Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of fixable laparoscope puncture outfit.
Background technology
Laparoscopic surgery clinically at present carries out the Minimally Invasive Surgery mode be most widely used.Laparoscope puncture outfit is used to sting human body body wall (position such as breast, abdomen, waist) through skin in operation, by the sheath pipe front end indwelling of perforator in the body cavitys such as abdominal cavity, thoracic cavity or pneumoretroperitoneum, then by the passage implantation surgery apparatus in puncture sheath pipe, corresponding operation technique is carried out to above-mentioned endoceliac histoorgan.Laparoscope puncture outfit is the apparatus that must use in this operation, and existing laparoscope puncture outfit sheath pipe thrusts without effective fixture after body cavity, and situation that is external and that go deep in body often appears deviating from puncture sheath pipe in operation process.Perforator sheath pipe was inserted damage internal organs risk deeply, the mirror visual field, chamber can be caused to be blocked and make surgical instrument operation difficulty, as all kinds of pincers, folder, ultrasonic cutter head and needle holder etc. cannot be opened; Perforator sheath pipe frequently deviates to make patient's repeated puncture of having to place sleeve pipe, has a strong impact on operation progress and quality and making patients's wound.In addition, need in laparoscopic surgery to be filled with carbon dioxide in body cavity, body cavity is expanded so that surgical instrument operation.Owing to can there is larger gap between the perforator sheath pipe that uses at present and body wall puncture channel, this easily causes intracavity gas to leak.Gas leaks outside in a large number and body cavity decompression can be made to subside, severe jamming operation technique; Excessive gas enters sub-surface porosity fatty tissue gap also can form extensive subcutaneous emphysema, adds the misery of patient.
The maximum perforator sheath pipe fixation of current clinical practice is suture line of skin method, namely by after site of puncture suture line of skin by line through after the side opening that perforator tube wall is preset by suture knotting thus the method making perforator sheath pipe fixing.This fixed form is simple and convenient, can conscientiously prevent sheath pipe from deviating from, but cannot solve the problem that dark gentle external leakage inserted by sheath pipe.Lack for laparoscopic surgery perforator used the present situation improving fixation, different researcher devises multiple perforator auxiliary fixing structure or the device with fixation.As the CN204428128U patent of Patent Office of the People's Republic of China's bulletin on July 1st, 2015, the gum elastic fixed disk of its design can be placed on outside perforator sheath pipe, utilize the elastic tightening effect of elastomeric material to make dish relative with sheath pipe fixing during use, and try to get to the heart of a matter and to be fixed by suture with human body body wall puncture place skin.Adopt No. CN203915028U of bulletin in Patent Office of the People's Republic of China on November 5th, 2014 of similar this external fixation with to wait in Patent design that then to realize between perforator sheath Guan Yuqi external fixer with bolt relative fixing on May 27th, 2015 No. CN103230303B of bulletin.The design of this external fixation can be played and necessarily prevent perforator sheath pipe from inserting effect that is dark and/or that deviate from, but perforator sheath pipe is repeatedly by reversing and push-pull effort effect in actual operation operation, the fixture of sheath Guan Yuqi overcoat still has the larger risk that gets loose, and outer sleeve fixture mechanism must limit perforator sheath pipe rotational angle to a certain extent, disturb surgical instrument operation, this at relatively far-reaching narrow and small body cavity as particularly remarkable during pneumoretroperitoneum instrumentation.In addition, in the CN204581447U Patent design of Patent Office of the People's Republic of China's bulletin on August 26th, 2015, an air bag is set in periphery, perforator sheath pipe front end, it is made to fill by pipeline reserved in sheath tube wall to being positioned at endoceliac air bag water filling during use, thus prevent perforator sheath pipe to deviate from and possess certain anti-gas-leak effect, but such body internal fixation method can not prevent perforator sheath pipe from inserting dark.Then air bag is provided with in perforator sheath pipe body front end, middle part, rear end in the CN203736281U Patent design of Patent Office of the People's Republic of China's bulletin on July 30th, 2014, during use, frontal air bag is positioned at body cavity, middle part air bag is positioned at body wall puncture channel, and rear end air bag is positioned external.The fixation of such three air bags in inside and outside can make that perforator sheath pipe is conscientiously fixing cannot displacement, but multiple airbag design of perforator sheath pipe obviously reduce sheath pipe reality effectively uses length, even make it cannot penetrate body wall and insert body cavity, the mode that inside and outside is all fixed also limits the rotational angle of sheath pipe more, in body cavity, the too small sheath pipe that cannot prevent of air bag is shifted, excessive, can surgical field of view be disturbed, and the air bag in the middle part of sheath pipe also may tear body wall muscular tissue increase the weight of hemorrhage and damage.Similar design also sees the patents such as No. CN203169273U of Patent Office of the People's Republic of China's JIUYUE in 2013 bulletin on the 4th.Therefore existing perforator fixture design existence fully can not fix perforator sheath pipe, limit sheath pipe rotational angle, decrease sheath pipe real work length, do not possess anti-gas-leak function or have defects such as increasing the weight of body wall puncture channel damage risk, all can not be satisfied with and solve laparoscope puncture outfit sheath pipe fixation problem, be necessary to continue to be improved.

