[0002] Hematoma evacuation in patients with intracerebral hemorrhage is a complex process, and the choice of method depends on many factors, including the amount of bleeding, the site of bleeding, the age and general condition of the patient, and the time from surgery to bleeding.

[0003] Common methods of hematoma removal for patients with cerebral hemorrhage include craniotomy hematoma removal, burr hole hematoma cavity drainage, neuroendoscopic surgery, and directional hematoma aspiration. Among them, craniotomy hematoma removal is a traditional surgical method suitable for critically ill patients with large hematomas or brain herniation.

[0004] Craniotomy is a surgical procedure that opens the skull and removes intracranial hematomas to reduce intracranial pressure, stop bleeding, and restore brain tissue function. This type of surgery is usually used for intracranial hematomas caused by brain trauma, cerebral hemorrhage, etc., and includes methods such as craniotomy with bone flap formation and craniotomy with bone window resection under the temporalis muscle for decompression. During the operation, precise operations are required under a microscope to reduce damage to normal brain tissue.

[0005] During the traditional craniotomy and hematoma removal surgery, multiple medical staff are needed to fix and support the patient's head, and hold the suction tube to prevent the tube from rubbing against the patient's brain.

There is no need for a lot of medical staff to provide support, and the situation of the pipeline scratching the patient's injured part is prevented. The doctor can focus his attention completely on the patient, thereby improving the safety of the operation, reducing the personnel requirements, and improving the convenience of using the device.

[0031] By setting a lower anti-detachment shell, when the bandage is completed, the lower anti-detachment shell can be slid to the top of the suction tube, and then the protrusion and the card groove on the locking flap are engaged with each other, and then the lower anti-detachment shell is rotated at this time, the length of the lower anti-detachment shell and the first threaded tube increases, until the lower anti-detachment shell is against the patient's head, and the protrusion is against the locking flap, at this time, the suction tube outside the patient's body can be fixed, preventing the suction tube from shaking or even slipping, and preventing the patient from recovering and getting infected in the later stage due to shaking

[0032] By providing a tightening member and a movable frame, the device can be adapted to people with different head lengths, can produce a better clamping effect, and improve the stability of the device.

[0033] By setting up the upper matching plate and the lower matching plate, when using it, the doctor only needs to rotate the tightening part to drive the first fixing part and the second fixing part to rotate to change the direction of the patient's head, and it can be automatically stuck to prevent movement by simply letting go, which reduces the tediousness of use and makes it more convenient to use.

[0034] By providing a connecting piece, it is possible to prevent excessive clamping of the patient's head to prevent unnecessary damage to the patient, and the direction of the upper shell can be adjusted to facilitate changing the orientation of the suction tube, making it more convenient to fix the suction tube and play a supporting role.

[0035] By setting up the connecting plate, it is only necessary to press the lower shell to release the connection between the tightening part and the second fixing part and the first fixing part. When the lower shell is loosened, the second fixing part and the first fixing part can be fixed again. The position of the upper shell can be easily adjusted, and the force angle of the upper shell can be more easily adjusted to prevent it from blocking the operation, and it can also make it easier for the doctor to rotate the second fixing part and the first fixing part.

[0058] like Figures 1 to 12As shown, 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 mobile frames 3 are arranged on the rotating ring 2, the mobile frame 3 includes a support rod 31, the support rod 31 is arc-shaped, and the two mobile frames 3 are respectively provided with a first fixing component 4 and a second fixing component 5, 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 provided between the first fixing component 4 and the second fixing component 5, the tightening member 6 includes an upper shell 61, both sides of the upper shell 61 are fixedly installed with connecting members 62, and both sides of the upper shell 61 corresponding to the connecting member 62 are rotatably installed with a first connecting rod 63 The connecting piece 62 is sleeved on the outside of the first connecting rod 63, and a second connecting rod 64 is provided on the side away from each other of the two first connecting rods 63. A second threaded tube 641 is fixedly installed on the end of the second connecting rod 64 close to the first connecting rod 63, and a threaded groove 631 adapted to the second threaded tube 641 is opened on 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 shell 61 adjacent to the connecting piece 62, and two symmetrical locking flaps 67 are slidably installed on the guide rail 66. A suction tube 69 for sucking cerebral hematoma is provided below the two locking flaps 67, and a connecting tube 691 for connecting the input end of the drainage pump is provided above the two locking flaps 67. The outer sliding sleeve of the suction tube 69 is provided with a lower anti-detachment shell 70.

