Technical Field

The invention relates to the field of surgical medical instruments, in particular to an auxiliary device for fracture treatment and a treatment method thereof.

Background

There are three major principles for treating fracture, namely reduction, fixation and functional exercise. Wherein, the reduction comprises manual reduction and operation reduction, which is to restore the normal or nearly normal anatomical relationship of the displaced fracture section and rebuild the support function of the bone. Is the primary step for treating fracture and also is the basis for fracture fixation and functional exercise. Early correct reduction is a necessary condition for smooth progress of the fracture healing process. Secondly, the fixation is to maintain the fractured bone at the position after the reduction, so that the fractured bone can be firmly healed under the condition of good alignment, and is the key of fracture healing.

Because the correct position of the fractured bone needs to be kept for fixation, when the fixing device is installed, medical workers hold tools such as a towel clamp and the like for a long time to fix the fractured part, and large physical strength is consumed; meanwhile, shaking is likely to occur in the maintaining process, so that position deviation is caused, and the subsequent operation effect and the recovery effect of the patient are affected.

Disclosure of Invention

The invention provides an auxiliary device for treating fracture, which relieves the fatigue of medical workers holding tools for a long time in the operation process and solves the problems of inaccurate and unstable holding and positioning for a long time.

In order to solve the technical problems, the technical scheme provided by the invention is as follows: an auxiliary device for treating fracture comprises a positioning clamp, a fixing block, a connecting part and a locking device. The positioning clamp is arranged on one plane of the fixing blocks, and the adjacent fixing blocks are connected through a connecting part. The connecting part comprises a base and a connecting column, and the base and the connecting column are respectively arranged on two side vertical surfaces of the fixing block; the locking device is arranged on the other plane of the fixed block in a matching mode and locks a plurality of fixed blocks.

The base of the connecting part comprises a spherical shell and a bottom plate, and the bottom of the spherical shell is fixed on the bottom plate; one end of the connecting column is provided with a ball body which is in clearance fit with the ball shell of the adjacent fixed block. The fixing blocks are connected with each other through the connecting parts, have freedom degrees in multiple directions, and are more suitable for positioning in fracture operations of different parts on human bodies.

The locking device comprises a rigid fixing plate, and a limit baffle is arranged on one side of the rigid fixing plate matched with the fixing block. The rigid fixing plate can be used for parts of long bones and other bones with lines similar to straight lines; spacing baffle interval suit with the specification of fixed block, press from both sides the position of location after confirming with spacing baffle and fixed block cooperation, supplementary fracture's position recovers, has strengthened the stability of fixed block and location clamp.

Preferably, the fixing block can be arranged as a limiting baffle made of elastic materials and used for clamping the fixing block; the limiting baffle plate can also be made of non-elastic materials and slides in from the fixing block positioned at the head end or the tail end, so that the locking effect of the rigid fixing plate is realized.

The locking device also comprises a clamp arranged on the other side of the fixed block, and the clamp is movably connected with the fixed block. During the treatment, if for health parts such as clavicle take place the fracture, medical personnel get the skeleton model at same position and grasp with the clamp on a plurality of fixed block according to predetermined fixed point in proper order, connect the back through connecting portion between the adjacent fixed block, grasp the fracture with the locating clip that the below corresponds again, play the effect of temporary fixation.

Preferably, a lifting adjusting device is arranged between the clamp and the fixing block, so that medical staff can adjust the position and the rotating angle of the clamp in the vertical direction according to the bone shapes of different parts, the position of the fracture treatment assistor is consistent with the normal bone position, and the fracture treatment assistor is more flexibly suitable for various types of fracture treatment operations.

Preferably, the locking device and the fixing block are correspondingly provided with through holes, so that a doctor can conveniently penetrate internal fixing tools used in fracture treatment such as a Kirschner nail and the like from the through holes, and the accuracy of skeleton reduction and fixation is improved.

Further, the positioning clamp comprises a first clamping part and a second clamping part, and the two clamping parts are arc-shaped; first clamping part and second clamping part symmetry set up on the fixed block, pass through bolted connection with the fixed block, when the treatment to different positions fracture, can replace into corresponding specification.

The invention also provides a treatment method which comprises the following steps: determining the position of the fractured bone during the fracture treatment, and reducing the fractured bone in a traction manner; a plurality of fixing blocks with positioning clamps are used for clamping and fixing, and a plurality of separated fixing blocks are matched and connected with connecting columns through bases positioned on two sides, so that the preset position and angle of the fractured bone before surgical fixation are ensured; and a locking device is arranged on the other side of the connected group of fixed blocks in a matching way, and then the skeleton is fixed.

Specifically, when fracture treatment is performed, medical staff firstly determine the position of a fractured bone in a normal state; then clamping the fractured bone by the fixing block provided with the positioning clamp, connecting the fixing blocks by matching a ball body and a spherical shell in the connecting part, adjusting the position of the positioning clamp by a doctor through the angle of the connecting part in the adjusting process, and finally fixing the position of the fractured bone by the fixing block provided with the positioning clamp; and then, the locking device is matched with the fixed blocks to lock the plurality of separated fixed blocks and fix the positions of the plurality of fixed blocks. Based on the position, medical personnel can carry out the operation of internal fixation or external fixation on the folded bone by steel nails, steel plates, plaster and the like in the next step.

Compared with the prior art, the invention has the substantial characteristics that: the position of the fractured bone is determined by the plurality of separable positioning clamps, and the plurality of separated fixing blocks with the positioning clamps are connected by the locking device, so that the accuracy of resetting and fixing in fracture treatment is improved, the labor intensity of medical workers in the operation is greatly reduced, the efficiency of the operation is improved, and the treatment effect on the patient is better ensured; the device has simple structure, convenient manufacture and low cost, is easy to operate by medical personnel, and can be suitable for wider patient groups.
