Description

Brain glioma tissue extraction element

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to brain glioma tissue extraction element.

Background

Tumors derived from neuroepithelia are collectively called brain gliomas, account for 40% -50% of craniocerebral tumors, are the most common intracranial malignant tumors, and have an annual incidence of 3-8 persons/10 ten thousand of people. Symptoms and signs caused by brain glioma are mainly determined by the space occupying effect and the affected brain area function. Due to the space occupying effect of glioma, the patient can have symptoms of headache, nausea, vomiting, epilepsy, blurred vision and the like.

At present, the treatment methods of brain glioma mainly comprise radiotherapy, chemotherapy and operation. In the process of surgical treatment, an extraction device is needed to extract the brain glioma and the peripheral lesion tissues firstly, and then other steps are carried out. Currently, there are many structural devices for extracting brain glioma, which are commonly used in the art, however, the common problems of these devices are: the structural design is relatively complex, the operation process is complex, and in addition, the extraction effect is not particularly good.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple structure, convenient operation, draw fast, draw effectual brain glioma tissue extraction element.

The utility model discloses a solve the technical scheme that technical problem adopted as follows:

the utility model discloses a brain glioma tissue extraction element, include:

a needle-shaped tube;

a fixed rod fixed at the rear end of the needle-shaped pipe;

an extractor mounted inside the needle tube;

the extractor comprises a threaded rod, an ellipsoidal head arranged at the front end of the threaded rod and an installation rod arranged at the rear end of the threaded rod.

Further, the maximum pipe diameter of the needle-shaped pipe is 3mm or 4 mm.

Furthermore, the end of the fixing rod is spherical, the spherical end is an opening, and the inside of the fixing rod is of a hollow structure.

Further, the mounting rod is located in the hollow structure inside the fixing rod and extends out of the spherical opening.

Further, a part of the ellipsoidal head is exposed out of the needle-shaped pipe.

The utility model has the advantages that:

1. the utility model discloses in, will draw the head to design into the ellipsoid shape, can effectually reduce pathological tissue's damage, keep pathological tissue's integrality, improve subsequent detection precision.

2. The utility model discloses in, will draw the main part and design into the screw thread form, draw pathological mechanism through the screw thread, not only convenient but also swift.

3. The needle-shaped tube can prevent the extracted pathological tissues from sliding off, improve the extraction efficiency and avoid secondary extraction.

4. The biggest pipe diameter of needle-shaped pipe is 3mm or 4mm, can more effectual reduction to the damage of brain tissue, makes the extraction process safe and reliable more.

Drawings

Fig. 1 is a schematic structural view of the device for extracting brain glioma tissue of the present invention.

In the figure: 1. an ellipsoidal head, 2, a needle-shaped pipe, 3, a threaded rod, 4, an installation rod, 5 and a fixing rod.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, the utility model discloses a brain glioma tissue extraction element mainly includes: an ellipsoidal head 1, a needle-shaped pipe 2, a threaded rod 3, an installation rod 4 and a fixing rod 5.

The fixing rod 5 is fixed at the rear end of the needle-shaped pipe 2, the end part of the fixing rod 5 is spherical, an opening is formed in the spherical end, and the fixing rod 5 is of a hollow structure. The fixing rod 5 is used for being fixedly connected with external detection control equipment.

The extractor is composed of an ellipsoidal head 1, a threaded rod 3 and a mounting rod 4. The ellipsoidal head 1 is fixed at the front end of the threaded rod 3, and the mounting rod 4 is fixed at the rear end of the threaded rod 3. The mounting rod 4 is used for connecting with an external detection control device.

The extractor is integrally mounted inside the needle tube 2. Specifically, an ellipsoidal head 1 and a threaded rod 3 are installed inside a needle-shaped tube 2, a part of the ellipsoidal head 1 is exposed outside the needle-shaped tube 2, and a mounting rod 4 is installed in a hollow structure inside a fixing rod 5, and the end of the mounting rod 4 protrudes out of a spherical end opening.

The utility model discloses when in-service use, install extraction element externally on detecting controlgear (existing equipment), remove through drive installation pole 4, drive threaded rod 3 and ellipsoid head 1 and enter into brain glioma tissue region, then extract installation pole 4, at this moment, will be stained with brain glioma pathological tissue on the threaded rod 3, accomplish pathological tissue's extraction.

In the present embodiment, the maximum tube diameter of the needle-shaped tube 2 is 3mm or 4 mm.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
