Abstract
The invention discloses an auxiliary limiting device for a knee joint operation, and belongs to the technical field of medical instruments. The device comprises a thigh fixing clamping plate (1), a shank fixing clamping plate (4), a flexion and extension adjusting device (12) and a turning adjusting device (13). The flexion and extension adjusting device is composed of a flexion and extension adjusting nut (8), a large clamping plate connecting piece shaft sleeve (9), an adjusting shaft (10) and a small clamping plate connecting piece shaft sleeve (11). The turning adjusting device (13) is composed of a screw (5) and a turning adjusting nut (6). The thigh fixing clamping plate (1) is connected with the large clamping plate connecting piece shaft sleeve (9) of the flexion and extension adjusting device (12) through a large clamping plate connecting piece (3). The turning adjusting device (13) is connected with the small clamping plate connecting piece shaft sleeve (11) of the flexion and extension adjusting device (12) through a small clamping plate connecting piece (7). The auxiliary limiting device has the advantages of being simple in structure, convenient to operate, capable of saving operation time and adjusting the flexion and extension and inward and outward turning angles of the knee joints and the like.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of auxiliary stopper device of hospital orthopedics knee surgery.
Background technology
In knee surgery, doctor's moment requires that patient legs is fixed on different positions passively, knee joint can be fixed on a kind of ideal position owing to there is no special aid in prior art, therefore 1-2 name Physician's Assistant is needed in operation, be responsible for fixing suffering limb specially, the shank of patient, according to the requirement of operation, is put the posture of needs and keeps this posture to end of performing the operation by Physician's Assistant.Which not only adds operation cost, the financial burden of making patients, and the doctor being responsible for fixing keeps the meeting of same posture easily tired for a long time, therefore the fixed position of patient can be changed, knee joint is caused to be in an unsure state, cause operation technique easily to occur error, operation technique need carry out repeatedly.On the other hand, be responsible for fixing Physician's Assistant often to need, near patient, especially to need the position of having an operation, so also can hinder doctor's operation apparatus of operator, bring inconvenience to operation.
Summary of the invention
For prior art above shortcomings, the object of this invention is to provide a kind of structure simple, easy to operate, can save operating time, can flexible knee joint bend and stretch and inside and outside upset angle, the auxiliary stopper device of location of operation precision can be improved.
For achieving the above object, the present invention adopts following technical proposals: a kind of knee surgery auxiliary stopper device, comprise thigh strap, shank strap and adjusting device, it is characterized in that: described thigh strap and shank strap are the coniform of hollow, described adjusting device comprises bends and stretches adjusting device and upset adjusting device, described bends and stretches adjusting device by bending and stretching adjusting nut, big clamp plate brace axle sleeve, regulating shaft and plintlet brace axle sleeve composition, described bends and stretches one end that adjusting nut is fixed on regulating shaft, described regulating shaft is through big clamp plate brace axle sleeve and plintlet brace axle sleeve, described upset adjusting device is located at the upper end of shank strap, upset adjusting device is made up of screw rod and upset adjusting nut, the left end of described thigh strap is connected with the big clamp plate brace axle sleeve bending and stretching adjusting device by big clamp plate brace, described upset adjusting device is connected with the plintlet brace axle sleeve bending and stretching adjusting device by plintlet brace, described thigh strap and shank strap are equipped with bundling belt and band mouth.
The inside of thigh strap of the present invention and shank strap is equipped with the liner that soft material is made.
Compared with prior art, beneficial effect of the present invention has:
1, by thigh strap and shank strap, bend and stretch adjusting device and upset adjusting device, thigh can be made to keep relatively-stationary position, and flexible can be carried out to bending and stretching of shank with inside and outside flip angle, knee joint difference be can be locked in by doctor's requirement like this and angle and inside and outside flip angle bent and stretched, improve location of operation precision, avoid the unexpected generation of operation.
2, The present invention reduces operation number, decrease the burden of Medex, reduce operation cost, but also be convenient to operation carry out smoothly, save operating time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is thigh strap of the present invention and the structural representation bending and stretching adjusting device and be connected.
Fig. 3 is the structural representation that shank strap of the present invention is connected with upset adjusting device.
In figure, 1-thigh strap, 2-is with mouth, 3-big clamp plate brace, 4-shank strap, 5-screw rod, 6-overturns adjusting nut, 7-plintlet brace, and 8-bends and stretches adjusting nut, 9-big clamp plate brace axle sleeve, 10-regulating shaft, 11-plintlet brace axle sleeve, 12-bends and stretches adjusting device, 13-overturns adjusting device, 14-bundling belt.
Detailed description of the invention
As shown in Figures 1 to 3, a kind of knee surgery auxiliary stopper device of the present invention, comprise thigh strap, shank strap, bend and stretch adjusting device and upset adjusting device, thigh strap and shank strap are the coniform of hollow.Bend and stretch adjusting device by bending and stretching adjusting nut, big clamp plate brace axle sleeve, regulating shaft and plintlet brace axle sleeve composition, bend and stretch one end that adjusting nut is fixed on regulating shaft, regulating shaft is through big clamp plate brace axle sleeve and plintlet brace axle sleeve, upset adjusting device is located at the upper end of shank strap, upset adjusting device is made up of screw rod and upset adjusting nut, the left end of thigh strap is connected with big clamp plate brace axle sleeve by big clamp plate brace, upset adjusting device is connected with the plintlet brace axle sleeve bending and stretching adjusting device by plintlet brace, thigh strap and shank strap are equipped with 2 bundling belts and 2 band mouths, can be provided with by sponge in thigh strap and shank strap, the liner that the soft material such as resin or plastics is made.
When the present invention uses, thigh is limited on thigh strap by bundling belt and band mouth, keep a relatively-stationary position, shank is limited on shank strap by bundling belt and band mouth, shank strap is by bending and stretching the degree of bending and stretching before and after adjusting device adjustment shank, bend and stretch adjusting nut by degree of tightness during adjustment, make plintlet brace axle sleeve on regulating shaft, overturn the degree of bending and stretching controlled before and after shank.Shank strap also adjusts the varus and valgus angle of shank by upset adjusting device, adjusting nut is overturn by degree of tightness during adjustment, make plintlet brace on screw rod, overturn the angle controlling to overturn inside and outside shank, make knee joint be fixed on a kind of ideal position state.The present invention does not need Physician's Assistant to fix suffering limb, decreases operation number, reduces operation cost, but also is convenient to operation and carries out smoothly, has saved operating time, has improve location of operation precision, avoiding that operation is unexpected to be occurred.
Aid of the present invention is applicable to laparoscopic surgery, and after replacement knee in arthroplasty and various knee joint, short-term is fixed.
