Problems solved by technology

The catheter in this part of the sleeve is prone to large bends, which can cause damage to the catheter in the worst case, and cannot meet the clinical use requirements of vascular interventional surgery robots
[0008] 3. Difficulty in disinfection and sterilization
The telescopic sleeve is a semi-closed part, and it is easy to contain tiny dust inside, which is difficult to completely eliminate
These dusts may adhere to the catheter and enter the blood, endangering the life and health of patients

Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] This embodiment provides an anti-bending device for catheters used in intravascular interventional surgery robots, see the attached figure 1 , including: fixed mount, push mount, spring 3, hose 6 and conduit 7;

[0029] See attached figure 2 , the through hole A for passing through the conduit 7 is processed on the fixed mounting seat; the fixed mounting seat is composed of two split modules butted, and the two split modules are respectively a fixed seat A1 and a fixed seat B2; the fixed An installation groove A for passing through the conduit 7 is processed on the seat A1. When the fixed seat A1 and the fixed seat B2 are butted together, the opening side of the installation groove A is closed by the fixed seat B2 to form the through hole A;

[0030] See attached image 3 , the push mounting seat is processed with a through hole B for passing th...

Abstract

The invention discloses a catheter in-vitro anti-bending device for an intravascular interventional surgical robot, and belongs to the technical field of surgical robots. The catheter in-vitro anti-bending device comprises a fixed mounting seat, a push mounting seat, a spring, a hose and a catheter, wherein the fixed mounting seat is fixed on a surgical robot, one end of the hose is fixed in the through hole A of the fixed mounting seat, the other end of the hose penetrates through the through hole B of the push mounting seat and then is connected with an external tensioning mechanism, the spring is sleeved outside the hose in a linear tightening state, the two ends of the spring are fixedly connected with the fixed mounting seat and the push mounting seat respectively, the catheter penetrates through the hose, the two ends of the catheter extend out of the hose, the head of the catheter is fixedly connected with the push mounting seat through a pull rod, and the tail of the catheter extends out of the fixed mounting seat. According to the invention, he device can prevent the catheter from being bent due to resistance during in-vitro environment delivery so as to achieve the axialsafe pushing of the catheter.

Description

technical field [0001] The invention belongs to the technical field of surgical robots, and in particular relates to an anti-bending device outside the body of a catheter used for an interventional surgical robot in a blood vessel cavity. Background technique [0002] Endovascular technology has become the basic means of vascular treatment, and most of the vascular reconstruction operations currently performed require the help of this technology. Guide wire-catheter operation is the core content of endovascular technology and determines the quality of surgery. At present, clinical doctors use digital silhouette angiography (DSA) to manually complete the positioning operation of the guide wire-catheter in the patient's blood vessel. Conventional passive guide wires, guiding catheters, and balloon catheters are the basic instruments used in surgery. The use of robotic devices for guide wire (catheter or other instruments, the same below) positioning operation is conducive to...
