Embodiment 1

[0036] Detachable suction curette set for endoscopic skull base surgery, e.g. figure 1 and figure 2 As shown, it includes a curette. The curette includes a detachably connected handle 1 and a scraper head 4. Both the handle 1 and the scraper head 4 are hollow inside, and the two are connected by threads or buckles. The other end of the scraper head can be connected with the suction tube 6. To ensure the sealing, the handle 1 and the suction tube 6 are connected by threads, or a rubber ring is set in the handle 1 to connect with the suction tube 6. The suction tube is a steel pipe , and then connected to the hose, or the suction tube 6 can be a hose, the hose is connected to a negative pressure suction device, the scraping head 4 is in the shape of a straight tube or the middle part can be bent to a set angle, and one end of the scraping head 4 is set for scraping In addition to the scraping of the tissue in the operation area, the handle 1 is provided with a vent hole 3 comm...

Embodiment 2

[0046] The difference between this embodiment and embodiment 1 is:

[0047] The scraping head is a whole structure.

Embodiment 3

[0049] The difference between this embodiment and embodiment 1 is:

[0050] The handle and the scraping head are not detachable connecting bodies, but are set in an integrated structure with a hollow interior.

Abstract

The invention discloses a special detachable suction type curet set for endoscopic skull base surgery and a method. The special detachable suction type curet set comprises a curet, wherein the curet comprises a handle and a curet head; the handle is detachably connected with the curet head; the interiors of the handle and the curet head are respectively of a hollow structure to form a continuous suction channel; the end part of the handle is connected with a suction device; the curet head is in a straight tube shape, or the middle part of the curret head is bent into a setting angle; one end of the curet head is provided with a curet opening for scraping tissues in a surgery part; an air ventilating hole is formed in the handle and is communicated with the suction channel. The special detachable suction type curet set has the advantages that by adopting a structural design, according to the clinical actual requirements, and the special requirements of endoscopic skull base surgery on special apparatuses, a surgery apparatus contains one curet set, so that the requirements of various types of skull base surgery are met; the structural design is reasonable, the flexibility in use is realized, the combination is convenient, the clear surgery view field is favorably maintained, the surgery time is shortened, the safety in surgery is improved, the cleaning and disinfection are easy, and the reliability and durability are realized.

Description

technical field [0001] The invention relates to endoscopic skull base surgery, in particular to a special detachable suction curette set and method for endoscopic skull base surgery. Background technique [0002] At present, endoscopic nasal cavity and sinus surgery has been widely carried out in China for about 20 years, and has become the mainstream surgical method. Conventional endoscopic sinus surgery is mature and complete in terms of technology and surgical instruments. With the development of medical technology, in the past 10 years, more complex and difficult endoscopic skull base surgery has been gradually carried out in some high-level tertiary hospitals in China, such as endoscopic transnasal or peroral skull base lesion resection. Endoscopic transnasal saddle tumor resection, nasal sinus malignant tumor involving skull base resection, endoscopic transnasal infratemporal fossa pterygopalatine fossa tumor resection, endoscopic transoral jugular foramen lesion resec...
