First end be installed on the second end of first handle 130, the first end of the second shell fragment 520 is installed on second handle.First
Second end of shell fragment 510 is provided with neck 511, and the second end of the second shell fragment 520 is provided with buckle convex 521, and buckle convex 521 is embedded at card
In groove 511；(not limited to this, it is also possible that the second end of the first shell fragment 510 is provided with buckle convex 521, the second of the second shell fragment 520
End is provided with neck 511, and buckle convex 521 is embedded in neck 511.) elastic force of the first shell fragment 510 and the second shell fragment 520 makes first
Handle 130 and second handle have the trend being located remotely from each other, but in the presence of limit convex 133, limit first handle 130 with
The maximum position that second handle is separated, the easy one hand of operating personnel is pinched first handle 130 and second handle makes the two phase
To rotating.
When carrying out tissue extraction, the first extraction unit 110 is spirally pierced in human body first, then pinched first-hand
Handle 130 and second handle simultaneously make the two relative rotation, and now, the drivening rod 400 of holding rod 300 makes connecting rod 400 with 220 turns of moving gear
Dynamic, due to the restriction effect of the second fluting 410, gear 220 remains the engagement with rack 411, and gear 220 drives outer
Pipe 200 rotates relative to inner core 100, and in the presence of spiral prominence and helicla flute, outer tube 200 is relative to inner core 100 in rotary shaft
Travelled forward on line, the circumgyration incision tissue of cutting blade 210, jagged cutting edge has " saw ", the effect of " cutting " tissue simultaneously, soon
Rapid-curing cutback is crisp to cut part tissue, and the tissue for making to cut is hidden and is contained in the first end of outer tube 200, then will hold first
Handle 130 and second handle integrally extract tissue extraction device outside human body out, because the first extraction unit 110 can prevent human body group
Knit and deviate from out of outer tube 200, now tissue is hidden to be contained in outer tube 200 and is carried over outside human body, unclamps first handle 130 and the
Two handles, under the effect of the elastic force of the first shell fragment 510 and the second shell fragment 520, the relative position of outer tube 200 and inner core 100 is recovered
Original state, now can remove extracted tissue and have detected, whole process is simple to operate, coherent, consumption
When it is short, mitigate the pain of patient.
Wherein, when clutching first handle 130 and second handle makes outer tube 200 advance, connecting rod 400 is relative to holding rod 300
Rotate, connecting rod 400 intersects with outer tube 200 and moved relative to outer tube 200, and the position-limiting action of the second fluting 410 makes
Rack 411 is intermeshed connecting rod 400 all the time with gear 220.The groove length of gear 220 can set appropriate surplus, make rack
411 can produce certain displacement upwards relative to rotary shaft of the gear 220 in gear 220, prevent rack 411 and gear 220
Beyond intermeshing scope.
The structure of first extraction unit 110 can also be the structure as shown in Figure 12 to 14：
As shown in figure 12, the first extraction unit 100 includes drill boom and drill bit, and drill bit is connected by drill boom with inner core, drill boom
Whole side be provided with spiral helicine extraction tank.
As shown in figure 13, it (is to include a drill boom shown in Figure 13 that the first extraction unit 100, which includes at least one drill boom,
Situation, but not limited to this), drill boom is flat, and flat drill boom integrally bending is hollow helical form, and drill boom surrounds hollow
Part is extraction chamber.Chamber is extracted as cylinder, drill boom flat horizontal surface is parallel with the axis of screw of drill boom or near parallel.Also, drill boom
First end be connected with inner core, the second end of drill boom is provided with warpage section, and the first end of warpage section is connected with the second end of drill boom,
Second end of warpage section is close to the central axis of extraction chamber.When spiral helicine drill boom pierces tissue, by part human body group
Knit and be wrapped in extraction intracavitary, reuse cutting blade 210 and its side is cut, make tissue and human body overall situation phase point
From can smoothly extract tissue.Also, the second end of drill boom is provided with warpage section, the first end of warpage section and drill boom
Second end is connected, and the second end of warpage section is close to the central axis of cylinder, is extracting inner core 100 and outer tube 200 out people
During body, it can prevent tissue from deviating from from the opening at the second end of drill boom, improve success rate of extracting.
As shown in figure 14, it (is the feelings for including a drill boom shown in Figure 13 that the first extraction unit, which includes at least one drill boom,
Condition, but not limited to this), drill boom is flat, and flat drill boom integrally bending is helical form, the flat horizontal surface and the axis of screw of drill boom
It is vertical or nearly vertical (flat horizontal surface of not limited to this or drill boom intersects with the axis of screw), and in the side of drill boom
Form spiral helicine extraction tank.When drill boom pierces human body, tissue enters in extraction tank, after the cutting of cutting blade 210, human body group
Knit and stay in extraction tank, when extracting inner core 100 and outer tube 200 out human body, the cell wall of extraction tank can provide stress surface, prevent people
Body tissue is deviate from, and easily takes tissue out of.
Not limited to this, it is also possible that after there is overhead structure, drill boom to be pierced into human body for the side of drill boom, tissue insertion
The recess of overhead structure, then cut with cutting blade, tissue extraction device is then extracted, is hooked using overhead structure and takes human body group out of
Knit.
