Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more specifically, to a unilateral restraint device for patients on a DSA interventional operating table. Background Art

[0002] A unilateral restraint device for patients on a DSA interventional operating table is a medical device used to assist in digital subtraction angiography (DSA) interventional surgery. Its main function is to fix the unilateral limb or body part of the patient during the operation to ensure the stable position of the patient and avoid affecting the surgical operation and imaging quality due to movement.

[0003] Due to individual differences among patients, their heights, weights, and head circumferences are different, which leads to the inability of the standardized operating table and the standard lashing structure to fit all patients. As a result, it cannot be guaranteed whether incorrect lashing during the operation will cause surgical operation errors by doctors. Summary of the Invention

[0004] Aiming at the problem in the prior art that due to individual differences among patients, their heights, weights, and head circumferences are different, which leads to the inability of the standardized operating table and the standard lashing structure to fit all patients, the purpose of the present invention is to provide a unilateral restraint device for patients on a DSA interventional operating table.

[0005] To solve the above problems, the present invention adopts the following technical solutions:

[0006] A unilateral restraint device for patients on a DSA interventional operating table includes a head fixing mechanism provided at the head of the operating table and two adjustable foot fixing components provided in the leg placement area of the operating table. It is characterized in that two groups of arm fixing frames are installed by bolts above the operating table at the position of the human arm, and a torso fixing component for lashing the human torso is provided between the two groups of arm fixing frames;

[0007] The bottom end of the operating table is connected by bolts to a motor chamber, two groups of locking components are placed on the side of the motor chamber, and two sliding grooves are provided at the leg end of the operating table;

[0008] A first locking warning light is fixedly connected to the edge of the operating table, and a second locking warning light is provided at the position of the human head and shoulder of the operating table;

[0009] The head fixing mechanism includes a headrest frame rotatably connected to the operating table;

[0010] It further includes a connecting plate fixedly connected to the outer surface of the headrest frame; both sides of the connecting plate are connected with second side baffles through buckles; an inflatable neck support belt is arranged between the two groups of second side baffle assemblies.

[0011] Optionally, the head fixing mechanism includes an inflation nozzle for inflating the inflatable neck support belt. Through slots are provided through both sides of the second side baffle, and a semi-circular filling belt connection slot is arranged on one side of the through slot close to the connecting plate.

[0012] Optionally, the head fixing mechanism further includes two lashing side guard plates fixedly connected to the outer surface of the other end of the headrest frame;

[0013] Two insertion slots are fixedly connected to the edge of the headrest frame, and a mounting plate is fixedly connected at the middle position between the two insertion slots. A regulating frame that can swing along the axis is fixedly connected to the side of the mounting plate away from the headrest frame, and a rotating shaft is fixedly connected to the side of the regulating frame away from the mounting plate.

[0014] Optionally, the adjustable foot fixing assembly includes two platform plates fixedly connected in the sliding groove. Two groups of slide rails are arranged above the two platform plates. Two groups of sliders are slidably connected above the two slide rails. A connecting platform is fixedly connected above the two groups of sliders. A fixed disk is fixedly arranged above the connecting platform. A placing block is fixedly connected above the fixed piece. A heel placing position for placing the heel area of the human body is arranged at the top end of the placing block.

[0015] Optionally, the adjustable foot fixing assembly further includes a first side baffle fixedly arranged on the side of the platform plate between the two groups of slide rails. Sliding limit slots are reserved on both sides of the second side baffle. A locking handle is arranged on the side of the second side baffle away from the connecting platform;

[0016] Support rods are fixedly connected to the four sides of the upper surface of the platform plate, and a support bottom plate is fixedly connected to the end of the support rod away from the platform plate.

[0017] Optionally, the locking component includes a housing fixedly connected to the lower surface of the operating bed. A sliding push frame is arranged at the edge of the housing. A plugging rod is installed above the sliding push frame, and a trigger head is fixedly arranged at the pushing end of the plugging rod.

[0018] Optionally, an insertion interface is arranged at one end of the operating bed where the head fixing mechanism is located. The operating bed and the head fixing mechanism form a rotating connection structure through the insertion interface and the rotating shaft, and the operating bed and the head fixing mechanism are formed through the insertion slot and the plugging rod.

