Description

Technical Field

[0001] This invention relates to the field of vascular surgery technology, specifically to an auxiliary detection device for vascular surgery. Background Technology

[0002] Vascular surgery is a branch of surgery that focuses on the prevention, diagnosis, and treatment of peripheral vascular diseases, excluding cerebrovascular and cardiac blood vessels. Since blood vessels are distributed throughout the human body except for hair, nails, and cornea, vascular surgery covers a wide range of conditions and can be broadly categorized into three types: arterial vascular diseases, venous vascular diseases, and other vascular diseases.

[0003] During patient treatment or nursing examinations, patients sometimes move their limbs due to pain or sensitivity. To ensure the accuracy of the examination and facilitate the work of medical staff, it is necessary to restrain the patient's limbs. Existing limb restraints mainly involve wrapping and fixing the patient's limbs tightly with straps or Velcro. This method of limb restraint is not easy to control the binding force. If the restraint is too loose, the patient's limb will move back and forth in multiple directions, affecting the examination; if the restraint is too tight, it will cause patient discomfort. Furthermore, it is difficult to accurately control the restraint, requiring repeated adjustments, which leads to complicated, time-consuming, and laborious operations, affecting the efficiency of medical staff in examining patients. Summary of the Invention

The rodless cavity of the outer tube is also connected to a second conduit. Both the first and second conduits are provided with one-way valves. The end of the second conduit away from the outer tube is connected to a nozzle. The nozzle is connected to the arc-shaped plate through a bracket.

[0011] Optionally, the binding assembly includes a connecting plate disposed at the bottom of the sliding seat, a drive motor fixedly mounted on the connecting plate, the output end of the drive motor passing through the connecting plate and connected to a screw, both ends of the screw being threadedly connected to sleeves, and the threads at both ends of the screw rotating in opposite directions, each sleeve being connected to one end of the binding strap.

[0012] Optionally, the sleeve is rotatably connected to a driving bevel gear via a bearing. The driving bevel gear is slidably disposed with the screw. The sleeve is also rotatably disposed with a driven bevel gear that meshes with the driving bevel gear via a bearing. A winding rod is fixed on the driven bevel gear. One end of the strap is connected to the winding rod. Two limiting rings are provided on the winding rod. The strap is wrapped around the winding rod and placed between the two limiting rings.

[0013] Optionally, a fixing plate is fixedly connected to the surface of the L-shaped connecting plate, and a limiting rod is fixedly connected to the surface of the fixing plate. The limiting rod passes through the moving frame and is slidably connected to it.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: I. This invention places the patient's limbs in a limb binding mechanism, controls the binding component to tighten the binding straps, and automatically binds the patient's limbs. Pressure sensors on the binding straps detect the pressure exerted on the limbs, ensuring sufficient binding force while quickly pressing and fixing the patient's limbs. This reduces the workload of medical staff, improves the efficiency and effectiveness of patient fixation, and ultimately enhances the efficiency of medical staff's examinations.

[0017] Second, this invention allows the arc-shaped seat to slide in the groove, enabling the limb binding mechanism to be adjusted in position on the operating table according to the patient's height. This allows the limb binding mechanism to effectively fix the hands and legs. Furthermore, the arc-shaped seat can rotate relative to the sliding seat, causing the arc-shaped seat to drive the binding components and straps to twist. This makes the axis of the arc-shaped seat parallel to the limb, making the limb binding mechanism suitable for patients of different body types and highly adaptable. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0021] Please see Figures 1 to 8 The present invention provides a technical solution: an auxiliary detection device for vascular surgery, including an operating table 1, a support base 101 at the bottom of the operating table 1, a headrest 102 at the top of the operating table 1, and multiple sets of limb binding mechanisms 2 with identical structures on the operating table 1. Each limb binding mechanism 2 includes a groove 103 opened on the operating table 1, a support plate 3 disposed in the groove 103, an arc-shaped seat 4 disposed at the groove 103, an elastic connector 5 disposed on the arc-shaped seat 4, a binding strap 6 disposed at the end of the elastic connector 5 away from the arc-shaped seat 4, and a binding component for driving the binding strap 6 to perform binding action on the arc-shaped seat 4.

[0022] Furthermore, the limb binding mechanism 2 is provided with four sets, including two sets of limb binding mechanisms 2 for binding the hands and two sets of limb binding mechanisms 2 for binding the feet, and the distance between the two sets of hand limb binding mechanisms 2 is greater than the distance between the two sets of foot limb binding mechanisms 2.

