Description

Technical Field

[0001] The invention specifically relates to a microvascular suturing training platform. Background Art

[0002] Hemodialysis is currently the main renal replacement therapy for patients with end-stage renal disease. Autologous arteriovenous fistulas have become the preferred dialysis access for long-term hemodialysis patients due to their fewer complications and high long-term patency rate. Microvascular suturing technology is the key part of microarteriovenous fistula surgery. By using a microscope and fine suturing technology, the success rate of the operation can be improved and the incidence of postoperative complications can be reduced.

[0003] Microvascular suturing technology is an important part of the field of microsurgery, and its research progress mainly focuses on improving suturing quality, simplifying operation procedures, and reducing surgical risks. In recent years, with the development of science and technology and the increase in clinical needs, microvascular suturing technology has been continuously improved and innovated.

[0004] At present, the traditional method of microvascular suturing technology is manual suturing. Although this method is complex and requires high technical skills of doctors, it is still the most widely recognized standard. However, manual suturing has certain limitations, requiring a long learning curve and high operational difficulty. Therefore, the establishment of a microsuturing surgery training platform can not only improve the doctor's operating skills, but also reduce the risks and incidence of complications in actual surgery by simulating the surgical environment, which helps to improve the treatment effect and survival rate of hemodialysis patients. However, there is currently no platform for training microsuturing surgery. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a microvascular suturing training platform that can be used for microvascular suturing surgery.

[0006] In order to achieve the above-mentioned object, the present invention is implemented through the following technical solutions: a microvascular suturing training platform, including a platform module, a microscopic observation module and a training model module;

[0007] The platform module includes an operating table and a liquid tank, and the liquid tank is arranged at the bottom of the operating table;

[0008] The microscopic observation module comprises a microscope, and the microscope is arranged on an operating table;

[0009] The training model module includes a training model, a blood circulation component and a placement component. The blood circulation component includes a liquid tube and a liquid pump. The blood vessels of the training model are connected to the liquid tank through the liquid tube and the liquid pump to form a loop. The placement component includes a placement board and a fixing belt. The placement board is set on the operating table and can place the training model. The fixing belt is set on the placement board and can fix the training model.

[0010] Place the training model on the placement board, fix the training model with a fixing belt, connect the liquid tube to the training model, and start the liquid pump to form blood circulation in the training model. The user can observe the training model through a microscope and start the simulation training of vascular suture surgery on the training model.

[0011] The beneficial effect of the above-mentioned microvascular suturing training platform is that users can train microvascular suturing surgery through the platform, and can place different training models for use to simulate training for different surgeries, combining theoretical learning with simulated operations to enhance the accumulation of surgical experience.

[0012] Furthermore, the microscope observation module also includes a moving assembly, including a moving seat and a screw. The operating table has a cavity inside, and the screw is rotatably arranged in the cavity. The surface of the operating table is provided with a strip groove connecting to the cavity along the axial direction of the screw. The bottom of the moving seat is threadedly connected to the screw through the strip groove and is slidably connected to the strip groove. The microscope is fixedly set on the moving seat.

[0013] Under the limitation of the strip groove, rotating the screw rod can drive the moving seat to move along the axial direction of the strip groove, thereby adjusting the position of the microscope relative to the training model, so that the microscope can be accurately aligned with the position of the training model.

[0014] Furthermore, the placement assembly further comprises a rotating shaft, a sliding rod and a rotating column, wherein the rotating shaft is arranged in the cavity in a horizontal direction and is rotatable, the sliding rod is arranged on the rotating shaft, the rotating column is arranged in the cavity in a vertical direction and is rotatable, and a plurality of inclined sliding grooves are provided on the circumferential surface of the rotating column around the circumference, and the end of the sliding rod can be inserted into the inclined sliding groove;

[0015] The placement plate is rotatably arranged on the operating table, and the rotation of the rotating column can drive the placement plate to rotate on the operating table.

[0016] By rotating the rotating shaft, the sliding rod can be driven to move circumferentially. After the end of the sliding rod is inserted into the inclined slide groove, it can drive the rotating column to rotate in cooperation with the inclined slide groove, thereby driving the placement plate to rotate on the operating table, so as to adjust the angle of the training model and allow the user to better sew the model.

[0017] Furthermore, the rotating shaft and the screw rod are arranged in parallel, and the ends thereof are both extended out of the operating table and are connected with knobs.

[0018] The ends of the rotating shaft and the screw are both arranged on the side close to the user, which makes it easier for the user to adjust the position of the microscope and the angle of the training model through the knob.

