and one end of the handle is fixedly connected with the other end of the guide rod far away from the end part of the arc-shaped structure.
Furthermore, the guide holes are arranged in an array.
Furthermore, the handle is vertically fixed with the guide rod.
Further, the handle and the guide rod are fixed into an integral structure.
Further, the diameter of guiding hole is 2 mm, the diameter of guide bar is 10 mm, the diameter of handle is 8 mm.
Preferably, the number of the guide holes is 5, one of the guide holes is located at the axial center of the guide rod, and the other 4 guide holes are respectively arranged around the periphery of the guide hole located at the axial center of the guide rod.
Preferably, the end of the handle far away from the guide rod is provided with an arc chamfer.
Furthermore, the guide rod and the handle are both made of titanium alloy or stainless steel.
Adopt foretell technical scheme, compared with the prior art, the utility model, its beneficial effect who has is: the utility model discloses the form that the ingenious utilization of scheme set up a plurality of guiding holes on the guide bar guides and puts the needle, and the tip that the guide bar is used for inserting the operation position sets to the arc structure and can effectively reduce interference and foreign matter sense when its operation is operated for medical personnel can operate more smoothly conveniently, and in addition, the specification of guide bar only has 10 mm, and small and exquisite body of rod can be favorable to adapting to minimal access surgery, improves operation quality and location direction efficiency and operation use experience.
Drawings
The invention will be further explained with reference to the drawings and the detailed description below:
FIG. 1 is a schematic structural diagram of the device of the present invention;
FIG. 2 is a sectional view of a schematic structure of the device of the present invention;
fig. 3 is a schematic side view of the device according to the present invention.
Detailed Description
As shown in one of fig. 1 to 3, the apparatus of the present invention includes:
the guide rod comprises a guide rod 1, wherein one end part of the guide rod 1 is provided with an arc-shaped structure 11, a plurality of guide holes 12 are formed in the guide rod 1 along the axial direction of the guide rod, the guide holes 12 penetrate through two ends of the guide rod 1, at least one guide hole is axially parallel to the guide rod 1, an included angle is formed between at least one guide hole and the guide rod 1 along the axial direction, the two ends of the guide hole are respectively positioned at the tail ends of the two ends of the guide rod 1, and in addition, the guide hole forming an included angle with the guide rod 1 along the axial direction is obliquely drilled near the center of the end part of the;
one end of the handle 2 is fixedly connected with the other end of the guide rod 1 far away from the end part of the arc-shaped structure 11.
In order to facilitate the needle positioning operation in different directions, the guide holes 12 are arranged in an array, and as a possible implementation manner, the number of the guide holes 12 is 5, one of the guide holes is located at the axial center of the guide rod 1, and the other 4 guide holes are respectively arranged around the periphery of the guide hole located at the axial center of the guide rod 1.
