Background technique

With the continuous development of the medical level, preoperative biopsy has been used more and more in daily medical care in recent years. This method refers to the biopsy done before therapeutic surgery or other treatments (such as radiotherapy and chemotherapy). , generally a small part of diseased tissue is taken through a sampling device and sent for pathological biopsy, and a medical report is obtained after detection by an instrument, so as to facilitate clinical treatment.

For biopsy sampling of different parts of the human body, specific sampling devices will be used for sampling. For example, for biopsy sampling of tumor tissue in gastroenterology, the general biopsy sampling device for tumor tissue in gastroenterology performs sampling through needle aspiration and puncture. However, this sampling method uses the principle of negative pressure suction of the syringe for sampling, and the living tissue has toughness, so it is difficult for this sampling device to suck out the tissue, which will affect the sampling progress.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Referring to Fig. 1-Fig. 5, the present embodiment discloses a tissue biopsy sampling device, comprising a sampling cylinder 1, a slider 2 is slidably arranged inside the sampling cylinder 1, and a sampling rod 3 is hinged inside the slider 2. 2 is set in the middle of the sampling rod 3, not only can the up and down movement of the sampling rod 3 be more convenient, but also can increase the pressure between the barb 6 and the tumor tissue during sampling by using the principle of leverage, because the general hooking device is Directly by operating the sampling rod 3 and using the barb 6 to hook the tissue, so the force from the top to the bottom of the sampling rod 3 is larger, and the pressure on the tissue is reduced, so it is not convenient for sampling work, and in the middle part of the sampling rod 3 After the sliding block 2 is articulated, the torque will be increased to facilitate the hooking of tumor tissue. The top of the sampling rod 3 is provided with an operating handle 4, which can facilitate the operation of the sampling rod 3. The surface of the sampling rod 3 is provided with a sampling port. 5. The bottom of the sampling rod 3 is provided with a barb 6 , and the opening of the barb 6 needs to be aligned with the direction of the sampling port 5 during tissue sampling.

Preferably, the surface of the sampling cylinder 1 is slidably provided with a fixed cylinder 8, and the bottom end of the fixed cylinder 8 is provided with a fixed ring 9, and the fixed ring 9 is used to be attached to the superficial skin, so that it can be seen that the sampling cylinder 1 enters the fixed cylinder 8. The depth inside the skin.

Preferably, the inside of the fixed cylinder 8 is provided with a first limit block 11, and the surface of the sampling cylinder 1 is provided with a second limit block 10, and the first limit block 11 and the second limit block 10 are engaged with each other. When the limit block 11 is not engaged with the second limit block 10, the sampling cylinder 1 can slide up and down inside the fixed cylinder 8. When the first limit block 11 and the second limit block 10 are engaged with each other, the sampling The cylinder 1 cannot slide up and down inside the fixed cylinder 8, so that the depth at which the sampling cylinder 1 protrudes into the tumor tissue can be fixed.

Preferably, a scale 13 is provided on the surface of the sampling cylinder 1, and the depth of the sampling cylinder 1 protruding into the tumor tissue can be clearly understood by comparing the scale 13 during tissue sampling, so as to prevent the sampling cylinder 1 from passing through the tumor tissue and affecting normal tissues , to ensure the safety of tumor tissue sampling.
