Fixtures for Interventional Medical Devices

Abstract

The invention discloses a fixing device for an interventional medical device, which comprises a fixing component and a gasket provided with a through hole, the gasket is used to fit on the outer surface of an organ, and the fixing component is connected to the gasket in a detachable manner , the inside of the fixed component is provided with a pull wire channel, the pull wire of the interventional medical device passes through the interior of the organ and passes through the through hole and the pull wire channel in turn, the length of the pull wire can be adjusted when the pull wire channel is opened, and the length of the pull wire when the pull wire channel is closed The length is fixed. The above-mentioned fixing device is small in size and simple in structure. At the same time, it is easy to operate and can quickly complete the fixing and adjustment of the stay wire. In addition, the contact area with the stay wire is large, which can avoid damage to the stay wire or failure of fixation, and ensure the safety of the patient. The overall structure of the patient is small and compact, and it fits well with the organs, avoiding the occurrence of blood leakage at the position where the pull wire passes through and bleeding caused by the friction tissue of the base, thereby reducing the chance of complications and rejection reactions.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a fixing device for interventional medical instruments. Background technique [0002] With the continuous advancement of science and technology, percutaneous interventional technology has been widely used in the field of disease treatment. Percutaneous interventional technology is to intervene in the human body through catheters. Plugs and blood vessel filters, etc.) or drugs are placed in the lesion position of the human body, so as to achieve the treatment of the disease. [0003] In order to ensure the best working condition of some interventional medical devices, their working position and posture need to be limited. Therefore, in order to ensure the working position and posture of interventional medical devices, it is necessary to set up a fixing device outside the organ, so as to provide The machine provides good traction. For example, when treating the diseas...

Problems solved by technology

[0004] However, the fixation devices in the prior art are large in size and complex in structure, which are easy to cause complications and rejection reactions to patients; because the diameter of the needle-type stopper is very small (in order to effectively pass through the pull wire), and it is used for a long time, it is easy to cause The failure of the limit of the pull wire will pose a threat to the life safety of the patient; in addition, during the fixation process, it is necessary to use the needle-shaped limit rod to pierce the pull wire. Due to the small diameter of the pull wire, if the passing position is not appropriate, it is easy to cause the pull wire to break. It poses a threat to the life safety of the patient; moreover, due to its large size, it is bound to have a large contact area with the tissue during fixation. The base of the fixation device is a hard object, which will warp at the apex of the heart, resulting in blood leakage from the position where the pull wire passes And base friction tissue produces bleeding and other conditions
