Background technology
The primary structure of the endometrial tissue sampler of prior art mainly is included in to be equipped with in the end of body and extracts piston, piston rod and handle, and the other end of body is provided with thief hole.The shortcoming of its existence is that extraction mechanism and probe tube are structure as a whole, for guaranteeing the extraction amount, must increase the length of body and piston rod, cause operating difficulties, the more important thing is and to be used for injecting and extracting liquid out (as normal saline to intrauterine, with flushing expansion endometrium, more help sampling); Pipe diameter is big and be rectilinear form, and the bottom, uterus be subtriangular, and the top of body is difficult for influencing the effect of taking a sample near bottom, uterus inner membrance; In addition,, be easy to push piston in the operating process after sampling, cause sample to overflow owing to there is not piston positioning means.
Summary of the invention
The purpose of this utility model just provides a kind of endometrial tissue sampler, the extraction mechanism and the probe tube that exist with the solution prior art are structure as a whole, for guaranteeing the extraction amount, must increase the length of body and piston rod, cause operating difficulties, and can not be used for injecting and extraction liquid (,, more helping sampling) with flushing expansion endometrium as normal saline to intrauterine; The top of body is difficult near bottom, uterus inner membrance, influence sampling effect; And be easy to push piston, the problems that cause sample to overflow in the operating process after sampling.
The technical solution of the utility model is: comprise withdrawal device and probe tube, the interface of probe tube one end is connected with the interface of withdrawal device, described withdrawal device is a syringe construction, constitute by tube-like envelope, piston and piston rod, it is characterized in that: on described piston rod, spacer is housed, this spacer is by being provided with the shoulder shape angle towards piston on this flexure strip radially to the open flexure strip in both sides; Described probe tube is made of body and the probe tube interface that is connected its bottom, and the other end of this body is the round sealed top, is being provided with thief hole near on this vertical tube body wall.
The interface internal diameter of described probe tube is pegged graft with the external diameter of the syringe needle plug of general syringe and is cooperated.
Axle center at the interface of described withdrawal device is provided with conical interface, is provided with the connection overcoat that has internal coiling in the outside of this taper shape interface; The outer peripheral face of the inner peripheral surface of described probe tube interface and the conical interface of described withdrawal device matches, bottom at this probe tube interface is provided with outward flange, is provided with the external spiral that cooperates with the internal coiling of described withdrawal device interface overcoat at the outer peripheral face of this outward flange; Be provided with radial handle in the outside of this probe tube interface.
The top of described probe tube body is slick and sly crooked towards described thief hole one side, is provided with from the top to the length scale of bottom on the surface of this body.
Described probe tube is by transparent and have the elastic medical plastic of certain deformation and make.
The utility model has the advantages that: can adopt general syringe as draw-out device, the diameter of syringe is bigger, can guarantee enough extraction amounts, processing ease.And can inject and extraction liquid (as normal saline) to intrauterine with syringe,, more help sampling with flushing expansion endometrium; The bending at the top of body can make thief hole be adjacent to the inner membrance of the delta-shaped region of bottom, uterus, is beneficial to sampling; Radially handle on the interface is held the rotation body for the operator, so that thief hole is aimed at different position samples.In addition, behind sample drawn, spacer shifts out outside the withdrawal device shell, and spacer utilizes its elasticity to open to both sides, can prevent effectively that sample from overflowing.

The specific embodiment
Referring to Fig. 1～Fig. 6, this embodiment of this utility model comprises withdrawal device P and probe tube Q, and the interface 8 of probe tube Q one end is connected with the interface 1 of withdrawal device P, and described withdrawal device P is a syringe construction, is made of tube-like envelope 7, piston 11 and piston rod 9.On described piston rod 9 spacer 10 is housed, this spacer 10 is by being provided with the shoulder shape angle 15 towards piston on this flexure strip radially to the open flexure strip in both sides.Described probe tube Q is made of body 3 and the probe tube interface 1 that is connected its bottom, and the other end of this body 3 is the round sealed top, is being provided with thief hole 5 near on this vertical tube body wall.
Axle center at the interface 8 of described withdrawal device P is provided with conical interface 12, is provided with the connection overcoat (referring to Fig. 2) that has internal coiling 13 in the outside of this taper shape interface 12.The outer peripheral face of the conical interface 12 of the inner peripheral surface of described probe tube interface 1 and described withdrawal device matches, be provided with outward flange 6 in the bottom of probe tube interface 1, be provided with the external spiral 14 that cooperates with the internal coiling 13 of described withdrawal device interface overcoat at the outer peripheral face of this outward flange 6; Also be provided with radial handle 2 in the outside of this probe tube interface 1.
The top of described probe tube body 3 is crooked towards described thief hole 5 one sides slyness, is provided with on the surface of this body 3 from the top to the length scale 4 of bottom, to show what and the degree of depth that enters the uterus of sampling.