Detailed description of the invention
As shown in Figure 1, the invention provides a kind of fixable laparoscope puncture outfit, it syndeton 3 comprising sheath pipe 1, fixed structure 2 and be connected described sheath pipe 1 and described fixed structure 2, along the axial direction of described sheath pipe 1, described fixed structure 2 can be fixed by described syndeton or move on described sheath pipe 1;
Described fixed structure 2 specifically comprises stationary pipes 21, air bag 22, note liquid/gas passage (omitting in figure) and fluid injection/air valve 23; Described stationary pipes 21 is sheathed on outside described sheath pipe 1, and length is less than described sheath pipe 1; The front end of described stationary pipes 21 is located at by described air bag 22; Described fluid injection/air valve 23 is provided with the rear end of described stationary pipes 21, and the valve port of described fluid injection/air valve 23 protrudes from outside the tube wall of described stationary pipes 21, and the length outside the tube wall that wherein said fluid injection/air valve 23 protrudes from described stationary pipes 21 is preferably 1.0cm; Described air bag 22 and described fluid injection/air valve 23 are by described note liquid/gas channel connection, and described note liquid/gas passage is located on the tube wall of described stationary pipes 21.
Perforator is in the process used, described stationary pipes 21 can move in puncture channel along the axial direction of described sheath pipe 1, stop when the described air bag 22 of described stationary pipes 21 front end is inserted in subcutaneous layer of fat II mobile, make described sheath pipe 1 relative fixing with described both stationary pipes 21 position by described syndeton 3.Now described air bag 22 is positioned in the subcutaneous layer of fat II in human body body wall puncture channel, namely between the relatively fine and close Musclar layer III of body wall tissue and skin layer I.By the valve port of described fluid injection/air valve 23 by described note liquid/gas passage, liquid can be injected or gas makes it fill in described air bag 22.Described air bag 22 is the preparation such as medical grade silicon rubber or PVC material, and its hot strength is large, can bear hydraulic pressure or air pressure in described air bag 22 completely, and described air bag 22 not easily breaks under external force.The valve port of described fluid injection/air valve 23 protrudes from outside the tube wall of described stationary pipes 21, and when perforator uses, described fluid injection/air valve 23 is positioned at external, has the effect stoping described stationary pipes 21 excessively to go deep into puncture channel.By full described air bag 22 and protrude from described stationary pipes 21 tube wall outside described fluid injection/air valve 23, the perforator in using is fixed.
