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 is to provide a kind of locking mechanism of disposable safe scalpel, makes its more compact structure, locked convenience, use safety, easy to operate.
The purpose of this utility model is achieved in that a kind of locking mechanism of disposable safe scalpel, comprises broach shell, is provided with for installing blade and can the sliding seat of slide anteroposterior in described broach shell; Adopt the double wedge matched and tooth socket fit to be connected between 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, stretches out the elongated slot of driving handle on the upside of broach shell; The tail end of sliding seat is provided with stopper slot, and on broach shell, correspondence is provided with gag lever post, and gag lever post both sides are provided with fixture block, is provided with two pieces of clamping blocks in broach shell, and gag lever post is clamped between two pieces of clamping blocks, and fixture block is positioned on the upside of clamping block; When sliding seat move rearwards to make stopper slot just to gag lever post end time, push gag lever post downwards and make fixture block move to below clamping block, gag lever post inserts in described stopper slot just.
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 and pushing backward, when sliding seat move rearwards to make stopper slot just to gag lever post end time, pushing gag lever post downwards makes fixture block move to below clamping block, and gag lever post inserts in described stopper slot just, 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.
Move to below clamping block for being convenient to fixture block further, and ensure that it can not return above clamping block, described fixture block both sides are wedge shape.
For ease of fixture block motion, described gag lever post lower ending opening, upper end link together, and take the shape of the letter U.The aperture position deformable of gag lever post, when fixture block moves to after below clamping block, it can elastic recovery, and fixture block can be snapped into below clamping block.
For ensureing that fixture block moves downward smoothly further, can not again get back to above clamping block, curved with the contact position of fixture block inside described clamping block upper end, clamping block lower end be that acute angle is arranged simultaneously.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation of blade when stretching out.
This utility model structural representation when Fig. 2 is locking state.
Fig. 3 is the partial enlarged drawing of A in Fig. 1.
Wherein, 1 blade, 2 teeth groove, 3 sliding seats, 4 driving handles, 5 double wedges, 6 gag lever posts, 7 fixture blocks, 8 clamping blocks, 9 broach shells.
Detailed description of the invention
As Figure 1-3, being the locking mechanism of disposable safe scalpel, comprising broach shell 9, being provided with for installing blade 1 and can the sliding seat 3 of slide anteroposterior in broach shell 9; Adopt the double wedge 5 that matches and teeth groove 2 to be connected between sliding seat 3 and the interior upside of broach shell 9, teeth groove 2 is distributed with several along broach shell 9 length direction, sliding seat 3 is connected with driving handle 4, stretches out the elongated slot of driving handle 4 on the upside of broach shell 9; The tail end of sliding seat 3 is provided with stopper slot, and on broach shell 9, correspondence is provided with gag lever post 6, and gag lever post 6 both sides are provided with fixture block 7, is provided with two pieces of clamping blocks 8 in broach shell 9, and gag lever post 6 is clamped between two pieces of clamping blocks 8, and fixture block 7 is positioned on the upside of clamping block 8; Fixture block 7 both sides are wedge shape, and state gag lever post 6 lower ending opening, upper end links together, take the shape of the letter U, it has certain elasticity; Curved with the contact position of fixture block 7 inside clamping block 8 upper end, clamping block 8 lower end is that acute angle is arranged; When sliding seat 3 move rearwards to make stopper slot just to gag lever post 6 end time, push gag lever post 6 downwards and make fixture block 7 move to below clamping block 8, gag lever post 6 just inserts in described stopper slot.
During normal use, sliding seat 3 can slide anteroposterior, double wedge 5 and teeth groove 2 are connected, make the extension elongation of blade 1 adjustable, during adjustment, promote double wedge 5 by driving handle 4 cross place teeth groove 2 and be meshed with other corresponding teeth groove, one hand can adjust the length that blade 1 stretches out at any time, and it is easy to operate.After having performed the operation, by pressing down driving handle 4 and pushing backward, when sliding seat 3 move rearwards to make stopper slot just to gag lever post 6 end time, pushing gag lever post 6 downwards makes fixture block 7 move to below clamping block 8, and gag lever post 6 inserts in described stopper slot just, now, cannot blade 1 be driven to stretch out by driving handle 4 again, scalpel cannot reuse, and reaches disposable object, avoids cross infection.
This utility model is not limited to above-described embodiment; on the basis of technical scheme disclosed in this utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some technical characteristics wherein to replace and distortion, these are replaced and are out of shape all in protection domain of the present utility model.
