Description

Technical Field

[0001] The present invention relates to the technical field of surgical auxiliary instruments, in particular to a surgical auxiliary tool. Background Art

[0002] The main purpose of coronary angiography is to determine whether there is coronary artery disease, select treatment options and judge prognosis. For example, patients with symptoms of angina pectoris (especially those who are ineffective with drug treatment or have high-risk factors found through non-invasive examinations), middle-aged and elderly patients undergoing congenital heart disease surgery, and patients with unexplained chest pain all need coronary angiography. The general operating steps of coronary angiography are: insert a puncture needle into the radial artery or femoral artery, then pull out the inner core, insert the super-slippery guide wire from the puncture needle into the blood vessel, then insert the catheter along the super-slippery guide wire, then withdraw the super-slippery guide wire, and then connect the syringe containing contrast agent to the catheter for manual injection. The following problems exist in the above operation: 1. When inserting the super-slippery guidewire, in order to prevent bleeding at the puncture point, the medical staff needs to press the vicinity of the puncture point with one hand to prevent blood from flowing out when the super-slippery guidewire enters. However, this means that the medical staff can only insert the super-slippery guidewire with one hand. The super-slippery guidewire has a small diameter and is difficult to pinch. In addition, the medical staff wear gloves on their hands, which are prone to slippage, affecting the insertion of the super-slippery guidewire, increasing the difficulty of the medical staff's work, and reducing efficiency. 2. When injecting contrast agents, it is necessary to control the speed of squeezing the syringe, and it is best to inject at a uniform speed to prevent the injection speed from causing ventricular fibrillation. However, the current injection speed depends entirely on the doctor's hand strength. Compared with machines, manual injection is difficult to achieve uniform speed, and the strength is not easy to control. It is very easy to suddenly increase the injection speed, which in turn causes discomfort to the patient. Although some existing devices can achieve automatic uniform injection, these devices are large in size, and the space in the operating room is limited, so too many devices cannot be placed. In addition, the device has a single function and has no other functions except uniform injection, so it is not practical. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a surgical auxiliary tool, which effectively solves the problems of low efficiency in inserting super-slip guide wire and inconvenience in uniform injection of contrast agent.

[0004] The technical solution is as follows: the present invention comprises a main body box, wherein two rotating disks distributed up and down and axially arranged left and right are arranged in the main body box, the two rotating disks can rotate and rotate in opposite directions, the front and rear sides of the rotating disks are respectively provided with push grooves in the front and rear directions, the upper and lower sides of the right side wall in the main body box are respectively provided with mouth-shaped grooves, two moving rods distributed front and back are slidably connected in the mouth-shaped grooves, the left ends of the moving rods are provided with plugs inserted into the push grooves on the corresponding sides, the opposite ends of the two moving rods opposite to each other are respectively provided with connecting rods in the upper and lower directions, the free ends of the connecting rods are slidably connected with a pressing box, and a giving way groove which runs through front and back and opens to the right is arranged on the main body box, and the giving way groove is located between the two pressing boxes opposite to each other up and down; The main box is slidably connected with a fixed plate which is in an inverted L shape and the rear end of which passes through the main box. The upper turntable can move left and right as the fixed plate moves forward and backward. The main box is slidably connected with an inverted L-shaped push plate located on the inner side of the fixed plate. The rear end of the push plate passes through the main box. An extension plate which is in an inverted T shape and the front end of which passes through the main box is slidably connected to the push plate. The push plate and the extension plate are respectively provided with push rods in the front and rear directions. The rear end surface of the push rod on the extension plate can contact the front end surface of the push rod on the push plate. When the upper turntable moves to the left, the push plate can move backward as the upper turntable rotates.

[0005] The beneficial effects of the present invention are: 1. No need for a person to hold the guide wire tightly, and use the squeezing of two elastic anti-slip blocks opposite to each other to achieve clamping and fixing the guide wire. Then, the rotation of the turntable is used to achieve continuous movement of the elastic anti-slip block, so that the guide wire is continuously fed into the human body without anyone holding the guide wire in, which improves the comfort of the operator and improves the efficiency of the guide wire placement, which is more efficient and more stable; 2. The fixing plate, bolus injection plate, and extension plate that can be stored in the main body box can be reduced to the space occupied by the device, making the structure more compact, one machine and two-purpose, reducing the number of devices used during surgery, saving space and cost more, achieving uniform injection of contrast agent, improving patient comfort, and increasing the practicality of the device.