[0059] Before actual use, the patient is first given general anesthesia, and then the first fixing component 4 and the second fixing component 5 are removed from the support rod 31, and then the second fixing component 5 is placed at the top of the patient's skull, and the first fixing component 4 is put on the patient's neck. Then, the upper shell 61 is rotated at this time, and the upper shell 61 drives the connecting member 62 to rotate, and the rotation of the connecting member 62 drives the first connecting rod 63 to rotate. When the first connecting rod 63 rotates, the length of the second threaded tube 641 and the first connecting rod 63 is shortened, thereby changing the distance between the first fixing component 4 and the second fixing component 5, until the first fixing component 4 and the second fixing component 5 clamp the patient's head. Then, let the patient lie flat at this time and place the first fixing component 4 and the second fixing component 5 on the corresponding support rod 31, and the support rod 31 plays a role in the first fixing component 4 and the second fixing component 5. Supporting function, adjust the distance between the two support rods 31 to adapt to the first fixing part 4 and the second fixing part 5. At this time, the patient's head is supported by the support rod 31. The doctor can drive the first fixing part 4 and the second fixing part 5 to rotate on the surface of the support rod 31 by pushing the tightening part 6. The support rod 31 is set to an arc shape to better fit the rotation of the human head. When it rotates to the required position, the first fixing part 4 and the second fixing part 5 can stop automatically. At this time, the doctor opens a question mark-shaped incision in the patient's wound, then lifts the patient's scalp, uses a skull drill to drill, and then uses a milling cutter to cut along the drilled position. After the cutting is completed, the skull is moved away, and the doctor holds the lower anti-detachment shell 70 and slides and moves along the suction tube 69 without touching the suction tube 69. Then turn on the drainage pump, and the suction tube 69 can remove the congestion and blood clots at the patient's hematoma position.

[0060] After the cleaning is completed, the lower anti-detachment shell 70 is slid back to the top of the suction tube 69, and then the lower end of the suction tube 69 is left at the patient's hematoma position, and then the patient's skull is re-fixed with a fixing pin, and then the patient's scalp is re-sutured, and then the incision is bandaged. Because the locking flap 67 clamps the suction tube 69 during the dredging process, the doctor does not need to hold the tube.

[0061] By providing the first fixing component 4, the second fixing component 5, and the tightening component 6, the present device enables the doctor to operate on the patient's head more conveniently during craniotomy and hematoma removal surgery, reduces the need for personnel, does not require a lot of medical staff for support, and prevents the pipe from scratching the patient's injured part, allowing the doctor to focus completely on the patient, thereby improving the safety of the surgery, reducing the need for personnel, and improving the convenience of using the device.

[0062] like Figures 3 to 5As shown, the ends of the suction tube 69 and the connecting tube 691 close to each other are fixedly installed with a limit ring 692, and the two limit rings 692 are located between the two locking petals 67. A locking screw 68 is installed on the guide rail 66 through threaded cooperation. One end of the locking screw 68 is rotatably installed on the side surface of the corresponding locking petal 67. An upper anti-detachment shell 71 is provided above the lower anti-detachment shell 70. A first threaded barrel 72 is fixedly installed on the lower surface of the upper anti-detachment shell 71. The first threaded barrel 72 is clamped on the lower anti-detachment shell 70 through threaded cooperation. Inside the anti-detachment shell 70, the lower anti-detachment shell 70, the upper anti-detachment shell 71, and the first threaded cylinder 72 are all slidably mounted on the outer surface of the suction tube 69, and a plurality of evenly distributed protrusions 73 are fixedly mounted on the upper surface of the upper anti-detachment shell 71. A plurality of card grooves adapted to the protrusions 73 are provided on the lower surface of the locking petal 67. When in use, the distance between the two locking petals 67 can be changed by rotating the locking screw 68, thereby clamping or releasing the limit ring 692, and the guide rail 66 is used to keep the locking petal 67 sliding stably.

