Multi-directional retraction device for spinal surgery

Abstract

The invention provides a multi-directional retraction device for spinal surgery. The device comprises a fixing ring and a plurality of retraction assemblies; each retraction assembly comprises a retraction plate, a vertebral body stabilizing needle and a connector, each retraction plate is in a long strip shaped and is provided with a limiting hole running through the retraction plate in the length direction, each vertebral body stabilizing needle comprises a threaded head at the front end and a clamping block at the rear end and penetrates through the corresponding limiting hole, the clampingblocks are clamped to the retraction plates, and the threaded heads penetrate out from the limiting holes; the connectors are in matched connection with the fixing rings, and each retraction plate isconnected with the corresponding connector through a pull rod. When the multi-directional retraction device is in use, the device does not need to be fixedly connected with an operating table bed frame, the positions and postures of the retraction plates can be finely adjusted during use, and great convenience is brought to the surgical operation.

Description

technical field [0001] The invention relates to medical instruments, in particular to a multidirectional retractor for spinal surgery. Background technique [0002] In surgical operations, it is usually necessary to use retractors or retractors to complete the surgical exposure step. The basic process of so-called surgical exposure is as follows: incision of the surface skin of the human body, and use of retractors or retractors at the incision to pull the human tissue under the incision, so that the lesion in the body is in an ideal exposure state. [0003] There are some disadvantages in the use of traditional multi-directional retractors: for example, the connecting device between the "retractor plate with pull rod" and the "fixed ring" is not "universally adjustable", which leads to the adjustment of the posture of the "retractor plate". Convenience, if the posture of the "retraction plate" cannot be adjusted to the ideal position and posture, some operations may not be...

Problems solved by technology

[0003] There are some disadvantages in the use of traditional multi-directional retractors: for example, the connecting device between the "retractor plate with pull rod" and the "fixed ring" is not "universally adjustable", which leads to the adjustment of the posture of the "retractor plate". Convenience, if the posture of the "retraction plate" cannot be adjusted to the ideal position and posture, some operations may not be completed; and after the "retraction plate with pull rod" is connected with the "fixing ring", the "fixing ring" will still It needs to be connected with the bed frame of the operating table, so that the "retractor plate" can be kept in a fixed state, and there are many steps in the operation process
