Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially ear cartilage fascia former. BACKGROUND

[0002] At present, part of middle ear, inner ear operation needs to take the self cartilage (such as: ear screen cartilage) or temporal muscle fascia to carry out the repair to ear damaged part. For example: tympanoplasty needs to use self ear screen cartilage to repair it. In operation, the conventional cartilage cutting method is to cut and take out the cartilage after separating and exposing the cartilage, and the cartilage taken out at this time is often irregular, and does not conform to the actual size of the damaged part. Therefore, the cartilage taken out needs to be cut again according to the size of the actual damaged part.

[0003] When cutting again, doctors mostly use forceps to hold the cartilage and cut the cartilage, but sometimes the overall outer edge of the cartilage needs to be cut (i.e. multiple cutting is needed by adjusting the direction multiple times), and through forceps holding, the operation is relatively inconvenient, and at the same time, the forceps holding may be too tight to cause cartilage damage, too loose to cause cartilage slipping during cutting, which seriously affects the operation quality. Some people also put the cartilage on the instrument box, hold the cartilage with fingers, and trim the cartilage with a scalpel at the same time. This method is easy to cause damage to the fingers of the operator, and it is also inconvenient to cut the overall outer edge of the cartilage, and the operation difficulty is large.

[0006] Further, the clamping part comprises a bottom, a tapered part and a connecting part from bottom to top in sequence, and the diameter of the tapered part is smaller than the bottom and the connecting part.

[0007] Further, the bottom surface of the fixed plate is fixedly provided with a threaded column, the top end of the clamping part is provided with a threaded hole, and the fixed plate is screwed with the threaded column and the threaded hole and the clamping part.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described in connection with the drawings in the embodiments of the utility model. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the utility model, but the utility model can also be implemented in other manners different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the utility model, therefore, the utility model is not limited by the specific embodiments disclosed below.

[0021] Please refer to Figs. 1-2 As shown in the figure, an otic cartilage fascia former includes a fixed plate 1, a clamping plate 2 and a clamping part 3, wherein the fixed plate 1 is a metal material (for example: stainless steel, titanium alloy, cobalt-based alloy, etc., not limited herein) that can be magnetically attracted, the shape of the fixed plate 1 can be circular, square or irregular, in this embodiment, the fixed plate 1 is circular to facilitate the doctor to cut the outer edge of the cartilage or fascia.

[0022] The clamping plate 2 is a magnetic material (for example, a magnet) for magnetic attraction and fixing on the fixed plate 1, so as to magnetically attract and clamp the cartilage or fascia between the fixed plate 1 and the clamping plate 2. Specifically, the shape of the clamping plate 2 can be circular, square or irregular. In this embodiment, the clamping plate 2 is circular, and the surface area of the fixed plate 1 is much larger than that of the clamping plate 2, thereby avoiding the influence of the clamping plate 2 on the secondary cutting of the cartilage or fascia. Preferably, a handle 21 is fixedly arranged at one end of the clamping plate 2 away from the fixed plate 1, so as to facilitate the separation of the clamping plate 2 and the fixed plate 1 after the cutting of the cartilage or fascia is completed.

[0023] The clamping part 3 is fixedly arranged on the bottom surface of the fixed plate 1, and the central axis of the clamping part 3 is collinear with the central axis of the fixed plate 1. In implementation, the clamping part 3 is first clamped by the index finger and the middle finger of the doctor, and then the index finger and the middle finger can move forward and backward alternately during the cutting process of the outer edge of the cartilage or fascia, thereby driving the clamping part 3 to rotate along the central axis thereof, so as to drive the fixed plate 1 at the top end of the clamping part 3 to rotate synchronously. In this way, it is convenient for the doctor to cut the cartilage or fascia by using a scalpel or surgical scissors.

[0024] Specifically, the clamping part 3 includes a bottom part 31, a tapered part 32 and a connecting part 33 from bottom to top in sequence, and the diameter of the tapered part 32 is smaller than that of the bottom part 31 and the connecting part 33. In this embodiment, the bottom part 31, the tapered part 32 and the connecting part 33 are integrally formed, the diameters of the bottom part 31 and the connecting part 33 are substantially equal, and the diameter of the tapered part 32 is smaller than that of the bottom part 31 and the connecting part 33, so that the clamping part 3 has a structure gradually tapered from both ends to the middle, thereby facilitating the clamping of the index finger and the middle finger, and the clamping part 3 is separated and falls off during the clamping process of the index finger and the middle finger.

[0025] Preferably, the bottom surface of the fixing plate 1 is fixedly provided with a threaded column 11, and the top end of the clamping part 3 is provided with a threaded hole, and the fixing plate 1 is screwed with the clamping part 3 through the threaded column 11 and the threaded hole, that is, the threaded column 11 is screwed with the threaded hole. In order to facilitate the disassembly effect after operation or replacement, maintenance.

[0026] In the embodiment, the top surface of the fixing plate 1 is provided with a plurality of annular scale lines 12 with the center axis of the fixing plate 1 as the center, the plurality of annular scale lines 12 are sequentially arranged from inside to outside, and the spacing between the plurality of annular scale lines 12 is equal. By arranging the plurality of annular scale lines 12, the doctor can conveniently refer to the corresponding annular scale line 12 to cut the cartilage or fascia to the appropriate size.

[0027] In the specific implementation of the utility model, the doctor cuts and takes out the cartilage or fascia with scissors, and then places the taken cartilage or fascia on the top surface of the fixing plate 1, and then places the clamping plate 2 above the fixing plate 1. At this time, the cartilage or fascia is magnetically clamped between the fixing plate 1 and the clamping plate 2, the doctor's index finger and middle finger are clamped at the tapered part 32 of the clamping part 3, and then the cartilage or fascia is cut again with surgical scissors or a surgical knife. During the cutting of the cartilage or fascia, the index finger and middle finger can move forward and backward alternately, thereby driving the clamping part 3 and the fixing plate 1 to rotate along the center axis of the clamping part 3. In this way, it is convenient for the doctor to cut the cartilage or fascia with a surgical knife or surgical scissors. At the same time, during the cutting process, the doctor can refer to the corresponding annular scale line 12, thereby conveniently cutting the cartilage or fascia to the appropriate size.

[0028] The above description is only for the preferred embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
