Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a compression hemostat for a surgical incision in the carotid artery surgical area. Background Technology

[0002] The most common carotid artery surgery is carotid endarterectomy, which involves exposing the carotid artery, cutting it open, and then completely removing the carotid endarterium and plaque.

[0003] Currently, during the surgery, doctors need to clamp the internal carotid artery, superior thyroid artery, external carotid artery, and common carotid artery in sequence, and then cut the carotid artery to prevent bleeding at the incision site. Then, the carotid intima and plaque can be removed, and the carotid artery is sutured. Next, the clamp on the superior thyroid artery is opened to check the patency of the blood vessel. Then, the clamps on the external carotid artery and common carotid artery need to be opened to remove plaque fragments and air flowing into the external carotid artery. Finally, the clamp on the internal carotid artery can be opened to restore cerebral blood flow. All of the above operations are performed manually by the doctor. Due to operational errors, the doctor may open the clamp on the internal carotid artery prematurely, which would allow plaque fragments and air to flow into the internal carotid artery, thus affecting the patient's brain. Summary of the Invention

[0004] In view of this, the present invention provides a carotid artery surgical incision compression hemostat, which can overcome the disadvantage that doctors may accidentally open the clips on the internal carotid artery prematurely due to operational errors, which may affect the patient's brain.

[0005] Technical solution:

[0006] A carotid artery surgical incision compression hemostat includes a first support plate, a controller, a second support plate, a mounting plate, universal rods, electric clamps, photoelectric sensors, a stabilizing component, and a releasing mechanism. The second support plate is rotatably connected to the upper part of the first support plate, and the controller is mounted on the second support plate. The mounting plate is rotatably connected to the upper part of the second support plate, and four universal rods are spaced apart on the mounting plate. Each universal rod has an electric clamp for clamping the patient's blood vessel at its bottom end. Each electric clamp is equipped with a photoelectric sensor for sensing the blood vessel. The photoelectric sensor and the electric clamp are electrically connected to the controller to enable the electric clamp to automatically clamp the blood vessel. The stabilizing component is used to stabilize the position of the second support plate, and the releasing mechanism is used to control the electric clamp to automatically release the blood vessel.

[0007] Preferably, the stabilizing component includes a rubber strip, a connecting ring, and a friction rod. The rubber strip is connected to the top front side of the first support plate, and the connecting ring is connected to the lower front side of the second support plate. The friction rod is connected to the front side of the connecting ring. When the friction rod rotates, it contacts the rubber strip to slow down the rotation speed of the second support plate through friction.

[0008] Preferably, the releasing mechanism includes a guide rail, a sliding clamping plate, a connecting spring, a first switch, a guide sleeve, a sliding rod, a roller, a return spring, and a locking assembly. A guide rail is connected to the left side of the mounting plate, and a sliding clamping plate is slidably connected to the guide rail. Four inclined slots are spaced apart on the right side of the sliding clamping plate. A connecting spring connects the front right side of the sliding clamping plate to the mounting plate. Four first switches are spaced apart on the top of the mounting plate, each corresponding to an electric clamp and electrically connected. Four guide sleeves are spaced apart on the top of the mounting plate, each corresponding to a first switch and located in front of its corresponding first switch. A sliding rod is slidably connected to each guide sleeve. Sliding the sliding rod to the left will contact the first switch, thereby controlling the corresponding electric clamp to automatically clamp the blood vessel. A roller is rotatably connected to the left end of each sliding rod, each roller corresponding to an inclined slot. A return spring connects each sliding rod to its adjacent guide sleeve. The locking assembly is used to lock the position of the sliding clamping plate.

[0009] Preferably, the locking assembly includes a connecting rod, a locking rod, a locking block, and a spring piece. The connecting rod is connected to the top of the mounting plate, and the locking rod is rotatably connected to the connecting rod. Multiple locking blocks are spaced apart on the middle right side of the sliding plate. The locking rod locks the locking blocks to lock the position of the sliding plate. A spring piece connects the locking rod and the connecting rod.

[0010] Preferably, the releasing mechanism further includes a limiting block, which is connected to the front of the sliding plate and contacts the guide rail. The limiting block is used to limit the sliding plate.

