Introduction of Medical Cannulated Drill

Cannulated Drill Materials

Stainless steel: Stainless steel is a common material used in medical devices. Its excellent corrosion resistance and mechanical properties make it suitable for surgical instrument manufacturing. In medical core drills, stainless steel is typically used for the outer housing and handle.

Tungsten carbide: Tungsten carbide is a hard alloy commonly used in cutting components of medical devices, such as the tip of a medical core drill. Its high hardness and excellent wear resistance make it suitable for delicate cutting operations in orthopedic surgery.

Plastics/polymers: These materials are used in the handle and other non-cutting components of medical core drills. These materials are often chosen for their antimicrobial properties, ease of cleaning, and comfort, while also reducing the weight of the device.

Other Materials: Certain specialized medical core drill models may utilize other alloys or ceramics to meet specific surgical requirements or enhance device performance.

Features

Precision: Medical core drills are precision-engineered, providing a high degree of operational accuracy and control during surgery, enabling surgeons to perform delicate bone or tissue removal.

Clean Operation: Due to their hollow design, core drills help maintain a clean surgical field and rapidly expel cutting products, reducing congestion and interference during surgery.

Variety: Depending on surgical requirements, core drills are available with a variety of head sizes and shapes to accommodate different types of procedures and meet the needs of diverse surgical scenarios.

Bone Removal: Medical core drills are specifically designed for cutting and removing bone tissue, providing essential support and efficiency for orthopedic surgery.

Auxiliary Device Installation: In some procedures, core drills can also be used to create holes for the installation of internal fixation devices or other auxiliary devices.

Efficiency: Medical core drills use a rotary motion to efficiently cut and remove bone tissue, providing essential efficiency and accuracy.

Safety: Professionally designed and manufactured, core drills provide safe and reliable surgical procedures when used correctly.

Applications

Orthopedic Surgery: In orthopedic surgery, medical cannulated drills are commonly used for fracture reduction, bone graft fusion, and joint replacement procedures. They precisely cut and remove bone tissue, providing the necessary accuracy and control for the procedure.

Neurosurgery: In neurosurgery, medical cannulated drills are commonly used for procedures such as cranial drilling and removal of intracranial tumors or hematomas. Their precision and clean operation make them indispensable tools in neurosurgery.

Sampling and Puncture: Medical cannulated drills can also be used for sampling and puncture procedures. For example, in interventional oncology procedures, doctors may use cannulated drills to obtain tissue samples or administer therapeutic injections.

Cleaning and Preparing the Surgical Field: Due to their hollow design, medical cannulated drills help doctors clean the surgical field, remove bone tissue or other materials, and quickly expel cutting products, keeping the surgical field clean.

Device Installation: In some procedures, medical cannulated drills can also be used to create holes in appropriate locations for the installation of internal fixation devices or other auxiliary devices.

Cannulated drills play an important role in orthopedic and neurosurgery. Their precision and clean operation characteristics help improve the success rate of surgery and reduce patient trauma.

Instructions

Preparation: Before using a core drill, thoroughly clean and sterilize the instrument to ensure it meets hygienic standards. Also, inspect the instrument for integrity and select the appropriate core drill specifications and accessories based on the type of procedure.

Wearing Protective Equipment: The operator should wear appropriate personal protective equipment, including gloves, a mask, and goggles, to ensure safety during the procedure.

Positioning and Immobilization: Before the procedure, the patient's surgical site must be accurately positioned and immobilized to facilitate precise manipulation.

Procedure:

Grip the core drill handle and gently place the blade on the surgical site.

Start the core drill and begin cutting or removing bone tissue using a rotary motion.

Maintain a stable hand position throughout the procedure to ensure accurate and safe cutting.

Controlling Force and Speed: The operator must control the cutting force and rotational speed of the core drill according to the surgical requirements to avoid damaging surrounding tissue.

Monitoring: While using the core drill, the surgical area must be constantly monitored to ensure accurate and safe manipulation.

Cleaning and Maintenance: After surgery, the medical cannulated drill needs to be thoroughly cleaned and disinfected, and then properly stored for future use.

Precautions

Professional Operation: Medical core drills should be used by professionally trained medical personnel. Untrained or unqualified personnel are prohibited from operating medical core drills.

Instrument Inspection: Before use, the medical core drill must be thoroughly inspected to ensure that the instrument is intact, the blade is sharp, and there are no loose or damaged parts.

Disinfection and Cleaning: Medical core drills must be strictly disinfected and cleaned before and after use to prevent cross-infection.

Surgical Preparation: Before surgery, the surgical site must be accurately positioned and secured to ensure stability and safety of the surgical area.

Operational Details: When using a medical core drill, force and speed must be carefully controlled to avoid unnecessary damage to surrounding tissue.

Monitoring and Feedback: During the operation, the surgical area must be constantly monitored and the operating method adjusted promptly to ensure precision and safety.

Personal Protection: Operators using medical core drills must wear appropriate personal protective equipment, including gloves, masks, and goggles, to ensure safety during the procedure.

Cleaning and Maintenance: After the procedure, the medical cannulated drill must be thoroughly cleaned and disinfected and properly stored for future use.

Following Regulations: Operators must strictly follow the medical institution's operating procedures and comply with relevant laws, regulations, and standards.

Maintenance

Maintenance of medical core drills is crucial to ensuring their performance and safe use. The following are general maintenance instructions for medical core drills:

Cleaning and Disinfection: After use, medical core drills must be thoroughly cleaned and disinfected to prevent cross-infection. Use specialized cleaning and disinfecting agents and follow the medical institution's protocols for cleaning and disinfection.

Cutter Head Maintenance: Pay special attention to the drill head, ensuring it is smooth, sharp, and free of damaged or loose parts. Replace the drill head regularly, as necessary, in accordance with medical device regulations.

Storage: After cleaning and disinfection, store the drill in a dedicated instrument case or cabinet to prevent contamination and mechanical damage.

Regular Inspection: Perform a comprehensive inspection of the drill regularly, including its appearance, mechanical connections, and power cord, to ensure it is intact.

Avoid Force: During storage and transportation, avoid unnecessary compression or impact to prevent damage.

Follow procedures: Strictly adhere to the medical institution's equipment management regulations, perform maintenance according to the prescribed cycle, replace consumable parts promptly, and record all relevant operations.

Maintenance of medical cannulated drills must adhere to professional standards and procedures to ensure their safety and reliability during surgery. These maintenance measures will help extend the life of the medical cannulated drill and ensure its effectiveness during surgery.
