Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a bladder-urethra anastomosis device for urology. Background Art

[0002] In urology, patients who need to undergo prostatectomy due to prostate cancer often need urethral reconstruction, in which the bladder neck is surgically anastomosed to the residual urethra.

[0003] During the bladder-urethra anastomosis, the bladder and urethra have complex anatomical structures, multiple physiological bends and strictures, which increase the difficulty of anastomosis. At the same time, the urethral stump is located at the bottom of the pelvic cavity and is deep, resulting in a narrow surgical field of view. In addition, there are tissues such as the rectum and neurovascular bundles around the urethra, which should be avoided from damage during anastomosis, further increasing the difficulty of anastomosis. During the anastomosis, the anastomotic tension should be properly controlled, not too low or too high, to achieve an aligned anastomosis between the urethral stump and the bladder neck.

[0004] However, in the existing anastomosis devices, the alignment is often done by straight-line pulling to reduce the difficulty of anastomosis, but it is not convenient to align the stump urethra at the bend; and during the anastomosis process, the existing flexible curved anastomosis device may be easily shaken by the operation of medical personnel due to the characteristics of the flexibility of the flexible material, which increases the difficulty of the operation. Therefore, the present invention provides a urological bladder urethra anastomosis device that is easy to operate, which is convenient for aligning the bladder neck with the stump urethra and reduces the shaking phenomenon during anastomosis. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a urological bladder-urethra anastomosis device, which is convenient for aligning the bladder neck with the residual urethra and reduces the shaking phenomenon during anastomosis.

[0006] In order to achieve the above-mentioned object, the technical solution of the present invention is as follows: a urological cystourethral anastomosis device comprises a plurality of hard tubes, wherein a plurality of rotating components for adjusting the rotating direction of the hard tubes are arranged between adjacent hard tubes;

[0007] An adsorption sleeve is slidably fitted on the hard tube, and a hook arranged in a ring shape is provided on the adsorption sleeve;

[0008] A flexible tube is slidably matched in the hard tube, and a driving member for pulling the flexible tube to move is provided in the hard tube, and a conversion assembly for connecting and releasing the adsorption sleeve is provided between the driving member and the adsorption sleeve;

[0009] A medium input pipe for filling the hard pipe is arranged between the flexible pipe and the hard pipe; when the medium input pipe is fully expanded, the medium input pipe abuts against the flexible pipe and the hard pipe.

[0010] The technical principle of the above scheme is as follows: first, the hard tube is gradually sent into the patient's body from the outside of the urethra, and the adjacent hard tubes are rotated by controlling the rotating component to adjust the bending angle to suit the shape of the urethra. The hook on the adsorption sleeve is then controlled by the conversion component to stretch the residual urethra, thereby achieving the alignment of the urethral stump, and then the medium input tube is stably filled to connect the hard tubes to form a whole, thereby ensuring the stability of the device during the anastomosis process.

[0011] The above scheme has the following beneficial effects:

[0012] 1. Compared with the prior art, this solution improves the application range of the device by rotating the components to adapt to urethral shapes with different degrees of curvature, form uniform traction of the urethral stump, reduce excessive tension caused by excessive stretching of the urethral wall in a single direction during the alignment of the urethral stump, and facilitate anastomosis, alignment and suturing.

[0013] 2. This solution, through the use of a conversion component, changes the single traction at the end of the urethral stump into an overall traction of the urethra, so as to reduce local pressure and thereby reduce the occurrence of excessive anastomotic tension.

[0014] 3. Compared with the prior art, this solution improves the overall shape of the hard tube during the anastomosis process by changing the filling of the medium input tube, thereby reducing the displacement of a single hard tube and improving the stability during the anastomosis process.

The end of the medium input tube 42 away from the second capsule 43 is located in the flexible tube 4, and the end of the medium input tube 42 away from the second capsule 43 is connected to a water pump for pumping the medium.

[0060] A medium input pipe 42 for filling the hard pipe 1 is provided between the flexible pipe 4 and the hard pipe 1 ; when the medium input pipe 42 is fully expanded, the medium input pipe 42 abuts against the flexible pipe 4 and the hard pipe 1 .