[0063] When the bandaging is completed, the lower anti-detachment shell 70 can be slid to the top of the suction tube 69, and then the protrusion 73 and the slot on the locking flap 67 are engaged with each other. Then the lower anti-detachment shell 70 is rotated, and the length of the lower anti-detachment shell 70 and the first threaded tube 72 increases until the lower anti-detachment shell 70 is against the patient's head and the protrusion 73 is against the locking flap 67. At this time, the suction tube 69 outside the patient's body can be fixed to prevent the suction tube 69 from shaking or even slipping, and to prevent the patient from getting infected during the later recovery due to shaking.

[0064] like Fig.12 As shown, the first fixing component 4 includes an upper fixing ring 41 and a lower fixing ring 42 which are symmetrical to each other, and the second fixing component 5 includes a side fixing ring 51.

The second baffle 55 and the first baffle 43 can clamp the two support rods 31 for fixing the positions of the second fixing component 5 and the first fixing component 4, and the second baffle 55 and the first baffle 43 are fixedly installed with a boss 52 on one side close to each other, and a plurality of evenly distributed clamping rods 53 are fixedly installed on one side close to each other of the two bosses 52, and the boss 52 plays a supporting role to prevent the clamping rods 53 from being subjected to force, and a block 54 is fixedly installed on the middle part of the side fixing ring 51 through a bracket, the upper fixing ring 41 and the lower fixing ring 42 are detachably spliced, and the upper fixing ring 41 and the lower fixing ring 42 are fixedly installed with a cushion 44 on one side close to the second fixing component 5.

[0065] When fixing, the upper fixing ring 41 and the lower fixing ring 42 are disassembled, and then the upper fixing ring 41 and the lower fixing ring 42 are put on the patient's neck position, and then the upper fixing ring 41 and the lower fixing ring 42 are fixed, and the stopper 54 is placed at the patient's skull top position, and then the upper shell 61 is rotated to drive the first fixing component 4 and the second fixing component 5 to approach each other, the stopper 54 can support the patient's skull top, and the upper fixing ring 41 and the lower fixing ring 42 can support the patient's lower jaw, and the cushion 44 can prevent damage to the patient's lower jaw during clamping.

[0066] like Figure 2 As 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 slide rod 33, the upper surface of the rotating ring 2 is provided with a plurality of first slide grooves 21 corresponding to the first slide rod 33, the first slide rod 33 is slidably clamped inside the corresponding first slide grooves 21, a locking bolt 34 is installed on the extension rod 32 through threaded cooperation, and 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] When in 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, thereby ensuring 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. Then, by setting a tightening member 6 and a movable frame 3, the device can be adapted to people with different head lengths, can produce a better clamping effect, and improve the stability of the device.

[0068] like 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 an upper matching plate 57 and a lower matching plate 58, the device allows the doctor to change the orientation of the patient's head only by rotating the tightening member 6 to drive the first fixing member 4 and the second fixing member 5 to rotate when in use, and the device can be automatically locked to prevent movement by simply letting go, thereby reducing the complexity of use and making it more convenient to use.

[0071] like Figure 5 As shown, the lower end of the upper shell 61 is slidably clamped with a lower shell 611, a second spring 614 is fixedly connected between the upper shell 61 and the lower shell 611, and connecting plates 613 are rotatably installed at both ends of the upper surface of the lower shell 611. A symmetrical linear slide groove 612 is opened at the upper end of the inner side wall of the upper shell 61. The upper end of the connecting plate 613 is slidably clamped inside the linear slide groove 612. The connecting plate 613 is inclined. The end of the first connecting rod 63 away from the threaded groove 631 is slidably clamped with a first central slide rod 632, and the second The internal sliding card of the connecting rod 64 is provided with a third threaded cylinder 642, and the end of the first center sliding rod 632 close to the third threaded cylinder 642 is clamped in the inside of the third threaded cylinder 642 through threaded cooperation, and the end of the first connecting rod 63 away from the second connecting rod 64 is provided with a plurality of matching grooves 634 distributed in an annular shape, and the internal sliding card of the connecting member 62 is provided with a sliding tooth 621, and a third spring 622 is fixedly connected between the sliding tooth 621 and the connecting member 62, and the third spring 622 is used to push the sliding tooth 621 to clamp the matching groove 634.

