Definitions

  • the utility model relates to the technical field of medical appliances, in particular to a rigid support for operating and positioning surgical tools during surgery.
  • the stents used by doctors are generally made of plastic, mainly considering the relative convenience of plastic molding.
  • plastic stents there are also many problems with the use of plastic stents.
  • the doctor can only visually observe whether the placement of the plastic stent is appropriate. The process is time-consuming and affects the progress of the operation.
  • the mechanical strength of plastic is poor, and it is easy to deform after being stressed.
  • friction between the saw and the plastic bracket generates high temperature, and the plastic will melt and deform at high temperature. It is difficult to ensure the effect of the surgical design and affect the accuracy of the operation, and even affect the success rate of the operation and take a long time, thereby increasing the physical and mental load of the doctor and the patient.
  • the present invention provides a rigid stent for surgery.
  • it can avoid the deformation of the rigid stent caused by operating the surgical tool during the operation, which ensures the accuracy of the operation.
  • Assisted body scanning equipment to locate and observe the stent, so that the surgeon can accurately confirm the placement of the rigid stent during the operation, and can also improve the accuracy of the operation.
  • the rigid support for surgery is provided with at least a fitting surface that is adapted to the surgical part and a positioning device for operating and positioning the surgical tool.
  • the fitting surface of the rigid support is attached to and fixed to the surgical part.
  • the operating part is limited to the positioning device.
  • the positioning device is a saw blade slot, which includes a slot wall for defining both sides of the saw blade and a saw blade slot penetrating the entire rigid support.
  • a locking groove for fixing the rigid bracket to the surgical site, and a screw or a positioning needle passes through the locking groove and is connected and fixed with the surgical site.
  • a locking groove for fixing the rigid bracket to the surgical site is also provided, and a screw or a positioning pin passes through the locking groove and is connected and fixed with the surgical site, and the locking groove is provided on the outside of at least one groove wall of the saw blade groove.
  • an auxiliary positioning surface is also provided, which is connected to the bonding surface and is staggered.
  • the rigid support is made of metal or ceramic.
  • a plurality of hollows are provided from the rigid support to the bonding surface.
  • the rigid bracket is provided with a plurality of hollows to form a grid shape to the bonding surface.
  • the use of a rigid stent because it is made of materials with good mechanical properties, can prevent the rigid stent from being deformed due to the operation of surgical tools during the operation, and ensure the accuracy of the operation.
  • the rigid bracket is also designed with a fitting surface that fits the surgical part, which makes the installation of the rigid bracket more accurate and further improves the accuracy.
  • the entire rigid support is clearly visible under X-rays, which allows the surgeon to confirm the placement position of the surgical metal support frame during the operation, and can also improve the accuracy of the operation.
  • a rigid support for surgery is provided with at least a bonding surface 1 that is in conformity with a surgical part and a positioning device for operating and positioning a surgical tool. 1 It is attached and fixed to the surgical part, and the operating part of the surgical tool is limited to the positioning device.
  • the use of a rigid stent because it is made of materials with good mechanical properties, can prevent the rigid stent from being deformed due to the operation of surgical tools during the operation, and ensure the accuracy of the operation.
  • the rigid support is also designed with a fitting surface 1 that fits the surgical part, which makes the installation of the rigid support more accurate and further improves the accuracy.
  • the entire rigid support is clearly visible under X-rays, which allows the surgeon to confirm the placement position of the surgical metal support frame during the operation, and can also improve the accuracy of the operation.
  • the positioning device is a saw blade slot 2, which includes a slot wall for limiting the sides of the saw blade and a saw that penetrates the entire rigid support. Slot 2.
  • the surgical tools used in surgical operations are generally orthopedic saws. In order to match the use of orthopedic saws, on the one hand, the operating direction of the orthopedic saw is controlled.
  • the groove walls on both sides of the saw slot 2 pass through the sides of the saw blade, including Operating direction and operating range, etc., to ensure the accuracy of the operation; on the other hand, the degree of operation of the orthopedic saw is controlled, and the depth of operation is limited when the handle of the saw is in contact with the upper surface of the saw groove 2 to prevent operation Sometimes hurt ligaments or nerve lines.
  • the doctor Before performing orthopedic surgery, the doctor first needs to fix the positioning device at the corresponding surgical site.
  • the positioning device is locked by screws or positioning pins.
  • the rigid bracket also has a locking groove for fixing the positioning device to the surgical site.
  • the locking groove 3 can also limit the depth of insertion of the screw through the positioning pin during fixing, and prevent injury to the ligaments or nerve wires during operation.
  • the locking grooves 3 can be provided on the outside of the same groove wall of the saw blade groove 2 or respectively on both sides of the saw blade groove 2 according to the needs of use.
  • an auxiliary positioning surface is also provided, which is connected to the fitting surface 1 and Staggered settings, the auxiliary positioning surface also fits with the surgical site but is basically on a different plane from the bonding surface 1.
  • an auxiliary positioning surface can be provided, and the auxiliary positioning surface is in contact with the side of the radius, so that the rigid stent can quickly and accurately locate and fix the radius surgery site.
  • the rigid support is made of metal or ceramic, which has sufficient strength as a fixture for cutting operation and is not easy to deform, and it is not deformed even when the cutting produces high temperature during the operation.
  • the density of the above materials is high, and the rigid support can be clearly displayed under X-ray during surgery, which is convenient for doctors to observe and judge.
  • the production can be made by 3D printing. Before surgery, the operation site is determined by X-ray or nuclear magnetic resonance scanning and the bone contour parameters of the operation site are obtained. Based on these parameters, a 3D model of the rigid scaffold is established, and then the rigidity is directly completed by a 3D printer.
  • the manufacture of the stent can ensure that the fitting surface 1 and the auxiliary positioning surface can fully fit with the bones of the surgical site and ensure the accuracy of the surgery.
  • the rigid support is provided with multiple cutouts to the fitting surface 1 and can even form a grid shape, so that the doctor can observe whether the rigid support fits the bone surface of the surgical site sufficiently through the cutout.
