Description
Technical field
The present invention relates to expanding breast tissues outside the software negative pressure under a kind of environment for nuclear-magnetism to fix device, belongs to doctor
Instrument field is treated, is specifically for use in the mammary gland intervention operation under MRI environment.
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 form belongs to squash type, can only be by way of extruding to breast tissue in order to be bonded breast tissue
Lesion is fixed, and increases the distress level of patient in the course of surgery, and fixed device quickly can not be adjusted and be locked, separately
Distance is excessive between outer each ring, can not realize that the comprehensive envelop-type of simulation manpower mode is fixed to breast tissue.
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；More importantly the invention fixed form is still
Belong to squash type fixed form, to obtain lesion point by way of squeezing patient's breast tissue, the fixed form of squash type and
Rigid reduces the level of comfort of patient, increases the distress level of patient.
The number of applying for a patent is that the patent of invention of 201810424535 X discloses the encircling type under a kind of environment for nuclear-magnetism
The fixed device of breast tissue is made of four identical finger plate mechanisms, circumferentially symmetrical point of four finger plate mechanisms
Cloth, two neighboring finger plate mechanism is interlaced, and is produced from the gap by adjusting the fixed flexible link of each arc in finger plate mechanism
Raw operative space, auxiliary doctor carries out the biopsy procedure of breast tissue, but the fixed form of the invention is by four finger plates
The overlapped clamping breast tissue of mechanism, even if finger plate mechanism uses flexible material, fixed form is still using crowded
Pressure type fixed form, which can not be bonded fixed breast tissue of different shapes well, likewise, the fixation side
Formula belongs to squash type, needs to squeeze patient's breast tissue to obtain patient's breast tissue lesion intervention point, significantly increases disease
The distress level of people.In addition, the operative space generated by each finger plate organizational overlapping is too small, it is unfavorable for breast tissue
The intervention of biopsy procedure.Described in summary, the present invention to solve the above problems, is devised a kind of under nuclear-magnetism environment
The fixed device of the outer expanding mammary gland of software negative pressure.
The fixed device of the existing mammary gland of comprehensive analysis, it is single that discovery remains fixed form, and it is solid to be all made of squash type
Determine mode, fixed form is not flexible to cause breast tissue to be squeezed, so that squash type deformation occurs for breast tissue, is unfavorable for hand
The problems such as art intervenes, and device is cumbersome, structure is complicated, heavy and surgical procedure narrow space, therefore design a kind of use
The fixed device of expanding breast tissue is very necessary outside software negative pressure under nuclear-magnetism environment.
