Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a handheld medical electric hammer device. Background Art

[0002] Bone hammer is a common medical device, mainly used for bone processing in orthopedic surgery. Bone hammer is generally composed of a handle and a hammer head. The handle is generally made of metal material, and the hammer head is made of harder materials, such as stainless steel. It is divided into three types according to weight: light, medium and heavy. Light type is mainly used for finger, toe bone and small joint surgery; medium and heavy types are mainly used for limb and spine surgery. In orthopedic surgery, bone hammer can be used for a variety of operations, such as knocking bones, adjusting bone positions, etc. However, the use of bone hammer requires special caution. Before using the bone hammer, the doctor needs to disinfect the bone hammer. Disinfection can generally be carried out by high-temperature steam disinfection or chemical disinfection, which can effectively kill microorganisms such as bacteria and viruses. In addition, because the operation of the bone hammer requires great force, some improper operations may cause bone fracture or dislocation. Therefore, doctors need to master the use of bone hammer very skillfully, and also pay attention to the strength and direction of the operation to avoid unnecessary harm to patients. In addition to using bone hammers in surgery, bone hammers can also be used in some other medical operations. For example, when resetting a fracture, doctors can use bone hammers to help restore the normal position of the bones. At this time, doctors need to use imaging techniques such as X-rays to assist in the operation to ensure the accuracy and safety of recovery.

[0003] In addition to the risk of causing harm to patients due to improper use or unskilled operation, the bone hammer also has the risk of unsuccessful surgery due to the difficulty in maintaining consistent striking force and direction. In addition, the use of a bone hammer consumes a lot of the doctor's physical strength, which not only increases the difficulty of the doctor's surgery, but also affects the doctor's physical and mental health. Therefore, a handheld medical electric hammer device is invented. Summary of the invention

[0112] The tool clamping system 30000 includes: a hammer block 31000, a transverse slide 32000, a pulling lever 33000, a tool base 34000 whose inner cavity is provided with a tool, and a housing 35000;

[0113] The outer cylinder 23000 is fixedly installed on the left side of the shell 35000, and the left side of the shell 35000 is slidably connected to the hammer block 31000. The hammer block 31000 is provided with a spring, and the spring is located between the head of the hammer block 31000 and the left side of the shell 35000. Both sides of the shell 35000 are slidably connected to the transverse slider 32000 through the guide rail. Both ends of the right side of the shell 35000 are rotatably connected to the pulling lever 33000, and the inner side of the left end of the pulling lever 33000 is in contact with the transverse slider 32000.

[0114] When using it, the specific steps are as follows:

[0115] In the initial state, the magnet 21200 is attracted to the upper magnetic cover plate 22100. Then, the controller 13000 controls the motor 15000 to drive the speed reduction mechanism 16000 through the button 14000. At this time, the piston shaft 22400 is moved through the cooperation of the first speed reduction bevel gear 17000, the first crank wheel 17100 and the first connecting rod 17200, so that the piston 22220 can be used to compress the fluid in the main cylinder body 22210. When the compression reaches the limit, the magnet 21200 and the upper magnetic cover plate 22100 are separated, so that the hammer cylinder 22000 can hit the hammer block 31000 at a higher speed. After the impact, the hammer system 20000 can be restored to its original position through the driving system 10000 to prepare for the next impact.

[0116] When the electric hammer is in the hammering state, the tool is pressed against the object to be hammered, and then the tool base 34000 and the hammer block 31000 are pressed together. At this time, the hammer block 31000 is in the leftmost initial position. When the hammer cylinder 22000 hits the hammer block 31000, the hammering force is transmitted to the tool base 34000 and the tool, thereby realizing the hammering function. In this process, the horizontal slider 32000 and the pulling lever 33000 do not work;

[0117] When the electric hammer is in the pulling state, the tool and the object to be pulled out are in a tensioned state, and the tool will pull the tool base 34000 toward the object to be pulled out. At this time, the tool base 34000 will contact the pulling lever 33000, and then the pulling lever 33000 will push the horizontal slider 32000 to the center position until it contacts the tail of the tool base 34000. At this time, the hammer block 31000 is in the leftmost initial position due to its own spring; when the hammer cylinder 22000 hits the hammer block 31000, the hammer block 31000 moves forward, hits the horizontal slider 32000, and squeezes the horizontal slider 32000 to both sides, so that the horizontal slider 32000 pushes the pulling lever 33000, so that the tool base 31000 can be pushed to the left through the pulling lever 33000, thereby driving the tool to realize the pulling function.
