Description
Technical field
This utility model relates to medical apparatus and instruments, and especially one has fixed function, angle adjustment is convenient, is convenient to the sustentaculum of talus internal fixtion guider of guide pin being inserted precalculated position.
Background technology
Wicresoft's synthetism internal fixation operation oneself so become fashion trend.International internal fixtion tissue (AO tissue) is applied through the research of many decades in the fractures principle of the proposition in early days of establishments, now own substitute by BO (biological osteosynthesis) theory.The core of BO utilizes rational resetting technique, do not appear fracture end as far as possible, to protect the blood supply of fracture site, and carries out stable internal fixtion to fracture, but not strong internal fixtion.Thus provide good biological environment for union of fracture.Especially the fracture of irregular bone, internal fixtion more requires Wicresoft as much as possible, and because its articular surface is many, flesh and blood damages for when being easily cut open reset, and closed reduction guide cylinder internal fixtion will become the first-selection of irregular bone fractures.As fracture of scaphoid bone of wrist, calcaneus fracture, fracture of calcaneus etc. all require Wicresoft's internal fixtion, to reduce the probability of bone does not connect, osteonecrosis etc.Closed reduction guide cylinder internal fixtion needs precise guidance, to reach desired location when screw is inserted, and stable fixing.At present both at home and abroad guide cylinder internal fixtion mainly relies on artificially, experience inserts guide pin, and the inserting of guide pin often needs repetitiously under C arm machine is had an X-rayed to insert, locate.Easily cause artificial osteoporosis when repeatedly inserting, be unfavorable for the fixing of guide cylinder, thus affect the fastness of internal fixation screw.
Calcaneus medial surface sub-dermal soft tissue is thick, the curved depression of surface of bone.In 1/3 have a flat projection, be sustentaculum tali.Its cortical bone is thick and hard.Sustentaculum tali there is deltoid ligament, the attachments such as plantar calcaneonavicular ligament.Because sustentaculum of talus is positioned at inside calcaneus, appear difficulty in art, anatomical reduction accurately cannot be realized, give in operation fixation procedure and bring certain difficulty.
Chinese patent " 2014100274980 " discloses a kind of posture pressurization multipurpose guider, this guider is made up of body frame and guide cylinder, be fixed on skeleton by body frame, utilize the mode of pressurization that guider is inserted skeleton, again screw is imported guider, rely on guider hold-down screw to insert angle and position, complete internal fixation operation.And due to the difference of human development, everyone skeletal shape, size are also not quite similar, when utilizing body frame to be fixed, be difficult to ensure that the position of guider and angle reach state the most suitable, desirable, still need to rely on artificial experience to judge, there is certain error, and after body frame is fixing, pinpoint the problems and can not finely tune, be unfavorable for that operation process and patient recover.
Summary of the invention
To be solved in the utility model is exactly in sustentaculum of talus fracture operation, internal fixtion inserts screw position and angle is difficult to judge, doctors experience is relied on to perform the operation, existing guider still needs to rely on artificial judgement in fixation procedure, and after body frame is fixing, guider angle can not be finely tuned, easily cause error, be unfavorable for the problem of operation process and patients ' recovery, there is provided a kind of angle adjustment convenient and there is fixed function, being convenient to the sustentaculum of talus internal fixtion guider of guide pin being inserted precalculated position.
Sustentaculum of talus internal fixtion guider of the present utility model, it is characterized in that this guider comprises localizer and guider, guider is arranged on localizer, wherein: localizer is cross fixed mount, fixation hook is provided with in its each termination, cross centre position is provided with circular hole, and circular hole aperture is mated with guider; Guider is hollow circular tube, and its internal diameter equals circular hole aperture, and the connecting portion of guider and holder is provided with three rules, three rules respectively between be spaced apart 120 °, each rule two ends are connected with guider, holder respectively.
Described rule is provided with limiting card, for the rotational angle of limit guides.
First, patient's calcaneus is carried out three dimensional CT unenhanced after stored in computer, utilize three-dimensional software reconstruction of three-dimensional images, the concrete shape of calcaneus, size are reduced, Measurement and analysis is carried out to image simultaneously, in the preoperative guider angle is drafted, afterwards the guider of actual guider is adjusted according to computer simulation angle value out, by limiting card fixed guider angle, just can be used for operation, so pass through area of computer aided, can accurately position, avoid the error that anthropic factor brings, improve surgical effect, alleviate patient's misery.
Sustentaculum of talus internal fixtion guider of the present utility model, design science, structure is simple, easy to use, auxiliary adjustment is carried out by computer, adopt between guider and localizer and be rotationally connected, be aided with rule simultaneously, angle adjustment can be carried out according to the concrete condition of different sufferer more intuitively, avoid the error that anthropic factor brings, improve surgical effect, alleviate patient's misery, after computer digital process, according to the different situations of each patient, personalization and the precision of sustentaculum of talus fracture operation can be realized.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Wherein, localizer 1, fixation hook 2, guider 3, rule 4, limiting card 5.
Detailed description of the invention
Embodiment 1: a kind of sustentaculum of talus internal fixtion guider, comprise localizer 1 and guider 3, guider 3 is arranged on localizer 1, wherein: localizer 1 is cross fixed mount, fixation hook 2 is provided with in its each termination, cross centre position is provided with circular hole, and circular hole aperture is mated with guider 3; Guider 3 is hollow circular tube, and its internal diameter equals circular hole aperture, guider 3 and the connecting portion of holder be provided with three rules, 4, three rules 4 respectively between be spaced apart 120 °, each rule 4 two ends are connected with guider 3, holder respectively.Rule 4 is provided with limiting card 5, for the rotational angle of limit guides 3.
First, patient's calcaneus is carried out three dimensional CT unenhanced after stored in computer, utilize three-dimensional software reconstruction of three-dimensional images, by the concrete shape of calcaneus, size is reduced, Measurement and analysis is carried out to image simultaneously, in the preoperative guider 3 angle is drafted, afterwards the guider 3 of actual guider is adjusted according to computer simulation angle value out, by limiting card 5 fixed guider 3 angle, just hands art can be used for, so pass through area of computer aided, can accurately position, avoid the error that anthropic factor brings, improve surgical effect, alleviate patient's misery.
