Description
Technical field
The present invention relates to technical field of medical instruments, specifically, be the intelligent apparatus of a kind of high-resolution measurement tissue thickness.
Background technology
Using anastomat to carry out reconstruction of digestive tract is to substitute a kind of mechanical system that traditional-handwork is sewed up.This type of apparatus includes the end effector of the jaw member of a pair energy collaborative work, if to be used in endoscope or laparoscopic surgery by described apparatus, the most described jaw member needs to pass sleeve channel.One of jaw member is a groove, and described groove can accommodate nail bin, and another jaw member is nail anvil.When tissue is squeezed by needs, rotated by handle and make the axial distal end of anastomat promote nail anvil, so that nail anvil is downward, reach the purpose of squeezing tissue.
The use of anastomat needs to follow certain specification, can reach target.Wherein, it is important that be exactly some the selection of identical nail bin, the identical nail bin of different colours the is built-in anastomosis staple of differing heights, height resolution reaches 0.1mm, it is adaptable to the tissue of different-thickness.Anastomat production firm, in the operation instruction of anastomat, only tells user, will select suitable anastomosis staple according to tissue thickness.Here the problem existed has: first, and it is unlikely completing of a task that doctor with the naked eye differentiates the difference of the 0.1mm order of magnitude under surgical environments；Secondly, i.e. enable a physician to differentiate this difference, but owing to tissue has certain elasticity, how to define its thickness when operation？For this reason, it may be necessary to a kind of medical device, it is possible to provide objective tissue thickness data for doctor, to assist doctor to select correct anastomosis staple, smoothly complete anastomosis operation.
Furthermore, doctor, when using anastomat, needs according to perusal, subjective judgment tissue thickness, selects the corresponding nail bin that coincide；This process lacks objective basis, easily causes the selection of identical nail bin improper: when nail bin selects higher, easily cause Anastomotic bleeding；When nail bin selects the shortest, easily cause surrounding tissue and squished, affect anastomotic healing, cause fistula of operative incision.
Chinese patent literature CN201410510194.X, at on 09 29th, 2014 applying date, patent name is anastomat auxiliary device, there is anastomat and the operating theater instruments of this auxiliary device, disclose a kind of anastomat auxiliary device, including auxiliary device body, it is arranged on described auxiliary device body interior and the adapter being connected with its near-end with anastomat body, the pushing means being connected with described adapter far-end, it is connected with described pushing means far-end and closeable moving jaw and regular jaw, it is arranged on the pressure-bearing device between described moving jaw and described regular jaw, and described pressure-bearing device is made up of one or more pressure-bearing unit.Anastomosis staple nail required for judging before coincideing is high, thus select correct identical nail bin, the embodiment of this device is, in pressure-bearing critical value range set in advance, tissue is carried out precommpression, make tissue thickness be evenly distributed, be easy to sew up, judged by the size in Guan Bi gap simultaneously required for anastomosis staple nail height, the selection result of the nail bin that coincide by the instruction of pushing means；Pressure-bearing device contains pressure-bearing spring, can play cushioning effect, prevents tissue from excessively being squeezed；When the pressure that tissue bears exceedes marginal value, locking device can be triggered, make operator cannot continue to fire, thus protective tissue.Its embodiment is to measure during organizing and implementing prepressing, selects, according to measurement result, the nail bin that coincide, re-uses anastomat and coincide at same position；But do not indicate the concrete numerical value to the pressure size that tissue is applied, knowable to it describes, prepressing process can make tissue thickness's distribution more uniform, this process excretes along with extracellular fluid, thus it is envisioned that, pressure values will not be the least, and tissue has gone through the effect being similar to anastomat squeezing in this process, if the time of measurement is long, it is possible to also can cause ischemia；After being measured, when doctor re-use anastomat carry out coincide time, needs are on all four position when finding and measure, flexibility characteristics and the complex environment of inside of human body due to identical object, this target is extremely difficult to, if and can not be completely the same, it is meant that the tissue location beyond anastomotic stoma has had been subjected to extra damage, and this is totally unfavorable for the post-operative recovery of patient.This starting point is that the tissue thickness of measurement is the most accurately after the squeezing suitable to organizing and implementing and anastomat, but tissue thickness's measurement is to have a pressure range optimized, when to the pressure organized and implemented within this scope, the tissue that can make softness is fixed, will not be produced histoclastic constructive variations simultaneously, the standard that this pressure range is approved by industrial quarters.Therefore, the measurement to tissue thickness should follow this standard, without the squeezing effect pursued and anastomat is suitable.
