Description
Technical field
The present invention relates to hand surgical knife technical field, in particular to one kind is exclusively used in twolip stndon sheath part exsector.
Background technique
In the prior art, finger when the narrow stndon sheath of cut-out hand using coventional scalpel prior to stndon sheath middle part surface
Take a row notch on skin, cut skin and it is subcutaneous, appear stndon sheath, then first longitudinally cut to remote, proximal end respectively with scalpel
Narrow stndon sheath is opened, is distinguished again at the width at the stndon sheath edge, excision stndon sheath as needed that are then cut again with vessel forceps clamping
Xiang Yuan, the longitudinal each incision in proximal end are primary, can achieve the purpose that part stndon sheath is cut off.Often because small notch exposure is limited, patient helps
Hand channel tests that insufficient, coventional scalpel blade is longer, move under water in Limited eyeshot cut twice, longitudinally slit stndon sheath while by skin
Skin is also cut, and make to design originally becomes like " 10 " word structure " mistake " notch, two along the row specification notch of dermatoglyph
Secondary excision is cumbersome, operating difficulty increases, while having longitudinal splitting tendon to cause tendon injury, increase adhesion, accidentally injure neural blood
The risk of tube bank, cause postoperative wound scar pain, even contracture, the recurrence of adhesion of tendon card pressure, wound unsightly, it is even medical
Dispute.
Summary of the invention
The purpose of the present invention is to solve the deficiencies in background technique, provide one kind and are exclusively used in the excision of twolip stndon sheath part
Knife.

Preferably, first blade and blade edge distance H are 1mm.
Preferably, the thickness of first blade and the second blade is 1mm.
Beneficial effects of the present invention:
The configuration of the present invention is simple cooperates original general surgery knife handle to use, it is only necessary to once safety, quick, effectively excision
Part stndon sheath, needed when solving the use of original knife blade repeatedly small space operation difficulty it is big, by specification transverse incision not
When being cut into " mistake " Notch Problems of similar " 10 " word while eliminating the potential risk of tendon neural blood vessel damage, keep away
Numbness, limitation of activity caused by zigzag incision cause cicatricial contracture, pain and tendon neurotrosis adhesion that fault-avoidance misses etc. draws
The medical tangle of hair.

Specific embodiment
Shown in please referring to Fig.1 to Fig.4, one kind is exclusively used in twolip stndon sheath part exsector, including blade 1, the first blade 2,
Second blade 3 and connecting pin 4,1 upper end of blade are symmetrically arranged with the first blade 2 and the second blade 3, and the end of blade 1 is connected with
Head end of the working end of connecting pin 4, the first blade 2 and the second blade 3 towards blade 1；
The blade 1 is arc groove structure；
First blade 2 is identical with 3 structure of the second blade；
Mounting groove 5 is provided on the connecting pin 4；
The 1 width A of blade is 7.5-8mm.
Included angle B between 1 two sides of blade and horizontal plane is 8~12 °.
Angle F between first blade 2 and horizontal plane is between 75 °~85 °.
Preferably, the 1 width A of blade is 7mm.
Preferably, the included angle B between 1 two sides of blade and horizontal plane is 10 °.
Preferably, the distance between first blade 2 and 1 head end of blade C are 3mm.
Preferably, the distance between first blade 2 and 1 end of blade D are 15mm.
Preferably, the height E of first blade 2 is 3mm.
Preferably, the angle F between first blade 2 and horizontal plane is 80 °.
Preferably, the distance between first blade 2 and the second blade 3 G are 3mm.
Preferably, first blade 2 and 1 edge distance H of blade are 1mm.
Preferably, the thickness of first blade 2 and the second blade 3 is 1mm.
The working principle of the invention and use process:
Shown in please referring to Fig.1 to Fig.4, in use, first by the mounting groove 5 and general surgery knife handle on 1 connecting pin 4 of blade
Connection, after the completion of connection.The row notch along dermatoglyph is taken on finger skin prior to the quasi- stndon sheath middle part surface cut, is used
General surgery blade percutaneous incision skin and subcutaneous, separation appear stndon sheath, separate subcutaneous tissue with drag hook drawing or vessel forceps, with common
Part stndon sheath about 8mm immediately below knife blade transection notch, then 1 head end of blade of the invention is split from the stndon sheath cut
Mouth is first proximally facing, is inserted into below stndon sheath, tendon superficial surface, proximally pushes away along stndon sheath direction, the first blade 2 and the second blade 3
The proximal part stndon sheath of width about G will be cut off as needed simultaneously；Blade 1 of the invention is exited again, the stndon sheath that head end is cut certainly
Breach is re-directed towards distal end, insertion stndon sheath lower section, tendon superficial surface, and Xiang Yuanduan is pushed away along stndon sheath direction, the first blade 2 and the second blade
3 by the distal portions stndon sheath of excision width about G, completion are performed the operation as needed simultaneously.
Firstly, because usual by largely autopsy research and the clinical practice of conventional therapy observation, discovery
The stndon sheath length for needing to cut generally in 30mm, and we perform the operation in select along dermatoglyph notch and the first blade 2 with
The initial cut location of second blade 3 generally in the middle part of sheath, therefore the first blade 2, the second blade 3 and 1 end of blade it
Between distance D be 15mm；The distance between the first blade 2, the second blade 3 and 1 head end of blade C are 3mm, make blade 1 simultaneously
Head end is from after the stndon sheath insertion of first partial cut, the first blade 2 is increased with the distance between 1 head end of blade C portion blade by deep
Hyperplasia stndon sheath that thick tendon and shallow-layer is not cut, which is stablized, to be blocked so as to cut direction controllability more preferable, therefore, the first blade 2,
The distance between second blade 3 and 1 head end of blade C are 3mm, the distance between the first blade 2, the second blade 3 and 1 end of blade
D is 15mm, as 1 total length of blade about 20mm.
Secondly, in view of good passability when blade 1 is placed in from stndon sheath breach, pushing away the flexing resistance needed when cutting and attached
Add the feasibility of the first blade 2,3 integrally casting shaping of the second blade, while to prevent blade the first blade 2, the second blade 3 too
Thin dissection is poor, technique realize it is difficult and have fracture cause foreign matter residual, even cause medical tangle may, we are by blade 1
Width A be designed as between 6.5mm~7.5mm, blade is designed as the folder of the first blade 2, the second blade 3 between horizontal plane
Angle F is between 75 °~85 °, height E is 2.5mm~3.5mm, with a thickness of 1mm, the first blade 2, the second blade 3 away from blade edge
Distance H be distance G between 1mm, the first blade 2, the second blade 3 be 3mm.And for avoid blade 1 push away cut stndon sheath during,
The tendon in frictionally damage deep, we by the cross section of blade 1 be designed as arc groove structure, 1 two sides of blade and horizontal plane it
Between included angle B be 8~12 ° and chamfered have been done to edge.
Finally, the size of mounting groove 5 is performed the operation referring to national standard because blade 1 will connect use with existing general surgery knife handle
Knife handle distal end card slot size；Simultaneously in view of the obstruction of horizontal direction upper limb body during avoiding blade from pushing needs knife handle and water
Plane has certain angle, in conjunction with patient using other similar surgical instrument convenient and habit angle, connecting pin 4 and horizontal plane it
Between angle be 50 °~70 °.
