Detailed Description

The invention is further described with reference to the following detailed drawings in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the implementation of the invention easy to understand.

Example 1

Referring to fig. 1-4, in this embodiment, a cervical curettage device includes a sampler and an outer sheath 2.

The sampler comprises a handheld part 5 and a sampling part 6, wherein the sampling part 6 is provided with bristles 601.

The outer sheath 2 is of a tubular structure with two open ends and a hollow interior, and can be penetrated by a sampler; for guiding the sampler so that the sampling portion 6 of the sampler smoothly enters the interior of the cervical canal.

The outer sheath 2 is of a tubular structure with two open ends and hollow inside, the outer sheath 2 needs to be matched with the existing probe 1 for use in a specific use process, the probe 1 is an existing medical device, the probe 1 is applied to the probing direction of a cervical canal, can be used for probing the travelling direction, the length and the cervical proportion of the cervical canal, can also be used for detecting whether the cervical canal is subjected to narrow adhesion and the tightness of an internal cervical opening, the probe 1 is mainly used for searching the position of the internal cervical opening, as shown in fig. 3, when the existing probe 1 is used for searching the position of the internal cervical opening, namely one end of the probe 1 penetrates through the vagina to enter the interior of the cervical canal, then the outer sheath 2 is sleeved outside the probe 1, the outer sheath 2 is pushed to move along the direction of the probe 1, when one end of the outer sheath 2 enters the cervical canal, the probe 1 is taken out, the position of the outer sheath 2 is kept motionless, the sampler is inserted along the interior of the outer sheath 2 until the sampling part 6 of the sampler is inserted into the interior of the cervical canal, the cervical canal slightly, the sampler is pulled out of the cervical canal after the sampling part 6 is slightly, the end of the sampler is pulled out of the cervical canal 6, and the sampler 6 is pulled out of the cervical canal, and the sampler 6 is rotated, thus the sample is prevented from contacting the end of the external cervical canal 6, and the sampler 6 is pulled out of the cervical opening, and the sampler 6 is turned.

The invention can be better matched with the existing probe 1 to use by arranging the outer sheath 2 and the sampling part, and finish tissue sampling in the cervix of a patient with severe cervical atrophy or surgical scar, wherein the outer sheath 2 is matched with the probe 1 to quickly find the entrance of the cervical canal, and the outer sheath 2 can prevent the sampler from contacting with the inner wall of the vagina in the sampling process, so that the sampling is inaccurate.

Example 2

Referring to fig. 1, 2 and 4, on the basis of the solution of the above embodiment 1, a negative pressure channel 10 is provided in the sampler for communicating the hand-held portion 5 and the sampling portion 6, an adsorption hole 602 is provided in the sampling portion 6, and a negative pressure component is provided at one end of the hand-held portion 5 far from the sampling portion 6 and is communicated with the negative pressure channel 10.

Wherein, the inside negative pressure passageway 10 that is provided with of sampler, the absorption hole 602 and the outside intercommunication on the negative pressure passageway 10 are passed through to the one end on sampling portion 6, the other end of negative pressure passageway 10 passes through negative pressure component and forms the negative pressure, reach the adsorption effect, when the brush hair 601 on sampling portion 6 rotates and contacts with the cervical canal inner wall, sampling portion 6 scrapes the cell tissue of getting the cervical canal inner wall, because the cervical canal inner wall usually has mucus, so the cell tissue of scraping is less, produce the negative pressure through negative pressure component, the cell tissue of scraping can follow the inside of mucus along with the negative pressure of absorption hole 602, from this can carry out sufficient sampling, it is to be noted that negative pressure component can be the conventional tubular body constitution that has the piston, the piston is when removing for negative pressure passageway 10 produces the negative pressure, negative pressure component also can be for the pump body constitution of bleeding, adsorb the inside negative pressure passageway 10 through the aspiration pump.

Example 3

Referring to fig. 1 and fig. 4, on the basis of the above embodiment 1, the outer surface of the outer sheath 2 has scale marks 3, one end of the two end openings of the outer sheath 2 is an input end opening 11, the other end is an output end opening 8, the position of the input end opening 11 is provided with a flange 4, and the output end opening 8 is hemispherical.

Wherein, the surface of sheath 2 has scale mark 3, can be convenient for control the degree of depth of inserting of sheath 2, and flange 4 can be with making things convenient for medical personnel handheld sheath 2 simultaneously, makes things convenient for the propulsion and the pulling out of sheath 2, and sheath 2 also can set up transparent material and constitute, and the condition of probe 1 and sampler business turn over sheath 2 and cervical canal is convenient for, hemispherical output opening 8 can be convenient for the wearing out of sampler and the sheath 2 of being convenient for smoothly enter into the cervical canal inside under the direction of probe 1.

Example 4

Referring to fig. 4, on the basis of the above embodiment 1, the connection portion between the hand-held portion 5 and the sampling portion 6 is provided with a dimple 9.

Wherein, the indent 9 is arranged at the connection part of the hand-held part 5 and the sampling part 6, so that the sampling part 6 can be easily broken off.

Example 5

Referring to fig. 4, on the basis of the above-described embodiment 2, the negative pressure assembly is a hollow rubber ball 7.

Wherein, the negative pressure subassembly adopts hollow rubber ball 7, can be convenient for medical staff control, when the sampler inserts the cervical canal through outer sheath 2, medical staff is with holding in the palm hollow rubber ball 7 all the time, when taking a sample, loosens hollow rubber ball 7 for negative pressure channel 10 produces the negative pressure, adopts the negative pressure subassembly that hollow rubber ball 7 made, has the cost low, easy operating's advantage.

Example 6

Referring to fig. 4, in the above embodiment 1, the end of the sampling portion 6 is in a truncated cone shape, and the diameter of the sampling portion 6 gradually decreases from the direction approaching the hand-held portion 5 to the direction separating from the hand-held portion 5.

Wherein sampling portion 6 adopts the round platform form setting can be convenient for sampling portion 6 to insert the cervical mouth, and when backing back sheath 2 a little simultaneously, when making the front end of sheath 2 be close the cervical outer mouth, can prevent sampling portion 6 from taking off the cervical canal inside.

The foregoing has shown and described the basic principles and main features of the present invention and the advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
