Embodiment 1

[0025] A kind of gypsum trimmer for orthopedic limb fixation, such as Figure 1-2 As shown, it includes a mounting plate 1, a handle 2 and a protective shell 3. The handle 2 is connected to the mounting plate 1, and the protective shell 3 is connected to the left side of the mounting plate 1. It also includes a driving mechanism 4, a shearing mechanism 5 and a penetrating mechanism. Mechanism 6, a driving mechanism 4 is provided between the installation disk 1 and the protective shell 3, a penetrating mechanism 6 is provided on the installation disk 1, a shearing mechanism 5 is provided between the driving mechanism 4 and the probing mechanism 6, and the shearing mechanism 5 It is transmission connected with the drive mechanism 4.

[0026] The drive mechanism 4 includes a geared motor 41, a cam 42 and a connecting plate 43. The geared motor 41 is installed on the right side of the mounting plate 1. The output shaft of the geared motor 41 passes through the mounting plate 1 and...

Embodiment 2

[0031] On the basis of Example 1, such as image 3 As shown, it also includes a stretching mechanism 7, and the stretching mechanism 7 includes a fixed block 72, a slide bar 73, a second spring 74 and an arcuate push plate 75, and the front side of the contact rod 51 has an oblique opening 71, and the insertion plate 61 The middle part is connected with fixed block 72, is connected with slide bar 73 on the fixed block 72, is connected with arc push plate 75 slidingly on the slide bar 73, is connected with second spring 74 between arc push plate 75 and fixed block 72, arc The face push plate 75 cooperates with the oblique opening 71 .

[0032] The contact bar 51 can push the arcuate push plate 75 to move to the right through the bevel 71 when moving downwards, the second spring 74 is stretched, and the arcuate push plate 75 moves to the right to scrape off the cut gypsum, so that it can avoid The gypsum that has not been cut and the gypsum that has been cut stick together and ...

Abstract

The invention relates to a trimmer, in particular to a gypsum residual trimmer for orthopedic limb fixation. The technical problem to be solved by the present invention is how to provide a gypsum trimmer for orthopedic limb fixation that can ensure the safety of patients during operation. In order to solve the above technical problems, the present invention provides such a gypsum trimmer for orthopedic limb fixation, which includes: a mounting plate, on which a handle is connected; a protective shell, which is connected to one side of the mounting plate; a driving mechanism, which It is arranged between the installation disk and the protective shell; the shearing mechanism is arranged on the installation disk; the penetrating mechanism is arranged between the driving mechanism and the probing mechanism, and the shearing mechanism and the driving mechanism are connected by transmission. The invention trims the gypsum through the cooperative operation of the driving mechanism and the shearing mechanism, so as to achieve the effect of trimming the gypsum.

Description

technical field [0001] The invention relates to a trimmer, in particular to a gypsum residual trimmer for orthopedic limb fixation. Background technique [0002] Gypsum is a monoclinic mineral, a hydrate whose main chemical composition is calcium sulfate. Gypsum is a versatile industrial and construction material. It can be used in cement retarder, gypsum building products, model making, medical food additive, sulfuric acid production, paper filler, paint filler, etc. The microporous structure and heating dehydration of gypsum and its products make it have excellent sound insulation, heat insulation and fireproof performance. Plaster is mostly used to fix limbs after fractures. After the plaster is used, there is usually some excess material on the side, which is easy to rub against the skin at the edge of the wound and easily cause infection. The remaining material needs to be trimmed. [0003] At present, the method of trimming the remaining gypsum is usually to align t...
