Abstract

The utility model discloses a bone hole detector, which comprises a dividing ruler and a handle, the handle is marked with a measuring cursor, the handle can slide along the dividing ruler, one end of the zero read number of dividing ruler is connected with a probe, the probe is a hollow pipe shape body, the lower end of pipe shape body is hinged with a rotary probe head, the lower end of probe can contain the probe head, and the controlling device for facilitating the probe head to unfold or fold is arranged on the dividing ruler, the probe head can unfold or fold automatically via controlling, so as to solve the problems that the probe head of prober is so small that the probe head can easily slip when the probe head hitches on the bone skinniness of the pair of opposite bone holes, and the probe head is too big to penetrate the bone hole, and the problem that the measuring precision is not exact can also be solved, so that the working efficiency can be improved, and the cost can be saved.

Description

Bone foramen sounder

Technical field

This utility model relates to a kind of Orthopeadic Surgery medical apparatus and instruments, relates in particular to a kind of measuring device that orthopaedics is measured the bone drill drilling depth that is used for.

Background technology

After execution fracture internal fixation operation is beaten the Wangue hole in clinical, measure the degree of depth in bone hole, select for use screw to fix according to the degree of depth again with bone foramen sounder.Therefore the degree of depth of measuring the bone hole is an of paramount importance step, all uses bone foramen sounder to measure the degree of depth in bone hole in clinical.

At present, the probe tips of applied bone foramen sounder is the probe at a right angle in clinical, and be subjected to the influence of bone drill drill bit, the size of bone drill boring all is certain, if easy slippage when desiring to tangle that probe is too small to side seam hole cortical bone, be not easy to pass when desiring to pass if probe is excessive to the side seam hole, bring great inconvenience to user, brought error also for simultaneously the degree of depth of measuring the bone hole, make the bone hole depth of measurement become big or diminish, the screw of selecting for use when making operation is long or too short, to select screw again for use, make troubles to operation, influenced work efficiency, increased cost.

Summary of the invention

Technical problem to be solved in the utility model provides the folding automatically of a kind of probe, increases its certainty of measurement, and bone foramen sounder simple to operate.

For achieving the above object, the technical solution of the utility model is: bone foramen sounder, comprise rule, sign has the handle of measuring vernier, described handle can slide along described rule, and zero reading one end of described rule is connected with probe, and described probe is the tubular body of hollow, the lower end of the probe of described tubular body is hinged with rotating probe, and the lower end of described probe can hold described probe; Described rule is provided with the probe manipulation device that can make probe open or pack up.

As a kind of improvement, described manipulation device comprise be arranged in the described rule and and the passage that is communicated with of described probe, the outer end of described rule is equipped with the spiral knob, be provided with flexible connecting rod in the described passage, the fixedly connected described spiral knob of one end of described flexible connecting rod, the other end and described probe are hinged.

Owing to adopt technique scheme, bone foramen sounder, comprise rule, sign has the handle of measuring vernier, described handle can slide along described rule, and zero reading one end of described rule is connected with probe, and described probe is the tubular body of hollow, the lower end of the probe of described tubular body is hinged with rotating probe, and the lower end of described probe can hold described probe; Described rule is provided with the probe manipulation device that can make probe open or pack up; The controlled folding automatically of probe, easy slippage and the excessive problem that is not easy to pass the bone hole of probe when the probe of bone foramen sounder is too small to be desired to tangle to side seam hole cortical bone have been solved, simultaneously also solve the not accurate enough problem of certainty of measurement, improved work efficiency, saved cost.

Description of drawings

Fig. 2 is the structural representation of this utility model embodiment probe when packing up.

The specific embodiment

Bone foramen sounder as shown in Figure 1, comprise rule 2, sign has the handle 1 of measuring vernier 11, described handle 1 can slide along described rule 2, zero reading one end of described rule is connected with probe 3, described probe 3 is the tubular body of hollow, and the lower end of the probe 3 of described tubular body is hinged with rotating probe 4, and the lower end of described probe 3 can hold described probe 4; Described rule 2 is provided with probe 4 manipulation devices that can make probe 4 open or pack up.

Described manipulation device comprise be arranged in the described rule 2 and and the passage that is communicated with of described probe 3, the outer end of described rule 2 is equipped with spiral knob 5, be provided with flexible connecting rod 6 in the described passage, the fixedly connected described spiral knob 5 of one end of described flexible connecting rod 6, the other end and described probe 4 are hinged.

The operation principle of present embodiment is as follows:

During use, toward external rotation, flexible connecting rod 6 pulling probes 4 are received in the probe body 3, and probe body 3 is inserted in the bone hole with spiral button 5, after the breakthrough sense is felt in the breakthrough second bone hole, the rotating screw button 5 inwards, and this moment, flexible connecting rod 6 promotion probes 4 were opened, and spurred the afterbody of rule 2 then, probe 4 hangs on the bone hole cortex of offside, handle 1 being pushed away forward, reading scale by measuring vernier 11, promptly is the degree of depth in bone hole; Push away rule 2 after having surveyed a little forward, the rotating screw button 5 outward, and probe body 3 is drawn in, withdraw from the bone hole and get final product.

According to clinical experience, probe 4 is accomplished suitable size, it can be caught on the cortex of side seam hole, avoided the too small error of the probe 4 excessive or too small measured values that bring.
