Description

Technical Field

[0001] This application belongs to the field of medical device technology, specifically a wire support. Background Technology

[0002] Endoscopes connect to the endoscope video processor or other equipment interfaces via endoscope system connection cables. These connection cables are relatively expensive. To ensure proper endoscope use, doctors need to be able to drag the endoscope, requiring redundant cable lengths. This can lead to bending during use. Under gravity, the cable can easily sag to the ground. Furthermore, in clinical use, the endoscope video processor is placed on a stand. At the connection point between the connection cable and the working interface, the cable sags directly under gravity, requiring the working interface to withstand significant forces. Under the combined effects of gravity and the pulling force applied by medical personnel, the cable at the working interface can easily bend excessively. Over time, the cable can become damaged, affecting signal transmission. Additionally, some cables contain optical fibers for signal transmission; excessive bending of these fibers can also impair signal transmission, thus affecting the quality of the medical images displayed on the screen.

[0003] During surgery, when the doctor adjusts the endoscope, it will cause the connecting cable to move, such as swinging it from side to side or moving it along its axis. If the connecting cable frequently rubs against the ground or collides with other objects on the operating room floor, it can easily damage the cable sheath, which in turn can cause mechanical damage or chemical corrosion to the internal circuitry of the connecting cable, making it difficult for the connecting cable to transmit signals accurately. Utility Model Content

[0004] To better protect the connection cables of the endoscope system and ensure that the connection cables can accurately transmit signals, this application provides a cable support.

[0005] A wire support includes a base and a working component. The working component is pivotally connected to the base via a first pivot axis. The working component has a bearing surface capable of bearing wires. The bearing surface is an arc-shaped surface. The projection of the bearing surface in a longitudinal section of the first pivot axis is a first projection. The first projection extends radially outward along the first pivot axis and protrudes upward in a direction parallel to the axial direction of the first pivot axis. The working component also has a first fixing part capable of bearing and restricting wires passing through the bearing surface.

[0006] In one embodiment of this application, the working piece is provided with a wire-blocking part, which is located on both sides of the extending direction of the bearing surface. The wire-blocking part and the working piece form a wire-passing channel, and the bearing surface is the bottom surface of the wire-passing channel.

[0007] In one embodiment of this application, one end of the first projection is pivotally connected to the base via a first pivot shaft, and the other end is provided with a first fixing part.

[0008] In one embodiment of this application, the base is provided with a second fixing part that can fix the wire, and the wire can reach the first fixing part through the second fixing part and the wire passage.

[0009] In one embodiment of this application, the base is provided with at least two sets of second fixing parts capable of fixing wires, and the at least two sets of second fixing parts are arranged in an array along a direction parallel to the axial direction of the first pivot axis.

[0010] In one embodiment of this application, the base is provided with a spring clip, the pivot axis of which is perpendicular to the first pivot axis.

[0011] In one embodiment of this application, the base is further connected to a telescopic rod, which is located below the working part and can extend away from the working part.

[0012] In one embodiment of this application, the first fixing part is a cable tray.

[0013] In one embodiment of this application, the base is provided with a second fixing part capable of fixing the wire, the second fixing part being a wire clamping groove.

[0014] In one embodiment of this application, the working part is connected to the first pivot shaft via a bearing, and / or the first pivot shaft is connected to the base via a bearing.

[0015] The beneficial effects of this application are at least as follows:

[0016] 1. After the connecting cable is connected to the working interface, it passes through the bearing surface of the cable in this application and reaches the endoscope. The signal obtained by the endoscope can reach the endoscope video processor or other equipment through the connecting cable. Of course, other cables can also be carried by the bearing surface. Since the bearing surface is an upward convex arc, the cable can be supported by the bearing surface, avoiding excessive bending of the cable and damage to the internal circuitry of the cable. On the other hand, since the bearing surface can support the cable, it can prevent the cable from falling to the ground, reducing the collision and friction between the cable and the ground or other objects, which is beneficial to protecting the optical fiber and other components inside the cable.

[0017] 2. The first fixing part can bear and restrict the wire passing through the bearing surface. The working part is pivotally connected to the base through the first pivot shaft. When the wire is pulled by medical staff and swings left and right in the horizontal plane, the working part can swing left and right in the horizontal plane to adapt to the change of wire angle and support the wire. Since the working part can swing left and right with the wire, the friction between the working part and the wire can be reduced, thereby reducing the possibility of wire damage.

