Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a connecting joint for an endoscope handle. Background Art

[0002] Hysteroscopy is a new, minimally invasive gynecological diagnosis and treatment technology. It is a fiber light source endoscope used for uterine cavity inspection and treatment. Two connecting joints for the endoscope handle need to be set on the hysteroscope handle, one joint as the water inlet and the other as the water outlet. During the use of the hysteroscope, physiological saline needs to be injected from the water inlet to clean the uterine cavity. After cleaning, the water in the uterine cavity must also be discharged from the water outlet to facilitate the detection of inflammation in the uterine cavity. At present, the connection between the connecting joint for the endoscope handle and the hysteroscope handle is connected by gluing. This connection method is prone to degumming after a long period of use, resulting in axial displacement of the connecting joint for the endoscope handle during work, affecting the work of medical staff.

In this case, the connecting tube 1 is limited in the radial direction through the connecting hole 6, and the limiting block 8 is inserted into the limiting frame 7, so that the connecting tube 1 can be limited in the circumferential direction. The first limiting plate 3 and the second limiting plate 4 are used to limit the connecting tube 1 axially, ensuring that the connecting joint used for the endoscope handle will not be displaced during work, and the connecting tube 1 can be fixed without glue or other adhesives.

[0022] Further, the hysteroscope handle 5 is a hollow structure composed of an upper handle 51 and a lower handle 52. A semicircular clamping groove 53 is provided in the middle of the lower surface of the end of the upper handle 51 and in the middle of the upper surface of the end of the lower handle 52. The two clamping grooves 53 are butted and combined to form the connection hole 6. A "C"-shaped limiting frame 7 is connected to the rear end wall at the clamping groove 53 of the lower handle 52. When the inner wall of the first limiting plate 3 contacts the end wall of the hysteroscope handle 5, the outer wall of the second limiting plate 4 contacts the outer wall of the limiting frame 7. During installation, the connecting pipe 1 is placed on the connection hole 6, the limiting block 8 is engaged with the limiting frame 7, and then the upper handle 51 and the lower handle 52 are connected, and the installation of the connection joint for the endoscope handle can be completed.
