Description

A kind of detachable clamp

(1) technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of detachable clamp.

(2) background technology

Often need use clamp in the medical operating, but existing clamp is generally integrated design, be that binding clip, scalable push rod, claw beam, pincers handle are non-disconnectable connection, bulky, be inconvenient to dismantle, like this will be very inconvenient when cleaning clamp, may cause sterilization thorough inadequately during cleaning, thereby often just can only use as disposable product.

(3) utility model content

Technical problem to be solved in the utility model is to provide a kind of clamp simple in structure, for convenience detach.

Described detachable clamp comprises vice body, pincers handle, and described vice body comprises binding clip, scalable push rod, claw beam, and described binding clip is fixedlyed connected with scalable push rod, and scalable pushing rod sleeve is connected in the claw beam and from the claw beam end and stretches out; Described pincers negative winding stem is equipped with the claw beam seat and cooperates with vice body, described pincers handle tail is the handle of being made up of pull end, back handle, the rotating disk that also can slide relatively on described claw beam seat comprises sleeve and is socketed in sleeve, described sleeve and pincers negative winding stem axial restraint are provided with back-moving spring between described rotating disk inwall and the sleeve outer wall; Described barrel forward end is along being circumferentially with the hole that ball is installed, and the end of described claw beam is provided with the groove that cooperates with ball, has the recess that holds described ball after rotating disk is with respect to sleeve when moving on the described rotating disk inwall.

In order to prevent that the pull end displacement is excessive when gripping the pincers handle, also need usually to install additional and prevent the over-drastic device of pull end displacement.Further, described pull end inboard is provided with first spring leaf, and handle inboard, described back is provided with second spring leaf, and first spring leaf withstands second spring leaf.When holding pull end, two spring leafs form certain force of strain, are not easy to make the pull end displacement excessive like this.

Further, handle inboard, described back is provided with and prevents the over-drastic push rod of pull end displacement.Arrive to a certain degree when gripping pull end, push rod just can withstand the inboard of pull end.

Further, have breach on the excircle of described claw beam end, the excircle of rotating disk front end is provided with the axial projection that cooperates with above-mentioned breach.Above-mentioned design can so just can be adjusted the angle of clamp work by the rotation of rotating disk so that rotating disk and claw beam are made circumference synchronously to rotate.

Detachable titanium clamp pincers of the present utility model is simple in structure, only needs the tractive rotating disk just vice body and pincers shank portion can be mounted and dismounted easily after finishing using, and makes the cleaning of clamp and sterilization more thorough.

(4) description of drawings

Fig. 1 is the structural representation of embodiment 1 described detachable clamp.

Fig. 2 is the structural representation of embodiment 2 described detachable clamps.

(5) specific embodiment

The utility model is described in further detail below in conjunction with embodiment, but protection domain of the present utility model is not limited to this.

Embodiment 1

With reference to Fig. 1, a kind of detachable clamp comprises vice body, pincers handle, and described vice body comprises binding clip 1, scalable push rod 2, claw beam 3, and described binding clip 1 is fixedlyed connected with scalable push rod 2, and scalable push rod 2 is socketed in the claw beam 3 and from claw beam 3 ends and stretches out; Described pincers negative winding stem is equipped with the claw beam seat and cooperates with vice body, described pincers handle tail is the handle of being made up of pull end 4, back handle 5, the rotating disk 7 that also can slide relatively on described claw beam seat comprises sleeve 6 and is socketed in sleeve 6, described sleeve 6 and pincers negative winding stem axial restraint are provided with back-moving spring 8 between described rotating disk 7 inwalls and sleeve 6 outer walls; Described sleeve 6 front end edges are circumferentially with the hole that ball 9 is installed, and the end of described claw beam is provided with the groove that cooperates with ball, has the recess 10 that holds described ball 9 after rotating disk 7 is with respect to sleeve 6 when moving on described rotating disk 7 inwalls.

Described pull end 4 inboards are provided with first spring leaf 11, and handle inboard, described back is provided with second spring leaf, 12, the first spring leafs 11 and withstands second spring leaf 12.

Have breach on the excircle of described claw beam 3 ends, the excircle of rotating disk 7 front ends is provided with the axial projection 13 that cooperates with above-mentioned breach.

This utility model when mounted, the tractive rotating disk 7 backward, ball 9 falls into recess 10, and scalable push rod 2 is inserted in the sleeves 6; Loosen rotating disk 7 again, under back-moving spring 8 effects, rotating disk 7 is pressed into ball 9 in the groove 10, and projection 13 inserts in the breach of claw beam 3 simultaneously, has so just finished the assembling of clamp.During use, turn rotating disk 7 just can drive claw beam 3, binding clip 1 rotates, thereby can make binding clip 1 be in the optimal operations angle.

During dismounting, the tractive rotating disk 7 backward, and scalable push rod 2 is got final product by extracting out in the sleeve 6.

The scalable push rod of present embodiment realizes that by being provided with stage clip 14 at

claw beam

3 and 2 of push rods stage clip 14 is in the end of claw beam.When holding down pull end, push rod is pushed forward, and binding clip clamps; Loosen pull end, under stage clip 14 effects, the push rod return.Certainly those skilled in the art can also adopt other known method to make push rod get final product with respect to claw beam is scalable.

Embodiment 2

The difference part of present embodiment and embodiment 1 is that handle 5 inboards, described back are provided with and prevents the over-drastic push rod 15 of pull end 4 displacements.Arrive to a certain degree when gripping pull end, push rod 15 just can withstand the inboard of pull end 4.