[0030] Please see Figures 1 to 5 Learn more about this application.

[0031] See Figure 1The wire support includes a base 101 and a working component 201. The working component 201 is pivotally connected to the base 101 via a first pivot shaft 102. The working component 201 has a bearing surface 202 capable of bearing the wire 303. The bearing surface 202 is an arc-shaped surface. The projection of the bearing surface 202 in a longitudinal section of the first pivot shaft 102 is the first projection. (See [reference]) Figure 2 The first projection extends radially outward along the first pivot axis 102 and protrudes upward in a direction parallel to the axial direction of the first pivot axis 102; the working part 201 is also provided with a first fixing part 203, which can bear and restrict the wire 303 passing through the bearing surface 202, see [reference]. Figure 3 The first fixing part 203 provides support force to the wire 303 to overcome the weight of the wire 303 itself, prevent the wire 303 from falling to the ground, and restrict the left and right movement of the wire 303 in the horizontal plane in the direction of extension of the working part 201, so that the wire 303 can always be located on the bearing surface 202.

[0032] Cable 303 can connect to the working interface of endoscope video processor 302 or other equipment. When the base 101 of the cable bracket is fixed to the mounting bracket 301 on which the endoscope video processor 302 or other equipment is placed by bolts or spring clips 104, see [reference needed]. Figure 4 The first pivot axis 102 is in a vertical position, and the working part 201 is pivotally connected to the base 101 via the first pivot axis 102, so that the working part 201 can swing left and right relative to the base 101 in the horizontal plane. See [reference needed] Figure 5 Therefore, when medical staff move the cable 303 through the endoscope, the cable 303 can cause the working part 201 to swing left and right in the horizontal plane, adapting to the change in the position of the cable 303. The bearing surface 202 can always support the cable 303, preventing the cable 303 from falling to the ground and rubbing or colliding with the ground or objects on the ground, thereby improving the service life of the cable 303 and avoiding affecting the signal transmission effect of the cable 303. At this time, the first projection protrudes upward, and the cable 303 is supported by the bearing surface 202 at the working interface. The bearing surface 202 can provide support force to the cable 303, helping the cable 303 overcome its own weight and other forces, and preventing the cable 303 from bending too much when subjected to large forces at the connection with the working interface, which would affect the signal transmission effect.

[0033] Since the bearing surface 202 has a gradually upward extending direction, the wire 303 also has an upward extending direction when it is supported by the bearing surface 202. This alleviates the situation where the excessively long wire 303 droops too much when it is between the working interface and the endoscope lens, thereby reducing the possibility of damage to the wire 303.

[0034] See Figures 1 to 4In one embodiment of this application, the working piece 201 is provided with a wire-blocking part 204, which is located on both sides of the extending direction of the bearing surface 202. The wire-blocking part 204 and the working piece 201 form a wire passage. The bearing surface 202 is the bottom surface of the wire passage and is located between the wire-blocking parts 204. The wire 303 connected to the working interface can be connected to the endoscope lens through the wire passage. At the same time, the wire-blocking part 204 and the first fixing part 203 can restrict the wire 303 in the wire passage. During use, the bearing surface 202 can always support the wire 303, and the working piece 201 can rotate left and right around the first pivot axis 102 in the horizontal plane as the position of the wire 303 changes.

[0035] See Figure 2 In one embodiment of this application, one end of the first projection is pivotally connected to the base 101 via the first pivot axis 102, and the other end is provided with a first fixing part 203. By providing the first fixing part 203 at the end of the first projection, the wire 303 can effectively drive the working part 201 to rotate around the first pivot axis 102 in the horizontal plane via the first fixing part 203.

[0036] See Figure 1 , Figure 2 In one embodiment of this application, the base 101 is provided with a second fixing part 103 capable of fixing the wire 303, and the wire 303 can reach the first fixing part 203 through the second fixing part 103 and the wire passage. See also Figure 1 , Figure 4 The second fixing part 103 can fix the wire 303 extending from the working interface and support the wire 303 to prevent the working interface connected to the wire 303 from being damaged due to its own weight or other forces. Furthermore, the combined action of the second fixing part 103, the wire passage, and the first fixing part 203 ensures that the wire 303 is always located in the wire passage, and the bearing surface 202 can always support the wire 303, reducing the degree of sag of the wire 303 and preventing the wire 303 from colliding or rubbing against the ground or other objects.

