Abstract
The utility model discloses a skull cutting trepan not leaving behind bony defect, which comprises a handle and an aiguille which is a cylinder with the lower fringe provided with a ring of saw teeth, wherein the center of the upper part of the aiguille is provided with a link used to integrate the aiguille and the handle together. The skull cutting trepan not leaving behind bony defect is characterized in not only simple skull cutting with short time, but also small trauma with little bleeding without any bone defect after surgery. With the controlling ring and the structure of positioning ring, the utility model can accurately control the drilling depth; meanwhile, the utility model has a simple structure and safe use.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is a kind of drill for craniotomy that cranium is used of opening when carrying out craniotomy.
Background technology
Carrying out craniotomy when opening cranium, on skull, bore the bone hole of 4 diameter 1.5cm earlier, then the skull between 4 bone holes is being taken off with the operation that undergos surgery with drill for craniotomy.This not only complex operation of cranium method of opening, surgical wound surface is big, and operating time is long, and because these 4 bone holes still exist after surgery, also can bring discomfort to patient.
The utility model content
Open the problems referred to above that the cranium mode exists at existing, the purpose of this utility model is to provide a kind of novel trepan that cranium is used of opening of not leaving over bony defect, and adopts this cranium trepan of opening, and not only makes operation process become simple, and operation wound is little, and postoperative is not left over bony defect.
The cranium trepan of opening of not leaving over bony defect that this utility model provides comprises handle and drill bit, it is characterized in that: described drill bit is a cylinder, cylindrical shape drill bit lower limb has a circle sawtooth, and drill bit central upper portion place has and is used for installing and fixing together connecting rod with handle.
Location during for the ease of operation, can there be an endoporus at the place in described connecting rod axle center, also have axial long hole to communicate on the connecting rod with endoporus, a drill bit staple is arranged in the endoporus, there is the awl point drill bit staple bottom, radially screw is arranged at top, and the axial long hole that dog screw passes on the connecting rod is screwed in the radially screw of drill bit staple.
Pierce the degree of depth for the ease of accurately controlling when performing the operation, on the cylinder top of described drill bit external screw thread can be arranged, a tapped control loop and a locating ring are contained on the cylinder.
On above-mentioned control loop and locating ring, dimpled grain can be arranged, in case the on-slip hands.
The internal diameter of described cylinder bottom and external diameter can also be greater than internal diameter that has externally threaded cylindrical portions may and external diameters, and the internal diameter of the female part of described control loop is less than the internal diameter of no female thread portion.
Thisly only on skull, leave a cannelure when not leaving over the driving the cranium trepan and open cranium of bony defect, then circular bone lobe taken off the cranium process of promptly finishing out, open not only that the cranium process is simple, the time short, and wound little, go out insufficiency of blood.The annular bone lobe that postoperative will take off is placed go back to original position and fixing, can not leave bony defect like this on skull.Adopt control loop and locating ring structure, accurately the keyhole degree of depth is used simple, safety.
Description of drawings
Fig. 1 is a structure chart of driving the cranium trepan of not leaving over bony defect of the present utility model;
Fig. 2 is an A-A cutaway view of opening cranium trepan drill bit shown in Figure 1.
The specific embodiment
Below in conjunction with a preferred embodiment and accompanying drawing the structure of driving the cranium trepan and the principle of not leaving over bony defect of the present utility model is described further.
As shown in Figures 1 and 2, the lower limb of not leaving over the drill bit cylindrical portions may 2 of driving the cranium trepan of bony defect has a circle sawtooth, so that mark cannelure on skull.Cylinder 2 lower diameter have external screw thread greater than upper diameter in the diameter small upper, and the control loop 3 that is used to regulate the degree of depth is contained in cylinder 2 outsides by female thread, and control loop 3 upper diameter are less, and a locating ring 4 is screwed in cylinder 2 tops by female thread.For ease of twisting control loop 3 and locating ring 4, dimpled grain is arranged at its outer surface stone roller.Spin Control ring 3, the distance of control loop 3 bottoms and cylinder 2 lower limbs can be adjusted, to regulate the concentration that pierces of trepan.Locating ring 4 is used to limit control loop 3 makes its location, is piercing Shi Buhui with cylinder 2 rotations so that reserve the control loop 3 of the degree of depth.Place, axle center, cylinder 2 top is connecting rod 7, and the drill bit staple 1 that it is pointed cone that connecting rod 7 has 13, one lower ends of an endoporus assigns in the endoporus 13.Have axial long hole 6 to communicate with endoporus 13 on the connecting rod 7, radially screw is arranged on the drill bit staple 1, a trip bolt 5 passes axial long hole 6 and is screwed on the drill bit staple 1, so that adjust drill bit staple 1 insertion depth in connecting rod 7.There is a ring annular groove 8 connecting rod 7 upper ends.Handle 10 lower ends have installing hole to reach fixedly soket head cap screw 9, and there is rotary sleeve 11 at the middle part, and top is holding end 12.
Connecting rod 7 with drill bit during use inserts in the installing hole of handle 10 lower ends, twist fixing soket head cap screw 9 it is held out against in the annular groove 8 of the connecting rod 7 of drill bit, the prong of handle, at its lower end is inserted on the connecting rod 7 symmetric breach relatively rotates to prevent that drill bit and handle from doing.Adjust trip bolt 5 and make drill bit staple 1 moderate length, damaged at the ossiculum of waiting out a 1-2mm of brill on the skull of cranium, it is damaged that drill bit staple 1 is aligned ossiculum, by adjusting control loop 3 and locating ring 4 to mix up the degree of depth that pierces of drill bit, one holds handle grip end 12, one holds rotary sleeve 11 and rotation, the sawtooth of not leaving over drill bit cylinder 2 lower limbs of driving the cranium trepan of bony defect just can get out annular groove on skull, the circular bone lobe in the groove is taken off just finished the operation of opening cranium process.
