Description

A kind of spiral Medical orthopedic gypsum demolition reduction device

Technical field

The utility model relates to medical instruments fields, in particular, being related to that a kind of spiral Medical orthopedic gypsum is broken to be torn open Except device.

Background technique

Currently, the application of gypsum is than wide, for fixed fracture injury, effect in hospital's especially orthopedics and traumatology It is obvious, and can also guarantee that it will not be tampered using the fixed injured limbs of gypsum and cause secondary injury, but in gypsum Dismounting in terms of, typically use sawing, the then mode of manual demolition, in this way first is that in cutting and dismounting, grasp is not Dynamics is removed well, be easy to cause the secondary insult of patient, second is that manual demolition is relatively elaborate, efficiency is relatively low, this is existing skill The shortcoming of art.

Utility model content

The technical problem to be solved by the present invention is to provide a kind of spiral Medical orthopedic gypsum demolition reduction device, sides Just fracture patient is squeezed at gypsum and is removed.

The utility model adopts the following technical solution realizes goal of the invention:

A kind of spiral Medical orthopedic gypsum demolition reduction device, including bracket, it is characterized in that: fixed above the bracket There is hydraulic cylinder, piston rod is installed in the hydraulic cylinder, the piston-rod lower end is fixed on push plate upper end, the push plate two sides point It is not provided with two groups of shafts, push plate two sides shaft and connecting rod one end are hinged, and the connecting rod other end is hinged in moving arm In portion's shaft, moving arm upper end slide-bar is interspersed in two side chute of bracket, and the moving arm lower thread is connected with Three groups of screw rods, each described screw rod one end are connected with threading drill bit, and the intermediate screw rod other end is fixed with driving gear, described Driving gear end face is fixed with handle, and the driving gear eccentric part is threaded with stop screw, and screw rod described in two sides is another End is respectively fixed with driven gear.

As further limiting for the technical program, the moving arm upper end slide-bar end is provided with hubcap.

Compared with prior art, the advantages and positive effects of the utility model are as follows: will need to remove gypsum position is put into two In the threading drill bit of side, the screw-in depth of stop screw is adjusted to pierce depth in gypsum needed for controlling, after adjusting stop screw, Rotational handle drives driving gear, and driving gear is engaged with two sides driven gear, drives three groups of screw rod rotations, the tapping on screw rod Drill bit screws in gypsum, and when stop screw withstands on moving arm end face, stop operating handle, and the piston rod in hydraulic cylinder is to moving down It is dynamic, it drives push plate to move down, makes connecting rod that moving arm be pushed to expand in reverse direction, achieve the purpose that destroy gypsum.This is practical new Type is provided with stop screw, pierces depth for threading drill bit and provides accurate control, makes to avoid causing patient in demolishing process Secondary injury, while also improving the working efficiency of dismounting.

Specific embodiment

With reference to the accompanying drawing, a specific embodiment of the utility model is described in detail, it is to be understood that this The protection scope of utility model is not limited by the specific implementation.

As Figure 1-Figure 5, the utility model includes bracket 2, and the bracket 2 is fixedly arranged above hydraulic cylinder 1, described hydraulic Piston rod 12 is installed, 12 lower end of piston rod is fixed on 10 upper end of push plate, and 10 two sides of push plate are respectively arranged in cylinder 1 Two groups of shafts, the 10 two sides shaft of push plate and 3 one end of connecting rod are hinged, and 3 other end of connecting rod, which is hinged in the middle part of moving arm 4, to be turned On axis, the 4 upper end slide-bar of moving arm is interspersed in 2 liang of side chutes of the bracket, and 4 lower thread of moving arm is connected with three Group screw rod 8, described 8 one end of screw rod are connected with threading drill bit 9, and intermediate 8 other end of screw rod is fixed with driving gear 7, described 7 end face of driving gear is fixed with handle 6, and 7 eccentric part of driving gear is threaded with stop screw 11, the two sides screw rod 8 other ends are fixed with driven gear 5.

The 4 upper end slide-bar end of moving arm is provided with hubcap 13.

Utility model works process are as follows: when gypsum demolition reduction, the position for being equipped with gypsum is put into two sides threading drill bit 9 Interior, rotational handle 6 makes its tip just touch gypsum, at this time rotary stopper screw 11,11 end face of stop screw and moving arm The distance between outer end face will as pierce the depth in gypsum, and rotating handle 6 drives driving gear 7 to rotate at this time, driving tooth Wheel 7 drives screw rod 8 and threading drill bit 9 to rotate, and driving gear 7 is also engaged with two sides driven gear 5, when driving gear 7 is clockwise When rotation, the then rotation counterclockwise of two sides driven gear 5, so intermediate threading drill bit 9 is phase with 9 thread rotary orientation of two sides threading drill bit Opposite direction, i.e. a side are that then another party is left hand thread to right-handed thread, and threading drill bit 9 is special drill, and head has tapping spiral shell Line also shoots screw thread while piercing in gypsum in it, and 1 sidewall upper of hydraulic cylinder is provided with oil inlet, and side wall lower ends are set It is equipped with oil return opening, oil inlet and oil return mouth and external hand pump connect, and 1 oil inlet of oil cylinder makes piston rod 12 that push plate 10 be driven to move down, and pushes away Plate 10, which is moved down, pushes moving arm 4 by connecting rod 3, expands the opposite direction translation along 2 lower end sliding slot of bracket of 4 upper end slide-bar of moving arm , since there is screw thread self-locking function to reach demolition reduction so threading drill bit 9 destroys gypsum structure under the effect of external force Purpose completes entire demolition reduction process.

Disclosed above is only a specific embodiment of the utility model, and still, the utility model is not limited to this, The changes that any person skilled in the art can think of should all fall into the protection scope of the utility model.
