Abstract
The utility model discloses a vertebra bow root hole drilling apparatus and is characterized in that the apparatus is provided with a handle 1 being able to be held and a drilling rod 2 vertical to the handle. The front end of the drilling rod is a drilling head 3 with a cone-shaped tip 4. The vertebra bow root hole drilling apparatus has the advantages of the length of the drilling head 3 being designed according to the statistical data of an adult joint of lumbar vertebra projecting to the front edge of a vertebra body, the connecting position of the drilling rod and the drilling head being provided with a step to effectively stop the further drilling action of the drilling head to avoid drilling through the vertebra body to damage the important viscera of the front part of the vertebra body, an operator easily using and the hole drilling action being accurate.
Description
This utility model belongs to medical apparatus and instruments, particularly the auxiliary device of the pedicle nail internal fixation operation of the operation of the internal fixation of spine in the bone surgery.
When carrying out the internal fixation of spine operation, need squeeze into pedicle nail in pedicle of vertebral arch, this moment must be earlier in the boring of the relevant position of pedicle of vertebral arch, the present drilling equipment that uses, owing to be not provided with specially, handle is difficult for holding, and the degree of depth of boring does not have rational measure control yet, fully by virtue of experience boring, if misoperation, it is dark to hole, and damages the important organ in vertebral body the place ahead easily, cause bigger operation danger, this should be avoided taking place.Therefore need overcome the deficiency that does not have suitable pedicle nail drilling equipment in the internal fixation of spine operation.The purpose of this utility model has been proposed.
The purpose of this utility model is in order to overcome the above-mentioned middle deficiency that exists, to change the present situation that does not have suitable apparatus in the pedicle nail fixing operation, designing a kind of pedicle of vertebral arch drilling equipment.
The purpose of this utility model is achieved in that this kind pedicle of vertebral arch drilling equipment, has a handle that can grip 1, and with the vertical drilling rod 2 of handle, the front end of drilling rod is a drill bit 3 with taper tip 4.There is a step junction of drill bit and drilling rod, the degree of depth of creeping into control.This device has promptly been realized the purpose of this utility model.
The utility model has the advantages that, simple in structure, easy to use, the length of drill bit 3 is to design according to the statistics dimensional data of adult's articular process of lumbar vertebra to anterior margin of vertebral body, drilling rod to the junction of drill bit has a step, stops further creeping into of drill bit effectively, has avoided boring saturating cone, the preceding important organ of damage cone, the operator uses easily, and boring accurately.Design improvement through suitable can be designed to removable drill bit form, to adapt to the patient of more different crowd, increases its practicality.
Following description of drawings, accompanying drawing are instance graphs of the present utility model, and each sequence number in the accompanying drawing is; 1 handle, 2, drilling rod, 3, drill bit, 4, the taper tip.Tip can be that pyramid such as rhizoma sparganic taper also can be conical.
Below in conjunction with the embodiment in the accompanying drawing, structure of the present utility model and use are described.With reference to accompanying drawing, this pedicle of vertebral arch drilling equipment is characterised in that it has a handle that can grip 1, and with the vertical drilling rod 2 of handle, the front end of drilling rod is a drill bit 3 with taper (or pyramid) tip 4.Whole device adopts metal material, makes as material monolithics such as steel, tool steel, steel alloys, or sectional making, assembling connects then.During operation according to requirements of operation, operator's gripping handle, the drill bit 10-15 degree that slopes inwardly on articular process pierces, this position can guarantee that promptly drill bit is along entering cone in the pedicle of vertebral arch, drill bit is all pierced back (step on the drilling rod is run into articular process of lumbar vertebra), remove drilling equipment, finish pedicle of vertebral arch boring.
