Abstract
The utility model provides a biotype femoral head surface substitutive prosthesis, includes single glass and centibar, single glass of internal surface sets firmly the intubate, the intubate is including being equipped with the open -ended cavity, the centibar is the hollow tube compriseed lumen and pipe wall, be equipped with on the pipe wall with the communicating growth through -hole of lumen, the centibar cartridge is equipped with the pinhole and reaches rather than the complex bolt in the cavity of intubate on the pipe wall of intubate. The structure is firm, convenient operation.
Description
Technical field
This utility model relates to a kind of human femur head surface replacement prosthesis, particularly relates to a kind of human hip Biotype femoral head surface substitutive prosthesis.
Background technology
Application number is 201110104347.7, publication No. be CN102188298A patent discloses a kind of Biotype femoral head surface substitutive prosthesis, comprise single glass and center-pole, center-pole is the hollow pipe be made up of tube chamber and tube wall, tube wall is arranged the growth through hole communicated with tube chamber, tube wall is provided with external screw thread, is threaded connection between center-pole and femur.Intubate is provided with, the single glass of tube chamber grafting by intubate and center-pole in single glass.In this technical scheme, because intubate is connected with the tube chamber plug-in mounting of center-pole, if coordinate too tight between intubate and the tube wall of center-pole, difficulty can be brought to operation technique, also can give in the future second operation time removing of replacement prosthesis make troubles, if coordinate tight between intubate and the tube wall of center-pole, easily cause again being moved between intubate and center-pole, the of long duration femoral head replacement prosthese that can cause occurs to loosen, thus shortens the service life of femoral head replacement prosthese.
Utility model content
The purpose of this utility model is the Biotype femoral head surface substitutive prosthesis providing a kind of convenient operation and stable connection.
The purpose of this utility model realizes like this, a kind of Biotype femoral head surface substitutive prosthesis, comprise single glass and center-pole, single glass of inner surface sets firmly intubate, intubate comprises the cavity being provided with opening, center-pole is the hollow pipe be made up of tube chamber and tube wall, and tube wall is provided with the growth through hole communicated with tube chamber; Center-pole is plugged in the cavity of intubate, the latch that the tube wall of intubate is provided with pin-and-hole and is mated.In the technical program, single glass is connected with center-pole plug-in mounting by the intubate set firmly, and by latch to coordinate with pin-and-hole give fastening, stabilized structure, easy to operate.
For the ease of connect, above-mentioned latch with between pin-and-hole for being threaded.
In order to not affect the smooth of cannula outer wall, the length of latch is not more than the thickness of intubate tube wall.
For the ease of installing, the end face of latch is provided with groove, to screw with instruments such as screwdrivers.
In order to ensure the steadiness of structure, the length of intubate is not less than the height of single glass.
For the ease of connecting, the opening part of intubate is provided with interior chamfering.
In order to be convenient to connect further, the link of center-pole and intubate is provided with outer chamfering.
In order to improve the steadiness of structure further, above-mentioned outer chamfering is arc and adaptive with the inner surface of single glass.
This utility model has following beneficial effect:
1, single glass in this utility model is connected with center-pole plug-in mounting by the intubate set firmly, and by latch to coordinate with pin-and-hole give fastening, stabilized structure, easy to operate.
2, this utility model structure is simple, is easy to processing.
Accompanying drawing explanation
Fig. 1 is this utility model example structure schematic diagram.
Fig. 2 is the cannula structures schematic diagram in this utility model embodiment.
In figure, 1. single glass, 2. center-pole, 3. grows through hole, 4. intubate, 5. pin-and-hole, 6. latch.
Detailed description of the invention
Embodiment, a kind of Biotype femoral head surface substitutive prosthesis, see Fig. 1 and Fig. 2, comprises single glass 1 and center-pole 2, single glass of 1 inner surface sets firmly intubate 4, and the length of intubate 4 is slightly larger than the height of single glass 1.Intubate 4 comprises the cavity being provided with opening, and center-pole 2 is the hollow pipe be made up of tube chamber and tube wall, and tube wall is provided with the growth through hole 3 communicated with tube chamber; Center-pole 2 is plugged in the cavity of intubate 4, the latch 6 that the tube wall of intubate 4 is provided with pin-and-hole 5 and is mated.
For being threaded between latch 6 with pin-and-hole 5, latch 6 outer wall is provided with external screw thread, and pin-and-hole 5 inwall is provided with female thread.
The length of latch 6 equals the thickness of intubate 4 tube wall, and the end face of latch 6 is provided with groove.
The opening part of intubate 4 is provided with interior chamfering, and center-pole 2 is provided with outer chamfering with the link of intubate 4, and outer chamfering is arc and adaptive with the inner surface of single glass 1.
