Novel bone foramen sounder

Technical field:

This utility model relates to the Orthopeadic Surgery technical field of medical instruments, is used to measure the novel bone foramen sounder of bone drill drilling depth.

Background technology:

During clinical execution fracture operation, its therapeutic modality need be holed at fracture end mostly, and materials such as reuse screw are fixed.After fracture end boring, need carry out depth measurement to the bone hole of boring, and, select the screw of suitable length to fix according to the bone hole depth of measuring, the depth finder that is used for the depth measurement of bone hole at present is that a rule is enclosed within the sleeve mostly, again with rule one end by extending to form measuring staff, with an one-sided location of measuring staff end bending gib head, but gib head is a little right angle, in use, gib head slides easily, not easy to operate, and depth measurement is inaccurate, influences the operation progress.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of tool capable anti-skidding, and can fast, accurately measure the novel bone foramen sounder of bone hole depth.

For achieving the above object, technical scheme provided by the utility model is: novel bone foramen sounder, it includes handle, rule, it also includes probe body, wherein, the rule activity is assemblied in the handle, and handle one end is provided with fixedly screens, and the other end is equipped with knob, probe body is connected to rule one end after passing movable span on the knob, the rule other end extends to outside the handle, and probe body includes sleeve and probe, wherein, sleeve is assemblied in the movable span of knob, in the probe set trap tube, the probe tip end is provided with the shell fragment hook of jag, and the probe afterbody is connected on the rule after passing sleeve.

Described probe afterbody is provided with screw thread, and is connected with the connecting hole of rule by screw thread.

The contacted end of described sleeve and knob is provided with anti-dislocation.

The end that described rule is positioned at handle is provided with the slip screens.

Described probe body can be bending.

Described probe body can be spring body.

Shell fragment hook front end behind the described jag is parallel to each other.

Described knob is screw thread, fit with the connected mode of handle, engage mode.

This utility model is after having adopted such scheme, and during use, left hand is held rule, the right hand pinches the sleeve of probe body, and the right hand pushes away forward, and left hand pulls back, gathering shell fragment hook inserts probe body in the bone hole, and left hand pushes away rule, the right hand pinches sleeve and pulls back, and probe ejects from barrel forward end and is parallel symmetric shell fragment hook, and left hand draws the afterbody of rule then, the shell fragment hook just hangs on the cortex of side seam hole, handle being pushed away forward again, read scale, promptly is the bone hole depth.Left hand is held rule and is pulled back, and the right hand pushes away sleeve forward, and the shell fragment hook is drawn in, then depth finder is withdrawed from the bone hole.Adopt the shell fragment hook of this programme to be difficult for slippage, easy to operate, and easy to use, can measure the bone hole depth fast and accurately.

The specific embodiment:

The utility model is described in further detail to accompanying drawing 5 below in conjunction with accompanying drawing 1, and preferred embodiment of the present utility model is:

Embodiment 1, referring to accompanying drawing 1 to accompanying drawing 4, the described novel bone foramen sounder of present embodiment, it includes handle 1, rule 2, probe body 3, wherein, rule 2 activities are assemblied in the handle 1, the end that rule 2 is positioned at handle 1 is provided with slip screens 13, handle 1 is provided with the fixedly screens 4 that cooperates slip screens 13 usefulness, and fixedly screens 4 prevents that rule 2 from skidding off outside the handle 1 when pulling, and fixedly screens 4 front ends are provided with an inclined plane, the inclined plane makes rule 2 readings convenient and accurate, handle 1 other end is equipped with knob 5, and 5 pairs of probe bodies 3 of knob lead and prevent that rule 2 from skidding off handle 1, and probe body 3 includes sleeve 7 and probe 8, wherein, sleeve 7 is assemblied in the movable span 6 of knob 5, and sleeve 7 is provided with anti-dislocation 12 with knob 5 contacted ends, and anti-dislocation 12 prevents that sleeve 7 from skidding off knob 5.Sleeve 7 surfaces are provided with skid resistant course, and skid resistant course can prevent effectively that sleeve 7 from skidding in use.Probe 8 is positioned at sleeve 7, and probe 8 needle end are provided with the shell fragment hook 9 of jag, and the shell fragment behind the described jag is linked up with 9 front ends and is parallel to each other.Probe 8 afterbodys are provided with screw thread 11, and be connected with the connecting hole 10 of rule 2 zero readings one end by screw thread 11, can change suitable probe 8 according to clinical needs, what present embodiment adopted is the probe 8 of measuring common bone hole depth, and rule 2 other ends extend to outside the handle 1.During use, left hand is held rule 2, and the right hand pinches the sleeve 7 of probe body 3, the right hand pushes away forward, and left hand pulls back, and draws shell fragment hook 9 in, probe body 3 is inserted in the bone hole, and left hand pushes away rule 2, and the right hand pinches sleeve 7 and pulls back, probe 8 ejects from sleeve 7 front ends and is parallel symmetric shell fragment hook 9, left hand draws the afterbody of rule 2 then, and shell fragment hook 9 just hangs on the cortex of side seam hole, handle 1 is pushed away forward again, reading scale, promptly is the bone hole depth.Left hand is held rule 2 and is pulled back, and the right hand pushes away sleeve 7 forward, draws shell fragment hook 9 in, and depth finder is withdrawed from the bone hole.Adopt the shell fragment hook of this programme to be difficult for slippage, easy to operate, and convenience is used, can be measured the bone hole depth fast and accurately.
