Specific embodiment

As Figure 1-Figure 5, in order to improve disposable surgical knife in the preoperative with postoperative safety coefficient, disposably stretch hand Art knife, the sliding part 200 including knife handle 100 and for doing stretching motion relative to knife handle 100 with cutting blade, knife handle 100 have Sliding slot 110, sliding part 200 are slided relative to the sliding slot 110 of knife handle 100, have the first lock between sliding part 200 and sliding slot 110 Determine state, the second lock state and locking state, the first lock state and the second lock state of sliding part 200 and sliding slot 110 By the sliding of sliding part 200 realization mutually switching, 200 second lock state of sliding part passes through 200 slide handover of sliding part to lock Death situation state, sliding part 200 are push button, push push button to slide relative to knife handle 100 by manpower, the first lock state refers to hand The state of art knife when in use ensures scalpel blade when in use by the way that sliding part 200 is slid into the first lock state It oneself will not shrink back, need to push push button that could retract blade in knife handle 100 by manpower, the second lock state refers to The state that scalpel does not use in the preoperative, the blade under the second lock state in knife handle 100, can not voluntarily stretch out knife handle always 100, blade will not be made to stretch out knife handle 100 because of certain casual operations, it can be just to make that push button can only be pushed to by manpower Blade stretches out knife handle 100, avoids the problem that blade scratches medical staff, improves the safe operation of scalpel in the preoperative Property, locking state refer to scalpel after use, and blade locks the state in knife handle 100, under the state, blade without Method stretches out knife handle 100 again, guarantees that the blade for also remaining blood by operation can not scratch medical staff and infection etc. is caused to ask Topic occurs.

It is flexible in knife handle 100 in order to enable the blade to, including blade holder 300, knife handle 100 is interior to be had for blade holder 300 The chamber of sliding, sliding slot 110 are connected with chamber, and sliding part 200 is assembled through sliding slot 110 and blade holder 300, and blade is mounted on In blade holder 300, realize that the flexible and state of blade switches by blade holder 300 and being linked for sliding part 200.

In order to realize that the first lock state and the second lock state of blade, 110 cell wall of sliding slot are equipped with the first retention bead 111 and second retention bead 112, sliding part 200 there is retention bead 210, the first locking shape of sliding part 200 and sliding slot 110 State is cooperated by the retention bead 210 of sliding part 200 and the first retention bead 111 of 110 cell wall of sliding slot to be realized, sliding part 200 Pass through the retention bead 210 of sliding part 200 and the second retention bead of 110 cell wall of sliding slot with the second lock state of sliding slot 110 112 cooperations are realized, realize hand by the cooperation of retention bead 210 of the first retention bead 111 and sliding part 200 on knife handle 100 State when art knife uses locks, and is matched by the retention bead 210 of the second retention bead 112 and sliding part 200 on knife handle 100 It closes and realizes the state locking of scalpel when not used.

In order to realize that the locking state of blade, knife handle 100 are located at 110 two sides of sliding slot or in which side and are equipped with guide groove 120, Knife handle 100 is additionally provided with lock slots 130, and sliding part 200 is equipped with clamping block 220, an end slot of the guide groove 120 close to lock slots 130 Wall is inclined-plane, and the side side wall of clamping block 220 and 120 respective direction of guide groove is inclined-plane, and sliding part 200 passes through clamping block 220 From guide groove 120 slide into lock slots 130 realize locking state, scalpel after use, by push push button make sliding part 200 clamping block 220 slides into lock slots 130 from guide groove 120, since guide groove 120 is set close to one end of lock slots 130 There is inclined-plane, while also being provided with inclined-plane on clamping block 220, so clamping block 220 can be from guide groove in the case where external force pushes It is slid into 120 in lock slots 130, after clamping block 220 enters lock slots 130, sliding part 200 will be unable to push, thus real Now locked purpose.

In order to enable the blade to normally switch lock state, the first retention bead 111, the second retention bead 112 and limit Position protrusion 210 is arc convex, and if protrusion is rectangular, state switching will become very laborious, needs very big power Gas can just switch to lock state, or even can not switch, so using arc convex, convenient for the contact between retention bead 210 Cooperation.

In order to keep the locking effect of blade more preferable, the two sides cell wall of sliding slot 110 is correspondingly provided with 111 He of the first retention bead Second retention bead 112, accordingly, 200 two sides of sliding part are equipped with corresponding retention bead 210, are reached by being arranged two groups Better locking effect.

In order to enable sliding part 200 to enter locking shape from by the first retention bead 111 and the second retention bead 112 State, the two sides that sliding part 200 is contacted with the first retention bead 111 and the second retention bead 112 are equipped with arc bump 240, lead to Crossing arc bump 240 and the first retention bead 111 and the cooperation of the second retention bead 112 enables sliding part 200 from sliding mode Into lock state.

In order to which blade holder 300 and sliding part 200 are assembled together, blade holder 300 has inserts for what sliding part 200 was inserted into Hole 310, the two sidewalls of jack 310 are equipped with card slot, and 200 two sidewalls of sliding part are equipped with fixture block 230, and sliding part 200 is inserted into blade holder It is engaged by clamping in 300 jack 310 and by fixture block 230 and the card slot of blade holder 300 and is fixed, assembled by clamping structure Linkage, but it's not limited to that for its connection structure, can be connected by other connection types.

In order to realize the multifunction of scalpel, 100 surface of knife handle is equipped with size scale 140, can play one Fixed measurement effect.

The knife handle 100 is equipped with limit sliding chutes 150, and sliding slot 110, guide groove 120 and lock slots 130 are placed in limit and slide In slot 150, the upper surface of sliding part 200 protrudes from limit sliding chutes 150, is convenient for finger push sliding part 200.