[0023] More specifically, in this embodiment, when in use, the patient lies flat on the operating table 1, with the patient's hands and feet placed in the groove 103 and supported by the support plate 3. The headrest 102 can improve the patient's comfort during the examination. Then, the patient's ankles and wrists are fixed by the limb binding mechanism 2. The binding component drives the binding strap 6 to automatically bind the patient, ensuring the binding force on the patient while quickly pressing and fixing the patient's limbs, reducing the workload of medical staff, improving the fixation efficiency and fixation effect on the patient, and thus improving the examination efficiency of medical staff.

[0024] Example 2, based on the above examples, Furthermore, the arc-shaped seat 4 includes an arc-shaped plate 401 and a sliding seat 402 connected to the end of the arc-shaped plate 401. The operating table 1 is provided with a sliding groove 104 that cooperates with the sliding seat 402.

[0025] More specifically, in this embodiment, the arc-shaped seat 4 can slide within the sliding groove 104 via the sliding seat 402 to adjust the position of the arc-shaped seat 4 and the strap 6, so that the limb binding mechanism 2 can effectively fix the hands and legs, and is suitable for patients of different heights.

[0026] Example 3, based on the above examples, Furthermore, a pressure sensor 602 is provided on the bottom side of the strap 6, a reinforcing plate 601 is provided on the strap 6, and ear plates 7 are provided on both the reinforcing plate 601 and the arc plate 401. The two ends of the elastic connector 5 are connected to the ear plates 7 by pins.

[0027] Furthermore, the elastic connector 5 includes an outer tube 501 movably connected to the arc plate 401, a piston plate 502 slidably connected inside the outer tube 501, an inner rod 503 movably connected to the reinforcing plate 601 on the piston plate 502, a first elastic element 504 sleeved on the inner rod 503, and the two ends of the first elastic element 504 being connected to the piston plate 502 and the inner wall of the outer tube 501, respectively.

[0028] More specifically, in this embodiment, when in use, the strap 6 is driven by the binding component to automatically bind the patient's limb. When the strap 6 comes into contact with the limb, the binding force can be detected by the pressure sensor 602. At the same time, when the strap 6 is binding, the elastic connector 5 automatically swings and is stretched, and the inner rod 503 moves out of the outer tube 501. After the strap 6 is no longer under force, the strap 6 will automatically reset under the pull of the first elastic element 504, in preparation for the subsequent fixation of the patient's limb.

[0029] Example 4, based on the above examples, Furthermore, a pneumatic cavity 12 is provided on the sliding seat 402, and an air guide pipe 13 is connected between the pneumatic cavity 12 and the rod cavity of the outer tube 501. A piston block 121 is slidably connected in the pneumatic cavity 12, and a second elastic element 122 is provided between the piston block 121 and the inner wall of the pneumatic cavity 12. A positioning rod 123 is provided on the side of the piston block 121 away from the second elastic element 122. A plurality of positioning holes 1041 are provided in the sliding groove 104 at equal intervals, and the positioning rod 123 is movably disposed in the positioning hole 1041.

[0030] More specifically, in this embodiment, when the strap 6 is used to bind the limbs, the elastic connector 5 will be stretched, and the air in the rod chamber of the outer tube 501 will enter the pneumatic chamber 12 through the air guide tube 13. The piston block 121 will be moved by force and drive the positioning rod 123 to move out of the sliding seat 402, so that the positioning rod 123 is inserted into the positioning hole 1041 at the corresponding position of the sliding seat 402 at this time, thereby restricting the limb binding mechanism 2 and preventing the limb binding mechanism 2 from moving to the designated position through the sliding seat 402 and then shaking randomly during limb binding, which would affect the fixation effect on the patient's limbs and thus affect the efficiency and effect of medical personnel in testing patients.

[0031] Example 5, based on the above examples, Furthermore, the binding assembly includes a connecting plate 8 disposed at the bottom of the sliding seat 402. A drive motor 9 is fixedly mounted on the connecting plate 8. The output end of the drive motor 9 passes through the connecting plate 8 and is connected to a screw 801. Both ends of the screw 801 are threadedly connected to sleeves 802, and the threads at both ends of the screw 801 rotate in opposite directions. Each sleeve 802 is connected to one end of the binding strap 6.

