Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of slide plate knife of carpal tunnel syndrome.
Background technique
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 signs 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 about 1/3~1/2, and it is 9 to 1 that bilateral, which sends out patient women and the ratio of male,.Just due to wrist
Middle nerve compression, thumb, index finger, middle finger generate pain and stolidity, initial stage often show as the sensory disturbance of finger tip, often
Often there is numb or burning pain due to cause to wake up in a few hours after falling asleep, and alleviate after activity, small number of patients occurs since the course of disease is longer
Muscle of thenar atrophy occurs for neural malnutrition, and therapeutic modality is mainly conservative therapy 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 instrument 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 design of push broach has the flat support of ellipse, and most leading edge is about 0.5 cm compared with the edge of a knife, and polygamy is together in half-open
Put U-type groove casing (German Wolf company), endoscopic system (Sony Corporation of Japan) operation.This system operation is costly, performs the operation
Skill requires height, surgical technic 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 protective 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 instrument of ligamentum carpi transversum is cut, single or Mini-incision Minimally Invasive Surgery mode is affected and treats carpal tunnel syndrome, urgently
Wait solve.
Summary of the invention
It is divided into lever piece, grip section the purpose of the present invention is to provide the pedestal and holds section, the lever piece, grip
Section and holding section are integrated；
The lever piece front end be it is arc-shaped, from lever piece rear end to lever piece front end at it is gradually thinning, set on the lever piece
There is a blade, the blade is perpendicular to the lever piece, and cutting edge is towards operating side leading portion on front side of the blade, before the grip section
End is connected with the rear end of lever piece, and rear end is connected with section is held, and the holding section and the grip end are in angle.
Further, the lever piece is 50-60mm, and the grip section is 20-30mm, and the holding section is 50-60mm.
Further, the lever piece leading portion is horizontal by 3-6 ° of angle.
Further, the lever piece front end is round and smooth without sharp.
Further, the blade is integrated with the lever piece.
Further, blade both ends are stated and are equipped with cutting edge, front end cutting edge is intermediate forwardly convex arc-shaped, rear end cutting edge
Arc-shaped for what is concaved, the blade tip is round and smooth.
Further, the blade is 10-20mm at a distance from the lever piece front end.
Further, the blade height is 3-5mm, width 15mm, thickness thickness are 2mm.
Further, the grip section is equipped with the annular knurl or striped for increasing frictional force.
Further, the angle held between section and the grip section is 130 ° -160 °.
The beneficial effects of the present invention are:
(1) present invention has pedestal below blade, and the median nerve below canalis carpi can be pressed by the circular arc of pan frontward end
It prevents from being damaged by blade below to blade.
(2) edge of a knife of blade is no more than pan frontward end, therefore avoids the accidental injury to the nerve fiber in front.
(3) using grip section and holding section, stress is more steady when pushing the invention to inside of human body.
(4) the configuration of the present invention is simple, easy to use, improves the deficiency of traditional push broach, it is ensured that the center mind below canalis carpi
The safety of warp, and the cooperations such as endoscopic system can not had to and be used alone, surgery cost is cheap, is worthy of popularization.
