Description
Technical field
The present invention relates to a kind of operating theater instruments, more particularly to a curing hysteromyoma or corpus uteri rotary-cut grinder, belong to doctor
Treat apparatus.
Background technology
It is well known that under laparoscope subtotal hysterectomy or hysteromyomectomy because with micro- mouth it is small, recover fast etc. excellent
Point has clinically been promoted the use for many years；At present, fibroid is generally rejected using fibroid grinder or is removed secondary complete
Uterus.The fibroid grinder is generally by the rotary-cut crushing knife structure cylindrical in funnelform sheath, in the sheath
Into.Myomata rotary-cut can subtract body and take out external by rotary-cut crushing knife under the driving of motor, it is to avoid what Tradtional laparotomy was brought
Long operative incision.But in surgical procedure, myomata is carried out in unprotect situation（I.e. peeling knife is completely sudden and violent in myomata sample
It is exposed under the situation in abdominal cavity and carries out）, myomata cell, cell mass or tissue crisp chip come off and can pollute abdominal cavity, and plant in abdominal cavity.
Therefore, food and medicine Surveillance Authority of the U.S.（FDA）Warning is sent on April 17th, 2014：Laparoscopic is cut
Remove and when fibroid is divested, there is the possibility that the malignant tissue for causing concealment sends out using myomata grinder；Lacked due to preoperative
Weary effective method for differentiating fibroid and benign from malignant tumors, taken precautions against without protection abdominal tissue pollution effective means it
Before, it is not recommended that it is continuing with myomata grinder.At present, most of hospitals of the U.S. have stopped using myomata grinder.This warning
It is restricted the laparoscopic surgery application of comparative maturity, whether domestic annual numerous patients with uterine myoma selects myomata
To also huge puzzlement be faced with by crushing operation.
For above-mentioned warning, Chinese patent literature discloses Application No. " 201420793705.9 ", entitled " controllable aerating
Gas-closed myomata sample crushes bag " utility model patent, first the myomata cut off can be placed in one using crushing bag,
Then recycle traditional fibroid grinder to carry out rotary-cut to myomata and subtract body taking-up in vitro.The isolation that bag is crushed due to having is protected
Protect and collect pulverized sample, therefore can avoid that abdominal tissue is polluted and malignant tissue sends out；So as to make myomata
Operation is crushed to be carried out.
But when being performed the operation using the fibroid grinder of traditional structure, because knife length of tube is long more than sheath
Degree, the cutting edge of knife pipe can stretch out at the lower port of sheath；Careless slightly cutting edge is operated to scratch crushing bag and cause myomata
Cell, cell mass or tissue crisp chip leakage are become scattered about in abdominal cavity, so as to pollute；Have that operation difficulty is big, pollution risk is high
Etc. defect.In addition, being not provided with inflation inlet and exhaust outlet on the sheath of the fibroid grinder of traditional structure, it is necessary to first will rotation
Cutting could be inflated after crushing knife takes out from sheath by sheath upper port into crushing bag；Not only troublesome poeration, and
Crushed in myomata crushing process without normal direction and tonifying Qi or exhaust are carried out in bag.
The content of the invention
In view of the foregoing defects the prior art has, the present invention is intended to provide one kind can avoid crushing bag breakage, operation letter
Single convenient fibroid or corpus uteri rotary-cut grinder.
To achieve these goals, the present invention uses following technical scheme：It is by being adapted cylindrical structure with sheath
Rotary-cut crushing knife constitute；The sheath include in funnelform sheath, be threadedly secured to the sheath upper port swivel nut,
The upper sealing cap for being fixed on the swivel nut top, the lower blast cap for being fixed on the swivel nut bottom, the rotary-cut crushing knife include the front end mouth of pipe
Knife pipe with wavy cutting edge, the knife base for being fixed on structure in the form of annular discs on the knife pipe；At least one is fixed with sheath
Valve, the lower port of the sheath is oblique groove or aduncate curved surface groove；The front end mouth of pipe of knife pipe is located at lower port most
Between lower and highest point.
Lower blast cap is in concave shape structure, and the otch in cross or M shape structure is arranged at the bottom of the lower blast cap；In swivel nut
There is sealing ring between sheath.
Compared with the prior art, the present invention is by adopting the above-described technical solution, the lower port of sheath has been changed to tiltedly to cut open
Mouth or aduncate curved surface groove shape structure and the length for shortening knife pipe, therefore, it is possible to ensure that the front end mouth of pipe of knife pipe begins
The position between the lowest part of sheath lower port and highest point is in eventually；The sheath wall of sheath lower port lowest part can be blocked, isolated
The front end mouth of pipe of knife pipe contacts with crushing bag and causes its damaged, so as to reduce operational control fibroid rotary-cut grinder
Difficulty, improves operation safety.Further, since adding two valves on sheath（One be used for crush bag in inflation,
Another is used to be vented）, therefore it is that can be achieved to inflation in crushing bag or be vented that need not take out knife pipe from sheath crowd.The present invention
Simple in construction, easy to operate, security reliability is high, is cut entirely available for fibroid, uterus time is taken out in laparoscope Minimally Invasive Surgery
Except the corpus of operation takes out and Abdominal mass taking-up.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of blast cap under the present invention；
Fig. 3 is Fig. 2 upward view.
In figure：Upper sealing cap 1, swivel nut 2, lower blast cap 3, sheath 4, lower port 5, myomata 6, crushing bag 7, knife pipe 8, valve 9, knife
Base 10, otch 11.
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings：
As shown in Figures 1 to 3：The rotary-cut crushing knife structure that the present invention is adapted by sheath, cylindrical structure and with the sheath
Into.The sheath by funnelform sheath 4, be threadedly secured to the swivel nut 2 of the sheath upper port, be fixed on the swivel nut top
The upper sealing cap 1 at end, two valves 9 for being fixed on the lower blast cap 3 of the swivel nut bottom, being fixed on sheath 4 are constituted, under sheath 4
Port 5 is oblique groove or aduncate curved surface groove shape structure；The rotary-cut crushing knife includes the front end mouth of pipe with wavy
Cutting edge（Do not indicated in figure）Knife pipe 8, be fixed on knife base 10 in the form of annular discs on the knife pipe.When knife pipe 8 from top to bottom according to
It is secondary through upper sealing cap 1, swivel nut 2, lower blast cap 3 and when inserting in sheath 4, the front end mouth of pipe of knife pipe 8 is located exactly at lower port 5 most
Position between lower and highest point.
Gas uses concave shape from leakage in bag 7, lower blast cap 3 is crushed when being extracted in order to avoid rotary-cut crushing knife from sheath
Structure, the bottom of the lower blast cap has in cross or the otch of M shape structure 11.When rotary-cut crushing knife is extracted from sheath,
Four of the lower bottom of blast cap 3 or eight valves will automatically be closed because of the state of affranchising.
In order to avoid gap location leakage of the gas between sheath 4 and swivel nut 2, provided with sealing between swivel nut 2 and sheath 4
Circle.
Operation principle：Sheath is inserted in the crushing bag 7 equipped with myomata 6, then sequentially passed through knife pipe 8 from top to bottom
Sealing cap 1, swivel nut 2, lower blast cap 3 and insert in sheath 4, start motor（Not shown in figure）Can be by the front end mouth of pipe of knife pipe 8
Rotary-cut is carried out to myomata 6, is crushed.
