Description
Technical field
The invention belongs to Medical orthopedic equipment technology fields, are related to a kind of taking-up of memorial alloy encircling type clavicle bone fracture device
Tool.
Background technology
In bone surgery, memorial alloy encircling type clavicle bone fracture device is often used to handle fracture of clavicle, but due to memory
Alloy encircling type clavicle bone fracture device structure is special, and doctor is difficult big when taking out clavicle bone fracture device.Therefore memorial alloy encircling type
The taking-up tool of clavicle bone fracture device plays an important role.Currently, common memorial alloy encircling type clavicle bone fracture device takes out
Tool has Special withdrawing forceps, distraction forcep etc., but these taking-up tools are not only inconvenient to use in the course of surgery, and efficiency
It is low；In addition, if taking out memorial alloy encircling type clavicle bone fracture device with tools such as Special withdrawing forceps or distraction forceps；It will first strut
Bone fracture device one end encircles arm, then goes the arm of encircling for strutting the other end that could take out it completely, is possible to strut lock in this way
That distracted one end encircles arm and will restore before when the bone bone fracture device other end encircles arm.Taking-up is not easy, and is brought to operation
Prodigious difficulty；Prodigious pain is brought to patient；Also many inconvenience is brought to doctor.
Invention content
The shortcomings that the technical problem to be solved by the present invention is to be directed in the prior art and provide and a kind of greatly saving hand
The art time makes surgical procedure simplicity, easily memorial alloy encircling type clavicle bone fracture device taking-up tool, present invention taking-up clavicle connect
Both ends strut simultaneously when bone object, can once take out.
Technical problem to solve the present invention adopts the following technical scheme that：
A kind of memorial alloy encircling type clavicle bone fracture device taking-up tool, including holder, the holder include being connected by thread spindle
The left socle and right support connect, the thread spindle lower end are equipped with boss, and the left socle and right support are sleeved on the outside of thread spindle,
The left socle and right support both sides are symmetrical arranged by axis pin takes out hook, torsional spring is arranged between taking-up hook and the holder, institute
The screw thread that thread spindle upper outside is equipped with dextrorotation is stated, the thread spindle is hollow and is internally provided with left-handed rectangular thread, the spiral shell
Line axis upper outside is connect with casing threads, and swing arm, the swing arm lower end and thread spindle inner rectangular spiral shell are set in described sleeve pipe
Line is threadedly coupled, swing arm lower end connection left pressing plate and right pressing plate, the left pressing plate and right pressing plate be located at left socle and
Below right support, the left pressing plate and right pressing plate flexible connection.
Swing arm handle is arranged in the swing arm upper end.
Casing handle is arranged in described sleeve pipe upper end.
Memorial alloy encircling type clavicle bone fracture device of the present invention takes out tool and belongs to a kind of Medical orthopedic utensil of stainless steel.This
The memorial alloy encircling type clavicle bone fracture device advantage of invention is simple in structure, and the straight type clavicle bone fracture device of memorial alloy encircling type is in people
Micro-deformation may occur after implantation a period of time for body, and left and right holder and left and right pressing plate can rotate certain angle along swing arm axis
Degree solves the problems, such as to be not easily taken out after micro-deformation occurs for bone fracture device to be suitable for curved and straight type clavicle, convenient and practical.
Kit can solve the problems, such as the taking-up of memorial alloy encircling type clavicle bone fracture device, steady during taking out, light, side
Just, safe and reliable when taking-up bone fracture device, the time is saved in operation, reduces the pain of patient.It can once take out and entirely encircle
Formula clavicle bone fracture device, makes operating time greatly shorten, and it is difficult to reduce operation.It is postoperative to split cleaning, again convenient for cleaning-sterilizing
With.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is side view of the present invention；
Fig. 3 is partial structural diagram.
Specific implementation mode
Present invention will be described in further detail below with reference to the accompanying drawings：
A kind of memorial alloy encircling type clavicle bone fracture device taking-up tool, including holder, the holder include right by thread spindle 4
The left socle 2 and right support 10 of connection, left socle 2 and right support 10 is claimed to be adapted to, 2 both sides of left socle are symmetrically installed by axis pin 12
Hook 3 is taken out, takes out and torsional spring 13 is installed between hook 3 and left socle 2.10 both sides of right support are symmetrically installed by axis pin 12 and take out hook 3,
It takes out and torsional spring 13 is installed between hook 3 and right support 10.Boss is arranged in 4 lower end outside of thread spindle, and left socle 2 and right support 10 are set with
In 4 outside of thread spindle.4 upper outside of thread spindle is equipped with the screw thread of dextrorotation, and thread spindle 4 is hollow and is internally provided with left-handed rectangle spiral shell
Line, 4 upper outside of thread spindle are threadedly coupled with casing 5, to fix left socle 2 and right support 10 play in an axial direction, on casing 5
End setting casing handle 7.Swing arm 6 is set in casing 5, swing arm handle 8 is arranged in 6 upper end of swing arm.Swing arm 6 and 4 inside of thread spindle
