Abstract
The utility model discloses a tumor biopsy sampler, which comprises a needle core, a trocar, a negative pressure cylinder and an injector cylinder; the needle core and the needle core handle jointly form a sampling needle core, the sampling needle core and the needle core handle are connected through threads, a barb knife is arranged at the tail end of the needle core, a trocar is arranged outside the needle core, the trocar is connected with a cannula needle seat, the cannula needle seat is connected with a negative pressure cylinder through threads, and the negative pressure cylinder is connected with an injector through a hose; the tip end of the sleeve needle head is a blind end; the utility model discloses owing to set up the negative pressure section of thick bamboo device, can make tumour tissue easily cave in into the sample hole, made things convenient for the doctor to tumour tissue's sample operation, reduced the injury to patient's tissue.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically, and particularly a kind of tumor biopsy sampler.
Background technology
At present, cytolgical examination and histological examination method are generally adopted in clinical inspection to tumor.Cytolgical examination is to do inspection with the cell that fine needle is drawn affected area, and prior art generally adopts entry needle, has in the operation that negative pressure is big, the pin hole easy blocking, draws that thing is less, the depth is difficult for defectives such as grasp.And entry needle can't be done histological examination; When doing histological examination; Need cut the fritter tumor tissues through operation and check, still existing sampler is not owing to be with the negative pressure extracting device, and often the nook closing member sleeve pipe is thicker; Just can reach ideal sampling effect, this has brought great misery to the patient.
The utility model content
In order to solve deficiency of the prior art, this utility model provides a kind of tumor biopsy sampler.
The technical scheme that this utility model adopted is: a kind of tumor biopsy sampler comprises nook closing member, the trocar, negative pressure cylinder, syringe cylinder; Said nook closing member and needle core handle constitute the sampling nook closing member jointly; Through being threaded, the end of said nook closing member is provided with a barb cutter between the two, at the outside sheathed trocar of said nook closing member; The tip of the described trocar is the trocar tip of cecum; Near said trocar tip, have a rectangle thief hole, the end of the said trocar sleeve pipe needle stand of ining succession, said sleeve pipe needle stand is connected with negative pressure cylinder through screw thread; Said negative pressure cylinder is connected with a syringe through flexible pipe, and described negative pressure cylinder and syringe cylinder all are to be made by transparent macromolecular material.
The beneficial effect of this utility model is: compares with the sampling appliance of present use, and simple in structure, easy to use; And the negative pressure device that carries can make tumor tissues be easy in the recessed thief hole, and the handled easily personnel take a sample to tumor tissues, have exempted patient's free from suffering from operation, can be widely used in clinical.
Description of drawings
Fig. 1 is this utility model structural representation.
Fig. 2 is the nook closing member end construction sketch map of this utility model.
Among the figure: 1, trocar tip, 2, the barb cutter, 3, thief hole, 4, the trocar, 5, nook closing member, 6, flexible pipe, 7, circular dividing plate, 8, the round rubber diaphragm seal, 9, the sleeve pipe needle stand, 10, connect tube head, 11, negative pressure cylinder, 12, syringe cylinder, 13, needle core handle.
The specific embodiment
With reference to Figure of description this utility model is done following the detailed description:
A kind of tumor biopsy sampler comprises nook closing member 5, the trocar 4, negative pressure cylinder 11, syringe cylinder 12, and nook closing member 5 and needle core handle 13 common formation sampling nook closing members are between the two through being threaded; Head at nook closing member 5 is provided with barb cutter 2, and nook closing member 5 is enclosed within the trocar 4, and the front end of the trocar 4 is the trocar tip 1 of cecum, is provided with thief hole 3 near the trocar tip 1, and the trocar 4 is threaded with negative pressure cylinder 11 through sleeve pipe needle stand 9; Negative pressure cylinder 11 connects together with flexible pipe 6 and syringe cylinder 12 through connecting tube head 10.During use, at first confirm the degree of depth of diseased region, confirm depth of needle, behind skin degerming apart from body surface; Inserting needle vertically, confirmed the sample position after, promote needle core handle 13, round rubber diaphragm seal 8 tightly is attached on the circular dividing plate 7; Make to form an airtight space, use syringe cylinder 12 extracting airs then, make and form negative pressure in the negative pressure cylinder 11; Thereby tumor tissues is caved in in the thief hole 3, get a fritter tumor tissues with barb cutter 2 then, can accomplish the sampling operation of tumor tissues.This utility model can make tumor tissues be easy to depression and advance in the thief hole 3 owing to be provided with negative pressure cylinder 11, cuts the fritter tumor tissues thereby be easy to the doctor.
Claims (2)
1. a tumor biopsy sampler comprises nook closing member, the trocar, it is characterized in that: said tumor biopsy sampler is provided with negative pressure cylinder and the syringe cylinder that is used for extracting air.
