Abstract

The efficient catching device that this utility model provides, arrest bar and arrest cover, described arresting described in the connection of bar one end arrests cover, wherein, described cover of arresting comprises and multiplely arrests a ring, described multiple one end of arresting a ring is fixedly connected with described bar of arresting, and adjacent arrests an interannular for laminating portion, globulate after launching.Solving existing efficient catching device, to arrest accuracy low, causes the problem that operation risk is high.Thus be easy to operation, quick arrest net in solid space, comprehensive covering seal wire institute is through territory, chamber, seal wire can be caught fast, accurately, substantially reduce in interventional therapy for the seal wire of arresting and the time of setting up track, both be conducive to the time that shortening doctors and patients expose under X-ray, turn improve efficiency and the safety of operation.

Description

Efficient catching device

Technical field

This utility model relates to medical device and prosthesis technical field, particularly relates to efficient catching device.

Background technology

Interventional therapy is the medical procedure being widely used in diagnosis and treatment in human body at present, in performing the operation, just needs special catching device in human body, set up the guidewire track of conveying stopper in advance as needed Cardiac catheterization shutoff at congenital heart disease.Catching device plays the effect of setting up arteriovenous track for arresting seal wire in percutaneous puncture in treating ventricular septal defect, patent ductus arteriosus operation.General catching device comprises PTFE sleeve pipe, titanium-nickel wire and arrests the collar, the collar of arresting wherein arrests silk by one to encompass roughly ring shape, it is two-dimension plane structure, thus cause it to be not suitable for operating in the blood vessel, especially malfunction, it is not high to arrest probability, can not arrest fast, cause operating time to extend, increase medical-risk.

, all there is a great drawback in the catching device that all hospitals in the current whole world use in congenital heart disease Occlusion therapy, is namely difficult to Quick Catch and lives seal wire.Because the shutoff of congenital heart disease Transcatheter and the operation of other Cardiac catheterization are treated focus local under the guiding of image documentation equipment, by the bidimensional image figure of device display screen, doctor can only judge whether catching device has enclosed seal wire, but due to the limitation of vision of two dimensional image, the seal wire be positioned at above or below catching device is usually considered as catching by doctor by mistake.Thus some operation normal needs the at substantial time for catching seal wire, operating time is caused to extend, the increase of operating time then means the increase of patient and doctor's open-assembly time under X-ray, and once human body accepts the dosage that X-ray reaches certain, acute radiation injury or chronic radiation injury will be caused, cause abnormity dermatitis, gene mutation and cancer morbidity increase etc., both impaired sufferer, be also unfavorable for the health of these type of operation medical personnel of long campaigns.

Utility model content

The efficient catching device that the purpose of this utility model is to provide.Solving existing efficient catching device, to arrest accuracy low, causes the problem that operation risk is high.

In order to achieve the above object, the efficient catching device that this utility model provides, comprise: arrest bar and arrest cover, described arresting described in the connection of bar one end arrests cover, wherein, described in arrest cover and comprise and multiplely arrest a ring, described multiple one end of arresting a ring is fixedly connected with described bar of arresting, adjacent arrests an interannular for laminating portion, globulate after launching.

In a preferred embodiment, described multiple quantity of arresting a ring is 3,4,6 or 8.

In a preferred embodiment, multiple silk of arresting a ring is bandwire.

In a preferred embodiment, the silk of described bandwire is wide is 0.8 ~ 1.2mm.

In a preferred embodiment, described multiple annular of arresting a ring is waveform ring.

In a preferred embodiment, arrest described in a ring be memory alloy material arrest silk.

In a preferred embodiment, arrest described in a ring be titanium-nickel wire material arrest silk.

In a preferred embodiment, also comprise: handle, described handle is fixedly connected with the described other end of arresting bar.

In a preferred embodiment, the sidewall of described handle offers multiple groove, and the bottom of described groove is arc.

In a preferred embodiment, also comprise: silica gel damping sleeve, described silica gel damping sleeve is connected with the external mounting of described handle.

As shown in the above, the beneficial effects of the utility model are, efficient catching device structure in this utility model is simple, be easy to operation, quick arrest net in solid space, cover seal wire institute through territory, chamber comprehensively, seal wire can be caught fast, accurately, to substantially reduce in interventional therapy for the seal wire of arresting and the time of setting up track, be both conducive to shortening the time that doctors and patients expose under X-ray, and turn improved efficiency and the safety of operation.
