Problems solved by technology

[0002] Puncture biopsy is the main method for obtaining histopathological diagnosis of bone and soft tissue tumors. At present, most of the common needle biopsy sampling devices rely on a sampling device with a hook on the top. In the actual operation process, the sampling device often takes out a local The small number of samples directly leads to deviations in diagnostic information, and it is also impossible to understand the tissue distribution in the tumor

Embodiment 1

[0016] see Figure 1-4 , the present embodiment includes a sampling tube 1, the bottom of the sampling tube 1 is provided with a puncture cone 2, and the upper top of the sampling tube 1 is provided with an end cap 3 screwed and matched with it, and the sampling tube 1 is as a whole Hollow tubular structure, one side of the sampling tube 1 is axially penetrated with a sampling groove 4 that doubles as a guide chute, the inside of the sampling tube 1 is provided with a piston head 5, and a piston head 5 is provided above the piston head 5. The piston rod 6 is screwed and fixedly connected with it. A layer of rubber layer 7 that can be in sealing contact with the inner wall of the sampling tube 1 is fixed under and around the piston head 5. The piston rod 6 is a hollow tubular structure as a whole. The piston rod 6 is provided with a driving shaft 8 that can be slidably matched with the gap, the lower end of the driving shaft 8 passes through the piston head 5 and the rubber lay...

Embodiment 2

[0022] 1. First, the medical staff hold the upper end of the sampling tube 1 with one hand, and then slowly penetrate the puncture cone 2 of the sampling tube 1 into the tumor;

[0023] 2. After piercing, the wound of the tumor will be tightly attached to the sampling groove 4;

[0024] 3. Then the medical staff pinches the piston handle 63 with the other hand, and twitches the entire piston rod 6 to move upward;

[0025] 4. The upward movement of the piston rod 6 will inevitably lead to a vacuum in the sampling tube 1, so that the wound of the tumor enters the sampling tube 1 through the sampling groove 4, and the piston head 5 passes through the scraper blade 11 in the process of rising. cutting off the part of the tumor entering the sampling tube 1;

[0026] 5. The sliced ​​part of the tumor enters the guide groove 12 in a strip shape, and the rising piston rod 6 drives the driving shaft 8 to rotate through the positioning shaft 81 and the spiral chute 62 at the same time....

Abstract

The invention discloses a gastrointestinal tumor biopsy sampling device, including a sampling pipe (1). The bottom of the sampling pipe (1) is provided with a puncturing cone (2), the upper top of thesampling pipe (1) is provided with an end cover (3) matched with the sampling pipe in a rotary mode, the sampling pipe (1) is of a hollow pipe-shaped structure integrally, one side of the sampling pipe (1) is axially provided in a penetrating mode with a sampling groove (4) which concurrently is a guide sliding groove, the sampling pipe (1) is internally provided with a piston top (5), and the upper part of the piston top (5) is provided with a piston rod (6) fixedly and rotatably connected with the piston top. According to the gastrointestinal tumor biopsy sampling device, the structure is simple, an integral sampling from bottom to top in entire tumour can be achieved, and growth and tissue distribution conditions of the tumour are convenient to understand by medical workers.

Description

technical field [0001] The invention relates to the technical field related to medical treatment, in particular to a biopsy sampler for digestive tract tumors. Background technique [0002] Puncture biopsy is the main method for obtaining histopathological diagnosis of bone and soft tissue tumors. At present, most of the common needle biopsy sampling devices rely on a sampling device with a hook on the top. In the actual operation process, the sampling device often takes out a local The small number of samples directly leads to deviations in diagnostic information, and it is also impossible to understand the tissue distribution within the tumor. Contents of the invention [0003] The purpose of the present invention is to provide a digestive tract tumor biopsy sampler, which can effectively solve the problems in the background technology. [0004] In order to solve the existing problems in the background technology, it includes a sampling tube 1, the bottom of the samplin...