The right end of the moving rod 5 is inserted into the stabilizing groove 25 and is provided with a stabilizing block 26, and the stabilizing block 26 is slidably connected to the stabilizing groove 25.

[0025] In order to better compress the guide wire and facilitate placing the guide wire between two relatively upper and lower pressing boxes 8, a compression spring is provided between the pressing box 8 and its corresponding moving rod 5.

[0026] In order to limit the position of the guide wire and prevent the guide wire from tilting, so as to ensure that the guide wire can be smoothly squeezed by the two elastic anti-sliding blocks 27 that are relatively upper and lower, an elastic rod 30 in the front-rear direction is provided at the left side of the upper end of the让位槽.

[0027] In order to better fix the syringe, a groove with an upward opening is provided at the rear end of the fixing plate 9. A plurality of card slots 31 that are distributed in the front-rear direction and penetrate up and down are provided on the fixing plate 9.

The free end of the binding band 34 penetrates through the fixing box 32 and is provided with a pull ring 35. A card box 36 with a rightward opening is provided at the right side of the rear end of the fixing plate 9. A hook 37 that can be inserted into the pull ring 35 is provided in the card box 36.

[0028] In order to prevent the fixing plate 9 and the extension plate 11 from being randomly removed from the main body box 1, limiting slots 38 with rightward openings are respectively provided at the front and rear sides of the right end of the fixing plate 9. A limiting rod 39 that is in an inverted L shape and can be inserted into the limiting slots 38 is slidably connected to the rear end of the main body box 1. A compression spring is provided between the right end of the limiting rod 39 and the main body box 1. Magnets 40 are respectively provided at the upper end of the extension plate 11 and the rear end of the main body box 1, and the two magnets 40 can attract each other.

[0029] In order to facilitate moving the main body box 1, a handle is provided at the upper end of the main body box 1.

