The background of the present invention

Technical field

This disclosure relates to for removing tissue from body passage, such as removing 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

Develop in multiple technologies and instrument of the artery with removal or repair tissue in similar body passage.This Technology and the usual purpose of instrument are to remove the atherosclerotic plaque in patient's artery.Artery sclerosis passes through patient vessel's The accumulation of fat deposition (atheroma) in theca interna (that is, in subendothelial face) is characterized.Often over time, it is initial heavy Long-pending is relatively soft, atherosclerotic plaque of the atheromatous material hardening rich in cholesterol into calcification.This The flowing of atheroma limit blood, and be commonly referred to as thus Stenotic pathologic change or restenosis, thus stop material Material is referred to as stenotic material.If reservation is untreated, 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.In a kind of types of devices In, such as in United States Patent (USP) No.4, shown in 990,134 (Ao Si), covered with abrasiveness cutting material, such as boart boart The rotation flash of grain (diamond particles or dust) is carried on the far-end of flexible rotatable drive shaft.

United States Patent (USP) No.5,314,438 (Xie Teman) show another rotary cutting apparatus with rotatable drive shaft, drive A part for moving axis has enlarged diameter, and at least a portion of this enlarged diameter portion is covered with grinding-material to limit drive shaft Abrasiveness part.When rotated at high speed, means of abrasion can remove stenotic tissue from artery.

United States Patent (USP) No.5,314,407 (Ao Si) is shown can be with showing in this 134 and Xie Teman of Austria 438 patents The details for the handle types that the rotary cutting apparatus of the type gone out is used in combination.The handle types shown in Ao Si 407 patents are Through being commercialized by heart technology (HeartTechnology) limited company (Redmond, Washington), now by boss Scientific company (Na Dike, Massachusetts) of pausing is all and in trade mark turnery intervention therapeutic instrumentsLower sale In rotary cutting apparatus.The handle of device include multiple parts, including compressed gas-driven turbine, for clamping Extend through drive shaft, the mechanism of the seal wire of a part for optic fiber tachometer and for salt solution pumping to be passed through into drive shaft Pump.

Drive shaft (flash related with its is together) withThe connection between turbine in device is forever Long；However, normally needing to use the flash of more than one size in patch inadvertent closure.That is, generally make first With the flash of reduced size so that narrow be opened to certain diameter, and then the flash of more than one large-size be used for into One step is opened narrow.The use of multiple flashes of subsequent larger diameter sometimes referred to as " stepping (step up) technology " and byThe manufacturer of device is recommended.In a variety of flash technologies, it is necessary to which the flash for this each continuous size is used It is newDevice.The need for being directed to patch excision system accordingly, there exist one kind, patch excision system will allow This handle using only a handle and is attached to appropriate drive shaft and organizes to remove work by surgeon through whole operation Tool (for example, flash) is to start operation and then drive shaft and Tissue removal tools be replaced by with different sizes or very To the drive shaft of the Tissue removal tools of different designs.

Subsequent version have been incorporated into and change the flexible distal portion of drive shaft to have together with flash There is the ability of another distal portions of the drive shaft of different size flashes.The ins and outs of this system are included in Wulfman's Entitled " drive axle systems can be connected " and in the United States Patent (USP) No.5,766,190 that on June 16th, 1998 announces.This is System utilizes flexible drive shaft, and what this flexible drive shaft had connection/broken features to allow that surgeon makes flexible drive shaft can The flexible proximal end part that distal portions are changed together with flash and the drive shaft for the turbine for being connected to handle disconnects, and thus allows hair Side size is changed in the case where not abandoning whole patch excision units.Each replaceable drive shaft section is all disposed within it In itself replaceable guide casing and catheter body.The flexible proximal end part of drive shaft is permanently attached to turbine in such a system And it is changed without.This system is by Boston technology Corp in Luo Talinke systems (Rotalink) business It is commercialized under entitling.Although RotalinkAllow someone to change flash size, but actually need to make driving The exchangeable portion disjunction of axle open and with another replaceable partial replacement of drive shaft it the step of it is extremely complex and require Operate very small part opposite fine.

First, catheter body must disconnect with handle and include disconnecting with exposure coupling to distal end is mobile away from handle The proximal part of the flexible drive shaft of part and a part for distal portions.By making locking pipe be slided to distal end, it is allowed in flexibility Complementary locking teeth on the proximal part and distal portions of drive shaft is disengaged from and disconnects this connector.Then there is difference The similar flexible distal drive shaft section of flash may be coupled to the flexible proximal end part of drive shaft.To complete this assembling, driving The locking teeth that the distal end of moving axis replaces on the near-end of part first must be with the far-end of the proximal part in drive shaft complementation Locking teeth is aligned longitudinally and rotatably.Because soft drive shaft diameter is typically less than 1mm, therefore the size of locking teeth is similar Ground is very small, so as to need significant manual dexterity with visual acuity to be appropriately aligned and interlock locking teeth.Once locking teeth Suitably mutually locking each other, then locking pipe proximally slides to fix this coupling (also with very small diameter).Then Catheter body is necessarily connected to handle housing.

Although this system allows someone that a kind of size flash (together with a part for drive shaft) is replaced by into another size Flash, but it is not simple to perform the operation and quite must carefully perform that this, which changes operation,.Perform the personal necessary of operation So do at the same the element for dressing surgical gloves to protect the personal blood away from patient and keep system it is sterile.Outside Section's surgical glove reduces the personal tactile for performing replacing operation and so that this replacing operation is more difficult.

In recent years, make efforts to exploitation and remove use with its tissue with easily attachment and/or replacing drive shaft The rotary cutting apparatus of tool.

For example, the United States Patent (USP) Nos.6 that all entirety is incorporated herein by reference, 024,749 (Xie Teman etc.), 6, 077,282 (Xie Teman etc.), 6,129,734 (Xie Teman etc.) and 6,852,118 (Xie Teman etc.) disclose a kind of rotary-cut dress Put, this rotary cutting apparatus has the replaceable shaft sleeve of the housing for the handle housing for including removedly could attach to device.
