As shown in Fig. 2 and Fig. 8, described scope drawing system 2 includes being arranged on moulding the exposing the elastic stayed pole 22 at endoscope operation position for tractive pathological tissues and be arranged on stayed pole 22 tail end and be easy to the tractive handle 23 that scope drawing system 2 is operated by surgical doctor of head end J-shaped that head end connects for the fixing head 21 fixed with pathological tissues and fixing head 21 temporarily.Cutting operation chamber 31 activity is set in described operating sleeve 3 and buries scope diced system 1 underground, tractive operating cavity 32 activity is set in described operating sleeve 3 and buries scope drawing system 2 underground.The action bars of described scope diced system 1 and the length of stayed pole 22 are all higher than the length of operating sleeve 3.Described scope diced system 1 can slide along cutting operation chamber 31 major axis in cutting operation chamber 31 and be exposed to outside the head end in cutting operation chamber 31 by the cutting head of scope diced system 1, and described stayed pole 22 can slide along tractive operating cavity 32 major axis in tractive operating cavity 32 and is exposed to outside the head end of tractive operating cavity 32 by stayed pole 22 head end moulding to fixing head 21 and J-shaped.Moulding stayed pole 22 head end of described J-shaped be exposed to the head end of tractive operating cavity 32 outside time stayed pole moulding property of 22J head end offset to away from direction, cutting operation chamber 31.Described stayed pole 22 at least one section of cross section is set to noncircular cross section, be also configured as the noncircular cross section mated with tractive operating cavity 32 cross section of noncircular cross section stayed pole 22 corresponding position, the length of noncircular cross section tractive operating cavity 32 is more than the length of noncircular cross section stayed pole 22.
When being embodied as, described fixing head 21 is used for and free pathological tissues edge is fixed, stress point is provided for follow-up stayed pole, make pathological tissues can turn up under the active force of stayed pole, thus the tissue site needing operation is exposed under the scope camera view such as Gastrointestinal Endoscopes, must also be in simultaneously scope diced system 1 operable within the scope of, make endoscopic surgery doctor can complete the operation that the cutting of the deep to pathological tissues is free under the monitoring of camera imaging further.
When being embodied as, described fixing head 21 and elastic stayed pole 22 are preferably wholely set, and the elastic stayed pole 22 at tractive operating cavity 32 position going out operating sleeve 3 tail end arranges tractive handle 23.Pathological tissues is turned up function to reach elastic stayed pole 22, the head end of described elastic stayed pole 22 is set to J-shaped shaping structure, and elastic stayed pole 22 head of J-shaped plasticity offsets to the direction away from scope diced system 1 after going out the tractive operating cavity 32 of operating sleeve 3 head end under the manipulation of tractive handle 23.
Concrete cutting and tractive operate and are:
1, operation scope makes the head end of scope be positioned at and anticipates the pathological tissues front preparing excision, and pathological tissues is being operated on screen by the imaging of scope imaging system.
2, this utility model is inserted insert and make operating sleeve 3 head end to expose the head opening in endoscopic technic hole by endoscopic technic hole.Promote cutting handle 13, by cutter bar 12, cutting head 11 is exposed the cutting operation chamber 31 of operating sleeve 3 head end, pathological tissues is carried out cutting near scope photographic head side and dissociates.
3, when the tissue that cutting is free has the covering effect impact free operation of cutting further to needs operating position, first retreat cutting handle 13 and make cutting head 11 be retracted in cutting operation chamber 31；Promote tractive handle 23 to make fixing head 21 expose the tractive operating cavity 32 of operating sleeve 3 head end to operating sleeve 3 head end again, fixing head 21 is directed at and needs the fixing pathological tissues dissociated that cuts to be fixed.When described fixing head 21 and free pathological tissues edge fix safe after, stayed pole 22 head end continuing to advance tractive handle 23 to make the J-shaped of suitable length moulding is exposed to outside the head end of tractive operating cavity 32, at the moulding end of J-shaped away under the direction skew active force of scope diced system 1, free pathological tissues is turned over exposes the free operating position of needs cutting further, needs the free operating position of cutting further the most clearly to image on operation screen.
