Problems solved by technology

At present, the existing sampling devices generally open a sampling gap at the front end of the puncture needle, insert the puncture needle into the tumor, and cut the tumor entering the gap to realize sampling; however, during use, due to the expansion effect of the outer wall of the puncture needle , the amount of tumor entering the gap cannot be guaranteed, and the situation of sampling less or empty sampling often occurs, requiring medical staff to sample the patient's tumor many times, causing additional damage to the patient

Embodiment 1

[0023] like figure 1 , 7 As shown, a sampling device for medical oncology treatment includes a puncture needle tube 1, two semiconical tubes 2, and a sampling assembly; the two semiconical tubes 2 are symmetrically arranged at one end of the puncture needle tube 1, and the two semiconical tubes 2 The bottom of the puncture needle tube 1 is hinged with the puncture needle tube 1 to form a conical sampling groove; the sampling assembly is arranged on the puncture needle tube 1, and is used to extend into the tumor through the conical sampling groove for sampling; the sampling assembly includes two sets of V-shaped arc blades 3 are respectively arranged on the inner edges of the two semi-conical tubes 2, the V-shaped arc-shaped blade 3 is connected with the semi-conical tube 2, and the proximal end of the V-shaped arc-shaped blade 3 is inclined downward; 4. The inner edges of two semi-conical tubes 2 are respectively arranged on the inner edges and are centrally symmetrical with...

Embodiment 2

[0026] In order to further improve the convenience of operation, the operator can precisely control the penetration depth of the syringe through the drive mechanism, which is convenient for sampling tumors in different positions and improves the accuracy of tumor biopsy; the rotating shaft of the transmission mechanism and the first U-shaped connecting seat The connecting plate can realize the opening and closing action of two semi-conical tubes, and then cooperate with the elastic hinge arm and the connecting tube to realize flexible control of the opening and closing of the conical sampling groove.

[0027] like image 3 As shown, preferably, the drive mechanism includes a syringe 21 disposed at the other end of the puncture needle tube 1 and coaxial with it, the input end of the syringe 21 is fixedly connected to the puncture needle tube 1, the piston of the syringe 21 is connected to the inner tube 5, and the inner tube 5. The side away from the syringe 21 is provided with...

Embodiment 3

[0031] In order to further improve the operation safety, the conical sampling groove can be stored when not in use or after tumor cutting and sampling is completed through the rotating and fitting connection between the external thread tube and the puncture needle tube, not only the semi-conical tube and the V-shaped arc knife can be stored. The protection can not be used to avoid fall injury, and it can prevent the tumor-contaminated semi-conical tube from contacting normal tissue and causing tumor cells to spread.

[0032] Preferably, the side of the puncture needle tube 1 close to the half-conical tube 2 is provided with an inner thread 51 , the end of the connecting tube 34 away from the half-conical tube 2 is sleeved with an externally threaded tube 52 , and the half-conical tube 2 is fixedly connected with the connecting tube 34 . , the external thread tube 52 is matched and connected with the internal thread 51 , and the connecting tube 34 is slidably connected with the ...

Abstract

The invention relates to a sampling device for medical oncology treatment, and belongs to the technical field of medical equipment for medical oncology, the sampling device comprises a puncture needle tube, two semi-conical tubes are symmetrically arranged at one end of the puncture needle tube, and a sampling assembly is arranged on the puncture needle tube and used for stretching into a tumor through a conical sampling groove for sampling; the sampling assembly comprises two groups of V-shaped arc-shaped cutting edges which are respectively arranged on the inner side edges of the two semi-conical tubes, two groups of V-shaped sinking grooves are respectively arranged on the inner side edges of the two semi-conical tubes, and the V-shaped arc-shaped cutting edges are embedded into the V-shaped sinking grooves and are connected with the V-shaped sinking grooves in a matched manner to form a V-shaped shearing surface; the two semi-cones are matched with the puncture needle tube to form the puncture needle which can be punctured into the human body, the puncture needle is matched with the V-shaped arc-shaped blade and the V-shaped sinking groove of the sampling assembly to cut a tumor, and then the puncture needle is taken out of the human body through the conical sampling groove formed by the two semi-cones; the sampling device is convenient to use, high in sampling stability, high in practicability and worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of medical oncology medical equipment, and in particular relates to a sampling device for medical oncology treatment. Background technique [0002] Tumors refer to new organisms formed by the proliferation of local tissue cells under the action of various carcinogenic factors, because these new organisms are mostly space-occupying massive protrusions, also known as neoplasms. Studies have found that tumor cells have metabolic changes different from those of normal cells, and tumor cells themselves can adapt to changes in the metabolic environment through the conversion between glycolysis and oxidative phosphorylation. Tumor is a disease that seriously endangers human health and life. In recent years, the incidence rate has gradually increased, and the age of onset has gradually decreased. Early detection, correct diagnosis, and timely treatment have an important impact on prognosis. With the continuous impr...
