Abstract
The invention discloses a novel orthopaedic soft drill. The novel orthopaedic soft drill comprises a flexible drill stem, a rigid drill bit and a positioner, a drill handle, a hollow flexible shaft and a drill bit connector are connected integrally to form the flexible drill stem, and the hollow flexible shaft is provided with double helical grooves; the rigid drill bit is connected with the flexible drill stem through the drill bit connector, and the positioner is connected with the flexible drill stem through a connecting rod. The breaking strength of the flexible shaft of the novel orthopaedic soft drill provided by the invention is enhanced, accurate positioning is ensured by the arranged positioner during drilling, consequently, the drill bit is prevented from being broken, drilling deviation is prevented, and the soft tissue is protected; the novel orthopaedic soft drill increases working efficiency, alleviates the pain of patients, and improves the treatment effect.
Description
Technical field
The invention belongs to medical instruments field, particularly relate to the soft brill of a kind of novel orthopaedics.
Background technology
Soft brill is the common tool of pulp cavity reaming in current orthopedic medical device, and application number: CN201310238556.X discloses a kind of Split type orthopaedic soft drill and manufacture method.This Split type orthopaedic soft drill, comprise drillstock, flexible axle, cutting edge joint be connected, flexible axle is also provided with groove, and described groove becomes spiral spill.Manufacture method is, manufactures the flexible hollow shaft of a rigidity first according to a conventional method, is processed with the cylindrical acted as reference mutual of flexible axle by numerical control carving machine.Be provided with the steel band of some spills just as both sides, spiral winding becomes the flexible axle of recess and protuberance snapping, and its Resisting fractre intensity is more weak.Application number: 201320833092.2 disclose a kind of Double helix orthopaedic soft drill, and this Double helix orthopaedic soft drill, comprises flex-stem and rigid drill bit, and flex-stem is connected by drillstock, flexible hollow shaft and bit adapter, flexible hollow shaft is provided with Double helix wire casing.It can not realize precise positioning when holing, and easily causes borehole throw and damages other soft tissue.
Summary of the invention
The object of the present invention is to provide the soft brill of a kind of novel orthopaedics, be intended to solve current flexible axle Resisting fractre intensity more weak, can not precise positioning be realized during boring, easily cause borehole throw and damage the problem of other soft tissue.
Necessary technology scheme:
The present invention is achieved in that the soft brill of a kind of novel orthopaedics, and the soft brill of this novel orthopaedics comprises flex-stem, rigid drill bit, localizer, and flex-stem is connected by drillstock, flexible hollow shaft and bit adapter, flexible hollow shaft is provided with Double helix wire casing;
Rigid drill bit is connected with flex-stem by bit adapter, and localizer is connected with flex-stem by connecting rod.
Further, Double helix wire casing, is parallel to each other by two and the relative spill helix groove of spill forms.
Further, Double helix wire casing, forms some groups of chain link spirals and connects.
Further, the degree of depth of Double helix wire casing is for penetrating monolateral hole wall.
Further, the material of flex-stem and rigid drill bit is rustless steel or titanium.
Further, flex-stem is provided with the sliding tray be connected with localizer.
Effect gathers:
The soft brill of a kind of novel orthopaedics provided by the invention; improve the Resisting fractre intensity of flexible axle; by being provided with precise positioning during localizer guarantee boring; prevent the drill bit that fractures; avoid borehole throw, protect soft tissue, invention increases work efficiency; alleviate the misery of patient, improve therapeutic effect.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1 is the structure chart of the soft brill of a kind of novel orthopaedics that the embodiment of the present invention provides.For convenience of explanation, illustrate only part related to the present invention.
The present invention realizes like this, the soft brill of a kind of novel orthopaedics, the soft brill of this novel orthopaedics comprises flex-stem 1, rigid drill bit 2, localizer 7, and flex-stem 1 is connected by drillstock 3, flexible hollow shaft 4 and bit adapter 5, it is characterized in that flexible hollow shaft being provided with Double helix wire casing 6; Rigid drill bit 2 is connected with flex-stem 1 by bit adapter 5, and localizer 7 is connected with flex-stem 1 by connecting rod.Double helix wire casing 6, is parallel to each other by two and the relative spill helix groove of spill forms, and form some groups of chain link spirals and connect, the degree of depth of Double helix wire casing 6 is for penetrating monolateral hole wall; The material of flex-stem 1 and rigid drill bit 2 is rustless steel or titanium, and flex-stem 1 is provided with the sliding tray be connected with localizer 7.
The soft brill of a kind of novel orthopaedics provided by the invention, improve the Resisting fractre intensity of flexible axle, by being provided with precise positioning during localizer guarantee boring, when holing, first localizer is fixed on the position of required boring, then fixed locator, rigid drill bit is holed in locator holes, when drill bit gos deep into, localizer is connected with flex-stem by sliding tray, ensure that the accuracy of boring all the time.Prevent the drill bit that fractures simultaneously, avoid borehole throw, protect soft tissue, invention increases work efficiency, alleviate the misery of patient, improve therapeutic effect.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
