Description
Technical field
The utility model relates to medical instruments fields, and in particular to a kind of elastic poker for being bonded skull shape.
Background technique
Currently, clinically because of the needs for the treatment of illness, it is often necessary to which in intracerebral, temporarily or permanently implantation catheter and correlation are filled
It sets, operation needs subcutaneously to beat tunnel from cephalic incision to abdominal incision using poker, and conduit or conducting wire are placed in.It is currently used
It is exactly straight, have the hollow metal poker of tube core from incision of scalp, through scalp galea lower layer, to ear after be pierced by, then along neck,
A hypodermic tunnel is made in chest, abdomen segmentation, and go directly abdominal incision.
When from the crown, point of puncture notch does hypodermic tunnel to postauricular incision, the radian of patient's skull is different and does not advise
Then, straight and hard subcutaneous poker needs patient's rule of thumb pre-bending, since poker has comparable hardness, is difficult to make curved arc
Degree and skull extremely agree with, cause it is unnecessary under scalp be bent not enough by excessive removing or poker, poker is hard to reach ear
Notch afterwards increases the difficulty and risk of operation.
Utility model content
In view of the deficienciess of the prior art, the utility model provides a kind of elastic poker for being bonded skull shape, solution
Poker hardness of having determined is big or bending not enough causes the problem of increasing operating difficulty and risk.
To achieve the goals above, the utility model is realized by the following technical solutions: a kind of fitting skull shape
Elastic poker, including handle, poker main body and head, poker main body is arc and has elasticity, one end of poker main body with
Handle is detachably connected, and the other end is detachably connected with head, is arranged in poker main body and matches with poker main body
Hollow pipe.
The elastic poker of arc in the utility model, in its natural state arc-shaped elastic poker from crown notch into
Enter, along skull under galea or subperiosteum gap is pierced by along skull to postauricular incision, removes poker head and handle, take
Poker out, conduit or conducting wire are sent into from hollow pipe.During elastic poker insertion, the operation such as pre-bending is not needed due to having,
Reduce the workload of doctor, it is disposable to form head hypodermic tunnel, avoid tunnel notch on the way.
Further, the curvature of poker main body is greater than the curvature of skull.Poker main body can be close to skull, make elastic poker
More it is bonded skull.
Further, poker main body is arc elastic steel bar or Nitinol strip.Elastic steel strip and Nitinol strip
Material is cheap, and materials are convenient, same easy to clean and disinfection.
Further, the cross section of poker main body is rectangle or semicircle.Cross section is rectangle or semicircular poker master
Body can keep hardness, and in the case where pushing away holding force and effectively transmitting, elastic poker will not swing.
Further, end face of the head far from poker main body is cambered surface.When being punctured, subcutaneous group can be avoided damage to
It knits.
Further, the outer diameter of hollow pipe and the diameter on head are identical.Keep poker surface round and smooth smooth, it is streamlined, subtract
Resistance when few head punctures.
Further, the both ends of poker main body are connect with handle and head threads respectively.Screw connection structure is simple, convenient
It dismantles, after the completion of subcutaneous puncture tunnel, rotating handle or head facilitate and take out poker main body.
Further, handle includes annulus and connector, and connector is connect with the threaded one end of poker main body, and connector
Diameter be equal to the outer diameter of hollow pipe, annulus connect with connector.Annulus can be convenient the elastic poker of gripping and control direction, even
The convenient installation with elastic poker of connector.
The utility model has the beneficial effects that the elastic poker of the fitting skull shape of the utility model does not need the behaviour such as pre-bending
Make, elastic poker can be made to be bonded the shape of skull completely, it is easy to use, damage small, shortening operating time, more convenient operation.And
A hypodermic tunnel can disposably be formed using hollow pipe, avoid tunnel notch on the way, materials are convenient, low manufacture cost, equally
Easy to clean and disinfection.
