Problems solved by technology

[0002] The internal fixation of the traditional hollow nail is to use temporary steel needles to maintain the reduction of the bone block, which cannot achieve the compression effect at the same time; the guide pin needs to be repeatedly examined under fluoroscopy, which not only consumes radiation and is time-consuming, but also easily breaks the bone block and affects the internal fixation Intensity; and often the needle exit point is not ideal; the depth measurement is often due to soft tissue interference or the depth sounder is too thin to accurately hang on the opposite side, and the reading is inaccurate; pull out the guide needle during depth measurement, and it is difficult to enter the guide needle again, etc.

Embodiment 1

[0024] A reset guide, which includes a handle 1 and a guide, a parallel pressurizing device is arranged between the handle 1 and the guide, the guide includes a needle guide assembly 11 and a blocking head 6, and the needle guide assembly 11 and the blocking head 6 are arranged correspondingly . One section of the parallel pressurizing device is arranged on the front end of the handle, which is a horizontal beam 9 at an obtuse angle with the handle, and a centrally hinged connecting rod 2 is arranged between the beams 9, and an adjusting hole 8 is arranged at one end of the connecting rod 2, and the adjusting hole 8 is arranged as two ends and The connecting rod 2 matches, and the middle distance matches the shape of the parallel space of the connecting rod 2, and the connecting rod 2 can slide back and forth along the adjusting hole 8. The guide is arranged at one end of the parallel pressurizing device, and the needle insertion guide assembly 11 and the blocking head 6 are r...

Embodiment 2

[0026] The difference between this embodiment and Embodiment 1 is that this embodiment is not provided with a positioning device.

Embodiment 3

[0028] The difference between this embodiment and Embodiment 1 is that the depth scale is not provided in this embodiment, and the depth of needle insertion is monitored through perspective during the operation.

Abstract

The invention relates to the technical field of medical instruments, in particular to a reset guider, and aims at providing the reset guider which not only can perform pressurization, but also can perform reset, drives a guide needle into a bone block, measures the depths of screwed bolts, and finally fixes the bone block. The reset guider comprises a handle and a guider body, wherein a parallel pressurization device is arranged between the handle and the guider body, the guider body comprises a needle inlet guide assembly and a blocking head, and the needle inlet guide assembly and the blocking head are correspondingly arranged. The reset guider can assist in reset and more importantly can perform pressurization, so that the bone block is not separated any more, and fracture healing and the recovery of articular surface leveling are facilitated; repeated needle threading is not needed to avoid iatrogenic injuries; after pressurized fixation, the guide needle can be directly driven, the length is read, a first inner sleeve is taken out, a channel is drilled directly and hollowly, then a second inner sleeve is taken out, and a hollow nail with the measured length is directly screwed, thereby saving the operation time; since the length of the part entering the bone substance is the same as the automatic depth measurement scale, the measurement is accurate.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a reset guide. Background technique [0002] The internal fixation of the traditional hollow nail is to use temporary steel needles to maintain the reduction of the bone block, which cannot achieve the compression effect at the same time; the guide pin needs to be repeatedly examined under fluoroscopy, which not only consumes radiation and is time-consuming, but also easily breaks the bone block and affects the internal fixation Intensity; and the needle exit point is often not ideal; the depth measurement is often due to soft tissue interference or the depth sounder is too thin to accurately hang on the opposite side, resulting in inaccurate readings; pulling out the guide needle during depth measurement makes it difficult to enter the guide needle again. With the continuous improvement of patients' requirements for prognosis, the level of medical care is constantly im...
