Abstract
The utility model discloses a tumor tissue biopsy puncture sampling device which comprises a suction cylinder and a sampling needle, wherein a piston is arranged in the suction cylinder, a pull rod is connected to the piston, and scales and an anti-sliding pad are arranged on the outer wall of the suction cylinder; the front end of the suction cylinder is connected with the rear end of the sampling needle; and the sampling needle is a hollow tube, at least one knife edge is arranged on the tube wall, scales are also arranged on the tube wall, and an anti-sliding sleeve is arranged at the rear end of the sampling needle, and is fixedly connected with the sampling needle. During use, when a tumor tissue is required to be punctured and sampled, an operator pinches the anti-sliding sleeve by fingers, stabs the sampling needle into a tumor gradually, and gently rotates the sampling needle when the sampling needle is stabbed into an appropriate position, so that the tumor tissue can be cut down by the knife edge; and then the anti-sliding pad on the suction cylinder is pinched by fingers, and the pull rod is pulled by the other hand, so that negative pressure is formed in the suction cylinder, and the cut-down tumor tissue is sucked into the suction cylinder. The tumor tissue biopsy puncture sampling device is convenient and easy to sample, can guarantee the sampling quality, causes little damage to a patient, and can be popularized and applied.
Description
Technical field
This utility model relates to a kind of tumor tissues biopsy puncture sampler.
Background technology
Human life and health in the tumor serious threat, and preoperative diagnosis result determines to be related to determining of operation plan.In clinical medicine work, have only by clear and definite clinical diagnosis and could instruct accurate clinical treatment, and will make clear and definite clinical diagnosis, often need puncture to obtain Pathologic specimen, make pathological diagnosis by check to Pathologic specimen.There is operation inconvenience in traditional puncture sampling, is difficult for sampling, sampling amount is little, to defectives such as patient trauma are big.
Summary of the invention
At above-mentioned prior art, this utility model provides a kind of tumor tissues biopsy puncture sampler, and it is easy to operate, sampling easily, and sampling amount is big, and is little to patient trauma.
This utility model is achieved through the following technical solutions:
A kind of tumor tissues biopsy puncture sampler comprises suction cylinder and sampling probe, is provided with piston in the suction cylinder, is connected with pumping rod on the piston, and the suction cylinder outer wall is provided with scale and slipmat; The suction cylinder front end is connected with the sampling probe rear end; Sampling probe is a hollow pipe, and tube wall is provided with at least one edge of a knife, also is provided with scale on the tube wall, and the sampling probe rear end is provided with anti-sliding sleeve, and anti-sliding sleeve is fixedlyed connected with sampling probe.
Described tube wall is provided with four edges of a knife.
Use: in the time of need puncturing sampling to tumor tissues, the operator pinches anti-sliding sleeve with finger, sampling probe is slowly thrust tumor, when waiting to thrust correct position, rotate sampling probe gently, then the edge of a knife can downcut tumor tissues, then with pointing the slipmat that pinches on the suction cylinder, another pulls moving pumping rod, then form negative pressure in the suction cylinder, with the tumor tissues that downcuts suck suction cylinder (effect of negative pressure also is: the tumor tissues that the edge of a knife does not downcut fully under suction function by tearing, and then be inhaled into sampling probe and suction cylinder), sampling is pulled up sampling probe and is got final product after finishing.Sampling probe is provided with anti-sliding sleeve, and the handled easily person is thrust tumor with sampling probe, is difficult for skidding, and the process of thrusting is steady, and sampling probe does not rock, and is little to the damage of tumor, reduces patient's misery.Sampling probe is provided with scale, can grasp the degree of depth of thrusting tumor.The edge of a knife on the sampling probe is used to downcut tumor tissues, is provided with a plurality of edges of a knife, can guarantee the sampling amount abundance.Suction cylinder is provided with slipmat, and convenient pulling pumping rod is difficult for skidding, and the pull process is steady, and sampling probe does not rock, and is little to the damage of tumor, reduces patient's misery.Suction cylinder is provided with scale, can grasp sampling amount.
Tumor tissues biopsy puncture sampler of the present utility model, sampling is convenient, sampling easily, sampling amount is guaranteed, and is little to patient trauma, can apply.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1, suction cylinder; 2, sampling probe; 3, piston; 4, pumping rod; 5, scale; 6, slipmat; 7, the edge of a knife; 8, anti-sliding sleeve.
The specific embodiment
Below in conjunction with embodiment this utility model is further described.
A kind of tumor tissues biopsy puncture sampler comprises suction cylinder 1 and sampling probe 2, as shown in Figure 1, is provided with piston 3 in the suction cylinder 1, is connected with pumping rod 4 on the piston 3, and suction cylinder 1 outer wall is provided with scale 5 and slipmat 6; Suction cylinder 1 front end is connected with sampling probe 2 rear ends; Sampling probe 2 is a hollow pipe, and tube wall is provided with four edges of a knife 7 (that is: have breach) on tube wall, and four edges of a knife 7 are interspersed, and also are provided with scale 5 on the tube wall, and sampling probe 2 rear ends are provided with anti-sliding sleeve 8, and anti-sliding sleeve 8 is fixedlyed connected with sampling probe 2.
Use: in the time of need puncturing sampling to tumor tissues, the operator pinches anti-sliding sleeve 8 with finger, sampling probe 2 is slowly thrust tumor, when waiting to thrust correct position, because sampling probe 2 is provided with the edge of a knife 7, tumor tissues can be clamp-oned in the edge of a knife, at this moment, rotate sampling probe 2 gently, then the edge of a knife 7 can downcut tumor tissues, with pointing the slipmat 6 that pinches on the suction cylinder 1, another pulls moving pumping rod 4 then, then forms negative pressure in the suction cylinder 1, with the tumor tissues that downcuts suck suction cylinder 1 (effect of negative pressure also is: the tumor tissues that the edge of a knife does not downcut fully under suction function by tearing, and then be inhaled into sampling probe 2 and suction cylinder 1), sampling is pulled up sampling probe 2 and is got final product after finishing.Sampling probe 2 is provided with anti-sliding sleeve 8, and the handled easily person is thrust tumor with sampling probe 2, is difficult for skidding, and the process of thrusting is steady, and sampling probe 2 does not rock, and is little to the damage of tumor, reduces patient's misery.Sampling probe 2 is provided with scale 5, can grasp the degree of depth of thrusting tumor.The edge of a knife 7 on the sampling probe 2 is used to downcut tumor tissues, is provided with a plurality of edges of a knife 7, can guarantee the sampling amount abundance.Suction cylinder 1 is provided with slipmat 6, and convenient pulling pumping rod 4 is difficult for skidding, and the pull process is steady, and sampling probe 2 does not rock, and is little to the damage of tumor, reduces patient's misery.Suction cylinder 1 is provided with scale 5, can grasp sampling amount.
