Abstract
A nail hole depth measurer comprises a sliding sleeve, a scale and a probe, and is characterized in that the sliding sleeve is sleeved outside the scale and the probe; a sleeve cover with a semicircle hole is arranged at the upper end of the sliding sleeve; an elastic cylinder is used as the probe; the middle of the probe is downwards divided into a fork shape with two stretched edges; and hangers are respectively arranged at the ends of the fork shape. When the nail hole depth measurer is used, the probe with the middle divided into the fork shape can be drawn together by downwards moving the sliding sleeve and then is inserted into a bone hole, the sliding sleeve upwards moves, and as the middle of the probe has the fork shape with the two stretched edges, the hangers arranged at the fork-shaped ends can automatically hook two edges of the bone hole; and after the measurement is finished, the sliding sleeve downwards moves so as to draw the fork-shaped hangers stretching towards two sides, and the measurer can be taken out. The nail hole depth measurer has the benefits of being simple in operation and convenient to use.
Description
Technical field
This utility model relates to a kind of auxiliary medical apparatus, specifically a kind of nail hole depth measuring device.
Background technology
At present, be known in the process of clinical synthetism, need two fracture ends are punched; With depth finder beating bone hole is measured then; Select corresponding steel nail and steel plate that fracture is fixed well, existing depth finder is complex structure not only, and probe front has only a little hook; The phenomenon that slippage when measuring, often occurs has brought inconvenience for medical worker's work.
Summary of the invention
This utility model technical problem to be solved is the deficiency that overcomes above-mentioned prior art, and a kind of simple structure is provided, nail hole depth measuring device easy to use.
This utility model solves the technical scheme that its above-mentioned technical problem adopted: a kind of nail hole depth measuring device; It comprises sliding sleeve, scale and probe; It is characterized in that: said sliding sleeve is enclosed within outside scale and the probe, and said sliding sleeve upper end is provided with the upper shield that has semicircle orifice, and said probe is elastic cylinder; The middle part of said probe is divided into the fork-shaped of upholding to both sides downwards, and bifid termination is respectively equipped with hook.Can said probe middle part be divided into bifid probe downwards during use and move down elder generation's gathering together, insert the bone hole then, moving on the sliding sleeve through sliding sleeve; Because of the middle part of said probe is downwards the fork-shaped of upholding to both sides; So the hook that is located at the fork-shaped termination then can automatic hook on both sides, bone hole, measure accomplish after, sliding sleeve is moved down; The fork-shaped hook that gathering is upheld to both sides, taking-up gets final product.
The beneficial effect of this utility model is: simple to operate, easy to use.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Accompanying drawing is the overall structure sketch map of this utility model.
Among the figure: 1. sliding sleeve, 2. upper shield, 3. scale, 4. probe, 5. fork-shaped, 6. hook.
The specific embodiment
In the drawings; A kind of nail hole depth measuring device, it comprises sliding sleeve 1, scale 3 and probe 4, it is characterized in that: said sliding sleeve 1 is enclosed within outside scale 3 and the probe 4; Said sliding sleeve upper end is provided with the upper shield 2 that has semicircle orifice; Said probe 4 is elastic cylinders, and the middle part of said probe 4 is divided into the fork-shaped 5 of upholding to both sides downwards, and the termination of fork-shaped 5 is respectively equipped with hook 6.Can the probe that said probe 4 middle parts are divided into fork-shaped 5 downwards be moved down earlier through sliding sleeve 1 during use and draw in together, insert the bone hole then, moving on the sliding sleeve 1; Because of the middle part of said probe 4 is downwards the fork-shaped of upholding to both sides; So be located at 6 of the hooks of fork-shaped 5 terminations can automatic hook on both sides, bone hole, measure accomplish after, sliding sleeve 1 is moved down; Fork-shaped 5 hooks 6 that gathering is upheld to both sides, taking-up gets final product.
