Bullet-nosed detachable adaptive puncturing locating mould plate

Abstract

A detachable type shape-adapted puncture positioning mould board is disclosed in the present invention, comprising at least two substrates, the substrates comprise side face, upper plane and lower plane, the substrates are provided with at least one permeation needle holes, the permeation needle holes of different substrates are parallel mutually; the at least two substrates assort with up and down slidable horizontal fixing mode, the present invention can fix the puncture needle horizontal position during puncturing course, avoid bending, deviating direction and skidding, expanding the mouldboard using range, at the same time, can ensure a plurality of puncture needles are parallel mutually; each substrate can slide up and down, ensure the needle holes are parallel at the same time, canbe suitable for irregular tissue surface puncture.

Description

Detachable conformal puncture positioning template technical field The invention relates to a medical instrument for puncture, in particular to a detachable conformal puncture positioning template. Background technique Puncture is a means of biopsy and treatment of diseases. For example, percutaneous biopsy is to reach the lesion area for biopsy by percutaneous puncture, and seed implantation is to reach the lesion area for treatment by 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 surface of the tissue for collecting specimens and establishing a working channel. In the prior art, puncture needles are generally used for direct puncture. When the surface of the punctured tissue is relatively hard (such as bone), it is prone to slipping. It is difficult to control the...

AI Technical Summary

Problems solved by technology

In the absence of a positioning device, it is not only difficult to ensure uniform distribution of multiple needles, it is even more difficult to ensure parallel

Similarly, the same problem exists when biopsy specimens need to be taken simultaneously in a small area

Especially in the case of small needle distance, this shortcoming is particularly obvious, which seriously affects the treatment effect