[0019] Optionally, the motor chamber includes a placement box fixedly connected to the middle bottom of the operating bed. A fixing frame is fixedly connected inside the placement box, and a servo motor is placed inside the fixing frame. A switch is fixedly connected to the bottom of the placement box.

[0020] Optionally, winding handles are fixedly connected to the edges of the operating bed where the arm fixing frames are located. Two sets of tightening grooves are reserved at the top of the operating bed, and a strap conveying groove is arranged at the top of the arm fixing frame.

[0021] Optionally, two tightening grooves are arranged at the trunk end of the operating bed. The two sets of tightening grooves are symmetrically arranged along the head fixing mechanism. The trunk fixing component includes two elastic bands. Both ends of the two elastic bands pass through the tightening grooves, and the leading ends of the elastic bands are fixedly connected to the output end of the servo motor.

[0022] The technical solution provided by the present invention has at least the following beneficial effects compared with the prior art:

[0023] In the above solution, for the structural errors, the first locking warning light and the second locking warning light are used to confirm the binding positions of the patients on the operating bed respectively. The specific state of the binding of the operating bed can be confirmed by whether there is obvious light flashing. After adjusting the operating bed based on the patient's body, the corresponding head fixing mechanism and the adjustable foot fixing component of the operating bed are confirmed. After the adjustment is completed, observing the brightness of the light can confirm whether the adjustment meets the operation standards, so as to reduce the errors caused by the non-standard fixation of the operating bed during the surgical operation.

[0024] Among them, for patients with different standardized head circumferences that do not meet the standard range, the head fixing mechanism is flipped, and the filling fixation method is adopted. The patient's head is placed in the space between the connecting plate and the two side baffles. At this time, air is blown into the air inlet nozzle, so that the air-filled neck guard is filled with air and expands. The expanded air-filled neck guard slowly becomes larger. The nurse adjusts the position of the air-filled neck guard to fit the patient's face, so as to adjust the air-filled neck guard to support the patient's face and shoulders. At the same time, the nurse observes the fitting position of the air-filled neck guard and the patient's neck to avoid compressing the artery. After confirming that the patient's ear is in the ear slot, the filling belt on the filling belt connecting groove is gradually tightened to make the filling belt contact the patient's head top, and the head fixation of special patients is completed.

[0025] Based on the height problems of different patients, for the standardized operating table, although adjustable straps are used to fix the patients, to ensure the blood circulation of the patients, when tying the straps, it is necessary to ensure that the tying position will not affect the patients. However, due to the unconscious twitching of the patients, the reflexive limb movement caused will make the patients drive the elastic straps to twitch. The twitching caused by patients who are too tall or too short will make the straps of the tied patients appear in different positions on the operating table, and the position of the corresponding straps will indirectly affect the operation process. Therefore, when the patient lies flat above the operating table, the nurse loosens the locking handle, so that the adjustable foot fixing component slides along the sliding groove and moves to the heel of the patient. At this time, when facing a patient who is too tall, loosen the fixed end of the adjustable foot fixing component and the operating table, so that when the adjustable foot fixing component is in a sliding state, the force exerted by the leg of the patient who is too tall on the foot is released. Through the sliding of the adjustable foot fixing component, when the leg of the patient who is too tall twitches, the force of the leg twitching acts on the adjustable foot fixing component, so that the foot position of the patient who is too tall cannot stretch along with the twitching, directly reducing the movement of the patient caused by the unconscious twitching during the operation. For standard or too short patients, lock the adjustable foot fixing component, so that when the patient twitches unconsciously, the deviation caused by the patient's twitching is reduced through the restriction of the heel by the adjustable foot fixing component.

[0052] As Figures 1 to 8 shown, an embodiment of the present invention provides a unilateral restraint device for a patient on a DSA interventional operating table 1, including a head fixing mechanism 2 provided at the head of the operating table 1, and two adjustable foot fixing assemblies 5 provided in the area where the legs of the operating table 1 are placed. Two groups of arm fixing frames 3 are installed at the position of the human arm above the operating table 1 through bolts, and a trunk fixing assembly 4 for binding the human trunk is provided between the two groups of arm fixing frames 3.

