Universal matched water spraying device for orthopedic grinding drill
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a universal matched water spraying device for an orthopedic grinding drill.
Background
Osteology is also known as orthopedics. Is a specialty or discipline of medicine, which is specialized in studying the anatomy, physiology and pathology of the skeletal muscle system, maintaining and developing the normal morphology and function of the system using drugs, surgery and physical methods, and treating injuries and diseases of the system. In the process of orthopedic surgery, a large number of orthopedic grinding drills need to be used, and in order to prevent heat generated when bone is ground at high speed in the use process of the grinding drills from damaging bone cells, an assistant is usually required to inject water into a grinding area by using an injector to reduce the local temperature of a drill bit and a grinding bone surface. However, this procedure requires a good fit between the assistant and the operator, otherwise the location of the water injection is difficult to accurately concentrate to the surgical site, which affects the progress of the surgery, and the surgical nurse is required to fit the delivery syringe, which can easily cause the syringe to prick the assistant.
Craniotomy is also called craniotomy and is generally clinically an operation performed under the conditions of craniocerebral injury of a patient or removal of brain tumor of the patient. In general, a U-shaped opening is cut on the scalp of a patient's affected part, then several holes are made in the skull, and the skull is placed back to suture the wound after the corresponding skull is removed and medical procedures are performed.
The prior art also discloses technical schemes related to water spraying commonly used for orthopaedics grinding and drilling, for example, a chinese patent with application number CN201410717757.2, which discloses a water spraying device commonly used for orthopaedics grinding and drilling, comprising a grinding and drilling bit, a taper sleeve, a grinding and drilling handle, two water injection pipelines and a buckle, wherein the water injection pipeline is sleeved outside the bit, so that during grinding, water for cooling is directly injected to a grinding area through the grinding and drilling bit through the circular pipeline, not only can uniformly cool the bit, but also can accurately inject water to a ground bone surface, no additional injector is needed by an assistant for water injection, the purpose of saving manpower is achieved, and related complications are avoided, but injected water is not recovered, for operations requiring long-time grinding and drilling, such as craniotomy, more water is often needed to be injected, injected water flows everywhere without recovery, the operation table is easily polluted, thereby influencing the operation.
Therefore, the invention provides a water spraying device commonly used for an orthopedic grinding drill, which is characterized in that a ring II is attached to the surface of a skull of a patient, so that water sprayed to the surface of the skull of the patient for cooling cannot flow freely and drip, and the recovery of cooling water is realized, thereby ensuring the cleanness of an operation site, avoiding the flowing of the cooling water all around and further avoiding the pollution to operation equipment.
