Definitions

  • This invention relates to a surgical sealing device for use in arthroplasty surgical procedures and a method of using this device. Background of the invention
  • hip replacement operations a suitable prosthesis is inserted into the canal of the proximal femur. It is common practice during arthroplasty operations to insert a cement (typically polymethylmethacrylate cement) into the femoral canal prior to implantation of the femoral prosthesis. Additionally, it is advantageous to pressurize the cement to improve the interlocking between cement and bone and potentially increase the lifespan of the arthroplasty.
  • a cement typically polymethylmethacrylate cement
  • cement pressurisation is typically achieved by inserting cement with a cement gun, with the flow of cement down the shaft being blocked by a cement restrictor, and back up the shaft by occluding the opening.
  • Various mechanical devices are currently used to occlude this opening. For example, a rectangular or wedge- shaped rubber block may be pushed into the canal opening. Alternatively the surgeon may use one or more sponges or their gloved fingers in an attempt to occlude the canal opening.
  • a drawback of each of these occlusion methods is that the devices do not conform well to the variable shape and size of the femoral canal opening, with the result being an inadequate seal, leakage of cement and inadequate pressurization.
  • a surgical sealing device for use in achieving an occlusive seal inside an opening to a bone canal during arthroplasty surgical procedures, said sealing device including:
  • a flexible inflatable member surrounding a central cavity through which cement may be inserted into said bone canal; and - inflation means to enable said inflatable member to be inflated; wherein in use, said flexible member when inflated conforms to the shape of the bone cavity into which it is inserted thereby forming an occlusive seal.
  • said inflatable member is an annular member or a toroidal member.
  • said inflation means comprises a tube through which a suitable substance can be passed to inflate or deflate said inflatable member, and a valve which in the open position allows said inflatable member to be inflated or deflated and which in the closed position prevents the escape of said suitable substance from the inflatable member when inflated.
  • said suitable substance is either sterile saline or air.
  • said sealing device further includes a compressible auxiliary sealing member attached to the outer rim of said inflatable member, said auxiliary sealing member designed to improve contact with the inner wall of said bone cavity providing an improved occlusive seal.
  • said sealing device further includes a tube attached to an inner portion of said inflatable member to enable the removal of excess blood or other fluid from said bone cavity during cement pressurization.
  • a sealing device including a flexible inflatable member surrounding a central cavity and an inflation means to enable inflation of said inflatable member, wherein said method includes the steps of:
  • the occlusive seal provided by said sealing device prevents the reflux of cement - injecting cement into said bone canal using said cement appHcator gun wherein from said bone canal allowing cement pressurisation;
  • inflation of said inflatable annular member is achieved using a syringe attached to said inflation means, wherein the syringe is filled with either sterile saline or air.
  • said flexible inflatable member is constructed from pliable rubber.
  • the flexible inflatable member of the present invention may be constructed in any suitable size depending on the specific purpose for which it is intended.

  • Fig. 2 illustrates a surgical sealing device according to a further emDodiment of the present invention
  • Figs. 3 to 5 outline the steps of a method of use of the surgical sealing means of Fig. 1 in an arthroplasty operation according to the present invention.
  • the surgical sealing device of the present invention is designed for use in arthroplasty, or joint replacement operations, where cement is injected into the medullary canal of a bone prior to implantation of a prosthesis and pressurization of this cement is desired. Specifically the sealing device is most applicable to hip or shoulder arthroplasty surgical procedures.
  • the sealing device of the present invention provides an occlusive seal inside the opening of the bone canaL such as the opening of the proximal femoral canal, and enables cement to be suitably pressurized without leakage or reflux of cement.
  • Fig. 1 depicts a surgical sealing device 10 according to one particular embodiment of the present invention.
  • the sealing device 10 includes a donut-shaped or toroidal inflatable chamber 12 surrounding a central cavity 14.
  • the cavity 14 is designed to be of suitable size to allow the nozzle of a cement appHcator gun to be inserted therethrough.
  • the inflatable chamber 12 includes inflation means in the form of a tube 16. One end of the tube is located inside the chamber 12 and the other end outside the chamber has a valve 18 attached.
  • the valve 18 and tube 16 enable the chamber 12 to be inflated for use and deflated after use.
  • a syringe filled with either a sterile saline solution or air may be appHed to the outer end of the tube 16, the injection of the sterile saline or air causing the chamber to be inflated.
  • Varying amounts of sterile saline or air may be injected into the chamber 12 depending upon the size to which the chamber is required to be inflated in order to achieve an occlusive seal.
  • the sealing device 10 should be flexible such that when the inflatable chamber is inflated the chamber firmly contacts the inner wall of the bone cavity into which it is inserted thereby forming an occlusive seal.
  • the chamber 12 is constructed of rubber or any other suitably pfiable and flexible material to enable the chamber 12, upon inflation via the inflation means, to conform to the particular shape of the bone into which it is inserted, with further inflation attowing it to push tightly on the inner watt of the bone canal opening, and thus form a tight occlusive seal.
  • sealing device 10 may be constructed in any suitable size depending upon the particular appHcation for which it is designed. For example it is likely that various sizes of sealing device will be required for use in patients of different sizes and for different arthroplasty procedures, such as hip or shoulder arthroplasty.
  • Fig. 2 shows the surgical sealing device of Fig. 1 with various modifications made thereto.
  • the outer rim of the inflatable chamber 12 may be fitted with a compressible material, such as foam or sponge, to serve as an auxiliary sealing member 20 designed to improve the contact between the sealing device and the inner waU of the bone and thereby improve the occlusive seal.
  • a tube 22 may be connected to the inner rim of the inflatable chamber 12 as shdwn in Fig 2. One end of this tube may extend below the lower surface of the sealing device and allow for the removal of excess blood or other fluid from the bone canal during cement pressurization.
  • the tube 22 need not be attached directly to the inflatable chamber 12 but rather may be inserted into the cavity 14 of the sealing device along with the nozzle of the cement appHcator gun.
  • the sealing device 10 may include either the gripping means 20 or the tube 22 as shown in Fig. 2, or may include both of these features.

  • the valve of ihe inflation means (18 in Fig. 1) is closed to prevent deflation of the chamber.

Abstract

L'invention concerne un dispositif chirurgical formé d'un joint occlusif (10) gonflable flexible en forme d'anneau pour canal osseux, utilisé dans la pressurisation du ciment au cours d'une arthroplastie de l'épaule ou de la hanche. Une buse de canon à ciment est placée dans un trou (14) au centre du dispositif (Fig.5), et le dispositif est alors placé dans l'ouverture d'un canal osseux (Fig.6), puis gonflé à l'aide d'un tube (18) pour boucher l'ouverture et former un joint étanche. Lorsque le ciment est injecté à l'aide du canon à ciment, le joint occlusif étanche du dispositif empêche toute fuite de ciment et permet ainsi la pressurisation du ciment injecté dans le canal osseux (Fig.6). Un tube (22) permet de drainer tout excès de sang. Le dispositif est dégonflé à l'aide du tube (18) puis retiré, laissant le canal osseux rempli de ciment et prêt pour l'implantation de la prothèse.
