Abstract

The invention discloses vertebra restoration pincers held with one hand. The vertebra restoration pincers comprise a pincer handle held with one hand, wherein the pincer handle is composed of a first handle and a second handle which are connected in a pivoting mode, a pincer rod is connected to the end of the first handle in a pivoting mode, a pincer sliding block is arranged at the end of the pincer rod, a sleeve is arranged at the end of the second handle, and a rabbet vertebra pincer body is arranged at the end of the sleeve; the sleeve is connected to the pincer rod in a sliding mode, the pincer sliding block is connected to the rabbet vertebra pincer body in a sliding and sleeved mode, the first handle and the second handle rotate in a pivoting mode, and the rabbet vertebra pincer body is driven to be open and closed within the sliding stroke of the pincer sliding block. According to the vertebra restoration pincers, medical staff can operate the pincers with a single hand, operation is convenient and fast, and holding strength is low; due to the additional arrangement of a locking mechanism, a pincer head does not get loose easily after clamping and positioning are conducted, medical staff do not need to apply clamping force all the time, and the labor intensity of medical staff is relieved.

Description

A kind of vertebrae reduction forceps of single hand type
Technical field
The present invention relates to a kind of vertebrae reduction forceps, relate in particular to a kind of vertebrae reduction forceps of single hand type, belong to field of medical device technology.
Background technology
Vertebrae resets need to use vertebrae reduction forceps, and medical worker carries out vertebrae reset rectification by vertebrae reduction forceps and waits operative treatment.
In prior art, vertebrae reduction forceps simple structure, need to carry out bimanualness, very not convenient, stability is lower, and labor intensity is high, and in operating process, need medical worker's specialized operations vertebrae reduction forceps, this medical worker cannot carry out other medical treatment action.
Summary of the invention
The object of the invention is to solve above-mentioned technical problem, propose a kind of vertebrae reduction forceps of single hand type.
Object of the present invention, to be achieved by the following technical programs: a kind of vertebrae reduction forceps of single hand type, especially, described vertebrae reduction forceps comprises the clamp handle being hold by one hand, first handle and second handle that described clamp handle is connected by pivot form, described first handle end pivot is connected with clamp bar, and the end of described clamp bar is provided with clamp slide block; The end of described second handle is provided with sleeve pipe, and the end of described sleeve pipe is provided with notch vertebra clamp; Described sleeve pipe is slidably connected to described clamp bar, and described clamp slide block is slidably socketed in described notch vertebra clamp, and described first handle and second handle pivot rotate, and in described clamp slide block sliding stroke, described notch vertebra clamp is driven and opens or closure.
Further, described clamp handle is provided with locking mechanism.
Further, described locking mechanism is made up of group card lock part and the positioning tooth wheel plate that match, described positioning tooth wheel plate is provided with plural tooth rank, the described group of card lock part and positioning tooth wheel plate are arranged at respectively first handle and the second handle of described clamp handle, and described positioning tooth wheel plate is with the described group of mutual clamping of card lock part or separate.
Further, between described first handle and second handle, be provided with back-moving spring.
Further, described second handle is provided with and is suitable for the spacing block set that palm thumb web supports.
Beneficial effect of the present invention is mainly reflected in: the proposition of innovation a kind of vertebrae reduction forceps of single hand type, medical worker only needs one-handed performance, convenient and swift, and grip intensity low; Set up locking mechanism, behind gripping location, binding clip can not get loose, and applies the strength of gripping without medical worker always, has alleviated medical worker's labor intensity.
Brief description of the drawings
Fig. 1 is the structural representation of the vertebrae reduction forceps of a kind of single hand type of the present invention.
Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, so that technical solution of the present invention is easier to understand, grasp.A kind of vertebrae reduction forceps of single hand type, it is characterized in that: described vertebrae reduction forceps comprises the clamp handle being hold by one hand, first handle and second handle that described clamp handle is connected by pivot form, described first handle end pivot is connected with clamp bar, and the end of described clamp bar is provided with clamp slide block; The end of described second handle is provided with sleeve pipe, and the end of described sleeve pipe is provided with notch vertebra clamp; Described sleeve pipe is slidably connected to described clamp bar, and described clamp slide block is slidably socketed in described notch vertebra clamp, and described first handle and second handle pivot rotate, and in described clamp slide block sliding stroke, described notch vertebra clamp is driven and opens or closure.
As shown in Figure 1, a kind of vertebrae reduction forceps of single hand type, especially, vertebrae reduction forceps comprises the clamp handle being hold by one hand, first handle 1 and second handle 2 that clamp handle is connected by pivot form, and first handle 1 end pivot is connected with clamp bar 3, and the end of clamp bar 3 is provided with clamp slide block 4; The end of second handle 2 is provided with sleeve pipe 5, and the end of sleeve pipe 5 is provided with notch vertebra clamp 6; Sleeve pipe 5 is slidably connected to clamp bar 3, clamp slide block 4 is slidably socketed in notch vertebra clamp 6, first handle 1 rotates with second handle 2 pivots, sleeve pipe 5 slides on clamp bar 3, clamp slide block 4 slides on notch vertebra clamp 6, is driven and opens or closure at clamp slide block 4 sliding stroke inner tank mouths vertebra clamps 6.
Wherein, clamp handle is provided with locking mechanism 7, and locking mechanism is for locking or the clamp handle that gets loose.Concrete, locking mechanism 7 is made up of group card lock part 71 and the positioning tooth wheel plate 72 that match, positioning tooth wheel plate 72 is provided with plural tooth rank, positioning tooth wheel plate has multiple clampings position by plural gear and group card lock part, dial first handle 1 and second handle 2 that card lock part 71 and positioning tooth wheel plate 72 are arranged at respectively clamp handle, positioning tooth wheel plate 72 with dial the mutual clamping of card lock part 71 or separate.
In addition, between first handle 1 and second handle 2, be provided with back-moving spring 8, stir under state at group card lock part, back-moving spring separates positioning tooth wheel plate with group card lock part.
Finally, second handle 2 is provided with and is suitable for the palm spacing block set 9 that palm thumb web supports, and palm spacing block set can prevent from gripping and get loose.
When concrete enforcement, when clamping vertebrae reduction forceps, medical worker grips clamp handle, first handle and second handle are in open configuration, the jaw of notch vertebra clamp is positioned to vertebrae both sides, grip and clamp first handle and second handle, second handle holding position is constant, first handle clamps towards second handle, clamp bar slides under first handle driving condition in sleeve pipe, clamp slide block slides and makes notch vertebra clamp clamping vertebrae on notch vertebra clamp, simultaneously, positioning tooth wheel plate is plugged in to be dialled in card lock part, and with the motion of first handle teeth change rank, until vertebrae is complete by the clamping of vertebra clamp, while separating vertebrae reduction forceps, stir card lock part, under the effect of back-moving spring, positioning tooth wheel plate is separated with dialling card lock part, and first handle and second handle open, and now clamp slide block slides notch vertebra clamp is opened, and vertebrae gets loose.
