Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a neurosurgical dura mater suspension device. Background Technology

[0002] Dura mater suspension plays a crucial role in reducing epidural hematoma formation during neurosurgery. Intraoperative dura mater suspension effectively prevents separation from the inner table of the skull during exposure or traction, reducing ineffective cavity space within the surgical space and thus minimizing the possibility of postoperative blood exudation. Furthermore, dura mater suspension stabilizes dura mater tension, promotes close adhesion between the dura mater and the inner table of the skull, and improves the mechanical stability of the dura mater, thereby reducing the risk of epidural hematoma formation from the outset. Clinically, the dura mater is routinely sutured to the skull through a drill hole or to the external fascia, muscles, and other tissues. However, dura mater suspension is time-consuming, and in special circumstances, some damaged dura mater cannot be suspended. Additionally, sutures are not always secure, and postoperative suture breakage can lead to epidural hematoma. Therefore, a technical solution is urgently needed to address these issues.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] like Figures 1 to 6 As shown, this utility model provides a neurosurgical dura mater suspension device, including a fixed titanium clip 1, a medical clamp 6 for holding the fixed titanium clip 1 on the back, and a slot 61 for restricting the fixed titanium clip 1 at the end.

[0026] As a further embodiment of a neurosurgical dura mater suspension device, the fixation titanium clip is U-shaped.

[0027] As a further explanation of this embodiment, in the existing medical system, clinical practice routinely involves suturing the dura mater to the skull through a drill hole or to the external fascia, muscles, and other tissues. However, suspending the dura mater is time-consuming, and in special circumstances, some damaged dura mater cannot be suspended. Furthermore, the sutures are not always secure, and postoperative suture breakage may lead to epidural hematoma. In this embodiment, the titanium clip 1 is clamped and fixed by the slot 61 at the end of the medical clamp 6 (in this embodiment, the medical clamp is a general term for various surgical forceps used in surgery). The bottom end of the fixing titanium clip 1 pierces the edge of the dura mater, and the upper end of the fixing titanium clip 1 is placed on the outer plate of the skull. The dura mater is then suspended to the inner plate of the skull by fixing the titanium clip 1, thus completing the dura mater suspension surgery procedure.

[0028] Example 2

[0029] As a further embodiment of a neurosurgical dura mater suspension device, the fixed titanium clip 1 includes a mounting box 2, a first clamping plate 3, and a second clamping plate 4. Two guide posts 21 are fixedly installed inside the mounting box 2. The first clamping plate 3 and the second clamping plate 4 are slidably sleeved on the two guide posts 21. Each guide post 21 is sleeved with an upper spring 23 and a lower spring 24. The two ends of the upper spring 23 abut against the inner wall of the top of the mounting box 2 and the upper surface of the first clamping plate 3, respectively. The two ends of the lower spring 24 abut against the inner wall of the bottom of the mounting box 2 and the bottom of the second clamping plate 4, respectively. A connecting plate 22 is fixedly connected to one side of the first clamping plate 3 and the second clamping plate 4. The two connecting plates 22 are connected to the same auxiliary opening and closing component 5.

[0030] As a further explanation of this embodiment, in this embodiment, the fixation titanium clip 1 is opened using the medical clamp 6, one end of the fixation titanium clip 1 penetrates the edge of the dura mater, so that the dura mater is tightly attached to the inner table of the skull, and the other end is placed on the outer table of the skull. Releasing the medical clamp 6 releases the dura mater, thus fixing the dura mater to the skull, thereby completing the dura mater suspension. Specifically, the working principle of the fixation titanium clip 1 is as follows: the first clamp 3 and the second clamp 4 are brought closer together by the elastic force of the upper spring 23 and the lower spring 24. The medical clamp 6 moves the two connecting plates 22 to separate the first clamp 3 and the second clamp 4, inserts the second clamp 4 into the dura mater, and places the first clamp 3 on the outer plate of the skull, fixing and suspending the dura mater on the skull. The medical clamp 6 is then released, and the upper spring 23 and the lower spring 24 abut against the first clamp 3 and the second clamp 4, causing the second clamp 4, which penetrates the dura mater, to adhere to the inner plate of the skull, and the first clamp 3 to adhere to the outer plate of the skull, thereby fixing the dura mater to the inner plate of the skull to complete the dura mater suspension.

[0031] In addition, before using this device to suspend the dura mater, the fixation titanium clip 1 needs to be separated. However, conventional medical clamps 6 mostly use a scissor-type opening and closing mechanism. When using this type of medical clamp 6 to separate the fixation titanium clip 1, it places a significant burden on the medical staff using the medical clamp 6. Specifically, when using the medical clamp 6 to open the fixation titanium clip 1, the palm holding the medical clamp 6 needs to be spread open. Maintaining this open palm position for a long time during craniotomy can easily cause hand fatigue or even cramps. Moreover, this method of opening and closing the fixation titanium clip 1 makes it difficult to control the size of the opening of the fixation titanium clip 1. Therefore, an auxiliary opening and closing component 5 is added. The end of the medical clamp 6 is inserted into one end of the auxiliary opening and closing component 5, and the fixation titanium clip 1 is fixed to the other end of the auxiliary opening and closing component 5. This changes the way the medical clamp 6 opens and closes the fixation titanium clip 1, further improving the practicality of this device.

