Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly the disposable scalpel of one.
Background technology
In Chinese patent database, disclose a kind of disposable safe scalpel, its application number: 201410228377.2; The applying date: 2014-05-27; Publication number: 103976776A; Publication date: 2014-08-13, this disposable safe scalpel is made up of blade, handle of a knife and broach shell, when the relative handle of a knife slide anteroposterior of broach shell and when locating, blade presents and stretches out and retraction two states from broach shell, first locking port is set in the knife-protecting lock port front of handle of a knife reverse side, between knife-protecting lock port and the first locking port, carries out transition by inclined-plane or arc surface; In the front of handle of a knife front through slot, the second locking port and stopper are set.Under button is in pressed state, during driven forward broach shell, due to ram tackle by stopper cannot make to ram from through slot front end and slide onto the second locking port, effectively prevent scalpel and not yet use the situation being just pushed into locking state.In addition, can not there is the phenomenon of slippage in state stuck while of front-back two-sided, thus ensure that the stability of locking state well because of the excesssive gap between broach shell and handle of a knife and distortion.Its weak point is: 1, its protective sleeve is in the process of sliding, and button point has the possibility of fracture, and is exposed to outside, very easily produces malpractice.2, the use length of blade cannot regulate and control, and is that medical personnel in use cannot according to the length of patient trauma's size adjustment blade.3, medical personnel are in the process of performing an operation, and as the time one is long, people is very easily tired, very easily slides when using scalpel.4, blade allows patient intuitively see, can from producing the possibility feared at heart.5, there is the possibility of maloperation, if maloperation enters locking position in operation, by the process of impact operation, incur loss through delay the therapeutic time of patient.
Utility model content
The purpose of this utility model be to provide a kind of can the disposable surgical cutter of self-locking, make its more compact structure, locked convenience, use safer.
The purpose of this utility model be achieved in that a kind of can the disposable surgical cutter of self-locking, comprise broach shell, be provided with sliding seat in described broach shell, sliding seat is provided with blade; Adopt the double wedge matched and tooth socket fit to be connected between described sliding seat and the interior upside of broach shell, described teeth groove is distributed with several along broach shell length direction, and sliding seat is connected with driving handle, and driving handle stretches out on the upside of broach shell; The tail end of sliding seat is provided with the elastic bayonet lock of upward opening, and broach shell upper back is provided with an opening, and described opening part is provided with elastic pressure bar, and the end of elastic pressure bar is provided with the clamping joint matched with described elastic bayonet lock; When sliding seat move rearwards to make clamping joint and elastic bayonet lock just pair time, press down elastic pressure bar and just can insert in elastic bayonet lock by push card joint.
When this utility model normally uses, sliding seat can slide anteroposterior, double wedge is connected with tooth socket fit, make the extension elongation of blade adjustable, during adjustment, promote double wedge by driving handle cross place teeth groove and be meshed with other corresponding teeth groove, one hand can adjust the length that blade stretches out at any time, and it is easy to operate.After having performed the operation, by pressing down driving handle pushing backward, sliding seat is moved backward, when sliding seat move rearwards to make clamping joint and elastic bayonet lock just pair time, pressing down elastic pressure bar just can in push card joint insertion elastic bayonet lock.Now, cannot blade be driven to stretch out by driving handle again, scalpel cannot reuse, and reaches disposable object, avoids cross infection.Compared with prior art, this utility model structure is simple, uses rear locked convenience, only for single use, uses safer.
Insert in elastic bayonet lock for ease of clamping joint, the wedge shape that described clamping joint is big up and small down.
As further improvement of the utility model, the opening both sides of elastic bayonet lock are corresponding to described clamping joint wedge shape, and the inner side of elastic bayonet lock is provided with the cavity holding clamping joint.This structure can ensure that clamping joint is easy to insert in elastic bayonet lock, meanwhile, can ensure that clamping is reliable, not easily deviate from.
Grip for convenience of operator, described broach shell outer surface is provided with anti-skidding raised line.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is the structural representation of sliding shoe.
Wherein, 1 broach shell, 2 sliding seats, 3 teeth groove, 4 driving handles, 5 double wedges, 6 openings, 7 clamping joints, 8 elastic pressure bars, 9 elastic bayonet locks, 10 anti-skidding raised lines, 11 blades.
Detailed description of the invention
As shown in Figure 1, for can the disposable surgical cutter of self-locking, comprise broach shell 1, be provided with sliding seat 2 in described broach shell 1, sliding seat 2 be provided with blade 11; Adopt the double wedge 5 that matches and teeth groove 3 to be connected between sliding seat 2 and the interior upside of broach shell 1, teeth groove 3 is distributed with several along broach shell 1 length direction, sliding seat 2 is connected with driving handle 4, and driving handle 4 stretches out on the upside of broach shell 1; The tail end of sliding seat 2 is provided with the elastic bayonet lock 9 of upward opening 6, and broach shell 1 upper back is provided with an opening 6, and opening 6 place is provided with elastic pressure bar 8, and the end of elastic pressure bar 8 is provided with the clamping joint 7 matched with described elastic bayonet lock 9; When sliding seat 2 move rearwards to make clamping joint 7 and elastic bayonet lock 9 just pair time, press down elastic pressure bar 8 and just can insert in elastic bayonet lock 9 by push card joint 7.The wedge shape that clamping joint 7 is big up and small down, opening 6 both sides of elastic bayonet lock 9 are corresponding to described clamping joint 7 wedge shape, and the inner side of elastic bayonet lock 9 is provided with the cavity holding clamping joint 7.Broach shell 1 outer surface is provided with anti-skidding raised line 10.
