Description

Technical Field

[0001] This invention relates to the field of neurosurgical craniotomy technology, specifically a craniotomy device for neurosurgery. Background Technology

[0002] In neurosurgical practice, conditions such as acute intracranial hemorrhage drainage, intracranial pressure monitoring probe implantation, and intracranial tumor biopsy are often treated by establishing intracranial access through single-port burr hole surgery to achieve therapeutic or diagnostic goals. The core objective of single-port burr hole surgery is to quickly establish a precise access while minimizing surgical trauma, making it particularly suitable for emergency resuscitation and minimally invasive treatment scenarios. In such scenarios, the surgical procedure needs to be efficient and quick, while avoiding secondary damage caused by contamination and heat accumulation through a single incision.

[0003] During single-port craniotomy, the drill bit is in continuous single-point contact with the skull. The intense friction between the cutting edge and the bone tissue causes a large amount of heat to accumulate rapidly. In existing technologies, although cooling can be achieved through precise drip irrigation with sterile saline, i.e., by using a micro-drip irrigation tube to precisely drip sterile saline onto the contact area between the drill bit and the skull, which removes some heat while preventing water diffusion, this method has obvious limitations. It not only requires the cooperation of additional medical staff, but also requires a lot of pre-operative preparation work such as drip tube placement and flow rate adjustment. The operation process is cumbersome and difficult to meet the core requirement of single-port craniotomy, especially in emergency scenarios where the core need is to quickly establish intracranial access. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a skull drilling device for neurosurgery.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a skull drilling device for neurosurgery, including a skull drilling gun, a handle fixedly connected to the bottom end of the skull drilling gun, and a push-button switch fixedly installed on the handle; The skull drill is equipped with a pretreatment mechanism, which includes a moving ring and a transmission ring. A support base is fixedly connected to the bottom end of the moving ring. A pressing rod is fixedly connected to one side of the support base, and a spring is fixedly connected to one side of the support base. A support rod is fixedly connected to the other side of the support base. A support ring is fixedly connected to the top end of the support rod. A rotating ring is rotatably connected to the inner ring of the support ring. A threaded groove is formed on the inner surface of the rotating ring. A pressure seat is fixedly connected to the top end of the rotating ring. A loading ring is threadedly connected to the rotating ring through the threaded groove. A receiving cavity is formed inside the loading ring. The receiving cavity is filled with medical mineral oil. Multiple passage grooves are formed on the loading ring. A sponge ring is fixedly connected to the inner ring of the loading ring. The inner ring of the transmission ring is provided with a directional extrusion groove.

[0006] Specifically, the handle is fixedly attached at an angle to the bottom of the skull drill near the side, and the push-button switch is electrically connected to the skull drill via a cable.

[0007] Specifically, the movable ring is slidably connected to the drill gun near the side end, the transmission ring is fixedly connected to the side end of the drill gun, and one side of the rotating ring is located inside the transmission ring.

[0008] Specifically, the pressing rod and the pressing switch are on the same horizontal line, the pressing rod and the pressing switch have a certain distance, the spring is located on one side of the support base corresponding to the top of the pressing rod, and the other side of the spring is fixedly connected to the side wall of the handle.

[0009] Specifically, the diameter of the support ring is smaller than the diameter of the transmission ring, and the top of the pressure seat is hemispherical, with the hemispherical position of the top of the pressure seat movably abutting against the inside of the rotary extrusion groove.

[0010] Specifically, one end of each passage groove abuts against the outer wall of the sponge ring, and each passage groove is in communication with the receiving cavity. The top of the loading ring is fixedly connected to a feed port, and the feed port is in communication with the loading ring.

