Description
Technical Field
The utility model belongs to the technical field of medical equipment, concretely relates to steel sheet setting element for anterior cervical spine operation.
Background
At present, steel plates are needed for fixation in anterior cervical surgery. However, the exposure range is limited during the operation process, so that the accurate position of the steel plate cannot be determined under direct vision, and the accurate position needs to be determined through X-ray machine fluoroscopy. The current temporary fixing needle is positioned in the center of a steel plate, has obvious extrusion to the esophagus on the front side of the cervical vertebra in the perspective process and is easy to cause injury, and once the front edge of the vertebral body has hyperosteogeny, the fixing needle can be not fixed tightly and moves. If the steel plate is not suitable for replacement, the fixing pin needs to be pulled out, the former fixing position cannot be found after the steel plate is replaced, X-ray machine perspective needs to be repeated for many times, and the fixing position is possibly inaccurate.
SUMMERY OF THE UTILITY MODEL
The utility model mainly aims at providing a steel sheet setting element for anterior cervical vertebra operation convenient to operation is gone on.
In order to achieve the main purpose, the steel plate positioning piece for anterior cervical spine surgery provided by the utility model comprises a first part and a second part which are connected with each other, wherein the first part is a cylinder, the second part is a cone, and the first part and the second part are coaxially arranged; the first portion has a diameter of 1.5 to 2mm, the second portion has a bottom surface diameter of 0.6 to 1mm, and the second portion has a length of 2 to 4 mm.
According to the scheme, the steel plate positioning piece is nailed into a screw hole on one side of the steel plate at an inclined angle along the exposed gap between the organ sheath in front of the cervical vertebra and the vascular sheath, the first part is used for positioning the steel plate, the second part is used for nailing, the diameter of the bottom surface of the second part is 0.6-1 mm, the length of the second part is 2-4 mm, the nailing depth of the steel plate positioning piece can be limited, the steel plate positioning piece is prevented from causing any oppression and damage to the esophagus, the diameter of the first part is 1.5-2 mm, so that the steel plate with the nail hole diameter of 4mm has a fine adjustment moving space of at least 1mm, when the steel plate is required to be replaced, the steel plate can be directly taken out along the steel plate positioning piece and replaced by the steel plate with a proper length, the operation can be completed by ensuring that 2X-ray fluoroscopy at most, even the position of the micropore nailed into the vertebral body is changed, the strength of a screw channel, greatly facilitates the operation and minimizes the damage to the patient.
Preferably, the length of the first portion is from 6 to 10 cm.
Further, the length of the first portion is 6 to 7 cm.
Further, the length of the first portion is 10 cm.
Further, the length of the second portion is 3 mm.
Furthermore, the steel plate positioning piece is an integrally formed piece.
Drawings
The invention is further described with the aid of the accompanying drawings, in which, however, the embodiments do not constitute any limitation to the invention, and for those skilled in the art, other drawings may be obtained without inventive effort from the following drawings.
Fig. 1 is a structural diagram of an embodiment of a steel plate positioning member according to the present invention.
Fig. 2 is a schematic view of an embodiment of a steel plate positioning member according to the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1 and 2, the steel plate positioning member 100 for anterior cervical spine surgery provided in this embodiment includes a first portion 1 and a second portion 2 connected to each other, the first portion 1 is a cylinder, the second portion 2 is a cone, and the first portion 1 and the second portion 2 are coaxially disposed; the diameter of the first portion 1 is 1.5 to 2mm, the diameter of the bottom surface of the second portion 2 is 0.6 to 1mm, and the length of the second portion 2 is 2 to 4 mm. The length of the second portion 2, is the length of the second portion 2 along its axis of revolution
Preferably, the length of the first portion 1 is 6 to 10 cm; further, the length of the first portion 1 is 6 to 7 cm; further, the length of the first portion 1 is selected to be 10 cm. The length of the first portion 1 refers to the length of the first portion 1 along its axis of rotation. The rotation axis of the first portion 1 coincides with the rotation axis of the second portion 2, and both the rotation axis of the first portion 1 and the rotation axis of the second portion 2 are the rotation axes of the steel plate positioning member 100.
Preferably, the length of the second portion 2 is 3 mm.
The steel plate positioning member 100 is an integrally formed member.
Referring to fig. 1 and 2, a medical worker inserts a steel plate positioning member 100 into one side of a steel plate 5 at an inclined angle along an exposed gap between a cervical vertebra anterior organ sheath and a vascular sheath, the steel plate 5 passes through a screw hole 6, the steel plate 5 is provided with two screw holes 6, each screw hole 6 is inserted with a steel plate positioning member 100, a first portion 1 is used for positioning the steel plate 5, a second portion 2 is used for inserting a vertebral body, the diameter of the bottom surface of the second portion 2 is 0.6 to 1mm, the length of the second portion 2 is 2 to 4mm, the insertion depth of the steel plate positioning member 100 can be limited, any compression and damage of the steel plate positioning member 100 to the esophagus are avoided, the diameter of the first portion 1 is 1.5 to 2mm, so that the steel plate 5 with the diameter of the screw hole 6 of 4mm has a fine adjustment moving space of at least 1mm, when the steel plate needs to be replaced, the steel plate can be directly taken out along the rotation axis of the steel plate positioning member 100 and replaced with a proper length without taking out the steel plate 100, further ensuring that the operation can be completed by 2X-ray fluoroscopy at most, the fixing failure caused by the strength of the screw channel sclerotin can not be influenced even if the position of the micropore formed by the nail into the vertebral body is changed, greatly facilitating the operation and reducing the damage to the patient to the minimum.
Finally, it should be emphasized that the present invention is not limited to the above-described embodiments, but only to the preferred embodiments of the invention, and the invention is not limited to the above-described embodiments, and any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present invention should be included in the scope of the present invention.
