Description

Integrated medical bone marrow biopsy needle

Technical field:

The utility model relates to a bone marrow puncture biopsy needle, in particular to an integrated medical bone marrow puncture biopsy needle device.

Background technique:

At present, the clinical diagnosis of many blood tumors and other diseases requires bone marrow aspiration and bone marrow biopsy. Bone marrow aspiration needle and bone marrow biopsy needle are necessary instruments for bone marrow aspiration and bone marrow biopsy. Existing technology, generally first carries out bone marrow aspiration with bone marrow puncture needle, then carries out bone marrow biopsy with bone marrow biopsy needle at a certain distance. On the one hand, there are many steps in the entire operation process, and the operation time is long, which causes the patient's local tissue damage and bleeding twice, increases the patient's local pain, makes the patient's poor compliance with the operation, and directly affects whether the entire operation process can be carried out smoothly and The quality of the specimens taken is good or bad. On the other hand, since the bone marrow aspiration and bone marrow biopsy are performed successively at a certain time interval, it is very easy to cause the quality of the surgical specimens performed later to be poor, and clots and dilutions to occur.

Invention content:

The purpose of the utility model is to provide an integrated medical bone marrow puncture biopsy needle, which can effectively solve many problems in the prior art, such as many operation steps, long operation time, much pain for patients, and difficulty in guaranteeing the quality of specimens.

The utility model integrated medical bone marrow puncture biopsy needle is realized by the following technical scheme, which is composed of a puncture biopsy needle tube, a puncture biopsy needle handle, a sealing plug, a puncture needle core, a biopsy needle core, a puncture needle core handle and a biopsy needle Core handle construction. The puncture biopsy needle tube is provided with a biopsy needle tube, and the front end of the biopsy needle tube is in the shape of a sharp shovel. The biopsy needle tube is thin in front and thick in back. The front end of the puncture biopsy needle tube is provided with a scale line. An injection port is provided on the puncture biopsy handle. The syringe interface is provided with a sealing plug. A positioning bayonet is provided at the joint between the puncture biopsy needle handle and the sealing plug. A positioning bayonet is provided at the joint between the puncture biopsy needle handle and the puncture needle core handle. A positioning bayonet is provided at the joint between the handle of the puncture biopsy needle and the handle of the core of the biopsy needle.

The utility model can complete puncture and biopsy at one time, effectively reduce the operation process, and can limit the damage of puncture and biopsy to one point, thereby effectively reducing tissue damage and bleeding, reducing the pain of patients, and improving the quality of obtained samples. It is widely used in It is a device for clinically testing patients' bone marrow aspiration and bone marrow biopsy at the same time.

Description of drawings:

The integrated medical bone marrow puncture biopsy needle of the utility model will be further described in detail in conjunction with the accompanying drawings.

Accompanying drawing 1 is the structural representation of the utility model.

Accompanying drawing 2 is the structural representation of removing the core of the biopsy needle and adding the sealing plug of the utility model.

Detailed ways

Referring to the accompanying drawings, the embodiment of the integrated medical bone marrow biopsy needle of the present invention is composed of a biopsy needle tube 1, a biopsy needle handle 2, a puncture needle core handle 3, a puncture needle core 4, and a biopsy needle core 5 , biopsy needle core handle 6 and sealing plug 7 constitute. Put the puncture needle core 4 with the puncture needle core handle 3 and the biopsy needle core 5 with the biopsy needle core handle 6 in the puncture biopsy needle tube 1 with the puncture biopsy needle handle 2, the front end of the puncture biopsy needle tube is provided with The scale line, the front end of the biopsy needle is sharp spatula. The biopsy needle tube is thin at the front and thick at the back. The needle core 5 of the biopsy needle is inserted into the muscle to the periosteum and then pulled out. The sealing plug 7 is fixed with the handle 2 of the biopsy needle, and then inserted into the bone marrow cavity, and the bone marrow tissue is taken out in the biopsy needle tube. , the needle core 4 of the puncture needle is extracted, and the bone marrow fluid can be extracted.