[0032] Furthermore, the sleeve 802 is rotatably connected to the driving bevel gear 803 via a bearing. The driving bevel gear 803 is slidably disposed with the screw 801. The sleeve 802 is also rotatably disposed with the driven bevel gear 10, which meshes with the driving bevel gear 803, via a bearing. A winding rod 11 is fixed on the driven bevel gear 10. One end of the strap 6 is connected to the winding rod 11. Two limiting rings 111 are provided on the winding rod 11. The strap 6 is wrapped around the winding rod 11 and placed between the two limiting rings 111. A guide bar 8031 ​​is provided on the driving bevel gear 803. A guide groove 8011 that cooperates with the guide bar 8031 ​​is opened on the screw 801. The guide bar 8031 ​​is slidably connected in the guide groove 8011.

[0033] More specifically, in this embodiment, by controlling the operation of the drive motor 9, the output end of the drive motor 9 drives the screw 801 to rotate on the connecting plate 8. Since the threads at both ends of the screw 801 rotate in opposite directions, the sleeves 802 at both ends of the screw 801 are brought closer together. It should be noted that a limit rod should be provided on the connecting plate 8 to restrict the movement direction of the sleeves 802. This is common knowledge to those skilled in the art and will not be elaborated here. When the two sleeves 802 are brought closer together, they will drive the two ends of the strap 6 to move towards the sides of the limb. During this process, the sleeves 802 drive the active bevel gear 803 to move laterally, and the screw 801 is driven by the guide bar 8031. The active bevel gear 803 moves laterally and rotates simultaneously, thereby engaging with the driven bevel gear 10 on the other side of the sleeve 802. This drives the winding rod 11 to rotate, and the winding rod 11 winds up the strap 6, causing the strap 6 to move downward and closer to the upper side of the limb. This tightens the strap 6, automatically binding the patient's limb. A pressure sensor 602 is installed on the strap 6 to detect the pressure of the strap 6 on the limb, ensuring the binding force on the patient while quickly pressing and fixing the patient's limbs. The limiting ring 111 on the outer side of the winding rod 11 can limit the winding of the strap 6, ensuring the winding effect of the strap 6.

[0034] Example 6, based on the above examples, Furthermore, the two ends of the arc plate 401 are respectively provided with a first rotating rod 14 and a second rotating rod 15. The first rotating rod 14 is rotatably connected to one of the sliding seats 402, and the second rotating rod 15 is movably connected to the other sliding seat 402. The bottoms of the first rotating rod 14 and the second rotating rod 15 are fixedly connected to the connecting plate 8. The first rotating rod 14 is provided with through holes 141 that are evenly distributed around the circumference, and the positioning rod 123 is movably connected in the through holes 141.

[0035] More specifically, in this embodiment, when the limb binding mechanism 2 is moved within the sliding groove 104 via the sliding seat 402, the position of the limb binding mechanism 2 is made suitable for patients of different heights. However, in actual use, due to differences in patient body size and obesity, the distance between the two sets of foot binding mechanisms 2 and the distance between the hand binding mechanisms 2 are not suitable. At this time, the arc plate 401 can be rotated so that the arc plate 401 rotates around the first rotating rod 14, and the second rotating rod 15 connected to the other end of the arc plate 401 rotates accordingly, thereby making the first rotating rod 14 rotate around the first rotating rod 14. The connecting plate 8 connected to the bottom of the second rotating rod 15 rotates, finely adjusting the binding direction of the binding assembly and the binding strap 6, so that the axis of the arc-shaped seat 4 is parallel to the limb, making the limb binding mechanism 2 suitable for patients of different body types, with strong applicability. When binding the patient's limb, the elastic connecting piece 5 is stretched, which increases the air in the pneumatic chamber 12. The piston block 121 is forced to drive the positioning rod 123 to move, so that the positioning rod 123 passes through the through hole 141 of the first rotating rod 14 and extends to the positioning hole 1041 in the sliding groove 104, thereby restricting the position and binding direction of the limb binding mechanism 2.

