Description

Skull flap preservation sterilization equipment

Technical Field

The utility model relates to the technical field of external preservation of skull flap, in particular to skull flap preservation and sterilization equipment.

Background

In neurosurgery diseases, the brain fracture, cerebral edema, intracranial hematoma and the like are needed to open the cranium in time for decompression, and partial patients need to perform bone flap decompression. The skull defect caused by the bone flap decompression operation damages the physiological integrity of the cranial cavity and the consistency of the cranial cavity volume is lost. Can cause the symptoms of skull defect syndrome. In addition, the skull defect can affect the recovery of the patient's post-operative neurological function. The skull repair not only can restore the physiological integrity of the cranial cavity and prevent the brain tissue from being damaged again, but also can promote the restoration of the nerve function in early skull repair. The materials for skull repair include artificial materials and autologous materials. The titanium mesh has better biocompatibility and is widely applied at present. However, artificial materials are put into the body, which can cause immunological rejection reactions and psychological burden to different degrees.

Compared with the artificial materials, the autologous skull has the advantages that: the self skull maintains the original skull structure and shape, has good anastomosis with skull defect, and can maintain good appearance after operation; has good tissue compatibility, little rejection reaction of human body, little occurrence of subcutaneous effusion, quick postoperative recovery, easy psychological acceptance of patients with few complications and reduced psychological rejection.

There are various methods for preserving bone flap, and there are methods for embedding under scalp, abdominal wall and thigh skin, and although these methods do not produce bone flap necrosis in a short time, the time exceeds 3 months, the bone flap is reduced and thinned to different extent, thereby causing poor anastomosis with skull defect, and affecting the stability after operation. In addition, an incision is additionally made on the abdomen or thigh and other parts of the patient, and an operation wound is added to the patient; and the bone flap is buried after operation, so that discomfort can be generated, and a certain mental burden is caused to the patient.

The application number is: CN202020695831.6, publication number: the utility model patent of CN212497164U (hereinafter referred to as 'prior art 1') discloses a skull bone flap activity preservation box for neurosurgery, which comprises a box body, wherein a preservation chamber is arranged in the box body, a through hole is further formed in the lower part of the left side wall of the box body, a sliding mechanism is further arranged on the inner side of the left side wall of the box body, the sliding mechanism comprises a sliding rail, a fixed plate and a guide sliding block, wherein the sliding rail and the fixed plate are symmetrically distributed on the left side wall of the box body, the guide sliding block is symmetrically arranged on the fixed plate, the sliding mechanism further comprises a rack, a gear and a motor connected with the gear, the rack and the gear are in meshed transmission and are symmetrically distributed, a bearing plate is further arranged above the fixed plate through an adjusting device, a color detection sensor is further arranged at the position of the through hole, and a supporting seat and a sterile box fixedly arranged at the upper end of the supporting seat are further arranged on the lower part of the right side of the preservation chamber.

The specification of the prior art 1 discloses a skull bone flap activity preservation box for neurosurgery, which performs irradiation sterilization treatment on the skull flap on a bearing plate by a gamma ray irradiation sterilizer and uses an electric telescopic rod to push the bone flap into a box for preservation; however, in practical application, firstly, the mechanical element cannot be guaranteed to be completely sterile, the skull bone flap is placed in the storage box, bacteria and dust cannot be grown in the storage box, and the safe preservation method of the skull bone flap is to use physiological saline for washing and then preserve the skull bone flap in a sealed bag filled with preservation solution prepared by mixing distilled water and glycerol, so that the skull bone flap cannot be preserved in a sterile environment in the prior art;

moreover, the sterilization of the skull flap in prior art 1 is not complete, and when the skull flap is placed on the carrier plate, the gamma radiation sterilizer cannot sterilize the skull flap adjacent to the side of the carrier plate, even if the gamma radiation sterilizer has very strong penetrability, the skull flap adjacent to the side of the carrier plate is very little sterilized, which results in incomplete sterilization of the skull flap, and thus the stored skull flap cannot be used.
