Description

Disposable cell brush with inclined bristles

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to disposable cell brush of brush hair slope.

Background

In clinical medicine, endoscopy is an important auxiliary diagnosis method, and during endoscopy, a disposable cell brush is inserted into a patient body to brush tissue mucus at a diseased part, and then pathological analysis is carried out on the tissue mucus to determine the disease.

The disposable cell brush that uses in endoscopy mainly relies on the brush hair sample, and the brush hair of the disposable cell brush on the existing market is most the upright state, in limited outward appearance space, the brush hair easily takes place to warp to the cell volume that upright brush was got in clinical use brush is few partially, needs the sample many times, can increase sample frequency and sample time, not only can reduce sample detection's efficiency, but also can increase patient's misery.

Therefore, it is necessary to design and develop a disposable cell brush, which does not require frequent sampling, so as to improve the sampling efficiency and reduce the pain of the patient.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a disposable cell brush of brush hair slope to solve the technical problem who provides among the above-mentioned background art.

In order to achieve the purpose, the utility model discloses a disposable cell brush with inclined bristles, which comprises a brush head, an outer tube, a sliding ring and a hand ring, wherein the brush head comprises a brush handle and bristles, the outer tube is a strip-shaped hollow tubular structure, a through hole is arranged in the sliding ring, the tail part of the outer tube is fixed at the position of the through hole in the sliding ring, and the hollow tubular structure of the outer tube is communicated with the through hole in the sliding ring; the brush head is inserted in the outer tube, the head of the brush handle extends out of the outer side of the head of the outer tube, and the brush bristles are fixed at the head of the brush handle; the brush handle penetrates through the through holes in the outer tube and the sliding ring to be fixedly connected with the hand ring; the brush hair is fixed towards the head of the brush handle in an inclined way.

Furthermore, the number of the brush hairs is multiple, and the brush hairs are uniformly fixed on the head of the brush handle.

Further, the plurality of bristles are uniformly arranged along the axial direction and the radial direction of the brush holder head, and the plurality of bristles are arranged in parallel with each other.

Furthermore, the included angle alpha between the bristles and the brush handle is 40-60 degrees.

Further, α is 45 °.

Further, the diameter of the brush handle is A, the diameter of the outer tube is B, the length of the bristles is L, and then L is (1-1.5) B is (3-4) A.

Further, L ═ 1.2B ═ 3.6A.

When the disposable cell brush is used, the working process is as follows: the outer tube is inserted into an endoscope channel and enters a patient body, the hand ring is controlled, the hand ring is pushed or pulled, the hand ring is controlled to move forwards or backwards, the brush head can be extended and retracted, bristles inclined towards the head of the brush handle pierce cells and brush pathological tissue mucus, and sampling can be carried out; after the sample was accomplished, the pulling bracelet, the brush head is retreated and is got into in the outer tube, takes out the outer tube from the endoscope pincers way again, then promotes the bracelet, and the brush head stretches out the outer tube outside, puts into check out test set with the sample that takes out, accomplishes whole sampling process promptly.

Compared with the prior product, the utility model discloses a disposable cell brush of brush hair slope has following advantage:

(1) the bristles in the disposable cell brush incline towards the head of the brush handle and fall forward, and when the bristles extend out of the outer tube, the fallen bristles have a certain puncture effect, so that more pathological tissue mucus can be brushed, and sampling is facilitated;

(2) compared with the conventional vertical bristles, the bristles which are obliquely arranged towards the head of the brush handle in the disposable cell brush are not easy to deform, so that the diameter of the bristles is not easy to change, and the sampling effect is better;

(3) the disposable cell brush limits the included angle between the brush hair and the brush handle, limits the relation among the diameter of the brush handle, the diameter of the outer tube and the length of the brush hair, and can sample more pertinently;

(4) the disposable cell brush has the advantages of simple design, low production cost and easy realization.

Detailed Description

The technical solution of the present invention will be explained in detail by the following embodiments.

Example 1

As shown in figures 1-3, the whole structure and partial connection structure of the disposable cell brush with inclined bristles are schematically shown.

The disposable cytobrush with inclined bristles comprises a brush head 1, an outer tube 2, a sliding ring 3 and a bracelet 4, wherein the brush head 1 comprises a brush handle 11 and bristles 12, the outer tube 2 is a long-strip-shaped hollow tubular structure, a through hole is formed in the sliding ring 3, the tail part of the outer tube 2 is fixed at the position of the through hole in the sliding ring 3, and the hollow tubular structure of the outer tube 2 is communicated with the through hole in the sliding ring 3; the brush head 1 is inserted into the outer tube 2, the head of the brush handle 11 extends out of the outer side of the head of the outer tube 2, and the brush handle 11 penetrates through holes in the outer tube 2 and the slip ring 3 to be fixedly connected with the hand ring 4;
