Technical Field

[0001] The present invention belongs to the technical field of surgical craniotomy, and particularly relates to a medical device for surgical craniotomy. Background Art

[0002] Craniotomy is generally performed clinically in cases such as patients with craniocerebral injuries or the removal of brain tumors. Generally, during craniotomy, the patient's head needs to be fixed, and then a U-shaped incision is made in the scalp at the affected area. After cutting through the scalp, several holes are drilled in the skull, the bone flap is removed for intracranial surgery, and the skull is replaced and the wound is sutured after the medical operation.

[0003] However, when operating on the patient's head, the patient's head is usually difficult to be stably fixed and is prone to shaking, which affects the progress of the operation. Therefore, there is a current skull fixation frame that uses nails to pierce through the scalp and fix it on the healthy part of the skull, but this will exacerbate the patient's pain. Some patients often experience bleeding during the recovery period after craniotomy, and there are still three small holes on the head after recovery, and there is occasional discomfort. Therefore, there is a need for a medical device for surgical craniotomy. Summary of the Invention

[0006] With the above technical solution, when using medical devices for surgical craniotomy, the installation and fastening of the device to the operating table are preferably achieved through the adjustment component (7), and the angle and height are adjusted according to the usage requirements. This is an existing structure and will not be elaborated here. When it is necessary to fix the patient's head, the wound of the patient is preferably determined first, and then two appropriate head positions are selected, and the side support component (1) is controlled to adjust the position of the side adjustment component (2). The specific position fastening can be adjusted by the side adjustment component (2) itself. Among them, the adapter component (4) is used to contact and fasten the patient's chin, helping to fix the entire head of the patient in a three-point manner, and the contact fastening between the adapter component (4) and the chin can be further adjusted and changed. When the patient's wound is not in the center of the head, it is convenient for the adapter component (4) to adjust the adaptation of the chin fixation.

During the movement of the side plates (3011), the contact with the first connecting member (302) and the second connecting member (303) is achieved or cancelled. Among them, the third sliders (3015) and the second sliding grooves (3016) cooperate to guide the movement of the side plates (3011). When the side plates (3011) cancel the contact with the first connecting member (302) and the second connecting member (303), at this time, the first fitting members (3017) on one side of the first connecting member (302) and the second connecting member (303) and the second fitting members (3018) will be relaxed and there will be no situation of mutual interference and engagement. At this time, the position adjustment of the first connecting member (302) and the second connecting member (303) can be realized, and at the same time, the position of the housing (301) on the surfaces of the first connecting member (302) and the second connecting member (303) can also be changed, improving the adaptability of this structure and facilitating adjustment to meet the surgical requirements at different angles.

[0016] With the above technical solution, during the rotation of the fourth knob (407), the fourth screw (406) will move forward in the second fixing plate (404). At this time, the first fixing plate (403), the third connecting piece (401), and the second contact piece (402) will be driven to move, facilitating fastening adjustment for different users, increasing the flexibility of use, and the guide rods (405) cooperate with the movement of the first fixing plate (403) for guiding.

[0017] The present invention is further configured as follows: The installation component (5) includes a first disc (501). The first disc (501) is fixedly connected to the front side of the fitting (107). A second disc (502) is provided on one side of the first disc (501). Convex blocks (503) for mutual cooperation are fixedly installed on the opposite surfaces of the first disc (501) and the second disc (502). A fifth screw (504) penetrating through to the other side of the second disc (502) is fixedly installed on one side of the first disc (501). A fifth knob (505) in contact with the other side of the second disc (502) is threadedly connected to the surface of the fifth screw (504).

[0018] With the above technical solution, the angle between the first disc (501) and the second disc (502) will be limited and clamped and fixed through the convex blocks (503). Among them, through the rotation of the fifth knob (505), the movement forward on the surface of the fifth screw (504) will be realized. After the fifth knob (505) comes into contact with the second disc (502), the distance between the first disc (501) and the second disc (502) can be limited and fixed.