[0030] When the present invention is in use, the initial state is that the limiting rod 39 is inserted into the rear limiting slot 38, the two magnets 40 are adsorbed together, and the拨动板 24 is located to the right of the拨板 23; When it is necessary to deliver the guide wire into the patient's body, the slide bar 28 is pushed upward, and the slide bar 28 moves upward along the slide groove for a certain distance and then contacts the fixed rod 29, and then pushes the fixed rod 29 to move upward, and the fixed rod 29 drives the upper pressure box 8 to move upward, and the compression spring contracts under the force, and the guide wire is placed between the two elastic anti-sliding blocks 27 opposite to each other along the yielding groove. At this time, under the obstruction of the elastic rod 30, the guide wire will not tilt significantly, thereby ensuring that the elastic anti-sliding block 27 can stably clamp the guide wire, and push the slide bar 28 to the right to make the slide bar 28 move along the slide groove to the lower end limit position. At this time, the two elastic anti-sliding blocks 27 opposite to each other above and below squeeze and fix the guide wire, and the rear end of the guide wire is inserted into the puncture needle, and the motor 13 is started; The motor 13 drives the upper rotating shaft to rotate clockwise, and the upper rotating shaft drives the lower rotating shaft to rotate counterclockwise through the cross transmission of the pulley and the transmission belt 14, and the turntable 2 rotates synchronously and drives the front moving rod 5 to move inward along the mouth-shaped groove 4 and the rear moving rod 5 to move outward along the mouth-shaped groove 4 through the push groove 3 and the plug column 6, that is, the two moving rods 5 on the front side move relative to each other, the compression spring contracts under force, the pressure box 8 drives the pressure plate and the elastic anti-sliding block 27 to firmly fix the guide wire, and the two moving rods 5 on the rear side move away from each other, thereby relaxing the squeezing of the guide wire; When the front moving rod 5 moves to the inner limit position of the mouth-shaped groove 4, the rear moving rod 5 moves to the outer limit position. At this time, as the turntable 2 rotates, the two front moving rods 5 move backward while keeping the guide wire clamped, so as to send the guide wire into the patient's body. The two rear moving rods 5 move forward along the mouth-shaped groove 4, and the rear moving rod 5 is located above the front moving rod 5. When the front moving rod 5 moves to the rear limit position of the mouth-shaped groove 4, the rear moving rod 5 moves to the front limit position. At this time, the front moving rod 5 The guide wire is pressed outward to release the pressure on the guide wire, and the rear moving rod 5 moves inward to press the guide wire, and so on, so that the guide wire is sent into the patient's body without manual delivery, reducing the workload of medical staff, and the guide wire is firmly fixed by the elastic anti-sliding block 27. Moreover, when the two moving rods 5 in the same mouth-shaped groove 4 are opposite to each other, the two sets of elastic anti-sliding blocks 27 opposite to each other above and below both compress and fix the guide wire, thereby ensuring that the guide wire is always in a clamped state, preventing the guide wire from slipping outward, and ensuring the stability of the guide wire delivery; When the length of the guide wire inserted into the human body reaches the required length, the motor 13 is turned off, and the slide bar 28 is pushed upward to move the pressing box 8 away from the guide wire, thereby releasing the squeezing and fixing of the guide wire, and then the main box 1 is removed from the guide wire, and then the catheter insertion and other operations can be performed normally; When contrast agent injection is required, the limiting rod 39 is pulled to the right to release the limiting of the fixed plate 9, and the fixed plate 9 is pulled backward, and the fixed plate 9 drives the protrusion 16 to move backward. After the protrusion 16 moves backward for a certain distance, its inclined surface contacts with the movable plate 15 and pushes the movable plate 15 to move to the left, and the movable plate 15 drives the upper turntable 2 to move to the left. The spring is forced to shrink, and the toggle plate 24 gradually approaches and inserts in front of the two adjacent toggle plates 23. When the limiting groove 38 on the front side is opposite to the limiting rod 39 on the left and right, the limiting rod 39 moves to the left and inserts into the limiting groove 38 on the front side under the action of the compression spring, and the position of the fixed plate 9 is limited; Pull the extension plate 11 forward, the two magnets 40 move away from each other, the extension plate 11 drives the ejector rod 12 thereon to move forward, the elastic band 18 is stretched by force, and the guide block 21 moves forward along the guide groove 19. When the guide block 21 moves to the front limit position of the guide groove 19, the ejector rod 12 on the extension plate 11 is located in front of the ejector rod 12 on the injection push plate 10, and the push block 22 on the left side is pushed to the right, and the push block 22 pushes the ejector rod 12 to move to the right, and the guide block 21 moves to the right along the guide groove 19 synchronously. When the guide block 21 moves to the right limit position of the guide groove 19, the two ejector rods 12 are opposite to each other front and back, and the extension plate 11 is released. The extension plate 11 moves backward under the action of the elastic band 18, and the guide block 21 moves backward along the guide groove 19, and the rear end face of the ejector rod 12 on the extension plate 11 contacts the front end face of the ejector rod 12 on the injection push plate 10; Place the syringe filled with contrast agent and after exhausting the air on the fixing plate 9, so that the nipple of the syringe extends out from the groove, and the protrusion on the syringe barrel is inserted into the corresponding card slot 31, pull the pull ring 35, the pull ring 35 drives the binding belt 34 to move outward, the coil spring 33 is forced to shrink, and the pull ring 35 is covered on the syringe and then hung on the hook 37. At this time, the position of the syringe is fixed under the action of the coil spring 33, and the extension plate 11 is pushed backward, and the extension plate 11 pushes the injection plate 10 to move backward. When the rear end of the injection plate 10 contacts the piston handle on the syringe, the extension plate 11 is stopped and the motor 13 is started; The motor 13 drives the upper turntable 2 to rotate clockwise via the upper rotating shaft, and the turntable 2 pushes the dial plate 23 to move backward via the dial plate 24, and the dial plate 23 pushes the ejector rod 12 and the injection plate 10 to move backward, and the extension plate 11 moves backward synchronously, and the injection plate 10 squeezes and pushes the syringe piston handle backward, thereby injecting the contrast agent into the patient's body at a uniform speed to increase the patient's comfort. At this time, although the turntable 2 still drives the moving rod 5 to move, there is no guide wire between the two upper and lower elastic anti-sliding blocks 27, so it is in an idling state, which does not affect the normal injection of the contrast agent; When the injection of contrast agent is completed, the motor 13 is turned off, the pull ring 35 is removed from the hook 37, and the band 34 is wound around the rotating column again under the action of the coil spring 33, the fixation of the syringe is released, the syringe is removed from the fixed plate 9, and the extension plate 11 is pulled forward, and the extension plate 11 drives the injection plate 10 to move forward, and the dial plate 23 drives the turntable 2 to rotate in the opposite direction through the dial plate 24. When the rear end of the injection plate 10 contacts the main box 1, the extension plate 11 is stopped, and the limit rod 39 is pulled rightward to release the limit of the fixed plate 9, and the fixed plate 9 is pushed forward. The protrusion 16 moves forward synchronously. When the protrusion 16 is out of contact with the movable plate 15, the turntable 2 on the upper side moves to the right under the action of the spring, so that the toggle plate 24 is away from the toggle plate 23, so that the limit rod 39 is inserted into the limit groove 38 on the rear side again, and the position of the fixed plate 9 is limited. At this time, the rear end of the fixed plate 9 contacts the rear end of the injection plate 10, and the position of the injection plate 10 is limited; Pull the extension plate 11 forward again to move the guide block 21 to the front limit position of the guide groove 19, push the push block 22 on the right side to the left, and the push block 22 pushes the top rod 12 on the extension plate 11 to move to the left, and the guide block 21 moves from the right limit position of the guide groove 19 to the left limit position of the guide groove 19, release the extension plate 11, and under the action of the elastic band 18, the extension plate 11 moves backward, and the guide block 21 moves backward along the left side of the guide groove 19 simultaneously, and the magnet 40 on the extension plate 11 gradually approaches the magnet 40 on the main box 1. When the two magnets 40 are adsorbed together, the position of the extension plate 11 is limited, thereby reducing the space occupied and facilitating storage and movement. Then, corresponding disinfection can be carried out according to medical requirements.

