Description

A kind of rotary armpit approach cavity mirror thyroid operation retractor

Technical field

The utility model relates to the field of medical instrument technology, more particularly, to a kind of rotary armpit approach device for endoscopic thyroid Hook for surgery operation.

Background technique

For conventional open thyroid operation usually because doing row notch in neck, postoperative neck scar pimple hyperplasia influences beauty See, perplex the life of patient, with minimally invasive theory continuous expansion extensively, the update of laparoscopic operation method and instrument it is continuous into Step, neck are gradually appeared without the operation of keloid.The development that past more than ten years device for endoscopic thyroid surgery is advanced by leaps and bounds, There are various art formulas, such as full breast areola approach, armpit mammary areola pathway, single hole mammary areola pathway, armpit assisted laparoscope etc..Closely It successively reports over year and performs the operation through axillary approach device for endoscopic thyroid single hole, use U-shaped in the operation of axillary approach device for endoscopic thyroid single hole The drag hook of shape is by epidermal tissue's pull-up of the armpit of patient to neck.

China Patent Publication No. is that CN205379323 discloses a kind of goitre retractor with antiskid function, including draws Bar and the first drag hook and the second drag hook that pull rod both ends are set, if the inner surface of first drag hook and the second drag hook is provided with Convex grain is done, the first drag hook, the second drag hook and convex grain are made of one piece.In surgical procedure, it is attached that the second drag hook protrudes into patient's armpit In close surgical aperture, the first drag hook is above mentioned, the second drag hook is by epidermal tissue's pull-up of the armpit of patient to neck, thus shape At surgical procedure space, facilitates doctor to be inserted into surgical instrument and the surgical procedures such as shear, clamp, but human cuticular tissue It is limited to pull up rise, causes surgical procedure narrow space, surgical procedure difficulty is larger, is easy to appear fault.

Summary of the invention

The utility model is the hardly possible of surgical procedure caused by order to overcome prior art armpit approach surgical procedure narrow space Larger problem is spent, to provide one kind can expand armpit approach surgical procedure space, facilitate doctor is subsequent to be operated Thyroid surgery wire retractor.

To achieve the goals above, the utility model uses a kind of following technical scheme: rotary armpit approach hysteroscope first Shape gland hook for surgery operation including pull rod and is arranged in the first drag hook and the second drag hook that pull rod two sides are parallel to each other, further includes being set to The tie point of sawtooth telescopic rod and compression bar below second drag hook, the pull rod and the second drag hook and the upper end of sawtooth telescopic rod are solid Fixed connection, the lower end of the sawtooth telescopic rod and one end of compression bar are rotatablely connected, and the other end of the compression bar, which is equipped with, to be bent downwardly Crotch, the compression bar and the second drag hook are located at the same side of sawtooth telescopic rod.

First drag hook is for slinging entire lifting hook device；The effect of second drag hook is by the table of the armpit of patient to neck Skin tissue pull-up facilitates doctor that surgical instrument insertion is sheared, clamped etc. and performed the operation to form surgical procedure space Journey；Since surgical procedure mesocuticle tissue and the back visibibility of lower muscle tissue are blocked by musculature, cause to implement hand Art is difficult, and musculature can be pushed, so that the visual field at musculature rear is sufficiently exposed, be greatly reduced by compression bar The difficulty of operation facilitates doctor to implement operation, reduces surgical error；The effect of sawtooth telescopic rod be reduce patient tissue damage and The size in surgical procedure space can be freely adjusted, before the second drag hook and compression bar protrude into patient's armpit operation opening, shortens sawtooth Telescopic rod reduces the distance between the second drag hook being parallel to each other and compression bar, doctor is facilitated to protrude into the second drag hook and compression bar Patient's armpit operation opening, reduces the unnecessary damage of patient body tissue, and the second drag hook and compression bar protrude into the operation of patient's armpit After opening, can according to the needs in surgical operation space, freely adjust space size between the second drag hook and compression bar and The field range at musculature rear, facilitates doctor to carry out implementation operation below epidermal tissue；The lower end of sawtooth telescopic rod and pressure One end of bar is rotatablely connected, and compression bar not only can move up and down, and pushes musculature, can also be rotated freely as needed certain Angle, make between musculature and surface texture formed specific shape surgical procedure space and visual-field space, further side Doctor implement operation；It is that the muscle of epidermal tissue lower part is outside that the other end of compression bar, which is equipped with the downward crotch effect in direction, It stretches, increases surgical procedure space and the field range at musculature rear.

Preferably, the inner surface of the crotch is equipped with several dot bulges.

The effect of dot bulge is to increase the frictional force of crotch and musculature, and crotch is not easy to slide relatively with musculature It is dynamic.

Preferably, the sawtooth telescopic rod includes saw teeth bars and the loop bar that is sheathed on outside saw teeth bars, the saw teeth bars Outer wall longitudinal direction is equipped with sawtooth, and screw hole and the compatible screw of screw hole are equipped on the outside of the loop bar, and the screw passes through spiral shell Hole is connected in the sawtooth in saw teeth bars.

When needing to extend sawtooth telescopic rod, after the screw on the outside of loop bar is unscrewed, saw teeth bars and loop bar is stretched, sawtooth is stretched Contracting bar is elongated to suitable length, then tightens screw, is clamped screw mutually with the sawtooth in saw teeth bars, stretches to play fixation The effect of contracting saw teeth bars.By stretching the mutual cooperation sliding of saw teeth bars and loop bar, the freedom of Lai Shixian sawtooth length of telescopic bar It adjusts, increases the distance between the second drag hook and compression bar, expand surgical procedure and visual-field space.

Preferably, the end of second drag hook is equipped with pulling-on piece, the plane where the pulling-on piece is mutually perpendicular to pull rod.

The effect for the pulling-on piece that second drag hook end is equipped with is to increase the contact area of the second drag hook and epidermal tissue, to increase Add the spatial dimension between epidermal tissue and lower muscle, increases surgical procedure space.

Preferably, second drag hook is a hollow draw-bar, the internal sleeve of the hollow draw-bar is equipped with Smoking pipe.

During being performed the operation, operation smoke can be generated in surgical procedure space, it can be by body by Smoking pipe Interior operation smoke is sucked out, and prevents smog from blocking operation sight.

Preferably, the lower part of the pulling-on piece is equipped with headlamp.

Headlamp can increase the brightness in surgical procedure space, and the visual field is made to become clear.

Therefore, the utility model has the following beneficial effects: (1) increases surgical procedure space and field range；(2) basis Surgical procedure space needs the shapes and sizes in changeable surgical procedure space；(3) surgical procedure gets a clear view；(4) operation behaviour Facilitate.