4, again promote cutting handle 13, by cutter bar 12, cutting head 11 is exposed the cutting operation chamber 31 of operating sleeve 3 head end, the needs exposing imaging are cut further free operating position and cuts free operation.When free tissue is more covering may be had to affect the position that follow-up cutting is free time, appropriateness tractive handle 23 can be advanced to increase the length being exposed to moulding stayed pole 22 head end of the J-shaped of tractive operating cavity 32, making the secondary cut tissue increased that dissociates also be turned over, exposing further follow-up needs the free tissue site of cutting.
5, after all pathological tissues are cut and dissociate, tractive handle 23 is carried out back operation, the fixing head 21 making elastic stayed pole 22 head end departs from pathological tissues, this utility model can exit the handle hole of the scopes such as Gastrointestinal Endoscopes, insert hemostatic device and wound surface carries out the subsequent operations such as hemostasis.
Certainly, aforesaid operations flow process can change into as the case may be:
1, operation scope makes the head end of scope be positioned at and anticipates the pathological tissues front preparing excision, and pathological tissues is being operated on screen by the imaging of scope imaging system.
3, promoting tractive handle 23 to make fixing head 21 expose the tractive operating cavity 32 of operating sleeve 3 head end to operating sleeve 3 head end, the edge that fixing head 21 being directed at needs fixing pathological tissues to close on scope photographic head side is fixed.When described fixing head 21 fix safe after, stayed pole 22 head end continuing to advance tractive handle 23 to make the J-shaped of suitable length moulding is exposed to outside the head end of tractive operating cavity 32, offseting under active force away from the direction of scope diced system 1 at the moulding end of J-shaped, pathological tissues is pulled the tendency away from cutting part.
4, promoting cutting handle 13, cutting head 11 is exposed by cutter bar 12 the cutting operation chamber 31 of operating sleeve 3 head end, the edge that pathological tissues closes on scope photographic head side cuts free operation.At the moulding end of J-shaped away under the direction skew active force of scope diced system 1, free pathological tissues is turned over exposes the free operating position of needs cutting further, needing the free operating position of cutting further the most clearly to image on operation screen, beneficially surgical doctor cuts free pathological tissues continuously.
5, when free tissue is more covering may be had to affect the position that follow-up cutting is free time, appropriateness tractive handle 23 can be advanced to increase the length being exposed to moulding stayed pole 22 head end of the J-shaped of tractive operating cavity 32, make the tissue being complete cutting free again be turned over, expose follow-up needs further and cut free tissue site.
6, after all pathological tissues are cut and dissociate, tractive handle 23 is carried out back operation, the fixing head 21 making elastic stayed pole 22 head end departs from pathological tissues, this utility model can exit the handle hole of the scopes such as Gastrointestinal Endoscopes, insert hemostatic device and wound surface carries out the subsequent operations such as hemostasis.
Described scope diced system 1 includes T-shaped cutter, loses cutter, electric knife, and corresponding described cutting head 11 includes T-shaped jet blade, loses jet blade, electrotome head, and the tail end at scope diced system 1 can arrange to connect interface or the joint of energy source.
In order to strengthen the scope drawing system 2 tractive effect to pathological tissues when using scope diced system 1 that pathological tissues is cut, as shown in Fig. 5, Fig. 6 and Fig. 7, described stayed pole 22 at least one section of cross section is set to noncircular cross section, is also configured as the noncircular cross section mated with tractive operating cavity 32 cross section of noncircular cross section stayed pole 22 corresponding position.So it is embedded in due to the stayed pole 22 of noncircular cross section when cutting in the tractive operating cavity 32 of noncircular cross section of coupling, use scope diced system 1 that stayed pole 22 when cutting free to pathological tissues, can be avoided to rotate rolling at tractive operating cavity 32 intracavity at scope drawing system 2 tractive pathological tissues simultaneously, thus affect the scope drawing system 2 tractive effect to pathological tissues.
Noncircular cross section tractive operating cavity 32 and noncircular cross section stayed pole 22 cross section include class ellipse, class rectangle, class pentagon, but are not limited only to above profile, and principle and the effect of its stable tractive effect are essentially identical.