[0072] When the upper shell 61 is rotated, the upper shell 61 will drive the connecting member 62 to rotate, and the sliding tooth 621 will clamp the matching groove 634 under the action of the third spring 622, and then 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, 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 rod 64 is connected to the first fixing component 4 and the second fixing component 5, thereby being able to change the distance between the first fixing component 4 and the second fixing component 5. When the clamping force of the first fixing component 4 and the second fixing component 5 reaches the maximum, the rotation resistance between the second threaded cylinder 641 and the first connecting rod 63 will also increase. The matching groove 634 and the sliding tooth 621 are both conical. When the resistance exceeds the elastic force of the third spring 622, the sliding tooth 621 is pushed to lose the clamping effect with the matching groove 634.

[0073] Therefore, the device is provided with a connecting piece 62 so as to prevent excessive clamping of the patient's head to prevent unnecessary damage to the patient, and can also adjust the direction of the upper shell 61 to facilitate changing the orientation of the suction tube 69, making it more convenient to fix the suction tube 69 and to play a supporting role.

[0074] like Figure 7 As shown, a connecting rope 633 is fixedly installed at one end of the first central sliding rod 632 away from the third threaded tube 642, and the connecting rope 633 passes through the upper shell body 61 and is rotatably installed on the corresponding connecting plate 613; a limiting shell 65 is fixedly installed at one end of the second connecting rod 64 away from the second threaded tube 641; a limiting block 651 is provided inside the limiting shell 65 for sliding clamping; a fourth spring 652 is fixedly connected between the limiting block 651 and the limiting shell 65; a plurality of limiting holes 653 corresponding to the clamping rod 53 are opened on the limiting block 651; a soft rope 643 is fixedly installed at one end of the third threaded tube 642 away from the first central sliding 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 tube 642 passes through the limiting shell 65 and is fixedly connected to the limiting block 651; the two limiting shells 65 are rotatably installed on the arc surfaces of the side fixing ring 51 and the upper fixing ring 41 and the lower fixing ring 42, respectively.

[0075] When the lower shell 611 is pressed, the lower shell 611 rises and drives the connecting plate 613 to rise. Because the connecting plate 613 is inclined, the upper end of the connecting plate 613 slides along the linear slide groove 612 when the connecting plate 613 rises, thereby pulling the connecting rope 633. When the connecting rope 633 is pulled, the connecting rope 633 drives the first center slide bar 632 to move, and the first center slide bar 632 drives the third threaded cylinder 642 to move. When the third threaded cylinder 642 moves, it pulls The soft rope 643 will pull the limit block 651, and the limit hole 653 will release the corresponding clamping rod 53. At this time, the tightening member 6 can rotate around the surface of the side fixing ring 51 and the upper fixing ring 41 and the lower fixing ring 42. If the lower shell 611 is loosened, the lower shell 611 will be reset under the action of the second spring 614, and the connecting plate 613 will be pulled back to its original position. The limit block 651 will also return to its original position under the action of the fourth spring 652, and then the limit hole 653 will clamp the clamping rod 53 again.

[0076] The device is provided with a connecting plate 613, so that it only needs to press the lower shell 611 to release the connection between the tightening member 6 and the second fixing component 5 and the first fixing component 4. When the lower shell 611 is loosened, the second fixing component 5 and the first fixing component 4 can be fixed again, and the position of the upper shell 61 can be easily adjusted, and the force angle of the upper shell 61 can be more easily adjusted to prevent it from blocking the operation, and it can also make it easier for the doctor to rotate the second fixing component 5 and the first fixing component 4.
