Abstract
A kind of slip push broach suitable for carpal tunnel syndrome Minimally Invasive Surgery, belong to surgical medical equipment technical field, avoid the median nerve below canalis carpi from causing to damage during ligamentum carpi transversum for cutting.Its technical scheme is：Base is rectangular slab, plane has chute on base, blade is rectangle, blade is disposed vertically, and a long side of blade is embedded in chute, and blade is to be slidably matched with chute, the short side of the oblong forward portion of blade is cutting edge, blade connects push rod, and the front end of handle is connected with the rear end of base, and the body of rod of handle tilts to oblique back upper place.Base of the present utility model can prevent the median nerve below canalis carpi from being damaged by blade, blade is slided in chute, and the ligamentum carpi transversum in front of blade can be cut, the closing of chute front end, the edge of a knife of blade avoids the accidental injury to the nerve fiber in front no more than pan frontward end.The utility model is simple in construction, easy to use, can not have to the cooperations such as endoscopic system and be used alone.
Description
Technical field
A kind of operating theater instruments for treating carpal tunnel syndrome is the utility model is related to, belongs to surgical medical equipment technical field.
Background technology
Carpal tunnel syndrome (carpal tunnel syndrome) is most commonly seen one in Peripheral nerve entrapment syndrome
Kind, for median nerve in wrist by a series of symptoms and sign caused by card pressure.It is apt to occur in 30~50 years old age, Nv Xingwei
5 times of male, bilateral hair patient account for 1/3~1/2, and it is 9 to 1 that bilateral, which sends out patient women and the ratio of male,.Due to wrist just
Middle nerve compression, thumb, forefinger, middle finger produce pain and often show as the sensory disturbance of finger tip at stolidity, initial stage, often
Often cause to wake up because of a few hours appearance numbness or burning pain after sleep, alleviate after activity, small number of patients occurs because the course of disease is longer
Neural malnutrition, muscle of thenar atrophy, intermittent skin whitening, cyanosis occurring, severe patient may occur in which thumb, forefinger cyanosis,
Finger tip necrosis or atrophic ulcer, therapeutic modality is mainly expectant treatment and operative treatment at present.
The major way of operative treatment has Minimally Invasive Surgery mode under conventional therapy mode, arthroscope, single or double small
Incision modus operandi.The apparatus that ligamentum carpi transversum is cut off in treated via arthroscope carpal tunnel syndrome is miniature push broach, miniature
The edge of a knife front bottom end of push broach is designed with the flat support of ellipse, and its most leading edge is about 0.5 cm compared with the edge of a knife, is matched with half-open more
Put U-type groove sleeve pipe (German Wolf companies), endoscopic system (Sony corporation of Japan) operation.This system operation is costly, operation
Skill requires that height, surgical technic are immature, is not suitable for single or Mini-incision Minimally Invasive Surgery mode and treats carpal tunnel syndrome.Such as
Fruit is performed the operation using this miniature push broach for mini-invasive incision, and because its distal end is flake, no median nerve protection device is easily right
Median nerve cutting below canalis carpi causes to damage.Therefore, currently without suitable for single or Mini-incision Minimally Invasive Surgery mode
The effective apparatus of ligamentum carpi transversum is cut, single or Mini-incision Minimally Invasive Surgery mode is have impact on and treats carpal tunnel syndrome, urgently
Wait to solve.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of slip suitable for carpal tunnel syndrome Minimally Invasive Surgery
Push broach, this slip push broach can avoid the median nerve below canalis carpi from causing to damage during ligamentum carpi transversum is cut, really
The safety of median nerve is protected, ensures being smoothed out for operation.
Solve above-mentioned technical problem technical scheme be：
A kind of slip push broach suitable for carpal tunnel syndrome Minimally Invasive Surgery, it is made up of base, blade, push rod, handle, bottom
Seat be rectangular slab, and plane has chute on base, and chute is along the rectangular length direction of base, and chute is in pan frontward end envelope
Close, blade is rectangle, and blade is disposed vertically, and the rectangular long side of blade is located at horizontal direction, blade it is rectangular short
Side is located at vertical direction, and a long side of blade is embedded in chute, and blade is to be slidably matched with chute, the oblong forward portion of blade
Short side be cutting edge, the short side connection push rod at the rectangle rear portion of blade, push rod tilts to oblique back upper place, and handle is stock,
The front end of hand is connected with the rear end of base, and the body of rod of handle tilts to oblique back upper place.
The above-mentioned slip push broach suitable for carpal tunnel syndrome Minimally Invasive Surgery, the front end of the base is circular arc, base
Bottom surface is plane, and the upper plane of base is circular arc.
The above-mentioned slip push broach suitable for carpal tunnel syndrome Minimally Invasive Surgery, the cutting edge of the blade is middle to be recessed backward
Circular arc.
The above-mentioned slip push broach suitable for carpal tunnel syndrome Minimally Invasive Surgery, the folder between the handle bar body and base plane
Angle is 130 ° -160 °, there is the annular knurl or striped of increase frictional force in handle bar body.
The beneficial effects of the utility model are：
The utility model has base below blade, and base can prevent the median nerve below canalis carpi from being damaged by blade
Wound, blade slides in the chute of plane on base, the ligamentum carpi transversum in front of blade can be cut, and end seal before chute
Close, limitation blade moves forward, and the edge of a knife of blade avoids the mistake to the nerve fiber in front no more than pan frontward end
Wound.The utility model is simple in construction, easy to use, improves the deficiency of traditional push broach, it is ensured that median nerve below canalis carpi
Safety, and the cooperations such as endoscopic system can not had to and be used alone, surgery cost is cheap, is worthy of popularization.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is front view of the present utility model；
Fig. 3 is side view of the present utility model.
Marked in figure as follows：Base 1, blade 2, push rod 3, handle 4, chute 5.
Embodiment
