Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a ligation device component. Background Art

[0002] The internal hemorrhoid ligation device is a medical device used to treat internal hemorrhoids, mixed hemorrhoids, lower sigmoid colon and rectal polyps. The transparent suction head of the ligation device and the push ring tube with multiple observation holes can improve the blindness phenomenon during ligation and enhance the reliability and accuracy of ligation.

[0003] The length of the ligation tube on the existing ligation device cannot be adjusted, and the ligation tube and the ligation device are generally integrated. When performing ligation surgery on different positions of the patient, it is necessary to replace ligation tubes with different lengths to perform the ligation surgery on the patient, which causes the doctor to spend time selecting ligation devices with ligation tubes of different lengths for surgery, thereby reducing the operating efficiency of the ligation surgery. At the same time, in order to improve the safety of the ligation surgery, the ligation device needs to be disassembled and maintained regularly. Since the ligation device is generally fixed by fasteners, the disassembly of the ligation device is cumbersome and inconvenient to maintain the ligation device.

[0004] According to the publication number: CN208808584U, an elastic thread automatic ligation device is provided, which belongs to the field of medical devices. The utility model is an elastic thread automatic ligation device, which has a negative pressure suction mechanism that can manually generate continuous negative pressure and an elastic thread component that replaces the traditional rubber sleeve ligation target tissue. The elastic thread component is fixed to the ligation device housing through a wire tube locking component, and the manual negative pressure suction mechanism is used to generate continuous negative pressure suction, which can safely and stably adsorb the affected tissue, and the elastic thread component is used to replace the traditional rubber sleeve ligation target tissue, and the aperture of the contraction ring sleeve can be gradually reduced by tightening the elastic thread, which can achieve a tighter ligation of the target tissue, and the ligation effect is more prominent; and the overall structure of the ligation device is compact and reasonable, and the operation is flexible and convenient.

[0005] According to the ligation device introduced above, when performing ligation surgery on different positions of the patient, it is necessary to replace ligation tubes with different lengths to perform the ligation surgery on the patient, which causes the doctor to spend time selecting ligation devices with ligation tubes with different lengths for the surgery, reducing the operating efficiency of the ligation surgery. At the same time, in order to improve the safety of the ligation surgery, the ligation device needs to be disassembled and maintained regularly. Since the ligation device is generally fixed by fasteners, the disassembly work of the ligation device is cumbersome and inconvenient to maintain the ligation device. Therefore, we need to propose a ligation device assembly. Utility Model Content
