Detailed description of the invention

Below in conjunction with concrete accompanying drawing, the utility model is described in further detail。

As shown in Figures 1 and 2, including the porous traction belt 1 for hook tractive notching edge, for hook porous traction belt 1 and regulate the arc regulating arm 2 of tractive height and angle, the cross bar fixed arm 3 for fixing with operation table edge rail and arc regulating arm 2 temporarily。Described porous traction belt 1 is set to one end and connects the soft ribbons of arc-shaped draw hook blade 11 or fixation clamp 12, and soft ribbons arranges some hook holes 10 along major axis。Described arc regulating arm 2 epimere is provided for hook the arc upper arm 21 of tractive porous traction belt 1, and hypomere is set to the linear type regulating arm 22 being connected as a single entity with arc upper arm 21。Described cross bar fixed arm 3 is provided with the adjustment engagement arm 5 for the cross bar fixed mechanism 4 fixed with operation table edge rail temporarily for hypomere。Described linear type regulating arm 22 and regulate the engagement arm 5 adjustment fixed mechanism 60 that can be adjusted the height of arc upper arm 21 and angle and pass through being arranged in linear type regulating arm 22 or adjustment engagement arm 5 of working in coordination and fix temporarily。

The universal fixing drag hook of described height adjustable by cross bar fixed arm 3 by the cross bar fixed mechanism 4 of bottom can be safe be fixed in operation table edge rail, provide enough support forces for other assembly。The adjustment engagement arm 5 on cross bar fixed arm 3 top and linear type regulating arm 22 can be worked in coordination assembling, thus to the angle of linear type regulating arm 22 assembling be highly adjusted, fix again through adjustment fixed mechanism 60 after having adjusted temporarily。Now the support arm of force of the universal fixing drag hook of height adjustable completes。The arc-shaped draw hook blade 11 of the state of use or fixation clamp 12 need to be hooked in the arc upper arm 21 of arc regulating arm 2 epimere by the hook hole 10 of appropriate location in porous traction belt 1 soft ribbons and can complete operation start operation by follow-up。

In said modules, the material that the preferred soft tough and tensile elasticity of soft ribbons part of porous traction belt 1 is poor makes, so can provide enough support force for the arc-shaped draw hook blade 11 of front end or fixation clamp 12, be avoided that again the arc-shaped draw hook blade 11 of elastic excessive front end or fixation clamp 12 accidentally injure evil medical personnel when shirking under elastic acting force。Other assembly materials require that quality hard elastomeric is little, it is preferable that the plastics etc. of metal material or quality metalloid。

Described arc regulating arm 2 hypomere is set to linear type regulating arm 22, can by linear type regulating arm 22 with regulate engagement arm 5 and coordinate and carry out the angle orientation that the arc upper arm 21 rotating to be epimere of different angles provides different, coordinate the arc upper arm 21 to epimere to provide desirable height by the height of linear type regulating arm 22 with adjustment engagement arm 5。After height and angle complete, angle that linear type regulating arm 22 is regulated by self arc length bar by arc upper arm 21 and highly extend to wound and need the optimum position of tractive, best stress point is provided for porous traction belt 1, decrease the space requirement to operation bedside edge as far as possible, decrease the interference to surgical doctor of the height adjustable universal fixing drag hook。

As it is shown on figure 3, the paired jig arm 13 that described fixation clamp 12 is made for quality stiff materials, the sheathed dead ring 14 of jig arm 13 back segment, dead ring 14 can make the pair of jig arm 13 jaws when sliding to jig arm 13 leading portion and tighten up。When being embodied as, the material of paired jig arm 13 has the elasticity of self, 13 liang of jig arm of jig arm are opened in pairs before use, form V-shaped state, dead ring 14 is positioned at the tail end of the paired jig arm 13 of V-shaped state, when needs folder closes paired jig arm 13, dead ring 14 is moved to V-shaped state paired jig arm 13 opening。

