Abstract
The utility model relates to the technical field of medical instruments, in particular to a torsion handle. The torsion handle comprises a T-shaped silica gel handle body. A pushing rod is arranged in the silica gel handle body, a movable ratchet wheel and a device for fixing the ratchet wheel are arranged on the pushing rod, and the movable ratchet wheel and the device for fixing the ratchet wheel are installed on a connection fixing base in an integrated mode. The tail end of the device for fixing the ratchet wheel is provided with a quick-replacing connector. The length L of the silica gel handle body is 129mm. The outer layer of the silica gel handle is made of silica gel and the inner core of the silica gel handle is made of aluminum materials. The torsion value of the torsion handle is 11Nm to 12.6Nm. In addition, the size and the weight of the torsion handle are also reduced, and a doctor can conveniently operate and carry the torsion handle.
Description
Technical field
The utility model relates to technical field of medical instruments, especially a kind of torque handle.
Background technology
Medically, need pedicle screw in bone surgery clinically, need to use torque handle by screw-driving.Existing decreased food is 141mm, and the handle inner core is stainless steel, and quality is heavier, during use, can produce top-heavy phenomenon.
The utility model content
In order to overcome the deficiency of existing technology, the utility model provides a kind of torque handle.
The utility model solves the technical scheme that its technical problem adopts: a kind of torque handle, comprise T-shaped silicon handle, push rod is installed in silicon handle, be provided with the assembling of moving ratchet and fixed ratchet wheel on push rod, the assembling of moving ratchet and fixed ratchet wheel is one and is arranged on connection fixing base, and the end of the assembling of fixed ratchet wheel is provided with rapid replacing interface, and described silicon handle length L is 129mm, described silicon handle skin is silica gel, and inner core is the aluminium material.
According to another embodiment of the present utility model, further comprise between described push rod and moving ratchet and being connected by the butterfly shell fragment.
According to another embodiment of the present utility model, further comprise that described moving ratchet end is provided with threaded closure caps, the threaded closure caps outside is coated with outer tube, and outer tube is by the assembling close fit of sealing ring and fixed ratchet wheel.
The beneficial effects of the utility model are that the utility model volume and quality reduce simultaneously, are convenient to doctor's operation and carry.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model;
In figure 1, silicon handle, 2, fixed connecting base, 4, outer tube, 5, threaded closure caps, 6, sealing ring, 7, the assembling of fixed ratchet wheel, 8, rapid replacing interface, 10, moving ratchet, 12, the butterfly shell fragment, 14, push rod.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of torque handle, comprise T-shaped silicon handle 1, push rod 14 is installed in silicon handle 1, be provided with the assembling 7 of moving ratchet 10 and fixed ratchet wheel on push rod 14, the assembling 7 of moving ratchet 10 and fixed ratchet wheel is one and is arranged on connection fixing base 2, and the end of the assembling 7 of fixed ratchet wheel is provided with rapid replacing interface 8, for welding with hydraulic quick coupler.Described silicon handle 1 length L is 129mm, and described silicon handle 1 skin is silica gel, and inner core is the aluminium material, and decreased food shortens, and handle inner core part material is changed simultaneously, and the material of existing design is ADC12, is 1/3 left and right of handle quality in early stage.Between described push rod 14 and moving ratchet 10, by butterfly shell fragment 12, be connected.Described moving ratchet 10 ends are provided with threaded closure caps 5, and threaded closure caps 5 outsides are coated with outer tube 4, and outer tube 4 is assembling 7 close fit with fixed ratchet wheel by sealing ring 6.
The utility model torque value scope is 11 ~ 12.6Nm, and volume and quality reduce simultaneously simultaneously, are convenient to doctor's operation and carry.
