[0020] In actual application, the existing laparoscopic trocar limiter adjusts the depth of the trocar in the abdominal cavity by manually rotating the positioning screw and cooperating with the positioning hole. However, the operation process of rotating the positioning screw is cumbersome and time-consuming, which affects the efficiency of the operation. In addition, it is difficult for the doctor's hand to rotate such a small positioning screw. Therefore, it is not practical and the cost is high.

[0021] Depend on Figure 1 The utility model provides a laparoscopic trocar limiter.

[0022] Specifically, by Figure 1It includes a trocar body 1, the outer part of the rod of the trocar body 1 is sleeved with an elastic ring 2, the elastic ring 2 is smaller than the head of the trocar body 1, and a through hole is integrally formed inside the elastic ring 2, and the inner wall of the through hole fits with the outer wall of the rod of the trocar body 1.

[0023] In the utility model, the elastic collar 2 is first sleeved on the outside of the trocar body 1, and the elasticity of the elastic collar 2 is set and utilized to make it difficult for the elastic collar 2 to move on the rod of the trocar body 1 without human power, and then the elastic collar 2 can be pulled up or down on the rod of the trocar body 1 by human power, so as to facilitate the adjustment of the height of the elastic collar 2. Therefore, it is convenient for relevant medical personnel to quickly adjust the depth of the trocar body 1 in the abdominal cavity by utilizing the limiting effect of the elastic collar 2. The operation is extremely convenient and fast, and the cost is low, so it is suitable for mass production and has high practicality.

[0024] Furthermore, as a specific implementation of the present invention, the present invention provides a laparoscopic trocar limiter.

[0025] Specifically, by Figure 1 It is given that the number of trocar bodies 1 is two, the diameter of the rod of one trocar body 1 is 10 mm, and the diameter of the rod of the other trocar body 1 is 5 mm. The material of the elastic ring 2 is rubber, and the number of the elastic ring 2 is two, the outer diameter and inner diameter of one elastic ring 2 are 15 mm and 9.8 mm respectively, and the outer diameter and inner diameter of the other elastic ring 2 are 10 mm and 4.8 mm respectively.

[0026] In the utility model, rubber is a high-elastic polymer compound, whose molecular chains can be cross-linked and vulcanized. When the cross-linked material is deformed by external force, it has the ability to recover quickly and has good physical and mechanical properties and chemical stability. By setting the elastic ring 2 to be made of rubber material, it is not only light in weight but also low in manufacturing cost. At the same time, when the diameters of the rods of the two trocar bodies 1 are 10mm and 5mm respectively, and the outer diameters and inner diameters of the two elastic rings 2 are 15mm and 9.8mm and 10mm and 4.8mm respectively, the elasticity of the two elastic rings 2 is utilized to create friction between the rods of the two trocar bodies 1 and the two elastic rings 2, thereby facilitating the movement of the two elastic rings 2 by manpower and limiting the two trocar bodies 1 by the two elastic rings 2 in the absence of manpower.

[0027] Furthermore, as a specific implementation of the present invention, the present invention provides a laparoscopic trocar limiter.

[0028] Specifically, by Figure 1 It is shown that the outer ring of the elastic collar 2 is integrally formed with anti-skid particles.

[0029] In the utility model, the friction between the human hand and the elastic collar 2 is increased by providing the anti-skid particles, thereby making it easier for human to adjust the position of the elastic collar 2 on the rod of the trocar body 1.

[0030] Working principle:

[0031] To facilitate the relevant medical personnel to quickly adjust the depth of the trocar body 1 in the abdominal cavity:

[0032] First, the elastic collar 2 is put on the outside of the trocar body 1. By setting and utilizing the elasticity of the elastic collar 2, it is difficult for the elastic collar 2 to move on the rod of the trocar body 1 without human power. Then, the elastic collar 2 can be pulled up or down on the rod of the trocar body 1 by human power, so that the height of the elastic collar 2 can be adjusted easily. Therefore, it is convenient for relevant medical personnel to quickly adjust the depth of the trocar body 1 in the abdominal cavity by utilizing the limiting effect of the elastic collar 2. The operation is extremely convenient and fast, and the cost is low. It is suitable for mass production and has high practicality.

[0033] Rubber is a high-elastic polymer compound whose molecular chains can be cross-linked and vulcanized. When the cross-linked material is deformed by external force, it has the ability to recover quickly and has good physical and mechanical properties and chemical stability. By setting the elastic ring 2 to be made of rubber material, it is not only light in weight but also low in manufacturing cost. At the same time, when the diameters of the rods of the two trocar bodies 1 are 10 mm and 5 mm respectively, and the outer diameters and inner diameters of the two elastic rings 2 are 15 mm and 9.8 mm and 10 mm and 4.8 mm respectively, the elasticity of the two elastic rings 2 is utilized to create friction between the rods of the two trocar bodies 1 and the two elastic rings 2, thereby facilitating the manual movement of the two elastic rings 2 and limiting the two trocar bodies 1 by the two elastic rings 2 in non-manpower conditions.

[0034] By providing the anti-skid particles, the friction between the human hand and the elastic collar 2 is increased, thereby making it easier for human to adjust the position of the elastic collar 2 on the rod of the trocar body 1.

[0035] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
