Description

Knee joint replacement support

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a knee joint replacement bracket.

Background

At present, the TKA operation for total knee joint surface replacement needs to keep the knee joint bent in the process of osteotomy operation so as to expose the osteotomy surface needed by the femur and the tibia, especially in the process of femur, tibia osteotomy and prosthesis installation, the knee joint of the affected limb of a patient needs to be bent and is perpendicular to the bed surface, an assistant is needed to fix the affected limb in the whole course in the operation process, the deviation of femur or tibia osteotomy is probably caused by long operation time and easy fatigue in free hand, and the unreliable fixation of the affected limb, so that the lateral installation of the knee joint femur and tibia prosthesis and the correction of the force line of the affected limb are influenced, and finally, operation errors are caused, and the postoperative curative effect of the affected limb is influenced.

To solve the problem, chinese patent publication No. CN202173556U discloses a knee joint support frame in 03 month 28 of 2012, which includes an operating table card and an L-shaped support frame, wherein the cross section of the operating table card is C-shaped, an opening of the C-shaped cross section corresponds to a standard operating table side fixing frame, the operating table card is clamped on the operating table side fixing frame, and a height adjusting structure is arranged on the operating table card; the first edge of the L-shaped support frame is movably connected with the height adjusting structure, and the second edge of the L-shaped support frame is connected with the lower limb support piece. Therefore, the leg of the patient can not be fixed and can move in the operation, the leg of the patient can not be adjusted in the left-right direction according to the operation requirement, the telescopic angles of the thigh and the shank can not be adjusted and fixed, and the like, so that the problems of long operation time, much bleeding, more needed medical staff and inconvenience in use are caused.

Disclosure of Invention

The invention aims to overcome the defects and provide a knee joint replacement bracket which has short operation time, less bleeding, less required medical staff and convenient use.

The purpose of the invention and the main technical problem of solving the invention are realized by adopting the following technical scheme:

the invention relates to a knee joint replacement bracket, which comprises a support frame A, a fixing frame, a support frame B and a fixing rod, wherein: the supporting frames A and B are door-shaped frames, and the cross beam A and the cross beam B are provided with a plurality of clamping grooves; two ends of the fixed rod are respectively clamped on the cross beam A and the cross beam B, and the fixed frame is sleeved on the fixed rod; the mount includes horizontal pole A, snap ring, checkpost A, horizontal pole B, frid, lantern ring A, bottom plate, the lantern ring B and checkpost B, and lantern ring A, lantern ring B are fixed in frid bottom both sides, are equipped with the bottom plate between lantern ring A, the lantern ring B bottom, and horizontal pole A one end is fixed on lantern ring A, and horizontal pole B one end is fixed on lantern ring B, and the snap ring both ends block respectively on horizontal pole A, horizontal pole B and block fixedly with checkpost A, checkpost B respectively.

Two through holes are respectively arranged on two sides of the clamping ring.

Two through holes are respectively arranged on two sides of the upper part of the groove plate.

The transverse rods A and B are provided with clamping grooves.

Compared with the prior art, the invention has obvious beneficial effects, and the technical scheme shows that: the two ends of the fixed rod are respectively clamped on the cross beam A and the cross beam B, the fixed rod can be adjusted forwards and backwards as required, the affected limb can be fixed according to the required position, and the fixed frame is sleeved on the fixed rod and can move left and right, so that the legs of the patient on the fixed frame can move left and right along with the fixed frame; the height of the knee joint of a patient in an operation is improved and blood loss in the operation is reduced by adjusting the height of the fixing rod on the cross beam A and the cross beam B. The two ends of the clamp ring are respectively clamped in the clamping grooves on the cross rod A and the cross rod B and are fixed by the clamp A and the clamp B, and the required telescopic angle can be obtained by adjusting the positions of the clamp ring on the cross rod A and the cross rod B according to the requirements of the operation; after the affected limb of the patient is fixed, the invention can move left and right and can adjust the stretching angle of the thigh and the shank according to the operation requirement, thereby shortening the operation time, reducing bleeding, requiring less medical staff and being convenient to use.
