Description

Technical Field

[0001] The present invention relates to the field of brain hematoma removal, and more specifically, to a hematoma removal device for patients with cerebral hemorrhage and its usage method. Background Art

[0002] The hematoma removal of patients with cerebral hemorrhage is a complex process, and the choice of method depends on various factors, including the amount of bleeding, the bleeding site, the age and general condition of the patient, and the time from the onset of bleeding to the operation, etc.

[0003] Common hematoma removal methods for patients with cerebral hemorrhage include craniotomy for hematoma removal, drilling for hematoma cavity drainage, neuroendoscopic surgery, and directional hematoma aspiration. Among them, craniotomy for hematoma removal is a traditional surgical method, which is applicable to critically ill patients with large hematomas or those who have developed brain herniation.

[0004] Craniotomy for hematoma removal is a surgical method that opens the skull to remove the intracranial hematoma in order to achieve the purpose of reducing intracranial pressure, stopping bleeding, and restoring brain tissue function. This surgery is usually used for intracranial hematomas caused by brain trauma, cerebral hemorrhage, etc., including methods such as forming a bone flap craniotomy and subtemporal decompression and bone window craniotomy. During the operation, precise operation under a microscope is required to reduce damage to normal brain tissue.

[0005] When traditionally performing craniotomy for hematoma removal, multiple medical staff are required to fix and support the patient's head, and the suction tube also needs to be held to prevent the tube from rubbing against the patient's brain. This method not only occupies a lot of medical resources but also is not convenient for moving the patient's head, and it is easy to cause situations such as cerebrospinal fluid leakage during movement.

[0019] A method for using a hematoma removal device for cerebral hemorrhage patients adopts the above-mentioned hematoma removal device for cerebral hemorrhage patients.

[0020] S1: First, open the upper fixing ring and the lower fixing ring, and then refix the upper fixing ring and the lower fixing ring at the patient's neck position.

[0021] S2: Place the second fixing member at the top of the patient's skull so that the patient's head is located between the second fixing member and the first fixing member.

[0022] S3: Rotate the upper housing to drive the second fixing member and the first fixing member to approach each other. After waiting for stable clamping, place the second fixing member and the first fixing member on the corresponding moving frames.

[0023] S4: Slide the support rod so that the support rod fits with the first fixing member and the second fixing member, and then rotate the locking bolt to fix the position of the support rod.

[0024] S5: Use the tightening member to drive the second fixing member and the first fixing member to rotate to change the orientation of the patient's skull.

[0025] S6: Make a question mark-shaped incision at the patient's injury site, lift the patient's scalp, use a skull drill to drill holes in the patient's skull, and then use a milling cutter to cut so that the hematoma is exposed.

[0026] S7: Turn on the drainage pump. The doctor holds the lower anti-disconnection housing and slides it to the end of the suction tube. Under the action of the drainage pump, the suction tube clears the patient's cerebral hematoma.

[0027] S8: After the clearance, place the suction tube at the patient's hematoma position, then use fixing nails to fix the patient's skull, suture the patient's scalp, and bandage the patient's head with a bandage.

[0028] S9: Disassemble the connecting tube from the drainage pump and connect it to the drainage bag.

[0029] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0030] In the above solution, by setting the first fixing member, the second fixing member, and the tightening member, during the craniotomy hematoma removal operation, the doctor can operate on the patient's head more conveniently, reduce the personnel requirements, do not need many medical staff to support, and also prevent the situation that the pipeline scratches the patient's wound, so that the doctor can focus all attention on the patient, improve the surgical safety, reduce the personnel requirements, and improve the convenience of using the device.

[0031] By setting the lower anti - detachment housing, after bandaging is completed, the lower anti - detachment housing can be slid to the top of the suction tube. Then, at this time, the convex block is engaged with the card slot on the locking flap. Then, rotate the lower anti - detachment housing, and the length of the lower anti - detachment housing and the first threaded cylinder increases until the lower anti - detachment housing abuts against the patient's head and the convex block abuts against the locking flap. At this time, the suction tube outside the patient can be fixed, preventing the suction tube from shaking or even slipping, and preventing the situation that the patient's later recovery is infected due to shaking.

[0032] By setting the tightening member and the moving frame, the device can adapt to people with different head lengths, can produce a better clamping effect, and improve the stability of the device.

[0033] By setting the upper mating plate and the lower mating plate, when in use, the doctor only needs to rotate the tightening member to drive the first fixing member and the second fixing member to rotate, then the orientation of the patient's head can be changed, and directly releasing the hand can achieve automatic locking and prevent movement, reducing the complexity during use and making it more convenient to use.

