Safe tumor biopsy apparatus system less likely to cause bleeding

Abstract

The invention relates to a safe tumor biopsy apparatus system less likely to cause bleeding. The system is provided with a cystoscopy and an extractor; the cystoscopy is provided with a cystoscopy tube, an eye lens, a cold light source interface and a negative pressure connecting tube, and the inside of the cystoscopy tube is provides with an apparatus channel, an observation channel and a drainage channel; the extractor is provided with a parent cylinder, a daughter cylinder, a negative pressure attraction sphere and a sleeving component, the daughter cylinder is connected to the inside of the parent cylinder in a sleeving mode, the parent cylinder and the daughter cylinder can relatively freely slide, the negative pressure attraction sphere is arranged at the near end of the daughter cylinder, and the sleeving component is used for sleeving tumors which are attracted inside the far end of the daughter cylinder through the negative pressure attraction sphere along the outside of the daughter cylinder; in a work state, the extractor arrives at a focal part through the apparatus channel. The safe tumor biopsy apparatus system is not likely to cause bleeding after biospy, and is easy to study and easy to operate, minimally invasive, fast in postoperative recovery, simple in structure, low in cost and particularly suitable for biopsy of bladder neoplasms.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a safe and non-bleeding tumor biopsy device system. Background technique [0002] With the pollution of the environment and the aging of the population, there are more and more patients with various tumors clinically, which increases the medical burden on families and society. Tumor biopsy is a key step in judging benign and malignant tumors and formulating the next diagnosis and treatment plan. Existing tumor biopsy mainly involves partial resection, biting or puncture of the tumor, which has the following disadvantages: because the tumor has more blood vessels than normal tissues and grows rapidly, the above-mentioned biopsy operation often leads to postoperative bleeding, and additional treatment is required. Expensive hemostatic drugs are used and the hemostatic effect is inaccurate. The use of hemostatic drugs in some patients increases the risk of intravascular thr...

Problems solved by technology

However, in this utility model, the knife edge is only designed to be circular to facilitate filling and hemostasis after sampling, but it cannot fundamentally reduce biopsy bleeding, the effect is limited, and it is not suitable for tumor biopsy of the urinary system under a cystoscope.

[0004] In summary, there is an urgent need for a device that can effectively reduce intraoperative bleeding, is suitable for use under cystoscopy, and can quickly, efficiently, safely, and minimally invasively perform tumor biopsy. However, there are no related reports so far.
