Spreading fixator for liver transplantation operation

Abstract

The invention discloses a spreading fixator for a liver transplantation operation. The spreading fixator comprises a connecting rotating shaft, mounting handles, mounting holes, supporting handles, fixing rods, locking reeds, spreading teeth, protection pads, positioning teeth, a supporting spring, a holding block, an adjusting sleeve, a screw port, an adjusting screw, a handle and transition pads. The spreading fixator has the advantages that the angle between the mounting handles can be freely adjusted under driving of the adjusting screw, an incision can be supported by any angle, different incisions can be adapted to through self-adjustment, the supporting spring can apply outward elastic force to the mounting handles at the two sides, outward supporting force can be provided for the mounting handles, the situation that the angle between the two mounting handles is reduced due to the shrinkage of the incision is prevented, and thus a good supporting effect is achieved. The supporting handles can be freely detached and installed from the mounting handles, free disassembly can be conducted, and disinfection in the later period is facilitated.

Description

technical field [0001] The invention relates to a spreader, in particular to a spreader for liver transplantation, and belongs to the field of medical equipment. Background technique [0002] At present, in the medical liver transplant operation, the abdominal wall needs to be incised, but often due to the strong contraction force of the muscles, the incision that is too small is easy to close automatically, which will reduce the surgical field of view. If a clear surgical field of view is required, the surgical field must be enlarged passively The incision will inevitably increase the trauma of the patient, which is not conducive to postoperative recovery. A good surgical field of view is the basic condition to ensure the operation. Equipment is needed to help the medical staff to open the incision, so as to help the medical staff perform the operation.

Problems solved by technology

[0002] At present, in the medical liver transplant operation, the abdominal wall needs to be incised, but often due to the strong contraction force of the muscles, the incision that is too small is easy to close automatically, which will reduce the surgical field of view. If a clear surgical field of view is required, the surgical field must be enlarged passively The incision will inevitably increase the trauma of the patient, which is not conducive to postoperative recovery. A good surgical field of view is the basic condition to ensure the operation. Equipment is needed to help the medical staff to open the incision, so as to help the medical staff perform the operation. If the incision cannot be opened Otherwise, the operation cannot be performed quickly and accurately. Some existing spreader fixers for liver transplantation use mechanical means to open the incision, which is easy to damage the muscles, fat and other tissues of the abdominal wall, and cannot effectively protect the tissues, which is not conducive to postoperative recovery. Moreover, it cannot meet people's needs for free adjustment of multiple angles, and it is not particularly convenient to sterilize.