[0053] The bottom end of the operating table 1 is connected to a motor chamber 8 through bolts, and two groups of locking assemblies 11 are placed on the side of the motor chamber 8, and two sliding grooves 101 are provided at the leg end of the operating table 1.

[0054] A first locking warning lamp 7 is fixedly connected to the edge of the operating table 1, and a second locking warning lamp 9 is provided at the position of the human head and shoulder of the operating table 1; the two warning lamps are connected in parallel and connected to the power supply of the control system of the operating table, and are controlled in zones through their respective independent sensor signal circuits. Each lamp detects the binding state of a specific area to confirm the binding situation. And for structural mistakes, the binding positions of the patient on the operating table 1 are confirmed through the first locking warning lamp 7 and the second locking warning lamp 9 respectively. Among them, the first locking warning lamp 7 corresponds to the binding position of the patient on the operating table. Through the pressure sensing probe on the pressure sensor installed on the center of the strap sheath on the strap, when the patient is not correctly bound in this area, the sensor on the strap cannot be triggered at this time, and the first locking warning lamp 7 starts to flash to inform the binding situation. The second locking warning lamp 9 corresponds to the chest position. At this time, the pressure sensing probe on the elastic locking strap 401, if the chest is not fixed in place, the pressure sensor signal is abnormal, and the lamp 9 flashes. Since its lamp structure and pressure sensor structure are both prior arts, they will not be repeated here. The specific state of the binding of the operating table 1 can be confirmed by whether there is obvious lamp flashing. After adjusting the operating table 1 based on the patient's body, confirm the corresponding head fixing mechanism 2 and adjustable foot fixing assembly 5 of the operating table 1. After the adjustment is completed, observe the brightness of the lamp to confirm whether the adjustment meets the operation standard, so as to reduce mistakes caused by non-standard fixing of the operating table 1 during the operation.

[0055] As Figure 2 and Figure 6 shown, the head fixing mechanism 2 includes a headrest frame 201 rotatably connected to the operating table 1. It further includes a connecting plate 23 fixedly connected to the outer surface of the headrest frame 201; both sides of the connecting plate 23 are connected with first side baffles 24 through buckles; an inflatable neck support belt 27 is arranged between the two groups of first side baffle assemblies.

[0056] As Figure 6 shown, the head fixing mechanism 2 includes an inflation nozzle 28 for inflating the inflatable neck support belt 27. Ear slots 26 are penetrated through both sides of the first side baffle 24, and a semi-circular filling belt connection groove 25 is arranged on one side of the ear slot 26 close to the connecting plate 23. Among them, there are obvious differences in the age and body shape of the patients targeted by the operation, which leads to that although the fixing points of the standardized operating table 1 for patients meet most patients, there are still some patients who cannot use the standardized lashing points, such as patients with large heads, small heads, and elderly patients. Therefore, the head fixing mechanism 2 is adopted. Two different structures are set on the front and back of the head fixing mechanism 2 for the heads of two different patients. The head fixing mechanism 2 is flipped (rotated 180°) to adapt to the type of the patient, so as to better fix the patient and reduce the intraoperative jitter problem caused by the non-standard lashing posture of the patient.

[0057] Among them, for patients with a head circumference different from the standard and not within the standard range, the head fixing mechanism 2 is flipped and a filling type fixing method is adopted. The head of the patient is placed in the space between the connecting plate 23 and the two first side baffles 24. At this time, air is blown into the inflation nozzle 28, so that the air is filled in the inflatable neck support belt 27 and expands. The expanded inflatable neck support belt 27 slowly becomes larger. The nurse adjusts the position of the inflatable neck support belt 27 and fits it with the face of the patient, so as to adjust the inflatable neck support belt 27 to support the face and shoulders of the patient. At the same time, the nurse observes the fitting position of the inflatable neck support belt 27 with the neck of the patient to avoid compressing the artery. After confirming that the ear of the patient is in the ear slot 26, the filling belt on the filling belt connection groove 25 is gradually tightened so that the filling belt contacts the top of the patient's head, and the head fixation of special patients is completed.

