Description

Medical dissection saw
Technical Field
The invention relates to the field of medical sawing drills, in particular to a medical dissection saw.
Background
Medical equipment is an important tool in the medical operation process and mainly comprises a craniotomy drill, a sternum saw, a swing drill and the like. The medical anatomy is needed to dissect the skin of a human body, but some parts of the human body have bones, and if the bones are dissected, the human body is damaged, so the bones are needed to be avoided dissecting. This problem is therefore necessary.
Disclosure of Invention
In order to solve the problems, the invention provides a medical dissection saw, wherein a motor drives an eccentric shaft to rotate, the eccentric shaft drives a main shaft to rotate, the main shaft is connected with a saw head of a saw blade, so that dissection operation is performed, once the saw blade saws a bone, the saw blade bears upward resistance, and after the main shaft senses the resistance, a shifting fork can shift the eccentric shaft to disconnect the eccentric shaft from a connecting sleeve, so that the bone is prevented from being sawed, safety is well ensured, and the problems in the background technology are solved.
The invention aims to provide a medical dissection saw, which comprises a shell, wherein a motor is arranged in the shell, the left side of the motor is connected with a connecting tooth, the left side of the connecting tooth is connected with an eccentric shaft, and the motor drives the eccentric shaft to rotate through the connecting tooth; a connecting sleeve is connected above the eccentric shaft in a meshed manner, the left side of the connecting sleeve is connected with a main shaft, and the eccentric shaft drives the main shaft to rotate through the connecting sleeve; a shifting fork penetrates through the right end of the main shaft, and the shifting fork is in contact with the eccentric shaft and can shift the eccentric shaft; the main shaft extends out of the machine shell leftwards, the left side of the main shaft is connected with a saw head, and a saw blade is arranged in the middle of the saw head.
The further improvement lies in that: and a shaft sleeve is arranged on the outer side of the part of the main shaft outside the machine shell.
The further improvement lies in that: both sides are connected with fast socket and toggle switch respectively about the motor right side, insert socket and toggle switch soon and all stretch out right and lie in outside the casing.
The further improvement lies in that: an anti-slip layer is arranged outside the shell.
The invention has the beneficial effects that: the motor drives the eccentric shaft to rotate, the eccentric shaft drives the main shaft to rotate, and the main shaft is connected with the saw head of the saw blade, so that the dissection operation is performed.

Detailed Description
For the purpose of enhancing understanding of the present invention, the present invention will be further described in detail with reference to the following examples, which are provided for illustration only and are not to be construed as limiting the scope of the present invention.
As shown in fig. 1, the present embodiment provides a medical dissection saw, which includes a casing 1, a motor 2 is disposed in the casing 1, a connecting tooth 3 is connected to the left side of the motor 2, an eccentric shaft 4 is connected to the left side of the connecting tooth 3, and the motor 2 drives the eccentric shaft 4 to rotate through the connecting tooth 3; a connecting sleeve 5 is connected above the eccentric shaft 4 in a meshed manner, a main shaft 6 is connected to the left side of the connecting sleeve 5, and the eccentric shaft 4 drives the main shaft 6 to rotate through the connecting sleeve 5; a shifting fork 7 penetrates through the right end of the main shaft 6, and the shifting fork 7 is in contact with the eccentric shaft 4 to shift the eccentric shaft 4; the main shaft 6 extends out of the machine shell 1 leftwards, the left side of the main shaft 6 is connected with a saw head 8, and a saw blade 9 is arranged in the middle of the saw head 8. The spindle 6 is provided with a shaft sleeve 10 at the outer side of the part outside the machine shell 1. Both sides are connected with fast socket 11 and toggle switch 12 respectively about the motor 2 right side, and fast socket 11 and toggle switch 12 all stretch out to the right and are located outside casing 1. An anti-slip layer 13 is arranged outside the casing 1.
Drive eccentric shaft 4 through motor 2 and rotate, eccentric shaft 4 drives main shaft 6 and rotates, and main shaft 6 is connected with saw head 8 of saw bit 9 to dissect the operation, in case when saw bit 9 saw the bone, can receive ascending resistance, after main shaft 6 experienced, eccentric shaft 4 made eccentric shaft 4 and adapter sleeve 5 disconnection just can be stirred to shift fork 7, thereby avoid sawing the bone, fine assurance safety.