[0034] By setting the connecting member, it can prevent excessive clamping of the patient's head, prevent unnecessary damage to the patient, and can also adjust the direction of the upper housing, facilitating changing the orientation of the suction tube, making it more convenient to fix the suction tube and playing a supporting role.

[0035] By setting the connecting plate, only by pressing the lower housing can the connection between the tightening member, the second fixing member, and the first fixing member be released. When the lower housing is released, it can re - fix the second fixing member and the first fixing member, can conveniently adjust the position of the upper housing, more conveniently adjust the force - applying angle of the upper housing, prevent it from blocking the operation, and also make it more convenient for the doctor to rotate the second fixing member and the first fixing member.

[0058] Such as Figures 1 to 12As shown in the figure, an embodiment of the present invention provides a hematoma removal device for patients with cerebral hemorrhage, including a base 1. A support frame 11 is fixedly installed on the upper surface of the base 1. A rotating ring 2 is rotatably installed on the upper surface of the support frame 11. Two moving frames 3 are provided on the rotating ring 2. The moving frame 3 includes a support rod 31, and the support rod 31 is arc-shaped. A first fixing component 4 and a second fixing component 5 are respectively arranged on the two moving frames 3. The first fixing component 4 and the second fixing component 5 are used to fix the patient's head. A tightening member 6 for connection is arranged between the first fixing component 4 and the second fixing component 5. The tightening member 6 includes an upper housing 61. Connecting members 62 are fixedly installed on both sides of the upper housing 61. First connecting rods 63 are rotatably installed on both sides of the upper housing 61 corresponding to the connecting members 62. The connecting member 62 is sleeved outside the first connecting rod 63. Second connecting rods 64 are provided on the sides of the two first connecting rods 63 away from each other. A second threaded cylinder 641 is fixedly installed at the end of the second connecting rod 64 close to the first connecting rod 63. A threaded groove 631 adapted to the second threaded cylinder 641 is opened at the end of the first connecting rod 63 close to the second connecting rod 64. A guide rail 66 is fixedly installed on the side of the upper housing 61 adjacent to the connecting member 62. Two symmetrically arranged locking flaps 67 are slidably installed on the guide rail 66. A suction tube 69 for sucking cerebral hematoma is arranged below between the two locking flaps 67. A connecting tube 691 for connecting the input end of a drainage pump is arranged above between the two locking flaps 67. A lower anti-disengagement housing 70 is slidably sleeved outside the suction tube 69.

[0059] Before actual use, the patient is first given general anesthesia. Then, the first fixing member 4 and the second fixing member 5 are removed from the support rod 31. Next, the second fixing member 5 is placed at the top of the patient's skull, and the first fixing member 4 is put around the patient's neck. At this time, the upper housing 61 is rotated. The upper housing 61 drives the connecting member 62 to rotate, and the rotation of the connecting member 62 will drive the first connecting rod 63 to rotate. When the first connecting rod 63 rotates, the length between the second threaded cylinder 641 and the first connecting rod 63 will be shortened, thereby changing the distance between the first fixing member 4 and the second fixing member 5 until the first fixing member 4 and the second fixing member 5 clamp the patient's head. Then, the patient lies flat and the first fixing member 4 and the second fixing member 5 are placed on the corresponding support rods 31. The support rods 31 play a supporting role for the first fixing member 4 and the second fixing member 5. The distance between the two support rods 31 is adjusted to fit the first fixing member 4 and the second fixing member 5. At this time, the patient's head is supported by the support rods 31. The doctor can drive the first fixing member 4 and the second fixing member 5 to rotate on the surface of the support rod 31 by pushing the tightening member 6. The support rod 31 is set to be arc-shaped to better fit the rotation of the human head. When rotated to the required position, the first fixing member 4 and the second fixing member 5 can automatically stop. At this time, the doctor makes a question mark-shaped incision in the patient's wound, then lifts the patient's scalp, drills a hole with a skull drill, and then uses a milling cutter to cut along the position of the drilled hole. After cutting is completed, the skull is removed. The doctor holds the lower anti-disconnection housing 70 and slides and moves along the suction tube 69 without contacting the suction tube 69. Then, the drainage pump is turned on, and the suction tube 69 can remove the congestion and blood clots at the hematoma position of the patient.

[0060] After the cleaning is completed, the lower anti-disconnection housing 70 is slid back above the suction tube 69. Then, the lower end of the suction tube 69 is left at the hematoma position of the patient. Then, the patient's skull is re-fixed with fixing nails, and then the patient's scalp is re-sutured. Then, the incision is bandaged. Since the locking flap 67 clamps the suction tube 69 during the debridement process, there is no need for the doctor to hold the tube by hand.

