Medical operation nipper of the present invention, the nipper includes the upper and lower clamp being oppositely arranged of two panels, and clamp can be with being pressed from both sides
Hold the difference of thing size and adjust chucking power, so as to ensure gripped object uniform force, it is to avoid damage gripped object, reduction
Operation risk.
Clamp is prepared using elastic material, so as to realize that the clamp can be with the difference of gripped object size
And adjusting chucking power so that gripped object uniform force, the elastic deformation amount of elastic material is 0.5% ~ 10%.
Two panels or wherein a piece of clamp are prepared by niti-shaped memorial alloy, and niti-shaped memorial alloy martensite is to mother
The transformation end temp of phase is less than 37 DEG C.Remembered using martensitic phase to NiTi shape of the transformation end temp less than 37 DEG C of parent phase
It is for the super elastic characteristics of utilization niti-shaped memorial alloy to recall alloy.Under normal circumstances, people's body temperature is at 37 DEG C or so,
Niti-shaped memorial alloy now has super-elasticity, i.e., with the larger elastic deformability of deflection.In continuing for external force
Under effect, niti-shaped memorial alloy can strain induced martensite phase transformation, the larger elastic deformation of generation so that chela can when closing
The difference of local stress is overcome to keep uniform contact and the stress of working face so that clamped tissue uniform force, it is to avoid cause
Tissue damage, with preferable practicality.
The opening and closing of the nipper of the front end of connecting rod 4 are arranged on using the relative movement drives of ejector sleeve 5 and connecting rod 4,
Including the upper and lower clamp being oppositely arranged of connecting rod 4 and two panels, the clamp is connected to the front end of connecting rod 4 by elastic component 3,
The clamp includes clamp handle 2 and chela 1, and the chela 1 is connected by clamp handle 2 with elastic component 3；When two panels clamp is closed, institute
State chela 2 to be intermeshed, strip through-hole 6 constituted between the clamp handle 2, accommodate unnecessary or irregular tissue, beneficial to capturing or
Separation；The elastic component 3 refers to two flexible feets prepared using elastomeric material, and one end of two flexible feets is connected respectively
The upper and lower two panels clamp handle 2 being oppositely arranged, the other end is connected after merging with the front end of connecting rod 4, is clipped in external force disappearance forceps major
Recover open-shaped state in the presence of elastic component 3.Patient promotes ejector sleeve 5 to be moved forward with respect to connecting rod by external force, drives bullet
Property part 3 two flexible feets it is relative close up so that the clamp for being arranged on elastic component front end is relative, to close up be in gradually closed form
State, after external force disappears, ejector sleeve is gradually moved rearwards by recovery with respect to connecting rod to origin-location, two flexible feets of elastic component according to
Gradually opened by natural resiliency, drive clamp gradually to be opened by closing, overall structure is simple, easy to operate, easy processing and sterilization
Cleaning.
Connecting rod 4 is used before Split type structure, including connecting rod leading portion 41 and connecting rod back segment 42, connecting rod in the present embodiment
The front end of section 41 is connected with clamp, and the rear end of connecting rod leading portion 41 is provided with and the groove of the fitting connection of connecting rod back segment 42 and convex
Platform, the bolt or screw being either threadedly coupled with connecting rod back segment 42 or the card being connected with the rotary buckle of connecting rod back segment 42
Pin or neck.Clamp and a variety of attachment structures of connecting rod 4, consolidate and are convenient for changing different nippers or other functors, reduce
Consumer cost.Clamp, elastic component and connecting rod can be overall structure, or welding or bonding are overall structure, realize one
Change structure.
The clamp handle 2 and chela 1 of clamp are structure as a whole；Or be split-type structural, the chela 1 of the split-type structural leads to
Cross neck to be fixed in clamp handle 2, be either bonded in clamp handle 2 or splice in clamp handle 2, or be welded in clamp handle 2.Pincers
A variety of connected modes of handle 2 and chela 1 are convenient for changing the chela type required for crawl different tissues.
The opposite face of chela 1 is working face, on working face laterally, be spaced, be arranged with parallel the horizontal boss 7 of some rows and
Through whole working face, vertical groove 8 is vertically arranged with and through whole working face in working face；In two panels clamp closure
When, horizontal boss 7 is intermeshed, meanwhile, vertical groove 8 constitutes the through hole through whole working face, the cross section of the through hole
For circular, polygon or ellipse, and quantity is 1 ~ 2.Horizontal boss increases the frictional force with tissue, and grasping tissue is more
Plus conveniently, the through hole that longitudinal fluting is constituted is used as hole of bleeding, it is to avoid tissue is pressed from both sides dead or crushed.
In order to further optimize the crawl function of nipper, left side or right side of the clamp along closing direction are in arc shaped, its arc
The radian of line is 0 °~180 °；Or, upside or downside of the clamp along closing direction are in arc shaped, and the radian of its camber line is
Less than 90 °, to realize the separation or crawl of diverse location tissue.
The lateral surface of the flexible feet of elastic component and the contact site of ejector sleeve have axially been placed equidistant some positioning convex 31,
The port of ejector sleeve is provided with the positioning concave tooth matched with positioning convex.Increase the frictional force of flexible feet and ejector sleeve leg, side
Just the opening angle of clamp is controlled and fixed, alleviates patient's hand fatigue, facilitates patient to perform the operation.
Clamp can connect stations device and realize the functions such as coagulation, quick-acting haemostatic powder, to avoid patient's surgical procedure from getting an electric shock
Generation is unexpected, and clamp, elastic component and the exposed surface of connecting rod are coated with the smooth insulating barrier in surface in addition to chela working face,
Ensure to reduce the frictional force that clamp enters between the frictional force and ejector sleeve and elastic component of fault card while patient is safe, convenient pincers
Folder opens or closed, beneficial to operation technique, such as Teflon, ceramics or other macromolecule lubricious materials.
Chela face surface is coated with hard alloy layer or ceramic layer, strengthens the wearability of chela working face, and extension makes
Use the life-span.
Clamp be medical stainless steel, titanium alloy, nickel-base alloy, inconel, plastics, ceramics, high polymer material and its
His composite and above-mentioned material two or more combination.Material selection range is wide, it is possible to decrease cost, beneficial to pushing away
Extensively.
The beneficial effect of medical operation nipper of the present invention is that ejector sleeve makes to set with respect to connecting rod forward movement under external force
Put the nipper in connecting rod front end gradually to close, ejector sleeve recovers origin-location after external force disappearance, and the nipper of connecting rod front end exists
Gradually opened under the effect of elastic component its own resilient, overall structure is simple, easy to operate, reduce Product processing difficulty, easy cleaning disappears
Poison, nipper clamp and a variety of connected modes of connecting rod, not only reduce production cost but also are convenient for changing different type nipper, extend
Whole service life, niti-shaped memorial alloy clamp has superelastic properties, has and ensures tissue during stress adaptability, crawl
Uniform force, reduces damage and reduction operation risk, with good practicality.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in protection scope of the present invention.
