Description
Technical field
The utility model belongs to technical field of medical instruments, specially a kind of brain retractor.
Background technology
Brain retractor extensive use in neurosurgery operation of opening cranium, especially brain deep operation, neurosurgeon are past
Brain retractor is applied toward conventional.Traditional brain retractor is typically hard steel or other metal alloy bands, it is with abrupt change or
The edge and finite surface area of sharp outline.Be introduced into these retractors during performing the operation in brain tissue, then firmly drawing with
Separating or raise brain tissue is easy to operation to carry out.But brain tissue is very soft very fine, especially in brain damage, ischemic or encephaledema
In the case of, brain retractor both may directly oppress cause local brain tissue and dampen, and can also cause local brain tissue under brain spatula to lack
Blood, it may occur that the complication of " retracting damage ", brain spatula movement causes operating field to reduce or expand and influence operation or aggravate brain
The situation of tissue retraction damage, operating theater instruments is likely to brush up against brain tissue and causes damage in operation in addition.Often, it is refreshing
Exposure is taken far more than the strategy for the brain tissue being required or desirable for through surgeon, so that sufficiently large operative region is opened,
And this greatly differs from each other with minimally invasive theory.
Utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is that it is that surgery is micro- to design offer a kind of
The technical scheme of brain retractor used in invasive procedures, its is simple in construction, using conveniently, safely.
Described a kind of brain retractor, it is characterised in that including expansion pipe, sleeve pipe；Described expansion pipe, sleeve pipe are equal
For the siphunculus of both ends open, expansion pipe, the cross section of sleeve pipe are ellipsoidal structure, and expansion pipe, the longitudinal section of sleeve pipe are down
The trapezium structure put；Expand pipe top edge to set along side, cannula tip edge is correspondingly arranged on pressing rib, sleeve side walls and set
Put one longitudinally through crack；Expand pipe outer tube diameter and be more than casing pipe internal diameter, pipe is expanded when using and promotes sleeve bottom
The crack of sleeve side walls is strutted.
Described a kind of brain retractor, it is characterised in that the gap in crack is 0.5-3mm.
Described a kind of brain retractor, it is characterised in that the apparatus that is equipped with along on the outside of side of expansion pipe fixes hand
Handle.
Described a kind of brain retractor, it is characterised in that two pressing hands are symmetrical arranged on the outside of the pressing rib of sleeve pipe
Handle.
Described a kind of brain retractor, it is characterised in that described expansion pipe, sleeve pipe are made of transparent plastic.
A kind of above-mentioned brain retractor, is made up of, its is simple in construction, compact, it is easy to load and unload, and is easy to expansion pipe, sleeve pipe
The operation technique of doctor, using safe and reliable, it is adaptable to brain Minimally Invasive Surgery.

Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As illustrated, the brain retractor, including expansion pipe 1, sleeve pipe 2；Described expansion pipe 1, sleeve pipe 2 are two ends
The siphunculus of opening, expansion pipe 1, the cross section of sleeve pipe 2 are ellipsoidal structure, and expansion pipe 1, the longitudinal section of sleeve pipe 2 are to be inverted
Trapezium structure；Expand the top edge of pipe 1 to set along side 101, the top edge of sleeve pipe 2 is correspondingly arranged pressing rib 201, sleeve pipe 2
On the wall of side set one longitudinally through crack 203；Expand the outer tube diameter of pipe 1 and be more than the internal diameter of tube body of sleeve pipe 2, pipe is expanded when using
The 1 propulsion bottom of sleeve pipe 2 struts the crack 203 of the side wall of sleeve pipe 2.The gap in crack 203 is 0.5-3mm.Expand pipe 1 along side
101 outsides are equipped with apparatus fixed handle 102.The outside of pressing rib 201 of sleeve pipe 2 is symmetrical arranged two pressing handles 202,
In use, both hands pin position needed for sleeve pipe 2 is pushed into operation by pressing handle 202.Described expansion pipe 1, sleeve pipe 2 are using saturating
Bright plastics are made.What expansion pipe 1 top edge was set presses expansion pipe 1 when being used to promote along side 101, promote expansion pipe 1 to enter
The lower end of sleeve pipe 2.
The pressing rib 201 that the top of sleeve pipe 2 is set, can coat the tissue of surrounding, prevent surrounding tissue in surgical procedure
Damaged by operating theater instruments；Expansion pipe 1 is promoted when being pushed completely into the lower end of sleeve pipe 2, expansion pipe 1 along side 101 and pressing rib 201
Gear connects cooperation.
Occupation mode of the utility model in surgical procedure：Otch is formed in delicate tissues, by sleeve pipe 2 along fine
Tissue is slowly advanced to operative site, and then the inner side expansion pipe 1 along sleeve pipe 2 is advanced to the lower end of sleeve pipe 2 by crack 203
Support is big, and operation path is formed, and operating theater instruments enters Minimally Invasive Surgery of entering a profession from the inner side of expansion pipe 1.
Advantage of the present utility model is as described below：
1. it is ellipsoidal structure to expand pipe 1, the cross section of sleeve pipe 2, expansion pipe 1, the longitudinal section of sleeve pipe 2 are to be inverted
Trapezium structure so that sleeve pipe 2 can be advanced to operative site along physiology crack, reduce the damage to delicate tissues；In hand
When art apparatus enters internal rows delicate procedure, the possibility that operating theater instruments grazing delicate tissues cause damage is eliminated, it is to avoid
Retract damage；Sleeve pipe 2 has a series of specification that sizes are not waited, and can select different sizes as required before surgery to reach
Minimally invasive purpose.
2. the lower end that inner side of the expansion pipe 1 along sleeve pipe 2 is advanced to sleeve pipe 2 supports in crack 203 greatly, the operation expanded
The visual field and operating space.
3. expansion pipe 1, sleeve pipe 2 are made of transparent plastic, the outside of sleeve pipe 2 can be observed in surgical procedure at any time
Delicate tissues whether there is bleeding etc., improve operation safety.
Better embodiment of the present utility model is the foregoing is only, protection domain of the present utility model is not with above-mentioned reality
The mode of applying is limited, as long as the equivalent modification or change that those skilled in the art are made according to the utility model disclosure,
The protection domain all recorded without departing from the utility model.
