Description

Technical Field

[0001] The utility model belongs to the technical field of endoscopes and relates to an endoscope operating handle. Background Art

[0002] As one of the important medical devices in modern surgical operations, an endoscope includes an operating handle and an insertion part. The insertion part can enter the human body through a body cavity or a surgical incision, and with the camera module at the distal end of the insertion part, it helps doctors judge the lesion position in the patient's body and the tissue structure characteristics of the lesion position.

[0003] For example, a utility model patent with the application number CN201720593940.5 provides an endoscope handwheel mechanism, which includes a left - right control handwheel and an up - down control handwheel coaxially installed. The left - right control handwheel is located above the up - down control handwheel. A plurality of first flanges extending radially are arranged on the periphery of the left - right control handwheel, and a plurality of second flanges extending radially are arranged on the periphery of the up - down control handwheel. The outer end of each of the first flanges extends radially outward to form an extension section, and the bottom of each extension section extends downward to form a boss, and the boss is located outside the circumference where the outer end of the second flange is located.

[0004] In summary, some existing technical solutions are controlled by rotating a handwheel, but this requires the operator to hold the handle with one hand and rotate the handwheel with the other hand to adjust the endoscope. Therefore, a structure that can adjust the endoscope while holding the handle with one hand is needed, and there is a large room for improvement. Summary of the Invention

[0005] The purpose of the utility model is to provide an endoscope operating handle for the above - mentioned problems existing in the prior art.

[0006] The purpose of the utility model can be achieved by the following technical solutions: An endoscope operating handle includes:

[0007] A handle body for inserting into a steering tube;

[0008] Two traction ropes are arranged inside the handle body.

[0009] A rotating assembly includes a push rod and a rotating disk. The push rod is rotatably connected to the handle body, the rotating disk is connected to the push rod, and both traction ropes are connected to the rotating disk. When the push rod rotates in one direction, it drives the rotating disk to rotate in the same direction and pulls one of the traction ropes.

[0010] In the above-described endoscopic operation handle, the rotating assembly further includes a locking seat. The push rod is provided with a locking position and an unlocking position. The locking seat is movably connected to the push rod and can move to the locking position or the unlocking position. When the locking seat moves to the locking position, it contacts the handle body, and when the locking seat moves to the unlocking position, it separates from the handle body.

[0011] In the above-described endoscopic operation handle, the locking seat is provided with a contact block. The contact block is detachably connected to the locking seat, and the locking seat can contact the handle body through the contact block.

[0012] In the above-described endoscopic operation handle, the contact block is an elastic member.

[0013] In the above-described endoscopic operation handle, the push rod includes two half rods. The two half rods are detachably connected, and when the two half rods are connected, they are joined together to form the push rod.

[0014] In the above-described endoscopic operation handle, the half rod is provided with a half chute. When the two half rods are connected, the half chutes of the two half rods are joined together to form a sliding track, and the locking seat is movably connected to the sliding track.

[0015] In the above-described endoscopic operation handle, the handle body includes two handle pieces. The two handle pieces are detachably connected, and when the two handle pieces are connected, they are joined together to form the handle body.

[0016] In the above-described endoscopic operation handle, it further includes a clamping seat. The clamping seat is connected to the rotating disk. The clamping seat is provided with a clamping groove, and the traction rope is embedded in the clamping groove so that the traction rope is detachably connected to the clamping seat.

[0017] In the above-described endoscopic operation handle, it further includes a fixing block. The fixing block is detachably connected to the clamping seat, and the fixing seat restricts the traction rope in the clamping groove.

[0018] In the above-described endoscopic operation handle, it further includes a protective sleeve. The protective sleeve is detachably connected to the handle body, and the protective sleeve is used to cover the part of the steering tube exposed from the handle body.

[0019] Compared with the prior art, the beneficial effects of the present utility model are:

[0020] 1. A rotating disk for fixing a towing rope is provided on the handle body. When the push rod rotates in one direction, it drives the rotating disk to rotate in the same direction and pulls one of the towing ropes, thereby driving the steering tube to bend in a specific direction, facilitating the user to adjust the endoscope while holding the handle with one hand.

[0021] 2. When the locking seat moves to the locking position, it contacts the handle body, or when it moves to the unlocking position, it separates from the handle body. The locking can be achieved by moving the locking seat from the unlocking position to the locking position when the push rod drives the rotating disk to rotate to a specified position.

[0022] 3. The towing rope is embedded in the clamping groove, so that the towing rope is detachably connected to the clamping seat. Therefore, while ensuring the connection between the towing rope and the rotating disk, the two can also be relatively disassembled; the fixing seat restricts the towing rope in the clamping groove, so that the towing rope is not easily separated from the clamping groove.

[0023] 4. The contact block is set as an elastic member. Therefore, when the locking seat contacts the handle body through the contact block, the contact block can deform and increase the friction between the two, enhancing the locking ability.

[0024] 5. The locking seat can contact the handle body through the contact block, so that the locking seat does not need to directly contact the handle body and cause wear. By replacing the contact block, the locking effect brought by the contact friction between the contact block and the handle body can always be ensured. Description of the Drawings

[0050] As Figures 1-4 shown, on the basis of the above-described embodiment, the half rod 311 is provided with a half chute 312. When the two half rods 311 are connected, the half chutes 312 of the two half rods 311 are joined together to form a sliding track, and the locking seat 330 is movably connected to the sliding track.

[0051] In this embodiment, the locking seat 330 is movably connected to the sliding track so that the locking seat 330 is movably connected to the push rod 310, and the locking seat 330 can be moved to the locking position or the unlocking position.

[0052] As Figures 1-4 shown, on the basis of the above-described embodiment, the handle body 100 includes two handle pieces 110, and the two handle pieces 110 are detachably connected. When the two handle pieces 110 are connected, they are joined together to form the handle body 100.

[0053] As Figures 1-4 shown, on the basis of the above-described embodiment, a clamping seat 400 is further included. The clamping seat 400 is connected to the rotating disk 320. The clamping seat 400 is provided with a clamping groove 410, and the traction rope 200 is embedded in the clamping groove 410 so that the traction rope 200 is detachably connected to the clamping seat 400.

[0054] In this embodiment, the traction rope 200 is embedded in the clamping groove 410 so that the traction rope 200 is detachably connected to the clamping seat 400. Therefore, while ensuring the connection between the traction rope 200 and the rotating disk 320, the two can also be relatively disassembled.

[0055] As Figures 1-4As shown, on the basis of the above-described embodiment, a fixing block 500 is further included. The fixing block 500 is detachably connected to the clamping seat 400, and the fixing seat restricts the towing rope 200 within the clamping groove 410.

[0056] In this embodiment, the fixing seat restricts the towing rope 200 within the clamping groove 410, so that the towing rope 200 is not easily separated from the clamping groove 410.
