However, in the practical application of CGM system, the stability and precision of guide needle have always been one of the key factors affecting system performance.

[0023] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0024] The embodiments of the present disclosure will be described in detail below with reference to the drawings. Embodiments

[0025] As Figures 1-3The utility model provides a connecting structure based on CGM trocar, including

[0026] The needle tube 1 is the main part of the trocar, used for inserting into the body to reach the target position for monitoring or treatment;

[0027] The needle tip 2 is provided at the front end of the needle tube 1 and is the sharpest part of the trocar, used for penetrating the tissue. The design of the needle tip 2 is usually very fine to ensure that it can smoothly penetrate the skin and reduce damage to the surrounding tissue;

[0028] The edge material 3 is connected with the rear end of the needle tube 1, which provides a connecting or fixing point for the subsequent processing of the trocar, and the edge material 3 will be folded before the assembly of the whole machine. The design of the edge material 3 usually considers the stability and firmness of the connection to ensure that the trocar will not fall off or loosen during use;

[0029] The retaining wall 4 is provided on the edge of the needle tube 1 and is arranged in a staggered manner at the position connected with the edge material 3. The main purpose of this staggered design is to enhance the stability and connection strength of the structure. The retaining wall 4 is an additional support structure that can provide additional support and stability when the trocar is subjected to external forces, thereby preventing the needle tube 1 from bending or breaking.

[0030] The distance between the retaining walls 4 is greater than 0.3mm to further ensure the stability and connection strength of the structure.

[0031] The design of the retaining wall 4 staggered by more than 0.3mm can form a structure at the connection, which helps to disperse stress and prevent structural damage caused by stress concentration. When external forces act on the trocar, the staggered retaining wall 4 can absorb and disperse these forces, thereby protecting the overall structure from damage.

[0032] By increasing the distance between the retaining walls 4, the connecting structure can be more difficult to deform when subjected to external forces. This design can enhance the rigidity of the structure, allowing it to maintain a stable form during long-term use.

[0033] Referring to Figure 3 The angle between the retaining wall 4 and the needle tube 1 is a right angle to facilitate manufacturing and maintain the rigidity of the structure.

[0034] The right angle design makes the connection between the retaining wall 4 and the needle tube 1 more simple and direct, reducing the complexity and uncertainty in the processing process. This helps to reduce production costs and improve production efficiency. Moreover, because the right angle is a universally accepted and easily measurable angle, it improves the reliability and consistency of the product. Specifically, the right angle design can provide a stable support structure, allowing the retaining wall 4 to effectively withstand pressure from the needle tube 1 or other external forces, preventing it from deforming when subjected to external forces.

[0035] Referring to Figure 1 and Figure 2 , a transition 5 is provided between the needle tube 1 and the rim 3 for smooth connection between the needle tube 1 and the rim 3.

[0036] The provision of the transition 5 enables smooth connection between the needle tube 1 and the rim 3, which helps to reduce stress concentration at the connection, avoiding cracks or fractures when under stress, while the smooth connection also improves the fluidity of the overall structure and enhances the connection strength between the needle tube 1 and the rim 3. By absorbing and dispersing stress through the transition structure, structural damage caused by stress concentration is prevented, which helps to improve the durability and service life of the guide needle.

[0037] Referring to Figure 1 and Figure 2 , grooves 6 are provided on both sides of the transition 5 for relieving the transition 5.

[0038] The presence of the grooves 6 helps to disperse stress at the transition 5, avoiding structural damage caused by stress concentration.

[0039] When external forces act on the guide needle, the grooves 6 can absorb and disperse these stresses, thereby protecting the transition 5 from damage.

[0040] By relieving the stress distribution of the transition 5, the grooves 6 can enhance the stability of the overall structure, helping to ensure the accuracy and reliability of the guide needle during use.

[0041] Referring to Figure 1 and Figure 2 , the retaining wall 4 is provided with a rounded corner 7 at one end near the groove 6 to reduce damage to the connecting elements or tissues.

[0042] The design of the rounded corner 7 can significantly reduce the stress concentration phenomenon when the retaining wall 4 contacts the connecting elements or tissues. Since the rounded corner 7 has a smooth transition feature, it can disperse stress and avoid excessive pressure at the contact point, thereby reducing the risk of damage to the connecting elements or tissues.

[0043] By providing the rounded corner 7, the connecting elements can be protected from wear and tear or breakage caused by stress concentration. The rounded corner 7 can reduce friction and collisions of the connecting elements during stress, thereby prolonging their service life.

[0044] Referring to Figure 2 , the width of the transition 5 is greater than the width of the needle tube 1 to provide a larger connection area and stronger connection strength.

[0045] The increase in the width of the transition 5 increases the connection area, thereby enhancing the stability of the connection, and the larger connection area helps to ensure a firm connection between the guide needle and other medical equipment or devices, reducing the risk of loose or detached connections and improving the reliability of the overall system.

[0046] Referring to Figure 1 and Figure 2 The needle tube 1, the needle tip 2 and the retaining wall 4 are made by an integrated molding process to improve the integrity and connection strength of the structure.

[0047] The integrated molding process makes the needle tube 1, the needle tip 2 and the retaining wall 4 and other components into one whole, avoiding the problem of loose or detached connections that may occur in traditional connection methods, and helping to improve the stability and reliability of the guide needle during use.

[0048] Through the integrated molding process, the molding process of the entire part can be completed at one time in one mold, without the need for step-by-step processing and additional connections, and the production efficiency is improved and the manufacturing cost is reduced.

[0049] In use of the embodiment of the application: the retaining wall 4 to the plane adopts staggered transition design, increases the strength of the edge material 3, especially in the case that the needle tube 1 is more than 30 mm, it can well improve the situation that the needle tube 1 inclines downward due to its own weight. The downward inclination of the needle tube 1 will cause the needle tip 2 to be bumped and the needle to be skewed and deformed.