[0019] The present invention is further configured as follows: The rotating assembly (6) includes a first fixing block (601). The rear sides of the first fixing block (601) and the fitting (107) are fixedly connected to each other. A second fixing block (602) is fixedly installed at the bottom of the first fixing block (601). A rotating block (603) is fixedly installed at the bottom of the second fixing block (602). A worm (604) is rotatably connected to the inner side of the rotating block (603) through a bearing. One end of the worm (604) penetrates to the rear side of the rotating block (603) and a rotating knob (605) is fixedly installed. A worm gear (606) is meshed with the surface of the worm (604). A bottom block (607) is fixedly installed inside the worm gear (606). End plates (608) are fixedly installed at both ends of the bottom block (607). A second guiding member (609) is fixedly installed on one side of the end plate (608). A guiding groove (6010) is formed inside the second guiding member (609). Positioning rods (6011) penetrating to the bottom of the guiding groove (6010) are fixedly installed on both sides of the bottom of the rotating block (603). A limiting block (6012) is fixedly installed at the bottom of the positioning rod (6011). Indication marks (6013) are fixedly installed on the front side and the rear side of the rotating block (603). Scales (6014) are formed on the surface of the end plate (608).

[0020] With the above technical solution, during the rotation of the rotating knob (605), the worm (604) will be driven to rotate, while the worm gear (606) is fixed and immovable, thus realizing the movement trend of the worm (604) with the worm gear (606) as the center. At this time, the worm (604), the rotating block (603), the second fixing block (602) and the first fixing block (601) will all achieve angle adjustment, increasing the adaptability and compatibility in use and providing flexibility. Among them, during the adjustment of the rotating block (603), through the arrangement of the guiding groove (6010) and the positioning rod (6011), the rotation of the rotating block (603) will be guided. The limiting block (6012) prevents the positioning rod (6011) from slipping off, increasing the contact between the rotating block (603) and the end plate (608). During the rotation of the rotating block (603), the adjustment of the rotating block (603) can be viewed through the arrangement of the indication mark (6013) and the scale (6014).

[0021] The present invention is further configured as follows: The adjusting assembly (7) includes a cross bar (701). Both ends of the surface of the cross bar (701) are sleeved with a first sleeve block (702). Between the two first sleeve blocks (702), there is a second sleeve block (703) sleeved on the surface of the cross bar (701). At the bottom of both the first sleeve block (702) and the second sleeve block (703), there is a sixth screw (705) respectively penetrating into the inside of the first sleeve block (702) and the second sleeve block (703) and contacting the cross bar (701). At the bottom of the sixth screw (705), a sixth knob (704) is fixedly installed. The three sixth screws (705) are respectively threadedly connected with the first sleeve block (702) and the second sleeve block (703). At the bottom of the first sleeve block (702), a bottom bar (706) is fixedly installed.

[0022] With the above technical solution, when rotating the sixth knob (704) at the bottom of the first sleeve block (702), the position limit of the first sleeve block (702) will be realized through the contact between the sixth screw (705) and the cross bar (701). This structure can realize the movement adjustment of the first sleeve block (702) at different positions on the surface of the cross bar (701), helping the two bottom bars (706) to move closer or farther away, facilitating the adaptation and installation with different operating tables and increasing the use flexibility. At the same time, when rotating the sixth knob (704) at the bottom of the second sleeve block (703), the angle fixation of the second sleeve block (703) on the surface of the cross bar (701) will be realized through the contact between the sixth screw (705) and the cross bar (701). This structure can realize different angle adjustments of the second sleeve block (703) on the surface of the cross bar (701), increasing the use flexibility of this structure.

[0023] The present invention is further configured as follows: On one side of the bottom bar (706), an installation bar (707) is fixedly installed. On the top of the second sleeve block (703), a first vertical bar (708) is fixedly installed. On the top of the first vertical bar (708), a second vertical bar (709) and a third vertical bar (7010) are successively arranged. The third vertical bar (7010) is fixedly connected to the bottom block (607). At the bottom of both the third vertical bar (7010) and the second vertical bar (709), a first installation block (7011) is fixedly installed. At the top of both the first vertical bar (708) and the second vertical bar (709), a second installation block (7012) located outside the first installation block (7011) is fixedly installed. On one side of the second installation block (7012), there is a seventh screw (7014) penetrating through the first installation block (7011) to the other side of the second installation block (7012). On the surface of the seventh screw (7014), a seventh knob (7013) in contact with the second installation block (7012) is threadedly connected.

