Embodiment Construction

[0011] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0012] Such as figure 1 , figure 2 As shown, a split-type orthopedic soft drill includes: a drill handle 1, a flexible shaft 2, and a cutting edge joint 3 are integrated, and a groove 4 is also arranged on the flexible shaft 2, and it is characterized in that: the groove 4 spiral concave. The production method is as follows: firstly, a rigid hollow flexible shaft 2 is manufactured according to a conventional method, and the outer circle of the flexible shaft 2 is used as a reference to process it through a CNC engraving machine, and the concaves in each group of chain links on the cylindrical surface of the flexible shaft 2 are processed. Groove 4 is engraved along the track of its concave shoulder 5, forms upper and lower two groups of chain link helical connections, and so on gets final product. When a split-type orthopedic soft drill wi...

Abstract

The invention discloses an orthopaedic medical instrument, and in particular discloses a split type orthopaedic soft drill and a manufacturing method thereof. The split type orthopaedic soft drill comprises a drill handle, a soft shaft and a cutting edge joint which are connected to form a whole, wherein a groove is also formed in the soft shaft and is helically sunken. The manufacturing method comprises the following steps of: manufacturing the rigid hollow soft shaft by the conventional method, processing the soft drill by taking an outer circle of the soft shaft as a reference through a numerical control fine-engraving machine, engraving the groove in each group of chain section of a cylindrical surface of the soft shaft along a trace of a concave shoulder to form an upper group of chain section and a lower group of chain section which are helically connected, and performing the steps by parity of reasoning. Due to the special helical sunken design, the split type orthopaedic soft drill is proper in elasticity; the radian can be randomly adjusted; the split type orthopaedic soft drill is difficultly broken; and the whole operation process is simple and quick.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to a split-type orthopedic soft drill and a manufacturing method thereof. Background technique [0002] In orthopedic treatment operations, the flexible shaft of the commonly used orthopedic soft drill is made of double-layer stainless steel skin, multi-strand steel wire winding or connected by welding, physical fixation, etc. In actual operation, because the rigidity is too large or too small, The elasticity of the soft drill is not easy to control and orientation, and it is prone to problems such as fracture. The operation process is more complicated, and the instability of the product is easy to produce some complications to bring pain to the patient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a split-type orthopedic soft drill that is more convenient to use and can ensure better surgical resul...
