Description
Technical Field
The utility model relates to an ankle surgery medical instrument technical field, concretely relates to a director that is used for ankle surgery hollow nail to put into.
Background
When the ankle joint fusion surgery is performed, a doctor needs to place the compression hollow screw into a reasonable position so as to ensure that the compression screw can apply certain pressure to the joint surface and promote the joint fusion. This requires the physician to have a good sense of space and clinical experience. In most cases, it is difficult for the physician to place the cannulated nail in a reasonable position in one go. Therefore, the hollow nail guide needle is required to be repeatedly inserted in the operation, and whether the position of the hollow nail is satisfactory or not is judged through X-ray fluoroscopy. This prolongs the operation time and increases the amount of fluoroscopy and intraoperative bleeding.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a guider for ankle surgery hollow nail is put into.
The specific technical scheme is as follows: the utility model provides a director that is used for ankle surgery hollow nail to put into, includes guiding arm 1 and guide sleeve 2, 1 one end of guiding arm is equipped with a plurality of ke shi needle passageways 3, and the other end is equipped with guide sleeve and puts into bayonet socket 4, and guide sleeve puts into bayonet socket 4 and guide sleeve 2's outline phase-match, and is fixed through the buckle, be equipped with a plurality of diameters size and position and 3 assorted tunnel holes 5 of ke shi needle passageway in the guide sleeve 2, can put into hollow nail guide pin 6 in the tunnel holes 5, the tunnel holes 5 that the diameter equals and ke shi needle passageway 3 are located same axis.
Preferably, the guide arm 1 is in a shape of a C.
Preferably, the number of the kirschner wire channels 3 and the number of the tunnel holes 5 are 3, and the diameters of the kirschner wire channels and the tunnel holes are different.
Preferably, the kirschner wire channels 3 and the tunnel holes 5 are different in size.
Preferably, the hollow nail guide pin 6 has an outer diameter of 4.3mm, 6.5mm and 7.3mm, respectively.
Preferably, the inner diameter of the tunnel hole 5 is equal to the outer diameter of the hollow pin guide pin 6.
The working principle is as follows: can arrange the director in the art in the structure both sides that need put into hollow nail guide pin, to 3 built-in kirschner wires of kirschner wire passageway, remove the exit point of structure, the other end then lies in and puts into hollow nail guide pin in the tunnel hole 5 that the kirschner wire corresponds, after removing the entry point of structure with hollow nail guide pin, can adjust hollow nail guide pin or kirschner wire to the entry point and the exit point of needs as required, can attack the structure with hollow nail guide pin after satisfied with.
The beneficial effects are that: (1) the guider of this application designs according to ankle portion anatomy characteristics, and when calcaneum, talus and shin bone distal end were using hollow nail to fix, need put into suitable position with hollow nail accuracy, and the guider of utilizing this application can avoid putting into hollow nail repeatedly and form artificial osteoporosis, is unfavorable for hollow screw's stable fixed.
(2) The guider is suitable for implanting hollow nails with different sizes in the operation around the ankle joint, and hollow screw guide pins with diameters of 4.3mm, 6.5mm and 7.3mm can be implanted.
(3) The guider of this application is applicable to the operation of putting into of hollow screw around the ankle joint, can obviously reduce operation position blood transport damage, reduces the probability that the operation infection of cutting takes place, and the X ray perspective volume has protected patient and art person in the reducible art simultaneously.
(4) The guider is point-positioned, and peripheral vascular nerves of the ankle joint can be avoided as much as possible, so that iatrogenic injuries are reduced.
