Infusion port catheter cutting protection sheath and device

Abstract

The invention provides an infusion port catheter cutting protection sheath and device, and aims to avoid uncertain risk increase caused by manual surgical operation, prevent a surgical blade from damaging a catheter and improve surgical safety and operation efficiency. The infusion port catheter cutting protection sheath is made of a metal sheet and is divided into an upper section, a middle section and a lower section in the axial direction. The middle section and the lower section integrally form a cylindrical sheath body with a notch in one side; the inner diameter of the sheath body is matched with the outer diameter of the catheter to be protected; the requirement that the protection sheath is attached to the catheter is met; and meanwhile the protection sheath can naturally slide down along the catheter to be protected under gravity. The upper section is in a strip shape, is axially connected to the other side, corresponding to the notch, of the upper end of the middle section, and tilts in the direction away from the axis of the sheath body. The middle section is an annular belt with a notch in one side. From a sheath ring to a sheath tail wing, the edges of the corresponding notches are in arc transition.

Description

technical field [0001] The present application mainly relates to a device for protecting catheters during operation in clinical treatment (such as peritoneal perfusion treatment). Background technique [0002] Peritoneal perfusion therapy is one of the more commonly used treatment methods in the medical field. Venous port abdominal wall implantation is a new technology application of peritoneal perfusion therapy. The device is easy to operate repeatedly, reduces the number of abdominal puncture operations, avoids many inconveniences caused by activities with tubes, reduces pain and fear of patients, improves the quality of life of patients, and reduces the probability of abdominal infection. In addition, the implementation of this technology will simplify the operation of intraperitoneal infusion chemotherapy for front-line clinicians, improve work efficiency and safety of infusion chemotherapy, and it is a technical application that kills two birds with one stone. In the a...

Problems solved by technology

In the application of this technology, after the catheter is inserted into the abdominal cavity, a slope needs to be created in the subcutaneous tissue of the abdominal wall to prevent the catheter from forming a right angle and affecting the use. Care must be taken to avoid the catheter with the tip of the knife to prevent the blade from accidentally scratching the catheter and cause the operation to fail. This operation can only rely on the technique of the surgeon, and requires the operator to concentrate and avoid the catheter as much as possible. There are many uncertain factors, and accidents may occur. higher risk

[0003] In addition, in the practice operation of medical students, it is necessary to use the fixed device to repeatedly practice the operation. Catheter implantation is the basic operation technology at present. The risk of operation and the cost of teaching