[0011] Preferably, it also includes a clamping mechanism, which includes a miniature air pump, a hollow frame, a first air tube, an air bag, a support rod, a second switch, and a vent valve. Four miniature air pumps are connected at intervals on the mounting plate, and each miniature air pump corresponds to an electric clamp. The bottom of each miniature air pump is connected to a hollow frame, and the air outlet of the miniature air pump is connected to the hollow frame. Two air bags for clamping blood vessels are connected to the inside of each electric clamp. The first air tube is connected between each air bag and its adjacent hollow frame. Two support rods are connected to each electric clamp, and the first air tube is fixedly connected to its adjacent support rod. A second switch is installed on one of the support rods, and a vent valve is installed on each hollow frame.

[0012] Preferably, it also includes a locking mechanism, which includes a second air pipe, a connecting cylinder, a lifting rod, a rack, a tension spring, a gear, and a third air pipe. The upper part of the first support plate and the upper part of the second support plate are both connected to the connecting cylinder. The upper connecting cylinder is connected to the hollow frame on the rear side by a second air pipe, and the two connecting cylinders are connected to the third air pipe. The connecting cylinder is slidably connected to the lifting rod, and the lifting rod is connected to the rack. The lifting rod and its adjacent connecting cylinder are connected to the tension spring. The lower front side of the second support plate and the left front side of the mounting plate are both connected to the gear. When the rack moves upward, it meshes with the gear to fix the position and angle of the second support plate and the mounting plate.

[0013] Preferably, it also includes a soft pad, with the right side of both the first support plate and the second support plate connected to the soft pad.

[0014] Beneficial effects:

[0015] 1. This invention, through the combination of photoelectric sensors and electric clamps, enables the electric clamps to automatically clamp the patient's blood vessels, reducing the doctor's operating steps. Then, through the cooperation of rollers and inclined grooves, the doctor can only control the electric clamps to release the patient's blood vessels in a pre-set sequence, which can prevent the doctor from making operational errors and prematurely releasing the internal carotid artery.

[0016] 2. When the electric clamp of the present invention clamps a patient's blood vessel, the corresponding air bladder will inflate and expand, thereby clamping the blood vessel more tightly and achieving a better clamping effect, and the air bladder will not damage the patient's blood vessel.

[0017] 3. When the electric clamp of the present invention clamps the patient's internal carotid artery, it drives the rack to move upward to lock the gear, thereby preventing the second support plate and the mounting plate from rotating arbitrarily, and thus avoiding damage to the patient's blood vessels.

[0029] 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.

[0030] Example 1: A surgical incision compression hemostat for the carotid artery surgical area, such as... Figures 1-6As shown, the device includes a first support plate 1, a controller 12, a second support plate 2, a mounting plate 3, universal rods 4, electric clamps 5, photoelectric sensors 6, a stabilizing component 7, and a release mechanism 8. The second support plate 2 is rotatably connected to the upper part of the first support plate 1. The controller 12 is installed on the left side of the second support plate 2. The mounting plate 3 is rotatably connected to the upper part of the second support plate 2. Four universal rods 4 are spaced apart on the mounting plate 3. Electric clamps 5 are installed at the bottom of each universal rod 4. The universal rods 4 can drive the electric clamps 5 to move and adjust their positions. Photoelectric sensors 6 are installed on each electric clamp 5. Both the electric clamps 5 and the photoelectric sensors 6 are electrically connected to the controller 12. When the doctor slightly lifts the patient's blood vessel, the photoelectric sensor 6 will sense the blood vessel and control the electric clamps 5 to automatically clamp the blood vessel through the controller 12, reducing the doctor's operation steps. The first support plate 1 is equipped with a stabilizing component 7, and the mounting plate 3 is equipped with a release mechanism 8.

[0031] like Figure 1 and Figure 3 As shown, the stabilizing component 7 includes a rubber strip 71, a connecting ring 72, and a friction rod 73. The rubber strip 71 is connected to the top front side of the first support plate 1, and the connecting ring 72 is welded to the lower front side of the second support plate 2. The friction rod 73 is connected to the front side of the connecting ring 72. When the friction rod 73 rotates, it will contact the rubber strip 71. The friction force can slow down the rotation speed of the second support plate 2.

