Description

Puncture assisting device and puncture method

Technical Field

The invention relates to the field of medical instruments, in particular to a puncture auxiliary device and a puncture method.

Background

With the development of medical technology, the minimally invasive diagnosis and treatment under the guidance of CT is more and more widely applied, the key of the diagnosis and treatment technology is accurate puncture, the accurate puncture mainly relates to the angle, the layer and the depth of a puncture needle, and the angle and the layer are factors which are difficult to control, so the main factors influencing the puncture accuracy are the needle insertion angle and the needle insertion layer of the puncture needle. At present, most hospitals operate by hands according to experience, and because the needle inserting angle of the puncture needle is a three-dimensional space angle, the success rate of simple experience operation is low, repeated adjustment is needed, the operation time is prolonged, and meanwhile, the pain and the operation risk of patients are increased.

At present, a relatively precise operation mode is to adopt laser to position, however, a base for fixing the laser must be arranged at the tail part of a CT machine tool, the long axis of the base is parallel to the short axis of a CT scanning bed, the projection of a word line of the laser must be vertical to the plane vertical to the horizontal plane of the CT machine, a support frame is slid to a proper position, the laser is opened and rotated, the real-time display data of a display is matched with the angle data measured according to the CT, the needle insertion route preset before an operation is determined to be consistent with that of the operator, then a doctor holds a puncture needle to insert the needle along the word light mark line of the laser, and the puncture needle can be inserted into a focus according to a preset needle path. Secondly, the light source of the laser is emitted from the head side or foot side of the patient, and the head of the surgical facility, equipment, or the surgeon or physician's assistant is easily shielded from the projection of the linear laser beam due to the need to look down during the surgery, and the laser projection line cannot be projected to the surgical field, and the positioning function is completely lost.

Simultaneously, in the operation process of puncture under the CT guide, confirm needle insertion point and needle insertion angle back through the CT machine, the human body comes out from the CT machine and performs the operation, because this in-process patient moves the health, the human body breathes or the quivering of operator's hand, all can take place body surface puncture point and guide laser line can not coincide, or other reasons cause sheltering from of laser line, can't throw to the operation region, cause laser guide equipment to lose the guiding action, at this moment, must rely on operating doctor's experience bare-handed completion puncture operation, bring more misery for patient, increased the operation risk, and is inconvenient, and low work efficiency.

Disclosure of Invention

The invention mainly aims to provide a puncture auxiliary device and a puncture method, so as to solve the technical problem that in the related art, a puncture position is changed due to the fact that a conventional laser guide device is easy to shield or slightly change the position of a patient in the operation process, and the puncture point cannot be accurately positioned.
