Description

A tumor sampler for breast surgery

technical field

The utility model relates to the technical field of medical equipment, in particular to a tumor sampler for breast surgery.

Background technique

Breast tumor masses are most common in the outer upper quadrant, followed by the nipple, areola area, and inner upper quadrant. Because most of them have no subjective symptoms, the lumps are often found by patients inadvertently (such as bathing and changing clothes). A small number of patients may have tenderness or irritation and nipple discharge in various degrees. The growth rate of the malignant tumor mass is relatively fast, and the invasion of the surrounding tissue can cause changes in the shape of the breast and a series of signs. Such as: the surface of the tumor is sunken; the cancer adjacent to the nipple can lead the nipple to the direction of the cancer; the nipple is fixed and so on. "Orange peel-like" changes may appear in advanced breast cancer. These are all important signs of breast cancer.

At present, it is well known that for patients with fibroids or proliferative nodules on the breast, pathological examination is required to exclude breast cancer. During the examination, a small piece of tissue must be surgically excised for examination, which not only increases the pain of the patient, but also brings pain to the patient. The workload of medical staff has increased.

At present, Chinese patent CN201814601U discloses a puncture needle for breast pathological examination, which solves the above problems, and its incision is small, which can reduce the pain of patients, reduce the workload of medical staff, and improve work efficiency. In the normal state, when the puncture needle is sent into the tumor, the tumor tissue that first touches the sampling hole will fall into the sampling hole, which is not conducive to sampling, especially not conducive to the sampling of specific parts. When it is necessary to take samples from the middle of the tumor Or when the tissue at the bottom, at this time the sampling hole needs to move in the tumor tissue, increasing the pain of the patient, which needs to be improved urgently.

In order to achieve the above object, the technical solution adopted by the utility model is: it includes a sampling rod and a puncture needle, the end of the sampling rod is provided with a puncture needle, and one side wall of the sampling rod is provided with a sampling port; the inside of the sampling rod is inserted with a A rotating rod, the outer end of the rotating rod is connected with a rotating ring, the inner end of the rotating rod is connected with a sampling end, and the sampling end is arranged in close contact with the inner wall of the sampling rod; one side of the sampling end is provided with a sampling groove, The upper and lower edges of the sampling tank are provided with sampling blades.

Further, the inner sidewall of the sampling groove is rectangular.

Further, the inner side wall of the sampling groove is arc-shaped.

Further, the outer wall of the sampling end is embedded with medical cotton.

Further, the outer diameter of the rotating rod is the same as that of the sampling end.

After adopting the above-mentioned structure, the beneficial effects of the utility model are: a tumor sampler for breast surgery described in the utility model, which can ensure a small incision and at the same time facilitate the sampling of the target part, and reduce the impact of blood on the sampling. The utility model has the advantages of simple structure, reasonable setting, low production cost and the like.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Specific implementation mode one:

Referring to Fig. 1-shown in Fig. 5, the technical scheme that this specific embodiment adopts is: it comprises sampling rod 1, puncture needle 2, the end of sampling rod 1 is provided with puncture needle 2, and one end side wall of sampling rod 1 is provided with. There is a sampling port 1-1; the inside of the sampling rod 2 is inserted with a rotating rod 4, the outer end of the rotating rod 4 is welded with a rotating ring 3, the inner end of the rotating rod 4 is connected with a sampling end 5, and the sampling end 5 is connected to the sampling port. The inner wall of the rod 1 is attached and arranged; one side of the sampling end 5 is provided with a sampling groove 5-2, and the upper and lower edges of the sampling groove 5-2 are provided with a sampling blade 5-1, and the sampling end 5 , the sampling blade 5-1, the sampling slot 5-2 and the rotating rod 4 are integrally formed by forging.

Further, the inner wall of the sampling groove 5-2 is rectangular.

Further, the inner wall of the sampling groove 5-2 is arc-shaped, which increases the volume of the sampling groove 5-2.

Further, the outer diameter of the rotating rod 4 is the same as that of the sampling end 5 .

The working principle of this specific embodiment: before sampling, rotate the rotary rod 4, fit the outer wall of the sampling tip 5 into the sampling port 1-1 on the sampling rod 1, and then send the whole body into the tumor with the puncture needle 2 In the tissue, when the part to be sampled is reached, the rotating rod 4 drives the sampling head 5 to rotate, and when the sampling groove 5-2 on the sampling head 5 corresponds to the sampling port 1-1, the tumor tissue will fall into the sampling port 1-1, rotate the rotary rod 4 again, at this time, the sampling blade 5-1 located on the sampling end 5 cuts the sample trapped in the sampling port 1-1, and the cut sample falls into the sampling groove 5-2 Inside, with the rotation of the rotating rod 4, it is sealed between the sampling end 4 and the sampling rod 1. At this time, the outer wall of the sampling end 5 fits and seals with the sampling port 1-1 again, so as to prevent tumor tissue from leaking blood into the sampling The contamination in the tank 5-2 is sampled, and the rotation of the rotary rod 4 can be continuous or discontinuous during the whole sampling process.

After adopting the above-mentioned structure, the beneficial effects of this specific embodiment are: the tumor sampler for breast surgery described in this specific embodiment can ensure that the incision is small, and at the same time, it can also facilitate the sampling of the target part, and reduce the impact of blood on the tumor sampler. Sampling pollution improves sampling accuracy, reduces pain of patients, and has stronger practicability. The utility model has the advantages of simple structure, reasonable setting, and low manufacturing cost.

Specific implementation mode two:

Referring to Fig. 6, the difference between this specific embodiment and the first specific embodiment is that: the outer wall of the sampling tip 5 is embedded with medical cotton 7, which is used for absorbing blood exuded from the tumor tissue during the sampling process. , to reduce the contamination of the sample by blood, and the rest of the components and connections are the same as those in the first embodiment.

The above is only used to illustrate the technical solution of the utility model without limitation, other modifications or equivalent replacements made by those skilled in the art to the technical solution of the utility model, as long as they do not depart from the spirit and scope of the technical solution of the utility model , should be covered in the scope of the claims of the present utility model.