[0061] By setting the first fixing member 4, the second fixing member 5, and the tightening member 6, this device enables the doctor to operate on the patient's head more conveniently during the craniotomy hematoma removal surgery, reduces the personnel requirements, does not require many medical staff to support, and also prevents the situation of the tube rubbing against the patient's wound, enabling the doctor to fully focus on the patient, improving the surgical safety, reducing the personnel requirements, and enhancing the convenience of device use.

[0062] Such as Figures 3 to 5As shown, at the ends of the suction tube 69 and the connecting tube 691 that are close to each other, limiting rings 692 are fixedly installed. Both of the two limiting rings 692 are located between the two locking petals 67. A locking screw 68 is installed on the guide rail 66 by means of screw fit. One end of the locking screw 68 is rotatably installed on the side surface of the corresponding locking petal 67. Above the lower anti-disengagement housing 70, there is an upper anti-disengagement housing 71. The lower surface of the upper anti-disengagement housing 71 is fixedly installed with a first threaded cylinder 72. The first threaded cylinder 72 is clamped inside the lower anti-disengagement housing 70 by means of screw fit. The lower anti-disengagement housing 70, the upper anti-disengagement housing 71, and the first threaded cylinder 72 are all slidably sleeved on the outer surface of the suction tube 69. The upper surface of the upper anti-disengagement housing 71 is fixedly installed with a plurality of evenly distributed bumps 73. The lower surface of the locking petal 67 is provided with a plurality of card slots adapted to the bumps 73. During use, the distance between the two locking petals 67 can be changed by rotating the locking screw 68, so as to clamp or release the limiting ring 692. The guide rail 66 is used to keep the locking petals 67 sliding stably.

[0063] After the dressing is completed, the lower anti-disengagement housing 70 can be slid to the top end of the suction tube 69. At this time, the bumps 73 are engaged with the card slots on the locking petals 67. Then, rotate the lower anti-disengagement housing 70. The length of the lower anti-disengagement housing 70 and the first threaded cylinder 72 increases until the lower anti-disengagement housing 70 abuts against the patient's head and the bumps 73 abut against the locking petals 67. At this time, the suction tube 69 outside the patient's body can be fixed, preventing the suction tube 69 from shaking or even slipping, and preventing the occurrence of infection during the patient's later recovery due to shaking.

[0064] As Figure 12 As shown, the first fixing component 4 includes a symmetrically arranged upper fixing ring 41 and a lower fixing ring 42. The second fixing component 5 includes a side fixing ring 51. On the sides of the upper fixing ring 41 and the lower fixing ring 42 away from the side fixing ring 51, first baffles 43 are fixedly installed. On the sides of the side fixing ring 51 away from the first fixing component 4, second baffles 55 are fixedly installed. The second baffles 55 and the first baffles 43 can clamp the two support rods 31 to fix the positions of the second fixing component 5 and the first fixing component 4. On the sides of the second baffles 55 and the first baffles 43 that are close to each other, bosses 52 are fixedly installed. On the sides of the two bosses 52 that are close to each other, a plurality of evenly distributed clamping rods 53 are fixedly installed. The bosses 52 play a supporting role to prevent the clamping rods 53 from being stressed. In the middle of the side fixing ring 51, a stop block 54 is fixedly installed through a bracket. The upper fixing ring 41 and the lower fixing ring 42 are detachably spliced. On the sides of the upper fixing ring 41 and the lower fixing ring 42 close to the second fixing component 5, soft pads 44 are fixedly installed.

[0065] When fixing, disassemble the upper fixing ring 41 and the lower fixing ring 42, then place the upper fixing ring 41 and the lower fixing ring 42 around the patient's neck, and then fix the upper fixing ring 41 and the lower fixing ring 42. Place the stopper 54 on the top of the patient's skull, and then rotating the upper housing 61 can drive the first fixing member 4 and the second fixing member 5 to approach each other. The stopper 54 can abut against the top of the patient's skull, while the upper fixing ring 41 and the lower fixing ring 42 can abut against the patient's mandible. The soft pad 44 can prevent damage to the patient's mandible during clamping.

[0066] As Figure 2 shown, both ends of the support rod 31 are slidably clamped with extension rods 32. The lower surface of the extension rod 32 is fixedly installed with a first sliding rod 33. The upper surface of the rotating ring 2 is provided with a plurality of first sliding grooves 21 corresponding to the first sliding rod 33. The first sliding rod 33 is slidably clamped inside the corresponding first sliding groove 21. The extension rod 32 is installed with a locking bolt 34 through threaded cooperation. The upper surface of the support rod 31 is fixedly installed with a plurality of T-shaped teeth 35 adapted to the clamping rod 53.

