Problems solved by technology
Because the implantation of an atrial shunt needs to release the left atrium and right atrium of the implant sequentially by controlling the relative movement between different parts of the delivery system multiple times, the control is difficult, and the accuracy of the control will directly affect the release effect
If the push distance is too long, the implant risks falling into the left atrium, and if the push distance is too short, it will affect the release of the right atrium portion
In the existing technology, only relying on the operator's experience to manually control, which is likely to cause positioning errors, resulting in implant fall-off, and surgical failure

Embodiment Construction
[0042] The invention will be described in more detail hereinafter with reference to the accompanying drawings showing embodiments of the invention. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In these drawings, the size and relative sizes of the hierarchical regions may be exaggerated for clarity.
[0043] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accor...

The invention provides an implant conveying system which comprises a first handle connected with an outer sheath tube, a second handle connected with an inner push rod and an implant loading device arranged at the far end, away from the second handle, of the inner push rod. The outer sheath tube can be axially adjusted and moved relative to the first handle, and the inner push rod can be axially adjusted and moved relative to the second handle; a connecting assembly is further arranged between the first handle and the second handle, and after the first handle and the second handle are connected through the connecting assembly, the inner push rod is arranged in the outer sheath tube in a penetrating mode. According to the implant conveying system provided by the invention, the implant release speed and distance at each stage can be effectively controlled, and compared with a mode of directly pushing the implant through manual control in the prior art, the controllability of implant release is realized; and a release accident caused by a control error formed by pushing of the inner push rod or retreating of the outer sheath tube in the implant release process is effectively prevented.
Description
technical field [0001] The invention relates to the technical field of medical device design, in particular to an implant delivery system. Background technique [0002] Heart failure (heart failure) referred to as heart failure refers to the failure of the venous return blood to fully discharge the heart due to the dysfunction of the systolic function and / or diastolic function of the heart, resulting in blood stasis in the venous system and insufficient blood perfusion in the arterial system. Circulatory Disorder Syndrome. Heart failure is a serious disease with high morbidity and mortality. According to the location of heart failure, it can be divided into left heart failure, right heart failure and whole heart failure. According to the clinical manifestations of heart failure, it can also be divided into systolic heart failure. Heart failure and diastolic heart failure, among which diastolic heart failure (diastolic heart failure, DHF) accounts for about half of all heart...
