Abstract
The invention discloses a kind of medical operating instruments to be engaged position surface texture, it is in existing medical instrument structure, the surface for clamping occlusion tissue is fabricated to solid matter hexagonal prisms structure, during wet and slippery histoorgan is clamped, the groove formed by solid matter hexagonal prisms structure can arrange rapidly contact surface mucus, it is touched so as to fulfill affixed, chucking power is provided.Wherein the section configuration of hexagonal prisms is regular hexagon or irregular hexagon.The design can effectively clamp that wet and slippery histoorgan is not easily to fall off, while can reduce the damage to histoorgan.
Description
Technical field
The present invention relates to a kind of occlusion position surface topography designs of medical operating instrument, and the topographic design is in medical hand
It can effectively clamp that wet and slippery histoorgan is not easily to fall off in art, while the damage to histoorgan can be reduced, belong to medical instrument skill
Art field.
Background technology
Medical instrument refers in medical domain for the various instruments of clinical conditions, medical experiment and clinical examination
Various equipment.Since the life of curative activity and people are closely bound up, Safety in Medical Equipment is reliably extremely important, to the biology of material
Compatibility, fungi-proofing property, reliability of structure suffer from very high requirement.In addition, in all kinds of unrestrained long and complex surgical procedures, if
Standby ease for operation also becomes particularly important.
In all kinds of medical instruments, Medical clamp is essential, such as movement in all operations to blood vessel, solid
It is fixed, to movement, fixation of organ etc. in organ transfer operation.Since the tissue secretions such as human vas, organ have a large amount of tissue fluid,
So that surface is extremely wet and slippery, the simple dentalation of general surgery clamp is difficult to clamp；And tissue is very soft, energetically
Tissue damage, extravasated blood are susceptible under clamping, and then tissue growth is caused to adhere to, infect, bleeding or situations such as fistula, is finally made
Tissue organ function lacks of proper care and generates other complication.To reduce live body soft tissue or organ wounds, clamp certainly will be required to prevent
It slides to realize " pine folder is without slipping ".At present, work(under the conditions of the cognition to live body soft tissue injury mechanism and surgical environments is lacked
Can surface texture Optimization Theory, rely only on the conventional methods such as simple coating technology, age of a draught animal optimisation technique be difficult meet it is minimally invasive
The efficient anti-adhesion anti-slip requirement of medical instrument.
Present patent application is by tree frog bionics fiber, proposing a kind of new medical operating instrument occlusion position table
Face structure, the structure can effectively clamp histoorgan, at the same it is damaged be reduced to it is minimum.
The content of the invention
1st, purpose：The object of the present invention is to provide a kind of medical operating instrument occlusion position surface topographies to design, it
It is not easy to fall off enough and the shortcomings of be easy to cause injuries of tissues and organs to overcome existing instrument gripping strength so that medical hand
Art instrument realizes the ideal effect of " pine folder is without slipping ".
2nd, technical solution：Foregoing in order to achieve the purpose that, realization technical solution of the invention is as follows：A kind of medical operating folder
The occlusion position surface topography design of holder tool, in existing medical instrument structure, the surface for clamping occlusion tissue is made
Into solid matter hexagonal prisms structure, by hexagon into groove can arrange contact surface mucus rapidly, to provide in clamping process
Required frictional force, the section configuration of the hexagonal prisms structure is regular hexagon or irregular hexagon.
Wherein, the cross section of the hexagonal prisms is hexagon, and side size range value is 1 μm between 2mm.
Wherein, the altitude range value of the hexagonal prisms is 1 μm between 1mm；
Wherein, the width range value of the regular hexagon or irregular hexagon adjacent trenches is 0.5 μm between 1mm；
Wherein, the medical operating instrument occlusion position surface texture, i.e., solid matter hexagonal prisms structure by chemical etching,
Nano impression, laser engraving or 3D printing method are made；
Wherein, the material at medical operating instrument occlusion position is metal, ceramics or high molecular polymer.
Wherein, medical operating instrument is surgical clamp or ultrasound knife.
3rd, advantage and effect：Compared with traditional dentation clamp structure, the present invention is capable of providing higher frictional force so that folder
It holds not easily to fall off；It is not falling off equally, the chucking power smaller of application causes site of tissue damage less；Meanwhile it clamps
Also from beam-shaping effect.

Specific embodiment
Below in conjunction with drawings and examples, the present invention is described in further detail.
See Fig. 1, Fig. 2, be existing medical instrument surgical clamp and occlusion position appearance structure figure.
1 is general surgery pincers, and 11 be that general surgery clamps the first bite, and 12 be that general surgery clamps the second bite；
See Fig. 3-Fig. 8, be that the present invention first, second implements illustration.
2 be first embodiment surgical clamp, and 21 be the first bite of first embodiment surgical clamp, and 22 be first embodiment operation
Clamp the second bite；3 be second embodiment ultrasound knife, and 31 be second embodiment ultrasound knife bite, and 311 be that second embodiment is stung
Conjunction portion hexagonal prisms.
The present invention is in existing medical instrument structure, and the surface for clamping occlusion tissue is fabricated to solid matter hexagonal prisms
Structure, by hexagon into groove can arrange contact surface mucus rapidly, to provide required friction in clamping process
Power, the section configuration of the hexagonal prisms structure is regular hexagon or irregular hexagon.
Wherein, the length of side value of first embodiment regular hexagon or irregular hexagon is 300 μm；
The height value of first embodiment hexagonal prisms height, that is, regular hexagon or irregular hexagon is 40 μm；
First embodiment regular hexagon or the width value of irregular hexagon adjacent trenches are 50 μm.
Wherein, the length of side value of second embodiment regular hexagon or irregular hexagon is 60 μm；
The height value of second embodiment hexagonal prisms height, that is, regular hexagon or irregular hexagon is 35 μm；
Second embodiment regular hexagon or the width value of irregular hexagon adjacent trenches are 20 μm.
The present invention by by medical instrument dentation occlusion structure 11, be changed to solid matter hexagonal prisms structure (21,22,
211,31,311) play the role of anti-skidding, be less susceptible to come off so that clamping wet and slippery organizer official rank.Due to histoorgan in contact
It deforms small, it is damaged and is also reduced.
