Description

Blood tumor biopsy sampler

Technical Field

The utility model relates to the technical field of medical equipment, specifically a blood tumor biopsy sampler.

Background

The early detection, the correct diagnosis and the timely treatment have important influence on the prognosis of the tumor, the accuracy of tumor diagnosis is gradually improved along with the continuous improvement of examination means and methods in recent years, but a large part of tumors still have no typical imaging characteristics, so that the simple imaging technology examination has the problem of difficult diagnosis, and the accurate diagnosis needs three combinations of clinic, image and pathology, wherein the pathological diagnosis plays a key role in the selection of a treatment scheme, and the needle biopsy is a main way for obtaining the pathological diagnosis result.

At present, most of samplers adopted for blood tumor biopsy adopt a needle head to suck, and then are taken out to carry out assay; however, most of the existing needles are designed into a whole with the needle cylinder, the needle cylinder cannot be detached and replaced, and the needle cylinder is cleaned and disinfected and then is used continuously, so that the needle cylinder needs to be replaced when the needle cylinder is replaced, the medical equipment is wasted, and the sampler for simultaneously sucking blood tumors can pollute the environment after being discarded, so that certain improvement is needed.

An object of the utility model is to provide a blood tumor biopsy sampler to solve the problem among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a blood tumour biopsy sampler, includes the sampler body, the sampler body is formed by cylinder, installation head, connecting rod and rear end cap combination, cylinder one end is provided with the installation head, the cylinder other end is provided with the rear end cap, the installation head is connected through the screw hole meshing of the external screw thread of an outer wall and cylinder one end, the rear end cap is connected through the screw hole meshing of the external screw thread on the outer wall of one end and cylinder one end, be provided with the sleeve on the cylinder outer wall, the sleeve passes through the internal thread on the inner wall and is connected with the external screw thread meshing on the cylinder, the inside sealing plug that is provided with of cylinder, sealing plug outer wall one side is provided with the connecting.

Preferably, the installation outer wall is provided with an anti-skid edge A.

Preferably, the outer wall of the rear end cover is provided with an anti-slip rib B.

Preferably, the outer wall of the needle cylinder is provided with scales.

Preferably, one end of the mounting head is provided with a needle.

Preferably, the two sides of the outer wall of the sleeve are both provided with connecting plates.

Compared with the prior art, the beneficial effects of the utility model are that: through the setting of installation head and rear end cap, the installation head is connected with the screw hole meshing of cylinder one end through the external screw thread on the one end outer wall, and the rear end cap is connected with the screw hole meshing of cylinder one end through the external screw thread on the one end outer wall, makes installation head and rear end cap conveniently install and dismantle, conveniently changes after installation head uses once, and cylinder, sealing plug and rear end cap conveniently wash simultaneously and disinfect and carry out repetitious usage, practice thrift medical supplies's use. The utility model discloses a setting of a series of structures conveniently installs and dismantles, and some parts can wash simultaneously and disinfect and carry out repetitious usage, practice thrift medical supplies's use.
