Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of soft tissue punching knife 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 new minimally invasive cutting soft tissue punching knife group.
Invention content
In view of this, the present invention provides a kind of soft tissue punching knife group, cutting of the present invention in punching knife and punching broach shell
On sword, continuous sharp edge is good to cotton-shaped soft tissue effect, cutting surface is more neat by being arranged, and multiple tooth sword is then conducive to excision
When prevent soft tissue from slipping.
The technical scheme is that：A kind of soft tissue punching knife group, including punching broach shell and punching knife, the punching knife
It is sheathed on inside the punching broach shell, which is characterized in that the punching knife can realize relative displacement inside punching broach shell；It is described
It is punched broach shell side and is equipped with cutting window, the end of the punching knife is equipped with knife-tooth structure, and the knife-tooth structure is by uniformly arranging
It is formed in the cutter tooth portion of punching knife end.
Further, the cutter tooth portion is any one of rake tooth, stepped tooth, helical teeth, offset teeth structure.In punching knife
On the cutting edge of punching broach shell, continuous sharp edge is good to cotton-shaped soft tissue effect, cutting surface is more neat by being arranged, more
The sword of tooth is then conducive to prevent soft tissue from slipping when excision.
Further, the A angular regions of the cutting edge of the punching knife are 0-65 °.Particularly, the angles A of the cutting edge are
Refer to the angle formed on the outside of the cutter tooth portion of punching knife and inside punching broach shell.
Further, the punching knife is the tubular structure that tubulose or side are equipped with horizontal end face.
Further, the punching knife is hollow structure.
Further, the cutting window is perforation semicircle cutting window, arc line shaped cuts window, rectangle cuts window,
Tear drop shape cuts any one of window structure.
Further, the cutter tooth portion is continuous cutting edge.
The present invention changes original excision mode, makes excision process closer to the shear action of scissors, and reduction was performed the operation
That is organized in journey tears phenomenon；So that postoperative position flatness of being cut is more preferable, postoperative complications are reduced, are conducive to Rehabilitation.It is logical
The structure for the cut-off knife that liquidates and the setting at the angles A are crossed, cutter sharpness can be improved, improves the stock-removing efficiency of knife group, reduces cutting force.
