Problems solved by technology

[0002] Condylar sagittal fracture spreader is that when the operator grasps the handle of the forceps, the front end of the spreader will open. The area is narrow, and doctors often use it to open the operation area in order to reset and fix the bone fragments in the operation area. In some cases in the actual medical process, the front end of the spreader often cannot get support at the fracture end to open the operation area. At this time, it is necessary to establish a support at the fracture end. The material used to establish the support is generally a nail. Due to the original structure of the condylar sagittal fracture spreader, the pliers head at the front end of the spreader is easy to slip on the nail. , resulting in the inability of the jaws to obtain stable support on the nails and to propel the surgical area

Embodiment Construction

[0013] Now in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0014] As shown in the figure, it includes a pair of pliers bodies 1 located on both sides and hinged together. The pliers body 1 includes a handle 1a and a front end 1b. The heads of the front ends 1b of the two pliers bodies 1 are bent downward. On the handle 1a of one of the pliers body 1, a positioning rack 2 passing through the handle 1a of the other pliers body 1 is swingably arranged to ensure that the positioning rack 2 is stuck in the hole of the handle 1a of the other pliers body 1 The clamping block 3, through the clamping block 3 and the rack 2, the opening angle of the opening pliers is fixed, such as image 3 As shown, the special feature is that a vertical groove 1d is provided on the outside of the downwardly bent portion 1c of the front end 1b of one of the pliers body 1 .

[0015] like figure 1 As shown, a protruding portion 1f is provi...

Abstract

A surgery opener for sagittal condylar fractures comprises a pair of sub-caliper bodies which are located on the two sides respectively and hinged together. Each sub-caliper body comprises a handle and a caliper head, and the caliper heads of the two sub-caliper bodies are bent downwards. The surgery opener is characterized in that a perpendicular groove is formed on the outer side of the downward-bent part of the caliper head of one sub-caliper body. Compared with the prior art, the surgery opener has the advantages that it can be guaranteed that a caliper jaw can be stably supported on a nail.

Description

Technical field: [0001] The invention relates to a medical device. Background technique: [0002] Condylar sagittal fracture spreader is that when the operator grasps the handle of the forceps, the front end of the spreader will open. The area is narrow, and doctors often use it to open the operation area in order to reset and fix the bone fragments in the operation area. In some cases in the actual medical process, the front end of the spreader often cannot get support at the fracture end to open the operation area. At this time, it is necessary to establish a support at the fracture end. The material used to establish the support is generally a nail. Due to the original structure of the condylar sagittal fracture spreader, the pliers head at the front end of the spreader is easy to slip on the nail. , resulting in the inability of the jaws to obtain stable support on the nails and propel the surgical area. [0003] The purpose of this study is to develop a surgical instr...