As shown in Figure 1, Figure 2 and shown in Fig. 4, it is shaft-like that the arc upper arm 21 of described arc regulating arm 2 epimere includes class arc, and top, top is provided with the hook 23 of hanging hole 10 of rising to the bait for hook porous traction belt 1。

When being embodied as, the trunk side that arc upper arm 21 position of described arc regulating arm 2 epimere lies low patient extends to the middle part of trunk or amesiality, no matter need the position of tractive wherein, the curved bend curvature of described arc upper arm 21 should be similar with the radian on patient's trunk side, can reach to reduce the purpose taking operation surrounding space。

Shown top, arc upper arm 21 top arranges hook 23 can be linked into porous traction belt 1 soft ribbons along the hook hole 10 that major axis is arranged。Slipping to reduce porous traction belt 1, described hook 23 is preferably arranged to the mushroom profile that thick bottom, top is thinner。Needing prompting, the embodiment of described hook 23 has many, and mushroom hook 23 herein is a kind of simple embodiment simply。

As shown in Figures 1 and 2, described linear type regulating arm 22 and adjustment engagement arm 5 include the sleeve mechanism 6 that can the height of arc upper arm 21 and angle be adjusted of working in coordination。In described linear type regulating arm 22 and adjustment engagement arm 5, one is interpolation pole 61, and another is outer sleeve 62。External diameter and the outer sleeve 62 barrel chamber internal diameter of described interpolation pole 61 match, and interpolation pole 61 can be embedded in outer sleeve 62 into the barrel chamber and move along major axis。Described adjustment fixed mechanism 60 is arranged on the socket of outer sleeve 62 barrel chamber。

In embodiment shown in detail in this figure, linear type regulating arm 22 is set to interpolation pole 61, and regulates engagement arm 5 and be set to outer sleeve 62。By linear type and match each other interpolation pole 61 anglec of rotation in outer sleeve 62 position of the arc upper arm 21 of arc regulating arm 2 epimere can be carried out suitable adjustment。The placed-depth in outer sleeve 62 by linear type the interpolation pole 61 that matches each other, suitably can adjust the height of the arc upper arm 21 of arc regulating arm 2 epimere。After adjustment completes, fix by regulating fixed mechanism 60 temporarily。Described adjustment fixed mechanism 60 is arranged on how many interpolation poles 61 when the advantage of the socket of outer sleeve 62 barrel chamber is no matter to be embodied as inserts the length in outer sleeve 62, all can be effectively fixing。

As shown in Figures 5 and 6, the cross section of described interpolation pole 61 and outer sleeve 62 barrel chamber cross section are the circle that the edge mated is uniformly arranged teeth, and size and all adjacent teeth spacing of all teeth are all consistent。

Fig. 5 is the cross section of interpolation pole 61, and Fig. 6 is outer sleeve 62 cross section。It should be noted that coupling herein refers to the teeth of the cross section of interpolation pole 61 and the teeth recessed fit in outer sleeve 62 barrel chamber cross section, the teeth depression of the cross section of interpolation pole 61 is mated with the teeth in outer sleeve 62 barrel chamber cross section。Meanwhile, the teeth of the cross section of interpolation pole 61 are smaller compared with the teeth in outer sleeve 62 barrel chamber cross section depression, and the teeth depression of the cross section of interpolation pole 61 is bigger compared with the teeth in outer sleeve 62 barrel chamber cross section。So, interpolation pole 61 can insert outer sleeve 62 into the barrel chamber along different angles, and after interpolation pole 61 inserts outer sleeve 62 into the barrel chamber, can not rotate under the obstruction of teeth, it is nested with, after increasing interpolation pole 61 angle adjustment further, the stability being inserted in outer sleeve 62, provides stable angle traction force for porous traction belt 1。

