DETAILED DESCRIPTION

[0027] The utility model embodiment provides a hysteroscopic valve mother self-locking structure, such as Figure 1-8 As shown, it includes an eyepiece barrel 101, an eyepiece 102, a light guide cone 103, an insertion tube 106 and a surgical tube 109, the eyepiece 102 is installed at the top of the eyepiece barrel 101, the light guide cone 103 is arranged on the side of the outer end surface of the eyepiece barrel 101, the insertion tube 106 is connected with the end of the eyepiece barrel 101, the outer end surface of the eyepiece barrel 101 is sleeved with a sealable and detachable mirror body sleeve 118, one side of the outer end surface of the mirror barrel 101 is connected to the surgical tube 109, one side of the outer end surface of the mirror body sleeve 118 is connected to a water valve component 104, two water valve components 104 are fixedly provided on both sides of the outer end surface of the mirror body sleeve 118, the water valve components 104 on both sides are arranged in a staggered height and are located on both sides of the mirror body sleeve 118, a detachable valve core 112 is provided in the water valve component 104, and a handle 111 is welded to the top of the water valve component 104.

[0028] It should be further explained that the handle 111 acts as a switch, the top of the valve core 112 is pointed and has threads on the surface, which is convenient for subsequent installation and fixation. The water valve component 104 on one side is a water outlet component, and the water valve component 104 on the other side is a water inlet component.

[0029] Furthermore, a liquid flow cavity 119 opening outward is provided in the water valve member 104 , and valve core grooves 120 are connected to the end surfaces of both sides of the liquid flow cavity 119 . The opening on one side of the valve core groove 120 is larger than the opening on the other side, and the valve core 112 is installed in the valve core groove 120 .

[0030] Furthermore, a valve cap 113 is provided on one side of the outer end surface of the water valve member 104 , a valve mother 114 is installed in the valve cap 113 , and a valve mother spring 121 is installed between the valve mother 114 and the valve cap 113 .

[0031] Furthermore, a valve mother conical hole 122 opening outward is provided at the top end of the valve mother 114 , and a pull rod 123 is installed in the valve mother conical hole 122 .

[0032] It should be further explained that the valve mother tapered hole 122 is a through hole with a certain taper, and the other end is also provided with a through hole, which is provided with a thread, and the thread is used to connect with the top end of the valve core 112.

[0033] Furthermore, a connecting hole 125 is provided on one side of the inner wall of the valve mother tapered hole 122 , and the top end of the valve core 112 passes through the connecting hole 125 .

[0034] like Figure 8 As shown, three balls 117 are arranged in the pull rod 123. After the tip of the valve core 112 is inserted into the tapered hole 122 of the valve mother, it is aligned with the center of the balls 117 located on each side.

[0035] It should be noted that the diameter of the connecting hole 125 is larger than the diameter of the tip of the valve core 112 and smaller than the diameter of the ball 117 , and the maximum circle diameter formed by the gap between the three balls 117 is smaller than the diameter of the tip of the valve mother 114 .

[0036] Furthermore, a tie rod cap 115 for sealing is installed at the top end of the tie rod 123 , and a valve mother cap 124 is provided between the tie rod cap 115 and the tie rod 123 .

[0037] It should be noted that the tie rod cap 115 and the tie rod 123 are connected by glue.

[0039] It should be noted that a pipeline communicating with the lens barrel 101 and the insertion tube 106 is provided in the surgical tube 109 to facilitate insertion of surgical scissors for assisting the surgical work.

[0040] When using the solution, first install the cleaned valve core 112 and insert it into the valve core groove 120. After the entire valve body is assembled, connect the water inlet pipe through the water valve component 104 at one end and the water outlet pipe at the other end to complete the flow path installation work before the operation.

[0041] When disassembly and cleaning is required, under the action of the pull rod spring 116 and the valve mother tapered hole 122, the gap between the balls 117 is always the smallest and squeezes the front end of the valve core 112. When the valve core 112 is to be pulled out because the valve body is loose, it will be locked by the balls 117 and cannot be pulled out; when the pull rod cap 115 is pulled, the pull rod 123 drives the balls 117 to move in the direction of the larger space of the valve mother tapered hole 122, and the gap between the balls 117 increases. The locking of the valve core 112 by the balls 117 is released.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