[0031] The motor 13 and its connection method in the present invention are both prior art and will not be described in detail here.

[0032] The present invention is novel in conception, ingenious in structure, easy to operate and highly practical. The stabilizing groove and the stabilizing block are arranged to keep the moving rod in a horizontal state at all times, thereby ensuring that the two elastic anti-sliding blocks opposite to each other can clamp the guide wire opposite to each other up and down. The pressure box, the pressure spring, the connecting rod, the pressure plate and the elastic anti-sliding block are arranged to stably fix the guide wire, ensure that the guide wire is always in a clamped state, thereby ensuring the stability of the guide wire delivery. The turntable, the push groove and the plug are arranged to ensure that the guide wire is continuously delivered into the patient's body, thereby improving the efficiency of the guide wire delivery. The elastic rod is used to limit the guide wire, ensuring that the guide wire keeps entering the patient's body in a straight line and smoothly. The fixing plate, the fixing box, the binding belt and the turntable are arranged to ensure that the guide wire is in a straight line and smoothly. The syringe is effectively fixed by the setting of columns, coil springs, pull rings, card boxes, hooks, card slots and grooves to prevent the position of the syringe from changing during the injection process; the extension plate and the injection plate are connected and stored by the setting of the injection plate, ejector rod, extension plate, elastic band, push block, guide slot and guide block to reduce the space occupied; the upper turntable and the injection plate are connected by the setting of the toggle plate, paddle plate, moving plate, bump, spring and fixed plate, so that the motor drives the injection plate to inject at a uniform speed, thereby achieving the purpose of uniform injection of contrast agent, which is safer and more reliable, improves the patient's comfort, and can be effectively stored when not in use to reduce the space occupied and meet the needs of one machine for multiple uses.

[0033] It can be seen that the use of a surgical auxiliary tool provided by the present invention can effectively solve the problems of low efficiency in inserting a super-smooth guide wire and inconvenience in injecting contrast agent at a uniform speed. This structure is simple to operate, easy to use, and improves surgical efficiency.
