Abstract
The utility model relates to a fracture restoring device which is a medical appliance suitable for being used in the restoring operations of the fracture of long tubular bones of four limbs. The utility model is composed of a slide way whose end is provided with a small hook in the shape of the mouth of an eagle, a propelling rod opposite to the slide way, an inner tube driving the propelling rod and an outer tube fixing the slide way. The utility model is used for enabling the restoring operation of fracture to be convenient, flexible, accurate, time-saving and labor-saving, reducing the tissue injury of organisms and improving the quality of operations.
Description
The fracture reposition instrument that this utility model relates to is a kind of medical apparatus and instruments that is used for the reduction of the fracture when carrying out the long bone fracture operation.
Before this apparatus of research, treatment to long bone fracture, the general muscular tissue that adopts is extensively separated, in case of necessity that muscle is cross-section, manifest fracture end, need then two above doctors with maneuver with the reduction of the fracture, because limb muscle prosperity, fracture end overlaps dislocation obviously, and its operation effort of manual reduction is time-consuming, soft tissue injury is big.
The purpose of this utility model is: a kind of fracture reposition instrument is provided, and this apparatus adopts lever, and lame shape slideway, pushing and withstanding structure can make the reduction of the fracture accurate, flexible, easy to operate, time saving and energy saving, better reduction, and surrounding soft tissue's damage is few.
The technical solution of the utility model is: a kind of fracture reposition instrument, have outer tube, and outer tube one end is equipped with end cap, the other end and slideway are connected, the slideway end is the little hook of olecranon-like, and interior pipe is housed in the outer tube, in the interior pipe pushing ram is housed, there is screw thread on the pushing ram surface, the plane is axially arranged, and interior Guan Yiduan and handle are connected, the other end and pushing ram threaded engagement, it is relative with chute on the slideway that pushing ram passes the inside and outside mouth of pipe, and the spacer pin that is installed on the outer tube wall is vertical with the plane of pushing ram.
During use, turning handle makes the interior pipe that is connected with it moving in the outer tube transfer, and the pushing ram that cooperates with Internal Pipe Thread under the restriction of the inside and outside mouth of pipe, can not arbitrarily rotate, and do straight-line displacement, stretches out the inside and outside mouth of pipe, and is fixed by spacer pin.When the reduction of the fracture is treated, fracture end cuts an osculum, an end hook that the little hook of olecranon is stretched to fracture is lived cortical bone, again the fracture other end is put into the chute of slideway, handle is upwards lifted, and utilizes the effect of lever, and the fracture two ends are moved on on the horizontal plane, it is close to the other end that turning handle makes the pushing ram pushing and withstanding end of fracturing then, until accurately resetting.
This apparatus confirms to have reached easy to operate, accurately time saving and energy saving flexibly to reduction of the fracture treatment through clinical practice, to the little purpose of design of body tissue damage.It has alleviated doctor's labor intensity, has improved the operation quality, has shortened operating time.
Below in conjunction with drawings and Examples this utility model is further specified:
Fig. 1 is the structural representation of this utility model fracture reposition instrument.
Fig. 2 is the A-A profile of this utility model Fig. 1.
Fig. 3 is the B-B profile of this utility model Fig. 1.
Fig. 4 is the C-C profile of this utility model Fig. 1.
Among the figure, outer tube (3) one ends and end cap (5) threaded engagement, the other end and slideway (2) are connected, and slideway is that elongate in shape end from coarse to fine is the little hook-type of olecranon, and the cross section of slideway is to be surrounded by two camber lines.Be equipped with in the outer tube and its interior pipe (4) movingly, pushing ram (1) is housed again in the interior pipe, interior Guan Yiduan, the hole and the handle (6) that pass end cap (5) are connected, and the other end of interior pipe is provided with female thread, and the female thread of interior pipe matches with the external screw thread of pushing ram.An axial plane (8) is arranged on the cylinder of pushing ram, this plane cooperates with the inside and outside mouth of pipe, the spacer pin (7) that is contained on the outer tube wall contacts with plane (8), realize the location, pipe rotated in turning handle (6) made, and was subjected to the restriction of the mouth of pipe with its plane of pushing ram (1) of interior pipe (4) threaded engagement, can not arbitrarily rotate, then under the promotion of screw thread, do straight-line displacement, and stretch out the inside and outside mouth of pipe.Pushing ram (1) at the inner and outer pipes external activity is corresponding with the chute of slideway (2).
Claims (1)
1, a kind of fracture reposition instrument has outer tube, and outer tube one end is equipped with end cap, the other end and slideway are connected, the slideway end is the little hook of olecranon-like, and interior pipe is housed in the outer tube, in the interior pipe pushing ram is housed, there is screw thread on the pushing ram surface, the plane is axially arranged, and interior Guan Yiduan and handle are connected, the other end and pushing ram threaded engagement, it is relative with chute on the slideway that pushing ram passes the inside and outside mouth of pipe, and the spacer pin that is installed on the outer tube wall is vertical with the plane of pushing ram.
