Detailed implementation manners
[0017] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the art in the field to which the present invention belongs. The words such as "including" used herein are intended to mean that the elements or items appearing before the word cover the elements or items listed after the word and their equivalents, without excluding other elements or items.
[0018] In view of the problems existing in the prior art, an embodiment of the present invention provides an esophageal foreign body removal device. As Figure 1 shown, the esophageal foreign body removal device includes a grip 1 for a staff member to hold during operation. The pipe 2 is communicatively connected to the grip 1. Specifically, the pipe 2 is fixed to the left end of the grip 1, and the length of the pipe 2 can be adjusted in real time as needed.
[0019] The support cylinder 3 is communicatively connected to the end of the pipe 2 away from the grip 1 (which can be understood as the left end). The esophageal amplification mechanism 4 is provided on the support cylinder 3; the clamping mechanism 5 is provided in the esophageal amplification mechanism 4; the electric drive mechanism 6 is provided on the grip 1. During operation, the electric drive mechanism 6 first drives the clamping mechanism 5 to clamp the foreign body, and then drives the esophageal amplification mechanism 4 to amplify the esophagus, so as to separate both ends of the foreign body from the esophageal wall by increasing the diameter of the esophagus, and then the device is removed from the esophagus, and the foreign body can be removed synchronously.
[0020] In one embodiment, as Figure 2 and Figure 3 shown, the esophageal amplification mechanism 4 includes a first amplification plate 41 slidably connected to the end of the support cylinder 3 away from the grip 1 (which can be understood as the left end); the second amplification plate 42 is slidably connected to the end of the support cylinder 3 away from the grip 1, the second amplification plate 42 is provided above the first amplification plate 41, and the second amplification plate 42 and the first amplification plate 41 move away from each other to amplify the diameter of the esophagus. For the description of the related structures below, the structures connected to the first amplification plate 41 and the second amplification plate 42 are the same. To avoid repetition, the applicant only describes the structures connected to the second amplification plate 42.
[0021] The first moving groove 43 is formed in the support cylinder 3. One end (which can be understood as the upper end) of the first guiding and supporting assembly 44 is connected to the second amplification plate 42, and the other end (which can be understood as the lower end) is connected to the bottom wall of the first moving groove 43. The first guiding and supporting assembly 44 is used for guiding and limiting the movement of the second amplification plate 42 and providing a restoring force for the reset of the second amplification plate 42.
[0022] Specifically, when the first amplification plate 41 and the second amplification plate 42 move closer or farther away from each other, due to the existence of the first guiding and supporting assembly 44, the first amplification plate 41 and the second amplification plate 42 will only move upward or downward in the vertical direction.
[0023] In one embodiment, as Figure 3 shown, the first guiding and supporting assembly 44 includes a first guiding support rod 441 which is fixedly arranged on the second amplification plate 42; a first guiding support cylinder 442 which is fixedly arranged on the bottom wall of the first moving groove 43; a first guiding support spring 443 which is wound outside the first guiding support rod 441, and two ends of the first guiding support spring 443 are respectively fixedly connected to the side wall of the first guiding support rod 441 and the outer side wall of the first guiding support cylinder 442. In this embodiment, the first guiding and supporting assembly 44 includes a combined structure of the first guiding support rod 441, the first guiding support cylinder 442 and the first guiding support spring 443, but is not limited to the above combined structure, which will not be elaborated here.
[0024] In one embodiment, as Figure 2 、as Figure 4 and as Figure 6 shown, the clamping mechanism 5 includes a first clamping plate 51 which is movably arranged between the first amplification plate 41 and the second amplification plate 42; a second clamping plate 52 which is movably arranged between the first amplification plate 41 and the second amplification plate 42, the second clamping plate 52 is movably arranged above the first clamping plate 51, and a clamping area for clamping foreign objects is formed between the second clamping plate 52 and the first clamping plate 51. The connecting assembly 53 There are two connecting assemblies 53, and the two connecting assemblies 53 are respectively used for connecting the first clamping plate 51 and the second clamping plate 52 to the electric driving mechanism 6. The structures of the two connecting assemblies 53 are the same, and only a single connecting assembly 53 will be described later.
