Description

Orthopedic drilling guide device

Technical Field

The utility model belongs to the technical field of medical equipment, an orthopedics drilling guider is specifically disclosed.

Background

Is composed of bone, bone marrow and periosteum, and contains abundant blood vessels and nervous tissue. The two ends of the long bone are spongy cancellous bone, the middle part of the long bone is dense and hard cancellous bone, the center of the long bone is a medullary cavity, and bone marrow is contained in the medullary cavity and gaps of the cancellous bone. The bone marrow in the marrow cavity of the children is red and has hematopoietic function, and gradually loses the hematopoietic function with the increase of the age, but the red bone marrow with hematopoietic function is maintained for the whole life in the two ends of the long bone and the cancellous bone of the flat bone. The periosteum is a connective tissue membrane covering the surface of a bone, is rich in blood vessels and nerves, plays a role in nourishing bone, and has osteoblasts in the periosteum, so that a bone layer can be proliferated, and damaged bone tissues can be healed and regenerated.

When the bone is diseased or damaged, the bone needs to be repaired through an operation; in the bone surgery, often can be on the bone drilling, the operation operator usually holds drilling tool and trompil during drilling, and the trompil process receives the influence of operator's action easily, and the operator hand only takes place to remove, will be drilling direction change, can cause serious harm for patient like this.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an orthopedics drilling guider to solve the problem that the orthopedics drilling in-process caused serious harm for patient because the operation is unstable.

In order to achieve the above object, the basic scheme of the utility model is: the utility model provides an orthopedics drilling guider, includes the backup pad, and the backup pad lower part is equipped with branch, has seted up the through-hole in the backup pad, and the both sides that the backup pad is located the through-hole are equipped with the montant respectively, are connected with the horizontally diaphragm between two montants, and the diaphragm can two montant length direction straight slips, is equipped with the scale on the montant, is equipped with the motor that the output shaft arranged downwards on the diaphragm, and coaxial coupling has the drill bit that can pass the through-hole.

The working principle of the basic scheme is as follows: when the device is used for drilling, the supporting rod is placed around a position needing drilling, the center of the through hole is opposite to the drilling position, the motor is started, and the output shaft of the motor rotates to drive the drill bit to rotate; the cross rod is pushed to move downwards, and the drill bit drills after contacting the bone.

The beneficial effect of this basic scheme lies in:

(1) in the scheme, the scales are arranged on the vertical rod, and the moving distance of the transverse plate can be judged by observing the scales, so that medical personnel can conveniently judge the drilling depth;

(2) through setting up two montants in this scheme, enable the diaphragm and remove along the length direction of montant, can not make the motor take place to swing like this, improved stability.

Furthermore, a fixed plate is connected between the upper parts of the two vertical rods, an air cylinder with a piston rod arranged downwards is arranged at the lower part of the fixed plate, and the piston rod of the air cylinder is connected with the transverse plate. Through setting up the cylinder, stretch out through the piston rod of control cylinder, can stably promote the diaphragm and remove, improved the stability in the use.

Furthermore, the vertical rod is hinged with the supporting plate, the transverse plate is provided with a sliding hole for the vertical rod to move, and the vertical rod is provided with a positioning part for positioning. Through the swing montant, can adjust the orientation of drill bit, be convenient for drill to different directions.

Furthermore, location portion includes that the slope is seted up in the screw hole of montant lower part, and threaded hole female connection has positioning bolt, and a plurality of locating holes have been seted up to the backup pad. The positioning bolt can extend into the positioning hole. Through setting for the position bolt, can stretch into the positioning bolt in the locating hole, can play better positioning action to the montant like this.

Furthermore, the lower part of the supporting rod is hinged with a stabilizing plate, and the lower end face of the stabilizing plate is corrugated. Through articulated backup pad, can increase the holding surface of branch lower part, improved the stability of this device.

Furthermore, a silica gel layer is adhered to the lower end face of the stabilizing plate. Through setting up silica gel, can play the antiskid effect, after stabilizer plate and skin contact, can also play the guard action to skin.

Drawings

Fig. 1 is a schematic view of a partial cross-sectional structure of an embodiment of the guiding device for orthopedic drilling according to the present invention.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a supporting plate 1, a supporting rod 2, a stabilizing plate 3, a through hole 4, a vertical rod 5, a sliding hole 6, a positioning bolt 7, a positioning hole 8, a transverse plate 9, a motor 10, a drill bit 11, a fixing plate 12 and a cylinder 13.
