Description
Technical field
This utility model relates to a kind of biopsy needle, and especially a kind of transvaginal puts in the biopsy needle that intravaginal gathers tumor tissues.
Background technology
Ovarian cancer is the gynecologic malignant tumor that mortality rate is the highest, because ovarian tumors is hidden, is in progress rapidly, is lacked specific early symptom and inspection method, during Most patients diagnosis, abdominopelvic cavity has occurred and has extensively shifted and be in late period.After Debulking surgery and chemotherapy, most of patient is likely recurrence or transfer again still, causes survival rate to be difficult to improve.
Owing to lacking specific early symptom, the diagnosis of ovarian cancer mainly relies on the iconography detection meanss such as blood serum tumor markers and ultrasonic, nuclear magnetic resonance.But the Sensitivity and Specificity of the tumor markerses such as CA125 exists larger limitation, ultrasonic and nuclear magnetic resonance is difficult to the differentiation carrying out malignant and benign lesion and early stage recurrence or metastasis accurately.Because the anatomical position of ovary is special, the living tissue pathologic finding that scope etc. is similar cannot be implemented.Therefore, Most patients lacks preoperative pathological diagnosis foundation, and the patient of ascites does not especially occur, and in art, frozen section prompting is pernicious often, carries out the treatments such as Debulking surgery immediately.
For the ovarian cancer patients suspecting recurrence, usually need again perform the operation or accept chemotherapy.But the diagnosis of recurrence also only relies on symptom and sign, tumor markers and imaging examination at present, before enforcement treatment, lack reliable pathology evidence.For ascitogenous patient, feasible Peritoneal Cytology detects, but there is the probability of ascites feminine gender, causes treatment to be incured loss through delay.
At present still lack simple and feasible and the little means of wound obtain living tissue carries out pathologic finding, need to set up a kind of simple and feasible and the little mode of wound obtains living tissue and carries out pathologic finding.Vagina is as women natural lane, and therefore, it is a kind of mode be comparatively suitable for that transvaginal culdocentesis obtains tissue.
Summary of the invention
For solving the problems of the technologies described above, this utility model provides a kind of transvaginal tumor biopsy pin, comprises puncture needle, inner core pin and handle, described puncture needle is hollow, and puncture needle top is inclined-plane, and inner core pin is movably placed in puncture needle, puncture needle tail end connecting handle, is characterized in that
Described inner core pin top is be identical inclined-plane with puncture needle, also has some recurvate circular blades, be provided with groove in rear end in its front end, a snap ring is also provided with before groove, have baffle plate before snap ring, between snap ring and baffle plate, cover has back-moving spring same, is provided with at least two limited posts in groove, limited post is flexibly connected connection one shell fragment, limited post overcoat has spring, shell fragment is provided with a locating dowel, and locating dowel top is inclined-plane forward, inner core backshank end stretches out outside handle
Handle is provided with at least two locating holes, matches with locating dowel, promote inner core backshank end and locating dowel can be made to press down shell fragment, inner core pin is stretched out outside puncture needle, exposes circular blade, until locating dowel ejects location from next locating hole.
A SR also established by handle, and push button can press down shell fragment makes locating dowel depart from locating hole.
On handle in the locating hole of last position, be also provided with a postive stop baffle.
A handrail is also had between puncture needle and handle.
The utility model has the advantage of:
1. obtain pathological tissues by biopsy needle and carry out pathologic finding, the early diagnostic rate of ovarian cancer can be improved, and clearly recur lesion nature as early as possible, avoid treatment to incur loss through delay as far as possible.
2. utilize this natural lane of vagina, obtain tumor tissues, simple and feasible, and at utmost reduce wound.

Detailed description of the invention
This utility model provides a kind of transvaginal to gather the biopsy needle of tumor, comprise puncture needle 1, inner core pin 2 and handle 3, described puncture needle 1 is hollow, puncture needle 1 top is inclined-plane, inner core pin 2 is movably placed in puncture needle 1, puncture needle 1 tail end connecting handle 3, described inner core pin 2 top is be identical inclined-plane with puncture needle 1, some recurvate circular blades 21 are also had in its front end, groove 23 is provided with in rear end, at least two limited posts 24 are provided with in groove 23, limited post 24 is flexibly connected a shell fragment 25, limited post 24 overcoat has spring, shell fragment 25 is provided with a locating dowel 26, locating dowel 26 top is inclined-plane forward, inner core pin 2 tail end stretches out outside handle 3, a snap ring 22 is also provided with before groove 23, a baffle plate 11 is provided with in puncture needle 1, on inner core pin 2, cover has a back-moving spring 27 to be placed between snap ring 22 and baffle plate 11, be provided with at least two locating holes 31 on the handle 3, match with locating dowel 26, promoting inner core pin 2 tail end can make locating dowel 26 press down shell fragment 25, inner core pin 2 is stretched out outside puncture needle 1, expose circular blade 21, until locating dowel 26 ejects location from next locating hole 31.
Also have a SR 32 on the handle 3, push button 32 can press down shell fragment 25 makes locating dowel 26 depart from locating hole 31, and back-moving spring 27 makes inner core pin 2 return original position.
In handle 3, be also provided with a postive stop baffle 33, baffle plate 33 is arranged between last position locating hole 26 and SR 32.
As shown in Figure 1, handle 3 is provided with three locating holes 31 and arranges successively vertically, by biopsy needle by transvaginal puncture posterior fornix, make biopsy needle arrive at affected area, locating dowel is initially located in last position locating hole 31, promote inner core pin 2 tail end, locating dowel 26 presses down shell fragment 25, and inner core pin 2 moves forward and stretches out outside puncture needle 1, and exposes circular blade 21, when exposing the circular blade 21 of half quantity, locating dowel ejects location from second locating hole 31.
Now can select, press SR 32, locating dowel 26 deviates from locating hole 31, back-moving spring 27 makes inner core pin 2 move backward, circular blade 21 scrapes the tissue of affected area simultaneously, and eject until locating dowel 26 gets back to locating hole 31 place, last position, inner core pin 2 is retracted in puncture needle 1.
Maybe can continue driven forward inner core pin 2, make locating dowel 26 move to the 3rd locating hole 31 to locate, expose whole circular blade 21, then length presses SR 32, make inner core pin 2 be retracted in puncture needle 1, all circular blades 21 scrape more affected area tissue simultaneously.
When length presses SR 32, even if locating dowel 26 fails to eject in last position locating hole 31, also can stop by limited baffle plate 33, avoid inner core pin 2 to deviate from from puncture needle 1.