When only a bit of cross section is set to noncircular cross section to the tractive operating cavity 32 of described stayed pole 22 and corresponding position, the position of noncircular cross section is preferably provided at J-shaped moulding stayed pole 22 head or closes on the position of head.When using scope drawing system 2 to pathological tissues tractive, really play tractive effect is moulding stayed pole 22 head of J-shaped or the position closing on head, and stability herein is closed important especially.Simultaneously, the length of noncircular cross section tractive operating cavity 32 need to be more than the length of noncircular cross section stayed pole 22, so when moulding stayed pole 22 head of whole J-shaped or close on the position of head be completely used for tractive pathological tissues time, the noncircular cross section of follow-up position stayed pole 22 remains in the noncircular cross section tractive operating cavity 32 of coupling, and tractive effect is played stablizing effect.
In order to reduce frictional force when described scope drawing system 2 uses, it is coated with hydrophilic coating at described tractive operating cavity 32 inwall or stayed pole 22 outer wall, described tractive operating cavity 32 is done before using humidifying process, the hydrophilic coating of humidifying can reduce the coefficient of friction between described tractive operating cavity 32 inwall and stayed pole 22 outer wall to greatest extent, thus reduces frictional force.
In like manner, in order to reduce frictional force when described scope diced system 1 uses, action bars outer wall at described cutting operation chamber 31 inwall or scope diced system 1 is coated with hydrophilic coating, described cutting operation chamber 31 is done before using humidifying process, the hydrophilic coating of humidifying can reduce the coefficient of friction between described cutting operation chamber 31 inwall and the action bars outer wall of scope diced system 1 to greatest extent, thus reduces frictional force.
Shown in as shown in Figure 2, Figure 3 and Figure 4, described fixing head 21 includes the small tip being provided with small agnail.In this embodiment, the moulding head end of J-shaped at described elastic stayed pole 22 is arranged like sharp-pointed pin head-like structure, arranges some small agnails at tip trailing edge.When needs use this structure to carry out tractive, first the prong structure of described elastic stayed pole 22 is together elapsed out tractive operating cavity 32 together with small agnail, then this prong structure together being thrust together with small agnail in needing fixing pathological tissues, now, pathological tissues is fixed.Need only to need to continue the J-shaped head end of elastic stayed pole 22 moulding for J-shaped is elapsed out tractive operating cavity 32 during tractive, under the elastic acting force of the moulding elastic stayed pole 22 of J-shaped; pathological tissues can be pulled suspention, thus expose and need to continue the pathological tissues position that cutting is free.
In order to avoid this small tip pierces through gastrointestinal wall when thrusting pathological tissues, the length of small tip should be set smaller than the thickness of gastrointestinal wall, can add stop cross bar in the rear end of small tip simultaneously, thus avoid this small tip to thrust gastrointestinal wall to greatest extent and cross and take an advanced study into perforation complication.When pathological tissues cutting has dissociated, when needing to separate small tip with pathological tissues, it is only necessary to the elastic stayed pole 22 in strength retraction tractive operating cavity 32.Now, pathological tissues is damaged the operation to patient and surgical doctor and is obstruction by small agnail.
As can be seen from figures 8 and 9, described fixing head 21 includes that horn-like suction nozzle, described stayed pole 22 correspondingly are set to elastic sucker, and is exposed to the tail end of tractive operating cavity 32 at stayed pole 22 and arranges negative port.In this embodiment, when needs use this structure to carry out tractive, first the horn-like suction nozzle of the elastic stayed pole 22 of described elastic sucker structure is elapsed out tractive operating cavity 32, then it is close to this horn-like suction nozzle need fixing pathological tissues surface, again elastic stayed pole 22 tail end of elastic sucker structure being connected negative pressure, under the effect of negative pressure, the absorption tightly of the horn-like suction nozzle of stayed pole 22 is on pathological tissues surface.Need only to need to continue the J-shaped head end of elastic stayed pole 22 moulding for J-shaped is elapsed out tractive operating cavity 32 during tractive, under the elastic acting force of the moulding elastic stayed pole 22 of J-shaped; pathological tissues can be pulled suspention, thus expose and need to continue the pathological tissues position that cutting is free.The advantage of this embodiment is to tissue not damaged, but its shortcoming is the most fairly obvious, when the elastic stayed pole 22 of elastic sucker structure blocks, the negative pressure pressure connected at elastic stayed pole 22 tail end of elastic sucker structure cannot be communicated to horn-like suction nozzle, fixes and unsuccessfully causes ensureing tractive suspension effectiveness.