Adopt said structure, described air bag 22 is positioned to make sheath pipe 1 fixed effect definite in sub-surface porosity fatty tissue.According to skin mechanics characteristic, fine and close dermal tissue has the little feature of the large ductility of comprcssive strength, can effectively stop air bag 22 to deviate from external from skin penetrating incision, and then plays and prevent sheath pipe 1 from deviating from effect.Body wall Musclar layer III is organized comprcssive strength large but is had certain ductility, under the effect of routine operation strength, it can effectively stop air bag 22 to shift forward, thus stop described sheath pipe 1 to go deep into body cavity IV, if but only have the design of air bag 22, when pushing away effect before moment violence, air bag 22 originally may embed Musclar layer III puncture channel and cause muscle tear hemorrhage, there is anterior displacement in sheath pipe 1 simultaneously, therefore in the present invention, the rear end of described stationary pipes 21 is provided with described fluid injection/air valve 23, and the valve port of described fluid injection/air valve 23 protrudes from outside the tube wall of described stationary pipes 21, this kind of design perforator is in the process used, the valve port of described fluid injection/air valve 23 is positioned at outside body wall skin just, described stationary pipes 21 and described air bag 22 effectively can be stoped excessively to move forward and to go deep into puncture channel, the double cutting off inflow effect of the valve port of described air bag 22 and described fluid injection/air valve 23 prevents sheath pipe 1 to go deep into body cavity IV conscientiously, because described air bag 22 elastic reaction makes sheath pipe 1 recover original ideal position after current thrust disappears.
Described air bag 22 can effectively prevent gas in body cavity IV from being formed through slot leakage and subcutaneous emphysema between puncture channel and described sheath pipe 1.Due to described air bag 22 full after be arranged in subcutaneus adipose tissue, it can pass the gap between extruding periphery fatty tissue filling Musclar layer III puncture channel and described sheath pipe 1, described air bag 22 is fitted closely with surrounding tissue simultaneously, gas is effectively prevented to leak to fat deposit II, the squeezing action of described air bag 22 also makes peripheral adipose tissue more fine and close, wherein interstice disappears, and gas cannot excessively spread into subcutaneous space, so prevent subcutaneous emphysema to be formed.
Described air bag 22 obviously can not reduce described sheath pipe 1 active length and limit its rotational angle.Because described air bag 22 is positioned at body wall puncture channel, instead of body cavity IV is interior or external, so can not reduce described sheath pipe 1 effectively use length.Because air bag 22 described in single elasticity is positioned at the soft and loose subcutaneous layer of fat II of body wall, aspect between relatively fine and close Musclar layer III and skin layer I there is larger mobile space, thus it can not produce interference to the rotation of described sheath pipe 1, can not limit sheath pipe 1 rotational angle.
Described air bag 22 can not increase the weight of puncture channel damage.Owing to being positioned in the subcutaneous layer of fat II that loosens, described air bag 22 is little and power active area large and disperse to peripheral adipose tissue extruding force when suitably full, can not tear fatty tissue.Described in actual operation operation, sheath pipe 1 can not stop dynamic, and this makes the pressure of the periphery fatty tissue in described air bag 22 pairs of certain limits cut in and out, and there will not be due to the air bag 22 lasting situation of oppressing fatty tissue and causing its ischemic necrosis for a long time.Due to powerful resistance to compression and the resiliency characteristics of skin histology, even if there is the situation of air bag 22 described in the outside tractive of violence once in a while, also can not there is skin and be separated with tearing of subcutaneous layer of fat II.When inserting described stationary pipes 21, comparatively conventional cut is slightly large for required skin penetrating otch, but this not obvious damage endoscope-assistant surgery invasive.In actual operation, the diameter of puncture channel skin incision much larger than stationary pipes 21 described in the present invention of the displacement of sheath pipe 1 and Leakage Gas the most easily occurs, and therefore described stationary pipes 21 of the present invention can be inserted subcutaneous easily, does not need to expand skin incision.
Described syndeton 3 comprises the first syndeton 31 and the second syndeton 32 cooperatively interacted, and described first syndeton 31 is located on the outer wall of described sheath pipe 1, and described second syndeton 32 is located on the inwall of described stationary pipes 21.
