Description

Technical Field

[0001] The present invention relates to the technical field of ureter manufacturing equipment, and in particular to a ureter perforating equipment and a use method thereof. Background Art

[0002] Ureteral perforation equipment is mainly used for minimally invasive surgery under ureteroscopy. It can accurately perforate the ureteral stent to establish a channel for stone removal, stricture dilation and other operations. The equipment can reduce surgical trauma, improve surgical accuracy and safety, and shorten patient recovery time. It is one of the important surgical tools in urology.

[0003] In the prior art, when punching the ureter, since the material of the ureter itself is relatively soft, the ureter is very easy to deform under the punching pressure during the punching process. This deformation not only interferes with the accuracy of the punching operation, but also causes deviations in the punching position, thereby affecting the punching effect. For this reason, the present application provides a ureteral punching device and a method of using the same to meet the needs. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and provide a ureteral perforation device and a method of using the same.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a ureteral perforation device, comprising a perforation device workbench, the top of which is fixedly connected to a support seat, the top of which is slidably connected to a puncher, and the side of which is provided with an inner support assembly;

[0006] The inner support assembly includes a first fixed block, the inner cavity of the first fixed block is slidably connected to a support rod, the outer surface of the first fixed block is fixedly connected to a third fixed block, the outer surface of the support rod is fixedly connected to a second fixed block, the sides of the second fixed block and the third fixed block are rotatably connected to a first connecting rod and a second connecting rod, the top of the second fixed block is fixedly connected to a first flexible support plate, and the side of the first flexible support plate is provided with a second flexible support plate.

[0007] As a preferred embodiment, a groove is formed on the outer surface of the second flexible support plate, a side surface of the second flexible support plate is slidably connected to a limit plate, and one end of the limit plate is fixedly connected to one end of the first flexible support plate.

[0008] The technical effect of adopting the above technical solution is: by setting the limiting plate, the movement trajectory of the second flexible support plate can be limited.

[0009] As a preferred embodiment, a telescopic rod is fixedly connected to the top of the first support plate, a second fixing plate is fixedly connected to the top of the telescopic rod, and a first limiting block is fixedly connected to the top of the second fixing plate.

[0010] The technical effect of adopting the above technical solution is: by setting the telescopic rod, the movement distance of the first support plate can be compensated, and by setting the first limit block, the movement trajectory of the flexible splint can be limited.

[0011] A method for using a ureteral perforation device, the specific steps of the method for using the ureteral perforation device are as follows:

[0012] S1. The middle parts of the first connecting rod and the second connecting rod are rotatably connected by a rotating shaft. When in use, the ureter to be punched is firstly sleeved on the outer surface of the first flexible support plate. After the sleeve is completed, the driving module arranged on the side of the second transmission rod is started, so that the support rod can be prompted to move backward along the inner cavity of the first fixed block. When the support rod moves, the first connecting rod and the second connecting rod can be driven to move backward through the second fixed block. Through the cooperation of the first connecting rod and the second connecting rod, the first flexible support plate and the second flexible support plate can be prompted to expand outward. When the second fixed block moves to a certain position, the outer surfaces of the first flexible support plate and the second flexible support plate contact the inner wall of the ureter, so as to achieve the effect of internally supporting and fixing the ureter and sharing the stress at the same time, and avoid the deformation of the ureter due to the punching pressure during the punching process;

[0013] S2. After the inner support is fixed, the puncher is started and the puncher moves downward, thereby driving the first transmission rod to move downward. When the first transmission rod moves downward, the first support plate can be driven downward, and the second fixed plate is fixedly connected to the inner wall of the workbench of the punching equipment. When the first support plate moves downward, the telescopic rod and the second fixed plate cooperate to compensate for the movement distance of the first support plate. When the first support plate moves downward, the connecting plate can be driven to move clockwise through the first fixed plate. When the connecting plate moves clockwise, the flexible splint can be driven to slide along the top of the first limit block toward the middle of the first support plate through the second support plate, thereby achieving the effect of fixing the position of the ureter through the flexible splint, thereby avoiding changes in the position of the ureter during the punching process, which may cause damage;

[0014] S3. After punching is completed, the puncher moves upward. Similarly, when the puncher moves upward, it can drive the first transmission rod to move upward. When the first transmission rod moves upward, the first fixed plate, the connecting plate and the second supporting plate cooperate to cause the flexible splint to loosen the clamping of the ureter. At the same time, when the puncher moves upward, the first limiting rod can be driven downward by the second transmission rod, so that the first limiting rod can be driven to move along the top of the second limiting block, thereby achieving the effect of driving the second transmission rod to slide through the sliding plate. When the sliding plate slides, the mounting block can be driven to move synchronously through the connecting rod, thereby achieving the effect of driving the ureter to perform multiple holes according to a predetermined distance, greatly improving the work efficiency. During the sliding process of the sliding plate, the spring sheet is compressed, thereby causing the positioning block to move downward. When the sliding plate moves to a certain position, the spring sheet releases stress, thereby causing one end of the positioning block to engage with the inner cavity of the slide groove, thereby achieving the effect of fixing the position of the sliding plate, thereby avoiding the problem that the position of the ureter changes during the punching process, resulting in the position of the punching being offset.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are:

