Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a urology surgery catheter anti-break device. Background Art

[0002] Traditional urological surgical catheters are prone to stress concentration during use because they need to be bent and twisted frequently to adapt to the needs of the operation. This stress concentration will cause the catheter material to gradually fatigue after long-term use, thereby reducing the strength and rigidity of the catheter. As the use time increases, the stress will gradually accumulate and increase, which may eventually cause the catheter to break or deform. Traditional urological surgical catheters have some obvious disadvantages during use. First, due to the need for frequent bending and twisting, the catheter is prone to stress concentration, which affects its service life. Secondly, the breakage or deformation of the catheter may have a serious impact on the surgical effect and the safety of the patient. Utility Model Content

[0003] In view of this, the utility model provides a urology surgery catheter anti-breakage device, which can effectively prevent the catheter from breaking or deforming during use.

[0006] Wherein, a plurality of protrusions are arranged on the top of the protrusion block.

[0007] The technical effect of the urology surgery catheter anti-break device provided by the utility model is as follows: by arranging a plurality of raised blocks on the side wall of the catheter body, the uniformity of stress distribution of the catheter when it is bent and twisted can be ensured, thereby avoiding the problem of stress concentration. At the same time, the design of the raised blocks can also increase the rigidity and strength of the catheter, further improving the durability of the catheter. Therefore, the utility model can effectively prevent the catheter from breaking or deforming during use, thereby improving the safety and effect of the operation.

[0008] On the basis of the above technical solution, the urology surgery catheter anti-break device of the utility model can also be improved as follows:

[0009] Wherein, the protruding block is made of a highly elastic material and has an elliptical or rectangular shape.

[0010] Furthermore, the protrusion is made of a highly elastic material and has a circular or elliptical shape.

[0011] Furthermore, the protrusions are distributed in an array on the surface of the catheter body.

[0013] Furthermore, the buffer material layer is made of a highly elastic material, and the shape of the buffer material layer matches the protruding block.

[0014] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the role of the buffer material layer is to increase the flexibility and bending resistance of the catheter body, reduce the stress concentration of the catheter body during the bending process, and improve the durability of the catheter.

[0015] Furthermore, the protrusions are distributed in an array on the surface of the protrusion block.

[0016] Furthermore, the protrusion diameter is smaller than half of the protrusion block radius.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the role of the reinforcing ribs is to improve the strength and rigidity of the catheter body, increase the bending resistance of the catheter body, and prevent the catheter body from breaking or deforming during long-term use. At the same time, the reinforcing ribs can also increase the stability of the catheter body and reduce the shaking and twisting of the catheter body during the bending process.

[0020] Compared with the prior art, the beneficial effect of the urological surgery catheter anti-breakage device provided by the utility model is as follows: by arranging a plurality of raised blocks on the side wall of the catheter body, the uniformity of stress distribution of the catheter when it is bent and twisted can be ensured, thereby avoiding the problem of stress concentration; at the same time, the design of the raised blocks can also increase the rigidity and strength of the catheter, thereby further improving the durability of the catheter; in addition, the utility model can further improve the durability and stability of the catheter by adding components such as a buffer material layer and reinforcing ribs; the buffer material layer can be arranged at the connection between the raised blocks and the catheter body to absorb and disperse the stress generated when the catheter body is bent and twisted; the reinforcing ribs can be arranged between the raised blocks or between the raised blocks and the buffer material layer to improve the strength and rigidity of the catheter; therefore, the utility model can effectively prevent the catheter from breaking or deforming during use, thereby improving the safety and effect of the operation.
