Bone focus removing and flushing device

Abstract

The invention discloses a bone focus removing and flushing device which comprises a focus removing assembly, a collecting device and a power mechanism, the focus removing assembly comprises a drill bit, the drill bit is of a hollow structure, and a plurality of vertically-arranged blades are arranged on the outer end face of the drill bit at intervals; the bottom face of the drill bit is fixed to one end of a rotating shaft, the other end of the rotating shaft is connected with a power mechanism, a through hole communicated with the hollow structure of the drill bit is formed in the long axis direction of the rotating shaft, a spiral blade is arranged on the outer ring of the rotating shaft, the rotating shaft is sleeved with a collecting device, and a section of spiral blade is exposed out of the open end of the collecting device close to one end of the drill bit. The tail end of the collecting device is connected with the power mechanism, and a taking-out opening is formed in the side wall of the tail end. The power mechanism is provided with a water inlet and a water outlet, the water inlet is communicated with the through hole of the rotating shaft, and the water outlet is communicated with the tail end of the collecting device. The device is reasonable in structural design, easy to operate, free of device replacement, sufficient in positive-pressure flushing and thorough in debridement, and has the function of completing lesion removal at a time.

Description

technical field [0001] The invention relates to a flushing device, in particular to a bone lesion removal and flushing device. Background technique [0002] Bone lesions such as osteomyelitis, osteonecrosis, bone cysts, and benign bone tumors all involve surgical operations that require removal of the lesions. Once such lesions are formed, it is easy to cause local tissue ischemia and damage to the mechanical structure of trabecular bone, thereby causing local chronic pain and limb dysfunction, causing great pain to patients and affecting their quality of life. This disease is difficult to heal on its own, and when it develops to a certain stage, it is often necessary to completely remove the lesions through surgery to make room for the body’s own new bone regeneration. [0003] The published literature shows that a large amount of normal saline irrigation can effectively reduce the incidence of bone infection and effectively debride the osteomyelitis, but there is a lack o...

Problems solved by technology

[0004] For the above-mentioned diseases, curettes are often used to curette the lesion in clinical practice, and a C-arm machine is often used for intraoperative positioning, and the lesion is cured based on experience and hand feeling; curettage and washing are performed in turn, which is inefficient. Bone lesions in the deep part cannot be washed effectively, resulting in the retention of necrotic tissue, bacteria or tumor tissue, affecting the therapeutic effect
