passive surgical instrument endoscope spray catheter is an injection spray tube used for endoscopic surgery, which has the following characteristics and composition.
Features:
1. Passive surgical instruments are instruments that do not require external energy supply and can be operated directly through an endoscope, reducing the complexity and dependence of the surgical process.
2. The injection spray tube has a smaller outer diameter and can enter the human body through a smaller incision, reducing surgical trauma and pain.
3. The injection spray tube has good flexibility and operability, and can flexibly adjust the angle and direction during the surgical process, improving the accuracy and safety of the surgery.
4. The injection spray pipe has good biocompatibility and corrosion resistance, and can be used for a long time without causing infection or damage.
Composition:
Passive surgical instruments endoscope spray catheter mainly consist of injection spray tubes and connectors. Injection spray pipes are usually made of high-strength medical stainless steel or high-strength plastic, which have good pressure resistance and wear resistance. Connectors are usually made of medical silicone or other high-temperature and corrosion-resistant materials, used to connect injection spray tubes and endoscopes.
Type:
According to different surgical requirements, the injection spray tubes of passive surgical instruments can be classified into different types. Common types include straight, curved, and rotating. Linear injection spray tubes are suitable for linear injection and spraying operations, curved injection spray tubes are suitable for surgeries that require operation in curved channels, and rotary injection spray tubes are suitable for surgeries that require rotation operations.
In summary, the endoscope spray catheter of passive surgical instruments is an important tool for endoscopic surgery, characterized by no external energy supply, small incisions, flexible operation, and good biocompatibility. According to the different surgical requirements, different types of injection spray tubes can be selected for operation.
