Abstract
The utility model discloses a difunctional chuck, the medical instrument technical field who belongs to combination formula external fixation, be applicable to fixed the reseing of four limbs fracture or basin bone fracture, a clamp is multi -purpose not only to be saved operating time but also alleviates patient's economic burden, two pole list needle holder heads or the single pole two needle holder heads of suitable quantity are selected according to the operation needs, a two pole list needle holder head, a pole mount that makes up formula external fixation frame before being equivalent to adds a needle bar fixation clamp, before being equivalent to, make up on the two needle holder heads of single pole two needle bar fixation clamps of formula external fixation frame, pursue under the simple swift theory at current medical instrument, the utility model discloses a satisfy the product of this kind of theory.
Description
Technical field
This utility model relates to shank or the bar bar cramp head of mixed external fixator, belongs to extenal fixation technical field of medical instruments, is the extenal fixation product fixing rehabilitation after extremity fracture.
Background technology
Mixed external fixator is more and more widely used, along with increasing of using, find that the limitation that portioned product uses also gets more and more, shank chuck in picture mixed external fixator or bar bar cramp head, there is certain reasonability but also there are some drawbacks simultaneously, when there are two pitmans at needle rod holder place and cannot fix other bar bar cramp head, the chuck of mixed external fixator in the past just cannot meet the function that a chuck can press from both sides two pitmans spicule simultaneously, or a chuck connects a pitman, the function of two spicules, on this basis, my company is suitable for the two bar single needle chuck or crosspointer single pole chuck better selecting more easily to design.
Summary of the invention
Simultaneously this utility model coordinates the connecting rod in mixed external fixator and spicule to complete an extenal fixation operation technique, and design comparison of the present utility model is reasonable, and practicality simple to operate, is applicable to applying.
The technical solution of the utility model is as follows:
This utility model is difunctional chuck, by manual knob (4), upper fixture block (5), lower fixture block (6), common formation, it is characterized in that: upper fixture block (5) can press from both sides two pitmans (1) with lower fixture block (6) simultaneously, a spicule (3), or press from both sides two spicules (3) simultaneously, a pitman (1), save regular time or space, upper fixture block (5) the right and left can press from both sides a pitman (1), a spicule (3), also can press from both sides two spicules (3) simultaneously, reduce an independent needle rod holder or bar bar cramp, facilitate the operation of doctor, reduce the economic cost of patient.The usage fixedly saving a spanner of upper and lower fixture block, direct hands twists manual knob (4), fixture block (5) in compression, upper fixture block (5) compresses the spring between two fixture blocks, along with the distance of manual knob (4) turn is downwards more and more less, under the elastic force effect of spring, be fixedly connected with rod (1) or spicule (3).The shank of manual knob (4) is straight knurling, facilitates turn-knob to increase feel again, the eccentric shaft of shank center hexagonal hole, can be locked with a hexagon, saves complicated operation tool.
This utility model compared with prior art has the following advantages:
1 one folder dual-purposes are saved time minimizing expense;
2 hand Screws, eccentric locked, convenient and swift;
3 lock portions adopt titanium alloy material performance better.
Accompanying drawing explanation
Fig. 1 is the extenal fixation overall schematic after this utility model combination.
Fig. 2 is of the present utility model pair of bar single needle clamping structure schematic diagram.
Fig. 3 is single pole crosspointer clamping structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Doctor is according to patients with fractures's situation, select suitable molectron, there is the pitman (1) of suitable quantity specification, difunctional chuck (2) (selecting two bar single needle chuck or single pole crosspointer chuck as required), spicule (3), first be screwed into spicule (3) according to affected part situation, spicule (3) is inserted in suitable multi-functional chuck (2), turn manual knob (4), fixed bone spicule (3), connect between spicule with pitman (1) again, the clamping bar groove of multi-functional chuck (2) is put at the two ends of pitman (1) respectively, finally screw the hexagonal hole of manual knob (4) shank, locked whole combination type extenal fixation operation technique.
Claims (2)
1. this utility model is difunctional chuck, by manual knob (4), upper fixture block (5), lower fixture block (6), jointly form, it is characterized in that: upper fixture block (5) can press from both sides two pitmans (1) and a spicule (3) simultaneously with lower fixture block (6) or press from both sides two spicules (3) and a pitman (1) simultaneously.
2. the difunctional chuck according to claims 1, the feature of manual knob (4) is: the shank of manual knob (4) is straight knurling, facilitate turn-knob to increase feel again, the eccentric shaft of shank center hexagonal hole, can be locked with a hexagon.