Need further exist for reminding be teeth length and the impact of angular adjustment is by density: the density of teeth is more many, angle between adjacent teeth is more little, when carrying out angular adjustment between interpolation pole 61 and outer sleeve 62, the minimum angles of adjustment is more little, and during adjusting angle, degree of regulation is more high；But the density of teeth is more many, the depression between teeth is more little, and teeth length more little (now teeth are too carefully easy for dialysis), the insert depth that described interpolation pole 61 and outer sleeve 62 are relatively fixed formula is more little, and degree of stability can decline to some extent。On the contrary, teeth are more big, and the angle between adjacent teeth is more big, and when carrying out angular adjustment between interpolation pole 61 and outer sleeve 62, the minimum angles of adjustment is more big, and during adjusting angle, degree of regulation is more rough；But the insert depth that described interpolation pole 61 and outer sleeve 62 are relatively fixed formula is more big, and degree of stability can increase。When being embodied as, need to according to the thickness of actual interpolation pole 61 and outer sleeve 62 and operation time tractive dynamics teeth number the most appropriate and teeth spacing are set。

As shown in Figure 1, Figure 2 and shown in Fig. 7, described adjustment fixed mechanism 60 includes running through regulating fixing threaded hole 63 and fixing bolt 64 with regulating the adjustment that fixing threaded hole 63 mate of outer sleeve 62 1 side tube-wall。The fixing bolt 64 of described adjustment to regulate fixing threaded hole 63 screw in time, the interpolation pole 61 being nested with in outer sleeve 62 can be fixed temporarily。

When needing the interpolation pole 61 being nested with in outer sleeve 62 is fixed, regulate fixing bolt 64 to regulating screw-in in fixing threaded hole 63 temporarily, make the head end of the fixing bolt 64 of adjustment hold interpolation pole 61 surface being fixed in outer sleeve 62 and reach fixed effect。

Further, as shown in Figure 1, Figure 2 and shown in Fig. 4, some with the interpolation pole 61 cross section parallel ring-shaped depressions spaced apart along major axis of surface configuration of described interpolation pole 61。The A/F of described ring-shaped depression is more than regulating fixing bolt 64 head end external diameter, and the bottom width of ring-shaped depression is less than regulating fixing bolt 64 head end external diameter。When regulating fixing bolt 64 and screwing in adjustment fixing threaded hole 63, the head end regulating fixing bolt 64 can set and hold bottom ring-shaped depression。

The setting of described ring-shaped depression makes adjustment fixing bolt 64 can hold the bottom at ring-shaped depression when screwing in, thus strengthening playing stiffening effect to the interpolation pole 61 being nested with in outer sleeve 62 is highly fixing。Because traction force is excessive when avoiding actually used, regulating fixing bolt 64 and the frictional force holding generation of interpolation pole 61 is not enough to antagonism, cause interpolation pole 61 in use to glide in outer sleeve 62, cause operation tractive height to decline, otch exposure effect is deteriorated。

The A/F of described ring-shaped depression is more than regulating fixing bolt 64 head end external diameter, and the bottom width of ring-shaped depression is less than regulating fixing bolt 64 head end external diameter。So, regulate head end just holding when fixing bolt 64 is screwed into greatest extent and, in the depressed area of described ring-shaped depression, the strength that holding is fixing can be promoted to greatest extent, it is prevented that in use, interpolation pole 61 glides in outer sleeve 62。Further, regulate fixing bolt 64 and screw in, in order to improve, the dynamics in outer sleeve 62, interpolation pole 61 highly fixed, it is possible to some annular lines parallel with interpolation pole 61 cross section are set in ring-shaped depression。

As shown in Figure 1, Figure 2 and shown in Fig. 7, fixing fixture block 41 that described cross bar fixed mechanism 4 includes being arranged at cross bar fixed arm 3 lower end and be movably arranged on cross bar fixed arm 3 the adjustment fixture block 42 that can mate with fixing fixture block 41, regulates described adjustment fixture block 42 and operation table edge rail temporary card can be made to fasten at fixing fixture block 41 and regulate between fixture block 42。

