GUIDE WIRE CATHETER DELIVERY DEVICE

Description

TECHNICAL FIELD

[0001] The present invention relates to the field of medical devices and particularly to a guidewire catheter delivery device.BACKGROUND TECHNOLOGY

[0002] As a very mature endoscopic minimally invasive technique in the treatment of diseases of the biliary pancreatic system, endoscopic retrograde cholangiopancreatography (ERCP) can be used to diagnose and treat gallstones, biliary obstruction, cholangitis, biliary tumors, pancreatic tumors, and the like. During the operation, a duodenoscope is inserted into the descending part of the duodenum of the patient, an angiographic catheter is inserted into the biopsy tube to reach the duodenal papilla opening, and then contrast agent is injected. The specific pancreaticobiliary conditions are observed under the X-ray film to determine whether there were lesions, and then the corresponding operation is carried out. ERCP has the advantages of less trauma, short operation time, few complications, and high safety. ERCP, as minimally invasive surgery, just causes a small surgical trauma, does not bring too much pain to the patient, and has fast postoperative recovery, but it needs to be done with the aid of X-rays, and the doctor for this surgery must be exposed to X-rays for a long time. Therefore, in order to improve the working environment of the doctors for interventional surgery, ERCP surgical robots have been developed in engineering to substitute doctors and complete surgery. As a result, doctors control ERCP surgical robots to complete surgery in an X-ray free environment through remote operation or remote control. At present, there is no effective and similar technical solution on the market.

[0003] At present, ERCP operations in China are performed manually by doctors and their teams. During the operation, the operators need to wear heavy anti-radiation suits, but the arm part must be exposed for operation, which cannot be protected against radiation. Long-term surgical radiation can cause serious radiation damage to the operators. In addition, the existing ERCP operation requires a lot of operators and cooperators, so it is crowded in the space-limited operating room. Doctors and operators need to stand all day long for surgery, which causes high-intensity work, and it is easy to fatigue and thus affect the accuracy of surgery and even lead to mistakes. Additionally, during the operation, it is difficult for the doctors and the operators to ensure that the hand does not shake, so the displacement may occur after the inserted human instrument is positioned.

The driven wheel frame 105 and the driven wheel 104 are assembled by the screw 108 and the nut 109 to translate within the main body 101. When the guidewire catheter 3 moves forward and backward, the motor support frame 201 tends to swing, which sequentially generates a pulling force or pressing force on the force sensor 202 installed at the bottom. The force sensor 202 at the bottom includes one end connected to the motor support frame 201, and the other end connected to the fixed seat 205 to ensure that the pulling force or pressing force can be generated.
