Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a magnetically controlled head and neck cavity building hook. Background Art

[0002] The scale of the minimally invasive surgical instruments and accessories market in my country has grown rapidly in the past five years, but there are few reports on instruments suitable for head and neck surgery with complete endoscopic surgery. At present, the mainstream procedures for complete endoscopic parotidectomy, submandibular gland resection, and neck lymph node dissection use an incision behind the ear hairline. This surgical approach has no natural cavity and requires artificial cavity creation. At the same time, a retractor is required to maintain the cavity space after cavity creation. Traditional surgical retractors will occupy a certain volume, making the already narrow cavity even narrower, greatly limiting the scope of surgical operation. Therefore, designing a reasonable head and neck cavity retractor that does not occupy the surgical channel can effectively promote the development of head and neck endoscopic surgery. Utility Model Content

[0003] In view of the above problems, the utility model provides a magnetically controlled head and neck cavity construction hook, which consists of two parts: a magnetic film and a magnetically controlled handle. It adopts an external magnetically controlled traction method and has no connecting structure. During the cavity construction process, no instruments occupy the surgical channel, which is more conducive to exposing the surgical field and improving surgical efficiency.

[0004] The technical solution of the utility model is as follows:

[0005] A magnetically controlled head and neck cavity building hook, comprising:

[0006] A magnetic film, one side of which is an adhesive layer and the other side is provided with one of an N-pole magnetic end or an S-pole magnetic end;

[0007] The magnetic control handle is provided with the other of an N-pole magnetic end and an S-pole magnetic end, which is attracted and matched with the magnetic film.

[0008] In a further technical solution, the magnetic film includes a base layer, the adhesive layers respectively arranged on two sides of the base layer, and a first magnetic suction piece, and the first magnetic suction piece is an N-pole magnetic end or an S-pole magnetic end.

[0009] In a further technical solution, the base layer is made of medical gauze with good air permeability.

[0010] In a further technical solution, an adhesive protective film is provided on the outer side of the adhesive layer.

[0011] In a further technical solution, the magnetic control handle includes a pull rod, one end of which is provided with a pull hook, the other end of which is provided with a suction plate, the suction plate is provided with a second magnetic suction piece, and the second magnetic suction piece is an N-pole magnetic end or an S-pole magnetic end.

[0012] The working principle of the above technical solution is as follows:

[0013] When using the magnetically controlled head and neck cavity construction hook of the utility model to construct a cavity in the head and neck, firstly tear off the sticky protective film on the outside of the magnetic film to expose the adhesive layer, and stick it on the skin on the surface of the patient's surgical area. Then, the magnetically controlled handle and the magnetic film are attracted together to lift a certain area of ​​skin and maintain the cavity construction space.

[0014] The beneficial effects of the utility model are:

[0015] 1. The utility model has a simple structure, low processing cost, convenient operation and easy promotion;

[0016] 2. The utility model adopts an external magnetically controlled traction method, has no connection structure, and no instruments occupy the surgical channel during the cavity creation process, which is more conducive to exposing the surgical field and improving surgical efficiency.
