Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, a kind of vertebral body sampling trepan for extracting sclerotin sample.
Background technology
For the pathologic feature of clear and definite Vertebral body, to the case of difficult diagnosis and need to accept the case of percutaneous vertebroplasty, need to use trepan to drill through vertebral body sclerotin row pathologic finding.But in clinical practice, in the case of pedicle punctures well, some patients still can not get vertebral body sclerotin, is unfavorable for clear and definite lesion nature.
Common ring drills through out the principle of vertebral body sclerotin: on the basis of pedicle punctures and sets up works fine passage, trepan is through service aisle rotary drilling 1-1.5 centimetre forward, now, containing one section of cylindrical sclerotin in trepan, its far-end is connected with other sclerotin Intrapyramidal；In the case of vertebral bone density is normal, due in trepan between sclerotin and trepan inwall frictional force relatively big, the most quickly extract trepan, typically cylindrical sclerotin far-end can be pulled off, thus take out sclerotin.But find in clinical position, some patients is more serious due to osteoporosis and vertebral bodies destroyed, its sclerotin pathological destruction, loose, thus and frictional force between trepan inwall reduce, the frictional force extracting trepan is not enough to pull off sample sclerotin, so bone piece can not be taken out carry out pathological examination.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, the vertebral body that easy to operate, sampling success rate is high samples trepan.
The present invention solves that technical problem be the technical scheme is that
Vertebral body of the present invention sampling trepan includes that lower end is provided with the drilling rod of drill bit, is arranged on the handle of drilling rod upper end, and described drill bit is tubular structure, and the lower end of drill bit is provided with detent projection, and described drilling rod is cylindrical structure, and the upper end of drilling rod is provided with external screw thread；Trocar sheath is sleeved on drilling rod, the upper end of described trocar sheath is fixedly connected with sleeve pipe lever, and described sleeve pipe lever is provided through hole, and described through hole is arranged with the coaxial of trocar sheath, through hole is provided with female thread, the external screw thread on described female thread coupling drilling rod；Described drill bit is made up of the arc lamellar body of at least two panels circular array, and the outer surface of described arc lamellar body is provided with the most gradually to the inclined-plane of contract；The edge of described handle is uniformly distributed multiple longitudinally disposed chute, the lower surface of slip lid is provided with multiple claw-plate corresponding to described chute, the end of claw-plate is provided with claw hook, described slip lid is positioned at the top of handle, described claw-plate is installed in chute, and the edge of described sleeve pipe lever is provided with the draw-in groove of coupling claw-plate.
Owing to have employed said structure, this vertebral body sampling trepan simple in construction, easy to use, sclerotin sample can be clamped during sampling, improve the success rate of sampling.

Detailed description of the invention
As shown in Figure 1 and Figure 2, vertebral body of the present invention sampling trepan includes that lower end is provided with the drilling rod 2 of drill bit 1, is arranged on the handle 3 of drilling rod 2 upper end, described drill bit 1 is tubular structure, the lower end of drill bit 1 is provided with detent projection, described drilling rod 2 is cylindrical structure, the end of drill bit 1 is resisted against on vertebral body sclerotin, the when that drilling rod 2 rotating, bone just can be cut a cannelure by the detent projection on drill bit 1, deepen this cannelure to 1-1.5 centimetre to form column sample, meet the requirement of sampling.
The upper end of drilling rod 2 is provided with external screw thread；Trocar sheath 4 is sleeved on drilling rod 2, the upper end of described trocar sheath 4 is fixedly connected with sleeve pipe lever 5, it is provided through hole on described sleeve pipe lever 5, described through hole is arranged with the coaxial of trocar sheath 4, through hole is provided with female thread, the external screw thread on described female thread coupling drilling rod 2, can be vertically moved on drilling rod 2 by screw thread when that sleeve pipe lever 5 rotating, sleeve pipe lever 5 vertically move and can drive trocar sheath 4 synchronizing moving, its lower end Pressing drill 1 when that trocar sheath 4 being descending.
Described drill bit 1 is made up of the arc lamellar body 6 of at least two panels circular array, the outer surface of described arc lamellar body 6 is provided with the most gradually to the inclined-plane 7 of contract, when trocar sheath 4 from top to bottom extrudes arc lamellar body 6 when, make arc lamellar body 6 to contract, hold sclerotin sample tightly, easily sclerotin sample root can be pulled off, improve the success rate of sampling.
As shown in Figure 2, Figure 4 shows, the edge of described handle 3 is uniformly distributed multiple longitudinally disposed chute 10, and the lower surface of slip lid 8 is provided with multiple claw-plate 9 corresponding to described chute 10, and the end of claw-plate 9 is provided with claw hook.Described slip lid 8 is positioned at the top of handle 3, and described claw-plate 9 is installed in chute 10, and the edge of described sleeve pipe lever 5 is provided with the draw-in groove 11 of coupling claw-plate 9, is provided with the groove of coupling claw hook in draw-in groove draw-in groove 11.Handle 3 is aligned with sleeve pipe lever 5, make claw-plate 9 just to draw-in groove 11, claw-plate 9 is made to slip in draw-in groove 11 8 times pressures of slip lid, until claw hook sticks in groove, now by claw-plate 9, handle 3 can be linked together with sleeve pipe lever 5, make trocar sheath 4 and drilling rod 2 synchronous rotary, for cutting out annular incision on bone；After having cut, extract slip lid 8, claw-plate 9 is made to exit from draw-in groove 11, can be separated with sleeve pipe lever 5 by handle 3, pin handle 3, revoling tube lever 5 makes sleeve pipe lever 5 downward spiral move, the lower end extruding arc lamellar body 6 of trocar sheath 4 makes it to contract, hold sclerotin sample tightly, then hold handle 3 and sleeve pipe lever 5, upwards extract and sample root can be pulled off, take out sample.
