Detailed description of the invention
As shown in Figure 1 and Figure 2, medical sclerotin sampling trepan of the present invention comprises one end and is provided with the drilling rod 2 of drill bit 1, the handle 3 be connected on drilling rod 2, described drill bit 1 is tubular structure, the end of drill bit 1 is provided with detent projection, the end of drill bit 1 is resisted against on vertebral body sclerotin, bone just can be cut a cannelure by detent projection time drilling rod 2 rotates on drill bit 1, is deepened by this cannelure can form column sample to 1-1.5 centimetre, meets the requirement of sampling.
The other end of described drilling rod 2 is provided with gets bone pipe 4, described bone pipe 4 of getting is the tubular structures mating drill bit 1, the inwall getting bone pipe 4 distributes multiple agnail 5 ringwise, and the bottom of described agnail 5 is connected in the through hole being opened in and getting on bone pipe 4 tube wall, and the top of agnail 5 is to getting cavity dumping in bone pipe 4; The axial location of drilling rod 2 is provided with polygon prism shape chamber, and the lower end of described handle 3 is fixedly connected with the polygon prism shape pipe 6 be inserted in polygon prism shape chamber.Polygon prism shape pipe 6 matches with the shape and size in polygon prism shape chamber, and polygon prism shape pipe 6 can insert or extract, and drilling rod 2 can be driven to rotate together time polygon prism shape pipe 6 rotates.
Polygon prism shape pipe 6 only can rely on friction fit with the connection in polygon prism shape chamber.Also as shown in Figure 3, Figure 4, can be provided with push-pull bar 7 in the inner chamber of described polygon prism shape pipe 6, the upper end of described push-pull bar 7 is fixedly connected on pressing plate 8 through handle 3, push-pull bar 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, and the lower end of described push-pull bar 7 is hinged on flip body 9 by fork 10.
The upper end of described handle 3 is provided with groove 11, being provided with in described groove 11 can the pressing plate 8 of vertical sliding motion, the shape of pressing plate 8 and the mating shapes of groove 11, can be circular, also can be square, the sidewall of groove 11 be provided with and can contracts and stop the dead bolt 12 of pressing plate 8 vertical sliding motion, when pressing plate 8 is lifted to a high position time by lateral extensometer, dead bolt 12 is inserted into below pressing plate 8, stops pressing plate 8 descending; Otherwise dead bolt 12 is inserted into above pressing plate 8 when pressing plate 8 goes downwards to low level time, pressing plate 8 can be stoped to rebound.
The cross section of described dead bolt 12 is rectangle, dead bolt 12 run through be inserted into groove 11 sidewall on, the outer end of dead bolt 12 is fixedly connected with operating knob 13, the stage casing of dead bolt 12 is with fin 14, described fin 14 cooperation is arranged in fin sliding bin, and described fin sliding bin is the rectangular cylindrical cavity be arranged in the sidewall of groove 11.The movement of fin 14 is limited in fin sliding bin, can avoid dead bolt 12 accidental, loss.Outwards extract operating knob 13, dead bolt 12 outwards moves and is retracted in fin sliding bin, and now pressing plate 8 is unrestricted can vertical lift in groove 11 as required; After pressing plate 8 moves into place, what pressing operation button 13 made the inner of dead bolt 12 reach pressing plate 8 above or below can by the locking position of pressing plate 8.
The lower end of described polygon prism shape pipe 6 is hinged with flip body 9, and the lower end of described push-pull bar 7 is hinged on flip body 9 by fork 10.
Described polygon prism shape pipe 6 is cross section outlines is foursquare stylostome, described flip body 9 is symmetrically arranged two pieces of rectangular block shape structures, the outside of flip body 9 is hinged on the outer wall of polygon prism shape pipe 6, the lower end of the hinged fork 10 in inner side of flip body 9, the upper end thereof of described fork 10 is on push-pull bar 7.As shown in Figure 3, time push-pull bar 7 is positioned at a high position, by the inner side pull-up of fork 10 by flip body 9, two flip bodies 9 close up the formation cylinder the same with polygon prism shape pipe 6 outline, do not affect polygon prism shape pipe 6 sliding axially in polygon prism shape chamber; As shown in Figure 4, time push-pull bar 7 is positioned at low level, pushed away downwards by the inner side of fork 10 by flip body 9, two flip bodies 9 turn on the end face that turn 90 degrees and be stuck in polygon prism shape chamber respectively to both sides, by polygon prism shape pipe 6 locking position in polygon prism shape chamber, thus drilling rod 2 is locked on polygon prism shape pipe 6.
During use, make drill bit 1 downwards, get on polygon prism shape pipe 6 that drilling rod 2 is upwards arranged on by bone pipe 4, on bone, cut endless groove by handle 3 rotary drilling-head 1, and continue ring cutting, until the degree of depth of endless groove reaches the sampling requirement of 1-1.5 centimetre; Then drilling rod 2 is taken off, make after upset to get bone pipe 4 downwards, on the polygon prism shape pipe 6 that upwards drilling rod 2 is arranged on of drill bit 1, and pressing plate 8 is pressed down, make push-pull bar 7 be positioned at low level, drilling rod 2 is locked on polygon prism shape pipe 6, the bottom of getting bone pipe 4 and put in endless groove, because agnail 5 has certain elasticity, the top of agnail 5 is resisted against the root of sample cylinder, and increase the frictional force of getting bone pipe 4 and sample cylinder, now extracting drilling rod 2 can pull off sample and take out.Also can get bone pipe 4 by rotation utilizes agnail 5 to cut out root annular groove at the root of sample, and then extracts drilling rod 2.
