Description

Connector

Technical field

The utility model relates to the field of medical instrument technology, especially a kind of connector.

Background technique

Current market sales of attachment device is mostly the nail-stick system of domino connector and pitman cooperation, the device packet Domino joint body is included, domino joint body is substantially equipped with the cuboid of bending, there are two domino joint body is set Pitman through-hole, one is the totally-enclosed through-hole of outer rim, another is the semi-open through-hole of outer rim, two through-hole side-by-side parallels；Two Through-hole side wall is separately installed with the threaded mounting hole with the through-hole connection, is equipped with compression screw in mounting hole；Outer rim is totally-enclosed Through-hole for accommodate will extended pitman, and the semi-open through-hole of outer rim is for accommodating original pitman, to be mounted on human body For the orientation of backbone, the opening of the semi-open through-hole of outer rim is towards in front of side.

This kind of product is carrying out needing pitman penetrating product side when internal fixation of spine technology connects two pitmans Hole lock pitman again, since the fit tolerance of hole and stick is smaller, therefore it is required that doctor has abundant face in operative connection Bed experience and higher surgical technic.

Utility model content

In order to overcome the shortcomings of that existing connector is easy to cause two pitmans that optimum position, the utility model is not achieved Provide a kind of connector.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of connector, including connector main body, First U-type groove, the first screw thread, the second U-type groove and the second screw thread, the both ends of connector are respectively equipped with the first U-type groove and second U-shaped Slot, perpendicular to connector main body, the second U-type groove is oblique U-type groove and is obliquely installed in the connector main body other end the first U-type groove, Pitman slides into U-type groove and is fixed by lock screw, former and later two can be in different sagittal planes by such U-type groove Pitman connect, enable two pitmans to reach ideal position and realize preferably connection and fixed.

It is internal screw thread, the second screw thread that another embodiment according to the present utility model, which further comprises first screw thread, It for standard thread, is simple to manufacture, easy to use, connection is reliable, and the first screw thread has good effect in terms of sealing with anti-corrosion.

It is in different sagittal planes the utility model has the beneficial effects that the connector can be connected from front end pitman Another pitman plays connection function, and the centre distance of fixed two sides pitman position is variable, can preferably connect two Pitman is finely adjusted simultaneously, makes connector position in optimum position, to reduce operating difficulty and operation risk, reaches fracture The good result of reset and interior fixation.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the schematic cross-section of the utility model.

1. connector main body in figure, 2. first U-type grooves, 3. first screw threads, 4. second U-type grooves, 5. second screw threads.

Specific embodiment

If Fig. 1 is the structural schematic diagram of the utility model, a kind of connector, including connector main body 1, the first U-type groove 2, First screw thread 3, the second U-type groove 4 and the second screw thread 5, one end of connector are equipped with the second U-type groove 4 of opening, which is oblique U Type groove, pitman are slid into oblique U-type groove by opening, then are locked by lock screw, and the other end is equipped with perpendicular to connector master First U-type groove 2 of body can connect another pitman being in different sagittal planes from front end pitman, play connection and make With.

If Fig. 2 is the schematic cross-section of the utility model, two pitmans for sliding into U-type groove are all solid by lock screw Fixed, the first screw thread 3 is internal screw thread, and the second screw thread 5 is standard thread, and being simple to manufacture for threaded connection, easy to use, connection can It leans on, meanwhile, internal screw thread plays the role of anti-corrosion and sealing.

During operation, connector need to be placed on bone face, pitman be put into vertically with connector main body It in one U-type groove 2, is locked in advance using lock screw, other end pitman is slid by the second U-type groove 4, at this time using two kinds U-type groove and the connection type of pitman are finely adjusted the position of connector, so that connector reaches best surgery location, most Two sides screw is locked afterwards, completes fixation and connection to two pitmans.

Claims

1. a kind of connector, including connector main body (1), it is characterised in that: the connector main body (1) is divided into the first U-type groove (2), one end of the first screw thread (3), the second U-type groove (4) and the second screw thread (5), connector main body (1) is equipped with perpendicular to connector The first U-type groove (2) of main body (1), the first U-type groove (2) top are equipped with the first screw thread (3), and connector main body (1) other end is equipped with Second U-type groove (4), the second U-type groove (4) is oblique U-type groove and top is equipped with the second screw thread (5).

2. connector according to claim 1, it is characterised in that: the first screw thread (3) is internal screw thread, and the second screw thread (5) is Standard thread.
