Embodiment Construction

[0020] Such as figure 1 and 2 as shown, figure 1 It is a structural schematic diagram of a puncture auxiliary guide bracket proposed by the present invention, figure 2 It is a structural schematic diagram of a positioning mechanism of a puncture auxiliary guide bracket proposed by the present invention.

[0021] refer to figure 1 , a puncture auxiliary guide bracket proposed by the present invention, comprising: a bracket body and a positioning mechanism;

[0022] The main body of the bracket includes a bracket base 1 and a mounting frame body. The bracket base 1 is provided with a slide rail 2, and the slide rail 2 is provided with a slide seat 3 which can be slidably installed. The end of the frame body away from the sliding seat 3 is provided with a needle insertion guide 5 on the positioning mechanism.

[0023] In the specific working process of the puncture auxiliary guide bracket of this embodiment, during use, the needle insertion direction of the puncture is adju...

Abstract

The invention discloses a puncture assisting guide support. A support body comprises a support seat and a mounting frame, a slide rail is arranged on the support seat, a sliding seat is mounted on theslide rail in a sliding manner, the mounting frame is mounted on the sliding seat, a positioning mechanism is mounted at one end, away from the sliding seat, of the mounting frame, and a puncture guide part is arranged on the positioning mechanism. By optimized design of the puncture assisting guide support and guide of needle enter direction of puncture by the positioning mechanism, the punctureaccuracy and stability are improved, meanwhile, the positioning mechanism is mounted on the support seat through the mounting frame in a sliding manner, the relative position of the positioning mechanism slides in a reciprocating manner with respiration of a patient to realize self-sliding position adjustment of the puncture needle with respiration of the patient and play a respiratory gating role, the positioning mechanism cannot cause traction to free respiration of the patient, and meanwhile, secondary injury caused by the respiratory puncture needle to organs is avoided in the puncture process.

Description

technical field [0001] The invention relates to the technical field of clinical medicine, in particular to a puncture auxiliary guiding bracket. Background technique [0002] In recent years, minimally invasive techniques have been rapidly developed and popularized, and a considerable part of the work is puncture of deep tissue targets under CT. Unlike puncture under B-ultrasound or DSA (Digital subtraction angiography), puncture under CT cannot be performed under real-time dynamic observation, and often requires multiple adjustments, which takes a long time and has large errors. [0003] In the prior art, usually the medical staff punctures completely with bare hands. After clarifying the puncture point on the body surface, they estimate the angle and depth of the needle insertion based on experience. With the improvement of puncture accuracy requirements, ordinary protractors are also used for positioning. This positioning method requires assistants to use a protractor to...
