Abstract

The finger replantation fixation frame is a medical device, which is mainly suitable for the treatment of patients with amputated or severed fingers. During the operation, the severed finger is inserted into the finger fixing hole of appropriate thickness, and the replantation can be performed after it is firmly fixed; when cleaning the proximal end of the severed finger and anastomosing the blood vessels and nerves, the affected hand is unfolded and placed flat on the replantation board operating table. The side grooves on both sides are used to hang rubber strips. The corresponding fingers, palms, and wrists are fixed as needed, and then the severed finger replantation operation can be performed. After the operation, the severed limb replantation board can be supported into a triangular bracket, and the patient puts the affected hand on the middle board. The angle can be changed as needed, and perspective can be performed during the operation to check the anastomosis of the bones, blood vessels, and tendons of the affected hand. It is easy to use and simple to operate, making the surgical treatment of severed finger replantation simpler, faster, and more effective, greatly reducing the difficulty and time of the operation, and filling an international gap.

Description

Technical Field

[0001] The invention relates to the technical field of medical devices and is a fixing frame used for replantation of severed fingers. Background Art

[0002] At present, patients with amputated or severed fingers need to undergo finger replantation surgery under a microscope. During the operation, bandage traction, clamping, and assistant's two-hand clamping are generally used to stabilize the patient's injured hand. As for the severed finger, due to its small size, it also needs to be stabilized by the assistant's two-hand clamping. Since the operative field of microsurgery is narrow and the operation is delicate, the stability of the operative field and the coordination of the position of the affected finger are extremely high. Due to the shaking and movement of the assistant's hands, it is more difficult to maintain its stability, especially when holding for a long time, which brings great instability to the surgeon and even affects the effect of the operation.

[0003] Therefore, it is necessary to provide a new fixation device to solve the above problems and make the treatment of severed finger replantation more simple, rapid and effective. Summary of the invention

[0004] The purpose of the present invention is to solve the deficiencies in the above-mentioned prior art and to provide a severed finger replantation fixation frame which can firmly fix the patient's injured hand.

[0005] The front side of the upper plate of the present invention is perforated at positions corresponding to both sides of the fingers according to the shape of an adult's open hand, and the diameters of the circular holes are different. During an operation, the severed finger replantation fixation frame is sterilized in advance and placed on the operating table, the replantation plate is placed with the plane facing upward, the affected hand is spread out and placed flat on the replantation plate, and the side grooves on both sides are used to hang rubber strips, and the corresponding fingers, palms and wrists are fixed as needed, thereby reducing ineffective surgical operations caused by involuntary movements of the affected limbs, significantly shortening the operation time, reducing the physical and mental consumption of medical staff, and improving the operation efficiency.

[0006] When the wound needs to be flushed, the leakage holes on the board surface and other finger-fixed holes can allow the wound bleeding and flushing saline to seep downward to the bottom of the replantation board to keep the surgical field clean and avoid excessive fluid accumulation during surgery that would hinder the operation.

[0007] The beneficial effect of the present invention is that the fixing frame is placed flat on the operating table, the injured hand is not raised during the operation, which is conducive to the stability of the operator's operation. The injured hand and fingers can be fixed on the fixing frame at any location according to the need, and can be adjusted at any time. The operation is convenient and greatly improves the efficiency of the operation. After the operation, the broken limb replantation board can be supported into a triangular bracket. The patient puts the injured hand on the middle board, and the angle can be changed according to the need. The perspective can be performed during the operation to check the anastomosis of the bones, blood vessels and tendons of the injured hand to judge whether the replantation is successful or not.

[0021] Specific implementation method: During the operation, the finger replantation fixation frame is disinfected in advance and placed on the operating table, and the replantation board is placed with the plane facing upward. When debridement of the distal end of the finger, the finger is inserted into a finger-fixing hole of appropriate thickness, and the replantation operation can be performed after it is firmly fixed; when debridement of the proximal end of the finger and anastomosis of blood vessels and nerves are performed, the affected hand is spread out and placed flat on the replantation board, and the side grooves on both sides are used to hang rubber strips. The corresponding fingers, palms, and wrists are fixed as needed, and then the finger replantation operation can be performed. After the operation, the limb replantation board can be supported into a triangular bracket, and the patient puts the affected hand on the middle board. The angle can be changed as needed, and fluoroscopy can be performed during the operation to check the anastomosis of the bones, blood vessels, and tendons of the affected hand to determine whether the replantation operation is successful.

Claims

1. A fixation frame for replantation of severed fingers, comprising three fixed flat plates, which are connected to each other by hinges, that is, folded and interlocked to support, and are divided into upper, middle and lower layers when folded, and all three layers are rectangular straight plates; the upper plate has two sides bent into 90-degree folds facing the same direction, and the folds on each side have different numbers of inverted circular tooth-shaped notches, through which the bandage for binding the affected hand is passed, and the front of the plate has finger holes in the shape of an adult's unfolded hand, and the diameters of the fixed finger holes are different. There are multiple small circular holes on the edges of the two sides of the fixing plate, so that the surgical environment is clean and blood and flushing water flow down the holes; the middle layer; the lower layer is an ordinary rectangular plate, and the three layers of plates are folded to support to form a triangular bracket; The material is carbon fiber, which is strong, durable, and easy to store and disinfect; The two sides of the fixing plate are bent in the same direction to form 90-degree folds, and there are different numbers of rounded tooth-shaped notches on each fold. The bandage used to bind the affected hand is passed through, and the bandage is wrapped around the appropriate part of the palm and passed through the rounded tooth-shaped notches to be tied tightly. The front of the fixing plate has finger holes in the shape of an adult's open hand. The diameters of the holes are different. Multiple diameters of the holes are widely used in severed finger replantation surgery. There are multiple circular holes on the fixing plate and the edges on both sides to keep the surgical environment clean and allow blood and flushing water to flow down the holes. When the three boards are folded and propped up, they form a triangular bracket to fix the affected limb for fluoroscopic examination.
