Referring to fig. 1 to 4, the present invention provides an embodiment: the utility model provides a slight bone drill of pen type hand for bone surgery, including drill bit 1, protection casing 2, dwang 3, grab handle 4, motor 5, miniature air pump 6 and block rubber 7, 4 internally mounted of grab handle have motor 5 and miniature air pump 6, motor 5 adopts YS-3420 type, miniature air pump 6 adopts ZQ520-02 type, this model motor 5 and miniature air pump 6 possess small, the rotational speed is fast and the fast advantage of air exhaust speed, can satisfy the needs of in-service use, look for affiliated technical staff through the model and directly purchase on market, can directly look over when needing to know this model equipment and look for the technical specification and know, consequently this equipment is not repeated. Motor 5 is located 6 one sides of miniature air pump, motor 5 is connected with 4 inner walls of grab handle through the fixed block 10 of symmetric distribution with 6 outer walls of miniature air pump, grab handle 4 deviates from 5 one side outer walls imbeds of motor and installs rubber block 7, 7 inside peggings of rubber block have power cord 8, power cord 8 is connected with motor 5 and 6 electricity of miniature air pump, rubber block 7 can carry on spacingly and the protection to power cord 8, prevent that power cord 8 from appearing fracture and damage in 4 edges of grab handle.

Motor 5 deviates from the rotation of 6 one sides outer walls of miniature air pump and installs dwang 3 that runs through the 4 outer walls of grab handle, dwang 3 deviates from the rotation of 5 one ends of motor and installs drill bit 1, screw 15 has been seted up to 1 one side of drill bit inside, and 3 one end outer walls of dwang set up the screw 16 with 15 looks adaptations of screw, drill bit 1 passes through screw 15 and screw 16, drill bit 1 can be nimble installs the one end at dwang 3, screw 16's direction is the same with dwang 3 direction of rotation, when dwang 3 drives drill bit 1 and rotates, the pine can not appear in drill bit 1, medical personnel only need to revolve drill bit 1 through screw 16 down, only change drill bit 1, and is convenient and fast more, need not to change whole drill bit 1 and dwang 3, thereby the time. 3 outer walls of dwang have cup jointed slider 14, slider 14 is inside to have seted up through- hole 17, and 3 pegs graft inside through-hole 17 of dwang, 14 one side outer wall of slider is fixed with protection casing 2 that the semicircular in shape distributes, 2 inner wall diameters of protection casing are greater than 1 outer wall diameter of drill bit, slider 14 deviates from 1 one side outer wall of drill bit and passes through spring 11 and 4 one side outer wall elastic connection of grab handle, spring 11 makes protection casing 2 at 3 surface sliding of dwang through self elasticity, make one side of protection casing 2 keep laminating with patient's bone wall surface, thereby it can carry out the cage to the drilling region to have ensured protection casing 2, the effect of bone bits is collected in the guarantee, because protection casing 2 adopts semicircular distribution, the drilling effect is observed to the opening part of medical.

2 one side outer walls of protection casing are pegged graft and are had material 13 of inhaling, it runs through 4 outer walls of grab handle and is connected with miniature air pump 6 to inhale material pipe 13 one end, 6 one side outer walls of miniature air pump are pegged graft and are had the discharge pipe 9 that runs through 4 outer walls of grab handle, when drilling 1 drills, protection casing 2 slides on dwang 3 through spring 11's elasticity, one side of protection casing 2 can contact with patient's bone wall, the inside impeller of miniature air pump 6 during operation rotates and can produce the negative pressure, the negative pressure is through inhaling inside pipe 13 conduction to protection casing 2, 2 half cage covers of protection casing are regional at the drilling, during drilling, the bone bits can spill over 1 outer wall of drill bit, the negative pressure that miniature air pump 6 produced can inhale the regional bone bits of drilling, and discharge through discharge pipe 9, thereby the purpose of collecting is carried out to the bone bits that the drilling produced, prevent. The button 12 is installed in the embedding of 4 one ends outer walls of grab handle, and button 12 is connected with the circuit electricity of motor 5 and miniature air pump 6, and medical personnel can hand grab handle 4, carries out work through pressing button 12 control motor 5 and miniature air pump 6 to carry out drilling operation.

The working principle is as follows: medical personnel can hold the grab handle 4 by hand, the motor 5 and the micro air pump 6 are controlled to work by pressing the button 12, the motor 5 drives the drill bit 1 to rotate, the drill bit 1 is enabled to drill on the bone wall of a patient, meanwhile, the spring 11 enables the protective cover 2 to slide on the surface of the rotating rod 3 through self elasticity, one side of the protective cover 2 is enabled to be kept attached to the surface of the bone wall of the patient, thereby ensuring that the protective cover 2 can cover a drilling area and ensuring the effect of collecting bone fragments, because the protective cover 2 adopts semicircular distribution, the medical personnel can observe the drilling effect through the opening of the protective cover 2 without influencing the actual operation, when the micro air pump 6 works, the impeller inside rotates to generate negative pressure, the negative pressure is transmitted to the inside of the protective cover 2 through the suction pipe 13, the protective cover 2 is covered on the drilling area in a half way, when the bone fragments are drilled, the outer wall of the drill bit 1 can, and is discharged through the discharge pipe 9, thereby achieving the purpose of collecting bone fragments generated by drilling and preventing the bone fragments from influencing the process of the operation and the wound healing effect of a patient.

Before carrying out actual operation, medical personnel can change drill bit 1 according to actual operation's the condition, drill bit 1 passes through screw 15 and screw thread 16, drill bit 1 can be nimble install the one end at dwang 3, the direction of screw thread 16 is the same with dwang 3 rotation direction, when dwang 3 drives drill bit 1 and rotates, the pine takes off can not appear in drill bit 1, medical personnel only need to revolve down drill bit 1 through screw thread 16, only change drill bit 1, and is convenient and fast more, need not to change whole drill bit 1 and dwang 3, thereby the time of changing drill bit 1 has been saved.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
