Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, and be not used in restriction this utility model.
Refer to Fig. 1 and Fig. 3, a kind of Endometrical cell collector that this utility model embodiment provides, it comprises interior bar 1 and is placed on the sleeve pipe 3 on interior bar 1, interior bar 1 front end is provided with the collection ring 2 that can draw in sleeve pipe 3.See also Fig. 2, Fig. 4 and Fig. 5, gather ring 2 and comprise two symmetrically arranged collection lobes 21, the outside of each collection lobe 21 convexes with the scraping blade 22 at multiple intervals.Two two ends that gather lobe 21 are connected; Each lobe 21 that gathers is strip, and its cross section is flat, and the side that gathers lobe 21 is the inclined-plane 211 being obliquely installed towards the relative inner of this collection lobe 21.
Gather ring 2 and stretch into while gathering cell sample in uterus, it gathers lobe 21 middle parts and opens, and the scraping blade 22 gathering on lobe 21 also opens.In rotating, bar 1 drives collection ring 2 to rotate, and makes scraping blade 22 scrape cell, to gather.Be set to by the side that gathers lobe 21 inclined-plane 211 being obliquely installed towards the relative inner of this collection lobe 21, in the time gathering ring 2 rotation, the side that gathers lobe 21 also can scrape cell, improves the amount that scrapes cell; In addition, in the time that collection ring 2 closes in sleeve pipe 3, two collection lobes 21 are close, and formation receiving space between the inclined-plane 211 of a collection lobe 21 and another collection lobe 21, to deposit cell sample, prevents that the sample gathering is extruded, the sample size of raising collection.And the cell that the side that gathers lobe 21 scrapes also can directly leave in the receiving space of formation, improve the collected specimens amount of collecting efficiency.
Refer to Fig. 2, Fig. 4 and Fig. 5, in the present embodiment, two the relative sides that gather lobe 21 are all the inclined-plane 211 being obliquely installed towards the relative inner of this collection lobe 21.So not only can increase by two gather lobes 21 near time the volume of receiving space that forms, improve collected specimens amount; In addition, can also not limit the rotation direction that gathers ring 2 while gathering cell, make to gather ring 2 positive and negative rotations, its side that gathers lobe 21 all can be scraped kinetocyte.Certainly, in other embodiments, also can only a side that gathers lobe 21 be made as to inclined-plane 211.
Further, gather the angle of inclination difference on the inclined-plane 211 of the relative both sides of lobe 21.The angle of inclination on the inclined-plane 211 of the relative both sides of collection lobe 21 is made as to difference, and a side that gathers like this lobe 21 is relatively sharp keen, and more convenient scraping cell also can improve the intensity that gathers lobe 21.
Further, the relative inner that gathers lobe 21 convexes with reinforcement 212, and reinforcement 212 is along gathering lobe 21 length direction settings.Relative inner at collection lobe 21 arranges reinforcement 212, can increase the intensity that gathers lobe 21, in the time that two collection lobes 21 open rotation collection cell, prevents that two collection lobes 21 are wound around mutually, to carry out better cell sample collection.
The shapes such as the cross section of reinforcement 212 can be square, rectangle, semicircle, its position is positioned at the mid portion that gathers lobe 21 relative inner.It can certainly be the position near a side.In certain embodiments, gathering the inclined-plane 211 of lobe 21 both sides can be connected with reinforcement 212, and the part gathering between the inclined-plane 211 of lobe 21 both sides is all convexly equipped with out reinforcement 212, to improve the intensity of collection lobe 21.In the present embodiment, reinforcement 212 only accounts for the part in region between the inclined-plane 211 that gathers lobe 21 both sides, thereby increases the receiving space forming.
Refer to Fig. 3, interior bar 1 comprises the leading portion 12 that the front end bending of 11He You extension, extension 11 is extended, and leading portion 12 is connected with collection ring 2.By the leading portion of interior bar 1 12 and extension 11 bending settings, can make to gather ring 2 has larger acquisition range in the time of scraping cell.With the pipe of in prior art, sleeve pipe 3 being made to bending, and interior bar 1 gathers the scheme of relatively soft straight-bar, in the present embodiment, interior bar 1 is made as to relatively hard bending bar, can make to improve to gather the acquisition range of ring 2 and gather ring 2 intensity of scraping kinetocyte.
Particularly, the span of the bending angle α between leading portion 12 and the extension 11 of interior bar 1 is 150-170 degree.Collection ring 2 is stretched in uterus guaranteeing easily, the acquisition range that simultaneously makes to gather ring 2 is suitable, and while preventing that acquisition range is too small, collection capacity reduces, and scratch gathered person while preventing that acquisition range is excessive.Preferably, bending angle α value is 165 degree.
Refer to Fig. 2 and Fig. 3, gather lobe 21 in the time drawing in, axially go up in sleeve pipe 3, two scraping blades 22 that gather on lobe 21 stagger mutually.Thereby in the time that collection lobe 21 closes up income sleeve pipe 3, its small volume, to can take in glidingly in sleeve pipe 3.Meanwhile, gather scraping blade 22 on lobe 21 and stagger, be also convenient to collect more cell.
Gather ring 2 and be formed in one with interior bar 1, can be mold injection molding, easy to make, use material is medical macromolecular materials.
Gather that ring 2 has the stiff end 24 that is connected with the front end of interior bar 1 and with stiff end 24 relative free end 23, this free end 23 is hemispherical, in other embodiments, this free end 23 also can arrange and be cone, or is the cones such as olivary body.Thereby can prevent from gathering ring 2 in the time stretching into uterus or gathering when cell, scratch human body, increases its safety.
Refer to Fig. 6 and Fig. 7, Endometrical cell collector also comprises the anti-turning handle 4 that prevents that interior bar 1 from rotating, and anti-turning handle 4 is installed on the rear end of interior bar 1.Anti-turning handle 4 is set can so that hand-held, skid while preventing from rotating interior bar 1.Interior bar 1 can be connected with anti-turning handle 4 bondings, also can be one-body molded.In the present embodiment, anti-turning handle 4 axially offer installing hole 41, interior bar 1 is inserted in installing hole 41, by interference fit, interior bar 1 is connected with anti-turning handle 4.The outer surface of anti-turning handle 4 is provided with anti-slip tank 42, holds to facilitate, and prevents from skidding.
Refer to Fig. 1 and Fig. 6, anti-turning handle 4 diameters are greater than sleeve pipe 3 internal diameters, can prevent sleeve pipe 3 landings.On sleeve pipe 3, footage number graduation mark can also be set, as uterine cavity degree of depth sign.On sleeve pipe 3, shrink ring 31 can also be set, shrink ring 31 is for axially inwardly shrinking the edge, somewhere of sleeve pipe 3 to form perpendicular to sleeve pipe 3.Shrink ring 31 is set, so that after interior bar 1 inserts in sleeve pipe 3, have suitable frictional force between sleeve pipe 3 and interior bar 1, when preventing in the time gathering or gathering ring 2 and take out, the relative sliding between sleeve pipe 3 and interior bar 1, to gather better cell sample.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
