Description

A fixed head frame for interventional surgery

technical field

The utility model relates to the technical field of medical instruments, in particular to a fixed head frame for interventional operations.

Background technique

Interventional therapy is a kind of minimally invasive treatment using modern high-tech means—that is, under the guidance of medical imaging equipment, special catheters, guide wires and other precision instruments are introduced into the human body for diagnosis and local treatment of pathological conditions in the body. Intervention therapy uses digital technology to expand the doctor's field of vision. With the help of the catheter, the guide wire extends the doctor's hands. Its incision (puncture point) is only the size of a grain of rice. It can treat many diseases that could not be treated in the past without cutting human tissue. For diseases that require surgical treatment or medical treatment with poor efficacy, such as tumors, hemangiomas, and various hemorrhages, interventional treatment has the characteristics of no surgery, small trauma, fast recovery, and good results. It is the development trend of future medicine.

In interventional surgery, it is often necessary to fix the patient's head and neck with the help of a head frame, so that doctors can introduce special catheters, guide wires or other precision instruments into the body. In the neck, it is easy to bring discomfort to the patient and affect the patient's surgical mood. Often after the interventional operation, the head and neck will experience obvious soreness, which is not good for the treatment of the patient.
