Orthopedic instruments generally refer to professional medical instruments specially used for orthopedic surgery. According to the classification of the US Food and Drug Administration, it is divided into Class I, Class II and Class III. According to the purpose and performance, it is mainly divided into orthopedic knives, orthopedic scissors, orthopedic pliers, orthopedic hooks, orthopedic needles, orthopedic scrapers, orthopedic cones, orthopedic drills, orthopedic saws, orthopedic chisels, orthopedic files, orthopedic useful mobile devices and so on. Here are four kinds of orthopedic instruments:
(1) Orthopedic knife
1. Osteotomy knife: It usually consists of a blade and a handle. The distal end has a rigid and sharp single-edged cutting blade, and the handle is located at its proximal end. It is usually made of stainless steel. Used for cutting and cutting bones.
2. Orthopedic endoscopic knife: usually composed of head, rod and handle. The head is a blade, and the work of the head is controlled by the transmission and control of the handle. The head is usually made of stainless steel. The operation was performed under the intraoperative endoscope, and it was used for minimally invasive surgery in plastic surgery to remove and peel off the diseased tissue. Such as intervertebral disc reamer, arthroscopic scalpel.
3. Reaming cutter: usually made of stainless steel, it consists of reamer and clamping handle or cutter head with reaming blade. It is used for reaming, reaming or reaming and reaming intervertebral discs in plastic surgery.
(2) Orthopedic cone
1. Tapered opening: It usually consists of a head and a handle with a cutting design. The head is usually made of stainless steel and is used to make holes in bones during plastic surgery.
2. Tap: It usually consists of a blade and a handle. The blade is usually made of stainless steel, and the handle is usually made of stainless steel or aluminum. Used for tapping threaded holes in bones during plastic surgery.
(3) Hook for orthopedics
1. The retractor of an orthopedic hook usually consists of a head and a handle, and the head has a hook head. Usually made of stainless steel. Used in orthopedic surgery to expose the surgical field of vision, make the operation easy, protect the tissue and avoid accidental injury; Or used in plastic surgery to peel, stretch or shield nerve roots. Commonly used are bone retractor, unilateral lamina retractor, lower limb amputation retractor, meniscus retractor, cervical retractor, lamina retractor, bending retractor, abdominal S retractor, hip retractor, knee retractor, scapula retractor, orthopedic nerve root retractor, (intervertebral) nerve root retractor, spinal surgical nerve retractor and spinal surgical nerve retractor.
2. The retractor is usually a hook-shaped structure of various forms (such as blunt type, sharp type, windowing type and deep type), which is a manually operated and self-locking surgical instrument. Usually made of stainless steel. It is used in orthopedic surgery to expose the surgical field of vision, make the operation easy, protect the tissue and avoid accidental injury. Common distractors include bone distractor, hand distractor, multidirectional distractor, bidirectional distractor, adjustable distractor, minimally invasive distractor, tibial distractor, joint minimally invasive distractor, posterior cranial distractor and so on.
3. Bone hooks usually consist of hooks and handles. The head of the hook is usually made of stainless steel. Used to support bones during orthopedic surgery.
(4) Scraping in orthopedics
1, orthopedic endoscopic curettage Arthroscopic curettage usually consists of head, rod or flexible catheter and handle. The head is spoon-shaped, and the work of the head is transmitted and controlled by the operation of the handle. The head is usually made of stainless steel. It is operated under endoscope during operation, and is used for scraping pathological tissues in minimally invasive orthopedic surgery.
2. A curette usually consists of a head and a handle. The proximal end has a handle, and the distal end has a spoon-shaped concave tip with a sharp edge, or it can be double-headed. Usually made of stainless steel. It is used to scrape the focus, sinus scar, granulation tissue, dead bone or bone cavity, and pathological tissue in potential cavity. Ordinary curettage, bone curettage, hollow bone curettage, straight cup-shaped bone curettage, lamina curettage, cervical curettage, vertebroplasty curettage, endplate curettage, vertebral curettage, scraper, etc.
Second, how to choose surgical instruments
The choice of surgical instruments can be seen from the strength of the brand. After all, medical surgical instruments are widely used and have high requirements. In order to ensure the smooth operation, there are naturally very high requirements for the selection of instruments.
First of all, we can know whether the equipment brand has good basic strength, good technical support, good processing and production, and so on. From the comprehensive brand strength of surgical instruments, choosing surgical instruments with high safety and good precision will also be of great help to the smooth operation.
At the same time, we should also be optimistic about the specifications, models and combinations of medical surgical instruments provided by different equipment brands to see if they have good application guarantee. Therefore, appropriate surgical instruments can be selected, and the application is safe and the operation is smoother.