[0032] As a further embodiment of a neurosurgical dura mater suspension device, the auxiliary opening and closing assembly 5 includes a first hinge plate 51, a second hinge plate 52, a first hollow tube 53, a second hollow tube 54, a first limiting tube 55, and a second limiting tube 56. The bottom of the first hinge plate 51 and the top of the second hinge plate 52 are hinged to each other. The two ends of the first hinge plate 51 are rotatably connected to the first hollow tube 53 and the first limiting tube 55, respectively. The two ends of the second hinge plate 52 are rotatably connected to the second hollow tube 54 and the second limiting tube 56, respectively. One end of each of the two connecting plates 22 extends into the interior of the first hollow tube 53 and the second hollow tube 54, respectively, and the two connecting plates 22 are tangent to the sidewalls of the first hollow tube 53 and the second hollow tube 54, respectively. A top spring 57 is fixedly connected to the lower surface of the end of the first hinge plate 51 near the first limiting tube 55, and the bottom of the top spring 57 is fixedly connected to the upper surface of the second hinge plate 52.

[0033] As a further explanation of this embodiment, the working principle of the auxiliary opening and closing component 5 in this embodiment is as follows: the ends of the two connecting plates 22 are respectively inserted into the first hollow tube 53 and the second hollow tube 54, and the two ends of the medical clamp 6 are respectively inserted into the first limiting tube 55 and the second limiting tube 56, so that the medical clamp 6 and the fixing titanium clip 1 are respectively engaged with the two ends of the auxiliary opening and closing component 5. When the medical clamp 6 drives the first limiting tube 55 and the second limiting tube 56 to move closer to each other, the first hinge plate 51 and the second hinge plate 52 compress the top spring 57 and rotate around the hinge point, and The first hollow tube 53 and the second hollow tube 54 are rotatably connected to the first hinge plate 51 and the second hinge plate 52, respectively. Therefore, when the first limiting tube 55 and the second limiting tube 56 approach each other under the closing and pushing of the medical clamp 6, the first hollow tube 53 and the second hollow tube 54 move away from each other, thereby causing the first clamp plate 3 and the second clamp plate 4 to move away from each other, so that the fixed titanium card 1 is in the open state. After the fixed titanium card 1 completes the dura mater suspension operation, the auxiliary opening and closing component 5 is disengaged from the fixed titanium card 1 by the medical clamp 6, so that the fixed titanium card 1 remains at the patient's affected area.

[0034] As a further embodiment of a neurosurgical dura mater suspension device, the sidewalls of the first hollow tube 53 and the second hollow tube 54 are provided with a plurality of clearance grooves 58, and the sidewalls of the first limiting tube 55 and the second limiting tube 56 are provided with a plurality of insertion grooves 59.

[0035] As a further explanation of this embodiment, in this embodiment, multiple clearance grooves 58 and insertion grooves 59 are provided for the ends of the connecting plate 22 and the medical clamp 6 to insert into, respectively. The opening size of the multiple clearance grooves 58 is greater than or equal to the thickness of the end of the connecting plate 22, and the opening size of the multiple insertion grooves 59 is greater than or equal to the width of the end of the medical clamp 6. This design facilitates the entry and exit of the ends of the connecting plate 22 and the medical clamp 6.

[0036] As a further embodiment of a neurosurgical dura mater suspension device, a horizontal plate 221 is fixedly connected to the side wall of the connecting plate 22, and the horizontal plates 221 on the two connecting plates 22 extend into the clearance grooves 58 of the first hollow tube 53 and the second hollow tube 54, respectively.

[0037] As a further explanation of this embodiment, when the first hinge plate 51 and the second hinge plate 52 rotate, the connecting plate 22, under the elastic support of the upper spring 23 and the lower spring 24, pushes the horizontal plate 221 against the inner wall of the clearance groove 58, so that there is a large friction between the first hollow tube 53 and the second hollow tube and the connecting plate 22, so that the horizontal plate 221 will not detach from the first hollow tube 53 and the second hollow tube 54 when sliding with the first clamping plate 3 or the second clamping plate 4. Similarly, the end of the medical clamp 6 will not detach from the first limiting tube 55 and the second limiting tube 56 when clamped.

[0038] In addition, after the dura mater suspension operation of the fixed titanium clip 1 is completed, the medical clamp 6 is appropriately loosened, so that the elastic force generated by the deformation of the top spring 57 supports the rotation and reset of the first hinge plate 51 and the second hinge plate 52. After the fixed titanium clip 1 clamps the skull, the first clamp 3 and the second clamp 4 cannot continue to approach, so that the horizontal plate 221 loses the friction between the inner wall of the relief groove 58, while the end of the medical clamp 6 still has a large friction with the first limiting tube 55 and the second limiting tube 56. Therefore, the medical clamp 6 and the auxiliary opening and closing component 5 can be directly removed from the fixed titanium clip 1 after the operation, and the fixed titanium clip 1 is temporarily left at the patient's affected area.

[0039] As a further embodiment of a neurosurgical dura mater suspension device, a first limiting rod 531 is fixedly connected inside both the first hollow tube 53 and the second hollow tube 54.

[0040] As a further embodiment of a neurosurgical dura mater suspension device, a second limiting rod 551 is fixedly connected inside both the first limiting tube 55 and the second limiting tube 56.

[0041] As a further explanation of this embodiment, in order to prevent the horizontal plate 221 or the medical clamp 6 from extending too far into the auxiliary opening and closing assembly 5 and causing jamming when taking it out, a first limiting rod 531 and a second limiting rod 551 are provided to limit the insertion distance of the horizontal plate 221 and the medical clamp 6.

Any person skilled in the art can make some modifications or alterations to other equivalent embodiments without departing from the scope of the technical means disclosed in the present utility model, but these should still be regarded as the same technology or embodiment as the present utility model.
