Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a skull processor. Background Art

[0002] The contents of this section merely provide background information related to the present invention and may not constitute prior art.

[0003] Neurosurgery craniotomy or trepanation surgery requires drilling of the skull. Currently, the main methods of skull drilling used in clinical practice include hand-cranked drills, power system self-stop drills, etc. Before reaching the dura mater, a "paper" or "thin eggshell"-like inner skull plate is often retained to prevent damage to important structures such as the dura mater and brain tissue.

[0004] Currently, in clinical practice, when it is necessary to peel off the inner skull plate, a nerve peeler or a micro peeler is usually used to separate the remaining inner skull plate from the dura mater, and then the inner skull plate is removed by mosquito forceps. However, the nerve peeler or the micro peeler was originally a tool used to separate exposed nerves, and therefore, its head end is spherical or flat arc-shaped. When it is used to peel off the inner skull plate remaining after drilling, it is very easy to cause bone window separation between the dura mater and the edge of the drilling hole, thereby increasing the time for intraoperative hemostasis, increasing the operation time and anesthesia time, and increasing the risk of postoperative epidural hematoma.

One end of the first mounting rod 11 away from the abutment plate 12 is fixedly connected to the connecting rod 21, and one end of the second mounting rod 15 away from the separator 16 is fixedly connected to another connecting rod 21.

[0033] A limiter 3 is provided on the handheld portion 1, and the limiter 3 is used to limit the position of the connecting rod 21 on the handheld portion 1. As an embodiment of the present utility model, the connection structure between the first mounting rod 11 and the second mounting rod 15 and the handheld portion 1 is completely consistent.

[0034] Reference Figure 2 , 3 A positioning block 22 is fixedly arranged at one end of the connecting rod 21 away from the mounting hole 2. The bottom of the positioning block 22 is used to abut against the end of the handheld part 1. A mounting ring 31 is rotatably sleeved on the handheld part 1. The mounting ring 31 can only rotate along the outer periphery of the handheld part 1, but cannot slide along the axial direction of the handheld part 1. The stopper 3 is slidably arranged on the mounting ring 31 along the axial direction of the handheld part 1, such as Figure 4 As shown, two limiters 3 are symmetrically arranged along the axis on the outer periphery of the mounting ring 31, and each limiter 3 is in an "L"-shaped structure, including a horizontal piece and a vertical piece.

[0036] As an implementation mode of the present utility model, refer to Figure 3The slide groove 4 is provided as a T-shaped groove, and the slider 41 is provided as a T-shaped block adapted to the slide groove 4; as another embodiment of the utility model, the slide groove 4 can also be provided as a dovetail groove, and the slider 41 is provided as a dovetail block adapted to the slide groove 4.

[0037] Reference Figure 2 , 4 , a slide 5 is arranged beside the positioning block 22, one side of the slide 5 abuts against the positioning block 22, and the other side of the slide 5 is arranged as an inclined surface. That is, the side of the slide 5 away from the positioning block 22 is arranged obliquely, and is in a slope shape from top to bottom. Correspondingly, the side of the horizontal piece of the limiting member 3 opposite to the slide 5 is also arranged as an inclined surface, and the inclination angle of the inclined surface is adapted to the inclined surface of the slide 5. In actual use, since the side of the slide 5 away from the positioning block 22 is arranged obliquely, the staff rotates the mounting ring 31, so that the mounting ring 31 drives the limiting member 3 to rotate. Since the inclined surface of the horizontal piece of the limiting member 3 close to the slide 5 is adapted to the inclined surface of the slide 5, the limiting member 3 can move upward in the slide groove 4 under the support of the slide 5, so that the horizontal piece of the limiting member 3 slides to the top of the positioning block 22, thereby limiting the position of the positioning block 22 to prevent the connecting rod 21 from escaping from the handheld part 1 or axial movement in the handheld part 1.

[0038] Reference Figures 2 to 4 A receiving hole 33 is provided at the top of the positioning block 22 in the vertical direction, a positioning pin 34 is slidably provided in the receiving hole 33, a second elastic member 35 is provided in the receiving hole 33, and the second elastic member 35 is used to drive the positioning pin 34 to move in a direction away from the receiving hole 33. A positioning hole 36 for inserting the positioning pin 34 is provided at the bottom of the cross piece of the limiting member 3, and a driving member 37 is also provided on the cross piece of the limiting member 3.
