Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to an orthopedic surgery is with ware of opening a way.
Background
When patients with herniated and prolapsed intervertebral discs, spinal orthopedic reconstruction and the like are subjected to surgical treatment, vertebral bodies need to be stabilized by means of spinal connecting rods and pedicle screws, the pedicle screws generally consist of screw bodies, tulip-shaped connectors and compression screw plugs, when the screw bodies are implanted into the pedicle portions, the bottoms of the connectors can correspondingly contact with vertebrae, and the physiological shape of the pedicle portions at the posterior position often cannot enable the connectors to be stably seated and fixed. At present, bone matters needing to be removed at the vertebral pedicle are generally removed by rongeur in an orthopedic doctor operation, the operation method is low in working efficiency, blind operation which cannot be accurately positioned is mostly performed, and the effect is not ideal.
The existing surgical instruments used by orthopaedics doctors in the operation often cannot achieve the expected open-circuit effect of the operation, so the doctors need an instrument which not only can accurately position the position of the implanted nail and remove the redundant bone, but also can establish a stable implantation space to help the doctors to quickly, accurately and efficiently complete the operation process.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing an orthopedic operation is with ware of opening a way, this ware of opening a way can unscrew earlier a space that is fit for pedicle screw connector before implanting the pedicle screw, in order to realize above-mentioned purpose, the utility model provides a following technical scheme:
an orthopedic surgical circuit opener, comprising: the integrative body of rod and the rotating head that links to each other, the trailing end connection of the body of rod has the handle, the handle periphery is silica gel material and its tail end tip is the smooth hammer of metal material.
Further, the even spiral of rotating head circumference is provided with a plurality of blades, each all be provided with the cutting edge on the blade length direction, the head end tip of rotating head also is provided with the cutting edge, and is adjacent be the chip groove between the blade.
Furthermore, the center of the head end of the rotating head is a needle head with a pointed end, and the center line of the needle head is collinear with the center line of the rod body.
Further, the rotating head is conical as a whole, and the diameter of the rotating head is gradually reduced from the proximal end to the distal end.
Drawings

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 3, an orthopedic surgery circuit breaker is characterized by comprising: an organic whole body of rod 1 and rotating head 2 that links to each other, the trailing end connection of the body of rod 1 has handle 3, 3 peripheries of handle are silica gel material and its tail end tip is the smooth hammer of metal material.
The doctor can use the apparatus to strike the slide hammer in the operation, realizes deepening gradually of ware of opening a way.
The even spiral of 2 circumference of rotating head is provided with a plurality of blades 4, each all be provided with the cutting edge on the 4 length direction of blade, the head end tip of rotating head 2 also is provided with the cutting edge, and is adjacent be the chip groove between the blade 4.
The center of the head end of the rotating head 2 is a needle head 5 with a pointed end, and the central line of the needle head 5 is collinear with the central line of the rod body 1.
The needle head 5 has the positioning function in the operation, and helps a doctor to perform an open circuit operation after determining the nail inserting position.
The rotary head 2 is conical as a whole, and the diameter of the rotary head is gradually reduced from the near end to the far end, and the head end of the rotary head 2 with smaller diameter can be deeper in the axial direction faster than the straight rotary head in actual operation.
Referring to the attached figure 4, the circuit breaker can be designed into a quick-change handle, a doctor can select the handle to be integrally connected with the rod body or the quick-change handle according to the operation habit and the actual operation condition, and correspondingly, the tail end of the circuit breaker of the quick-change handle is provided with a bayonet which can be clamped with the handle.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