Described fixing fixture block 41 and adjustment fixture block 42 are correspondingly arranged, formation opening is narrow and small, the form that back space is bigger, and the catch surface of fixing fixture block 41 and adjustment fixture block 42 correspondence is preferably arranged to arc or oblique, two corresponding catch surface are made to form opening narrow and small, the form that back space is bigger。So, when adjusting adjustment fixture block 42 and moving clamping operation table edge rail to fixing fixture block 41, operation table edge rail posteriorly closes clamping wall under the arc of fixing fixture block 41 and adjustment fixture block 42 correspondence or the effect of oblique catch surface and slides, forming the steady statue of three stress, fixed effect is greatly improved。

Such as Fig. 1, Fig. 2, shown in Fig. 7 and Fig. 9, described cross bar fixed mechanism 4 also includes being arranged on the adjusting rod 43 for promoting adjustment fixture block 42 to move that adjustment fixture block 42 dorsal part is connected as a single entity, at least two arranges the pilot hole 40' guiding projection 40 for adjusting rod 43 moving direction that leads with the fixing middle part being connected of cross bar fixed arm 3, for preventing the middle part that adjusting rod 43 reversely moves from arranging the hole mated with adjusting rod 43 external diameter and free activity is nested with on adjusting rod 43 and brakes orifice plate 44, to the unilateral mobile spacing spring one side limited block 45 of braking orifice plate 44, the be connected middle part that be positioned at adjustment fixture block 42 dorsal border fixing with cross bar fixed arm 3 arranges hole the spring dead plate 49 being nested with on adjusting rod 43, the compression spring 46 being nested with on adjusting rod 43 between brake hole plate 44 and spring dead plate 49。Described braking orifice plate 44 is nested with on adjusting rod 43 between spring one side limited block 45 and spring dead plate 49。

Braking the stop by spring one side limited block 45 of orifice plate 44 side time static, under compression spring 46 active force, braking orifice plate 44 tilts to greatest extent to spring one side limited block 45 offside, and braking orifice plate 44 forms minimum limit angle 47 with adjusting rod 43。

When promote adjusting rod 43 make the adjustment fixture block 42 of head end side to fixing fixture block 41 near time, compression spring 46 is compressed further under frictional force effect, making the angle 47 between braking orifice plate 44 and adjusting rod 43 become big, resistance diminishes, and regulates fixture block 42 and moves to fixing fixture block 41。

When regulating fixture block 42 and being subject to making adjusting rod 43 have away from fixing fixture block 41 trend from the strength of operation table edge rail, angle 47 has the trend of reduction further, but owing to braking orifice plate 44 central aperture stress edge 48 has reached the limit with adjusting rod 43 contact angle, make braking orifice plate 44 and adjusting rod 43 form angle 47 cannot reduce further, thus preventing adjusting rod 43 reversely to move, fixing fixture block 41 and adjustment fixture block 42 is finally made firmly to be clamped in operation table edge rail upper and lower sides。

During enforcement, described guiding projection 40 arranges number at least two, and the pilot hole 40' in the middle part of two guiding projections 40 is in on pilot hole 40' week axis line。The interior cross section of some pilot hole 40' and the cross section of adjusting rod 43 match and slightly larger than the cross section of adjusting rod 43, make adjusting rod 43 can be nested with in some pilot hole 40' and translate along major axis。Described adjustment fixture block 42 is arranged on adjusting rod 43 and closes on the top of fixing fixture block 41, regulates fixture block 42 to fixing fixture block 41 close at first with fixing fixture block 41 after making adjusting rod 43 move。

The intracavity section of described pilot hole 40' is preferably non-circular with the cross section of adjusting rod 43, it is to avoid adjusting rod 43 rotates time mobile to fixing fixture block 41 under the inner chamber of some pilot hole 40' guides and causes that the angle of adjustment fixture block 42 offsets。For simple enforcement, the intracavity section of described pilot hole 40' is preferably rectangular with the cross section of adjusting rod 43, and adjusting rod 43 should be nested with in the vestibule of some pilot hole 40'。

