In one embodiment, referring to fig. 1, 4 and 7, a bending mechanism 100 comprises: wheel 110, first adjustment cord 120, second adjustment cord 130. The rotating wheel 110 is configured to be rotatably mounted in the control housing 200, and the rotating wheel 110 includes a bending surface 111 and a mounting surface 112 that are disposed opposite to each other. The bending surface 111 is provided with a bending groove 1111. The bending groove 1111 is provided along the circumferential direction of the wheel 110, and both ends of the bending groove 1111 penetrate the mounting surface 112. The first and second adjustment cords 120 and 130 are wound onto the mounting surface 112 along the bending groove 1111 from opposite sides of the wheel 110, respectively, and the first and second adjustment cords 120 and 130 are connected to the mounting surface 112.
In the bending mechanism 100, the first adjusting rope 120 and the second adjusting rope 130 are wound on the mounting surface 112 along the bending groove 1111 from opposite sides of the rotating wheel 110; the first adjusting rope 120 and the second adjusting rope 130 are respectively fixed on the mounting surface 112, so that it can be known that the bending mechanism 100 is reasonably designed according to the embodiment, the mounting mode of the adjusting ropes on the rotating wheel 110 is simplified, the first adjusting rope 120 and the second adjusting rope 130 are quickly mounted on the rotating wheel 110, the assembly efficiency of the endoscope is greatly improved, and the use of the endoscope by medical staff is facilitated. Since both ends of the bending groove 1111 penetrate the mounting surface 112, that is, both ends of the bending groove 1111 extend to the mounting surface 112 respectively, it is ensured that the first adjusting rope 120 and the second adjusting rope 130 are located in the bending groove 1111 when they transition from the bending surface 111 to the mounting surface 112, and the first adjusting rope 120 and the second adjusting rope 130 are prevented from being lifted at the junction of the bending surface 111 and the mounting surface 112 to be easily separated from the bending groove 1111, so that the first adjusting rope 120 and the second adjusting rope 130 are located in the bending groove 1111 all the time in the bending process, so that the insert part is stably and accurately bent in the human body, thereby being beneficial to improving the accuracy of the operation detection result. Meanwhile, the bending mechanism 100 of the embodiment has a simple structure and is convenient to operate, so that the use of medical staff is facilitated, the manufacturing cost of an endoscope is reduced, and a patient can bear the disposable use cost conveniently.
Optionally, the first adjustment cord 120 and the second adjustment cord 130 may be connected to the mounting surface 112 by a fixing member 150 by: directly to the mounting surface 112, e.g., by binding, by plugging, by knotting, etc.; or by additional securing features, such as bolts, screws, snaps, etc., to the mounting surface 112.
Alternatively, one end of the first adjustment rope 120 and one end of the second adjustment rope 130 may be connected together or disconnected. Wherein, the connection between the end of the first adjusting rope 120 and the end of the second adjusting rope 130 may be achieved by knotting, integrally forming, bonding, or other means. When the first adjusting rope 120 and the second adjusting rope 130 are connected together in an integral forming manner, the first adjusting rope 120 and the second adjusting rope 130 are the same wire rod, so that the endoscope is not only beneficial to rapid assembly; at the same time, the manufacturing cost of the bending mechanism 100 is also advantageously reduced.
It should be noted that referring to fig. 1 and 5, the connection of the first adjusting rope 120 and the second adjusting rope 130 to the mounting surface 112 through the fixing member 150 is understood as follows: when the fixing member 150 is one, the first adjusting rope 120 and the second adjusting rope 130 are connected to the mounting surface 112 together through the fixing member 150; when the number of the fixing pieces 150 is two, the first adjusting rope 120 and the second adjusting rope 130 are respectively connected to the mounting surface 112 through the two fixing pieces 150; of course, the number of the fixing members 150 may be plural, and when the number of the fixing members 150 is plural, the first adjusting rope 120 is fixed by a part of the fixing members 150, and the second adjusting rope 130 is fixed by another part of the fixing members 150, where the number ratio of the fixing members 150 corresponding to the first adjusting rope 120 and the second adjusting rope 130 may be specifically set according to actual needs.
It should be noted that, the specific materials of the first adjusting rope 120 and the second adjusting rope 130 are not limited in this embodiment, and only the first adjusting rope 120 and the second adjusting rope 130 can achieve stable bending of the insertion portion, for example, the first adjusting rope 120 and the second adjusting rope 130 may be steel wire ropes, nylon ropes, fiber ropes or other material ropes.
