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
The present invention relates to the orthopedic medical device technical field, relate in particular to the soft brill of a kind of split type orthopaedics and manufacture method.
Background technology
In the orthopaedics therapy operation, the flexible axle of the general soft brill of using always of orthopaedics is by double-layer stainless steel skin, steel wire strand coiling or pass through welding, modes such as physical fixation are formed by connecting, when practical operation, because rigidity is excessive or too small, makes that the elasticity of soft brill is wayward, directed, and problem such as fracture takes place easily, the operation process operation is complicated, and unstable some complication that easily produce of product are brought misery to patient.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and use convenient and can guarantee to receive the soft brill of split type orthopaedics of better surgical effect, in order to reduce iatrogenic injury as far as possible, shorten operating time, alleviate the misery that patient will bear, make operation fast, finish safely.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: the soft brill of a kind of split type orthopaedics comprises: drillstock, and flexible axle, the cutting edge joint is connected, and also is provided with groove on the flexible axle, and it is characterized in that: described groove becomes the spiral spill.
Soft the drilling as method of a kind of split type orthopaedics of the present invention is, make the hollow flexible axle of a rigidity at first according to a conventional method, with the cylindrical of flexible axle each other benchmark process by numerical control finishing impression machine, with the track engraving of the groove in every group of chain link in the face of cylinder of flexible axle along its recessed shoulder, form upper and lower two groups of chain link spirals and connect, and the like get final product.
Advantage of the present invention is: the reasonable in design practicality, novelty is skillfully constructed, because special spiral spill design, elasticity is moderate, can adjust radian and easy fracture not arbitrarily, only need to mix corresponding electric drill at drillstock, the cutting edge joint is mixed the operation blade and can be used, and the whole operation process is simple, quick.

Fig. 2 is the soft brill groove structure of a kind of split type orthopaedics of the present invention sketch map.
Among Fig. 1: 1, drillstock, 2, flexible axle, 3, the cutting edge joint, 4, groove.
Among Fig. 2: 5, recessed shoulder.
The specific embodiment
Describe specific embodiments of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the soft brill of a kind of split type orthopaedics comprises: drillstock 1, and flexible axle 2, cutting edge joint 3 is connected, and also is provided with groove 4 on the flexible axle 2, it is characterized in that: 4 one-tenth spiral spills of described groove.Its manufacture method is, make the hollow flexible axle 2 of a rigidity at first according to a conventional method, with the cylindrical of flexible axle 2 each other benchmark process by numerical control finishing impression machine, with the track engraving of the groove 4 in every group of chain link in the face of cylinder of flexible axle 2 along its recessed shoulder 5, form upper and lower two groups of chain link spirals and connect, and the like get final product.A kind of split type orthopaedics of said structure is soft to be drilled in when using, and only needs to mix corresponding electric drill at drillstock 1, and cutting edge joint 3 is mixed the operation blade and can be used.
Claims (2)
1. soft brill of split type orthopaedics comprises: drillstock 1, and flexible axle 2, cutting edge joint 3 is connected, and also is provided with groove 4 on the flexible axle, it is characterized in that: 4 one-tenth spiral spills of described groove.
2. according to soft the drilling as method of the described a kind of split type orthopaedics of claim 1 be, make the hollow flexible axle 2 of a rigidity at first according to a conventional method, with the cylindrical of flexible axle 2 each other benchmark process by numerical control finishing impression machine, with the track engraving of the groove 4 in every group of chain link in the face of cylinder of flexible axle 2 along its recessed shoulder 5, form upper and lower two groups of chain link spirals and connect, and the like get final product.
