Description

Technical Field

[0001] The utility model relates to an integrated device for endoscopic biopsy and brushing, belonging to the technical field of medical equipment. Background Art

[0002] With the continuous enhancement of people's health awareness and the continuous improvement of modern medical diagnosis and treatment, gastrointestinal endoscopy has been included in the routine physical examination items of many groups. The detection rate of early cancer and tumors has also increased significantly, and the phenomenon of "two-level differentiation" has become more and more obvious.

[0003] Early cancer is difficult to identify under endoscopy due to its hidden lesions. Even if it is identified and tracked early, it is easy to be ignored due to the low positive rate of lesion biopsy. However, at this time, many cancer cells have fallen off the mucosal surface. If it is supplemented by cell exfoliative cytology and combined with pathological examination, a clear diagnosis can be made, and early detection and early treatment can be achieved. Due to the hidden disease and late discovery of patients with advanced tumors, endoscopic examinations are usually prone to poor exposure of tumor tissue due to tumor growth, lumen distortion, and excessive traction angles. This is especially true for patients with biliary tract lesions. Pathological biopsy and cell brushing are difficult. Therefore, there is an urgent need for an integrated device for endoscopic biopsy and exfoliated cell brushing to assist clinical endoscopists in endoscopic diagnosis, biopsy, and brushing. Utility Model Content

[0004] The technical problem to be solved by the utility model is that biopsy and brushing examination cannot be performed synchronously during existing clinical examinations, resulting in low detection efficiency and increased pain for patients.

[0010] Furthermore, the cell brush assembly includes a guide rope, a control bracelet and a brush bristle portion. One end of the guide rope passes through a brush inspection tube and extends into the brush inspection cavity, and the other end is located outside the brush inspection tube. The control bracelet is fixed to the end of the guide rope extending outside the brush inspection tube and is used to control the sliding of the guide rope along the length direction of the brush inspection cavity. The brush bristle portion is arranged at the end of the guide rope extending into the biopsy cavity and extends out or extends into the brush inspection cavity as the guide rope slides.

In this embodiment, the use and installation of the rotatable biopsy forceps 2 are both prior art and will not be described in detail.

[0024] In a further embodiment, one end of the endoscope tube body 1 equipped with a handle 23 is provided with a biopsy tube 4 and a brush inspection tube 5, which are integrally injection molded with the endoscope tube body 1, the biopsy tube 4 is connected to the biopsy cavity 11, the hose 22 passes through the biopsy tube 4 and extends into the biopsy cavity 11, one end of the handle 23 is fixedly inserted in the biopsy tube 4, the slip ring 24 is slidably installed on the handle 23 to control the opening and closing of the lead assembly, the brush inspection tube 5 is connected to the brush inspection cavity 12, and the cell brush assembly 3 passes through the brush inspection tube 5 and extends into the brush inspection cavity 12.

[0025] Furthermore, the cell brush assembly 3 includes a guide rope 31, a control bracelet 32 ​​and a bristle portion 33. One end of the guide rope 31 passes through the brush inspection tube 5 and extends into the brush inspection cavity 12, and the other end is located outside the brush inspection tube 5. The control bracelet 32 ​​is welded and fixed to the end of the guide rope 31 extending outside the brush inspection tube 5, and is used to control the sliding of the guide rope 31 along the length direction of the brush inspection cavity 12. The bristle portion 33 is installed at one end of the guide rope 31 extending into the biopsy cavity 11 and extends out or extends into the brush inspection cavity 12 as the guide rope 31 slides. In a feasible embodiment, the bristle portion 33 can be a plurality of bristles bonded and fixed to the guide rope 31, or a bristle cover fixed on the guide rope 31. In this embodiment, the bristle portion 33 is preferably a thickened and denser bristle cover.

[0026] During actual clinical operation, if brushing inspection is required, the medical staff controls the clamp head assembly 21 to a closed state through the slip ring 24, and then pulls the guide rope 31 by hooking the control bracelet 32 ​​with the finger to extend or pull the bristle portion 33 into the brushing inspection cavity 12, so as to achieve scraping and collection of exfoliated cells in the human body; if biopsy is required, the medical staff pulls the bristle portion 33 into the brushing inspection cavity 12, and then controls the opening and closing of the clamp head assembly 21 through the slip ring 24 to concentrate on lesion biopsy.