[0011] The beneficial effects of this invention are: This invention utilizes a pretreatment mechanism with a loading ring, a sponge ring, and medical mineral oil to uniformly apply mineral oil to the drill bit surface before drilling, forming an oil film. This reduces frictional heat generation between the drill bit and the skull, and also quickly conducts the generated heat, maintaining the temperature of the drill bit and skull surface within a safe range. This prevents burns to the periosteum, soft tissue, and intracranial tissue, while also preventing bone degeneration and necrosis around the drill hole, ensuring the stability of subsequent skull repair. The pretreatment mechanism and the drill start-up action are integrated and linked. The surgeon only needs to inject medical mineral oil into the receiving cavity of the loading ring before the operation. Afterwards, the surgeon only needs to push the support seat to simultaneously complete the uniform oiling and lubrication of the drill bit and the instrument start-up preparation. There is no need to carry out a series of additional operations related to drill bit cooling, which greatly simplifies the preoperative process. Compared with the existing drill guns that require additional cumbersome steps such as drip irrigation for cooling, this device not only significantly shortens the preoperative preparation and intraoperative operation time, but also avoids the operation interference that may be caused by the cooperation of extra staff, effectively reducing the operator's operation intensity. This design meets the core need of rapidly establishing intracranial access in emergency rescue scenarios and specifically improves the problems of time-consuming operation of traditional instruments and insufficient adaptability to high-efficiency scenarios such as emergency. The oil film formed by medical mineral oil can effectively wrap some of the bone fragments generated during drilling, preventing a large amount of fragments from splashing or adhering to the drill bit and surgical area during the craniotomy. At the same time, it reduces mechanical wear and thermal damage to the cutting edge, significantly extending the service life of the drill bit. In addition, when the pretreatment mechanism is reset under the action of the spring, the sponge ring will wipe the surface of the drill bit simultaneously, which can remove the bone fragments remaining on the drill bit, further ensuring the accuracy of the craniotomy operation and the cleanliness of the surgical area.

[0015] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0016] Please see Figures 1 to 6 The present invention provides the following technical solutions: Example 1: A skull drill device for neurosurgery includes a skull drill gun 1, a handle 2 fixedly connected to the bottom end of the skull drill gun 1, a push-button switch 3 fixedly installed on the handle 2, the handle 2 being fixedly connected at an angle to the bottom end of the skull drill gun 1 near the side end, and the push-button switch 3 being electrically connected to the skull drill gun 1 via a cable. When in use, the entire skull drill gun 1 can be held by the handle 2. The sterile drill bit of the skull drill gun 1 is aligned with the position of the patient's skull where a hole needs to be drilled. Then, the push-button switch 3 is pressed. At this time, the push-button switch 3 will start the skull drill gun 1 through the cable. The drill bit end of the skull drill gun 1 will rotate at high speed to open a hole in the patient's skull, thereby completing the drilling work.

