Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] Such as figure 1 , figure 2 As shown, a craniotomy device for anatomy includes an upright frame-type telescopic support 1, the lower part of the telescopic support has support feet 11, and self-locking universal wheels can be arranged on the support feet, which is convenient for movement and can Ensure that the retractable stand is securely positioned when in use. The upper part of the telescopic support is a rectangular frame 12, and the two sides of the supporting legs are fixedly connected with vertically upward support rods 13 respectively. A set screw is screwed, and the tail end of the set screw protruding into the frame leans against the support rod. In this way, when the height of the rectangular frame needs to be adjusted, the set screw can be loosened first, and the rectangular frame can be easily moved up and down along th...

Abstract

The invention discloses a craniotomy device for anatomy. The craniotomy device comprises a stretchy support which is provided with an adjustable head fixing device. The edge of the upper portion of the stretchy support is provided with a plurality of oil cylinders, the two ends of piston rods of the oil cylinders stretch out of cylinder bodies, one end of each piston rod is fixedly connected to the stretchy support, the other ends of the piston rods are fixedly connected into a whole through a connecting support, rail plates fixedly connected with the cylinder bodies of the oil cylinders are vertically arranged among the oil cylinders, the rail plates are concentrically provided with at least two circles of cutting rail ring grooves which are internally provided with a plurality of partition blocks, the partition blocks are integrated with the rail plates so that the cutting rail ring grooves can be divided into a plurality of saw web guiding grooves, the saw web guiding grooves are internally and transversely provided with movable saw web fixing rods, one end of each saw web fixing rod is provided with a saw web shaft, one end of each saw web shaft is fixedly connected with a saw web, and the other end of each saw web shaft is connected with a power source through a transmission flexible shaft. According to the craniotomy device, working efficiency is high, operation is convenient, and the meninx tissues in the skull can be effectively prevented from being injured.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a craniotomy device for dissection. [0002] Background technique [0003] At present, craniotomy during dissection is mostly done with some simple manual or electric tools, such as electric craniotomy drills, craniotomy mills, manual rongeurs, surgical hammers, etc. These tools are not only time-consuming and labor-intensive to use, but also The depth of drilling and milling is difficult to control, and requires high skill and experience of anatomists. Now there is a kind of electric craniotomy saw, which has a shell that can be held by hand. The front end of the shell has a shaft sleeve that can be held by hand. The shaft sleeve is provided with a rotatable knife rod. There is a saw blade at the end. When the skull is cut by the saw blade, the saw blade will automatically stop cutting, so as to avoid damage to the meningeal tissue in the skull. However, this type of electric craniotomy...