[0016] By setting a puncher, the ureter can be punched, and by setting a support seat, the movable component can be supported. First, the ureter is sleeved on the outer surface of the first flexible support plate, and by starting the driving module set on the side of the first fixed block, the support rod can be driven to move backward along the inner cavity of the first fixed block. When the support rod moves backward, it can drive the second fixed block to move backward. When the second fixed block moves backward, the first connecting rod and the second connecting rod cooperate to promote the first flexible support plate and the second flexible support plate to move outward. When the first flexible support plate moves to a certain position, the outer surface of the first flexible support plate contacts the inner wall of the ureter, thereby supporting the inner cavity of the ureter and distributing the stress generated during the punching process to reduce the influence of the stress on the shape of the ureter, and avoiding changes in the shape of the ureter during the processing, which leads to errors in the formed holes.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: a ureteral perforation device and a method for using the same, comprising a perforation device workbench 1, a support seat 12 is fixedly connected to the top of the perforation device workbench 1, a puncher 11 is slidably connected to the top of the perforation device workbench 1, and an inner support assembly 2 is provided on the side of the puncher 11;

[0029] The inner support assembly 2 includes a first fixed block 21, the inner cavity of the first fixed block 21 is slidably connected to a support rod 22, the outer surface of the first fixed block 21 is fixedly connected to a third fixed block 24, the outer surface of the support rod 22 is fixedly connected to a second fixed block 23, the sides of the second fixed block 23 and the third fixed block 24 are rotatably connected to a first connecting rod 25 and a second connecting rod 26, the top of the second fixed block 23 is fixedly connected to a first flexible support plate 27, the side of the first flexible support plate 27 is provided with a second flexible support plate 28, the outer surface of the second flexible support plate 28 is provided with a groove 29, the side of the second flexible support plate 28 is slidably connected to a limiting plate 210, one end of the limiting plate 210 is fixedly connected to one end of the first flexible support plate 27, by setting a puncher 11, the ureter can be punched, by setting a support seat 12, the moving assembly 4 can be supported, firstly, the ureter is sleeved on the outer surface of the first flexible support plate 27, by starting the support seat 12 provided on the first fixed block 2 1, so that the support rod 22 can be driven to move backward along the inner cavity of the first fixed block 21. When the support rod 22 moves backward, the second fixed block 23 can be driven to move backward. When the second fixed block 23 moves backward, the first connecting rod 25 and the second connecting rod 26 cooperate to promote the first flexible support plate 27 and the second flexible support plate 28 to move outward. When the first flexible support plate 27 and the second flexible support plate 28 move outward, the limiting plate 210 can limit the movement trajectory of the first flexible support plate 27 and the second flexible support plate 28 to avoid position deviation during the movement. When the first flexible support plate 27 moves to a certain position, the outer surface of the first flexible support plate 27 contacts the inner wall of the ureter, so as to support the inner cavity of the ureter and distribute the stress generated during the punching process to reduce the influence of the stress on the shape of the ureter, so as to avoid the shape of the ureter changing during the processing, resulting in errors in the formed holes.

