Description
Technical field
This utility model belongs to technical field of medical instruments, especially relates to a kind of drag hook for neurosurgery.
Background technology
Along with the development of neurosurgery, operating theater instruments application in operation process plays an important role, and scalp retractor is for exposing the requisite instrument of surgical field of view in neurosurgery.Traditional scalp retractor has the disadvantage that drag hook needs special messenger and carrys out tractive or be fixed on the handrail of bedside, the former operate cumbersome, waste time and energy, great work difficulty is added to medical worker, if the position of the handrail on the latter patient's distance operation table is inconsistent, sometimes drag hook cannot be directly anchored on handrail, makes troubles to practical operation；The bill of drag hook is more sharp-pointed, extremely easily injure the skin of patient, the coupler body of a drag hook only has a gib head simultaneously, cannot meet and expose bigger surgical field of view in a position or adjoining position, multiple drag hook can only be taked, the place of so fixing drag hook is relatively many, and operator easily encounter drag hook fixed position in operation, bring unnecessary trouble.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, can be fixed drag hook according to practical situation and can meet two gib heads and pull open the drag hook for neurosurgery of adjacent scalp, is especially suitable in neurosurgery.
The technical solution of the utility model is: a kind of drag hook for neurosurgery, including coupler body, gib head, the side of connector is opening, and this opening part is provided with connection axle, the described two ends connecting axle are located at the corresponding roof of connector respectively through bearing, on diapire, the outer wall connecting axle is circumferentially provided with screw thread, connecting, axle is arranged with two coupler bodies, the both sides of each described coupler body are fixed on connection axle respectively through nut, the described coupler body other end is provided with gib head, described gib head is arc-shaped, the bill of gib head is spheroidal, another sidewall of connector is provided with torque arm bar, screwed hole, torque arm bar is respectively arranged on two opposite sides of connector with being connected axle, the described torque arm bar other end is set in torque arm set, it is provided with through hole on torque arm is overlapped, bolt traverse through hole and then fixing torque arm bar, bottom wall outer at torque arm set is provided with drawstring, the drawstring other end is connected with the flexible collar, screw one end is fixed in screwed hole, the other end is connected with junction button by stretch cord.
Further, the profile of described connector is cuboid.
Further, described coupler body includes cross bar, brace, and described cross bar one end is connected with gib head, and the other end is connected with brace.
Further, in 2 coupler bodies, in 120 ° between cross bar and the brace of one of them coupler body, in 60 ° between cross bar and the brace of opposite side coupler body.
Further, the top of screwed hole is located at by described torque arm bar.
Further, the described flexible collar is the elastic cord collar.
This utility model has the advantage that and has the benefit effect that owing to adopting technique scheme, according to operation periphery actual environment, can select the mode of fixing drag hook, convenient；Two gib heads arranged, meet and can place different gib heads on a drag hook, can regulate the distance between two gib heads according to practical situation, decrease the fixed position of drag hook, to the operating environment that operation is provided convenience.

Detailed description of the invention
Such as Fig. 1, shown in 2, the technical solution of the utility model is: a kind of drag hook for neurosurgery, including coupler body 1, gib head 2, the side of connector 3 is opening, and this opening part is provided with connection axle 4, the described two ends connecting axle 4 are located at the corresponding roof of connector 3 respectively through bearing, on diapire, the outer wall connecting axle 4 is circumferentially provided with screw thread, connecting, axle 4 is arranged with two coupler bodies 1, two gib heads 2 arranged, meet and a drag hook can be placed different gib heads 2, the distance between two gib heads 2 can be regulated according to practical situation, decrease the fixed position of drag hook, to the operating environment that operation is provided convenience, the both sides of each described coupler body 1 are fixed on connection axle 4 respectively through nut 5, described coupler body 1 other end is provided with gib head 2, described gib head 2 is in arc-shaped, the bill of gib head 2 is spheroidal, prevent from scalp is caused secondary injury；
Another sidewall of connector 3 is provided with torque arm bar 6, screwed hole, torque arm bar 6 is respectively arranged on two opposite sides of connector 3 with being connected axle 4, described torque arm bar 6 other end is set in torque arm set 7, overlap in torque arm and be provided with through hole on 7, bolt 8 is through through hole and then fixing torque arm bar 6, and the bottom wall outer overlapping 7 in torque arm is provided with drawstring 9, and drawstring 9 other end is connected with the flexible collar 10, screw 11 one end is fixed in screwed hole, and the other end is connected with junction button 13 by stretch cord 12.
In the present embodiment, the profile of described connector 3 is cuboid.
In the present embodiment, described coupler body includes cross bar 14, brace 15, and described cross bar 14 one end is connected with gib head 2, and the other end is connected with brace 15.
