Throat tumor sampling device

Abstract

The invention discloses a throat tumor sampling device. The bottom of the machine body is fixedly provided with a grip, the grip is internally and fixedly provided with a negative pressure module, the machine body is internally and slidably connected with an outer needle cylinder, the back surface of the outer needle cylinder is fixedly provided with a driving frame, the outer needle cylinder is internally and fixedly provided with a square flow cavity, and the inner wall of the square flow cavity is fixedly provided with a bracket; a transmission inner cylinder is slidably connected to the inner wall of the support, a conveying core pipe is slidably connected to the inner wall of the transmission inner cylinder, and a transmission mechanism matched with the transmission inner cylinder and the conveying core pipe is fixedly arranged on the back face of the driving frame. Through the design of the structures of the outer needle cylinder, the sampling sealing knives and the like, the device can efficiently complete the sampling work of the throat tumor in a minimally invasive puncture mode, and during the sampling work of the device, through the design of the double sampling sealing knives, the tumor tissue can be effectively cut off when the tumor tissue is sampled.

Description

technical field [0001] The invention relates to the technical field of medical aids, in particular to a throat tumor sampling device. Background technique [0002] Tumor is an abnormal lesion formed by clonal abnormal proliferation of a certain cell in the local tissue under the action of various carcinogenic factors. For tumors, pathological analysis of tumors requires sampling and analysis of the interior of the tumor. [0003] In the early stage of tumor sampling, the tumor was partially incised with a scalpel, and then relevant sampling tools were used for sampling. The incision was large and the sampling process was painful. In the prior art, various styles of minimally invasive tumor sampling devices have appeared. For example, the patent document with publication number CN114129197A discloses a postoperative sample sampling device in oncology department. The device is provided with a clamping mechanism and a card. The sampling mechanism is used to access the extract...

Problems solved by technology

[0003] In the early stage of tumor sampling, the tumor part was often cut open with a scalpel, and then related sampling tools were used for sampling. The wound was large and the sampling process was painful. advantages, in the prior art, there have been various types of tumor minimally invasive sampling devices, such as the patent document with the publication number CN114129197A disclosing a kind of postoperative specimen sampling device for oncology, which is provided with a clamping mechanism and a card Positioning mechanism, through the clamping mechanism to access the extracted samples, and then press the clamping mechanism to clamp the clamping mechanism, avoiding the influence of sampling during the operation of the clamping mechanism, but the above-mentioned sampling device cannot be effectively realized during sampling. The work of cutting tumor tissue and retaining samples leads to a low sampling success rate of the sampling device. At the same time, the above-mentioned sampling device is inconvenient to quickly clean and disinfect the inner wall of the sampling mechanism after sampling. Based on this, the present invention provides a Throat tumor sampling device, to solve the problems raised in the above-mentioned background technology
