Abstract
A distal radius fracture reduction fixator belongs to medical instruments for bone fracture rehabilitation therapy and comprises a main fixing frame (1), a radius fixator (2), a radius fixing needle (3), a metacarpal bone fixator (4) and a metacarpal bone fixing needle (5). Needle holes and adjusting bolts (6) are arranged on the radius fixator (2) and the metacarpal bone fixator (4) respectively, and the radius fixing needle (3) and the metacarpal bone fixing needle (5) are inserted into the corresponding needle holes. The distal radius fracture reduction fixator is characterized in that the main fixing frame (1) is a cross bar with a bent included angle, the radius fixator (2) and the metacarpal bone fixator (4) are movably connected onto the main fixing frame (1). The distal radius fracture reduction fixator is simple in structure, simple and easy in operation, low in manufacturing cost and suitable for wide use, and the integral main fixing frame is used for replacing structures such as a complicated universal connector and the like, so that multiple adjustment is avoided effectively.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments of rehabilitation bone injury, particularly a kind of external holder that resets of correcting the distal radius unstable fracture.
Background technology
The chi radius far-end fracture is one of modal fracture of human body, and pilosity is born in person in middle and old age, and the women is more than the male.Mostly be due to the indirect violence, it is due to the direct violence that the minority case is also arranged.At present such treatment of fractures method mainly contain that manual reduction external plaster fixation, open reduction are fixed, support external fixation etc.Adopt which kind of Therapeutic Method to need to decide according to concrete traumatic condition.The manual reduction external plaster fixation be orthopaedics classics also be the most basic Therapeutic Method.But clinical practice finds that this method receives artificial factor bigger.Though open reduction internal fixation definite effect, patient need bear certain misery, and needs second operation to take out inner matter.Exterior fixation bracket is to use the widest a kind of Therapeutic Method now, and operation wound is little, and curative effect is sure.But existing chi distal radius fixed mount mostly has the universal wheel design, and some fixed mount also has flexible location regulatory function.Chinese patent " distal radius three-dimensional external fixer " (application number: 201020152490.4) just comprise device and structures such as main fixed mount, radius locking pin, flexible adapter, universal joint for example.This kind equipment can satisfy the requirement of clinical practice preferably, can regulate certain treatment attitude according to patient's concrete condition.But owing to contain multiple adjusting device such as universal joint, this type of fixed mount costs an arm and a leg, the tens thousand of easily units of every cover equipment price.China and in practical application; Because its adjusting and link are more; The medical worker need carry out the multistep operation and accomplish operation process, and each link of fixed mount can take place to slide relatively because connect not compact simultaneously, may cause the further damage to the patient.
Summary of the invention
The technical problem that this utility model will solve is: overcome the deficiency of prior art, radius far-end fracture reset holder a kind of simple in structure, easy to use, cheap is provided.
The technical scheme that this utility model technical solution problem is adopted is: comprise main fixed mount, radius holder and radius locking pin, metacarpal bone holder and metacarpal bone locking pin; Be respectively equipped with pin hole on radius holder and the metacarpal bone holder and regulate bolt; Radius locking pin, metacarpal bone locking pin insert in the corresponding pin hole; It is characterized in that: main fixed mount is one section cross bar with bending angle, and radius holder and metacarpal bone holder are movably connected on the main fixed mount.
The bending angle of said main fixed mount is 150～160 °.
Preferably, the bending angle of main fixed mount is 155 °.
Described radius holder and metacarpal bone holder are through tightening and unclamp the flexible connection of realization of adjusting bolt and main fixed mount.
The angle of arm radius and metacarpal bone is between 150～160 °, though this angle varies with each individual, clinical practice finds that fracture patient is rehabilitation, the angle that will fixedly maintain also in 150～160 ° scope.In other words, 150～160 ° angular range can satisfy the clinical practice requirement.Simultaneously, if select the main fixed mount of one for use, replace traditional holder that has devices such as universal joint, expansion link, the troublesome operation step when having avoided implementing fixing operation has more been avoided owing to each parts connects the not firm medical treatment fracture that causes.From considering economically; Select the main fixed mount of one for use; Abandon the holder of device such as universal joint; With respect to conventional fasteners, its cost cost will reduce greatly, this means that the medical institutions of numerous remote backward areas can use low-cost external immobilizer for fracture restitution to serve as the patient equally.
The method for using of actual method for using and traditional radius far-end fracture reset holder is similar.This utility model is positioned patient's fracture site, uses radius locking pin, metacarpal bone locking pin, be individually fixed on radius and the metacarpal bone, through pin hole, the radius holder links to each other with main fixed mount with the metacarpal bone holder.After the reduction of the fracture, tighten set bolt, main fixed mount is fixed in fracture site.
Compared with prior art; The beneficial effect that the radius far-end fracture reset holder of this utility model is had is: simple in structure; With the loaded down with trivial details structures such as universal joint of main fixed mount replace complex of one, effectively avoid repeatedly regulating, simple to operate easy-to-use; And cheap, suitable being widely used.

Fig. 2 is the structural representation of locking pin.
Wherein, 1, main fixed mount 2, radius holder 3, radius locking pin 4, metacarpal bone holder 5, metacarpal bone locking pin 6, regulate bolt.
Fig. 1 is the most preferred embodiment of this utility model, further specifies below in conjunction with 1 pair of this utility model of accompanying drawing:
The specific embodiment
This radius far-end fracture reset holder; Form by main fixed mount 1, radius holder 2 and radius locking pin 3, metacarpal bone holder 4 and metacarpal bone locking pin 5; Be respectively equipped with the pin hole and adjusting bolt 6 that have the slit on radius holder 2 and the metacarpal bone holder 4, radius locking pin 3, metacarpal bone locking pin 5 insert in the corresponding pin hole.Radius locking pin 3 is identical with metacarpal bone locking pin 5 structures, but radius locking pin 3 needle body diameters are greater than metacarpal bone locking pin 5 needle body diameters.Main fixed mount 1 is 155 ° a over brace for two sections angles of one, and radius holder 2 is movably connected on the main fixed mount 1 through regulating bolt 6 with metacarpal bone holder 4.
During use, this utility model is positioned patient's fracture site, uses radius locking pin 3, metacarpal bone locking pin 5 to puncture respectively on patient's radius and metacarpal bone, through pin hole, radius holder 2 is connected with main fixed mount 1 with metacarpal bone holder 4.After the reduction of the fracture, tighten and regulate bolt 6, main fixed mount 1 is fixed in fracture site.
The crooked angle of main fixed mount 1 can be 150 ° or 160 °, and other structures are identical with embodiment 1.
The above; It only is the preferred embodiment of this utility model; Be not to be the restriction of utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every this utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of this utility model technical scheme according to the technical spirit of this utility model.
