Abstract
Annular acetabular bone muscle device for spreading, is related to medical instruments field, and especially a kind of distraction angle is big, convenient for the annular acetabular bone muscle device for spreading of operation.The utility model includes strutting ring and strutting hook, strutting ring is two, in minor arc shape, strutting hook is two, it struts the fixation of ring one end and struts hook, have zigzag raised on other end side wall, the zigzag protruding end that one of them zigzag protruding end for strutting ring struts ring with another, which connects and composes, struts annulus, annulus is strutted in major arc shape, two strut hook and are located at and strut on the outside of annulus.The utility model struts ring by two and struts the muscle covered on acetabular bone, and it is mutually twisted using the zigzag protrusion for strutting ring connecting portion, fixation struts size, finishing operation can be carried out, operation can be completed in a doctor, in the course of surgery, it fully relies on zigzag protrusion and carries out snap-in location, it is time saving and energy saving, it is not only able to improve quality of medical care, moreover it is possible to reduce operating difficulty.
Description
Technical field
The utility model relates to medical instruments field, especially a kind of distraction angle is big, convenient for the annular acetabular bone flesh of operation
Meat device for spreading.
Background technique
Artificial hip joint replacing is that a kind of similar people is made with the metal material of biocompatibility and satisfactory mechanical property
The prosthese and acetabular cup of body Bones and joints are replaced acetabular cup in the acetabular fossa destroyed by disease or injury using operation method,
The purpose is to removal of lesions, remove pain, restore the activity and original function in joint.Acetabular cup displacement have joint motion compared with
It is good, can early stage Go to ground activity, the advantages that reducing the complication of elderly patients' long-term bed.
The accurate positionin of hip joint center is the outstanding feature one of successful surgery in the operation of orthopaedics full hip-joint, but
In complicated total hip arthroplasty, such as adult acetabular fossa depauperation, Treatment of Ankylosed Hips, acetabular revision, true mortar nest is by spur
Covering, acetabular development is abnormal, bone mark changes etc., and factors above often results in the in irregular shape of acetabular fossa, and manual acetabulum
Cup is generally industrialized mass production, and shape, size are unified, if desired because people customizes, then can increase operation cost, increase
Add patient to bear, while also as wait dedicated acetabular cup and extend operation the waiting time, be unfavorable for patient recovery.
Therefore, before replacement operation, it will usually be modified with file to acetabular fossa shape, so that acetabular fossa shape tends to
Standard is convenient for directly by manual acetabulum cup implantation therein, currently, usually using tweezers by a doctor in the finishing operation
The muscle covered on acetabular bone is strutted, is then modified by another doctor, but the muscle of acetabular bone surface covering is thicker,
Great efforts are sprung back, when strutting, needs to be kept the opening angle of tweezers with biggish power, increases the difficult journey in surgical procedure
Degree, be easy to cause operative failure, and operation at least needs two doctor's operations on the scene every time, wastes medical resource.
Summary of the invention
To be solved in the utility model is exactly that the flesh covered on acetabular bone is strutted by tweezers in acetabular bone trimming operation
The problem of meat, opening angle is small, keeps difficult, is unfavorable for operation, provides that a kind of distraction angle is big, convenient for the annular acetabular bone of operation
Muscle device for spreading.
The annular acetabular bone muscle device for spreading of the utility model, it is characterised in that the device for spreading includes strutting ring and strutting
Hook, strutting ring is two, is in minor arc shape, and strutting hook is two, struts the fixation of ring one end and struts hook, other end side wall
On have that zigzag is raised, one of them zigzag protruding end for strutting ring connect structure with the zigzag protruding end that another struts ring
At annulus is strutted, annulus is strutted in major arc shape, two strut hook and are located at and strut on the outside of annulus.
The device for spreading is additionally provided with connection sleeve, and connection sleeve is sleeved on two link positions for strutting ring.
Described strutting is provided with circular hole on two ends of annulus, in surgical procedure, fixed pin can be solid across circular hole
It is scheduled on acetabular bone periphery.
In the course of surgery, first by the Muscle disruption on acetabular bone surface, then the hook that struts at device for spreading both ends is inserted into
Muscle lower layer, both hands hold two respectively and strut ring, pull open outward, during pulling open, strut hook muscle is outside together
It struts, when distraction angle is enough, the zigzag protrusion for strutting ring junction using two is mutually twisted, and can be fixed and be strutted ruler
It is very little, acetabular bone finishing is carried out, when needed, moreover it is possible to which fixed pin is fixed across the circular hole for strutting the setting of annulus two ends.
The annular acetabular bone muscle device for spreading of the utility model, design science, structure is simple, easy to use, passes through two
It struts ring to strut the muscle covered on acetabular bone, and is mutually twisted using the zigzag protrusion for strutting ring connecting portion, rigid staybolt
Size is opened, finishing operation can be carried out, operation can be completed in a doctor, in the course of surgery, fully relies on zigzag protrusion
Snap-in location is carried out, it is time saving and energy saving, it is not only able to improve quality of medical care, moreover it is possible to reduce operating difficulty.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the utility model side structure schematic diagram.
Wherein, ring 1 is strutted, hook 2, zigzag protrusion 3, circular hole 4 are strutted.
Specific embodiment
Embodiment 1: a kind of annular acetabular bone muscle device for spreading, including strut ring 1 and strut hook 2, strutting ring 1 is two
It is a, it is in minor arc shape, strutting hook 2 is two, struts the fixation of 1 one end of ring and struts hook 2, has zigzag convex on other end side wall
3 are played, raised 3 ends of zigzag that one of them raised 3 end of zigzag for strutting ring 1 struts ring 1 with another, which connect and compose, to be strutted
Annulus, struts annulus in major arc shape, and two strut hook 2 and are located at and strut on the outside of annulus.Device for spreading is additionally provided with connection sleeve,
Connection sleeve is sleeved on two link positions for strutting ring 1.It struts and is provided with circular hole 4, surgical procedure on two ends of annulus
In, fixed pin can pass through circular hole 4 and be fixed on acetabular bone periphery.
In the course of surgery, first by the Muscle disruption on acetabular bone surface, then the hook 2 that struts at device for spreading both ends is inserted into
Muscle lower layer, both hands hold two respectively and strut ring 1, pull open outward, during pulling open, strut hook 2 by muscle together to
It struts outside, when distraction angle is enough, the zigzag protrusion 3 for strutting 1 junction of ring using two is mutually twisted, can rigid staybolt
Size is opened, carries out acetabular bone finishing, when needed, moreover it is possible to be consolidated fixed pin across the circular hole 4 for strutting the setting of annulus two ends
It is fixed.
