Specific embodiment
It please refers to shown in Fig. 1 to Fig. 8, a kind of ligamentum carpi transversum incision knife, including blade 1, blade 2 and knife handle 3, blade 2 connects
It connects on 1 top of blade, blade 1 is connect with knife handle 3, and 2 working end of blade is towards knife handle 3;
1 head end of blade setting fluted 10,1 end of blade are provided with mounting groove 11, and the cross section of blade 1 is arc groove
Structure;
Included angle A between the blade 2 and horizontal plane is between 65 °~85 °;
Angle I between the knife handle 3 and horizontal plane is between 45 °~75 °;
The distance between blade 2 and mounting groove 11 F are 35~45mm in the blade 1;
The 1 width B of blade is 7.5mm~8.5mm;
Angle E between 1 two sides of blade and horizontal plane is 8 °~12 °;
3 front end of knife handle is provided with the protrusion to match with 1 end mounting groove 11 of blade.
Preferably, the included angle A between the blade 2 and horizontal plane is 80 °, and the 1 width B of blade is 8mm.
Preferably, the angle I between the knife handle 3 and horizontal plane is 60 °
Preferably, the distance C of 1 head end of blade away from blade 2 is 10mm, and the 1 thickness D of blade is 2mm, described
1 two sides of blade and horizontal plane between angle E be 10 °.
Preferably, the distance between blade 2 and mounting groove 11 F are 40mm in the blade 1.
Preferably, the 2 total height G of blade is 5mm, and the thickness of knife edge H is 3mm.
Preferably, 3 end of knife handle and the angle before horizontal plane are 60 °, and the 11 length J of mounting groove is
15mm。
Preferably, on the knife handle 3 and anti-skid chequer is provided in the groove 10 of 1 head end of blade.
The working principle and use process of the present embodiment:
The present invention using when patient general anaesthesia, tie up tourniquet, disinfection, paving aseptic operation list, upper limb stretch is placed in operation
Platform is handed over when taking proximal end along rasceta, Tendon palmaris longus ulnar side row about 1cm notch, distal end fourth finger buckling position in finger tip and thenar line
Point is closely along thenar line stringer about 1cm notch.
With general surgery blade percutaneous incision skin and subcutaneously, appear deep ligament, protection deep tissue, cut-away portions ligament,
As needed or patient be accustomed to hand direction, at the groove 10 being arranged with 1 head end of vessel forceps retaining scalpel piece by knife blade 1
It is pushed from below distal end or proximal end notch internal ligament, the mounting groove 11 of knife blade 1 is made to reach another notch, pass through mounting groove
11 connect knife blade 1 with the protrusion of 3 head end of knife handle, by push-and-pull knife handle 3, persistently use vessel forceps retaining scalpel piece simultaneously
Maintenance level direction of propulsion is assisted at 10, blade 2 can be cut ligamentum carpi transversum, by with vessel forceps retaining scalpel piece
It can control the thickness cut with the dynamics under the push-and-pull cooperation of knife handle 3 vertically upward at groove 10.If ligament is not cut all once,
It can carry out repeating above-mentioned movement, at this moment separate knife handle 3 with blade 1, continue to select merging according to the needs for cutting ligament position
The direction of blade 1, merging blade 1, connection knife handle 3, again push cutting separate until thoroughly sufficiently cutting ligamentum carpi transversum
Knife handle 3 and knife blade 1 take out knife blade 1.
Firstly, because the shortest distance about 35~45mm between two notch that we select, to guarantee that blade 1 passes through one end notch
Merging ligament lower section, mounting groove 11 can be fully exposed to other end notch and be convenient for definitely installing with knife handle 3, and with push knife handle
3, the cutting overall process of blade 2 is all controllable exact, we design the distance between blade 2 and mounting groove 11 F in blade 1 and are
35~45mm.Secondly, in view of passability good when blade 1 is placed in from small notch, the flexing resistance of needs, additional blade 2 one
The feasibility of body casting and forming, the width design of blade 1 is 7.5mm~8.5mm by we, and to avoid blade 1 from being placed in and push away
Send cut ligament during, friction it is related by the tendon nerve in deep be caught in blade survey cause drawing, cutting equivalent damage, we will
It is 8 °~12 ° and opposite side that the cross section of blade 1, which is designed as the angle E between arc groove structure, 1 two sides of blade and horizontal plane,
Edge has done chamfered.In addition, finding wrist by largely autopsy research and the clinical practice of conventional therapy observation
Thickness is generally in 3-5mm after transverse ligament hyperplasia, and strong but pliable in texture, for prevent the too thin dissection of blade is poor, technique realize it is difficult,
And have fracture cause foreign matter residual, need open surgery take out even cause medical tangle may, therefore blade 2 is designed as blade
Included angle A between 2 and horizontal plane is between 65 °~85 °, height G is 5mm, thickness H is 3mm.Finally, in view of avoiding blade
During push the obstruction of horizontal direction upper limb body need knife handle and horizontal plane have certain angle, in conjunction with patient using other similar
The convenient and habit angle of surgical instrument, the angle I between knife handle 3 and horizontal plane is between 45 °~75 °.