[0032] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the releasing mechanism 8 includes a guide rail 81, a sliding plate 82, a connecting spring 821, a limiting block 822, a first switch 83, a guide sleeve 84, a sliding rod 85, a roller 851, a reset spring 86, a connecting rod 87, a locking rod 88, a locking block 89, and a spring piece 810. A guide rail 81 is welded to the left side of the mounting plate 3. A sliding plate 82 is slidably connected to the guide rail 81. Four inclined slots are spaced apart on the right side of the sliding plate 82. A connecting spring 821 connects the front right side of the sliding plate 82 to the mounting plate 3. A limiting block 822 is connected to the front of the sliding plate 82, and the limiting block 822 contacts the guide rail 81. Four first switches 83 are spaced apart on the top of the mounting plate 3. Each first switch 83 corresponds to an electric clamp 5 and is electrically connected. Four guide sleeves are spaced apart on the top of the mounting plate 3. The guide sleeve 84 corresponds one-to-one with the first switch 83, and the guide sleeve 84 is located in front of its corresponding first switch 83. Each guide sleeve 84 is slidably connected to a sliding rod 85. When the sliding rod 85 slides to the left, it will contact the first switch 83, thereby pressing the corresponding first switch 83 to control the corresponding electric clamp 5 to release the blood vessel. Each sliding rod 85 is rotatably connected to a roller 851, and the roller 851 corresponds one-to-one with the inclined groove. Each sliding rod 85 and its adjacent guide sleeve 84 is connected to a return spring 86. A connecting rod 87 is welded to the top of the mounting plate 3. A locking rod 88 is rotatably connected to the connecting rod 87. Multiple locking blocks 89 are welded at intervals in the middle right side of the sliding locking plate 82. The locking rod 88 locks the locking blocks 89. A spring piece 810 is connected between the locking rod 88 and the connecting rod 87.

[0033] First, place the device on the hospital bed, then have the patient lie down on the bed with their neck pressed against the first support plate 1 to fix its position. The patient should then turn their head to their side so that the surgical area of ​​their neck faces upwards. The doctor can then perform carotid artery surgery. When the doctor needs to clamp the internal carotid artery, superior thyroid artery, external carotid artery, and common carotid artery sequentially, the second support plate 2 can be rotated around the patient's neck, causing the connecting ring 72, friction rod 73, mounting plate 3, and electric clamp 5 to rotate. When the mounting plate 3 approaches the patient's neck incision, the friction rod 73 contacts the rubber strip 71. Under the action of friction, the rotation speed of the second support plate 2 to the right is slowed, thereby slowing the rotation speed of the mounting plate 3 and the electric clamp 5. To prevent damage to the patient's neck incision from the mounting plate 3 and the electric clamps 5, the four electric clamps 5 are positioned above the patient's internal carotid artery, superior thyroid artery, external carotid artery, and common carotid artery. Since the distribution of these arteries may vary slightly from patient to patient, the position of the electric clamps 5 can be adjusted using the universal rod 4. After adjustment, the patient's internal carotid artery, superior thyroid artery, external carotid artery, and common carotid artery can be gently lifted sequentially. When the photoelectric sensor 6 detects a blood vessel, it sends a signal. Upon receiving the signal, the controller 12 controls the corresponding electric clamp 5 to automatically clamp the patient's internal carotid artery, superior thyroid artery, external carotid artery, and common carotid artery. Then, the medical... The patient's carotid artery can be cut open, the carotid intima and plaque removed, and then the carotid artery sutured. At this point, only the roller 851 corresponding to the electric clamp 5 clamping the superior thyroid artery is aligned with the oblique groove, so that the doctor can only push the corresponding sliding rod 85 to the left. The corresponding reset spring 86 will be compressed, and the sliding rod 85 will press its corresponding first switch 83, thereby automatically releasing the electric clamp 5 clamping the superior thyroid artery to check the patency of the blood vessel. At the same time, the sliding rod 85 can drive the roller 851 to move to the left. Under the cooperation of the roller 851 and the oblique groove, the sliding plate 82 can be pushed forward, the connecting spring 821 is stretched, the sliding plate 82 drives the locking block 89 to move forward, and the locking block 89 will squeeze the locking rod 88 to rotate forward. When the spring 810 deforms, and a locking block 89 passes the locking lever 88, the spring 810 returns to its original shape, causing the locking lever 88 to rotate backward and lock the next locking block 89, thus locking the position of the sliding locking plate 82. At this time, only the roller 851 corresponding to the electric clamp 5 clamping the external carotid artery is aligned with the inclined groove. This reciprocating operation ensures that the electric clamp 5 clamping the internal carotid artery is released last, preventing operational errors by the doctor. Then, the second support plate 2 can be rotated to the left, causing the mounting plate 3 and the electric clamp 5 to rotate to the left away from the patient's neck incision. Then, the locking lever 88 is manually rotated forward to release the locking block 89. The spring 810 deforms, the connecting spring 821 returns to its original shape, causing the sliding locking plate 82 to slide backward and reset. Finally, the locking lever 88 is released.The spring 810 will return to its original position, causing the locking lever 88 to rotate backward and reset.

