnet 1. The telescopic end of the telescopic stop 3 is provided with a fixing part 6 for establishing a connection with the tissues inside the abdominal cavity.

[0035] The beneficial effects of this embodiment are: one end of the telescopic stop bar 3 is fixed on the abdominal cavity tissue in the non-surgical area, and the other end is moved externally by the external magnet 1. The telescopic stop bar 3 blocks and pushes the organs and tissues to adjust their position, thus exposing the surgical field of vision and making the operation simple; at the same time, the telescopic stop bar 3 passively extends and retracts to adapt to different distances of abdominal cavity space, making it more flexible.

[0036] In this embodiment, a puncture hole is opened before abdominal surgery. The inner magnet 2 and the telescopic stop bar 3 are first placed into the patient's abdominal cavity. The fixing part 6 is fixedly connected to the abdominal wall, peritoneum, or a certain organ or tissue that does not need to be moved. Then, the telescopic stop bar 3 is positioned, and the outer magnet 1 is attracted to the inner magnet 2 at the other end from outside the abdomen. The operator moves the outer magnet 1 from the outside, causing the inner magnet 2 to move accordingly. The organ that needs to be moved is opened by the rod of the telescopic stop bar 3, exposing the surgical field. The telescopic stop bar 3 extends and retracts automatically according to the increase or decrease of the moving distance, adapting to different distances of abdominal space.

[0037] During the operation, the surgical instruments are also inserted through the puncture hole, eliminating the need to create an additional operating hole for the telescopic stop bar 3 in the patient's abdominal wall, thus reducing patient injury.

[0038] Furthermore, existing tissue hooks require direct attachment to the organ or tissue that needs to be moved, followed by external magnetic traction. If this area is far from the external magnet outside the abdominal wall, it is difficult to guarantee the magnetic strength, making traction inconvenient. In this solution, one end of the telescopic stop bar 3 is connected to the non-surgical area of ​​the abdominal wall or organ that does not need to be moved, while the other end is magnetically connected to the inside of the abdominal wall. The connection point between the two ends experiences less force, resulting in less harm to the patient. The telescopic stop bar 3 allows for the movement of organs or tissues obstructing the field of vision, offering a wider range of adjustment and greater flexibility.

[0039] In addition, two or more telescopic bars 3 can be provided on the inner magnet 2. The fixing part 6 of the two telescopic bars 3 is fixed to different abdominal cavity positions respectively, which increases the range that the inner magnet 2 can be moved to ensure the effect of blocking organs and tissues and exposing the field of vision.

[0043] In this embodiment, the first protective shell 4 is open to the side facing the inner magnet 2, and the second protective shell 5 is open to the side facing the outer magnet 1. The two reduce the obstruction between each other and better release the magnetic force.

[0044] Based on this embodiment, the outer magnet 1 is fixed inside the first protective shell 4 by a retaining ring, and can be removed from the open side of the first protective shell 4 for replacement and maintenance;

[0045] The inner magnet 2 is fixed inside the second protective shell 5 by a retaining ring, and can be removed from the open side of the second protective shell 5 for replacement and maintenance.

[0052] Preferably, the fixing part 6 is a connecting hook.
