Description
Technical Field
The utility model discloses an ultrasonic osteotomy cutter with double-way water inlet regulation and control, and relates to an electric cutter for orthopedic surgery.
Background
Intraspinal tumor (SCT) refers to a generic term for primary or metastatic tumors that occur in the spinal cord itself and tissues adjacent to the spinal cord within the spinal canal. The first treatment method is surgical resection to achieve tumor resection, relieve spinal cord compression and maintain spinal biomechanical stability. The main surgical modalities include laminectomy (1 amidomyc, LAMT), spinal reconstruction (1aminoplasty, LAMP). The operation time is long and bleeding is much when the lumbar vertebral plate is cut off in the operation. However, as the medical level is continuously developed, an Ultrasonic osteotomy tool (Ultrasonic bone cute UBC) is now frequently used for the operation. The osteotomy tool ultrasonic osteotome is a novel bone cutting system, is used as a novel bone cutting tool, and has the advantages of high bone cutting efficiency, no soft tissue cutting, and reduction of dural sac and nerve root injury compared with the traditional osteotomy tool; therefore, the electric energy is widely applied clinically, and the working principle of the electric energy-saving heat pump converts the electric energy into mechanical energy to generate higher heat; therefore, the cutter head and the handle must be cooled in the use process, so that on one hand, the contact surface of the cutter head and the target tissue is prevented from generating high temperature due to friction, and the cutter head and the target tissue are prevented from being possibly scalded; on the other hand, the handle is damaged due to overheating so as to prevent thermal damage.
However, the problem of high heat generation is still existed in the using process, which brings about heat accumulation and further influences. In-vitro experimental studies have been reported abroad that the temperature of the ultrasonic osteotome is 55.5-65.5 ℃ during operation, but the critical temperature of the nerve thermal injury is 43 ℃ and exceeds the critical point, which can cause the nerve thermal injury. There are related reports on the complications of the thermal effect of the ultrasonic osteotome, and when a foreign scholars Parker operates 40 patients, 1 patient (2.5%) has thermal injury to the dura mater due to overhigh local temperature. When the ultrasonic osteotome is used for spine surgery, accidents of dura mater tearing related to thermal effect happen occasionally; further, it is reported in the literature that complications of incision edge thermal burn and nerve root injury caused by an ultrasonic osteotome are found in operative cases of cervical spinal stenosis and thoracic spinal stenosis. Also, Eriksson and Albrektsso believe that temperatures in excess of 47 ℃ for 1 minute lead to irreversible necrosis of bone cells; temperatures in excess of 50 c for 1 minute can result in irreversible changes in the structure and physical properties of the bone. Therefore, the heat dissipation scheme of the current ultrasonic osteotome cannot solve the problem that the temperature rise may cause heat damage to nerves and surrounding tissues and change the bone structure during operation. Therefore, a new ultrasonic osteotome is needed to meet the actual surgical requirements.
