本発明は、術中又は術後等における術部の切除されるべ
き組織片を吸引して切除するために専用されるロータリ
ースクレイパーに関ｆる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary scraper dedicated to suctioning and resecting tissue pieces to be excised at a surgical site during or after surgery.
術部に残存する切除される−べき組織片等を取除くため
に種々の方法が行われているが、従来装置にあってはそ
の殆んどが切除の際、同時に細い血管等を傷つけてしま
うためその使用が制限されることが多く、切除の効果を
十分に達成することができなかった。Various methods have been used to remove tissue fragments that remain at the surgical site and should be resected, but most of these methods do not damage small blood vessels or the like during resection with conventional devices. Its use is often limited because it is stored away, and the full effect of resection cannot be achieved.
本発明は、かかる実状に鑑みてなされたもので、術中又

レイパーを提供することをその目的とするものである。The present invention has been made in view of the above circumstances, and is designed to fully remove tissue fragments to be removed during or after surgery.
Moreover, the object is to provide a rotary scraper that does not cause damage to small blood vessels.
本・発明に係るロータリースクレイパ”−０ｔＷな ・
特徴は、実質的に除去されるべき組織片のみを吸引して
これを回転刃でカットするもので、反面血管等の弾力性

ば切除を免れる如くしうる点に存するものである。The rotary scraper according to the present invention is 0tW.
The feature is that only the tissue pieces to be removed are suctioned and cut with a rotating blade.On the other hand, elastic items such as blood vessels can be removed by adjusting the suction pressure etc. so that they are not suctioned. It lies in the fact that it can be avoided.
以下図面を参照し実施例に基づいて本発明を説明する。The present invention will be described below based on embodiments with reference to the drawings.

に伴い核外筒内で回転するようになっている。FIG. 1 is an overall perspective view showing a rotary clay/IP- according to the present invention. An outer cylinder 2 shown in Fig. 2 (N) protrudes from the tip of the souffler main body 1, and an inner cylinder 3 shown in Fig. 2 (B) protrudes from the nuclear outer cylinder. As shown, the rear part of the inner cylinder is fitted and closely supported by a bearing 4 and fixed to a rotating shaft 6 connected to a motor 5, so that it rotates within the core outer cylinder as the shaft rotates.

いる。Suction ports 2a for suctioning tissue pieces to be removed are arranged in parallel at appropriate intervals on the front end and peripheral wall of the outer cylinder 2. The outer diameter of the outer cylinder 2 is approximately 6 to 7 m.
また、これに嵌入される内筒３には、吸引口２ａの周縁

す。The cut tissue pieces 8 are collected together with contaminated physiological saline, aspirated blood, body fluids, etc. through a small window 9 at the rear of the inner cylinder 2 shown in FIG. It is designed to be discharged through 11. Further, reference numeral 12 denotes a lead wire bundle in which IJ-do wires are assembled, which connect a lever 14 for supplying electric power to the device 5 and for communicating a suction means (not shown) with a lever 14 for adjusting suction pressure (described later). show.

ないように配慮されねばならないことから弾力性のない
組織片を内筒内に吸引する程度に吸引圧を随時調節しり
・るものであることが必要である。The main difference between the device of the present invention and conventional resection devices is that the device sucks the tip of the tissue piece to be resected almost inward from the inner wall of the inner tube, and rotates slidingly against the outer tube. This consists in cutting at the peripheral edge of the suction port using the blade of the inner cylinder. Therefore, the device of the present invention is characterized by the presence of a suction means. Since the suction force must be controlled so as not to cut small blood vessels, etc., it is necessary to adjust the suction pressure at any time to the extent that non-elastic tissue pieces are suctioned into the inner cylinder.

A roughening is provided at the tip of the main body 1. The main body 1 also includes a switch 13 for rotating or stopping the motor 5, and a suction pressure adjustment lever 14.

めて有用なロータリースフレイノや−である。The present invention is based on the above configuration, and has the effect of cutting the tissue fragment to be resected whose tip is sucked into the inner cylinder by the sliding rotation of the inner and outer cylinders and discharging it out of the system. In particular, rotary suction cutting is extremely useful for removing unnecessary tissue, substances, etc. during and after surgery, since blood vessels with elasticity that cannot be suctioned are not subject to resection due to suction cutting.
