Abstract

The invention discloses an intelligent perforating device suitable for different wall thicknesses. The intelligent perforating device comprises a supporting frame and a controller. A cutting mechanism for perforating, a rotating mechanism for driving the cutting mechanism to move along a set track, a lifting mechanism for driving the cutting mechanism to be lifted and a pressure sensor for detecting the pressure borne by the cutting mechanism are installed in the supporting frame. The controller is used for receiving a pressure signal of the pressure sensor and meanwhile controlling the cutting mechanism, the rotating mechanism and the lifting mechanism according to the pressure signal. The intelligent perforating device is simple in structure, low in manufacturing cost, convenient to operate and high in intelligence integration level, holes can be automatically manufactured according to design requirements under the premise that tissue structures below bone walls are not injured, and the sizes of holes are adjustable.

Description

technical field

[0001] The invention relates to a punching device, in particular to an intelligent punching device adapted to different wall thicknesses on thin-walled bones and skulls of animals. Background technique

[0002] In the field of industrial applications, there are many punching equipment for making holes, and the technology is very mature, but in the field of biomedicine, there are very few related equipment, because the punching in the biomedical field is to punch living organisms, After the hole is completed, it is necessary to ensure that the organism is alive, which is completely different from the industrial field. For example, the craniotomy operation that is very common now is to open a hole in the skull of an animal. The meninges and brain tissue are located under the skull. If you use the conventional method to operate, only the shape and size of the hole are considered, and there is not much control on the depth. , it is possible to destroy the brain ...

Examples

Embodiment

[0086] It is an example to make the hole of 8mm in diameter on the rabbit calvaria, to illustrate the working process of the device of the present invention:

[0087] 1. Take a rabbit weighing between 2.5 and 3.5kg, inject a certain dose of general anesthesia reagent into the rabbit's ear vein to perform general anesthesia on the rabbit, and then shave the rabbit's calvaria. On the operating table, tie up its four legs, sterilize the shaved area with povidone iodine, and then spread a drapery and incise the skin with surgical instruments to expose the position of the calvaria to be punched;

[0088] Two, loosen the set screw on the slide block, adjust the slide block to the position where the radius is 4mm, then tighten the set screw, the blade that has been sterilized in advance is installed on the punching device of the present invention, and the blade near the blade The cutting mechanism is disinfected with povidone iodine, and then the device is placed on the operating tab...
