Problems solved by technology

[0003] At present, arthroscopic microfracture surgery is mainly done through microfracture cones. The microfracture cones are roughly linear. Due to the limitation of the surgical site and angle, the cartilage damage in some areas is difficult and difficult to operate when using microfracture cones.
Especially for the cartilage injury of the patella, because the patella has no additional bony structure support, it is difficult to exert force and stabilize the patella when using the microfracture cone, and it is impossible to accurately locate the perforation position

Abstract

The invention discloses a patella microfracture surgery device. The patella microfracture surgery device comprises a first connecting rod, a second connecting rod and a hole puncher, wherein one end of the first connecting rod is provided with a first handle, the other end of the first connecting rod is provided with a patella bearing device attached to the upper part and / or side part of the patella, the second connecting rod is hinged to the first connecting rod, one end of the second connecting rod is provided with a second handle corresponding to the first handle, the hole puncher is arranged at the other end of the second connecting rod and comprises a hole driller and a spherical housing, the spherical housing is internally provided with a hole driller channel, and the hole driller channel is provided with an opening facing the patella bearing device and used for at least part of hole driller exposed and a punching drive mechanism for driving at least part of hole driller to be exposed out of the opening. The patella microfracture surgery device can stably and reliably fix the patella, can conveniently adjust the punching position and punching depth, can conduct microfracturepunching operation at any position of the cartilage face of the patella, is simple in operation and can avoid iatrogenic injury to the normal cartilage.

Description

technical field [0001] The invention relates to the field of orthopedic surgical instruments, in particular to a patella microfracture surgical device. Background technique [0002] Microfracture surgery, that is, by drilling holes in the damaged cartilage (generally, the diameter of the holes is 2-3mm, the hole spacing is 3-4mm, and the depth is 5-8mm), so that a part of the bone marrow and blood will seep out of the holes to form blood clots . This blood clot contains stem cells from which they can differentiate to form repairing fibrocartilage-like tissue that takes the place of cartilage. [0003] At present, arthroscopic microfracture surgery is mainly done through microfracture cones. The microfracture cones are roughly linear. Due to the limitation of the surgical site and angle, the cartilage damage in some areas is difficult and difficult to operate when using microfracture cones. . Especially for the cartilage injury of the patella, because the patella has no ad...