[0024] With the above technical solution, when the bottom rods (706) approach or move away from each other, the mounting rods (707) will be driven to be adaptively mounted with different operating tables, increasing the flexibility of use. At the same time, during the adjustment and fastening of the seventh screw (7014) and the seventh knob (7013), the angles between the first vertical rod (708) and the second vertical rod (709), and between the second vertical rod (709) and the third vertical rod (7010) can also be adjusted respectively. At the same time, the height of the upper contact member one (202) and the contact member two (402) can also be adjusted through the angle change.

[0025] In summary, the present invention has the following beneficial effects:

[0026] When using the medical device for surgical craniotomy, first determine the wound site of the patient, then select two appropriate cranial positions, and adjust the distance between the two contact members one (202) according to the size of the patient's head. Then, the contact and fastening of the patient's chin are achieved through the contact member two (402) to help fix the entire head of the patient in a three-point manner. At the same time, when the wound of the patient is not in the middle of the head, the position of the shell (301) can be changed to adaptively adjust the chin contact. The adaptability of this structure is increased, and this structure is different from the existing head fixation frame in that it can protect the patient's head from damage during use, ensure stability while reducing the patient's pain, and help the craniotomy proceed smoothly and stably;

[0027] When using the medical device for surgical craniotomy, the convenience of angle adjustment of this structure can be achieved by rotating the knob (605). During this adjustment process, different from the existing method of supporting the unfixed structure when loosening the fixing structure, it is necessary to hold the unfixed structure with one hand while making progressive changes in the angle, and at the same time, reinstall the fixing structure appropriately with the other hand. However, this structure can achieve angle adjustment by rotation, enabling the operator to operate easily with one hand. After adjusting to the appropriate position, release the force applied during rotation. This structure is convenient to operate and simple to use, bringing labor-saving and intuitive changes during adjustment to the operator. BRIEF DESCRIPTION OF THE DRAWINGS

The side support assembly 1 includes a first support member 101 and a second support member 102. One end of the first support member 101 is fixedly installed with a fitting member 107. One end of the second support member 102 penetrates through the fitting member 107 into the interior of the first support member 101. A fitting groove 103 is formed at the top of the second support member 102. Fitting protrusions 104 are fixedly installed at the top of both the fitting member 107 and the interior of the first support member 101. Side adjustment assemblies 2 are provided at the tops of both the first support member 101 and the second support member 102. A moving assembly 3 is provided between the first support member 101 and the second support member 102. An adaptation assembly 4 is provided at the top of the moving assembly 3. An installation assembly 5 is provided on one side of the fitting member 107. A rotating assembly 6 is provided on the other side of the fitting member 107. An adjustment assembly 7 is provided at the bottom of the rotating assembly 6. When using the medical device for surgical craniotomy, first determine the wound location of the patient, then select two appropriate cranial positions, and control the side support assembly 1 to adjust the position of the side adjustment assembly 2. Among them, the adaptation assembly 4 contacts and fastens the patient's chin to help fix the entire head of the patient in a three-point manner. When the patient's wound is not in the center of the head, it is convenient for the adaptation assembly 4 to adjust the adaptation for fixing the chin. The adaptability of the structure is increased, and the structure is different from the existing head fixing frame in terms of the damage to the patient's skull during use, which can ensure stability while reducing the pain of the patient and help the craniotomy proceed smoothly and steadily. And during the use of this structure, the convenience of angle adjustment of the structure can be achieved through the rotating assembly 6. During this adjustment process, different from the existing situation of supporting the unfixed structure when loosening the fixing structure, it is necessary to hold the unfixed structure with one hand while making progressive changes in the angle, and at the same time reinstall the fixing structure appropriately with the other hand. However, this structure can achieve angle adjustment by rotation, enabling the operator to operate easily with one hand. After adjusting to the appropriate position, release the force applied to the rotation.