[0025] In one embodiment, as Figure 4 and Figure 6As shown, the connecting component 53 includes an extension plate 531, and the extension plate 531 is connected to the electric drive mechanism 6. In one example, the extension plate 531 is disposed in contact with the support cylinder 3, and the extension plate 531 has an L-shaped structure. A second moving groove 532 is formed in the extension plate 531; one end (which can be understood as the upper end) of the second guiding and supporting component 533 is fixedly disposed on the top wall of the second moving groove 532, and the other end (which can be understood as the lower end) of the second guiding and supporting component 533 is fixedly connected to the first sliding block 534. The first sliding block 534 is slidably disposed in the second moving groove 532, and the first sliding block 534 is fixed to the second clamping plate 52.
[0026] In one embodiment, as Figure 5 shown, the second guiding and supporting component 533 includes a second guiding support rod 5331, and the second guiding support rod 5331 is fixedly disposed on the upper end surface of the first sliding block 534; a second guiding support cylinder 5332 is fixedly disposed on the top wall of the second moving groove 532, and the second guiding support cylinder 5332 is movably sleeved outside the second guiding support rod 5331; a second guiding support spring 5333 is wound outside the second guiding support rod 5331, and two ends of the second guiding support spring 5333 are respectively fixedly connected to the side wall of the second guiding support rod 5331 and the outer side wall of the second guiding support cylinder 5332.
[0027] In one embodiment, as Figure 1 and Figure 3 shown, the electric drive mechanism 6 includes a drive cylinder 61, and the drive cylinder 61 is fixedly disposed on the handle 1; a push rod 62 is fixedly disposed on the drive end of the drive cylinder 61, and the push rod 62 is movably disposed in the pipe 2; a cross rod assembly 63 is movably disposed in the pipe 2 and the support cylinder 3. The cross rod assembly 63 is connected to one end of the push rod 62 away from the drive cylinder 61, and the cross rod assembly 63 is connected to the extension plate 531. The setting of the cross rod assembly 63 can play a role in supporting and limiting, so that the central axis of the push rod 62 always coincides with the central axis of the support cylinder 3.
[0028] In one embodiment, as Figure 6As shown, the cross bar assembly 63 includes a first cross bar 631 which is connected to the push-pull rod 62; a second cross bar 633 which is connected to the extension plate 531; and a third guiding and supporting assembly 632 disposed between the first cross bar 631 and the second cross bar 633 and for connecting the first cross bar 631 and the second cross bar 633. The third guiding and supporting assembly 632 includes a third guiding and supporting rod 6321 connected to the second cross bar 633, a third guiding and supporting cylinder 6322 connected to the first cross bar 631. The third guiding and supporting cylinder 6322 is movably sleeved outside the third guiding and supporting rod 6321, and a third guiding and supporting spring 6323 wound around the third guiding and supporting rod 6321. Two ends of the third guiding and supporting spring 6323 are respectively fixedly connected to the side wall of the third guiding and supporting rod 6321 and the outer side wall of the third guiding and supporting cylinder 6322.
[0029] In one embodiment, as Figure 6 shown, the esophageal foreign body removal device further includes a mechanical driving mechanism 7 for synchronously driving the first amplification plate 41 and the second amplification plate 42 to move away from or close to each other, and driving the first clamping plate 51 and the second clamping plate 52 to move close to or away from each other. The mechanical driving mechanism 7 includes a limit block 71 fixedly disposed in the support cylinder 3. The limit block 71 is disposed on the left side of the second cross bar 633 and is used for limiting the leftward movement of the second cross bar 633. A second moving plate 72 is disposed between the first cross bar 631 and the second cross bar 633 and is close to the second cross bar 633. The second moving plate 72 is movably disposed in a third moving groove 78 opened on the support cylinder 3. One end (which can be understood as the right end) of a second push-pull rod 73 is hinged to the second moving plate 72, and the other end (which can be understood as the left end) of the second push-pull rod 73 is hinged to the second amplification plate 42. One end (which can be understood as the right end) of a third push-pull rod 74 is hinged to the second moving plate 72, and the other end (which can be understood as the left end) of the second push-pull rod 73 is hinged to the second clamping plate 52.