[0034] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes a clamping mechanism 9, which includes a miniature air pump 91, a hollow frame 92, a first air tube 93, an air bag 94, a support rod 95, a second switch 96, and a vent valve 97. Four miniature air pumps 91 are installed at intervals on the mounting plate 3. Each miniature air pump 91 corresponds to an electric clamp 5. The bottom of each miniature air pump 91 is connected to a hollow frame 92, and the air outlet of each miniature air pump 91 is connected to the hollow frame 92. Two air bags 94 are connected to the inside of each electric clamp 5. When the electric clamp 5 moves the air bags 94 inward, it can better clamp the blood vessels. The first air tube 93 is connected between each air bag 94 and its adjacent hollow frame 92. Two support rods 95 are connected to each electric clamp 5. The first air tube 93 is fixedly connected to its adjacent support rod 95. A second switch 96 is installed on one of the support rods 95. A vent valve 97 is installed on each hollow frame 92.

[0035] When the electric clamp 5 clamps the patient's blood vessel, it drives the two support rods 95 to move closer to each other. One support rod 95 presses the second switch 96 on the other support rod 95, thereby controlling the corresponding micro air pump 91 to start. The micro air pump 91 inflates the air bag 94 through the hollow frame 92 and the first trachea 93, allowing the air bag 94 to expand and clamp the blood vessel more tightly, achieving a better clamping effect. The air bag 94 will not damage the patient's blood vessel. When the electric clamp 5 releases the patient's blood vessel, it moves the air bag 94 away from the patient's blood vessel. Then, the doctor only needs to open the deflation valve 97 to allow the air bag 94 to deflate and shrink back through the hollow frame 92 and the first trachea 93.

[0036] like Figure 1 , Figure 9 and Figure 10As shown, it also includes a locking mechanism 10, which includes a second air pipe 101, a connecting cylinder 102, a lifting rod 103, a rack 104, a tension spring 105, a gear 106, and a third air pipe 107. The upper part of the first support plate 1 and the upper part of the second support plate 2 are both connected to the connecting cylinder 102. The upper connecting cylinder 102 is connected to the hollow frame 92 on the rear side by the second air pipe 101, and the two connecting cylinders 102 are connected to the third air pipe 107. The lifting rod 103 is slidably connected to the connecting cylinder 102. The rack 104 is connected to the lifting rod 103. The tension spring 105 is connected between the lifting rod 103 and its adjacent connecting cylinder 102. The lower front side of the second support plate 2 and the left front side of the mounting plate 3 are both connected to the gear 106. When the rack 104 moves upward, it will mesh with the gear 106, thereby locking the angle of the gear 106 to fix the position and angle of the second support plate 2 and the mounting plate 3.

[0037] When the electric clamp 5 corresponding to the internal carotid artery clamps the patient's internal carotid artery, its corresponding miniature air pump 91 injects air into the connecting cylinder 102 through the hollow frame 92, the first air pipe 93, the second air pipe 101, and the third air pipe 107. This pushes the lifting rod 103 upward, stretching the tension spring 105. The lifting rod 103 drives the rack 104 upward to lock the gear 106, thus preventing the second support plate 2 and the mounting plate 3 from rotating arbitrarily and avoiding damage to the patient's blood vessels. When the electric clamp 5 corresponding to the internal carotid artery releases the patient's internal carotid artery, the air in the connecting cylinder 102 can be released through the hollow frame 92, the first air pipe 93, the second air pipe 101, and the third air pipe 107. The tension spring 105 returns to its original state, driving the lifting rod 103 and the rack 104 downward to reset, causing the rack 104 to release the gear 106. The second support plate 2 and the mounting plate 3 can then continue to rotate away from the patient's neck.

[0038] It also includes a soft pad 11, with the soft pad 11 connected to the right side of both the first support plate 1 and the second support plate 2; under the action of the soft pad 11, the first support plate 1 and the second support plate 2 can be more comfortable when they are against the patient's neck.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