[0019] Furthermore, the placement assembly also includes a driving gear and a driven gear, the rotating column is connected to the driving gear, the placement plate is connected to the driven gear, and the driving gear is meshed with the driven gear.

[0020] The rotating column and the driving gear rotate, which can drive the driven gear and the placement plate to rotate.

[0021] Furthermore, the diameter of the driving gear is smaller than the diameter of the driven gear.

[0022] The diameter of the driving gear is small while the diameter of the driven gear is large, so turning the shaft can drive the placement plate to rotate at a small angle, thereby achieving fine-tuning of the angle of the training model.

[0023] Furthermore, the placement assembly also includes a pressure block and a spring, one end of the pressure block is sleeved on the rotating shaft, and the rotating shaft is provided with limit blocks that fit with both sides of the pressure block, and the other end is provided with a tooth groove that matches the driving gear, and the pressure block is connected to the inner wall of the cavity through a spring.

[0024] When the training model angle needs to be adjusted, the shaft can be pulled first, and the pressure block can be driven to move together through the limit block, so that the tooth groove is separated from the active gear. At this time, the shaft can be rotated to drive the placement plate to rotate through the rotating column. After the adjustment is completed, the shaft is released, and the tooth groove of the pressure block meshes with the active gear under the action of the spring, so that the placement plate is fixed and cannot rotate.

[0025] Furthermore, the material of the fixing belt is elastic, and one end of the fixing belt is fixedly connected to the placement plate, and the other end of the fixing belt is detachably connected to the placement plate via a buckle.

[0026] After the training model is placed on the placement board, the fixing belts are wrapped around both ends and connected to the placement board through buckles. Under the action of the elastic fixing belts, the training model can be pressed onto the placement board. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0037] See also Figures 1 to 4 The present invention provides a microvascular suturing training platform, including a platform module 10, a microscopic observation module 20 and a training model module 30. The user can observe the training model module 30 through the microscopic observation module 20 on the platform module 10, thereby performing simulated surgery training.

[0038] Specifically, the platform module 10 includes an operating table 11 and a liquid tank 12. The operating table 11 is used as a workbench for simulating surgery. The liquid tank 12 is arranged at the bottom of the operating table 11 and is used to store simulated blood. The microscopic observation module 20 includes a microscope 21, which is arranged on the operating table 11. The training model module 30 includes a training model 31, a blood circulation component and a placement component. The blood circulation component includes a liquid tube 321 and a liquid pump 322. The blood vessels of the training model 31 can be connected to the liquid tank 12 through the liquid tube 321 and the liquid pump 322 to form a loop. The placement component includes a placement plate 331 and a fixing belt 332. The placement plate 331 is arranged on the operating table 11 and can place the training model 31. The fixing belt 332 is arranged on the placement plate 331 and can fix the training model 31.

[0039] The training model 31 is placed on the placement board 331, fixed by the fixing belt 332, and then the liquid tube 321 is connected to the training model, and the liquid pump 322 is started to allow blood to circulate in the training model 31. The user can observe the training model 31 through the microscope 21 and start the simulation training of the vascular suture operation on the training model, thereby combining theoretical learning with simulation operation and improving the accumulation of surgical experience.

[0040] Specifically, the microscopic observation module 20 also includes a moving assembly, including a moving seat 221 and a screw 222. The operating table 11 has a cavity inside, and the screw 222 is rotatably arranged in the cavity. The upper surface of the operating table 11 is provided with a strip groove 111 connected to the cavity along the axial direction of the screw 222. The bottom of the moving seat 221 passes through the strip groove 111 and is threadedly connected to the screw 222, and is slidably connected to the strip groove 111. The microscope 21 is fixedly arranged on the moving seat 221. Under the limitation of the strip groove 111, rotating the screw 222 can drive the moving seat 221 to move along the axial direction of the strip groove 111, thereby adjusting the position of the microscope 21 relative to the training model 31, so that the microscope 21 can accurately align with the position of the training model 31.