The invention provides the syndeton 3 of two kinds of modes, wherein a kind of syndeton 3 is as shown in one of Fig. 2-5, is annular band.Standing on the sheath pipe 1 considering existing perforator have annular band, in order to can existing resource be made full use of, by annular band changes groove 311 structure can with described stationary pipes 21 with the use of, and described stationary pipes 21 conveniently can be inserted in described sheath pipe 1 rear end and running fix and easy to use.When described syndeton 3 is annular band, groove 311 is axially arranged with along described sheath pipe 1 in described first syndeton 31, the length of described groove 311 is greater than the length of described second syndeton 32, the vertical section of described groove 311 is identical with the shape of the vertical section of described second syndeton 32, and in same upright plane, described first syndeton 31 and described second syndeton 32 can form approximate complete annular band.When the described groove 311 in described first syndeton 31 forms approximate complete annular band with described second syndeton 32 in same upright plane, described groove 311 is equivalent to for described second syndeton 32 provides the passage of slip, and described stationary pipes 21 can realize relative sliding with described sheath pipe 1 in the axial direction along described groove 311; When the described groove 311 in described first syndeton 31 can not form approximate complete annular band with described second syndeton 32 in same upright plane, namely when described first syndeton 31 is chimeric state with described second syndeton 32, described stationary pipes 21 can not be slided along described sheath pipe 1 in its axial direction, and namely described stationary pipes 21 is relative fixing with described sheath pipe 1.The length of described groove 311 is greater than the length of described second syndeton 32, therefore described second syndeton 32 both can overlap with the described groove 311 in described first syndeton 31 and relative sliding and not offseting, again can described sheath pipe 1 for axle rotates described stationary pipes 21, make described second syndeton 32 and described first syndeton 31 overlapped chimeric, thus make described sheath pipe 1 and described stationary pipes 21 in the axial direction relative position fix, and fixed effect is definite.Because described stationary pipes 21 need be slided along described groove 311 rapid and convenient, therefore be matched in clearance between the outer wall of described second syndeton 32 and the inwall of described groove 311, namely in same upright plane, described first syndeton 31 and described second syndeton 32 can form approximate complete annular, instead of complete annular.
The another kind of structure of described syndeton 3, as shown in one of Fig. 6-8, is continuous print helical thread.Described first syndeton 31 and described second syndeton 32 are continuous print helical thread, and both can be fitted together to mutually, rotate by described sheath pipe 1 is relative with described stationary pipes 21 during use, both described sheath pipe 1 and described stationary pipes 21 position is made to move and arrive ideal position, now stop relatively rotating, namely described sheath pipe 1 and described stationary pipes 21 relative position are fixed.The present invention is using continuous print helical thread as described syndeton 3, and structure is simple, and convenient operation uses, and faster can realize fixing or moving between described sheath pipe 1 and described fixed structure 2.
The described stationary pipes 21 of the present invention's design and described syndeton 3, structure is simple, and operating procedure is few, easy to use.Due to different from the fixation principle of the perforator sheath pipe of Patent design before this, loaded down with trivial details on sheath pipe 1 described in existing perforator the structure such as air bag, waterflood path need not be set, therefore greatly reduce preparation difficulty and saved resource.Described stationary pipes 21 designs with the split of described sheath pipe 1, makes user can select independent assortment flexibly according to practical situation, very convenient clinical practice.
The invention provides described sheath pipe 1, dimensions that described stationary pipes 21 is different with described air bag 22, wherein said stationary pipes 21 need are designed to two or three diameter specifications matched with the perforator sheath pipe 1 of current wide clinical application.
The active length of described sheath pipe 1 is 10cm, and overall diameter is 5-12mm.In order to match with sheath pipe 1 specification standards of existing perforator, make full use of existing resource, the overall diameter of described sheath pipe 1 is preferably designed to 5mm, 10mm and 12mm tri-kinds of specifications, but can be designed to other specifications according to concrete needs.
The length of described stationary pipes 21 is 2-5cm, and the thickness of tube wall is 1.5mm, and overall diameter is 8-15mm.Consider that routine clinical site of puncture is human body body wall subcutaneous layer of fat II thicker part, and skin thickness is generally no more than 1.0cm, in the process of the therefore actual use of the present invention, according to subcutaneous layer of fat II thickness of the different body wall site of puncture of different patient, the dimensions of described stationary pipes 21 can be designed specifically to: the length of described stationary pipes 21 is respectively 3cm and 5cm two kinds of specifications, and the overall diameter of described stationary pipes 21 is respectively 8mm, 13mm and 15mm tri-kinds of specifications.
