Abstract
The utility model relates to a negative-pressure puncture biopsy needle, which comprises a negative-pressure aspirator, an outer needle and an inner needle. The outer needle consists of a needle base and a hollow needle body, a cavity is disposed inside the needle base and provided with a hole matching with the outer diameter of the inner needle, a hose connected with the negative-pressure aspirator is disposed in the middle of a body of the cavity, one end of the hollow needle body is a needle mouth provided with an incline cutting surface while the other end is fixedly connected onto the needle base, the inner needle is a solid needle, the rear of the solid needle is provided with a handheld handle, the inner needle is inserted from a rear end hole of the needle base of the outer needle, and the front end of the inner needle penetrates through the hollow needle body of the outer needle. The negative-pressure puncture biopsy needle has the advantages that during use, the outer needle is guided via an external device to be inserted in lesion locations, then the inner needle is withdrawn or pulled out, then negative pressure is exerted to suck partial lesion tissues and cells in the hollow outer needle and the negative-pressure aspirator, the hollow needle rotates to cut off and take out the lesion tissues, and an operator can control advancing depth and perform multipoint biopsy on lesions from different angles and directions. The negative-pressure puncture biopsy needle is applicable to different levels of hospitals.
Description
Technical field:
This utility model relates to a kind of diagnosis, surgery, authenticate technology, especially relates to a kind of negative pressure aspiration biopsy pin.
Background technology:
For will find the cause of disease exactly, need focus is carried out biopsy when diagnosing the illness, the doctor obtains a certain amount of biological tissue with medical apparatus and carries out pathological analysis from focus, so that symptomatic treatment.Common in the prior art utensil is for playing rifle formula biopsy needle, and this device is discharged by built-in spring and makes biopsy needle carry out biopsy at intralesional; Measure on various during use is punctured to focus with biopsy needle down as guiding such as B ultrasonic, CT, retracting spring then, and biopsy needle if once obtain tissue, then need repeat above-mentioned action then fast in the intralesional puncture, increases the damage probability; Simultaneously, because dynamics is made of spring, the degree of depth of wayward biopsy needle etc. are difficult to the other focus of important organ is carried out biopsy, play rifle formula biopsy needle and can not obtain cytologic specimen, then can not use the fluidity focus, have limited use.
The utility model content:
The purpose of this utility model is the negative pressure aspiration biopsy pin that a kind of novel structure, reliable operation are provided at the prior art weak point.
The purpose of this utility model is to realize by following measure: a kind of negative pressure aspiration biopsy pin, include vacuum extractor, and its special character is: also have outer pin, interior pin; Described outer pin is made up of needle stand and hollow needle body, described needle stand endosome has a cavity, cavity is provided with and the suitable hole of interior pin external diameter, cavity cavity middle part is provided with the flexible pipe that joins with negative pressure source, described hollow needle body one end is the pin mouth that has oblique section, and hollow needle body body body is provided with scale, and the hollow needle body other end is fixed on the needle stand, pin is real core pin in described, and real core Aculeata is provided with hand holding handle; In described pin by outer pin needle stand after stomidium insert, front end passes outer pin hollow needle body, the same outer pin syringe needle of interior pin syringe needle remains on the same oblique section.
Described outer pin hollow needle body outer rim is provided with the scale card that can move along its outer rim.
Described outer pin pin mouth periphery is sharp keen cutting edge, and is provided with symmetric chamfering.
The real core pin of pin syringe needle is sharp two rib shapes in described, with outer needle set the oblique section of equal angular is arranged.
The stomidium insert division is provided with sealing ring behind described interior pin and the outer pin needle stand.
Compared with prior art, adopted the negative pressure aspiration biopsy pin that the utility model proposes, has following advantage: insert lesions position by the outer pin of external equipment guiding during use, interior subsequently pin is taken out and is moved back or extract, applying negative pressure again sucks part lesion tissue and cell in outer pin of hollow and the vacuum extractor, can rotate the outer pin of hollow can cut away lesion tissue, take out, the degree of depth is carried out in operator's control, by different angles and direction focus is carried out multiple-point biopsy, can avoid passing in and out repeatedly the possibility on lung surface, reduce the possibility of pneumothorax and hemoptysis.Operation is very easy, little to patient's damage, is suitable for hospitals at different levels and uses.
Description of drawings:
Fig. 1 is the sketch map of an embodiment the utility model proposes.
Fig. 2 is Figure 1A portion enlarged drawing.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated:
In an embodiment of the present utility model shown in Figure 1, among the figure, a kind of negative pressure aspiration biopsy pin includes vacuum extractor 1, outer pin 2, interior pin 3.Described vacuum extractor can adopt standard or locking type syringe usually, described outer pin is made up of needle stand 21 and hollow needle body 22, described needle stand endosome has a cavity, cavity is forward and backward to be provided with and hollow needle body outer rim, the suitable hole of interior pin outer rim, cavity cavity middle part is provided with the flexible pipe 23 that joins with negative pressure source, described hollow needle body one end is the pin mouth 24 that has oblique section, as shown in Figure 2.Described pin mouth periphery is sharp keen cutting edge, and is provided with symmetric chamfering.Hollow needle body body body is provided with scale 25, and hollow needle body 22 other ends are fixed on the needle stand 21, and described interior pin 3 is real core pin, and the real core pin of interior pin syringe needle is sharp two rib shapes, and interior pin syringe needle and outer needle set have the oblique section of equal angular.Interior nook closing member Aculeata is provided with hand holding handle 31; In described pin by outer pin needle stand after stomidium insert, front end passes outer pin hollow needle body, the same outer pin syringe needle of interior pin syringe needle remains on the same oblique section.
This utility model has also been taked following measure:
Described outer pin hollow needle body outer rim is provided with the scale card 4 that can move along its outer rim, the degree of depth that prediction is earlier inserted before the infra pin, usually can adopt the method for CT, B ultrasonic or DSA guiding to determine the focus position, with the scale card screens corresponding scale of pin hollow needle body outer rim place outside, prevent to cause accidentally inserting needle dark excessively again.Only the needle point place is sharp keen for the existing biopsy needle that uses, and outer pin pin mouth periphery of the present utility model is sharp keen cutting edge, can cut tissue and cell easily.The stomidium insert division is provided with sealing ring 24 behind described interior pin and the outer pin needle stand, and the effect of sealing ring is to guarantee outer intravital sealing of pin hollow pin and vacuum.
Embodiment of the present utility model has been described above in conjunction with the accompanying drawings; the structure that embodiment provides does not constitute restriction of the present utility model, and those skilled in the art make various distortion within the scope of the appended claims or revise all in protection domain in this area.
