Description
Technical field
The present invention relates to a kind of medical instrument, specifically a kind of medical test orthopaedics sampler.
Background technique
For the pathologic feature of clear Vertebral body, case to difficult diagnosis and need to receive percutaneous puncture vertebral plasty
The case of art needs to drill through centrum sclerotin row pathologic finding using trepan.But it in clinical application, is punctured in pedicle good
In the case where, some patientss cannot still get centrum sclerotin, be unfavorable for clear lesion nature.
The principle that common trepan takes out centrum sclerotin is: on the basis of works fine channel is established in pedicle puncture,
Trepan is through service aisle 1-1.5 centimetres of rotary drilling forward, at this point, containing one section of cylindrical sclerotin, distal end in trepan
It is connected with other Intrapyramidal sclerotin；In the normal situation of centrum bone density, due to rubbing between sclerotin and trepan inner wall in trepan
Power is larger, quickly extracts trepan at this time, can generally pull off cylindrical sclerotin distal end, to take out sclerotin.But in clinical work
It is found in work, some patientss are sclerotin pathological destruction, loose since osteoporosis and vertebral bodies destroyed are more serious, thus and ring
The frictional force bored between inner wall reduces, and the frictional force for extracting trepan is not enough to pull off sample sclerotin, so bone block progress cannot be taken out
Pathological examination.

Specific embodiment
As shown in Figure 1 and Figure 2, medical test orthopaedics sampler of the present invention includes the drilling rod that one end is equipped with drill bit 1
2, the handle 3 being connected on drilling rod 2, the drill bit 1 are tubular structure, and the end of drill bit 1 is provided with detent projection, by drill bit 1
End be resisted against on centrum sclerotin, drilling rod 2 rotate when drill bit 1 on detent projection can by bone cut a ring
The annular groove is deepened that column sample can be formed to 1-1.5 centimetres, meets the requirement of sampling by shape slot.
The other end of the drilling rod 2 is equipped with and takes bone pipe 4, and described to take bone pipe 4 be the tubular structure for matching drill bit 1, takes bone pipe 4
Inner wall be distributed multiple hangnails 5 in a ring, the bottom of the hangnail 5 is connected in the through hole for being opened in and taking on 4 tube wall of bone pipe,
The top of hangnail 5 is to the interior cavity dumping for taking bone pipe 4；The axial location of drilling rod 2 is provided with polygon prism shape chamber, the handle 3
Lower end is fixedly connected with the polygon prism shape pipe 6 being inserted into polygon prism shape chamber.The shape of polygon prism shape pipe 6 and polygon prism shape chamber and
Size matches, and polygon prism shape pipe 6 can be inserted or extract, and can drive drilling rod 2 when the rotation of polygon prism shape pipe 6
It rotates together.
The connection of polygon prism shape pipe 6 and polygon prism shape chamber can rely solely on friction fit.It can also be such as Fig. 3, Fig. 4 institute
Show, push-pull rod 7 is provided in the inner cavity of the polygon prism shape pipe 6, and the upper end of the push-pull rod 7 passes through handle 3 and is fixedly connected on
On pressing plate 8, push-pull rod 7 can be pulled to move axially by pressing plate 8.The lower end of polygon prism shape pipe 6 is hinged with flip body 9, described
The lower end of push-pull rod 7 is hinged on flip body 9 by swing rod 10.
The upper end of the handle 3 is equipped with groove 11, be provided in the groove 11 can vertical sliding motion pressing plate 8, pressing plate 8
Shape and the shape of groove 11 match, and can be circle, are also possible to square, and the side wall of groove 11 is equipped with and can laterally stretch
It contracts and stops the lock tongue 12 of 8 vertical sliding motion of pressing plate, when pressing plate 8 is lifted to a high position, lock tongue 12 is inserted under pressing plate 8
Face prevents 8 downlink of pressing plate；Conversely, lock tongue 12 is inserted into the upper surface of pressing plate 8 when pressing plate 8 goes downwards to low level, can prevent
Pressing plate 8 rebounds.
The section of the lock tongue 12 is rectangle, and for lock tongue 12 through being inserted on the side wall of groove 11, the outer end of lock tongue 12 is solid
Determine attended operation button 13, the middle section of lock tongue 12 has fin 14, and the fin 14 is fitted in fin sliding bin, described convex
Rib sliding bin is the rectangular cylindrical cavity being arranged in the side wall of groove 11.The movement of fin 14 is limited in fin sliding bin
In, it can surprisingly fall off, lose to avoid lock tongue 12.Operating knob 13 is extracted outward, and lock tongue 12 is displaced outwardly and is retracted into fin and slides
It moves in storehouse, unrestricted can according to need of pressing plate 8 is vertically moved up or down in groove 11 at this time；After the movement in place of pressing plate 8, pressing
Operating knob 13 makes the inner end of lock tongue 12 reach the upper surface of pressing plate 8 or below can lock the position of pressing plate 8.
The lower end of the polygon prism shape pipe 6 is hinged with flip body 9, and the lower end of the push-pull rod 7 is hinged on by swing rod 10
On flip body 9.
The polygon prism shape pipe 6 is the stylostome that section outer profile is square, and the flip body 9 is symmetrically arranged two
Block rectangular block shape structure, the outside of flip body 9 are hinged on the outer wall of polygon prism shape pipe 6, the hinged swing rod 10 in the inside of flip body 9
Lower end, the upper end of the swing rod 10 is hinged on push-pull rod 7.As shown in figure 3, passing through pendulum when push-pull rod 7 is located at high-order
Bar 10 pulls up the inside of flip body 9, and two flip bodies 9 close up the cylinder to be formed as 6 outer profile of polygon prism shape pipe, not shadow
Ring the sliding axially in polygon prism shape chamber of polygon prism shape pipe 6；As shown in figure 4, passing through pendulum when push-pull rod 7 is located at low level
Bar 10 pushes down on the inside of flip body 9, and two flip bodies 9 are stuck in the end face of polygon prism shape chamber to 90 degree of two side to overturn respectively
On, by polygon prism shape pipe 6, position is locked in polygon prism shape chamber, so that drilling rod 2 is locked on polygon prism shape pipe 6.
In use, making to pass through handle 3 on the polygon prism shape pipe 6 that drill bit 1 is downward, bone pipe 4 is taken upwards to be mounted on drilling rod 2
Rotary drilling-head 1 cuts endless groove on bone, and continues ring cutting, until the sampling that the depth of endless groove reaches 1-1.5 centimetres is wanted
It asks；Then remove drilling rod 2, make to take after overturning bone pipe 4 downwards, on the polygon prism shape pipe 6 that is upwards mounted on drilling rod 2 of drill bit 1, and
Pressing plate 8 is pushed, push-pull rod 7 is made to be located at low level, drilling rod 2 is locked on polygon prism shape pipe 6, taking bone pipe 4 to put in endless groove
Bottom, since hangnail 5 has certain elasticity, the top of hangnail 5 is resisted against the root of sample cylinder, increase take bone pipe 4 with
The frictional force of sample cylinder, extracting drilling rod 2 at this time can pull off sample and take out.Bone pipe 4 can also be taken to utilize by rotation
Hangnail 5 cuts out root annular groove in the root of sample, then extracts drilling rod 2 again.
