Problems solved by technology

In the prior art, the puncture needle is generally used for direct puncture, and the direction of the needle in the soft tissue is prone to deflection. It is difficult to control the puncture point and direction, and the number of operations increases, causing patients to suffer and reducing work efficiency
When the tissue is soft or the surface of the tissue is irregular, the operator performs puncture according to subjective experience, the above problems are more obvious, and seriously affect the diagnosis and treatment effect

Abstract

The present invention discloses a bidirectional orbicular puncture localizer, comprising an orbicular matrix which is provided with a positioning hole or a slot which passes through a ball center. According to the characteristic that the orbicular matrix can be put or embedded inside the irregular position, the present invention can be used for positioning when the quite soft tissue and the irregular tissue are punctured. The orbicular matrix is provided with the positioning hole or slot, which is convenient for using. A needle penetrating hole or a slot can fix a puncture needle at the head, the feet and the left and right directions during the process of puncturing to avoid the directional deviation.

Description

technical field [0001] The invention relates to a puncture medical device, in particular to a bidirectional spherical puncture positioner. Background technique [0002] Puncture is a means of biopsy and disease treatment. For example, percutaneous biopsy is to reach the lesion area for biopsy and particle implantation through percutaneous puncture, and it is to reach the lesion area for treatment through percutaneous puncture. On the one hand, it is used for the diagnosis of diseases, and on the other hand, it injects drugs and places instruments through puncture for treatment. During the puncture process, the puncture needle is used to penetrate into the diseased tissue for collecting specimens and establishing a working channel. In the prior art, puncture needles are generally used for direct puncture, which is prone to deflection of the needle direction in the soft tissue. It is difficult to control the puncture point and direction, and the number of operations increases...
