Description

Disposable wearing pricker clamping device

Technical field

This utility model relates to medical instruments field, is specifically related to a kind of disposable wearing pricker clamping device.

Background technology

Aspiration biopsy is the standard of the various organic disease of current diagnosis (including kidney, liver, lung, mammary gland, thyroid, prostate, pancreas, testis, uterus, ovary), but aspiration biopsy is as a kind of invasive inspection, except may occur in which puncture failure, the complication such as hemorrhage, cross infection is also the major issue particularly merited attention.

For reaching to puncture purpose in clinic, reduce complication, when aspiration biopsy, it is necessary to puncture under ultrasonic guiding in real time, tracking.Fixing device is called biopsy needle hand-held device to puncture biopsy needle with the connection of ultrasonic probe, generally include the fixing device of fixing biopsy needle, widely used metal fixture in current clinic, i.e. stripe U type draw-in groove, during use, is longitudinally through U-lag by biopsy needle, then fix and puncture, but when many cases patient is punctured continuously, sterilization one by one need to be carried out to puncturing fixing device, to avoid occurring between patient cross infection.In clinical position, many employing glutaral disinfectant solutions soak sterilization carried out above in 30 minutes, but for patient and patient, the overlong time of 30min and sterilization effect are still imprecise.Therefore, it is badly in need of a kind of disposable clamping device, to solve the waiting time and better to ensure patient, it is to avoid cross infection.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of patient's of minimizing waiting time, avoids the disposable wearing pricker clamping device of cross-contamination.

In order to solve above-mentioned technical problem, this utility model provides following technical scheme: disposable wearing pricker clamping device, including U-lag body, be provided with in U-lag body removably connect with it one-time fix pad, one-time fixing pad and be provided with overlay film, overlay film pads as removably connecting with one-time fixing, and U-lag body upper and lower is respectively equipped with position limit device and lower caging device, the top of position limit device and U-lag removably connects, and lower caging device is connected for elasticity with the end of U-lag.

Adopt the disposable wearing pricker clamping device of technical solutions of the utility model, one-time fix pad and be removably positioned in U-lag body, after being finished, replaceable one-time fix pad, it is not necessary to sterilization, it is to avoid cross-contamination；Overlay film one-time fixes pad be in gnotobasis for protection, will one-time fix after pad is fixed in U-lag body, then be torn by overlay film, it is to avoid one-time fix pad contaminated when mounted；Position limit device is for fixation from the top one-time fixing pad, and lower caging device is for playing fixation in the bottom one-time fixing pad.

Principle of the present utility model is: during use, pad will be one-time fixed and be installed in U-lag body, during installation, one-time fixing pad and put into U-lag body, lower caging device elasticity is opened, after installing, lower caging device elastic clamping, then overlay film is torn, by puncture needle through one-time fixing in the groove formed pad, position limit device is arranged in the top of U-lag body again, for one-time fixing pad in spacing U-lag body.

The beneficial effects of the utility model are: with the puncture needle retaining mechanism of existing metal U-lag body, one-time fix pad and overlay film ensures that puncture needle is not subjected to pollute in the process punctured, after use completes, what namely more renew one-time fixes pad, avoid cross-contamination, and then U-lag body need not be carried out disinfection and can meet demand, shorten the waiting time of patient.

Further, described position limit device includes lid and upper elastic component, and lid is hinged with the side of U-lag body, and upper elastic component and the upper end one-time fixing pad offset.Lid acts the effect sealing U-lag body, it is to avoid being polluted in the process of use, upper elastic component is at lid and one-time fixes between pad, to one-time fixing the effect paving clamping and positioning.

Further, described lower caging device includes chuck and lower elastic component, and chuck is provided with two and is respectively arranged on U-lag body Nei Bi both sides, and lower elastic component is located in U-lag body between wall and chuck.Chuck plays the transmission of power, for one-time fix pad and contact, lower elastic component can cross-direction shrinkage, thus can one-time fix, pad is horizontal to be clamped.

Further, the described pad that one-time fixes is silica gel block, and silica gel block is longitudinally placed in U-lag body, and silica gel block is longitudinally provided with through hole.Silica gel block has elasticity, and is provided with through hole inside silica gel block, and puncture needle is positioned at silica gel block, it is to avoid pollute, and when be squeezed power time, puncture needle can be clamped.

Further, described upper elastic component is elastic projection, and the lower end of elastic projection and silica gel block offset.Elastic projection is with to one-time fix pad contact surface little, and extruding force is concentrated, and clamping is better.

Further, the lower end of described elastic projection is provided with multiple projection.Multiple projections contact as Multi-contact with one-time fixing pad, and clamping effect is good.

Further, the upper end width of described chuck is less than lower end width.Cross section is taper type, and placement one-time fixes during pad easy to operate.