[0030] Further, such as Figure 1 , Figure 2 and Figure 4As shown: a fixing assembly 3 is provided at the bottom of the first flexible support plate 27, and the fixing assembly 3 includes a first transmission rod 31, one end of the first transmission rod 31 is fixedly connected to the first support plate 32, the top of the first support plate 32 is fixedly connected to the first fixing plate 33, the inner cavity of the first fixing plate 33 is rotatably connected to the connecting plate 34, one end of the connecting plate 34 is rotatably connected to the second support plate 35, the top of the second support plate 35 is fixedly connected to the flexible clamping plate 36, the top of the first support plate 32 is fixedly connected to the telescopic rod 37, the top of the telescopic rod 37 is fixedly connected to the second fixing plate 38, the top of the second fixing plate 38 is fixedly connected to the first limit block 39, and the side of the support seat 12 is provided with a moving assembly Part 4, the moving assembly 4 includes a second transmission rod 41, the inner cavity of the second transmission rod 41 is rotatably connected to the first limit rod 42, the bottom of the first limit rod 42 is provided with a sliding plate 43, the bottom of the sliding plate 43 is provided with a second limit block 44, and the side of the second limit block 44 is provided with a positioning block 45. After the internal support is fixed, the puncher 11 is started, and the puncher 11 moves downward, thereby driving the first transmission rod 31 to move downward. When the first transmission rod 31 moves downward, it can drive the first support plate 32 to move downward. The second fixed plate 38 is fixedly connected to the inner wall of the punching equipment workbench 1. When the first support plate 32 moves downward, the telescopic rod 37 and the second fixed plate 38 cooperate, so that The movement distance of the first support plate 32 can be compensated. When the first support plate 32 moves downward, the first fixing plate 33 can drive the connecting plate 34 to move clockwise. When the connecting plate 34 moves clockwise, the second support plate 35 can drive the flexible splint 36 to slide along the top of the first limit block 39 toward the middle of the first support plate 32, thereby achieving the effect of fixing the position of the ureter through the flexible splint 36 to avoid changes in the position of the ureter during the punching process, resulting in damage. After punching is completed, the puncher 11 moves upward. Similarly, when the puncher 11 moves upward, it can drive the first transmission rod 31 to move upward. When the movable rod 31 moves upward, the first fixed plate 33, the connecting plate 34 and the second supporting plate 35 cooperate to prompt the flexible splint 36 to loosen the clamp on the ureter. At the same time, when the puncher 11 moves upward, the first limiting rod 42 can be driven downward by the second transmission rod 41, thereby prompting the first limiting rod 42 to move along the top of the second limiting block 44, thereby achieving the effect of driving the second transmission rod 41 to slide through the sliding plate 43. When the sliding plate 43 slides, the mounting block 410 can be driven to move synchronously through the connecting rod 49, thereby achieving the effect of driving the ureter to perform multiple holes according to a predetermined distance, thereby greatly improving work efficiency.

[0031] During the movement of the mounting block 410, since the sliding plate 43 and the punching equipment workbench 1 are in a sliding connection state, the position of the mounting block 410 may be offset during the punching process. Figure 5 As shown: a second limiting rod 48 is provided on one side of the sliding plate 43, and a connecting rod 49 is fixedly connected to the other side of the sliding plate 43, one end of the connecting rod 49 is fixedly connected to the mounting block 410, and a spring piece 46 is fixedly connected to the bottom of the positioning block 45, and a slide groove 47 is provided on the top of the sliding plate 43. During the sliding process of the sliding plate 43, the spring piece 46 is compressed, thereby prompting the positioning block 45 to move downward. When the sliding plate 43 moves to a certain position, the spring piece 46 releases the stress, thereby prompting one end of the positioning block 45 to engage with the inner cavity of the slide groove 47, thereby achieving the effect of fixing the position of the sliding plate 43, avoiding the problem that the position of the mounting block 410 changes during the punching process, resulting in the position of the punching being offset.

[0032] Example

[0033] like Figure 1-5 As shown: The specific steps of using the ureteral perforation device are as follows:

[0034] S1. When in use, the ureter that needs to be punched is firstly sheathed on the outer surface of the first flexible support plate 27. After the sheathing is completed, the driving module arranged on the side of the second transmission rod 41 is started, so that the support rod 22 can be prompted to move backward along the inner cavity of the first fixed block 21. When the support rod 22 moves, the first connecting rod 25 and the second connecting rod 26 can be driven to move backward through the second fixed block 23, thereby achieving the effect of driving the first flexible support plate 27 and the second flexible support plate 28 to expand outward. When the second fixed block 23 moves to a certain position, the outer surfaces of the first flexible support plate 27 and the second flexible support plate 28 are in contact with the inner wall of the ureter, so that the ureter can be supported internally;

[0035] S2. After the inner support is fixed, the puncher 11 is started, and the puncher 11 moves downward, thereby driving the first transmission rod 31 to move downward. When the first transmission rod 31 moves downward, the first support plate 32 can be driven downward, thereby achieving the effect of driving the connecting plate 34 to move clockwise through the first fixing plate 33. When the connecting plate 34 moves clockwise, the flexible splint 36 can be driven by the second support plate 35 to slide along the top of the first limit block 39 toward the middle of the first support plate 32, thereby achieving the effect of fixing the position of the ureter through the flexible splint 36.

[0036] S3. After punching is completed, the puncher 11 moves upward. Similarly, when the puncher 11 moves upward, it can drive the first transmission rod 31 to move upward. When the first transmission rod 31 moves upward, the first fixing plate 33, the connecting plate 34 and the second supporting plate 35 cooperate to prompt the flexible splint 36 to loosen the clamping of the ureter. At the same time, when the puncher 11 moves upward, the first limiting rod 42 can be driven downward by the second transmission rod 41, thereby prompting the first limiting rod 42 to move along the top of the second limiting block 44, and then the sliding plate 43 can be used to drive the second transmission rod 41 to slide. During the sliding process of the sliding plate 43, the spring sheet 46 is compressed, thereby prompting the positioning block 45 to move downward. When the sliding plate 43 moves to a certain position, the spring sheet 46 releases stress, thereby prompting one end of the positioning block 45 to engage with the inner cavity of the slide groove 47, thereby achieving the effect of fixing the position of the sliding plate 43.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
