Abstract
The utility model discloses an inflating sleeve bolt for orthopedics. The inflating sleeve bolt for the orthopedics comprises a threaded sleeve and a screw. The threaded sleeve is connected with the screw through a thread, and the thread is embedded on the threaded sleeve. Both the threaded sleeve and the top portion of the screw are of double-hexagon structure, and the length of the screw and the threaded sleeve is equal. Due to the fact that the threaded sleeve is connected with the screw in threaded mode, an appropriate pressure can be imposed on transverse displaced fracture. Besides, screws can be chosen without considering the length of the screw according to displacement of fracture, thus the inflating sleeve bolt for the orthopedics is helpful for effective replacement of the transverse displaced fracture.
Description
Technical field
This utility model belongs to technical field of medical instruments, especially a kind of orthopaedics compressive sleeve bolt.
Background technology
Fracture refers to a kind of disease of causing sclerotin partially or completely to rupture owing to reasons such as wound or pathology.The obvious fracture of some transverse shift need to be exerted pressure to it by internal fixation apparatus and be helped the reduction of the fracture, but the general conventional pressurized bolt that adopts helps to reset fixing in now clinical, be that screw is thrown into from an end of lateral separation fracture, offside passes rear screw-in hexagon bolt, by the reduction of the fracture that screws in the pressure help lateral separation that produces, this sampling device need consider width and the fracture separation degree of fracture site and select the different length screw, need rule of thumb select screw length after the boring depth measurement, often repeatedly change screw because of correct estimated length, also long screw tail end need be wiped out after the pressurization, but because the screw of cutting off nail tail is sharp keen, easily stimulate soft tissue to produce pain.
The utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of screw length that can need not accurately to estimate, and need not to wipe out the spike tail after the pressurization, guaranteeing effectively exerts pressure to the transverse shift fracture satisfies the orthopaedics compressive sleeve bolt that resets.
This utility model adopts following technical scheme to realize its purpose: a kind of orthopaedics compressive sleeve bolt, comprise screw shell and screw, it is characterized in that: screw shell and screw interconnect by screw thread, the embedded screw thread of screw shell, screw shell and screw top are two hexagonal structures, and screw and screw socket are isometric.
The beneficial effect that the technical scheme that adopts this utility model to provide can reach is: this utility model adopts screw shell and screw to be threaded connection, can apply comparatively suitable pressure to the transverse shift fracture, need not accurately to estimate screw length, and need not to wipe out the spike tail after the pressurization, guaranteeing effectively exerts pressure to the transverse shift fracture satisfies the clinically use of orthopaedics.
Description of drawings
Fig. 1 is this utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail:
As shown in Figure 1, be this utility model structural representation, a kind of orthopaedics compressive sleeve bolt, comprise screw shell 2 and screw 1, screw shell 2 and screw 1 interconnect by screw thread, screw shell 2 embedded screw threads, and screw shell 2 and screw 1 top are two hexagonal structures.This utility model adopts screw shell and screw to be threaded connection, for a kind of screw length that can need not accurately to estimate is provided clinically, and need not pressurization and wiped out the spike tail after resetting, and guarantee effectively to the transverse shift fracture exert pressure, the satisfied orthopaedics compressive sleeve bolt that resets.
Claims (2)
1. an orthopaedics compressive sleeve bolt comprises screw shell and screw, and it is characterized in that: screw shell and screw interconnect by screw thread, the embedded screw thread of screw shell.
2. described orthopaedics compressive sleeve bolt according to claim 1, it is characterized in that: screw shell and screw top are two hexagonal structures, and screw and screw socket are isometric.
