Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically refers to a prostate puncture surgical device. Background Art

[0002] Prostate puncture surgery, medically known as prostate biopsy, is a medical procedure used to diagnose prostate cancer. When the prostate-specific antigen level is elevated or an abnormality is detected during a digital rectal examination by a doctor, this examination may be performed for further diagnosis. The tissue samples obtained will be sent to a laboratory, where a pathologist will examine under a microscope for the presence of cancer cells. Based on the examination results, the doctor will decide whether further treatment or monitoring is required. Prostate biopsy is the gold standard for diagnosing prostate cancer and is crucial for the early detection and treatment of prostate cancer, enabling effective and timely understanding of the prostate's health status.

[0003] Puncture surgery usually involves transrectal biopsy and perineal biopsy. Compared with transrectal puncture, perineal puncture has almost no risk of infection, and the detection blind area is smaller than that of transrectal puncture. During perineal biopsy, the patient needs to lie flat on the bed. After local disinfection and anesthesia, an ultrasonic probe is inserted through the anus and pressed upward against the prostate in the rectum. Subsequently, a puncture needle is inserted through the perineum (between the male private part and the anus) for sampling. Currently, in perineal prostate puncture surgery, only medical non-woven fabric is usually used to cover the surrounding area. In case of surgical operation errors, it may harm other tissues of the patient. The traditional method cannot effectively protect the patient. At the same time, the puncture surgery has high technical requirements for medical staff, and the traditional method cannot provide operation assistance for medical staff. Summary of the Invention

[0004] In view of the above situation, to overcome the defects of the prior art, the present invention provides a prostate puncture surgical device that can effectively protect the patient during the puncture surgery and can assist medical staff in performing the surgery, reducing the surgical difficulty.

[0020] The beneficial effects achieved by the present invention with the above structure are as follows: A prostate puncture surgical device provided by this solution, when in use, rotate the positioning bin to make the opening and closing angle of the protection plate fit the patient's leg. Then bend the leg protection mechanism towards the patient's leg, so that the protection plate can fit the inner thigh curve of the patient to cover and protect the patient's leg. The hinge members arranged in a hinged manner can adapt to patients of different body types to achieve different degrees of bending. The arc-shaped plate arranged above can also block the private parts of male patients to prevent accidental slipping during the operation, which may affect the progress of the operation. At the same time, rotate the operation handle. After being transmitted through the roller, the third bevel gear, the second bevel gear, the universal joint, the second bevel gear, and the first bevel gear, control the driving wheel arranged below to rotate. The driving wheel drives the transmission belt to move, synchronously driving the connecting blocks on both sides to move, thereby adjusting the height of the puncture assisting mechanism. Pass the puncture needle through the positioning cylinder, and the positioning cylinder can assist medical staff to fix the puncture needle, thereby reducing the operation difficulty of the puncture operation. Compared with the traditional method, this method can effectively protect the patient during the puncture operation, and at the same time can assist medical staff in the operation, reduce the operation difficulty, and can be flexibly adjusted to adapt to patients of different body types.
