CN201157382Y - Guiding device for drilling hole of orthopaedics - Google Patents

Abstract

The utility model discloses a drill-oriented device used in orthopedics, which comprises a coaptation screw and a screw tap matched with the coaptation screw. The outer surface of the screw tap is sleeved with a fixing sleeve matching with the diameter of the screw tap. When a screw tapping is done to the bone joint, the positioning can be conducted by arranging the fixing sleeve on the periphery of the screw tap, so that injuries fail to be caused to the surrounding tissues and joints of the coaptation site, the operation is comparatively convenient, the positioning is accurate, the duration of surgery can be shortened and the suffering of a patient can be alleviated.

Description

The orthopaedics drilling guide device

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of orthopaedics drilling guide device.

Background technology

At present in the orthopaedics of hospital, the internal fixation of fracture site adopts screw or draw point to fix more, often use positioner to hole at surface of bone in the operation with the control drill bit, the back with screw tap in the duct internal tapping, be convenient to the screw-in of screw and fixing, and in existing tapping process in default of locating guide device, mostly adopt the range estimation aiming, direction and length all are difficult to grasp, the accuracy of influence positioning and guiding the time to the bone drilling and tapping, cause screw tap that the bone hole is produced deviation easily, so the skew of the bone hole site of screw tap far-end axis and required tapping in the operation practical operation, usually occurs, cause drilling and tapping and location to be wasted time and energy, prolonged operating time, cause bone screw and blade plate can't accurately located fixedly the time, cause easily and repeatedly repeat to squeeze into, can cause the sclerotin splitting when serious, and can cause the damage of infantile myasthenia tissue on every side at the sharp keen screw thread of tapping process plug tap with tapping, cause and when tapping, need many people's operations, waste of manpower.

The utility model content

Technical problem to be solved in the utility model provides a kind of simple in structure, easy to use, and positioning and guiding is accurate, prevents the orthopaedics drilling guide device of synthetism position tissue and joint injury.

For solving the problems of the technologies described above, the technical solution of the utility model is: the orthopaedics drilling guide device, comprise the screw tap suitable with bone screw, and the outer surface of described screw tap is arranged with the fixed cover suitable with its diameter.

As a kind of improvement, the bottom of described fixed cover is provided with fixed teeth.

Owing to adopted technique scheme, the orthopaedics drilling guide device, comprise the screw tap suitable with bone screw, the outer surface of described screw tap is arranged with the fixed cover suitable with its diameter, by periphery fixed cover is set at described screw tap, make when osteoarthrosis is carried out tapping, can locate, make the accurate tapping of screw tap by fixed cover, be unlikely to cause the damage of synthetism position surrounding soft tissue, and to steel plate and bone screw location the time, can utilize the fixed cover location, make screw not depart from the screw of being attacked, use more convenient, and accurate positioning, can shorten operating time, alleviate patient's misery.

Description of drawings

Accompanying drawing is the structural representation of this utility model embodiment.

The specific embodiment

As shown in the figure, the orthopaedics drilling guide device comprises the screw tap 1 suitable with bone screw, and the outer surface of described screw tap 1 is arranged with the fixed cover 2 suitable with its diameter, and the bottom of described fixed cover 2 is provided with fixed teeth 3.

In use; by screw tap 1 to the bone surface drilling and tapping; with the screw-in that makes things convenient for screw and fixing; be placed on fixed cover 2 on the surface of bone that needs boring by blade plate so earlier; screw tap 1 can move up and down in fixed cover 2; rotate screw tap 1 with required synthetism position tapping by handle 4; can on fixed cover 2, mark scale as required; observe the degree of depth that screw tap 1 enters surface of bone with convenient,, can not twist in the screw tap process into infantile myasthenia tissue on every side because the protection of fixed cover 2 is arranged; thereby alleviated wound; reduced manpower, improved therapeutic efficiency, the bottom of fixed cover 2 is provided with fixed teeth 3; prevent that like this fixed cover 2 moves on surface of bone because of the screw tap 1 that firmly causes in tapping process; play the effect of guide-localization, use more conveniently, and can when screwing in screw, play the effect of guiding; can not produce and depart from; accurately convenient, reduced operating time, alleviated patient's misery.

Claims (2)

1. the orthopaedics drilling guide device comprises the screw tap suitable with bone screw (1), it is characterized in that: the outer surface of described screw tap (1) is arranged with the fixed cover suitable with its diameter (2).

2. orthopaedics drilling guide device as claimed in claim 1 is characterized in that: the bottom of described fixed cover (2) is provided with fixed teeth (3).
