Puncture rack and adjusting block applied to puncture rack

Abstract

The embodiment of the invention discloses a puncture rack and an adjusting block applied to the puncture rack. Two sides of the puncture rack can be simultaneously matched with at least two adjustingblocks for simultaneous use, the puncture rack comprises needle feeding structures arranged on two sides of a needle feeding plane of the puncture rack and the adjusting blocks 1 installed on the needle feeding structures, wherein needle slots 3 for puncture needles to pass through are formed between the needle feeding structures and the adjusting blocks. The needle feeding structures and the adjusting blocks matched with the needle feeding structures are arranged on the two sides of the needle feeding plane of the puncture rack respectively, accordingly the needle feeding side to be used canbe flexibly selected without B-mode ultrasound probe turning according to the demand of a needle feeding route during a puncture operation performed by a doctor, the operation complexity can be reduced, and thus operation inconvenience can be avoided without standing position adjustment. Multiple different specifications are provided for the adjusting blocks, adaptive adjustment on the walls of the adjusting blocks can be performed according to the diameters of puncture needles, and accordingly the puncture rack can adapt to difference specifications of puncture needles in puncture operation.

Description

technical field [0001] The invention relates to the technical field of ultrasonic B-ultrasound puncture surgical tools, in particular to a puncture frame capable of inserting needles from both sides and an adjustment block applied thereto. Background technique [0002] Puncture frame, also known as ultrasound probe puncture frame, or puncture guide frame, or puncture guide. By installing a puncture frame on the ultrasound probe, the puncture needle can be guided to the target position of the human body under the guidance of ultrasound to achieve cytological biopsy, histological biopsy, cyst aspiration and treatment, etc. When using the puncture rack for needle insertion control, perform needle insertion according to the direction indicated by the probe. [0003] The commonly used B-ultrasound probe has a prompting mark on the prompting side for needle insertion. Correspondingly, the puncture frame in the prior art will be designed as a single-side needle insertion structure...

AI Technical Summary

Problems solved by technology

[0005] In view of this, in order to solve the technical defect in the prior art that the doctor's operation is complicated when adjusting the needle insertion direction, the present invention provides a puncture frame and an adjustment block that can insert needles from both sides with a simple structure and convenient installation and disassembly; the puncture frame It can realize the doctor's one-handed operation, quickly switch the puncture direction (the left side of the probe or the right side), and reduce the difficulty of the doctor's operation and the time required for the operation during the puncture operation
