Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a conveniently adjustable pathological sampling device. Background Art

[0002] A nasopharyngeal biopsy is a method of obtaining a sample of nasopharyngeal tissue for pathological examination. This biopsy can be used to diagnose and evaluate nasopharyngeal diseases, including nasopharyngeal carcinoma and other nasopharyngeal lesions. This procedure is usually performed in an operating room and requires the use of a mirror or other tool to introduce a sampling device into the nasopharynx. The tissue sample is then collected using a nasopharyngeal endoscope and biopsy forceps. The sampling process may cause some discomfort or slight pain. The nasopharyngeal tissue sample obtained will be sent to the laboratory for pathological examination.

[0003] Traditional nasopharyngeal endoscopes and biopsy forceps usually use a snake tube for bending, observation and sampling when taking tissue samples. However, since the snake tube usually has a large bending radius when bending, and the space in the nasopharynx is small, when the snake tube drives the nasopharyngeal endoscope and biopsy forceps to bend, observe and sample, not only is the bending space limited, but the field of view may be limited by the size and shape of the instrument, providing a limited field of view, and some smaller or hidden lesions may not be easy to detect. At the same time, due to the large bending radius of the snake tube, there is also a risk of damaging tissue during insertion and operation, which may cause some patients to feel uncomfortable during the examination and even pose a safety hazard.

[0022] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0023] When in use, take the handle 1, insert the snake bone tube 2 and the rubber sleeve 3 into the patient's nasopharynx to drive the rotating head 46 to move into the patient's nasopharynx, use the LED light source 6 to illuminate the patient's nasopharynx, and use the camera 5 to observe. As the movement progresses, if the observation angle of the camera 5 needs to be adjusted, the gear 44 can be rotated by turning the rotating rod 43. The rotation of the gear 44 can cause the track 42 to move. When the track 42 moves, the length of the track 42 on both sides of the gear 44 can be changed, that is, one end becomes shorter and the other end becomes longer. The shortened end can pull the rotating head 46 to rotate, and the longer end can provide a rotating space for the rotating head 46 to rotate, thereby changing the illumination angle of the camera 5, which is convenient for nasopharyngeal observation. When the snake bone tube 2 drives the rotating head 46 to move to a suitable position, it is necessary to assemble When taking tissue samples, push the spring tube 8 forward. The forward movement of the spring tube 8 can push the biopsy forceps 7 forward until the biopsy forceps 7 moves out of the inner cavity of the storage slot 47 and moves out a suitable length. Use the biopsy forceps 7 to take tissue samples. After the sampling is completed, pull the spring tube 8 backward to pull the biopsy forceps 7 into the inner cavity of the storage slot 47 until the biopsy forceps 7 moves to the initial position. Pull the snake bone tube 2 backward until it moves out of the patient's nasopharynx to complete the tissue sampling. The device can adapt to the needs of the narrow space of the nasopharynx, avoids the problems of limited field of view and patient discomfort caused by the large bending radius of the traditional snake bone tube 2, improves the flexibility and operability of the instrument, and makes observation sampling more accurate and convenient. Secondly, the device effectively reduces the risk of tissue damage and reduces the discomfort of patients during the examination, thereby improving the accuracy, comprehensiveness and safety of the diagnosis.
