Abstract
The utility model discloses a multifunctional nerve root retractor, comprising an L-shaped rod and a retractor for an end part. The L-shaped rod is a hollow rod. The multifunctional nerve root retractor integrates a traditional retractor and an aspirator. The utility model has the advantages of simple structure, convenient operation, time saving, and labor saving, being a vertebral canal surgical appliance with strong practicability in surgery.
Description
This utility model relates to a kind of surgical operating instrument, relates in particular to a kind of multi-functional nerve root retractor that carries out the canalis spinalis operation.
The doctor is when doing the canalis spinalis operation at present, and nerve root retractor and suction pump are indispensable two apparatuses, and traditional nerve hook is that inclined to one side solid metal is made, and only plays tractive nerve root and spinal cord in operation.Traditional suction pump is thick hollow pipes such as two ends, is used with nerve root retractor in operation, is used for attracting otch soiling solution and otch sepage.The canalis spinalis disc removal operation of performing the operation especially, the visual field of operation is little, and nerve root retractor and suction pump must come into view simultaneously, and the both hands cooperating could be finished operation technique smoothly, very inconvenient and influence operation efficient.
The purpose of this utility model provides and a kind of traditional nerve root retractor and two kinds of apparatuses of suction pump united two into one, and is simple in structure, easy to operate, saves time the multi-functional nerve root retractor in labour-saving.
The technical solution of the utility model is: a kind of multi-functional nerve root retractor comprises
A shape bar and an end drag hook,
The shape bar is a hollow bar.Described
The hole of shape hollow bar band drag hook one end is flaring hole or isometrical hole.
This utility model has following advantage:
1, the function with two kinds of apparatuses merges on the apparatus, makes the both hands compounding practice become one-handed performance, can vacate a hands and go to finish other operation.
2, reduce the intervention of an apparatus, less otch can be exposed in the visual field of operator better, be convenient to enlarge patient's the visual field.
3,
The hole of shape hollow bar band drag hook one end is the flaring hole, and aperture, little rear end, front end aperture is big, is difficult for resulting in blockage when attracting the blood of incision.
Below in conjunction with drawings and Examples this utility model is described in further detail:
Fig. 1 is this utility model structural representation.
The multi-functional nerve root retractor structure of this utility model as shown in Figure 1,
Shape hollow bar 2 is positioned at
The drag hook 1 of shape hollow bar 2 one ends, this drag hook plays tractive nerve root and spinal cord effect when operation, wherein
The hole 3 of shape hollow bar band drag hook one end is flaring hole or isometrical hole, and the hole 4 of the other end is isometrical hole, and the termination in hole 4 connects negative pressure source, under the effect of negative pressure source, and the soiling solution of incision and sepage warp in the operation
Hole 3,4 in the shape hollow bar excretes.
Claims (2)
1, a kind of multi-functional nerve root retractor comprises