[0030] To avoid the situation that the device gets stuck, in one embodiment, as Figure 6As shown, the esophageal foreign body extraction device further includes an anti - jamming component disposed between the second push rod 73 and the second amplification plate 42 and used for connecting the second push rod 73 and the second amplification plate 42. The anti - jamming component includes a second sliding block 75. The second sliding block 75 is hinged to the second push rod 73. The second sliding block 75 is movably arranged in a second moving groove 76. The second moving groove 76 is opened on the second amplification plate 42. A return spring 77 is disposed in the second moving groove 76. One end of the return spring 77 is fixedly connected to the second sliding block 75, and the other end of the return spring 77 is fixedly connected to the side wall of the second moving groove 76.
[0031] Specifically, since the second amplification plate 42 can only move in the vertical direction, when the second clamping plate 52 moves leftward relative to the second amplification plate 42, the second sliding block 75 can avoid the device from being jammed through its movement in the second moving groove 76.
[0032] In one example, a monitor (not shown) is provided at the left end of the esophageal amplification mechanism 4 and / or the clamping mechanism 5. The presence of the monitor is used to monitor the situation inside the esophagus and the accurate position of the foreign body in real - time. The setting of this monitor can improve the intelligence level of the esophageal foreign body extraction device, making the operation process of the esophageal foreign body extraction device more convenient and accurate. In this way, it can not only improve the efficiency of taking out the foreign body, but also avoid excessive damage to the esophageal wall.
[0033] In the esophageal foreign body extraction device of the present invention, the structural design is reasonable and has two movement processes. The first movement process is that the work of the clamping mechanism 5 is prior to that of the esophageal amplification mechanism 4 for positioning the position of the foreign body. The second movement process is that the amplification of the esophageal wall by the esophageal amplification mechanism 4 and the clamping and fixing of the foreign body by the clamping mechanism 5 are carried out simultaneously. In this way, through the amplification of the esophageal diameter by the esophageal amplification mechanism 4, during the amplification process, the foreign body automatically detaches from the esophageal wall. And the working processes of the esophageal amplification mechanism 4 and the clamping mechanism 5 are driven by the same driving source, which can not only reduce the production cost but also improve the extraction efficiency.
[0034] During operation, in one example, the monitor monitors the position of the foreign object. In another example, a peripheral imaging device is used to locate the position of the foreign object. When the position of the foreign object is determined, the driving cylinder 61 is activated. The activation of the driving cylinder 61 will push the cross bar assembly 63 to move leftward through the push rod 62. The initial movement of the cross bar assembly 63 will drive the second clamping plate 52 and the first clamping plate 51 to move leftward relative to the first amplification plate 41 and the second amplification plate 42 through the extension plate 531, causing the second clamping plate 52 and the first clamping plate 51 to move outside the first amplification plate 41 and the second amplification plate 42, and making the second clamping plate 52 and the first clamping plate 51 move to both sides of the foreign object. The later movement of the cross bar assembly 63 starts when the second cross bar 633 abuts against the limit block 71. At this time, due to the abutment of the limit block 71, the second cross bar 633 can no longer move leftward. As the push rod 62 continues to move leftward, it will push the first cross bar 631 to move leftward relative to the second cross bar 633. During this process, the leftward movement of the first cross bar 631 will push the second moving plate 72 to move leftward in the third moving groove 78. The movement of the second moving plate 72 will push the first amplification plate 41 and the second amplification plate 42 to move away from each other through the second push rod 73 to expand the diameter of the esophagus. The third push rod 74 is used to push the second clamping plate 52 and the first clamping plate 51 to move closer to each other to clamp and fix the foreign object through the second clamping plate 52 and the first clamping plate 51, so that during the above process, the foreign object is removed from the esophageal wall.
[0035] Although the embodiments of the present invention have been described in detail above, it is obvious to those skilled in the art that various modifications and changes can be made to these embodiments. However, it should be understood that such modifications and changes are all within the scope and spirit of the present invention. Moreover, the present invention described herein can have other embodiments and can be implemented or realized in various ways.