[0058] As Figure 5 shown, the head fixing mechanism 2 further includes two lashing side guard plates 202 fixedly connected to the outer surface of the other end of the headrest frame 201. For patients with a standard head circumference, standard lashing side guard plates 202 are adopted, and the head of the patient is fixed through a connecting strap to complete the head circumference fixation of ordinary patients.

[0059] Again, as Figure 4 and Figure 5As shown, two plug slots 203 are fixedly connected to the edge of the headrest frame 201, and a mounting plate 204 is fixedly connected at the middle position between the two plug slots 203. A rotatable adjusting frame 205 is fixedly connected to the side of the mounting plate 204 away from the headrest frame 201. A rotating shaft 206 is fixedly connected to the side of the adjusting frame 205 away from the mounting plate 204. When the headrest frame 201 needs to be adjusted, a limiting and rotating structure is used. When rotation is required, the locking component 11 releases the restriction between the headrest frame 201 and the operating table 1, and the rotating shaft 206 inserted into the operating table 1 rotates along the horizontal direction of the operating table 1 (rotating 180°) to complete the adjustment of the position of the headrest frame 201. After the position adjustment of the headrest frame 201 is completed, the locking component 11 fixes the headrest frame 201 again, and while fixing, observe the flashing condition of the second locking warning light 9 to confirm whether the locking is completed.

[0060] As Figure 4 and Figure 7 shown, the adjustable foot fixing assembly 5 includes two platform plates 15 fixedly connected in the sliding groove 101, and two groups of slide rails 18 are arranged above the two platform plates 15. Two groups of sliders 19 are slidably connected above the two slide rails 18. A connecting table 20 is fixedly connected above the two groups of sliders 19. A fixed disk 21 is fixedly arranged above the connecting table 20. A placing block 22 is fixedly connected above the fixing piece. A heel placing position 221 for placing the heel area of the human body is arranged at the top end of the placing block 22.

[0061] Again, as Figure 4As shown, the adjustable foot fixing assembly 5 further includes a platform plate 15. A second side baffle 16 is fixedly arranged on the side of two sets of the slide rails 18. A sliding limit groove 17 is reserved on the second side baffle 16. A locking handle 6 is arranged in the sliding limit groove 17 of the second side baffle 16. More specifically, the handle of the locking handle 6 includes a locking rod 601 and a handle 602. One end of the locking rod is a smooth rod and the other end is a threaded rod. An external thread is arranged on the outer surface of the threaded rod. The smooth rod is inserted into the sliding limit groove 17 and the end of the smooth rod is connected to a connecting platform 20. The outer side surface of the connecting platform 20 is attached to the side surface of the second side baffle 16. An internal thread is arranged on the handle 602. The internal thread of the handle 602 is screwed with the external thread of the locking rod 601. By rotating the handle 602, the end of the handle 602, the second side baffle 16 and the connecting platform 20 can be clamped to limit the movement of the connecting platform 20. Four sides of the platform plate 15 are fixedly connected with support rods 14, and one end of the support rod 14 far away from the platform plate 15 is fixedly connected with a support bottom plate 13. Due to the height problems of different patients, for the standardized operating bed 1, although adjustable binding belts are used to fix the patients, to ensure the blood circulation of the patients, when binding, it is necessary to ensure that the binding position will not affect the patients. However, due to the unconscious twitching of the patients, the reflex limb movement caused will make the patients drive the elastic binding belts to twitch. The twitching caused by too tall or too short patients will make the binding belts of the bound patients present at different positions on the operating bed 1, and the corresponding positions of the binding belts will indirectly affect the operation process of the operation. Therefore, when the patient lies flat above the operating bed 1, the nurse loosens the locking handle 6 to make the adjustable foot fixing assembly 5 slide along the sliding groove 101 and move to the heel of the patient. At this time, for a too tall patient, when loosening the fixed end of the adjustable foot fixing assembly 5 and the operating bed 1 to make the adjustable foot fixing assembly 5 in a sliding state, the force exerted by the leg of the too tall patient on the foot can be released. By the sliding of the adjustable foot fixing assembly 5, the leg twitching of the too tall patient can be reduced, and the leg twitching is applied to the adjustable foot fixing assembly 5 to directly reduce the unconscious twitching of the patient during the operation. For a standard or too short patient, the adjustable foot fixing assembly 5 is locked so that when the patient twitches unconsciously, the deviation caused by the twitching of the patient can be reduced through the restriction of the heel by the adjustable foot fixing assembly 5.

