Fixing device capable of precisely feeding catheter during surgery and working method thereof

Abstract

The invention relates to a fixing device capable of precisely feeding a catheter during surgery and a working method thereof, and belongs to the field of medical instruments. The fixing device comprises a base, guiding holes are formed in the base, the guiding holes are internally matched with guiding rods, a shelf is fixed to the tops of the guiding rods, a lifting air bag is arranged between theshelf and the base and connected with a power air bag through an air guiding pipe, a one-way valve is arranged on the joint of the lifting air bag and the air guiding pipe, an air releasing valve isarranged on the lifting air bag, stopping blocks are fixed to the bottoms of the guiding rods, the guiding rods are sleeved with lifting springs, and the lifting springs are located between the stopping blocks and the base. By means of the fixing device, the catheter can be properly lifted up according to the surgical condition, so that air is prevented from entering a human body to cause air embolism; the catheter can be quantificationally and precisely fed according to the surgical condition, so that the surgical effect is guaranteed.

Description

technical field [0001] The invention relates to an intraoperative catheter fixing device capable of precise feeding and a working method thereof, belonging to the field of medical devices. Background technique [0002] Intervention 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 to diagnose and locally treat pathological conditions in the body. [0003] 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. Diseases that require surgical treatment or medical treatment are not effective, such as tumors, hemangiomas, various hemorrh...

AI Technical Summary

Problems solved by technology

[0004] When the catheter is introduced into the human body, the position of its end changes with the continuous introduction of the catheter. When the level of the catheter end is greater than the catheter behind the catheter end, the air bubbles in it will easily enter the human body under the action of buoyancy, so that It will endanger the health of the patient, especially in the interventional operation of the blood vessel, and even endanger the life of the patient

During the introduction of the catheter into the human body, the catheter is generally fed manually by a doctor, but manual feeding has the problem of inaccurate feeding
