Description

Bone marrow puncture needle

Technical Field

The utility model belongs to the technical field of medical appliances, concretely relates to marrow puncture needle.

Background

For patients with blood system diseases such as leukemia, a bone marrow puncture is required for accurate diagnosis. The main body of the prior bone marrow puncture needle used clinically is mainly a needle cylinder and a needle body, and the needle body can axially slide in the needle cylinder. The puncture needle has the advantages of simple structure and low cost, but the puncture needle can be operated by only one hand due to the short size, which causes poor stability, easy deviation, inconvenient operation of operators, laborious operation process and the like.

Along with the improvement of the living standard of people, the self-care consciousness of people is gradually improved, the comfort and the safety of medical operation are higher required, and the traditional bone marrow puncture needle is difficult to meet the requirements due to the defects of poor stability, easy deviation, inconvenient operation, labor-consuming operation process and the like.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, the present invention provides a bone marrow puncture needle. The device has good stability and comfortable size, can be operated by two hands, saves labor in the operation process, improves the comfort and safety of operation, and has simple structure and low cost.

The utility model discloses the technical scheme who adopts does:

the bone marrow puncture needle comprises a stabilizer and a bone marrow puncture needle with a needle handle, wherein the stabilizer is provided with a transparent stable cover, a soft non-slip pad, a needle sleeve and a cross needle sleeve fixer, the upper part of the needle sleeve is connected and fixed with the transparent stable cover, the tail end of the needle sleeve is connected with the cross needle sleeve fixer, and the bone marrow puncture needle is provided with a needle body, a needle core, a core taking handle and a needle handle.

The stabilizer main body is a transparent stabilizing cover, the bottom of the stabilizer main body is connected with a soft non-slip mat, the center of the stabilizer main body is rigidly connected with a needle sleeve, the outside of the needle sleeve is rigidly connected with a cross-shaped needle sleeve fixer, and the parts cannot move relatively.

When the bone marrow puncture needle is inserted into the needle sleeve, the needle body can slide axially in the needle sleeve.

The head of the needle body is frustum-shaped and hollow, the head of the needle core is a cone-shaped body, the diameter of the cone-shaped body is the same as that of the frustum at the head of the needle body, the cone-shaped body penetrates out of the frustum, and the tail of the needle body is rigidly connected with the needle handle and cannot move relatively.

The needle core is inserted into the needle body and can axially slide in the inner wall of the needle body.

The tail part of the needle core is rigidly connected with a core taking handle, the needle core can be taken out along the core taking handle, and the core taking handle can be placed in the needle handle.

The beneficial effects of the utility model are that:

the utility model discloses an operating stability is good, and the size is comfortable, but both hands operation and comparatively laborsaving, reduced uncomfortable sense of patient, improved security, the operating efficiency of operation.

Detailed Description

The following describes the present invention with reference to the accompanying drawings.

As shown in figure 1, the utility model discloses divide into stabilizer 1 and take the marrow pjncture needle 2 of needle handle, aim at the implementation position earlier with the stabilizer and fix during the use, insert the needle cover with the marrow pjncture needle, fix the stabilizer on one hand, the other hand is held and is treated the needle handle, and the vertical rotation pierces the puncture position, treats that the needle body gets into the marrow cavity after, takes the needle core out from getting core handle department, takes a syringe to extract appropriate amount marrow liquid and carries out examinations such as smear, cultivation.
