Specific implementation mode

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

As shown in Figures 1 to 6, one kind is medical pulls out first device, including the upper clamp plate 1 and lower clamp plate 2 that radian is consistent, the upper folder 1 tail portion of plate is equipped with upper connecting rod 3, and 2 tail portion of the lower clamp plate is equipped with lower link 4, and 1 head of the upper clamp plate is equipped with perpendicular to upper clamp plate 1 arc to sawtooth mouth 11,2 head of the lower clamp plate is equipped with the edge of a knife 21, and the upper connecting rod 3 and lower link 4 are equipped with bullet by proximal end Property bindiny mechanism 5, the upper connecting rod 3 and lower link 4 are equipped at upper clamp plate 1 and lower clamp plate 2 can make upper clamp plate 1 and lower folder The tightening mechanism 6 that 2 head of plate is closed.The medical nail and nail for pulling out first device first by the edge of a knife 21 of lower clamp plate 2 to patient Lower part tissue is detached, and is then made the upper surface engagement of the grinding tooth mouth 11 and lower clamp plate 2 of upper clamp plate 1, is realized the smooth of nail It extracts, action process is smooth, avoids sufferer from bearing excessive pain, and improve the success rate of operation.Using 2 head of lower clamp plate When the edge of a knife 21 cuts nail and lower part tissue, do not tightened in tightening mechanism 6 between upper clamp plate 1 and lower clamp plate 2 In the case of keep state parallel to each other, and during carrying out nail extraction, by making tightening mechanism 6 become to tighten shape State realizes the intermeshing between upper clamp plate 1 and lower clamp plate 2, ensures the clamping between the two head, so as to nail applied force Amount carries out the extraction of nail, smooth coherent, the raising procedure efficiency of safety action.

As shown in Figures 1 to 6, as further optimization, flexible connection mechanism 5 includes upright bar 51, is set to upright bar 51 The end plate 52 at both ends and the first spring 53 for being set to the middle part of upright bar 51, the upright bar 51 pass through upper connecting rod 3 first through hole and Second through-hole of lower link 4 is arranged, and the end plate 52 is set to 4 outside of upper connecting rod 3 and lower link, and first spring 53 is arranged Between upper connecting rod 3 and lower link 4.Flexible connection mechanism 5 is set between upper clamp plate 1 and lower clamp plate 2, and realization therebetween may be used To be in the effect of required position under the collective effect of end plate 52 and the first spring 53, upright bar 51 passes through upper connecting rod 3 and lower company Bar 4, end, by 51 both ends of upright bar be arranged end plate 52 position of upper connecting rod 3 and lower link 4 is defined, set simultaneously The first spring 53 between upper connecting rod 3 and lower link 4 is placed in convenient for cooperation 6 later stage of tightening mechanism to upper clamp plate 1 and lower clamp plate 2 Realize engagement second, mechanism is simply smooth, easy to operation.

As shown in Figures 1 to 5, as further optimization, tightening mechanism 6 includes bolt 61, is set to 61 tail portion of bolt Wing nut 62 and be set to the second spring 63 at the middle part of bolt 61, the bolt 61 pass through upper connecting rod 3 third through-hole and The fourth hole of lower link 4 is arranged, and the head of the bolt 61 and wing nut 62 are located at upper connecting rod 3 and lower link 4 Outside.By tightening the wing nut 62 of 61 tail portion of bolt, 61 middle part of compression bolt is sheathed on second on 61 body of rod of bolt Spring 63 realizes that the sawtooth mouth 11 on 1 head of upper clamp plate is moved to 2 direction of lower clamp plate, realizes sawtooth mouth 11 and 2 upper surface of lower clamp plate Engagement reduce the difficulty pulled out convenient for pulling out required power to nail application, improve procedure efficiency.

As shown in Figures 1 to 4, as further optimization, the edge of a knife 21 is curved edge, and radian and 2 radian of lower clamp plate Unanimously.The knife edge side of the edge of a knife 21 is extending axially outward along lower clamp plate 2, and the radian of the edge of a knife 21 is consistent with the radian of lower clamp plate 2, For the smooth extension outward of lower clamp plate 2,21 stressed effect of the edge of a knife is good, convenient for doctor operate, can be smoothed out nail with The lock out operation of lower-hierarchy.

As shown in Figure 1 to Figure 3, as further optimization, 1 size of upper clamp plate is less than 2 size of lower clamp plate.Due to referring to After first and lower-hierarchy are detached, needs that further nail is carried out to pull out operation, under the action of tightening mechanism 6, need The sawtooth mouth 11 of upper clamp plate 1 can smoothly realize the engagement between 2 upper surface of lower clamp plate, and be designed as 1 size of upper clamp plate Less than the size of lower clamp plate 2, then upper clamp plate 1 can be contacted smoothly with lower clamp plate 2 during pushing, be ensured between the two good Good engagement, convenient for realizing clamping action to nail, further to apply the dynamics pulled out.

As shown in Figures 1 to 5, as further optimization, the angle of two bevel edges of sawtooth mouth 11 is α, and α is 45 ° -60 °. The direction that the setting of sawtooth mouth 11, the engagement being easy to implement between upper clamp plate 1 and lower clamp plate 2, and sawtooth mouth 11 are arranged and upper folder The arc of plate 1 is perpendicular, can preferably realize clamping action, avoids the generation of the slipping phenomenon during pulling out.Sawtooth mouth The angle being arranged between 11 two bevel edges has a tremendous influence to the force stability of sawtooth mouth 11, and 45 ° -60 ° of angle, both Ensure that stressed effect is good, while also allowing for producing and processing, can effectively reduce cost of manufacture.

As shown in Figures 1 to 5, further include 3 top of upper connecting rod position corresponding with 4 lower section of lower link as further optimization The Antiskid handle 41 at place is set, the Antiskid handle 41 is set between tightening mechanism 6 and elastic machine bindiny mechanism 5.Antiskid handle 41 setting stablizes force in operation convenient for doctor, avoids the appearance due to slipping phenomenon such as hand perspirations, ensures to suffer from Within the shortest time, most fast completion surgical procedure improves work efficiency, while also greatly reducing the pain of patient person Hardship has good using effect.

The utility model is simple in structure, easy to use, realizes cutting separation respectively by lower clamp plate and upper clamp plate and refers to The function that first is pulled out, doctor can pull out first device by this and disposably be embedded under the nail of patient and pull out, and nail removal is thorough Bottom avoids jaw from being embedded in pain caused by under first twice, improves the efficiency of operation, ensure that the removal effect of bad nail, carry The high success rate of diagnosis and treatment, has universal applicability.

The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality All any modification, equivalent and improvement etc., should be included in the guarantor of the utility model made by within novel spirit and principle Within the scope of shield.