[0064] Brief description of the usage process: When using medical devices for surgical craniotomy, first install and fasten the device to the operating table through the installation rod 707, and adjust the angle and height according to the usage requirements. This is an existing structure and will not be elaborated here. When it is necessary to fix the patient's head, first determine the wound area of the patient, then select two appropriate head positions, and adjust the distance between the two contact members 202 according to the size of the patient's head. Insert the first support member 101 deeper into the second support member 102, which can make the two contact members 202 approach each other. The mutual cooperation of the fitting convex block 104 and the fitting groove 103 helps to fix and limit the second support member 102, and it is a one-way progression, which is convenient for fastening the patient's head. The rotation of the first knob 106 will cause the first screw 105 to move forward inside the fitting member 107, thereby realizing the contact limit of the second support member 102. Then, by rotating the second knob 205, the second screw 203 will be driven to rotate, thereby realizing the movement of the contact member 202, and the setting of the connecting block 204 will ensure that the second screw 203 will not affect the contact angle between the contact member 202 and the head. At this time, first determine the two fixed points of the head, and the specific fastening of the contact member 202 can be realized through the first knob 106. The first connecting member 302 and the second connecting member 303 can change their positions inside the housing 301 by the approach of the first support member 101 and the second support member 102. First, rotate the third knob 307, which will cause the third screw 306 to drive the threaded block 305 and the bottom plate 304 to change their positions inside the housing 301. The first sliding groove 3010 respectively cooperates with the first slider 308 and the second slider 309 for moving guidance. During the movement of the threaded block 305 and the bottom plate 304, the position change of the side plate 3011 will be realized through the setting of the first guiding member 3013 and the through groove 3014. The side plate 3011 will contact or cancel the contact with the first connecting member 302 and the second connecting member 303 during the movement. The third slider 3015 and the second sliding groove 3016 cooperate with the side plate 3011 for moving guidance. When the side plate 3011 cancels the contact with the first connecting member 302 and the second connecting member 303, the first fitting member 3017 and the second fitting member 3018 on one side of the first connecting member 302 and the second connecting member 303 will be relaxed and will not be mutually affected and clamped. At this time, the position adjustment of the first connecting member 302 and the second connecting member 303 can be realized, and at the same time, the position of the housing 301 on the surfaces of the first connecting member 302 and the second connecting member 303 can also be changed, improving the adaptability of the structure and facilitating adjustment to meet the surgical requirements at different angles. When the side plate 3011 realizes the contact with the first connecting member 302 and the second connecting member 303, the first fitting member 3017 and the second fitting member 3018 on one side of the first connecting member 302 and the second connecting member 303 will be mutually clamped, and the positional relationship among the housing 301, the first connecting member 302 and the second connecting member 303 will be fixed.At this time, the contact and fastening of the patient's chin will be achieved through the second contact member 402 to help fix the entire head of the patient in a three-point manner. And through the rotation of the fourth knob 407, the movement and progression of the fourth screw 406 in the second fixing plate 404 will be realized. At this time, it will drive the first fixing plate 403, the third connecting member 401 and the second contact member 402 to move, which is convenient for fastening adjustment and use with different users, increasing the flexibility of use. And the guide rod 405 cooperates with the movement of the first fixing plate 403 for guiding. At the same time, when the wound of the patient is not in the center of the head, the adaptability adjustment of the chin contact can be carried out through the position change of the housing 301. The adaptability of the structure in use is increased, and the structure is different from the existing head fixing frame in damaging the patient's skull during use. It can ensure the stability while reducing the pain of the patient, and help the craniotomy to proceed smoothly. And during the use of this structure, the worm 604 can be driven to rotate by rotating the knob 605, while the worm gear 606 is fixed and immovable, so as to realize the movement trend of the worm 604 around the worm gear 606 as the center. At this time, the worm 604, the rotating block 603, the second fixing block 602 and the first fixing block 601 will all realize angle adjustment, increasing the adaptability and compatibility in use and providing flexibility. Among them, during the adjustment of the rotating block 603, through the settings of the guide groove 6010 and the positioning rod 6011, the rotation guidance of the rotating block 603 will be cooperated, and the limiting block 6012 prevents the positioning rod 6011 from slipping off, increasing the contact between the rotating block 603 and the end plate 608. During the rotation of the rotating block 603, the adjustment and viewing of the rotating block 603 will be realized through the settings of the indicating mark 6013 and the scale 6014. The convenience of the angle adjustment of this structure is realized. During this adjustment process, different from the existing situation of supporting the unfixed structure when loosening the fixing structure, it is necessary to hold the unfixed structure with one hand while making progressive changes in the angle, and at the same time, reinstall the fixing structure appropriately with the other hand. And this structure can realize the angle adjustment by rotation, enabling the operator to perform easy single-handed operation. After adjusting to the appropriate position, just release the force applied during rotation. This structure is convenient to operate and simple to use, bringing labor-saving and intuitive changes during adjustment to the operator.