[0067] During use, first loosen the locking bolt 34, and then slide the support rod 31. At this time, the extension rod 32 will slide along the support rod 31, so as to ensure that the support rod 31 can always be supported by the extension rod 32 when sliding. When sliding to a suitable position, tighten the locking bolt 34. At this time, the position of the support rod 31 can be fixed. Furthermore, by setting the tightening member 6 and the moving frame 3, the device can be adapted to people with different skull lengths, can produce a better clamping effect, and improve the stability of the device.

[0068] As Figures 3 to 5 、 Figures 8 to 12As shown, a lower matching plate 58 is provided on the side of the side fixing ring 51 away from the first fixing part 4, and the lower matching plate 58 is fixedly installed on the support rod 31. An annular groove 551 is provided on the side of the second baffle plate 55 away from the first fixing part 4. A support plate 56 is provided on the side of the side fixing ring 51 away from the first fixing part 4. The ends of the support plate 56 are slidably clamped in the inner two sides of the annular groove 551. An upper matching plate 57 is provided below the support plate 56. A plurality of evenly distributed guide rods 571 are fixedly installed on the upper surface of the upper matching plate 57. The support plate 56 is slidably sleeved on the guide rods 571. On the outer surface, a plurality of evenly distributed first springs 572 are fixedly connected between the support plate 56 and the upper mating plate 57, a first latch tooth 573 is fixedly installed on one end of the lower surface of the upper mating plate 57, and a second latch tooth 574 is fixedly installed on the other end of the lower surface of the upper mating plate 57, and a plurality of evenly distributed first mating teeth 581 are provided on the side of the upper surface of the lower mating plate 58 corresponding to the first latch tooth 573, and a plurality of evenly distributed second mating teeth 582 are provided on the position of the upper surface of the lower mating plate 58 corresponding to the second latch tooth 574, and a center groove 583 is provided in the middle of the upper surface of the lower mating plate 58.

[0069] When in use, the doctor holds the upper shell 61, and the upper shell 61 is connected to the corresponding first fixing part 4 and second fixing part 5 through the connecting piece 62, the first connecting rod 63, the second connecting rod 64, and the limiting shell 65, and then drives the whole to revolve, thereby driving the first fixing part 4 and the second fixing part 5 to rotate, and can adjust the tilt position of the patient's head. When the first fixing part 4 and the second fixing part 5 rotate, the upper fixing ring 41, the lower fixing ring 42 and the side fixing ring 51 will roll along the surface of the corresponding support rod 31, and the T-shaped tooth 35 and the clamping rod 53 engage with each other. When the first fixing part 4 and the second fixing part 5 roll, the annular groove 551 is set on the second fixing part 5. , so it will drive the support plate 56 to move horizontally. When the support plate 56 moves, the upper matching plate 57 is also driven to move. When the support plate 56 moves toward the first latch tooth 573, the first latch tooth 573 will be pushed by the first matching tooth 581 and can move. At this time, the second latch tooth 574 is located inside the central groove 583. When the doctor lets go, because the support rod 31 is arc-shaped, the second fixing component 5 and the first fixing component 4 have a tendency to return to their original positions under the action of the patient's head gravity. At this time, under the action of the first spring 572, the first latch tooth 573 will resist the first matching tooth 581 to prevent it from moving. The same is true when the support plate 56 moves toward the second latch tooth 574.

[0070] Furthermore, by providing the upper mating plate 57 and the lower mating plate 58, when the device is in use, the doctor only needs to rotate the tightening member 6 to drive the first fixing member 4 and the second fixing member 5 to rotate, thus changing the orientation of the patient's head. And simply releasing the hand can achieve automatic locking to prevent movement, reducing the complexity during use and making it more convenient to use.

[0071] As Figure 5 shown, the lower housing 611 is slidably clamped inside the lower end of the upper housing 61. A second spring 614 is fixedly connected between the upper housing 61 and the lower housing 611. Both ends of the upper surface of the lower housing 611 are rotatably installed with connecting plates 613. Symmetric linear chutes 612 are provided at the upper end positions of the inner side walls of the upper housing 61. The upper ends of the connecting plates 613 are slidably clamped inside the linear chutes 612. The connecting plates 613 are inclined. One end of the first connecting rod 63 away from the thread groove 631 is slidably clamped with a first central sliding rod 632. A third threaded cylinder 642 is slidably clamped inside the second connecting rod 64. One end of the first central sliding rod 632 close to the third threaded cylinder 642 is clamped inside the third threaded cylinder 642 by thread fit. Multiple mating slots 634 distributed in a ring shape are provided at one end of the first connecting rod 63 away from the second connecting rod 64. A sliding tooth 621 is slidably clamped inside the connecting member 62. A third spring 622 is fixedly connected between the sliding tooth 621 and the connecting member 62. The third spring 622 is used to push the sliding tooth 621 to clamp the mating slots 634.

