Technical field

This disclosure relates to for removing tissue from body passage, such as remove Atherosclerosis from artery using rotary cutting apparatus Change the apparatus and method of patch.Specifically, this disclosure relates to the improvement of the rotary cutting apparatus with replaceable drive shaft.

Background technology

Work out in multiple technologies and device of the artery with removal or repair tissue in similar body passage. This technology and the general object of device are to remove the atherosclerotic plaque in patient's artery.Artery sclerosis is characterised by Fat deposition (sebaceous cyst) in the theca interna (that is, in subendothelial face) of patient vessel.Generally pass through over time, embryo deposit To be relatively soft, the atheromatous material hardening rich in cholesterol is into calcified plaque.This atheroma limits blood The flowing of liquid, and be thus commonly referred to as Stenotic pathologic change or restenosis, barrier material is referred to as stenotic material.If Do not treat, then this is narrow to be likely to result in angina pectoris, hypertension, myocardial infarction, apoplexy etc..

Several some or all of rotary cutting apparatus for being used to attempt stenotic material are developed.It is all in a kind of device Such as in United States Patent (USP) No.4, show, performed in the far-end of flexible rotatable drive shaft covered with all in 990,134 (Auth) Such as the rotary drilling of the abrasiveness cutting material of diamond abrasive (diamond particles or bortz powder).

United States Patent (USP) No.5,314,438 (Shturman) show another rotary cutting apparatus with rotatable drive shaft, A part for drive shaft has the diameter of increase, and at least one section of the diameter portion of this increase covers with grinding-material to limit drive The ground section of moving axis.When rotated at high speed, means of abrasion can remove stenotic tissue from artery.

United States Patent (USP) No.5,314,407 (Auth) show can with Auth 134 and Shturman 438 patents The details for the handle types that the rotary cutting apparatus of the type shown is used in combination.The handle of type is shown in Auth 407 patents By HeartTechnology, Inc. (Redmond, Wash.) commercializations, now by trade mark Redmond, Wash.) under Boston Scientific Corporation (Natick, Mass.) institute of rotary cutting apparatus for selling Have.The handle of device include multiple parts, including compressed gas-driven turbine, for clamp extend through Drive shaft, the mechanism of the guide line of the part of optic fiber tachometer and the pump for salt solution pumping to be passed through into drive shaft.

The connection of drive shaft (there is its correlation to bore) between turbine in device makes permanent；However, Normally need the brill using more than one gear in rotary-cut surgical procedure.That is, generally first by reduced size brill with Narrow is set to be opened to certain diameter, and then using the brill of one or more large-sizes further to open narrow. Subsequent larger-diameter multiple brills it is this using sometimes referred to as " stepping technique " and byThe manufacture of device Business recommends.In many brill technologies, it is necessary to using newDevice for each such a continuous size brill.Cause This is, it is necessary to can allow surgeon to remove work through whole operation using only a handle and by appropriate drive shaft with tissue Tool (for example, bore) is attached to the biopsy system of this handle, with start operation and then by drive shaft and Tissue removal tools more It is changed to different sizes or the even drive shaft of the Tissue removal tools of different designs.

Subsequent version have been incorporated into and be replaced by the flexible distal portion of drive shaft with not together with brill The ability of another distal portions of the drive shaft bored with size.The ins and outs of this system " can connect drive included in entitled Moving axis system " and issued on June 16th, 1998 in Wulfman United States Patent (USP) No.5,766,190.This system utilizes soft Property drive shaft, the replaceable distal end that this flexible drive shaft has connection/disconnecting feature to allow surgeon to make flexible drive shaft Part is disconnected together with brill from the flexible proximal end part of the drive shaft for the turbine for being connected to handle, thus allows brill size to set It is calculated as being changed in the case where not abandoning whole patch excision units.Each commutative drive shaft section is all disposed within it certainly In the replaceable guide casing and catheter body of body.The flexible proximal end part of drive shaft is permanently attached to turbine simultaneously in such a system And be changed without.This system is existed by Boston ScientificTrade (brand) name under be commercialized.To the greatest extent PipeAllow someone to change brill size, but require actually to make the exchangeable portion disjunction of drive shaft open company Connect and with another replaceable partial replacement of drive shaft it the step of it is extremely complex, and operate with requiring opposite fine non- Often small part.

