Abstract
The utility model discloses a medical reciprocating saw which comprises a saw blade and a casing. The tail of the saw blade is connected with a reciprocating block capable of reciprocating in the casing. The casing is articulated with a transmission lever with an articulating point in the middle; one end of the transmission lever is movably connected with the tail end of the reciprocating slide block, and the other end is movably connected with a radial reciprocating block; a crank shaft for driving the slide block to reciprocate is arranged on the casing; the main shaft of the crank shaft is connected with a driving motor; and the eccentric shaft of the crank shaft is connected with the slide block. Aiming to overcome the defects of the prior art, the utility model provides a medical reciprocating saw which is simple in structure and convenient to use, has high safety performance, low noise and small vibration and operates steadily.
Description
[technical field]
This utility model relates to a kind of medical reciprocating saw.
[background technology]
Medical reciprocating saw is a kind of common tool that carries out the osseous tissue cutting in the surgical operation, needs to realize cutting quickly and accurately osseous tissue.Existing medical reciprocating saw all is to adopt the gear mechanism transmission, and gear drive weares and teares easily and noise is big, vibration is big, and the saw blade kinematic accuracy is not high, and heating is serious, galloping, in operation process safety relatively poor, patient is caused adverse effect.
[utility model content]
This utility model purpose is to have overcome deficiency of the prior art, provides a kind of simple in structure, easy to use, the security performance height, and noise is little, vibrates for a short time, and medical reciprocating saw stably turns round.
This utility model is achieved through the following technical solutions:
A kind of medical reciprocating saw, comprise saw blade, housing, be connected with can be in housing reciprocal past multiblock at the afterbody of saw blade, it is characterized in that being hinged with on the described housing transmission levers of hinge at the middle part, described transmission levers one end is movably connected in the tail end toward multiblock, and the other end is connected with radially reciprocal slide block, and described housing is provided with and drives the reciprocal bent axle of slide block, the main shaft of described bent axle links to each other with drive motors, and the eccentric shaft of bent axle links to each other with slide block.
Aforesaid kind of medical reciprocating saw is characterized in that described housing comprises inner shell, and described inner shell is provided with the radial hole that slide block can reciprocatingly slide within it.
Aforesaid kind of medical reciprocating saw is characterized in that also being provided with on the described inner shell gathering sill, and described is cylinder toward multiblock, and described cylinder afterbody is provided with the guide pad that can slide in radial slot.
Aforesaid kind of medical reciprocating saw is characterized in that described saw blade afterbody is connected with saw handle, describedly is provided with saw handle toward multiblock and can inserts in it and clamped conial chuck.
Aforesaid kind of medical reciprocating saw is characterized in that described conial chuck comprises the inclined-plane folder lip that is arranged on the multiblock, and inclined-plane folder lip is provided with the lock sleeve that the inclined-plane can be pressed from both sides lip locking outward.
Aforesaid kind of medical reciprocating saw is characterized in that described transmission levers with hinged toward multiblock, is provided with waist shape hinge axis hole toward multiblock.
Aforesaid kind of medical reciprocating saw is characterized in that described transmission levers and slide block are hinged, and slide block is provided with waist shape hinge axis hole.
Compared with prior art, this utility model has following advantage:
1, this utility model adopts bent axle slide block and connecting rod slider mechanism, avoids using gear drive, and is simple in structure, easy to use, the security performance height, and noise is little, vibrate for a short time, and running steadily effectively reduces and generates heat.
2, this utility model is provided with guide pad toward the multiblock afterbody, can prevent effectively that the saw blade swing from rocking, and makes its running steadily.

[specific embodiment]
A kind of medical reciprocating saw, comprise saw blade 1, housing 2, be connected with can be in housing 2 reciprocal past multiblock 3 at the afterbody of saw blade 1, be hinged with the transmission levers 4 of hinge on the described housing 2 at the middle part, described transmission levers 4 one ends are movably connected in the tail end toward multiblock 3, and the other end is connected with radially reciprocal slide block 5, and described housing 2 is provided with and drives the reciprocal bent axle 6 of slide block 5, the main shaft 601 of described bent axle 6 links to each other with drive motors 7, and the eccentric shaft 602 of bent axle 6 links to each other with slide block 5.Described housing 2 comprises inner shell 201, and described inner shell 201 is provided with the radial hole 202 that slide block 5 can reciprocatingly slide within it.
Described transmission levers 4 is with hinged toward multiblock 3, describedly is provided with waist shape hinge axis hole 305 toward multiblock 3, vertically steps down in the time of can be to transmission levers 4 reciprocally swingings.Described transmission levers 4 is hinged with slide block 5, and described slide block 5 is provided with waist shape hinge axis hole 505, laterally steps down in the time of can giving transmission levers 4 reciprocally swingings.
Also be provided with gathering sill 203 on the described inner shell 201, described is cylinder toward multiblock 3, and described cylinder afterbody is provided with the guide pad 301 that can slide in radial slot, can effectively prevent saw blade 1 swing, rock.
Described saw blade 1 afterbody is connected with saw handle 101, describedly is provided with saw handle 101 toward multiblock 3 and can inserts in it and clamped conial chuck 8.Described conial chuck 8 comprises the two lobe inclined-planes folder lip 302 that is arranged on the multiblock 3, the inclined-plane folder lip 302 outer lock sleeves 801 that the inclined-plane can be pressed from both sides lip 302 lockings that are provided with.
During use, saw blade 1 is inserted in the conial chuck 8, locking lock sleeve 801, open drive motors 7, drive motors 7 drives bent axle 6 and rotates, the eccentric shaft 601 of bent axle 6 drives slide block 5 and up and down reciprocatingly slides, and slide block 5 drives by connecting rod 4 and reciprocatingly slides toward multiblock about 3, thereby realizes that saw blade about 1 reciprocatingly slides.
