Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an adjustable blood vessel fixator. Background Art

[0002] As surgical procedures develop towards minimally invasive methods, miniaturization of medical devices is becoming increasingly necessary. Medical devices that can be used through a puncture device and are simple to operate and safe are becoming more and more the mainstream demand and development direction.

[0003] Existing tourniquets have the following three disadvantages

[0004] First: The diameter is too large to pass through the inner diameter of the 11mm puncture device and be inserted into the chest cavity or other lesion areas.

[0005] Second: The operation is complicated, and it is difficult to lock and loosen the tourniquet. In addition, the tightness of the tourniquet is adjusted in multiple stages. If it is too tight, it may easily damage the tissue, and if it is too loose, the hemostatic effect will be poor.

[0006] Third: It cannot be completely locked. During long-term surgical operations, it is easy to move loose, resulting in weakened or ineffective hemostatic function, causing the risk of accidental bleeding to the patient, affecting the success rate of the operation and endangering the patient's life safety.

[0007] Therefore, it is necessary to design an adjustable blood vessel fixator. Summary of the invention

[0008] In view of the above technical problems that the existing tourniquet has a large diameter, is complicated to operate and cannot be completely locked, an adjustable blood vessel fixator is provided. The present invention mainly utilizes a locking structure that can be adjusted to open and close to cooperate with a binding structure, thereby ensuring that the binding is locked while simplifying the volume and operation steps.
