Abstract
The invention discloses a kind of cranium brain deep operation clear tubular retractors, the interior sheath including operation sheath and cooperation in operation sheath, and the front end of the operation sheath and interior sheath is set as cone point, sheath of performing the operation and the interior equal oval in shape of sheath tube section.The perform the operation front end of sheath of the present invention is unique conical design, and sharper, when sheath protrudes into brain tissue deep, conical design pushes sheath gradually to open brain tissue, and wound is small, and intervention is more convenient；Sheath of performing the operation is the cylinder of ellipse（With cylindrical sheath ratio）, the space in major diameter direction and angle are larger, in this way in the limited surgical procedure space of tubulose, convenient double instruments pass in and out simultaneously, facilitate operation, more preferable to major diameter both ends steering property, smaller to brain tissue distraction force, the surgical procedure space of medical staff becomes larger, and is conducive to observation and operation；In addition, devising the handle of grasping in sheath tail end, grasped by the way that operation sheath handle is more convenient.
Description
Technical field
The present invention relates to field of surgical, specifically a kind of cranium brain deep operation clear tubular retractor.
Background technique
The important directions that operations on cranium and brain has been Microinvasive neurosurgery development are carried out under nerve endoscope, the core of this technology is
The wound of previous operative approach is further reduced, appearing for lesion is expanded, increases the chance of intuitive excision lesion.
Endoscopic surgery can be divided mainly into sheath outer operation and intrathecal operation.Sheath outer operation mainly utilizes human body natural's
Physiology lacuna carries out skull base surgery.Typical sheath outer operation is exactly intranasal surgery of skull base, using the natural channel of nasal cavity, is mentioned
Appear wild for a more spacious operation, bigger work angle can also be provided, and nerve endoscope can be goed deep into hand
In art area, short distance observation operative region anatomical structure, make it is past " stand outside the door see house become enter see room within doors
Son ".By the observation nearby to anatomical structure, so that tumor resection more safety can be substantially reduced complication with thoroughly,
It may also reach up a preferable cosmetic result simultaneously, due to not needing to expand nasal cavity, this operation using nasal speculum
The wound of operation is small, and patient is postoperative more comfortable, and post-operative recovery is fast, is qualified Minimally Invasive Surgery.
Existing cranium brain deep operation retractor, has the following disadvantages：1）The front end for sheath of performing the operation is not sharp enough,
Wound is big, and intervention is inconvenient；2）Operation sheath is inconvenient to operate, and steering property is bad, does not reach requirement to skin histology distraction force,
The surgical procedure space of medical staff is small, is unfavorable for observing and operate；3）Inconvenience grasps operation sheath, operation difficulty
Greatly.Therefore, for the above status, there is an urgent need to develop a kind of cranium brain deep operation clear tubular retractors, current to overcome
Deficiency in practical application.
Summary of the invention
The purpose of the present invention is to provide a kind of cranium brain deep operation clear tubular retractors, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the present invention provides the following technical solutions：
A kind of cranium brain deep operation clear tubular retractor is set to the interior sheath in operation sheath including operation sheath and cooperation
The front end of pipe, the operation sheath and interior sheath is set as cone point, sheath of performing the operation and the interior equal oval in shape of sheath tube section.
As a further solution of the present invention：The operation sheath and interior sheath are made of plastics or metal, sheath of performing the operation
Pipe and the wall thickness of interior sheath are less than 1mm.
As a further solution of the present invention：It is equipped with protection sheath ontology on the outside of the operation sheath, protects sheath
First through hole and the second through-hole are offered on ontology respectively, is additionally provided with indicating graduation on the protection sheath ontology.
As a further solution of the present invention：The first through hole is rounded, and the second through-hole is in both ends arc square outstanding
Shape.
As a further solution of the present invention：The protection sheath ontology and the tail end for sheath of performing the operation are respectively arranged with protection sheath
Ontology aileron and operation sheath aileron, protection sheath ontology aileron is identical with the operation geomery of sheath aileron, protects
Protection sheath ontology handle and operation sheath handle are separately installed on the outside of shield sheath ontology aileron and operation sheath aileron.
As a further solution of the present invention：Being additionally provided on the right side of the protection sheath ontology handle can be to operation sheath
The block board of handle detent is additionally provided with the ingot bolt for being locked to operation sheath handle on block board.
As a further solution of the present invention：When the operation sheath handle is close to protection sheath ontology handle, sheath is protected
Ontology aileron and the close connection simultaneously of operation sheath aileron, and ingot bolt can be locked to operation sheath handle.
As a further solution of the present invention：The protection sheath ontology handle and protection sheath ontology junction are additionally provided with reinforcement
Muscle.
Compared with prior art, the beneficial effects of the invention are as follows：The front end for sheath of performing the operation is unique conical design, more cutting edge of a knife or a sword
Benefit, when sheath protrudes into brain tissue deep, conical design pushes sheath gradually to open brain tissue, and wound is small, and intervention is more convenient；Hand
Art sheath is the cylinder of ellipse（With cylindrical sheath ratio）, the space in major diameter direction and angle are larger, in this way in pipe
In the limited surgical procedure space of shape, convenient double instruments pass in and out simultaneously, facilitate operation, more preferable to major diameter both ends steering property, to brain
Organize distraction force smaller, the surgical procedure space of medical staff becomes larger, and is conducive to observation and operation；In addition, being designed in sheath tail end
The handle grasped, passes through that operation sheath handle is more convenient to be grasped.