As shown in Figure 10, described tractive operating cavity 32 exit site arranges tractive fixing device 24, for stayed pole 22 and operating sleeve 3 being fixed temporarily.Described tractive fixing device 24 is for by the interim exit site that stayed pole 22 is temporarily fixed at operating sleeve 3, make scope drawing system 2 relatively reliable to cutting when free pathological tissues tractive suspends in midair, bigger skew will not occur, it is simple to operator feels at ease to use scope diced system 1 to proceed the free operation of cutting at position deeper to pathological tissues.When tractive suspension effectiveness is unsatisfied with, only need to unclamp tractive fixing device 24, again adjusting stayed pole 22 increases and exposes the length that the J-shaped of tractive operating cavity 32 is moulding, can increase suspention height, strengthen suspension effectiveness.Then reuse tractive fixing device 24 and stayed pole 22 is temporarily fixed at the exit site of operating sleeve 3, reuse scope diced system 1 and proceed the free operation of cutting at position deeper to pathological tissues.
Tractive fixing device 24 has numerous embodiments, as shown in Figures 10 and 11, uses a kind of relatively simple embodiment for this utility model.That is: described tractive fixing device 24 includes being arranged on soft card cylinder 25 that tractive operating cavity 32 exit site connects with tractive operating cavity 32 and is nested with the non-closed annular collar 26 at soft card cylinder 25 outer wall.The activity of described stayed pole 22 is nested with at soft card cylinder 25 intracavity.The non-closed end opposite face of described annular collar 26 correspondence is respectively provided with the latch 27 of coupling, and the stayed pole 22 being nested with in interim fixing soft card cylinder 25 can be fixed by the non-closed end of described annular collar 26 correspondence by latch 27 temporarily.
Soft card cylinder 25 is connected to tractive operating cavity 32 exit site, and described soft card cylinder 25 barrel chamber is fixing with the inner chamber of tractive operating cavity 32 to be connected, and stayed pole 22 activity is nested with in soft card cylinder 25 barrel chamber inner chamber with tractive operating cavity 32.Described soft card cylinder 25 arranges depression in the middle part of barrel, two ends arrange annular lug, described non-closed annular collar 26 is set in the ring-shaped depression in the middle part of soft card cylinder 25, non-closed annular collar 26 be integrally formed cross section more than a full circle hold structure, the non-closed end opposite face at non-closed annular collar 26 is respectively provided with the latch 27 of coupling.When stayed pole 22 is fixed by needs temporarily, the coupling latch 27 that operation non-closed annular collar 26 makes its non-closed end opposite face arrange slides relatively, the annular ring making non-closed annular collar 26 tightens up, make annular ring tighten up effect by the latch 27 of non-closed end ectonexine surface configuration coupling can not retreat, and then strengthen soft card cylinder 25 outer surface in being arranged on non-closed annular collar 26 class annular ring is oppressed, finally make soft card cylinder 25 inner surface that the compressing of stayed pole 22 is strengthened by the deformation of soft card cylinder 25, reach to be temporarily fixed at stayed pole 22 purpose of the exit site of operating sleeve 3.
Need to get loose stayed pole 22 time, it is only necessary to by the latch 27 of non-closed annular collar 26 non-closed end outer layer along the parallel passage of long axis direction of stayed pole 22, make the latch 27 of non-closed end outer layer depart from the fixed relationship of latch 27 latch of non-closed end internal layer.Under the elastic reaction of non-closed annular collar 26 self, the class annular ring of non-closed annular collar 26 becomes big, soft card cylinder 25 pressure in the class annular ring being arranged on non-closed annular collar 26 is reduced, i.e. can reach the purpose of stayed pole 22 in tractive operating cavity 32 inner chamber that gets loose.
In a word: this utility model simple in construction, when the endoscopic surgery cuttings such as gastrointestinal dissociate bigger pathological tissues, can carry out suspending tractive in midair to pathological tissues by the scope drawing system 2 being arranged in operating sleeve 3, fully expose endoscopic surgery and need the position of operation, improve procedure efficiency, increase operation safety.Simple in construction, with low cost, it is worth at clinical expansion.
