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 dead lock for safety mechanism for scalpel, makes it reliably locked, use safety, easy to operate.
The purpose of this utility model is achieved in that a kind of dead lock for safety mechanism for scalpel, comprises broach shell, is provided with for installing blade and can the sliding seat of slide anteroposterior in described broach shell; It is characterized in that: 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, and driving handle stretches out on the upside of broach shell; The tail end of sliding seat is provided with two pieces of flexure strips, two pieces of flexure strips be arranged in parallel and leave gap, the forward surface of two pieces of flexure strips is fixed with respectively the fixture block of right angled triangle, a right-angle side of described right angled triangle is fixed on corresponding flexure strip, another right-angle side is on front side of broach shell, be positioned at fixture block rear in broach shell and be provided with clamping block, described fixture block is corresponding with clamping block; When sliding seat moves backward, clamping block can insert between two pieces of fixture blocks just, and fixture block is stuck on rear side of clamping block.
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 moves backward, clamping block drives flexure strip elastic deformation, clamping block can be inserted between two pieces of fixture blocks just, and fixture block is stuck on rear side of clamping block.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.
For ensureing that locking is reliable, described clamping block is that isosceles triangle is arranged, and the vertex correspondence of isosceles triangle is between fixture block.
For being convenient to clamping block relative motion further, reach locked object, described clamping block front end is provided with the guide part extended on front side of broach shell.Guide part play the guiding role, and it can insert between fixture block in advance, so that fixture block is stuck on rear side of clamping block further.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Wherein, 1 broach shell, 2 sliding seats, 3 teeth groove, 4 driving handles, 5 double wedges, 6 flexure strips, 7 fixture blocks, 8 clamping blocks, 8a guide part, 9 blades.
Detailed description of the invention
As shown in Figure 1, comprising broach shell 1 for a kind of for the dead lock for safety mechanism of scalpel, being provided with for installing blade 9 and can the sliding seat 2 of slide anteroposterior in described broach shell 1; 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 two pieces of flexure strips 6, two pieces of flexure strips 6 be arranged in parallel and leave gap, the forward surface of two pieces of flexure strips 6 is fixed with respectively the fixture block 7 of right angled triangle, a right-angle side of described right angled triangle is fixed on corresponding flexure strip 6, another right-angle side is on front side of broach shell 1, be positioned at fixture block 7 rear in broach shell 1 and be provided with clamping block 8, described fixture block 7 is corresponding with clamping block 8; Clamping block 8 is arranged in isosceles triangle, and the vertex correspondence of isosceles triangle is between fixture block 7, and clamping block 8 front end is provided with the guide part 8a extended on front side of broach shell 1; When sliding seat 2 moves backward, clamping block 8 can insert between two pieces of fixture blocks 7 just, and fixture block 7 is stuck on rear side of clamping block 8.
During use, sliding seat 2 can slide anteroposterior, double wedge 5 and teeth groove 3 are connected, make the extension elongation of blade 9 adjustable, during adjustment, promote double wedge 5 by driving handle 4 cross place teeth groove 3 and be meshed with other corresponding teeth groove, one hand can adjust the length that blade 9 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 2 moves backward, clamping block 8 drives flexure strip 6 elastic deformation, clamping block 8 can be inserted between two pieces of fixture blocks 7 just, and fixture block 7 is stuck on rear side of clamping block 8.Now, cannot blade 9 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.
