Description
Technical field
The utility model is related to a kind of tumor marker needles, belong to area of medical devices.
Background technology
According to statistics, the incidence of lung cancer is located at forefront in current all kinds of cancers, is most commonly seen one of cancer disease,
For tumor resection, in the preoperative tumour can be carried out accurately to position or mark being to determine the operation success
One of key, compared to the tumour of other positions, lung tumors are the organs for being most difficult to be positioned or marked, and reason exists
In breathing is the vital sign of human normal, as long as not yet dead, then no matter under what circumstances the lung of people all can be always
Work, and in the process of lung's work, lung can constantly expand with breathing, shrink reciprocation cycle, thus in lung
Position of the tumour either in lung either can not all determine that this just directly leads relative to the position of inside of human body
It has caused no matter which kind of existing contrast apparatus to carry out preoperative radiography using can not all to position the tumour in lung, and it is current
Way be this side for being marked to lung using gentian violet isoreactivity dyestuff, however being marked using dyestuff in the preoperative
Formula marks the time short, and the dyestuff of label is fallen in the very short time by body metabolism, leads to mark ineffective, hardly possible when actual operation
Where position to find tumour, and existing puncture needle volume is larger, and insertion is relatively difficult, and therefore, it is necessary to further change
Into.
Utility model content
The technical problems to be solved in the utility model overcomes existing defect, provides a kind of tumor marker needle, using
The device of label and fixed tumour that chemical agent is combined with physics mode, by ordinary syringe in hollow pipe injectionization
Medicament is learned puncture needle is carried out with puncture injector to puncture the mode being combined, and the auxiliary of hangnail by puncture needle and thereon
The tumour that chemical agent marks is fixed and marks the time longer so that more will can thoroughly be swollen when operation excision
Tumor removes, and main hangnail and auxiliary hangnail can reduce this device in folding and unfolding to groove under the constraint effect of puncture needle needle guard
Volume, when puncture needle needle guard is taken away, main hangnail is strutted the position progress to tumour with auxiliary hangnail under the action of the spring
It is fixed, it can effectively solve the problems in background technology.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution：
A kind of tumor marker needle, including puncture needle needle guard and puncture needle, the puncture needle are set to puncture needle needle guard inner cavity, institute

Slot side is equipped with the second groove, and the second movable rotation-shaft is equipped in second groove, is equipped on second movable rotation-shaft auxiliary
Hangnail is equipped with spring, the puncture between the main hangnail and the auxiliary hangnail side and the first groove, the second groove inner wall
Needle one end is equipped with syringe needle, and through-hole is equipped at the puncture needle lumen centers, hollow pipe, described hollow pipe one end are equipped in through-hole
Needle point is connected through syringe needle, multiple fluid holes are uniformly provided on the needle point.
Furthermore, the puncture needle needle guard is equipped with convex block, and convex block outer wall is equipped with slip-resistant texture.
Furthermore, described hollow pipe one end is equipped with and the matched connector of syringe.
Furthermore, the end position of the main hangnail is hook-shaped, and the tip direction of the main hangnail is along far from syringe needle
Direction topple over.
Furthermore, the end position of the auxiliary hangnail is hook-shaped, and the tip direction of the auxiliary hangnail is along close to syringe needle
Direction topple over.
Furthermore, the syringe needle is an integral structure with needle point.
The utility model advantageous effect：A kind of tumor marker needle involved by the utility model, simple in structure, design is closed
Reason, it is past empty by ordinary syringe using the device of label and fixed tumour that chemical agent is combined with physics mode
Injected chemical medicament carries out puncture needle with puncture injector to puncture the mode being combined in heart pipe, and by puncture needle and thereon
The auxiliary of hangnail the tumour that chemical agent marks is fixed and marks the time longer so that can be more when operation excision
It is thorough tumour is removed, main hangnail and auxiliary hangnail can subtract in folding and unfolding to groove under the constraint effect of puncture needle needle guard
The small volume of this device, when puncture needle needle guard is taken away, main hangnail is strutted under the action of the spring with auxiliary hangnail to swollen
The position of tumor is fixed, highly practical.
