Abstract
本实用新型公开一种神经根保护骨凿，它包括神经根拉钩和骨凿，所述的神经根拉钩包括由前段钩体和后段钩体一体连接形成的L型钩体，所述前段钩体的末端设有向下折弯的钩头，所述前段钩体的表面上设有滑槽，所述的骨凿安装在所述的滑槽内。本实用新型设计的神经根保护骨凿，在进行骨髓纵裂手术过程中，采用神经根拉钩将血管神经拉开的同时，采用骨凿沿滑槽方向凿开骨皮质，便于操作，手术过程安全可靠，不会造成神经损伤，减少手术过程中的操作人数，提高手术效率。另外设在所述钩头内板面上的防滑凸点可提高拉钩的防滑性能，更有利于手术操作。
The utility model discloses a nerve root protection osteotome, which comprises a nerve root retractor and an osteotome. The nerve root retractor comprises an L-shaped hook formed by integrally connecting a front hook body and a rear hook body. The front hook The end of the body is provided with a downwardly bent hook head, and the surface of the front section of the hook body is provided with a chute, and the osteotome is installed in the chute. The nerve root protection osteotome designed by the utility model uses the nerve root retractor to open the blood vessels and nerves while the bone chisel is used to cut the bone cortex along the direction of the chute during the operation of longitudinal fracture of the bone marrow, which is easy to operate and safe in the operation process. Reliable, will not cause nerve damage, reduce the number of operators during the operation, and improve operation efficiency. In addition, the anti-slip protrusions provided on the inner surface of the hook head can improve the anti-slip performance of the draw hook, which is more conducive to operation.
Description
技术领域technical field
本实用新型属于医疗器械领域，具体涉及一种神经根保护骨凿。The utility model belongs to the field of medical instruments, in particular to a nerve root protection osteotome.
背景技术Background technique
采用骨凿进行骨髓纵裂手术时，极易损伤神经，需要助手牵拉神经拉钩进行配合操作，否则骨凿容易损伤神经或脊髓。但是在手术时的同时操作神经根拉钩和骨凿，需要的人手多，但是手术过程中由于受到手术空间的局限，在狭小的手术空间中，频繁更换手术器械，会延长手术时间，降低手术效率，增加患者产生手术并发症的风险。因此需要设计一种神经根保护骨凿。When the osteotome is used for diastematomyelia surgery, it is very easy to damage the nerve, and an assistant is required to pull the nerve retractor to cooperate with the operation, otherwise the osteotome is easy to damage the nerve or spinal cord. However, operating the nerve root retractor and osteotome at the same time during the operation requires a lot of manpower. However, due to the limitation of the operation space during the operation, frequent replacement of surgical instruments in the narrow operation space will prolong the operation time and reduce the operation efficiency. , increasing the patient's risk of surgical complications. Therefore need to design a kind of nerve root protection osteotome.