As shown in Figure 8, the brake hole in the middle part of described braking orifice plate 44 is preferably arranged to noncircular cross section, and first-selection is cross section and the adjusting rod 43 cross section Similar size shape slightly larger than adjusting rod 43 cross section。Described braking orifice plate 44 should be nested with on adjusting rod 43, between spring one side limited block 45 and spring dead plate 49。Described spring one side limited block 45 should be located remotely from the side regulating fixture block 42, and spring dead plate 49 should be positioned at and close on the side regulating fixture block 42。In embodiment shown in this figure, spring dead plate 49 and one of them guiding projection 40 are same structure。The recovery length of described compression spring 46 should be greater than the distance between spring one side limited block 45 and spring dead plate 49, and compression spring 46 compression is arranged between braking orifice plate 44 and spring dead plate 49。

As it is shown in figure 9, during resting state, compression spring 46 closes on spring dead plate 49 spring regulating fixture block 42 side and cannot stretch, restoring under elastic acting force after compression spring 46 compression, described braking orifice plate 44 moves to away from the direction regulating fixture block 42 side。When braking orifice plate 44 and suffering from spring one side limited block 45, braking orifice plate 44 closes on limited block 45 side, spring one side and cannot continue to move along, and brakes orifice plate 44 and can continue somewhat to move forward under spring restitutive force away from limited block 45 side, spring one side。Until the hole in the middle part of braking orifice plate 44 closes on the central aperture stress edge 48 of limited block 45 side, spring one side lower edge and the central aperture stress edge 48 away from limited block 45 side, spring one side upper limb and distinguishes holding in the both sides of adjusting rod 43, form the brake force of distortion, braking orifice plate 44 forms minimum limit angle 47 with adjusting rod 43, making braking orifice plate 44 cannot regulate fixture block 42 further away from each other to move, braking orifice plate 44 cannot deflection further simultaneously。

When adjustment fixture block 42 and fixing fixture block 41 are adjusted near and clamping operation table edge rail by needs, fixture block 42 and fixing fixture block 41 holding respectively will be regulated at the upper and lower sides of operation table cross bar, adjusting rod 43 is promoted to fixing fixture block 41 direction, now compression spring 46 is compressed further under frictional force effect, the angle 47 between braking orifice plate 44 and adjusting rod 43 is made to become big, frictional resistance diminishes, regulate fixture block 42 close to fixing fixture block 41, until regulating fixture block 42 and fixing fixture block 41 by operation table cross bar clamping。

When regulating fixture block 42 and being subject to making adjusting rod 43 have away from fixing fixture block 41 trend from the strength of operation table edge rail, braking orifice plate 44 has the trend of inclination further, angle 47 is made to have the trend of reduction further, but owing to braking orifice plate 44 central aperture stress edge 48 has reached the limit with adjusting rod 43 contact angle, braking orifice plate 44 defines minimum limit angle 47 already with adjusting rod 43 under the effect of compression spring 46, angle 47 cannot reduce further, thus preventing adjusting rod 43 reversely to move, move thus avoiding adjustment fixture block 42 to the direction away from fixing fixture block 41, the operation table edge rail upper and lower sides edge that is held in tightly ensure that in operation, tractive exposes the stability of otch。

When operation terminates to take off described height adjustable universal fixing drag hook, only need to press downwards brake hole plate 44 with finger away from limited block 45 side, spring one side, spring is made to be compressed further, the angle 47 between braking orifice plate 44 and adjusting rod 43 is made to become big, frictional resistance diminishes, adjusting rod 43 can be extracted to the direction away from fixing fixture block 41, make holding deviate from the operation table cross bar regulated between fixture block 42 and fixing fixture block 41。

In a word, this utility model is applied at surgical operation, can be temporarily fixed on surgical head rest cross bar by the porous belts drag hook blade 1 of the duty of multiple angles simply and easily, alleviate doctor's workload, simple in construction, and easy to use, effect is safe and reliable。
