Puncture positioning device for department of cardiology

Abstract

The invention provides a cardiology department puncture positioning device which comprises a supporting frame, a puncture positioning piece is arranged on the supporting frame and comprises a frame body, a skin fixing piece, a puncture outfit clamping piece and the like, and the frame body comprises a plurality of guide rods; the skin fixing part is used for fixing the skin of the puncture part; the skin fixing part comprises a C-shaped silica gel ring, a flexible shaft connected with the silica gel ring into a whole is arranged in the silica gel ring in the moving direction of the silica gel ring, one end of the flexible shaft extends out of the silica gel ring and is connected with an output shaft of a stepping motor, the stepping motor is connected with a motor controller, a plurality of bearings are further arranged in the silica gel ring, the flexible shaft sequentially penetrates through inner rings of the bearings, and the motor controller is connected with the motor controller. The outer ring of each bearing is fixedly connected with one end of a rod body, and each rod body penetrates out of the silica gel ring and then is fixedly connected with each guide rod in a one-to-one correspondence manner; the puncture outfit clamping piece is connected with the guide rod in a sliding mode. Accurate puncture positioning can be achieved, and puncture operation can be stably implemented.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a puncture positioning device for cardiology. Background technique [0002] Puncture is a common operation in medical technology. It is a diagnosis and treatment technique that pierces a puncture needle into a body cavity to extract secretions for testing, injects gas or contrast agent into the body cavity for angiography, or injects drugs into the body cavity. It is widely used in cardiology. In the treatment of diseases in hospital departments. In the prior art puncture operation, if the doctor's technique is not skilled, it is easy to cause the puncture to be inclined, especially the human skin has a certain elasticity, and it is easy to slip during the puncture, resulting in inaccurate puncture. At times, the doctor needs to use the thumb and index finger of one hand to press the skin at the puncture site and flatten the skin, so that the puncture needle of the puncture de...

AI Technical Summary

Problems solved by technology

In the puncture operation of the prior art, if the doctor is unskilled in the puncture operation, the puncture is likely to be tilted, especially the human skin has a certain degree of elasticity, and it is easy to slip during the puncture, resulting in inaccurate puncture. Sometimes, the doctor needs to use the thumb and forefinger of one hand to press the skin at the puncture site and flatten the skin so that the puncture needle of the puncture device held by the other hand can stably penetrate the skin. Occupying the doctor's two hands at the same time makes it difficult for the doctor to perform the puncture operation stably, and the puncture process is often too dependent on the doctor's experience, which increases the risk of inaccurate puncture positioning or even puncture failure
