Description

Tonometry drag hook in rotator cuff neoplasty under a kind of arthroscope

Technical field

The utility model belongs to field of medical technology, is related to a kind of rotator cuff position clinical operation apparatus, in particular to a kind of Tonometry drag hook in rotator cuff neoplasty under arthroscope.

Background technique

In rotator cuff tendon repair surgical procedure, the two sides tendon that breaking part bounces back is needed to be stretched to fixation in situ, carried out Suture.The process that tendon stretches generally is completed using drag hook, and traditional drag hook, which only has, is drawn together alignment for two sides tendon Traction function, tendon stress is uncontrollable in surgical procedure, and it is high to the doctors experience requirement of operation how to control tensile stress.And root According to both domestic and external studies have shown that the operation of rotator cuff tendon repair is during stretching tendon, tension is too small, then is easy to cause healing Slowly, healing not exclusively, restore after tendon function reduction, therefore, when practical operation, mostly uses biggish tension-proof to heal；So And tendon tensile stress is excessive, then may cause tight at tendon suture, post operative recovery procedures, there may be two when tendon is exerted oneself Secondary tearing.Current tendon repair operation Tensity size is uncontrollable, and whether tendon tension is properly wanted the micro-judgment of doctor Ask high.

Summary of the invention

Utility model aims to solve current tendon repair operation tendon tensile stress size is uncontrollable, and flesh Whether tendon tension provides a kind of arthroscope under in rotator cuff neoplasty tension survey properly to the demanding problem of the micro-judgment of doctor Measure drag hook.

The technical scheme adopted by the utility model to solve the technical problem is as follows: being opened in rotator cuff neoplasty under a kind of arthroscope Power measures drag hook, from back to front successively includes handle, elongation bar, coupler body, it is characterised in that: and the elongation bar is hollow straight pipe, Coupler body is the hollow swan-neck being connected to elongation bar, and the elongation rod rear end is inserted into handle, and the side of handle front opens up threading Slot, the threading groove slot bottom are connected to elongation rod rear end, form the suture channel of threading groove, elongation bar, coupler body, the handle Rear end ring week be equipped with indent card slot, handle rear end embrace accompany chest expander, chest expander includes mutually nested inner and outer tubes, The front end of inner tube is set in outside handle rear end, and inner tube front inner wall is equipped with the fixture block of the expandable cooperated with card slot, outside Pipe sleeve is located at outside inner tube, and tension spring is equipped between inner tube rear end and outer tube, and the side of outer tube is embedded with transparent window along axial direction, Transparent window mid labels have pointer, and the side of inner tube is aligned the dynamics bar for being provided with and axially extending with transparent window. The present apparatus is held on the outer tube of chest expander in surgical procedure, embodies the tensile stress of drag hook in transparent window.Pulling force Device and handle are detachable, and handle and elongation bar, drag hook are structure as a whole, and directly to contact organization of human body, whole emphasis are needed to disappear Poison；Chest expander is postposition component, and not with human contact, level of sterilization requires lower.Suture is worn from the threading groove of handle side Enter, be pierced by from coupler body front end, can directly be sutured after the completion of drag hook traction.The phase of chest expander dynamics bar and pointer The size that drag hook tensile stress can be shown to position allows operative doctor to can control tensile stress size, reaches better hand Art effect.

Preferably, the dynamics bar uses gradient color from shallow to deep from back to front.Dynamics bar is using gradually Discoloration is without avoiding the puzzlement for needing doctor closer to read in surgical procedure, can directly be directed to from finger using specific reading The dynamics bar color depth answered judges whether Tensity size is suitable.

Preferably, said inner tube inner wall is uniformly provided with several fixture blocks, the front end of fixture block is inclined-plane, fixture block rear end is radial Plane, spring is equipped between the outside and inner pipe wall of fixture block, said inner tube side wall is additionally provided with the button of protrusion, the button Inner end and fixture block between be equipped with lever, against the rear end of lever, lever front end is plugged in the rear end of fixture block for button inner end.Fixture block It using conventional elastic clamping block, is inwardly pushed up and is set using spring offer thrust, exited outward using button driving fixture block.

Preferably, the slot bottom of the handle rear end card slot is the polyhedral structure being coaxially disposed with handle, avoid performing the operation Handle rotates in the process.

Preferably, the front side wall of the card slot be inclined-plane, card slot rear wall be radial plane.

Preferably, the front end of the handle is tapered that outer diameter is gradually reduced, the outer diameter of the elongation bar is less than hand The diameter of handle front end face, the coupler body are oblate cross-sectional, and the width of coupler body the widest part is no more than the outer diameter of elongation bar.The present apparatus Size more forward is smaller, protrudes into convenient for the instrument of Minimally Invasive Surgery.The coupler body of oblate cross-sectional gently locate for stretch tendon by Power face, avoids stress from concentrating.

Preferably, the curvature of the coupler body is no less than 120 degree.The curved curvature of coupler body wants sufficiently large, avoids tendon de- Uncinate gyrus contracting causes secondary injury.

The utility model embodies the tendon tensile stress in rotator cuff tendon repair surgical procedure using chest expander, makes The tensile stress of tendon controls in suitable range, i.e. guarantee surgical effect, and avoids secondary tearing.