[0072] When the upper housing 61 is rotated, at this time the upper housing 61 will drive the connecting member 62 to rotate, and the sliding tooth 621 will clamp the mating slots 634 under the action of the third spring 622. Therefore, when the connecting member 62 rotates, the first connecting rod 63 will also be clamped. When the first connecting rod 63 is driven to rotate, at this time the first connecting rod 63 will move along the outside of the second threaded cylinder 641, thereby reducing the distance between the two second connecting rods 64. And the second connecting rods 64 are connected to the first fixing member 4 and the second fixing member 5, so that the distance between the first fixing member 4 and the second fixing member 5 can be changed. When the clamping force between the first fixing member 4 and the second fixing member 5 reaches the maximum, at this time the rotational resistance between the second threaded cylinder 641 and the first connecting rod 63 will also increase. Both the mating slots 634 and the sliding tooth 621 are conical. When the resistance exceeds the elastic force of the third spring 622, at this time the sliding tooth 621 is pushed and loses the clamping effect with the mating slots 634.

[0073] Therefore, by providing the connecting member 62, the device can prevent excessive clamping of the patient's head to avoid unnecessary damage to the patient, and can also adjust the direction of the upper housing 61, facilitating the change of the orientation of the suction tube 69, making it more convenient to fix the suction tube 69 and playing a supporting role.

[0074] As Figure 7 shown, a connecting rope 633 is fixedly installed at one end of the first central slide rod 632 away from the third threaded cylinder 642. The connecting rope 633 penetrates through the upper housing 61 and is rotatably installed on the corresponding connecting plate 613. A limiting housing 65 is fixedly installed at one end of the second connecting rod 64 away from the second threaded cylinder 641. A limiting block 651 is slidably clamped inside the limiting housing 65. A fourth spring 652 is fixedly connected between the limiting block 651 and the limiting housing 65. A plurality of limiting holes 653 corresponding to the clamping rods 53 are formed on the limiting block 651. A soft rope 643 is fixedly installed at one end of the third threaded cylinder 642 away from the first central slide rod 632. The soft rope 643 is movably clamped inside the second connecting rod 64. One end of the soft rope 643 away from the third threaded cylinder 642 penetrates through the limiting housing 65 and is fixedly connected to the limiting block 651. The two limiting housings 65 are respectively rotatably installed on the arc surfaces of the side fixing ring 51, the upper fixing ring 41, and the lower fixing ring 42.

[0075] When pressing the lower housing 611, at this time, the rising of the lower housing 611 will drive the connecting plate 613 to rise. Because the connecting plate 613 is inclined, when the connecting plate 613 rises, the upper end of the connecting plate 613 will slide along the linear chute 612, thereby pulling the connecting rope 633. When the connecting rope 633 is pulled, at this time, the connecting rope 633 drives the first central slide rod 632 to move, and the first central slide rod 632 will drive the third threaded cylinder 642 to move. When the third threaded cylinder 642 moves, it will pull the soft rope 643, and the soft rope 643 will exert a pulling force on the limiting block 651. At this time, the corresponding clamping rod 53 is released by the limiting hole 653. At this time, the tightening member 6 can rotate around the surfaces of the side fixing ring 51, the upper fixing ring 41, and the lower fixing ring 42. If the lower housing 611 is released, under the action of the second spring 614, the lower housing 611 resets, the connecting plate 613 is pulled back to its original position again, and under the action of the fourth spring 652, the limiting block 651 will also return to its original position. Furthermore, the limiting hole 653 will re-clamp the clamping rod 53.

[0076] By setting the connecting plate 613 in this device, it only needs to press the lower housing 611 to release the connection between the tightening member 6 and the second fixing member 5 and the first fixing member 4. When the lower housing 611 is released, it can re-fix the second fixing member 5 and the first fixing member 4, can conveniently adjust the position of the upper housing 61, more conveniently adjust the force application angle of the upper housing 61, prevent it from blocking the operation, and can also make it more convenient for the doctor to rotate the second fixing member 5 and the first fixing member 4.
