Description

Tumor marker pin

Technical field

This utility model is related to field of medical device, specifically for a kind of tumor marker pin.

Background technology

According to statistics, the sickness rate of pulmonary carcinoma is located at prostatitis in all kinds of cancers at present, is one of most commonly seen cancer disease.

For tumor resection, tumor accurately can be positioned in the preoperative or labelling is to determine this operation One of key of success.Compared to the tumor of other positions, lung tumors be most difficult to be positioned or labelling organ, its Reason is:

Breathing is the vital sign of human normal, as long as not yet dead, then the pulmonary of people is all under what circumstances Can work always, and in the middle of the process of pulmonary's work, pulmonary can constantly expand with breathing, shrink reciprocation cycle, thus No matter the tumor in pulmonary is position in pulmonary or all cannot determine, this is just with respect to the position of inside of human body Directly results in and which kind of existing contrast apparatus to carry out preoperative radiography using and all the tumor in pulmonary cannot be positioned；

And current way is using Gentian Violet isoreactivity dyestuff, pulmonary to be marked in the preoperative, but entered using dyestuff This mode labelling time of line flag is short, and the dyestuff of labelling is fallen by body metabolism in the very short time, when leading to actual operation Labelling effect on driving birds is not good is it is difficult to the position finding tumor is located.

Utility model content

Goal of the invention of the present utility model is: provides a kind of tumor marker pin, which overcomes drawbacks described above, be capable of Accurate marker to tumor, is particularly suited for the labelling of lung tumors.

The present utility model purpose is achieved through the following technical solutions: a kind of tumor marker pin it is characterised in that: include The puncture needle needle guard of hollow and the labelling nook closing member for being marked to tumor；

The front portion of described labelling nook closing member is activity to be located in puncture needle needle guard inside and axially can move along puncture needle needle guard Dynamic labelling shank, the rear portion of labelling nook closing member is the labelling backshank being exposed at outside puncture needle needle guard；

Be arranged at intervals with described labelling shank forward outer surface multiple along labelling shank length direction distribution for will Labelling shank is fixed on the fixed cell in tumor；Each fixed cell includes at least one pair of tip to labelling shank rear portion side The main agnail that direction tilts；It is installed with needle handle on the outer surface at described puncture needle needle guard rear portion.

Its operation principle and process are as follows:

As in Figure 3-5, during labelling, under the auxiliary of contrast apparatus, puncture needle needle guard is penetrated into pulmonary via thoracic cavity, And allow puncture needle needle guard gently pierce through tumor, after confirming that the insertion of puncture needle needle guard puts in place, fix labelling backshank with handss, with Puncture needle needle guard is extracted out simultaneously and labelling shank is retained in the tumor of pulmonary thus completing labelling by this；

Here, after departing from by puncture needle needle guard from labelling nook closing member, the main agnail of each group on labelling nook closing member launches naturally And it is hooked in the tissue of tumor and tumor vicinity thus completing the fixation of labelling shank, and in order to strengthen the effect of fixation, often Multipair main agnail can be set in individual fixed cell, and each main agnail ring is located on the outer surface of labelling shank surrounding；

Operative doctor is in operation, as long as along the direction incision of labelling nook closing member, labelling nook closing member is consolidated together with its front portion Fixed tumor is excised together.

In order to preferably implement this programme, also provide following prioritization scheme:

Further, it is easy to medical worker and finds the labelling nook closing member of implantation and prevent labelling backshank to be retracted to reach Purpose in pulmonary:

Described labelling backshank is the labeled in vitro bar that can naturally crimp.

Here, labeled in vitro bar follows labelling shank to enter together in human body and be retained in outside pulmonary when piercing In thoracic cavity, now the labeled in vitro bar automatic curled of strip becomes swirling, and the labeled in vitro bar area after curling is big, in operation Easily found by operative doctor, and the labeled in vitro bar area after crimping increases thus is not easy the breathing due to pulmonary and quilt It is brought in pulmonary, and the labeled in vitro bar area after crimping is larger, can facilitate contrast apparatus radiography, be easy to inserting mark After note nook closing member, doctor can find at any time.

Further, in order to reach prevent labelling shank move forward purpose:

Each fixed cell also includes the auxiliary agnail that at least one pair of tip tilts to labelling shank front portion side direction.

Here, by the fixed cell that main agnail and auxiliary agnail form enable to labelling shank fixation more firm, by In two kinds of agnail respectively forwardly rear-inclineds, hereby it is ensured that its position can be fully latched after labelling shank reaches knub position Both will not move forward and will not be moved rearwards by, and in order to strengthen the effect of fixation, can arrange many in each fixed cell To main agnail, each main agnail ring is located on the outer surface of labelling shank surrounding.

Further, in order to reach the purpose enabling tumor marker pin that image to be stayed on radiography:

Described labelling shank and/or labelling backshank are by can make developing material.

Further, block to inserting areas adjacent to reach, prevent the purpose of tissue bleeding:

It is covered with water-swellable layer on the outer surface of described labelling shank.

Here, water-swellable layer is made up of expandable material after absorbing water, and when labelling shank is inserted, water-swellable layer is inhaled Absorb near body fluid and passage plugging when rapid expanding puts into, and further function as fixing work to a certain extent With.

After presently used water suction, expandable material all can use, such as merocel macromolecule hemostasis expanding material, Auspicious hydrogel, high swollen molten chitosan sponge etc. received.

Merocel is the second acetal macromolecular material being generated by polyvinyl alcohol and aldehyde reaction, and it has the hydrophilic of height Property and dilatancy, absorb liquid after can expand rapidly, volume up to original 10 times, thus this material be highly suitable as above-mentioned Water-swellable layer material, best using effect can be reached.

It is for reference, not as to restriction of the present utility model, this area that above-mentioned enumerated material is only used as embodiment Those of ordinary skill should it is conceivable that being substituted using the material that other have same imbibition effect, without departing from Invention thinking of the present utility model, should be considered as all to belong to the category that this utility model is protected.

Second goal of the invention of the present utility model be: provides a kind of tumor marker syringe, its customer service is above-mentioned to be lacked Fall into, be capable of the quick fixation of tumor marker pin, simple to operate.

For technology before relatively, above-mentioned two scheme has the beneficial effect that jointly

1. this utility model is fixed in tumor using labelling nook closing member, when successfully solving prior art using dye marker Between short, the inaccurate problem of labelling；

2. in this utility model, main agnail and auxiliary agnail enable to fixation in tumor for the labelling nook closing member after cooperating Highly stable.
