Embodiment 1

[0034] see figure 1 with figure 2 , which shows an example diagram of the structure of the endoscope handwheel locking mechanism given in this example.

[0035] As can be seen from the figure, the endoscope handwheel locking mechanism 100 is mainly composed of a locking ring 160, a limiting sleeve 110, a limiting plate 120 and a plurality of limiting blocks 130 in cooperation with each other.

[0036] Wherein, the locking ring 160 is integrally fixed and arranged in the handwheel assembly of the endoscope, so as to realize the cooperation between the locking mechanism 100 and the handwheel of the endoscope.

[0037] The limiting sleeve 110 is relatively fixedly arranged in the locking ring 160, and there is a gap between them.

[0038] The limiting plate 120 is disposed above the limiting sleeve 110 , and the limiting plate 120 can rotate relative to the limiting sleeve 110 .

[0039] Several limiting blocks 130 are integrally and movably arranged between the limiting plat...

Embodiment 2

[0086] This example provides a handwheel locking mechanism based on Example 1 to provide a highly reliable endoscope.

[0087] see Figure 8 with figure 2 , the endoscope solution given in this embodiment mainly includes a handwheel locking mechanism 100 , a handwheel assembly 200 and a spindle 300 .

[0088] The handwheel locking mechanism 100 is the endoscope handwheel locking mechanism given in Example 1, and the specific structure has been described in detail in Example 1, and will not be repeated here.

[0089] The handwheel locking mechanism 100 is placed on the top of the handwheel assembly 200 as a whole, and the installation sequence is as follows: the locking ring 160 in the handwheel locking mechanism 100 is penetrated into the main shaft 300 and fixedly connected with the handwheel assembly 200, and then the limit sleeve 110 It is fixedly connected with the main shaft 300 , and then the limiting block 130 is placed in the sliding groove 111 of the limiting sleev...

Abstract

The present invention disclosed a type of endoscopic hand wheel lock mechanism and endoscopy. The endoscope hand wheel locking mechanism locks the ring, limited set, limited board, limited block, locking ring solidly settingsIn the handwheel component of the endoscope; the limited jacket is set in the lock ring, and the gap between the lock ring is matched and the two are relatively fixed;The restrictions are rotated; the limit block can be moved between the limits and the limit board. When the restriction board rotates, the limit block is driven by the limit plate to drive the along the place where the position is driven along the placeThe limits are moved in the inner ring of the lock ring, and the lock lock ring is repaid in the lock ring and the lock ring is separated from the lock ring to unlock the lock ring.The scheme provided by the present invention can greatly improve the reliability of locking and avoid the end mirror bending part to the state before locking.

Description

technical field [0001] The invention relates to endoscope technology, in particular to the hand wheel rotation and locking technology in the endoscope. Background technique [0002] Endoscopes are widely used in the field of medical diagnosis. The endoscope includes a handwheel, a bending part controlled by the rotation of the handwheel, and a handwheel locking mechanism. During use, it is clinically necessary to lock the curved part at a specific angle for photographing, lesion treatment, etc. At this time, the operator can release the hand wheel for other operations. [0003] In the currently used handwheel locking mechanism, in the locked state, sometimes the bending part rebounds to the state before locking, that is, the locked state is unreliable. Contents of the invention [0004] Aiming at the problem of poor reliability of the existing endoscope handwheel locking mechanism, a highly reliable endoscope handwheel locking scheme is needed. [0005] For this reason...
