Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of Double Directional Cutting punching knife of soft tissue punching
Group.
Background technology
Joint is because it moves and often bears the characteristic for back and forth loading, impacting etc. and become most vulnerable knot repeatedly
Structure, the patient populations such as cartilage damage, synovitis and meniscus injury sharply increase with the aggravation of aging of population trend, by
Joint tissue to damage needs to be removed or modified by operation.Endoscopic surgery belongs to the scope of Minimally Invasive Surgery, phase
Than in traditional open operation, Minimally Invasive Surgery has many advantages, such as that wound is small, it is fast to restore and few intercurrent disease, and endoscopic surgery is
Received by more and more patients, the demand also sharp increase therewith for for example minimally invasive planing tool of endoscopic surgery tool etc..
Power planing system is the key that the minimally invasive cleaning art cutting instrument of knee arthroscope, can help doctor in a short time
The a large amount of tissue of removal.It is substantially similar in structure design, by power planing handle, host and various types of
Shaping tool forms.Power planing handle can ride or handle control, and connects suction device, by the bone group of planing, polishing
It knits and is taken out of outside joint with soft tissue.
However, the existing minimally invasive high efficiency cutting soft tissue instrument of arthroscope mainly rotates shaping tool, such as planing tool, bistrique
Deng, for cutting effect, that there are cutting outputs is small for minimally invasive rotation planing tool, is easy to happen chip blocking, and cutting end face is irregular etc.
Problem；For structure, minimally invasive rotation planing tool inner and outer pipes be small diameter long shaft member, tube wall is thin and intensity is insufficient, inner tube turn
Without accurate rotational positioning between axis and outer tube, cause inner tube when driving high speed rotation by dynamical system, plays shear action
Inner tube distal end occur larger rotation beat amplitude, thus the cutting tooth on inner tube distal end and distal end can be sent out with distal outer tube
Raw collision, serious influence cutter life, sharpness, cutting stability and safety.
It is then desired to propose a kind of Double Directional Cutting punching knife group of new minimally invasive cutting soft tissue punching.
Invention content
In view of this, the present invention provides a kind of Double Directional Cutting punching knife group of soft tissue punching, the present invention passes through punching
Setting in the structure of knife and punching broach shell makes excision process closer to the shear action of scissors by the way of Double Directional Cutting,
That is organized in reduction surgical procedure tears phenomenon；So that postoperative position flatness of being cut is more preferable, postoperative complications are reduced, are conducive to suffer from
Person's rehabilitation.
The technical scheme is that：A kind of Double Directional Cutting of soft tissue punching is punched knife group, including punching broach shell and
It is punched knife, the punching broach shell is set to inside the punching broach shell, which is characterized in that the punching knife can be inside punching broach shell
Realize relative displacement；The punching broach shell is equipped with the first cutting edge, and the punching knife is equipped with the second cutting edge, first cutting
Sword is double cutting edges；Second cutting edge is double cutting edges.
Further, double cutting edges are any one of perforation semicircle sword, arcuate blade, rectangle sword structure.
Further, the punching knife further includes multi-tool edge knife pipe, and the multi-tool edge knife pipe surface is placed with several
A cutting hole, the cutting hole are circular cut hole or rectangle cutting hole.
Further, the punching broach shell further includes multi-tool edge knife pipe, if the multi-tool edge knife pipe surface is placed with
Dry cutting hole, the cutting hole are circular cut hole or rectangle cutting hole.
Further, the punching knife is the tubular structure that tubulose or side are equipped with horizontal end face, the punching broach shell
Structure and the structure of punching knife are correspondingly arranged.
The Double Directional Cutting that the present invention uses refers to punching knife can occur cutting movement during straight line is past and returns,
Improve stock-removing efficiency.The punching effective cutting edge of knife can only coordinate a plane with the punching broach shell for having plane window.
The present invention makes to cut off by the setting for being punched knife and being punched in the structure of broach shell by the way of Double Directional Cutting
Journey closer to scissors shear action, reduce surgical procedure in organize tear phenomenon；So that postoperative cut position flatness more
It is good, postoperative complications are reduced, Rehabilitation is conducive to.