To facilitate understanding of the bending process of the bending mechanism 100, taking fig. 1 or fig. 4 as an example, the rotating wheel 110 is first rotated counterclockwise so that the second adjustment rope 130 is wound on the bending surface 111, thereby making the second adjustment rope 130 in a tightened state; at the same time, the first adjusting rope 120 is released from the bending surface 111, so that the first adjusting rope 120 is in a loose state, and thus, the elastic tube sleeved on the adjusting rope is bent, and the inserting part connected to the adjusting rope is bent downwards, so that the direction of the inserting part is adjusted; similarly, the rotating wheel 110 is rotated clockwise, so that the first adjusting rope 120 is wound on the bending surface 111, and the first adjusting rope 120 is in a tightened state; at the same time, the second adjusting wire 130 is released from the bending surface 111, so that the second adjusting wire 130 is in a loose state, and thus, the insertion portion connected to the adjusting wire is bent upward.
Further, referring to fig. 2 and 3, the rotating wheel 110 is provided with a first guiding portion 114 and a second guiding portion 115. The first guiding portion 114 and the second guiding portion 115 are located in the bending groove 1111 at intervals, and a first guiding through hole 1141 and a second guiding through hole 1151 are respectively and correspondingly arranged on the first guiding portion 114 and the second guiding portion 115. The first adjustment cord 120 passes out of the first guide through hole 1141 and onto the mounting surface 112. The second adjustment cord 130 is threaded out of the second guide through hole 1151 onto the mounting surface 112. As can be seen from the above, during the installation of the bending mechanism 100, the first adjusting rope 120 passes through the first guiding through hole 1141 from the side of the rotating wheel 110 along the bending groove 1111, and passes out from the first guiding through hole 1141, and winds around the installation surface 112; the second adjusting cord 130 is threaded into the second guide through hole 1151 from the other side of the rotating wheel 110 along the bending groove 1111 and out from the second guide through hole 1151 to be wound around the mounting surface 112. In this embodiment, the first guiding portion 114 and the second guiding portion 115 are disposed in the bending groove 1111, so that the first adjusting rope 120 and the second adjusting rope 130 are smoother in the winding or releasing process, so that the inserting portion can better implement the bending operation. Meanwhile, the first adjusting rope 120 and the second adjusting rope 130 are further limited by the first guiding portion 114 and the second guiding portion 115 in the bending process, so that shaking of the adjusting ropes in the bending process is reduced, and stability of the bending mechanism 100 is improved. In particular, in the present embodiment, the first guide part 114 and the second guide part 115 are respectively disposed at both ends of the bending groove 1111, so that the guiding effect on the first adjustment cord 120 and the second adjustment cord 130 is greater, and the bending mechanism 100 is more stable.
In one embodiment, referring to fig. 1 and 5, the bending mechanism 100 further includes a fixing member 150. The mounting surface 112 is provided with a mounting groove 1121. The first and second adjustment cords 120 and 130 are each coupled within the mounting slot 1121 by a fastener 150. In this way, the fixing member 150 is connected in the mounting groove 1121, which not only facilitates the mounting operation of the fixing member 150 on the mounting surface 112, but also facilitates the lowering of the height of the fixing member 150 on the mounting surface 112, so that the first adjusting rope 120 and the second adjusting rope 130 are arranged close to the mounting surface 112, and the bending mechanism 100 cannot be normally used due to easy detachment of the rotating wheel 110 when the first adjusting rope 120 or the second adjusting rope 130 is in a loose state, thus being beneficial to ensuring the stable operation of the bending mechanism 100.
Optionally, referring to fig. 1, the first adjusting rope 120 and the second adjusting rope 130 are connected in the mounting groove 1121 through the fixing member 150 by the following implementation manners: the fixing member 150 is a bolt or a screw, by which the first and second adjustment ropes 120 and 130 are fixed to the mounting surface 112; or the fixing member 150 is an adhesive, and the first and second adjustment ropes 120 and 130 are adhered to the installation groove 1121 by the adhesive; or the fixing piece 150 is of a fastening structure, and the first adjusting rope 120 and the second adjusting rope 130 are fastened in the mounting groove 1121 through the fastening structure, wherein when the fixing piece 150 is of the fastening structure, the first adjusting rope 120 and the second adjusting rope 130 can be connected to the fastening structure through a knotting mode or a bolt and screw fixing mode.
Alternatively, referring to fig. 1 and 5, the number of the mounting slots 1121 may be one or more than two.
