Description

Integrated arthroscope for puncture detection

Technical Field

The utility model relates to an arthroscope, in particular to an arthroscope integrating puncture detection.

Background

And the arthroscope is used for detecting the lesions or injuries of the joint tissues of the human body. The existing arthroscope needs to make an incision on the skin when performing detection, then the arthroscope is placed into a joint through the incision, and a camera and display device is connected behind the arthroscope to observe the intra-joint morphology and lesions. Because the incision making device and the arthroscope are independent devices, the arthroscope cannot be inserted at the same time when the incision is made, wherein the incision is made by using a puncture needle or other surgical instruments, and the corresponding devices are taken out and then put into the arthroscope for detection after the incision is made, the operation process is increased, and the patient is injured for many times when the incision is made and the arthroscope is inserted through the incision, so that the pain of the patient is increased.

Chinese patent CN106419822B discloses an integrated arthroscope, which has an integrated structure that a sheath tube is used as a carrier, and then a puncture needle and an arthroscope body are sequentially assembled and disassembled in the sheath tube to realize puncture and detection and injection of medicament. When the puncture needle is used, the puncture needle is sleeved into the sheath tube of the endoscope, the tip is exposed, and the puncture needle handle is locked by the second locking device. Unlocking the second locking device after the puncture is completed, taking out the puncture needle, sleeving the arthroscope device into the endoscope sheath, exposing the miniature camera head at the front end of the insertion part, locking by the second locking device, and connecting with the injection syringe. Although the arthroscope of the patent can puncture, detect and inject, the puncture needle, the arthroscope body and the arthroscope sheath are three independent components and cannot be applied simultaneously, and the puncture needle is still required to be matched with the arthroscope sheath to puncture and then pull out the puncture needle, and then the cavity of the arthroscope sheath is used for inserting the arthroscope body, so that the arthroscope is complex in structure and unfavorable for use.