[0017] Example 2: The skull drill 1 is equipped with a pretreatment mechanism 4, which includes a moving ring 41 and a transmission ring 42. The bottom end of the moving ring 41 is fixedly connected to a support base 43. A pressing rod 44 is fixedly connected to one side of the support base 43, and a spring 45 is fixedly connected to one side of the support base 43. A support rod 46 is fixedly connected to the other side of the support base 43. A support ring 47 is fixedly connected to the top end of the support rod 46. A rotating ring 48 is rotatably connected to the inner ring of the support ring 47. A threaded groove 49 is opened on the inner surface of the rotating ring 48. A pressure seat 50 is fixedly connected to the top end of the rotating ring 48. A loading ring 51 is threadedly connected to the rotating ring 48 through the threaded groove 49. A receiving cavity 52 is opened inside the loading ring 51. The receiving cavity 52 is filled with medical mineral oil 53. Multiple passage grooves 54 are opened on the loading ring 51. A sponge ring 55 is fixedly connected to the inner ring of the loading ring 51. A rotational extrusion groove 56 is opened on the inner ring of the transmission ring 42. The moving ring 41 is slidably connected to the drill gun 1 near the side end. The transmission ring 42 is fixedly connected to the side end of the drill gun 1. One side of the rotating ring 48 is located inside the transmission ring 42. The pressing rod 44 and the pressing switch 3 are on the same horizontal line and have a certain distance. The spring 45 is located on one side of the support seat 43 corresponding to the top of the pressing rod 44. The other side of the spring 45 is fixedly connected to the side wall of the handle 2. The diameter of the support ring 47 is smaller than the diameter of the transmission ring 42. The top of the pressure seat 50 is hemispherical. The hemispherical position of the top of the pressure seat 50 is movably abutted against the inside of the rotary extrusion groove 56. One end of the passage groove 54 abuts against the outer wall of the sponge ring 55. The passage groove 54 is in a state of communication with the receiving cavity 52. ​​The top of the loading ring 51 is fixedly connected to the feed port, and the feed port is in a state of communication with the loading ring 51. During use, it must be operated in a sterile environment to prevent contamination of the sterile drill bit of the skull drill 1 and the sponge ring 55. Open the feed port at the top of the loading ring 51, and then fill the internal receiving cavity 52 of the loading ring 51 with medical mineral oil 53 through the feed port. After filling, the operator can shake the entire loading ring 51 back and forth. At this time, the medical mineral oil 53 inside the receiving cavity 52 will flow to the sponge ring 55 through the passage groove 54, thus slowly soaking the entire sponge ring 55. Then connect the loading ring 51 to the rotating ring 48 through the threaded groove 49. The moving ring 48 can drive the loading ring 51 to move and rotate. Then, the finger loops around the support seat 43 and moves the support seat 43 towards the handle 2. The moving support seat 43 will drive the moving ring 41 to move on the drill gun 1. At the same time, the movement of the support seat 43 will also compress and contract the spring 45. The movement of the support seat 43 will also drive the pressing rod 44 to move towards the pressing switch 3. In addition, the movement of the support seat 43 will also drive the support rod 46 to move towards the handle 2. The movement of the support rod 46 will drive the support ring 47 to move. The movement of the support ring 47 will drive the rotation. As ring 48 moves, it drives the pressure seat 50, the loading ring 51, and the sponge ring 55 to move. During this movement, the pressure seat 50 is compressed by the spiral extrusion groove 56, causing it to rotate along the groove. This movement and rotation of the pressure seat 50 drives the rotating ring 48 to rotate as well. The loading ring 51 and the sponge ring 55, also moved by the rotating ring 48, will perform the same action. The moving and rotating sponge ring 55 will then be fitted onto the drill bit of the drill gun 1. On the head, the sponge ring 55, soaked with medical mineral oil 53, will evenly and thoroughly coat the surface of the drill bit with the medical mineral oil 53. Simultaneously, as the loading ring 51 rotates, the medical mineral oil 53 inside its receiving cavity 52 will flow again through the passage groove 54 onto the sponge ring 55. When the rotating ring 48 moves to the later stage, the gap between the pressing rod 44 on the support base 43 and the pressing switch 3 is very small. At this time, the drill bit of the skull drill 1 is also in the protruding state. In this state, the pretreatment mechanism 4 will not obstruct the operator's view, ensuring that the skull drilling operation is unaffected. Figure 6Then, the drill bit of the craniotomy gun 1 can be aligned with the location on the patient's skull where an opening is needed. Next, the support base 43 is pushed again, causing the support base 43 to move the pressing rod 44. The moving pressing rod 44 presses the push-button switch 3, and the craniotomy gun 1 is activated, ready to begin the craniotomy. The pretreatment mechanism 4 and the craniotomy activation are integrated, significantly shortening preoperative preparation and intraoperative operation time, avoiding operational interference that might arise from additional staff, effectively reducing the surgeon's workload, and specifically addressing the problems of time-consuming operation and insufficient adaptability to high-efficiency scenarios such as emergency situations. Because the drill bit of the craniotomy gun 1 is fully coated with medical mineral oil 53 before activation, the medical mineral oil 53 forms an oil film on the surface of the drill bit. During drill rotation, the oil film reduces the drill bit temperature, preventing it from overheating. To maintain the temperature of the drill bit and skull surface within a safe range for scalded patients' head tissues, and because the medical mineral oil 53 will not affect the wound, the oil film formed by the medical mineral oil 53 during the drilling process can effectively wrap some of the bone fragments generated during drilling, preventing a large amount of fragments from splashing or adhering to the drill bit and surgical area of ​​the skull drill gun 1 during the drilling process. At the same time, it reduces the mechanical wear and thermal damage of the cutting edge, significantly extending the service life of the drill bit of the skull drill gun 1. After the drilling is completed, the support seat 43 is released, and the spring 45 will drive the components of the pretreatment mechanism 4 to return to their original positions. During the resetting process, the sponge ring 55 will remove the residual bone fragments on the drill bit, preventing bone fragments and bloody secretions from adhering to the drill bit, further reducing the cleaning difficulty of the drill bit 1 of the skull drill gun 1. When the skull drilling work is completely completed, the loading ring 51 can be separated from the rotating ring 48 for cleaning and disinfection.
