Description
Technical Field
The utility model relates to the field of medical appliances, in particular to a rotary cutter for a tumor.
Background
According to incomplete statistics, in the current treatment of uterine diseases, mainly abdominal hysterectomy is adopted as the main part of tumor excision, and the proportion of vaginal hysterectomy is relatively small, so that the concept of minimally invasive surgery is introduced into the gynecological medical field along with the maturation of laparoscopic technology, and the vaginal hysterectomy conforming to the minimally invasive principle is paid attention to domestic and foreign gynecologists again. In laparoscopic hysterectomy or hysteromyoma excision, the resected uterus or myoma cannot be directly taken out from the abdominal cavity through a puncture sheath or a surgical instrument channel due to the large volume, and generally the uterus or myoma is crushed into strips by other devices and then taken out of the body through a pipeline, so that the incision is prevented from being enlarged.
The electric hysterectomy device is a device which is more commonly used for smashing and resecting uterus or myoma, the rotating wheel of the existing electric hysterectomy device can only use rotary cutter tubes with phi 16.0mm, phi 18mm and phi 20mm, the caliber of the rotary cutter tube is relatively small, the smashing efficiency on teratoma, uterus, polyp and the like is low, the risk of scattering in the rotary cutting process exists, and the rotary cutter tube is entirely made of medical stainless steel materials. The medical stainless steel can keep good corrosion resistance in human bodies, so that the rotary cutter tube made of the medical stainless steel is often reused after sterilization and cleaning, but operators cannot control the reuse times and the quality of the stainless steel on the market artificially, and the problems of cross infection or biocompatibility of patients are avoided.
Disclosure of Invention
The utility model aims to provide a rotary cutter for a tumor, which has affinity with human tissues and can improve the efficiency of crushing the tumor.
The utility model is realized by the following technical scheme: the main body of the rotary cutter is a rotary cutter tube, and the rotary cutter tube comprises a rotary cutter head and a tube body, wherein a serrated rotary cutter edge is arranged at the head end ring of the rotary cutter head, and the rotary cutter head is connected with the tube body in a detachable manner; the rotary cutting tool bit is made of biological ceramic materials.
Compared with the prior art, the utility model has the beneficial effects that:
1. the rotary cutting tool bit is made of a biological ceramic material, and the biological ceramic material has high bending strength, good wear resistance, good biocompatibility with human tissues and can be sterilized and reused.
2. The rotary cutter tube with the diameter phi of 30mm is additionally arranged, so that the requirement of rapid crushing of tumors such as teratomas, uterus and polyps is met, and the influence of crushed tissues on other tissues in the process of rotary cutting the tumors is reduced.
3. The utility model can improve the working timeliness of medical staff and release more invalid working time by improving the crushing efficiency.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a schematic structural view of a threaded connection of a rotary cutter head and a pipe body.
Description of the reference numerals: 1 rotary cutter head, 2 pipe body, 3 sawtooth form rotary cutting edges, 4 screw threads.
Detailed Description
The present utility model will be described in detail with reference to the accompanying drawings, but the protection of the present utility model is not limited to the following:
referring to fig. 1 and 2, a rotary cutter for a tumor is a rotary cutter tube, and comprises a rotary cutter head 1 and a tube body 2, wherein a serrated rotary cutter edge 3 is arranged at the head end ring of the rotary cutter head 1, and the rotary cutter head 1 is connected with the tube body 2 in a detachable manner;
the rotary cutting tool bit 1 is made of biological ceramic materials. The serrated rotary cutting edge 3 can improve the crushing effect on the tumor, improve the operation efficiency, accelerate the operation process and reduce the influence of crushed tissues on other tissues in the process of rotary cutting the tumor.
The pipe diameter of the rotary cutter pipe is phi 16mm, phi 18mm, phi 20mm or phi 30mm. According to different requirements, the pipe diameter can be designed into other pipe diameters.
The pipe diameter of the rotary cutter pipe is preferably phi 30mm. The rotary cutter tube designed with phi of 30mm has higher crushing efficiency on teratomas, uterus, polyps and the like.
The biological ceramic material is alumina biological ceramic, zirconia ceramic or carbon biological material. The structure of the biological ceramic material is stable, and the biological ceramic material belongs to an inert material, and the biocompatibility of the inert material contacted with a human body is good; the bonding force in the molecule is stronger, the strength, the wear resistance and the chemical stability are higher, the chemical property is stable, the biocompatibility is good, and the material is more suitable for being used as a manufacturing material of a rotary cutter than medical stainless steel materials.
The pipe body 2 is made of plastic materials. The tube body 2 made of plastic material is used as a disposable replaceable tool, so that the cross infection of patients can be reduced, and the cost can be saved.
The rotary cutter head 1 and the pipe body 2 are connected through threads 4. The screw thread 4 is opposite to the rotating direction of the rotating screw thread of the equipment, so that the rotary cutter head 1 can not fall off due to torsion or other factors when the rotary cutter tube rotates to cut the tumor, and safer operation is ensured.
While the utility model has been illustrated and described with respect to specific embodiments and alternatives thereof, it will be appreciated that various changes and modifications can be made therein without departing from the spirit of the utility model. It is, therefore, to be understood that the utility model is not to be in any way limited except by the appended claims and their equivalents.
