Background technique
With the raising of people's health consciousness, generally in each hospital, cervical carcinoma screening is needed from palace cervical carcinoma screening
Biopsy specimen is taken at neck, clinically used cervical biopsy sampler is mainly cotton swab or Uterine neck bush at present, and this kind of tool is adopted
The biopsy specimen of collection is nonstandard, it usually needs carries out multi-pass operation, and collecting quantity is limited, it is easy to cause mistaken diagnosis or leakage
It examines, certain difficulty is brought to medical work.
Currently, disclosing a kind of novel cervical with the Chinese patent that a notification number is 202458477 U of CN in the market
Biopsy device preferably resolves problem above, but during actual use, not due to different patient's uterine neck interior sizes
Together, therefore the patient excessive for uterine neck, the inconvenient progress of sampling, the too small patient's biopsy device of uterine neck are not easy to be put into and use,
Applicability is relatively narrow.
Summary of the invention
The object of the present invention is to provide a kind of cervical biopsy devices, it is intended to solve the problems, such as that applicability is narrow.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of cervical biopsy device, including
It articulated shaft and first struts piece and second by the way that the articulated shaft is hinged and struts piece, described first struts piece far from institute
The end for stating articulated shaft is provided with the first arc-shaped activity template, and described second struts piece is arranged far from the end of the articulated shaft
There is the second arc-shaped activity template, where the axle center of straight line, second activity template where the axle center of first activity template
Straight line and the articulated shaft axle center where straight line it is conllinear, the diameter of first activity template is less than second activity
The diameter of piece, the second activity template activity fit in the outside of first activity template, and described first struts piece, described second
It struts and offers biopsy hole on piece and first activity template.
The further setting of the present invention are as follows: it further include having the first cutter, the shape of first cutter and described the
One struts piece and the shape of first activity template matches, and movable fit in described first and strut piece and described first living
The inner wall of movable plate.

To reduce compressing and rubbing action of the biopsy device to wound, reduce the pain of patient.The wherein length and thickness in attached drawing
Only schematic diagram not represents actual use size.
During rotation first struts piece 2 and second struts piece 3, the second activity template 5 is to be fitted in the first activity template 4
Outer wall carry out movable, therefore the tissue of patient is prevented to be gripped between the first activity template 4 and the second activity template 5；While the
Also biopsy hole 6 is offered on one activity template 4, therefore can increase the range of sampling.
When cutting to tissue, headlamp 17 struts piece 2 and second for first and struts and illuminate between piece 3, so
The image that endoscope camera head 16 will be seen that afterwards is transmitted on display 18, and doctor observes when can cut, and passes through
One drive rod 8 drives 7 activity of the first cutter, and the first cutter 7 strut 4 activity of piece 2 and the first activity template close to first, and will
It cuts down to drop to first and strut piece 2 and second across the tissue in biopsy hole 6 and strut piece 3；By the after the completion of cutting
One drive rod 8 retracts the first cutter 7, can carry out coating to tissue at this time, when coating can also pass through display 18
Observation coating is carried out, coating effect is good；Equally, the second drive rod 12 can drive the second cutter 11 to be cut, simple side
Just.All there is demister screen outside endoscope camera head 16 and headlamp 17, therefore image can be made relatively sharp.
When driving the first drive rod 8 and the second drive rod 12, make in the limit of the first movable cylinder 9 and the second movable cylinder 13
The position of the first cutter 7 and the second cutter 11 can be kept to stablize with lower so that the first cutter 7 it is stable be fitted in the
One struts the inner wall of piece 2 and the first activity template 4, and the second cutter 11 stabilization is fitted on the inner wall that second struts piece 3；While the
One driving portion 10 and the second driving portion 14 to drive comfort level higher；And first driving portion 10 and the second driving portion 14 may be used also
To prevent the first drive rod 8 from deviating from from the first movable cylinder 9, prevents the second drive rod 12 from deviating from from the second movable cylinder 13, mention
High stability in use.
When rotation first struts piece 2 and second struts piece 3, the first driving handle 19 and second need to only be driven by one hand
Handle 20 is held with a firm grip, and the first driving handle 19 and the second driving handle 20 pass through leverage and first can be driven to strut piece 2 and second
The rotation of piece 3 is strutted, when holding first struts piece 2 and second struts 3 position of piece, also need to only grasp the first driving handle 19 and the
Two driving handles 20, it is simple to operate.
It should be noted that each embodiment in this specification is described in a progressive manner, each embodiment emphasis is said
Bright is the difference from other embodiments, and the same or similar parts in each embodiment may refer to each other.
Foregoing description is only the description to present pre-ferred embodiments, not to any restriction of the scope of the invention, this hair
Any change, the modification that the those of ordinary skill in bright field does according to the disclosure above content, belong to the protection of claims
Range.
