Abstract
This utility model discloses a kind of vertebral body card punch of improvement, belong to orthopedic medical device apparatus field, comprise punching cover, punching bar, punching cover is hollow pipe, guiding slope is provided with bottom it, punching cover jacket wall in the relative side on this guiding slope is provided with opening, and the minimum point of this opening is not higher than the minimum point on guiding slope, and punching bar comprises the pushing ram be connected successively, soft elater, the drill bit with certain degree of hardness and toughness.This device utilizes the punching bar with soft elater under the guide effect on guiding slope, stretches out from open loop, realizes side punching, once punches and just can get the hole of enough volumes in vertebral body, clean out enough bone cement headspaces.
Description
Technical field
This utility model relates to a kind of orthopedic medical device equipment, particularly relates to a kind of vertebral body card punch of improvement.
Background technology
At present, bone cement injection operation is mainly used in treating osteoporosis, and compression fracture of vertabral body is the modal complication of sufferers of osteoporosis face, and percutaneous vertebroplasty PVP and Percutaneous kyplasty PKP is a novel minimally invasive surgery formality of spinal surgery.Carry out before bone cement injects, first will punch to vertebral body and in vertebral body, clean out the headspace of injection bone cement.Now, the clinical card punch generally using traditional straight drilling rod formula, can only beat straight hole, but bone cement injects from a straight hole, and injection rate is limited, after bone cement solidifies, only has the fixation of straight line, be difficult to play the fixing of expection and support effect, common solution is, carries out secondary puncture from two sides about vertebral body and punches, bone cement is injected respectively again from two holes, but this mode can increase the difficulty of operation, be increased in epicentral wound, bring more misery to patient.
Summary of the invention
The purpose of this utility model is to provide a kind of vertebral body card punch utilizing flexible punching bar to realize the improvement of side bent downhole, only once need punch and just can get the curved hole of enough volumes in vertebral body, clean out enough bone cement headspaces.
The utility model proposes a kind of vertebral body card punch of improvement, comprise punching cover, punching bar, punching cover is hollow pipe, guiding slope is provided with bottom it, punching cover jacket wall in the relative side on this guiding slope is provided with opening, the minimum point of this opening is not higher than the minimum point on guiding slope, and punching bar comprises the pushing ram be connected successively, soft elater, the drill bit with certain degree of hardness and toughness.
Be provided with a through hole in the middle part of described guiding slope, this through hole overlaps coaxial line with punching.
Described drill bit is screw thread drill bit.
Described punching cover bottom is also provided with cambered surface shell, and described through hole extends to and runs through this cambered surface shell.
Described punching cover is cylindrical drum, and described punching bar is cylindrical bar.
The operating side of punching cover is provided with position fixing handle, the operating side of punching bar is respectively equipped with propelling handle.
The beneficial effects of the utility model are: establish guiding slope in punching cover bottom, there is the punching bar of soft elater under the guide effect on guiding slope, stretch out from open loop, realize side punching, once punch and just can get the hole of enough volumes in vertebral body, clean out enough bone cement headspaces; Punching cover bottom is also provided with cambered surface shell, and fairshaped shell can make punching cover be easier to advance and withdraw from; Guiding is provided with a through hole in the middle part of slope, is to allow the positioning filament imbedding vertebral body in advance pass, with positional punch cover; Only need carry out the improvement of part on traditional vertebral body card punch, increase less cost, but make operation performance significantly promote, and volume and traditional product are small and exquisite equally, operate substantially the same with traditional product, doctor is easy to accept; Punching cover is cylindrical drum, described punching bar is cylindrical bar, be convenient to change operating angle, namely after having punched in side, a position, by pushing ram rollback, then can operate the position fixing handle of punching cover, being rotated to an angle by punching cover again to be rotated by pushing ram advances, multi-angle punching can be realized, expand punching space on demand.In a word, use this device, only need open a hole on vertebral body, need not two side perforatings, greatly alleviate the misery of patient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Reference numeral: punching cover 1, punching bar 2, guiding slope 3, opening 4, pushing ram 5, soft elater 6, drill bit 7, through hole 8, cambered surface shell 9, position fixing handle 10, propelling handle 11.
Detailed description of the invention
With reference to Fig. 1, an embodiment of the present utility model is proposed, the present embodiment comprises punching cover 1, punching bar 2, punching cover 1 is hollow pipe, guiding slope 3 is provided with bottom it, punching cover jacket wall in the relative side on this guiding slope 3 is provided with opening 4, and the minimum point of this opening 4 is not higher than the minimum point on guiding slope 3, and punching bar comprises the pushing ram 5, the soft elater 6 with certain degree of hardness and toughness, the drill bit 7 that are connected successively.Be provided with a through hole 8 in the middle part of described guiding slope, this through hole 8 and punching cover 1 coaxial line, described drill bit 7 is threaded drill bit.Soft elater 6 is overall linear state when not being subject to External Force Acting.Described punching cover bottom is also provided with cambered surface shell 9, and described through hole 8 extends to and runs through this cambered surface shell.Described punching cover 1 is cylindrical drum, and described pushing ram 5 is cylindrical bar.The operating side of punching cover 1 is provided with position fixing handle 10, the operating side of punching bar 2 is respectively equipped with and advances handle 11.
