Abstract
The utility model relates to the technical field of cardiac operations, in particular to an axial pull circumferential sampling device. The device consists of a handle, a negative pressure barrel, a piston head, an operating rod, a sampling barrel, a sampling seam, a scraping handle and a plurality of scraping sheets, wherein the handle is positioned in the negative pressure barrel; the lower end of the handle is combined with the operating rod into a whole; the lower end of the handle is sleeved with the cylindrical piston head made of rubber; and the piston head is bonded with the handle, and is in interference fit with the negative pressure barrel; and the annular scraping sheets combined with the scraping handle into a whole are arranged on a side wall of the lower end the scraping handle. The device adopts a negative pressure suction and scraping sheet longitudinally-scraping combined mode, so that mucous membrane epidermis can be sucked into the sampling seam compulsively to ensure sufficient contact among the edges of the scraping sheets and mucous membrane cells; and compared with the prior art, the sampling success rate is increased.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly relate to a kind of axial pull-type hoop sampler.
Background technology
At present, in medical and health industry, often run into clinically the disease of the aspects such as some gynaecologic vaginals, cervix uteri at gynecological and department of obstetrics and gynecology etc., need scraping cervix uteri, vaginal epithelial cell, leucorrhea etc. to be used for Clinical Laboratory and analyze for diagnosing.Usually use at present homemade scraping plate, cotton swab etc., because its size and present situation are lack of standardization, be of rude workmanship, in use cause easily cut and the cross infection of skin, bring unnecessary misery to patient.
Application number is that the mode that 200910164231.5 " sampling sweeping machine " sampling sleeve and rotatable scraping blade combine is scratched to prevent mucosa, but exists following defective in the technical scheme of this patent:
Because the edge of scraping blade is in the sleeve, therefore mucosa and scraping blade is come in contact, its essential condition is, the elasticity of mucosa wall is enough to make mucosa to protrude into the degree of depth in the sleeve above the wall thickness of sleeve.Yet in fact, the mucosa wall elasticity of different people is different, and in the vagina of same person, the mucosa wall elasticity of different parts also is different, and adopts the constant sleeve of wall thickness to be difficult to satisfy various situation.If adapt to above-mentioned different situation, the wall thickness of sleeve is done too thinly, therefore the longitudinally edge of its slot scraping will become cutting edge, stretches at sleeve that its vertical cutting edge still has the situation that vaginal wall is scratched to occur in the process of vagina.
Therefore, in the prior art, also do not have to adapt to the different elastic mucosa wall of not employment, can guarantee again the sampling apparatus of the sampling process that safety and nondestructive is hindered.
Summary of the invention
The present invention provides a kind of simple in structure, easy to use for solving the deficiencies in the prior art, has simultaneously the axial pull-type hoop sampler of better sample effect.
The scheme that solves the technology of the present invention problem is: axial pull-type hoop sampler is made of handle, negative pressure cylinder, piston head, action bars, sampler barrel, sampling seam, handle-scraping method and scraping blade.Wherein, negative pressure cylinder is that the upper end opens wide, as a whole cylinder is combined in the lower end with sampler barrel, has a vertical sampling seam on the lower end closed of sampler barrel, the sidewall, and the wall thickness of sampler barrel is 1.5-2.4mm.Handle is in the negative pressure cylinder, and the lower end of handle is combined as a whole with action bars, and material is that the columniform piston head of rubber is placed in the lower end of handle and bonding with handle, and piston head becomes the interference fit relation with negative pressure cylinder.Action bars is in the sampler barrel, and become clearance fit relationship with sampler barrel, the columniform handle-scraping method of being combined with screw thread with action bars in the lower end of action bars, the diameter of handle-scraping method be action bars diameter 1/2, it is the scraping blade of holistic annular that sidewall in the lower end of handle-scraping method has a plurality of and handle-scraping method, the edge of each scraping blade is with cutting edge, the vertical equidistant arrangement of a plurality of scraping blades.The material of the coalition of handle-scraping method and scraping blade is polytetrafluoroethylplastic plastic.Satisfy following position relationship between described handle, negative pressure cylinder, piston head, action bars, sampler barrel, handle-scraping method, the scraping blade: when the bottom surface of piston head contacted with the bottom surface of negative pressure cylinder, a uppermost scraping blade was in the following position of lower limb of sampling seam.
During operation, first sampler barrel is inserted vagina, and the seam aligning of will taking a sample needs the sample position, upwards spur handle, under the swabbing action of piston head, form negative pressure in the sampler barrel, the mucosa that contacts with sampler barrel protrudes under the swabbing action of negative pressure in the sampling seam, continue upwards to spur handle, the cutting edge of a plurality of scraping blades carries out scraping to the mucosa that protrudes into the sampling seam successively, after having gathered action bars is directly extracted out to get final product from sampler barrel.
Adopt such scheme, can reach following effect:
1. because the mode that this utility model has adopted negative pressure-pumping and the vertical scraping of scraping blade to combine, the mucosa epidermis can be forced to suck in the sampling seam, with mucosa cells sufficient the contact arranged with the edge that guarantees scraping blade, compared with prior art, improved the success rate of sampling.
2. because this utility model has adopted the mode of negative pressure-pumping, the wall thickness of sampler barrel is more thickeied than prior art, this has just been avoided in the conventional art as adapting to the logy situation of mucosa wall, and sampling cylinder wall is done as far as possible thin, but cause the longitudinal edge of slot scraping to form cutting edge, the situation of mucosa wall incised wound is occured.Make sampling operation have higher safety.
3. because this utility model adopts the mode of vertical pull to take a sample, compare with rotation mode of the prior art, operate easier.
