Description
Technical field
The present invention relates to a kind of medical instrument, specifically a kind of Medical orthopedic for extracting lesion sclerotin sample takes
Sample trepan.
Background technology
For the pathologic feature of clear centrum bone lesion, case to difficult diagnosis and need to receive percutaneous puncture centrum
The case of plasty needs to drill through centrum sclerotin row pathologic finding using trepan.But in clinical application, punctured in pedicle
In the case of good, some patientss cannot still get centrum sclerotin, be unfavorable for clear lesion nature.
Commonly the principle of trepan taking-up 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 case of centrum bone density is normal, 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.
Invention content
The object of the present invention is to provide a kind of centrums simple in structure, easy to operate, that sampling success rate is high to sample trepan.
The present invention is for technical scheme applied to solve the technical problem：
Lesion sclerotin sampling trepan of the present invention includes that lower end is equipped with the drilling rod of drill bit, the hand in drilling rod upper end is arranged
Handle, the drill bit are tubular structure, and the lower end of drill bit is provided with detent projection, and the drilling rod is cylindrical structure, drilling rod
Upper end is rotatably connected to the center of handle, and in the upper end of drilling rod, connection is greater diameter than the disk of drilling rod, disk insertion
In handle；Outer tube is sleeved on drilling rod, the spline between the outer wall of the drilling rod and the inner wall of outer tube by axially sliding
Cooperation；The upper end of the outer tube is fixedly connected with casing lever, and clutch is provided between described sleeve pipe lever and handle；
The drill bit is made of at least two panels arc sheet body arranged in a ring, the outer surface of the arc sheet body be equipped with from bottom to top by
Gradually to the inclined-plane of contract.
The clutch includes the upper magnetic ring for being separately mounted to handle and casing lever relative position and lower magnet ring, described
It is provided with cam ring on handle, cam path is provided on described sleeve pipe lever, the cam ring is that one section of height becomes from high to low
The fan-shaped boss of change, the cam path are width matching cam ring annular grooves, and the depth of the cam path changes from deep to shallow.
The inner wall of the outer tube carries the fin being axially distributed, and the outer surface of the drilling rod is equipped with the bar shaped of matching fin
Keyway, the fin are mounted in keyway.
Lesion sclerotin sampling trepan is simple in structure, easy to use due to the above structure, and when sampling can clamp
Sclerotin sample improves the success rate of sampling.
Description of the drawings
Fig. 1 is the structural schematic diagram of one embodiment of the invention.
Fig. 2 is the A-A sectional views of Fig. 1.
Fig. 3 is the upward view of handle.
Specific implementation mode
As shown in Figure 1, it includes that lower end is equipped with the drilling rod 2 of drill bit 1, setting exists that lesion sclerotin of the present invention, which samples trepan,
The handle 3 of 2 upper end of drilling rod, the drill bit 1 are tubular structure, and the lower end of drill bit 1 is provided with detent projection, and the drilling rod 2 is
The lower end of drill bit 1 is resisted against on centrum sclerotin by cylindrical structure, and detent projection when drilling rod 2 rotates on drill bit 1 is just
Bone can be cut an annular groove, which is deepened to form column sample to 1-1.5 centimetres, meets sampling
It is required that.
As shown in Figure 1, the upper end of drilling rod 2 is rotatably connected to the center of handle 3, connected always in the upper end of drilling rod 2
Diameter is more than the disk of drilling rod 2, and the disk is embedded in handle 3, drilling rod 2 can be not only connected to the center of handle 3 in this way but also can
So that drilling rod 2 rotates freely.Outer tube 4 is sleeved on drilling rod 2, is passed through between the outer wall and the inner wall of outer tube 4 of the drilling rod 2
The spline fitted axially slid, makes only to slide axially between drilling rod 2 and outer tube 4, can not relative rotation.Concrete scheme, can
To carry the fin 41 being axially distributed in the inner wall of the outer tube 4, the outer surface of the drilling rod 2 is equipped with the item of matching fin 41
Shape keyway, the fin 41 are mounted in keyway.Certainly, the quantity of fin 41 and keyway can be arranged as required to.It is described outer
The upper end of casing 4 is fixedly connected with casing lever 5, and clutch is provided between described sleeve pipe lever 5 and handle 3, the clutch
The effect of mechanism is can to change the distance between casing lever 5 and handle 3；The drill bit 1 is arranged in a ring by least two panels
Arc sheet body 6 constitute, the outer surface of the arc sheet body 6 is equipped with from bottom to top gradually to the inclined-plane of contract 7.Work as outer tube
4 when from top to bottom squeeze inclined-plane 7 of arc sheet body 6, makes arc sheet body 6 to contract, holds sclerotin sample tightly, can hold very much
It changes places and pulls off sclerotin sample root, improve the success rate of sampling.
The clutch includes the upper magnetic ring 31 for being separately mounted to 5 relative position of handle 3 and casing lever and lower magnet ring
51, upper magnetic ring 31 and lower magnet ring 51 are mutually attracted by magnetic force.As shown in figure 3, cam ring 32 is provided on the handle 3, institute
It is the fan-shaped boss that one section of height changes from high to low to state cam ring 32.As shown in Fig. 2, being provided on described sleeve pipe lever 5 convex
Race 52, the cam path 52 are width matching 32 annular grooves of cam ring, and the depth of the cam path 52 changes from deep to shallow.
When without outer force effect, handle 3 and casing lever 5 are pulled together by upper magnetic ring 31 and lower magnet ring 51 by magnetic force, cam
Ring 32 is embedded in cam path 52, and the 52 deeper place of high-end embedded cam path of cam ring 32, makes handle 3 and casing lever
Gap between 5 is minimum, and outer tube 4 is located at a high position at this time；Rotating handle 3, by the high-end relatively deep by cam path 52 of cam ring 32
Place to shallower place sliding, cam ring 32 can push 4 downlink of outer tube, 4 lower end of outer tube of downlink to pass through inclined-plane 7
Arc sheet body 6 is squeezed to contract.At this time if there is sample cylinder in 1 inner cavity of drill bit, the arc sheet body 6 of contraction can hold bone tightly
Then matter sample holds handle 3 and casing lever 5, sample root can be pulled off upwards by extracting, and take out sample.
