Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Fig. 1 is the utility model discloses a maxillary sinus mucous membrane protector structure sketch map, fig. 2 is the utility model maxillary sinus mucous membrane protector's main view. As shown in fig. 1 and 2, the utility model provides a maxillary sinus mucosa protector, which comprises a bracket 10 and a protective umbrella 20.

As shown in fig. 1 and 2, the support 10 includes a first jaw 11 and a second jaw 12 rotatably connected to each other. The first forceps body 11 and the second forceps body 12 both include a forceps head and a forceps handle, and the forceps head can be opened or closed by the forceps handle.

Specifically, the first caliper body 11 and the second caliper body 12 can be rotatably connected through a pin, a rotating shaft or a fixed shaft. In the present embodiment, the first caliper body 11 and the second caliper body 12 are rotatably connected to the bracket 10 in an "X" shape by a rotation shaft.

In specific implementation, the first forceps body 11 and the second forceps body 12 can be made of smooth metal or other materials capable of resisting high temperature and high pressure, so as to perform high-temperature sterilization on the maxillary sinus mucosa protector.

As shown in fig. 1 and 2, the jaw of the first jaw 11 and the jaw of the second jaw 12 form a first bending portion 111 and a second bending portion 121, respectively. That is, a first bent portion 111 is formed at one end of the first caliper body 11, and a second bent portion 121 is formed at a region of the second caliper body 12 corresponding to the first bent portion 111.

The first bending part 111 and the second bending part 121 are arranged, so that the maxillary sinus mucosa 40 can be lifted and positioned, and the maxillary sinus mucosa 40 is prevented from continuously moving along with the breathing of a patient in the operation process; at the same time, the inclination angle of the stent 10 relative to the bone window 30 can be increased to prevent the influence on the intraoperative visual field.

Specifically, the first bending part 111 and the second bending part 121 are bent toward the same side of the bracket 10. That is, the first bent portion 111 and the second bent portion 121 are formed by bending the first caliper body 11 and the second caliper body 12 to the same side of the bracket 10 at a predetermined angle, respectively.

In specific implementation, the bending angles of the first bending portion 111 and the second bending portion 121 are the same, so as to ensure that the first bending portion 111 and the second bending portion 121 can approximately coincide with each other along with the furling of the first forceps body 11 and the second forceps body 12, so that the stent 10 can extend into a bone window without damaging the mucosa 40 of the maxillary sinus.

With continued reference to fig. 1 and 2, a first protrusion 113 and a second protrusion 123 are respectively disposed at the ends of the first bending portion 111 and the second bending portion 121. The first protrusion 113 and the second protrusion 123 are smooth and blunt. By providing the first protrusion 113 and the second protrusion 123 which are smooth, the maxillary sinus mucosa protector can be prevented from damaging the maxillary sinus mucosa in the entrance and exit of the bone window or during the operation.

In specific implementations, the first protrusion 113 and the second protrusion 123 may be cylindrical or approximately cylindrical or hemispherical or spherical or elliptical.

As shown in fig. 1 and 2, a first hand hole 112 and a second hand hole 122 are formed in the handles of the first forceps body 11 and the second forceps body 12, respectively. Specifically, a first hand hole 112 and a second hand hole 122 are respectively formed at one end of the first forceps body 11 and the second forceps body 12 away from the first bending portion 111 or the second bending portion 121.

Through setting up first hand hole 112 and second hand hole 122, be convenient for medical personnel one-hand to hold or operate maxillary sinus mucosa protector. For example, the first and

second forceps bodies

11 and 12 can be relatively rotated through the first and

second hand holes

112 and 122 to open or close the first and

second forceps bodies

11 and 12.

In one embodiment, the first hand hole 112 and the second hand hole 122 may be circular or semicircular. In the present embodiment, the first hand hole 112 and the second hand hole 122 are both semicircular, and the semicircular hand holes can be formed by bending the side of the handle of the first forceps body 11 and the side of the handle of the second forceps body 12 facing away from each other.

As shown in fig. 1 and 2, the protective umbrella 20 is connected to the first bending portion 111 and the second bending portion 121, and can be unfolded or folded by the first bending portion 111 and the second bending portion 121. That is, the protective umbrella 20 is connected to the first bending portion 111 and the second bending portion 121 through two different sides thereof, and can be brought into an unfolded state or a folded state by the relative rotation of the first pincer body 11 and the second pincer body 12.

By folding the protective umbrella 20, the volume of the maxillary sinus mucosa protector can be reduced, so that the maxillary sinus mucosa protector can be inserted into the bone window 30; by unfolding the protective umbrella 20, the maxillary sinus mucosa 40 between the forceps heads of the first forceps body 11 and the second forceps body 12 can be limited above the protective umbrella 20, and the mucosa can be prevented from being damaged when the aggregate is implanted below the protective umbrella 20.

Specifically, the umbrella 20 is fan-shaped. The protective umbrella 20 is made of a material which is soft and can be folded at will, but can not be stretched or is not easy to deform. In specific implementation, the protective umbrella 20 can be made of medical silica gel material or memory metal material. Can also satisfy the disinfection demand of parachute-20 through adopting medical silica gel material or memory metal material, be favorable to realizing maxillary sinus mucous membrane protector recycles, can reduce medical resource's waste.

In specific implementation, the protective umbrella 20 is sleeved on the first pincer body 11 and the second pincer body 12, and is prevented from falling off by the limit of the first protrusion 113 and the second protrusion 123.

Fig. 3 is the utility model discloses a maxillary sinus mucous membrane protector user state schematic diagram one, fig. 4 is the utility model discloses a maxillary sinus mucous membrane protector user state schematic diagram two. The use of the maxillary sinus mucosa protector will be described in detail below with reference to fig. 3 and 4.

As shown in fig. 3 and 4, in the case of performing the maxillary sinus lift surgery, when the maxillary sinus mucosa 40 is separated from the bone wall and the bone graft material is prepared for implantation, the mucosa protector is grasped through the first hand hole 112 and the second hand hole 122; then, closing the mucosal protector and extending the mucosal protector from the bone window 30 into the cavity between the maxillary sinus mucosa 40 and the bone wall, and pressing the first protrusion 113 and the second protrusion 123 against the contralateral bone wall; then, the mucous membrane protector is opened, so that the maxillary sinus mucous membrane 40 is limited above the umbrella 20, and the bone grafting area is below the umbrella 20; and finally, implanting bone grafting materials into the bone grafting area, and carefully taking out the mucous membrane protector after the completion of the bone grafting materials, thereby completing the operation of the bone grafting operation.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