[0062] As Figure 8 and Figure 9As shown, the locking assembly 11 includes a housing 33 fixedly connected to the lower surface of the operating table 1. A sliding push frame 36 is provided at the edge of the housing 33. Above the sliding push frame 36, a plug rod 35 is installed, and the plug rod 35 can move within the operating table 1. Specifically, a plug rod installation cavity is provided inside the operating table 1, and the plug rod 35 is installed in the plug rod installation cavity. A trigger head 351 is fixedly provided at the pushing end of the plug rod 35. The locking end of the locking handle 6 of the adjustable foot fixing assembly 5 is also provided with a trigger head 351 for confirming whether the adjustable foot fixing assembly 5 is in a locked state. When installing the head fixing mechanism 2, the sliding push frame 36 has a push-pull structure. The sliding push frame 36 is fixed by a slide rail 361, a connecting frame 362, and a locking handle 363. The connecting frame 361 is slidably connected to the slide rail 362, the slide rail 362 is installed on the housing 33, and the connecting frame 361 is connected to the plug rod 35. The locking handle 363 includes a pushing member 3631. The pushing member 3631 is slidably installed on the slide rail 362. One end of the pushing member 3631 is connected to the connecting frame 362. An internal thread through hole is provided on the pushing member 3631, and an external thread portion is provided on the handle 3632. The external thread of the external thread portion of the handle 3632 is screwed with the internal thread of the internal thread through hole. When the connecting frame 361 is pushed along the slide rail 362 by the locking handle 363, and the plug rod 35 connected to the connecting frame 362 is driven to move horizontally, and by rotating the handle, the external thread portion of the handle 3632 abuts against the slide rail 362 to fix the connecting frame 362 and the slide rail 361, thereby fixing the position of the plug rod 35. The plug rod 35 is inserted into the plug slot 203 provided in the head fixing mechanism 2 to complete the fixation. After the locking handle 363 of the sliding push frame 36 completes the insertion, it is rotated to lock the position of the plug rod 35.

[0063] As shown in Figure 8 As shown, at one end of the operating table 1 where the head fixing mechanism 2 is located, there is an insertion port 34. The rotating shaft 206 is inserted into the insertion port 34, and the plug rod 35 is inserted into the plug slot 203 of the operating table 1 and the head fixing mechanism 2.

[0064] Again, as shown in Figure 7 As shown, the motor chamber 8 includes a placement box 29 fixedly connected to the middle bottom of the operating table 1. A fixing frame 30 is fixedly connected inside the placement box 29, and a servo motor 31 is placed inside the fixing frame 30. The bottom of the placement box 29 is fixedly connected with a switch 32.

[0065] As shown in Figure 1 and Figure 3As shown, at the edge of the operating table 1, the arm fixing frame 3 is fixedly connected with a winding handle 10. The winding handle 10 is composed of a handle and a winding rod. The plate body on the handle is connected to the operating table. At this time, the strap passes through the strap conveying groove 12 on the arm fixing frame 3 and is connected to the winding rod. By rotating the handle, the winding rod is driven to rotate, so that the strap on the winding rod is tightened, thereby restricting the patient's arm inside the arm fixing frame 3. And two tightening grooves 102 are reserved at the top of the operating table 1, and a strap conveying groove 12 is arranged at the top of the arm fixing frame 3. The strap for tying the patient's hand is fixed in contact with the operating table 1 at the bottom of the groove of the arm fixing frame 3, and then the strap passes through the groove at the top of the arm fixing frame 3 and enters. After the patient's arm is placed inside the arm fixing frame 3, by rotating the winding handle 10, the strap connected to the winding handle 10 is continuously tightened, so that the patient's arm is restricted inside the arm fixing frame 3, thereby limiting the patient's arm.

