[0035] See also Figures 1 to 4 The utility model discloses an endoscope handle, including a housing 100, a key pressing ring 200, a key cap 300 and an opening retaining ring 400.

[0036] It should be understood that the endoscope includes a control panel arranged in the shell 100, on which are arranged a button module, a knob module and an external module. The button module and the knob module are used to transmit control signals to the control panel, and the external module is used for communication between the control panel and external devices, such as a display and a power supply.

[0037] The shell 100 includes a connected ball head 110 and a gripping portion 120. Both the ball head 110 and the gripping portion 120 are provided with an inner cavity, and the inner cavity of the ball head 110 and the inner cavity of the gripping portion 120 are connected. The ball head 110 is used to install and connect auxiliary equipment, and the gripping portion 120 is for the operator to hold.

[0038] The ball head 110 is provided with a plurality of limiting grooves 111, and the bottom of the limiting grooves 111 is provided with a button hole 112 connected to the inner cavity of the ball head 110, and the limiting grooves 111 are coaxial with the button hole 112;

[0039] One end of the key ring 200 is provided with an annular clamping groove 210, and the other end of the key ring 200 is provided with an annular convex stopper 220, and the outer diameter of the convex stopper 220 is larger than the inner diameter of the limiting groove 111;

[0040] The key cap 300 is elastic and is sleeved on the other end of the key pressing ring 200 and the convex stop 220;

[0041] The open retaining ring 400 is stuck in the limiting groove 111 and abuts against the inner wall of the ball head 110. The groove wall of the limiting groove 111 and the key pressing ring 200 clamp the key cap 300 to deform the key cap 300 and form a seal between the groove wall of the limiting groove 111 and the key pressing ring 200.

[0042] The open retaining ring 400 is stuck in the limiting groove 111. When the open retaining ring 400 abuts against the inner wall of the ball head 110, the key pressing ring 200 can be prevented from exiting the key hole 112. The outer diameter of the convex stopper 220 is larger than the inner diameter of the limiting groove 111, and the convex stopper 220 cannot pass through the key hole 112, thereby limiting the key pressing ring 200 in the key hole 112. The inner diameter of the key hole 112 matches the outer diameter of the key pressing ring 200, and the inner wall of the key hole 112 plays a role in guiding the key pressing ring 200 to move.

[0043] When installing the key pressing ring 200, the key cap 300 and the open retaining ring 400, first put the key cap 300 on one end of the key pressing ring 200 and the convex retainer 220, and then push the key cap 300 and the key pressing ring 200 into the key hole 112. At this time, the key cap 300 undergoes elastic deformation, and a seal is formed between the groove wall of the limiting groove 111 and the key pressing ring 200 until one end of the key pressing ring 200 extends into the inner cavity of the ball head 110, and then the open retaining ring 400 is clamped in the limiting groove 111. Finally, the open retaining ring 400 is against the inner wall of the ball head 110 to prevent the key pressing ring 200 from withdrawing from the key hole 112.

[0044] One end of the key pressing ring 200 is used to press the key module. When the key cap 300 is pressed into the ball head 110, the key cap 300 pushes the key pressing ring 200 into the ball head 110, and the key pressing ring 200 presses or contacts the key module.

[0045] See also Figure 4 In some of the embodiments, the outer circumferential surface of the key cap 300 is provided with an annular protrusion 310, and the protrusion 310 is interference fit with the limiting groove 111. The protrusion 310 and the inner circumferential wall of the limiting groove 111 form a seal to further improve the sealing and waterproof properties.

[0046] See also Figure 4 In some of the embodiments, a receiving groove 320 is provided on one end surface of the key cap 300, and the groove cavity of the receiving groove 320 includes a receiving portion and a notch portion, the inner diameter of the receiving portion is larger than the inner diameter of the notch portion, and the receiving portion cooperates with the convex stop 220 so that the key cap 300 is covered on the convex stop 220, and the key cap 300 is connected to the convex stop 220.

[0047] The inner diameter of the storage portion is larger than the inner diameter of the slot portion, so that one end face of the key cap 300 is located between the inner groove bottom of the limiting groove 111 and the side of the protrusion 220, that is, part of the structure of the key cap 300 is located between the inner groove bottom of the limiting groove 111 and the side wall of the slot portion, and part of the structure of the key cap 300 can undergo elastic deformation.

[0048] In some embodiments, the height of the receiving portion is greater than the height of the convex stop 220, so that the key cap 300 can move away from and close to the key pressing ring 200, that is, the key cap 300 can move relative to the key pressing ring 200. When the key pressing ring 200 is pressed down by the key cap 300, the key cap 300 is concave, and then the key cap 300 returns to the pop-up state.

[0049] See also Figure 4In some embodiments, a guide column 330 is provided at the bottom of the inner groove of the storage groove 320. The guide column 330 is passed through the center hole 230 of the key pressure ring 200. When the key cap 300 is pressed, the guide column 330 is inserted into the center hole 230. When the key cap 300 returns to the pop-up state, the guide column 330 moves in the direction of exiting the center hole 230. The cooperation between the guide column 330 and the center hole 230 can prevent the deformation direction of the key cap 300 from being offset.

[0050] It can be understood that the center hole 230 is disposed at the central axis of the guide column 330 , and the center hole 230 is chamfered at one end corresponding to the key press ring 200 .

[0051] See also Figure 4 In some embodiments, an annular protrusion 113 is provided at the inner bottom of the limiting groove 111 , and the end surface of the key cap 300 abuts against the protrusion 113 , so that a seal is formed between the end surface of the key cap 300 and the inner bottom of the limiting groove 111 .

[0052] See also Figure 1 and Figure 5 In some embodiments, the endoscope handle further includes a ventilation component 500, a ventilation hole is provided on the ball head 110, the ventilation component 500 is disposed in the shell 100, one end of the ventilation component 500 is sealedly connected to the inner wall of the ventilation hole, and the ventilation component 500 can transmit gas and liquid between the human body and the outside world.

[0053] Gas and liquid are likely to remain in the vent assembly 500 , making it inconvenient to thoroughly clean the interior of the vent assembly 500 .

[0054] In some embodiments, the vent assembly 500 includes a suction button seat 510, a pipe 520 and a tee 530 connected in sequence, and a transfer tube 600 is provided on the housing 100, and one end of the transfer tube 600 is connected to one of the other two ports of the tee 530. The transfer tube 600 is used for draining liquid, and is provided at one end of the grip 120 away from the ball head 110.

[0055] Since the inner cavity of the housing 100 is irregular in shape, in order to adapt to the inner cavity of the housing 100 , the pipe 520 is curved, and the inner wall of the pipe 520 has a smooth transition.

[0056] The pipeline 520 is an integral structure, and the pipeline 520 is formed in one piece. Compared with the combined pipeline 520, or compared with the split pipeline 520, the integral pipeline 520 has fewer connection seams, which is beneficial to reduce residual bacteria, etc., and has a better cleaning and disinfection effect, reducing the risk of cross infection.

[0057] See also Figure 1In some embodiments, the endoscope handle also includes an aviation plug 700, a wiring hole is provided on the ball head 110, the aviation plug 700 is threadedly connected to the wiring hole, and a glue layer is provided between the aviation plug 700 and the wiring hole, so that a seal is formed between the aviation plug 700 and the side wall of the wiring hole.

[0058] In some embodiments, a leak detection valve and a knob are provided on the ball head 110. The leak detection valve is a one-way valve that can deliver air into the housing 100. The output end of the knob is connected to the knob module.

[0059] The key cap 300 is made of a silicone material, and the pipe 520 is made of a stainless steel material.