[0036] Example 7, based on the above examples, Furthermore, a rubber pad 18 is provided on the strap 6, and a cavity is provided inside the rubber pad 18. The rod chamber of the outer tube 501 is also connected to the cavity through an air tube. A liquid storage shell 16 is provided at the bottom of the arc plate 401. A first conduit 161 is connected between the liquid storage shell 16 and the rodless chamber of the outer tube 501. A second conduit 162 is also connected to the rodless chamber of the outer tube 501. A one-way valve is provided on both the first conduit 161 and the second conduit 162. A nozzle 17 is connected to the end of the second conduit 162 away from the outer tube 501. The nozzle 17 is connected to the arc plate 401 through a bracket.

[0037] More specifically, in this embodiment, when the strap 6 binds the limb, the elastic connector 5 is stretched. Some air in the rod cavity of the outer tube 501 enters the cavity of the rubber pad 18 through the air tube. The rubber pad 18 expands due to the gas filling. The expanded rubber pad 18 can effectively fill the gap between the strap 6 and the patient's limb, avoiding poor binding effect and causing the patient's limb to shake. On the other hand, it can also increase the patient's comfort during the test. When the elastic connector 5 is stretched, the movement of the piston plate 502 in the outer tube 501 will draw disinfectant alcohol from the reservoir shell 16 through the first conduit 161. When the strap 6 is released from binding the patient's limb, the elastic connector 5 returns to its original position, and the piston plate 502 sprays the previously drawn disinfectant alcohol onto the rubber pad 18 through the nozzle 17 to disinfect the rubber pad 18 to a certain extent, avoiding cross-infection when the rubber pad 18 comes into contact with other patients, and ensuring the hygiene and safety of the device.

[0038] Working principle: The patient lies flat on the operating table 1, with the patient's hands and feet placed in the groove 103 and supported by the support plate 3. The headrest 102 can improve the patient's comfort during the examination. The position of the limb binding mechanism 2 is adjusted according to the patient's height and weight. When in use, the arc-shaped seat 4 can slide in the sliding groove 104 through the sliding seat 402. The position of the arc-shaped seat 4 and the binding strap 6 can be adjusted so that the arc-shaped seat 4 and the binding strap 6 are moved to the wrist and ankle. Then, according to the patient's body shape, the arc-shaped plate 401 is rotated, so that the arc-shaped plate 401 rotates around the first rotating rod 14. The second rotating rod 15 connected to the other end of the arc-shaped plate 401 rotates accordingly, so that the connecting plate 8 connected to the bottom of the first rotating rod 14 and the second rotating rod 15 rotates. The binding direction of the binding assembly and the binding strap 6 is finely adjusted so that the axis of the arc-shaped seat 4 is parallel to the limb, so that the limb binding mechanism 2 can be used by patients of different body shapes. By controlling the operation of the drive motor 9, the output end of the drive motor 9 drives the screw 801 to rotate on the connecting plate 8. Since the threads at both ends of the screw 801 rotate in opposite directions, the sleeves 802 at both ends of the screw 801 are relatively close. When the two sleeves 802 are relatively close, they will drive the two ends of the strap 6 to move closer to the sides of the limb. During this process, the sleeves 802 drive the active bevel gear 803 to move laterally. The screw 801 drives the active bevel gear 803 to move laterally and rotate through the guide bar 8031. This causes the active bevel gear 803 to mesh with the driven bevel gear 10 on the other side of the sleeve 802. The driven bevel gear 10 drives the winding rod 11 to rotate. The winding rod 11 winds up the strap 6, causing the strap 6 to move down and move closer to the upper side of the limb. This causes the binding assembly to wind up and tighten the strap 6. The strap 6 automatically binds the patient's limb. The strap 6 is equipped with a pressure sensor 602 to detect the pressure of the strap 6 on the limb, ensuring the binding force on the patient while quickly pressing and fixing the patient's limbs. When the straps 6 bind the limbs, the elastic connector 5 is stretched, and the air in the rod chamber of the outer tube 501 enters the pneumatic chamber 12 through the air guide tube 13. The piston block 121 moves under force and drives the positioning rod 123 to move out of the sliding seat 402, so that the positioning rod 123 passes through the through hole 141 of the first rotating rod 14 and extends to the positioning hole 1041 in the sliding groove 104. This restricts the position and binding direction of the limb binding mechanism 2, and prevents the limb binding mechanism 2 from moving to the designated position through the sliding seat 402 and then shaking randomly during limb binding, which would affect the fixation effect on the patient's limb, thereby ensuring the efficiency and effect of the medical staff's examination of the patient.