First, catheter body must be disconnected with handle, and include breaking with exposure to distal end is mobile away from handle The proximal part of the flexible drive shaft of the coupling connect and the part of distal portions.By to distal end slide lock fixed tube, it is allowed to soft Interlockable teeth on the proximal part and distal portions of property drive shaft is disengaged from each other, and disconnects this coupling.Then have The similar flexible distal drive shaft section that difference is bored may be coupled to the flexible proximal end part of drive shaft.To complete this assembling, Locking teeth on the near-end that part is replaced in the distal end of drive shaft first must be with the far-end of the proximal part in drive shaft Interlockable teeth is aligned longitudinally and rotatably.Because soft drive shaft diameter is typically less than 1mm, therefore the size of locking teeth is same It is very small, it is necessary to effective manual dexterity with visual acuity to be appropriately aligned locking teeth and interlock locking teeth.Once locking Tooth suitably mutually locking each other, then locking pipe proximally slides to fix this coupling (also with very small diameter).So Rear tube housing is necessarily connected to handle housing.

Although this system, which allows someone that a kind of size is bored into (together with a part for drive shaft), is replaced by another size Bore, but this replacing program is not simple and quite must carefully performed.The individual for performing replacing program must be so Do, while the element for wearing surgical gloves to protect the personal blood away from patient and keep system is sterile.Surgery hand Art gloves reduce the personal tactile sensation for performing replacing program, and so that this replacing program is more difficult.

In recent years, exploitation is made efforts to easily attachment and/or drive shaft and tissue removal apparatus is changed Rotary cutting apparatus.

For example, United States Patent (USP) No.6,024,749 (Shturman etc.) that all entirety is incorporated herein by reference, 6,077,282 (Shturman etc.), 6,129,734 (Shturman etc.) and 6,852,118 (Shturman etc.), which are disclosed, to be had The rotary cutting apparatus of replaceable driving axle casing, this replaceable driving axle casing includes removedly could attach to the handle housing of device Housing.Replaceable cartridge includes being removably attached to the longitudinally movable pipe of prime mover support and removedly could attach to former dynamic The rotatable drive shaft of machine.Provided with coupler, longitudinally extendable pipe is connected to prime mover by the coupler, while indicating that longitudinal direction can The relative position of extension and the proximal part of drive shaft.The U.S. Patent Publication No.2011/ being hereby incorporated 0087254 (Welty) discloses rotary cutting apparatus, and its prime mover has prime mover coupler, and drive shaft is with dynamic with original The pieceable drive shaft coupler of machine coupler.Drive shaft coupler has complementary and geometrically keyed in prime mover coupler To mutual engageable lateral cross section.When drive shaft coupler and prime mover coupler are joined to each other, this complementation is transversal Face allows the axial translation between drive shaft coupler and prime mover coupler, while suppressing in drive shaft coupler and prime mover Rotary coupler between coupler.

U.S. Patent Publication No.2011/0077673 (Grubac etc.) other rotary cutting apparatus, using drive shaft with Magnetic clutch connection between prime mover.Drive shaft and prime mover pass through the magnetic attracting force between motor plate and driving axillare Longitudinally keep together.Torque between motor and drive shaft fully between motor plate and driving axillare transmission also, When below threshold torque, together with motor plate and driving axillare continue to be rotationally retained at by static friction.When motor is with driving When torque between moving axis is more than threshold torque, motor plate rotatably slides past each other with driving axillare, causes in motor Surplus torque is transmitted between drive shaft.

Although devices above using friction or magnetic couplings removedly to engage drive shaft and prime mover, some Rotary cutting apparatus has the drive shaft that the gear by a pair of matchings drives, and a gear is connected to drive shaft and a gear connects It is connected to the gear of matching.Due to this transmission arrangments, rotary cutting apparatus is normally limited to each one shaft size of component.Do not replace generally The gear of drive shaft is connected to, therefore the size of any replaceable drive shaft all must be designed to suitably engage with drive shaft. Therefore, it is necessary to multiple rotary cutting apparatus for each expectation driving shaft diameter.

Thus, exist and another drive shaft with identical size or another size is replaced by wherein drive shaft The need for the rotary cutting apparatus of gear assembly with matching.
