Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of scalpel with supplemental support.
Background technology
At present, the employed scalpel of department of general surgery mainly is to be made of cutter hub and handle of a knife clinically, this scalpel is when performing the operation to patient, the weight of surgical cut is difficult to control, can only rely on medical worker's working experience to operate, this just requires the operator to have higher level, has increased work difficulty to the medical worker.When doing precise and tiny operation, the shake of wrist may cause very serious consequence, so can realize accurate cutting, easy to operate scalpel is that operating doctor is desired.Patent publication No. CN201631326U discloses a kind of scalpel, and it comprises cutter hub and handle of a knife, and feature is to be provided with scale on the cutter hub surface, and the cutter hub root is provided with curved boom, and curved boom is provided with sleeve pipe, and sleeve pipe is provided with navigation button, and the sleeve pipe front end is provided with the location holder.This structure is to locate holder with respect to the length of point of a knife by regulating, thus the weight of control cutting.But there is malfunction in this scalpel, and the location holder has formed obstacle when carrying out degree of depth cutting, use inconvenience.
The utility model content
The defects that exists for solving prior art, it is a kind of easy to operate that the purpose of this utility model is to provide, and can accurately control the scalpel with supplemental support of the cutting depth.
For achieving the above object, the technical solution adopted in the utility model: this has the scalpel of supplemental support, have cutter hub and handle of a knife, it is characterized in that: be hinged with supplemental support on the described handle of a knife, described supplemental support is passed the ring support that is positioned on the handle of a knife, be provided with positioner between ring support and the supplemental support, described positioner has and is positioned at location depression uniform on the ring support, the card bead that corresponding ring support position cooperates with the location depression on the supplemental support, by spring supporting, spring and card bead are positioned at the installing hole on the supplemental support under the card bead.
Described handle of a knife is provided with anti-skidding band.
Adopt the beneficial effect of technique scheme: this has on the handle of a knife of scalpel of supplemental support and is hinged with supplemental support, supplemental support turns an angle in use, make cutter hub and supplemental support be herringbone, the angle of supplemental support and cutter hub folding can be controlled the depth of cutter hub cutting.Handle is provided with ring support, is provided with positioner between ring support and supplemental support, and the rotation supplemental support can realize the self-locking of locating, accurate positioning, and the cutter hub cutting depth is accurately controlled.Supplemental support can make the unsettled arm of operator be supported in the process of using, and operation is sane, has reduced to be subjected to the impact of experience level, thereby has ensured carrying out smoothly of operation.Carrying out deep layer when cutting, supplemental support is being rotated top to handle, making it not affect tissue cutting.So this scalpel with supplemental support has compact conformation with respect to prior art, the depth is accurately controlled, and is easy to operate, reduces the impact of empirical factor, for the success of cutting operation provides guarantee.
Description of drawings
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the user mode figure when cutting than deep layer.
