Abstract
The invention relates to a medical instrument, in particular to a minimally invasive surgery instrument for carpal tunnel syndrome. The instrument comprises an expansion tube and a probe used for being plugged in an inner cavity of the expansion tube, a connecting plate is arranged between a dilating catheter and the tube wall of the expansion tube, the connecting plate is an arc plate with the radian equal to that of the tube wall of the expansion tube, and the arc length of the arc plate is smaller than one fourth of circumference; the instrument is additionally provided with dual-blade scissors plugged into the inner cavity of the expansion tube. The minimally invasive surgery instrument for carpal tunnel syndrome is simple in structure, convenient to operate and small in surgical wounds and can cut off tendons in surgery and cut off a section of tendon, and the cut-off tendons are prevented from healing and less prone to relapsing after surgery.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, specifically a kind of carpal tunnel syndrome Minimally Invasive Surgery apparatus.
Background technology
Carpal tunnel syndrome is that modal peripheral nerve card is pressed property illness, and the reason that carpal tunnel syndrome occurs is that canalis carpi internal pressure increases and causes median nerve to be subject to card pressure.The operation method for the treatment of carpal tunnel syndrome, comprises various cutting operations, the decompression of little otch and endoscopic surgery etc.Endoscopic technique is a kind of " Wicresoft " therapeutic method of surgery, and otch is little, and wound is little, can avoid the problems such as postoperative wound discomfort.At present, use the document of various endoscopic techniques a lot, but, also have some problems, for example, iatrogenic nerve injury, the visual field is not good enough, can not distinguish anatomical variation, loosens insufficient and expense is more high.If the visual field is insufficient, should change cutting operation into.Also there are some doctors to think that little otch open decompression operation is also " less invasive techniques ", also can reduce post-operative complication rate.Endoscope " Wicresoft " carpal tunnel release operation is divided into two approaches (Chow method) and the large class of single approach (Agee method) two.Two approaches are the little otch at canalis carpi nearside and the each about 25px of incision in distally, under endoscope instructs, with little billhook incision flexor retinaculum.Single approach only cuts a little otch from canalis carpi nearside, under the guidance of endoscope, with the special cutting knife incision flexor retinaculum of loosening.No matter two approach methods or the Minimally Invasive Surgery of single approach method, be all that an incision flexor retinaculum is object, and the tendon of incision is easy to again heal, and causes recurrence.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, easy to operate, surgical wound is little, the carpal tunnel syndrome Minimally Invasive Surgery apparatus of postoperative difficult recurrence.
The present invention for the technical scheme that technical solution problem adopts is:
Carpal tunnel syndrome Minimally Invasive Surgery apparatus of the present invention comprises convergent divergent channel, for being inserted into the probe of convergent divergent channel inner chamber, the front end of described probe is with taper needle point, the front end of described convergent divergent channel is provided with dilating catheter, described dilating catheter and the coaxial setting of convergent divergent channel and equal diameters, between dilating catheter and the tube wall of convergent divergent channel, be provided with connecting plate, described connecting plate is the arc equating with the tube wall radian of convergent divergent channel, and the arc length of described arc is less than quarter turn; Separately being useful on the twolip being inserted in convergent divergent channel inner chamber cuts and comprises sword, lower sword, anterior cannula, rear sleeve, described upper sword and lower sword are all that cross section is the groove shape structure of arc, upper sword and lower sword be oppositely arranged and its both sides all with cutting edge, the extended end of upper sword and lower sword passes through together with rod hinge connection, described anterior cannula and rear sleeve are elastomeric material and make deformable tubular structure, and the extended end of described upper sword and lower sword is fixedly connected in rear sleeve.
The front end of described upper sword and lower sword is with puncture tip, and the outer surface of described rear sleeve arranges bulge loop.
The cross section of convergent divergent channel, probe is ellipse.
Owing to having adopted said structure, this carpal tunnel syndrome Minimally Invasive Surgery apparatus structure is simple, easy to operate, surgical wound is little, in operation, not only tendon can be cut off and can intercept one section of tendon, avoids the healing process of tendons of blocking, postoperative difficult recurrence.

Detailed description of the invention
Carpal tunnel syndrome Minimally Invasive Surgery apparatus of the present invention comprises convergent divergent channel 1, for being inserted into the probe 2 of convergent divergent channel 1 inner chamber.As shown in Figure 2, the front end of described probe 2 is with taper needle point.As shown in Figure 1, the front end of described convergent divergent channel 1 is provided with dilating catheter 3, described dilating catheter 3 and the coaxial setting of convergent divergent channel 1 and equal diameters, between the tube wall of dilating catheter 3 and convergent divergent channel 1, be provided with connecting plate 4, described connecting plate 4 is the arcs that equate with the tube wall radian of convergent divergent channel 1, and the arc length of described arc is less than quarter turn.As shown in Figure 5, the cross section of described convergent divergent channel 1, probe 2 is ellipse, the first step of operation, first probe 2 is inserted in a pipe 1, the taper needle point prick skin of utilizing probe 2 front ends is inserted convergent divergent channel 1 and probe 2 below diseased region flexor retinaculum, the axis of convergent divergent channel 1 is vertical with flexor retinaculum, and by connecting plate 4 be pushed to need intercept flexor retinaculum under.
As shown in Figure 3, being separately useful on the twolip being inserted in convergent divergent channel 1 inner chamber cuts and comprises sword 5, lower sword 6, anterior cannula 7, rear sleeve 8.As shown in Figure 4, described upper sword 5 and lower sword 6 are all that cross section is the groove shape structure of arc, upper sword 5 and lower sword 6 be oppositely arranged and its both sides all with cutting edge, the extended end of upper sword 5 and lower sword 6 is hinged by connecting rod 9, described anterior cannula 7 and rear sleeve 8 are elastomeric material and make deformable tubular structure, and the extended end of described upper sword 5 and lower sword 6 is fixedly connected in rear sleeve 8.The front end of described upper sword 5 and lower sword 6 is with puncture tip 10, and the outer surface of described rear sleeve 8 arranges bulge loop 11.
The second stage of operation, probe 2 is exited from convergent divergent channel 1, by the help of micro-sight glass, press flexor retinaculum, it is absorbed in the space between convergent divergent channel 1 and dilating catheter 3, then twolip is cut and inserted in convergent divergent channel 1, twolip is cut and in insertion process, is made lower sword 6 be close to the upper wall that the lower wall of convergent divergent channel 1, upper sword 5 are close to convergent divergent channel 1, the puncture tip 10 of upper sword 5 and lower sword 6 front ends punctures muscular tissue and passes from the upper and lower both sides of flexor retinaculum respectively, inserts in dilating catheter 3.The bulge loop 11 that rear sleeve 8 outer surfaces arrange, plays the effect of locating and avoiding slippage.After twolip is cut plug-in mounting and is put in place, anterior cannula 7 is sleeved on to the front end of upper sword 5 and lower sword 6, repeatedly push anterior cannula 7 and rear sleeve 8, make the relative interlock of cutting edge of sword 5 and lower sword 6 both sides, can intercept one section of flexor retinaculum, twolip is cut while exiting convergent divergent channel and the flexor retinaculum departing from can be taken out.
