Description
Technical field
The present invention relates to medical instruments field, it is specifically for use under MRI environment in mammary gland intervention operation.
Background technique
Currently, the posture of prostrate is usually used in patient, and then will lead in the mammary gland intervention operation under MRI environment
Breast tissue simultaneously because breast tissue itself is more liquid, easily shifts, it will cause in state is naturally drooped
When operation accurate surgical procedure can not be completed to the lesion in breast tissue.Therefore, it is necessary to design a kind of for fixed cream
The device of glandular tissue, in order to limit the mobility of breast tissue, assisted biopsy operation is executed, and guarantees the accurate of biopsy sampling
Property, to improve the working efficiency of mammary gland intervention operation.Design for fixed breast tissue device has disclosed in part specially
Benefit, but the device designed at present remains still unsolved problem, for example, Authorization Notice No. is the reality of 204337045 U of CN
A kind of breast fixer is disclosed with new patent, which includes upper fixed ring, intermediate ring and lower fixed ring, wherein
Multiple connecting rods are set between upper fixed ring and lower fixed ring, and connecting rod is made of the multiple groups stub that stretches, setting on the inside of intermediate ring
Lantern ring, lantern ring and connecting rod are corresponding, although the patent can be adjusted according to patient's mammary gland size, adjustable extent compared with
Small, cumbersome, fixed device quickly can not be adjusted and be locked, and in addition distance is excessive between each ring, can not be to breast tissue
Realize the comprehensive fixation of apery hand mode.
There are also the patents of invention that Authorization Notice No. is 105726137 B of CN to disclose one kind for the fixed device of similar mammary gland
The mammary gland intervention operation fixing organization device that can be used under nuclear-magnetism environment, biopsy needle can pass through hollow out grid and complete pair when operation
The puncture of tissue, but the fixing organization apparatus structure is cumbersome need to define one baffle, second level baffle, three-level baffle, corresponding
Multiple components such as the positioning slide plate and driving lead screw of three ranks increase entirety although ensure that comprehensive fixation
The weight and complexity of device, while the position adjusting mechanism movement speed of lead screw driving is slow, noise is larger and operation is numerous
It is trivial, increase unnecessary negative effect factor in surgical environments.In addition, the hollow out grid in the invention is rigid structure, no
It is easily-deformable, and can not be adjusted according to doctor's specific requirements so that operation can operating space reduce, doctor can only be according to
There is fixed gap customization operation plan, and then increases the operation difficulty of doctor, while the hardness of rigid also reduces
The level of comfort of patient；Described in summary, the present invention to solve the above problems, devises a kind of imitative pressure-bearing type palm
Encircling type mammary gland fixes device.
Device fixed for encircling type also discloses partial monopoly, for example, Authorization Notice No. is 105798855 B of CN
Patent of invention disclose a kind of encircling type wheel group fixed mechanism, referred in the invention encircle mechanism include hold-fast body and
Clamping mechanism is used for fixing vehicle wheel, but this is encircled mechanism and mainly utilizes the power clamping arm of setting symmetrical above and below hinged, hingedly connects
The mechanism for connecing mode is excessively heavy, can not provide operation needed for operating space, and metal rigidity material reduce it is fixed
Flexibility adjust it can not flexibly and encircle space, and in addition design symmetrical above and below can only be fixed in one direction, can not
Realize comprehensive fixation and clamping, therefore the encircling type fixed mechanism is not suitable for breast tissue.
The fixed device of the existing mammary gland of comprehensive analysis and the fixed device of encircling type, it is ineffective that discovery remains fixed form
Living, the problems such as device is cumbersome, structure is complicated, heavy and surgical procedure narrow space, and have and set using metal material
The mechanism of meter is to may not apply under nuclear-magnetism environment, therefore the encircling type breast tissue designed under a kind of environment for nuclear-magnetism is fixed
Device is very necessary.
Summary of the invention
In view of the above-mentioned problems, the technical problem to be solved in the present invention is to provide the encircling type creams under a kind of environment for nuclear-magnetism
Glandular tissue fixes device.
The fixed device of encircling type breast tissue under a kind of environment for nuclear-magnetism of the invention, it includes finger plate mechanism,
It is characterized in that：The fixed device of the encircling type breast tissue is made of four identical finger plate mechanisms, four hands

The locking of plate mechanism position；Joint cover is mounted on prostrate bracket by bolt, and joint cover is mutually perpendicular to connecting shaft；Each arc
Shape finger is made of the fixed flexible link of five arcs, and there are five connecting holes in the fixed flexible link of each arc convenient for connecting with three
Axis is connected, and three connecting shafts pass through three connecting holes in arc finger, limits the fixed flexible link of arc along connecting shaft axis
The freedom degree of line rotation and the freedom degree moved radially along connecting shaft, so that arc finger can only be along the axis direction of connecting shaft
Lower slider, meanwhile, the fixed flexible link of five arcs is distributed along the axial direction of connecting shaft, can be adjusted according to doctor's demand each
Arc fixes flexible link, provides flexible, effective operative space using the gap between the fixed flexible link of each arc for doctor,
Basis is provided for further breast tissue operative treatment.
Preferably, the fixed flexible link of the arc is solid soft rubber material, other all part materials are all made of
Highstrenghtpiston, the fixed flexible link of each of arc finger arc can be moved along the axis direction of connecting shaft, if
Determine the fixed flexible link of five arcs in arc finger to be in close contact two-by-two and do not have when gap to be initial position, arc is solid at this time
Determining the moveable maximum displacement of flexible link is 71mm, and then the adjustable gap range for forming arc finger is 0mm to 71mm；Four
The range of round diameter and fixed breast tissue that identical finger plate mechanism is surrounded is 75mm to 160mm.
Preferably, the joint cover is fixed on prostrate bracket, entire finger plate mechanism is nested in the cunning of joint cover
In road, operation consent is being carried out, is pushing finger plate mechanism to move in slideway by doctor, so that arc finger is to breast tissue center
It collapses, after finger plate mechanism reaches ideal position, doctor stops the movement pushing forward, at this point, being mounted on joint cover
Limit tooth engagement in elastic check pin and support plate, fix the position of finger plate mechanism and realize it is self-locking, to reach steady
Determine the purpose of patient's breast tissue, prepares for next aspiration biopsy operation；After the completion of performing the operation, elasticity is released by doctor
Then the self-locking of check pin reversely pulls finger plate mechanism, discharge breast tissue, releases the pact to patient's breast tissue
Beam.
