Abstract
The utility model provides a tumor sampling device. The tumor sampling device comprises a needle tube, a syringe needle, a piston, a piston rod, a reversed-hook-shaped cutting edge and a cutting edge rod, wherein the syringe needle is arranged at the front end of the needle tube and a sampling hole is formed in the side wall of the syringe needle; the piston is arranged in the needle tube and is connected with the piston rod; negative pressure is generated in the sampling hole under the pulling effect of the piston rod so as to suck tumor tissues into the sampling hole; a through cavity is formed between the piston rod and the piston; the cutting edge rod is arranged in the through cavity; the reversed-hook-shaped cutting edge is arranged at the front end of the syringe needle and is connected with the cutting edge rod so as to cut the tumor tissues sucked in the sampling hole under the pulling of the cutting edge rod. With the adoption of the manner, the tissue damage to a patient can be effectively reduced.
Description
Technical field
This utility model relates to field of medical technology, in particular to a kind of tumor sampler.
Background technology
As everyone knows, while carrying out body-surface tumor active check sampling to patient clinically, can successfully realize by operative incision, but the misery of bringing to patient due to operative incision is large, therefore the general syringe that adopts samples more at present, the negative pressure absorbing tumor tissues that relies on syringe to produce.But because the pin chamber of ordinary syringe syringe needle is narrower, only rely on negative pressure to be not easy to make tumor tissues to separate, therefore generally at the sidewall of syringe needle, overhead structure is set, to improve separating effect.But above-mentioned overhead structure easily damages patient's in-vivo tissue in the time that syringe needle takes out, and causes unnecessary misery to patient
In sum, be necessary to provide a kind of tumor sampler, to address the above problem.
Utility model content
The technical problem that this utility model mainly solves is to provide a kind of tumor sampler, to avoid that patient body inner tissue is caused to excessive damage.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: a kind of tumor sampler is provided, comprise needle tubing, syringe needle, piston, piston rod, barb-shaped blade, blade bar, syringe needle is arranged at the front end of needle tubing, on the sidewall of syringe needle, be provided with thief hole, piston is arranged in needle tubing and is connected with piston rod, to produce negative pressure under the pulling at piston rod at thief hole place, and then tumor tissues is sucked to thief hole, piston rod and piston are provided with cavity, blade bar is arranged in cavity, barb-shaped blade is arranged at the front end of syringe needle and is connected with blade bar, suck the tumor tissues of thief hole with cutting under the pulling at blade bar.
According to this utility model one preferred embodiment, thief hole is at least two, and arranges along the circumferential interval of syringe needle.
According to this utility model one preferred embodiment, the width of thief hole is along becoming gradually large from the front end of syringe needle to the direction of needle tubing.
According to this utility model one preferred embodiment, between blade bar and piston, sealing arranges.
According to this utility model one preferred embodiment, the lateral wall of barb-shaped blade contacts with the medial wall of syringe needle, and slides along the medial wall of syringe needle.
The beneficial effects of the utility model are: can in sampling process, only cut the tumor tissues that sucks thief hole by above-mentioned tumor sampler, avoid damaging its hetero-organization in patient body.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model tumor sampler one embodiment.
The specific embodiment
Below in conjunction with accompanying drawing 1 and embodiment, this utility model is elaborated.
Fig. 1 is the structural representation of this utility model tumor sampler one embodiment.As shown in Figure 1, the tumor sampler of the present embodiment comprises needle tubing 10, syringe needle 11, piston 12, piston rod 13, barb-shaped blade 14, blade bar 15.Syringe needle 11 is arranged at the front end of needle tubing 10, is provided with thief hole 111 on the sidewall of syringe needle 11.
In a preferred embodiment, thief hole 111 is at least two, and arranges along the circumferential interval of syringe needle 11.
In another preferred embodiment, the width of thief hole 111 is along becoming gradually large from the front end of syringe needle 11 to the direction of needle tubing 10.
Piston 12 is arranged in needle tubing 10 and is connected with piston rod 13, to produce negative pressure at thief hole 111 places under the pulling at piston rod 13, and then tumor tissues (not shown) is sucked to thief hole 111.Piston rod 12 and piston 13 are provided with cavity, and blade bar 15 is arranged in this cavity.
In a preferred embodiment, between blade bar 15 and piston 13, sealing arranges, to make can effectively producing negative pressure at thief hole 111 in the time that piston rod 13 pulls piston 13.
Barb-shaped blade 14 is arranged at the front end of syringe needle 11 and is connected with blade bar 15, sucks the tumor tissues of thief hole 111 with cutting under the pulling at blade bar 15.
In a preferred embodiment, the lateral wall of barb-shaped blade 14 contacts with the medial wall of syringe needle 11, and slides along the medial wall of syringe needle 11, and then improves the cutting effect of barb-shaped blade 14.
In sum, can in sampling process, only cut the tumor tissues that sucks thief hole by above-mentioned tumor sampler, avoid damaging its hetero-organization in patient body.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes this utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
