Abstract
The present invention relates to a kind of medical apparatus and instruments, specifically a kind of carpal tunnel syndrome Minimally Invasive Surgery apparatus.Including expansion pipe, for being inserted into the probe in expansion tube cavity, being provided with connecting plate between the tube wall of dilating catheter and expansion pipe, described connecting plate is the arc equal with the tube wall radian of expansion pipe, and the arc length of described arc is less than quarter turn；Separately have and cut for the twolip being inserted in expansion tube cavity.Carpal tunnel syndrome Minimally Invasive Surgery apparatus structure is simple, easy to operate, surgical wound is little for this, is possible not only to cut off by tendon and can intercept one section of tendon, it is to avoid the healing process of tendons blocked, postoperative not easily recurs in operation.
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 modal Peripheral nerve compression illness, the reason that carpal tunnel syndrome occurs, and is that wrist overpressure increases and causes that median nerve is subject to card to press.The operation method for the treatment of carpal tunnel syndrome, including 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, it is possible to avoid the problems such as postoperative wound discomfort.At present, the document using various endoscopic technique is a lot, but, there is also some problems, for instance, iatrogenic nerve injury, the visual field is not good enough, it is impossible to distinguish anatomical variation, loosens insufficient and costly etc..If the visual field is insufficient, cutting operation should be changed into.Also the operation of little otch open decompression is also " less invasive techniques " to have some doctors then to think, it is also possible to reduce post-operative complication rate.The operation of endoscope " Wicresoft " carpal tunnel release is divided into double; two approach (Chow method) and single approach (Agee method) two big class.Double; two approaches are the little otch respectively cutting an about 25px at canalis carpi nearside and distally, under endoscope direction, cut flexor retinaculum with little billhook.Single approach then only cuts a little otch from canalis carpi nearside, under the guidance of endoscope, cuts, with special cutting knife, flexor retinaculum of loosening.No matter the Minimally Invasive Surgery of double; two approach methods or single approach method, is all for the purpose of an incision flexor retinaculum, and the tendon of incision is easy to again heal, and causes recurrence.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, easy to operate, surgical wound is little, the postoperative carpal tunnel syndrome Minimally Invasive Surgery apparatus not easily recurred.
The present invention solves that technical problem be the technical scheme is that
Carpal tunnel syndrome Minimally Invasive Surgery apparatus of the present invention include expansion pipe, for be inserted into expansion tube cavity in probe, the front end of described probe is with taper needle point, the front end of described expansion pipe is provided with dilating catheter, described dilating catheter is coaxially disposed and equal diameters with expansion pipe, it is provided with connecting plate between the tube wall of dilating catheter and expansion pipe, described connecting plate is the arc equal with the tube wall radian of expansion pipe, and the arc length of described arc is less than quarter turn；Separately have to cut for the twolip being inserted in expansion tube cavity and include upper sword, lower sword, anterior cannula, rear sleeve, described upper sword and lower sword are all cross sections is the groove-like structure of arc, upper sword and lower sword are oppositely arranged and its both sides are all with cutting edge, together with upper sword passes through rod hinge connection with the extended end of lower sword, 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.
Expansion is managed, the cross section of probe is ellipse.
Owing to have employed said structure, carpal tunnel syndrome Minimally Invasive Surgery apparatus structure is simple, easy to operate, surgical wound is little for this, is possible not only to cut off by tendon and can intercept one section of tendon, it is to avoid the healing process of tendons blocked, postoperative not easily recurs in operation.

Detailed description of the invention
Carpal tunnel syndrome Minimally Invasive Surgery apparatus of the present invention include expansion pipe 1, for be inserted into expansion pipe 1 inner chamber in probe 2.As in figure 2 it is shown, the front end of described probe 2 is with taper needle point.As shown in Figure 1, the front end of described expansion pipe 1 is provided with dilating catheter 3, described dilating catheter 3 is coaxially disposed and equal diameters with expansion pipe 1, it is provided with connecting plate 4 between the tube wall of dilating catheter 3 and expansion pipe 1, described connecting plate 4 is the arc equal with the tube wall radian of expansion pipe 1, and the arc length of described arc is less than quarter turn.As shown in Figure 5, described expansion pipe 1, probe 2 cross section be ellipse, the first step of operation, first probe 2 is inserted in a pipe 1, the taper needle point utilizing probe 2 front end punctures skin and inserts below diseased region flexor retinaculum by expansion pipe 1 and probe 2, the axis of expansion pipe 1 is vertical with flexor retinaculum, and connecting plate 4 is pushed to the underface of the flexor retinaculum needing intercepting.
Upper sword 5, lower sword 6, anterior cannula 7, rear sleeve 8 is included as it is shown on figure 3, separately have to cut for the twolip being inserted in expansion pipe 1 inner chamber.As shown in Figure 4, described upper sword 5 and lower sword 6 are all cross sections is the groove-like structure of arc, upper sword 5 and lower sword 6 are oppositely arranged and its both sides are 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 expansion pipe 1, help by micro-sight glass, pressing flexor retinaculum, making it be absorbed in the space between expansion pipe 1 and dilating catheter 3, then cut by twolip in insertion expansion pipe 1, twolip is cut makes lower sword 6 be close to the expansion lower wall of pipe 1 in insertion process, upper sword 5 is close to the upper wall expanding pipe 1, the puncture tip 10 of upper sword 5 and lower sword 6 front end punctures muscular tissue respectively from the upper and lower both sides traverse of flexor retinaculum, inserts in dilating catheter 3.The bulge loop 11 that rear sleeve 8 outer surface is arranged, plays location and avoids the effect slipped.Twolip is cut after plug-in mounting puts in place, anterior cannula 7 is sleeved on the front end of upper sword 5 and lower sword 6, and repeatedly extruding anterior cannula 7 and rear sleeve 8, make sword 5 and the cutting edge articulate relative of lower sword 6 both sides, can intercepting one section of flexor retinaculum, twolip is cut the flexor retinaculum that can will be disengaged from when exiting expansion pipe and is taken out.
