Specific embodiment

It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

It please refers to shown in Fig. 1-4, a kind of tumor sampling device, including first sleeve 1, the top of first sleeve 1, which is equipped with, to be taken Sample portion 5, sampling portion 5 include several sample spoons 13, and closure forms hemispherical between sample spoon 13, and the bottom end of sample spoon 13 is all provided with Have a link block 7, the top of first sleeve 1 is equipped with groove, and the bottom end of link block 7 is arranged in groove, and by rotation axis with it is recessed Slot rotation connection.

In use, the bottom end due to sample spoon 13 is rotatablely connected by the top of link block 7 and first sleeve 1, take Sample spoon 13 can be rotated centered on rotation axis, realize hemispheric folding.

The inside of sample spoon 13 is cavity, and the left and right sidewall of sample spoon 13 is equipped with square hole 8, is equipped with and shrinks in sample spoon 13 Device 14.

Wherein, constriction device 14 includes several loop-drives 9, is connected between the outer end of loop-drive 9 by the first spring 10, loop-drive It is equipped with guide rail 12 in the middle part of 9 inner end, is equipped with sliding block 11 in guide rail 12, is connected between guide rail 12 and sliding block 11 by second spring, The other end of sliding block 11 is connect with cylinder 6, and the top of cylinder 6 is equipped with limited block 15.

Wherein, the quantity of sample spoon 13 is 3, and the quantity of loop-drive 9 is 3, and the first spring 10 is arranged in cavity, and guide rail 12 is set It sets between sample spoon 13.

In use, guide rail 12 is arranged between sample spoon 13, and sample spoon 13 since the first spring 10 is arranged in cavity Left and right sidewall be equipped with square hole 8, therefore loop-drive 9 is then arranged in the cavity of sample spoon 13 by square hole 8.

Since the sliding block 11 in guide rail 12 is connect with cylinder 6, and between sample spoon 13, closure forms hemispherical, works as contraction When device 14 is located at the bottom end of sample spoon 13, second spring keeps original state, and remains closed between sample spoon 13

It controls constriction device 14 by cylinder 6 to travel forward along first sleeve 1, at this time the circle due to being formed between cavity All diameters become smaller, and the relative position between loop-drive 9 is constant, thus sample spoon 13 will to be rotated centered on rotation axis so that It is opened between sample spoon 13.

By position of the control cylinder 6 in first sleeve 1, the different degrees of folding of sample spoon 13 is realized, it is final to realize Control the purpose of sample size.

Wherein, the coefficient of elasticity of second spring is 4 times of first the elastic coefficient.

Therefore in use, with 6 position of cylinder change, second spring can be slightly compressed, and sliding block 11 is by direction guiding rail 12 Interior movement further increases the flexibility of sample spoon 13.

First sleeve 1 is set in second sleeve 2, and the outer wall top of second sleeve 2 is equipped with screw thread, the top of second sleeve 2 End has been connected through a screw thread 3rd sleeve 3, and the top of 3rd sleeve 3 is equipped with circular hole 4, and sampling portion 5 is derivative to third by circular hole 4 The apical lateral of sleeve 3.

Wherein, cylinder 6 extends to the outer end of first sleeve 1.

Wherein, the size diameter of circular hole 4 is greater than the diameter of sample spoon 13.

In use, since first sleeve 1 is set in second sleeve 2, and cylinder 6 extends to the outer end of first sleeve 1, because This can by using sample spoon 13 sample after, by by first sleeve 1 take out second sleeve 2, by print by taking body out of in vivo Outside, and cancer cell is avoided to infect channel.

One specific embodiment of the utility model are as follows:

In use, sample spoon 13 can be moved to first to the top (as shown in Figure 1) of 3rd sleeve 3, into disease affected part, Second sleeve 2,3rd sleeve 3 are moved backward, gives 1 top sample spoon of first sleeve 13 enough sampler spaces, passes through control Constriction device 14 processed controls the openings of sizes of sample spoon 13.

The extent of opening of sample spoon 13 is higher, and sampling block product specification also increases accordingly, and opens and is open when sample spoon 13 Afterwards, affected part is sampled by the tip of sample spoon 13, after sampling, extent of opening is slightly turned down, realized to circular hole 4 Card and.

Since the top of second sleeve 2 has been connected through a screw thread 3rd sleeve 3, card and rear rotatably 3rd sleeve 3, After unscrewing, further the extent of opening of sample spoon 13 is reduced, after clamping print, is retracted in second sleeve 2, and with second Sleeve 2 leaves patient's body, and 3rd sleeve 3 will be left at the surface of a wound, for reducing oozing of blood.