[0061] The specific implementation process is as follows: First, the entire device is disinfected in advance and data on the patient's condition is collected (including data on the location of tissues such as urethral physiological curvature, stenosis, and rectum and neurovascular bundles). Then, the hard tube 1 is gradually sent into the patient's body from the external urethral opening, and the pumping control parameters of the pneumatic rod 31 and the air pump are input through the control panel. The length change of the pneumatic rod 31 controls the limit block 32 to drive the extension length of the first capsule 3, so that the first capsule 3 around the opening of the hard tube 1 is centered. During the expansion process of the first capsule 3 injected with gas by the external air pump, the expansion rate of the first capsule 3 is controlled to form different degrees of expansion volume through the annular arrangement of the first capsule 3, so that the hard tube 1 rotates in the direction in which it needs to rotate, so as to be suitable for urethral shapes with different degrees of curvature, form a uniform traction of the urethral stump, reduce the excessive stretching of the urethral wall in a single direction during the alignment of the urethral stump, and make it easier to align and suture.

[0062] After the rigid tube 1 is transported to the designated anastomotic position, the motor controls the running wheel 51 to rotate, and the friction between the running wheel 51 and the motor drives the flexible tube 4 to move in the rigid tube 1. When the position where the anastomotic traction is required is reached, the first magnetic rod 23 or the second magnetic rod 24 is adsorbed by the electromagnet 52, so that the adsorption sleeve 2 is fixed by the first magnetic rod 23 or the second magnetic rod 24 to drive the adsorption sleeve 2 to slide on the rigid tube 1, and the slide 11 is used to limit the slider 22 to ensure that the adsorption sleeve 2 slides horizontally on the rigid tube 1. Then, the magnetic pole direction of the electromagnet 52 is controlled to control the first magnetic rod 23 or the second magnetic rod 24 to drive the hook 20 to extend out of the hidden groove 21 to grab and fix the catheter stump, so as to achieve the docking of the urethral stump and the bladder neck. At the same time, by adjusting the magnetic force of the electromagnet 52, the moving distance of the first magnetic rod 23 or the second magnetic rod 24 is controlled, so as to drive the hook 20 to extend out of the hidden groove 21, thereby adjusting the fixed depth, so as to adjust it according to the thickness of the urethral wall. At the same time, the electromagnet 52 pulls the urethra one by one to move, so that the single traction at the end of the urethral stump is changed to the overall traction of the urethra, so as to reduce the local pressure, thereby reducing the occurrence of excessive anastomotic tension.

[0063] After the alignment of the urethral stump is completed, the water pump controls the second bladder 43 to expand through the input of the medium input tube 42, so that the protrusion on the second bladder 43 extends to increase the friction between the hard tube 1 and the surrounding tissue.

[0064] Embodiment 2:

[0065] Combined with Fig.11 As shown, the difference from Example 1 is that the specific implementation process is as follows: in another embodiment, a gear mechanism symmetrically arranged with the driving block 5 as the center is provided in the driving block 5, and the gear mechanism includes a motor 56, and the output end of the motor 56 is coaxially clamped with the main gear 55, the walking wheel 51 is coaxially connected with the worm gear 53, and the turbine is respectively meshed with the worm 54, and a plurality of gear sets are connected between the worm 54 and the main gear 55; the gear set includes a first gear and a second gear, the first gear is coaxially clamped with the worm 54, the second gear is located between the worm 54 and the main gear 55, and the second gear is respectively meshed with the first gear and the main gear 55.

[0066] The specific implementation process is as follows: the main gear 55 drives the second gear to rotate, and the second gear rotates while driving the first gear to rotate, and the first gear drives the meshing turbine to rotate through the worm 54 to control the shape wheel to move outside. The motors 56 on both sides drive the running wheel 51 on one side to rotate through the gear set at the same time to improve energy utilization efficiency and reduce the control difficulty when multiple motors 56 are running, so as to drive the driving block 5 to move inside the hard tube 1 through the running wheel 51.

[0067] Embodiment 3:

[0068] The difference from Example 2 is that the hard tube 1 is a transparent tube, and the driving block 5 is fixedly connected with a plurality of LED lamps (not shown in the figure) for emitting light of different colors.

[0069] The specific implementation process is as follows: During the anastomosis process, the patient's surrounding tissues are understood in advance to determine the distribution of different tissues and whether the surgical field of view needs to be adjusted during the actual anastomosis process, so as to generate control instructions to control the brightness or color of the LED light. The different colors of light formed by the LED light are used to illuminate the surrounding tissues to remind the current position of the urethra and increase the brightness of the surrounding tissues, improve the brightness of the surgical field of view, and reduce the difficulty of external physicians to operate.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