[0037] In one embodiment of this application, the base 101 is provided with a second fixing part 103 that can fix the wire 303. The second fixing part 103 is a wire-holding groove. The width of the wire-holding groove can be smaller than the outer diameter of the wire 303. The wire 303 can be engaged with the wire-holding groove, so that the second fixing part 103 can fix the wire 303 and provide support for the wire 303. The second fixing part 103 is stationary relative to the working interface, so that the second fixing part 103 can help the wire 303 overcome other forces that cause the wire 303 to move, and prevent the wire 303 from falling out of the working interface or damaging the working interface due to pulling or the influence of the wire 303's own weight.

[0038] See Figure 3 In one embodiment of this application, the base 101 is provided with at least two sets of second fixing parts 103 that can fix the wires 303. The at least two sets of second fixing parts 103 are arranged in an array along a direction parallel to the axial direction of the first pivot axis 102, so that the second fixing parts 103 can fix the wires 303 in layers, avoiding the situation where there are too many wires 303 in the same horizontal plane, resulting in the wires 303 occupying a large width.

[0039] Of course, those skilled in the art to which this application pertains will understand that this application may not require the wire-blocking part 204. If the bearing surface 202 is wide enough, the bearing surface 202 can always bear the wire 303 during the movement of the wire 303. This application may only require the first fixing part 203 and the second fixing part 103, or only require the first fixing part 203. This will not be elaborated further here.

[0040] Since the wire 303 is fixedly connected to the working interface, the working part 201 can move relative to the working interface. If the wire 303 cannot move relative to the first fixing part 203, then when the wire 303 drives the working part 201 to move, the first fixing part 203 may pull the wire 303 between the first fixing part 203 and the working interface. In one embodiment of this application, see [link to relevant documentation]. Figure 1 The first fixing part 203 is a wire support groove. The width of the wire support groove can be greater than the outer diameter of the wire 303. The wire 303 can slide relative to the wire support groove in the wire support groove. So when the working part 201 swings around the first pivot axis 102, the wire support groove will not pull the wire 303, but will only restrict the movement of the wire 303 in the radial direction of the wire 303, thereby preventing the first fixing part 203 from pulling the wire 303 between the first fixing part 203 and the working interface.

[0041] See Figure 3 , Figure 4 In one embodiment of this application, the base 101 is provided with a spring clip 104, the pivot axis of the spring clip 104 is perpendicular to the first pivot axis 102, so that the base 101 can be fixed to the crossbar of the placement frame 301 by the spring clip 104, so that the first pivot axis 102 is set vertically, and the working piece 201 can rotate in the horizontal plane around the first pivot axis 102.

[0042] See Figure 4In one embodiment of this application, the base 101 is also connected to a telescopic rod 105. The telescopic rod 105 is located below the working part 201 and can extend away from the working part 201. The telescopic rod 105 can support the base 101 and prevent the working part 201 from bearing the weight of the large wire 303, or from shaking or even falling off the placement rack 301 when medical staff pull the wire 303. The telescopic rod 105 can be equipped with a locking mechanism, such as one rod having multiple slots along its axial direction, and another rod having a locking strip that can be inserted into one of the slots. When the telescopic rod 105 extends and retracts to a suitable length, the locking mechanism is used to lock the length of the telescopic rod 105. The telescopic rod 105 can provide stable support to the base 101.

[0043] In one embodiment of this application, the working piece 201 is connected to the first pivot shaft 102 via a bearing, and / or the first pivot shaft 102 is connected to the base 101 via a bearing. The first pivot shaft 102 can be connected to the working piece 201 and the base 101 via two bearings respectively, or the first pivot shaft 102 can be fixedly connected to one of the working piece 201 and the base 101, and connected to the other via a bearing. The bearing can reduce the resistance when the working piece 201 rotates relative to the base 101, reduce the force required for medical personnel to swing the working piece 201 in the horizontal plane via the wire 303, and prevent damage to the wire 303.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