[0041] Specifically, the placement assembly also includes a shaft 333, a slide bar 334 and a rotating column 335. The shaft 333 is horizontally arranged in the cavity and can be rotated. The slide bar 334 is arranged on the shaft 333. The rotating column 335 is rotatably arranged in the cavity and is arranged perpendicular to the shaft 333. The circumferential surface of the rotating column 335 is provided with a plurality of inclined grooves 3351 around the circumference. The end of the slide bar 334 can be inserted into the inclined groove 3351. The depth of the inclined groove 3351 changes with the arc motion trajectory of the slide bar 334, gradually changing from shallow to deep and then gradually becoming shallow. The two ends of the two ends of the adjacent inclined grooves 3351 are located in the same vertical direction, so that after the slide bar 334 comes out of the previous inclined groove 3351, the next circle can enter the next inclined groove 3351. The placement plate 331 is rotatably arranged on the operating table 11. The rotation of the rotating column 335 can drive the placement plate 331 to rotate on the operating table 11.

[0042] By rotating the rotating shaft 333, the sliding rod 334 can be driven to move circumferentially. After the end of the sliding rod 334 is inserted into the inclined sliding groove 3351, it can drive the rotating column 335 to rotate in cooperation with the inclined sliding groove 3351, thereby driving the placement plate 331 to rotate on the operating table 11, so as to adjust the angle of the training model 31, so that the user can better sew the model.

[0043] In this embodiment, the rotating shaft 333 and the screw rod 222 are arranged in parallel, and the ends of the rotating shaft 333 and the screw rod 222 are both extended to the outside of the operating table 11 and connected with a knob. The side with the knob is located on the side close to the user, which makes it easier for the user to adjust the position of the microscope 21 and the angle of the training model 31 through the knob.

[0044] The placement assembly also includes a driving gear 336 and a driven gear 337. The driving gear 336 is fixedly sleeved on the outside of the rotating column 335. The placement plate 331 is rotatably arranged on the operating table 11 and connected to the driven gear 337. The driving gear 336 is meshed with the driven gear 337, and the diameter of the driving gear 336 is smaller than the diameter of the driven gear 337. The driven gear 337 and the placement plate 331 can be driven to rotate by rotating the rotating column 335 and the driving gear 336. The diameter of the driving gear 336 is small while the diameter of the driven gear 337 is large, so a small angle of rotation can be achieved, and the angle of the training model 31 can be fine-tuned.

[0045] In addition, the placement assembly also includes a pressing block 338 and a spring 339. One end of the pressing block 338 is sleeved on the rotating shaft 333, and the rotating shaft 333 is provided with a limit block 3331 that fits with both sides of the pressing block 338, and the other end is provided with a tooth groove that matches the driving gear 336, and the pressing block 338 is connected to the inner wall of the cavity through the spring 339. When it is necessary to adjust the angle of the training model 31, the rotating shaft 333 can be pulled outward first, and the pressing block 338 can be driven to move together through the limit block 3331, so that the tooth groove is disengaged from the driving gear 336, and the sliding rod 334 is also moved to a position where the rotating column 335 can be inserted. At this time, the rotating shaft 333 can be rotated, and the placement plate 331 can be driven to rotate through the rotating column 335. After the adjustment is completed, the rotating shaft 333 is released, and the tooth groove of the pressing block 338 is meshed with the driving gear 336 under the action of the spring 339, so that the placement plate 331 cannot rotate. In this embodiment, a fixing seat is provided in the cavity, and the pressing block 338 is connected to the fixing seat via a spring 339 .

[0046] Specifically, the fixing belt 332 is made of an elastic material, and is an elastic belt. One end of the fixing belt 332 is fixedly connected to the placement plate 331, and the other end is detachably connected to the placement plate 331 through a buckle. According to different surgeries, after the selected training model 31 is placed on the placement plate 331, both ends of the fixing belt 332 are wrapped around and connected to the placement plate 331 through the buckle, and the training model 31 can be pressed on the placement plate 331 under the action of elastic force.

[0047] The working principle of the above-mentioned microvascular suturing training platform is as follows: select the corresponding training model 31 according to the surgery to be simulated and place it on the placement plate 331, fix it with the fixing belt 332 and connect the liquid tube 321, and start the liquid pump 322 to simulate circulating blood. Rotate the screw 222 to drive the moving seat 221 to move, adjust the relative distance between the training model 31 and the microscope 21, then pull the rotating shaft 333 and rotate it, and drive the placement plate 331 to rotate with the cooperation of the sliding rod 334 and the rotating column 335 to adjust the relative angle between the training model 31 and the microscope 21. After the adjustment is completed, the user can observe the training model 31 through the microscope 21 and start simulating the training of vascular suturing.

[0048] The above-mentioned microvascular suturing training platform can be used to train microvascular suturing surgery, and different training models can be selected for simulation training. The position and angle of the model can be adjusted according to actual conditions, thereby achieving better simulation training effects.