[0066] Two tightening grooves 102 are arranged at the trunk end of the operating table 1. The two groups of tightening grooves 102 are symmetrically arranged along the head fixing mechanism 2. The trunk fixing assembly 4 includes two elastic bands 401. Both ends of the two elastic bands 401 pass through the tightening grooves 102. The leading end of the elastic band 401 is fixedly connected to the output end of the servo motor 31. For the patient's trunk, the servo motor 31 is used to assist in tightening to complete the fixation of the patient's trunk. The servo motor 31 rotates continuously to wind up the elastic band 401 and complete the tightening of the elastic band 401. More specifically, a winding roller is installed on the output shaft of the servo motor 31, and the elastic band 401 is wound around the winding roller. More specifically, the tightening groove 102 is a through groove, so that the elastic band 401 can be installed on the winding roller of the servo motor 31 after passing through the tightening groove 102.

[0067] The working process of the technical solution provided by the present invention is as follows:

[0068] First, for the structural errors, the first locking warning lamp 7 and the second locking warning lamp 9 are used to confirm the binding positions of the patients on the operating table 1 respectively. The specific state of the binding of the operating table 1 can be confirmed by whether there is obvious light flashing. After adjusting the operating table 1 based on the patient's body, the corresponding head fixing mechanism 2 and the adjustable foot fixing assembly 5 of the operating table 1 are confirmed. After the adjustment is completed, observing the brightness of the lights can confirm whether the adjustment meets the operation standards, so as to reduce the errors caused by the non-standard fixation of the operating table 1 during the surgical operation.

[0069] Among them, for patients with a differentiated standardized head circumference and a head circumference that does not meet the standard range, the head fixing mechanism 2 is flipped, and a filling fixing method is adopted. The patient's head is placed in the space between the connecting plate 23 and the two first side baffles 24. At this time, air is blown into the air nozzle 28, so that the air in the inflatable neck guard 27 is filled and expands. The expanded inflatable neck guard 27 slowly becomes larger. The nurse adjusts the position of the inflatable neck guard 27 to fit the patient's face, so as to adjust the support of the inflatable neck guard 27 on the patient's face and shoulders. At the same time, the nurse observes the fitting position of the inflatable neck guard 27 and the patient's neck to avoid compressing the artery. After confirming that the patient's ear is placed in the ear slot 26, the filling belt on the filling belt connection groove 25 is gradually tightened so that the filling belt contacts the patient's head top, and the head fixation of special patients is completed.

[0070] Regarding the height problems of different patients, for the standardized operating bed 1, although adjustable lashing straps are used to fix the patients, to ensure the blood circulation of the patients, during lashing, it is necessary to ensure that the lashing position will not affect the patients. However, due to the unconscious twitching of the patients, the reflex limb movement caused will make the patients drive the elastic lashing straps to twitch. The twitching caused by too tall or too short patients will make the lashing straps of the lashed patients present at different positions on the operating bed 1, and the corresponding positions of the lashing straps will indirectly affect the operation process of the surgery. Therefore, when the patient lies flat above the operating bed 1, the nurse loosens the locking handle 6, so that the adjustable foot fixing assembly 5 slides along the sliding groove 101 and moves to the patient's heel. At this time, when facing a too tall patient, the fixed end of the adjustable foot fixing assembly 5 and the operating bed 1 is loosened. When the adjustable foot fixing assembly 5 is in a sliding state, the force exerted by the leg of the too tall patient on the foot is released. By sliding the adjustable foot fixing assembly 5, the leg twitching of the too tall patient is reduced, and the leg twitching is applied to the adjustable foot fixing assembly 5, directly reducing the unconscious twitching of the patient during the operation. For standard or too short patients, the adjustable foot fixing assembly 5 is locked, so that when the patient twitches unconsciously, the deviation caused by the patient's twitching is reduced by the restriction of the adjustable foot fixing assembly 5 on the heel.
