Technical Field

The invention belongs to the technical field of bone harvesting, and particularly relates to a novel bone harvesting method and a novel bone harvesting device.

Background

Currently, the closest prior art: the repair and reconstruction of the large-section bone defect of the four limbs usually needs to take autologous bones for bone grafting, and for patients with large bone defect amount, the autologous bones behind the ilium need to be taken. The traditional method comprises the steps of firstly carrying out prone position, disinfecting and paving, taking bones, binding and fixing the bone taking area after the completion of the operation, changing the position to be a supine position, and then carrying out disinfecting and paving and bone grafting operation on the bone defect position. This art formula need carry out twice disinfection and spread piece of cloth, need change the operation position simultaneously, not only complex operation increases operation, anesthesia time simultaneously, greatly increased patient's anesthesia risk and complication such as operation incision infection.

In addition, what expose the incision when getting the bone adopts is that backbone way of escape braking drag hook, lacks special equipment, because of the ilium district is an inclined plane, so can appear the incision and expose inadequately, influence and get the bone and adopt, the extension is got the bone time, leads to the complication to increase, secondly get the bone at present and take out ilium planking together with cancellous bone, complication such as pain takes place to the postoperative to the ilium can't regenerate.

In summary, the problems of the prior art are as follows:

(1) the change of the operation body position is needed, and the towel is needed to be disinfected and spread twice, so that the operation is complex, the operation and anesthesia time is increased, and the anesthesia risk and the operation complications of the patient are greatly increased.

(2) Inadequate exposure of the bone harvesting area results in prolonged bone harvesting time and increased bleeding.

(3) The form of the ilium cannot be completely kept after the bone is taken, and the pain complications are more.

The difficulty of solving the technical problems is as follows: aiming at the problem (1), some students adopt allogeneic bones or artificial bones as substitute materials, but the bone defects of the two materials after bone grafting have extremely low healing rate and low healing speed, thereby greatly increasing the risk of nonunion of the bones of patients and increasing the incidence rate of medical disputes, so that the current technical proposal except the application has no direct solution, and the current technical proposal aiming at the problems (2) and (3) has no direct solution.

The significance of solving the technical problems is as follows: the technical problem can be successfully solved, the operation steps are greatly reduced, the operation is simple and easy to operate, the operation time is greatly saved, the operation and anesthesia risks of a patient are reduced, the medical cost is saved, the medical expense is reduced, bleeding is reduced, the form of the ilium is kept, and complications such as pain are reduced.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides a novel bone taking method and a novel bone taking device.

The invention is realized in such a way that a novel bone harvesting method comprises the following steps:

first, the patient is in lateral decubitus.

And step two, simultaneously disinfecting and paving the four limbs and the bone taking area, and performing two operations by adopting one body position.

And thirdly, exposing the bone taking area by adopting a novel spreader.

Fourthly, a novel bone taking chisel is adopted to completely chisel the external iliac plate.

Fifthly, scraping cancellous bone by using a curette.

And sixthly, filling the outer plate back after the bone is taken out.

And step seven, suturing the incision and carrying out bone grafting operation.

Another object of the present invention is to provide a novel bone harvesting device, comprising: head, connecting portion and decorative pattern handle.

The head tail end of the novel bone taking device is hollow, the blank between the head and the connecting part is hollow, a bone block embedded into the head is conveniently ejected out, and the side face of the head is solid.

In summary, the advantages and positive effects of the invention are: at present, no related technology exists for bone taking after ilium, the previous operation needs to take bone in prone position first, then the operation is carried out by laying a sterilized towel again in supine position, the operation time is long, the operation is complicated, and more complications exist; the patient takes the lateral position in the method of the invention; meanwhile, the four limbs and the bone taking area are disinfected and paved, and two operations are carried out by adopting one body position; a novel spreader is adopted to expose a bone taking area; the outer plate of the ilium is completely chiseled by adopting a novel bone chisel; scraping cancellous bone by using a curette; filling the outer plate back after the bone is taken out; the incision is sutured and bone grafting is performed. The novel get bone device includes: head, connecting portion and decorative pattern handle. The head tail end of the novel bone taking device is hollow, the blank between the head and the connecting part is hollow, a bone block embedded into the head is conveniently ejected out, and the side face of the head is solid. The invention avoids the complex processes of frequently changing body positions and sterilizing in the operation, and reduces the material cost in the operation; greatly reduces the operation time, reduces the amount of bleeding, and reduces the anesthesia risk and the operation complication of the patient.
